CRANK POST, With Hydrant Attach ment, R. D. WOOD & co.INDICATOR VALVE POST Designed especially for use with Water Valves connected with Fire Service, in Mill and Factory Yards, etc.MATHEWS' PATENT DOUBLE VALVE FIRE HYDRANT. R. D.FIGURE I. CUT-IN SPECIAL. R. D. WOOD & CO.,FIGURE 2. CUT-IN SPECIAL. R. D, WOOD & CO.,

R. D. WOOD & COMPANY,of Philadelphia, who were represented by Mr. Jesse Garrett, exhibited the Mathews’ patent double valve fire hydrants,whose advantages briefly stated are as follows:

Double security against leakage by the use of two main (or induction) valves, one above the other. The lower valve is so constructed that it acts as a supplemental or auxiliary valve to allow the hydrant to be taken up without shutting off the water from the district. The said valve being entirely separate and disconnected from the upper main valve and its rod,and closing automatically when the upper valve is closed, allows the hydrant to be removed without the use of gates, thus avoiding much extra expense and trouble.

The waste orifice is entirely closed before the water is let into the hydrant, and is not uncovered until after the lower main valve Is closed, effectually preventing any waste of water when the hydrant Is in use or only partially open.

Should the upper ( or ordinarily the main) valve be broken or injured in any way, it can be taken off for repairs for any length of time required, and replaced at leisure, without impairing the action of the hydrant, as the lower valve then becomes the main valve, opening and closing perfectly in the usual manner of operating the hydrant, so that the water need not be shut off for an instant from the district, and the hydrant is always ready for use.

The taking out and replacing of a hydrant is done in precisely the same way as with an ordinary hydrant, the lower or auailiary valve being entirely self-acting, and requiring no manipulation whatever in performing its function of shutting off the water.

To secure protection against all contingencies of frost, their hydrant has an outside cast iron casing which is a mechanical part of the apparatus. Besides serving as a protection against frost, this casing also adds strength in the event of any violent stroke, as of a runaway team, and affords constructional finish, giving not only strength but the appearance thereof.

It allows the removal of every working part of the hydrant, such as valve, valve seat, waste apparatus, etc., without breaking ground or obstruction of the street. It receives the force of the upheaval of the grouad from frost, preventing thereby the breaking of connections —a fruitful source of trouble in many towns where such cases are not used.

It contains a column of dead air around the body of the hydrant which as a non-conductor confines the beat of the INDICATOH VALV* POST lower ground and prevents freezing.

It is a cylinder in one section only, extending above the ground five or six inches, preventing the surface water from flowing in and freezing around the hydrant.

The waste is at the side, automatic self-cleaning, absolutely positive, and no sediment or sand can settle there to obstruct it, nor is any secondary motion necessary to operate it.

The hydrant here described can be made with what is called a double valve attachment, which is shown, allowing the removai of the hydrant proper without shutting off any part of the section and depriving the consumers of the use of water during repairs.

This hydrant also shows a nozzle independent cut-off,which is especially desirable in the business section of a town, as with thisdevice it is possible to make a second or a third connection without interfering with the stream first in service.ever it is desirable to note at a glance whether a valve is open or closed.

The indicator valve post is a patented device, designed especially for use with water valves connected with fire service in mill and factory yards, etc.

There is also exhibited by the same manufacturers what is called an indicator post for service in factory yards or where-

This post shows plainly to eve-y passer-by whether the valve is open or shut. It avoids the delay of hunting for a flush-gate-box hidden under snow or dirt, or the delay of opening a frozen gate-box cover. Turning the spindle, I) screws the tell-tale up or down,so proper signs appear at opening of windows in head of post. The square spindle, D, slides freely in a square hole extending through a screw, J. Thus settlement or lifting by frost does not affect tell-tale. There are two tell-tales on opposite sides of post.Letters are one and one-half-inch high, of black enamel, fused on a white ground of porcelain-enamel —very distinct and durable. All bearings and rubber surfaces are rust-proof, being brushed with brass. Screw, J, is only part requiring change to fit the various sizes and makes of valves. In city streets the posts can be set at curbstone line like a hydrant, and thus no obstruction results. A lock-hasp, to seal valve against tampering, furnished, if desired, as an extra.This indicator post can be applied to any ordinary make of valve up to sixteen inches, and is furnished combined with valve or separate, or can be applied to valves already in use.

