PATRICK MCGRATH, OF PLATTSBURG, NEWY YORK.
IMPROVEMENT IN GAUGE-COCKS.
Specilcation forming part of Letters Patent No. 117,907, dated August 8, 1871.
To all whom it lmay concern.:
Be it known that I, PATRICK MGG'RATH, of Pla-ttsburg, in the county of Clinton and State of New York, have invented a nenT and useful Iniproveinent in Gaugeocks; a-nd I do hereby de- Clare that thefollowing is afull and exact description oi' the saine, reterencebeinghad to the accompanying drawing and to the letters of reference marked thereon.
This invention has for its object the production of a gauge-cock which, from its peculiar construction, shall obviate many diiculties incidental to the ordinary forms, and possess marked advantages over them; and consists in certain details of construct-ion, which will be fully described hereinafter.
In the drawing, Figure 1 represents a perspective view of inyiinproved gauge-cock; Fig. 2, a central sectional elevation; and Figs. 3 and 4, views of the valve.
To enable others skilled in the art to make and use my invention, l Will now proceed to describe fully its construction and operation.
' A. represents a metallic cylinder, which is provided With a longitudinal central bore, a., for the reception of the valve-rod I), and also with the smaller steam-passage al, located upon one side oi the longitudinal center line, as shown. rlhis passage a1 is connected at about the center of its length with a discharge-tube, a2, as shown. The
end of the cylinder A is suitably threaded, in order that it may be removably attached to the secured to the boiler, and the other end suitab y torined to receive a Wrench, by which means it is readily attached or detached. B represents the valve, constructed preferably or' a suitable block of metal, quadrangular in form, and having' inclined sides bl b1, as shown. This valve is revolved upon the valve-seat a of the cylinder A for the purpose of covering` or uncovering the opening otA the stea-ni-liassage a by means of the valve-rod b, which extends through the central bore a. of the cylinder, and is provided With a crank, b2, rigidly attached thereto, as shown. G represents. a lever, provided with an opening, c, by means of which it is slipped over the valve-rod B, which lever is further provided, also, upon its short arin, With a short stud, c', which latter, When in place, projects into and closes the outer end of the steani-liiassage al. D represents a collar located upon the valve-rod between the lever C and the crank b1, Which is provided with a socket for the reception of a short spiral spring, d, which rests thereon, and bears against the crank-arm, as shown.
The operation is as follows: The crank-arm is operated in the usual manner to use the cock. By its movement the valve is revolved to cover or uncover, as inay be desired, the inner opening ot' the steanilpassage al, by which ineans steam or Water, as the case may be, is permitted to pass out through the steam-discharge tube a2, or is cut oit therefrom. The outer end of the passage a, it will be observed, is closed by the stud of the lever G. From the peculiar construction herein described it is impossible for obstructions to get between the valve and its seat, and, consequently, the valveis always tight, bein g kept in place not only by thc pressure of the steam, but also by the action of the spiral spring d. By means of this latter, also, the necessary expansion and contraction ot' the metals under the intl uence of the heat are permitted. li' an obstruction shouldreinainprojectingfromthe steampassage as the valve closes, the projecting portion of it will be severed by the sharp edge formed by the inclined sideoi' the valve, and, bein g forced away as the valve revolves, no damage can result from it.
It the steainpassage should become clogged from any cause the obstruction may be .removed by uncovering the outer end of the steam-passage al by withdrawing the stud of the lever C from the outer spring of the passage, this operation being easily permitted by the yielding of the spring d, and by inserting a suitable rod or Wire to remove the Obstruction.
The described gauge-cock is very siniple in its construction, and exceedingly etiective in its operation. li desired, substai'ltiallythe saine construction niay be used for faucets.
Havin g thus fully described iny invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination of a springlever with an independent steam-passage, as described.
2. The combination of the cylinder A, lever C, and spring d, as set forth.
, 3. The gauge-cock described, consisting of the cylinder A, valve B, with rod b and arm b2, lever C, and spring d, constructed and arranged as described.
This specification signed and witnessed this 24th day of June, 1871. PATRICK MOGRATH.
