JOHN BEAN, OF HUDSON, MICHIGAN.

IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 52,660, dated February :5.0, 1866.

To all whom it may concern:

Beit known that I, JOHN BEAN, of Hudson, in the State of Michigan, have invented certain new and useful Improvements in Pumps; and I hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature ot' my invention consists ot' certain mechanical devices in the construction of a pump, by which it is made to throw out a continuous stream of water.

To enable others skilled in the art to make and use 1n yinvention, I will proceed to describe its construction and operation, reference being made to the accompanying drawings.

Figure l is a vertical section of my pump. Figs. 2 and 3 exhibit plan views of two sections of the valve-plates. Fig. 4 is a plan view of the chamber in which the valve-plates operate. Fig. 5 is a plan view of the shaft to which the upper valve-plate is soldered.

The letter A, Fig. l, represents the pumpstock, the bore of which is quadrangular and graduallydiminishing in size from its point of junction with the valve chamber B until it reaches its curved end, from which the water is discharged.

The chamber B describes a circle, and is formed of metal or other suitable material, and rests at one edge on the plate G, and coniined in position by the plate D,the two plates being held together near their lower end by screws e c.

The plate D is hinged to the base of the pump-stock, so that by removing the screws that conne it to C it can be raised up and the valves repaired.

F represents the upper and G the lower valve-plate, said plates consisting of two wings each, united at an angle of about thirty degrees, and havin g the valves near the ends of the wings. The two plates are covered with leather on their upper side, which, being cut through on three sides, forms a ap -valve, I, which rises or falls according as the pressure of the water may be either upward or downward.

The inner ends of the leather covering on plate G are hinged to the axle 7L, thus enabling the plate G to play freely.

The upper plate, F, is soldered to the shaft a, Fig. 5, the shaft a having a socket in the end, which receives 'a pivot, t, on the upper end of It.

It will be observed that when the two plates F and G are in position the wings of F Will be at an ascending and the wings of G at a descending angle.

H represents a wedge shaped block, the thick end of which penetrates ashort distance into the pump-stock, while the lower end descends near to plate F. H is cased on two op posite sides with sheet-irons S, the lower ends of the sheets being at their center long enough to penetrate the leather covering of plate F and there riveted.

It will be seen that the leather coverings on block H extend farther into the bore of the pump than the block H does, so that as H is moved to the right or left, in consequence or the motion imparted toV it by plate F, the alternate ends of the projecting leather will press against the interior ot' the pump, leaving an open space on the opposite side for lthe water to ascend in the pump-bore when forced by the action of the plate F.

K represents an arm fastened to the pump and extending at right angles from it. There are two of these arms at opposite sides of the pump, which answer as bearings to the rod V, this rod being formed into a crank at each end, placed at right angles to each other. The two cranks give motion to the rods m and P, which hook into the bars o, respectively, (see dotted lines, Fig. 1,) the bars o bei-ng litted one on the projecting end of axle 71. and the other on the end of shaft a.

In operating my machine it will be seen that the alternate wings ot the plates F and G will, under the action ot the rods P and m, approach each other and then recede. As they approach each other the compression of the water between the wings will close the valve in G and open the valve in F. As the win g ot' F rises the Water between it and the block H will again be compressed and force its way into the opening between the block H and the pump. This operation is performed l G with thewedge-shaped block H, the rods m alternately by the wings on the opposite sides and n, the arms K, and the bars 0, the whole 0f plates F land Gr, thus producing a continul constructed and arranged as and for the purous stream of water from the spout of `the pose herein set forth.

pump. Having thus described my invention, what I JOHN BEAN' claim, and desire to secure by Letters Patent, Witnesses:

The combina-tion of the valve-plates F and i CHARLES E. THOMPSON.
