EDGE SETTING AND INDENTING MACHINE.

Patented Jan. it), 1915.

Application filed January 10, 1914. Serial No. 811,470.

To all whom it may concern Be it known that I, ZOTIQUE BEAUDRY, a citizen of the United States, residing at Lynn, in the county of Essex and State of .Massachusetts, have invented new and useful Improvements in Edge Setting and Indenting Machines, of which the following is a specification.

This invention relates to a machine for setting and indenting the edges of the soles of boots and shoes.

The object of the invention is to provide a machine of the character set forth which will operate to set or burnish the edge of the sole of a boot "or shoe and at the same time will indent the upper edge portion of said sole.-

In the machine of this invention a rotary edge setting tool is employed for setting the edge of the sole and in combination therewith a rotary indenting tool is utilized for indenting the upper edge portion of said sole, the indenting tool being free to rotate relatively tothe edge setting tool so that while the edge setting tool is rapidly and positively rotated by suitable means, the indenting tool rotates only to the extent that it may be rotated by the movement of the edge of the sole of the shoe in contact therewith. Said indenting tool is preferably, al-

though not necessarily, arranged slightly eccentric to the edge setting tool and in its preferred form has a shank attached thereto which is adapted to rotate in an eccentric bearing provided in the shaft to which the edge setting tool is fastened, so that the indenting tool can rotate and also have imparted thereto a rapid movement trans versely of the shaft upon which it is mounted. Thus the indentations in the sole made by the indenting tool are rendered much more distinct and perfect, due to this transverse movement of the tool than would be the case if the indenting tool simply had a rotary motion imparted thereto. In other words, the corrugations of the indenting tool may. be given a movement transversely of the shaft upon which the tool is mounted, which results in a rubbing motion of the corrugations of the indenting tool longitudinally of said corrugations, and transversely of the sole ofthe shoe. it is also desirable, in some instances, to impart a reciprocatory motion to the indenting tool longitudinally of the shaft upon which it is mounted or laterally of the indenting tool itself and'of the sole against which the corrugations of the indenting tool bear, and my invention contemplates the employment of means whereby a lateral movement may be imparted to the indenting tool as well as a movement of said indenting tool trans versely of the sole or of the shaft upon which it is mounted.

While 1 have illustrated my invention as embodying an indenting tool which has means for imparting a movement thereto transversely of the sole and of the shaft upon which it is mounted, I do not wish to be understood as limiting my invention to this specific embodiment thereof, as the indenting tool may be mounted concentric with the edge setting tool without departing from the spirit of my invention. I believe it to be new, however, to combine a rotary edge setting tool with a rotary indenting tool, the rotary indenting tool being free to rotate relatively to the edge setting tool and the edge setting tool having means whereby the same may be positively and rapidly rotated.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a front elevation of a portion of an edge setting machine embodying my invention and having shown in connection therewith a portion of a shoe in section in position to be operated upon. Fig. 2 is a front elevation of the same. Fig. 3 is a sectional elevation taken on line 33 of Fig. 2. Fig. 4- is a detail section taken on line of Fig. 1. Fig. 5 is a front elevation of a modified form of my invention showing the same as applied to a different form of edge setting machine and showing a portion of a shoe in section in connection therewith and in position to be operated upon. 7

Like numerals refer to like parts through out the several views of the drawings.

In the drawings, referring to Figs. 1 to 4 inclusive, 10 is the frame of the machine in which is journaled a shaft 11. Said shaft is rotated by a pulley 12 driven by a belt 13 and rotates in suitable bearings 14: and 15 in the frame of the machine. A rotary edge setting tool 16 is fastened to one end of the shaft 11 and in the operation of the machine is rapidly rotated to burnish or set the edge of the sole of the shoe which is held thereagainst by the operator in a manner well-known to those skilled in this art.

The shaft 11 has a bore 17 therein which is eccentric thereto, and within this bore is rotatably mounted a spindle 18, to the outer end of which is fastened a rotary indenting tool 19, said indenting tool being held firmly on the spindle 18 by a screw 20' ing tool 19 is free to rotate independently of,

the shaft'll and in operationthe outer edge of the sole 24 of the shoe 25 is held in contact with the portion 26 of the edge setting tool 16, while the upper edge portion of the sole bears against the corrugations 23 on the indenting tool 19.

An arm 27 bears against the head of the screw 20 and prevents the indenting tool and its'spi-ndle from moving longitudinally of the shaft except to a slight extent, as, for example, where a slight difierence in thickness of thesole occurs,in' which case the arm 27 is capable of yielding slightly to allow for such variation, it being noted that the arm 27 is curved slightly and is somewhat resilient. The arm .27 is adjustably fastened by means of a set-screw 28 to a bracket 29 which is fastened to the frame 10 of the machine.

In order to hold the upper edge portion of the sole 24: firmly and still yieldingly against the corrugated portion of the indenting tool 19, a presser foot 30 is pro vided. This presser foot is adapted to slide upon astem 31 which is adjustably fastened by aset-screw 32 to a bracket 33 which, in

turn, is fastened to the frame of the machine. The distance to which the presser foot 30 can slide in one direction on-the stem-31 is limited by a shoulder 34 on said stem and in the opposite direction the dis tance to whichsaid presser foot can slide is limited by a collar 35 fast to said presser foot and adapted to abut against a stop 36 having screw threaded engagement with a pin 37 which is fastened to a collar 38, the

collar 38 being fastened to the stem 31 by a set-screw 39.

