CHARLES H. COOK, OF GARDINER, MAINE.

WELT-GUIDE FOR SHOE-SEWING MACHINES.

SPEGIFIGATION forming part of Letters Patent N 0. 738,886, dated September 15, 1903.

Application filed October 9,1902. Serial No. 126,464. (No model.)

To all whom it may concern.-

Be it known that LCHARLES H.000K, a citizen of the United States, residing at Gardiner, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Attachments for Shoe Ma chines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to shoe-making machines, but more particularly to attachments therefor, and has for its object to provide an attachment which is particularly adapted to be used on a Goodyear shoe-machine.

A further object of my invention is to provide a device which has in view the saving of the welt of the shoe, or, more specifically, that portion of the welt which is now wasted.

A further object of my invention is to provide a device which is easy of manipulation and which makes the welting of a shoe much safer to the operator of the machine.

With all these objects in view my invention consists in the novel arrangement of my attachment.

My invention also consists in certain fea tures and combination of parts, which will be first fully described and afterward specifically pointed out in the appended claims.

Referring to the accompanying drawings, Figure 1 is a view of my attachment, showing position of same on a Goodyear shoe-machine. Fig. 2 is a perspective view of attachment detached. Fig. 3 is a transverse vertical section of the same. Fig. 4 is a bottom plan of same.

Like numerals of reference indicate the same parts throughout the several figures, in which- 1 indicates the portion of the Goodyear machine which forms no part of my invention except in combination with my attachment.

2 is the welt-guide, showing space where welt comes through.

3 is the needle, and 4 the thread finger and looper.

5 is the back gage for shoe to rest against, and 6 is the thread.

7 indicates my attachment, which is com posed of the plate 8 and vertical wall 9. Passing through said plate is a small shaft 10, which is provided at its inner end with a finger 11 and at its outer end with a small lever 12. A nut or other fastening means 13 holds the same in position. 14 indicates a spring which passes from said lever to the machine proper, which normally holds said lever and finger 11 in a raised position and also holds the finger 11 at its innermost point, so that in order to move said finger transversely the lever 12 must be drawn outwardly at pin 15,1imiting the upward movement of the lever.

The attachment is secured to the machine by screws, as shown.

Having thus described the several parts of my invention, its operation is as follows: The shoe is placed on the machine in the ordinary manner, so that the needlewill pass through the welt about a quarter of an inch from its end. Place forefinger of left hand on lever 12 and press gently downward toward shoe, holding it there until needle feeds one stitch and then release lever, which leaves you ready for next shoe. This operation causes the finger 11 to press against the welt and hold it firmly in position while the nee dle takes first stitch.

By the present method it is necessary to hold the welt in position with the hand and that portion required for finger hold is wasted. Furthermore, the hand of the operator is in constant danger from the needle. With my attachment, however, this waste of welt and danger to the hand is entirely eliminated,

It will be noticed by referring to Fig. 4 that the finger 11 is capable of a transverse movement, as shown in dotted lines, so that the same can be made to engage any point transversely on the welt.

Having thus described my invention,l do not wish to be understood as limiting myself to the exact construction herein set forth, as

various slight changes maybe made therein by those skilled in the art which would fall within the limit and scope of my invention, and I consider myself clearly entitled to all such changes and modification.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. In a welt-machine, the combination with the welt-guide of a finger having means by which it is adapted to be pressed against the welt carried by said guide, and a shaft carrying said finger, a spring adapted to hold said finger normally in a raised position and for holding the same at its innermost point, a lever secured on said shaft for depressing said finger and for moving the same transversely against the action of said spring.

2. In a Welt-machine, the combination with the welt-guide, of a finger having means by which it is adapted to be pressed against the
