NFETERS. PHOTO-U-THOGRAFHER, WASHINGTON. D C4 STATES PATENT FIRE-PLUG.
SPECIFICATION forming part of Letters Patent No. 236,290, dated January 4, 1881.
Application filed October 11,` 1880. (No model.)
T o all whom it may concern: f
Be it known that I, PETER WHITE, of St. Louis, Missouri, have made a new and useful Improvement in Fire-Plugs, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part ot' this specification, in which- Figure l is an elevation of the improved plug; Fig. 2, a vertical section; Fig. 3, a vertical section of the upper end of the plug; Fig. 4, a vertical section of the lower end of the plug; Fig. 5, a vertical section of the upper end ot' the plug, showing the valve-stem as when the valve is open; Fig. 6, a vertical section of the lower end of the plug, showing the valve as when opening; Figs. 7, S details, being sectional views of that portion of the plug immediately connected with the waste-valve, and Fig. 9 a horizontal section taken on the line a: of Fig. 3.
The same letters denote the same parts.
In the present plug the valve opens against the water-pressure. and the waste is discharged through the valve-stem into achamber in the bottom of the plug, and thence out. l
In the drawings, A represents the improved plug, having the inlet B and outlet or outn lets C.
The valve D is in the form of' a cup-leather. When closed, as seen in Figs. 2, 4, the valve is just wit-hin the lower end of the cylinder a; but in opening the valve it is moved downward into a chamber, a, larger in diameter than the cylinder a, as shown in Fig. 6. The valve is attached to the stemv E. It is supported from the upper side-by means of the plate or washer c; and to enable the water, as the valve is opened, to pass the ange d of the valve, a nut, F, having the tlangef, is attached to the valve-stem beneath the valve. This acts lto spread the inliowing stream and to deliect it, in an annular form, to the outer side of the valve-Harige d, and to prevent the latter from being iattened against the shell of the plug. When theivalve is closed, however, the water pressing between the nut-liange fand the cup-leather causes the valve to become perfectly tight. The valve is operated by means ot' the screw G, which engages in a socket, E', that is `upon the upper end of thel valvefstem E.
To prevent the valve and stemfrom rotating, the socket E is furnished with ribs e' e', which movein grooves hh, that are in a pendant, H. The latter is made part ot1 or is attached to the shell ot' the plug. The rotary movement ot' the screw Gr thus causes the valve to move up and down in the plug.
The stern E extends beneath the valve, the lower end of the stem and the extension E2 being hollow, forming a chamber, I, within the stem, the inlet or inlets i c' to which are just above the plate c, and the outlets at t t. The extension E2 works in a chamber, J, at the bottom ot the plug. g
To prevent the Water from chamber a' down past the end of the extension E2, the latter is furnished with a cupleather, K, arranged as shown, and above the outlets i i.
L represents another valve, (a cup-1eather,) attached to the stem l, and working within the extension E2.
The operation of this portion of the improve ment is as follows: When the valve is opened the lower end of the stem l encounters the bottom of the plug, and the valve L is thereby moved in the extension E2 to above the outlets yi i', and to cut ott the escape of water through the valve-stein; but when the valve is opened the valve L, being forced byfthe weight of the water above it, drops below the outlets z" i'. The water then ows from the cylinder a through the stem into the chamber J, and thence is discharged through the outlet j. The two positions ofthe valveL are shown more distinctly in Figs. 7 and 8.
I claim- .1. The combination ofthe cylinder a, valve D, stem E E2, having the chamber I and passages t' i', chamber J, valves K L, and stem Z, substantially as described.
2. The combination of the chamber J, hav-.
stantially as described.
4. The combination, in a lire-plug, of the cylinder a, chamber a', larger in 'diameter passing from the IOC than the said cylinder, nut F, and the cup- 6. The combination of the cylinder a, valve leather valve D` said valve opening against D, stem E, socket E', having the ribs e e, 1o the pressure and into the chamber a', substfinpendant'J H, having the grooves h h, and the tially as described. screw G, substantially :1s described.
5. The combination ofthe cylinder a, valves PETER WHITE. D K, stem E E2, having; the. chamber l and Vitnesses: passagesz' i, and the chamber J, having the C. D. MOODY, outlet j, substantially as described. CHARLES PICKLES.
