To all whom it'may concern: I Be itknown that I, ERASTUS E. VVINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts. have invented certain new and useful Improvements in Heel-Nailing Machines: and I do-hereby declare the following to be a full, clear, and exact descrip-- tion of the invention, such as will enable others skilled in the art-to which it appertains to make and use the same. The present. invention relates to machines for attachingheels to boots and shoes of that type in which the heels are secured by nails driven through the heel from the'outside and clenched into the heel seat of the insole,
and particularly to improvements in the construction. organization and modeof operation, of the heel attaching machine disclosed in Letters Patent of the United States No. 304.153, dated August 23, 1884. I
The object of the present. invention is to improve the operation of machines of this type, by rendering the same more automatic, particularly with regard to the positioning of the jack and shoe with relation to the heel compressing and nailing devices; to improve the clamping devices which center the jack and shoe, and render them automatic in operation; to' provide automatically operating means to regulate the ressure applied to the heel in accordance w1th the height of said heel. and in other particulars to be hereinafter set forth. and generally improve the operation of said machine.
To the above end, the present invent-ion consists of the devices and combinations of devices which will be hereinafter set forth and claimed. 9

I 1
In the drawings 1 represents the main frame, comprisin a vertically disposed standard supporte on a suitable base, said sha to mac ine, to brin the jac and other instrumentalities at S1151 a hei ht as to be convenient for the operator. filounted on the front of the frame so as to have a vertical re-, ciprocation on a suitable dove-tail, or other form of guide 2, is a plate or carrier 3, carrying at its upper end a bed or table4, which supports the jack carrier plate,5, the jackv carrier plate 5being preferably mounted for ahorizontal adjustment in a dove-tail guideway 6 formed in the u persurface of the.
bed or table 4:, and a' justed toward and from the standard or frame-1, by means of a screw 7 carried by a bracket 8 of the jack carrier plate 5, and engaging aithreaded aperture" (not shown); in the bed or table 4, the
. arrangement bein such that the jack carrier plate 5 ma be a 'usted to'a limited degree toward an from t e front of the frame 1, if necessary to secure the, proper positioning of the jack with relation to the heel attaching and compressing instrumentalities. The 'ack carrier plate 5 1s extended to one side 0 the bed or table 4 as shown in Fig. 1 of the drawing, and in its up er'surface is provided with preferably a dove-tail guideway 9 in which is fitted the "base of the jack carrier 10, and along which the jack carrier is ar .tion the "ack .and shoe w1ll r hereinafter, beingframe being of a height, and of a size'and support the movin' parts of the an ranged to slide for the purpose of moving the jack carrier with the jack thereon from the position shown in Fig. 1 in which posibe out of alinement wit the heel compressing and attachingdevioes, to the left as the machiue is,
shown in Fig. 1,.to 'place the. heel of'theshoe on the jack in alinement with the heel'combed or table 4 and the jack carrier 10 are, in
the machine of the drawings, secured in the following manner:-Mounted in 'suitable bearings 11 formed in the frame 1 and in a bracket 12 secured to the rear of the frame 1, is a drivin shaft 13, upon which are -mounted suita le fast and loose pulleys 14 and 15 by which-saidshaft is driven by a belt from any suitable source of power, and
said shaft 13 carries a pulley 16 fixedly se-' cured thereto. The frame 1 at its upper end or head carries a horizontally disposed bearing 17 in. which is supported to rotate the shaft 18 which operates the nail block or templet carrier, together with the nail drivers, as will be hereinafter described.
Loosely mounted upon, the shaft 18 is a pulley 19 which carries a clutch face 20 arranged to cooperate with a clutch face 21 carried by the ear 22, which gear is arranged to turn oosely on the shaft 18 and to have a sliding movement alon said shaft toward and from the pulley 19, or the purpose of connecting and dis-connecting the complementary clutch faces 20 and 21 of said pulley and gear. Thepulley 19 is arranged to be constantly driven by a belt from thebelt pulley 16, and when the complementary clutch faces 20 and 21 are coupled together, the gear 22 will. partake of the rotary movement of the pulley 19. The gear 22 meshes with and drives a pinion 23 car ried by a shaft 24 mounted in a bearing 25 a bracket '26 secured to the ported b su(p 4 I si e of the rame 1. Shaft 24 at its oppo.-
site end carries a worm 27, which meshes withand drives. a. worm gear 28,. secured near the upper end of a vertical shaft 29, arranged. to rotate in suitable bearings 30 secured to the side of the frame 1. The
shaft 29 at its lower end carries a bevel gear i -.31, which meshes with a bevel ear 32 secured to a horizontally dis ose shaft 33, arranged to rotate in suita le bearings 34 carried by the frame 1, and a vertical standard 35 projecting upwardly from the base of the frame as clearly shown in Figs. 1 and 2.
Fixed-1y mounted upon shaft 33 is a cam 36 provided with a cam groove 37 in which is fitted a camroll 38 carried by a link -39, which link is slotted as shown and embraces the shaft 33 for the purpose of being properly guided,'and 'saidlink at its opposite end is pivotally connected at 40, to one member 41 of the toggle levers 41 and 42, themember 41 of the toggle levers being pivoted at 43 to a standard 44rising from the base of the machine, the member 42 being pivotally connected at 45'to the under side of the bed or table 4. The shaft 33 also carries a cam 46 having a cam groove 47 in which is fitted a cam roll 48 carried by a lever 49 fulcrumed at 50, to the base of the machine, and which at its upper end is pivotally connected at 51 to a link 52, which link is pivotally con:
nected at 53 to the jack carrier 10, the pivotal connection being such asto permit the horizontal adjustment of the jack carrier. plate 5 which has been described (see Fig. 2).
.The arrangement just described is such, that when the clutch faces 20 and 21 are coupled together, the rotations of the pulley 19 will be communicated to the gear 22 which will in turn drive the pinion 23,- and through the shaft 24, worm 27 and worm gear 28, rotate the vertical shaft 29, which through the bevel gears 31 and 32 rotates the cam shaft 33, and the cams 36 and 46, and such cams will, by means of the lever 49, impart horizontalreciprocatio'ns to the jack carrier 10 for the purpose of moving the jack into and out of alinement with the heel compressing and attaching devices, and will by means of the toggle levers 41 and 42 I impart vertical reciprocations to the bed 4 and the jack supported thereon, and the cams 36 and 46 are so constructed that the horizontal and vertical movements of the jack. carrier will be so timed with relation to each other, that prior to the engagement of the heel seat of the boot or shoe with the .heel supported by the heel holder beneath for the purpose of attaching the heel and spanking on the top-lift, While the jack re mains beneath the heel-compressing and at taching devices, the jack will have two vertical reciprocations. to one horizontal reciprocation.
Ihave provided suitable mechanism under the control of the operator for moving the gear 22 along the shaft 18 toward the pulley 19 for the purpose of coupling the complementary clutch faces 20 and 21, and 1 lave also so constructed the clutch control ling mechanism, that after the gear 28 shall have made one complete rotation, to impart one cycle of operation to the, mechanism actuatedthereby, the gear 22 will be automat-ically moi 'cd away from the pulley 19 to y e'or fork 56, engaging a groove 57 formed 1n tliecollar or hub of the gear 22.
dis-connect the clutch faces 20 and 21, thus The shipperrod is moved longitudinally in its bearingsoi for the purpose of moving the gear22 toward the pulley 19 to couple the complementary clutch faces .20 and 21, by, means of a coiled spring 57 surrounding the rod 55, which at vone end bears against the inner face of the front bearing 54 and at the opposite end against a collar 58 fix-- edly secured to said rod. The rod 55 is.
moved in the opposite direction in its bearings 54 against the tension of spring 57 to move the gear 22 away from the pulley 19 to dis-connect'the clutch faces 20 and 21, by means of the lever which is fulcrumed at- 60 to the head of the frame 1, one end 61 of said lever engaging the fixed collar on the shaft 55, and the opposite endof the lever carrying a pin 62 which is engaged by the notched end 63 of a lever 64 fulcrumed at 65 on the head of the frame 1. The opposite end 66 of the lever 64 is arranged -to be engaged by a projection 67 carried by a,
sleeve 68 mounted on the upper end of the vertical shaft 29, whereby as the projection 67 comesin'contact w th the end 66 of the lever 64, it will rock said lever about its fulcrum, causing the forked end of the lever 64 to rock the lever 59, to move the rod against the tension of the spring 57, to disconnect the clutch faces 20 and 21. and such clutch faces will be held dis-connected so long as the projection 67 remains in engagement with the end (36 of the lever '-For the purpose of removing the projection 67' from engagement with the end 66 of the lever 64, to permit thespring 57 to move the shipper rod '55 to connect the clutch. faces 20 and 21, I' have splined the sleeve 68 to the shaft 29, as by means of a pin 69 engaging a slot 70 in said, sleeve, so that said sleeve 68 may be vertically movable on the a arm 66 of the lever 64.
