Abstract: 16,403. Cutlan, F. Sept. 14. Uppers.-Relates to pulling-over machines for adjusting uppers on their lasts, previous to lasting. The last is supported so that the operator can see the upper during the pulling - over operation, while it can be turned upside down to enable the tacking to be easily performed. As shown in Fig. 1, the last-supports are carried by a spindle C<1>, which can be rotated to reverse the last and is held in the desired position by a spring-lock C<8> engaging notches in the bearing. The sole of the last rests on pins, one of which is adjustable by means of a nut C<9>. A hinged horn C', pressed forward by a screw, clamps the last in position. A pivoted packing-piece E<4>, on which the screw bears, can be turned aside to facilitate the adjustment of the horn. The pulling-over pincers G and G<1> are carried by a spindle F, adjustable lengthwise to suit different - sized lasts. The toe - pincers G are pressed together to grip the upper by a spring, and the outer leg has a handle G<3> by which they can be manipulated. To the outer leg is pivoted a lever G<4> coupled to a rack gearing with a pinion H<1>. The lever bears on a roller on the inner leg of the pincers, so that, when the rack is pulled down, the upper is firmly gripped and pulled over the last. The pinion is rotated by a lever which is locked by a pawl engaging a stationary ratchet-wheel H<4>. The two pairs of side pincers G' are similarly operated by a rack K. In a modification described in the Provisional Specification, cords are used to operate the pincers, the said cords being pulled taut by wheels or segments. After the upper has been pulled over by the means described, it is wiped over at the heel and toe by the apparatus described below. In a recess in the head C is a sliding plate L, operated by a lever L<12>. On the upper side of this plate is a rod L<2> moving in bearings L<1> and pressing with its rear end on a spring L<3>. This rod has at one end a crosshead, to which are hinged a pair of jaws L<5>. A recess in the underside of the plate L contains a block L<7> slotted to receive pins on the undersides of wiper-plates L<9>. These pins are pulled towards one another by a light spring. While the last is in the position shown in Fig 1, the lever is operated to move the plate L towards it. During this movement the jaws L<5> swing round and press the upper firmly round the heel of the last. Further movement of the plate brings the inner parts of the wiper-plates against the upper, and they consequently swing inwards about their pivots and wipe the upper over the insole. After the last has been inverted, the upper is wiped over at the toe by the means shown in Figs. 1 and 5. This wiping-apparatus is carried by, and is movable on, a counterweighted arm M which is swung up when required. To a saddle-piece, movable on the arm, is pivoted a plate N<5>, adjustable as to inclination by a screw N<22>. In a recess in the plate is a block N', slotted to receive pins depending from the wiper-plates N<10>, which are pivoted at N<12>. When the plate is moved inwards, by the rack-and-pinion gear shown, the wiper-plates swing inwards and wipe over the toe as described above with regard to the heel. A pad N<13> in front of the wipers is movable inwards against a spring.
