Inventor UNITED STATES PATENT OFFIo DAVID BOYLE, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO HIMSELF AND JOHN W. PEARSON, OF SAME PLACE.
IMPROVEMENT IN ICE-MACHINES.
Specification forming part of Letters Patent No. 128,448, dated J unc 25, 1872.
SPECIFICATION.
To all whom it may concern:
Be it known that I, DAVID BOYLE, of the city and county of San Francisco, State of California, have invented a new and useful Improvement in Ice-Machines; and I do hereby declare the following description and accompanying drawing are suflicient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention without further invention or experiment.
My improvement relates to various parts of ice-making or freezing machines, particularly to that class in which the vaporization of a volatile fluid is used for producing the required degree of cold.
My improvements are fully described and explainedin the following description, in which reference is made to accompanying drawing forming a part of this specification, in which- Figure 1 is a perspective view. Fig. 2 is an elevation of the refrigerator. Fig.3 is a plan of the refrigerator. Figs. 4 and 5 are sections of the distributer. Fig. 6 is a section of one of the chambers of the refrigerator.
A represents a tank, inside of which are placed the coils with their freezing surfaces. The tank A, when in use, will be surrounded by some non-conducting substance. B B B B are vertical partitions, which are constructed of the coils above mentioned. These coils are made of tubes 6, having their outside sectional outline in the form of a parallelogram, while the passage through them is circular, or oblong with circular corners, as shown, Figs. 5 and 6, thus giving strength to resist fracture from pressure within while offering a smooth plane surface externally for the ice to form on. These tubes are cut to the proper lengths to form the partitions B, and are united together horizontally, having mitered soldered returnjoints, so that -each partition is formed of a continuous coil extending almost from the bottom to the top of the tank and almost from one side to the other of it. These tubes, when thus united together, form a partition or slab having a smooth even surface upon both sides, upon which the ice is to be frozen. The number and length of these partitions will be varied according to the size of the machine.
Entirely surrounding the edge of each of the partitions I place a continuous tube, C, and at intervals along the length of the partitions I connect the bottom and top horizontal tubes by means of the vertical hollow tubes or ribs 01, upon each side of the partition. These vertical tubes or ribs d are made triangular in form, as shown, and they communicate at both ends with the tube C. Short tubes 6 serve to connect the surrounding tubes C of the partitions, so as to give a free circulation around each of them for the purpose hereinafter mentioned. Outside of the tank A is an exhaust and force pump, F, located conveniently with reference to the work it is to perform, and suitably placed with reference to the pump and freezing-tank A is the condensing-tank G. The condensing-coil S is formed of any suitable length or number of tubes to provide sufiicient radiating surface. The vessel H, which is attached to the lower end of the condensing-coil S, forms areservoir to contain the liquid which is to be vaporized for the purpose of producing the cold. A tube, 1', leads from the bottom of the reservoir H to a distributer at the side of the tank A, and from this distributor as many tubes or pipes K radiate, and are connected to the topmost end oi the pipe forming the coils B, as there are coils in the tank A. This distributer or regulating valve consists of a cylinder,
j, having a solid piston, l, with its lower end turned off conical to fit a seat in the bottom of the cylinder over the mouth of the inletpipe. The piston is operated the same as in a globe-valve by a screw on the rod and studing-box. The diameter of the opening in the lower end of the cylinder j is greater than at the upper end, a square shoulder being formed about the middle of the cylinder. A tube or lining, Z, ismade to fit in this lower enlarged end and slip up until it rests against the shoulder, and thus give a hole of equal diameter passing entirely through the cylinder. In the present instance this tube is represented as being attached to or a part of the bottom of the cylinder, but the two can be made separate,if desired. Vertical slots 0 are made in the lining Z, commencing at the bottom, and their outer edges are beveled'off 'so as to provide a channel or groove between the lining and tube,
to which communication is had through the slots. Holes are made through the cylinder opposite each of these channels to form the exit of the fluid discharged through the slots into the channels, and into these holes the radiating or distributing pipes are secured. When the conical head of the piston is screwed tight against its seat no liquid can enter 5 but as it is gradually raised each slot will be equally uncovered, and thus each distributing-pipe will inevitably receive the same supply of liquid. 1? is the main pipe, which leads to the exhaust side of the pump F. This pipe is connected with the lower end of the pipe, forming the coil partitions B, by the short connecting-tubes q. Upon the opposite or com pression side of the pump is a pipe, B, which leads into the upper end of the condensingcoil S. The pipes P and B are connected by the two pipes s and t, which pass around upon opposite sides of the pump, and stopcocks are suitably arranged, so as to reverse the action of the pump by putting the ex haust -port of the pump in communication with the top of the condensing-coil, and the compression outlet of the pump in communication with the freezing-coils B. Secured to the side of the tank A is an. overflow-pipe, U, which communicates with the interior of the tank below the surface of the water. This pipe is bent upward and its end then bent forward in the form of a siphon, so that it will keep the water on the inside of the tank standing level with the top of the coils. Connected with the pipe or tube i is a glass): tube, V, which serves as a liquid gauge. This tube is, in the present instance, repre sented as being inside of the condensingchamber G, but in most cases I shall place it upon the outside and surround it with a large glass tube, which shall form the inlet through which the supply of cooling-water is passed into the condensing-chamber.
The operation of my freezing-machine is as follows: The tank A is.filled with water so as to entirely submerge the coils, the overflow-pipe causing it to stand upon a-level with the top of the coils and below the upper horizontal portion of the surrounding tubes 0. The distributing-valveis then opened to allow a flow of volatile liquid into the freezing-coils B. The pump F is then started to exhaust the vapor or gas formed in the coils B and to compress it into liquid form again in the condensing-coil S. This operation goes on continuously until the heat ex.- t-racted by the vaporization of the volatile fluid from the water in which the coils B are compression liberates heat and thaws the ice' off their surfaces. The tubes 0 are then filled with water, which detaches the ice from them, allowing it'to be removed from the tank.
By this means Iconstruct a simple and effective freezing-machine, in which the work of making ice can be accomplished with little trouble, my improvements being of great value in enabling the work to be done successfully.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The tubes b, having their outside sectional outline in the form of a parallelogram, while the passage through them is made with circular corners, for the purpose specified.
2. Thetube O, entirely surrounding the coils or partitions B,--substantially as and for the purpose above described.
3. The triangular dividingribs 01, for the purpose specified.
4. The dividing-ribs d, arranged to communicate with the surrounding tube 0 both above and below the partitions, substantially as and forthe purpose above described.
5. In combination with the condensing-coil, the glass-tube or liquid-gauge V, when placed so as to be continually surrounded by water, substantially as and for the purpose above described.
6. The perforated cylinder j, with its piston l, in combination with the bottom on and slotted tube a, substantially as and for the purpose above described.
7. In combination with the freezing-tank A, the overflow-pipe U, substantially as and for the purpose above described.
8. An ice-ma-kin g or freezing machine, consisting of the tank A, partitions B with their surrounding tubes 0, overflow pipe U, distributer j, connecting-pipes P R, and reversing-pipes s t with their cocks, pump F, and
condensing chamber G, all constructed and arranged to operate substantially as and for the purpose above described.
In witness whereof I have hereunto set my hand and seal.
