MACHINE FOR DRIVING PROTECTORS.

SPECIFICATION forming part of Letters Patent No. 768,812, dated August 30, 1904.

Application filed July 21, 1900.

TottZZ whmn it 777/CLU concern:

Be it known that I, BENJAMINF. IvIAYo, a

Machines for Driving Protectors, of which the followmg description, 1n connection With the accompanying drawlngs, is a specification,

like characters on the drawings representing like parts.

The novel machine embodying mypresent invention is provided with a carrier to transfer protectors from the raceway into position to be driven and a tongue to enter the space between the wings of a protector, the tongue being movable into and out of said space, as hereinafter explained.

In the mechanism herein shown as embodyingmy invention in one of the best forms now known to me the protectors, supplied to a raceway from any usual or suitable hopper, travel on the raceway and are acted upon in succession by an arrester and a let-oil. The protectors, prior to the entrance of the tongue into the space of the protector and after pass ing the let-ofi', come under the control of a protector-sustainer, which may be such as shown in my pending application, Serial No. 729,829, or as shown in Figures 6 to 14, incluo sive, or Figs. 25 and 26 of the drawings accompanying this application.

The carrier has two jaws forming a protector-receiving recess, and cooperating with said jaws is a tongue to position the protector accurately after it has been ejected from the raceway into the receiving-recess of the carrier. These jaws are opened slightly whenever the carrier comes into position to receive a protector, so as to prevent any binding as the protector enters the receivingrecess Serial No. M367. (No model.)

ing-recess whenever the carrier starts to move in the direction to place the protector in poof the delivery end of the raceway, and it is held normally pressed toward the raceway by a suitable spring, and the means for actuating the ejector to force a protector into the space of the carrier is arranged to yield, so as to prevent any damage in case of obstruction to the ejector in its descent.

I believe that I am the first to employ a tongue which is movable into and out of the space between the wings of a protector and also that I am thefirst to employ a carrier having a protector-receiving recess having coacting with it a tongue made movable into and out of said recess, and I therefore desire to claim these features of my invention broadly.

Manufacturers using protectors in heels and soles of boots and shoes usually insert them in a defined order, each protector occupying a definite position with relation to the next protector-to thereby present theornamental efiect desired. To enable this to be done, I have so formed the driver-passage that the operator, when the driver is elevated, may readily see the part of the tread of the heel or sole in which the next protector, is to be driven. This feature of my invention isof very considerable importance, and I desire herein to claim the same broadly in'whatever by the term in. a machine of the class d- 7 scribec as embodied in the claims, I'mean or body of the carrier detached.

, carrier shown in Fig. 17.

to include any machine capable of driving a protector, fastening, or slug into the stock.

Fig. 2 is a partial front elevation of the machine shown in' Fig. 1. Fig. 2 is a detail in front elevation of the lower end of the driver-lifting link and cam and a perspective view of theoperative position, the carrier and tongue being in their protector-receiving position, and the foot-plate holding a protector to be driven, the delivery end of the raceway and ejector being in section; Fig. i, a similar detail with the arrester and let-off both in their operative position, mostof the delivery end of the raceway being omitted to show the carrier supposed to be moving outwardly and clamping the protector. Fig. 5 is a view similar to Fig.- 3 with the let-off in its inoperative position and the tongue withdrawn from the carrier, the latter still .holding a protector. Fig. 5 is a detail showing the slotted end of the plate A. Figs; 6, 7, and 8 show the carrier and tongue and their sustaining means and the protector-sustainer more fully in different operative positions, these latter figuresbeing intended chiefly to illustrate more clearly the position of the protector-sustainer, which is but partially indicated'in Figs. 3, 4,-and 5, the views being below the line 4 4, Fig. 15.

25- and'26 are modifications to be referred to.

The column A of usual shape, the lower end of which is omitted, but which rests on the floor, supports the head A", of suitable shape, to sustain the working parts to be described;

The head has suitable bearings for a shaft 13,

having secured to it in usual -manner by a spline or otherwise a fast pulley B of the friction variety. The shaft carries a loose pulley B constantly driven by a belt and adapted to be thrown into driving contact with the fast pulley to impart motion thereto and the shaft on which it is fixed by means of a wedge-block B, actuated by the wedge B and rod B which is raised or lowered by a suitable treadle. The clutch-pulley device is common to United States Patent No.548, 528, dated October 22, 1895; but instead 1 may employ any other usual or suitable clutch mechanism to rotate the shaft when desired and to stop the same automatically at a predetermined point whenever the operator desires to stop it. The shaft B has fast upon it two cam-hu bs B and B to be described.

