VICTOR GIROUD, OF NEW YORK, N. Y.

IMPROVEMENT IN STEAM-GAGE COCKS.

Specification forming part of Letters Patent No. 49,623, dated August 29, 1865.

To all whom it may concern:

Be it known that I, Vrc'roa GIaoUD, ofthe city, county, and State of New York, have invented anew and useful Improvement in Cocks for lVater and Steam Gra ges and for other Purposes; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to thel accompanying drawings, forming a partot this specification, in which- Figure 1 isa longitudinal vertical section of the lower socket and cool; of a glass Watergage constructed according to my invention. Fig. 2 is a vertical transverse section in the plane indicated by the line o: x in Fig. l.

Similar letters of reference indicate corresponding parts in both igures.

This invention consists in a novel arrangement ot' passages in the plugl or spigot ot a cock, whereby, in its application to a water or pressure gage, it is made to serve the purpose ot' forming and closing the communication between the boiler or other vessel and the gage, and also provide for blowing' out the socket or tube ot' the same, thereby obviatin g the necessity ot' a separate cock for blowing out, and is made to blow out the water or steam in such direction as will not be productive of injury to the engineer or fireman, or to surrounding articles or structures.

In order to instruct others skilled in the art to construct and use my invention, I will proeeed to describe it with reference to the drawings and letters thereon.

The ordinary construction ot' a cock for a water or pressure gage is provided with a plug, A, which is furnished with the two ways a and a, the former of which runs through the plug in a direction perpendicular to its axis. This way forms the through-communication, when open, with the boiler or vessel to which it is attached andthe gage. The second way,

a, commences in the same line of rotation, and the center of its apertureis at au angle ofniuety degrees to the way c, and runs obliquely toward the center ot' rotation ofthe plug, and alters its course by a bend, the latter part ot' which runs parallel and concentric with the linear center of the plug, and opens outward to the air upon the side ofthe gage through the plug A. This arrangement of ways prevents thewater, steam, or sediment which may be blown out from comingin contact with the person attending to it., as it would it it were blown out forward of the gage, or at its lower part, in a vertical descending direction.

The plug A is represented in a position for the passage a' to form a communication betweeuthe boiler or other vessel and the tube ofthe gage. The way a is broughtinto communication with the glass or tube ot' the gage and the atmosphere by turning the plug A the distance ot' a quarter-circle from the position above described tothe right, bringing the handle or lever ot' the plug into an upright position 5 and to make a communication with the boiler or other vessel and the atmosphere the plug A must occupy a position directly opposite to that last described. This description relates exclusively to the bottom cock ot` a water-gage. The same arrangement will apply to the upper cock, excepting the motions ofthe plug, which will be reversed orin a contrary direction.

This cock is not conlined in its uses simply to water-gages upon steam-boilers, but may be applied to any water or steam fixture where such an arrangement is necessary.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

The arrangement of the way a, as herein described, in relation to the way a in the plug ot' the cock, for the purpose herein set forth.

V. GIROUD.
