`Nrrnn STATES IMPROVEMENT IN CONICAL STOP-CQCKS.
Specification forming part of Letters Patent No. 124,959, dated March 26, 1872.
Specification describing a new and useful Im-i provement in Gonical Stop-Cocks, invented by J. EVANS JONES, of Tidioute, in the county of XVarren and State of Pennsylvania.
Figure l represents a sectional side view of the stop-cock and shell. Fig. 2 is an end view thereof.
Similar letters of reference indicate corresp ondin g parts.
This invention has for its object to permit the removal of truncated conical plugs or stopcocks from their shells for inspection or repair Without endangeringits fastening devices. The invention consists in causing the small end of the plug to protrude through the shell, and in providing it with a projecting button, that may be struck by a hammer or mallet whenever it is necessary to loosen the plug for removal.
The ordinary stop-cocks also protrude through the shell, but arevheld in place by nuts applied to their small ends. When, after removal of the nut, a plug is to be loosened in its seat, it must be hammered at the small end. Thereby the plug is frequently very much injured, and often entirely ruined, the screw-threads being destroyed or battered. This injury is prevented by my arrangement of projecting plug, which has no screw-thread shell by screws a. The smaller end of the plug A projects through the shell, and has a projecting knob or button, b, of hemispherical or equivalent forms. Whenever the plug is to be loosened for removal,it can, afterthe screws a are taken oit', be struck on the button b Without injury.
I do not claim the cap O and screws a, as the same have already been used on plugs Whose small ends did not protrude through the shell; but
Having thus described my invention, I claim as new and desire to secure by Letters PatentrIhe plug A provided with' the projecting button 11, and made to protrude with its small end through the shell B, being held to its place at the large end, as specified.
