PRESSER-FOOT AND WELT- GUIDE COMBINED.

SPECIFICATION forming part of Letters Patent No. 366,259, dated July 12, 1887.

Application filed March 4, 1886. Serial No. 193,954. (No model.)

To aZZ whom, it may concern:

Be it known that I, ELBRIDGE 0. Ross, a citizen of the United States,residing at Stou ghton, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Presser-Foot and WVelt- Guide Combined; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompa- 1o nying drawings.

This invention relates to improvements in pressenfoot and welt-guide combined, for the purpose of guiding a welt onto the bottom of a lasted shoe-upper while it is in the act of I 5 being sewed to the upper and insole of a boot or shoe, as will hereinafter be more fully shown and described, reference being had to the ac companying drawings, where- Figure 1 represents a front view of the device, showingit in'position relative to neighboring parts of a McKay wax-thread sewing machine. Fig. 2 represents a plan view of the device, and Fig. 3 represents a bottom view of it. Fig. 4 represents a side view of the device as seen from X in Fig. 1; and Fig. 5 represents a longitudinal section on the line A B, shown in Fig. 4.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In Fig. 1, a is the bottom plate of the head of an ordinary McKay wax-thread sewing-machine, on which I) is the needle-bar; b, the hooked needle; 0, the castoff point; d, the feedpoint; d, the feed-point block; 4, the tongue for the feed-block; e, the link for operating the feed-point, and f the stirrup, with its spring f, for drawing back the feed-point in the usual manner. 9 is the work supporting horn, as

0 usual, and It represents the presser-i'oot block secured in an adjustable manner by means of setscrew z to the vertically-adjustable pressure-foot rodk, as is common on McKay wax= thread sewing machines.

5 front grooved cam-plate secured to the presserfoot block h in the ordinary way.

Such parts as above described are well known in the art of wax-thread sewing-machines and form no part of my present invention, and are merely represented in the drawings to show .the welt that is used.

d represents the.

the class of sewing-machines to which my in vention relates.

To the lower end of the presser-foot block h is secured, by means of a set-screw, h, the shank l of the presserfoot Z, having on one side an interior groove, Z, and opposite to the latter the adjustable guideplate in, having an inwardlyprojeeting lip, m, as shown in Fig. 4:, such plate being adjustably secured to thepresser-foot Z by means of set-screws m m, passing throughslot-holes Z Z in the presserfoot Z and screwed into perforations in the guide-plate m, as shown. The groove Z and the guide-plate m, with its lip m, serve to receive the welt L and to guide it properly to the needle as it is being fed forward by the feed-point (1 during the operation of sewing the welt, upper or, and insole 0 together, as

represented in Fig. 4-.

Z is a slotted cut-away portion in the presserfoot Z, to enable the feed-point d to move freely backward previous to feeding the welt L forward without interfering or coming in contact with said presser-foot Z.

The guide-plate m is made adjustable to and from the groove Z, according to the width of Z is a lip on the under side of the presser-foot Z, such lip forming the under side of the welt-receivinggroove Z, as shown in Fig. 4:.

In sewing the welt to the shoe-upper n and insole 0 it is essential that there should be arranged on the presser-foot device an adj ustable upper guide, so as to properly guide the boot or shoe relative to the welt as it is being sewed, and for this purpose I locate below the plate at the upper guide 19, having a rearwardly-projecting bar, 1), that is pivoted to the under side of the presser-foot block h by means of a screw or pin, 19', passing through a perforation in the rear end of the bar pand screwed or otherwise secured to the presser-foot block h, as shown in Figs. 3 and 5. It is also essential that the upper-guide 19 should be capable of a lateral adjustment to and from the outer edge of the upper it during the operation of sewing the welt, owing to the peculiar curvatures at the shank portion as compared with other portions of the boot or shoe, and during such operation the welt must be guided nearer to the middle of the shoe at the shank part and farther out at the other parts of the shoe. ,Such adjustment in practice is about one-eighth of an inch, or a little more or less, according to the size or shape of the shoe. For this purpose I provide the bar 1) with an extension, p havingaslot-hole, 1), made through it, in which is located the eccentric cam or sleeve q, that is pivoted to the presserfoot block it by means of a pin or screw, q, passing through the eccentric cam or sleeve q and secured to the block h, as shown in Fig. 5. 'In one piece with the eccentric cam'or sleeve q is made a projection or handle, q, for the operator to take hold of or otherwise manipulate when he desires to change the position of the upper-guide 1) relative to the welt L.

Having thus fully described the nature, con-- struction, and operation of my invention, I wish to secure by Letters Patent, and claim- 1. The presser-foot Z, adjustably secured to block h, and having a groove to recelve the welt, combined with an upperguide, 19, arranged below the welt-guide, as and for the purpose set forth.

2. The block 71, having pivoted to it the upper-guidep, in combination with the slotted extension 1) the cam or eccentric q, pivoted at q, and provided with the handle or projec- Witnesses:
