Setting Up Wooden Tanks.

One of the facts of the W. E. Caldwell Company’s catalogue is devoted to methods of setting up wooden tanks, which should prove both interesting and valuable to the water works man who either uses or oversees the setting up of wooden tanks for any purpose whatever. The illustration shows steps in the work from the time the floor beams are laid to the point where the last hoop is in place.

Fig. 1 shows how the bottom of the tank must be supported by sub-joists— no weight must be supported – by the staves; Fig. 2, dressing a thin shaving off the edge of the bottom to make a driving fit with the croze in the staves; Fig. 3, carefully fitting the last stave; Fig. 4, putting the first hoop on when the bottom enters the staves; Fig. 5, tank completed and ready for painting. The Caldwell Company manufactures a complete line of tanks, both wooden and steel, and the catalogue gives extensive data about all which should prove useful in the hands of any water works man employing water tanks. The Caldwell Company, which is located at Louisville, Ky., will gladly send a copy of the catalogue to any water works superintendent or manager. Mention this journal when writing.

Assembling a Wood Water Tank.

The Quadruple Denver Siren.

The siren manufactured by Hendric & Bolthoff, of Denver, has pushed itself into favor in a great many places on account of its effectiveness as a fire alarm. The report from the D. A. Woodhouse Manufacturing Company, New York agents for the sale of the appliance, proves this and shows that a fi e tool of real merit is bound to find a market amongst the people interested in effective service for protection from lire. The report says: Great Neck, N. Y., contracted for two quadruple Denver sirens and two H. F. D. automatic controls, so as to give them two selective signals, one to be used for fire alarm and the other for an assembly or police call, or guard call in connection with their home guard, and it may also be used as a general alarm. As a fire alarm signal it will blow ten seconds, then died down for four seconds, then sound again for two seconds, die for four seconds, then repeat ten seconds, etc. For the general alarm or any other alarm that may be desired the siren will blow for two seconds, and off for four seconds, and repeat, giving a regular series of blasts. This system can be used from any number of points. In fact, it can be operated from an unlimited number of places, and can be wired from one to fifty locations, as desired. By this latest control attachment in connection with the Denver sirens they can be worked in connection with the home guard and fire alarm purposes as desired, or police signals as mentioned. Homer, N. Y., and Kcnmore, N. Y., have recently installed the H. F. D. control systems in connection with their Denver sirens in service. It might be mentioned that Denver sirens have recently been installed by Highland, N. Y.; Athens, N. Y.; Lindenhurst, N. Y.; New Hyde Park, L. I., N. Y’.; Point Pleasant, N. J.; Secaucus, N. J.; Kenmore, N. Y.; Babylon, N. Y.; Boonville, N. Y., and Cuba, N. Y’. The Woodhouse Company will be pleased to demonstrate the working of this really effective fire alarm at any time and will send descriptive matter fully explaining its operation, by addressing 64 West Broadw’ay, New York City.

A Reliable Reducing Valve.

The Ross Valve Manufacturing Company, of Troy, N. Y., manufacture a complete line of pressure reducing valves both for small and very large services. The large reducing valves are used to control and regulate pressure or gravity systems, to regulate flow between reservoirs located at different levels, or to maintain or relieve pressure on pumps or pipe lines. That the Ross pressure reducing valves have given satisfaction is vouched for by the fact that the sale of them has steadily increased from 870 until the present date. These valves have the benefit of 38 years of experience which the manufacturers have had in this particular line. A little booklet descriptive of reducing and regulating valves for water works has been prepared by the Ross Company for distribution. It should prove very useful to the water works manager. A copy will be sent to any water works man on request.
