SPECIFICATION forming part of Letters :Patent No. 553,554, dated January 28, 1896.

Application filed May 22, 1895. Serial No. 550,230. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, WILLIAM H. DE CAMP, a citizen of the United States, residing at Fort Vayne, in the county of Allen, in the State of Indiana, have invented certain new and useful Improvements in a Combined Churn and Ice-Cream Freezer; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw'- ings, which form part of this specification.

My invention relates to'improvements in a combined churn and ice-cream freezer.

The objects of my invention are to produce a convenient and economical machine which can be used both as a common dairy or household churn and a cream-freezer. I atta-in these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical sectional view of the entire machine; and Fig. 2 is a detail partlysectional view of pinion 9, with a section of the wire agitator 10.

Similar iigures refer to similar parts th rou ghout the several views.

1 is a platform or table securelyfastened to and supported by any proper number of legs 1S so as to give the necessary stability' and strength to sustain the other parts of the machine. If desired, the legs can be secured to the floor by screws or bolts through the flanges 35.

31 is a shelf securely fastened to the legs 1S at a sufficient distance beneath the table Q 1 to receive and support the machine thereon, as hereinafter described.

24 is a bed-plate casting resting upon the shelf 31 and rigidly secured to it by any suitable means.

23 is a conical bearing in the casting 24 and in which rests the conical end of a vertical cylindrical rotatable shaft 5, which extends nearly to the top of the .machine7 as hereinafter described.

Rigidly secured to the lower end of the shaft 5, just above its bearing, is a bevel gearwheel 22, and at a proper distance above the gear-wheel is a collar 20, also rigidly secured to the shaft 5. Resting upon the upper side of the collar 20 and sleeved upon 5 is a vertical, hollow, cylindrical, and rotatable metallic shaft 2. At the lower end of the shaft 2 is rigidly secured another bevel gear-wheel 19.

25 and 25 are vertical standards integral with the cast-ing 24, and having at the upper ends boxes in which are journaled the horizontal cylindrical shaft 26. At the outer end of 26 is secured a removable crank'27 and at the inner end is rigidly secured the bevel gear-wheel 21, which meshes on its lower side with the wheel 22 and on its upper side with the wheel 19.

The shaft 2 passes through a perforation in the table 1 and through a suitable box-bearing 17 secured upon the upper surface of said table.. At a suitable distance above the table 1 to admit of free movement there is rigidly secured to the shaft 2 a horizontal, circular, and centrally-perforated metallic plate 36, which will rotate with the shaft 2, as hereinafter stated. From its lower end to the upper surface of the plate 36 the shaft 2 is of uniform diameter; but the part 6 above the plate is conical and extends nearly to the top of the churn-body 3.

Resting upon the plate 36 and supported by it is a metallic cylindrical flat-bottomed churn-body 3 having in its diametrical center a conical thimble 16 corresponding to the perforated plate 36 and which surrounds the shaft 2 and is open at both ends. rllhis thimble 16 extends nearly to the top of the churn 3 and is integral with its bottom so as to securely retain the contents within the churn when charged.

Above the upper end of the thimble 16 a horizontal spur-geared wheel S is removably secured to the upper end of the shaft 2 so as to revolve with the shaft.

Above the wheel 8 upon the shaft 5, and removably secured to it, is a horizontal lever '7, with arms of unequal length extending from its attachments with the shaft 5. At the end of the longer arm of 7 is attached, obliquely to the radius of 5, a scraper 11, with its outer edge just in contact with the interior sides of the churn 3. To the shorter arm of 74 is removably attached the spur-pinion 9 by a bolt and washer 413, as shown in Fig. 1.

In the pinion 9 are perforations for the wires, which collectively form the agitator 10 IOO and which are attached and arranged as shown in the detail View, Fig. 2. The pinion 9 is geared with the spur-wheel S, and revolves freely upon its journal 43.

The churn-body 3 has a removable lid et, which can be secured by suitable clamps 15.

13 is a removable ice-tub having suitable handles 14 and in its centera concentric opening for the plate 36 and the churn 12 is an interior concentric jacket forming the circumference of the said opening, and is made of non-corrosive metal and integral with the bottom 37 of the ice-tub. This jacket is about one-third in height of the outer wall of the tub, and both the plate 36 and the churn 3 fit closely within the opening, but sufficiently loose to permit Vboth plate and churn to rotate freely with the shaft 2. By this construction an annular space for the freezingr mixture surrounding the churn and permitting contact with it is formed.

A motor attachment for operating the ma.- chine is shown in Fig. 1, which may be attached and thereby much man ual labor bedispensed with, which I describe as follows: Ver` tical upright metallic standards 42 are rigidly secured to the casting 2l at one side of the standards 25. Upon the standards- 42 is mounted a horizontal shaft 41, at the outer:

end of which is attached a suitableioperating crank 33, and at the other extremity are mounted upon said shaft a spur-geared wheel 38 and a coiled steel spring 29, having its upper end rigidly secured to a cross-bar rigidly attached to the standards 42. A rotatable shaft 40 is also mounted upon the standards 12, upon which is a pinion-wheel 39,V which meshes into 38, and also a pinion 30, which meshes into the spur-wheel 28, mounted upon the shaft 26. By means of the crank 33 the spring 29 can be wound up like a clock-spring, and its expansive force will producea rotary motion to the churn through the drivingwheel 21.

Other suitable methods of applying motive power will be suggested to mechanics.

The method of operating my invention is as follows: To use as a churn the milk or cream is placed in the churn 3 Without filling it quite to the upper end of the sleeve 16. The lid 4 is secured in place, and by turning the crank 27 motion is 1 communicated to the shafts 2 and 5. It is obvious that the shafts will revolve in opposite directions -andthat the agitator 10 will revolve about the shaft 2 and at the same time rotate upon its own axis, while the scraper 1l will revolve upon the shaft 5. The churn 3, mounted upon the plate 36, will also revolve, and by these op posite motions the contents of the churn will D the contents toward the agitator 10.

The method of removing the contents will be so readily understood as not to need a detailed description.

For use as a freezer the material is placed in the churn and the space between 3 and 13 filled with the freezing mixture, as in other freezers. The rotatory motion of the churn brings its sides in immediate contact with the freezing mixture at all points, while the cream or other' contents to Abe frozen are thoroughly stirred by the agitator lOand the scraper 11.

Having thus described my invention, what I claim, and desire to secure by Letters Pat ent, is-