Another appliance is shown for the filling of sprinkling carts without opening the hydrants, which is a fruitful source of their abuse. It is for placing along the street at convenient points and is rnamental in appearance.

The crane post, with hydrant attachment, is fitted with a stock, frost case, and valve; the parts below the ground-line being the same as used for the Mathews’ hydrant; the valve being controled by a rod and nut from the top.

The post is a cheaper device for supplying sprinkling carts where a combined post and drant is not desired.

In the fall of the year the crane attachment can be removed and an ordinary cap, supplied with this hydrant, put in its place for the winter; the hydrant thus closely resembling the the regular Mathews hydrant.

The weight of the crane attachment necessitates a heavier base, hence it cannot be applied to the regular Mathews, hydrant.

R. D. Wood & Co. likewise exhibited cutting-in specials (Dunham patent, 1892), of which they are the sole makers. /

These are made in four-inch to twelve-inch sizes, inclusive, .and especially adapted for use where it is necessary to cut a street main for setting an extra hydrant, the opening of a new street, or for the introduction of any other large service.

EAST END HYDRANT ARRANGEMENT,—NEW YORK TEST.

Figure I illustrates the method commonly employed for cutting water and gas mains where large tapping machines are not available.

Figure 11 shows very clearly the advantage of the cutting-in special, one end of which is enlarged at the’back of the bell, face of which is slightly oblique to the axis of the special, thus making it possible to insert it readily as shown and necessitating but two joints. At the back of the bell and parallel to its face is a thin projection or rib, which fits the main pipe and forms an excellent stop for the yarn when the special has been brought into its proper position. The special is to be so made as to be adapted to pipes of varying thicknesses and presents no difficulty in “ making up.’

Aside from the advantage of diminished excavations and the saving in joints and labor, the use of the cutting in special will materially lessen the length of time the water must be shut off, as, with the special at hand, the length of pipe to be cut from the main is readily determined and may vary an inch or two without causing trouble; the holding and blocking up of pieces incident to the old method being avoided; and, when complete, the finished work has the fewest possible joints. In smaller cities and towns, and in those portions of large cities where but little risk and inconvenience attends the brief shutting off of the water supply,this cutting-in special offers the least expensive method of making new connections. The cutting-in special may be used as a common special, if necessary,and in ordinary pipe laying,where there is any uncertainty as to the location of side streets or hydrants, it will be cheaper to make the work continuous and “cut in” branches with this special as required. R. D. Wood & Co., make short lengths of pipe with the patented bell and a spigot, or with the patented bell and an ordinary hub end. Where a change in direction either for grade or alignment is not sufficient to require a curved pipe, thoroughly good work can be secured by using one of these short special pipes. Where breaks in a pipe system occur, repairs can be made without a sleeve with the least excavation and with but one extra joint.

In addition to the cuts illustrating the above article, there is given a view of the east end arrangement of hydrants, etc., in the corporation yard. It shows standing on the platform (beginning from the right hand side) Chief Bonner, Water Purveyor North (in the centre), and Col. Gear (on his left), with Chief Engineer Birdsall half hidden by a hydrant post.

(To be eontitiued.)

So efficient is the fire department of Cleveland, Ohio,under Chief Dickinson, that the local board of underwriters has reduced the basis rate in that city from forty to thirty-three cents, which will make a difference of from ten to fifteen per cent, on risks in the congested or business portion of the city.

(Continued from last week.)

