LASTING-MACHINE.

Specifuaation of Letters Patent.

Patented Sept. 29, 1914.

Application filed AugustlS, 1909. Serial No. 513,453.

To all whom it may concern:

Be it known that I, CHARLES DE MINICO, a citizen of the United States, residing at Portsmouth, in the county of Soioto and State of Ohio, provements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in theseveral figures.

This invention relates to lasting and nailing machines and is herein shown as em bodied in a machine of the type shown in United States Letters Patent No. 584,744, granted June 15, 1897.

An object of the present invention is to provide means for efi'ecting adjustments to control the angular relation of the plane of the shoe bottom to the several instrumentalities of the machine. A particular condition rendering this adjustment desirable is found in connection with the nailing instrumentalities. Experience has demonstrated that in lasting shoes certain angular relations of the plane of the shoe bottom to the direction of the nails or tacks is desirable by which the tacks are driven at an oblique angle to the plane of thetack receiving surface of the shoe. The angular relation of the plane to the machine is determined by the vertical position of the shoe bottom rest because the vertical position of the edge of the shoe is determined by the tack holder. Many modern lasts, however, particularly womens lasts, are rounded or arched at the shanks while they are fiat at the ball and toe. This throws the shoe out of proper angular relation to the driver at the shank so that the tacks are inserted at too great an angle to the plane of the shoe bottom and sometimes these tacks fail to hold the upper securely. 1

An important feature of this invention consists in the combination with tack insert-. ing mechanism and shoe guiding devices, of means under control of the workman to adjust said devices and mechanism relatively to control the angular relation of the tack tions of the shoe differing from one another have invented certain Imas do the shank and forepart of the lasts mentloned, or it may be employed to cause lnsertion of tacks in different angular directions in different portions of the shoe as Wlll be readily understood. As herein shown, the shoe bottom rest is adjusted and 1t w1ll be obvious that the adjustment of the rest takes place with relationto all the instrumentalities of the machine which have a definite position or path of movement and particularly with relation to the direction of advance of the wiper and the path of the grippers. Preferably means is provided for making definite degrees of adjustment and for securing the rest in adjusted position and the adjusting means is arranged so that it can be operated without interrupting the running of the machine. In the machine of the patent the bottom rest is a bar occupy ing an inclined relation to the direction in whloh the fastenings are inserted and one convenient way to adjust it for the purpose stated, is to shift it endwise in an inclined guideway although itymay also be moved vertically as is also shown in the accompanying drawings. 1

The foregoing and other features of the invention including certain combinations of parts and more important details of construction will appear more fully in connec tion with the following description of the illustrated embodiment of the invention and will then be pointed out in the claims. 7 Figure 1' is a side elevation of a portion of said lasting and nailing machine equipped with the present invention; Fig. 2 is a vertical longitudinal section; Fig. 2 shows another position; Fig. 3 shows in full and dotted lines the two positions of the bottom rest with relation to the other instrumentalities of the machine while the shank and the toe, respectively, of the shoe are being lasted; Fig. 4 is a modification in side elevation; Fig. 5 shows a further modification inn combined tack block and wiper 4 for laying the upper down upon the shoe bottom and presenting a tack in position to be driven to fasten the upper, the driver 5 and its actuatingmechanism, and the edge guide 6 may be substantially as shown in said prior pin and slot lifter patent and the machine is provided with a bracket 10to hold the bottom rest 12 which is used for positioning the shoe vertically.

In the construction shown in the main figures, the rear or left hand portion of the shoe rest has an endwise sliding engagement in a vertically inclined guideway in the bracket 10 to permit the shifting ,of the rest for vertical and horizontal adjustment. A latch 14 is pivoted to the bracket 10 at 15 and has a depending lug 16 adapted to drop down behind the rear end orcross-bar 13 of the bottom rest and hold the latter in its advanced position, that is, toward the right in the drawings. For releasing this latch to permit the bottom rest to be adjusted toward the left in the inclined guideway for raising its shoe engaging end, lifter 20 is pivoted to the rest at 21 and has 'an arm 22 extending rearwardly under the latch to raise the latch into the position shown in .Fig. 2 against the tension of a spring 23 located in a socketin the bracket as shown best in Fig. 2. A swinging arm 25 pivoted at its upper end as in Fig. 1 has a sliding raising and rest sliding with the latch lifter 2O arm is connected by a rod 30, see Fig. 1, with a rotatable block 32 which is pivoted on a vertical rod 34 and has an eccentric stud 35 to which the rod 30 is fastened. The block 32 has an arm 36 by which it may be turned freely upon the rod 34 to move the eccentrically located stud 35 and thereby, through the rod 30, actuate the swinging arm 25.

Assuming the parts to be in the positions shown in Fig. 2 with the bottom rest retracted toward the left, a movement of the swinging arm 25 toward the right will act connection at 2t and this swinging through the lifting device 20 and the pivot to the rest 12 pin 21 to slide the bottom rest toward the right. l/Vhen the bottom rest has moved to the right far enough the projections 16 of the latch 14 will drop down behind the rear v cross-bar 13 of the bottom rest and hold the rest against retraction. WVhen it is desired to move the rest to'the left, the lever 36 and connected parts will be reversely actuated and the swinging arm will turn the lifting device 20 about the pivot pin to lift the projection 16 of the latch from behind the cross bar 13. Continued movement of the swinging arm to let will then transmit movement through the. lifting device to the bottom rest for sliding it toward the left.

In F 4 a slightly different con is illustrated in which the latch 1411s igidly fastened on the swinging arm 25 and has a beveled end on its depending arm which wedges the bottom rest 12 forwardly when the arm 25 is pulled to the right as shown in dotted lines. The arm 25 is connected by the pivoted lifter 20 By varying the inclination of the guideway in the bracket through which it is adjusted the movement may be made more or less vertical or horizontal or it may be made altogether horizontal and in Figs. 5 and (3 a modification of the adjusting mechanism is shown by which the movement given to the bottom rest is vertical. In this arrangement the guide for the rest is formed by one side of the bracket 10 which is embraced by lips 40 of a vertical arm 43 which carries the bottom rest 12. A bolt 42, extends loosely through a slot in the bracket and into the arm 43 to confine the arm and rest in place. By varying the direction of the guldmg faces and the slot in the bracket pressure from the shoe.

The block 32 is provided with a clamping screw by which it can be fastened to the vertical rod 34 if desired. This rod has also fast upon it a block 38 which is opcratively connected to the tack supplying mechanism for shifting the latter to change the kind of tacks and also this vertical rod is connected with means to control the length of the tack inserting movement of the driver all as fully explained in said United States Letters Patent No. 584,744. When the rest shifting'block 32 is fastened to the rod 34 the rest and the tacking mechanism are simultaneously adjusted.
