JOHN HUGH MCCOY, OF HARRISVILLE, PENNSYLVANIA.

CONCRETE WATER-TANK.

Application led August 2 To all whom it may concem:

Be it known that I, JOHN H. MCCOY, a. citizen of the United States, residing at Harrisville, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Concrete fitter-Tanks, of which the following is a specification.

My invention consists of an improvement in water tanks or the like for the purpose of maintaining a supply of water at a desired height above any suitable receiving level as for instance, the tracks of a railway.

The invention is designed to provide a tank of such character constructed of concrete or cement, having a lower supporting base structure and an upper tank portion mounted thereon, with a central inclosed supporting pier for the reception of the various pipes whereby the water delivered to and vfrom the tank is protected from the effects of temperature, and also incased within the said pier, whereby to permanently install the pipes or conduits therein.

A further object .of the invention is to provide radially arranged supporting elements embedded in the lioor structure, with associated reinforcing members, together with other features of construction and advantage as shall be more fully hereinafter described.

In the drawings t-Figure 1 is a central vertical sectional view through an entire tank apparatus. Fig. 2 is a transverse sectional view on the line II. II. of Fig. 1. Fig. 3 is a similar view enlarged, of aportion of the iioor construction, indicated by the line HI. III. of Fig. 1. Fig. 4 is a detail plan View showing several of the radial Hoor supporting and reinforcing elements and the bearing plates therefor, with relation to the inner and outer vertical supporting pier and wall respectively.

Generally stated, the entire structure consists of a cylindrical wall 2 of cement or concrete extending upwardly from the foundation or base, having annularly arranged reinforcing members 3 of any suitable kind and well understood in the art of reinforced concrete. rIhe wall 2 preferably tapers upwardly as shown, to the point where the floor 4 of the tank structure proper is supported upon it.

Centrally of the wall 2 and extending upwardly above the base or foundation 5, which may be integral with the walland the Specification of Letters Patent.

central pier as shown, if desired, is the central supporting pier 6, also of concrete, which is preferably made cylindrical and which constitutes the central support for the floor structure 4, with an intervening surrounding space 7 between the pier and outer wall 2.

8 represents floor beams extending radially from around the upper edge of pier 6 to and over the wall 2 as shown, which beams are preferably steel I beams or of other' suitable structural form. Each end of each beam 8 extends outwardly and inwardly respectively beyond the edge of wall 2 and pier 6 sufficiently far to provide a substantial bearing, and below each end of each beam as shown is placed a bearing plate 9 and 10 respectively.

As shown in Fig. 4, a plate 9 is provided more closely adjacent inner ends of two or more of said beams 8, rest upon a single plate 10, said plates being located closely together in circular arrangement, to provide for such support. cated are completely embedded in the floor 4, which extends upwardly beyond the beams and also below them as shown, a suiiicient distance to provide ample strength and body, whereby to insure rigidity and continuous efficiency. The size and proportions of the beams, thickness of the floor, etc., are controlled by the other proportions of the structure, its capacity, and other local con` ditions within the province of the builder.

Supplemental reinforcing bars 11 of any suitable construction, but preferably corrugated, twisted or other deformed bars, preferably having retaining heads 12, are laid alternatelybetween the outer portions of the beams 8, in radial arrangement, extending inwardly for a portion of the distance across the space 7 the outer portions and heads 12 being embedded in the wall structure, whereby to tie the concrete and to further reinforce the structure at the wider portions of the spaces between the beams 8, as will be readily understood.

The tank structure proper, above the floor 4, consists of the upper circular wall 13 extending above its juncture therewith, flush with the exterior of lower wall 3 and preferably tapering slightly inwardly toward the top as shown. The tank wall 13 is similarly reinforced by embedded annular tension members 14 of any well known con- The beams S as thus lofor the outer end of each beam 8, while the sion members, greatly relieving the concrete f vof tension strains, and more positively maintaining it in position to resist compression strains. The tank structure may be covered with a roof of any suitable design and may be provided with any .other attachments or features as a ladder 15, whereby to facilitate its operation, inspection, etc.

1G represents an overflow pipe terminating at the desired normal level of the water and 17 is the intake or supply pipe, preferably Aterminating slightly above or at the same level with the overflow pipe as shown.

18 is the discharge pipe, preferably of larger size .than the overflow and intake pipes, terminating at the middle bottom portion of the water chamber and flush with or slightly lower than the lowermost portion of the floor. Said floor as shown, preferably tapers slightly downwardly toward the center to insure drainage.

The overflow, intake and discharge pipes may be of metal of ordinary construction continuously through the central pier 6, if desired. If preferred however, those portions .of said pipes which are embedded in the pier 6 below the surface of the floor 4 may be of tile, wood, or other material, and a special advantage of thus embedding them is that the concrete structure of the pier which surrounds the pipes will maintain the circulation space, quite independent of the destruction of the pipes themselves, due to any cause as rust, decay, etc.

It will be understood that the overflow, intake and discharge pipes may be connected in any suitable manner with other suitable supply or discharge pipes at the base yof pier 6, as indicated in the drawing, without further description.

The construction is generally similar to that shown in my co-pending application for concrete water tank filed February 25th,.

1910 Serial No. 545951, of the double-wall type.

The advantages of the construction will be appreciated by all those familiar with this class of apparatus. The material employed is practically indestructible and not subject to decay from moisture or changes in temy perature The central pier provides an am- Y YYple and suitable support for the weight of the tank, floor and contents, thereby obviatesapsi ing the necessity of complicated expensive framing. The embedding of the several pipes within the central pier with the outer inclosed main wall 3 and the intervening air chamber, completely protects the pipes from the weather, so that with the frequent circulation of the water incidental to the customary use of the tank, all freezing is obviated and the tank is thus capable of continuous service independent of changes in temperature.

The invention may be variously changed or modified in different features or details by the builder or skilled mechanic, but all such changes are to be considered as within the scope .of the following claims.

hat I claim is n 1. In a concrete water tank, the combina-f tion of a circular foundation wall, acentral 1., pier, radially arranged floor beams free from each other rest-ing by their free ends over 85 said foundation wall and said pier respectively, separate bearing elements for the` floor beams, reinforcing members free from each other extending radially inward between the outer portions of said floor beams, a floor incorporated with said beams and re- -inforcing members, and a circular tank wall extending above said floor and circular foundation wall having inclosed within it annular reinforcing members, substantially as set forth.

- 2. In a concrete water tank, the combination with an outer circular foundation wall and a central pier, of annular series of bearing plates embedded in the concrete over 100, said wall and pier respectively, radially arl ranged floor beams laid on said plates, intervening radially arranged reinforcing members extending inwardly between the outer portions of the floor beams, and a floor laid over the foundation wall and pier and inclosing the beams and plates, substantially as set forth.

3. In a concrete water tank, the combination of a central pier, an outer circular foundation wall surrounding said pier with an intervening annular space, radially arranged floor beams free from each other resting by their free ends over said foundation wall and the outer end of said pier respectively and bridging the annular space, annular reinforcing members embedded in the outer wall, and vertically arranged circulation pipes embedded in the central pier within the inner ends of the iioor beams, substantially as set forth.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
