To. all whom it may concern:

Be it known that we, SHERMAN W. LADD and Eowzuiu At Srrooixs; both of Beverly, county of Essex, Commonwealth of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following, read in connection with the accom anying drawings is a specification.

T is invention re ates particularly to lastin machines of the type known as the 5 han metho lasting machine. One -form of this type of machine is illustrated in Letters Patent of theUnited States No. 584,744, dated June 15, 1897, and No. 597,321, dated January 11, 1898, to which reference may be had for a description of the general features of the machine. The machines illustrated in the above-mentionml patents are equipped with appliances for ad apting them especially for lasting Goodyear or welt shoes, whereas the present invention is shown as embodied in, a machine for lasting McKay shoes and certain parts 'of a welt lasting machine are omitted from this machine.

In the drawings, Figure 1 is a side eleva; tion of a lasting machine embodying our invention. Fig. 2 is a side elevation on an enlarged scale showing the parts of the ma chine with which our present; improvements are connected. Fig. 3 is a plan view of the parts shown in F ig. 2 with the eccentric disk 44 shown in section. Fig. 4 is a view similar to Fig 3, showing the parts ina different position; Fig. 5 is a front elevation of the arts shown in Fig. 2 and also of the driver ar. Figs. 6 and 7 show details of the new mechanism.

' The lasting machine herein shown is provided with a thin edge-rest 10 secured to the frame of the machlne and adapted to be used for guiding the shoe while the shank of the shoe is being lasted.

12 indicates an ed e-rest arranged to be moved forwardl an backwardly with re-- lation to the 12-has a. thick acting face and is adapted to be used while the toe'and the heel of a shoe are being lasted and is intended to be moved baekwardly out. of operative position while the shank of a shoe is being lasted. It is necessary to move the thick edge-rest Bpeciflcation of Letters Patent.

12 backwardly for lasting the shank because the shape of the shoe is such as to make it im racticable for a thick edge-rest to be used For guiding. the shank of a shoe The edge-rest 12 is, arranged to slide on a guiding rib 13. which depends from the frame B of the machine, and the rest is provided with a finger'epiece 4 by which the operator may conveniently move it forwardly and backwardl'y.

The edge-rests above described are'fi'llly disclosed in United States Let-tors Patent No. 562,119, granted onJune 16, 1896, and need not be further described herein.

The lasting machine is provided with mechanism for supplying fastenings to' be inserted for holding the successively lasted portions of upper in place. -This mechanism will preferably be the same iii-construction and operation as that shown in Letters Patent No. 584,744, before mentioned, except as hereinafter explained.

The mechanism forsupplying fastenings as herein shown comprises among its parts a movable guide, shown as a raceway section or block 14, provided with a plurality of channels 16 and 18, for holding difl'erent sizes of tacks. The block 14 is pivoted at 20 th the machine frame and.is arranged to he moved for placing either of the channels 16 or 18 opposite the -discharge opening 22 in the fixed plate 23. The tacks are acted upon by a tack separating mechanism located below the fixed plate 23 which allows them to escape one by one through the opening 22 into a tack carrying block. The tack separating mechanisln and tack carrying block form no part 0 the present invention and are therefore not shown or described.

It is desirable to use tacks of one size when the machine is operat' on those parts of the shoe where the thln edge-rest 10 is employed and tacks of a dilferent size when the machine is operating-on those parts of a. shoe .where the thick edge is employed. structed for lasting McKay shoes the shiftin of the taeksuppl' I mechanism-for cahsin 3%1lfifcnt sizes of it to clip 1 tacks as been leg/ii theworkmamand as it constituted a independent adjustment,

'-rest 12 eretofore in machines confor all the di he, in ractice, omitted. to make the chin e, and, t erefore used the same size of tac s erent parts of the shoe to the detriment of the work. It is, however, indispensable to the roper use of the machine that the wor an change the position of the thick edge-rest 12 in going around the shoe and such changes in position are made at the time when the size of 10 tacks should also be changed. Thus the thick edge-rest 12 must be in its forward, operative Position when the heel and toe rtions o the shoe are beinghlasted teatorda wide bearing against w ich the work ma be firmly held, and in the lasting of the bee and toe portionsof the shoe it is desir-able, in what is known as McKay shoes, for which class of .work this invention is especially intended, to use long tacks to compensate for the increased thickness of the stock caused by the 'fiange of the counter and the folds of the upper at the heel, and by the folds of the upper at the toe. On t a other hand, imlastin the shank and ball portion of the upper, t e thin edge-rest 10 is used, and the rest 12 must be moved back into ino erative position. In lasting the shank on ball of McKay shoes, the upger 54, which per stock to be secured is less bulky than at the toe and heel and, therefore, it is preferable to use shorter tacks than are used at the heel and too. In this embodiment of our invention, therefore, we have connected the edge-rest and the tack raceway section 14 so t mt when the edge-rest is changed the raceway is also simultaneously shifted and caused to supply a different size of tacks. To this and mechanism is provided as follows :-A bracket 24 is secured, by bolt 26, to the machine frame B. In said bracket is journaled the shaft 28, in whichthe shank or radius bar 31 of a toothed se meat 30 is clam d by a screw 32, the sha t 28 being for t is purpose slotted at the, point 34, see Fig; 7. A plate 36 is fixed to the edge-rest 12 y screws 38 and has toothed formations 40 in mesh with the toothed formations on the segment 30 for turnin the segment and the shaft 28. A disk 4415 mounted eccentrically on shaft 28 to which it is secured and-it is provided in its lower side with a cam groove 46, formed as the are of a circle whic is concentric with the disk 44. A conncctin -rod 48, extending between the disk 44 am the tack supplying mechanism, is composed of sections a, c. The scctiona has on one end a. ball which is sockctcd in the raceway section 14, and the other end is in screwthrcadcd engagement with the section a, which is slotted at, its rear end, as at 50, for loosol embracin the shaft 28. Said section is provided with a hollow stud 52, wherein 15 arranged a spring-actuated planhas a conical end for entering cavities 56, 58 in disk 44 at the upper side of the groove 46 and frictionally holding the parts atone or the other limit of their movement. It will now be understood that a movement of the edge-rest, 12 to theforward or working position turns the segment 30 and the eccentric 44'for placing the racewa section 14 with channe 16 in comm'uni cation with the discharge opening 22 in the plate 23 so that one size or kind of tacks will be supplied, and movement o f said rest 12 to its retractedor xion-wo'rkin sition reversely turns said segment an isk for placing channel 18in communication with said 0 ening 22 for causi a difierent size or kin of tacks to be supp ied.

It will be understood that-the member 12, instead of being arranged to slide on the. member 10 as herein shown, could bearranged to swing about a pivot, the only essential being that the edge-rest shall have a connection with the tack supplying mechanism such that nism will be caused to supp y .one; size or kind of tacks when the thick edge-rest 12 occupies its operative osition and said mechanism will because to suplplya difien ent size or kind of tacks when t e thin edgerest is operative and the thick-ed e-rest occupies its inoperative position. -T is invem tion is not, therefore, limited to the construction herein shown specifically;

It is an important feature of the Invention that the adjustment of the fastening sup lying kin of fastenings 'or another determines which of the edge-rests shall be operative for uidin the work;

l ile -t e invention is herein shown as embodied in a lasting machine in which loose tucks are driven for securing. the upper, it will be obvious that the "invention may be employed in other machines and that it is not essentialto the invention what kind of fastening material is handled by the machine. 1
