T 0 all whom it may concern:

Be it known that I, \VILLIAM H. BORDEN, a citizen of the United States, residing at Winchester, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Machines for Use 1n the Manufacture of Boots and Shoes, of wh ch 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.

This invention relates to machines for operating upon the soles of boots and shoes, and particularly to a machine for trimming a sole while it is being attached.

In the manufacture of the better grades of shoes, such, for example, as Goodyear welt shoes, it is customary to employ outsoles which have not been brought to approx mately their final shape before being laid upon the shoe. The reasons for this practice will be apparent when the nature of the earlier steps in the manufacture of a shoe of this type is considered. In order that the operations following the sole laying operation may be performed conveniently it is practically essential, in manufacturing shoes in which soles of the type above re ferred to are employed, to perform what are usually termed rough rounding operations. There are usually two of these rough rounding operations, one for bringing the forepart of the sole into approximately its final outline, and the other for bringing the heel seat end of the sole into approximately its final outline. According to the usual practice the forepart of the sole isrough rounded and attached to the welt before the heel seat end of the sole is attached, the attachment of the heel seat end of the sole to the insole, or to the insole and upper. being usually effected by means of metallic fastenings. According to the present practice the rough rounding of this end of the sole may take place either before or after the attaching operation. Probably the most usual-practice is to attach the heel seat end of the sole and then to rough round it with a rotary cutter. Another practice is to round the heel seat end of the sole by a cutter shaped to fit against and to be guided by the counter of the shoe in advance of the attaching operation. It will be noted. however, that by either practice the heel seat 7 rough rounding operation is a separate step in the manufacture of the shoe and that, furthermore, when the rotary cutter is employed the material trimmed oif is of no further use. At a later stage in the manufacture of the shoe the sole edge trimming operation. which brings the sole to its final outline, takes place.

The present invention aims to do away with the separate heel seat rough rounding step in the manufacture of shoes and also to elfect the cutting in such a manner that the material trimmed 01f may be utilized for other purposes. \Vith this end in view the invention aims to provide a machine in which the rough rounding operation may be performed simultaneously with, or as a part of,- some other operation upon the shoe and preferably with some other operation upon the sole.

The invention aims further so to combine sole trimming means with other means for operating upon the shoe that the usual functions of the other means will not be interfered with by the trimming operation and that additional work will not be imposed upon said means in the performance of said functions.

In the preferred embodiment of the invention, the heel seat rough rounding operation will be performed during the attachment of the heel seat.. Preferably the cutting of the sole will be eli'ected in a step y step manner so that it may bear a proper relation to the row of successively inserted fastenings with which the heel seat is usually attached. Furthermore the cutting will preferably bear a determined relation to the feeding of the work and will preferably be along the line of feed.

In one important aspect therefore the invention may be said to comprise the combinatio n with means for successively inserting fasteninginto orkfed past said means of riieans 1e w gKih aste'ihv sWtmwngiheline of the ivy ed. Preferably the tri nming opera 1011 will take lace af te1; the work has been fe. referably made for Q .C ilI.against the ns which will action preferably move along the work. Preferably the direction of movement. of the trimming means as it moves to trim the work" will be opposed to that in which the work is fed. this arrangement permitting the more convenient employment of work feeding means. particularly the ordinary type of work feeding means in which the awl which forms the fastening receiving opening in the work is employed to feed the work. This arrangement also insures continuity of the trimming. that is. continuity of the successive cuts. and permits the trimming to conform more closely to the desired final outline.

In another aspect. therefore. the invention may be said to comprise means for successively inserting fastenings into work fed past said means. of means for trimming the work after each feeding step. preferably operating along the work in a direction opposed to that in which the work is fed.

'hen looked upon as an improvement in trimming mechanism the invention. in one aspect, may be said to comprise means for feeding the work and means for trimming the work movable along the line of the work feed. Or. when combined. for example. with means for clamping the work atthe end of a feeding step. the invention. in another aspect, may be said to comprise, in a trimming machine in which provision is made for holding the work stationary after a feeding step, means for eifecting a stepwise trimming of the work operating while the work is held stationary.

In the preferred embodiment of the in vention the trimming means has an inoperative movement during the operative movement of the feeding means or during the feeding operation, and an operative movement during the inoperative movement of the feeding means or after the work has been fed, and this timing and the arrangement by which it is brought about constitute important features of the invention. It will be noted that when feeding means is provided,- this timing permits the convenient actuation of the trimming means by mechanism constituting a part of. or associated with, that which actuates the feeding means.

