SPECIFICATION forming part of Letters Patent No. 768,811, dated August 30, 1904.

Application filed September 8, 1899. Serial No. 729,829. (No model.)

To all 11117710111 it may concern:

Be it known that I, BENJAMIN F. MAYO, a

citizen of the United States, residing at Sa-j lem, in the county of Essex andState of Bias-- sachusetts, have invented an Improvement in Machines for Driving Protectors, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. a

This invention is intended as an improvement on the class of machine represented in Letters Patent of the United States No. 741,522, granted October 13, 1903, said patent showing and describing a machine for inserting protectors or protective slugs, as they are therein styled, into the heels or soles of boots orshoes, said machine being adapted to drive protectors of varying shapes, some of which are therein shown.

The machine of this application is shown as adapted to drive protectors of rectangular shape; but, as explained in said United States Patent No. 741,522, the machine may readily be changed so that protectors of different shapes may be driven. In said patent the protectors are shown as guided by a in forming a raceway, each protector riding on said lin to the delivery end of the raceway, each protector as it arrives at the end of the raceway being deposited on a smooth surface forming a part .of a movable carrier provided with a space or recess, which the protector is expected to enter; but sometimes it, happens that a protector fails to enter the said space or recess correctly, owing to the fact that in the movement of the carrier one edge of the recess comes first under one part, wing, or half of the protector and then under the other, so that the unsupported part or wing of the protector may start to enter the recess while the other part or wing rests on the top surface of the moving carrier at one side of the recess, and consequently the protector is liable to be partially overturned.

The use of the machine referred to has demonstrated the great desirability of maintaining perfect control of the protectors from the time that they enter the raceway up to the time they are acted upon by the driver to be driven intothe stock, for it will be understood that the protectors must be driven into the stock accurately, so that their wings or open ends will occupy exactly the desired predetermined position; otherwise the figure or pattern made by driving the protectors will lack uniformity in general appearance or will be distorted or marred.

Herein I have made the carrier in two parts, movable with relation to each other, thus making it possible to enlarge the protectorreceiving space in the carrier when the latter comes into position under the raceway, thus enabling the protector to drop easily into said space. The parts of the carrier are then brought together to clamp the protector while the carrier is moved to put the protector in positionto be driven. I

The carrier is provided with an inner guide which occupies a position in the space of the carrier and is straddled by the protector lying therein; but herein the said inner guide is represented as somewhat longer to project farther into the space formed by the wings of the protector.

The raceway herein employed may be like the one shown in said United States Patent No. 7 Il,522 or one adapted to guide and keep said protectors from rotating indiscriminately during their passage toward the delivery end thereof, at which point, while the protectors straddle the positioning portion and are surrounded by a lip, instead of letting the protectors off one at a time upon the top of the moving carrier, as therein provided for, I have provided at the end of said raceway means whereby it is possible to ,insure that the protectors leave the raceway or positioning portion without turning or twisting, the best form of which now known to me consists of 'yet under the control of the positioning portion 'of the raceway, each protector in succession com ng to and being held by said protectorsustainer until the carrier, having the recess for the reception of the protector next to be driven, is actuated to put said recess in vertical alinement with the delivery end of the raceway and immediately under the protector next to enter said recess. When the carrier is in this position, the protector-sins tainer is quickly actuated to release the protector, so that it may leave the raceway or positioning portion thereof and without twisting or turning enter the recess of the carrier and straddle the inner guide thereof.

Herein it will be noticed that the sustainer represented is adapted to be operated in such manner that both wings of the protector are released substantially simultaneously,'so that the protector is free to drop into the recess of a protector becomes stuck at the delivery end of the raceway and does not drop. in time said ejector will act on the upper end of the protector and push it instantly into the space of the carrier. I

Preferably the jaws of the carrier will clamp the protector. with a yielding pressure'until the end of the driver, the latter having its.

acting end shaped to meet the protectors and straddle the inner guides and presenting a longitudinal groove at one side, meets said controlled protectors one after another and drives them from the carrier through the throat of the nose or foot plate, which is provided with an inner guide, into the stocksupported on a horn, they having had no opportunity to turn or twist.

The driver herein employed is novel, it being slotted at onev side, commencing at its acting end for a considerable portion of or substantially throughout its length, said slot enabling the driver to pass the inner guide of the carrier and the inner guide in the throat of the foot-plate, these inner guides extending, as already explained, for a considerable distance into the protector passage. driver is made adjustable, by means to be described, to not only provide for driving the protectors flush with or below or above the surface 'of the stock, but also to compensate for any shortening thereof by reason .of wear in grinding.

Figure 1 in front elevation represents a sufiicient portion of a machine for inserting protectors with my improvements added to enable my invention to be understood,,the so-called binding-block w and the spring .for nor.

