Abstract: 19,279. Winter, C. Sept. 2. Parcelling.-The boxes or other articles to be wrapped are fed in any suitable manner from a table 34 to a table 5 placed at a lower level, the foremost box being pressed down on to the table 5 by an arm 35. A pusher 36 then moves the box along the table 5 against a wrapper, which is held in a hooked or trough-shaped support, the wrapper and box being ultimately pushed into one of a series of recesses or receptacles 1 x in the periphery of an intermittently-rotated drum 1, wbich is narrower in width than the article to be wrapped so that the article projects on each side of the drum. The box is thus wrapped on the rear, top, and bottom sides, the wrapper projecting at the ends and at the front. The lower projecting-edge at the front, which is shorter than that projecting at the top, is folded up against the front of the box by a metal blade 41 carried on a bell crank. The drum is then rotated a step by pawl-and-ratchet gearing, and a rounded end 53 of a cover 52, enclosing the drum, comes against the top projecting edge of the wrapper, which is thus folded on the front of the box over the lower edge of the wrapper. When, by the rotation of the drum, the box is carried to a position diametrically-opposite its first position, it is pushed out of the drum by pushers 54, which engage with the projecting portions of the box at each side of the drum. The pushers 54 carry spring-actuated wings, which, by means of guides or inclines, are caused to fold the rear projecting edges of the wrapper against the ends of the box. As the box advances, the front projecting edges come against fixed horns 62, by which they are folded against the ends over the rear flaps. The further advance of the box caused by the succeeding boxes, folds the lower edges of the wrapper against the ends by means of fixed curved projections 63. The box ultimately arrives over a platform or elevator 64, which lifts the box within vertical side pieces 65, by which the top end flaps are folded, thus completing the wrapping of the box. The flaps may be cemented by coming into contact with cementing-devices on each side. When the elevator is again depressed, the box is held by spring latches 70, which prevent it from descending. The platform or elevator may be replaced by an endless chain of lifts, in which case the spring latches may be dispensed with. When the box is ultimately pushed, by the succeeding boxes, above a table or horizontal exit channel 71, it is pushed by a pusher 72 into a box placed in position to receive it ; or the boxes may be removed by hand or by a travelling band. The paper from which the wrappers are formed is fed from a roll 13 over a guide-roller provided with pins 15, which enter perforations near the edge of the paper, the paper being pressed against the roller by rollers 16. The paper thence passes between rollers 17, one of which is provided with blades 18, which are adapted to operate against blocks of rubber or equivalent yielding-material 19 carried by the other roller to indent or cut partly through the paper on the line of severance of the wrapper. The paper next passes between two sets of rapidly-moving endless tapes 20, guided over rollers, as shown, which sever the wrapper and feed it into position on the trough. The rollers &c. by which the paper is fed are actuated from the main shaft 11 by toothed gearing, and the various pushers &c., by which the wrapping is effected, are actuated from the main shaft by crank &c. mechanism.
