a heel seat lasting machine of the bed or wiper type. j v

An object of this invention is to produce a machine by which end lasting can be performed more expeditiously and with less labor than heretofore.

An important feature of this invention consists in the combination with means for holding a shoe, of end embracing wipers and automatic power driven operating mechanism connected with the wipers for causing them to work the upper material into lasted position. The automatic operating mechanism may be arranged to cause the wipers to advance repeatedly over the shoe bottom. Preferably, in connection with the automatically operated wipers, means is provided for moving the shoe relatively to the wipers. The shoe moving means may be arranged to lift the shoe into a higher plane with relation to the wipers after they have initially broken down the upper materials. This enables the power driven wipers to iron down or compress the overwiped portion of the upper materials firmly upon the insole and give to the lasted portion of the shoe the detail of form or contour and the permanency of shape which is desired in a well lasted shoe.

Tn accordance with a further feature of this invention, novel means is provided for clamping and maintaining the upper materials firmly againstthe side faces of the shoe end while they are being lasted down upon the'insole by the power driven wipers. This feature of the invention .is embodied in improved mechanism for closing and holding the heel embracing band whereby very secure clamping of the upper isobtained with automatic adjustment of the band end closing pressure for right and left lasts that have very difierent shapes, Prat! erably the band closing mechanism is operated by a treadle and advantageously this treadle and the one by which the shoe is uplifted are located adjacent to one another in position to be engaged by different portions of the same foot of the operator whereby he can with ease variably control the band closing and the shoe uplifting pressure.

The several features of the invention, including certain details of construction and combinations of parts, will appear from the following description of the illustrated embodiment of the invention and will then be pointed out in the claims.

Figure 1 is a perspective view of themachine; Fig. 2 is a-plan View; Figs. 3 and d are sectional views illustrating the operation'of the lasting plates upon the stock.

The machine comprises a base 2 which may be fastened to a bench or table or may have a pedestal supporting it from the floor. This base hasat its front end upstanding ears 3 between which there is pivcted at 4 the machine head 5 which carries the lasting devices; This head is adju'stably supported in the rear of the pivot l by the screw rod 6. This mounting permits the longitudinal inclination of the lasting plates to be varied by adjustment above the pivot rod l. The head is formed with a longitudinal bearing at 8 for the rearwardly extending cylindrical stem portion 10 of a plate 12 upon which the heel lasting devices are carried. The bearing 8 is. formed to expose a worm toothed portion of the stem with which'the screw rod 15 engages to effect transverse adjustment of the lasting devices about the aXis of the stem 10. The

crank 16 provides convenient means for turning theL sc-reyv rod.

The stem 10 has a sliding bearing for a rod 20 having a cross-bar 22 which is connected by the links 24 with the wiper carriers 25 to which the wipers or lasting plates 26 having formed edges extending toward the shank of the shoe are removably at: tached. The wiper carriers have cam slots 28 in which stand rollers on the fixed studs 30 that connect the plate 12 with a cover plate 32. The outer edges of the wiper carriers are curved to engage walls of the recess in the plate 12 in which the wiper carriers are inclosed by the cover plate. These walls and the cam sl ts2 sh t a tilt direct inward closing movement of the wipers as they are advanced by their link" wipers; At its other end the driving shaft has a loose pulley 44 and a clutch 45 is adapted to be moved into driving enga ement with the pulley by a wedge 46. iis clutch is operated by' a hand lever 48 to start and sto the machine.

A heel em racing band 52 is fastened to a chain which, at the rear, see Fig. 2, has a stud projecting into a recess in the head 5 where it is secured by a binding screw 54. At its front ends the band is supported by chain arms 55 having forwardly directed inner ends and which are fulcrumed on slide bars 56. The chain arms or levers are connected at their outer ends by links 58 with a pivoted cross-bar 60 on the end of the band closing rod 62. This rod is fastened at its rear end to a lever 64, see Fig. l, fulcrumed at its right hand end and connected at its left hand end by a spring with the stationary stand in which the driving shaft has its bearing. This spring pulls the operating rod 62 backwardly to open the band. Movement in the reverse direction for closing the band is efi'ected by a slide rod 66, Fig. 1, which extends from the left hand end of the lever 64 to a chain 68 that runs over an idler to a treadle 70. The slide bars 56, upon which the chain arms 55 are fulcrumed, are guided for endwise movement in the head 5 and each slide bar has on its outer edge, see Fig. 2, a wedge face or incline 7 5 which is held yieldingly by a spring plunger 76 against a stationary bearing face '78. This eonstructionand arrangement provides that as forwardmovement of the links 58 is effected to close the band the slide bars will be forced forwardly and as theyadvance they will be, wedged inwardlyto shut the end portions of the band firmly against the sides of the last. The band is thus caused to clamp the upper materials, including the usual heel stiffener, firmly about the heel portion of the last and the band is so formed, as appears in Figs. 8 and 4, that hard pressure of the upper materials against the last is secured at the upper edge of the last over which they are to be bent by the wipers or lasting plates. A final hard band closlng pres sure mav be ebtained by adjustably limlting the forward movementof the slide bars, as by stop pins 7 9, and causing the last portion of the movement of the links 58 to be 86 toward and from which the toe rest can be adjusted for different lengths of shoes. The heel rest carries a last pin 90 and has movementabout a pivot 88 by means of a spring pressed plunger 89 to tip thetoe end of the shoe firmly down upon the toe rest for holding the shoe in place on the support. A guide bracket 95 embraces the bar 82 and confines the shoe support against lateral movement and limits forward movement of the support relatively to the lasting devices from which it is moved to apply and to re-,

move a shoe as will be readily understood. it sprmg 96 draws down the shoe support when the treadle is released. The illustrated arrangement provides that the shoe support will stand normally depressed and tipped away from the machine as far as the bracket permits.

In the use of the machine a shoe will be applied to the support and then the support pushed back into the heel band and raised but in practice I contemplate that the oper- .3

ator will depress the treadle 80 with the heel portion of his foot and then force down the treadle 70 with the toe portion of the same foot and will maintain his foot upon the treadles during the brief period which is required for the heel seat lasting operation by this machine. The shoe having been jacked and clamped as described, the operator will engage the clutch controlling lever 48 and start the machine, causing the wipers to advance and close over the heel from their normal open position, Fig. 3, to the position shown in Figs. 1 and 4. The driving mechanisms will rapidly reciprocate the wipers repeatedly over the heel seat and back again while the u ward pressure of the shoe against the wipers is controlled by the operator through the treadle 80 and the band closing pressure is controlled by the treadle 70. The first advance of the wipers may take place with the plane of the shoe bottom slightly below the lower face of the wipers,

as'shown in Fig. 3, to break down the heel stiffener and other upper materials and then the :shoe be raised, as indicated in Fig. 4, to J to uncover the tacking line and the upper may be tacked around the heel seat as usual by a hand tacker While the shoe remains in the machine. Alternatively the machine may be stopped with the wipers entirely backed off and the shoe, with the heel portion shaped to the sides and to the bottom face of the last, may be removed. from the lasting machine and presented to a tacking machine for fastening the upper materials in lasted position.
