JOSIAH P. PERKINS, OF INDIANAPOLIS, INDIANA.

ICE-CREAM FREEZER.

SPECIFICATION forming part of Letters Patent No. 683,791, dated October 1, 1901.

Application filed August 16, 1900. Serial No. 27,032. (No model.)

To all whom it may concern.-

Be it known that I, JOSIAH P. PERKINS, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Ice-Cream Freezer; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

The object of this invention is to make an ice-cream freezer of the class which during the freezing process is in an inclined position simple, economical, and at the same time practical and efficient.

The full nature of this invention will be understood from the accompanying drawings and the description following of one form of device embodying said invention, and the scope of said invention will be understood from the claims following said description.

In the drawings, Figure 1 is a central vertical section of the freezer. Fig. 2 is a plan of a portion of the base, it being partly broken away. Fig. 3 is a plan of the worker and scraper. Fig. 4 is a side elevation of the same. Fig. 5 is a, horizontal section of the scraper enlarged. Fig. 6 is a central vertical section of the parts at the joint between the cream-can and ice-receptacle, parts bein g broken away.

Referring now to the details of construction, a base is provided and, as shown herein, consists of two boards marked 1,secured parallel with each other to end cross-pieces 2,so as to leave between saidboardsanarrowslit or openin g. The Vessels of the apparatus are supported by a spindle 3, the upper end of which extends through said vessels, and the lower end or shank 4 is bent at a right angle to the upper end. One of the important features in the construction of this spindle or support is that it has substantially the same diameter for its full length, including the portions 3 and 4, and without any enlargement or shoulders, so that it can be obtained readily and cheaply, for it consists only of asmooth rod, which is kept in stock and is of no special design. The spindle and shank is made by merely bending the rod to form a right-angle bend to form a bearing for the vessels. The shank 1 is riveted to a vertical plate 5, secured on the pivot or bearing 6, that rests on the boards 1 and that is held in place by the bearing-plates 7 in such manner that the plate 5 extends through and operates in the slot or opening between the boards 1, as shown in Figs. 1 and 2. On one side said plate 5 is notched, there being a series of notches shown shaped to receive the lockingbar 8, that is pivotally connected at 9 to the base and is oscillated horizontally. The free end of this locking-bar is held down by the pin 39, screwed into the base, with the upper end bent or turned horizontally, so that the locking-bar can be slipped in and out. free end of thelocking-bar is upturned at 10 to form a finger-piece for its manipulation. The purpose of the foregoing construction is to securely hold the vessels of the ice-cream freezer in position and-t0 enable the position of the same to be adjusted.

The cream-can 15 has a concavo-convex bottom, with the convex surface downward, and has a hole through its bottom central to receive the bearing-sleeve 11, which is secured to the bottom water-tight. This sleeve is preferably made of gas-pipe and extended below the bottom of the cream-can, and its lower end is externally threaded. Another sleeve 16, made of tin, surrounds the sleeve 11 and extends almost to the top of the creamcan. These two sleeves may be substituted by one sleeve, as they perform the function of one sleeve and are made in the manner here shown for the sake of convenience and cheapness. The sleeve 16 is secured at its lower end to the bottom of the cream-can and is reinforced by the ring 17.

The ice-receptacle 14 is a bucket smaller at the bottom than at the top, with the bottom fiat and centrally provided with a hole 26. The cream-can is then inserted in the bucket, the lower end of the sleeve 11 being passed through the hole 26. The convex surface of the bottom of the cream-can therefore rests upon the rectangular irregular edge of the bucket bottom about the hole 26, so that when the cream-can is clamped down tight against the bottom of the bucket it will make a water-tight joint. Then the top connecting the bucket and cream-can is put in place,

as hereinafter explained, the washer 13 is slipped over the sleeve 11, and the nut 12 screwed up against it. The top of the washer The V .the concave surface of the washer.

