IMPROVEMENT IN COMBINED CHURN AND ICE-CREAM FREEZER.

Specification forming part of Letters Patent No. 214,729, dated April 22, 1879; application filed December '7, 1878.

To all what it may concern.-

Be it known that I, MATTHIAS SWIHART, of Teegarden, in the county of Marshall and and State of Indiana, have invented a new and valuable Improvement in Ice-Cream Freezers and Ohurns; and I do hereby declare that the following is a full, clear, and exact description of the con struction and operation of the saine, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a vertical central section of my ice-cream freezer and churn. Fig. 2 is a perspective view of the crank. Fig. 3 is a top-plan view, partly in section; and Fig. 4 is a plan view of the receiver.

My invention relates to a device which will serve as an ice-cream freezer or a churn, as desired, serving in either capacity in an eflicient and improved manner; and the novelty consists in the construction and arrangement of novel parts, as will be more fully hereinafter set forth in the claim.

In carrying out my invention I employ an outer case or bucket having inwardly-project ing pins at various desired points and a stopcock outlet. The pins on the inner side surfaces serve to hold the churn-case or creamreceiver at a sufficient distance from the outer case to allow a volume of water to intervene when used as a churn, and pounded ice and salt to intervene when used as an ice-cream freezer. A plate in the bottom of the creamreceiverhasjournal-sockets above and belowthe one below to receive a pin in the center of the bottom of the outer tub, and the one above to receive the vertical shaft of the dasher, as shown. This dasher-shaft has radial perfo-- rated arms, and is provided with a square or rectangular socket at its upper end to receive a correspondinglyformed shaft above, which is revolved by proper gearing, belts, or power, said gearing being suitably journaled in a frame upon the cover and outside the outer case. Standards held vertically against the sides of the cream-receiver by circumferential spring-flanges have perforated arms project ing inward toward the center of the dashershaft, and between these arms operate the ra-' dial arms of the dasher. Perforated ears upon the upper outward edge of the cream-receiver receive pins upon the outer case cover, one of which pins serves as a securing device for a handle, said handle serving when the device is used as a freezer.

Referring to the drawings, A represents the outer case or bucket, having inwardly-projecting pins a and a diametrical bottom pin, a, and a water-outlet, A. The pins to a serve to hold a cream-receiver, B, at a sufficient distance from the sides and bottom of tub A, and said receiver is provided in its bottom with a plate, B, having a bottom socket, b, and an inner socket, b. The socket 1) receives the pin a, and the shaft 6 operates in the socket I), which shaft has radial arms 0, perforated at c, as shown.

D represents the vertical standards, having perforated arms d, arranged as shown, and they are held securely against the inner sides of the cream-receiver by circumferential springs D. To prevent any possibility of these standards rotating, lugs may be cast upon the inner sides of the receiver.

The upper end of the shaft ,0 has a rectangular socket, 00, which receives a correspondingly-formed portion, :0, of a revolving shaft, E, suitably journaled in a frame, 1?, upon the cover G of the outer bucket, A. This shaft E is revolved by a beveled gear, E E and crank e, as shown, or other proper power, and equivalent mechanical means may be employed without departing from the principle of my invention.

The cover Gr is formed of two semicircular parts, one of which, g, has a pin, g which operates in a perforated ear, 0 upon the creamreceiver B, and the other half of the cover has a pin, 9 which not only operates in another perforated ear, 0, but is also a securing device for a handle, H, as shown, jaws h of which embrace the dasher-shaft.

When used as a churn, the space around the cream-receiver is filled with cold water, and the crank e is turned to operate the dasher, and thus agitate the cream. When used as a freezer, the space around the cream-receiver is filledwith broken ice and salt, and the handle H is rocked back and forth to turn the cream-receiver in its bed of freezing material, the hooks which secure the cover to the tub or body being first loosened.

The handle H is secured to the cover, and the latter is connected to the creanrreceiver by'a key or pin, 9 passed through the handle H, cover G, and eye 0 and a pin, g passing through a second eye, 0

What I claim as new, and desire to secure by Letters Patent, is-

The interchangeable churn and ice-cream freezer, consisting, essentially, of the receiver B b'b, ears 0 standards D d, springs D, cover Gr, connections 9 g 9 and a suitable dasher capable of being rotated, as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

MATTHIAS SWIHART.
