SHOE SUPPORTS FOR LASTING MACHINES Filed April '7, 1.961 4 Sheets-Sheet 5 June 26, 1962 E. A DESCHENES SHOE SUPPORTS FORLASTING MACHINES 4 Sheets-Sheet 4 Filed April 7, 1961 ration of New Jersey 2,

Filed Apr. 7, 1961, Ser. No. 101,426 6 Claims. (Cl. 12-125) This invention relates to shoe supports and is herein illustrated as applied to a machine for lasting the heel ends of shoes of the type wherein a rib extends around the heel end of the insole and the lasting margin of the upper materials is secured to the insole rib and feather by means of an adhesive. It is to be understood, how ever, that the invention is not limited in utility to application in a machine of the exact mechanical construction shown or to'the lasting of the heel ends of shoes of the particular type mentioned. v

The lasting of the heel ends of shoes in which an insole rib extends around the heel end of the insole may conveniently be effected by means of a lasting machine constructed generally in accordance with the disclosure of United States Letters Patent No. 2,982,980, granted May 9, 1961, inthe names of Joseph 0. Faneuf, Richard M. Elliott, and Daniel E. Chaplin, but having heel seat wipers which are adapted to be advanced along a linear path and at the same time closed to wipe the lasting margin of the upper materials at the heel end of a shoe inwardly over the feather and to press the lasting margin against the upstanding insole ri'b at the heel end of the shoe. Thereafter, as pressure is also applied to the upper materials in a direction extending heightwise of the shoe, the lasting margin of the upper materials is secured in lasted position by a suitable adhesive previously applied to the lasting margin of the upper and/ or marginal portion of the insole. In order to adapt a machine of this type which is intended for use in lasting the toe ends of shoes for the lasting of the heel ends of shoes, the shoe supporting mechanism previously provided and which is described in detail in United States Letters Patent No. 2,934,774, issued May 3, 1960, on an application filed November 25, 1958, in the names of Andrew G. Gilbride and Adelbert W. Rockwell, In, is replaced by a shoe supporting mechanism which is in general similar to that disclosed in United States Letters Patent No. 2,059,241, issued November 3, 1936, on an application filed April 19, 1935, in the name of Jacob C. Jorgensen.

In accordance with the object of this invention, the

- shoe support is modified to provide for adjustment of the heel end of the shoe thereon laterally with respect to the path of advancing movement of the wipers so that the insole rib at the heel end of the shoe may be readily and accurately centered with respect to the path of movement of the wipers. With this object in view, in the herein illustrated shoe supporting mechanism, which comprises a spindle mounted in the machine frame for rotation about an axis substantially perpendicular to the plane of the wipers, the last pin, which is preferably formed integrally with the spindle, is disposed eccentrically with respect to the axis of rotation of the spindle, while the toe rest is carried on an arm which, in turn, is mounted on the spindle for rotation relative thereto against the resistance of a 'fr-ictionally acting means. Thus, by grasping a handle conveniently provided on the spindle with one hand, while preventing rotation of the arm by engagement of the arm with his other hand, the operator can effect rotation of the spindle and hence of the last pin, against the resistance of the frictionally acting means, and thereby shift the heel end of a shoe mounted on the pin laterally with respect to the path of advancing movement of the wipers. Having thus adjusted the heel end of the shoe to center the heel end of the insole accuratei is 1y with respect to the path of advancing movement of the wipers, the operator may then advance and close the Wipers, "while still preventing rotation of the arm, and hence of the shoe, so that the wipers will press the lasting margin of the upper materials against the insole rib with an even pressure around the heel end of the insole.

