ICE-CREJLM FREEZER.
, Application filed October 17, 1919.
To all whom it may concern:
Be it known that I, JOHN C ARK, a citizen of the United States, residing at Flint, in the county of Genesee and State of Michigan have invented certain new and useful Improvements in Ice- Cream Freezers, of which the following is a specification.
The present invention comprehends; generally improvements in that class of inventions known as agitating and more particularly relates to an ice cream freezer.
It is the principal aim and object of the present invention to provide a device of the abovementioned character wherein agitating means of an improved construction is employed for insuring of the thorough mixing of the material during the operation of the device and at the same time is capable of being quickly taken apart so that the component parts may be cleaned.
It is an equally important object of this invention to provide a device of the above mentioned character wherein improved means is provided for mounting the inner or material containing receptacle and the agitating means while acting in conjunction therewith is suitable means for operating the agitating means and receptacle in opposite directions.
The invention also embraces the provision of a device of the above mentioned character wherein improved means is employed for releasably supporting the mean stationary receptacle in a proper position.
Among the other aims and objects of this invention may be recited the provision of a device of the above mentioned character wherein the number of parts are comparatively few, the construction simple, the cost of production low and the efliciency high.
The improvements in the details and arrangement of parts will be apparent from an inspection of the accompanying drawings, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is disclosed "for the purpose of imparting a full understanding of the invention.
The invention is clearly illustrated in the accompanying drawings, in which:
Figure 1 is a side elevation,
Fig. 2 is a vertical cross sectional view thereof, taken on line 2-2 of Fig. 1 in th direction in which the arrows point,

which the arrows point,
Patented Aug. 31, 1920 Serial No. 331,364.
on line 33 of Fig. 2 in the direction in Fig.4 is-a top plan view of the device F 1g. is an enlarged bottom plan view oi the mam receptacle, r
Fig. 6 is a perspective detail of one of the I supporting brackets for the main receptacle Fig. is a perspective detail of one of the agitating members,
Fig. 8 is a perspective detail of one section of the supporting shaft, 7 I
Fig. 9 is a perspective detail ofthe other section of the supporting shaft, and I Fig. 10 is a perspective detail of the lower supporting bracket for the main receptacle. Similar characters of reference are' em ployed in all of the above described views, to indicate corresponding parts.
Referring now, more particularly, to the accompanying drawings there are provided spaced supporting brackets land 2, the lower of which is desirably formed near its outer end with a stud 3, preferably square in cross section, while the outer edge of the upper bracket is formed with a curved recess 4 while the portions of the bracket lying to the sides of the recess are bifurcated forming spaced pairs of horizontally dis-' posed ears 5. An arm 6 curved to conform to the curvature of the recess 4 is now employed, the respective ends being reduced, one reduced end 7 being pivoted between one pair of the ears 5 by'a suitable fastener such as a pin 8 while the other reduced end is apertured and at times is receivable between the other pair of ears 5 and releasably locked in engaged position by means of a locking pin 9 which is preferably flexibly connected to the upper arm through the in-" strumentality of a chain 10.-
A main outer receptacle 11 is now disposed between the arms or brackets 1 and 2 and has attached centrally to its under surface a recess bearing plate 12 which is engaged over the stud 3 for insuring of the maintenance of the receptacle in a stationary position. A cross bar 13 is disposed across the upper edge of the main receptacle and is formed medially ofits ends with a large bearing opening 14 while its opposite ends are apertured and releasably fitted over the oppositely positioned threaded pins 15 which project from the upperedge of the main receptacle, while clamping elements such as wing nuts 16 are engaged, with the threaded pins for clamping the cross bar in position.
Removably arranged within the main receptacle is a material receiving receptacle 17 the lower portion of which is rotatably mounted in the main receptacle, preferably by means of a depending stud 18 which pro 1 jects'centrally from the under surface of the bottom and which is journaled in a recessed bearing 19 carried centrally on the upper surface of the bottom of the main receptacle. Removably telescoped on-the up per edge of the receptacle 17 is a flanged cover 20 which is formed withacentralwheel for a purpose that will presently appear.
