' LasnNe-macnmn Specification ofLetters Patent.

Application filed June 13, 191%. Serial No. 239,760.

To all whom it may concern:

" Be it known that 1, JOHN B. HADAWAY, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the followingdescription, 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 lasting shoes and more particularly to machines for lasting shoes in which the upper is secured to the bottom ortion of the shoe in the lasting operation by the use of cement as, for example, in the manufacture of fabric shoes which are to have rubber outsoles vulcanized to them.

In the manufacture of shoes having vulcanized soles, the innersole, in accordance with the usual practice, is formed of a rubber compound known generally as rag stock. This innersole is relatively thin and pliable and its outer surface is rendered tacky by the application of a suitable rub-- ber compound. The upper of the shoe, when prepared for lasting, has the inner face of its margin coated with rubber cement which, when brought in contact with the tacky surface of the innersole, adheres firmly thereto. Heretofore, shoes of this kind have been last ed almost entirely by hand, the upper being merely bent over the edge'of the last against the innersole by a rocking or wiping motion of the hand, particularly of the thumb. This hand work is exceedingly laborious and, by reason of the consequent fatigue of the operator and the general unreliability of the hand operation, uniform results in the course of a. days work are difficult to obtain. As a consequence, the manufacturer finds in his product a large number of reject shoes which have to be disposed of, if at all, at a greatly reduced profit or at a loss. Furthermore, it is practically impossible for an operator to apply with his fingers any substantial tension to the upper to shape it to the contour of the last since the effort required for the mere working over of the upper properly upon the innersole taxes the endurance of a person of ordinary strength when kept up continuously in the days work. An object of this invention is to provide a machine for doing the work more rapidly than it can be done by hand and for performing the stretching and overlaying of the upper more reliably and effectually than is possible by human agency alone.

A feature of the invention consists in an organization including wiping means for overlaying the margin of a shoe upper upon the bottom of the sole, which means has continuous pressing engagement with the overlaid upper margin throughout its width, and means for moving the wiping means continuously in a direction inwardly of and over the shoe bottom. As shown herein, the continuously pressing or wiping means may be of fabric.

Another feature of the invention consists in an organization including continuously effective overwiping means and means which may also be continuously effective for upwiping the upper at the side of the shoe. As shown herein, the machine is organized for lasting the shoe progressively and the continuously effective upwip-ing means is arranged to act in advance of and also simul taneously with the continuously effective overwiping means. In the construction shown, two belts of similar construction are provided, one constituting the upwip-ing means, and the other the overwiping means. The upwiping belt is arranged in advance of and offset from the overwiping belt so that after a portion of the upper is wiped upwardly against the side of the last, the margin of that portion is immediately thereafter engaged by the overwip-ing belt and laid against the bottom of the shoe. The belts are preferably arranged to be actuated positively and at the same speed.

An upper can be more effectively worked over a last by a varying or pulsating force than by a continuous pull or drag of sustained intensityf Accordingly a feature of the invention consists in means for imparting a varying or pulsating quality to the action of the Wiping means during the opera tion of working the upper into lasted position. This result may be obtained, as in the construction shown, by wiping means which consists of a continuously moving means,

for example, a belt upon which are arranged protuberances which successively engage the upper and impart the pulsating effect to the .action of the belt in the conformation of the upper to the last. Between the protuberanc'es or projections the belt itself acts upon Patented Dec. 2th, 1921i. 7

' the upper and the upper is therefore treated,

alternately by a projection and by the intervening section of the belt.

- Preferably the belt or wiping means has rigid and yielding portions which act in turn upon the upper to treat the upper with varying degrees of intensity, for example, successively to hard and light wiping actions. As herein shown, the wipin means comprises a continuously driven %)elt of yielding material which is provided on its acting face with hard protuberances which treat the upper to successive hard wiping acpulley is arranged at the side of the shoe 1 to support the lower portion of the upwiping belt and another pulley is located over the margin of the shoe bottom to hold the overwiping belt in engagement with the upper. These pulleys are preferably grooved to accommodate the protuberances upon the belts and are provided with means shown as flanges to prevent relative dis placement of the belts and pulleys due to the. drag of the shoe upon the belts as it is fed in either direction. It will be observed that by this organization either belt constltutes a rest or work positioning means for locating the work with relation to the other belt, the pulley at the side of the shoe supporting the belt for location of the work with relation to the overwiping belt and the, pulley located over the margin of the bottom of the shoe supporting the overwiping belt for location of the shoe relatively to the upwiping belt. Preferably, however, alshoe rest-is provided in addition to the "pulley and belt over the margin of the shoe bottom for positioning the shoe in proper relation to the wiping means and the rest may, as shown, he yieldingly mounted to allow varying intensities of overwipmg effect to besecured by variation of the pressure with which the shoe is upheld aga nst the rest and hence against the overw1 lng means.

nother feature of the invention con sists in means forrelatively disposing the operating portion of the upwiping belt which is leaving the pulley at the side of the shoe and the operating portion of the overwiping belt which is approaching the pulley over the bottom of the shoe at an angle which approximates the angle between the side of the last and the bottom of the justably to the machine frame.

last so that the operating portions of the upwiping beltwill be held in" engagement with the last at the side of the shoe adjacent to the bottom and the operating portions of the overwiping belt will engage the upper throughout the width of the overwiped margin of the upper. Preferably the pulleys are arranged for vertical and lateral adjustmentto enable the angle between the said portions to be varied. This provision for adjustment of the pulleys also enables the field of action of the belts vertically at the side of the shoe and laterally over the shoe bottom to be varied and also enables the area of the upper treated by the side wiping belt and the area treated by the overwiping. belt to be increased or diminished. As herein shown, the operating portions of the belts are carried over idlers which are arranged for adjustment to maintain the belts tight when adjustments of the pulleys-adjacent to time operating portions of the belts are mwc.