COFFIN IMPROVED GATE HYDRANT.KENNEDY VALVE INDICATOR POST.KENNEDY SECONDARY STOP VALVE.

THE Kennedy Valve Manufacturing Company, of New York, had a fine display of hydrants, valves, and other appliances on hand. The exhibit was looked alter by D. Kennedy, P. Hartenfels, and M. Gilmore.

The company’s exhibit consisted of compression hydrant, with patented secondary stop valves, gate hydrant, patented indicator post valve,indicator valve stand,bell-end water gates, with inside screw and outside screw and yoke.

The compression hydrant, with secondary stop valve, is a new addition to the many specialties manufactured by this company; is so constructed that in case of obstruction in the valve or for necessary repairs the valve, valve seat, and drip valve may all be easily drawn out of the top of the hydrant, leaving the standpipe undisturbed, and may be replaced in a few moments, thus obviating the necessity of digging up the street or disconnecting the standpipe from the water main. A very important feature of this hydrant is the ease with which the valve seat may be removed; and, as this is the part of the hydrant which,more than all others, is subject to hard usage, it is essential that it be accessible. Therefore, should the cvalve seat become marred or in any way cut up, it may be easily taken out, repaired, and quickly returned to its place, when the hydrant will be practially as good as new. The drip is positive; for, when the main, SUPPLEMENTARY valve opens, the drip closes, and when the main valve closes, the drip opens ready to drain the water from the standpipe; thus preventing all danger of freezing. The above are very important features.

The valve seat, stem, stem nut, and drip valve are made of gun metal. The main valve is made of the company’s special quality of rubber, or of leather, if preferred, and may always be relied upon to make a perfectly tight joint. The secondary stop valve is a new feature in the construction of fire hydrants, and does away with the necessity of shutting off the water main in case of any repairs to the hydrants.

This is certainly a great improvement, and should not be underestimated, as in ordinary cases, when repairing a hydrant, it is necessary to shut off the water main, consequently disconnecting several hydrants; whereas in this case every hydrant manufactured by the Kennedy Valve Manufacturing Company acts independently of all other*. The secondary stop valve is controled by the main valve, both opening against, and closing with the pressure, thus shutting off the water from the main inlet in case it is necessary to take out all working parts of the hydrant, which in this case can be accomplished without obstruction or digging up the street. The main working parts of the hydrant are so arranged that one man can with ease remove and replace the same without any hoisting device in two minutes—a point which was fully demonstrated at the exhibition.

The water gates exhibited by this company are improved double gate. The internal mechanism of the valve consists of two parallel disks, which are forced to the seats when the valve is closed, by the aid of two inclined planes or sections of a right and left-hand screw with abrupt pitch. These screws are forced by the last turn of the stem on stops or lugs which operate the screws simultaneously and expand the disks tight to the face. When opening, the first turn of the stem releases the screws, and the gates rise and fall with the stem. The stem and screws are of the best steam metal. The gates are cast iron faced with brass rings. The valve seats are made of the best bronze screwed in the body to the shoulder, which makes a faced joint; the valve faces and valve seats are ground in place and made perfectly tight.

The valve indicator post is designed expressly for water valves, connected with street mains and for use with valves for fire service in mill and factory yards. The turning of the nut N which is screwed on the valve stem, raises and lowers the band T round the post. This band covers either ihe words ‘“Open” or “Shut,” which are fixed on both sides of the post, and will positively indicate whether the valve is wholly or partly opened or closed. All the moving parts and letters are made of brass and cannot rust or be easily broken. It can be used in any street or yard, as it cannot easily be put out of order, or be manipulated without the aid of a key, which can be kept at a convenient place.