The

Fig. 5 is an enlarged end elevation of the parts shown in Fig. 4:, but with the binding-block w removed. Fig. 6 shows the binding-block detached and with it the latch w holding the slide D Fig. 7 is a section of Fig. i on the line 00 Fig. 8 is a view showing some of the parts represented in Fig. 4, but in difl'erent positions. Fig. 9 is a section in the line 0 Fig. 8. Fig. 10 shows the carrier in position to receive a .protector, its jaws being open, the protectorsustainer being represented in dotted lines and being shown as open, the binding-block to being omitted. Fig. 11 shows the carrier closed and in its position to deliver a protector to the throat, the protector-sustainer being .then in its closed position. Fig. 12 is a detail showing part of the carrier with its inner guide.

Referring to the drawings, A represents a column; A part of the head; I), part of the head or frame carrying the driver-bar D a a rock-shaft carrying an arm 6/, having attached to its lower end a link a, engaging a stud a (see'Fig. 4,) extended from a carrier at, pivoted at (1 6 represents an arm pivoted at b eccentric with relation to'the rock-shaft (1 carrying the arm a.

(Z is a block adjustable in a groove in the face of the arin a, (see Fig. 4,) said block having a clamping-screw d, which is extended through a slot in the lever b, the adjustment.

of said clamping-screw and block longitudinally in said slots providing for the desired throwof the feed-slide 6 joined to said lever b, the horn C and the plate clhaving holes (V to receive suitable bolts. (Not shown.) Said bolts in practice being first extended through holes 03 in the foot-plate D are all substantially as shown and described in said United States Patent No. 7&1,522 and so do not need to be herein further specifically described.

The raceway herein shown presents a fin, the receiving end a of which is supplied with protectors from the hopper E", said fin between its receiving end and itsdelivery end or protector-positioning portion 6 having given to it a quarter-turn, (see Figs. 1 to 1",) so that a protector 20 applied to the receiving end and straddling the fin will ride thereon to said delivery end or positioning portion a and during its passage will be turned into such position as to present the open end or wings of the protector toward the front of the machine or in the desired established posit-ion required for the work to be done.

- To prevent the protectors from jumping off the fin, a cap a is provided, having its lower end widened and bent to form lips-6?, which encircle the fin and embrace the exterior of the protectors straddling the positioning portion a thereof, the ends of the lips being connected to the positioning portion of the fin, as shown in Fig. 4, and having suitable openings in their sides for the reception of the acting ends of the arrester and let-01f. The arrester a is pivoted at a on the plate (Z, and the letoff f is pivoted at f" on the same plate, springs a and f cooperating with the said arrester and let-off, as hereinafter described.

The carrier herein represented comprises a lever'or moving device a, pivoted at a said device having pivoted upon it at a a jaw a.

The. jaws a and a are each cut to form a space a, Fig. 12, for the reception of a pro tector, said space being provided with an inner guide or tongue 31, represented (see'Fig. 12) as held in position by means ofa suitable screw, as 32, the two jaws being normally kept closed by or through the action of a suitable spring a, the opposite ends of which engage like studs a, one extended from the part a of the carrier and the other from the jaw member a The movable jaw a has connected with and extended below it a pin a, (see Figs. 10 and 11,) which enters a slot at in the foot-plate'D. When the carrier is moved from the position (see'Fig. 11) where it presents a protector to the action of the driver into position toreceive a protector, (see Fig. 10,) the pin a of the jaw a is arrested by contact withth'e'end of the slot a before the part a of the carrier completes its full stroke, thus effecting the opening of the jaws to enlarge the space in the carrier, that a protector let off from the posi tioning portion of the raceway may enter said space freely and without liability of meeting the side walls thereof, the wings of the pro' tector entering said space straddling the inner guide 31.

put at the same time into its operative posi tion by a spring'f connected with the arrester, the stop coming in position at the lower end of the raceway to receive upon it the endmost protector on the raceway and hold it and all those back of it.

When the carrier is moved from the posi tion Figs. 4 and 10 into the position Figs. 8, 9, and 11, the pin a retires from the arrester,

letting the spring (6 actuate the arrester to meet a protector next back of the endmost protector sustained by the stop f said pin a in its further movement tothe right meeting said stop and moving it into the positions Figs. 8 and 9, removing the stop from below the endmost protector and letting it drop therefrom upon the protector-sustainer, to be described. The arrester and stop work alternately and each is moved by the pin a into its inoperative position, each being put into its :said endmost protector, the arrester sustaining said protector and those back of it when the let-off or stop is withdrawn from under the leading end of the protector next to'be delivered from the raceway into the carrier.

