HEELING, NAILING, AND FINISHING JACK.

SPECIFICATION forming part of Letters Patent No. 396,076, dated January 15, 1889.

Application filed June 25, 1888. Serial No. 278,166. (No model.)

To aZZ whom, it may concern.-

Be it known that I. GEORGE DOR'WART, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Heeling, Nailing, and Finishing Jacks, of which the following is a specification.

My invention has relation to jacks for nailing, heeling, and finishing boots or shoes of the form shown, described, and claimed in Letters Patent of the United States granted to me on the 25th day of October, 1887, No. 372,132; and it has for its object to cheapen and improve the construction of the jack and make it more durable and etficient, whereby the operations of nailing, heeling, and finishing a boot or shoe are still further expedited.

My invention accordingly consists of the combinations, constructions, and arrangements of parts, as hereinafter described in the specification and pointed out in the claims, reference being had particularly to a toe-rest head or supporting-block having a springsupport in a standard rigidly secured to the rotating plate, to which is also correspondingly-secured the heel-post for the last, where by both the standards or supports for the heel and for the toe of the last are rigidly secured to the rotating plate and the toe-rest, and its supportingblock has a direct up-and-down' vertical movement instead of a radial movement, an d a firmer foundation is provided for resisting the shocks incident to hammering or nailing than is provided by the construction shown in my aforesaid patent, and to so pivoting or hinging the jack that it can be firmly or rigidly held in any angular position.

Reference being had to the accompanying drawings, Figure 1 is a sectional elevation of a jack, showing my improvements. Fig. 2 is a plan of the head or supporting block for the toe-rest. Fig. 3 is a horizontal section, partly in plan, of the toe-rest supporting-block stem and the standard therefor detached from the rotating plate and showing a preferable construction in cross-section of the standard and Fig. 4 is a vertical section drawn to an enlarged scale through the hinged or pivotal connection for the jack, showing more plainly the spring-actuated locking-bar for holding the jack in its normal position and the clutch mechanism for holding it in an angular position. Fig. 5 isan elevation of same, looking in direction of arrow at, Fig. 4. Figs. 6 and 7 are elevations showing the inner faces or sides of the clamping-plates to which the jack is hinged or pivoted; and Fig. 8 is an elevation, partly sectional, showing the lug on the jack, which is inserted between and pivoted to the clamping-plates, the same being shown detached from the jack and the lockin g-bartherefor indicated in section.

A represents a bench, box, column, or other support for the jack, having a treadle, B, provided with an upright rod or bar, I), passing upwardly through an opening, a, in the top a of bench or support A, in a manner similar to that shown and described in my aforesaid patent, or otherwise, asdesired.

O 0 represent, respectively, the lower and upper circular plates of the jack proper, which are preferably swiveled together in the following described economical way: The plate 0 has a central opening, 0, surrounding which, on its under side, is a shoulderor annular recess, 0', for the reception of an edge flange, cl, of a tubular sleeve, D, in opening 0, as shown. The exterior of the upper end of sleeve D is threaded, as shown at cl, to screw into a threaded opening, 0 in the top plate, 0, and thus loosely secure or swivel said plates together to admit of rotating the top plate, 0, on the lower plate, (7.

The :t'oregoing-described swivel-connection is such that no part of the sleeve D depends below the bottom of the lower plate, 0, and hence the latter can be placed upon a bench or other support without necessitating a specially-formed recess or enlargement at the top of the opening a in said bench or support, as

is required with the form or swivel shown and described in my aforesaid patent. Furthermore, the said form of swivel herein illustrated firmly holds said plates together and admits of easy removal of the top plate, 0', from the lower plate, 0, and corresponding replacement for repairs or other purposes.

2 seearte post is provided with an adjustable top pin, 6, for insertion into the top of the heel part of the last, and with a set-screw, c, for said pin,as set forth in nrva'tforesaid patent. The toe-rest F is adjustable in a head or suptnn'ting block, t, which may be of any suitable construction; but I prefer to made it as hereinafter to be described. This headblock (t has a stem, g, which is inserted in the bore 71 of a tubular standard, ll, in which is a spiral or other spring, 71, upon which said stem rests, so as to have a spring bearing in standard or column ll. The spring ll has an upward action to normally keep the ln' ad-block G and toe-rest l elevated or to move them upwardly,

The standard It is rigidly secured to or east on the plate and is n'ovided with vertieally-arranged slots 71 through which passes a cross-bar or studs, g, secured to the head or supporting-l)lock stem g. The ends of bar or studs 9' are preferably provided with rollers g which project: laterally b(, vond the standard II, as shown more plainly in laig. 3. The studs or bar g and 'the upper end of slots 7: limit the upward movenn'ent of stem 5 and consequently of the head (i and toerest F. The upper side of the head-bl wk (l is provided with aseries of. transverse grooves or recesses, G, of the corrugated communicating form shown in Fig. 2, or they may otherwise be ('(mtigured and arranged, as desired, to eontorm to the shank end fol? the toe-rest F, so that said end f may be inserted into any one ol? the recesses G to admit olf adjustably attaching and detaching the toerest- F to the head G, as desired.

