SPECIFICATION forming part of Letters I Patent N o. 467,242,dated January 19, 1892.

Application filed April 19I 1887. Serial No. 235,316. (No model.)

.To all whom, it may concern:

Beit known that 1, CHESTER C. SMALL, a citizen of the United States, residing at Malden, in the county of Middlesex and State of Massachusctts, have invented a new and useful Improvement in Heel-Attaching Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this 1o specification, in explaining its nature.

The invention is an improvement upon that described in the application of Freeborn F. Raymond, 2d, executed April 16, 1887, Serial No. 234,985, and it relates, especially, to various details of organization and construction whereby the machine described in said application is simpliiied and improved. This result is obtained in part by making the templet stationary instead of movable and by zo making more direct'connections between the various operative parts.

Referring to the drawings, Figure 1 is avertical central section ofthe machine without the nail-feeding devices. Fig. 2 is a View in z5 rear elevation thereof. Fig. 3 is a view in plan and horizontal section below the line x u: of Fig. 1. Fig. 4 is a view illustrating the cam and connections for moving the heel-blank and top-lift-feeding devices and also a por- 3o tion of the devices for moving the heel-blank and top lift from their respective stacks into a position to be moved by their respective carriers. Fig. 5 is a view in plan of the cam and also a portion of the connecting mechanism for moving the heel-blank and top-lift slides. Fig. 6 is a view in plan of the cam and connections for moving the jack out of operative position upon the rotation of the work of the machine. Fig. 7 is a view in rear elevation of the cams for rotating the head. Fig. 8 is a view in front elevation of the revolving head. Fig. 9 is a section across the cam-plate shown in Fig. 7 upon the line a; Fig. 10 is a view in vertical section, en-

larged, to show the relation of the breast-ing devices to the tem plet and heel when operating. Figs. 1l to 14, inclusive, are views of the top-lift carrier in different positions. Fig. 15 is asect-ion, enlarged, upon the line a' .fr of 5o Figli.l Fig. 1G is a section, enlarged, on the line y y of Fig. 13.

Fig. 17 is a section, en-

larged, on the line .e of Fig. 14. Fig. 1S is a view in horizontal section upon the line y y of Fig. land in plan of the parts below said line to show the stop1notion mechanism. 5 5 Fig. 19 is a view in elevation of a modified form of device for turning the revolvinghead.

A is the frame of the machine.

Bis the cross-head. It carries the 'revolving head C, which is rotated by mechanism essen- 6o tially like that described in the Henderson and Raymond patent, No. 317,647, although it varies in some minor features, which will be hereinafter specified. The head Bis reciprocated by means of the cranks b and pitmen b', as described in said Henderson and Raymond patent.

v D is the templet. It is stationary during the operation of the machine, but is removable from the table d. It is represented as 7o fastened in place beneath the caps d by the bolts d2; but any other means may be employed for securing it or locking it in place in a manner to permit its ready removal and the substitution of another having a different arrangement of holes.A

p E is the last or heel-support. 1t. is mounted on the vertically-movable spindle e, which is carried by the jack-post e', which is arranged to slide upon the table e2 in the ways e3. The 8o jack-post is moved vertically by a movable head or spindle e4, which is like that described in said application, is supported in a similar manner, is vertically adjustable, and is operated by the toggle e5, lever e, pivotedat,

