SAFETY VALVE. (Application med sept. 2s, 1899.)
W E T N E V IN E n\\\\\\\\\\\\\\\\ x M UNrrnD STATES? PATENT OFFIQ WILLIAM E. JERAULD, OF VALTI-IAM, MASSACHUSETTS, ASSIGNOR TO THE AMERICAN STEAMGAGE COMPANY, OF BOSTON, MASSACHUSETTS, A COR- PORATION.
SPECIFICATION forming part of Letters Patent No. 699,532, dated May 6, 1902. Application filed September 28, 1899. Serial No. 731,962. (No model.)
To all whom, t 11m/y concern.-
Beit known that LWILLIAM E. JERAULD, of IValtham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Safety- Valves, of which the following is a specification.
This invention relates to an improvement in safety-valves; and it consists in the novel features of construction and relative arrangement of parts hereinafter fully described in the specification, clearly illustrated in the drawings, and particularly pointed out in the claim.
Reference is to be had to the accompanying one sheet of drawings, forming a part of this application, in which like characters indicate like parts wherever they occur.
Figure 1 represents a vertical sectional view of a safety-valve constructed in accordance with my invention, showing the parts in their normal position. Fig. 2 represents a side elevation. Fig. 3 represents a view similar to Fig. l, showing the lever elevated, the spring compressed, and the valve relieved from the pressure of the spring.
The casing 1 and its parts, the valve 2, the valve-seat 3, the spindle 4, the spring 5, the internal collar 6, the external collar 7, the lever 8, arranged to engage the collar 7 when the lever 8 is elevated, the lugs 9, between which the lever 8 is pivoted, are or may be of any well-known or preferred construction, the same forming no part of my present invention.
2O represents a lever arranged upon the ex; terior of the casing and pivoted by a pintle 2l between lugs 22 on the opposite side of the casing from the lugs 9.
23 represents a link pivoted at one end to the end of the lever 8 and at its other end to the lever 2O near the pintle 2l in such inanner that when the lever 20 is elevated, as in Fig. 3, the lever S is also elevated to relieve the valve from the pressure of the spring 5, the link 23 not only serving to communicate motion from the lever 2() to the lever 8, but also by reason of the position of its pintle 4:0 in relation to the pintle 21 to act as a lock and hold the lever 8 elevated until the lever 2O is again depressed by the operator. When the lever 2O is moved from theposition shown in Fig. l to the position shown in Fig. 2, the pintle is carried bythe plane occupied by a line passing through the pintles 2l and il, so that the tendency of the spring 5 to depress or pull down the lever S is to force the end of the link 23 toward and against the abutment aorded by the lugs 22, in which position the parts will remain, as stated, until the lever 2O is positively depressed in order to break the toggle action of the link and bring the pintle 40 from the position shown inFig. 3 to the position shown in Fig. 1.
Having thus explained the nature of my in`- vention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it is used or all of the modes in which it may be made, what I claim, and desire to secure by Letters Patent, is-"- f Ink a safety-valve, the combination with a valve-spindle lever,- of a hand-lever pivotally secured to the casing, a link connecting the valve-lever and the hand-lever, and an abutment to act as a stop to limit the movement of the link, the parts being so arranged that when the handlever is moved to operate the valve-lever the link will automatically main; tain the valve-lever ini ts changed position. In testimony whereof I have affixed my sig# nature in presence of two witnesses.
