ALLEN BURCH, OF FULTON, MISSISSIPPI.

Specification of Letters Patent.

' atentod Mar. .1, 19110.

Application filed November 4, 1909. Serial No. 526,236.

To all whom it may concern:

Be it known that I, ALLEN BURCH, a citizen of the United States, residing at Fulton, in the county of Itawamba and State of Mississippi, have invented a new and useful Churn, of which the following is a specification.

The objects of the invention are, generally, the provision in a n'ierchantable form, of a device of the above mentioned class, which shall be inexpensive to manufacture, facile in operation, and devoid of complicated parts; specifically, the provision of a simporting frame of novel and improved construction; of a shaft for the rotation of the dasher of the churn; of lever mechanism operatively connected in a novel manner with the shaft; of novel means for limiting the movement of the lever; and of a dasher of novel and improved construction; other and further objects being made manifest hereinafter as the description of the invention progresses.

The drawings show but one form of the invention, and it is to be understood that changes, properly falling within the scope of what is claimed, may be made, without departing from the spirit of the invention.

Similar numerals of reference are employed to denote corresponding parts throughout the several figures of the drawing, wherein Figure l is a perspective; Fig. 2 is a sectional detail, parts being in elevation; and Fig. 3 is a fragmental top plan of the operating lever, parts being shown in section.

The fundamental member of the device is a frame, which may be of any form. In the present instance, the frame comprises diverging legs 1, connected by side bars 2, the adjacent faces of which are parallel to each other, the side bars being connected by cross pieces 3, from which rise corner standards 4, connected by caps 5, braces 6, uniting with the caps 5 and with the standards 4 to complete the upper extremity of the frame.

Secured to one of the cross pieces 3 and to one of the caps 5 is an upright fulcrum post 7, to which the lever for operating the device is pivoted. As shown most clearly in Fig. 3 of the drawings, this lever comprises an arm 25 provided at one end with bifurcations 9 whereby the lever is pivotally assembled with the fulcrum post 7. Intermediate its ends, the arm is bent to form a lateral extension 20. and between the extension 26 and the bifurcations S), the arm 25 carries an outstanding lug .28. The end of the arm 25 is adapted to be inserted into a handle 8, the handle 8 abutting against one end of the extension 20. Mounted in the end of the handle 8 is a pin 21, prolonged through the lateral extension 26 of the arm 25, the lug 28 being adapted to receive the end of the pin 21, so that the pin may not accidentally be displaced. The arm 25 is secured to the handle 8 by means of a transverse rctaining element 29, a screw or the like. The extension 26 of the arm is adapted to receive a shaft 10 provided with spirally disposed slots 11, the pin 21 being adapted to extend through the slots 11. A. wear plate 22 is mounted upon the lower face of one of the caps 5 and through this wear plate 22 extends a pin 12, which is mounted in the upper extremity of the shaft 1.0.

Mounted upon one of the cross pieces 3. is a thrust plate 15, through which passes a rod 14, carrying at its lower end, the dasher. The upper end of the rod let extends into the lower end of the shaft 10 and is secured therein by means of a set screw 16 which is radially inserted into the shaft 10 adjacent the lower end thereof. The thrust-plate 15 extends beyond the cross piece 3 upon which it is mounted, and is bent upwardly and curved inwardly, as denoted by the numeral 17, toward the shaft 10. This portion 17 of the thrust-plate is rendered resilient, and is adapted to receive the handle 8 as the lever of which the handle 8 is a component part, moves downwardly. The resilient head 17 of the thrust-plate is adapted to receive yieldingly, the lever, as the machine is operated, and to prevent the lever from working with a jar or shock, as the handle-end 8 of the lever is reciprocated. Moreover, the portion 17 of the thrust-plate serves to space the handle 8 against contact with the set screw 16, it being noted that as the portion 17 of the thrust-plate is compressed by the handle 8, it is impossible for said portion 17 to strike the set screw 16 as the latter rotates with the shaft 10.

The dasher which is assembled with the lower end of the rod 14: is fashioned from a single piece of metal, cruciform in outline,

opposite arms 18 thereof being upwardly bent, and opposite arms 19 thereof being downwardly bent, the lateral edges of all of the arms being outwardly flexed, as denoted by the numeral 20.

The construction last above described results in a dasher simple in construction, and easily manufactured, yet efiicient in operation.

The operation of the device will probably be evident from the foregoing description, but it may be stated briefly, at this point, that when the handle 8 of the lever is reciprocated vertically, the pin 21 moving in the slots 11 of the shaft 10, will cause a rotation of the shaft, the shaft carrying with it, in its rotation, the rod 14, and the rod let causing a rotating of the dasher. within the cream receptacle, the upturned end 17 of the thrust-plate receiving, yieldingly, the handle 8 upon its down stroke, and preventing the handle as it is reciprocated, from coming into contact with the set screw 16, as the latter rotates with the shaft 10.

Having thus described the invention, what is claimed is 1. A device of the class described comprising a frame; an arm pivoted at one end to the frame, and bent, intermediate its ends, to form a lateral extension; a handle arranged to engage the other end of the arm; a pin mounted in the arm and prolonged through the extension, there being a lug upon the arm to receive the other end of the pin; a dasher; and means engageable by the pin to operate the dasher.

2. A device of the class described comprising a frame; an arm pivoted at one end to the frame, and bent, intermediate its ends, I

to form a lateral extension; a handle arranged to engage the other end of the arm and to abut terminally against the extension; a pin mounted in one end ofthe arm and prolonged through the extension, there being a lug upon the arm to receive the other end of the pin; a dasher; and means en gageable by the pin to rotate the dasher.

3. A device of the class described comprising a frame; a thrust-plate mounted thereon; a shaft resting upon the thrustplate and rotatable thereon; a dasher operable by the shaft; a lever fulcrumed in the frame and operatively connected with the shaft; the extremity of the thrust-plate being arranged to receive the lever.

4. A device of the class described comprising a frame; a thrust-plate mounted thereon; a shaft resting upon the thrustplate and rotatable thereon; a dasher operable by the shaft; a lever fulcrumed in the frame and operatively connected with the shaft; the thrust-plate having a resilient, upwardly curved end to receive the lever.

5. A device of the class described comprising a frame; a thrust-plate mounted thereon; a rod rotatably mounted in the thrust-plate; a dasher carried by the rod; a shaft resting upon the thrust-plate and inclosing one end of rod; means projecting from the shaft for connecting the shaft with the rod; and a lever fulcrumed in the frame and operatively connected with the shaft; the thrust-plate having a resilient upwardly curved end to receive the lever, to space the same against contact with the connecting means.

(3. A churn-dasher fashioned from a cruciform piece of material, having opposite of its arms upwardly inclined, and opposite of its arms downwardly inclined, the lateral edges of all of said arms being outwardly bent.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
