.Letters Patent No.109,678, dated November 29 1870.

IMPRVEMENT IN PUMPS `The Schedule referred to in these Letters Patent and makingl part of the same.

To all @cham fit may concern Be it known that I, WILLIAM SHEARER, of Atlanta, in the county of Fulton and State of Georgia, have invented a new and improved Pump; and Ido hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had tothe accom pan ying drawing forming part of this specification.

This invention relates to improvements in -`nm'ps, and consists in an arrangement of diaphragins of leatheigludia rubber, or other exible and elastic substance, to. he used in substitution for the pistons, for economizing friction, the arrangement being sneh that no piston or piston-rod packing is needed, and the valves are formed -iu the diaphragms, and of parts thereof, in a simple and inexpensive manner.

Figure lis a vertical'sectional elevation of my hlnproved pump, and

Figure`2 is a vertical sectional elevation ol' a part of the same, the line ofthe section being perpendicular to that of iig. 1.

Similar letters ot' reference indica-te corresllomling' parts.

A is a hollow cylinder, open at both ends, and provided with thedividing-plates B and the passages C U', the latter being formed on the outside, preferably opposite each other, and leading from end to c nd.

Each end of the cylinder has a cap, D, bolted or otherwise attached to it, which has a plate, E, extending across the end of the cylinder, between 'which plat-c and the cap is a water-space, F.

These plates have openings, a li a' Il, coinciding with the passages, and they have cavities, l d', iu the sides, next the cylinder, forming passages under the ends of the cylinder, from the passages G C' to the interior.

`The disks 1S are placed at some-distance. from the ends of the cylinder, and form bearings for the work ing-rod G, passing tbrough'them, and having the leather, India rubber, or other flexible diaphragm H Il' attached toit, one to each end.

Said diaphragms are clamped, at the outer edges, between the cylinder and the plates E of the caps.

These diaphragms are suitably cut to form valves over the openings througlrthe plates E,all opening upward.

The rod G is'worked by a lever, I, arranged in` ,slots or bearings in the cylinder A, between the plates them, and t-heV movement in the other direction forces it out 'and into the upper chamber F, as will be clearly seen by inspection oi' the drawing.

lhe arrangement here shown constitutes a doubleacting pump, but a single diaphragm and working-rod applied to-any ordinary cylinder, and provided with a' valve opening upward, will make a simple, easilyworking, single-aeting pump on the same plan.

The valve should be seated at the center i the diaphragm, the rod' being forked or otherwise suitably arranged.

In this example, screw-plugs N are inserted in the holes passing Athrough the plates B, to provide suftcient bearing-snrtace, but other arrangements of bearings may be employed, as preferred. lhey should not, however, be so tight as to prevent the free passage of air to the spaces in which the diaphragms work 5 or the plates B mayhave air-holes through them.

Ha'vinglthus described my invention,

I claim as new and desire to secure by Letters Patentrihe combination of the cylinder A, caps D, plates E, diaphragms 1I H', and the working-rod, the cylinder being provided with the passages, the plates E with the openings, and the cavities and the'diaphragms with the valves, all substantially as specified.

\Vitnesses: WILLIAM SHEARER.
