ROBERT E. L. GROVE, OF DICKSON, TENNESSEE.

CHURN.

To all whom it may concern:

Be it known that 1, ROBERT E. L. GROVE, a citizen of the United States, residing at Dickson, in the county of Dickson and State of Tennessee, have invented a new and useful Churn; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same.

This invention relates to a new and useful churn.

One of the features of the invention is the provision of a collapsible frame, which together with a part of the operating mechanism may be collapsed or folded, so as to consume but a comparatively small space when not in use.

rhllOtllQl feature of the invention is the provision of an operating mechanism in cluding a dasher shaft having a spool, about which cables or cords are wound in such wise and connected to operating levers, in order that a partial rotary movement may be imparted to the dasher shaft in one direction, and then by reversing the levers a reverse rotary motion may be imparted to the dasher shaft.

Another feature of the invention is the provision of adjustable connections between the levers, whereby the strokes of the levers may be changed, in other words, the strokes may be shorter or longer.

In practical fields the details of construction may necessitate alterations, to which the patentee is entitled, provided the alterations fall within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

in the drawings: Figure 1 is a view in side elevation of the improved churn showing the same collapsed. Fig. 2 is a view in side elevation of the churn, showing the parts in readiness to be operated.

Referring more particularly to the draw ings, 1 designates a top member, to which at 2 legs 3 are pivoted. Hinged or otherwise suitably connected at 4 to the legs are the two sections 5 and 6 which are hinged togethcr at 7) of the base 8, which when arranged as shown in Fig. 2 supports the churn receptacle 9.

Mounted in a suitable bearing 10 of the top member 1 is a shaft 11 having a socket Specification of Letters Patent.

Application filed June 18, 1913.

Patented Apr. 28, 1914. Serial No. 774,408.

12 at its lower end, in which the shank 13 of the dasher 14 is adjustably secured by the thumb screw 15. The dasher as shown works in the churn receptacle.

The upper end of the shaft 11 is mounted in a suitable bearing 16 of the arch 17 of the bracket 18, which is secured at 19 to the top member 1. Rotatable with the shaft 11 is a spool or drum 20, and connected to at 21 and wound about the spool or drum in opposite directions are cables 22 and 23, which are in turn connected at 24 to the operating levers 25. These levers 25 are loosely hinged or otherwise connected to the base 8 by the links 26. The levers 25 are connected by the braces 27, each of which consists of four sections 27, 27 27, and 27. The two sections 27 and 27 are hinged together at 28, there being latch bars 29 for holding the sections 27 and 27" alined, while the levers are being operated. By moving the latches 29 out of their keepers 29", the braces 27 may be disposed as shown in Fig. 1, that is, collapsed. The sections 27 telescope into the sections 27", and held in adjusted position by the thumb nut 29 while the sections 27 telescope into the sections 27, and are likewise held in adjusted positions therein by the thumb nut 29. By adjusting the sections 27" and 27 in this manner, the levers 25 are designed to operate with a shorter stroke, as will be seen in Fig. 2. The levers are adapted to engage the yieldable abutments or buffer members 31 of the top member 1 to limit the levers in one direction.

By removing the churn receptacles and the dasher the base may be collapsed and the legs thrown inwardly, in which case the braces may be likewise collapsed, so that the frame may be set aside when not in use, so as to consume but a small space. When the frame and the dasher and churn receptacle are adjusted for operation, the levers may be manipulated backwardly and forwardly, the same working in unison, which will impart an intermittent rotary motion to the shaft 11 and the churn dasher.

The invention having been set forth, what is claimed as new and useful is In a churn; a collapsible frame comprising a body member, legs hingedly connected thereto, a base member hingedly connected to the lower portions of the legs comprising two sections hingedly connected and adapted to support the churn receptacle, an arched bracketon the body member; a churn operating shaft including a drum mounted in bearings of the arched bracket and the body meml'ier; on operating mechanism for the shaft, comprising levers hingedly connected to the base member, extensible connections between said levers, each of said extensible connections including hingedly connected elements whereby said extensible conneo times may be collapsed, locking means for 1 holding said hingedly connected elements :ilined; cushioning butters carried by the opposite sides of the body member to cushion said levers as they are oscillated; and con.- nections between said levers and said drum 5 whereby the operating shaft, may be rocked said trsnne being designed to be collapsed for storage.

in testimony whercoi I have signed my name to this specification in the presence 20 of two subscribing witnesses.
