Patented Apr. 19, 1949 METHOD OF AND APPARATUS FOR LASTING FOOTWEAR Jacob S. Kamborian, West Newton, Mass.

Application December 16, 1944, Serial No. 568,471

35 Claims. (Cl. 12-1) This invention pertains to the manufacture of footwear and relates more particularly to an improved method of and apparatus for use in lasting shoes, the present invention being a further development of the invention set forth in the United States patent to Kamborian No. 2,251,284 dated August 5, 1941.

That patent discloses the employment of means, for instance a pair of helically ribbed rolls. for gripping the lasting margin of the upper and exerting such stress as to draw the upper snugly about the last, while, at the same time, tending to move the lasting margin in a direction substantially parallel to the edge of the sole, in other words setting up a relative movement of the shoe and the rolls; in combination with wiping means, e. g. a rapidly vibrating reciprocating wiper, which urges the stressed lasting margin inwardly across the edge of the sole into contact with the bottom surface thereof to which it is secured by suitable means e. g. by adhesive applied prior or subsequent to the upper drawing operation or by metallic fasteners.

The present invention embodies means whereby the underlying principles of the above patent are attained. One object of this invention is the provision of means whereby the shoe being lasted is held with the bottom of the sole in a horizontal plane while the gripping rolls rotate upon axes at an angle of the order of ten to fifteen degrees to the vertical. Another object of this invention is to provide means which will act upon the lastingimargin before it enters the bite of the gripping rolls and bring it into a plane substantially perpendicular to that of the shoe bottom. A further object of the invention is to provide an element positioned between the gripping means and the wiping means against which element the sole of the shoe being lasted is pressed by the operator,

over which element the lasting margin is foldedand by which element adhesive is introduced between the lasting margin and the sole so that the lasting margin will adhere to the sole when wiped into contact therewith, said adhesive being hot when introduced and having the property of setting quickly. A still further object of the invention is to provide as wiping means, two independently reciprocated blades so actuated and mounted that they move seriatim over the lasting margin and that one or the other at least of said blades is in contact with the lasting margin until the adhesive has set sufilciently to oppose any tendency thereof to separate from the sole, one or both of said blades being so mounted as to exert downwardly applied pressure upon the lasting margin. Other and further objects will appear from a consideration of the following detailed description of one embodiment of the invention and of the accompanying drawings wherein,

Fig. 1 is a plan view of the forepart of a shoe being lasted in accordance with the teachings of this invention, parts of the apparatus being in horizontal section;

Fig. 2 is a fragmentary elevation, showing the rolls by which the shoe upper is drawn closely about the last, the shoe being shown in transverse section and indicating the edge wall of the shoe and the plow by which the lasting margin is raised;

Fig. 3 is a fragmentary elevation looking in the direction of the arrow 3 in Fig. 1 illustrating the sequence of steps of the lasting operation and the relation of the lasting elements to the plane of the shoe, the latter being in vertical section;

Fig. 4 is a fragmentary elevation. partly in vertical section, illustrating the operation of the hold-down applicator;

Fig. 5 is a fragmentary side elevation, withparts in vertical section, illustrating one form of mechanism by which the lasting elements are supported and actuated; and

Fig. 6 is a plan and Fig. 7 a vertical section respectively of the wiping unit.

Figs. 1 to 4 inclusive of the drawings illustrate the lasting of a shoe of the type known in the trade as a California," force-lasted, or sliplasted shoe. Such a shoe comprises an upper [0, a wrapper ii secured to or constituting an extension of the upper to provide a lasting margin, a sock lining l2, the upper. wrapper and sock lining being Jointed as by a line of stitches l3, and a platform I l secured by adhesive or other suitable means to the sock lining. As shown at the right hand side of Fig. 1, the wrapper II is initially in a position extending substantially parallel to the upper ill. The assembled upper, wrapper and sock lining are pulled over a last l5 prior to the assembly of the platform therewith. Since the wrapper lasting operation is to be performed with the shoe upside down, the wrapper may, for convenience, be described as initially depending, and corresponding language will be employed in the description of the wrapper lasting operation.

The various elements by which the wrapper lasting operation is to be performed are, in chronological order, a plow 20 by which the depending wrapper H is raised or up-lasted, a pair of rolls 30 by which the upper I0 is stressed snugly enemas about the last I6 and the platform I4, a nozzlelike device 40 by which the platform I4 is held down and through which adhesive is supplied, and impact-wiping means 60 by which the lasting margin is wiped in and hammered down upon and secured to the platform I4.

