"TF I 1 UNITED STATES PATENT OFFICE.
LEWIS PURFURST, OF BOSTON, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO STANDARD HYGIENIC COOLER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
LIQUID-COOLING COIL.
To all whom it may concern:
Be it known that I, LEWIS PURFURST, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Liquid-Cooling.Coils, of which the following is a specification.
My present invention relates to certain new and useful improvements in liquid cooling coils of the type usually employed to cool beer, water, carbonated waters and the like, and the chief purpose of the invention is to provide a coil that may be easily, quickly, and thoroughly cleaned.
It is a well known fact that the cooling coils now in general use in bar rooms and at soda fountains, and through which beer and carbonated waters are conveyed, soon become foul and must therefore be cleansed regularly and at frequent intervals in order to insure the purity of the liquid drawn therethrough. The coils with which I am familiar and such as are now in general use, are not only difficult and expensive to clean, but the initial cost is considerable as compared to their life, and for these as well as other reasons they are objectionable.
It is the purpose of the present invention to provide a cooling coil that will not only be simple and inexpensive in construction but one that may be easily and quickly taken apart and cleansed and as quickly reassembled, the construction of the various parts being such that the cleaning may be readily done with a brush that can be passed through the various parts of the coil when the cooler is dismantled.
Briefly and generally stated the invention comprises a liquid cooler consisting of opposed members or side blocks each having a plurality of substantially U-shaped conduits formed therein and a series of interposed tubes connecting said conduits in such a manner as to provide a continuous circuitous passage, means being provided to draw the said opposed members toward each other and against the ends of the interposed tubes to form liquid tight joints at the points where the said tubes contact with the said opposed members.
More specifically stated the invention comprises the features of construction and general organization and arrangement of parts shown in the accompanying drawing and Specification of Letters Patent.
Application filed November 16, 1909.
Patented Aug. 23, 1910.
Serial No. 528,413.
described in detail in the following specification.
In the accompanying sheet of drawing which is illustrative of a preferred embodiment of the invention, Figure 1, is an elevation partly in section of a complete liquid cooling coil embodying the features of my invention. Fig. 2, is a central transverse section, and Fig. 3, is a perspective view of the series of tubes employed in the construction and showing the manner in which they are held in nested or cage-like form.
Referring to the accompanying drawing the reference numerals 1 and 2, designaterespectively two opposed members or side blocks preferably made 'of cast metal and each of which has formed therein during the process of casting, a plurality of returnbend or substantially U-shaped conduits 3, the face of each block being counterbored as shown around the entrance and exit ends of each of the legs of said conduits 3, to form seats for the soft metal, leather or other packing rings 4. It will be seen that the return-bend conduits 3, in the opposed side blocks 1 and 2, are positioned so that the exit end of one conduit in one block will be directly opposite the inlet end of a conduit in the opposed block. Interposed between the two side blocks 1 and 2, are a series of tubes 5, the opposite ends of which are inserted in the counterbored portions of said blocks and bear directly against the packing rings 4:, in order to provide a liquid-tight joint. The series of pipes 5, are preferably maintained in proper spaced relation one with the other corresponding to the spaced distance between the several conduits 3, so that the whole series may be handled as a single unit and this materially assists in assembling and dismantling the cooler. One manner of so maintaining the said pipes is to pass them individually through regularly spaced openings in one or more plates 6, ar-
When it is desired to clean the various parts of the cooler it is necessary only to unscrew the wing nuts sufiiciently to enable the tie-rods to be removed from the slots in the opposed members whereupon said members may be withdrawn from engagement with the series of pipes and a suitable brush may then be passed through the said pipes as well as the U-shaped conduits 3.
When in use the cooler is placed in a suitable tank or vessel and ice is placed upon or packed around the pipes 5 so that as the liquid passes through the coil it will become thoroughly cooled.
The inlet and outlet for the coil may be connected in any suitable manner. In the present instance I have shown the inlet pipe 10, thatleads from the source of supply as having a threaded connection with the side member2, and the outlet pipe 12, as leading from the side member 1. Of course the inlet and outlet pipes may be connected in any other suitable way without departing from the spirit of the invention.
" It will be obvious that the side blocks or opposed members, as well as the series of pipes, may be made of any length or dimensions to meet the demands in any particular case; and it will be obvious also that in view of the particular construction of the cooler, one cooler may be superposed upon another in order to obtain a greater length of coil in a given space. V
I do not wish to be understood as limiting myself to the precise construction and ar rangement of parts as herein shown and described, but reserve to myself the right to any and all changes or modifications as may come within the scope of the appended claims.
What I claim is:.
1. A liquid cooler comprising a group of straight tubes of equal length arranged geometrically parallel with each other, and with their adjacent ends in the same right line, spacing members which maintain the tubes in the relation aforesaid which spacing members are located between the sides of the group, a head block on each side of said group of tubes, said head block having U-shaped conduits formed therein, the ends of which conduits are all on the same face of the head, are spaced apart the same distances as are the tubes of the group and are enlarged to form sockets of the same diameter as the external diameter of the ends of the tubes and into which sockets the ends of the tubes project, shoulders at the bottoms of said sockets, packing rings of less thickness thanthe depth of the sockets resting on said shoulders, and means for clamping said heads to the sides of said group of tubes and clamping the packing between the shoulders and the ends of the respective tubes.
2. A liquid cooler comprising a group of straight tubes of equal length arranged geometrically parallel with each other and with their adjacent ends in the same right line, spacing members which maintain the tubes in the relation aforesaid which spacing members are located between the sides of the group, a head block on each side of said group of tubes, said head block having U- shaped conduits formed therein, the ends of which conduits are all on the same face of the head, are spaced apart the same distances as are the tubes of the group and are onlarged to form sockets of the same diameter as the external diameter of the ends of the tubes and into which sockets the ends of the tubes project, and means for clamping said heads to the sides of said group of tubes to firmly seat the respective tubes in the sockets of the U-shaped conduits.
3. A liquid cooler comprising a group of straight tubes of equal length arranged geometrically parallel with each other and with their adjacent ends in the same right line, spacing members which maintain the tubes in the relation aforesaid which spacing members are located between the sides of the group, a head block on each side of said group of tubes, said head block having U- shaped conduits formed therein, the ends of which conduits are all on the same face of the head, are spaced apart the same distances as are the tubes of the group and are enlarged to form sockets of the same diameter as the external diameter of the ends of the tubes and into which sockets the ends of the tubes project, and bolts passing centrally through the ends of the heads in the plane of the tubes for clamping the heads to the opposite sides of the group of tubes, and firmly seating the tubes in the sockets of the U-shaped conduits.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
LEWIS PURFURST. Witnesses:
SIDNEY A. FISHER, PHILIP E. MYERS.
