INSEAM-TRIMMING MACHINE.

Be it known that We, FRANK H'. HAwKiNs and ADELono BOURGEOIS, citizensv of the. United States, both residing at Lynn, in thc county of Essex and State of Massachusetts, have linvented vcertain new and useful In'iprovements in' Insea1n"l`rimmin Mal chines; and `we do .hereby declare Athe follow- Aing 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 se thesa'me. 1 t

The present invention relates to inseam trimming machines and more particularly to that type ofinseam trimming machines in` whichthe trimming knife is cylindrical in shape. 'i The invention .is intended primarily as an improvement on `the inseam trimmingma chine disclosed in the' .atents to French and Meyer, No. 558,379, ated April 14, -189.6,

- No.` 590,831, dated September 28, 1807, and Selby, No, 788,796, dated May 2, 1905, but

is also applicable to other inseam trimming machines comprising a cylindrical trimming. knife. i l The machine disclosed inthe atents above referred to has been provide with a sole guide or rest extending outside 'of the knife as illustrated in thepatents to French and Meyer, or with a sole guide or rest arranred to extend inside of the knife as illustrated5 in The guides disclosed .in the patents to French and Meyer,` are 'of such construction thatfthey are necessarily v placed in themachine so as to bear upon the "the knife from cuttin sole ata considerable distance from the point [hat laced so sito bear upon the sole close tot einseam will'be ap `parent from an-.1ns`pect1 on of the patenty rawings.

closed in the patent to Selby engages the sole close to the inseam but inasmuch as .this guide extends inside 'of thel cutting edge of the knife, the shoe can be manipulated so as to bring the stitches' of the inseam into contact with the knife edgeand nearly as much care and experience is required on the part of the operator to properly trim a shoe as when the guides illustratedin the lpatents to French and Meyer are used. Furthermorethe guide disclosed in thev patent to- Sclbyleaves vthe cutting edge of the knife n exposed so that there is nothing to prevent ringing his hand into contact With the knife ed e.

`The object of the present invention is to provide anv improved sole guide for inseam trimming machines comprising a cylindrical which cuide can extend outside of the knife and at il knife on the inseam.,

seam. By makingthe guard inthe form of .a thin sheet, .the 'guard does not take up an objectionable amount of space between the shoe sole and theknife, so t at 'the guard can bear on the sole close to the inseam andstill permit the seam 'to be trimmed as close as may be desired. Inasi'nuch as :the guard ezt` tends'outside of the knife andlbears upon the sole "close to, the inseam, it acts in a Very eiiicientimanner tol guide the shoe and prevent 3 the shoe rombeiiig manipulated so as to cut curved in vthe direction of. t e cutting edge of f the inseam stitches.- 'The' uard also can be the knife to permit the shoe-to :be manipulated properly whether or not it is provided with a narrow shank. Preferably the guard is extended in the direction of the edge of the vknife and parallel thereto a sufficient distance to forni a protection for the hand of the operator. 'lhe guard may be supported in the machine iii any desired manner but preferably the support for the guard is located in front of the cutting edge of the knife, the support, when so located,l acting in an efficient manner to prevent the guard from being displaced by the shoe so as to dull the edge of the knife. Also the support for the guard preferably extends inside of and beyond the cutting edge of the knife so as to form a clearing device toremove chips or su ort with relation to the trimming knife.

ith the exception' of the guard, which constitutes the illustrated embodiment of the present invention, the parts of the machine illustrated in the drawings are constructed and arranged in the same manner as the corresponding parts of the machine disclosed in the patent to Selby, No. 7 88,796, 1 indicating the cylindrical trimming knife, 2 the crease guide, 3 the two-motion feed jaw, 4 the fourmotion feed aw, and 5 the uide which bears against the edge of the we t. The part 6, illustratedin the drawings, corresponds to the sole guide of the Selby machine, but this part, in the presen-t invention, instead ofv being utilized as a sole guide, forms a sup-.

port to which the guard of the present inventioii is secured.

In applying the present invention to the machine illustrated in the drawings, a guard 7 has beenprovided, which guard, as illustrated, consists of a thin sheet of metal extending from the support 6 outside of and beyond the cutting edge of the trimming knife. ,'lhis guard is arranged to bear upon the sole of a shoe inside of the inseam, as

illustrated in Fig. 3, and is curved in tlieudirection ofthe cutting edge of the knife'so that it permits the shoe to be manipulated in any desired manner. The curved shape of the guard is particularly advantageous when shoes provided with narrow Shanks are op- -erated upon, as the guard offers no obstruction to the untrimmed portion of the inseam at one side of the shank of the shoe while the other side of the shank is being trimmed.

As will be apparent from an inspection of lfigs. 2 and 3, the guard extends parallel to the edge of the knife a suiiicient distance to protect the hand of the operator while holding the shoe in position in the machine.

v-ihe guard is provided with a lateral projection, as clearly shown in Fig. 1, which bears against the outer face of the support G and the guard is secured to the support by means of a screw 8 passing upwardly through a poi'tioii of the guard extending at right angles to the lateral projection and screwing into the lower portion of the support. 'ljlie support 6 extends'inside of and beyond the cutting edge of the knife and is suiiiciently close to the knife to reinovechips or other obstructions from the knife. The

guard bears upon the support just in ad- Vance of the cutting edge of the knife so that the guard is prevented from being forced against the cutting edge of the knife by pressure exerted upon the shoe by the operator. I

The nature and scope of the present invention having been indicated, and the preferred form Lof the invention having been specilically described, what is claimed is z- 1. An'inseam trimming machine, having, in combination, a cylindrical trimming knife, means for 'guiding a shoe during the trimming operation comprising a guard consisting of a thin sheet extending outside of the knife in close proximity thereto and arranged tol bear` on the sole inside of the inseam and a support located in front of the knife from which' the guard projects over the edge of the knife.

2. An inseam trimming machine, having, in combination, a cylindrical trimming knife, means for guiding a shoe during the trimming operation comprising a guard consist-v ing of a thin sheet-extending outside of the knife in close proximity thereto, arranged to bear on the sole inside of the inseam and extending parallel to the edge of the knife a sutlicicntdistance to protect the hand of the operator and a sup ort located in front of the knife from whicii the guard projects over the edge of the knife.
