- ART OF MAKING GAN-SEAMS.

Specification of Letters Patent. Patented Mar. 29, 1910.

Application filed December 19, 1906. Serial No. 348,532.

To all whom it may concern:

Be it known that I, CHARLES W. GRAHAM, residing at Rome, in the county of Oneida and State of New York, have invented certain new and useful Improvements in the Art of Making Can-Seams, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the like.

One of the objects thereof is to provide a simple and practical art whereby eflicient can seams .or other joints may be formed.

Another object is to provide an art of the can seams and above general type characterized by economical use of material, high speed of working, and independence of complicated machlnery.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists-in the several steps and the order and relation of each of the same with respect to one or more of the others thereof, all as will be exemplified in the matter hereinafter set forth and indicated in the following claims. In the accompanying drawings, wherein 1s indicated one of various possible embodiments of the product of my art and a manner of carrying on the same,Figure 1 is a planview of apparatus whereby certain steps of my art may be carried on. Fig. 2 is a sectional elevation taken on the line-:z2ar; of Fig. 1. Fig. 3 is a plan of a -notched blank. Fig; 4 is a side elevation showing certain portions thereof flanged. Fig. 5 is an end view showingthe edges inassembled relation. Fig. 6 is aside elevation of the completed joint. v Similar reference characters refer to simi lar parts throughout the several views of the drawings.

Considering first the illustrative method of carrying on my art shown in the drawings and the apparatus therein set forth, there appears at 1 a driving pulley adapted to transmit power through the gears 2 and 3 to a shaft 4:, from which power is led through bevel gears 5 to the shaft 6. From the latter shaft, by means of the spiral gears 7 and inclined shafts 8, gears 9 are driven, the latter parts intermeshing with gears 10 and '11 respectively mounted upon shafts 12 and 13. Shaft 12 is provided with rotating sition, the jaws being actuated through links 23 from a spring depressed cross head 24 intermittently raised as by cam 25 uponj m shaft 6.-

Mounted adjacent abutments 19 and 20 are rotary flanging devices 26 driven from shaft 6 by the inclined shafts 27 and the spiral gearing indicated.

A sultable supporting table 28 is provided for the raw material, and if desired suitable guides may extend therefrom tothe table 15 and the clamping jaws above described.

Referring now to the manner of carrying on my art through the aid of the above described apparatus, it being assumed that suitable rectangular blanks are placed upon table 28, as indicated by the dotted lines, these blanks are transferred to the table 15 and the cutters 14 and 17 driven as above indicated, respectively form in the adjacent edges of the blank \l -shaped notches 2 9 and rectangular notches 30, as best shown in Fig. 3 of the drawings. From this point the blank is placed beneath abutments l9 and 20 and the clamping jaws 21 and 22 being thrownupwardly the sheet is securely held in position; with its outer edges projecting slightly beyond the corresponding parts of 4 of the drawings, the edges are brought.

into engagement one with another and the flanged portions hooked one within the other, or interlocked as-indicated in Fig. 5. Porby tions 33, however, rest smoothly against the inner surface of the opposite edge of the the jaws. .The-"blades-of flanging devices '13" 26 thereupon engage the projecting edge 31 blank, and form therewith a lap joint as inv dicated at 34:, this joint being of considerable in the following claims is intended to comprehend any bending of the edge whereby the same is artially or entirely folded toward the body of the blank; and it may also be noted that the expression soldering is used in a broad sense as including any method of sealing the completed joint.

Referring now to the resultant device, it may be noted that there is provided a seam possessing the high degree of strength characteristic of those of the interlockmgtype, and yet the portions over which the head is to fitare of lap joint conformation, thus presenting merely two thicknesses of material and adapting the body for eflicient connection with the edge ofthe head.

are attained and that the same possesses the favorable characteristics hereinbefore mentioned. v

As many changes could be made in the above method of c rrying on my art, and as the same could be arried on through the use of widely diflfere'n implements, it is intended that all matter contalnedin the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limitin sense. It is also to be understood that the anguage used in the following claims is intended to cover all of the generic and specific features of the invention herein described to which said claims relate and to which I am entitled over the prior art.

Having described my invention, what I claim as new and desire to secure by Letters Patent is: 4

1. The art which comprisescutting away the corner portions of a blank, flanging the edge comprehended between said portlons, flanging the opposite edge of the blank throughout a portion of its length, interlocking said flanged edges with the unflanged portion overlapping and resting upon the corresponding portion of the opposite edge, and soldering the opposite edges in assembled relation throughout saidinterlocking and overlapping portions thereof.

2. The art which comprises cutting away the corner portions of a blank, flanglng the edge comprehended between said portions,

flanging the opposite edge of the blank throughout a portion of its length, interlockmg said flanged edges with the unflanged portion overlapping and resting upon the corresponding portion of, the opposite edge,

compressing sa1d interlocked portions, and soldering the opposite edges 1n assembled relation throughout the lnterlocking and overlapping portions thereof.

3. The art which comprises cutting away the corner portions of a blank, flanging the edge comprehended between said portions, formin spaced incisions in the opposite edge 0 said blank, flanging the portions between saidincisions, interlocking said flanged edges with the unflanged portion of each of the same overlapping and resting upon the corresponding portion of the other thereof, and soldering the opposite edges in assembled relation throughout said inter locking and overlapping portions thereof.

4. The art which comprises cutting away the corner portions of a blank, flanging the edge. comprehended between said ortions, forming substantially \l-shaped incisions in the opposite edge of said blank, flanging the portions between said incisions, interlocking said flanged edges with the unflanged portion of each of the same overlapping and 1 restin upon the corresponding portion of v It will thus be seen that there is provlded an art in which the objects of my inventlon the ot er thereof, and soldering the opposite edges in assembled relation throughout said interlocking and overlapping portions thereof. I
