SUCTION-PIPE MOUTHPIECE.
Specification of Letters Patent.
Patented Jan. 19, 1909.
Application filed January 20, 1908. Serial No. 411,680.
To all whom "it may concern:
Be it known that I, JOHN MARKMAN, citizen of the United States, residing at Gladstone, in the county of Henderson and State of Illinois, have invented certain new and useful Improvements in Suction-Pipe Mouthpieces, of which the following is a specification.
This invention is a mouth-piece for the suction pipe of excavators or sand pumps, and has for its object to provide an improved device of the kind, having particular advantages with respect to the slide and check valves in the mouth-piece or nozzle.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a side view of the mouth-piece. Fig. 2 is a central longitudinal section. Figs. 3 and at are elevations of opposite sides of a valve wedge and seat in which the check valve is mounted. Fig. 5 is a plan of the slide valve at the mouth.
Referring specifically to the drawings, 7 indicates the nozzle which is connected to the suction pipe 6. This nozzle is enlarged or flared at the mouth as indicated, and the mouth is provided with a slide valve 8 which is slidable in a frame 9 fixed to the mouth of the pipe, the frame being built up to form guides in which the valve can slide. The valve is operated by means of a lever 9 connected to the rear end of the valve and fulcrumed at 10 to brackets on the side of the mouth piece. The lever is operated by a rod 11 which may be extended to the barge or dredge. By the means shown the valve 8 may he slid in or out to vary the size of the mouth of the pipe. The pipe contains a check valve so constructed or mounted that it can be readily removed at any time, in case of choking or for repairs. This check valve is contained in a casing consisting of a box 12 and a front plate 13, which casing is set in the pipe above the mouth thereof, the parts of the casing being bolted together and bolted or riveted to the pipe sections, having projecting rings or collars 1% for the latter purpose. The casing is open at the top, and the recess within the same is wedgeshaped or tapered, with the wider part at the top. The flap valve 15 is mounted in a depression or seat 16 in a wedge shaped valve plate 17 which is of proper size and shape to fit within the casing above described. The upper end of the valve plate 17 projects above or beyond the casing and has a perforated lug 18 which receives the arm 19 of a lever 20 which is fulcrumed at 21 on top of the nozzle. The lever is operated by a rope 22 connected to the upper end thereof.
It will be seen that by means of the lever 20 the wedge shaped valve plate and valve mounted therein can be readily lifted from the casing containing the same, so that the valve can be removed when necessary for any purpose. \Vhen in place, the check valve operates in the usual manner to allow sand or other material to pass up through the pipe, but closes when the pump stops, to prevent back flow through the pipe. The back of the casing 12, it will be understood, is provided with an opening corresponding to the opening in the valve plate, and the front or top plate 13 of the casing has an opening of sufficient size to allow the valve to swing open therethrough. Both valves can be taken out without removing any bolts or the like, which is advantageous in devices of this kind where the valves are very apt to become clogged in consequence of the nature of the material operated on.
I claim:
1. A suction pipe mouth-piece having a guide frame fora valve at the mouth thereof, and a valve plate slidable in and out in the guide frame, to vary the size of the mouth.
2. A suction pipe mouth-piece having a guide frame extending around the mouth thereof, said frame being open at one side, a valve plate extending through said open side and movable in and out in the frame to vary the size of the mouth, and an operating lever fulcrumed on the mouth-piece and connected to the valve plate.
3. A suction pipe mouth-piece having a tapered valve plate slidable in and out through an opening in the side thereof and across the bore of the mouth-piece, the valve plate having a valve-seat therein and also having a perforated lug at the top, a check valve mounted on the plate, and a bent lever fulcrumed on the mouth-piece and having an arm extending through said perforation to operate the plate.
In testimony whereof I aflix my signature, in presence of two witnesses.
JOHN MARKMAN.