The wedge 13* is atthe end of a yoke-shaped piece B connected with the rod B said yoke having a suitable notch which receives in it an arm B (shown by dotted lines in Fig. 1,) extended from a sleeve B, suitably connected with a rock-shaft B having secured to its opposite end the sleeve of a lever B said lever at its upper end having adjustably connected with it one end of a brake-strap B, said strap embracing the cam-hub B and having its opposite end connected with a stud cf. Whenever the rod'B is elevated to clutch the pulleys and start the machine, the brakelever B is moved in a direction to release it from holding contact with the cam-hub B This brake can operate to clutch the hub 13 and stop the machine only at a defined point in the cycle of operations of the machine, and this time of action of the brake is controlled by a brake-cam B fast on the shaft B,'it having a depression which after the operator has removed his foot from the treadle or other device to release the upward pressure on the rod B is entered by a roller B carried by the lever B", the entrance of said roller in said depression causing the brake to act instantly and stop the rotation of the shaft with the driver in its elevated position,

as provided forin United States Patent No. 385,802, dated July 10, 1888.

The loose pulley B carries apinion C, which engages atoothed gear C on a shaft C having suitable bearings in the head A, said shaft having a suitable belt-pulley, as G which receives a belt A surrounding a pulley A (represented only by dotted lines in Fig. 2,) fast on a shaft A*, having suitable bearings in the framework and having fixed to its front end themovable part A of the hopper, having usual buckets to elevate the protectors and deposit them in usual manner upon the upper end ofa raceway A, provided with a- 'toward its lower end that the protectors will be delivered to the carrier with their wings substantially in horizontal position, said end (see Figs; 3 and ,5 to 16,) constituting a protector-positioning portion which maintains the protectors h each in exactly the same position at the end of the raceway. The protectors are placed in the chute or stationary part A of the hopper. (shown only in Fig. 2,) it forming part of an arm A herein represented as secured to a projection of the head A" by a suitable bolt A I am not aware that prior to this invention a hopper or device supplying a raceway with protectors, fasteners, or slugs has ever been moved continuously while the driver and other actuating parts of the machine were at rest. This feature is of very considerable advantage, for the reason that the raceway may be always kept supplied with protectors 6r fastenings, which is not the case in machines in which the .hopper is stopped when the driver is stopped. Owing, to the peculiar shape of the protectors, it is especially difficult to keep a raceway always supplied with them.

The machine herein to be described has a stock-support A, which will have imparted to it usual reciprocating movements to lower the same for feeding and to insure the rising of the horn to clamp the stock between itself and the usual nose or foot-plate preparatory to driving a protector, and said stock-support will in practice be depressed whenever the rod 1) is lifted, said rod being provided at its lower end with a carrier having a suitable dog to engage a ratchet-piece (not shown) oper atively connected with the horn-lever, all as provided for in my said pending application and as common to United States Patents No. 490,624, dated January 24, 1893, and No. 383. 155, dated May 29, 1888.

The upper end of the rod D is connected bya bolt D with the slotted end of a lever D having its fulcrum at D the opposite end of said lever having a suitable roll D, which enters a cam-groove D (Shown by dotted lines in Fig. 2 in the rear side of the cam-hub E The work-feeding device a, atoothed wheel, is moved intermittingly by or througha suitable toothed sector-lever a, in engagement with the teeth 602 of a pawl-carrier. Said sector has its fulcrum at a and'carries a stud a, which is engaged by a link (L in turn car,- ried by a stud a, adjustably mounted in a slot of an elbow-lever (0 which is suitably mounted in a bearing of the framework and provided at its opposite end with a roller-stud a entering a suitable cam-groove a in the rear side of the cam-hub B These parts are and may be substantially as now in use; (See United States Patent No. 405,835, dated May 21, 1899.) I have, however, mounted. this. shoe: feeding device in a;yoke (0 (shown in detail, Fig. 2,) said yoke being suitably guided in a part a of the head, the yoke being proscrew Z2 vided at its under side with a series offinclined teeth (1, which are engaged by the teeth of a worm a, fast on a diagonal shaft It will be understood that by the use of the yoke havingthe teeth and the worm I geta great range of adjustment for the work-feeding means, and no amount ,of pressure on the yoke by the pressure of the work against it during the operation of inserting protectors will move it longitudinally in its bearings, for the reason that the teeth of the worm serve as a locking device, and the yoke and the feed- -Wheel' may be adjusted readily at any time without unclamping any screws or other holding means which has heretotore been commonly necessary.