A spring 40,'under compression, is interposed between the collar 38 and the collar 35, thus tending to move the presser foot 7 at. all times towardthe shoe and to hold the collar35 again'st'the stop nut 36; WVhen properly set in relation to the other parts of the machine, the face ofthe presser foot 30 which bears against the tread of the sole should be in such a position that it will be necessary to compress the spring 40 and move the collar 35 away from the stop nut 36 when the sole of the shoe is placed in the position illustrated in Fig. 1 in readi ness to be operated upon by the machine.

The general o 'aeration of the mechanism hereinbefore described and illustrated in. Figs. 1 to 1 inclusive is .as follows: The operator holds the shoewith the outer edge of the sole bearing against'the portion 26 of the edge setting tool 16 and with the upper edge portion of the sole 24 hearing against the corrugations 23 on the beading. tool 1.9, said sole being held in this position firmly and yieldingly by the presser foot 30 with its coasting spring 40. The edge setting tool 16 rotated rapidly by the shaft 11 and burnishes or sets the edge of the sole while at the same time the operator turns the shoe into different positions to bring all of the portions of the edge of the fore part ofthe sole in contact with the periphery of therapidly rotating edge setting tool 16. While thus moving the sole into different positions the indenting 'tool will be rotated by frictionalv contact with the upper edge portion of the sole and at the same time a rapid movement will be imindenting tool, but a reciprocatory move- 7 ment transversely of sald shaftis also impartedlthereto, whereby a rubbing action takes place between the corrugations23 and the leather with which they are in contact, said rubbing movement being in a direction longitudinally of'said corrugations and transversely of said shaft and thus theflin-f dentations upon the upper edge of the sole are distinctly'and permanently produced.

In Fig. 5 a modified form ofmy invention is illustrated in which the invention is embodiedin' a machine wherein the shoe is held upon a jack and the edge setting mechanism is moved around the shoe, the frame of said machine being suspended in such aimanner as to allow the edge burnishing tool and the indenting tool to be moved backwardly andforwardly around the sole of the shoe while the shoe is supported upon a jack and tipped thereon to coact with the mechanism in enabling the edge burnishing tact with all portions of the edge of the fore part of the sole of the shoe.

Referring now to Fig. 5, a1 is the rotary edge setting tool and 4L2 the indenting tool, said indenting tool being mounted to rotate freely with a spindle 43 to which said indenting tool is fastened and which is eccentrically mounted within the shaft 50. The shaft is mounted in a suitable bearing 541- in the frame 4C6 of the machine and is rotated by means of a pulley 51. The spindle 4:3 is freeto move to a slight extent longi- -tudinally thereof in the shaft 50 and a longitudinal movement isimparted to said spindle L3 and the indenting tool 42 fast thereto by a collar 52 which has an inclined or cam-shaped surface thereon which bears against a similarly inclined on cam shaped surface 56 on the end of the shaft 50, so that as the shaft 50 is rotated a reciprocatory motion will be imparted to the spindle 4:3 and to the indenting tool 42, the spindle being moved toward the right (Fig. 5) by reason of the inclined surfaces 55 and 56 on the collar 52 and shaft 50 respectively and said spindle being moved toward the left when released by the rotation of the shaft 50 relatively to the collar 52 by the resilient nature of the leather which forms the sole 2% which, slightly expanding when released from extreme pressure, causes the indenting tool 42 to move toward the left as soon as the inclined surfaces 55 and 56 assume positions relatively to each other which allow of such movement. A. presser foot arm 14 is pivoted at 45 to the frame 46 and is held by a spring 47 under compression against the tread of the sole 24:. Said spring encircles a rod 18 fast tothe frame as and bears at one end thereof against a collar 49 adjustably fastened to the rod 48, while the other end of said spring bears against the arm 44, whereby said arm is held at its outer end against the tread of the sole of the shoe and thus presses the sole of the shoe against the corrugations of the indenting tool 42.

The operation of this embodiment of my invention is as follows; The shoe is placed upon a jack (not shown in the drawings, but well known to those skilled in the art) and the edge setting tool and indenting tool brought into contact with the edge of the sole 24. Then by a combined tipping of the shoe upon the jack and a swinging movement of the frame &6 the edge setting tool and indenting tool are carried around the edge of the fore part of the sole of the shoe and the sole is thoroughly burnished and indented. During this operation the indenting tool is rotated. It is also given a reciprocatory movement laterally thereof and a reciprocatory movement transversely of the spindle to which it is fastened.

While I have described the embodiment of my invention illustrated in Fig. 5 as applied to a machine in which a jack is employed, it is evident that this embodiment scribed may be used concentric with the edge setting tool, it may be'used eccentric to the edge setting tool or it may be given a movement longitudinally of the shaft to which the edge setting tool is fastened.