and the cylindrical block es, having the cam'A groove e9 upon the vertical shaft F. This vertical shaft is represented as connected with the main shaft G by means of the worm-wheel g upon the main shaft and a worm-wheel g 9o upon the shaft F, which meshes with it. i may use, however, bevel-gear in lieu of the worm and wor1n-gear,if desired. The vertical shaft F carries at its upper end the camdisk H, having a camgroove h, which receives the cam-pin 7L', connected with the nail-carrier slide-plate h2, which supports at its front end the nail-carrier H. The canipin preferably is carried by a block h3, which is horizontally adjustable in relation to the roo slide-plate h2 by means of bolts h4 and slots h5, formed .in said plate. The heel-blanks are carried in the stack M and the top lifts in the stack N, and are fed therefrom respectively by the heel-blank slide and the toplift slide fn., substantially as described in said Ray mond application, although the method of operating these slides is somewhat diiferent. The heel-blanks arefed to a pocket m and are fed therefrom by the heel-blank carrier M and top lifts fed to the pocket fn and carried therefrom by the top-lift carrier N', as described in said application; but the mech- "anism for moving the plates is somewhat different and the top-lift carrier is also of an improved construction.

For moving the heel-blank and top-1ift carriers M and N I employ a cam-disk m2 on the vertical shaft F, having the cam-groove m3, the said cam being connected with the heel-blank carrier M by the lever m", pivoted at 'm5 and connected by a link m", preferably adjustable with the cam-pin m7, the end of the link 'm6 preferably being attached to another link m8, pivoted at m9. The top-lift earrierN is connected with the cam by means of the lever m10, pivoted at m11 and connected with the cam-pin m12 by a link m13, preferably adjustable, and the inner end of this link m13 is also preferably attached to a link m14, which is pivoted atmltoastationary support. The links m and 'm13 are each made adjustable in the same manner and for the same purpose, and that is to govern the delivery position of the heeLblank and top-lift carriers, so that the position at which the heel-blanks and top lifts are delivered may be varied' in relation to the templet and the worksupport. link is made in two parts m1 m". The part m1 has a bolt m18 and the side extensions m19. The part m17 has a slot which receives the bolt, and is of a width to extend between the side extensions m19 and to be supported thereby. It is obvious. that by this means the link may be extended or shortened in length, and that this shortening and extension of the links varies the starting and stopping positions of the carriers D' N.

The heel-blank slide m and top-lift slide n are operated bv a single cam-groove n in the cam-disk N, (see Fig. 5,) which is on the vertical'snaft F. The cam is connected with the slides m n by means of the lever n3, pivoted at n, one end of which is connected with the.

slide m by a long link n.5 and the other end of which is connected with the slide n by a link ns. This lever n3 is connected with the cam n by means of the rock-lever nl, pivoted at ns, one arm of which carries a cam-pin that enters the cam-groove n and the other arm of which has a link n", which connects it with the lever n3. (See Figs et and 5.)

The jack is moved out of operative position on the completion of the nailing by means of a cam projection o upon the cam-disk O upon the verticalshaft F. (See Fig. 6.) This cam projection operates to move the jack through the link o', which is connected at o2 with the jack-plate, and the bent lever 4o3,` which is Eachl pivoted at o4 and has acam-pin o5, with which the cani o comes in contact. The lever o3 is connected with the link o by means of abolt or pin o, which entersa slot o7 in the link, so as to permit of lost motion between the two parts. This is for the purpose of allowing the jack to be moved into position by hand instead of automatically, although by making a cam-groove of proper shape instead of the cam projection o the last can be drawn automatically into place.

The stop-motion, which is similar to that described in the said Raymond application, is permitted to be operated by the movement of a notch ed cam P, which maintains the dri ving-disk P and the driven disk P2 in contact during the operation of the machine. This cam P, instead of being rotated, is reciprocated to move the notch for the reception of the pin p of the clutch-lever p into and out of position by means of the rock-shaft p2, (see Fig. 2,) which carries a cam-pin p3, which bears upon the edge cam p, which has a notch arranged to receive it. The pin is held in Contact with the edge of the cam and drawn into the notch by a spring p5. (See Fig. 2.) This cam p4 is not fastened directly to the shaft F, but is bolted to the cylinder-cam e8 by means of bolts passing through suitable slots formed in the cam-disk, which permit its partial rotation for the purposes of adjustment of the cam-disk upon the cylinder-cam, so that the position of the stop-notch in the cam maybe varied to stop the machine at any desired time, because it is obvious that the machine will run until this notch is brought into position to permit the rock-shaft to be moved to turn the cam P and release the clutch-lever p', and that hy turning this cam p4 the position ot' this notch in relation to the shaft F and the cams thereon may be varied to any required degree. The crank-shaft is connected with the driving-shaft G, as described in said Henderson and Raymond patent. The revolving head C has an arm c, carrying a block supporting a gang or group of awls c', an arm c2, which carries a block supporting a gang or group of drivers c3, an arm c4, which has a flat face and which is of a length to strike or come in contact with the upper surfaceof the templet upon its downward movement, and an arm ci", which carries the breasting-knives c.

'l'he templet D is laid out as specified in another Raymond application of even datethat is, the holes therein are located from the hreasting-line of the finished heel. This permits the breasting-knife to be placed in a permanent position on its arm-that is, it needs Ano horizontal adjustment, but is arranged so as to be moved downward immediately in front of the face of the templet and closely to it, so that it breasts the edge of the heel upon a line substantially or very nearly in continuation of the front of the face of the templet. This construction is essential, because the templet is not movable, as specified in said Raymond IOO IIO

46m-1a e application first referred to. Consequently the heel-blank must be so located as to expose the section of the front edge which is to be removed in breasting. This enables me also to use the top-lift and heel-blank lcarrier especially constructed and devised to feed the top-lift and heel-blank with especial relation to a permanent front base-line, which is the breast of a finished heel.

By using a top-lift carrier of the construction herein specified I am also enabled to make a cam of somewhat easier throw than thatdescribed in said Raymond application. I prefer that the cam for compressing the heelblank and movingit relatively to the templet G to permit the feeding of the top lift be constructed so as to provide the work-support E' with substantially these movements in relation to the templet D: First, upon the starting of the machine a quick upward movement is given to bring the heel-blank against the under surface of the templet and to partially, if not entirely, compress it before the awls enter the heel. Then if the blank has not been sufficiently compressed to continue, but somewhat slowly, the upward movement of the work-support, so that the compressing of the heel-blank shall continue during the upward movement of the awls, the feeding of the nails, and the downward movement of the drivers and the driving of the nails until it is necessary to move the work-support E downward to permit the-feeding of the top lift. This comparatively slow method of compression is advantageous, in that it enables me to construct a much more powerful cam. The cam is also constructed so as to move the work-support E rapidly downward after the nails have been driven and immediately upon the beginning of the upward movement of the drivers. T he top lift is then fed into place by the top-lift carrier beneath the templet and the work-support carrying the shoe and attached heel immediately moved upward against the same. It is notl necessary that the work-support E be moved downward to its lowest position upon this movement,

but only sufficiently to permit the movement of the top lift into position, and as soon as the top lift has been so fed the work-plate is immediately moved upward again by the cam, preferably with a somewhat rapid movement, and then with aslower or more gradual movement, it being moved upward sufficiently to compress or spank the top lift solidly upon the compressed heel-blank and also to further compress the heel, the templet being supported or reinforced, if desired, at the instant of the greatest strain by the flat-surfaced arm c, which is then at the end of its lowest movement and comes in contact with the upper surface of the templet, or thehslow pressure may be continued until the operation of the breasting-knife. The remainder of the cam is constructed, preferably, so as not to move the Work-support E downward until after the operation of the breasting device, or it may be constructed to release to a very slight extent the strain or pressure upon the heelblank, although I do not consider this necessary. This enables me to breast the heelblank under pressure. To maintain this constant pressure upon the heel-blank, it is necessary to constructthe top-lift carrier as hereinafter indicated. The remainder of the cam is constructed to release or move downward the work-support E immediately upon the completion of the downward movement of the breasting-knife to permit the heel-blank for the next shoe in order to be moved into position for attachment before the machine comes to rest. The lower end of the jackpost e may have a block or extension R, provided with an inclined under edge to facilitate the placing or moving of the post e upon the toggle-head e4.

