SPECIFICATION forming partiof Letters Patent No. 791,664, dated June 6, 1 905.

Application filed May.14 =,1904. Serial-No. 207,985. i

To all ivltont it may concern.-

Beit known that I, EMERSON J. WILSON, a citizen of the United States, residing atSouthbend, in the county of Pacific'and State of Washington, have invented new and useful Improvements in Ohurns, of which the following is a specification.

This invention relates to churns, and articularly to reciprocating means to whic an ordinary jar or analogous receptacle may be applied for holding the cream.

The primary object of the invention is to provide a simple and effective churn of that class wherein a reciprocating movement solely is relied upon to form butter without the use of a dasher or other agitating means located within the receptacle for holdingthe cream.

A further object of the invention isto provide anorganization of cooperating elements which will facilitate the application and removal of a jar or other receptacle to the actuating devices and maintain said jar or receptacle in appliedposition with such resistance to accidentaldisengagement that the operating mechanism may be rapidlyactuated without serious conse uences.

A still further object oft einvention is to provide a simple mechanism for reciprocating a support or holder for the containing-receptacle.

With these andother objects and advantages in view the invention consists in the construction and arrangement of the several parts, which will be more fully .hereinafter set forth.

In the drawings, Figure 1 is a side elevation of a churn embodying the features of the invention. Fig. 2 is a front elevation of the same. Fig. 3 is a side elevation of my improved churn, illustrating a modified form of support. Fig. 4 is a front elevation of the same.

Similar numerals of reference are employed to indicate corresponding parts in the views.

The numeral 1 designates an upright or standard having a base 2, adapted to be secured on a suitable support or table by any preferred means. The upper extremity of the standard has a slot 3 longitudinally from'the standard below the lower terminal having a rearwardly-projecting handle or formed therein, and extending rearwardly grip 6 for operating thesamelocated adjacent to the periphery thereof. #BeloW the arm .4 a tubular bearing? extends through the standard or upright 1 and has a shaft 8 rotatably held therein, apinion 9 being secured to the rear end of the shaftand held in continual mesh with the teeth of the gear 5. On the front end of the shaft 8 a crank 10 is secured to rotate with said shaft, the opposite end of said crank being movably attached to the lower terminal of the vertical member 11- of a yoke 12. Extending rearwardly from the upper extremity of the member 11 is a slide projection 13, having a shank 14 extending through the slot 3 in the standard or upright 1 and also through a rear clip or bearing-block 15, the rear end of the shank 14 being threaded and engaged by a nut 16, which closely bears against the block 15. The yoke '12 is also provided With a downwardlyextending curved arm 17, carrying a horizontally-disposed base rest or seat 18. From the upper extremity. of the vertical member 11 a curved arm 19 extends and terminates in a spherical head 20, disposed directly over the center of the base rest or seat 18 and formed with a vertical screw-threaded opening which is engaged by a screw-stem 21, having its lower end connected by suitable swivel means with the center of a closing-cap 22, the upper end of the stem connecting with or continuing into a T-head or grip 23, by which it may be operated. I

Between the base rest or seat 18 and the cap 22 of the yoke 12 an ordinary glass jar or other receptacle 24 is positioned and held in immovable connection with the yoke by adjusting the cap 22 downwardly over the upper open end thereof. It will be understood that thebase rest or seat 18 and cap 22 may have suitable cushioning or packing material applied thereto, the application of such material being an obvious expedient.

In the o eration of the churn (shown in I Figs. 1 an 2) the cream is placed in the jar or rece tacle 24 and the latter applied between t e base rest or seat 18 .and cap 22, as heretofore explained, care being taken to closely fit and adjust the cap over the upper end of the jar or receptacle. 'The gear 5 is then rotated, and the yoke carrying the jar or receptacle will be vertically reci rocated, the rapidity of reciprocation depen ing upon the speed of the operating mechanism. During the reoi rocation of the yoke and the jar or receptac e the cream will be thoroughly agitated and dashed and butter thereby produced, the latter appearing, as in all churns without dashers, in small particles' After the churning operation has been completed the cap 22 is elevated sufficiently to permit the jar or receptacle to be removed, when the butter can be separated from the buttermilk by straining or any other method desired.

The improved churn will be found both expeditious and efficacious in its operation,

and one of the essential features of the same is the ca ability of using as the containingreceptacl e an ordinary jar or other utensil which can be firmly interposed between the base-rest and the closing-cap. It will also be understood that the proportions of the several parts may be varied, and the closingcap and base-rest may be primarily made large enough to adapt utensi s or receptacles of varying capacities to be interposed therebetween.

Referring to Figs. 3 and 4, wherein is illustrated a modified form of support for the churn, it will be noted that the receptacle 24 is supported between a seat 18 and'a cap 22 of the yoke-arm 19, as in the preferred construction. In this form, however, the standard comprises an upright 32, longitudinally slotted at 33 to receive the yoke-arm 34, a reduced portion 35 of which passes through the slot 33 and is held in place by a collar 36 and a nut 37 on said reduced portion 35".

lower portion of the support is branched to The I projecting stud 47, preferably squared to engage a square socket in arm 43, whereby revohition of the wheel 45 will reciprocate the Havin thus fully described the invention, what is c aimed as new is 1. A churn com rising a vertical slotted standard, a yoke aving a receptacle-supporting base at one end, a screw-rod mounted in the opposite end of the yoke, a receptaclecover swiveled to said rod, an arm projecting from the yoke and movable in the slot in the standard, an arm revolubly mounted in the standard and connected to the yoke, and means for revolving said arm to reciprocate the yoke.

2. A churn comprising a standard. vertically slotted for a portion of its length, a yoke having a receptacle-supporting base at one end, a screw-rod mounted in the opposite end of the yoke, a receptacle-cover swiveled to said rod, an arm projecting from said yoke and movable in the slot in the standard, an arm revolubly mounted in the standard supporting a pinion at one end and a crank at the o posite end, said crank being connected to t e yoke, a stud projecting from the standard, and a gear mounted on said stud and arranged to engage the pinion.

In testimony whereof I affix my sign aturc in presence of two witnesses.

EMERSON J. WILSON.
