E G. CAMPBELL AND HENRY E. CAMP- WATER-SUPPLY SYSTEM FOR FIRE PUMPS OR ENGINES.

SPECIFICATION forming part of Letters Patent No. 518,776, dated April 24, 1894.

Application filed January 23, 1893.

To all whom it may concern:

Be it known that GAEDINEB CAMPBELL, deceased, and GEORGE G. CAMPB LL, both of the city of'Milwaukee, in the county of Milwaukee and State of Wisconsin, did jointly invent new and useful Improvements in Water-Supply Systems for Fire Pumps or Engines and we HENRY C. CAMPBELL, executor,

and ISABELLA CAMPBELL and MINNIE A.

re MILLARD, ne CAMPBELL, executrixes of the said GARDINER CAMPBELL, deceased,and the said GEORGE G. CAMPBELL, do hereby declare the following to be a full, clear, and exact description of said invention, reference being I 5 had to the accompanying drawings, and to the letters of reference marked thereon, which I form a part of this specification.

Our invention relates to improvements in water supply systems for. fire. pumps or engines. I

The object of our invention is to provide a more copious supply of water from the hydraulicmains of a city than can be obtained from the ordinary hydrant, and also, wherebythe numberv of engines supplied at a given place, is not limited to the number of hose connections of the hydrant.

The construction of .our invention is explained by reference to the accompanying" outlet valves of the water reservoir, drawn online 4-4 of ,Fig. 5. Fig. 5 is a side view of 40 the device shown in Fig. 4,-drawn on line 5--5 ofsaid figure. Fig. ,6; represents a cross section of an adjustable discharge duct, drawn on line 66 of Fig. Fig; 7, represents a bottom view of the coyer ofthe reservoir.

5' Like parts are represented by the same reference letters throughout the several views.

A is a metallic reservoir which is prefer-' toward the right or left until it'is Serial No. 459,500. (No ore.)

ably made of cast iron in a series of sections B--BB, the upper edge of each section being enlarged to receive the lower edge of the next succeeding section above it. The upper section C converges slightly'forming a short neck which is provided with an annular flange D for the reception of the cover E. It is obvious that by thus forming the reservoir of separate sections as shown, the height of the reservoir may, by adding or removing a section, be varied to conform to the level of the streetor to any change made in grade of the I street after the reservoir is set, it being intended to locate the mouth of the reservoir at or near the level of the street, while the bottom of the reservoir is located at or near the level of the water main.

F is the bottom of the reservoir, which is provided with a vertical, annular flange G, which incloses the lower edge of the lower section B.

Water is conducted to the reservoir Afrom the hydraulic mains through the S shaped pipe or duct H. The duct His formed in the peculiar angular shape shown to facilitate connectingthe reservoir with water mains located on different planes. When the water main is above the inlet aperture of-the reservoir-the pipe H is turned upward in the position shown. When the water main is below, the free end of the pipe H is turned downward and when the water main is located at any intermediate level between the two extremes, the free end of such pipe is turned brought in line with the water main, whereby said pipe has a range of adjustment of several feet upward or downward, which connecting the reservoir with the water mains as stated.-

J, is an ordinary gate valve, by which the admission of water from the water mains is controlled and regulated. I

.K, is a valve rod which communicates from the valve to near the upper end of the reservoir, at which point it is provided with a removable handle L, by which the rod is turned greatly facilitates toward the right and left and the valve thereby opened or closed. a l

To prevent turning the valve rod in the wrong direction as might otherwise be attempted in the haste and excitement of opening it in case of fire, the upper end of the rod K is provided with a ratchet wheel M against the teeth of which the pawl N engages insuch a manner as to prevent said rod from being turned downward. WVhen, however,it is de sirons to close the gate valve the pawl N, is thrown back out of contact with said teeth. WVhen the reservoir A is not being used it is desirous to permit the water to escape therefrom. To accomplish this obj cot,- the valve 0 is provided, through which valve when open, the water flows into the horizontal duct P, to the sewer. The duct P, is preferably cast contiguous with the bottom F. The valve 0 is held open when the reservoir is not in use by the chain Q, which chain is suspended through the handle R within the recess S, which recess is formed in the edge of the bracket T. The lower end of the handle B is provided with a collar, U, which engages on the upper side of the pawl N, whereby said valve 0 is prevented from closing of its own gravity. Lest it might be forgotten to close the outlet valve 0 before opening the inlet valve, the handle R is made to depend for its support in said recess upon said pawl N. It follows that as soon as the valve rod of the inlet valve is turned in the act of opening said valve, said pawl is thrown back from said suspended handle Rby contact with the'teeth of the ratchet wheel L, whereby said handle is released and said valve 0 is permitted to close.

A is a cap or shield located above, in front, and partially around the discharge duc'tof the valve J, and is so constructed as to stop the force and agitation of the water as it rushes in from the water mains, and prevents the whirling movement which would inter fere with the proper Working of the fire pumps. The cap A is rigidly bolted at one end to the discharge duct of the valve J and rests at the other end upon th bottom of the reservoir. 1 To prevent the reservoir from over-flowing by the excess of the supply of water over the capacity of the fire pumps, a discharge pipe B is provided, the mouth of which is located or adjusted at the desired level of the water in said reservoir, whereby, when the water reaches suchlevel the excess will over-flow into said discharge pipe, from whence it es:

capes out, throngh the duct P, to the sewer.

As an additional means for maintaining the water at the desired level in thereservoir', a secondary valve 0 is provided at the dis? charge end of the valve J, which valveC' is fitted loosely in its bearings so as to be easily moved by the automatic action of a floatand counterbalance; it not being intended to entirely stop the inlet of water thereby but only to diminish the flow to correspond with the quantity'drawn from the reservoir, the valve 0 is suspended from the lever D. The lever D is centrally supported by the standard F upon the pivot G. The free end of the lever D is provided with an adjustable weight H, which counterbalances the valve 0' and causes it to remain in the open position. The float I is connected with the free end of the lever D by a chain J, whereby as the water in the reservoir rises above the level of the discharge pipe 13' the float will be buoyed up, when acting through the chain J, and lever D will close the valve 0', Thus, it is obvious that the valve 0 will be caused to open and close to conform to the change of level of the surface of the water and a nearly uniform level of water be thereby maintained in the reservoir. To provide for protecting the valve and inlet dnet's'fro'r'n injury by frostthe valve J is partially opened to admitasmall stream of water when the valve K is opened whereby when the water hascovered the inlet valves and ducts and reaches the level of the valve K'it escapes from the reservoir through the pipe B.

The valve K is provided with a chain L by which it may be opened and closedfrom the mouth of the reservoir.

The vertical pipe or duct B is preferably formed in two sections afand b, one of less diameter than the other, which-are telescoped together so as to adjust its inlet end to any desired level. When thesection b is adjusted it is secured at such point by set-screws cZ-d as shown in Fig. 6. l 1 It is obvious that by forming the reservoir A in sections as shown, the pipe connecting section or section by which the inletpipe is connected with said water mains, may be located either at the bottom of the reservoir at any intermediate point between the bottom F and the converging top 0, to correspond with the level of the said water mains, without changing the relative position of either the top or bottom of the reservoir to each other or to the surface of the ground.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
