MANUFACTURE OF CUTLERYa SPECIFICATION forming part of Letters Patent No. 274,318, dated March 20, 1883.

' Application filed July lS, 1882. (No model.)

To all whom it may concern Be it known that I, HAD R HALLsTRoM, of Eskilstuna, Sweden, have invented a certain new and useful Improvement in the Manufaca welding them together and to the knife or arof the same between the dies.

ticleitself, whereby a strong, durable, and light handle is formed, which cannot become detached from the knife or other article.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the handle-blank. Fig. 2 is a longitudinal sectional elevation of the same, showing it pressed between the dies. Fig. 3 is a cross-sectional. elevation of the pressed blank and the dies. Fig. 4 is a plan tndinal elevation of the blank for the knife or other article of cutlery. Fig. 6 is a longitudinal'sectional elevation of the same between the dies. Fig.7 is a cross-sectional elevation Fig. 8 is a longitudinal elevation of the pressed blank. Fig. 9 is a longitudinal elevation of the completed knife or fork between the dies. Fig. 10 is a cross-sectional elevation of the same.

r A blank, to, of sheet-iron or steel, is placed between two dies,A and B, and hollowed out or concaved, and the concaved part is then punched out of the blank. In the same manner one end of a long blank, b, which has the length of the knife or fork, &c., is placed between the dies 0 D, is hollowed or concaved by the dies, and is then punched out on the dotted line. The pressed handle blank a, or

the handle-blank I), must be a right-hand 5 blank and the other aleft-hand blank, so that when the open sides of the blanks are placed together a hollow handle will be formed, onehalf of which is made integral with the knife or fork itself. The two handle-blanks, having been placed against each other in the manner described, are then heated to the welding-heat. and are placed between two dies, E and F, and are subjected toblows or to pressure between the dies, whereby the two handle-blanks will be welded together, and will form a hollow handle integral with the knife, fork, or other article. It is evident that both handle blanks can be made out of short strips of metal, and the two can both be Welded to the blade. After having been welded, the knives,forks, &c., and their handles, are finished, ground, and polished. Light, strong, and durable handles can thus be made very easily and rapidly, and they cannot become separated from the knife or fork. I Handles for screw-drivers, chisels, gimlets, draw-knives, 860., can also be formed in the manner described above. view of thepressed blank. Fig. 5 is a longi- I am aware that it is not new to out out the blanks from sheet metal,or cast them into the desired form and then braze or solder them together ;but

What I claim is- The method of forming hollow metallichandles on knives or forks which consists in first HADAR HALLSTRUM.
