To all whom, iz'; mayconcern.:

Be it known that 1,'JoHN M. HOLLADAY, a citizen of the United States, residing at Holladay,in the county of Spottsylvania and State of Virginia, have invented certain new and useful Improvements in Lasting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in shoe-lasting machines, the objects in view being to provide a machine of simple and economic construction, and. which is adapted to last shoes in an efficient expeditious manner; to provide for an automatic picking up of the leather and insertion ofthe same in the grippers; for a straining of the leather by the grippers over the last; for an application of the tacks or nails to the leather and last;` for a gathering of the leather at the toe, and for a subsequent hammering of the tacks and leather, the whole being successively accomplished by mechanical means.

Other objects and advantages of the in vention will appear in the following description, and the novel features thereof will be part-icularly pointed out in theY claims.

Referring to the drawings, Figure lis a rear elevation of the complete machine, the last being shown in position and the grippers in the position they occupy when straining-the leather over the same.

parting from the spirit of my invention or sacrificing any of the advantages that will hereinafter appear.

In the present instance I employ four posts l, arranged, preferably, in the form of a rectangle, the same bein g supported at their lower ends upon a base or sill 2, and supporting at their upper ends a crown-piece 3. These posts, it will be understood, are secured together by suitable bolts, tie-bars, and other auxiliary devices in any manner desired and notnecessary here to state. The posts support a table 4, at the center of which is located the usual opening for the accommodation of the vlast and head of the machine.

Arranged around the opening in the table andbolted at their bases thereupon is a series of Vstandards 5, Fig. 1, or a, Fig. 2, the latter being slightly altered in shape, the same having at their upper ends elongated horizontal slots 6, and in rear of the same lateral flanges or shoulders 7, through which set-screws 8 are passed.

Applied to the side of each standard 5 is a movable plate 9, and through the'same at their rear ends and entering the slots 6 of said standards are transverse pins 10, having movement in the slots 6. These pins are provided with antifriction-rollers 1l, andinterposed between said rollers and the iianges or shoulders 7 of the standards 5 are in the present instance bell-shaped springs l2. The plates 9 are provided .upon'theirl upper sides TOO at their rear ends with lateral flanges 13, (see dotted lines, Fig. 2,) which limit the upward movement of the inner ends of the plates.

To the inner end of each plate 9 there is intermediately pivoted, by means of bolts 14, the two members 15 and 16 of the grippers. Those grippers at the sides of the last are preferably arranged in pairs, or what I shall term twin grippers, while those at the toe and heel, for reasons hereinafter obvious, are single grippers.7 Each,however, hasa construction common to the other, so that similar numerals may be employed for designating similar parts. The twin gripper, as its name implies, employs two members 15 in the construction shown, so that the jaws 17 thereof diverge, but it will be obvious that these jaws may be mounted upon a single shank 18. In the present instance, however, I have shown two shanks, one for each jaw. The outer ends of the jaws are i-nwardly flanged, said flan ges being curved downward and rearward and toothed, as indicated at 19.

Upon the same pin 14 as the members 15 are pivoted are in the present instance intermediately pivoted the members 1G. Each member 16 consists of a rear shank portion 2O and a divergent j awportion 21, designed to lit down upon the jaw 19, and is toothed to correspond therewith. A flat spring 22 is secured to the shank 18 of the member 15, and at its inner or free end bears upon the member 1G in advance of the pivot-pin 14, said spring having a tendency to close the jaws 21. upon the jaws 19. The shank 18 of each opposite member 15 is, by means of a transverse pin 23, pivotally connected to the upper branch of a bail 24, each of the bails 24 having formed at its lower end a shank 25.

