GI-IAUNGEY A. HAGER, JR., OF 0RD, NEBRASKA POWER-OPERATED ICE-CREAM FREEZER Application filed September 18, 1929. Serial No. 393,409.

10 machine.

A further object ofthe invention is to provide a freezer for household use, the mechanism of which is positioned below the de vice, thereby facilitating an inspection of the cream during thefreezing operation thereof.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved freezer whereby certain important advan- 20 tages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for useas more fully set forth herein.

Other and further objects and advantages of my invention will be obvious from the following detailed description reference being had to the accompanying drawing wherein:

Figure 1 is a view partly in section and partly in elevation illustrating an ice cream freezer attached to the wringer shaft of a power operated washing machine constructed and assembled in accordance with'an embodiment of my invention.

Figure 2 is a side elevation of a novel attaching, driving and supporting means employed; and

Figure 3 is a top plan view of an agitator shaft holding means parts thereof being broken away.

Referring now to the accompanying drawing for a more particular description in which like numerals of reference designate like or corresponding parts the numeral 10 indicates a washing machine provided with a support or legs 11 and having a'motor '12 which is adapted to drive a wringer shaft 13'through a system of gears 14, not shown, contained within a housing 15.

the shaft 13 is provided with a transversely positioned pin 16 through which a removable clothes wringing memher, not shown, may be selectively attached and dettmhed.

The driving shaft 13 which is positionedwithin an elongated housing ,17 is similarly adapted to drive the new'device which comprises a sleeve 18, adapted to'be seated over the housing 17 and secured in a stationary position preferably to the body of the washing machine 10 by means of an arm 19 and a bolt or keeper 20.

The sleeve 18 is provided with a flange 21. A metal bucket 23 is secured to the flange 21 by meansof rivets 24, the latter being inserted through a collar 25. By this means the rivets or keepers 24 are adapted to secure the bottom 23 of the bucket 23 to the sleeve 18 and it will-be understood that a gasket 22 is preferably employed for preventing leakage of ice water. 7 p i As best shown in Figure 2, a rotatable shaft 26 is employed for coupling the later 'described devices to the driving shaft 13. The

rotatable shaft 26 of the new device is provided with a bifurcated lower end 27 thereby forming aislot 28 which is adapted to register with'the transverse pin 16 of the driving shaft 13.

A bushing 28 is provided for the shaft 26 and is adapted to register with the upper edge of the housing 17 of the shaft 13 for supporting the device thereon. v

A- cream container 29 is provided with a bottom 30. The side walls of the container 29 extendbelow its closed bottom 30 as shown in Figure 1 in order that the container may rest upon a fiat surface such as a table during the time it is being filled with cream.

The bottom 30 of the container is provided with a downwardly projecting portion 31 which is bifurcated thereby providing a slot 32, within which is received the lug or pins 33 of the rotatable shaft 26.

It will be understood that the rotatable shaft 26 is adapted to have corresponding movements-with the driving shaft 13, while beingjournalled within and supported by the sleeve or housing 17 of the shaft 13. By

this means corresponding rotary movements are provided for the container 29 at all times that the shaft 13 is revolved.

The container is provided with a cover 34 and a stationary agitator shaft 35, the latter 5 having a plurality of outwardly projecting tax ta-ngs 36 and a plurality of pivotally mounted paddles 37, which, together with the tangs 36, function as agitators for the cream as later described. I

The upper end of the agitator shaft is provided with a portion which is rectangular in cross section as indicated .at 38 and as best shown in Figure 3. Theportion 38 is adapted to be received within a correspondingly shaped notch 39 of a bar 40, provided with down turned fingersll which, as best shown in Figure 1,.are adapted to register with anannular flange 42 formed at the upper edge of the bucket2k By this means the agitatorshaft is held stationary with the bucket 23 at all times while the container 29 is rotated.

In operation the freezer is supporting-ly attachedtothe shaft-13 and the outer'bucket thereof is heldstationary. by any suitable means such as thebolt 20. The iceicream mixture to be frozen is placed within the con tainer 29 and the cover 3413136941 thereon after the container has been placed within the bucket and in register with the driving shaft 26. The detent bar 40 is nowmoved towards the center ofithe bucket 23whereit will be detained by reason of its fingers 41 being in register with the flange 42 of the bucket and at this timethe latch 4230f the member lO'is closed against the shaft 35, a pivot 44 for the latch 43 being provided forthis'purpose.

The space between the container29 and the bucket 23 is now packedwith iceand salt and the motor 12 placed in electrical communication with a closed circuit, not shown.

The high spee-dof the motor 12 is reduced through the gearing A and the motion communicated to the container 23 which, by means of its rapid revoluble movement, will cause the cream tobecome solidified.

From the foregoing description it is thought to be obvious that an ice cream freezer constructed in accordance with myinveution is particularly well adapted for use by reason of .;the convenience and facility with whichit may be operated: and assembled,-an-'d it will also be obvious that my invention is susceptible of-some change andmodification without departing from the principles and spirit-thereof and .for thisreason' Itido .not wish it to'be understood asylimiting myself-to the precise arrangement and formation .of the several parts :herein shown in carrying ,out myinventionin practice, except as hereinafter claimed.