The top-lift carrier is shown in Figs. 3 and 4t and 1l to 17, inclusive, and it is made in two sections-namely, the main section V, which slides in ways in the frame of the machine and is connected directly withthe operating-lever m10, and the section o, which is carried by the main section V, but which is movable horizontally in relation thereto. It is arranged to slide in said plate Vin suitable guides arranged therein, and it has the lingers or backward extensions o', (see Fig. 13,) which mesh with the extensions or fingers c2, extending from the said section V. The front edge V of this section v does not extend beyond the front edge of, the templet, and its object is to permit the top lift to be fed into place beneath the templet and to be held compressed with the heel-blank. against the under surface of the templet until after the operation' of the breasting device, and in the operation of placing a top lift the top-lift carrier, with a blank vunder the section t), held IOO in place against the gage n3 on the section c A of the carrier by the holding-arm c4, which is also attached to the section V of the carrier,

IIO

is moved beneath the templet to bring the v top 'lift overthe attached heel-blank. The attached heel-blank is then moved upward against the top lift with sufficient pressure to compress or spank the top lift upon the heads of the projecting nails, and at the end of this upward,v movement the section V of the carrier is immediately returned to its original position-,while the section o of the carrier remains stationary, being held by the pressure ofthe heel-,compressing cam against the under surface ofthe templet. This backward or reverse movement of the section V removes the gage o3 of the top lift from in front of the templet, so that the breasting-knife may be immediately reciprocated. (See Fig. l0.)

In order that the top lift which has beeny fed forward from the pocket by the carrier upon its outward movement may be held down during the backward movement of the section V and also of the section o, the fingers y 1:"12 are arranged to form continuations of the two sections ofthe carrier and, in fact,

make it extensible, so that while one part is movable in relation to the other the passa-ge in which the top lifts are moved forward from the pocket and held during the backward movement of both sections of the carrier is not uncovered or opened in a manner to permit the top lift being thrown up between the two'sections of the plate when apart or during the backward movement of the section t. The section o of the carrier is returned to its original position upon the outward movement of the heel-carrier l\I,the said section t then being released from pressure from the heel by the downward movement of the work-support E, the front edge of the heel-blank carrier M or a projection extending from it coming in contact with the section and moving it backward to its original position or that represented in Fig. 14.

The position which the two sections of the top-lift carrier bear to each other immediately before the feeding of a top lift is represented in Fig. ll, its position immediately at the end of the feeding of the top lift beneath the templet in Fig. 12, and upon the operation of the breasting device in Figs. 10 and 13. I do not confine myself, however, to the use of a top-lift-carrier plate of this special construction, and would say that the form of construction herein specified is especially adapted to two purposes: first, to enable the heel-blank to be held under compression continuously after the spanking of the top lift, and, second, to permit the operation of heeltrimming devices.' I have not, however, described the heel-trim ming mechanism, as I do not claim the embodiment of heel-trimming mechanism with automatic heel-nailing machines of this order. The vertical shaft F has the lower bearing f and the upper bearing f.

In operation the boot or shoe is placed upon the last or work-support E with its sole uppermost, the jack being at the forward end of the bed or table e?. It is locked thereon by any suitable centering or clamping devices, and I have represented those shown and described in said Raymond application, although I would not be understood as confining myself to them. The heel-blank is in position beneath the templet for attachment, having been moved into place at the comp1e tion of the nailing of the last heel, and it is held in position by the holding devices of the heelblank carrier, which bring its front edge or breast slightly in front of the front edge of the templet. The operator moves the jack, with the boot or shoe thereon, into a position to bring the jack-post over the toggle-head and the heel-seat of the boot or shoe beneath the heel. IIe then starts the machine, and all the subsequent operations thereof are automatic. Immediately upon starting, the heelblank is compressed against the templet by the upward movement of the heel-support op erated by its cam, and the awls immediately enter the heel-blank and prick the holes. The

