WMZ'. 07-.6 5 g UNITED STATES PATENT @FFICEo RUFUS N. PRATT, OF HARTFORD, CONNECTICUT, ASSIGN OR TO THE STEAM BOILER APPLIANCE COMPANY, OF SAME PLACE.
STEAM-VALVE.
. SPECIFICATION forming part of Letters Patent No. 257,449, dated May 2, 1882. Application filed Novcmberl i, 1881. (No model.)
To all whom it may concern Be it known that I, RUFUs N. PRATT, of Hartford, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement in Steam-Valves, of which the following is a description, reference being had to the accompanying drawings, where- Figure 1 is a side view of a steam-valve constructed in accordance with my invention. Fig. 2 is a view of the same in central longitudinal vertical section. Fig. 3 is a view in central longitudinal section of a valve of equivalent construction.
My invention consists of the peculiar arrangement and combination of the parts of a straight-way fluid-cock, the valve-seat being arranged at an angle (usually about forty-five degrees) with the main barrel of the valve, and integral with it, the valve-seat accessible by means of an opening in the barrel directly opposite the seat, and the flap-operatin g rod so arranged as to thrust directly over and upon the flap and the appurtenant valve pressing the latter to its seat.
The letter ain the accompanying drawings denotes the body or barrel of the valve intended to be interposed in a line of pipe in the usual manner.
The letter 1) denotes the swinging valve as a whole, (meaning thereby to include whatever forms the valve which comes in contact with the valve-seat and theflap,) pivoted on the screw-pin 0, or in any other common nanner, and cooperating with the valve-seat d.
The swinging flap in the form shown in Figs. 1, 2 is provided on its back with the mortise c, and the rotary flap-operating rod f is provided with a foot, j", which meshes into the mortise and serves to operate the flap, at the same time being allowed to rotate.
The barrel a is provided with a tubular branch, g, for the entrance and support of the flap-operating rod, closed by the usual screwplug, h, bearing the common stuffing-box, '5. j denotes the hand-wheel on the flap-operating rod. The barrel is also-provided with an open ing, 7:, closed by a screw-plug, Z, the ofiice of which is to give access, for the purpose of forming the valve-seat, to the seat and flap from a dili'erent direction than that afforded by the tubular branch 9, and from the nature of its office it must be located opposite the valve-seat.
The swinging flap bears the rotary valveface m, made of any suitable material, and so connected with the flap as to be readily detachable to repair or replace. On the back of the valve face or disk at there is a short pin or shaft, with its end slotted like the head of a wood-screw, and for a similar reason or purpose. By unscrewing the plug la screw-driver blade can be inserted through the opening into the slot at and the rotary disk ground to its seat.
In Fig. 5 I illustrate another method of combining the flap and its operating-rod so as to secure a direct thrust upon the flap and valve-face. The direct thrust of the operatin g-rod upon its seat on the flap when the lat- 7o ter is closed secures a perfectly-tight valve, which has never before been done where swinging flaps have been used in connection with spindles or operating-rods.
Another advantage of my invention is that I secure in a straight-way valve the feature of the accessibility of the valve disk and seat for removal and repair without removing the whole valve-body from the pipe on which it may be placed.
I claim as my invention- I. In combination, in a fluid-cock, a barrel, (1, having branches 9 and k and inclined valveseat d, with a swinging flap, b, and operatingrod f, all substantially as described, and for the purpose set forth. M
2. A fluid-cock having a barrel, (1, inclined valve-seat d, branch 9, and branch is, all substantially as described, and for the purpose set forth.
