LASTlNG- MACHINE.

SPECIFICATION forming part of Letters Patent No. 286,898, dated October 1 6, 1883,

Application tiled August 17, 1883. (No model.)

To all whom it may concern:

Be it known that I, MATTHIAS BROCK, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvementin Lasting-Machines, of which'the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to improve Io that part of a lasting-machine which lasts the heel of the boot. or shoe. i

In lasting-machines as now commonly made the quarter of the shoe is held against-the last by a U -shaped spring or clamp, which isuforced up against and so as Vto surround the said quarter, the said spring extending about the quarter substantially as far as does the usual heel-stiffening; but such spring or clamp is objectionable, for the `reason that it fails to 2o press the quarter at the end of the stiftcning into the hollow at the inner side of the shank of the last. To overcome this lack of proper fit of the shoe at the inner side of the shank of the last, I have provided the machine with 2 5 a shortened clamp, which is adjusted to eX- tend about the quarter only at the heel of the last, and, co-operating withthe said shortened clamp, I have employed stiffening-pressers, which will preferably be hinged or pivoted to 3o the shortened clamp, so as to be closed upon the quarter opposite the ends of the stiftening after the shortened clamp has come to a seat upon the quarter immediately at the heel end of the last, the said stiffening-pressers be- 3 5 ing movable independently of the said shortened clamp, as will be described.

My invention consists, essentially, in the combined shortened clamp and stiffening-pressers adapted to hold the upper and stiffening propio erly upon the last for lasting; also, in the combination, with the shortened clamp and stiftenin g-presser, of the last, lasting-j ack, and means to operate them, substantially as described, and the stiffening-pressers; also, in means for ,4 5 holding and adjusting the tipping-head.

Figure 1 is a partial side elevation of a sufficient portion of a lasting-machine to enable one conversant with the art to understand my invention; Fig. 2, a top or plan view of Fig. 5o l. Fig. 3 is a view of Fig. 1 with the last and toe-rest removed, the column being in vertical section opposite the cross-head which carries the jaws. Fig. 4 is an outer sideV view of the shortened clamp and stiftener-presser, and Fig 5 a top view of Fig. 4. y

This invention is animprovement on the mechanism described in United States Letters Patent No. 208,156, and in No. 213,857, to which reference may be had.

In this invention the Icross-head A, which slides vertically in ways formed in the column BX, thejaws C2, and the sliding cam-plate M are substantially as in the Patent No. 213,857, referred to, and the oscillating plate G, the converging folding-plates E F, and the downhold C are substantially as in the saidPatent common to the said patents are designated by like letters, except in the case of jaws C2, which latter, in the said No. 218,857, is marked-E, and the column BX, which, in the Patent No. 208,156, is marked B. As in the Patent No. 213,857, in practice the jaws C? will carry the girth-supporting fingers. The frame-work B in the column B supports at one end the carriage B2, having cheek-pieces B3, slotted at 2, and near its center the said carriage has a bracket, B", slotted at 3.A rIhe oscillating plate G is pivoted at its outer ond, at 4, upon the carrier H, designated by same letter in the Patent No. 208,156, and at its front end to a part of the said carrier at 5. (See Fig. 3.)

The device H, which I have herein designated by the name carri er,77 is provided with a bolt, which is extended through the slot 3, and with a bolt, b, which is extended through the slots 2 in the said cheek-pieces, and by means of the said bolts the said carrier may be adjusted to place the said oscillating plate in any desired position with relation to the curve or spring of the heel-seat, or to the curve of the toe of the last of the carrier when being used in connection with converging folding plates adapted to act upon the toe of the last.

ted bracket B* and slotting it and the cheekpieces, as shown, and adjusting the carrier H thereon, as described, I am enabled to do away with the slotted lever, its connecting-levers,

No. 208,156, and herein the parts referred to as By providing the carriage B3 with the slotlink, and hand-wheel, and other parts described in the said Patent No. 208,156, thus greatly simplifying the parts and reducing its cost.

The last containing the shoe or upper S to be lasted will be supported in any usual manner on a heel-pin, c, and the rest c.

The carriage B2 has two lugs7 6, that receive studs 7, connected with movable arms d. 'Ihese arms dhave connected with them by screws 8 the two stiffening-presser-moving levers c, the upper ends or" which,at the proper time, are moved toward and made to act against'the stiffening-pressers ff, pivoted at Vl() upon the shortened U -shaped clamp g, pro- Yvided with ears g', and pinned upon the post g2, attached to the carriage B2.

rIhe clamp g and pressers f are lined with a strip of leather or rubber, f2, pinned to the pressers f, and acting as an apron to cover the joint between the said clamp and pressers to avoid marring the quarter of the shoe. Each lever c, at its back, has a curved stem, which receives and forms a guide for a spiral spring, e3, longer than the said stems, and each of the said springs is extended into a socket or recess made in one of the arms d.

The arms d are closed or moved toward the last by the projections d d, bolted each to a jaw, E, by bolts d2, and each arm d is acted upon by a projection, d', just as the jaws of the girth-lasting device completes its downward andV inward movement, the carriage B2 having been, however, previously moved forward or inward to cause the shortened clamp g to clamp the quarter against the heel of the last. The inward movement of the stiffeningpressers f as about their pivots 10 causes the quarter at the ends of the stiffening to be pressed into the hollow of the shank of the last. rIhe levers d have sufficient movement to always move the arm c in front of it far enough to enable it to act upon and press the presser fully into the hollow at the inner side of the shank of the last; but as right and left hand shoes are lasted each presser has at different times to move in more or less, according to whether a right or left hand shoe is being lasted, and to compensate for the difference in the shape of the last is the function of tion of the quarter of the shoe at the ends of 6o the usual heel-stiffening, combined with folding-plates or devices to turn the edges of the quarter over upon the inner sole, substantially as described.

2. In a lasting-machine, the shortened U- shaped quarter-clamp and the pivoted pressers f thereon, combined with the lining to cover the joint between the said pressers and shortened clamp, and with folding-plates or devices to lay the edge of the quarter over upon the inner sole, substantially as described.

3. In a lasting-machine7 the shortened U- shaped quarter-clamp and the pivoted pressers f thereon, combined with the pivoted arms d and stiffener-presser-moving levers, substantially as described.

4. In a lasting-machine, the shortened U- shaped clamp and stiffener-pressers, levers e, arms d, and interposed springs, combined with means, substantially as described, to actuate the said arms, as and for the purpose set forth.

5. In a lasting-machine, the movable carriage and the movable arms ,pivoted thereon, and the levers c and springs c3, combined with the stiffener-pressers and U -shaped clamp, to operate substantially as described.

G. The movable carriage provided with the cheek-pieces and bracket B, combined with the carrier H 'for the oscillating plate G2, to permit the carrier to be adjusted, as shown and described.

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

MATTHIAS BROCK.
