simm rs, a

citizen of the United ZS tates," residing at I Beverly, in the county of Essexand State of Massachusetts, have invented certain linprovements 1n Shoemakmg-Machmes, of

which the following description, in connect on wlth the accompanying draw1ngs,1s a *speclfication, l ke reference characters on the drawings indicatingilikelpartsin the several figures. l 3 I l v.

This inventionrelates to machines for operating uponboots and shoes, and is herein shown and described, byway of example, as

embodied in Il'lZlChlIleSffOI" removing the sur plus material from the forward face'of the heels of boots and lshoes .in vthe operation knownas breasting. l In the process of making boots and shoes, it ,is: customary, aftenfthe shoe has been lasted and theoutsole.attachedfiand rough rounded, to nail-on the heel in the rough condition with nailswhich are allowed to project somewhat from the outer face of the roughheel. A"carefuilly shaped top lift is then spanked uponpthe projecting nails and servesas a guide to indicate thedepth of cut I tobe removed by the rotary cutter'bywhich the convex'portion of theheel is trimmed. The surplus material onthe front or breast face s removed in a separate operation which is usuall y performed by a-reciprocating breasting knife which may bereither flat, for breasting thelheel straight, or

' moved. It is, moreover,commonpractice to gouge-shaped, so arranged as to render the the top lift is usually straight, however, this could be done only in the case of a flat knife. If a straight-edged toplift is used on heels which are to be breasted with acurved or gouge-shaped knife, only the corners serve as position indicating means forthejknife a'ndan intermediatepart of the lift is rebreast heels with the planeof the breast faceiat anangle, of a1 few degreesto the longitudinal median line of the heel,ithe inthetop lift andlindicate the position of the heel relatively to the knife the heel at the limiting the amount swing of a right is always equal and oppositeto that of a 'Iatented Dec; 1, 1914;. 'seriainaeeaws. 7' i shoesandin the other direction for left Shoes. ,In'this practice it will be apparent thatonly the right or the left corner of the top lift can be used as a guideand that this corner indicates merely the forward limiting position of the plane ofthe breasting cut. It 1s desirable, therefore, in the operation of breasting heels" rights and lefts, z. e. as last above described, to use agage which will" contact. with the breast edge of proper angular for securing the proper angle at the breast tothe medianline for either rights or lefts.

It, is theobject of this invention to provide an improved gage for this purpose WlllCll may be conveniently arranged upon the breastingmachine and will enable the operator easily and accurately to position ing knife. An important feature of my invention is the provision'of animproved breasting gage arranged for oscillation about an axis approximately perpendicular to the tread face of the heel and provided with stops for of oscillation to equal angles upon opposite sides of a line parallel to the edge of the knife.

It is also a notable feature of the invention that the'stops for limiting the pivotal movementof the gage are equally and oppositely adjustable simultaneously so that the heel relatively to the knife left heel.

Breasting machinesof the-type to which my invention is particularly adapted for. application are provided with a presser plate which is pressed against the tread, face of the heel to clamp it in p, sition prior to the cutting stroke of the knife.

As a feature of my inventionthe gage is so mounted as to be maintainedin constant clination being in" oneidirection a; right proper angle to the breastvertical, relation; to the presser plate and hence in proper positionto engage the breast face of atop lift pressed against the'plate. This result is attained by pivoting the arm carrying the gage at apointin lateral alinementl.with .the forepart of the shoe and providing means for resiliently swinging the armtowardthe presserfplate, a stop heing provided on the arm for contact a with means attached to the plate to limit the By mounting the gage carrying arm as above indicated, it may be moved toward the shoe against the resilient means tending to move it against the presser plate, and it is a feature of my invention that the arm.

is arranged to be engaged by the hunter of the breasting machine and moved down against the shoe shank. movement, however, the breast gage must bedrawnaway from the heel breast after having performed its positioning function, in order to clear the surplus material about to be removed from the breast face of the heel. Incidentally, also, this movement draws the gage away from the path of the breasting knife. The feature of having the hunter engage the arm and force that against the shoe instead of coming directly in contact with the shoe itself is of importance for the reason that as the arm presents a larger area for contact with the shank than does the hunter, there is less danger of the shank being marred by the action of the hunter in arresting the movement of the knife.

As a further feature of the invention, the support of the gage carrying arm is arranged for adjustment in a direction at right angles to the plane of the knife and hence the position of the gage relatively to the knife may be adjusted to determine the amount of material to be removed from the heel, and, further, the gage carrying arm is arranged to be swung into inoperative position at the will of the operator, so that the machine may be used without the gage if desired.

