Abstract: 19,931. Nyberg, C. S. Sept. 16. Match boxes.-In machines for making the shells or outer cases of match boxes for safety matches from wood or like shavings held together by papers pasted around them, the shaving is folded down on the bar 1 by the apparatus shown in Figs. 1 and 2, paste is applied to the paper on the table 17 of the mechanism shown in Figs. 3 and 4, the pasted paper is drawn by the carrying device shown in Fig. 5 from the table 17 over the shaving folded around the bar or pattern block 1, and the paper is pressed or smoothed on the shaving by the apparatus shown in Fig. 8. The shavings after being scored are fed out one at a time and conveyed to the stationary bar or pattern block 1, on which each shaving is intermittently pushed and successively placed in the vicinity of the devices arranged along the bar for completing the shell. The two double-armed levers 3, 4 on the shaft 5 are so formed and situated that the lower ends on their descent come each on its own side of the bar 1, while the upper ends are situated one on each side of the stationary pin or rod 10, so that a shaving is first met by the levers at a short distance away from the bar and then brought against the aides of the bar. The paste magazine for the paste table 17 is fitted with an up-and-down adjustable shutter, the edge of which has teeth to lay out the paste in furrows and allow air under the paper placed on the paste to escape. In front of the paste magazine is the paper magazine 22, which can be raised and lowered, and is so placed that the ends of the papers extend beyond the free edge of the table 17. The paste table 17 is mounted on the rotatable hollow shaft 18, in which the sliding shaft 24 carrying the paper magazine 22 is mounted. The shaft 24 is actuated by the lever 27. To raise and lower the presser-plate 33 mounted as usual above the paper in the magazine, the plate is connected with the rod 34 which is clasped by the gripper 37 at one end of the lever 38. The gripper lifts the rod and presser-plate when the lever is raised, but when the lever descends the rod is released. The tongs, Fig. 5, with the jaws 45, 46, seize the end of a paper and draw it out over the bar on to an outer case on the bar, and the presser-foot 12 mounted above the bar descends and presses the pasted paper on the outer case. One jaw 46 is pivotally fitted in the arm 47 so that the paper may be held fast along the entire breadth of the jaws. The ring rotatably mounted around the bar 1 as usual, for pressing the paper fastened to the outer case, has the arm 60 pivoted to it, which arm supports at one end the presser roller 58 having longitudinal grooves on its surface, and at the other end is provided with the lever, 64 acted upon by a spring. In the path of this lever, there is a cam arranged so that the presser roller may travel round the outer case during the rotation of the ring and be kept at a distance from the outer case by the cam when no roller action is required. The roller 58 is supported by the fork 59, which is pivotally connected with the arm 60 in order that the roller may be able to set itself in a position to constantly press with its entire length against the paper. The two levers 68, 69, acted on by the cams 70, 71 and the springs 72, press the ends of the shaving lying on each other, as well as the side of the outer case adjacent to the ends, against the bar, but upon the arrival of the roller at these sides, the levers are withdrawn from the outer case by the cams.
