LAsTlNe-MACHINE.

SPECIFICATIONforming part of Letters Patent No. 244,714, dated July 19, 1881.

Application led June 21, 1881. (Model.)

To all whom. it may concern:

Beit known that we, GEORGE W. COPEL'AND, of Malden, MATTHIAS BROCK, of Boston, and JOSEPH E. Cnrsrgof Boston, all in thel State v of Massachusetts, citizens of the United States,

have invented a certain new and useful Improvement -in Boot and Shoe Lasting Machines, of which the following is a full, clear, and exact description, reference being had to ro the accompanying drawings, forming a part of this specification, in explaining its nature, in Which- Figure l is avertical section of the machine. Fi g.2 is a plan thereof. Fig. 3 is a detail view, enlarged, representing a portion of the machine hereinafter referred to. Fig.4is a plan, enlarged, of a portion of the mechanism below the line :v m of Fig. 1. Y This invention relates more especially to de- 2o vices for lasting the toe and heel portions of boots and shoes, and it embraces, first, means for holding the upper tothe side of the last, about the toe or heel, p'rior to the folding of the edge thereof upon the surface of the in-` sole; second,foldin g-plates, or devices forfoldi: ing the edge of the upper upon the insole, and a 4gang or group of devices for driving fastenings simultaneously or by a single impulse after the folding-plates have performed their 3o functions, andl which may or may not be placed in position to be operated by them; third, the construction and arrangement of parts hereinafter more fully described. v

Inthe drawings,Ais the last. It is mounted at the heel upon the pin a of the jack A', and at the toe upon the toe-support c of the jack. The pin and toe support ofthe jack project upwardly from the bed a2, which is pivoted, so as to be revolved, at a3' to the sliding plate c4. 4o This sliding plate has ahorizontal movement,

in suitable guides, toand from the lasting devices.

The appliance or device'for holding the edge of the upper against the side and end surface 45 of the last consists in two curved arms, B B',

each of which is sha-pcd and conformed to that portion of the side and end of the last upon which itis to operate. .Theymaybe made of steel, sufficiently thin to conform by yielding to the surface of the last; or they may be made of metal, and be lined upon their surfaces with rubber or leather orv other material or they may be made in any other suitable way. They are each mounted on a yielding or spring arm, b, and one is arranged to project slightly in advance of the other, so that upon the presentation of the last and upper thereto they shall be brought in contact with the holding device upon one side and corner, and the upper drawn up by pinchers, or in any other suitable way, upon that side and corner immediately before being brought, in contact, and while being brought in contact, with said advance holding device; and that portion of the upper having been drawn -up and tted and being held by the holding device, the last and upper are then moved to the other upper-holding device, adapted to act upon the other corner and side of the last, and the upper is pulled up by' pinchers, or any other way, immediately before and while being brought in contact'therewith, and is held up thereby afterward until the action of the folding-plates; or, in other words, the two upper holding or clamping devices are so arranged in relation to each other and to the jack that that portion 4of the'upper about one corner of the last is first ttedto the end and side surface ofthe last, and held up by the holding-plate; and

out departing from the spirit of this portion of our invention.

' The next feature of ourinvention has to do with thefolding of the edge of the upper upon the insole at the toe and heel, and the fastening of the edge thus folded to the insole by a group or gang of fastenings driven by-a sin-v gle impulse or simultaneously.

We have represented the jack as capable of being reversed or revolved on a horizontal plane, and we have represented the springarms carrying the upper-holders B B as secured to the block or post b. This block or post projects downwardly from the plate or bed C, which is adapted to slide horizontally in suitable ways, c, in the frame c' of the niachine, and this frame c is provided with the post c2, which enters the socket c3 on the standard c4, and furnishes means whereby the frame'- bed and appendages may be revolved. One end of the sliding bed or plate carries the toelasting plates D D. These plates are pivoted at their inner ends to the post d, and upon the inward movement of the bed or plate are caused to be shut or closed upon the surface of the insole by means of the rolls d2 d3 upon the frame c. The outer surface of the plates coming in contact with the rolls as the bed or plate slides inwardly, causes the plates to be closed. The folding-plates are provided with a series of holes or nozzles, c, which are arranged a little back from the edge of the plates, and in these holes or nozzles a corresponding series or group of drivers, E, are arranged to be reciprocated by any suitable means; and we describe as one the attachment of the drivers to the hinged blocks e', and the use of the rod d, in connection with a treadle when opcrsted by foot-power, and a cam or lever when operated by motive power, for reciprocating said blocks. In this event the blocks would be hinged upon the rod d, a'nd would be provided a vertical movement.