heelblank carrier is then immediately withdrawn, while the heel-blank is held under compression against the templet, which compression may be increased, as above indicated. The nail-carrier, having received its load of nails from automatic nail-making devices, (not herein shown, but described in patents granted said F. F. Raymond, 2d,) is then moved forward by its cam to deliver its nails to the pricked holes. The drivers meanwhile have been brought intol position, and are reciprocated to drive the nails into the heelblank holes. Immediately upon the beginning of the upward movement of the drivers the work-support, with the attached heel, is moved downward, the top-lift carrier moved to feed or carry a top lift under the templet, and the nail-carrier is moved backward to its original position. The work-support E is immediately moved upward upon the bringing into position of the top lift, but not to so great a height as before, and the top lift applied to the protruding attaching-nails. The section V of the top-1ift carrier is then immediately withdrawn, the section fu of the carrier remaining stationary. This leaves a narrow section of the heel-blank, and also of the top lift, it' desired, extending in front of the face or front edge of the templet, which is removed to breast the heel, and the breast ing-knife is immediately moved downward to breast the heel, and upon the beginning of its upward movement the work-support E is moved downward, and then the jack is moved outward automatically,whi1e immediately following this movement the heelcarrier is moved out beneath the templet to bring the heel for attachment to the next boot or shoe into position, and at the same time moves the section t* of the top-lift carrier backward to its original position. Meanwhile a heel-blank and top lift from the heel-blank and top-lift stacks, respectively, have been fed or moved into position to be taken by their respective carriers, and the machine then automatically stops.

The device for rotating the head C is somewhat different from that described in the said Raymond' application and enables the head to be rotated easier at a greater speed than that therein described, because instead of rotating the head a quarter-revolution upon the upward throw of the cross-head I rotate it about one-eighth of a revolution upon the u pward movement and about one-eighth upon the downward movement. This mechanism comprises the disk lV, (see Figs. l and 8,) attached to the shaft w of the revolving head, which carries four cam-pins w', and the plate 102, having the stationary cam-grooves 4w3 w* w. Each of the cam-grooves w3 @U5 is connected with the central cam-groove w4 near the upper end of the central cam-groove and also about midway its length, these grooves and connections being arranged so as to permit the rotary movement of the disk. This movement is communicated to the disk by IOO l'IO

means of the inclined surfaces tu 107. Upon the upward movementof the head a cam-pin w comes in contact with the inclined surface w, which is made up in part of the surface ws of the stationary part w of the plate and in part of the surface vw10 of the latch-block w11, this latch-block being movable horizontally to and from the groove w3, so as to 'permit' the passage of a cam-pin by it upon the turning of the head on its downward movement, and it then serves by springing out into the passage or groove as a stop in preventing the pin from returning the same way, and its edge acts as a guide in causing the cam-pin to move upon the upward movement of the head along the turning surface M6. This latch-block fw is made as a solid block of metal having the inclined surface w12 and stud w13, and it is movable in a hole tu, out in the plate rc2, and is held by the plate and by a boss w15 cast thereon. A spring w16 serves to automatically return it to its original position. (See Fig. 9.) The guiding-surface 107 is formed by the surface w of the stationary block w18 and the surface w19 of the movable block w20. The movable block is mounted and made movable in the same manner as the block w11, and has an inclined surface w21, with which the ends of the cam-pins t0 are successively brought in contact upon the upward movement of the head, the surface w19 of the block forming both a stop and guide. The principal advantages arising from this construction are those which come from close and direct connections between the cams and the parts operated by them.` For instance, the cam-shaft is engaged directly by the main shaft by means of a worm and worm-wheel. The nailcarrier plate is connected directly with its operative cam, so that there is no possibility that it shall not be brought at the proper time into perfect registration with the drivers and the templet-holes. The heel-blank and toplift carriers are operated by one cam and through the medium of straight levers'only. The slides for feeding the heel-blanksand top lifts from their respective stacks Vto the carriers are operated directly from' a single operative cam. By making the templet stationary instead of movable I do away with the cam for operatingit, and by providing the vertical breast-line, which is always practically the same,'1 am enabled to make the templet-plate stationary, and at the same time to use a breasting device, which requires no f adjustment, the portion of the heel-blank which is to be removed in breasting being always located `in front of the front edge of the templet. Of coursethe templet D and nail-carrier H and the awls and drivers are removable f rom'th eir respective holding plates and arms, and they may be attached thereto to be made removable in any desired way.