13 is flat, bearing against the bottom of the bucket; but'its under side is concave. The upper side of the nut 12 is convex to fit in When the nut 12 is screwed up tight, the parts are held together, so as to make a water-tight joint between the two vessels. The upper end of the cream-can is turned outward and downward to form the flange or lip 18, which receives the upper edge of the top 19 of the bu eket or ice-receptacle. The top 19 is formed of tin, the main body being inclined when in place about forty-five degrees, with an upwardly-extending flange 20 at one end to enter and fit within the flange or lip 18 of the cream-can and with a downwardly-extending flange 21 at the other end to fit over the outside of the bucket 14- This lower flange 21 is secured to the bucket by a means that presses in the lower edge of said flange, embedding it into the wall of the bucket somewhat, so that really said flange 21 is turned in to be in line with or parallel with the wall of the bucket, whose lower end is smaller than the upper end and makes the outside line of the bucket inclined. The lip or flange 18 of the upper end of the cream-can is clamped down on the cover' 19 likewise, so as to be rigidly secured A top 22 is made of tin for the icecream can,having a central knob 23. A handie 24 is likewise secured to the cover 19 of the bucket, whereby the latter is rotated. An opening is provided in the cover 19 for the insertion of ice or other refrigerant into the space between the bucket and cream-can, arid said opening is closed by the cap 25.

The purpose of the convex bottom of the cream-can is to cheapen and simplify the construction of the cream-can and sleeve and make a water-tight joint with the bottom of the bucket or ice-receptacle and yet to permit the refrigerant to pass under the bottom of the cream-can. To effect this water-tight joint, the diameter of the hole 26 and the bottom of the bucket is greater than the external diameter of the sleeve 11 or the opening in the bottom of the cream-can, as shown in Fig. 6. That enables the convex bottom of the cream-can to bear against the rectangular upper edge of the bottom of the bucket at the hole 26. This whole construction therefore not only creates a water-tight joint, but enables the spindle to be set in the exact center of the cream-can, so that the scraper therein will engage equably all parts of the inner surface of the cream-can.

The worker 27 and scraper 28 are carried by a pair of divergently-extending

arms

29 and 30, respectively, formed, preferably, of one piece of metal bent to form the eye 31. There are two sets of these arms and eyes, the eye below fitting about the sleeve 16 and the eye above about the upper end of the spindle. A pin 32 extends through the upper eye and the spindle to lock the scraper and Worker on the spindle in order that they may be held stationary by the spindle while 'acts as a'scraper for the bottom. 28 is preferably formed of a piece of wood the cream-can and ice-receptacle are rotated by means of the handle 24. The Worker 27 is formed of a plate of metal riveted at each end to the arms 29 of the supports and provided with large holes or perforations 33, through which the ice-cream is forced as the cream is rotated by the rotation of the creamcan, so that the cream is not only forced between the worker and the cream-can, but also through said holes. The lower end of the worker is provided with the extension 34, that conforms with the surface of the bottom and The worker secured in the movable holder 35, which is first placed about the bar 36, secured to the arms 30. After the holder 35 is slipped about the bar 36 the scraper 28 is slipped into the holder. The holder is-prevented from escaping by the extended lip 37 so long as the scraper is in the holder. When the scraper is removed,the holder can be readily removed.

The refrigerant is agitated and distributed by the vertical plate 38, secured to the inner wall or surface of the ice-receptacle 14, as shown in Fig. 1. Since the wall of the icereceptacle is inclined, said plate 38 extends inclined and is provided with a toothed edge, as shown, the edges of the teeth being substantially eqnidistan t from the ice-receptacle. When the vessels are revolved, the ice, water, salt, and other ingredients of the refrigerant by reason of inertia do not revolve as fast as the vessels, and therefore said toothed plate 38 holds the larger pieces of the ice and lets the water and smaller pieces wash the larger pieces, thereby enhancing its freezing power.
