GAGE-COCK.
SPECIPICATIQN forming part of Letters Patent No. 307,294, dated October 28, 1884.
Application filed Ma 25, 1884.
To all whom it may concern.-
Be it known that I, WILLIAM E. GRANGER, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in GageGocks, of which the following is a specification.
This invention relates to improvements in gagecoeks for steam-boilers, the object being to provide an improved valve and valve-spindle for such cocks, whereby the valvechamher is, by the action of passing water and steam, kept free from sediment, and whereby, with a disconnected screw-stem and valvespindle,.the valve is caused to be rotated while it is being opened and shut.
In the drawings forming part of this specification, Figure 2 is a side elevation of a gagecock, showing the body and wheel in section, embodying my'improvements. Fig. l is a side view, and Figs. 3 and 4 are detail views.
In the drawings, a is the body of the gagecock; b, the outlet. at is the packing-nut inclosing the packing y. i is a set-nut. a is the screw-stem. c is the valve, and c is a valve-yoke. The body a is of the usual form, having the screw cl thereon to adapt it to be screwed into a boiler. The packing-nut m is screwed on the outer end of the body, and provides a receptacle for the packing y. The nut m is screw'threaded to receive the screwstem at. The set-nut t' serves to hold the nut at so that it cannot be shaken and-moved from its proper position. A valve-yoke, 0, having a transverse opening through it, is screwed onto the end of the body a,which is adapted to project inside of the boiler, and a valve-seat, z, is made in the body a just back of the outlet 1) as well as at the end of the body, to provide a proper bearing for the valve 6. The screw-stem a is made with a valve, to, thereon, which is adapted to be forced against the seat 2, if desired, when valve 6 is open, and beyond said valve 10 the end of the stem hasa squared extension, o. The form of the valve e and its spindle c is shown in Figs. 2, 3, and 4, the latter being a section on line a: m, Fig. 3. The valve 6 closes against the end of the body a, its spindle extending into the body, as shown, and being open from side to side, forming rib-connections only between the valve proper, e, and the block (No model.)
8, and beyond the latter the spindle extends in bifurcated form, having between its ends an opening or slot having two opposite paral- 161 Walls. A projection, cc, extends beyond the valve 0, to provide a suitable center to be used in grinding the valve or in turning it.
In putting the parts of the gage-cock together, as shown in Fig. 2, the stem n is put in and the valve c is placed, and the yoke c is then screwed on, the latter serving to limit the movement of the valve 6 away from its seat, but permitting the unobstructed flow of water or steam through the cock when valve 6 is opened.
Referring to Fig. 2, it is seen that the squared end 1) of the stem at enters the slot it between the ends of the spindle c of the valve 0. This manner of connecting said parts provides for rotating said valve and spindle when the stem nis'turned by the hand-wheel 0 to-move the valve from its seat and open the cock, there by inoving any sediment that may have collected between the said stem and valve 6. hen the valve is shut,it is forced toward its seat by the pressure in the boiler as fast as the backward movement of the stem at will permit, the valveand spindle turning meanwhile, and dislodging any dirt which may collect in the spindle-chamber, and they continue to turn after valve 0 becomes seated, and until the squared end a of the stem at is drawn out of the sloth, thus enabling the operator to rotate the valve on its seat to dislodge any obstructions between the parts without forcing the valve and injuring the latter or the seat, or both, as is often the case when some hard substance gets lodged there, and the valve is forced against its seat by the screw-power of the stem when the latter and the valve are rigidly connected together. In case valve 6, from any cause, will not close and stop the flow of steam and water,valve to may be forced against the seat a and stop the passage.
The construction ofthe valve-spindle c in such open form as is provided by the said rib-connections between the valve 6 and the block 8 permits the steam and water from the boiler to wash out thoroughly all dirt from the spindle and its chamber in the body each time that the valve is opened.
WVhat I claim as my invention is- 1. In a gage-cock, the body a,having a valveseat at one end, the screw-stem n, having the squared end '0, and the valve e, having aspindle provided with the slot h in its end to receive said end 1; of stem 72, combined and 0p- 3. The combination, with the body a, of the valve 6, having the open spindle 6, provided with the block 8 and slot 71, and the stem n, having the squared end 11, substantially as set 15 erating substantially as set forth. forth. a
2. The combination, With body (1, having external screw-thread, of yoke c, which screws on said body, and Valve e, having stem 6, the valve having its seat in the body a ins de the yoke, and being loosely retained between the 1 seat and yoke, substantially as described.
WILLIAM E. GRANGER.
