This application is a division of applicants co-pending case No. 541,476, for apparatus for making'and setting one-piece can liners, filed March 6, 1922, which has matured into PatentNo. 1,436,748.

The object of the invention is to facilitate lining of metal cans to prevent discoloration and damage of the food contained.

Fig. 9 is a sectional detail view on a plane indicated by the line 99, Fig. 10; and Fig. 10 is a corresponding section indicated by the line 1010, Fig. 9. These show the third step in forming the liner.

Fig. 11 is a sectional detail View indicated by the line 11, Fig. 12 and Fig. 12 is a corresponding cross-section indicated by the line 1212, Fig. 11. These show the fourth step in forming the liner. I

Fig. 18 is a view partly in section and partly in outline on av plane indicated by the line 13-13, Fig. 14; and Fig. 14 is a corre sponding cross-section indicated by the line 1%14, Fig. 13. These show the fifth and last step in forming the liner. I

The liner 15, preferably of parchment paper, is made in one piece and should be as long as the circumference of the can plus the desired lap 17, and as wide as the inside height of the can plus allowance for folding .to cover the top and bottom as shown at 18. ,If desired, the lining may be double if the length of the liner is made twice the circumference of the can.

*quired for other shapes of cans.

for the with the bellows 23. The latter is operated means of compression s-pring24 connecting the rod 25 and foot pedal 26, which is mounted onxthepivots 27, .28 and 29.

For access to the bellows, a removable cap is provided. v A ground joint 31 may connect the bellows to the cap and the flange 32 may fasten the connecting rod to the bellows.

Pressure of the operators foot on thepedal produces an air blastthro ugh the liner form 20 and the compression spring 24 causes the bellows and pedal to return to normal position when the foot is removed.

In operation the liner. 15 is wound around the liner form 2O with the edge of the liner against the gauge 33., or contiguous to the supported end of the liner form, and with the side lap preferably on top shown in Figs. 5 and 6. v t

It will be understood that cans of diiferent sizes will require corresponding sizes of liners and liner forms. In all cases, the length of the liner should be equal tozthe inside circumference of the can plus the desired lap, and the width of the liner should be about equal to (slightly less than) the height of the can plus the length required to make the top and bottom closures.

For example, I select a standard No. 1

mainder of the liner comprises two equal divisions, the top and the bottom closures as at 18 Fig. 4:. In the case of my present example, a No. 1 standard shrimp can, divisions for the top, side and bottom closures require respectively 1%, land 1 inches width and 9 inches length.

As aforesaid the edge of the liner is placed contigously to the supported end of the liner form and wound therearound. The liner will extend 1 inches beyond the free end of the liner form, because the former is 7 inches wide and the latter is 5% inches long. The extension beyond the free end of the liner form, 1 inches of the llli.',-1'l1tll(5 or regulates the division for the bottom closure, and the extension of the liner between the free end and the supported end of the liner form, 5% inches of the liner marks or regulates the divisions for the side and top closures, 1 inches plus 4 inches, the length of the liner form.

The bottom division, or the extension of 1% inches of the liner beyond the free end of the liner form, may now be conveniently folded down to the form as illustrated in three steps, Figs. 7 and 8, Figs. 9 and 10, Figs. 11 and 12; first the part 342, next the underlip and then the flaps36 and 37.

The completed bottom folds are preferably as shown at 38, Fig. 12.

The can 89 is now impaled on the liner form over the liner and firml I held .ac'aiust the folds, Figs. 13 and 14, and the bottom closure is pressed and moulded to shape or set in the can. It is obvious that the division for the top closure will extend 1%; inches above the top of the can.

Finally, the operator presses the foot pedal 26 and the liner is first expanded from the position shown at 40, Fig. 14-, to full contact with the side of the can and then the can with the liner set is expelled from the form ready for filling with the food to be preserved.

Then the can is filled with solid food like shrimp or chipped beef or the like, the divisions for the top closure, 1% inches of the liner extending above the top of the can, may be folded down over the contents in the same way that the bottom closure was made by foldingthe bottom division, 1 inches of the liner extending beyondv the liner form, over the liner form.

The metallic cap of the can is now placed in position and the can is passed to the capping machine and hermetically sealed and afterwards processed for indefinite preservation of the food contained.

When the can is opened by cutting the side of the can just below the top scam, the contents may be emptied in a package of one-piece wrapping With uniform and symmetrical closures on the top, side and hotand setting one-piece can liners which inelude all of the elements, or th ii equivalents, set forth in'each of the following claims:

1. The method of ma king and setting onepiece liners in cans, comprising winding the liner around'a form with the liner extending from the free end of the liner form towards the supported end thereof as far as the sum of the widths of those divisions of the said liner as required to line the top and cylindrical surface, or side, of a corresponding ca" and extending from said free end therel opposite direction as far as the width of that division required to line the bottom f the i id can, turning down a plurality of folds of the said liner upon the end of the V liner form, telescoping the liner covered form with a corresponding can, jamming o crushing between the end of the liner f ."n and the bottom of the can the ears or inlary flaps resulting from the curvicar folds of the liner, thus molding the flaps and folds to the shape of the can, and then withdrawing the can with the liner set.

2. The method. of making and setting onepic e liners in cans, comprising winding the liner around a vented form with the liner extending from the free end of the liner form towards the supported end thereof as far as the sum of the widths of those divisionsvof the said'liner as required to line the top. and cylindrical surface, or side, of a corresponding can, and extending from said free end thereof in opposite direction as far as the width. of that division required to line the bottom of the said can, turning down a plurality of folds of the said liner upon the end of the liner form, tedescoping the liner covered form with a corresponding can, jamming or crushing betweenthe end ofthe liner form and the bottom of the can the ears or secondary flaps resulting from the curvilinear folds oft-he liner, thus molding the'flaps and folds to the shape of thecan, and then expanding the liner in the can, and expelling the can with the liner set by producing a blast of air through the said liner form.
