" No 146 057A -Patented Dec.` 30,1873.`
:BENAIAE EITTS, or WORCESTER, MASSACHUSETTS, ASSieNoE To UNION PATENT OFFICE.
WATER-METER COMPANY, OF SAME PLAGE.
IMPRovEMENT IN vALvE's.
Specification forming part of Letters Patent No. 146,057, dated December 30, 1873; application filed November 13, 1873.
To all whom it may commu Be it known that I, BENAIAH Firms, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain Improvements in Valves, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 represents a vertical section taken centrally through a hydrant having my improvement applied thereto; Fig. 2, anelevation of the same; and Fig. 3, a horizontal section through the line .r x, Fig. 2. Fig. 4 represents an elevation of one of the valves detached from the hydrant, and Fig, 5 a side elevation of the same. Fig. 6 represents a plan of the hydrant, a portion being broken oit'.
The nature of my invention relates to anewand improved mode of constructing the valve-seat and valve, and of operating the latter, whereby reactionary or back strain on the supplypipe is averted in opening and closing the valve and it consists in forming the valve-seat with a channel or groove in such manner that when combined with a valve suitably operated and constructed the port will not be entirely closed when `fairly covered by the valve,as communication will still be maintained with the former through the channel or groove, the latter being only iinally closed by a further advance of the valve. For thispnrpose the channel or groove is so formed that as the valve advances the opening through the channel gradually diminishes in its area until it entirely vanishes before the motion of the valve ends, thereby avoiding all back strain on the induction-pipe.
To enable others skilled in the art to make, construct, and use my improvement, I will now proceed to describe its parts in detail.
The shell or case A of the hydrant proper may be made of any suitable size, shape, and material, and may also be provided with one or more openings for water cocks or hosecouplings. In the drawing it is represented as being provided with four of these openings, a a aa, and each of these with a slide-valve, b. The inside surface of the hydrant, where the valves play, is planed flat and smooth, So as to form avalve-seat, as it were, small guidepins c being arranged on each side of these valveseats, to keep the valves in position, and in close contact with the planed face of the seats.
If preferred, guide-grooves maybe used in stead of the pins but the latter answer an excellent purpose.
The valves b are provided at one end with a lug or inwardlyprojecting ange, d, through which is bored-a hole, the latter being then provided with a female screw-thread, so as to act as a nut, into which the Screw-rod d works, which operates the valve. The upper end ot' the screw-rod d is made to project through the cap-piece B of the hydrant, and is provided with a hand-lever, or pulley, or squared end, t', whereby to operate it by means of a key or other device. The screw-rod is formed i with a shoulder or stay-nut, o, or other suitable device, arranged between `the cap-piece B and spider C, to which the cap is secured, and serves to hold Vthe screw-rod in place while operating the valve. The under side of the. cap B is countersunk, to receive stay-nut o.,
The inner end of the openings' a are formed on their under side with an inclined V-shaped `groove c, thereby gradually cutting oi the communication between the hydrant and outlet-port a; or, instead of forming a groove or channel, as just described, the, lower edge of the valve b may be formed with an angular or curved opening,`m, as shown in Figs. l
and 4, for the same purpose; or both-that is to say, groove e and valve b with opening m- 'inay be used in connection with each other,
as represented in Fig. l; and this mode Iprefer. A disk or spider, C, is fitted into the top of the hydrant, and made fast thereto in any suitable manner, and serves as a means of securing the cap B to the case A of the hydra-nt, the cap itself being provided with a o of L hydrant,` provided with zul opening, e, ange, n, t0 assist in forming a Water tight formed in the manner and for the purpose set joint. forth.
