LASTING-MACHINE.

Specification of Letters Patent. Patented June 27, 1916.

Application filed November 6, 1912, Serial No. 729,831. Renewed October 30, 1915. Serial No. 58,938.

To all whom it may concern Be it known that I, Gnonon N. GonnoN, a citizen of the United States, residing at Brockton, in the county of Plymouth 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 machines for use in shaping end portions of shoe uppers and is herein shown as embodied in end lasting mechanism of the type used in bed lasting machines for working an upper into lasted position and about the toe portion of a last.

In lasting the toes of shoes the upper has a tendency to slip back from under the wipers after they have tensioned the upper about the toe and while they are being operated to wipe the upper inwardly over the edge of the last thus producing a shoe the edge of which is shaped with insufficient accuracy at the toe. It also happens, particularly with unsymmetrically shaped lasts, that a greater resistance is encountered on one side of the last than on the other'in closing the wipers over the toe of a shoe and this causes the toe of the last to be shifted out of symmetrical relation to the wipers so that the upper is not laid against the shoulder of a welt innersole equally on both sides of the toe.

A feature of the present invention consists in the provision of novel means adapted to hold the toe of the last securely in symmetrical relation to the wipers while they are being closed and another feature consists in novel means to cooperate with end embracing wipers for greater eliiciency in shaping the upper at the edge of the shoe. The means herein shown comprises a set of toe holding plates, or auxiliary wipers as they may be termed for convenience, having an inflexible edge contour corresponding to the contour of the edge of the last as distinguished from the contour of the channel lip or shoulder lines to which the overlaying wipers are shaped for lasting welt shoes. The auxiliary wipers are mounted directly below the overlaying wipers where they are adapted to embrace and center the toe portion ofa last through out the toe lasting operation. These hold-V ing plates are illustrated as arranged for vertical movement with them'ain wipers to wipe upwardly along the side faces of the last toward the last edge to tension the upper about the toe of the shoe and then to cooperate with the main wipers by clamping the upper under tension against the outer sides of the last while the main wipers wipe the upper inwardly over the last edge and against the lip or shoulder of a welt innersole, thus avoiding the liability of the upper slipping back. jIt is also to be noted that a well defined angular edge is thus formed on the shoe between these outer and top metallic forming plates instead of the rounded edge which is liable to result from the usual rubbing action of a single set of wipers upwardly and then inwardly over the last A further feature of the invention comprises means for operating the holding plates independently of the main wipers to advance them into operative position on the shoe, though the said means will preferably be located adjacent to the means for operating the main wipers, so that an operator can actuate both sets of plates by one hand. Means is illustrated to lock the holding plates in position to hold the work infiexibly while the upper is being wiped inwardly by the main wipers.

The several features of the invention will appear mo-re'fully from the following de scription ofthe mechanismin which the invention is shown as embodied and will then be particularly pointed out in the claims.

Figure l is a perspective View of a toe lasting mechanism equipped with a pre-- ferred embodiment of this invention; Fig. 2 is a vlongitudinal sectional view of the toe lasting mechanism shown in Fig. 1; Fig. 3 is a perspective detail.

The toe lasting head is substantially like that shown and described in United States Letters Patent N 0. 552,834, granted January 7, 1896 on application of Edward 'F. Grrandy and comprises the tilting support 2 presenting a bearing 4 for a sleeve 5 which is adjustable in said bearing by a crank 6 at i about an axis extending lengthwise of the machine. I

The front end of the sleeve 5 is broadened and flattened to present a supporting table 8, which is provided with a cover plate 9, and interposed between the table 8 and plate 9 are the carriers 10 which have a sliding movement to actuate the wipers 12 attached thereto by the clamps 11. Roller studs 14 which rise from the tableS hold the cover plate 9 in place and stand in cam slots in the carriers 10 which are connected by links .15 and a cross head 16 with a plunger 17 extending axially through the sleeve 5 and operated by the hand lever 18 which for this purpose is fulcrumed upon a bearing bracket 20, and has pivoted thereon a recessed block 21 in which is received a segmental block 22 fast on the end of the plunger 17. Through these connections the wipers receive from the lever 18 and plunger 17 a combined advancing and closing movement to lay the upper over the feather 23 and against the shoulder of the welt innersole shown in Figs. 1 and 2. As explained in the above mentioned patent the toe lasting head has also, by means of a treadle, an upward movement to cause the wipers of that patent, after having embraced the toe below the innersole, to wipe the upper upwardly along the side faces of the last to the edge of the shoe bottom.

In addition to the wiper plates 12 above described there are provided in accordance with this invention, auxiliary toe holding plates 2% located between the wipers 12 and the table 8 as shown in Figs. 1 and 3. The auxiliary plates are actuated by a duplicate set of carriers 26 which are arranged to have a sliding movement similar to the carriers actuating the main wipers, they being conveniently mounted in the same manner. These carriers are connected by links 28 and a cross head 30 with a plunger 32 extending axially through the sleeve 5 and are operated by a new lever 34 fulcrumed to the bracket 20 and connected to theplunger 32 by a loose connection in the same manner as the above described connection between the lever 18 and plunger 17 which allows for the transverse tilting of the toe lasting head. The levers 18 and 3% are provided with pawls 40 and 41 on their inner faces to engage ratchet faces formed on the upper and lower faces of a stationary bracket arm 43 on themachine frame, whereby said levers can be locked in position.

The holding plates 241, the body portions of which are advantageously about as thick as the wipers 12, have acting edges which may be widened vertically by depending lips as shown to provide acting faces that will extend from the lower face of the wiper 12 down across the edge of the innersole and have a secure but narrow bearing against the side of the last near its edge. It is regarded as important that these acting faces be only wide enough to insure the above mentioned results because it is very desirable to concentrate their action upon the stock which is at and immediately adjacent to the shoe edge in order to obtain the most effective upper shaping action. The plates 24 are preferably advanced into position to embrace the toe of the last with the main wipers and, being of suitable edge contour relatively to the edge contour of the wipers 12, are enabled to position the toe centrally with the line of action of the wipers. Being each inflexible and unyieldingly connected to their operating lever 341 those holding plates clamp the toe rigidly in central position throughout the operation of the wipers 12 in overlaying the upper against the lip of the innersole. As the toe lasting head is raised by the treadle the holding plates may assist the wipers in rubbing the upper upwardly along the side faces of the last to stretch and conform it to the shape of the last or the holding plates alone may perform this function, while the wipers 12 are advanced and closed insuificient to contact with the work, until raised to a position substantially fluslrwith the last bottom. When the plates 2 1 and 12 reach this vertical position, shown in the drawings, the holding plates'2d cooperate with the wipers 12 by clamping the stretched upper against the sides of the last and preventing it from slipping back while the wipers are actuated to wipe the upper inwardly over the last edge and against the shoulder of the innersole. The holding plates also cooperate with the wipers to form an angular edge in the angle between them as shown in Fig. 2; the wipers pressing downwardly by a treadle, not shown, on the feather and the holding plates concentrating lateral pressure by the lever 34: on a narrow area around the toe at and adjacent to the shoe edge.

Having explained the nature of the invention and described a preferred embodiment thereof, 1 claim as new and desire to secure by Letters Patent of the United States:
