QGOLING RACK Application filed pril 1., 1929. Serial No. 351,673.
rI`his linvention relates to means for cooling and displaying gelatin desserts initially made from heated gelatin mixtures, and has for its primary objects the provision of racks each to support a plurality of individual molds in such manner that the heat from v their contents may be quickly radiated therefrom and dissipated, and that may be stacked one rack upon another within a refrigerator to permit air currents to move laterally thereu between but not therethrough.
The invention is described in reference to the accompanying drawing, in which- Fig. .1, is a front elevation of a refrigerator with my invention applied thereto;
1 Fig. 2, an end relevation` of two racks, one
upon the other;
Fig. 3, a top plan view of a rack;
p Fig. 4, a vertical section on the line 4 4 in Fig. 3; and
Fig. 5, a vertical section on the line 5 5 in Fig. 2. y
Like characters of reference indicate like parts throughout the several views in the drawing.
vI take a flat plate 10, preferably of aluminum for high heat conductivity and form a plurality of holes 11 therethrough, here shown as twelve in number. The holes 11 are made to receive the cups or molds 13 therein with a tight lit. These molds 13 have the outer sides of their wallk inclined outwardly so that when the molds are placed in the holes 11, they will contact the plate 10 on a circumferential line substantially midway up their sides, the contour of the molds 13 conforming to the shape of the holes l1 so that there is no opening ,therebetween and the metal plate 10 is in physical contact around the molds.
At each end of the plate 10, is a handle 14: to permit handling the plates 10 in safety. At each corner of the plate 10, is a depression 15, Fig. 5, from the top face, and a post 16 having a neck 17 reduced in diameter from that of the post is placed up against the under side of each depression 15 to have the neck 17 passed through a hole in the :depression and peened over on the upper face thereof so as to secure the post 16 to the plate 10. The
top of the peened over neck 17 is below the surface of the plate 10 so that when a plate 10 is placed over the plate 10, Figs. 1 and 2, the posts 16' of the upper plate may rest by their ends in the depressions of the plates below, as a means -of preventing the upper plate from slipping oli' from above the lower p ate.
Now I place a plurality of these plates, here shown as four, stacked one above the other, in a refrigerator compartment 18, Fig. 1, so that air may circulate freely upwardly along the sides. Since thewarm air tends to rise in the compartment, cold air is drawn in at the bottom and laterally across between each adjacent pair of plates, and the plates 10, 10 serve as radiating ins for the molds so as to tend to dissipate heat from the centers of the molds, while the moving currents of air tend to conduct heat away from the tops and bottoms of the molds, thereby insuring( a quick and uniform transfer of the heat from the molds.
1. A cooling plate having a plurality of receptacle receiving holes therethrough and depressionsv from the upper surface spaced therearound near the outer edges, a post under each of said depressions, a neck projecting from each post through said plate into the respective depression, and a head peened over from the top of said neck within said-depression andhaving its upper surface below the level of the top surface of said plate.
2. In a gelatin cooling device, a plurality of plates having holes therethrough and posts spacing said plates one above the other, said plates having depressions in their top corners and bosses thereunder, said posts being fixed to depend from said bosses of one plate and rest in said depressions of the next below. In testimony whereof I aliix my signature.
