Application filed June 18, 1913. Serial No. 774,447.

To all whom it may concern:

Be it known that I, GEORGE E. SLATER, a citizen of the United States, residing at Graceville, in the county of Jackson and State of Florida, have invented a new and useful Churn- Operating Mechanism, of which the following is a specification.

The present invention appertains generally to churns, and relates more particularly to a novel and improved mechanism for actuating churns.

One of the objects of the present invention is to provide a mechanism of the character indicated applicable to various churns, for operating the same, in a convenient and efficient manner.

Another object of the present invention is to provide a mechanism of that character embodying an adjustable base or platform for the churn body, in order that the mechanism may accommodate various sizes, or proportions of churn bodies.

A further object of the present invention is to provide novel means for adjusting the stroke given the dasher staff or rod, in order that the dasher may be actuated through a predetermined distance, according to the size of the churn body.

A still further object of the present invention is to rovide a mechanism of the character specified embodying a novel and improved frame for receiving and holding the churn body, the actuating mechanism being attachable with the ordinary dasher staff for reciprocating the same.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being under stood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawings, wherein Figure 1 is a perspective view of the mechanism, as in use. Fig. 2 is a fragmental elevation of the device, illustrating the gear or means for actuating the dasher staff. Fig. 3 is another elevation of the parts depicted in Fig. 2, this view being taken at right angles to the line of view of Fig. 2, and parts being shown in section.

In carrying out the present invention, reference being had in detail to the drawings, there is provided a suitable supporting frame denoted generally by the numeral 1. This frame is preferably constructed of strips or bars, and embodies a pair of parallel bars 2 having their ends bent downwardly into feet 3 for supporting the frame on the floor or other surface. The frame further includes a pair of inverted V-shaped bars 4 carried by the bars or base members 2. Each of the bars or standards 4: has its ends or limbs riveted upon the respective bar or base member 2 adjoining the respective feet 3, it being observed that the standards or upright members 4 are disposed parallel with each other. The apices of the stand ards or supports 4 are connected by a cross piece or beam 5, and one pair of limbs of the standards 4 are preferably connected by diagonal braces 6 to steady the frame or structure.

The frame 1 is provided with novel means for supporting the churn body, and to this end, four vertical or upright strips 7 have their respective ends riveted to the bars 2 and the respective limbs of the standards 4. The strips or upright members 7 are each provided with a series of key-hole openings 8, the heads of which are disposed uppermost, and the tails of which extend downwardly. The platform or base'9 is adapted to be supported by the strips 7 the said platform having the headed studs 10 at its corners, and the studs being adapted to engage through the respective key-hole openings 8 to support the platform, it being observed that the platform may be adjusted vertically by engaging the studs through the key-hole openings at various heights. In engaging the headed studs 10 in the respective keyho e openings, said studs are first engaged through the heads of the key-hole openings, and the platform in settling or gravitating will cause the studs to move into the tails of key-hole openings to tightly and firmly hold the platform in position. It is evident that the strips 7 are adapted to be sprung in engaging and disengaging the platform or base to and from the said strips.

Upon the platform or base 9 is seated or disposed any ordinary churn body 11, into which the usual dasher staff or red 12 extends. It will be understood that the present staff is adapted to pass through an aperture.

13 provided inthe central portion of the beam 5, so that the free or outer end of the dasher staff protrudes above the beam 5, or the frame of the device.

As a means for actuating or reciprocating the dasher staff, there has been provided the following structure: A suitable frame denoted generally by the numeral 14, is carried by the main frame 1 of the device, the supplemental or gear frame 14 being more or less arbitrarily or conventionally illustratedin' the drawings. As illustrated, the frame 14 embodies a cross strip or bar 15 terminallyv riveted or secured to the respective limbs of the standard 4, and a similar cross strip or bar 16 is similarly secured to the said limbs intermediate the apices and the lower ends of the standards, the strip 15 being disposed adjoining the apices of the standards. The frame 14 further includes an angular bar 17 terminally secured to the respective strips or

bars

15 and 16, so that its arms are disposed vertically and horizontally, respectively. Similar angular bars 18 have their ends or terminals riveted or secured to the respective limbs of the standards, adjoining the