Referring now to the drawings which represent a machine provided with an illustrative embodiment of my invention; Figure 1 is aside View of the operative portion of the machine; Fig. 2 is a perspective view of the same; Fig. 3 is a sectional view, partly in plan, taken on the line 3-3 of Fig. 1.

Referring particularly to Fig. 1', the operative parts of the niachlne are supported upon a standardor column2 and comprise of the" knife is forced against the back plate 20. while the forward plate 14 is forced against the inner faces of the cheek members 12 and the-knife is thus firmly clamped in place.

To permit this To furnish an abutment forthe knife an overhanging portion 24 of the knifecarrier has screws 26 'threadedtherethrough and so located that they engage the upper end of the shank of the knife. Lock'nuts 28 are provided to hold the screws 26' in adjusted position. The knife slide'4 is actuated in the usual manner, means beingsetinto operation by a treadle to reciprocate the ac-' tuating slide 6, which is connected with'the knife slide, to reciprocate the knife toper-- form-the breastingoperation." I

It is necessary that the cuttingaction of the knife be arrested when the, shank port1on of theshoe is reached and animal stop mechanism is provided for disconnecting the knife slide fromjthe actuating slide at the proper moment inthe knife stroke. This is effected by the contact of the bunterBO' with the shoe shank, :1 the hunter acting through the lever 32 to actuate mechanism for disconnecting the knife slide from the actuatins slide.

The machine is" provided with the usual presser plate 40 wliich"is*arranged to be.

wardly and acts through the spring 44 to resiliently depress the ,presser plate against the tread face of thevheel. In order con- 1 veniently to limit the range ofrnovement of the presser plateupwardly, a bracket 52 is attached to the machine frame and arranged to project inwardly over the lever 46 and a screw 54 is threaded through the bracket into engagement with the lever 46. By art justing the screw 54 the upper'limit of movement of the p'resser plate .may be a changed.

lower end of the slide 50 upon the pin 56 and is held in its normal substantially hori- The presser platel40 is pivotedtothe zontal position by means of a spring 58 at tached to theplate at a point forward of thepivot 56 and connected to ahandle 60 by which the toggle links connecting the lever 56 withthe slide 50 are operated. The

spring therefore acts to 'hold' the presser plate up in its operative position and to hold the toggle lever 60 down with the toggles in a straightened position. By raising the lever 60 and breaking the toggle connecting the slide 50 with its operating lever the press'er plate may be movedupwardly to a position behind the knife and the plate may then be conveniently adjusted longitudinally by positioning it against the back of the knife and clamping it.v Upon releaseof the lever the plate drops back into its normal position beneath the knife, andfthe toggle being held straight by the weight of the slide-50 and by thespring 58, the plate may be actuated-by power transmitted from thelever 4.6 through the toggle. I r

The slide v50is mounted forvertical reciprocatio'n in ways formedin abracket--62 on the frame of. the machine. Extending rearwardly from the slide 50 is a projection 64 and a curved abutment 66, the function of which'wi'll appear later, is secured pivotally to the pin 56 and is attached to the projection 6% bymeans of an eccentric pin 68 by rotation of which the vertical position of the forward end of the abutment may be adjusted, as will be readily understood.

The mechanism for locating the position of the heel of f the shoe relatively to the breasting knife, which forms an important feature of the present invention, comprises a gage 90 which is supported by a casting 70 rigidly secured to the top of the machine frame. Av hanger'72 is mounted for sliding movementin 'a horizontal direction upon the casting 7 0 and-is normally "adjustablymaim tained in theinward position of its movement" by a spring 74with' a limiting stop screw 7 6 carried thereby in contact with the casting and fixing the inner limit of its movement. -To reciprocate the hanger 72 so as to remove the heel locating device from contact with the rough portion of the heel to be-removedby the breasting operation, as well as to remove it from the path of the knife, a roll 78 is mounted. on the upper portion of the hanger 72 in the path of a member 80 secured at 82 to the knife slide. and having the cam surface 84 for contact with the roll 78. As the knife slide descends the cam surface .84 engages therOllTS and forces the hanger 7 2 outwardly against thetension of thespring 74, thereby carrying the heel locating device mounted upon the hanger *(2 out of thepathof theknife.