- The head of the machine has a tubular bearing E, in which may slide the driver-bar E, provided with a driver 6, secured to the driver-bar by asuitable. clamp 5' and set;

has a connected block 6 represented as-provided with a circular cavity to receive the circular lower end of a link 6, which end also receives through it when in said cavitya stud if, the stud forming, preferably, an integral part of the block, the link being confined on the stud by a suitable cotter-pin or otherwise. The upper end-of the link 7) is connected in like manner in a cavity at the end of the driveractuating-means, herein represented as-a lever 6 having its fulcrum at b and having cooperating with it a suitable spring 6 made adjustable in usual manner, the spring operating to depress the bar and cause the driver to act. This leverand spring are common in nailing-machines. Herein, however, I have provided novel means forlifting the driver, said means consisting. essentially, of a rod attached at its upper-end to a stud 6 extended from the lever 5 the lower end of said rod having a foot 6 (see Figs. 2 and 2",)

which is maintained constantly in contact.

with a suitable cam-5, (see Figs. 1 and- 2, and represented in detail in Fig.j2 ,)'said cam being applied to the end of the main shaft B, the cam being constructed to but partially surround theshaft, the shaft being cut away, as at 6 to complete the desired outline or shape of the driver-lifting cam. This construction is necessary inorder to provide a shaft B of suitable strength and yet provide for just the proper amount of stroke for the driver. The drive-bar Ebelow the block b is threaded at 6 and receives upon it a split collar 6,

The upper end of the driver-bar on the bar enables the downstroke of the bar and driver to be adjusted as desired.

The edge of the delivery end of the raceway, which constitutes a protectorposition ing portion, has a recess 0, (represented by 'dotted lines, Fig. 9,) and the plate A for keeping the protectors in proper line on the delivery end of the raceway is slotted at its lower end opposite the recess a, (see Fig. 5 said plate being connected to the positioning portion of the raceway by the braces g. This slot and. recess receive the lower end of an ejector 0, represented as a finger, (see Figs. 9 and 10.) bored at its upper end to surround an arm 0 which is connected with a rock-shaft '0 through a spring a, the opposite end of said rock-shaft having clamped upon it an arm 0*, provided with a roller or other stud 2, entering a suitable cam-groove at the rear side of the cam-hub B ,said cam being of the proper shape to depress the ejector whenever the carrier arrives in its protector-receiving position, the spring 0 between the arm 0 and .the rock-shaft a constituting a yielding connection in the actuating mechanism to allow the ejector to yield to any obstruction. The spring a, surrounding the arm 0 acts to keep the lower end of the ejector normally pressed toward the plate A and the edge of the positioning portion .of the raceway, so that in its descent it may enter the slot 0 (see Fig. 4) in the plate 9 and then the recess 0 meeting the 'upper edge of the endmost protector then surrounding the delivery end of the raceway (see Fig. 11) and ejecting it into the recess of the carrier, as represented in Fig. 9.

- I will now particularly describe the mechanism for letting off the protectors in suitable time and order and for operating the carrier that it may take a protector and put it in driving position. 1

The head of the machine is provided with suitable studs 3, (represented in Figs. 3 to 5,) which receive and act to maintain in proper position two plates (Z and g, the plate (Z underlyingthe plate 9, both of said plates having suitable screw-holes, as 5, through which are inserted suitable screws, which-enter the head and confine the plates cl and g in operative position. The front end of the plate Z is formed with an opening CZ, which leads into a throat or driver-passage CF. The outer end of said plate also has connected with it in suitable manner, as by screws d (see Fig. 10,) a footplate (2, which also has an opening on the side toward the operator. Forming the plate d and the foot-plate as described enables the operator to readily see the part of the heel or sole which is to receive a protector, so that he may place it in the desired position with relation to the protector. Thus, for instance, if the tread of the heel has been previously provided with fastenings or slugs 15, as represented in Figs. 3 and 6, said fastenings or slugs may be properly positioned by the opto allow the operator to see into the driverpassage.

