Lmm Patent I1in.- 102,171, datednpw'z 19, 1870.

IMPROVEMENT IN CHURN POWER.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

' Beit known that 1:, RUTH N. SMITH, of the city, county and. State of New York, have invented a new and improved Ghurn Power; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those' skilled in the art to make and use the same, reference being had to the accompanying drawing forming part -of this specification, in which drawingy Figure 1 represents a sectional front viewof .this invention. p

Figure 2 lis a transverse vertical section of the same.

Similar letters indicate corresponding parts.

This invention relates to a chur'n power composed of a crankshaft,whicl1 connects, by means of a bifurcated rod and a swivel head, with the dasher-stali,

' saidstai` being guided in a removable bracket, se-

cured to the flame of the churn powerin such a manner that the required reciprocating motion can be imparted to the dasher without creating much friction, and, furthermore, by means of the removable bracket and swivel head, the operation of connecting a churn to or disconnecting it from the power is materially facilitated.

In the drawing-` The letter A designates a frame, made of metal or any other suitable material, and provided with two bearings for the crank-shaft B, which are geared together by cog-wheels a b, with a hand-crank O, so that, by the operation of said hand-crank, a rapid rotary motion can be imparted to the crank-shaft.

lo the clank of this shaft is attached a bifurcated rod, I), the arms of which form the bearings for the gudgeons c of a head, d, which is perforated with a hole to admit the stad' e of the churn-dasher.

A pin, f, which passes transversely through the swivel-head d, and through the dasher-stafi, forms the connection between said head and the staff, and compels the churn-dasher t-o follow the motion of the rod D.

- it can be held in position by a simple pin.

To the cross-bar g of the frame A is secured a bracket, h, which` is perforated with a hole to admit the dasher-staii, and to guide the same in its up and down motion. This bracket is secured to the crossbar g by a screw, which passes through a flange extending frorn the bracket and resting on the cross-bar, or said bracket may be constructed with two flanges, capable of straddling the cross-bar, and, in this case, In either case the bracket his removable, and, if it is desired -to disconnect the churn from the power, the bracket is taken ou", and, by removing the cover ofthe churn, the dasher can be readily brought in such a position that it-s staff can he withdrawn from the swivel-head d, since this head allows of swinging the dasher out to the position required for this operation.

From this description it will b'e readily understood how the dasher-of a churn is to be conncted to my power, and it will be. seen that, by the combined action of the removable bracket h and the swivel-head d,.tixe operation of connecting and disconnecting a churn tothe power is materiallyfacilitated, and that churns of diierent sizes can be readily operated by my po wel'.

It must be remarked that the form of the frame canbe changed, so as to allow of introducing and removing the churn with ease and facility.

What I claim as new, and desire to secure by Letters lPatent, is v The churn and power, consisting of the frame A, the crank-shaft B, the bifurcated rod D, the shaft E, the gudgeons c c, the swivel-head d, the gearing a b, the crank C, the cross-bar g, bracket h, and churn, all combined, arranged, and operating as described.

This speciication signed byl me this 26th day of February, 1870.

RUTH N. SMITH.
