Specification of Letters Patent.

Application filed May 21, 1913., Serial No. 235,865.

To all whom it may coiiccm:

Be it known that I, Anatole) Bonnenors, a cit zen oi: the United States, residing at Swampscott, in the county of Essex and EState of Massachusetts, have invented certain ln'iprovementsin Machines for Mounting Shoes on Lasts, oi which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawingsindieating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes for mounting shoes on lasts. Such machines are of particular utility in the manufacture of turn shoes for mounting the shoe on the second last after the shoe has been turned,.

but it will. be evidentfrom a consideration of the construction and manner of operation oi. the machine herein shown that the ini ention not limited in utility to the manufacture of shoes of this particular type.

An object of the invention is to provide a machine of improved construction bythe use of which a shoe may be mounted on a last in an expeditious and effective manner with comparativel); little effort upon I the part ot the operator and without injury either to theshoe or to the last. An. important feature of the invention consists in novel means for working a shoe over a last by engagement with the shoe. The construction illustrated as an embodiment oi this feature comprises a band for embracing the heel end.

portion oi the shoe and means for closing the hand upon the shoe and tor operating: it

to work the heel end portion of the shoe smoothly over the last. The construction shown comprises also novel mechanism for operating the shoe engaging: means, whereby the operator. bv movement ot his foot, is en abled to move the shoe engaging means into or out of engagement with theshoe at will and also'to impart to said meansmovernents for working; the shoe over thelast.

It further feature otthe invention com- I prises a novel construction and arrangement.

oi means for forcing a last into a shoe in l combination with means for workin the shoe over the last. Still other features are to be re nixed in novel means enforcing a last into a shoe, novel means for, guiding the last in its n vemcntinto the shoe", novel means for positioning the shoe and for supchineiin' which the invention is embodied withportions broken away to illustrate the lntQIlODCODStILiCtIlOIl;

Fig. 2 is a view in side elevation, and partially in'vertical section, of a portion of the machine shown in Fig. 1; and i i 1 Fig. 3 is view similar to Fig. 2 of a portion of the machine, illustrating the positions of the parts at a different stage in the operation of the machine.

The machine herein shown comprises a,

column 2 adapted to stand upon the door, the column having at itsupperjend ahori zontal table 4 upon winches secured a plate l t li'iitillte d Nov. 23, 1920.

6 to provide a support for, the tforepart oi'ii a shoeinto which alast is to be inserted; Upon the plate 6 there may be positioned a sheet ofcomparatively yieldahle material 8 such as leather orrubber to prevent injury to thesurface of the sole during-the operation of. forcing the last into the shoe.

Seciired to the column 2 is a bracket 10 whichsupportsa plate 12 the upper surfs ce oi? which is hollowed out to adapt liljlfiiillfit to serve as a mold see Fig. 2) for shaping the heel seat portion of. the sole as the last is Forced into the shoe, The bracket 10 is provided with a vertical slot 14 which in cooperation w1th. a seeurin bolt 16 permits the bracket and the plate to be adjusted vertically, The bracket is preferably positioned, as shown. to sup iort the heel end portion oi the shoe ahigherelevation than the forenart, the rear portion of the T latively to the t0re[ shoe being: thus liite part to si'lbstantiallv the same extent as it is in the completed shoe by theactionof the.

attarhedflieel. By positioning: the shoe in this mannerwith its sole inclinedidownweirdly-toward the toe end, the operation of forcing! the last into the shocin the manner hereinafter explained is greatly facilitated.

Mounted for movement vertically in a bearingls on a bracket 20 secured to or formed integrall r. with the column Qis a rod .22hi1pon upper end of w hichiis ting the last to tip relatively 'during its movement into the shoe.

mounted an arm 24 which carries a last engaging spindle 26. "The diameter of the spindle 26 is greater than the; normal diameter of the usual socket or spindle hole a in the heel end portion of a last, and at its lower end the spindle is rounded in substantially semi-spherical form to permit it to seat within the. upper end of the socket a and thus to maintain an engagement with the lastin a definite location while permit to the spindle The spindle 26 has threaded engagement with the arm 24 to permit it to be adjusted vertically in'conformity to different conditions encountered in operating upon shoes of diff ferent sizes and styles. In order to permit accordance with the location shoe and the last or of tion 'of the spindle hole in different lasts the spindle 26 to be readily positioned in of the hole a in the last irrespective of the length of the variations in the posiand also to permit'the spindle to remain in engagement with the. last in the same location continually during the movement of the last'into the shoe, provision is afforded for movement of the spindle relatively to the rod 22 in directions lengthwise of the shoe. In the construction shown the arm 24 is swiveled upon the upper end of the rod 22,

