Patented Oct. 4, 1932 UNITED STATES rarer Fries FRED KICKS, F LEICESTER, ENGLAND, ASSIGNOR TO UNITED SHOE MACHINERY COR- IPDRATION, OF PATERSON, NEW JERSEY, A CORPORATION OF N EW JERSEY LASTING MACHINE Application filed September 10, 1931, Serial No.

o trated as applied to a machine of that kind,

but it is to be understood that in its more general aspects it is likewise applicable to machines for lasting the toes of shoes.

In machines of the above-mentioned charlfact-er the end-lasting wipers are operated by advancing them bodily lengthwise of the shoe and closing them toward each other laterally of the shoe. An object of the present invention is to improve, under some conditions of shoe manufacture, the results of the lasting operation performed by such wipers, especially at the sides of the shoe bottom at and near the forward ends of the wipers, and more particularly to avoid any undue dispiacement lengthwise of the shoe of the marginal portion of the upper materials in those locations. To this end the invention pro vides novel means for operating the wipers in such manner as to eliminate, at least for the most part, advancing movement of the wipers lengthwise of the shoe when operating on portions of the upper comparatively remote from the end face of the shoe, the construction shown being such that the wipers are advanced and closed simultaneously to Wipe the margin of the upper inwardly around the rear portion of the heel seat while only beginning to wipe it inwardly at the forward end of the heel seat, and are then further closed without advancing movement to complete the overwiping operation. The forward end portions of the wipers accordingly perform most of their operation on the upper without any bodily advance of the wipers lengthwise of the shoe. so that there is no danger of objectionable forward displacement of portions of the upper materials, in-

cluding the wings of the counter, near the shank portion of the shoe bottom. To operate the wipers in the above-described manner, the

machine herein shown is provided with members that are movable independently of each other to advance and to close the wipers respectively, these members, as illustrated, comprising slides which carry rolls engaged and operated by a single cam that moves the slides in such time relation to duce the desired results. The construction shown is further such that prior to the beginning of the simultaneous advancing and closing movements of the wipers over the shoe they receive advancing movement only, to bring them close to and, it may be, a little over the edge of the rear end of the heel seat.

The novel features of the invention will now be more particularly described by reference to the accompanying drawing and pointed out in the claims.

In the drawing,

Fig. l is a plan view of a portion of a heelend-lasting machine in which the invention is embodied, illustrating different positions of the wipers and associated parts in the course of the operation of the machine;

Fig. 2 is a diagrammatic View illustrating the shape of the Wiper-operating cam and its relation to the rolls that it engages; and

Fig. 3 is an end view of the cam member.

For purposes of illustration the invention is herein shown as applied to a machineof the type disclosed in Letters Patent No. 1,852,015, granted on April 5, 1932, upon an application of Jacob C. Jorgensen. As more fully disclosed therein, the machine comprises, for wiping the marginal portion of the heel end of an upper inwardly into lasted position over a sole or insole on a last, a pair of wipers curved to embrace the heel endof the upper and formed to extend forwardly at the sides of the heel seat at least as far as the beginning of the shank portion of the shoe bottom when the wipers are in fully advanced and closed positions. These wipers are supported on a member or slide 12 which is movable to advance them bodily lengthwise of the shoe, and by curved guiding connections 14 more fully disclosed in the above-mentioned Letters Patent they are mounted for swinging movements about an axis located near the rear end of the heel seat to close them inwardly toeach other as to pro-' ward each other laterally of the shoe. For imparting the swinging or closing movements to the wipers there are provided slides 16, one for each wiper, mounted on the frame of the machine for movements laterally of the shoe, each slide having an end portion 18 provided with a slot 20 in which is mounted a roll 22 carried by the adjacent wiper. The slots 20 extend lengthwise of the shoe to permit advancing movement of the wipers relatively to the slides 16. Each of the slides 16 carries a rack bar 2e engaged by a pinion 26 which is engaged and operated by a curved rack 28 formed'on one end of a bell-crank lever 30 pivoted at 32 on the frame of the machine, the other end of this lever having thereon a curved rack 34; engaged and operated by a rack bar 36. These various parts, as illustrated, are all substantially as disclosed in the above-mentioned Letters Patent.

I For purposes of this invention the two rackbars 36 are carried by a wiper-closing member or slide 38 which is operated independently of the wiper-advancing slide 12.

" The wiper-advancing slide 12 carries a roll 40 engaged and operated by a path cam 12 formed in a rotatable cam wheel A and arranged similarly to the wiper-operating cam shown in the above-mentioned Letters Patent. In the construction herein shown the wiperclosing slide 38 is provided with a roll 46 "engaged and operated by the same cam 42 that operates the slide 12. This cam, as shown in Fig. 2, has an inclined portion a whereby. operative movements are imparted to the wipers through the difierent rolls and slides. It will be observed that in the operative movement of the cam its inclined portion a first engages and acts on the roll 40 to impart advancing movement lengthwise of tlie 'shoe to the slide 12 and the wipers before it arrives in position to impart any movement to the slide 38. Thereafter, in the continued movement of the cam, its inclined por-' tion operates on both rolls 40 and 416 to impart simultaneous advancing and closing movements to the wipers. In its further movement the inclined portion of the cam ceases to operate the slide 12 while continuing its'operation of the slide 38, so that the wipers are closed inwardly toward each other without any advancing movement lengthwise of the shoe. With reference to the operations performed on the shoe, the construction is such that the wipers are first moved substantially half-way along their path of advance without any closing movements, thus bringing their wiping edges to the positions indicated by broken lines at b in Fig. 1 in which they may, as illustrated, slightly overlap the rear end of the heel seat. The wipers then receive simultaneous advancing and closing movements to wipe the margin of the upper inwardly around the rear portion of the heel seat while only beginning to wipe it inwardly at the forward end of the heel seat near the shank portion of the shoe bottom, their positions at the end of these movements being illustrated at 0. At this point they have received substantially half of their closing movements. After the wipers have arrived in these positions their closing movements are continued without any advancing movement to complete the overwiping operation at the sides of the heel seat, as illustrated at d. It will thus be seen that the wipers perform the greater portion of their operation on the upper at the forward end of the heel seat near the shank without any substantial bodily advancing movement lengthwise of the shoe. The portions of the upper materials, including the wings of the counter, which are operated upon by the forward end portions of the wipers are thus wiped inwardly over the heel seat widthwise of the shoe without danger, on any work, of objectionable forward displacement of the materials. This not only results in a well-lasted heel seat, but avoids the possibility of conditions such as might detract from the best results in the lasting of the shankportion of the shoe near the heel seat.

It will be evident from the foregoing description that the desired results are obtained without the necessity for any modification of the wipers themselves, which may be constructed as heretofore in heel-seat-lasting machines of the type disclosed in the Letters Patent referred to, or of other types, and that the changes necessary in such machines to accomplish the end in view are comparatively simple and readily effected. It will further be evident, as hereinbefore suggested, that in its more general aspects the invention is not limited to heel-seat-lasting machines, but is likewise'applicable to ma.- chines for lasting the toe ends of shoes in which it may, under some conditions, be utilized with desirable results.
