MECHANISM FOR OPERATING CHURN-DASHERS.

SPECIFICATION forming part of Letters Patent No. 359,1L5, dated March 8,1887.

Application filed November 11, 1886. Serial No. 218,594. (No model.)

To aZZ whom it may concern:

Be it known that l, J AMES M. FLAoK, a citizen of the United States, residing at Sharon, in the county of Cleveland and State of North Carolina, have invented new and useful Improvements in Mechanism for Operating Ohurn-Dashers, of which the following is a specification.

This invention has for its object to provide IO novel and simple mechanism for imparting a rotary reciprocating to-and-fro motion to the dasher of a churn; and to such end the invention consists in the features of construction and combination of devices hereinafter de- 1 5, scribed and claimed, reference being made to the accompanying drawings, in which- Figure 1 is a perspective view of my improved mechanism in connection with a churn; Fig. 2, a vertical central sectional view of the same, and Fig. 3 a detail plan view of the cross-head on the operatinglever.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the 2 5 drawings, where- The numeral 1 indicates a supporting-base to which is secured a standard, 2, to the upper end of which is mortised the inner end of a bracket-arm, 3, while to the extreme upper 20 end is mortised asimilarbracket-arm, 4, these arms projecting horizontally at right angles to the standard and parallel to each other. The standard between the arms is formedinto a journal, 4*, which is a circle in cross-section,

5 and on this journal of the standard is loosely mounted a horizontal lever, 5, having a handle, 6, and a circular orifice through which the journal passes, thereby permitting the lever to be oscillated in a horizontal plane on the standard between the upper and lower bracketarms. The inner end of the lever is provided with a cross head, 7, secured midway of its length to the lever and provided at its top and bottom edges, at opposite ends,with the bevels or inclines 8, whereby one end of the lever is higher than the other end, as clearly shown in Fig. 1, which construction is for a purpose hereinafter explained.

A circular shaft, 9, having a journal, 10, at

50 each end, is located in avertical plane between the outer ends of the bracketarms, the respective journals of said shaft being loosely located in circular orifices in the outer ends of said bracket-arms. To the upper and lower portions of the shaft 9 are respectively secured one end of straps 11, the said straps being partially wound around the shaft in reverse or opposite directions, and the uppermost strap is carried to and connected with the highest end, 12, of the cross-head, while the other strap is carried to and connected with the lowest end, 13, of the cross-head. Thus it will be seen that by the upper and lower beveled edges of the crosshead the straps, in operati0n,will not interfere with each other, but each will operate on its 6 special part of the shaft 9 when the lever is oscillated. The lower journal of the shaft 9 is extended through the lower bracketarm, and

to it is secured one end of a sleeve, 14, having an angular socket in its other end receiving the squared upper end of the dasher-rod 15, where it can be detachably secured by a pin, 16, or other device.

The dasher-rod carries cross-arms 17 and at its lower end is furnished with a slat having"; 5 its ends bifurcated, as at 18, the object being to permit the bifurcations to penetrate the butter, so that the latter can be lifted from the churn. The upper end of the dasherrod being detachably held in the socket of the sleeve 14 can be readily removed therefrom and the dasher then lifted from the churn.

As the bracket-arms are nlortised on the standard by simply providing said arms with squared orifices fitted to correspondingly- S5 shaped parts on the standard, and as the standard itself forms the journal for the lever between the bracket-arms, the construction is economical and readily constructed of wood, while the sleeve will be of metal.

The lower bracket-arn1 constitutes a rest on which the lever bears in its oscillatory movements, and all the parts being separable'they can be detached and stored away in a suitable place until required for use.

I am aware that it is not broadly new to operate the dasher-rod of a churn by straps passing from the dasher-rod to arms on a swinging lever pivoted on a standard, as in Letters Patent Nos. 240,508 and 264,598. My construe I00 tion, as described and claimed, differs therefrom in a lever journaled intermediate its ends on a standard and having atits inner end a cross head located at right angles to the lever and swinging between the upper and lower brackets at a point between the jeurnaled part of the lever and the outer ends of the brackets in which the shaft is j ournaled that connects with the dasher-rod. I also so bevel the single cross-head that one end is higher than the other end, so that the straps move without interference with each other. The entire construction is simple, useful, and substantial.

Having thus described my invention, what I claim is- The combination'of the standard, the upper and lower bracket-arms separab] y mounted on the standard to provide an intervening space, the leverjournaled intermediate its ends directly on the standard between the inner ends .naled at its upper and lower ends in the free ends of the bracket-arms, and the straps conneeted with the shaft and the ends of the crosshead, substantially as and for the purposes described.

In testimony whereof I have affixed my signature in presence of two witnesses.
