Specification of Letters Patent.

Patented July 1, 1913.

Application filed March 19, 1912.. Serial No. 684,712.

-Massachusctts, have invented certain Improvements in Toe-Lasting Mechanisms, of wlnch the following descriptlon, 1n 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 has for its object to improve the toe lasting mechanism andas sociated parts of the machine.

Experience has demonstrated that many shapes of shoes can be lasted satisfactorily with toe wipers whichare positioned with one side uppermost for the right shoe and are inverted to present the other side uppermostfor the left shoe. It has been proposed in prior Patent No. 1,028,990, issued June 11, 1912, on an application filed June 6, 1910 in the name of Louis M. Brown to remove wipers from their carriers and transpose and invert them for the purpose of using them on right and left shoes. This procedure involves some delay in the use of themachine, frequently requires the employment of tools to loosen and again tighten the wipers and demands a special construction of the wiper carrier and of the attaching portion of the wiper. In my prior application Ser. No. 597,055, filed Dec. 10, 1910, I have shown toe embracing and shaping plates in the nature of lasting plates or wipers which are mounted in an invertible head or holder for use with right and left shoes and have therein claimed that invention broadly;

The object of this present invention, which is shown as embodied in a toe lasting mechanism like that shown in my prior United States Patent No. 1,018,477, dated Feb. 27, 1912, is to provide an improved invertible mounting for the toe wipers, putting the inventive ideas .of said prior cases into the best practical form.

The invention further comprises novel means for locking the Wiper holder which permits the usual adjustments of the wipers found desirable in a toe vlasting mechanism; means for moving the toe rest out of the path followed by the wiper holder while the holder isbeing. inverted, said means preferably operating automatically and servlng also to return the toe rest to and maintain it in its operative position; means for adjusting the toe rest automatically for sizes of the same style of lasts, and improved means for adjusting the toe rest with relation'to its usual operating mechanism for variations m'the thickness of the. toes of different styles of lasts.

Another feature of the invention is found in a novel construction of toe wipers whereby they are adapted more effectively to work the upper up the sides of the last and to lay it over the last edge free fro-m wrinkles. Thls wiper has a very thin acting edge above and back of whichis a wall against which the upper may bepressed and frictionally' held by a toe spreader. The thin edge eliminates opportunity for the formation of wrinkles between the lower and the upper faces of the wiper; The wiper, because it is-intended to be invertible, is made with in connection with the accompanying drawings and will then be pointed out in the claims.

Figure 1 is a side view of a lasting machine embodying this invention. Fig. 2 is a plan view. of the toe head. Fig. 4 is a similar view with parts removed and broken away to show the toe rest swinging mechanism. Fi 5 is a similar perspective showing the toe rest adjusting means and illustrating the use of the new toewipers. Fig. 6 is a sectional view illustrating the use of the toe wipers. Fig. 7 is a detail to be referred to.

The portions of the machine intended for operating at theheel end of the shoe will preferably be like the disclosure in my prior Patent No. 1,018,47 7

The frame 1 supports the toe lasting head for movement vertically by the treadle 2 and excess pressure lever 3 having the pawl and'ratchet, as shown, by which to lock the wipers'nnder pressure in toe ironing down Fig. 3 is a perspective view combinations of parts will now'be described position'over the shoe bottom. A slide 4 is adjustable lengthwise by the usual screw and hand wheel 6 on the table that constiadjustment positions the toe lasting mechanism for long and short shoes relatively to the heel lasting mechanism which occupies a constant operative position for all sizes of shoes. The slide 4 bears a segmental guiding rib 8 which is T shaped in cross section and is curved about a center in a pivot pin 10. Upon this pivot pin is mounted a block 12 which has a guideway for the rib 8 by which it is held rigidly down and pre vented from canting. An adjusting screw with a hand wheel 14 is used to position the block 12 and the toe lasting devices and their operating mechanism carried by it in desired angular relation horizontally about the axis of pin 10 for the crookedness of the right or left last that may be in the machine. From the block 12 rise arms between which, see Figs. 1 and 3, is pivoted at 15 on a transverse axis the carriage 16 that supports the toe lasting devices. An upright screw rod i 18 with a crank handle connects the rear-end of the carriage with a rigid arm that extends backwardly from the block 12 and the screw rod is used to adjust the carriage and lasting devices vertically about the transverse axis formed in the pivot 15.