To give the proper inclination to the toeresl ll as it is adjusted in the head (l, the lat: ter isol' a curved tin-segmental form, as shown in Fig. l, and the recesses Gtherein conl'ln'm to the ctmliguration ol' the block.

llpon one side of standard It is :rlug, 71", having a stop'piece or end, 71 ,and to this lug 71 is pivoted a lever, K, the upper part of which is bifurcated to embrace the standard 11, so as to admit oi each leg or end ot. the bil'ureation impinging against oneol' the rollers on studs or bar 5 T0 the lower end, 7a, of lever K is pivoted a block, I, having, 1)l.'6l'. l;ll.)l a concave or recessed under side, 1, into which enters the top of treadle-bar (1, as shown in l ig. l, to be in line with said block I and lever 11 when in their normal positions, so that when the rod 1) is elevated by depressing the treadle ll the block I is C-(ill'GSPOlllllllg'ly moved to oscillate lever K in the direction of arrow y, whereupon. its lever ends moving against the stud or bar rollers on the head-stem g, dc press the latter and. the toe-rest. F, as indicated by dotted lines, Fig. l. As soon as the pressure on the t-readle is rennived, the reaction of spring 7t returns the lever ll, head G, and toe-rest F to their normal positions. The plate (J is provided at its periphery, on one i side of the same, with a lug or bracket, 9)), terminating in a disk-shaped end, on, having a central aperture, m a peripheral recess or slot, in, and on one or both sides a lug, /11 located, preferably, between the opening m and the taco ol' the disk. This disk is insorted between two upright plates or leaves, N N, cast or secured to a base-plate, n, so that they will not be connected one with the other. 'lhebase-plate a is suitably and firmly fastened to the top of the bench or support A, as indicated.

'.l"heplatcNhas a central round aperture, )1, and. the plate N" an angularcentral aperture, nfleomm unicating with the l all? or of a tul n1 lar projectiml, n, on the inner side of said plate, which tubular projection '11" forms a bearing for the end or disk in ol plate as more plainly shown in Fig. 4'.

Upon the inner sides ol the plates N N are preljerabl v vertically-loeated. lugs 11? 01", and at: or near the bottom olf plate N is an opening, n, registering with theslot m in the periphery ol? disk end '11:. into or through tjheopening a and slot at" passes a bar, 1, having an aetuatirig-spring, p, an end bearing-,pi in the base-plate n, and a handle or tlnnnb-piece, p". The action of spring p is to normally move the harp into the slot in to lock thediskend m and plate and consequently the plate and lixtures thereon, in their normal position, or as shown in Fig. '1.

Through the central openings, n 11*, olf plates N N passes a bolt, 1, having an angle lar part, "r, correspoinling to the angular opening n' in plate X, and being provided with a thumb-nut, r recessed, as shown at r", in its rear side for the reception ot a spiral spring, r, for prevent ingthe thumb-nut-working loose by the vibrations incident to pegging or linishing ot' the boot or shoe, and also to exert a pressure between the nut and the plate N l'or clamping purposes, about to be described.

From the foregoing it will be noted that the plate or its disk end m is pivoted upon the tubular bearing n of plate N. ("onsequently when the thumb-nut r is unscrewed or loosened and the bar withdrawn from the d isk-end slot on the jack can be raised to any angularposition desired until itslimitot' motion is reached, which happens when thelugs 1/1. on the disk end n! abut against the vertical lugs a on the inner sides of the plates N N", which lugs llHI'tl UI'O are stops for limiting the movement of thejack on its pivotal or hinged connection.

The jack is lirmly locked in the angular position desired by turning the thumb-nut r until the plates N l\" clamp or bind against the sides ol the disk end m, said clamping by the turning of tho thumb-nut being as sisted by the pressure of the spring r.

It" desired, a washer, .9, may be inserted between plate L\' and the not w to avoid wear of said plate.

A jack constructed as above described can be applied to any bench or support, and is easily and expeditiously changed from its normal to an angular position, and when clamped in the last-named position it is firmly held so that the boot or shoe may be hammered or otherwise operated upon without jarring or straining the parts of the jack or loosening the effectiveness of its clamping engagement. \Vhen the jack is raised to an angular position, the normal position of lever K is maintained by the tail or stop piece If of lug 71. which prevents a movement of the lever K away from the standard H, and as the block Z is pivoted to the lever K it always swings into its .normal position when the jack is lowered.

If desired, guides 6 may be formed on the stem g of head G, which guides enter vertical ways or slots l in the standard II, as indicated in Fig. 3, to give a firmer bearing to the stem 9 in the standard and avoid strain on the studs or bar y when the spring 7L2 acts to move the toe-rest F into contact with the last to clamp it upon the post-pin e. As the clamping of the last to the post-pin e is effected by a direct upward or vertical move ment of the toe-rest F, a corresponding movement in a reverse direction instantly lowers the toe-rest from the last to at once release the latter, whereas in my aforesaid patent in releasing the last .it is further clamped to the heel-post by the radial movement of the toerest against the last before leaving the same.