The plate (2 has suitable side walls d", the inner sides of said walls constitutingaguideway for the main jaw or body of the carrier d provided at or near its rear end with a shouldered stud d, on which is applied a suitable roller 6Z7, said roller entering the camgroove d in the cam-hubBfi the cam moving the carrier to and fro, as herein represented, in a right line that the carrier-recess, to be described, may receive a protector at one end of the stroke of the carrier and deliver the protector at the other end of the stroke of the carrier, in the line of travel of the driver 6. The main jaw of the carrier is provided at its front end with a notch d, (see Fig. 17,) forming one-half of the receiving-recess, and an abutment al The plate has also a notch al at one side, crossing a recess d, having a hole 5Z The plate of has at its under side a circular chamber al in the center of which stands a stud al on which the gear f rotates, a part of said recess and the under side of the plate being cut away, as at d, forming a housing for the link f hereinafter described. The secondary jaw e of the carrier (represented as detached in Figs. 20 to 22) has a central stud e, which enters the hole al and the width of the jaw e is sufliciently narrower than the recess 03 to permit said jaw to vibrate about the stud e as a center. The rear end of the jaw 6 has an inclined face e and near its front end it has a face 6 and an abutment e* extended therefrom, said face coacting with the side of the recess (is and constituting the protector-receiving recess of the carrier, the abutments d and a receiving against them the free ends of the wings of a protector. The rear end of the jaw e, as herein shown, has a recess 6 in which is located a suitable spiral spring e, (see Figs. 6 to 8, the opposite end of said spring entering a suitable recess in the side wall 6 left at the end of the notch (Z of the plate 6Z5, said spring normally acting to to move the face-wall e of the jaw 6 toward the notched part d to clamp a protector placed in the recess of the carrier. The jaw (2, however, must be opened at the proper time, and to provide for this a side wall d of the plate d is provided with a block having an inclined face a, held in place by a suitable screw 0 the inclined face 6 meeting the inclined face a when the carrier arrives in its protector-receiving position.

The upper side of the plate 61 has a groove f, (shown best in Fig.16,) which receives a bar f, having secured to its front end by suitable screws f a tongue f The bar f has a suitable hole, (see Fig. 16,) which is entered by a projection f, extended downwardly, as herein shown, from a link f having at its other end a suitable studf, (see Figs. 6 and 24,) which enters a hole in a partial gear 3, having a central hole which fits loosely over the stud 0Z extended downwardly from the plate d the under side of the gear being cut away, as represented by the dotted line, Fig. 6, to form a space at one side the center of motion of said gear, in which may enter one end (see Figs. 6 and 16) of the link f said link being located in the space al cut in the under side of the plate d bar referred to constitute wh at may be hereina'fter' termed an actuator for the tongue. The gear f projects somewhat from the edge of the jaw or carrier (Z and is engaged by the teeth of a rack-bar f secured to the plate d by screws f seated upon the upper side of the plate d by means of suitable gibs f, held in place by suitable screws f. v

The plate g before referred to contacts with and constitutes a sort of covering-plate for the carrier J, and the plate has (see'Fig. at) a suitable slot a, beveled at one end, as at 10, through which may descend the ejector c, and an opening 12, leading out to the front end 16 of the plate g. The lower end of the raceway-cover A enters the opening 12, and the remaining portion of the opening forms a space to receive the delivery end of the raceway.