The above object and feature of this invention will appear in the following detailed description of the em bodiment thereof shown in the accompanying drawings and will be pointed out in the claims.

in the drawings,

FIG. 1 is a view, in perspective, of a lasting machine provided with a shoe support embodying features of this invention; 7

FIG. 2 is a plan view of the machine shown in FIG. 1;

FIG. 3 is a plan view at an enlarged scale of a portion of the machine and showing a shoe mounted on the shoe support;

FIG. 4 is a view in vertical section substantially on line IVIV of FIG. 3 and' looking in the direction of and thus has a wiper head 10 containing the usual wiper 68. The spindle 62 also passes through'a bore in the operating cams, not shown, which are adapted to be operated by'means including a hand lever 12 having a hand grip 14 thereon to advance and to close a pair of heel seat wipers 16, 16, see FIGS. 2 and '3. Also,

the wiper head is carried by a table 18 which is mounted for swinging movement about a trunnion shaft 20 to raise or lower the wipers by means including a link 22,

lever 24, link 26, and a foot treadle 28, the arrangement being such that when the righth'and portion of the treadle is depressed, the table 18 and the wiper head 10 will be swung downwardly, against the yield-able resistance provided by a collar 30 and a spring 32 associated with a shaft 34.

At its lower end, this shaft is threaded through an car mechanism (not shown) is provided for moving the wiper head downwardly against the yieldable resistance of the spring 32, thus to cause the wipers 16, 16, after they have been advanced and closed, to exert a bedding pressure on the lasting margin of the upper materials, in response to the operation of a control button 46 mounted in the hand grip 14. i I

Referring to FIG. 4, and especially to the improved shoe support, there is rotatably mounted in a bore 60, formed in a portion of the machine frame 38, and directly beneath the wiper head 10, a spindle 62 having an offset upper end portion 64 of reduced diameter and shaped to provide a' shoulder 66. Secured in and extending up-- wardly from the portion 64 of the spindle is a last pin split end portion 72 of an arm 74 whichextends forwardly of the machine, as shown in FIG. 1. Relative rotation between the spindle 62 and this arm is frictionally resisted to a greater or lesser extent in accordance constructed generally in accordance with the disclosure or" the above-mentioned Jorgensen patent.

Referring to FIG. 3, after the operator has placed a shoe S, comprising an upper U and insole I, having a rib R, assembled on a last L (FIG. 4) on the last pin 68, with its forepart resting on the shoe rest 82, he will first swing the arm 74 and shoe with his right hand to bring the longitudinal center line of the heel end of the shoe into parallelism with the linear path of advancing movement of the wipers 16, 16. Now, if the last pin hole 84 has been accurately centered with respect to the heel end portion of the bottom of the last and the insole I accurately located on the last, the heel end of the insole should also be centered with respect to the wipers, i.e., thelongitudinal center line of the heel end of the insole will coincide with the linear path of advancing movement of the wipers. However, because of inaccuracies in the drilling of the last pin holes and/or carelessness in screw 76, will shift the heel end of the shoe laterally with respect to the linear path of advancing movement of the wipers until the heel end of the insole is located in the desired central position. Now, when the wipers 16, 16 are advanced and closed to wipe the lasting margin of the upper materials inwardly over the feather and to press this lasting margin inwardly against the rib R of the insole, see FIGS. 3 and 4, the pressure of the wipers will be exerted evenly against the rib all around the heel end of the shoe, thus avoiding any tendency for the ribs to be overstressed or otherwise distorted by the application of unequal pressure thereon.

As indicated above, by suitable manipulation of the hand wheel 42, the wiper head 110 may be adjusted upwardly or downwardly to accommodate shoes of different sizes. To facilitate such adjustment, especially where there is a rather wide variance in the heightwise. dimension of the heel end of the shoes being lasted, a spacer bar 90, having a semicircular recess 92 adapted to em- I brace the spindle 62, FIG. 5, is pivotally mounted on the frame38 by means of a pin 94, FIG. 2. As will be apparent, when the arm 74 and spindle 62 are lifted up, this spacer bar may be swung in a counterclockwise direction, FIG; 5, and thus inserted between the arm '74 and upper side of the frame 38, thus to hold thespindle and arm in an elevated position.
