SYRUP-COOLING DEVICE.

Specification of Letters Patent.

Patented July 17, lacs.

Application filed April 10, 1905. Renewed June 13, 1906. Serial No. 321.504.

To all whom it may concern:

Be it known that I, GABRIEL OARLsoN, a citizen of the United States of America, residing at Springfield, in the county of Hampden and State of Massachusetts, have in vented new and useful Improvements in Syrup-Cooling Devices, of which the following is a specification.

This invention relates to cooling devices, and has special reference to a device of this character for cooling syrups, the object of the invention being to provide a construction in which the parts are so disposed as to subject the syrup to as extended an area of cooling-surface as practicable and in which the circulation of the water or like cooling agent may be effectively applied to the surface of the parts with which the syrup is in contact.

The invention will be fully described in the following specification and is clearly. illustrated in the accompanying drawings, in which Figure 1 is a top plan view of a cooling de vice in which the invention is embodied. Fig. 2 is a sectional elevation in the plane of line 2 2, Fig. 1, with the exception of the inlet-pipes, which are in full lines.

Referring to the drawings, the shell of the cooler is indicated by a and is cylindrical in form, the upper end being open, the lower end being provided with a downwardly-tapering bottom I), at the apex of which is a valve 0. The form of thisvalve is immaterial, but preferably is of the sliding cut-off type shown herein, as this is the most eflicient for use where viscous substances are to be handled.

The bottom I) of the cooler is made with a double wall, as shown, to provide the space d, which constitutes a water-chamber into which water is admitted through the inletpipe f, preferably located near the apex of the bottom. At some point on the bottom, preferably opposite the inlet-pipef, the pipe g enters, through which Water may be conveyed from the double bottom to the top of the cooler, the pipe 9 extending to a point somewhat above the upper end of the shell a, as shown, and screwed onto a header h, from which the pipes j depend and enter annular chambers 7r, concentrically disposed about the axis of the shell. These chambers k are the water-chambers and have closed bottom ends and preferably open upper ends, and they are supported on the upturned edges of a plurality of angle-irons m or simi lar suitable supports, which may be bolted to the bottom of the cooler, whereby the lower ends of the chambers may be held out of contact with the bottom, the angle-irons being notched, as at 0, to prevent the charm bers Zc from sliding. By means of this construction the syrup may circulate freely, passing around between the chambers 7c, the spaces 1) between which are all in communication at the bottom of the cooler because of the raised position of these chambers above the bottom.

The number of the water-chambers is reduced in the drawings, and they may be more orless numerous, according to area of coolingsurface required relative to the mass of the syrup to be cooled. The smaller central chamber constitutes practically a conduit, whereby the syrup may be introduced into the cooler by means of a funnel, as shown in dotted lines, or otherwise.

To regulate the height of water to be maintained in the cooler, through which a constant stream is passing when the device is in operation, an overflow-pipe g is passed through the wall of the shell (1 at the proper height therein and extends through the walls of all the water-chambers to and through the outer wall of the innermost chamber, to which it is secured, collars ,1" being fitted over the pipe g between andin these chambers and against the shell (1, and on the outer end of the pipe a nut r is screwed up against the outer collar, and thus binds all the others together and locks the water-chambers together and maintains the proper spaces between them, there being holes 8 bored through the collars and through the pipe g in each water-chamber. Thus when the water reaches the height of these holes it will pass therethrough and flow out through the pipe g.

By means of the herein-described construction the syrup may be effectually cooled and all of the parts removed easily from the shell for purposes of cleaning the same, this being a very desirable feature. Separate supply-pipes leading into each water-chamber aid in maintaining an even temperature therein.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. A cooling device comprising a shell having a cone-shaped double bottom constituting a chamber for the cooling liquid; a. plu- I trically disposed within the shell, means of rality of annular circulating-chambers arranged concentrically in said shell and extending from one end nearly to the other, the inner ends of said chambers being closed, and there being a passage for the contents of the shell between the bottom of the latter and said inner ends of the chambers; a conduit communicating with said double bottom and extendingupwardly and over the top of the shell, pipes depending from said conduit into the annular circulating-chambers, and an overflow-pipe extending transversely through the wall of the shell and the walls of the circulating-chambers, there being perforations in that part of said pipe located in the latter, and a suitable valve for the lower end of said double bottom.

2. A syrup-cooling apparatus comprising a cylindrical shell having a cone-shaped bottom, a series of annular chambers concensupport for said chambers on said coneshaped bottom, said support comprising angle-ir0ns located in said cone-shaped bottom, there being open spaces between the charm bers and between the lower ends thereof and said cone-shaped bottom; a valve located at described.
