UNITED sTATEs PATENT oEEIcE.
JOSEPH F. LETELLIER, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO FRANCIS LETELLIER, OF SAME PLACE.
STEAM-VALVE.
Specification of Letters Patent No. 30,485, dated October 23, 1860.
To all lwhom it may concern:
Be it known that I, J. F. LETELLIER, of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Governor and Throttle Valves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings and letters of reference marked thereon, in which- Figure l is a longitudinal section, Fig. 2 a perspective of one of the valves.
My invention consists in the peculiar construction of the shell also in combination therewith the governor and throttle valves, arranged substantially in the manner hereinafter mentioned.
To enable those skilled in the art to make and use my invention I will now describe its construction and operation.
(A) represents the shell; (B and C) the governor and throttle valves which operate in the cylindrical case with ports in each, which open and close as the valves oscillate. Said cylindrical case (H) is accurately bored and ground on the inside and is screwed into shell (A) as fully repre sented. It should be observed that the governor valve has six of these ports, while the throttle valve has only half as many. The valves are hollowed and their inner ends entirely open which connect with the opening (Gr).
(I I) are shoulders against which the cylindrical case (H) rests. Said shoulders should be perfectly steam tight.
(D) is a chamber around the shoulders (I I).
In the cup of cylindrical case (H) is screwed a packing or stuiing box (e) surrounded by a jaw nut which acts as a steam joint. Through thisstuiing box passes the valve stem (S).
(d) represents a division in shell (A) which is provided with a step on each side; the inner ends of valve stems extend into these steps as seen in Fig. (l).
(R) represents a bevel surface on stems (S S) corresponding with a similar surface in the stuffing box (v) at this point.
(a a) are spiral springs surrounding the valve stems as fully shown.
(f f) are registers on valve stems (S S).
The operation of my invention is as follows: The valves have a circular motion moving far enough to open and close their ports. The steam enters and ills steam chamber (D) and surrounds cylindrical case. Upon valve (B) coming opposite the ports in the cylindrical case the steam passes through the ports in said case to the inside of valve (B) or governor valves, then passes through the opening (G) to the inside of throttle valve (C), thence from its inner chamber to outside chamber (D) and from thence to the cylinder.
Having thus fully described my invention what I claim is* The shell as constructed and in combination therewith the throttle valve (C) and governor valve (B), all arranged substantially as and for the purpose herein set forth and described. e
JOSEPH F. LETELLIER.
