Specification of Letters Patent.

Patented J nne 25, 1912.

Application filed January 2, 1912. Serial No. 669,016.

To all whom it may concern:

Be it known that I, MAURICE V. BRESNA- HAN, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines of the bed type and more particularly to features of heel lasting and shoe supporting mechanisms adapted for use with toe lasting mechanism which may be of the type shown in reissued Letters Patent of the United States No. 13,1d7 of August 23, 1910. The heel lasting mechanism of this type of machine comprises a heel embracing band which extends about a shoe below the plane of the last bottom and clamps the materials of the rear part of the upper to the last, and heel lasting plates or wipers which have a sliding movement inwardly over the edge and bottom of the shoe and lay the marginal portion of the upper down in position to be tacked to the heel seat portion of the innersole. The band is closed first in order that it may hold the upper materials against springing away from the side faces of the last at and adjacent to the last edge when the wipers bend said materials over the last edge. The closing of the band establishes a definite relation between the last and the heel lasting mechanism determined by the contour of the portion of the last embraced by the band and which is locatedsome distance below its sole'face. In many modern lasts the contour of this portion of the last, as represented for example by a section parallel with the last bottom and taken a half inch or more from the bottom, differs in important respects from the contour of the last bottom with which the wipers have to deal. For example, the inner side of the front part of the heel and of the rear part of the shank slope inwardly in many lasts to a much greater extent than does the corresponding portion of the outer side of the last. Such lasts are not therefore properly positioned by the heel band for the action thereon of the inner side of the last bottom far enough unless they are advanced too far over the outer side. To meet this condition I have, for the first time so far as I know, provided an end lasting machine in which an end embracing band on the one hand and the end wipers on the other hand can be relatively adjusted angularly. By this adjustment, which I make of the wipers, I position the heel wipers so that the lasting plate that operates at the inner side of the shoe can close adequately over the last bottom without closing the other one too far. This is herein done by mounting the wipers for angular movement laterally together as a unit and relatively to the heel band about a center which may conveniently be at the rear end of the heel. As shown, the sup porting head and a wiper carrier have cooperating curved guide slots and guide pins which permit the wipers to be adjusted, after closure of the band, into symmetrical relation to the contour of the heel portion of the last bottom. The said guide pins may have winged clamping nuts by which to secure the parts in adjusted position and when loosened permit quick readjustment from a right to a left shoe or vice versa. A flexibie connection is provided between the wipers and their operating mechanism by which they can be actuated equally well in any ad justed position of the wipers. Machines of this type are commonly arranged for the heel lasting mechanism as a whole to slide away from a lasted shoe to permit the removal of that shoe and the presentation of another one to the machine, said mechanism being spring actuated for this purpose. The shoe is supported by a heel pin which partakes of this backward movement and by a toe rest which is associated with the normally stationary toe lasting mechanism. The heel pin also has a movement relatively to the heel band for freeing the lasted shoe from the band. After a shoe to be lasted has been applied-to the heel pin the heel lasting mechanism is drawn forwardly with the shoe against the resistance of its return spring, the operator guiding the shoe into A carriage.

proper relation to the toe rest with his left hand and using his right hand to produce the movement. In accordance with a further feature of this invention I have provided a treadle and a toggle to be straightened thereby for producing this movement into position where a lock secures the lasting mechanism automatically. A special arrangement of the toggle is preferably provided by which it responds immediately to the action of the return spring when permitted to do so.

The heel pin has heretofore been actuated to draw the last backward firmly into the heel band by a hand wheel acting through a pin journaled in the heel lasting mechanism carriage and a rack slide in which the heel pin is located. A ratchet" face was formed on the hand wheel and a pawl was carried on a lever which was normally pressed toward the hand wheel by a spring and was reversely pressed by a knee lever pad on the lever to disengage the pawl. For this hand wheel and its locking and unlocking means I have substituted a hand lever connected with the pinion and arranged to be engaged by the free right hand of the operator while he advances the heel carriage by the new treadle and toggle instead of by hand power as heretofore. A locking pawl is carried by the hand lever and operated by a pinch lever which can lift it from a ratchet face on a drum. Novel means is provided for releasing this pawl automatically when the return spring for the heel lasting mechanism carriage is retracting the For this purpose a release dog is pivoted on the hand lever and pinion shaft and has a heel that stands in contactwith. or closely adjacent to an abutment on the support over which the carriage travels and which turns the dog into position to lift the pawl immediately after the return spring begins to act and the carriage starts back. By releasing the heel pin at this time the toe of the shoe is pulled more gradually or from the toe rests and liability of injury to the shoeis avoided.

These and other features of the invent-ion, including certain details of construction and more important combinations of parts will now be described in connection with the drawings and then pointed out in the claims. Figure 1 is a side view of a machine equipped with this invention; Fig. 2 is a plan view of the heel lasting mechanism, the usual cover plate for the wipers being omitted; Fig. 3 is a perspective view of the heel pin retracting and unlocking devices; Fig. 1 is an end view, and Fig. 5 is a section through the hand lever and pinion shaft.

The frame 2 of the lasting machine may be of conventional form with a head or openwork table 4 upon and within which the front and rear carriages for the toe and heel lasting mechanisms slide from and toward each other. The frame supports a power shaft 5 connected at 6 with a cam shaft 8 bearing cams and connections similar to those shown in United States Letters Patent No. 521,954 and forming no part of this invention. The toe lasting mechanism of this machine may be in essential respects like that shown in reissued Letters Patent No. 13,147 granted to me August 23, 1910 as assignee of Frank Holbrook, and need not be herein described.

