CONFECTlONERS COOLER.
SPECIFICATION forming part of Letters Patent No. 758,823, dated May 3, 1904.
Application filed November 2l, 1903. Serial Nn. 82,114. (No model.)
Be it known that l, GEORGE S. COLLUM, a citizen of the United States, residing' at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Confectioners Coolers, of which the following' is a specification.
This invention relates to a device for chilling and hardening' hot candy and confections.
The object of this invention is to provide a very simple, cheap. and etiicient water-chilled cooler.
The embodiment of the invention illustrated has two similar flat metallic plates held apart, so that there is a space between them, by thin packing-strips near the edg'es and secured together by screws, the top plate having' a polished upper surface and the bottom plate having' openings for the inflow and outflow of water which is circulated between the plates inside of the packingfor carrying off the heat.
Figure l of the accompanying' drawings shows a plan of the cooler with a portion of the top plate broken olf. Fig. 2 shows a longitudinal section of the cooler. Fig. 3 shows an end view.
The top plate l and bottom plate 2 are preferably made of steel and substantially the same shape, size, and thickness. The upper surface of the top plate is made flat and is highly polished to prevent as much as possible the sticking' of candy or confections to the plate. The bottom plate has openings 3 near one end adapted to be connected by pipes with a water-supply and opening's e near the other end adapted to be connected with a waste-pipe. Near theiredg'es both plates are drilled and the perforations in the top plate are tapped with threads for receiving' the screws 5, which are screwed in from the bottom for fastening the plates together. Separating the two plates and forming waterproofl joints around the edg'es are packing-strips 6. These strips, which may be made of rubber or other suitable packing material, are preferably halved together at the ends, so as to form a wall of uniform thickness between the edges of the plates. This paclv'ing may be formed of a single strip along each edge or two strips may be used along' each edge, one lying' outside and one inside of the screws used to fasten the plates together. It is preferred that grooves 7 be made in the inner faces near the edges of the plates, so that when the plates are drawn together by the fastening-screws the packing will swell into the grooves and insure water-tight joints. If it is desired, a row of perforations maybe drilled through the center of the plates. These perforations in the top plate are tapped and screws 8 are turned through the bottom pla-te into these tapped perforations. Packingwashers 9 are placed around these screws between the plates in order to prevent lealv'age. These screws prevent the plates from swelling or buckling' at the center.
The cooler may be placed on common horses or any convenient support. Hot candy is poured or hot con fections are placed upon the upper surface of the top plate. rater is admittcd under pressure through the inlet-openings at one end of the bottom plate, and after filling the thin space between the two plates flows through the outlet-openings near the other end of the bottom plate to the waste. The water is distributed from one end to the other, so that the top plate is cooled evenly and the candy or confections at all localities on it are cooled uniformly.
These plates are very simple to make and easy to fasten together so that they will not leak. The top plate may be quickly removed from the bottom plate for the purpose of cleaning', polishing', or adjusting' and is easily made water-tight when replaced. The rectangular plates may be rolled to shape or they maybe cast and the top plate polished in any common manner. Butlittle machining' is necessary. fhile both plates are practically alike, the bottom plate need not be finished as highly as the top plate.
This cooler occupies but little space, it is light in weight, it is easily placed upon legs or trestles, it is conveniently handled and transported, and it is eilicient, although requiring' but a small quantity of water.
The invention claimed is* 1. A confectionery-cooler consisting' of two flat metallic plates of uniform thickness arranged parallel with each other, packing'- stri ps placed near the edges between the plates IOO and holding them slightly separated, means fastening one plate to the other and causing the packing-strips to make water-tight joints with the adjacent surfaces of the plates, and means for the inflow and outflow of water whereby a thin iilm of water may be caused to flow between the plates, substantially as specified. f
2. A confectionery-cooler consisting of two fiat metallic plates of uniform thickness arranged parallel with each other, the bottom plate having openings near one end adapted to be connected with a water-supply and openings near the other end adapted -to be connected with a waste-pipe, packingstrips placed near the edges between the plates and holding them slightly separated, and means fastening one plate to the other and causing the packing-strips to make water-tight joints with the adjacent surfaces of the plates, substantially as specified.
3. A confectionery-cooler consisting of two fiat metallic plates of uniform thickness arranged parallel with each other, packingstrips placed near the edges between the plates and holding them slightly separated, screws extending through perforations in the plates for holding them together and causing the packing-strips to make water-tight joints with the adjacent surfaces of the plates, and openings for the inflow and outiiow of water whereby a thin film of water may be caused to flow between the plates, substantially as speciiied.
1f. A confectionery-cooler consisting of two fiat metallic plates of uniform thickness arranged parallel with each other, screws eX- tending through perforations in the plates for holding' them together, and packing-strips located inside and outside of the screws between the plates and holding them slightly separated and forming water-tight joints with the adjan cent surfaces of the plates, substantially as specified.
5. A confectionery-cooler consisting of two flat metallic plates of uniform thickness arranged parallel with each other, screws eX- tending through perforations in the plates for holding them together near the edges and along the center, and packing-strips located between the plates near the edge screws and about the center screws for holding the plates slightly separated and forming water-tight joints with the adjacent surfaces of the plates, substantially as speciiied.
