ALLEN BAGLEY, OF YPSILANTI, MICHIGAN.

Letters Patent No. 105,162, dated July 12, 1870.

IMPIROV'EMIEINEI? IN DOBLE-ACTING- FORCE-PUMPS.

The Schedule referred to in these Letters Patent and making part of the same. l

To whom it may concern.-

Be it known that I, ALLEN-Bueller, of Ypsilanti, in the county of Washtenaw and State of Michigan, have invented a new anduseful Improvement in Double-acting Force-Pumps; and I d o declare that the following is a true and accurate description thereot', reference being had to the accompanying drawing and tothe letters of reference. marked thereon and being a part ot' this specification, in which- Figure lis a perspective of the curb and its attachments, and its connection with the pump below.

Figure 2 is a vertical section of the pump.

Figure 3, a perspective view of the lower valve.

Figure 4, a view of the cap on the lower valvestem.

Figure 5 shows the upper valve, stem, and spider.

Figure 6 is the valve-seat for the upper valve.

Like letters indicate like parts in each figure.

The nature of this invention relates to an' improved double-acting force-pump, by means of which a continuous flow of water may be obtained, and which will force water from deep wells with but comparatively little labor; and

It consists ina new and ingenious construction and arrangement of valves, and in a new and novel combination of its various parts.

In the accompanying drawing- A represents two pump-barrels or cylinders, to the top of which is secured, in any convenient manner,

the semicircular neck B, whose internal diameter isv the same as that of the barrels, and from the center of which rises the discharge-pipe G.

D is a ring fitted to the top of each of the barrels, and forms a seat for the valve E, which is provided with a stem, a, the lower ends ofwhich are provided with spider-arms b, whose length is equal to the cross-section of the diameter of the barrels, and which act as guides, to compel the valve to its place in the seat.

ll is a diaphragm, perforated, as shown, and secured to stein d. I

A disk, G, is sleeved on said stem d, and rises and falls, as occasion may require, between the diaphragm Fand the nut h., on the upper end of the stem ll.

H is a yoke, the center of which is secured to the lower end of the stem d, and through or toits ends are secured the outside connecting-rods I, which are bifurcated, as shown in iig. 1, and connected at top to the double crank-shaft J, which receives motioni'roni the crank K, or from any other convenient device.

The pump being in place at the bottom of the well, andthe crank at top in place, with the connections made as herein described, the rotary motion of said crank causes the valves or disks G to alternately rise and-fall; that is, as one of the valve-stems cl has a downward mot-ion, the water ows upward through the perforations in the diaphragm F, raising the disk G, which, until this movement, has covered said perforations. Then, as said valve-stem is given an upward motion, the disk again covers the-perforations in the diaphragm, thereby retaining the water within the barrel. This operation continues, with the continued rotation of the crank, until the barrels are full, when the further operation ot' the crank compels the valves E, alternately, to open and close, and the water is discharged in a continuous stream through the pipe C. I

What I claim as my invention, and desire. to secure by Letters Pat-ent, isy 4 1. Thecombination of `the valve E, provided with stem a and spiders b, and seat D, with the diaphragm F, secured to stem d, having Sleeved upon it the diskvalve G, when the several parts are constructed substantially as described and shown, and arranged to operate as and for the purposes set forth.

2. In combination with the above-named parts, the barrels A, neck B, and discharge-pipe C, the crankshaft J, the connecting-rods I, and the yoke H', when constructed substantially as described and shown, and arranged to operate as and for the purposes set forth.

ALLEN BAGLEY.
