IMPROVEMENT IN ICE-CREAM FREEZERS.
Specication forming part of Letters Patent No. 218,162. dated August 5, 1879; application filed January 21, 1879.
To all 'whom it may concern:
Be it known that I. THOMAS R. OLOUGH, of Medford, State of Massachusetts, have invented Improvements in Ice-Cream Freezers, of which the following is a specification.
This invention relates to that class of utensils known as ice-cream freezers, which are employed to produce congelation of cream, known as ice-crea1n;7 and the invent-ion consists in a vessel or receptacle for the cream formed with both an exterior and interior annular wall, the area inclosed by such inner wall being open at the bottom, but closed at the top by an indented or recessed cap secured thereto and provided with a small airvent to allow the escape of the air as the liquid rises therein, and the space between such inner and outer walls being closed at the bottom, while a cover resting upon the top of the outer wall covers the area thereby inclosed, including such inner Wall and its cover, a dash or breaker being arranged to act against both of the said walls, such dash being stepped or pivoted in the cap of the interior wal1,and its stem, extending up through the cover se' cured to such outer wall, is stepped in the cover of the ice-receptacle, rotation being imparted to the cream-receptacle by means of a crank-shaft, carrying a gear, which meshes into a similar gear secured upon the cover of the cream-receptacle, an `overflow-vent being provided in the wall of the ice-receptacle in a lower plane than the air-veut in the cap of the interior wall of the cream-receptacle, in order that, while the liquid may rise coincidently in such interior tube and the ice-vessel to the height of the vent in the latter, it may not overflow into the cream receptacle or chamber.
The accompanying drawing is a vertical longitudinal section taken through the axis of the cream and ice vessels, and also of the driving-shaft and its crank, and showing the icereceptacle, the cream receptacle, and the breaker or dash, all in their proper relative positions for use.
In said drawing, A A represent the walls of the ice-receptacle 5 B is the bottom thereof, and C the cover, which is the usual circular disk or covering. D D are the exterior walls of the cream-receptacle; E E is the bottom, and F F the interior walls, thereof. Gr Gr are the wings of the dash or breaker. H H is the horizontal bar through which the wings are connected with the central stem I. The lower end of this stem terminates in a pivot, which is stepped in cap J of the interior walls F F.
The lower ends of the wings of the dash are united, for mutual support, by a bar which curves round the wall F, as is shown by dotted lines.
e is a step secured to bottom B, and the cream-receptacle is pivoted therein by a pivot n the cross-bars d, which extend and are secured across the space within walls F, and allow a free circulation in said space of the freezing-liquid, which is interposed between the ice and cream vessels. K K is the cover of the cream-vessel, fitting closely thereon, and interlocked therewith by the lug k, secured to the cover, and inserted in loop l, secured to wall D, whereby the rotation of the cover insnres that of the receptacle itself. o c show a concentric miter-gear secured to cover K. f is a similar gear meshing into gear c, and secured upon shaft g, by whichit is, through the agency of crank z', rotated. The shaft g is journaled in lugs formed on plate 71., which latter is secured to cover G, in which is cut a suitable space for gear f and shaft g.
The water-overflow vent fm in wall A of the ice-vessel, being arranged in a lower horizontal plane than the air-vent n, will prevent the liquid from rising to a height that would allow it to flow through vent a into the creamvessel. The stem l, which is square at its upper end, lits a corresponding hole in plate h, and is thereby held from rotating.
When the cream-receptacle is rotated by means of crank i, shaft g, and gears c f, as described, the breaker G G remaining stationary, its Scrapers a b will constantly remove the congealed cream from the respective walls D F, thereby facilitating the freezing process.
When the freezer is in use, the liquefied contents in receptacle A may rise -to the height of the drain-duct m, and will, of course, rise to the same height in the innerwalls, F, thereby causing the con gealing process to proceed both upon the inner and outer surfaces of the cream so exposed. Besides this, the interior tube or walls, F, prevent that neutral axis in the cream, which, in freezers with slugie walls, is not disturbed or brought in oonin plate h, cover K, with its gear c, and intertact with the freezing-surfaces of the vessel. locked with vessel D, and the crank-shaft g, In the present state ofthe art it will be obwith its gear f, all substantially as specified. vious to those ot' ordinary skill therein that by 2. In a cream-freezer, the combination, with a suitable arrangement of driving devices ice-vessel A, having vent m, 0f the double-Wall either the cream-receptacle or the dash, or creanrvessel D F, provided with the cap J, both, may be rotated, as may be deemed pret'- having vent n, substantially as specified. erable.
