Zo all whom it may concern: Be it known that I, GILBERT HAWKES, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Lasting Boots and Shoes, of which the following is a specification.- 1 My invention consists in devices whereb the upper of a boot or shoe being placed upon a last lastedi. 0., drawn by suitable mech: anism into its proper position and there made s more or ihstened, so as to be ready to receive .the outer sole.

I will now proceed to deseribemy improvements as embodied in a machine and illustrated in the following drawings, in which liigUIT-B 1 represents a plan view of my machine, the gripping atintchment having-"been" Fig. 1 represents "the under side 2 represents a plan view similar to- Fig. 1, except that one ot'the slides is removed, witlr the parts immediately connected with it, to Show the parts beneath. Fig. 3 is a vertical section on the liner a: of Fig. 1. Fig. 4 is a vertical section on the line 1, y of Fig. 1. Fig. 5 is a plan view of the gripping device. Fig. 6 is a Longitudinal vertical section on the line z z of Fig Fig. 7 is a transverse vertical section on the line in w of Fig. Fig. 8 is a bottom: view of the auxiliary gripping device.

The machine, as a whole, includes, first, mechanism forcurrying thelast; sec0nd,mechanism lbrstretching or drawing the upper vertically above the edge of the last; third, mechanism for stretching or forcing the upper latcrnlly over and beyond the edge of the last, and, fourth, mechanism for temporarily secur the stretched upper in position, where it may be permanently secured by nails, pegs, cement, or other practicable means..

My machine is constructed with a rectangular frame, A, of suitable material, consisting of four uprights at the corners and stayed by proper cross-pieces, A, at the bottom, top, and middle. Within this frame, resting upon the stay-s placed in the middle by suitable sup-poi. s, is a second i'raine, B. Thisis'partially covered, but so as to leave an open space pieces. Resting upon this second frame by suitable supports,'B', securely fastened to'it, is a frame, 0, of the shape of the sole of a boot or shoe, but somewhat larger. The upper having been. put onto the last, the latter is' passed into the machine, through and beyond the frame or yoke G, to a support, D, on which thelast is supported while the lasting is performed. This support is set in'a well in'the middle of the second frame, B, and rests upon shoulders or projections from the frame B, (see Fig. 4,) by which 'it is supported, and it is capable of vertical motion within 1118* well.

For the more effectual verticalfirawing or stretching of the upper beyond the last, I ar: range a device co-operativewith and auxiliary *tUf'UlJEUtiIBI devices 'irrtheinaehiiie'y'l'aterde scribed. This device, which is so constructed as to be readily detached from the machine, and which is also made capable of being brought up to or removed from its place of working while stil' ,emaining onv the machine, is now thrown over upon the hinge, by which it is connected with tlieinachine, and thus brought into place over the last. X

The mechanism shown in detailiat Figs. 5, 6, 7, and 8 consists-of a series of pinchers arranged aronnd the edge and on the lowersurface of a frame, B, of the shape shown 'in the, drawings. The inner jaw, i, of the several pinchers is attached to an elongated. piece of metal or bar, is, attached to screw-rods 0" passing through the under side of the frame B, and these several jaws turnfreely on pivots, which connect them .with this elongated piece of metal.- .The other or outside jaw, i, of each pincher is connected with a rod, t, whichrims throughto the upper side of the frame, and can be drawn down when" desired, as will be explained. Upon the under side of" each of these rods is a nut, u, and around each rod, inside oi' the frame, is a coiled spring, t,which is compressed by means of a head fastened to the rod. The object ofthese heads and nuts 9 5 is to give greater or less rigidity to the springs t, as required. There is also-a lug. or ear, 3; on the inner ends of the outer jaws oil the several pinchers, to which .is attached ai'spring,

for the reception of the heel, toe, and side p, the upper end of which formsa rod,p, runoo of the upper is regulated at pleasure, while each pincher still remains capable of being moves the plate above referredto, is so turned ments, except the sole-shaped plate.

and toe, respectively, the portions of the upper ning through a metal plate, E, placed inside of the frame B. On the end of these springrods, which is outside of this plate E, is a nut, as shown. By means of the springs p t and rods 1;" t the grip of each pincher on its part swung in around its pivoted'connection with the elongated piece of metal or bar k.

