Abstract: 13,395. Plant, T. G. Oct. 19, 1909, [Convention date]. Treeing and ironing. -In an ironing and dressing jack, Fig. 1, front and back leg plates 10, 9 are pivoted together at 11, and are detachably secured by bayonet-joints to a projection 8 of a barrel 3, which is rotatable by means of a hand-wheel 4 in the upper part of a column 1. The rear plate 9 is slotted to accommodate an expanding member 23, which is normally held within the plate 9 by a spring 25, but is adapted to be moved outwards to adjust the jack to the size of upper under treatment; the member 23 is locked in its adjusted position by a spring pawl 29 and ratchetteeth 27. Extending through the barrel 3 is a spindle 34 formed with a groove to receive an expander 35, Fig. 4. The right-hand ends of the spindle and expander are adapted to enter the last pin socket, and are shaped as shown in Fig. 4, so that relative movement between them will lock or release the last. The spindle and expander are normally and yieldingly held projecting to the right, Fig. 1, with the end portion of the spindle expanded. The contraction of the spindle to receive a last is effected by treadle mechanism acting through levers 55, 57, 59 on a cap-piece 41. The last is placed on the end of the spindle, and the shoe, last, and spindle are then forced to the left, Fig. 1, causing the ends 12, 13 of the leg plates 10, 9 to pass over the crown or cone of the last and between it and the upper or lining. A spring- pressed locking-arm automatically engages teeth 65 on the spindle to lock the spindle in the position into which it is moved; the arm is released by the depression of a second treadle, which acts through the levers 77, 75, 73 on a toe 72 carried by the locking-arm. To give the shoe a movement transversely with respect to the leg plates 9, 10, in addition to the longitudinal movement just described, the spindle 34 and the expander 35 extend through a slotted portion 82, Fig. 5, of a lifter 81 passing through one end of the barrel 3. The lifter is raised on the depression of a third treadle, by levers 94, 92, Fig. 1, the end 98 of which is adapted to engage the bottom of the lifter; a spring- pressed pawl 87, Fig. 5, locks the lifter in its adjusted position. The spindle 34 and expander 35 rest upon a spring-pressed plunger 84, Fig. 5, so that when the lifter is raised, the last and shoe are given a similar movement, which is of a yielding nature. A stretcher to stretch the upper in a diagonal direction may be provided. This consists of two fingers 104 adapted to engage the eyelets of the upper; they are connected to a head 103 of a spring-pressed piston 101 mounted in a cylinder 100, which is adjustably carried by a bracket 99. The machine is in duplicate, so that the operator may be ironing and dressing a shoe on one jack while a shoe on the other jack is drying. The columns of the two machines are geared together so that the jacks move in unison; locking-means are provided to hold the columns in their forward positions.