The plate g has a central space 17, (see Fig. 9,) which is entered by the stud (Z erected on the carrier 6Z5, said stud in the movement of the carrier operating the protector-sustainer and the arrester and let-01f, to be described. The rear end of the plate g is notched, as at 18, for the reception of the stud d as the carrier is actuated, and there are left under the rear end of the plate g suitable spaces to receive the outer ends of "levers g, herein represented as constituting one form of protector-sustainer, said levers being united at their rear ends by means of a suitable spring 9 which acts normally to cause the opposite ends 19 of said levers to approach each other. This sustainer in the form in which I have chosen to illustrate it in Figs. 6'to 8 coacts with the delivery end of the raceway in such manner'as to keep the protector it, (see Figs. 11 and 14,) located at the deliveryend of. the raceway and next to be discharged from said delivery end by the ejector in the proper po- The gear, link, and

The carrier d is kept properly sition until the protector-receiving recess of the carrier arrives in position to receive the protector, the sustainer at such time retiring from the side walls of the winged protector that the ejector may put the protector into the space of the carrier. The ends 19 of the sustainer, as herein represented, contact with the side walls of the delivery end of the raceway at a point at or near its extremity, the sustainer being moved into inoperative position by stud d as represented in Fig. 6, whenever the carrier arrives in its protector-receiving position, (see Figs. 3 and 6,) the space of the carrier in such position being opened by the contact of the inclined part 6 of the jaw e with the inclined part a. Y

The plate 9 has a depending stud 9 which serves as a fulcrum for the levers g, and said stud is extended sufficiently above the plate g to enter a suitable hole in a bridge g, (shown as attached to said plate 9 by suitable screws 9 The stud g receives upon it under the bridge 9 a suitable arrester g and a letoff 9 said arrester and let-ofi being herein represented as operatively connected by a suitable spring g, the arrester having a prong g, which, as best shown in Figs. 4: and 5ymeets the side of a protector, as it. (See also Figs. 13 and 14:.) The letoff g has a prong g which at times sustains the protector'next below the one which is acted upon by the arrester. The arrester and let-off are located facing each other, the arrester being above the letofl', and they are moved, as herein shown, alternately away from the racewayterminal into their inoperative positions 'by the stud (Z and into their operative positions, as herein shown, by the spring-'g The stud d 18 acts to move the arrester into its abnormal or inoperative positon to release a protector only as the carrier arrives inits protector-receiving position, the let-off at such time bein'g'in its operative position to receive and sustain the protector released by the arrester, and as the carrier is moved from its protector-receiving position into position to have a protector driven therefrom the arrester under the control of the spring g is next back of the protector then resting on the let-ofi'. As the carrier arrives in position to give up its protector the let-ofl" is met by the stud d (see Fig. 5) and moved from under the protector then resting upon it, permitting said protector to travel on the raceway from the position Fig. 13 into the position Fig.14E, the protector-sustainer at such time occupying a position to hold the protector released, as described, at the delivery end ofthe raceway in proper position to be struck at its upper end by the ejector 0', which is made to descend as the carrier arrives in its backward movement with its recess under the end of the raceway in protector-receiving position. In this position of the carrier the tongue made to approach and meet the protector f stands substantially in vertical alinement With the protector-positioning portion of the raceway and the jaws are open, (see Figs. 6, 9, and 12,) the protector-sustainer occupying a position to give up the protector which was under .its .control as the carrier arrives substantially in its protector-receiving position. The tongue f when the sustainer gives up the protector under its control and the latter is acted upon by the ejector, stands in the receiving-recess of the carrier, but is slightly Withdrawn, so that the protector or slug may enter the receivingsrecess of the carrier freely and straddle the tongue, as in Fig. '9. When the protector has entered the receiving-recess of the carrier and the carrier has started forward toput the protector into driving position, the tongue at first enters farther into the space between the walls of the protector (see Figs. 4 and 10) and seats the body of the protector, from which the wings extend, in the recess of the carrier; but as the carrier is moved from its protector receiving to its protector-delivering position (see Figs. 5 and 11) the tongue travels with the carrier, but at a faster speed, so by the time that the carrier arrives in its protector -delivering position the tongue by its movement has been withdrawn from the space between the wings of the protector, leaving the protector, however, clamped in the recess of the carrier. From the foregoing it will be under' stood that the tongue while traveling with the carrier is moved to and fro in the recess of the carrier and in the space of the protector by means of the actuator. Fig. 6 shows the carrier in its protector-receiving position, and as the carrier arrived-in this position the gear f was turned by the rack f in the direction of the arrow thereon, causing the pin f to cross a line intersecting the stud d and the projection f which caused the tongue to be withdrawn slightly from the recess of the carrier. At the same time the jaw e meets the inclined face a and is moved to enlarge the recess of the carrier that a protector on the raceway, which is acted upon by the ejector, may enter freely the recess of the carrier and em brace the tongue then in alinement with the positioning portion of the raceway. A protector having been deposited in the recess of the carrier about the retracted tongue, the carrier is started to place its protector in position to be driven, and the gear f is rotated in a direction opposite the arrow, Fig. 6, causing the stud f" to pass behind the stud (Z which moves the tongue in opposition to the movement of the carrier, so that the tongue enters farther into the space between the wings of the protector, seating the protector firmly in the recess of the carrier. As the carrier is moved forward from the position Fi 7 into protector-delivering position, Fig.8, the gear f is rotated by means of the rack-bar with which it is in engagement, and the link f which connects the gear with the tongue-bar f, moves the tongue-bar, with the carrier, but

