JAMES E. JACKSON, OF LYNN, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE UNITED SHOE MACHINERY COMPANY, A CORPORATION 0E NEW JERSEY.

MACHINE FOR LASTING BOOTS ANI) SHOES.

LOMLZ.

To all whom t may concern.

Be it known that I, JAMES E. JACKSON, of Lynn, in the county of Essex and State of `intassachusetts,` have invented certain new and useful Improvements in Machines for Lasting Boots and Shoes, of which the following is a specification.

The present invention relates t-o machines for lasting boots and shoes, and it is embodied in a. machine of thattype which include sewing mechanism.

A principal object of this invention is to provide a novel mechanism7 which is herein shown as arranged in combination with other usual elements of a machine of this type, for drawing the upper overthe last which shall be both simple and effective.

"With this and other objects in view7 the present invention is shown as embodied in mechanism which comprises a movable member, one end of which is adapted to have a non-slipping engagement with, and preferably to penetrate, the upper of a shoe being lasted, together with mechanism for actuating this movable member in one direction to cause it to engage the upper and then in a different direction to draw the upper over the last. Preferably, an abutment is provided to co-actwith said member in such a way as to support the upper against the thrust of the movable member and insure its proper engagement with the upper. ln the illustrated use of the invention the abutment also may include means for engaging the shoe bottom to hold the shoe against displacement by the strain eX- erted on the upper by the uppenpulling member. In the construction shown, the portion which forms an abutment to resist the lateral thrust of the movable member against the upper and the means for resisting upward displacement of the shoe are rigidly connected so that the upper-engaging member moves with relation to the upper-supporting face of the abutment for pulling the upper, but this is obviously not essential to the invention. Preferably also and as herein shown, the upper-supporting face of the abutment is provided with a recess in alinement with the upper-engaging member which permits the tooth or point, with which said member is preferably provided, to project through the upper if desired 'to enable said member to engage the upper more securely. The provision of the Specification of Letters Patent.

Application filed July 2, 1897.

recess in the upper supporting face of the abutment also has the advantage, when as herein shown the upper-engaging member moves relatively to the abutment to pull the upper, that said f-ace offers less resistance to the movement of the upper or lining thereover.

Another feature of this invention is found in the provision of a mechanism which in addition to engaging or engaging and pulling a portion of upper material as described or otherwise is also adapted to grip and separately hold a second portion of shoe stock. In the'example shown, the second portion of shoe stock is an upstanding lip of the shoe innersole and it might on other work be any portion of shoe stock located adjacent and approximately parallel to the upper as, for example, a shoe lining in work in which it was desirable to pull the upper independently of the lining. As herein shown, the engaging and holding devices are adapted not only to'hold separated two portions of stock, but to pull one of said portions of the stock relatively to the other portion. To this end the member which has been referred to as an abutment having an upper-supporting portion cooperating with the upper-engaging and penetrating member has also in the illustrated construction a stock engaging surface on its opposite side and a gripper member is arranged to cooperate therewith to seize the innersole lip or other second portion of the shoe stock. This produces a construction having two outer jaws and an intermediate aw or member having stock engaging surfaces on its opposite sides which may be of appropriate similar or dissimilar formation according to the nature of the Work to be done by them. As herein shown, the surfaces of the outer and intermediate jaws that engage the innersole lipV are ribbed as distinguished from the described formation of the other two cooperating surfaces which engage the upper. It is to be noted that it is characteristic of the upper-engaging devices that the outer member is provided with a non-slipping surface which may indent or penetrate the engaged surface of the stock while the cooperating surface of the abutment is relatively smoother or of less holding power. An advantage which may be secured from this fact is that, when lasting a lined shoe in which the upper and lining are inserted bejaw receives an upper pulling movement iny addition to an engaging movement While the intermediate jaw or abutment is stationary.

