ROBERT A. THOMPSON AND LUTE P. MORRIS, 0F DALLAS, TEXAS, ASSIGNORS TO INTERNATIONAL MANUFACTURING COMPANY OF TEXAS, OF DALLAS,

TEXAS.

GHURNING DEVICE.

Specification of Letters Patent.

Patented June 15,1920.

To all whom it may concern:

Be it known that we, Ronnn'r A. THOMP- soN and horn P. ll/IORRIS, citizens of the United States, residin' at Dallas, in the county of Dallas and btate of Texas, have invented certain new and useful Improvements in Churning Devices, of which the following is a specification.

This invention pertains to new and useful improvements in churning devices.

The object of the invention is to provide a carrier for the churning receptacle and means for reciprocating the same and to embody in the carrier certain novel and advantageous features making for ease oi operation, simplicity. convenience ll] handling, and economical manufacture.

In carrying out the invention a. carrier is formed of a cap and a carrier plate, the latter having a iiat lip to facilitate the insertion of the churn can and an upstanding llange tohold said can in place; while the cap has a conical shape and a. depending annular flange hearing on the cover of the can. and receiving the cover which is also conical. Other features consist of ears on the cap and plate for receiving the connecting bolts and eyes upset from the said cap and plate for receiving the reciprocating springs.

The invention will be more readily understood from a reading of the following speci fication and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Figure 1 is an elevation of a churning device embodying the invention,

F ig. 2 is a partial elevation of the carrier and can on an enlarged scale,

Fig. 3 is a detail of the cap and can cover,

Fig. 1 is an underside View of the cap,

Fig. 5 is a plan view of the plate,

Fig. 6 is a cross-section on the line 6-6 of Fig. 4, and

Fig. 7 is a cross-section on the line 77 of Fi 5.

n the drawings the numeral 10 designates a circular supporting plate having diametrically opposite ears 11. An upstanding mar inal flange 12 is provided on one circunerential edge betwen the ears, while the other or front edge is flattened to form a lip 13. A churning receptacle or can 14 is placed on the plate and the lip facilitates the insertion of the can, while the flange 12 holds it against displacement.

A conical cap 15 corresponds in shape to the plate 10 and is provided with diametrically op )osito cars 16. An annular flange 17 depends from the margin of the cap. Elongated bolts 18 ha re their heads engaging in the ears 1 l and extend up through the cars 16; the upper ends of the bolts receiving wing nuts 19. The cap is made conical in order to receive the conical cover 211 oi the can 11 and the flange 1? is less in (ii-- ametcr than the cover so as to rest thereon and permit the cover to project up into the cap. liy screwing down the nuts 19 the plate 10 and cap 15 are drawn toward each other and the cover forced down on the can which is thus clamped in the carrier. The conical cap and cover and the depending flange 19 coact to hold the churning receptacle against lateral displacement at the top.

At the center of the cap and also the plate, an eye 21 is upset from the metal and each receives the one end of coiled spring 22. These eyes form a convenient and inexpensive means of fastening the springs to the carrier. One end of the lower spring 22 is attached to a stationary eye 23; while the upper end of the upper spring is connected with a bracket '21 mounted on an upright support.

When it is desired to remove the can 14 it is only necessary to loosen the nuts 19 sinliciently to swing the lower end of the can outward over the lip 13, which latter being fiat permits such a removal more readily than it the flange 12 extended entirely around the plate. lVhen the can is to be placed in the carrier the lip acts as a guide and affords an easy insertion. By provision of the lip a minimum extension of the carrier is gained and thus it is not necessary to rotate the wings to a great extent.

In using the churn the can 14 with its contents are placed in the carrier and the nuts 19 screwed down to fasten the can in place. The operator forces the carrier by pressing on the cap 15, thereby extending the upper spring 22 which brings the carrier up when pressure is relieved on the cap. When the carrier moves upward the momentum is sufficient to send it above a central position, thus extending the lower spring which assists in the next downward stroke. It Will be seen that very little effort is required on the part of'the 0 erator and the reciprocation of the can will agitate the contents and efficiently churn in a remarkably short period.

What we claim is:

1. In a churning devirc, the combination with a churn receptacle, of a supporting plate having an upstanding flan e and a fiat lip for receiving the bottom 0? the recep tacle, a cap having a depending flange hearing on the cover of the churning rereptarle, and connections between the rap and plate for clamping the receptacle in the carrier.

2. In a churning device, the (fOITlblllRtlOfl with a churning receptacle, of a supporting plate having an upstanding flange and a flat lip for receiving the hotton'i oi the recon tacle, a rap having a depending flange hear ing on the rover of the churning receptacle, and connections between the cap and plate for clampin the receptacle in the carrier, the plate an cap each having an eye upset from the center thereof to connect with a reciprocating spring.

In a churning device, the combination with a churn receptacle, of a carrier including, a circular supporting plate having a flat lip and diametricall opposite ears, a circular rap having a (lepending annular flange hearing on the cover of the receptacle and also provided with diametrically opposite ears, bolts extending from the ears 0 the plate to the ears of the rap and wing nuts mounted on the bolts, the cap and plate each having an upset central eye for attaching a coiled spring thereto.

11 testimony whereof we aiiix our signaturns.