The plow 20 is reciprocated, as indicated by the double headed arrow 2I (Figs. 2 and 3) to engage and raise successive portions of the wrapper into the plane of the bite of the rolls 30. The rolls 30 are continuously driven in opposite directions as designated by the arrows 3|, 32 in Fig. 1. Each roll is preferably provided with helically extended ribs 33 and the inner roll, 1. e.- the one over the platform is provided with a boss 34 against which the platform is held by the operator. (See Fig. 2.)

The device 40 will be designated a hold-down applicator because of the several functions thereof, as set forth above. The applicator 40 terminates in a toe 4 I, the base of which is, as shown in Fig. 4, substantially flat. During the lasting operation the shoe is held in position by pressing the platform against the boss 34 of the roll 30 and the base of the toe 4|. The shoe is preferably positioned with the edge of the toe substantially at the edge of the platform and the upper surface of the toe is inclined upwardly from the edge so that as the lasting operation proceeds the margin is bent over and in contact therewith, whereby the wrapper is turned smoothly over the edge of the platform and adhesive may be applied thereto as will be hereafter described. When the platform I4 is made of fibre, rubber or similar material, the operator, by pressing the shoe upwardly, causes the hold down applicator to compress the edge of the platform so that the wrapper will be bent smoothly over the edge as indicated in Fig. 4. The applicator 40 is provided with a central adhesive transmitting conduit 42 which terminates in an outlet passage 43 at the base of the toe H. 'A roller 44, in an outlet passage 45 in the upper surface, transfers adhesive from the conduit 42 to the inner face of the lasting margin as the latter moves thereover.

The final step in the lasting operation is performed by the wiping means 50, here shownas two blades SI and 52 which are independently reciprocated transversely over the lasting margin as indicated by the double headed arrows 53 and 54 on Fig. 1. The wiping means 50 are preferably so positioned that they act upon the lasting margin at an angle to the longitudinal axis of the shoe of the order of seventy-five to eighty degrees.

Various means for supporting and actuating the lasting elements may be provided. Fig. illustrates one such means which follows in general the construction disclosed in the above mentioned United States patent. A machine frame 60 suitably supported upon a bench or table (not shown) is provided with a head 6| which extends forwardly of the front wall 62 of the frame. Mounted in bearings in said head is a horizontal shaft 63 continuously rotated by any suitable means (not shown) within a casing or chamber 64. The portion of the shaft within the chamber is provided with right and left

hand worm threads

66 and 66 separated by a cam 61.

The plow 20 is integral with or mounted upon a rod guided for vertical'reciprocation within the head 6|. The upper end of the rod 10 is yieldably held in contact with the cam 61 as by a spring II and the cam is so formed that the rod I0 and its plow 20 are given one or more 4 complete reciprocations for each rotation of the shaft 63.

The rolls 30 are rigidly secured to the lower ends of shafts 60 and 0| provided at their upper ends with

worm wheels

32 and 93 which mesh with the

threads

66 and 66 respectively. The shafts 30 and 3| are Journaled in bearings so that they rotate freely. The shaft III is carried by a slide 34 so that, should occasion arise, it may be shifted forwardly from the shaft 90. This construction is similar to that set forth in the above patent.

The hold down applicator 40 is held in position by a clamp or strap at one end of an arm 9I mounted upon a flange 92 on the head 6|. Adhesive is supplied to the applicator from a tight tank or reservoir 93 suitably supported in the frame 60 and connected to the applicator by a tube 94. Mounted within the tank is a vertical pipe 96 the upper end of which terminates at the upper wall of the tank and the lower end of which projects below the bottom wall of the tank. Ports 96 in the pipe near the bottom of the tank admit adhesive into the pipe and port 91 connects the pipe to the tube 94. The lower end of the pipe 96 is closed by a removable plug 99 the upper surface of which is at the lower edge of the port 91. A plunger 99 normally positioned just above the ports 96 is carried at the lower end of a rod I00 which extends through a bearing ring IOI beyond the top of the pipe. The plunger 99 may be depressed in any-desired manner as for example by a lever I02 pivoted at one end upon a bracket I03 and connected at the other end by a link I04 to a treadle (not shown). The rod I00 is connected to the lever I02 by a stud I05 which is received in a slot I06. Suitable means such as a spring I01 are provided to return the plunger to its normal position.

The space in the pipe between the

ports

96 and 91 is preferably such that it will hold the amount of adhesive required to treat one shoe. Hence only a single complete depression of the plunger will be required during the lasting of each shoe. The preferred adhesive is of the type that will set quickly when exposed to the air. Various types of such adhesive are known, most of which are thermoplastic. In order to maintain the adhesive in condition, the tank 93 is provided with heating means I00, the tube 94 and the applicator are provided with an insulating jacket of any suitable type, a portion of which is indicated at J, and a supplementary heater I09 is provided at the toe H. The temperature to which the adhesive is raised may be varied according to the conditions present during the lasting e. g. material employed in the upper or platform under which the lasting takes place. Should it be found that the temperature of the adhesive is too high for the particular operation, a jet of cool air may be applied through a jet IIO (Fig. 1).