The outer ends of the shank 2O of the members 16 are, by means of pins 26, connected to the upper ends of similar U-shaped bails 27 which, like the bails 24, are provided at their lower sides with shanks 28, and the two shanks 25 and 28 are at their lower ends connected rigidly to their bars 29 and 30, respectively, the former bar being below the latter and having an opening in its edge, as at 3l, through which depends a lug 32, formed on the under side of the bar 30. The bar 29 has a companion lug 33, and the two are provided with lateral trunnions or pins 34, which, as shown in Fig. 1, engage grooves formed in cam-disks 35, arranged upon a power-'shaft 36a. Between the two bars 29 and 30 coiled springs 36 are interposed, and these may be relied upon for closing the members of the jaws, and in that case the springs 22 might be omitted, though I deem it best to employ them. v

The table 4 of the machine, as best shown in Fig. 2, is provided with a series of radial slots 37, the same being arranged in rear and under the flanges or feet of the bases 5. These bases are preferably pivotally bolted, as at 38, to the table, and arranged in the slots 37 are movable blocks 39. Let into each block is a spring-arm 40, the inner ends of which are upwardly disposed, as at 41, and engaged with the under sides of the bases of the standards 5, beyond their pivot-bolts 38` The tendency of these springs 40 is to maintain the standards in proper radial alinement with relation to the last, and it is intended that the standards be bolted pivotally to position, so as to have a slight swiveling movement, in order to yield and to be returned by the springs after pressure is removed therefrom. In adjusting the standards it will be seen that the blocks will slide in the slots, and therefore offer no obstruction to such adjustment.

Arranged under the opening in the table, and bolted to or made integral therewith, is a U-shaped yoke-plate 42, the same having a central opening 43 below and correspondingwith thatof the table. Arranged in the openings in the table andthe yoke-plate is the last-supporting saddle 44, the same approXimating interiorly the eXterior outline of a last, and being provided upon its interior with a horizontal flange 45. From the base of the saddle, and within the same, there rises a tubular standard 46, the same having adjacent to its upper end, and formed at diametrically opposite sides, openings 47. A short stub-shaft 48 is located in the tubular standard below the plane of the openings, and piv otally mounted upon this shaft are the opposite dogs or catches 49, whose engaging ends are designed to extend through the openings 47. Light springs 50 are interposed between the outer edges of the lower portions of the dogs and the wall of the tubular standard, the tendency of the springs being to contract the upper or engaging ends of the dogs and withdraw them from the openings 47 in the standard.

A rod 51 projects upwardly through the standard to one side of the dogs, and is provided with a laterallybeveled or V-shaped liberating cam-iinger 52, which takes between the inner edges or faces of the upper ends of the dogs, and when in position, as shown in Fig. 2, supports the dogsagainst the tendency of the springs 50 and causes their outer or engaging ends to pass through the openings 47 of the tubular standard, and hence engage with recesses 53, which are formed in the last 54. The last, it will be seen, has a tubular recess to receive the tubular standard, and the offsets or recesses 53 are formed in the wall of this recess. By elevating the rod 5l it will be seen that the springs 50 will cause the dogs to contract in a manner obvious, thus disengaging their outer ends from the recesses 53 of the last and permitting a removal of the latter. Any means may be provided for raising and lowering the rod 51 for the purpose of locking and unlocking t-he last. I

tal shafts 55 are 'journaled in their ends upon suitable bearings formed on the table, or it maybe on the yoke, and arranged upon these At opposite sides of the saddle 44 horizon- IOO IIO

Y the manner to be described.

shafts eccentrically and adapted for rotation are cam-,rollers 56, whose surfaces take under the flanges 45. Arms 57 extend outward from the rollers 56, and they are connected pivotally, as at 58, to the upper ends of a bail 59, that extends under the saddle 44 and has connected therewith a vertical operating-rod 60. Said rod may be operated by hand or foot or other means.

In Fig. 5 I have illustrated in detail a form of cutter that may be `employed in connection with my machine, and is preferably located between the sin gle grips at the toe of the last. Of course they may be located at the heel or any other point where a out is desired, but I have illustrated them in Fig. 1 as located at the toe.