-Means is provided for holdingthegage in retracted position, when desired, and as shown this .means comprises a pawl, -.73 which is normally held by gravity in position to engage suitably arranged teeth 71 formed on the upper face: of the hanger 72. lYhen the gage is withdrawn from operative position, the .pawl, 73,vwhen in the position shown, will engage the teeth 71 and I hold the gage out of the wayuntilit: is desired to 7 use it again. lVhen thegage is desired,the

pawl 73 is raised by the handle and thrown backward against aiportion of the machine, and 'the gage is permitted to resume its operative position under-the im pulsion of the spring 74. I "Theheel locating devicercomprises a gage member 90 which, as shown, is adapted to contact throughout the fulllateralextent of the breast edge of the top lift. and :is preferably so' thin thatitengages the top .lift only the member 120. I

ofthe heel. The member 90 is pivoted at 92 to an'inwardly projectingvportion '95 of an arm 94 and the otherend of the member 90 is formed to engage alternatively the limiting stops 96, 97, which are "slidingly mounttions in the inclination of theheel breasts of right and left hand shoesto the longitudinal median line of the heel. .The vertical position of the gage 9O relatively to the presser plate 40 is determined by the abutment 66, already referred to, with which a block 102secured at104 (Fig. 3) to the arm 9-1 normally contacts. The vertical position of the gage 90 relatively to the presser plate may beiadjusted by means of the eccentric pin 68, it being desirable to locate the upper face of the gage 90 just below the lower face of the presser plate .40. The arm 94: is provided with an inwardly projecting portion 106 formedto interlock at 108 with a member 110 pivoted at 112 and guided-for movement about said pivot by lugs 114 arsliding movement in a bearingin the lower end of the hanger 72. Ascrew 124: having an operating head:126 is held from longitudinal movement in the lower end hanger 72 by the cap plate128 and at its inner end isthreadedinto the stem 122 of By operating the head 126 it will be seen that the breast gage 90, together with the arm 94: and connected parts, may be moved horizontally and the breast gage 90 thereby adjustedtoward and from the heel to vary the amo unt of material removed from the breast end thereof. The block 102 is normally held resiliently against the abutment 66 and" to effect this the member 110, F ig. l, is provided with "a stem 130 extending "through'an opening in the hanger 72 and having thereon a compression spring 132 abutting at one end against a collar 134 on the hanger and at the other against a collar 136, secured-upon the outer end. of thestem 130. It will .be seen that the spring tends to turn and hold the upper end of the member 110 outwardly about the pivot 112 and that the arm :94 being normally: rigid with the member 110 is thereby held upwardly againstthe abutment 66. j i The shoe to be operated upon is placed upon the ack 140 with the .toe portion resting; upon the toe rest 142. The treadle referred to. is. now depressedto lower the of the 'presser plate against'the tread face'ofthe heel During this movement of the presser plate the abutment 66 is of course carried down and by contact with the block 102 swings the arm 9% about the pivot 112, com pressing the spring 132. When the presser plate has reached contacting position with the tread face of the heel, the breast gage 90 will befin position just in. front of the breast. edge of the top lift. The shoe is now drawn forwardly, bringing thebreast edge of the top lift into continuous engage-i ment with the gage 90 and the shoe is then swung to right or left, as the case may be, while still maintaining its continuous engagement until the outer end of the gage member 90 contacts with one or the other of the members 96 or 97, according as a right or left heel is being breasted. The

shoe is now definitely positioned relatively to the knife, and upon further depression of the treadlc the clutch is thrown in and the knife actuated to perform the breasting out. As the knife slide starts upon its downward movement the cam 80 contacts with the roll 7 8 and thehanger 7 2 is forced outwardly, carrying with it the gage 90 and connected mechanism. "The gage 90 is thus drawn out of the way of the material of the heel which is .to be removed by the breasting cut of the knife and also out of line with the cutting edge of the knife. As the knife descends farther, the hunter 30 comes into contact with the inwardly projecting portion 95 of the arm 94 and communicates its downward movement thereto, further compressing the spring 132 until finally the portion 95 contacts with the shank portion of the shoe and further movement of the hunter 30 is arrested. As the movement of the hunter stops, the arm 32 is moved relatively upward, and the mechanism for dis connecting the knife slide .L from the actuating slide 6 is operated,v and further outting action of the .knife prevented; it being understood, of course, that the stop 30 has been so adjusted that the knife will cut down to but not into the shank portion of the sole.

It may-be desirable at times to swing the arm 94 out of its operative position and for this purpose the interlocking engagement at 1080f the portions 106 and 110 is provided. By drawing the portion 106 outwardly against a suitably arranged spring, not shown, it is drawn out of interlocking engagement with the part 110 and may then be swung downwardly upon the axis of the portion 106 into'an inoperative position.