The Kennedy gate fire hydrant is possessed of several important advantages. 1st.—It has a very large percentage of valve area, allowing four nozzles to be used at the same time; 2nd.—-In case of obstruction to the valve or for necessary repairs the main gate, drip valve, stem, and stuffing box can be taken out intact, and replaced in a very few minutes without breaking any joints by simply removing the cap. This does away wish the inconvenience which arises from excavating round the hydrant and avoids all obstruction and repairing of the street. 3d.—It has a specially excellent arrangement for draining the standpipe to prevent freezing when not in use. The drain or drip valve is attached to the main stem, which enables it to be removed WRENCH ,N with the gate, and is APPLIED MERE–^ S’ operated by a reverse thread from that which operates the gate on the stem making the action simple and positive, closing, when thegateopens, and opening, when the gate closes to drain the standpipe. 4th. — The gate valve can be faced with brass or hard rubber, if required. 5th.— This hydrant can also be arranged to have one steamer and three hose nozzle valves, which can be operated separately and independently, all*’ four being under the control of the main gate. All the parts are interchangeable, and can be replaced when worn out and put in working order in a very short time.

In addition to the cuts illustrative of the exhibits referred to under this, and the succeeding heading, there is given a view of the arrangement £ of the hydrants exhibited in the corporation yard during the recent test.

THE COFFIN VALVE COMPANY,

of Neponset, Mass., was not represented at the test. The Coffin hydrant and gates were on view, and they were subjected to the same testsj t_ ⅝ $ as the other appliance, the Coffin hydrant.

These hydrants arc finished with any depth of cover, any size and number of nozzles that may be desired, and are made to connect with the water main by cither hub, flange, or spigot. The valve is of solid composition or bronze metal, and is operated by a composition nut at the top of the hydrant. In dosing, the valve is forced to its seat by an iron wedge faced with composition, and is absolutely tight; and at the same time the water is slowly shut off, thereby preventing any water hammer or strain upon the pipe. .

When oneninff the valve is lowered into the bottom Of the hydrant, leaving a clear and unobstructed waterway. The smallest diameter of the water way is at the seat, which in the four-inch hydrant is four-inches, and the area throughout the remainder of the hydrant is twenty-five per cent, larger than the diameter of the seat opening.

All bearing parts are of composition, and every piece is interchangeable; parts for repairs being quickly furnished. The seats, nozzles, and bushings are screwed in,which in case of accident can be screwed out and others replaced with facility.

The hydrant is made in three parts, viz: the top, standpipe, and bottom, which are bolted together. In case of repairs this method adds greatly to the convenience of an examination.

It is also anti-freezing, being drained by two wastes situated on opposite sides of the hydrant below the water main; these wastes serving as a guide for the valve.

When the hydrant is opened, the escape bole for the water is immediately closed, and remains so until the valve is again shut, when it is uncovered, allowing the water to flow out.

The valve and wedge are constructed with such taper as to prevent the valve being stuck to its seat. They can be easily operated at all times without regard to the length of time it has been unused.

Frost cases are furnished to those who require them. They are often advantageous to hydrants set in clay soil; for in the spring, when the earth is heaved by the frost, the frost case is then moved upwards instead of the hydrant; and this precaution prevents breaking a joint, or, perhaps, the pipe.

Many use the supplementary valve, as shown in the accompanying cut.

It is bolted to the hydrant bottom in place of the usual connection, and in case it is necessary to take up the hydrant it can be done without shutting off the water from the main.

All hydrants are tested to a cold water pressure equal to 300 feet head before leaving the works.

Although only a four-inch gate hydrant is shown here, the Coffin Valve Company makes three-inch, four-inch, five-inch, and six-inch hydrants, with or without independent nozzles, and also all styles of plug and flush hjdrants.

Buffalo, N. Y., will gain about $50,000 this year by the house to house inspection of the bureau of water. Many taps not paid for have been discovered in the houses of the wealthy people on Delaware avenue and other fashionable residence streets. Among the poorer people only one or two have been found who have attempted to beat the city in this respect. One wealty man on Delaware avenue put every difficulty in the way of allowing the inspectors to enter it.
