B. HARIBERT,l ICE-CREAM FREEZER.
No.`174,67 3. Patented 2M1'.a.rc1114,1876.1v

BETTLE HARBERT, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN ICE-CREAM FREEZERS.
Specification forming part of Letters Patent No. l7-L673, dated March 14, 1876; application filed February 23 i876.
To all lwhom @t may concern Be it known that I, BETTLE HARBERT, of the city of Philadelphia, in the State ot' Penns 7lvania have invented anew and uset'ul Ilu- 7 provement in Freezers for Ice-Cream, which improvement is Jfully set forth in the annexed specification, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view ot' the Vcan and my invention applied, the front portion ot the tulo or ice-holder being cut away in order to expose the Jformer. Figs. 2 and 8 are detached portions, enlarged, oi' Fig. 1.
The object of my invention is to keep the can securely down on the bottom of the tub, or preventing it from rising or being buoyed upward by the water ot' the melting ice which surrounds it during the latter portion of the operation ot' freezing and smoothing the cream, and also during the retailing ot' the ice-cream from the cana result ot importance, not only in holding` the can irinly down in its proper position, but in avoiding the necessity of frequently drawing ott' the ice-cold water, and consequently losing its refrigerating effect, and requiring the substitution ot' more ice and salt.
rEhe nature of my invention consists in the combination, with the two opposite sides of the inner upper portion of the tub, oi' respective stationary supports, provided each with an elastic cushion or spring, which will bear against an adjustable ratchet-bar, provided` with two curved and grooved arms, which will it or grasp the circular rim which projects around the upper end ofthe can below the removable cover ot' the latter, and pressed against by the spring or cushion in its respective support, while the ratchet-bar is prevented by its appropriate tooth from slipping upward in its place in an appropriate openin g provided with a stationary catch, and thus the two described holders, acting simultaneously on the two opposite sides oi' the rim of the can, keep the latter firmly down in its proper position upon the bottom ofthe tub, as required.
Referring to the drawings, A is the tub 5 B, the can; b', the lid or cover ofthe can, and b the rim around the upper end of the latter and below the lower edge of the former; C C, the two ratchet-bars, and c c their two respective grooved arms; D D, the supports, and d d their respective springs or cushions. The ratchet-bars U are each straight, and can be readily introduced and withdrawn into and out of an oblong opening in the support l), and can be loosely suspended therein by their respective heads c". The upper boundary of the oblong opening in D has a wedge-shaped edge, d, which tits between the ratchet-teeth ofl C, which are inclined at their under side edges, as shown, and -consequently the bar G will easily slip downward in contact with said teeth, but will at the same time be prevented from slipping` upward. rlhe grooved arms c c of C are curved horizontally, so as to grasp the presenting side ot' the rim b" ot the can, when the latter is placed concentrically on the bottom of the tub B, and the ratchet-toothed bar C pressed downward by hand into contact with the said rim, and then by the pressure ot' the spring or elastic cushion d', in co-operation with the appropriate tooth ot' the bar G and the wedge-shaped edge d" ot' the support D, substantially as represented in Fig. 1.
The mode otl applying and using my invention is as follows, viz: The can B containing the cream being placed concentrically in the tub A, and surrounded with broken ice and salt in the usual manner, and then oscillated until the cream has ceased to flow, the operator removes the lid b', introduces the two ratchet-bars G G through the respective open ings in the supports D, and forcing them downward by hand with their backs sliding and' pressing against the spring or cushions d', andtheir ratchet-teeth against the'wedge-shaped holders d", respectively, until the can B'becomes irmlyand rigidly held down on the bottom ot' the tub A, as indicated in Fig. 1. llhe lid b is then reapplied and removed, as occasion may from time to time require the cream to be worked and smoothed in refrigerating, and in retailing it from the can in the ice mid salt used to compensate for the loss ot' its refrigeruting effect upon the cream in the cnn. In time the water of the melting ice and salt will necessarily rise toward the cover or lid of the xed can, mld sufcient portions oi1 the snidwnter must be drawn olf in that ense to prevent its entering` the can.
I claim as my inventiony l. Ilhe combination, in al freezing-tub for icecream, substantially as described, of the supports D D, provided with the springs or cushions d cl', respectively, for giving,r the elastic pressure' upon the lower ends ofthe ratchet-bars U G.
2. The ratchet-bar C, provided with the series of teeth inclined upward, as shown, and the grooved arms c o', curved to (it over the projecting rim b of the can B, substantially ns and for the purpose set forth.