The length of this stock engaging movement, or the formation of the engaging surface of this outer jaw, may be such as to insure a non-slippiiig engagement or partial or complete penetration of the upper leather without penetrating or otherwise so seizing the cloth lining that the latter may not drop behind the leather during a part or the whole of the pulling movement. It is believed to be new to actuate one of two opposed gripping members relatively to the other in the direction of and during the pulling strain to effect stretching of one of two portions of the stock, as the shoe upper, relatively to another portion such as the shoe lining, or for any other analogous purpose. It is also new to provide outer jaws cooperating with an intermediate jaw and means for actuating the outer jaws in different directions. In the instance shown, one outer jaw has only a gripping movement while the other jaw has also a pulling movement. It is characteristic of the illustrated construction that the jaws grip one portion of the stock, as t-he upper in advance of the point lengthwise of t-lie shoe at which the other portion, which is the iniiersole lip, is gripped. For this purpose the intermediate member has a gripping face on one side which is in advance of the gripping face on its other side. In the machine shown, this has the advantage that the outer, lip engaging jaw is removed fai' enough from the upper pulling and securing point to give ample space for the manipulation of the needle of the stitching mechanism.

Other features of this invention, including certain combinationsof parts and more important details of construction, will be set forth in the following description and included in the accompanying claims.

Reference is to be had to the accompanying drawings and to the letters and figures marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may be, wheiever they occur.

Figure l of the drawings is a sectional view through a sewing machine for lasting boots and shoes to which my invention is applied for the purpose of illustration.

Fig. 2 is a perspective View of the stock engaging members or jaws. Figs. 3 and 4: represent sections through a last having a sole and upper thereon illustrating the movement of the upper pulling member. Fig. 5 shows a complete machine in side elevation. Fig. 6 is a detail view illustrating, in front elevation, the relation of the needle and stock engaging members or jaws.

The mechanism which I shall now proceed to describe is more especially adapted for use in the machine illustrated and described in my co-pending application for Letters Patent of the United States, Serial No. 630,153, filed March 31, 1897, to which reference may be had for a complete descriptioii of the various parts of the inacliine and the movements thereof. Inasunich as this present invention relates primarily to the mechanism for gripping the shoe stock and stretching the upper, I have not illustrated in detail all of the other paits of the machine, such as the stitch forming mechanism, the feeding devices, etc., which are fully shown and explained in said earlier application.

Referring to the drawings,-a indicates a base plate from which rises the gooseneck a upon which is mounted the mechanism for sewing the upper to the insole which includes a needle 2, an awl 3, a looper 4, and devices for actuating them. This mecha-nism, as well asI the mechanism for feeding the work (not shown) may be of any usual or suitable construction, but preferably are such as are fully described in my prior application.

Mounted in bearings in the frame which supports the base plate a. is a driven shaft Z which is provided with a cam b having a cam groove Z22 in one face and another cam groove Z13 in its opposite face. Mounted in a standard a2 projecting up from the base plate a is a stud shaft o upon which is fulcrumed a lever or carrier c. This lever is formed in its forwardly projecting end with a groove c2 in which is placed a slide c3 held therein by a slotted plate c4 through which projects a lug c5 secured to the slide o3. On the end of the slide is placed an upper-engaging device consisting of a small jaw or plate Z adjustably secured to the slide c3 by screws c@ passing through slots in the plate. As shown, this plate or jaw is formed with a forwardly projecting tooth or point d, which is adapted to indent and, it may be, to penetrate completely through the upper so as to obtain a firm grip upon the same.

The lever c is rocked about its fulcrum c by means of a connecting rod c having a yoke e embracing the shaft and provided with a roller extending into the cam groove b2. The rod e passes through an aperture in the rear end of the lever c and is threaded at its upper end to receive a nut e2. A sleeve e3 is placed loosely upon the rod with one end abutting against the nut e2. Telescoped in the other end of the sleeve is another sleeve e4 having its lower end pressed yieldingly against the lever 0 by a coiled spring e5 surrounding the rod e within the sleeve e3. The rear end of lever o is pressed normally upward against an adjustable stop It? by a spring 7L.

