Specification of Letters Patent.

Patented Dee. 31,1912.

Application filed April 15, 1910. Serial No. 555,615.

To all erizo/m, it may concern.'

Be it known that I, filmini C. MEYER, a citizen of the United States, residing at Boston, in the county of Suffolk and State `of Massachusetts, have invented certain Improvements in Shoe-Sewing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

The present invention relates to an improved channeling device for outsole shoe sewing machines by which a' slot or groove of the desired shape and depth may be cut. in the tread surface of the sole in advance of the needle to receive the stitches.

The invention is designed primarily to form a slot o-r channel in the sol-e but it is to be understood that certain features of the invention may be embodied in a device or devices which remove a strip of leather from the sole to form a groove, and where in the claims'the term channel is used, it is to be understood that this term, unless otherwise qualified, designates any form of groove, incision or channel which may he cut in the sole to receive the stitches.

The objectsof the present invention are to provide, in an outsole shoe sewing machine, a channeling device which is simple and compact in construction, w'hich is efficient in operation, which is durable and free from liability to get out of order and which can-be 'adjusted vertically to'cut a 'channel of the desired depth, to provide an outsole shoe sewing machine with a channeling vdevice which can be adjusted verticall and which is securely held from lateral displacement, and to provide a sole sewing machine with a channeling device which will not interfere with the vproper manipulation of the shoe by the operator but which will tend to move the work into the machine into the proper position to receive the stitches.

With the above objects in view a feature of the present invention contemplates the provision in an outsole shoe sewing machine provided with a presser footl engaging the of a channeling be capable of `vertical adjustment yand in a position to out a channel inthe tread surface of the sole in advance of the needle to receive the stitches.

To hold the channeling knife securely against lateral displacement a feature ofy the invention contemplates mounting the channeling knife in a vertical guideway which guides lthe knife during its adjust ment and which holdsv it firmly against lateral. displacement. To adjust the knife vertically, an adjustable eccentric is preferably secured to the. presser foot and connected to the knife. Thisconstruction affords a simple and efficient means by which the knife can be easily and quickly adjusted with accuracy to cut a channel of the desired depth and constitutes a feature of the invention which is considered of value although it is to be understood that broadly considered any suitable means may be provided for permitting or causing a vertical adjustment of the knife on the presser foot. To cause the channeling knife to force the work inwardly into the correct position to receive the stitches, a feature of the invention consists in the provision of a channeling knife the outer lateral surface of which extends in the direction of feed and the inner lateral' surface of which extends at an angle to the direction of feed.

The several features of the present invention will be clearly understood from an inspection of the accompanying drawing in which- I Figure 1 is a view in side elevation of a portion of a well known form of outsole shoe sewing machine with the-preferred form of the present invention applied thereto. Fig. 2 1s a view in front elevation of the parts illustrated in Fig. 1. Fig. 3 is a view in side elevation on un enlarged scale of the presser foot and channeling knife. Fig. 4 is a detail sectional View taken on the line 4-4, Fig. 3', and Fig. 5 is a bot- 4tom plan'view of the presser foot and chan' neling knife.

As illustrated in the drawing, the invention is shown as applied to the outsole shoe sewing machine disclosed in-the patent to French '& Meyer, No. 473,870, 1 indi` eating the curved hook needle, 2 the needle guide, 3 the awl, 4 the work support and ,5 the presser foot. shoe is indicated in dottedlines witht-he outsole and welt between thel presser.' footl and work support, theoutsole of the shoe being indicated at 6 .and the welt at 7. 'As indicated in the drawing the work support engages the welt of the shoe while*` the In Fig. 1 a portion of aat,v

neling knife is made hexagonal in form so f in 15 tends to force the presser foot'is arranged. to bear against the tread surface jof the sole. p

In the illustrated embodiment ofthe in-v vention the channeling knife, indicated at 8, consists of al flat plate or bar secured at its upper end to the presser fdot and `provided at its lower end with a cutting blade 9 projecting below the lower surface `of the foot. Above the blade 9 the channeling knife is provided with a straight sided'pon tion 10 which is litted to slide in a vertical guideway formed in the presser foot, which guide'way holds the knife rigidly against outward lateral. displacement. The upper l portion of the channeling knife tits snugiy` against the side of the upper portion of the presser foot, as is clearly shown in- Figs. 2 and 3 and is secured to the presser foot by a clamping disk 11 and screw 12. To en-V able the knife to' be readily adjusted accurately so as to cut a channel of the desired depth, the disk 11 is provided with a cylindrical portion 13 arranged eccentric to the axis of the screw 12 and this eccentric portion is fitted into a corresponding hole in the upper end of the channeling knife. The portion of the disk ll overlapping the chaning, 1n combination, stitch formlng devices including a curved hook needle, a Work sup'- port arranged to engage the welt of ashoe, a presser foot arranged to engage the tread surface of the sole on both sides of the line of-the seam, land prov-idedwith a guideway and a channeling knife mounted on the presser foot so as to be capable of vertical adjustment in saidguideway and arranged to cut a channel in the tread surface of the sole in advance of the needle to receive the stitches.

2. Ain outsole shoe sewing machine, having, incombination, stitch forming' devices including` a curved hook needle, a work sup.- `port arranged to'engage the welt of a shoe, a presser foot arranged to engage the tread surface of the sole on both sides of the line ,of the seam, a channeling knife mounted to slide vertically in' a guideway in the presser foot and held against lateral displacement by said guide, and means for securing the channeling knife to4 the-presser foot, said knife being located in advance of the needle in position to cut a channel in the tread surface of the sole to receive the stitches.

3, An outsole shoe sewing machine, having, in combination, stitch forming devices including a curved' hook needle, a work supe 'port arranged to engage the welt of a shoe, al presser foot arranged to engage the tread 'surface of the sole on both sides of the line ofthe seamf the presser -in position toA cut a channel in the tread surface offthe sole .to receive the line of stitches, 'and aneccentric adjustably secured to the presser'foot and engaging the.channeling knife for adjusting the channeling knife vertically.. 4. An outsole shoe sewing machine, having, in combination, stitch forming devices including a needle, a work support arranged thatthe disk. may be readily turned about the axis of the screw 12 when the screw is loosened. Tig'htening of the screw 12 clamps the channeling knife between the overlapping -portion of the disk 11 andthe presser foot and securely holds the knife in adjusted position.

The knife blade 9 is located in advance` of the needle in positionto cut a channel in the tread surface of the sole to receive the line of stitches as will be apparent from an inspection of Figs. l and 2, Toobviate the tendency of the knife. to force the shoe outwardly so as to bring thelin'e of stitches too close to the edge of the shoe sole and lto assist the operator in keeping the shoe the proper position with relation to engage the welt of a shoe, a presser foot to the needle and other Vstitchl formi engaging the tread surface of the sole, and devices, the outer lateral surface of the a channeling knife mounted on thelpresser foot in advance 'of the needle in position to out a channel in the tread surface of the solefto receive the stitches, said knife having its outer lateral surface extending in the line of feed and its inner lateral surface eX- tending at an'angle to the directionof feed whereby the knife tends to force the sole inwardly over the work support.`

Intestimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