at a fasterspeed, which withdraws the tongue tages to be derived from the open driverpas 4 sage, showing howthe operator may easily see just where the protector is to be driven. Theline 100 represents the outline of a heel, in the tread of which the protector is shown as driven, the figures also representing that a series of fastenings or slugs have been previously driven into the heel and that their ends have been left exposed that they may be embraced by the protectors.

In case it is desired that the outer end of the protector stand somewhat above the plane of the tread of the heel such driving of the protector may be insured by adjusting the collar Z) on the driverbar;. but that a protector not fully driven may not obstruct the feed of the shoe 1 provide the under side of the footplate with a recess 13, (see Fig. 15,) said recess being formed in said foot-plate at that side in the direction of the feed of the shoe.

Fig. 11 shows the ejector in inoperative position, its edge resting against the plate A the end of the ejector standing close to the lower end of the protector then held by the end g of the arrester, (see Fig. 14,) the letoff being in its inoperative position, it having been moved from its position Fig. 13 and having permitted the protector held by it to travel to the end of the raceway, while the protector-sustainer occupies its operative position to maintain the protector in proper position to be put into the recess of the carrier by the ejector. VV'hile the carrier is being moved from the position Fig. 11 into the positions Figs. 9 and 12, the let-off is first put by the spring into its operative position, and the arrester is then put in its inoperative position, the protector held by it, (see Fig. 1 1,) descending to the let-off, Fig. 12. As soon as the carrier arrives in its protector receiving position and the protector-sustainer is moved to permit the protector held by it to enter the open space of the carrier the ejector descends from the position Fig. 11 and meets the incline or bevellO (see Figs. 9 and 10) at the end of the slot 0 (see Fig. 4) in the plate g, causing the ejector to contact with the said protector, forcing it from the raceway-terminal into the open space of the carrier, as in Fig. 9. Then the carrier is started forward or to the right, and the arrester comes into its operative position to meet the protector next back of the one then resting on the letofi', after which, as herein provided for, the ejector is put into its inoperative position, and as the carrier arrives in its delivery position the let-off is put into its inoperative position, releasing the protector held by it, that it may descend and be under the control of the protector-sustainer.

