LASTING-MACHINE.

Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed June 29, 1915. Serial No. 36,951.

To all whom it may concern:

Be it known that I, JOHN H. HAMILTON, a citizen of the United .States, residing at Brockton, in the county of- Plymouth and State of Massachusetts, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, 1s a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines and is herein shown as embodied in means for use in positioning the shoe stock for the operation thereon of the gripper of a lasting and tacking machine which may be similar to that shown and described in United States Letters Patent No. 1,081,872, granted on application of E. A. Stiggins.

A feature of the invention consists in a novel organization comprising lasting means for engaging the margin of an upper, means for'engaging the margin of the innersole to hold it against the last bottom, and means for engaging the inner side of the upper materials and holding them for the action of the lasting means. A further feature of the invention consists in the combination with lasting means of stock positioning means which engages the inner side of the upper materials and which is operated automatically and directly by the lasting means. Another feature of the invention consists in improved mechanism comprising the combination with lasting means of stock positioning means arranged to operate between the shoe upper and innersole at that lateral side of the lasting means where it is out of the way of the operation of laying over the innersole the portion of upper acted upon by the lasting means. These and other features of the invention, which will be more fully understood from the following description and the accompanying drawings, are herein shown as embodied in a mechanism in which the lasting means is a gripper and the stock positioning means includes a stock presenter for engaging the inner side of the upper materials and lifting the upper up away from the innersole while the lower gripper jaw moves to gripping position under the upper, and an innersole feather edge holder located at one side of the gripper, the

presenter being operatively connected with the gripper to be moved thereby so as not to interfere with the operative movements of the lasting means.

Figure 1 is a perspective view of the shoe engaging parts of a hand method type of gripper lasting and tacking machine equipped with my. invention and shows a shoe being operated upon;

Fig. 2 is a side elevation of the gripper and work guiding devices.

The gripper 2 comprises a lower jaw 4 and a relatively movable upper jaw 6, the respective faces of the jaws being toothed or roughened to enable them to hold the stock between them securely when they close. A shoe bottom rest 8 is arranged to engage the innersole and is located to determine the vertical position of the shoe. A tack block 10 receives in a suitable tack pocket a tack from a separator 12 and is reciprocated over the edge of the shoe to wipe the upper into lasted position after the grippers have tensioned it, the tack being then driven by a driver 14 through the upper and into the lnnersole. In making welt shoes the tack is left upstanding as shown in Fig. 1 to facilitate subsequent removal. An edge rest 16 1s arranged to assist in positioning the work horizontally. These parts of the illustratlve machine may be substantially as in said patent.

The stock positioning means comprises a finger 20 secured to the work rest in downwardly and inwardly inclined position by screws 22 and slots which permit endwise adjustment of the finger. The inner end of the finger is adapted to engage the margin of the innersole, being shown as engaging the feather ofa welt innersole, and hold it down upon the last bottom so that the upper can be tightly lasted over the edge of the innersole. This finger has its innersole engaging end located at one lateral side of the path of the tack block which reciprocates across the sole edge to the lasting point, so that said finger is not in the way of laying the upper down and tacking it in lasted position. The inner end of the finger 2O pivotally supports'the lower end of the stock presenter 24: which extends upwardly and outwardly relatively to the machine and has sliding support in a bearing block 26 which is pivotally mounted on the support for the lower gripper jaw. By reason of thls connection with the gripper the gripper operates the stock presenter by oscillating it about the pivotal connection at its lower end with the finger 20.

In the use of the invention, a shoe is presented to the machine as shown in the drawings. The finger 20 contacts with the margin of the innersole at one side of the lasting point and presses it down upon the last bottom and holds it from being lifted or displaced in the lasting "operation. The stock presenter 24 extends under the upper and engages the inner side of the upper materials to hold them up for lower jaw 4 to get under them as the jaws move to upper seizing position. When the gripper is upraised and is moved over the shoe bottom in stretching and overdrawing the upper, sliding motion occurs between the pivoted block 26 and the presenter 24 and the presenter is moved downwardly so as not to interfere with the overdraw movement of the gripper, but the lower end of the presenter remains continuously under the upper materials at one side of the lasting and tacking point. After the gripper has released the upper and the fastening tack has been driven the shoe is fed along lengthwise by the operator for the next lasting operation. The lower ends of the members 20 and 2% remain, however, under the upper, the finger 20 holding the innersole margin down and the presenter 24: holding the upper materials up so that they will not be engaged by the jaw l as it descends and moves toward the edge of the shoe. The supporting points for the presenter in the finger 20 and the bearing 26 are so located and the presenter is so shaped that the presenter, which has a smooth up per engaging face, holds the upper above the toothed face of gripper jaw 4, as shown in Fig. 2, while the grippers move to upper seizing position.

Having explained the nature of my invention, I claim as new and desire to secure by Letters Patent of the United States:

1. In a lasting machine, the combination with a gripper having overdraw pulling movements and operating mechanism to return it to upper seizing position and close it after each pulling operation, of means operated by the gripper to engage the upper materials and hold them where they will not be engaged by the lower jaw of the gripper during such return movement and until the gripper closes.

2. In a lasting machine, the combination with a gripper and operating mechanism to return it to upper seizing position and close it after each pulling operation, of means connected at one end with the lower gripper jaw and having its other end continuously under the upper materials and extending in position to hold the upper materials above the lower jaw while the gripper returns to upper seizing position.

3. In a lasting machine, the combination with a gripper and operating mechanism to return it to upper seizing position and close it, after each pulling operation, of stock positioning means including a finger having an end located to extend between the innersole and the upper of a shoe presented to the machine, and a cooperating device pivoted to said end of the finger and maintained relatively to the gripper in position to hold the upper out of engagement with the lower jaw of the gripper while the gripper is moving to upper seizing position.

4.