Referring to Fig. 5 more particularly, it will be seen that each cutter consists of a main and

auxiliary member

61 and 62, the same being arranged side by side and pivotally connected bya pin 63. The main member at its upper end is provided with an angularly-disposed bill or blade 64, and at its lower end, below its pivot 63, is diverged to form a widened iin portion 65, which is pivotally mounted upon a suitable journal 66, supported by hangers 66a. The auxiliary member 62 `is provided at its upper end with a beveled blade 67, which is designed to operate against the blade 64 of the main member 62. The blades, it will be seen, are preferably made independentV of the members and are held in position by means of pins or screws 68, so that when impaired from use they may be replaced or sharpened. A small stop-pin 69 is located on the main member 62 below its point of pivot 63 and limits the separation of the blades. A light return-spring 70 bears against the opposite side of the member 62 and has a tendency' to separate the blades so that they are normally maintained open. A cam-block 71, having a general V shape, is arranged upon the lower portion or fin 65 of the main member immediately in advance of the lower end of the auxiliary member, and the same' has an inner curved face 7 2 and arear inclined face 73.

Pivotally supported upon a rod arranged in opposite bearings 74, secured to the posts 1, is avibratory rod or arm 75, the same having its outer or free end forked, producing the branches 76, each of which extends to the side of the iin 65 of a cutter, and is provided at its extremity with a cam-roller 77, designed to operate against the several faces of the camblock 71 to cause the operation of the cutter in Arranged upon the shaft 36 is a grooved cam-disk 78, and resting thereupon is the lower forked end 7 9 of a connecting-rod 80, whose upper end is pivoted at 81 to the vibratory lever 75, so that as theshaft 36 revolves the lever 75 is vibrated or raised and lowered through the medium of theYconnecting-rod 80.

It will be obvious that the blades maybe so arranged Vin the knives with relation to each other as to produce a V-shaped cut or'hole,

removinga portion of the stock at each operation, as may be preferred.

Pivotally mounted on a horizontal shaft 82, arranged above and at one side of the last, is a Z-shaped angular arm 83, which is normally maintained supported by means of a coiled spring 84. A pin 85 is arrangedin the free end of the arm S3, and loosely connected to said arm by means of the pin is a bar 86, which may be tilted so as to abut against a stop 87, soA that when the arm 83 is lowered the bar 86 will be in proper position with relation to the bottom of the last. A headblock 88 is arranged upon the arm 86 and is adjustable thereon by means of a set-screw 89, that passes therethrough and binds upon.

the bar. Below the headblock 88 and mounted loosely upon the bar 86 is the headplate 90, the same having a central depending tubular hub 91, provided at its lower end with an annular iiange 92, Whose upper side is grooved. Below the head-plate 90 and its tubular hub a block 93 is secured to the bar 86, and the same is at intervals notched t0 receive the inner branches of a series of bellcranked levers 94, whose lower ends at their inner sides are serrated to form jaws 95. Pivoted to the outer upper branches of these bell-cranked levers 94 are levers 96, the pivots 97 being at an intermediate point of the levers 96 and the upper ends of the latter be-4 ing inwardly disposed, forming branches 98, whose inner ends have lugs 99, that fit in the groove formed in the flange 92. ends of the levers 96 are at their outer sides toothed to form jaws 100 to correspond with the jaws 95, and the two jaws are normally maintained open by means of curved springs 101. Interposed between the under sides of the lugs 99 and the bottom of the groove formed in the flange 92 are cushions 102, preferably of rubber. Coiled springs 103 are also preferably interposed between the upper sides of the branches `98 and the under side of the head-plate 90. Journaled at one side of the head-block 88 is an inclined shaft 104, the same being provided at one end with a handle or grip 105 and at its opposite end with an eccentric disk 106, having at one side a trip-stud 107.

Pivotally supported at 108 from the crown of the framework is a curved or bow-shaped lever 109, and below this lever there is jour- The lower naled in the side of the framework opposite which the arm 83 is located a stub-shaft 110.

This stub-shaft is provided at its outerend with a crank 111 and with a loose spur-gear 112, having at its inner side or hub one member of a clutch 113. The remaining member 114 of the clutchis splined on the stub, shaft andis annularly grooved to receivethe lower bifurcated end of a bell-cranked lever 115, which, is fulcrumed at 116 and-pivotedat 117 at its opposite end vto the outer endfofv thebowed lever 109. A counter-shaft-118 is arranged above the' stub-shaft 110, and car;

ries a pulley 119 and aspur-gear 120, the latter being engaged by the -loose spur-gear 112` of the stub-shaft 110. A pulley-121 is arranged on the shaft 36, and isy connected with the pulley 119 by a belt 122.

Below the stub-shaft 110 is a rod 123 ar-4 rangedV in the framework, and upon the rod there is loosely arranged a sleeve 124, which is' provided at one end with an arm 125, which 1o is connected pivotally to the' lower end of a pitmanLrod 126, whose upper end is similarly connected to the crank 111 of the aforesaid shaft 110. 'A pair of angular hangers 127 form bearings for the counter-shaft 118, said hangers being provided at their rear sides with horizontal projecting -arms 128, the lower ends of the hangers'having hinged thereto at 129 -arms 130,*whose upper ends areslotted, as at 131. Adjustably arranged in the slots 131 are pivot-bolts 132, which pivotally connect thereto links 133. =The linksare pivotally'connected at their outer ends at 134 tothe opposite terminals of an inverted-U-shaped frame 135 at intermediate points, and above said points the two terminals of the frame are pivotally connectedto the hangers 127, as indicated at 136. The

- upper end'of this U -shaped frame is provided the terminals of the U shaped frame 135 andr the hopper.

The yhopper 143, it will be understood, is interiorly divided, so as to form a series of tracksfor the travel of the tacks,'as indicated in Fig. 6, and its face is provided with openings lat the-lower end of each track, as indicated at`144. Over each vopening `144 gravitygates 145 are located, said gates, when not otherwise influenced, closing the open ings. A pair of levers 146 are pivoted to the opposite sides ot the hopper, as best shown by dotted lines in Fig. 6, and at their inner ends are-provided with recesses 147, that loosely engage over eccentrics 148, arranged.

, on the counter-shaft 118, and located at one side of the spur-gear 120. y

Arranged upon the sleeve 124, at an angle with the arm 125,V is a pair of arms 149. RigidlyA secured in any suitable manner to thearms 149 is the tacking-plate 150. This plate has the'general con-tour of the bottom of theflast and is'providedwitha longitudinally-disposed bridge 151, having a series of holes 152, which-correspond with pairs of holes 153,v formed in the `opposite sides of the plate 150. Having their terminals passed through the holes 153 of the plate is a series of inverted-U-shaped or horseshoe-shaped hammers 154, which are rigidly -held in position by means of-screws 155, which extend throughthe sides of the plate and bear against the'terminals oft-he hammers. The upper end of each hammer is provided with a threaded shank'l, and between the bridgepiece 151 and the upper ends of the hammers coiled springs 157 are located, the same being designed to cushion the hammers in case of any abnormal shock. The hammers'154 are of vari-ous' lengths, so that their endswill all contact with the-bottom `of the last, when the hammer -is lowered upon the same, in a manner hereinafter described. `lhen ele- Vated, the position vof the'hammers is such as to bring their ends'at the terminals of the feedslots in the gripper, and it is my design to employ magnets for the hammers.

Arranged on one `of the posts'l, or it may be an independent standardat the side of the machine, isl a cam 158, the same being fixed, and above the same there is swiveled on the samevpostfor independent standard, as the case may be, a corresponding camcollar 159, having a handle 160 at one side. vFrom this upper cam there proj ectsan arm 161, atwhose outerend there is arranged a sleeve 162,'in whichloosely fits forreciprocation a stud 163, having a shoulder at' its' upper end, between which `andthe upper end of the socket a coiled spring164 is located. The stud 163 projects below the sleeve 162 and is provided at its lower endA with a stop-nut 165, between which andthe bottom of the sleeve-a spring 166 or rubber cushion may be arranged.