The sleeve 68 is normally held depressed with the projection 67 in the plane of movemeut ofthe lever 64, to engage the ar1n66 of said lever 64, whenever the rotation of said sleeve shall bring the projection to the point shown in Fig. 3 of, the drawings, by means of a coiled spring 71 surrounding the vupper end of the shaft 29and hearing atits lower end against-the sleeve '68, and
atits upper end against an adjustable head I orscreu 7'2. threaded on the upper end of theshaft'29. The sleeve 68 is moved ver-- tically against the tension, of the spring 71 to remove the projection 67 from enga-ge-. ment with the end 66 of the lever 64, by means of a fork or-yoke- 73, provided with pins or rollers 74 engaging a groove 75 formed in the sleeve 68, such fork or yoke 73 .being fixedly secured to the-end of a. rock shaft 7 6' mgs with the clutch faces 20 and 21 dis-.
connected, the operator-by placing his foot upon the foot treadle 80 and depressing said treadlewill, bymeans of the rod 79, rock the rock shaft--76, which by means of the fork 73 will raise the sleeve 68 against the tension'of the spring 71, and remove the.
projection 67 carried by said sleeve from engagement with the arm 66 of the lever 64,
. whereupon the spring 57 will move the shipper rod 55, which by'means of the fork 56 will move the gear 2-2 toward the pulley 19 connecting .the clutch faces 20 and 21, thus imparting a rotary motion to the gear 22, which will in turn through the connecting mechanism which has been hereinbefore described, rotate the shaft 29, imparting the movements which have been described to the jack, and the operator having removed his foot from the treadle, permitting the spring 71 to depress the sleeve 68, whenever said sleeve" shall have completed one rotation with the shaft 29, the projection 67 willagain engage the arm 66 of the lever 64, and cause the lever 59 to move the shipper rod in the opposite direction against the tension of the spring5'7, dis-connecting the clutchfaces 20-and 21 and stopping the rotation of the gear 22 and-the mechanism actuated thereby.
The heel compressing and attaching instrumentalities of the machine of the drawings comprise a suitable slide 82 carrying a. horizontally disposed templet 'or nail block carrier 83, in which is fitted a templet or nail block 84 in any suitable manner, and of any suitable or preferred construction, such templet or nail block, as in machines of this general type, being provided with a series of nail receiving apertures or pockets 85. The slide 82 is arranged to have vertical reciprocations along the front of the frame 1,-it being provided with adove-tail'groove 86, which engages a dove-tail guide ST formed on the front of the frame .1. l The termedia-te or counterbalanced position'by means ofa lever 88, which is fulcrumed at 89 to the side of the frame 1, the forward end of the lever '88 engaging a pin or other suitable projection 90, on the side'of the slide'82, and its rear end beingmonnected to one end of a coiled spring 91, the opposite end of which is connected to a hook or other suitable device 92, secured to the fixed frame 1. ,After the jack and shoe have been moved upward so as to place the heel seat of the shoe in contact with the heelsupported beneath the templet or nail block84, by suitable heel holding devices, to be hereinafter descsigedfllhe slide 82 wfill belmoved down war or t 1e purpose 0 app ying pressure to the heel, compressing the lifts of such heel prior to the driving-of the attaching nails. v r
' In the present machine, I have provided suitable mechanism for imparting ,the heel compressing movement to the templet or nail block, constructed'and arranged 'so that form whether such heels'be high or low, and this adjustment of the actuating mechanism is automatically secured according to the height of any given heel. The mechanism for actuating the templet-to "compress the heel and for securing the automatic adjustment of'the pressure is, in the machine of the drawings, constructed and arranged as follows Upon the forward end of the shaft 18 is an eccentric 93, which eccentric is arranged to engage and depress a plunger 94', the upper end of the plunger being preferably yoke-shaped or formed with a recess 95, as shown in Fig. '5 of the drawings, in
slide 82 is normally held-elevated in an inthe pressure applied to the heel will be uniwhich recess is fitted a wear block 96, with K which the eccentric is arranged to engage to depress the plunger '94:. The plunger 94 extends downwardly as. shown in dotted lines Fig. 4, and the lower end thereof is guided in a bearing 97 formeddn the dovetail guide 87 of the frame 1. The plunger is provided with anundercut projection 98 having an inclined face 99 (see Fig. 4 of the drawing) and the inclined face of this tion to the plunger 94 according a vertical adjustment of thertemplet 84 adjusting said templet up or down withrelaas the wedge block is moved in or out, an causing the distance from the under face of the templet and the surface of the wear block,
which engages the eccentric, to be varied,
and thus varying the compressive movement of the templet according as the heel to be compressed is high or low and securing a uniform pressure on all heels.