Figs. 25 and 26 represent a modification of my invention wherein the tongue is differently actuated and the construction of the protectorsustainer is modified. Referring to these figures, represents an equivalent for the plate CZ, it having pivoted upon it at 41 the body or main jaw of a carrier 42, having a notch, said carrier having pivoted upon it at, 43 a cooperating jaw 44, also havinga notch, said notches constituting the protectorreceiving recess. The main jaw or body 42 of the carrier has pivoted upon it at 45 a bar 46, provided at or near its free end with a tongue 47. The body 42 of the carrier is slotted at 48 to receive a stud 49, extended from the plate 40, and one edge of the bar 46 has an inclined face 49, which is normally kept pressed toward the stud 49 by means of a suitable spring 50, interposed between one end of the bar 46 and a part of the body 42 of the carrier. The jaw 44 has, as represented, an extension 51, to which a spring 52 is attached, the opposite end of said spring being connected with a stud 53, extended from the bar 46, said spring acting to keep the bar 46 against the stud 49 and also to normally keep one edge of the jaw 44 in contact with the body 42 to thereby close the recess in the carrier to grasp a protector. The plate 40 has a slot 54, which is entered by a pin 55, depending from the jaw 44, and Whenever in the movement of the carrier the latter arrives nearly in its protector-receiving position, as in Fig. 25, the pin meets the end of the slot 54 and stops the further movement of the jaw 44,. while the body 42 of the carrier completes its full stroke, thus opening the recess of the carrier for the reception, from the usual delivery end of the raceway, of the protector then to be put into the recess of the carrier. When the carrier arrives in its protector-receiving position, the inclined face 49 acts against the pin 49 and slightly Withdraws the tongue from the recess in the carrier to thereby afiord free entrance of the protector into said recess, the protector straddling the tongue. The plate 40 has a nose or throat-plate 56, through which the protector is driven from the carrier when the latter is moved fully to the right, thus putting the protector in position over the opening in the throat. As the carrier starts from its receiving position (shown in Fig. 25) toward its delivery position the inclined face 49 passes the pin 49, permitting the tongue to farther enter and seat the protector in the recess of the carrier, and as the pin 55 retires from contact with the end of the slot 54 the spring 52 acts to close the jaw44 of the carrier, thus clamping the protector and maintaining it clamped until the protector is driven from the carrier by a suitable driver. The plate 40 and the throat-plate 56 are slotted,

as described, facing the operator to thereby expose the stock into which the protector is next to be driven. The body 42 of the carrier may derive its motion from a link 57, which may be reciprocated in any usual manner. The bar-46 has an inclined face 58,\vhich when the carrier comes into its protectordeliverin position meets an inclined face 59,which withdraws the tongue 47 from between the wings of the protector. In this modification of my invention the protector-sustainer is represented as composed of two

levers

60 and 61, pivoted, respec tively, at 62 and 63 to a stationary plate (not shown) above the carrier. The levers are jointed together by a link 64, and a spring 65 acts normally to cause the free ends of the protector sustainer to approach each other. Viewing Fig. 26, it will be supposed that the carrier has been started slightly toward the right to put the protector then between its jaws into driving position, and the sustainer is represented as covering the protector just delivered into the recess of the carrier, and in this position the next protector to be taken from the raceway and put into thecarrier-recess is permitted to drop upon the sustainer. As the carrier moves to the right the pin 67. extended upwardly from it, will meet the right hand end 66 of the space in the jaw 60 and acting upon said jaw will, through the link 64, cause the separation of the free ends of the sustainer a little before or just as the space of the carrier containing the protector arrives in position to have the protector driven through the throat 56. This movement of the sustainer permits the protector which rested upon it to descend upon the upper side of the flat portion 68 of the body 42 of the carrier. The protector having been driven, the carrier is started toward the left to again receive a protector when in protector receiving position, and the protector which next goes into the space of the carrier is the one resting on the face 68 of the body 42 and then held between the faces of the

jaws

60 and 61. As the carrier arrives in its receiving position the pin 67 -meets the jaw 61 of the protector-sustainer and through the link 64 also moves the lever 60, thus separating the acting ends of theprotector sustainer andv releasing the protector that it may drop into the open space of the carrier, straddling the tongue 47, as in Fig. 25.

Having described my invention in one of the best forms known to me sufficiently to enable the same to be understood, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine for inserting heel or sole protectors having laterally-extending wings, a driver, and a movable carrier to receive a protector and present it in position to be driven, said carrier having a tongue to enter the space between the wings of the protector,

' and means for moving said tongue out of the space between the wings of the protector.

2. In a machine for inserting heel or sole protectors having laterally-extending wings,

a driver, a carrier to receive a protector and g draw said device before the protector IS driven.

present it in position to be driven. said carrier having a tongue to enter the space bc- I tween the wings of the protector, and means independentof the driver for moving the.

tongue out of the space between the wings of the protector.

3. A movable carrier having a protectorreceiving recess, a tongue, a bar carrying said' tongue, and means to actuate said bar to move thectongue into and out of the recess of the carrier.

4:. In a machine of the class described, a movable carrier having a recess to receive a protector, a movable tongue occupying a position in the recess of the carrier as a pro tector enters said recess, and means to cause said tongue to enter farther the space between the wings of the protector and position the same in the recess of the carrier.