The carrier'hereinrepresented is moved to and fro, as provided for in'said United States Patent No. 7tl,522, it being at times moved to the left, as shown in Figs. 4c and 10, to place the protector-receiving recess thereof opposite the lower or'delivery end of the raceway in order that said recess may receive a protector between its open jaws, said carrier being then moved to the right into position Figs; Sand 11 to put the protector straddling the inner guide 31', and inclosed between and clamped by the jaws of the carrier, over the passage in the bushing of the foot-plate D descends through the driver-passage (Z in the plated (see Figs. &, '7, and 9) may enter the recess in the carrier and drive the protector therefrom through the passage in the Ioo IIO

andu'nder the driver, so that the latter as it bushing 1 into the stock S, part of which'is shown in Fig.9, said stock being supposed to be sustained'upon the upper end of the yield ing horn or work-support C, (partially shown in Fig. 1,) it being the same as the work-support shown in saidUnited'States Patent No. 741,522.

Herein the fin e of the raceway to be straddled by the protectors is represented as pro vided at a short distance above its acting surface with'a cover or cap 0 which overlaps the central portions of the series of protectors i 20, some of which are shown hangingupon said-fin in Fig. 1.

The protector-sustainer in the form in which I have herein illustrated it, it being one of the best forms now known to me, consists, essentially, of two members or plates 23 and 24, the member 23 being pivoted upon a stud 21, while the member 24 is pivoted upon a stud 22, said studs (represented by dotted lines in Fig. and in section, Fig; 11) depending from the under side of the plate 01.

The member 23 is represented as having a slotted space 25, and the faces of the members are normally held closed, as represented in Fig. 11, by a suitable spring 26, engaging at one end the member 23, the outer end of said spring (see Figs.v 1, 4, 5, 7, and 9) being connected with a stud 27, fixed at one edge of the plate d. The spring 26 acts normally to keep the members 23 and 24 closed, as in Fig.

11, said members constituting what I have arres'ter a at such time acting against one'side of the protector next above the endmost protector of the series, as represented in Figs. 8 and 9. The protector-sustainer receives upon it and supports, as shown, the lower end of the protector while the carrier is in the position shown in Fig. 9 and 11, the jaws of the carrier through the spring a then clamping or holding a protector in position to be driven therefrom through the protector-passage in the throat of the foot plate or block as the driver 28 to be described descends.

After the driver-bar or carrier D has been operated to drive .a protector and has risen into its elevated position the carrier is moved from the position shown in Figs. 9 and 11 to the left into the position Figs. 4, 5, 7, and 10, and during this operation the pin a meets not only the arrester, but also the member 24' of the sustainer,turning said member 24 about its stud 22, causing the corner 29 of said member, acting against a part of the member 23, to move the member 23 in substantial unison with the member 24, but in an opposite direction, so that the acting faces of said members which may contact substantially under the end of the raceway are separated or moved, as herein represented, in opposite directions, enabling the endmost protector to be instantly released, that it may leave the protector-sustainer and positioning portion a (see Fig. 7) and without twisting or turning enter the recess co (see'Figs. 5, 7, and 10) of the then open jaws of the carrier, it being understood that as the carrier wasmoved to the left, as described, from the position Figrll into the position Figs. 7 andlO, thepin'cfl'extended from the jaw a, met the end of the slot (4 and arrested the said jaw a, while the portion a of the carrier continued to move, thereby enlarging the recess in the carrier for the ready admission of the protector, it straddling the inner guide 31 therein.

- It is essential that the protector be guided or controlled and. prevented from tipping or twisting or from turning axially in going not only from the raceway or its protector-positioning portion a into the carrier, but also into position to be driven, and I have effected this substantially positive control through the protector-sustainer and by providing the carrier with the inner guide 31.

The head 1) containing the driver-bar D means for moving the driver-bar up and down, and 'the horn are substantially the same as found in United States Patent No. 490,624,

490,624, dated January 24, 1893.

I believe that I am the first in a machine of the class herein described to make the carrier so that it may be separated as a jaw to enlarge its protector receiving space and also the first to provide a carrier composed of jaws with an inner guide, and I also believe that I am the first to use at the endof a racewayin a machine for inserting slugs or metallic fastenings an independent sustainer of any form so constructed and operated as to insure the slugs or protectors leaving the raceway without tipping, twisting, or turning, and I desire to claim these new features broadly in whatever form they may be embodied or in whatever machinethey may be used.

Ashereinbefore stated, the pina in this instance of my invention performs a double functionthat is, it operates both the arrester and the let-ofi, as provided for in said United States Patent No. 741,522, arid also the protectorsustainer. The protector-sustainer would be of very material value even were the inner guide 31 of the carrier omitted.