Through the elongated piece of metal or bar k, above mentioned, and near each of its extremities, runs a rod, 1-, connected at one end to a second-piece of metal, j, of the shape of the sole of a shoe,'called a downhold. The rod r'is screw-threaded, and the interior of the elongated piece screw-threaded to match. Theserods pass through apertures in the plate E, screw-threaded to correspond with them, and extend to and through the upper side of the plate E, above referred to, and at this extremityof these rods is a milled head, r. Through a screwthreaded aperture in the center of this plate E passes a screw, F, the lower end of which has a socket-bearing in the frame E. By means of this screw. the plate E may be raised or lowered in the frame B. When it is lowered, the rod 1), fastened to the inner part of the outer jawai, 'of each pincher, moves down, and the rod t, attached to the outer part, at, of the outer jaw, t', of each pincher, moves up, andthe pinchers thus open. When the plate E is lifted, the inner rods, p, are pulled up, and the jaws i, to which they are attached, close. The operation of this part of my invention is as follows: The lowermost plate, '9', above described as of the shape of the sole of a shoe, rests upon the bottom of the shoe to be lasted, and it is of such size as to be within the line of the edge of the upper after the latter is drawn over, and thus it does not interfere with the-i inward movement of the lasting-jaws. .The pincher's i z" engage with the upper of the shoe to be lasted and pull it up. This is done in the following manner: The screw F, which as to push down the. plate E. The pinchers thus open, and being so placed as to come in contact with the upper of the shoe to be lasted, they engage with it. The screw F is then turned 'the other way, the plate -E rises with the several rods attached to one jaw, i, of the pinchers above described, and the pinchers close upon the upper and hold it firmly. Next the two rods. 'r are turned, and as they are turned they raise the bar k, with its attach; I

The next operation. is the gathering in and lateralstretching of the upper over'the edges of the last, and I accomplish this by arranging for the heel and toe a pair of geared quadrants, a-a, which, opening from each other, bring together in proper shape over the heel which in lasting are to be gathered in, and by arranging for the sides of the boot or shoe to be lasted sliding pieces h h-one on each sidc "being lasted.

, heel.

which, when pushed in toward each other by proper mechanism, force in the portions of the sides of the upper which are to be lapped over the bottom of the boot or shoe which is These heel and toe pieces are placed on slides h, which pass over and upon the second frame, B, through spaces left-for the purpose, the upper surface of the heel and toe pieces moving upon the under surface of the frame or yoke G and over the inner extremities of the slide it, and passing beyond the ends of the last. These heel and toe pieces are quadrants in form, except that a small portion of the angle of the quadrant is cut rants the proper form at this part to gather in and hold the upper in lasting the toe and In the drawings these, quadrants are shown so cut away as to be curved concentrically with the adjacent portions of the frame 0. The outer side or periphery of these pieces is geared and adapted to engage with other gearing, whereby inoperation they are turned away from each other at their periphery. At the end of their turning the two extremities or inner curved portions of these quadrantal pieces form together an arc something less than a semicircle.

Grooves are cut in the slides h upon which the quadrantal pieces a turn, and these engage with the curvilinear projection or rib on the under side of the quadrantal pieces near the segmental ends. As thus constructed and arranged,

the quadrantal pieces are prevented from being moved. vertically or laterally from their proper position, and are confined to the; circular motion above described. On the sides,

(See Fig. 1.) The slides h h, upon which these pieces turn, have a rec1pro- Lcating motion toward and away from the last.

also working beneath the sole-shaped frame 0, are side lasting'pieces, h, which also pass over the frame B and beneath the yoke C.

These side slides, h h, when'moved forward, push in the sides of the upper over the last.

wit, the heel-quadra nts, the toe-quadrants,

The plane of the .four movable piecesto,

and the two side pieces by which the drawing in of the leather is in part accomplishedis just ovexathe last. These pieces may be re placed by larger or smaller ones, so as to be adaptedto the lasting of boots and shoes of diflerent sizes.

