LASTI NG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 251,205, dated December 20, 18 81.

Application filed September 24, 1879.

To all whom "Lt may concern Be it known that I, WM. E. FISCHER, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to lasting-machines for lasting boots and shoes.

In the machine herein described the last is mounted on a support which is so sustained as to exert an upward pressure upon the last, the normal condition of the last-support being such as to elevate the bottom of the last above the line of action of the heel and toe lasting devices, the level of the last-bottom being determined by a stop. The side-lasting devices, herein shown as plates adapted to operate against the upper along the sides of the last and lay the edges of the upper over on the face of the inner sole, and also the india-rubber rubbing-pieces attached to the said side-lasting devices, are as in other earlier machines. The heel and toe lasting devices are composed of independent radially-moving fingers, each be- 'ing so supported as to be independently actuated or moved horizontally over the heel and toe ends of the last or inner sole. The sidelasting devices having laid the side edges of the upper over upon the inner sole, the central finger of each set of heel and toe lasting devices is then moved to crowd the upper at the extremity of the heel and toe over upon the inner sole, they acting to sweep the wrinkles at said extremities laterally with relation to a line drawn along the center of the lasts bottom from heel to toe, throwing all the wrinkles about the curved parts of the said toe and heel into the space between the said central fingers and the side-lastin g devices nearest them, after which the finger-plates are automatically thrown forward, acting upon the wrinkled and full portions of the upper between the central fingers and side-lastin g devices and crowding the said portions over upon the face of the inner sole. The finger-plates, moving radially into the space between the central fingers and side-lastin g devices, prevent the upper being folded or caught between the edges of the central fingers and finger-plates each side of them. Just within the toe-lasting fingers,

and having its acting portion within the are occupied by the front ends of the toe-lasting fingers when drawn back, is a toe-piece supported on a spring, it being adapted to come against the upper at the toe of the last when thelatter, with the upper andinner sole thereon,

and the toe-lasting devices are being changed vertically as to their positions with relation to each other, the inner sole being then acted upon more or less near the ends of the last by the downholds. The said downholds are shown as adj ustably connected with an arm, so that, resting in contact with the inner sole at two points between its toe and heel, they will position the heel and toe with relation to each other and prevent the "last tipping longitudinally as the relative vertical position of the side-lasting devices and last-bottom are automatically changed with relation to each other, in order that the side-lastin g devices, when subsequently automatically moved forward during the further movement of the actuating parts of the machine, shall correctly meet, act upon, and lay the edges of the upper over upon the face of the inner sole. The toe-restan independent device located just back of the toepie'ce-is shown as a concaved or curved metal plate supported by a spring, the latter spring enabling the toe-rest to yield as the relative positions of the last-bottom and side-lasting devices are changed vertically, while the metal plate is also adapted, by reason of its flexibility, to permit a slight-roll of the last laterally, to

enable the side-lasting and toe and heel lastthe edges of the last.

Figure 1 represents, in side elevation, a lasting-machine containing my invention; Fig. 2, a vertical section thereof on the line 00 :10, the bottom of the last and inner sole thereon being above the level of the line of action of the side-lasting devices, and the hold-downs or pressers being in position to come in contact with the inner sole at two points between its ends; Fig. 3, a top view of the machine after the side and heel and toe lasting devices have been closed over upon the inner sole and the hold-downs have been automatically released and moved away from the inner sole. Figs. 4

and 5 are details in two different positions of the lower end of the lever or arm upon which the hold-downs or pressers are mounted, and the actuating devices therefor; Fig. 6, a detail in longitudinal section of the toe-lasting devices, their adjustable carriage, and toe-rest; Fig. 7, a top view of the toe-lasting devices, the central finger only having been moved forward; and Fig. 8 is a top view of the elbow-lever or actuating device for acting upon the arms which carry the toe and heel lasting fingers or fingerplates.

The frame a of the machine is and will be of suitable shape to hold the moving parts.

The side-lasting jaws or devices b (shown as plates) are connected by screws with the removable pieces or blocks 0, the latter being attached to the vibrating arms or side-lastingjaw carriers 01 by screws 0, the said blocks being also provided with elastic rubbing-pieces], such as described in my patent of the United States No. 44,916. These arms d are pivoted onarod,g, are connected bya retracting-spring, h, and are provided at their lower ends with rollers i, adapted to be acted upon by a suitable wedge,j, or other device, to at the proper time cause the jaws to approach each other and the last to act upon the edges of the upper along 1 the sides of the last and force said side edges of the upper over upon the face of the innerv sole, to be there secured by suitable nails, tacks, or pegs.

The jaws may be changed for shoes of different length.

The last is mounted upon a support, 1, (shown as apinjointed to arod,m,in turn pivoted at 2 upon apivoted lever, 72, having adjustably attached to it a weight, 0, the whole constituting a jack or heel-support,) which acts to press upward the bottom of the last and inner sole to a level above the line of action of the side lastin g devices when operating to lay the upper over upon the inner sole.

