Abstract: 2891. Brown, T. Feb. 4. Mechanical toys. -Relates to a method of, and apparatus for, manufacturing toys, advertisement devices, &c., comprising sets of overlapping strips of sheet material, each set being mounted on a separate support, and the separate strips of one set being interleaved with the strips of the other sets, so that, by relative movements of the supports, various pictures can be successively exhibited in the same space or aperture. In one form, the machine comprises a polygonal drum 6, Fig. 2, keyed on a spindle 4 and adapted to receive a strip support 22, Fig. 4, transversely on each face, and to be rotated by a handle 5, the spindle 4 also driving through gearing 8 a leading-screw 7. A stripfeeding wheel 12 is mounted in a laterally travelling frame 11, which may be connected to the leading screw 7 by means of two half-nuts 13, 14 carried by a bracket 9 and adapted to be locked to the leading-screw by a lever 17 and latch 18. Guide-rollers 20 for the strip 28 are provided and the end of the strip is secured to the drum by a wedge 29. The positions of the strip supports on the drum are limited by stops 24, which are arranged on a helix having the same pitch as the leading-screw. In operation, the supports are covered with adhesive and the strip is wound on helically. When a predetermined number of laps have been wound on the drum, a pin 30 on the bracket 9 rings a bell 31. Owing to the overlapping, the second and succeeding laps are only secured at the edges. When the adhesive has set, the supports 22 are separated by cutting through the laps of the strip between the supports. In another form of the machine, illustrated in Fig. 7, the feed - reel is stationary and the drum moved axially on the spindle. This form of the machine also illustrates a method of interleaving the strips of a first set wound as above, with those of a second set during the winding of the latter, to form the arrangement shown in Fig. 13, wherein a second set, while being wound on a frame 65, have been interleaved with the strips of the previously-finished support 22. Referring to Fig: 7, the drum 35 slides on rods 36 carried by end plates journaled on the fixed spindle 38, part of which is formed as a leading-screw. The hub of the drum clears the leading-screw, but part of the hub is cut away to admit a half-nut, by means of which and a latch the drum may be engaged with the screw. In this form, the strip passes through a guide and tension device comprising a plate 49 and a block 50 of indurated fibre, vulcanite, &c. The interleaving-mechanism comprises an arm 54, Fig. 9, situated above each face of the drum and supported by the end plate. In a guideway in the arm slides a bar 55 normally retracted by a spring 56 and moved against the spring by a roller 70 engaging cams 71, 75, Fig. 7; adjustably secured on the bar 55 is a block 57, to which is pivoted a block having a curved finger normally pressed towards the drum by a spring 61, and moved against the spring by an arm 63, Figs. 7 and 9, adapted to engage a fixed bar or cam, such as the spindle 64, Fig. 7, of the operating-handle. In operation, a frame-shaped support 65 is placed on the drum, and a finished support 22 laid therein, the two supports being secured in position by a pin 66 and a spring clip 67. The finger is so operated by the cams as to raise a group of adjacent strips of the first set while one set of the second set is placed in position, then to release the strips, and again to raise the same group with the exception of one strip, which, due to the movement of the drum, is left covering the above - mentioned strip of the second set. A second strip of the second set is then wound over the strip thus left, and so on. When the second sets of strips have been completed, the supports are separated as before.
