CHURN-MOTOR.

SPECIFICATION forming part f Letters Patent No. 290,799, dated December 25, 18E3.

Application inea Juli@ 15, 1883. (No man.)

To @ZZ zzz/"wm it may concern:

Be it known that I, ORsANUs E. PERRY, a citizen of the United States, residing at Vhitehall, in the county of Muskegon and State of Michigan, have invented a new and useful Churn-Motor, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to motors for that io class of churns which are provided with vertically-reciprocating dashcrs, and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective view. Fig, 2 isa vertical transverse sectional view. Fig. 3 is a horizontal sectional view on the linex x in Fig. 2,

2o and Fig. 41s a horizontal sectional view on the line y y in Fig. 2.

The same letters refer to the saine parts in all the gures.

A in the drawings designates the rectangu\ lar base-frame, the sides of which have grooves B B in their inner sides, to accommodate a longitudinally-sliding iioor or plate, C, which `supports the churn-body D. The sides of frame A have uprights E E, strengthened by 3o suitable braces, F F, and provided with bearings for a pair of transverse thumb-screws, G G, carrying attheir inner ends swiveled clamps H H, adapted to clamp and hold the churnbody during operation. The upper ends of the uprights E E are connected by a cross bar or brace, I.

Journaled transversely in the uprights E E, near the upper ends of the same, is a crankshaft, J, having a iiy-wheel, K. One end of 4o the shaft J extends through one ofthe uprights provided with a crank, P, by which it maybe operated.

Q is a brace, having forked endsR, that straddle the uprights E E,With which the said brace is adjustably connected by thumb-screws 5o S S, working in vertical slots T in the said uprights. The brace Q is provided with upwardly-projecting vertical guides U U, capa ble of slidingvertically in grooves V V in the inner sides of the -uprights E, which said grooves serve to hold the guides Ufirm and steady. The brace Q has a vertical perforation, WV, access to which may be had through a hinged clamp, X, at the front side of said brace, and the underv side of the latter has a cup-shaped recess or concavity, Y.

Z is a cross-head sliding vertically between the uprights E E, and having its ends grooved, as at A', to enga-ge 'the guides U. The said cross-head is connected by a pitman, B, with the crank upon the main shaft J. The dasherstaff C is connected detachably with the crosshead Z, and passes through the perforation YV in brace Q into the churn.

In operation the churn is placed upon the sliding floor, and moved under the brace Q, the clamp X of which may be opened to admit the dasher-sta'ff into the opening NV. The dasher-staff is then connected with thecrosshead, and the brace Q,with its attachments, is then lowered until the cup-shaped recess Y in its under side holds the cover firmly upon the churn. The churn-body is held securely during operation by the thumb-screws with their swiveled clamps. XVhen the churning has been nished, the brace Q,with its attachments, is raised, and the churn may then be readily removed.

I clailn as my invention and desire to secure by Letters Patent of the United States- 1. In a churnmotor, the combination of a base-frame, a pair of uprights, a cross-brace vertically adjustable between thesaid uprights and having a cup-shaped recess in its under side adapted to inclose the churn-cover, and provided with upwardly-projecting guides sliding in grooves in the inner sides of the uprights, a vertically-sliding cross-head having grooved ends engaging the said guides, a pitman connecting the said cross-head with a crank-shaft, and mechanism for operating the latter, substantially as set forth.

2. The combination, in a churn-motor, of the rectangular base-frame, the floor sliding longitudinally in the same, 'the uprights,

thumb-screws working in the latter and hav-A ing swiveled clamps, the vertically-adjustable brace having hinged clamp in front, cup- IOO shaped recess in its under side7 and averti'cal upwardly from the said brace and sliding in perforation, guides projecting upwardly from said brace, a vertically-slidin g cross-head having grooved ends engaging said guides, the pitman, crankshaft, and operating mechanism, all arranged and operating substantially as set forth.

3. The combination of the nprights having vertical slots, and provided with vertical grooves in their inner sides7 the brace having forked ends that straddle said nprights, and provided with binding screws working through the vertical slots7 guides projecting the grooves in the inner sides of the uprights, a cross-head having grooved ends engaging the said guides7 and mechanism for operating the said cross-head, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiiXed 'my signature in presence of two witnesses.

ORSANUS E. PERRY.
