LASTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 247,625, dated September 27, 1881.

Application led August B, 1881.

of Rochester, in the county of Monroe andy State of New York, have invented a new and Improved Boot and Shoe Lasting Machine,.of

l which the following is a specification.

This invention is designed as an improvenient on the lastingmachine for which Letters Patent No. 236,218 were granted to me January 4, 1881; and it consists in making thelastseat, toe-rest, clamp-suspending hooks, pressing-bolts, levers, and certain other operating parts adjustable, whereby the machine is more readily adapted to shoes and boots of various sizes, all of which will be hereinafter described.

-In the accompanying drawings, Figure 1 is a partly-sectional side elevation of the machine with parts broken away to exhibit other parts. Fig. 2 is a sectional elevation of the same on line a x, Fig. 1. with parts broken away to exhibit other parts.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the frame ot' the machine, and B a longitudinally-slotted bar extending centrally across its bottom and forming part thereof. The standard C' of the seat O for the heel of the last D is adjustahly held in place so as to be moved along the bar B by its spindle a', which projects through the slot bin the bar B, and has anut, c,on itsend. This seat O has a downward-proj eeting spindle, a, that is adjustably held in a corresponding socket, a2, in the standard O by a set-screw, a3; hence it will be seen that the said seat O may be adjusted longitudinally and vertically by means of thenut aand set-screw a3. The standard E of the seat E for the toe of the last D is also held in the bar B so as to be longitudinally adjustable by its spindle d and nut d',- and said seat E has a concave face, so as to fit about the toe of the last D, as shown in Fig. 1, and has a downward-projecting spindle, d2, that is held in a corresponding socket, cl3, in the standard E', by a set-screw, d4; and said seat E is preferably covered with leather or other soft material, as indicated at d5, to prevent injury to the shoe-upper D', that is shown on thelastD. The seats O E may be approached to or separated from each other to adapt them to lasts of different sizes, and may be verti Fig. 3 is a plan of the same (No model.)

cally adj usted for the same purpose. A standard, F, is also held in the slot of the bar B by spindlefand nutf, and in the socketf2 of this standard F is adj ustably held by set-screw f3 a fork-headedspindle, F2, in the head of which a lug, F3, is held on a horizontal pin,f4. On vertical pins g g, that are held in the inwardprojecting end of this lug F3, are pivoted the levers Gr, so as to movein horizontal planes. These levers G consist of' metallic bars inwardly curved to coliform with the side outlines of the last D, near the bottom thereof, and they are also curved flatwise to conform in a measure with the curve of the bottom of thelast D. rIhese levers Gr are of sufficient length for their rear ends, which are prolonged into handles, to rest on a vertically-adjustable cross-bar, G', of the frame A, as shown, whereby they may he held at any desired vertical inclination, and are so hinged on the pins g g that they can be closed about the last D and leather D', and can be opened apart to permit the easy removal of last D and leather Dl that is stretched upon it. A clamp, g2, slipped over the ends of the levers Gr, holds them together about the last and leather D D.

H is a dat metal plate, called a templet,77 of the general shape of the bottom of the last D, and provided with holes 7L h, around its edge for the reception of the screw-hooks H', that y suspend the clamps I, which hooks H' and clamps I are vertically adjustable by means of nuts It on the ends of the former, as shown, whereby more or less tension can be applied at any point of the leatherlD'. Said templet H is longitudinally slotted, and is provided on its upper surface with lugs m m, by means ot' which it is suspended on pins m m from rods K, which extend up through the slotted crossbar A2 in the top of the frame A, and have their upper ends-pivoted to levers L, that are, in turn, pivoted or fulcrumed on pins u in the tops of the standards M, which are adjustably held by their spindles fn and nuts u2 on the slotted bar A2. To the long arms of these leversL are pivoted rods L', that have their lower ends slotted, as shown at o, and are extended down through the longitudinal slot p of the bar A2.

A shaft, O, journaled in hangers O', extends longitudinally through the frame A a little be- ICO low and at one side ofthe bar A2, and on this shaft O are loosely Xed two arms or cranks, O2, whose ends are held in the slots o of the rods L' by pins q. This shaft O is provided with a hand-wheel, P, by turning which the levers L are moved through the rods K L' to elevate or depress the templet H, and thereby adjust the tension of the hooks and clamps H' I. The clamps I are suspended from the hooks H' with their` clamping-points downward to seize the edges of the leather D', and they are provided with eccentric levers 'm2 for adjusting the gripe of theirjaws or points upon the said leather D'. On loosening the nuts n2 the telnplet H, levers L, cranks O2, and their connecting-bars can be moved parallel with the bar A2 for the adjustment of the said templet H over the last l).

Q represents the holding or pressing` screwbolt, provided with hand-wheel Q', that passes down through plate r, barAZ, and guide-plate s, and freely through the templet H, with its points resting on the last D, for the purpose of holding the latter rmly down in its seat during the process of lasting a boot or shoe, and said bolt Q may be screwed up or down in the plates r s, that are made to grasp the bar A2 between them by the thumb-screws s'; and by loosening said screws s' said bolt Q may be moved laterally, that its pressure may be applied to any part of the bottom of the last D that may be desired.

In the drawings two sheaves, g', are shown journaled in a socket in the cross-bar G', which sheaves are for a cord to run over when the machine is operated by power, in which case the cord will be made fast to a slide that may be moved to and fro to open and close the curved levers G.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In a lasting-machine constructed substantially as herein shown and described, the com bination of adjustable heel-seat and standard C C', adjustable toe-seat and standard E E', adjustable clamping-lever standard F, adjustable templet H, adjustable hooks and clamps H' I, adjustable levers L, with their attachments, and adjustable pressing screw-bolt Q, arranged as set forth.

2. The combination, with the toe-seat Il, standard E', and bar B, of the spindles d (Z2, nut d', socket d3, and screw (1", as and for the purpose described.

3. The combination, with the levers G, ofa socketed standard, F, slotted bar B', spindle and nut ff', screwj', the spindle F2, having lug F3, and the pinsf* g, as and for the purpose described.

4. In a lasting-machine, the hooks H', th readed at one end and provided with nuts 7L', in combination with the templet H, as and for the purpose set forth.

5. In a lasting-machine, as a means for longitudinally and vertically adjusting the templet H and hooks and clamps H' I, the combination, with the slotted bar A2, of the rods K, levers L, adjustable standards M, rods L', cranks O", shat't O, and their respective pivots and nuts, substantially as herein shown and described.

6. In a lasting-machine, the combination, with the bolt Q, of the plate 1', bar A2, guideplate s, templet H, and screws s', as and for the purpose speciiied. y

The above specification ot my improvement in boot and shoe lasting machines signed by me this 19th day of July, 1881.

SOLOMON ll. ELLITIIORI.