Preferably the inoperative movement of the trimming means is greater and faster than the operative movement of the feeding means whereby the trimming means may be withdrawn from its previous cut to permit free turning of the work during the feeding operation and to prevent damage to the trimming means by such turning. This arrangement contributes much to the practicability of the combination of trimming means with a. machine of the type herein illustrated and constitutes an important feature of the invention.

To insure'proper gaging of the trimming,

the gaging means is preferably movable, with the trimming means and in the preferred embodiment of the invention in which the trimming takes place after a work feeding operation the gage is preferably movable with the work as the work is fed.

In some classes of work it is desira le not only that the edge of the sole be rough rounded. but also that the trimming or randing of the upper edge of the sole e started. Provision has therefore een made in the present invention for eli'erting a randing of the sole as the edge of the ole is trimmed. and an important feature of the invention is the novel means; for [llls purpose. It will be apparent that the l l()\'l. i ll of this means in a machine having some or all of the different features liereiualovc pointed out presents many novel and u.-cful combinations. To these various combinations attention will not be directed ln'i'c in detail. but it is my intention to make them the subject-matter of several of the claims.

It will be noted that in the preferred cmbodiment of the invention advantage has been taken of the movement and positi n of the gaging means. hei'einabove referred to. to provide simple and effective means for supporting and actuating the rand trimming means and to the novel combina tions involved in this arrangement attention will be especially directed in the ap pended claims.

()therimportant features of the invention and new and useful combinations of elements will be set forth in the following description and claims. and the purpose and nature of the invention will be more fully understood when the description and claim are read in connection with the accom mnving drawings illustrating a preferred cinbodiment of the invention.

Fig. is a side elevation of a portion of the machine, illustrating especially the mechanism for clamping and releasing the work.

The fastening inserting machine with which the invention is herein shown as asociated or in which it embodied is of the type illustrated in the patent to Louis Goddn. No. lQOAS'Z-L, Jan. 2%. 1893, and is known to the trade as the "loose nailing machine For a detailed description of the parts of this machine herein illustrated but not specifically described reference may be had to the said patent, and so far as the parts of said machine are herein described such description will be made by reference to parts of the drawing lettered as in the said patent.

The machine has a head mounted upon a column or standard A in which are bearings for the main driving shaft C". The various cams through which operative movements are imparted to the different mechanisms in proper timed relation to each other are carried by the main shaft C At the front of the machine is a swinging head or frame B in which reciprocate in a vertical plane the driver bar a carrying the driver a and the awl bar f carrying the awl f. The head is swung when the awl is in the work to feed the work and the mechanism for swinging the head comprises a rockshaft D mounted in bearings D and B, said rock-shaft being rocked by an arm D clamped upon it and carrying at its outer end a cam roll traveling in a cam groove in the cam disk D upon the main shaft C'-. At its forward end the rock-shaft carries an arm D connected to the head 13 in the manner described in said patent whereby said head is swung to feed the work. All of the parts thus far described. with the exception of the arm D. may be substantially those disclosed in said patentand such as are in common use.

The trimming mechanism, which may conveniently be formed as an attachment to be put upon the. commercial loose nailing machine or other fastening inserting machine for trimming heel seats while they are being nailed. comprises, in a referred embodiment, a bracket 2 bolted to the column A or to a clamp member 3 of a clamp surrounding said column, said bracket having lateral curved ways i and 6 for a carriage 8 carrying the trimming knives and the gage or guide. The carriage is reeiprocated to ititl lei/aliases COPY 3 cause the trimming knife or knives to effect the trimming operation by means of suitable connections with the driving shaft of the machine. the connections herein shown comprising an extension 10 of the rock arm 1 below the rock-shaft D". the arm 10 bein; connected by the link 12 to a lever arm it pivoted at 16 upon an ear l5 formed upon the bracket 2.

At its end remote from the pivot l the lever 1 is connected by a link '1'. to the carriage The ways and (3 are curved in concentric arcs in order that the trimming knife in its trimming movement may more in a curved path. thereby approximating the desired contour of the work to be trimmed. Preferably two trimming knives are provided. one for trimming the edge of the sole and the other for randing its upper face. although the latter knife may be dispensed with on some kinds of work. The edge trimming knife is herein shown as. having an upstanding sharpened blade portion 2% and a rearwardly extending stem portion 26. preferably dove-tailed in shape. and adjustably confined in a dove-tailed groove in a holder 2% by the clamping plate 30.

