LASTING AND PEGGINQ'JACK.

SPECIFICATION forming part of Letters Patent No. 268,019, dated November-28, 1882-.

' Application ined Apn'l 14, lese. is model.)

.'l'o all Iwhom it ma y concern:

Be it known that I, Ganan W. H oDGDoN, of Boston, iu the State ot' Massachusetts, have invented Improvements iu Boot and Shoe Lasting and Begging Jacks, of which the following is a speeiticatiou.

This invention relates to thejacks iu which the last is heid while the upper is'being stretched thereon and secured to the'insole; and the. invention consists in the construction and combination of the various devices enibodied therein, as will be hereinafter, in connection with the accompanying drawings, fully described, and specifically defined in the appended claims.

Figure 1 is a side elevation ofajhck which embodies my invention, the base being-broken- Fig. 2 is a seetional elevation oi' said jack, taken as viewedfroni the right in Fig. 1, the sectional'parts being taken as on line W, Fig. l. Fig. 3 is a sectional elevation taken as on line x, Fig.1, and as viewed from the right therein. Fig. 4 is a detached sectional elevation, showing one of the clamping-blocks and the upper portion of its supportiiig-standard in elevation and the connecting-coupling in longitudinal sec- Fig. 5 is an elevation, showing one of' the clamping-block standards jointed, and with a moditieation in the rotatingand elevating devices. Fig. 6 shows a left-hand last iu section, astaken through the shank, or on line W, Fig. 1, and the clamping-blocks in elevation. Fig. 7 isa view like Fig. G, except that the last shown is a right instead of a leftl Fig. Sis a detached elevation taken as viewed from the right in Fig. l, and showing the lower portion ofthe machine, which is omitted in said Fig. 1.

In said views, A represents the base of the machine, by which it may be secured to a bench or other suitable support. Said base is surmounted by part a, in which is fitted to be revolved the hand-wheel b, whose hub or ceuter is threaded to serve as the nut of screw C, which latter is secured in or formed as an integral part of bed-plate 1i, which carries the last-supportingdevices to be described, and 'b'y rotating said wheel b its coacting screw U, the bed B, and its attached parts may be raised Under the front end of the basent' standard o r lowered at will. The clamp-holding rails c c are attheir ends united by cross-bars ce, and are connected with andsupported by the end braces, g g, and the lateral braces f f f f, all which braces rise from part a of the base 5 5 A, as shown in Figs. 1, 2, and S. To prevent rotation of bed B, when being raised or lowered, by the action otwheel b, the guide-pins h I: are secured in part a. and extend loosely' through holes in B, and so hold the same from 6orotat-ion without impediug its vertical movements.. The last D, at its heel, is supported upon standard i, the stem of which enters a hole in the top of the last, as shown in Figs. 1, 2. Said standard is pivoted at l in ears j ot' bed B, and it is rocked forward by cam-lever k, pvoted at Vin a rearward projection -ot said standard. A spriug,^-m, seated between bod B and ai'ront projection ot' the standard, serves to rockthe same backward when cam lever k is released. The toe ofthe last is supported by-standard n, which is pivotd at' p to 'saddle t, which is dovetailed to and is adjustable upon the way o of bed B. (See Fig. 3.)

u is arranged an adj usting-screw, y, threaded in saddle t, and provided with a hand-wheel,

s, by which toactuate il'. By means ofthe sliding saddle t standard 1i maybe adjusted at the required distance from heel-standard i to suit all sizes df lasts; and by means of screw' y standard n .may be inclined at any desired angle, `while cam-lever k serves to seat the toe of the shoe firmly in standard u. The clanxping-block standards d are formed with a foot, 2, which [its to the rounded head of rails c, and so as to be moved' lineally thereon, and also to be rocked outwardly and inwardlyto the requisite extent towengage aud be disengaged from the shoe. 'The upper portion of said 9o standards is formed with escrow-thread, upon which is titted the sleeve, 3, so as to be vertically adjusted upon the standard. In the upper end of said sleeves is fitted to revolve freely t-he stem 4 ot' bracket5, in which is pivoted the clamp-block 6, to which is secured the capplate 7. Sa id clam pin gstandards' are arrau ged in pairs,(in the desired nuniber,)aud each pair is compressed upon the shoe by .the rod 8,

provided with a-1ever-nut,9,threaded thereon 10o at one end, and with a caxn-lever, 10, pivoted at the other extremity. By actuating nut 9s the blocks 6 may be adj usted 'at the desired disconnected from said rails at the end thereof, dist nceapart for thc shoe t belastedgvhen but can be moved thereon to a y-desired point, by' tuatingvcam-lever 10 th vpressure is ap. and can be vibrated toward orfroxn last D,
