To allwhom z't may concern: A A Be it. known that I, CALVIN C. FoU'rs, a citizen vof the United States, residing at Middletown,` inthecounty of Butler and State of Ohio, havev invented certain new yand useful Improvements in IceCans, of which'the followingis aspeccation, reference-being had therein'to the accompanying drawing.

This invention relates to ice cans, such as are used in the manufacture of ice, and similar structures. l

` The object ofthe invention is to produce a can of this character which will bej strong,

rigid and durable; and which will have 'no parts exposed and subject to corrosion. To

this end it is a vfurther object of the invention to produce a can of this kind which may be galvanized after its construction has been completed, without distortion. It is also an object of the invention to provide such a can in which no rivets or' similar fastening devices will be used. p

In the accompanying drawing, Figure 1 is a sectional view taken vertically of a can embodying my invention; Fig. 2 is a t-ransverse sectlon taken on the line 2 2 of Fig. 1; and Fig. 3 is a sectional detail view of one of Athe lower corners of the can.

` In these drawings I have illustrated one embodiment of my invention` and have shown the same as applied to Ian ice can, which in its general shape and dimensions conforms to the standard construction. It will be understood, however, that while the invention is particularly adapted to ice cans, for reasons which will hereafter appear, .it may be embodied, either as a whole or 1n part, in cansor metal receptacles of various kinds and for various purposes. The standard ice can is about inches in height, consequently the drawin s are on a greatlyreduced scale. There ore, forthe sake' of clearness, Ihave showncertaln features of the invention in :1n-exaggerated form and somewhat out of proportion to the structure as a whole. J Y

Ice cans of the type here illustrated are tall, rectangular cans'` which must be of great strength and rigidityn In forming the can, a sheet of metal of a width corre-` sponding. approximately to the height of the can is bent to a rectangular shape, to provide the can' with side walls 1 and end walls 2, and the adjacent edges of the sheet Specification of Letters Patent.

are united one to the other by gas or electrical welding, as shown at 3, so as to form a practically integral construction without joints. Preferably the end and side walls of the can are formed from a single sheet of metal, but this is not essential as the adjacent edges are all welded and a jointless can is produced regardless of the number of pieces employed in its production. The can is provided with'a bottom wall 4, which `1n the present. construction consists of a plate of metal having its edges bent downwardly to form flanges 5 which, when the bottom pla'te is inserted in the lower part of the body portion of the can, as shown in Figs.- 1 and 3, will extend substantially parallel with and will be arranged in close relation to the lower portions of the respective side and end walls. The flanges and the lower portions of the side and eed walls form the supporting structure for the can and are preferably welded one to the other, as shown at 6, so as to produce a very strong and rigid support. The lower portions of the side and end Walls are preferably offset, as shown at 7, to receive the bottom structure, andthis oii'set provides shoulders which eX- tend inwardly about the adjacent edges of the bottom wall and bring the respective side and end walls into substantial alinement with the respective flanges of the bottom structure. The shoulders of the side and end walls t snugly about the adjacent corners of the flanged bottom wall so as to leave a verv small space between said Walls and the ybottom structure and to provide a very strong, rigid construction. The side and end walls may be welded to the bottom structure along theshoulders, or offset portions 7 if desiredbut this is not necessary as the Structure shown here yhas ample strength and the spaces along` the edges of the bottom wall areso small that they will be completely filled during the galvanizing process. The upper end of the can is preferably stiffened by a reinforcing bar or strip 8, which may be secured thereto in any suit-` character, and particularly an ice can,

should be galvanized after its construction has been completed, thus causing all parts .thereof to be protected and avoiding any raw edges or exposed parts which would be subject to corrosion. lIt has been found'very difficult, if not impossible, to galvanize a can of this character after it has been conipleted, due to the tendency of the walls to buckle, or be distorted, during the galvanizing process. This buckling or distorting is objectionable in any type of can or receptacle, but it renders an ice can worthless because the ice formed therein conforms to the irregularities in the walls thereof and either cannot be removed at all or is very difficult to remove from the can. To enable the completed can to be galvanized, as a whole, I have so constructed the same as to prevent the side and end walls from being distorted or buckling durin the galvanizing process. This I accomp ish by providing the walls of the can with ribs, or grooves, which permit, and compensate for, the expansion of the metal when it is subjected to the heat of the galvanizing bath. The ribs may project either inwardly or outwardly and may be of any suitable number. For the purpose of illustration, I have here shown the walls as provided with inwardly projecting vertical ribs 10 which extend for the greater part of the length of the walls, there being two ribs in each side wallsl and one rib in each end wall. The ribs may be of any suitable character, but I prefer that they should be V-shaped in cross section, as I find that they accomplish their function very eectually when produced in that form and give greater strength and rigidity to the walls than would ribs of other shapes. In the construction here shown, the ribs have their lower ends arranged close to and preferably resting u on tit lill

the bottom plate or wallA 4, and have t eir upper ends tapered toward the top of the can. Where the top of the can is reinforced, as shown in the present instance, it is not necessary that the ribs should extend to the top thereof and I have here shown them as terminating short distances from the upper edges of the respective walls. rI` he lower ends of the ribs resting upon the bottom wall serve to greatly strengthen and stiffen the structure as a whole, and this function maybe further increased by welding the ribs to the bottom plate 4, as shown at 11 Iin the can illustrated. While the `'ribs may be formed in any suitable manner, I have in the present instance formed them by a combined bending and drawing operation.` The lower portions of the ribs are formed almost wholly by bending, while the upper portions of the ribs are formed very largely by drawing the metal from the' walls. This construction results in a contraction of the lower portion of the walls which gives the can its tapered shape and enables the tapered can to be formed from a rectangular sheet of metal. Of course the surplus metal below the ribs `is removed and the adjacent edges of the walls united by welding. If desired, the bottom wall 4 may also be provided with a rib 12, which will strengthen it and prevent it from buckling. rIhe ribs in the side and end walls are preferably spaced apart substantially equal distances with the result thatthe block of ice formed in the can ismarked for division into equal parts, thus facilitating the cutting up and distribution of the cake.

It will be apparent from the foregoing description that I have provided a `can which is very strong and rigid in its construction and which is very durable. connections having been made by welding, the can is to all intents and purposes jointless and has no rivets or other fastening devices. The construction being such as to permit the can to be galvanized after it is completed, all seams and edges are coated and thus protected against corrosion. Further it willl be apparent that I have accomplished these results in a can which can be very easily manufactured and which can be produced at a cost but little in excess of the cost of the ordinary can, which does not have the advantages set forth.
