Claims.

The present invention relates to sole marking machines for use in the manufacture of shoes.

It has been found desirable in performing certain operations around the bottom margin of a 5 shoe such, for instance as the sole rounding or edge trimming operations on an outsole, and

particularly where these operations are performed by the use of automatic machines, to provide a templet located in proper position on the 1 10 outsole, and to utilize this templet as a guiding means to control or determine the outline on the shoe followed by the rounding or trimming cutter. For the successful use of such a templet, it is necessary that the templet be located in exact f l5 predetermined position with relation to the last contours of the shoe in order that the edge produced by the cutter may be used as a guide in subsequent operations, as for instance the outseaming operation or that the edge produced by f the cutter or the outiine followed by an oper- 30 contours of the shoe.

W ith this object in view the present invention contemplates the provision with marking means adapted to form a templet positioning surface on a shoe sole, of means for determining the relative positions of said marking means and the shoe to cause a templet positioning surface to be formed on the sole at a predetermined point with relation to the last contours of the shoe. Broadly considered, the invention contemplates the provision of any suitable means for marking the sole, but preferably this marking means consists of a marker adapted to form an indentation or prick mark on the sole. Also, in its broader aspects, the invention contemplates the provision of any suitable means by which the marking device and shoe can be readily and accurately brought into a position to cause the indentation or other templet positioning surface to be formed at the desired point on the sole. In the construction hereinafter described as embodying the invention, however, this result is secured by means comprising gaging devices adapted to engage a last contour of the shoe, and position the shoe with relation to a relatively stationary marking device. i i

The templet in connection with which the marking machine is particularly designed to be used is located upon the shoe sole by means of a pin or projection on the templet adapted to engage the indentation made by the marking device, so and also by means of a slot at its rear end adapted to engage a pin projecting from the last through the inner and outer soles of the shoe. In the marking machine hereinafter described, this pin is also utilized in locating the shoe with relation to the marker, a guiding slot in a portion of the marking machine being provided to receive the pin, and thereby cooperate with the gaging devices in locating the shoe in the proper position with relation to the marking device.

The present invention also consists in certain devices, combinations, and arrangement of parts hereinafter described and claimed, the advantages of which will be readily understood from the following description taken in connection with the accompanying drawing, in which Fig. 1 is' a plan View of a marking machine embodying the several features of the present invention; Fig. 2 is a view in side elevation and partly in section of the parts shown in Fig. 1, a lasted shoe being positioned in the machine preparatory topricking the outsole; Fig. 3 is a sectional View in side elevation taken on the line 3-3 of Fig. 1, with the parts shown in the position they occupy at the completion of sole pricking operation; Fig. i is an underneath plan view of the marking machine; and Fig. 5 is a plan view of the shoe after the pricking operation.

Referring to the drawing, the frame of the marking machine illustrated therein consists of a plate 6 extending upwardly and outwardly in a slightly inclined position from a boss 8 through which a bolt 10 passes by means of which the frame is rigidly secured to a suitable xed support 12. The pricking pin for forming a templet positioning surface on the outsole of a shoe is indicated at 14 and is mounted to reciprocate in a guideway formed in the plate 6. The lower end of this pin is pointed in order to form an indentation in the shoe sole and the upper end of the pin is provided with a iiange 16 beneath 100 which a spring 18 is located. This spring surrounds the pin 14 and is received in a recess formed in a boss projecting upwardly from the plate 6. The pin is thus normally maintained 105 yieldingly in raised position by the spring.

The shoe to be marked is held by the operator with the tread surface of the sole uppermost and is resented to the marking devices with the toe portion or forepart of the shoe sole beneath the 110 plate 6, being located in proper position by means hereinafter described.

For actuating the pin 14, to indent the shoe sole, an actuating lever is provided which is pivotally mounted about midway its length between arms projecting rearwardly from the plate 6. At its forward end, the lever 20 is provided with a spherical or ball-like portion which engages a slot in the lower portion of the pin 14. The rear portion of the lever 20 extends over the heel portion of the shoe which is presented to the marking device so that an upward movement of the heel portion or the shoe, after being located in proper position with relation to the pricking pin, actuates the pin to indent the sole.

To locate the shoe in proper position with relation to the sole pricking pin, gaging devices are provided to engage both the toe and heel portions of the shoe.

The gaging devices which operate at the toe portion or^ the shoe comprise an end gage 22 to contact with the last supported upper at the extreme toe end or" the shoe, and side gages 24 to contact with the shoe at each side of the toe portion. These gages contact with the last supported upper and thus locate the shoe and the surface of the outsole in predetermined position with relation to the last contour of the shoe. The gage 22 determines the longitudinal position of the shoe and is formed on a block 24 which is secured to the plate 6 so as to be capable of an adjustment longitudinally of the shoe by means of a bolt 26 passing through a slot in the plate. The gages 24 act to position the toe portion of the shoe laterally and are carried upon arms 28 pivotally mounted upon the plate 6. These arms are yieldlngly forced toward each other by means of a connecting spring 30 and in order to cause the arms to move in unison toward and from each other so as to locate the toe portion o the shoe with relation to the indenting pin, their hubs are provided with inter-meshing gear segments 32. The gages 24 are in the form of rolls and as the shoe is inserted into the machine these rolls extend beneath the projecting edge of the shoe sole and bear at their upper ends against the under surface of the sole. A spring plate 34 is secured to the under surface of the plate 5 of the frame and at its rear end bears against the tread surface of the shoe sole adjacent the toe and acts to force the shoe yieldingly down into contact with the upper ends of the rolls 24.

The gaging devices for the heel portion of the shoe comprise a slot 36 formed in the rear end of the pin actuating lever 20 which slot is shaped to receive the head of a pin 38 projecting from the last of the shoe through the outsole of the shoe. This pin, in the construction illustrated in the drawing, is a jig pin utilized in locating the outsole in proper position on the shoe, as fully explained in the patent to George E. Warren, No. 1,706,504, dated March 26, 1929.

To mark the outsole of a shoe, the shoe is inserted in the machine so that the forked portion of the lever 20 engages with the pin 38 and the shoe is advanced until the toe portion of the upper engages with the block 22. At the same time, the toe is positioned laterally by the yielding engagement of the rolls 24 with the sides` of the shoe upper. After the shoe has been positioned in this manner, the heel is raised sharply by the operator, thus causing the lever 20 to turn about its pivot and depress the marking pin 14 to indent the outsole, which is supported against the downward thrust of the pin by the gage rolls 24.
