SPECIFICATION forming part of Letters Patent No. 735,783, dated August 11, 1903.
Application ledMaroh 21, 1903 To LZZ whom, t may concern:
Be it known that I, BERNARD H. LARKIN, a citizen of the United States, residing in May wood, in the county' of Cook and State of Illi-` nois,have invented a new and useful Improvement in the Manufacture of Key-Opening 'longued-learing-Strip Can-Bodies, of which the following is a specification.
My invention relates to improvements in the method or process of manufacturing.key-- opening tongued-tearing-strip can-bodies.
Heretofore in the manufacture of key-opening tOngued-tearing-strip can-bodies it' has been customary to first cut the tin-plate into can-body blanks long enough to form the canbody and the projecting tongue of the tearing-strip and then cut away from the end of the blank the surplus stock at each side of the tongue, so as to leave the tongue projecting, as required; and then make the scores or weakened lines at the sides of the tearingstrip to form the blank into a can-body and solder the side seam thereof.
The object of my invention is to provide a method or process by meansl of which the amount of scrap or Waste produced in the man-V ufacture of tOngued-tearing-strip can-bodies may be greatly reduced.
My invention consists in the means I employ to practically accomplish this Object or result-that is to say, it consists in first cutting from a sheet of tin-plate a'double can-body blank, a blank equaling in length two 'canbodies and one tongue, and, second, in dividing this double-length blank into two canbody blanks and simultaneously forming two projecting tongues by cutting out from the middle portion of the double blank an intervening piece of scrap out of which both of the two tongues are formed, the tongues being staggered in respect to each other, thus producing two blanks, each having a projecting tongue.v The two tongued can-body blanks are thenscored and formed into can-bodies in the usual manner. By this means one-half of the scrap or waste heretofore ordinarily produced is saved, and the labor and expense are also reduced, as the tongues are formed on both blanks by one and the same operation.
To enable my invention to be more clearly .j SerialNo-148,987. (No model.)
and readily understood by those skilled in the art, I have in the accompanying drawings, which form a part of this specification, illustrated the successive steps or stages of the manufacture of can-bodies by my invention.
In said drawings, Figure l represents the double can-body blank inlo which the sheet of tin-plate is out as the first step of my method or process. Fig. 2 illustrates the second step by which the double can-body blank is divided into two single can-body blanks each provided with a projecting tongue by cutting out from the middle portion of the double blank a single piece of scrap out of which both tongues are formed, one staggered in respect to the other, the top edge of the double blank in part forming the top edge of one of the single can-body blanks and the bottom edge of theother. Figa?) shows one of the can-body blanks after it has been scored or provided with weakened lines to mark off the tearing-strip, and Fig. 4 the same formed into `a can-body.
In the drawings, A represents a double canbody blank into which the sheet of tin-plate is out as the first step, this blank equaling in length two can-bodies and one-tongue. are the two single can-bodies formed from this double blank A by cutting out of its middle portion the single piece of scrap C and simultaneously forming a tongue d on each of the can-body blanks B. The dies which cut out the piece of scrap C also at the same time form the notches d' at each side of each tongue cl. The separat-e can-body blanks B, each having a projecting tongue d, are next scored or provided with weakened lines d2, which mark olf the tearing-strip d3, and then the same are formed into can-bodies D and the side seams` d thereof soldered in the usual manner.
I claiml l. The improved method Or process of manufacturin g key-opening tongued-tearingstrip can-bodies,consisting in first making a double can-body blank, and then dividing the same into two single can-bodies each having a projecting tongue by cutting out from the middle portion of the blank a single piece of scrap from which both tongues of the two can-body blanks are formed, one tongue being left intelOO gral with eaeh @an -body blank and both tongues being out out of the waste middle scrap piece at the saine time said waste iniddle scrap piece is out from between thetwo eaubody blanks and finally scoring the can-body blanks thus produced and forming them into can-bodies, substantially as specified.