The member or jaw d is given a longitudinal movement independently of its supporting lever 0 by means of the following devices: An arm f is fulcrumed loosely upon a stud f and has its upper free end connected with the lug c5 by a link f2. A lever g is fulcrumed centrally upon t-he stud f and is provided at its lower end with a trundle or roller projecting into the cam groove 3 shown in dotted lines in the disk b. The upper end of. the lever g is laterally extended as at g and is provided with forwardly projecting flanges or lugs g2 g3, a spring g* being interposed between the lug (2 and the arm f, which is arranged between said lugs.

With the above-described construction it will be seen that as the cam disk rotates the member or jaw Z will be reciprocated in a plane substantially parallel with the bottom of the last by slide c3 actuated yieldingly from the cam groove b3, and that it will be independently and yieldingly rocked with its carrier o, so as to carry it upwardly away from the last. The extent of this upward movement will be varied by adjusting the stop h2 according to the requirements in lasting different slices.

The member which forms an abutment for coperating with the movable stretching member rl, is herein shown as stationary or xed in position, although that is not essential to the invention. The member z' comprises a supporting device which coperates with the upper stretching member to hold the upper against the thrust of such stretching member. This device is shown as mounted rigidly upon the member and is, therefore, stationary, but this arrangement is not essential. To this end, as herein shown, the member has a laterally extending web which forms the upper supporting device. This web is preferably recessed or slotted as at 2 in Fig. 2, this slot being in alinement with the tooth or point CZ of the movable member Z so that, as this member CZ is moved forwardly by its actuating mechanism above described, if the point (Z penetrates through the upper resting against the supporting device z it may extend into the slot 2, as shown in Fig. 4. If there is a lining of cloth or other material it may be bent into the slot 2 and thus a non-slipping engagement of the tooth or point therewith provided while yet seizing the lining with enough force to cause it to be pulled sufliciently to straighten any wrinkles therefrom when the upper is stretched. The stationary member also, in combination with a movable jaw 3, constitutes a pair of grippers for clamping the channel lip or tape forming a part of or secured to the sole of a shoe and holding said lip or tape in position to be engaged by the stitching mechanism. The movable jaw 3 is formed on a lever which is operated through suitable connections, fully shown in the drawings, by the cam surface formed on the edge of the cam disk b.

The stock engaging devices of this pres ent invention are an improvement upon the earlier construction in that, among other things, only three members are required instead of four as heretofore for seizing separately the parallel adjacent upper and innersole lip and pulling one of said adjacent portions of the stock with relation to the other. The use as described of one intermediate jaw with two coperating outer jaws simplifies the construction; and the single pulling jaw coperating with the fixed intermediate jaw produces good results and has, in the illustrated and other uses, many advantages some of which have been pointed out in the earlier portion of this description.

In the operation of the mechanism above described as equipped with this invention, the gripper jaw 3 is actuated to grip between it and the stationary member the lip projecting from the sole, so that the work is held firmly. The movable member or jaw l is projected forwardly to cause its tooth or point Z to engage, and preferably to penetrate and it may be to project through the upper B near its edge and thus, it may be, stretch the upper over the last to some extent, after which the point (Z is raised to effect or to complet-e the stretching of the upper, the stationary member serving to maintain the upper securely engaged upon the tooth of jaw Z and to prevent the rising of the last. The axis of motion of the jaw CZ, found in the shaft c, is above the jaw so that as the jaw is raised (Fig. 4) the hold upon the leather is tightened. The timing of the cams is of course arranged to cause the jaw d to seize the upper before it rises to stretch the upper and to release the upper before it descends. The jaw 3 is actuated to grip the innersole lip and thereby position the shoe before the jaw CZ seizes the upper', see Fig. 3, and the formation of the edge cam b causes the jaw 3 to hold the shoe during the major portion of the cycle and until after the jaw (Z has been retracted whereupon it releases the lip to permit the relative change of position between the shoe and stock engaging devices which is required for feeding the shoe. The needle 2 of the stitch-forming mechanism passes through the stretched upper and the lip adjacent to the jaws d, z" before the j aw [Z is drawn rearwardly to disengage the upper and t-hen is carried downwardly. The gripper having next been retracted from the work, a cycle of operations of the parts to which this invention relates is completed.