The position attained by the inner sole above the side-lasting devices is controlled by the stop 19, against which the lever nstrikes in its descent.

The toe and heel lasting devices are each composed of three fingers or plates-viz., central fingers, r, and two radially-moving fingerplates, 8 or s. The central fingers, having inclined side edges, as shown in Fig. 3, to act upon the upper at the extreme toe and heel and sweep the wrinkles laterally from the extremities of the said toe and heel as the ends of the central fingers move the upper over upon the face of the inner sole, are connected with the upper ends of spring-arms t, which in their normal condition operate to retract the said central fingers; and the finger-plates, adapted to be moved radially over the inner sole near the corners of the toe of the shoe, or at the outer inclined edges of the central fingers, to act upon the most wrinkled part of the edge of the upper, or that part of the said edge of the upper between the closed side-lasting devices and the sides of the central fingers, r, are car-- ried at the upper ends of spring or yielding arms a, which when in their normal condition operate to retract the finger-plates. These arms t and u are carried upon horizontally-act justable heel and toe carriages w w, fitted in suitable guideways in frame at. These arms t u are acted upon to close the central fingers, r, and then the finger-plates s or s by means of a cam-plate, a, (see Figs. 6 and 8,) forming partof an elbow-lever, 3, mounted on a rod in an ear, 4, .of the carriage, and provided with rollers 5, to be acted upon by a suitable wedge or device, 6, on a rod, 7, provided with an adjustable shoulder, 8, and a pin, 9, to be acted upon alternately by the treadle or main actuatinglever 10, when it is desired to close the heel and toe jaws upon the upper, the said wedge 6 acting with its opposite inclined sides upon a roller, 14, of an arm, 15, pivoted to the toecarriage w.

The heel-carriage has an elbow-1ever,13,substantially like the one 3, except as'to the roller 5, and the said lever 13 is connected with the arm 15 by means of connecting devices, shown as rods 12, the said rods beingextended through the pin 16 in the elbow-lever 13, and being connectedat their outer ends with a cross-head, 17, having an adjusting device, 18, shown herein as ascrew, to thereby so position the levers 3 and 13 that they will permit the spring-arms of the toe and heel lasting fingers to retract the same more or less to accommodate shoes of different length and curvature, the same adjusting device also affording opportunity for adjustment of the heel and toe carriages w m longitudinally.

The cam-plate a (see Fig. 8) has its edge so shaped that its part 19 first acts upon the arm t and moves the central finger, r, forward its full distance, or substantially so, after which the edges act upon the arms a and move the finger-plates s or s forward radially, as before described, it being remembered that these finger-plates are not moved forward until after the side-lasting devices and the central fingers of the heel and toe lasting devices have been moved forward.

It will be noticed (see Fig. 7) that the inclined edges of the central finger (it having been moved forward from its dotted to its full line position, in which latter position it will lie over upon the toe ofthe shoe or inner sole) and the edges of the finger-plates s or s are substantially in contact before the said fingerplates are moved forward, and consequently the latter, in their forward movement, shove the fullness or crimped and wrinkled parts of the edge of the upper over upon the inner sole, wiping the said wrinkles toward the edge of the upper and preventing the upper from being caught or pinched between the central fingers .and finger-plates; and it is also obvious that the uppercannot be caught between the fingerplates and ends of the side-lasting devices.

IIO

The toe-piece 21, having a curved and yieldiug face, is connected with the upper endof a spring, 22, attached to the toe-rest, the said toe-piece standing in its normal position in advance of the edges of the central fingers and fin ger-plates when most retracted, so that the upper on the last, when the same is being crowded below the level of the toe-lasting devices, will be acted upon about the toe of the last.

jnstably connected with the bar 28 by means The toe-rest is composed of a flexible plate, 23, mounted upon a stem, 24, fitted in a socket made in the toe-carriage, the lower end of the stem being sustained upon a spring, 25, herein supposed to be of india-rubber, so as to permit the rest to yield and descend snfficiently to enable the side-lasting devices to operate properly upon the upper at the edges of the inner sole, as hereinbefore described.

The pressers or downholds 26 27 are adof the screws or nuts 29 in slots 30. This bar 28 forms part of an arm, 31, having an elongated slot, 32, fitted to a roller, 33, on one of the rods 9. The short end 34 of this arm has an incline, 35, and a toe, 36.

