JOHN S. STUART, 0mm YORK, N. YQ,
{l M'PR'ovEM ENT l fN' PUM Psi Specification forming part of Letters Patent N 0. 199,596, dated January 22, 1878; application filed July 25, 1877.
To all whom it may concern:
Be it known that I, JOHN J. STUART, of the city, county, and State of New York, have invented a new and useful Improvement in Pumps, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, forming part thereof, in which-- t Figure 1 represents a front view of a pump containing my improvement. Fig. 2 is a ver tical cross-section thereof. Fig. 3 is a vertical section of a portion of the movable barrel and suction-pipe.
- ted within said barrel or barrels, and an airchamber, which is connected to the suction pipe or pipes, the air-chamber and said pipe orpipes being each provided with a suitable valve, so that when a reciprocating motion is imparted to the pump barrel or barrels, and the suction pipe or pipes are connected to a liquid-supply source, the liquid is drawn into said pipe or pipes and ejected therefrom into the air-chamber, whence it may be conducted to any desired spot; also, in the combination of one or more movable pump-barrels, closed at the upper end, with an air-chamber and one or more suction-pipes fitted within said barrel or barrels, and having an inwardly-projecting flange on the upper edge thereof, for
the attachment of a packing-ring of leather or other suitable material, so that when this ring is put in place a very close joint is produced between the suction pipe or pipes and said pump barrel or barrels, as hereinafter more fully described.
In the drawing, the letter A designates the movable barrel. B is the stationary suctionpipe, and G is the air-chamber, of my pump, a single barrel and pipe being in the present example used, but which may be duplicated, if desired. I
The barrel A is closed at its upper end, and connected by means of a rod, D, to a handlever, E, which has its fulcrum on a stud, a,
projecting fiom a frame, F, which serves to support the parts of my pump, so that a reciprocating motion can be given to the barrel. The suction-pipe B isfitted in the barrel A, and it is secured to the frame by means of straps G, or in any other suita le way.
The air-chamber (3 is connected to the suction-pipe B at the side of said pipe by means of a branch pipe, H, which is curved at the end where it is secured to the air-chamber, so as to permit of bringing the latter in a vertical position.
In the lower'part of the air-chamber O is arranged a clack-valve, b, and in the suction;
pipe B is placed a similar valve, 0, the latter being situated below the point where the branch pipe H is secured to the suction-pipe, and both said valves 12 and 0 being arranged to open upward. Thus, when the barrel A is moved upward the valve 0 is opened and the valve 'b is closed, and vice versa, so that by the upward movement of said barrel the suction-pipe B is filled, while by the downward movement thereof the contents of said pipe are discharged into the air-chamber G.
On the upper end of the suction-pipe B is formed or secured a flange, d, projecting inward, (best seen in Fig. 3,) and to this flange is attached a packing-ring, e, of leather or other suitable material, a metallic ring, f, of equal width to the flange d, or nearly so, being placed above said packing-ring e, and being secured to the flange by means of screws g, or in any other suitable way. The packing-ring e is made of such width that it projects be yond the outer edge of the suction-pipe B; and hence, if the outer edge of said packing-ring is bent upward, it is pressed against the inner surface of the barrelA at all times by the action of the liquid, and especially during the downward movement of the barrel A, and hence the liquid is effectually prevented from escaping.
What I claim as new, and desire to secureby Letters Patent, is-
1. The combination, in a pump, of a movablepump-barrel, closed at the upper end, and a stationary suction-pipe fitted within said pump-barrel, and an air-chamber connected with the suction-pipe, the suction-pipe and air-chamber being provided with suitable valves, and the whole adapted to operate sub.- stantially as described.
2. In combination With the movable pumpbarrel, the stationary suction-pipe, provided with an inwardly-projecting flange on its upper edge, to which is attacheda packing-ring.
of leather or other snitable material, substantially as specified.
In testimony that I claim the foregoing I have hereunto set my hand and seal this 7th day of July; 1877.
