AM PHOM 'LITHUGRAPH/G :64 M X (usual/15S muss) UNITED STATES PATENT UFFICE.
AARON L. HATFIELD, OF CLYDE, OHIO.
IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. 143,759, dated October 21, 1873 application filed July 25, 18 73.
To all whom it may concern:
Be it kllOW'll that I, AARON L. 'HAT FIELD, of Olyde, Ohio, have invented certain-Improvements in Pumps. The nature of my invention Consists in certain improvements in double-action force or lift pumps, which the following specification.
describes.
In the accompanying drawings, A A, Figure 1, is the stock. B B are two plungers; (l-O,
,rods connecting the plungers and levers or guides D D, Figs. 1 and 2., E E are short rods or links connecting guides to pitmen F F. Said pitmen constitute part of shaft I, which is also supplied with a crank or pulley.
I am aware that pumps having two or more plungers have been used before.
My improvement is in the mode of connect ing and operating the plungers.
Most double-action pumps require one or more extra stocks attached, and operated by a lever, push, and pull, alternately, which is exceedingly tiresome. Others, having but one stock, require the upper plunger to have a hollow rod or pipe, through which the rod of the lower plunger passes to make connection with cam, or otherwise, on crank-shaft, making it complicated, and-too expensive for general use. To obviate these objections I have-at:
tached to the lower end of rods 0 O pieces i i, which need be but short for the upper plunger, but spread and fastened to the plunger on opposite sides by screw and nut. The rod 'for lower plunger requires the pieces or guidesi '5 to spread and run parallel the distance of'the stroke of the plunger, so as to pass free, and not bind, through corresponding holes in the upper plunger, and fastened to the lower plunger with screw and nut. The upper ends of rods 0 O are hung on two bolts, 0 c, which are fixed permanently on guides l) D. Guides D D play 011 pin 0, and govern the motion of rods 0 O nearly in parallel lines, thus preventing cramping and friction. The lower ends of AARON L, HATFIELD.
