To all @vltontitfmay concern? Be It known-that 1, ROB RT P.-CAR R, a. citizen of the United States, and'resident of Buffalo,.in.the county of Erie, inthe State ofiNe'w York,l'1aye inventednew and useful 1 Improvements. in Methods I -Hames,.of1which the following, taken in connection with the. accompanying ldrawof Making ings', is a full, clear, and exact description.

.Thls invention has referencemo reparticularly to, the method: of. manufacturing sheet'metal hames of'the' type in which the hameis formed from a single piece or blank of sheet metal, and thelobjectlof'this inven.-,

tion' is to improve; simplify and; cheapen theproc'ess -of manufacture and construction of hamesof this type, and'produ'ce a neat .appearing,'-- strongand durable hame: which I willresemb'le a wooden hame in size, weightand general appearance, .butwill be much stronger and more durable.

Other ob' t's and advantages willi appe'ar from the following description taken in conthe accompanying drawings, in

offset from the remainder of the blank by A longi i tudinal section of the blank is then" suitable. pressure, or otherwise, to form a step-portion +6 longitudinan of." the.

blank, as shownin Figs. 4 and 6. The blank is then bent into trough ofU-shape, of the form illustrated in Figs. 5 and 7. This 7 U-shaped? blank isthen' adapted to'receive a permanent core, 7 of wood or other suitable material, such core being illustrated in Fig. 8, and having a series of slots or kerfs .-8- formed therein, so that the core may be bent with the sheet metal shellto the desired form in the finished hame. The

blank and the opposite edges of the ends of the blank are bent, as by suitable dies, around the core, the'lateral edge extension -3 overlapping the opposite edge of the blankto reinforce the same for a purpose :pleted hame, but is substantially straight throughout its length. The next step in the process consists in bending the blank and its core longitudinally to the shape of a com pleted hame, theopposite ends of the hame being bent or deflected in opposite directions, as shown in Fig. 13. A suitable conduit or opening 9 is then drilled through the end of the hame at which the lateral edge extension 3 is positioned for the reception of a bolt or other suitable device 9 for securing a hame strap attaching member 10- to thehame and this opening extends through the sheet metal shell, the permanent core and the lateral edge extension -3, the extension 3 forming an additional thickness of metal for supporting such attaching means, as shown in Fig. 14:. The next step in the process consists in punching a suitable series of openings -11 through the sheet metal along one side of the hame,-as.shown in Fig. 16. A suitable series of openings -12- are next punched in the opposite side of the hame, said openings registering with openings -11 punched in the opposite side of the hame for the passage of staples, bolts or other suitable means for attaching the trimmings and draft devices of the hame. These staples, when passed through these openings in one side of the sheet metal hame and driven or otherwise forced through the wooden core, preferably are of suflicient length to extend a short distance from the opposite side of the hame in such manner as to be offset or clenched against the sheet metal wall.

The trimmings and draft devices, as shown in Fig. 19, comprise the ball cap 13- as shown formed with a flange 14- extending longitudinally of and attached to the hame, the top loop staple 15 with its loop ring -16, the line ring 17, the backstrap ring -18, and the hame strap attaching member -10. The back-strap ring 18 and the line ring 17 are preferably attached to the hame by members extending through the sheet metal shell at opposite sides of the longitudinal joint, and offset or clenched against the face thereof to not only firmly support the said rings, but

to strengthen the shell and prevent any tendency to spread at the joint. A. supple mentary ring 19 may likewise be at tached to the hame in a similar manner.

The overlapping edge extension -3- not only serves to reinforce this end of the hame, but the bolt 9 passing therethrough and through the metal shell also tends to prevent any movement of the opposite edges of the blank from their abutting position.

The completed hame is similar in many respects to that shown in Letters Patent No. 1,091,87 and No. 1,098,928, granted to C. L. Wiedrich, March 31, 1914 and June 2, 1914, respectively, and although I have shown and described this particular form of-hame as constructed in accordance with the method herein, yet it is readily apparent that this series and sequence of steps and operations may be applied to the manufacture of sheet metalhames of various forms, shapes and constructions, without departing from the spirit of the invention as set forth in the appended claims.

What I claim is 1. The method of making hames, consisting in forming a sheet metal blank of desired shape, punching a series of openings in opposite edges thereof, offsetting a portion of said blank, bending the blank into trough shaped'form, inserting in the trough shaped blank a permanent core suitably kerfed,

bending the opposite edges of the ends only of theblank around the core, then bending the intermediate portion of the blank around the core so that the edges abut in a joint extending longitudinally of the hame, then bending the blank and its core longitudinally, perforating the blank to receive attaching means for draft devices and trimmings, and securing the draft devices and trimmings in place.

2. The method of making hames, consisting in forming a suitable sheet metal blank, bending the blank into trough shaped form, inserting into the trough shaped blank a permanent core, bending the opposite edges of the ends only of the blank around the core, then bending the intermediate portion of the blank around the core so that the edges abut in a joint, then bending the blank and its core longitudinally, perforating the blank to receive attaching means for draft devices and trimmings, and securing the draft devices and trimmings in place.

3. The method of making hames consisting in forming a sheet metal blank of desired shape and having a lateral edge extension, punching a series of openings in the intermediate portion of the opposite edges of the blank, bending the blank into trough shaped form, inserting in thetrough shaped blank a permanent core, bending the opposite edges of the ends only of the blank around the core so that the lateral edge extension overlaps the opposite edge of the lank, then bending the intermediate portion f the blank around the core so that the edges abut in a joint extending longitudi- I nally of the hame,;formingan opening extrimmings, and securing the draft devices- I tending through the shell at opposite sides and trimmings in place. 10 of the joint and through the lateral edge In Witness whereof I have hereunto set extension for the reception of attaching my hand this ninth day of October, 1914. means for a hamestrap, then bending the Y ROBERT P.