These" and other features of the invention will appear more fully from the following detailed description when read in connection with the accompanying drawing, and will be pointed'out in the appended claims.

In the drawing 1 'iFigure 1 iso. side view of the machine showing the shoe in section, and

i Fig. 2 is a perspective view showing the operative parts of the machine in their relatipn to a shoe being operated upon.

Referring to Fig. 1 of the drawing, the numeral 2 indicates the frame of the machine in which is journaled a shaft 4 having a pulley t to which power is applied Fixed to the shaft 4 isa wide driving pulley '8 upon which are arranged'two separate belts 10 and 12. The belt 10 passes from the pulley 8 downwardly to an idler 14 mounted on a bracket 16. The bracket is slotted at 18 and is secured to the frame by a bolt 20 which passes through the slot 18 and through a slot 22 inthe frame. By means ,of the bolt 20 and slots 18 and 22, the bracket 16 may be adjusted to tighten the belt 10. From the idler 14 the belt 10 passes to a pulley 24 located opposite the side of the shoe. The pulley 24 is mounted on a bracket 26 slotted at 28 and held to the frame 2 by a bolt 30. From the pulley 24, the belt passes I to a wide idler 32 and thence back to the driving pulley 8. The belt 10, as it' passes up over the pulley 24, acts against the upper at the side of the shoe to wipe it toward the shoe bottom. 7

The belt 12 passes from the driving pulley 8 to a pulley 34 located over the shoe bottom and adjacent to its edge. The pulley 34 is mounted on a bracket 36 having a slot 38 through which the bolt 30 passes and holds the bracket 36 as well as the bracket 26 ad- From the pulley 34 the belt 12 passes to an idler 40 adjustably held by its pivot bolt 42 in a slot 44 formed in an overhanging portion of the frame 2. Thence the belt 12 passes over the wide idler 32 back to the driving pulley 8 by the side of the belt 10. The pulleys 24 and 34 are provided with flanges, as shown, to prevent lateral movement of the belts in response to the drag of the upper as it is moved past the belts during the lasting operation. I a

:Fixed to the frame 2 above the shoe is a guide 50 in which is a sliding block 52 having a lug 54 which extends through a slot 56 in the guide 50. A compression spring 58 between the bottom of the guide and the sliding block 52 normally holds the lug 54 against the lower end of the slot 56. A cap screw 60 is threaded into the lug 54 and is embraced by an open slot 62 in a shoe rest member 64. This member may be adjusted vertically or laterally of the shoe and held rigidly to the lug 54 by tightening the screw 60. The member 64, however, may yield vertically against the spring 58. The lower end of the member 64 is formed, as shown, to engage the bottom or sole of the shoe locally at a point substantially beneath the axis of the pulley 34. The member 64 is cut away on its inner edge .to avoid the possibility of its interfering with the overlaying of the upper margin against the shoe bottom.

The belts are preferably composed of textile material and may, as shown herein, be made of a plurality of strands of cord arranged side by side. While the use of fabric or cord belts alone is contemplated, it is perhaps preferable to employ belts which are provided at short intervals with protuberances, for example, metallic bands or clips 68. These clips are firmly fixed to the belts by being compressed into the material of the belts and are arranged at regular intervals. Toaccommodate the clips, the driving pulley and preferably all the pulleys, are provided with grooves which the clips engage as they pass over the pulleys. The clips and grooves provide, of course, means for actuating the belts positively from the driving pulley without slippage.

The pulleys 24 and 34 may, by loosening the bolt 30, be adjusted to vary the angle between the operative portions of the belts 10 and 12, for example, to cause the angle between them to approximate the angle between the side and bottom of the last. The

pulleys 24 and 34 may also be adjusted to vary the length of the operative portions of the belts, that is, the length of the. belt 10 from the pulley 24 to the point where it crosses the other belt or the length of the belt 12 from the point of crossing to the pulley 34. In this way the length of the wi ing operation of either or both belts may be varied. The slots 22 and 44 enable the slack of the belts to be taken up whatever the adj usted position of the rolls 24 and 34 may be.

In the operation of the machine, a shoe prepared for lasting is held against the rest 64 with its side against the belt 10 which acts to wipe and draw the upper upwardly at the side of the shoe toward the last bottom. The shoe is now pressed upwardly, the rest 64 yielding to allow the belt 12 to come into wiping contact with the upwardly extending margin of the upper and wipe it into contact with the margin of the innersole where it is held by the cemented surfaces. The shoe is then moved transverselyof the belts lto cause successive port-ions of the upperto be treated first to an upwiping action by the belt 10 and then to an overwiping action by the belt 12. 'When these operations have been performed about the periphery of the shoe, it is ready for the application of an outsole.