The heel lasting mechanism carriage is supported on rollers or wheels 10 that run on a track within the frame table as inclicated in Fig. 1 where the frame is broken away to show this. A toggle has one member 12 connected at its rear end to the frame and the other member 14; connected to the heel lasting carriage while near the knuckle of the toggle the member 141 is connected to a treadle rod 15 the lower end of which is attached to a lifting treadle 16. A locking pawl 18 having a handle 20 is pivoted in the carriage and a spring 22 holds the pawl in position to engage over the front end of a rail 24 on the frame as soon as the treadle and toggle have forced the carriage forward to its working position. The pressure on the treadle is then discontinued and the treadle rod drops as far as the partially straightened toggle permits, see Fig. 1. A return spring 25 connects the front end of toggle member 14: with the frame in position to draw the carriage to the right when permitted to act. The connection of the treadle rod to toggle member 1 1 is by a link 26 that has a lug 28 located to engage the knuckle of the toggle and a spring 30 connects the. knuckle pin with the rod and link pin. When the treadle rod drops, after pawl 18 has locked the carriage, the spring 30 is put under tension and immediately after the pawl 18 is lifted at the end of the lasting operation said spring 30 starts the toggle to flexing. This spring serves as a separate return actuator for the toggle and prevents the toggle from acting as a resistance to the pull of the return spring.

Within a guideway in the carriage slides a rack slide the front end of which has a bearing for the upright heel post 36 that supports the last and carries it firmly back into the heel band. For this latter purpose the rack slide 35 is engaged by a pinion 38 on a shaft 40 the hub 42 of which has an operating hand lever 15. This lever is arranged in such convenient angular position that the operator may grasp it with his right hand and apply power advantageously to draw the last back into the band while with his foot he operates the treadle 16 to advance the entire heel carriage and with the left hand he guides the shoe upon the toe rest 44. By this arrangement the manual work of the so-called jacking operation is performed with a minimum of effort. A segment ratchet 46 is carried by the carriage, in which the shaft 40 is journaled, and 011 the hand lever is pivoted a pawl 48 for engagement with the ratchet to lock the last under backward pressure in the heel band. A handleor pinch lever 50 rises from the pawl and extends along the lever 45 to be grasped by the same hand as that lever for releasing the pawl. On the inner side of the pawl is a roller 52 and loose on the shaft 40 is a cam 54 that has a heel 55 which stands, while the heel carriage is advanced, in a recess in the rail 24, see Fig. 4. The cam has also a projecting eccentric face which, when the heel comes in contact with a shoulder on the rail, is thrown up against the roller 52 to lift the pawl from the ratchet and free the heel post automatically in time relation with the retraction of the heel carriage and hold the pawl off the ratchet until the heel carriage has been again advanced nearlyto latching position. It will be noted that the heel post is released by its pawl as soon as the carriage has traveled back far enough for the heel 55 to strike its abutment which may be only a short distance so that the shoe is dragged only very slightly back over the toe rest and the toe rest may be mounted to have a limited backward sliding movement which will minimize chance of injury to the shoe by it.

Upon the heel carriage there is mounted by the transverse pivot and adjusting screw 62 the usual tilting head 63 for the heel lasting devices, including the heel embracing band 64 and the wipers or lasting plates 65. The band is attached at its middle to the head and its ends are connected by levers 66 to slide bars 67, the rear ends of-which have connection through an equaliZer bar 68 with a plunger 69 the rear end of which is pressed upon by a lever 70 actuated through a spring 71 and rock shaft arm 72 from the cam shaft 8, all as well understood by those familiar with this type of lasting machines and substantially as shown in Patent No. 552,834 and no novelty is claimed for this heel band mechanism.

In a plane immediately above the top edge of the heel band the wiper carriers 75 rest upon a plate 76, see Fig. 2 which lies upon the top face of the tilting head 63. Gibs 78 confine the wiper carriers laterally and the adjacent edges of the wiper carriers, the gibs, and the plate 76, are all curved about a center located adjacent to the rear end of the heel and near the center of closing movement of the wipers. These parts and the cover plate 80 are adjustable toget-her about this center and relatively to the heel band, being guided in such adjustment by curved slots 82 in the gibs and threaded studs 84 which rise from the head 64 through the slots and receive binding nuts 85, Fig. 1, to clamp the wiper mechanism in angularly adjusted relation to the heel band. The wipers are operated by a hand lever 90 and plunger 92 which is connected to the usual crossbar 94 by a link 93 to permit the adjustment of the wiper mechanism with relation to its operating plunger. The crossbar 94 is connected by links 95 with the wiper carriers 75 which have cam slots 96 in which stand roller studs 97 rising from the plate 76 which, as above explained, accompanies the wipers in their adjustments relatively to the heel band so that the same operating movements are given to the wipers in all adjusted positions. In order to direct and guide the movement of the crossbar 94 said bar has a rectangular boss guided in a similarly shaped way in the plate 76. By loosening the binding nuts 85 the operator is enabled to shift the wiper mechanism angularly toward the right or the left according to whether the shoes to be operated upon next are lefts or rights and then to secure said mechanism in adjusted position by tightening the binding nuts again.
