This period of submergence is one of mere Figure 1 is a broken perspective showing waiting by the operator and one of the chief my invention applied to an ice can. aims of my present invention is to utilize Figure 2 is a top plan view of a portion this period of mere waiting (now wasted) 50 of the structure shown in Figure 1. for thawing loose the drop tube and then lift- 100 ing it away with its bracket, and I provide advantageous and novel bracket structure adapted to this improvement of process. i

The former brackets for supporting the drop tube at the axis of the can have been not adapted to this advantageous change in the process, because they have been in the way of putting in a standard can dog so that the bracket and tube have had to be removed before lifting out the can and my invention broadly covers the change in system as Well as the structure that permits the change.

As illustrated in the figures, the bracket 10 hooks over the side 11 of the can 12 at some distance from the middle line 1313 of the side 11 and then extends into the can diagonally downward preferably perpendicular to the side 11 and when sufliciently far down to avoid an inserted can dog 14, 14' curves inwardly to the central axis 1515 of the can.

The drop tube 16 shown is preferably of 1 the self-centering type in order that the tube conical wall or socket '19 about a perforation 20 through the end of the bracket.

To permit a small universal lateral play of the tube the lower side of the perforation is shown downwardly flaring at 21. The hook portion 22 of the bracket is offset some distance from the middle line 1313 of the side of the can and I extend a supporting rib 23 from the oflset hook along the top of the side of the can past the middle line 1313 to prevent tilting of the bracket under the weight of the drop tube.

This supporting rib should preferably extend some distance past the middle of the side and far enough in any event to avoid any danger of the bracket tilting about the end 24 of this rib under the weight of the drop tube. The rib engages the top of the side of the can to prevent this tilting of the bracket.

In order to make it easy for an operator to properly place the bracket so 'that the drop tube will register approximately with the central axis of the can I provide a downwardly'extending dowel pin 25 located in the bracket to register with a corresponding socket 26 in the top of each can.

When putting the bracket and drop tube in place the hook is put over the side of the can and slid along until the dowel pin enters its socket and the bracket is then properly placed so that the drop tube hangs vertical in the central axis of the can.

In accord with my present invention when In Figures 5 and 6 I show two types of can dog, either of which may be used, but of which the form shown in Figure 5 is preferable in that it is readily turned to one side at the thawing tank to permit insertion of a thaw needle into the drop tube.

If the form of dog shown in Figure 6 is used it will usually be preferable to remove the dog before inserting the thawing needle as the straight portion of the dog is directly over the drop tube.

The form of dog' shown in Figure 5 has a raised cross bar 31 with downwardly directed arms 32 and 33 one of which 33 is sprung back when the dog ends are inserted in the holes I of the can.

The dogs are already well known articles of commerce and in themselves are not claimed as my invention.

In order to reduce the upsetting effect upon the bracket of roughness or foreign matter upon the edge and surface of the can and to seat the bracket firmly upon the can I cut away the middle portion of the bracket both at the top and sides as at 34, 34:.

The offset bracket support is intended to cooperate with a tube having freedom of movement with respect to the bracket but the exact nature of this movement does-not affect the broader features of my invention. I

show several different constructions. A form having a universal joint through ball and parallel with the sides of the can, lengthwise or crosswise of the can or both.

In Figures 2 11' and 12, a rectangular socket 35 is formed in the end of the bracket. The fiat bottom 36 of the socket affords a seatfor the fiat under side 37 of a rectangular flange 38 upon the fitting 39 into which the drop tube is secured. In'this form the tube does not have free sliding movement in any direction and will not swing except as it may rock either longitudinally of the can or transversely of the can. In this figure the concave guide 40 for a thawing needle is shown, as also the drainage slot 41 and the usual nozzle opening 42. The locking nut 18 has been omitted. In some cases its locking function is not needed.

In the form shown in Figure 2 13 and 14 the upper face of the bracket about the aperture forms a seat 35 rather than a socket. The seat is straight in sections across the can but is curved and is preferably concaved and circular in sections parallel to the length of the can. This is best seen in Figure 14. The fitting 39 rests upon the seat and rolls or slides upon it if its cylindrical under surface fit the seat closely or rocks upon it if the fitting be of sufficiently smaller convexity than the concavity of the seat. The movements of the tubes in planes parallel with the length of the can are thus facilitated. The nut 18 is shown here.

In the form shown in Figures 2, 10 and 15 the same construction is found as in Figures 2 13 and 14 except that the curved seat 35 and the curved under surface 37 of the fitting are here transverse to the can and the straight cross section is parallel with the length of the can, reversing conditions in Figures 2 11 and 12 and facilitating swinging movement across the can. The nut 18 is in position here.

The forms which have only partial swinging tube movement restricted in a plane or planes or which do' not move freely have an advantage with some customers in that where the can slopes the tube will assume a position intermediate between the true vertical position and the vertical axis of the can.

Some of the advantages of my invention are in the saving of time and resultant increase of plant capacity incident to thawing loose the drop tube and removing the drop tube and its bracket during a period of waiting for thawing loose the can in the thawing tank. There are further advantages in the elimination of wet and slop over the freezing floor always present if the tubes are thawed loose in place upon the freezing floor, and in the lower cost of installation from centralizing the work of thawing and removal of the drop tube and its bracket.

Instead of having to thaw the drop tubes at the cans all over the freezing floor, slopping up the floor at each can, I thaw them at one place, keeping the freezing floor dry, require much less piping for supplying the thawing water, and by the greater convenience and saving of time increase the output of the floor.

In view of my invention and disclosure variations and modifications to meet individual 'whim or particular need and to obtain part or all of the benefit of my invention without copying the structure of the drawing will the art and I therefore claim all such in so far as they fall within the reasonable spirit and scope of my invention.
