IMPROVEMENT IN ICE-CREAM FREEZERS.

Specification forming part of Letters Patent No. 181,972, dated September 5, 1876; application filed July 10, 1876.

To all whom it may concern: Be it known that I, CHARLES W. PAGKER, of Philadelphia, Pennsylvania, have invented certain Improvements in IceCream Freezers, of which the following is a specification z The object of my invent-ion isto so construct a driving device for, and so combine it with, an ice-cream freezer, that the freezingvessel and its adjuncts can be readily detached from, and as readily connected to, the said .-driving device without manipulating the coupling, and so that no provision for securing the said vessel is required, a further object of my invention being the raising of the lid of the freezer without moving it away from the driving appliances.

In the accompanying drawing, Figure lis a side view, partly in section, of an ice-cream freezer and driving appliances; Fig. 2, a perspective view of the coupling device, and Fig. 3 a modified form of coupling.

rlhe freezer consists of the exterior vessel A containing the icc, the inner vessel B for containing the cream, a shaft, D, adapted to bear-v ings on thel lid of the vessel A, and bevelwheels b b1, through which motion is communicatedto the vessel B from the driving device, all of which parts -are common to other freezers.

The vessel A rests on a base, E, to which is secured a standard, F, having two bearings, ff, for a horizontal shaft, G, carrying a fly-v wheel, H, one end of the shaft being provided with a suitable handle, I, and the other end with a clutch, J, consisting of a lever with two arms, m and n, the former being provided with a pin, p, and the latter with a curved recess, q. A precisely similar clutch-lever, J',

once withdrawn from all connection with the driving applianceswithout resorting to any preliminary manipulation of the coupling, and can be as easily adjusted, so that its shaft D shall be in gear with the driving-shaft G. It will also be seen that the clutches are such that the vessel A of the freezer cannot be distnrbed by the turning of the shaft G; hence there is no necessity for making any provision for the securing of the said vessel to the base.

It is not essential that the clutch-levers should be constructed precisely as shown in Fig. 2. Oneof the levers, for instance, may have two curved recesses, and the other have two pins, as shown in Fig. 3; but I prefer the plan shown in Fig. 2, partly for the reason that one pattern onlyis required for both levers, but principally because it permits the.

raising of the lid of the freezer without movl zontal driving-shaft Gr, and a freezer, A, with horizontal shaft D, arranged in line with the driving-shaft, in combination with a clutching device constructed, substantially as described,

for permitting the Withdrawal and replacing of the freezer Without manipulating the coupling.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. l

CHARLES W. PAGKER.