' As intimated, improved agitating means has been employed and in reducing this feature of the invention to practice there is provided a shaft indicated in its entirety by the numeral 24: and preferably composed of sections 25 and 26. The section 25 is substantially rectangular in cross section while the section 26 is constructed in a plate-like form and has formed integrally with one face a vertically disposed rib' 27 designed to engage the adjacent vertical groove 28 in the section 25 when the sections are fitted together. In addition, the section 25 is provided with a vertical series of horizontally disposed grooves 29, the inner walls of which are formed medially of the side edges with lugs 30 both for a purpose that will appear. A plurality of relatively narrow and flat agitating bars generally designated by the numeral 31 each have their side edges formed with opposed recesses 32 at points medially of the ends, the end portions of the bars being designed to act as agitating blades 38 when the recessed portions are fitted in the horizontal grooves and locked against displacement by the rib 27 and the adjacent lugs 30 which engage the recesses 32, as is apparent. Suitable fasteners such as'screws 34: are anchored near the ends of the sections for detachably fastenfor preventing the'accidental displacement of the agitating bars. The shaft and bars form a substantial paddle while a stud 35 is formed on the lower end of the section 25 and is journaled in a recessed bearing 36 4 formed centrallyon the upper surface of the bottom of the material containing receptacle 17. The upper portion of the section 25 is ing the sections of the shaft together and rounded as at 37 and journaled through the upstanding collar 22, the extreme upper end of the rounded portion being squared as at 38 and designed to receive a pulley wheel 39 fora purpose which will presently apear.
Suitable means for rotating the shaft and the inner receptacle 17 in opposite directions, in the present instance may be said to consist of spaced brackets 10 in which is journaled a vertical shaft d1. Carried by the upper portion of the shaft are spaced pulleywheels 42 and 13 which arerespectively arranged in opposed relation to the collar orwheel 23 and the pulley wheel 39. Belts 1a ands?) are trained about the respectively opposed pulley wheels while the upper belt 45 is crossed as shown in Fig. at, to insure of the rotation of the shaft in an opposite direction to the rotation of the receptacle 17. Suitable operating means such as a crankhandle 4:6 is detachably connected to the upper squared end of the shaft ii to facilitate the rotation of the latter to insure of the operation of the device.
In use, upon rotating the handle 16 rotary motion will be transmitted from the shaft 11 to the shaft 24: by means of the belt and pulley wheels 13, 89 and 4L5 respectively and likewise rotary motion will be transmitted from the shaft ll'to the receptacle 17 by means of the belt 16 which operates about'the pulley wheel 42 on the shaft tl and the grooved collar or pulley wheel 23 which is formed with the collar 22 on the cover of the receptacle 17, the crossing of the belt 45 insuring of the rotation of the shaft and receptacle 17 in opposite directions. In detaching the parts, it is only necessary to remove the pulley wheels 39 from the shaft and release the locking pin 9 and then raise or remove the cover 20 and at the same time remove the cross bar subsequent of course to unscrewing the wing nuts 16, the agitating means may now be removed from the receptacle 17 and disconnected and cleaned while likewise the receptacle 17 may be removed from the main receptacle which latter in-turn may be removed from the supporting bracket. It is of course apparent that when ice cream is being made, the material is placedin the receptacle17 while the main receptacle is filled with ice but of course when'butter is being churned, the main receptacle is left empty.
It is believed in view of the foregoing description that a further detailed description of the operation of the invention is entirely unnecessary. Likewise it is believed that the advantages of the invention will be readily apparent. I r 7 Still further embodiments of the invention than those herein especially defined may be resorted to as conditions or preference may dictate, as may be in keeping with the hereto ap )ended claims.