The several parts j ust described are adapted by suitable m'echanism,which willbe'descri bed belcw, to move in the following order: The pieces h h, to which the quadrants are attached, move forward toward each other until the quadrants come in contact with the upper. \Vhen this has been done, the quadrants begin to move and gather in the upper at the heel and toe simultaneously with the still further forward motion of the sliding pieces h hthat is, they (the quadrants) are gathering in the upper and moving forward at the same tiu1e and by this motion of turning on a center which is always moving forward over the last in the direction of its lougcstaxis, and which,

, of one also, is always a point in the curved face by which the plaiting or lasting is done, I am enabled to do it very successfully. The advantage of having this center of turning always in the curved face by which the lasting is done is that no part of either quadrant passes by the otheror, in other words, that no motion lade over another, as in shears, is permitted. Such a shears motion is objectionable, in that it tends to catch or cut the upper between two transverselymoving plates, and thereby mar it, or otherwise injure the perfection of the folding or plaiting- Another advantage is that no gap is left between two blades or plates moving toward each other in the same plane, within which the upper may be caught; but all points of the edges of the two quadrants move in circular paths, and,

no point has a motion toward another between which motions the upper may be caught, but every point moves in such direction toward the center of the last and of its too or heel as is required to produce at that pointthe direction and character of strain upon the leather that characterizes the most perfect hand-lastmg.

My construction differs from those formerly used in this -respect, among others-Via, that thetwo plates which form my heel or toe last ing device are not superposed one upon the other, like. the blades of scissors or shears-and their pivot is substantially in the line of their curved operating-faces.

The operation of plaiting or gathering in-of the 1 9.61 at the heel-and toe and at the sides of the last by means of my appliances secures smoothness and trucness of position of the upper relatively to the last, which is very desirable. The upper having been properly drawn up and the gathering in completed, the jack V, carrying the support D, is now moved up by mechanism. hereinafter described, and

.the turned edge of the upper pressed against the under side of the slides and quadrants, thus holding the upper place. The motion of the rod F is then reversed, and the plate E, with its attachments, descends, causing the pinchersii to open and release their hold oftheupper. The gripping attachmentcanthen be turned back by means of a hinge connecting it with the frame of the machine. After the upper has been drawn in, as explained, it is 'tobc secured to the inner sole in any proper way. The process of iasting is' thus B0111- varions parts which contribute to perform the I various operations above described are as fol.-

lows: There is at the bottom of the niachinea screw, T, turned by a wheel, S, to which one extremity of the scre'wis attached. The other extremity fits into a shalt or jack, V, with cairrshaped sides, of the form shown in the drawings. "When the wheel S is revolved one way, the shalt V rises by means oi' the screw -l7, and when it is turned the other way it desuends.

loses 3 Aroundlhc shaft V, and so placed as to be actuated by its canrsides, are pieces of metal w, hinged at the bottom to the frame of the machine, andadapted' to be pushed back by these cam-sides when the shaft V rises, Two of these pieces w,placed on opposite sides,have for the face which impinges upon the camsides 'asniall roller. 1. These two act upon levers Q, the ends of which, impinging upon the pieces 20, just mentioned, are supplied with small rollers3. As the shaft rises the cam-sided shaft pushes back the hinged pieces,

hich in turn depress the ends of the levei-s'q next to them, and thus the other end is pushed forward against the slides 71, whose oilice is to push'in the sides of the upper of the shoe to be lasted. The other two pieces placed opposite to each other are similarly constructed, and operate first, as above stated, against similar levers, g, which cause to move forward the parts designed to gather in the heel and toe ot' the shoe to be lasted; but these last levers are also provided with belts, which are fastened at one end to the cam-.sidedshaft or I gears-0 are others-2, which engage with-midturn the quadrants a.

In order to make the parts which the'heel and toe of the upper act first and the parts which gather in the sides of the upperact afterward, the cam-sides should not all be 'on. the same horizontal plane; but those two on opposite sides of the shaft or jack V for opcrating the heel and toe "pieces should be on the same level or act at the same time, and those two for operating the side pieces or slides on a lower level, and. thus act together a little later. Only two of these cam-sides are illus gather in trated, (see Fig. 3;) but the other two are the same in form and should be zit-right angles in position to the twoshown, and on a slightlyvdifferent level, as will be understood by those skilled in the art of constructing-lasting-nun chines, When the cam-shaped shaft reaches the supportD on which the'last rests, it raises the support, the last and the shoe upon the last pressing the turned edge of the upper against the slide and quadrants, thus holding it firmly'in place. The upper is then released from the grip of the pinchers and the auxiliary device is thrown back on its hinge, leaving the edge of the upper exposed, so that .it may be permanently secured by nails, pegs, cement, or other practicable means. upward travel of the cam-shaft V, and conse- The extent of the I go quently the amount of pressure to secure the turned edge of the upper in place,n1ay be regulated'at will by varying the distance to which the screw T is driven into the cam-shaft.
