Description
UNITED STATES SAMUEL REID, OF CHICAGO, ILLINOIS.
IMPRQVEMEN T IN BALANCE SLIDE-VALVES.
Specification forming part of Letters Patent No. 141,728, dated August 12, 1873; application filed May 26, 1873.
To all whom it may concern Be it known that I, SAMUEL REID, of the city of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Balanced Slide- Valves for Steam-Engines, of which the following is a full description, reference being bad to the accompanying drawings making a part of this specification, in which- Figure l is a vertical section, showing the several parts placed at a little distance from each other; Fig. 2, a plan view of the metal ring.
The object of my invention consists in pro viding an expansive steamjoint between the valve and saddle-plate, by the use of which the parts fit in their places with sufficient tightness, and compensation for wear is provided for. This expansive steam-joint consists of a hollow metal ring having a slot around its periphery, which ring is located between the valve and saddle-plate.
In the drawings, A represents the valve; B, an extension thereof, in the top of which extension is a groove, a, the depth of which is somewhat less than one-half the diameter of the ring it is to receive. 0 is a hollow metal ring, having a slot, d, in the outer periphery thereof. D is the saddle-plate, having an extension on the lower side, which extension is made to fit in a corresponding recess, h, in the part B of the valve. In the under side of the main portion of the saddleplate D is a groove, b, corresponding in size with the groove a in B.
When the parts are in position for use, the ring 0 is placed in the groove a, and the saddle-plate D rests upon the upper surface of the ring 0, the groove or recess b fitting the same, the saddle-plate D being beneath the lid of the steam-chest, and fitting the same in the usual manner.
In manufacturin g these three parts A G D,
I make them of such thickness that when they are all in their proper position between the valve-seat and the lid of the steam-chest, the ring 0 will be somewhat compressed, so that the pressure of the steam within the ring 0 will keep the valve A to its seat, and the saddle-plate D up against the lid of the steamchest, even though the parts should wear away somewhat by continued use.
In order that the pressure of the saddleplate against the lid of the steam-chest may not be too great, I cut away such portions of the upper part of this plate as may be neces sary, as represented at c. The part g of the saddle-plate fitting within the part h of the extension B, it (the plate) will be carried along with the valve.
The ring 0 may be made of any suitable metal, or of vulcanized rubber, or any other suitable material, its thickness depending upon its size and the pressure-to which it is to be subjected.
What I claim as new is as-f0llows:
The hollow ring (J, having a slot, d, extending around it, in combination with the valve A and saddle-plate I), all constructed substantially as and for thepurposes specified.
' SAMUEL REID.
