Abstract: 12,008. Justice, P. M., [Plant, T. G.]. May 14. Embossing and stamping.-A machine for marking shoe soles to indicate the size or character thereof and the points at which a boot should commence or cease its operation has a movable table 18, Fig. 1, on which the sole S is placed, yieldingly connected to a plunger 23 on which is pivoted, in an eccentric mounting, a thrust arm 25. The thrust arm is moved, to be engaged by a lever 13 operated by an eccentric arm 9, by a bell-crank lever rocked by a lifter 42, which is moved to engage a shoulder on a vertical slide 45 when a sole S on the table is pressed against a back stop 51. The connexion between the back stop and the lifter is so arranged that the thrust arm is moved to engage the lever 13 only once for each movement of the stop. The table is raised by the movement of the lever 13 and lowered by springs 57. The sole is roughly positioned by fixed gauges 61, and is moved into exact position by spring- operated gauges 62, which are freed as the table rises for the marking operation. The size mark is controlled by a size-wheel 70, Fig. 11, which is connected to a gear 74 secured on a shaft 75, which carries a wheel 76 having detachably secured thereon a series of blocks 77 carrying appropriate size characters: These blocks are secured to the wheel by flanges 78 and holding- screws 79. The wheel is held in adjusted position by a spring pin 81 engaging in one of a number of shallow sockets. A second wheel 87 mounted on a sleeve 86 and provided with blocks carrying width marks is similarly controlled by a hand-operated width-wheel. Front and rear markers for indicating the points of operation of the tools are supported on the frame of the machine, as shown in Fig. 7. The markers are operated by a shaft 93 on which are splined cylinders 94, 95. The front marker 96 is carried on a slide 97, which has bosses 99, 100 adapted to carry a pin for engagement with a cam-groove 101 in the cylinder 94, the pin being fixed on the one or the other boss in accordance with the size of the shoes to be marked. The rear marker 102 has a pin 103 engaging a camgroove 104 in the cylinder 95. To allow for shoes of greatly varying size, the upper part of the rear marker is formed as a slide which can be set at varying positions on the marking-part. The shaft 93 is connected through a vertical shaft 112 to the size shaft 75, so that as the size character is altered, the front and rear markers are correspondingly adjusted. The front marker is adjusted by hand for rights and lefts, and comprises a head 116 sustained by a pivot 117 carried by supports 118 projecting from the slide 97. The upper end of the pivot is provided with a handle 119, which has a toe 120, Fig. 3, adapted to engage the one or the other side of the bevelled end portion of a holding-pawl 121. To vary the position of the front and rear markers for style, a style-shaft 125, Fig. 7, is mounted in the machine head carrying a style-cylinder 128, on which series 129, 130, 131 of style-pins are mounted; a spring-pressed pin 133 locks the cylinder in the position to which it is adjusted by a hand-wheel 126. The actuating-cylinder 94 for the front marker is provided with a collared portion 134 adapted to be engaged by the bifurcated end 135 of one arm of a bell-crank lever having an arm 137 with a bearing end portion 138 engaging the end of the style-pins 131. The cylinder 95 is similarly adjusted by the pins 129. The angular position of the front marker is also adjusted for style by pins 130 bearing against a bell-crank lever which moves a shaft 153, Fig. 3, adjusting the range of movement of handle 119. The bell-crank levers are held away from the pins 129, 130, 131 during the setting of the style cylinder by a hand-lever 164.