The blades 5| and 52 of the wiping means 50 are reciprocated by the rotation of a shaft I20 (Fig. 6) mounted in the frame 60. Fixed upon the shaft I20 are cams or eccentrics I2I and I22 enclosed by straps I23 and I24 upon rods I25 and I26 pivotally attached to the blades SI and 52, the members I2I and I22 being so designed and mounted as to cause the blades 5| and 52 to reciprocate in out of phase relationship. The outer ends of the rods I25 and I26 are supported by brackets I21 and I29 depending from plates I29 and I30 slidable in guides I3I and I32 fixed to the under face of the flange 92. Rigidly suspended from the head 6| are cam plates ill and Ill. Rolls I35 and I86 on the blades BI and 52 are held yieldably in contact with the cams as by springs I31 and I38. Hence, as the blades SI and 52 are advanced, the outer ends thereof are caused to press the lasting margin down firmly against the platform. It will be noted that the forward ends and the bottom forward edges of the blades are rounded to prevent any injury to the lasting margin. Since it is desired that the blades SI and 52 act upon the lasting margin at an angle to the axis of the shoe, it will be understood that the shaft I is similarly positioned.

The operation of the lasting machine will now be described, it being understood that the shafts i3 and I20 are rotating and actuating the various elements as herein above described. The shoe (comprising an upper, a wrapper and a sock lining duly assembled and pulled over a last and having a platform adhesively secured to the sock lining) is presented by the operator to the machine with the wrapper depending. The shoe is held with the platform ll firmly in contact with the boss 34 and the under face of the toe ll so that the shoe bottom is substantially horizontal. (See Figs. 2 and 3.) A portion of the wrapper is engaged and raised or up -lasted by the plow 20 so that it will enter the bite of the rolls whereupon the upper is drawn snugly around the last and against the edge wall of the platform and advanced as set forth in the above mentioned patent. The wiper blades 5| and 52 press the lasting margin down against the platform, the portion of margin between the rolls and wipers being bent over the upper face of the toe ll. Due to the composite motion of the blades, the lasting margin is both wiped and hammered down against the platform.

The operator, at the proper time, depresses the treadle and starts the flow of adhesive. The pressure exerted by the plunger 99 upon the adhesive in the line will break any film that might be formed in the mouth of the outlet passage 43, and the roller 44, being in contact with the lasting margin, is positively rotated thereby to insure delivery of adhesive to the lasting margin. As pointed out above a single depression of the plunger 99 will feed enough adhesive to insure the bonding of the lasting margin of each shoe.

Should additional adhesive be required, the operator can depress the treadle a second time until the lasting of the shoe is completed. Alternative to the described arrangement, provision may be made for establishing fluid pressure within the tank 93 and the depression of the treadie caused merely to operate valve mechanism to control the outflow of adhesive, which flow will continue so long as the treadle is depressed.

While means are disclosed by which adhesive is applied both to the lasting margin and to the platform, it will be understood that under certain conditions adhesive need only be applied to one of such parts and that the hold down applicator will be modified accordingly, as by omitting the roller 44 and applying adhesive through the outlet passage 43 or by omitting the outlet passage 43 and applying adhesive by the roller 44. Under certain conditions the wrapper may be uplasted by the operator before the shoe is presented to the machine. When this takes place the slide 84 may be actuated as set forth in the above patent to separate the rolls 30 so that the wrapper can be positioned therebetween, whereupon the slide is returned to its normal position 6 and the wrapper gripped between the rolls. The lasting operation is then completed as described above.

The essence of this invention resides in the provision and operation oi. the

lasting elements

20, 30, Ill and I0 and while one means for supporting and operating such elements is shown in the drawings and described in detail it will be understood that other means for supporting and operating such elements may be employed without departing from the spirit and scope of the invention.

This invention has been shown in the drawings and described herein as employed in the manufacture of shoes of the "California" type. It will be understood however that it is not limited thereto and is applicable to the manufacture of other types of shoes. The claims are accordingly so drawn. The term "lasting margin" used therein covers not only the wrapper herein described which constitutes an extension of the upper, but also the margin of the upper itself in case no wrapper isprovided and the term sole includes not only the platform herein disclosed but the insole, cushion or other intermediate sole.
