FREEZER.

Specification of Letters Patent.

Patented July 16, 1912.

Application filed October 19, 1911. Serial No. 655,494.

To all whom it may concern:

Be it known that I, VILHELM AUcUsr MODEL, a subject of the King of lVurttemberg, and residing at Feuerbach, near Stuttgart, in the German Empire, have invented certain new and useful Improvements in Freezers, of which the following is a specification.

My present invention relates to agitating devices such as freezers or the like which comprise a bucket or stationary receptacle and a smaller receptacle revoluble within the stationary receptacle, and such other devices, as for example, dashers which appertain thereto.

The principal objects of my invention are to provide a bridge member which spans the mouth of the bucket and supports the inner revoluble receptacle, with respect to its axis for actuation, the said bridge member and appertaining parts being such as to facilitate assembling of the various members in operative relation to each other or dismembering of the device; to simplify the device as a whole; and, to enable the parts to be brought into operative relation to each other regardless of distortion of some of the elements, such as shrinkage or expansion of the material of which the bucket is formed due to dryness or dampness to which they are usually subjected. v

In the drawings, forming a part of this specification :Figure 1 is a top plan View of a freezer embodying my invention. Fig. 2 is a fragmentary vertical central sectional view through the freezer embodying my invention.

In the drawings, where similar characters refer to similar parts, the invention is disclosed as applied to an ice cream freezer, which comprises generally, a bucket or outer receptacle 1, an inner receptacle 2, and a bridge member 3, spanning the mouth of the former and stabilizing the latter.

The outer receptacle is provided with two upstanding pins or lugs 1 and 5, spaced apart from each other adjacent the upper margin thereof. At the opposite side of the receptacle 1, from the pins 1 and 5, is another upstanding pin or lug 6, having a notch 14, for a purpose to be subsequently disclosed.

The inner receptacle 3 is mounted to revolve within the receptacle 1, in any suitable manner, not shown in the drawings,

and stabilized with respect to its axis of rotation by the bridge member 3.

In orderto operatively support the receptacle 2 as described, the bridge member 3 is provided with a socket member 10 which receives an upstanding annular flange 11 on the cover of the receptacle 2, while the dasher spindle 9, is formed polygonal at its end and is received by a complementary formed aperture 8 in the bridge member 3. The bridge member 8 has an aperture 7, adjacent its end, permitting such member to embrace the pin (3 in such a manner that the notch 14 is disposed, in part, above the top of the member 8. Adjacent this aperture 7, the member 3 carries a bolt 13, pivoted on pin 12, which may be turned to project into the notch 14 and bind the bridge member against the top of the receptacle 1.

In assembling the device, the receptacle 2 and dasher spindle 9 are positioned within the receptacle 1. The bridge member 3 is then placed with its one end between pins 4 and 5, and its other end embracing the pin 6. It is to be noted that, because of the relative coaction of the pins 4:-5 and pin 6, with the bridge member 3, the latter may be let down in place between pins 4 and 5 and embrace pin 6, to receive and stabilize the receptacle 2 and dasher spindle 9, by

movement in a vertical plane. This means of assemblage, is in contradistinction to known devices where a loop is provided for one end of the bridge member and in assemblage the bridge member is first placed diagonal with its end inserted into such loop, which then forms a pivot to swing the bridge member in place. This last described procedure of assemblage is objectionable inasmuch as the bearing for the inner receptacle and dasher spindle must be made relatively larger than the members they receive in or der to allow the bridge member to be swung in place. It is further to be noted that the receptacle 1, in practice, is usually made of wood which contracts and expands so that the diameter is altered according to whether the bucket is exposed to dryness or dampness and consequently the distance between the pins 4:-5 and pin 6 is seldom uniform. By the disposition of parts, according to my invention, considerable alteration of the bucket will not render the device inoperative, since the bridge member is retained in a rigid position against upward movement by the bolt 13, at one end only of the member and as a result there is no positive position where the other end of such member must engage the pins 4: and 5, so long as such ends remain intermediate the said pins.

In other words, the bucket 1 may shrink or be bent to assume an oval cross section and such alteration will only effect the positioning of the pins at and 5 longitudinally of the member 3, they, the pins, still preventing lateral displacement of the member 3.

I claim 1. In a device of the character described,

the combination of an outer receptacle, an

inner receptacle, two upstanding lugs adjacent the margin of said outer receptacle,

2. In a device of the character described, the combination of an outer receptacle, an inner receptacle carrying an upstanding annular flange, a dasher spindle projecting from and above said inner receptacle concentric to said flange and having a polygonal end, two upstanding lugs adjacent the margin of said outer receptacle, another upstanding lug, opposite said first mentioned lugs, adjacent the margin of said outer receptacle, a bridge member, spanning the mouth of said outer receptacle and provided with a socket adapted to receive said flange of said receptacle and an aperture formed complementary to said spindle end to receive the same for stabilizing the receptacle and spindle, said bridge member being adapted to lie between said first mentioned lugs and embrace said second mentioned lug, and a device adapted to coact with said second mentioned lug to normally prevent upward movement of said bridge member.

In testimony whereof I aflix my signature in presence of two witnesses.