respective strips

15 and 16, the arms of the bars or members 18 being disposed horizontally and vertically, respectively. The elbows of the respective bars or

angular members

18 and 17 are disposed in opposite directions, as clearly seen in Fig. 3. A cross strip or bar .19 is terminally secured to the elbows of the angular members 18, while an upright strip 20 is terminally secured to the

strips

19 and 16 intermediate the angular members 18. An upright member or standard 21 is carried by the lower horizontal arm of the angular member 17. The frame 14 carries a suitable train of gears adapted to be actuated by hand, for reciprocating the dasher stafi, as will hereinafter appear. An actuating shaft 22 is journaled through the upright arm of the member 17 and through the upright strip 20 adjoining their upper ends, and has a suitable hand crank 23 at its outer end. A large gear wheel 24 is keyed upon the shaft 22 adjoining the member 17 and a counter shaft 25 is journaled through the

members

17 and 20 below the shaft 22. The counter shaft 25 has a pinion 26 keyed thereon which intermeshes with the gear wheel 24, the pinion being of relative small diameter, in order that the shaft 25 will be rotated at a greater velocity than the shaft 22. The shaft 25 also carries a balance or fly wheel 27 in order to assist the train of gears in running easily. A second counter shaft or crank shaft 28 is journaled through the member 17 and through the pedestal 21 below the shaft 25, and has a gear wheel 29 keyed thereon intermediate the member 17 and pedestal 21. The gear wheel 29 intermeshes with the pinion 26. The inner end of the crank shaft 28 projects beyond the member 17, a balance or fly wheel 30 being mounted on the shaft 28 adjoining its inner end. The

balance wheels

27 and 30 permit the actuating gears to run easily or lightly, it being noted that the entire actuating mechanism is compact. The crank shaft 28 is operativelyconnected with the dasher staff in a novel manner and to this end, an extensible or'adjustable crank 31 is secured to the inner end of the shaft 28. The crank embodies a slotted section 32 secured to the shaft 28 and a second section 33 carrying set screws 34 working through the slot of the section 32, in order that when the set screws are tightened, the

sections

32 and 33 will be locked in position with respect to each other. The set screws permit of the adjustment of the crank, as will be apparent. The outer section 33 carries the wrist pin 35, said wrist pin being adjustable with the section 33 in order that it maybe disposed at various radii with respect to the aXis of the shaft 28. The pit-man 36 is loosely connected to the wrist pin 35 and is attachable at its upper end with the upper end of the dasher staff. The pitman 36 is conveniently coupling 37, which embodies a clamp 38 to embrace the upper portion of the dasher staff 12 and to which the pitman 36 is pivoted. The pitman is conveniently pivoted to the clasp 28 by means of a second clamp 39 embracing the pitman and pivoted to the clamp 38. s

In use, it is evident that the present device may be readilyadjusted to accommodate various hand churns. Thus, the platform 9 may be adjusted to the proper height to accommodate the particular churn body, while the crank 31 may be adjusted to give a proper throw or reciprocation to the dasher staff 12, it being observed that the pitman 36 is readily attached to the dasher staff. By rotating the crank 23 manually, the dasher staff may be reciprocated through the meiio dium of the gears, crank and pitman, it

iso

capabilities of the present invention will be apparent to those versed in the art, it being observed that the objects aimed at have been carried out satisfactorily, and that the present device is a desirable one for the purposes for which it is designed.

What is claimed is 1. In a device of the character described, a frame, a platform adjustably carried thereby, the frame including an upper guide above the platform, a dasher stafi slidable through the said guide, an actuating mechanism carried by the frame including an eX- tensible crank, an upwardly projecting pitman connected to the crank, and means for adj ustably, pivotally and detachably connecting the upper end portions of the pitman and dasher staff above the said guide.

2. In a device of the character described, base members, a pair of inverted V-shaped standards, upright members connecting the limbs of the standards and the base members, a beam connecting the apices of the standards, a platform adjustably carried by the upright members, a dasher staff slidable through the said beam, a frame secured to a pair of limbs of the standards, an actuating mechanism carried by the frame and including an extensible crank, an upwardly projecting pitman connected to the crank, and means for adjustably, pivotally and detachably connecting the upper end portions of the pitman and dasher staff.