The normal position of the edge trimming knife is illustrated in Figs. 1. l, l and o. [n this position the knife is adapted to trimthe work in a line substantially parallel with the line of feed. When the knife is to operate upon a blocked sole. for example. which projects considerably in the region of the shank whereby it is necessary to cut in from the side in order to bring the knife into the desired relation to the upper for the succeeding trimming steps. it is desirable that provision be made for moving the knife automatically into the desired relation to the upper. and a feature of the invention is the provision of means for effecting ll1'll a movement of the knife. To this end the knife holder is preferably so constructed and arranged that it may be adjusted to cause the knife to make a first cut at an angle to the line which it will follow in the succeeding trimming steps. To permit such adjustment the knife holder is preferably carried upon a segment 32 pivoted at 13L upon the carriage b. said segment being provided with teeth 36 which mesh with teeth 38 upon a segment lever 1L0 pivoted at l'. on the carriage S.

The lever to has a rearwardly e.\"tendin arm A- arranged to engage an adjustable stop to upon the bracket :2 when the carriage S is moved from right to left. Figs. 5 and 6, during the work feeding movement of the awl, and thereby to cause the segment 32 to be turned in a counter-clockwise direction about its pivot. This turning movement of the segment 32 serves to restore the knife 2i to its normal position after it has been turned into the position shown in Fig. I). and as it is thus restored to its normal osition to cause it to cut in from the edge of the work in ad ance of its .irst trimming movement.

A spring -5 normally tensioned and connected at one end to a stud 50 on the arm ll and at its other end to a stud 32 on the carriage tends to draw the arm it into contact with the stop to. The normal position of the knife 24 is determined by an adjustable stop 5% carried by a lag 3o upon the carriage 8.

To keep the segment 32 from turning during the trimming operation means is preferably provided for locking it in normal position. The illustrated means comprises a spring-pressed bolt 58 arranged to enter a notch 60 in the side of the segment 32 when said segment is in normal position. said bolt having on its under side a shoulder 62 (see Fig. ti arranged to be engaged by a push pin (i-l provided with a thumb piece 66 whereby the operator may push the bolt 58 out of engagement with the notch 60. thus permitting the segment 32 to be turned into the position shown in Fig. 5 by the action of the spring :8 upon the arm H.

Before the trimming operation begins. that is when the carriage moves from right to left in Fig. 5 or Fig. 6. as the work is fed to bring the first awl hole 68 beneath the driver a the arm H will engage the stop 46 and the knife 2t and its holder 28 will be turned about the pivot S-l. thus causing the knife to cut into the edge of the work and come into its normal position in advance of the return movement of the carriage 8 when the knife will make a cut substantially parallel with the line of feed of the work.

The actuating connections, including the lever ll, are preferably so proportioned that the inoperative movement of the trimming knife 2t is greater than the work feeding movement of the awl in order that the knife may be drawn back from the closed end of its cut to permit the work to be turned freely without danger of breaking the knife. To permit adjustment of the movement of the carriage 8 to accommodate it to different lengths of work feed, the lever H is preferably provided with a series of holes T0 into which fits the post carrying the ears 72.

To permit the initial adjustment of the carriage 8 and knife 2% the link 12 is preferably made in two parts comprising a clamping sleeve 121 pivotally connected to the arm 10 and a member 122 having a stem extending into the sleeve 121, said member 122 being pivoted between the ears T2.

The gage which determines the location of the row of nails with respect to the edge of the work and also the amount of material to be trimmed from the edge is shown at 74, and as herein illustrated is shaped to en- BEST AVAlLABLE COPY gage the counter in the region of the rand crease. The gage it is adjustably connected to the gage carrier 76 by a set screw T8 passing through a horizontal slot in the carrier 76 whereby said gage may be both angularly and bodily adjusted on said carrier. The carrier 76 is pivotally mounted upon the carriage 3 between upstanding ears R0 and normally held in its uppermost position by a spring The uppermost position of the gage T4; is yieldingly determined by a second spring 8 bearing against the under side of its rear'end whereby upward movement of the gage with the work beyond its normal position is permitted. Preferably means is provided for varying the tension of the spring 8% in order to vary the normal position of the gage Tl. The part of the gage which contacts with the upper is preferablv made of brass as it has been found that this does not rub the upper as much as some other metals.

To prevent the trimming from riding up over the upper end of the knife 2% a groove 86 is preferably provided in the under side of the guard plate 88 in which said u pe'r end of the knife travels. For convenience in adjusting the knife this groove is preferably formed by making the guard plate in two parts, 881 and 88-2, the part 1 being preferably stationary and the part 2 having a stem 90 provided with slots through which pass set screws 92 whereby said part may be adjusted to adapt it to ditl'erent positions of the knife 24.

With the mechanism thus far described the edge of the sole may be trimmed. it is. however. frequently desirable to rand the upper face of the sole somewhat to permit the rotary rand trimmer used in the finishing operation more readily to enter the rand crease. In the illustrated construction novel means for effecting this randing operati n is provided. Advantage is taken of the fact that the gage Tl travels with the work dun ing the work feeding operation to mount the rand trimming cutter upon said gage so that as the ga e returns to its initial position it will effect a randing of the work. lret" erably this rand trimming cutter will operate in advance of the edge trimming cutter. and in the illustrated construction the rand trimming cutter is shaped to cut a groove or channel in the upper face of the sole in such position that the edge trimming cutter will travel approximately through the middle of said groove or channel. therebv leaving a beveled or randed edge upon the trimmed part of the sole. The rand trimming knife or cutter is shown at t and is mounted upon the upper side of the gage Tl. said gage being cut away somewhat beneath the arched cutter blade 9 to provide a passage for trimmings. The stem 96 of the cutter 9* is provided with slots through which the attaching screws 8 pass. whereby adiustment of the cutter transverselv to the line of feed of the work is permitted. The utting edge of the cutter 4 is upon the right-hand side as the cutter is viewed in F g 5 and 6.

The operation of the machine may he l'rietlv rw-apitulated as follows: The shoe. upon which the sole to e nailed and rough rounded has been laid. is placed upon the work support. which may he the jack 100 shown in Fig. 1. and the machine is then started; If the sole is a blocked sole. for example. and the shank of the shoe is considera ly narrower than the shank of the sole. the operator. before he starts the ma chine. will press in the push pin 6% by means of the thumb piece 66. thereby moving the bolt 58 out of the notch 60. thus permitting the segment 32 to be turned into the position shown in Fig. 5 by the action of the spring 4 upon the arm H of the segment lever 40. The knife '24 will thus be moved into a position such that when the carriage moves toward the left in Figs. 3 and 6. as the awl moves to feed the work. the knife will cut in from the edge of the sole. as shown in Fig. 6. and thus come into position to effect the proper trimming cut upon the movement of the carriage toward the right in these figures. as the awl returns to initial position. As hereinabove pointed out. the movement of the knife into its normal trimming position is efl'ected by the engagement of the arm H of the segment lever *0 with the stop 46 upon the bracket.

In Fig. 6 the work is shown after the first awl hole 63 has been made. and the work has een fed into position to receive the first nail or other fastening. The cut illustrated in this figure has been made by two movements of the knife '24. one movement being about the pivot 34 by which the knife has cut in from the edge and come into its normal cutting position. and the second movement being in an are having a center common with the arc of the path to travel of the carriage S. the first movement. as above indicated. taking place when the carriage moves toward the left in Figs. 5 and 6 as the awl feeds the work. and the second movement taking place when the carriage moves toward the right as the awl returns to its initial position. After these two movements are completed the fastening inserting operation takes place. It will thus be seen that the centers of the two movements of the knife 24 are upon 0 posite sides of the line of cut. When the knife has come into the position illustrated in Fig. 6 the bolt 58 enters the notch 60 and the knife is locked in this position. so that succeeding cuts lie in arm having a center common with the center of the arc of the path of travel of the carriage 8. The shoe is pressed againstthe gage 74,

BEST AVAILABLE COPY a the upper bearing against the side of the gage and the sole projecting over the upper face. When the jack 100 is raised under the action of the usual spring provided in the machine disclosed in the patent above referred to to cause the sole to be clamped against the guard plate '58. the gage 74 will travel up with the shoe and sole under the action of the spring 8'2 antl also under the action of the shoe. since the gage is so shaped that it tends to enter somewhat the rand crease between the sole and the upper. The rand trimming cutter 4 will thus e brought into operative relation to what will be the upper face of the sole in the finished shoe. and as the gage T4 moves with the carriage 3 the glitter 9* will cut a groove in this face of the sole upon the return movement of the carriage after the work has been fed. This groove will be split by the knife '24 which follows the cutter 94 so that part of the groove will be left upon the trimmed sole and the other part will be upon the trimming which is removed. After the nailing has proceeded around to a point opposite the starting point upon the other side of the sole. the operator can remove the shoe and complete the severing of the trimming by dragging the sole over the stationarv knife after the machine has been stopped. thus brin 'ng the last cut out to the surface. if the soe is not of such shape that the movement of the cutter itself has etfected the complete severing of the trimming.

The nailed heel seat and the trimming rcmoved from a blocked sole are illustrated in Fig. 8. It will be understood. however. that the invention is not limited to nailing and trimming heel seats. It will be understood further that the invention is notlimited to the combination of trimming mechanism with nailing mechanism. but that it einbraces both the novelty in the various combinations. herein disclosed. of the elements of the trimming mechanism with the elements of the nailing or fastening inserting mechanism. and also the various features of noveltv of the trimming mechanism 1 c! It will be noted that the cut made bv the knife 24 is a paring cut as distinguished from a chopping cut or a drag cut. and that the nature of this cut contributes much to the practicabilit; of the employment of mechanism of this type in conjunction with fastening inserting mechanism. It will e noted further that the cut made by the knife or cutter 94 is produced by a movement f said cutter similar to the movement of the knife 24.

An important feature of the invention and one which has also contributed much to the practicability of combining trimming mechanism with fastening inserting mechanism is the arrangement by which the trimming cut is made after the shoe has been fed,

whereby no additional work is put upon the machine during the performance of its orthnary functions.

Although the invention has been shown herein as combined with a loose nailing mahine and also a combined With a loose nailing machine of particular type. it will be understood that it is not intended to restrict the invention to use either with loose nailing machines or with loose nailing machines of the type herein illustrated as it will be evident that the invention may readily be combined with other machines.

In some of the following claims reference will be made tc clamping the work after the work feeding operation or to holding the work stationary for the trimming operation, and it will be understood that the work support employed with this machine may be actuated to clamp and release the work by any suitable mechanism. such for example, as that ordinarily employed with the commercial loose nailing machine. A common type of work support clamping and releasing mechanism and one suitable for the purposes of the machine of this application is illustrated in United States patent to Louis (ioddu. No. 265.227. Sept. 26, 1882. reference being had especially to Figs. 1 and '2 of said patent. In Fig. 9 ot' the drawings tlllS work support clamping and releasing mechanism is illustrated sutliciently for the purposes of this application. A pawl carrying slide 130 is reciprocated by suitable connections with a cam groove formed in the front face of the rake disk 132. the illustrated connec tions comprising a rod 134 pivotally connected to one arm of a lever 136 fulcrumed at 138 on the machine frame. another arm of this lever carrying the cam roll l-LO which enters the cam groove in the brake disk 13-2. The pawl 1&2 is adapted to engage one of the ratchet teeth 1% upon r second slide 146 which has operative connection. through a lever in the base of the machine in the usual manner, with a jack supporting post 148. During the downward part of the reciprocarory movement of the slide 130. the pawl 1&2 is moved out of engagement with the ratchet teeth upon the slide 1&6 by means 1 f a pawl tripping plate 150. A spring 1.31, acting upon the jack post 148 in the usual manner. causes the jack to press the work against the guard plate 88 so that when the pawl again engages one of the ratchet teeth 144 on the slide 146 at a predetermined point in its path of movement. the amount of releasing movement imparted to the jack will be adjusted to the thickness of the work and the work wil\ be depressed each time the same distance from the guard plate.

It will be understood that the principal purpose of releasing the work after the clamping action is to permit the work to be fed freely. It will be understood further BEST AVAILABLE COPY that the invention is not limited to clamping the wo k to hold it stationary. but that other means may be employed to hold the work stationary for the action of the trimming mechanism and that such means need not necessarily be independent of the feeding mechanism.

While the present invention. in s far as the tools for cutting the sole are concerned. is intended primarily for the operation of rough rounding and randing the heel seats of boot and shoe soles. it will be apparent to those skilled in the art that many of the novel c mbinations of elements. which include the cutting tools. are adapted to a sole trimming operation. That portion f the invention relating to the cutting of the s le has. therefore. been purposely described by the use of broad terms. but the true scope of the invention will be found in the appended claims wherein the terms "r ugh rounding" and trimming are pr perly applied to the cutting tools in accordance with whether the whole combination claimed s novel for a heel seat rough rounding operation or the more comprehensive sole trimming operation.