The spring c2 may or may not be used for returning the blocks to their normal position in connection with the mechanism herein described for reciprocating them. Each driveway, nozzle, or hole c has opening into it a feedpassage, c3, preferably horizontal, by which the fastenin gs are fed to the drivers.

The fastening we prefer to use is that shown and described in Letters Patent No. 197,609, granted said Copeland and Brock, and dated November 27, 1877, and No. 186,663, granted said Copeland.

The shape of feedway, the device for feeding said strip, and the manner of driving tacks therefrom are shown and described in Letters Patent No. 197,608, granted Copeland, Woodward and Brock, dated November 27, 1877; and in No. 284,854, granted said Copeland and Brock, dated November 30,1880; and we need not, therefore, further describe the construction and operation of the fastening-driving mechanism, exceptin gto say that such devices, when used for driving fastenin gs in this invention, are arranged in gangs or groups, each device having a nozzle, feedway, feed mechanism, and driveway substantially like those described in said Letters Patent, the drivers, however, being arranged to be operated together, or by a single impulse, the feedways being converging, or substantially converging, in direction, and the nozzles preferably being formed in the folding-plates, and being placed or moved into position in relation to the edge of the last by them.

l n operation the upper, being mounted upon the last and secured thereto temporarily at the toe and heel, is, with the last., placed upon the jack, and the upper, last, and jack are then moved to the upper-holding device, and the upper having been tted to the sides and ends, and being held by the holding device, the edge to be folded being above the surface of the insole and in a vertical position, the upper, last, jack, and upper-holdin g device are then moved horizontally under the folding-plates, and by their continued movement cause the foldingplates to be closed upon the surface of the insole, thereby folding the edge of the upper thereon, and at the same time bringing the group or gang of driving devices in proper position for driving the group or gang of fastenings. lhe group or gang of fastenings is then driven simultaneously or by a single impulse.

This description of the operation of the machine answers as well for the heel lasting and securing appliances as for the toe, and the toe having been lasted, the only thing necessary to do to last the heel is to reverse the jack and reverse the frame c', and the other end of the frame, which is provided with the heel-lasting appliances, which are in every respect, excepting that of shape, a counterpart of the lasting devices already described, vare brought into the position occupied by the toe-lasting devices, and the heel is then lasted, as above described.

The heel-lastin g devices, being secured atlthe end of the sliding plate C, are by the movement of the toe-lasting plates inwardly caused to assume, automatically, the proper position which the apparatus should bear at the commencement of the lastingthat is, the upperholding devices are thrown forward and the folding-plates are opened.

We have shownthe springs f attached to the folding-plates and to the sliding plate'for automatically opening the plates; but any other suitable equivalent device may be employed.

Of course we do not confine ourselves in the practice of this invention to the arrangement of the folding-plates and fastening-driving devices herein described, or to the use of fastening-driving devices adapted to drive only the Copeland tack-strip, so called; but We may use, in combination with the folding-plates, any arrangement of devices for driving fastenings of any description desirable, and may give them any suitable location and movement in relation to the lasting-plates, the essential features being that the devices for driving fastenings shall be so constructed and located that they can be brought in position either by their movement in relation to the last or the movement of the last in relation to them, and the fastenings driven simultaneously, or by a single impulse, while the lastingplates are IOO IIO

holding the turned-in edge upon the surface of the insole. v

The advantages of this invention are that the toe and heel, or either, can be lasted much more rapidly than by the ordinary toe and heel lasting mechanism.

In lieu of reciprocating the drivers, as herein described, We mention the use of a hainmer, bywhich the blocks supporting the drivers may be driven downwardly against the lstress ofthe spring e2.

Having thus fully described our invention, We claim and desire to secure by Letters Patent of the United States- 1. In a machine for lasting the uppers of boots and shoes, the upper-holding devices B B', one of which is arranged in advance of the other and adapted to operate or be operated upon before the other, all `substantially as and for the purposes described.
