STRAIGHT READING REGISTER.

The National Meter company has put upon the market a straight reading register so constructed that the figures, which are engraved on the different wheels, appear right in a line. Any child who understands figures will thus be able to read the register without the slightest trouble. No nrevious instructions will be required, and nothing could be simpler. All water departments fully realize the value of a reliable and simple register. Disputed water bills will be a thing of the past. as it will be impossible to make an error in taking the reading. The company has incurred great expense in putting the meter on the market, but the increased sales justify the expectation of abundant business* The company thinks that as soon sis the register is in general service its merits will be fully appreciated. It has been fully tested for accuracy and durability and has proved reliable.

THE COLUMBIA TAFFERS,

Made by the Mueller Manufacturing company of Decatur, Ill., is a practical machine for general use. It differs from the regular Mueller tapper in being cheaper and lighter. The makers do not claim that it is superior to the regular Mueller tapper but they do say that it is equal to any other machine on the market. Better send for a cat a log and examine its merits before going elsewhere.

A PRACTICAL FIFE CUTTER.

An indispensible adjunct of all water works appliances is the Benjamin C. Smith pipe cutting machine. It is simple, accurate and a great time saver. Two men can operate it and it is easily adjusted to auy position. Twothirds of the time can be saved over the old method without incurring any danger of fracturing the pipe. It will cut a twenty-four inch main of the usual thickness in less than twenty-five minutes, a vast saving of time over the old method of doing business. A large number are in use by water departments in leading cities and all give general

ELECTRICALLY CONTROLLED STANDPIPE VALVE.

William Engberg of St. Joseph, Mo., ,is the .inventor and patentee of an electrically controlled valve for a stand pipe. The gate valve in the supply pipe is on the upper end of a piston rod passing through suitable stuffing boxes to a piston head in a cylinder connected by pipes at its upper and lower ends with the casing of a valve in which is a hollow valve plug and the latter is connected by a small pipe with the supply pipe, so that water under pressure may pass to the valve plug. The gate valve and cylinder are fastened together with a frame, as can be seen in the cut. The inside of the cylinder is brass lined and the piston is brass, backed with water tight packing. All tiie operating parts are made of brass and all those ports with tlie magnets and relay are Jn a glass fronted box suitably fastened to the frame.

One ten cell carbon battery is used for magnetizing tlutwo magnets at the {valve, and one four cell battery or more, depending upon the distance to the pumping station for the line.

There is also an electric high water alarm for the stand pipe which will give warning at any point desired by adjusting the setting. The alarm is uneffected by ice in the stand pipe, nor by fast or slow running of the pump.

TIGHT JOINT.

Within a year or two the Tight Joint company of New York has introduced an improved class of fittings known as the tight joint which has proved valuable on high pressure pipes.

The “Tight Joint” is simlliar to an ordinary fitting except a groove is cast in the threaded portion, into which a ring of lead is run. This is formed upon a threaded mandrel of slightly smaller size than the fitting, so that the lead projects a very little beyond the threads. A small hole with a thread cut upon it is made through the exterior of the fitting, into the lead filled recess, and a small set screw inserted. If now a pipe be screwed into the fitting, it will expand the leaden packing, causing it to tightly fill the screw threads, and if the joint is not made tight by this means, one or more turns of the compressing screw packs the lead around the pipes and make the joint absolutely tight.

The “ Tight Joint ” is especially adapted for use in connection with steam, water, air, oil and gas pipes, for hot water and steam heating, hydraulic pumps and elevators, high speed and marine engines, locomotives, vacuum pumps, ice and refrigerating machinery, air brakes for cars and for all pressures where difficulty Is experienced in making tight joints.

In cases where subjected to severe tests the tight joint has never failed to work satisfactorily.

NGN-FREEZING HYDRANTS.

A problem that long bothered water works men is that of preventing a hydrants’s freezing after use. It couldn’t well be prevented because no means was provided for draining off the surplus water. Gregg’s compound nonfreezing fire hydrant solves all difficulties, being at the same time, accessible, reliable and absolutely frost proof.

PIPE TAPPING UNDER PRESflURR-

The Anthony P. Smith machine advertised on another page solves all the problems of pipe-tapping under pressure, which have been so battling to water-works men. The machine allows the flow to go on uninterrupted while the cut is being made. The machine makes connection also, up to the full diameter of the pipe from two to forty -eight inches, a feature which will commend it to waterworks men who have hitherto been bothered about such matters. Fire hydrants can be located and set-up ou lines of mains already in use. Mr. Smith also hits a device for street sprinkling worth the attention of any waterworks man, recently described in FIRE AND WATER.

THE P0H1.E AIL LIFT PUMP.

On another page will be found an advertisement of the lugersoll Sergeant Drill company of New York, giving an illustration and describing some of the principal features, applications and advantages of the Pohle method of lifting water from artesian wells by the means of compressed air. This method is known as the Pohle air lift pump, from Dr. J. G. Pohle, the inventor and patentee, who is now with the lugersoll-Sergeant Drill company, in charge of this department of their business. The economy and advantages of the system recommend it to engineers of water works and all others interested in raising and supplying large quantities of water from deep wells.

The economy with which the Pohle air lift pump may be operated is. to a great extent, dependent upon the efficieney of the air compressor, and it is of great Importance that machinery he selected, which is adapted to heavy and continuous service, with the least delay and expense for breakdowns and repairs. Ingersoll-Sergeant compressors are built in a great variety of patterns and sizes many of which are peculiarly well suited to this service, and in lact, one of the objects of the inventor in associating with-this company was that he might be in a position to furnish such machinry as his previous perience had shown him was, through its own merits, best calculated to increase the efficiency of the pump, and add to its reputation thereby.

A previous experience of several years has shown that there waa no economy or satisfaction in equipping a plant with a cheap machine, as the shortcomings of such compressors were a damage to the reputation of the system. It was found that niany of the cheap and inefficient compressors first sent out had to be replaced before the best results could be realized, and that the repairs, annoyance and delays incidental to their use make up a great many times over, the difference in the first cost between such a compressor and oile which was built for high-duty service, when running continuously year after year. The illustration shows an lugersoll Sergeant air compressor of the “ Straight Line” pattern, class “A,” having piston inlet valves for the admission of air in the cylinder. This system of air admission has proved to be the simplest, most reliable and less liable to breakage of any method heretofore used. One of the advantages of the piston inlet valve is that it permits of a more efficient cooling of the air during compression, owing to the larger area of cooling surface, the water circulating not only all around the air cylinder but through both heads as well. Water works engineers and others interested in the subject should send to the Ingersoll-Seargent Drill Company for one of their illustrated catalogues, describing all these appliances and giving reports from some of the principal places where Pohle air lift pumps have been installed, gives satisfactory results.
