To all whom it may concern:

Be it known that I, HENRY A. HATFIELD, a citizen of the United States of America, residing at Clarkson, in the county of Gray- 5 son and State of Kentucky, have invented new and useful Improvements in Motors, of which the following is a specification.

This invention relates to motors designed especially for imparting reciprocatory motion to churn dashers, cutting devices and other elements which have' reciprocatory action.

The accompanying drawing shows a perspective view of my improved motor as arranged for use for operating the dasher of a churn.

Ieferring to the drawing, the numeral 1 designates a suitable bed pieceor platform, I to which is secured a rectangular base 2,

triangular supporting standards 3, each composed of'a pair of side rods or bars 4, an intermediate rod or bar 5, said bars being suitably connected at their lower ends to the base 2 and joined at'their upper ends, and a cross bar 6 with bearings thereinuniting and staying the bars at a suitable elevation above the base. The two standards are connected at their up er and lower ends by tie rods 7 andf8, whlc maintain them in fixed relation.

Mounted in bearings cross-bars 8 formed or rovided upon the up er ends ofthe standar sis a main drive sha t 9, which is extended'at its ends beyond said standards and carries at one end a balance or iy wheel 10. The other end of the shaft is bent to form a crank 11 carrying a sliding sleeve 12 adjustably secured thereto by a set screw 13 and carrying a wristl pin 14 threaded for the reception of a nut 15. The shaft 9 may be driven through the medium of any preferred driving mechanism, but is shown in the present instance arranged for operation from a Vdriving shaft 16 journaled in bearings formed at the intersection of the main bars of the standards with the cross bars 6. The shaft 9 carries a pulley 17 connected by a belt 18 with a pulley 19 on the shaft 16, and the latter is provided with an actuating crank`20, whereby it may be driven directly by hand power.` The shaft 16 is further provided with a -crank bend 21 operatively connected by a pitman or connecting rod 22 with a treadle 23\fulcrumed on the rod 8, whereby the operating mechanism may-be slams mitm? from the sides of which rise substantially actuated-bly foot Vpower, desired," or both hand and foot power through the medium of the -said treadle and the crank 20.

rmly clamped in .operative position by a clamping device composed of rods 26 hinged at their lower ends t'o the latforni, and a transverse rod 27 provide with terminal elyps engaging the rods 26, which latter are t eaded at their u per ends for the reception of nuts 28.` he rods 26 engage and confine the churn body in lace, while the rod 27 extends across and c amps the lid to said body. Arran ed on therods 26 above the ends of the ro 27 are coiled springs 29 `which` exert a yielding clamping pressure against the rod 27 and are held 1n position by the nuts 28, whereby the ressure of said s'prings may be varied tp c amp the churn pody and its lid with the desired degree of orce.

The dasher rod 30 is operatively connected by a pitman with the crank of the shaft 9, said pitman being composed of two sections, namely, a rod 31 ivotally engaging the wrist pin 14 and co ed thereon by thenut 15 and a sleeve section 32 `jointed to the lower end of said rod, as shown at 33, and receiving the upper end of the dasher rod 30, to which it is secured byr a set screw 34. By this construction the pitman is adapted for connection with long or short rods, and also through such construction and the construction of the parts 11, 12, and 13 the throw or action of the driving crankmay be varied to vary the stroke ofthe itman and dasher.

It will thus be seen t at the invention provides a'sim le .and effective construction of motor whic may be employed for actuating churn dashers and other reciprocating devices and which is adjustable for connection with long or short operating rods and also to vary the stroke or extent of movement of the operated part as circumstances may require. Having thus described the invention, what I claim is: e

' A motor comprising a basewith standards rising from the opposite sides thereof, intervmediate bars likewise secured to the base and 'grouped at their upper ends with seid 'stndards brace rods at the u per and lower ends l if-'Stile standards, crossars with bearings 5 therein .secured at suitable distances apart to the-standards and said intermedi-ate bars, drive shafts mounted respectively. in' the bearings of the cross-bars, e pulley on each' of said shafts, a belt connecting said pulleys,

the up er shaft.' having a crank-arm, and 1'0 means or driving the lower shaft, substantially as specified. ,v p

In testlmony whereof I hereunto ax my signature invpresence of two Witnesses.
