Stop-Valve.
Patentd June t8, 18.72.

UNITED STATES RICHARD BEAUMONT, OF MOMENCE, ILLINOIS.
IMPROVEMENT IN STOP-VALVES.
Specification forming part of Letters Patent No. 127,951, dated June 18, 1872.
To whom it may concern:
Beit known that I, RICHARD BEAUMONT, of Momence, in the county of Kankakee and State of Illinois, have invented a new and useful Improvement in Water-Valves; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, and being' a part of this specication, in whicl1- Figure 1 is a front elevation of my valvecase with the valve-bonnet removed; and Fig. 2 is a cross-section of the same, showing the bonnet detached.
Like letters refer to like parts in each figure.
The nature of this invention relates to an improved, simplified, and cheapened construction of Water-valves; and it consists in the peculiar arrangement of a pair of wedges on the inner face of the valve-bonnet in connection with corresponding inclined surfaces on thev back of the valve, whereby the latter is forced against its seat, and thus prevents leakage.
In the drawing, A represents the case of my valve, in the lower part of which is an outlet surrounded with a collar or coupling, A. The inner face of this outlet forms the valveseat, and in the opposite side of the case there ground to its seat whenever required. .F is a threaded valve-stem, secured at its lower end to the valve, its top projecting up through the top ofthe valve-case, in which revolves a hand-wheel, G, threaded vin its hub to engage with the screw of the said stem; by means of which or any equivalent device the valve may be raised from or lowered to its seat. On the back of the valve there are formed therein two vertical recesses, @one at each side, whose faces are inclined, as seen in Fig. 2. On the inner face of the bonnet there are two wedges, b, the ends of which are inclined to correspond with the inclination of the faces of the recesses a, into which they project, so that as the valve is forced down by its screw it will also be forced against its seat. The bonnet has an opening surrounded by a collar or coupling, C', having the same bore as the other, A', so that when the valve is raised the fluid will pass through the valve-case in a direct line.
By the construction of the valve and case in themanner described the cost thereof is reduced nearly or quite one-half as compared with the ordinary gate-valves, as all the titting up is done in a lathe.
What I claim as my invention, and desire to secure by Letters Patent, is-
The construction and arrangement of the case A, bonnet O provided with the wedgestuds b, and the valve E provided with the inclined recesses d and actuated by the stein F, substantially in the manner described.
RICHARD BEAUMONT.
