NESTING- ICE-CAN.

Specification of Letters Patent.

Patented Nov. 24, 1914.

Application filed February 16, 1914. Serial No. 819,042.

To all whom it may concern:

Be it known that I, FRANK F. BENTLEY, a

citizen of the United States of America, re-

to nest one within the other, and having stout bottom rims consisting of three thicknesses of metal, and has for its object to improve this type of can by rendering the same capable of being easily nested, and at the same time without losing any of the advanta es of a non-nesting construction.

Vith these and other objects in view my invention consists in the novel details of construction and combinations of parts, more fully hereinafter disclosed and particularly pointed out in the claims.

This invention is an improvement upon that disclosed and claimed in my prior Patent No. 1,027,802, dated May 29, 1912, and entitled Ice cans.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the I views-- ed up into the position shown in Figs. 1, 2'

and 3; and Fig. 5 is a plan view of a portion of a blank from which the bottom of my can is made.

As is well known to those skilled in the art of making ice cans, they are subjected to exceedingly hard usage, so that unless the bottoms are especially reinforced and made exceedingly strong, leaks are sure to develop sooner or later and to cause a great deal of annoyance inthe manufacture of ice. It is further well known that a bottom the floor or support on which it rests, and it was to overcome these various objections that I provided the ice can disclosed in my patent above. However, it was found later that the shipping of these cans is unduly expensive, on account of the fact that they do not nest, and further it is not possible to make them nest, because the folded flanges of the bottom ofnecessity must entend in prolongation of the straight side Walls of the can. Should the walls of the can be made tapered as has been heretofore proposed, the bottom shown in the patent above could not be employed because the meeting edges of the members 8 in said patent would overlap and other objections would be-encountered which would render the blank out of which said bottom is made useless for the purpose of a nesting can. In other words, referring to Fig. 5 of the drawings if the dotted line 1 represents the line of fold of the flange where it joins the bottom 2, and if the dotted line 3 represents a similar line of fold at right angles to the line 1,- then, the prolongation of the line 1 to the point 4 on the flange 5 and the prolongation of the line 3 to the point 6 on the flange 7 will represent the shape of the blank employed in a non-nesting can such as that disclosed in my patent above. On the other hand, in order to form a can capable of nesting it is necessary to incline the bottom flanges of the finished can to the bottom thereof as best illustrated in Fig. 2, and therefore the blank illustrated in Fig. 5 must be designed to accommodate this inclination. 1

Accordingly, in forming my blank I cut the metal along the line 8, causing the said line to make an angle with the line 1 proportional to the amount of inclination desired in the completed bottom flange or foot, and I draw the line 10 at a distance from the line 1 equal to the depth it is desired to give to the bottom flange or foot which depth of courw is a measure of the distance the bottom 2 will rest above the floor or support. In this way the flange 19 is formed. I next cut the metal, along the line 11', measuring oil a distance substantially equal to thus forming the reversed flange 7 as will be clear from Fig. 5. I next draw the dotted line 12 inclined to the line 10 at an angle equal to the obtuse angle between the line 8 and the prolongation of the line 1. Next I provide an extension 13 to the reverse flange 7 which is preferably narrower at what will be its bottom end 14 than at its upper end 15,-a-s shown. The width of this extension will depend upon the thickness of the walls 14 of the can, as will presently appear, and it is made wider at its end 15 than at its end 14 for a purpose that will also presently appear. The metal is out along the line 16 making an angle to the line 3 the same as the angle the line 8 makes with the line 1 and the dotted line 17 is drawn at the same angle to the line of told 18 that the line 12 makes with the line 10.

The reverse flange 5 has a depth the same as the reverse flange 7, and the flange 20 has a depth the same as flange 19 above disclosed. The reverse flange 5 is provided with an extension 21 which when folded at its lower end 22, is narrower than its upper end 23, and in all respects the same as 'the extension 1f;- just described.

The blank being formed in the manner above, the metal is next bent inwardly to the plane of the bottom 2 along the lines 1 and 3, until the edges 8 and 16 meet, whereupon it may be bent upward and inclined outward along the lines 10 and 18 until the edges 25 end 26 of the extensions 13 and 21 respectively also meet, thus leaving a groove-like space between the flanges l9 and 7 and theflanges 20 and 5, for the accommodation of the walls 14 of the tapered can, as will be clear from an inspection of Figs. 2 and 3.

It is evident that if the angle 27 made by the walls 141 of the can is perfect, so that there is no unevenness in the metal and that if the bend 28 of the walls 14 of the can, as best illustrated in Fig. 2, presents no unevenness, but is perfect, then the extensions13 and 21 could be the same width at the ends 14' and 22 that they are at their ends 15 and 23 respectively. But in practice there is always more or less lost space in fitting these cans, and unless there is a perfect joint between the parts the deficiency must be made up by solder. The. filling up of bad joints by solder of course prevents leaks, but-at the same time, it is not so desirable, worman'lilre or eficient as the careful. fitting of the metal in the first place. Accordingly in order to get a perfect fit, notwithstanding the fact that more or less space is lost in the fitting of the walls 14 to the space between the flange;

' 19 and 7 and between the flanges 20 an respectively, 1 1 refer toinake the extensions 13 and 21 wi or at their claim 15 "and 2h nriaoaa than they are at their ends 1 1' and 22, which enables the metal to come together nicely along the. lines 25 and 26 as shown in Fig. 3, notwithstanding the above defects in the joint. Further, by thus providing plenty of metal to meet along the lines and 26 the joint is better bracedand enabled to produce a nesting can which is just as efiicient as the can 011. my said patent and which is much more valuable, in that the cost of shipping is greatly reduced.

What ll claim is:
