DEVICE FOR CUTTING OFF THE FLOW OF WATER THROUGH FLEXIBLE PIPES,
SPECIFICATION forming part Of Letters Patent N0. 653,629, dated July 10, 1900.
Application filed October 17, 1899. Serial No. 733,885. (No model.)
To all whom it rncty concern:
Be it known that I, GEORGE SCHNEIDER, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Devices for Cutting Off the Flow of Water Through Flexible Pipes, of which the following is a specification.
This invention relates to a device for checking or cutting off the flow of water or other liquid through a flexible hose, and the invention is especially adapted for use on long lines of hose, such as fire-hose.
The object of the invention is to produce a device which may be readily applied to a line of fire-hose while the same is full of water under pressure to cut ofi the flow of water therethrough, and thereby obviate the necessity, which frequently arises, of sending back to the source of supply, as to the engine or pump, and thus save valuable time in cases of emergency.
It frequently happens at fires that a section of pipe bursts, and the present invention is designed to be applied to the hose between the source of supply and the point of rupture and at the place of application to temporarily out 01f the flow of water during the operation of removing the ruptured section and the insertion of a new section.
With this object in view the invention consists in the arrangement and combination of parts,-as hereinafter shown and described.
In the drawings, Figure 1 is a longitudinal sectional view through my improved device and also through a section of flexible-hose, the device being illustrated in the cut-off position. Fig. 2 is a side view of the device and shows the operating-arm in the released position; and Fig. 3 is an end view of the device in the cut-off-position as in Fig. 1, except that in this view the flexible hose is omitted.
Referring to the drawings by letters, A designates the flexible hose, and 13 the shell of the cut-off device.
The cut-01f device comprises a shell of two sections orhalves c 0, connected together at one side by a hinge d. The ends of the two sections are provided with semicircular openings which when brought together form circular holes c,through which the hose is passed. The object of thus making the device in halves is to enable it to be opened so as to be placed about the hose, the latter taking in the semicircular openings in one half, and then the other half 0 may be swung over the top of the hose, and thus confine the latter in the circular openings. The upper section 0 is provided in its top withan opening f, and a stoplug g projects upward from the top. This section 0 is also provided with a pivot-pin or shaft h, extending across, which carries a cutoff arm 7;. This arm 4 it will be seen, is movably supported between the opposite interior walls of the upper'section c, and at the extreme end said arm t'carries a roller j, extending across. The upper section 0 of the shell carries on its exterior side a swinging hooklatch it, which is pivoted at Z to said section, and said latch 70 projects down and its hook end is adapted to take under a lug 'm on the lower section 0', and thus lock the two shellsections cc together. Obviously such a latch may be on the rear side as well as the front. The lower section 0 is provided with a second lug n, and a turn-button o is pivoted to the side between said lugs m and n, and when the latch is is in the locked position, as seen in Fig. 2, the turn-button may be shifted to bind against said latch 70 and the lug n, and thereby prevent the latch from accidentally becoming disengaged from the lug m. The upper end of the cut-off arm 11 projects up through the top opening f, and said arm is preferably bent and its end is formed into a socket 19, into which an operating-lever q is inserted. The lever q thus is at an angle with respect to the cut-off arm 2'. When in the cut-off position, (see Figs. 1 and 3,) the socket p rests on theistop-lu g g, and the weight of the operating-lever will hold the same in this position. Projecting laterally from one end and on the exterior of one side of the lower section 0 is a flange r in the same plane as the bottom, which serves to overcome the tendency of the shell to tilt up when the lever q is turned in the inclined or operated posi tion, as in Fig. 1.
It is believed that the operation is obvious.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combination of a metal shell comprising two sections which are hinged together at their sides one upon the other, said sections provided in each end with an opening; a hook-latch on one section which engages a lug on the other section to secure the two sections when closed together; a cut-off arm pivoted within one of said sections and adapted to be swung into the other section and a flange projecting from one end of the lower section to prevent the shell from tilting when the cutoif arm is operated.
2. The combination of a metal shell comprising an upper and lower section which are hinged together at their sides one upon the other, said sections provided in each end with an opening; a cut-01f arm pivoted within said upper section and adapted to be swung into the lower section; a swinging hook-latch pivoted to said upper section and which projects down and takes under a lug, m, on the lower section a second lug, n, on said lower section; a turn-button pivoted on said lower section between said two lugs and when shifted bindin g against both said swinging hook-latch and said lug, n, as and for the purpose set forth.
In testimony whereof I affix my signature in the presence of two witnesses.