A rod, 37, connected with the rod 9 is extended through one side of the slotted part of arm 31, as in Fig. 4, and outside of the said arm the said rod is provided with a spiral spring, 38. The lever 10, held up by the spring 39, has connected with it the wedge-barj to close the jaws, and this wedge-bar, at its upper end, has pivoted to it, at 40, a wedge-link, 41, provided with a cam-surface, 42. A roller, 43, is carried by that one of the shafts g opposite the one about which the arm 31 moves. The shoe upper and inner sole being upon the last and the last being supported in the machine, as in Fig. 2, the arm 31 is turned from its position in Fig. 3 to the position in Fig. 2, thedownholds or pressers coming in contact with and resting upon the face ofthe inner sole at two points between the ends ot'theinner sole. In thisposition the inclined end 35 of the arm 31, which is free to move,rests against the roller 43, as in Fig. 2. Now, ifthe treadle 10 isdepressed, the wedgebar J, as it descends, draws upon the link 41, while its notch 44 engages the roller 45, held in the arm 31, and while the rear side of the link bears against the roller 43, as in Fig. 2,

and consequently the arm 31 is so moved by crowding the inner sole and last-bottom down automatically to the proper level in a rightline, this beinginsured by reason oftheinclination of the opening 32 and-the Wedge 35 which acts upon the roller 43. The pressers remain at rest and hold the last pressed down so long as the straight face of the cam 42 acts upon the roller 45 and the incline 35 rests on roller 43. While-the hold-downs are so held stationary the wedgesj act upon the rollers 'i of the arms d and close the side-lastingjaws or devices to turn the upper over upon the inner sole, and as the lever 10 reaches the stop 8 the wedge 6 is drawn down to operate the levers 3 and 13 and close the central fingers of the heel and toe lasting devices over upon the heel and toe of the inner sole, after which the further descent of the lever 10 causes the wedge 6 to further move the levers 3 and 13 and cams M, to cause the portions 20 to act upon the arms u of the fingerplates 8 or s and close them radially over upon the face of the inner sole, and when the side and toe lasting devices are all shut in, as in Fig. 3, the cam-surface 42 passes beyond and from between the rollers 43 45, permitting the spring 38 to throw the lower end of the arm 31 into the positionshown in Fig. 5, which will cause the upper end of the arm 31 and the pressers or hold-downs to be autoi-natically thrown laterally away from above and in contact with the inner sole and shoe,leaving theupper laid over upon the inner sole and held by thejaws and fingers, free to be nailed or otherwise secured.

The finger-plates s are shown as folded, as at s so that they may yield vertically to a small extent, as is desirable for some classes of Work and uppers. The shank-pin b adj ustably connected with the arm a acts upon the inner sole at the shank of the shoe and keeps it down close upon the last, thereby facilitating tight lasting of the shoe at the shank.

I claim- 1. In a lasting-machine, lastingjaws or devices to press the edges of the upper over upon the inner sole, and two independently-adjustable pressers or downholds to bear upon the fore and rear part of the inner sole on the last, mechanismto operate the said parts in their .proper order, whereby therelative vertical positions of the bottom of the last with the inner sole thereon and the lasting jaws or devices may be changed to enable the bottom of thelast, with theinner sole applied thereto at a level above the line of action of the sidelastingjaws or devices, to be placed at or just below the line of action of the said lasting devices, and mechanism to automatically lock and hold the last depressed while the edges of the upper are laid over upon the inner sole.

2. In a lasting-machine, a jointed last-support located at the heel end of the last, and mechanism to press it upward, and a rear-part downhold whereby the heel end of the inner sole and last are forced closely in contact preparatory to lasting the boot or shoe, combined with an independent vertically-movable toerest and a downhold to bear upon the inner sole at the fore part of the last, substantially as described.

3. In a lasting-machine, independent vertically-movable heel and toe supports, side-lastsole thereon at the proper level for the action of the side-lasting devices to crowd the edges of the upper over upon the inner sole.

4. In a lasting-machine, a support for the last, side-lasting devices, substantially as desoribed, and elastic shank rubbers to rub upon the sides of the upper on the last, combined with fore and rear part downholds or pressers made vertically movable with relation to the line of action of the side-lasting devices, substantially as described.

5. In an organized lasting-machine, independent verticallyanovable heel and toe supports for thelast, fore and rear part downholds, side-lasting devices, and heel and toe lasting devices, each composed of radiallymovable fingers, to operate upon the upper at the heel and toe ends of the last, and mechanism to actuate the side-lasting devices to close the upper at its sides over upon the last, and separate cams to subsequently operate the radially-moving toe and heel lasting fingers to last the toe and heel of the shoe, substantially as described.

6. The arm 31 for the downholds, slotted and supported as set forth, combined with opcrating devices, substantially as described,

and a spring adapted to move downward the said arm and release it at the proper time, substantially as described.

7. A last-support and toe and heel downholds or pressers, combined with mechanismto move them verti aly and to automatically release the said downholds after the operation of the lasting devices, substantially as described.

8. In a lasting-machine, the adjustable-independent fore and rear part downholds and the toepiece mounted upon a spring arm, combined with toe-lasting plates and the toe-rest, to operate substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WM. E. FISCHER.