thearm' carrying a set screw 28 which en- "gages in'a'n annular. groove 30 in the rod to afford an operative connection between the rod and the arm while to swing laterally; I V "For the purpose of lmparting operating permitting the arm movement to the rod 22 to force the spindle 26 downwardly, the rod is connected at its for . "-lower end to a and the spindle play of the lever 32 to "tojeffect engagement or disengagement of the plate 40 withthe teeth of'the plate 38. y means of this constructionthe lever 32 may beloeated insuchmanner as to hold the spindle 26 against upward retractive movement after the parts have been operated to force the last either partially or entirely into theshoe, as will be hereinafter more fully explained. V V r I I In order to assist in positioningthe shoe the operation of the machine, and also to insure against forward movement of the shoe, the machine is provided with a laterally curved shoe positioning member 42 which is supported upon a. bracket 44 on the table 4 in position to project in front of the toe end of the shoe. T he member 42 is connected to the bracket 44 by means of a. hinge 46 which permits the member to rock laterally and thus to conform readily to the location of the toe end of the shoe, whether the shoe be a right or a left. The bracket 44 is secured to the table 4 by means of a bolt 48. this bolt extending through a. slot 50 in the bracket which permits the shoe positioning member 42 to be adjusted in directions lengthwise of the shoe, in order to adapt the machine to operate upon shoes of different sizes. In addition to the mom- -er 42, the machine is also provided with shoe positioning members 52 which are arranged to engage the shoe at the opposite sides of the forepart. these members being supported for rocking movement upon brackets 5-4 in substantially the same manner in which the member 42 is supported upon the bracket 44. The brackets are secured adjustably to the table 4 in substantially the same manner as the bracket 44 and permit the members 52 to be spaced different distances apart for shoes of different widths. The members 42 and 52 are preferably faced with yieldable material 56 such for example as leather or rubber in order to insure against injury to the surface finish of the shoe.

In order to assist in guiding the last into the shoe during the downward lTlOVOIl'lQHlJ of he spindle 26 effected in the manner hereinbefore explained, the machine is provided with a member 58, herein termed a shoe horn. which is preferably formed of metal or of similar resistant material. having a smooth surface along which the rear end portion of the last may slide as it is forced into the shoe, this member being curved laterally in approximate conformity to the lateral curve of a last and shoe around the heel end portion. In order to position the member 58 for convenient use andv to permit it to be readily withdrawn from the shoe when required, it is connected by means of a flexible strap 60 to an arm 62 carried by a pivot rod 64 which is mounted to turn in a lug on the arm 24 and is provided at its opposite end from the arm 62 with a second arm 66 adapted to serve as a handle. By swinging the arm 66 the arm 62 may thus be operated to pull the horn 58 out of the shoe whenever the operator so desires.

Positioned at the rear of the heel end portion of the shoe, as located upon the support ing plate 12, is an end embracing band comprising a portion 68 which ma be formed of rubber or other flexible material adapted to be wrapped about the heel end portion of the shoe in frictional engagement with the upper, the rubber strip 68 in the consi'r tion shown bein secure to a curved strin and thus lock the lever and its connected parts against retractive upward movement. In order to complete the relasting operation with respect to the rear end portion of the shoe and cause the upper to be drawn smoothly and free from wrinkles over the heel end portion of the last, the operator will then place his foot upon the rest 114 and by a direct downward pressure, without rocking the member 114, depress the treadle lever 96 to swing the heel band toward the shoe and wrap it about the heel end portion of the shoe in the manner hereinbefore explained. \Vhile maintaining the pressure upon the treadle to hold the heel band tightly about the shoe, the operator will then rock the member 114 rearwa-rdly about its pivot 116 and thereby impart an upward movement to the heel band in frictional engagement with the upper materials to pull or draw the upper tightly over the last while the last is restrained from upward movement by its engagement with the spindle 26, If desired, the operator may repeat this'operation of the band upon the shoe, causing it to release and then to reengage the shoe and wipe the upper upwardly as many times as he desires. This operation of the heel band upon the shoe may be performed if desired before the last has been entirely forced into the-shoe by the action of the spindle 26. In case it is noted, for example, during the operation of forcing the last into the shoe that there is a tendency for the upper at the rear portion of the shoeto be wrinkled, the treadle lever 32 may be located in an intermediate position and the heel band then operated in the manner hereinbefore ex lained to work the upper over the last. Sidbsequently the treadle '32 may be further depressed to complete the operation of forcing the last clownward into the shoe, after which if desired the heel band may be again operated to draw the upper finally in a smooth and unwrinkled condition over the last. It will be evident that the shoe horn 58 may or may not be wtihdrawn prior to the operation of the heel band or may be manipulated simultaneously with the band to work the shoe over the last.

During the final stage of the depressing movement of the spindle 26, whereby the lastis forced downward with firm pressure upon the solo at the heel end portion, the mold 12 becomes effective to shape the'heel seat portion of the sole substantially as desired for the subsequent attachment of the heel, and thus, in a measure at least, to eliminate the necessity for any subsequent shaping action upon this portion ofthe sole.

While the heel band and its operatingmechanism for use in drawing the heel end portion of a shoe smoothly and free from wrinkles over a last are herein shown as part of a machine for use in mounting shoes on lasts, it will be evident that this portion of the structure involves features of utility irrespective of the particular charactor of other attendant mechanism or of other operations which a machine including such structure may be adapted to perform, and the drawings and description are therefore to be regarded as merely illustrative and not as implying a limitation with respect to the scope of the invention.