167 represents a hammer-arm, the same being hingedly connected at 168 to the upper end of the stud 163. The outer end 'oit' the hammer-arm 1G7Vis forked orbifurcated at 169, andthe same looselyv embraces a cam-1 shaped boss 170, which is arranged upon and revolves with ashaft 171and which may be revolved in any desired manner, and which, inthe present instance, is operated by a belt 118, -which passes over and connects two pulleys 171 and 118D, located on the

shafts

171 and 118, respectively. The inner end of the hammer-arm 167 is provided with a portion of a spherical-socket 172, which loosely fits over a sphere 173, which is axially perfo- IIO rated. A plunger-rod 174 extends through 1 the sphere, is threaded at itsV lower end to receive a nut 175, and terminates at its upper end in an enlarged head 176. Arranged on this plunger and boredv to loosely receive the same is a handle or grip 177, the upper -portion of the bore being enlarged -to receive the head 176. Secured rigidly to the' lower portion of the plunger-174 is the hammer-plate 178, the same being provided at intervals with perforations 179, as best shown in y Fig. 8, said perforations being inclined, preferably, and each havin g'loosely arranged therein the shank' portion 180, at whose lower endra hammer-head 181 is produced.

The shank.

is threaded-and receives an adj usting-nut 182, and a coiled spring 183 is arranged upon the shank between the hammer-head 181 and the hammer-.plate178- l The last is placed in the leather, the stiffener is put in position, and the whole mounti ed in the saddle, after which the rod 51 is drawn down so'as to actuate the dogs 49 and engage the last,so that the latter is locked securely in the saddle. 'Vhen this operation takes place, the grippers are in the positions shown by dotted lines in Fig. 2 of the drawings, that is, Vthe jaws are open above the edge ofthe leather,.it being understood that this operation upon the part of the jaws' is caused by means of the cams 35. The leather is held directly below the jaws by means' of guidefflanges 44a, with which the upper edge of the saddle is provided, so that it simply requires a lifting of the leather in order to bring thesame between the jaws of the several grips. The saddlelast, and the parts carried thereby and connecting the same, it will be understood, are in their raised positions at this stage, and subsequently the cams 56 are caused to, rotate through the medium of their connecting-bail 59, that is 'suitably connected so as to raise the saddle and last until the leather is in the position shown by dotted lines in Fig. A2 of the drawings.

Previous to the raising of the saddle the arm 83, carrying the pick-up mechanism, is swung down bythe attendant, who grasps the handle 105 and moves the arm against the tension of the spring 84. When the pickup mechanism has reached a point above the last and is in its lowest position, the

jaws

95 and 100 will straddle the edge of the leather, and they are in position to clamp upon the same at intervals. In order to operate the jaws, theattendant now turns the handle 105, thus operating the shaft 104, upon which it is mounted,` and causes the cam 106 to depress the head 90, forcing the latter down so as to ca'use the jaws 100, at their lower ends, to swing outward against the jaws 95, thus tightly gripping the leather. It is at this point that the operation described of raising the last takes place, and with it moves upward the pick-up, so that the leather is carried to the series of grippers. As soon as the pick-up has presented the leather to the grips .the cams 35, operating said grips, serve rst to close the jaws2lagainst t-he jaws 19, so as Ato grasp the leather, after which the companion cam operates through the medium of theV bail 24 to elevate the entire grip at its outer end and bring it to the position shown in full lines in Figs. 12 and 3.

Between the time that the grips leave their lowermost positions to assume their highest position the lever 75 has been slightly elevated, so that the several branches 7.6 thereof have caused, their cam-rollers to operate against the rear inclined faces of the cams 71, formed on the fins of the cutters, and by reason of the depression of the cams and the point ofpivot of the cutters the cuttersfas a whole, are swung inward between those 'made the rollers will have reached the upper ends of the cams, at which point it will be seen that the cutters are released and are incidentally thrown outward away from the last by means of return-springs 62a. '(See Fig. 1 of the drawings.) It is at this Vpoint that the grippers begin their inward movement so as to stretch the leather as cut tightly over the last, and it is here also, or rather in such instance, that the fingers 19, located upon the inner ends of certain grippers, serve 'their useful function.. As the grippers move inward over the last the arms19c of therockshafts 19b are caused to raise against the springs 19e, thus causing the curved fingers 19a to lower and bear against the leather, holding the out portions snugly upon the last during the driving of the tack.

