IMPROVEMENT IN PUMPVS.
Specification forming part of Letters Patent No. 172,265, dated January 18, 1876 application filed November 11, 1875.
ot' cylinder, in combination with half-ear hangers and a removable lug, for controlling the position ofthe valve; second, in a check-valve provided with forked lifters, in combination with a rod extending through the cylinder for operating the valve to clean it; third, in a Scraper, which tits round the check-valve, incombination with rods for operating it from the outside of cylinder, so as to clean the valve; fourth, in the combination of a suctionvalve with slotted lugs and rod, for operating the valve, so as to clean it, and with a lug for controlling the position of the valve.
In the drawings, Figure 1 is a side elevation, showing the exterior of my improvement. Fig. 2 is a longitudinal section of a pump provided With my improvement; Fig. 3, an enlarged inside view of the check-valve and attachments; Fig. 4, an enlarged inside view of the piston-valve and attachments. Fig. 5 shows the means for engaging the rod with slotted lugs on the suction-valve.
A represents the pump-cylinder, which is v provided with man-holes at its ends, which are closed by Clamps and covers C B, in the ordinary manner. M represents the head of the pump, to which the check-valve L is attached. This valve is provided with a ground hinge, water-tight against the head, and bearing against half-ears b, projecting out from the head M, and it is held in place by a removable dog, r, fastened by a screw put through it and into the said head.
To remove the valve the screw is to be p taken out to remove the dog, after which the The top part of the valve is provided with a forked lifter, c, Fig. 3, that a notched. rod, E, may be turned, so as to lock into the lifter and pull the valve open. Surrounding the sides and bottom of this valve is a closely-titting scraper,` N, which is rigidly fastened to two rods, F, put through the head M.
By drawing out and pushing in on the rods F the valve will have removed from it any aecumulation thereon.
The induction-pipe K communicates with the valve L, and, in practice, a flexible pipe is to be attached to it, and extended into the vault or the place to be cleaned. The seat It of the piston is attached to a scoop-shaped Conductor, R, for guiding the material elevated into the piston. The valve P is hinged in the same manner and by similar means as the valve L, and above it is placed a dog, r, to prevent it from rising too high to enable the valve to be removed through aman-hole above, in the same manner as the valve L is removed. '.Io the face of the valve P is attached a slotted lug, t, in which a rod, D, may be locked, to open and close-the valve for cleaning it, and for allowing material to be turned back into a vault, if an overload be taken up.
The pump, in use, is to be mounted on wheels, and a pipe is to be attached toit at m for conveying the material elevated into a portable tank or box for removal.
The rods D E are to be locked into the lifter c and lug t by being pushed into the cylinder A, with the dat sides of their blades in vertical position, and then turned one-fourth round.`
The releasing is done by a reverse movement.
For the convenience of using the rod D, I
employ two piston-rods, Gr, secured to the piston R at n n, Fig. 4.
I claim and desire to secure by Letters Patent- 1. The valve L, with its hinge fitting the head M water-tight, in combination with halfears b b and removable dog r, as and for the purpose set forth.
2. The valve L provided with forked lifter 4. The combination of the valve P, slotted c, in combination with the rod E, as specified. lug t t, and rod D7 and dog 1, substantially as 3. The scraper N, surrounding the edges and for the purpose set forth.
