To all whom tt may concern:

Be it known that. 1, ANDREW Errnun, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in "Welt-Guides for Shoe-Sewing Machines; and I do here by 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 appertains to make and use the same.

The

guides or shoe sewing machines.

Sewing machines especially designed for attaching the welt to the upper and insole of it lasted bootor shoe are commonly provided with a guiding device for properly positioning the Welt with respect to the upper and insole and to the sewing instru- 'mentalities, and particularly with respectto the needle, so that the letter shall invuriebl enter the groove which is usually formed in the surface of the welt. I-leretofore it has been the practice to construct suoh guiding devices, with the Welt receiving; aperturo oi fixed and definite depth and suiiiciently large to receive the thickest welt it may be desired to sow noon the nuiehiiue. lt hen, however, Welt lose tluolmeee it; one

ployed, the device becomes uncertain in up aeration and may fail to position the welt ,iroperly.

It is the object of the present invention to '35 avoid these defects in rim: tlGiitfliS and to provide it welt guide tor sewing machines of the above described type which may guide and position, with certainty and accuracy Wclts 0t ditterent thielu' ess.

40 With these objects in view ti 3, present invention consists in the welt guiiflc herein-- after described and. claimed.

in i the uorouipunying drawings wliiei'i illustrate the preferred iuubodii'nent oi the present invention, Figure .t a top phi-n. view of the guide eoniple c; t le. 2 is at side elevation of the some, looking in the direction in which the welt travels; llig. 23 i5 :1 bottom plan view; Fig. i u. front t5l8t'ittion; Fig. 5 is a, vertical section on line ti e of Fig. 1 looking toward the right; Fig. ('3 is at bottom plan view of the body Portion of the guide with the adjustable guide ieeos oresent invention relates to welt .boi-iion by the set serew removed; Fig. 7 is n "-JQiiIiCZ-ii section on line 7-7, Fig. l.

As shown in the d awings, the main or body portion 1 of tin weit guide torn'iing the subject of the presentinvention is suit stantially horizontal and is provided it its rear end with vertical ear or h1g2; 2 l to the apertures 3 to re the screws or other devices for attaching the welt guide to its supporting lover or slide. The front end oi the body portion 1 provided with a notch or recess i (see Fig. it) through which the curved needle of the sewing nuiohine pass in its movement toward and from the work. The bottom of the body portion is formed with u. welt guiding surfaceiii, the trout part of which is curved and the rear part struight, as shown in Fig. i. This ,guie'ling portion 5 forms tin upper wall of the weit receiving aperture b of the guide, one of the side wuils and the bottom well being; termed by a sheet metal guide piece semi-ed lie the to body portion of the guide. As shown in Q and i, thie sheet metal piece has two puruiiel end portions 7 and t3, the to root of, which eou.- -;iitute:i one of the side wnllu, us it were, of the writ receiving; 12;" i