The springs 12, it will be seen, serve to yieldingly press the grippers inward, the latter being free to move in the slots 6, so that all inequalities in the last, either in size or shape or stretch of leather, are compensated for and a snug iit of the leather over the last results. The retraction of the pick-up by its spring causes the lug 107, carried thereby, to contact with atrip-arm 190, that extends from one end of the bow-shaped lever 109, and thus rock the same. Such rocking motion upon the part of the lever 109 serves to raise a connecting-rod 191, whoselower end is pivoted to one end ofa latch 192. The latch is pivoted at an intermediate point, as at 193, and when thus rocked its shoulder is disengaged from the hammer-plate 17 8, before mentioned, and which it engages normally and supports when not otherwise influenced, as shown in Fig. 6. Such disengagement of the latch at this time releases the hammer, and it will be seen that when the hammer is released the latch has made at least a quarter of a rotation, so that its upper end is back of a perpendicular line, and consequently the rod 191jis elevated, the bowed lever 109 is tilted, and the clutch mechanism operated by said bowed lever and indicated at 113 and 114 is in engagement, so that also the

gears

112 and 120 rotate, as does also the shaft 118. Throughthe vmedium of the crank 111 it will be seen that the facher will be sw ung downward, the sleeve 124 rotating upon the rod 123.

tacker-is raised, it will be seen that it locks the hopper in its lowest position, as shown by lfull lines in Fig. 6, in that it abuts against the end of an adjusting screw or rod 194, that is passed through the arm 130, thus pressing IOO IIO

When the the latter backward against the tension of the spring 138. The instant, however, that the tacker starts downward the mechanism supporting the hopper, being released from pressure of the tacker, swings the hopper quickly outward, so that the parts assume, by reason of the spring 138, the position shown by dotted lines in Fig. G. The hammers of the tacker, it will be seen, each carry a tack by its head, and the points of the latter are forced into the leather and last at one stroke of the mechanism. Vhen the tacker is raised, the plate 150, coming into contact with the tail end of the latch 192, swings the lower end to the rear and the upper end forward, so that its shoulder 192 engages over the tacker-plate and relocks the same in position. Such movement upon the part of the latch disengages the clutch mechanism and arrests the motion. Such movement upon the part of the tackerplate causes it to abut against the rod or screw 194, thus returning the hopper-supporting device to the position shown in full lines in Fig. 6.

When the parts are in the position shown by dotted lines in Fig. 6, the recessed end of the bar 146 engages with the cam 148, so that during the process of tackin g the tacks within the hopper are being agitated by the vibrations of the hopper and thus caused to move down the guide or slots therein, to be subsequently attracted by the tacker when the tacker and hopper have assumed their relative positions, as shown in full lines in Fig. 6. As soon, however, as the parts have resumed their position, as shown in full lines in Fig. G, the jarring of the hopper ceases by reason of the disconnection of the bar 146 with the cam.

If, when the pick-up is elevated by its spring S4, the operator should for any reason not desire to immediately and successively apply the tacks, but, for instance, to inspect the work, he may do so by simply giving the handle 105 a slight rotation, so as to throw the lug 107 out of the pathof the liberating-rod 190 until the lug has passed by said rod. Subsequently, however, when he desires to apply the tacks he may perform the function of the lug by hand, that is, simply raise the rod 190 by hand and cause the same operation as has been described.

Having applied the tacks and the grippers having released their hold upon the leather by reason -of the action of the cams and returned to their former positions it is desirable that the leather should be subjected to a pounding or hammering, and it is at this point of the operation that the hammer disclosed in Fig. 8 is swung from its folded position within the frame to a point above the last.

In operating the hammer the handle is l grasped by the hand of the operator and held stationary so far as vertical movement is concerned, and the hammer as a whole may be moved over the shoe, so that the hammerheads will contact at all points of the leather and all portions of the latter be thussubjected to their action. The cam 170, arranged on the shaft 171, will, as will be obvious, serve to vibrate the lever 167, attached to the hammer plate, and thus the hammer -heads brought in contact with the leather. The springs interposed between the hammerheads and the plate that carries the same will serve to cushion the blows of the hammer, so as to prevent injury to them and permit of rapid work. y

The springs 12, when the grippers release their hold upon the leather, serve to throw the same forward or inward, so as to disengage the lower jaws of the grippers from under the leather and permit the grippers to retract and fall to the first position.