It will be seen that by using a worm and worm-wheel for connecting the driving-shaft with the cam-shaft I am enabled to get a directconnection between the two shafts, and

also one that is very strong, and also one that enables me to rotate the driving `shaft at a very considerable speed relatively to that of the cam-shaft.

While I have described the heel-blank and top-lift carriers as operated by a common cam, I would say that I do not confine myself thereto, as I may use two cams instead of a single one, when desired.

It will be seen upon reference to Fig. 7 that at the end of the turning movement of the head caused by the cam-surface 107 the head is held locked `during the greater part of the remainder of its downward movement and also during its upward movement, until it is again partially turned by the cam? surface w by two of the cam -pins w', one above the center of the shaft w and one below it and the groove wiso that during the period that it is not rotated or turning, which is during the operation of the awls, drivers, and breaster, the head is double locked and guided, one pin being held and guided by the straight portion of the central groove u# above the lower connections of side grooves ws 105 therewith and the other by the portion of the central groove belowsaid connections'.

The breasting devices arel shown in Figs. 8 and '10 and comprise the block c7, which holds the knife c6, and the presser-foot csand which has a shoulder o9, against whichv the upper edge of the presser-foot rests. This block c7 is horizontally movable on the yielding block c10 for the purposes of adjustment, and is locked thereto by the screws cu. The block 010 is fastened by steady-pins c12 to the arm c5, and has a slight yielding movement in relation thereto in opposition to the spring 013.

It'will be seen that not only am I enabled by the use of a vertical shaft to bring the op- -erative cams into closer and better relation to the various parts which they operate, but I am enabled to reduce or narrow the width of the machine to a very considerable extent, thereby making quite a saving in the cost of manufacture, material, and labor.

I have shown in Figs. 3, 1l, l2, 13, and 17 a device for providing the top-lift-holding arm with tension to cause it to hold the top lift iirmly against the top-lif t gage or abutment during its outward movement, and it comprises a latch-block which is pivoted at to the section V of the carrier, has an arm which is connected with the holding-arm r4 by a spring x4, and a stud x5, which extends up through a slot in the section Vof the carrier, so that the tension device is upon the upper surface ofthe plate. This block x2 has ratchet-teeth x6, which are engaged by the locking-pawl x7, also carried by the section V. The pawl m7 has a pin x8 ext-ending upward from it, andthe latch-block has the pin x5. This pin at is so placed on the latch-bar that it comes in contact with the stop :uw near the end of the backward movement of the section V of the carrier and causes the end of the latch-bar to be thrown or moved to draw the IOO IIO

spring mi, and consequently the top-lift-holding arm 'n4 against the top lift, (sce Fig. 13,) and the pawl n? holds the latch-bar in this position. The latch-bar is released near the end of the outward movement of the carrier by a stop w11, which holds the pawland causes it by the further movement of the top-lift carrier to be withdrawn from the ratchet, and to release the latch-bar and the spring x4 and reduce the tension upon the holding-arm Au, and during the backward movement of' the section V of the carrier the parts remain in this position until the pin upon thelatcli-bar comes in contact with the stop w10 near the end of the backward movement of the plate, as above specified. This causes the holdingarm c to be drawn firmly against the end of the top lift and to clampitagainst the top-lift abutment or gage.