The carriage 16 has a long cylindrical bearing in which can turn the stem of an invertible wiper holder 20, see Fig. 4. The front portion of this holder is a rectangular box-like structure within which are supported and guided the wipers 22 and their operating mechanism which is shown best in Fig. 2. This operating mechanism comprises wiper carriers 24 in which the wipers are removably held by clamps such as 23 in Fig. 3, said carriers having cam slot-s 25 into which project studs fixed to the underlying plate of the holder. The carriers 24 are connected by links to the cross-head of an operating rod as usual, the rear end of which rod is suitably connected to a handled lever 29 of the second class whereby lever movement will advance and retract the wipers in paths determined by the cam slots 25. The carriage 16 has a lateral arm 17 in which is threaded a handled rod 30 carrying a barrel shaped block 32 having a circumferential groove and the end portions of which are tapered outwardly from the groove toward the rod. The wiper holder has at either side a rearwardly projecting spring bolt 34 and that one of the bolts on the side adjacent to the block enters the groove in the block and thereby locks the invertible wiper holder from turning on the axis of its stem except as it is adjusted by rotation of the threaded rod 30 which can be turned to effect adjustment of the wipers about the longitudinal axis of the head for transverse inclinations of difierent shoe bottoms. This adjustment, like that about the transverse axis 15 and about the upright axis 10, can be made with the invertible wiper holder 20 and its wipers either side up and without disturbing the locking means 34 for said holder.

The toe is sustained for lasting upon a rest which for the best results is located under a portion of the shoe acted upon by the wipers 22. There is not clearance for the wiper holder and wipers to turn over for inverting the wipers without interference with the toe rest while the latter occupies its operative position. The holder '42 for the rest is therefore pivoted at 43 to the slide 4 so that the head of the rest can tip toward the heel when it will be out of the way of the wipers when the wiper holder is turned over. Another advantage in so .mounting the toe rest that it can tip is that the rest may follow with the shoe and, by swinging downward, relieve its contact with the shoe in the usual unj acking operation in- .stead of compelling the shoe to drag over it. I The above described novel arrangement permits tipping of the toe rest but prefer- Eably means is employed to effect this turning and .a restoration of the toe rest automatically with the inversion of the wiper holder. Therefore the rest holder 42 has a lateral stud 44 engaged by a sliding latch 45 {yieldingly held by a spring 46 in a block 48 that projects laterally from a slide bar 50. This slide bar has pin and slot connections at 52, 53 with the toe head block 12 and the plate 4. On the rear end of the bar is a post 55 operatively connected with a cylinzdrical cam 56 that is on a short shaft which has bearing in the block 12 and carries a pinion 58. This meshes with a pinion 60 that is carried on a shaft 62 geared at its left hand end to the stem 20 of the wiper holder. Through this connection the cam pushes the toe rest forwardly for the wipers to pass it and then draws it back again to operative position. To permit the lateral adjustment of block 12 and the parts carried by it, including the cam 56, about pivot 10 by the hand wheel 14 without disturbing the latch 45 and block 48, the connection from the slide bar 50 to the cam is made through a head block 63 that slides freely forwardly and backwardly by its stem and has a slot to receive the post 55 and a stud which stands in the cam groove.

The foot 65 of the toe rest stem is curved on its lower side to facilitate the tipping of the rest. This foot is connected, as usual, to the stem by screw threads permitting adjustment to the right height to support the particular thickness of last under the wipers. It is inconvenient to reach this foot to make the adjustments and therefore a properly inclined support 70, Fig. 5, for the toe rest foot is herein provided for making the adjustment of the toe rest automatically as the toe head is adjusted forwardly and backwardly relatively thereto by the hand wheel 6. It is important to prevent the foot 65 from turning and getting off its S11} port and the support is therefore provide with a guiding groove 72 for the foot. Furthering elevations required for diiferent thick' nesses of different styles of lasts. This adjustment is provided by furnishing the support with a stem threaded in a beveled gear wheel 78that is confined in the block 7 The block also has bearing for a hand wheel shaft 80 that carries a beveled gear meshing with the one marked 7 8 and through which shaft the lasting machine operator can easily, and without soiling his hands with machine grease that would disfigure light colored shoes, make the required adjustment of the toe rest for the style of last to be operated with.

The wipers 22 prefer-ably are formed with a thin operating edge from whichthe surface slopes back for a short distance to a wall 86 against which the upper materials can be gripped by a spreader 9(). The invertible wiper shown in Figs. 5 and 6 is made with upper and lower operating edges 85 separated by a V or U shaped recess into which the spreader crowds the upper. This construction of wiper permits the spreader to hold the upper free from wrinkles more close to the acting edge than does any other wiper of which I am aware whereby greater certainty is obtained that the toe of the shoe will be smoothly lasted. Also the recess adjacent the gripping wall 86 permits a folding in of the stock by the spreader which is very eflective in securing a tightly lasted toe. If the wiper is not to be inverted the upper edge or lip 85, Fig. 6, is simply omitted, leaving the wall 86 higher. 1