To insure the proper appearance of the heel or other part of a boot or shoe provided with protectors, it is essential that the carrier be always provided with a protector, so that a protector may be driven at every operation of the driver. Ordinarily the protector released by the stop or let-off will drop properly upon the sustainer, and the latter will then release the protector and let it drop by end of the protector-receiving portion of the raceway into the open space of the carrier, and to prevent this I have provided the machine with an. ejector which will act positively to put the endmost protector of the series of protectors-viz., the one below that acted upon by the arrester-into the open space of the carrier. This ejector in the form in which I have herein represented it consists, essentially, of a lever t, pivoted upon astud t, carried by an ear or projection 25 of a slide-bar t said slide-bar being slotted at its upper end, as at 25*, to embrace a stud t extended from anear i suitably held'in the head D.

- The slide-bar has a pin 6 which enters a slot t in the end of a radius-bar t", pivoted at t, on the usual back plate or stationary part of the rotating hopper or protectorpot E", common to said United States Patent No. 74:1,522, said hopper being sustained upon an arm E suitably pivoted at its inner or right-hand end upon the framework of the machine. The radius-bar t has a projection and a suitable spring 6 connected with said radius-bar and with a stud t of the head D, normally acts to lift said radius-bar and the slide-bar t keeping the projection i of said radius-bar in the range of movement of a cam projection 25, forming part of the usual disk connected with the main shaft of the machine-2i shaft which may be substantially such as the shaft marked G in said United States Patent No. 490,624, dated January 2 L, 1893 it carrying a cam projection Z to meet the block t connected with the driver-bar, to lift it in usual manner. The cam projection i is extended by a cam-surface t which extends for about one hundred and twenty degrees of a circle. The lower end of the ejector t is squared and shaped to present a toe projecting from one edge of the ejector below a recess 6, a spring 6 connected with said ejector, normally acting to keep the toe at the lower end of the ejector i n contact with the lip 6 surrounding the lower end of the protector positioning portion e of the raceway, which terminates in an opening t in the plate cl, said positioning portion having at that side or edge straddled by the protector a groove, as 25 Fig. 1 shows the ejector in its mostelevated position, the projection t just above and in contact with the projection i ready to desustainer having been put into position to afford a passage for the protector into the space of the carrier and the ejector having acted to push the protector into said space, the spring 25 immediately elevates the ejector into the position Fig.1", the part 6 0f the cam acting against the part of the radius-bar to retain the ejector in this position until the arrester has engaged the protector next to the endmost protector on the raceway.

The ejector operates while the carrier is in the position Fig. 10, and in such position it will be understood that the stop acts to hold vback the series of protectors next back of the one which was deposited upon the closed sustainer when the" sustainer and carrier occupied the position shown in Fig. 11, and when the ejector acts it will be understood that the arrester occupies the position Fig. t. As the ejector. rises from the position Fig. 1, it be ing supposed that a protector has been properly put into the recess of the carrier and the carrier'closed and'started in its movement to the right from Fig. 10 into the position Figs. 9 and 11, the arrester acts to meet the protector next back of the one sustained by the stop and hold the column of protectors against vertical displacement while the ejector completes its ascent. at its highest position, the stop or let-off f is moved by the pin a 'letting the endmost protector on the positioning portion and sustained by said stop drop upon the-sustainer, the arrester serving to hold the protector acted upon by it and all those back of it.

The driver 28 herein shown is provided, commencing at its acting end, with a longitudinal recess 33. (Shown best in Fig. 3, where the driver is represented in end view, said recess being also shown by dotted lines in Fig. 1.) The recess in the driver is ren- The ejector having arrived dered necessary by the use of the long inner guides 31 and 31 referred to, said guide or guides standing between the wings of the pro' tector when the driver descends to meet the protector and drive it. During the operation of the driver in driving a protector the groove 33 travels over the said inner guide or guides. The driver runs in a driver-guide 34, secured in suitable manner to a part of the framework, as by screws 35. The upper end of the driver has a shank provided with a screw-threaded portion 36, which engages the screw-threaded interior of a sleeve 37, the upper end of the shank entering a hole in the end of thedriverbar, where it is locked in position by means of a set-screw 38. 'By loosening the screw 38 and turning the sleeve 37 these threads acting on the threads of the shank 36 of the driver enable the position of the driver to be the raceway and covers a hole w, (shown by,

dotted lines,) made in the under side of the footeplate, and when it is desired to take off any protectors on the raceway the slide may be removed, afl ording ready access to the raceway. To keep this slide always in its proper position, there is applied to the front end of the plate cl a binding-block a), which is confined to said plate cl by screws w The front side of the binding-block has a latch w pivoted thereon at 20 and having a notch to fit the reduced end of the slide D Then it is desired to remove the slide in order that any protectors on the raceway may be taken oif through the hole w, the operator lifts the latch 12: and withdraws the slide.
