SIEECIFICATIONV forming part of Letters Patent No. 249,384, dated November 8, 1881.

Application filed September 24, 1881. (No model.)

To all whom it may concern:

Be it known that I, HENRY MORRIS, a citizen of the United States, residing at Bhiladelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ice-Cream Freezers; and I do hereby declare the following to and exact description of the invention, such as will enable others skilled in the -art to which it appertains to make and use the same, reference being had to the accompanying drawings,aud to the letters orgures of refer ence marked thereon,which form a partof this specification.

This invention relates to implements for freezing ice-cream and similar articles; and it consists in certain improvementsin the con4 struction of the` same, as herein shown and described.

In the accompanying drawings, forming a part of this specification, Figure l represents a plan view of an ice-cream freezer having my Fig. 2 isa vertical central section of the same.

In the said drawings,A designates the outer vessel or casing of the` implement, and B the can which is placed therein, suitable space, C, being left for the ice betweenV the can and the casing, as shown. The can is provided with a removable cover,D, secured thereto in any suitable manner. To the under sideof said cover, at the center,is made fast a gear-wheel, E, and directly over the same, and to the upper side of the cover, is fastened a beveled gear, F. The can has formed on'the bottom, which fits in a socket, c, fixed to or made in the bottom ofthe outer vessel, A, so that the can has a pivotal bearing and maybe readily rotated Within said vessel. The projection a is hollow, and forms a socket to receive the end of a vertical shaft, G, placed in the can and at the center thereof, said shaft'extending upward through an aper-` ture in the cover D and gear-Wheels E and F. The upper end, e, of the shaftGis square, and enters a corresponding aperture in the crosspiece H at the top of the vessel A, so that the shaft is held stationary when the can B is rotated. The said cross-piece, which sustains being communicated through gearing 1,E, and

F to the can B, the latter is also rotated. 4'

Under the gear-wheel E, and extending from.

the shaft G, to which it is fastened', is an arm,

g, and another horizontal arm, h, extends from said shaft at its lower end, as shown.

The stirrer I is held in a vertical position by the arms g and It, being pivoted at t'- to the said arms, and is actuated by a gear-Wheel, k, which engages with the gear-wheel E. `Ihe last-named wheel, being larger'than wheel 7c, is usually made with an odd number of teeth, and the wheel k with an even number of teeth, so that each stroke of the stirrer I with reference tothe contents of the can is different 'from the last preceding stroke. Y

The cross-piece H has at one end a detachable hingeconnecti'on with Athe top ofthe vessel A by means of a rung, my, which rests in a seat, a, secured to the top of the vessel, as shown, and provided With a vertical part, Z, extending upward, against which the cross-piece may rest y when it is raised from thevessel, as indicated in the drawings in Fig. 2. The opposite end of the cross-piece, when in place, rests in a seat, o,iixed to the top of the casing, asshown.

In operation motion is imparted to the can B, as above stated, through gearing d, E, and

F, the shalt G remaining stationary as the cany is rotated; and the gear-wheel la, engaging with gear E, causes the stirrer torotate rapidly in a direction opposite to that of the movement of the can, the movement ot' the stirrer being such as to drive the cream nearest to the ice (being the first to con geal) toward the center of the can, so that the whole contents is rapidly and thoroughly frozen.

I claim as my invention- Il. In an ice-cream freezer, the revolving can B, provided with the cover D, having secured lthereto the bevel-gear F, the non-revolving central shaft, G, former of which carries a gear-wheel, k, which having the arms g and h, the

as and for the purpose set forth.

`5 2. In an ice-cream freezer, the cross-head H,

carrying the gear d and arranged to receive the square-head of the uonrevo1ving central shaft, G, in combination with the can B, cover D, and attached gear-wheel F, and the gears E 7c, arranged to give a rotary motion to the 1o' stirrer'I, substantially as set forth.

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

HENRY MORRIS. e