As has hereinbefore been described, the vertical movement of the heel seat of the shoe in contact with the heel" or top lift supported beneath the templet, and during this vertical movement, after the heel seat has been brou ht in contact with the heel or top lift, the urther upward movement of the 'jack will carry with it the slide and templet, and I have arranged the wedge block 101. to be moved in or out b.
the rise and fall of the templet, and pre erably by the mechanism shown in the drawings. This mechanism comprises a, bell crank lever 102 which is fulcrumed at 103 carries the stud 106 along the rod 107, said block being provided with a threaded bearing engaging a threaded portion of the rod 107, as clearly shown in Fig. 4 of the drauu ing. The opposite end of the bell crank lever 102 rests upon a fixed lug 110 projected from one side of the slide 82, so that an upward movement of said slide will rock the bell crank lever 102 to move the wedge block outward or to the right as themachine is shown in the drawing. The bell crank lever is rocked in the opposite direction by means of a spring 102*, which at one end is secured to such lever and at its opposite end to a fixed portion of the frame and thus forces the wedge block into a position beneath the plunger 94 according to the position to which the counter-balancing lever 88 moves the templet carrier. By connecting the lever 102 to the rod 107 by means of the pin and slot and recessing the end 105 of such lever, as shown in dotted lines Fig. 4, the wedge block may move downward with the templet carrier whenapplying pressure. It will thus be seen that the upward and downward movements of the slide 82 will, by'means of the bell crank lever 102 and the rod 10?, move the wed e block 101 along the upper surface of the templet carrier and such movement will jack brings the adjust the templet with relation to the plun ger 94 to raise or lower such templet according as the wedge block is moved in or out. a
From the foregoing it will be seen that after. the shoe has been placed in contact withthe heel or top-lift supported beneath the templet, a rotation of shaft 18 will, by means of the eccentric 93 and plunger. 94' and the interconnecting instrumentalities which have been described, impart a down-- ward compressive movement to the templet, and that such compressive movement Wlll be rendered uniform on all heels whether said heels be high or low. As hereinbefore described, thetemple t is provided with the usual nail receivin pockets 85, and while it is held down by t e eccentric maintaining the heel under pressure, these nails are driven from the nail pockets through the I heel and clenched in the insole. Any suitable nail driving devices may be employed, those shown in the drawingcolnprising a gang or group of nail drivers 113 supported by a plunger or cross-head 114, said crosshead being arranged to have a vertical reciprocation in a suitable guideway 115, formed in the front of the head of the machine, and this plunger 114 is reciprocated by means of a crank pin 116, carrying a block 117 fitted in a recess 118 formed in the plunger 114, which crank pin 116 is carried at the front of the eccentric 93, it being so.
located relatively to the throw of the eccentric that it will imparta downward movement to the gang or group of drivers after such eccentric has imparted the heel,
compressive movement to the templet or nail block. l
The rotation of the shaft 18 is produced by the rotations of the pulley 19 which is loose on said shaft, by means of a clutch collar 119, which is fast on the shaft 18 and which is provided with a bolt 120 fitted in arecess or'bearing in the collar 119, and nor- 'mally forced outward by means of a spring 121, seated in said recess and acting against the rear end of the bolt 120, arranged to project said bolt from the recess in the collar 119 to engage a recess 122 in the hub of the gear 22, the arrangement being such that when the bolt 120 is projected into the recess 122, the collar 119 will turn with the gear 22 and pulley 19, thus rotating the shaft 18 and actuating the heel compressing and nail driving instrumentalities. The bolt 120 is withdrawn from the recess 122 to (115-0011- nect the collar 119 to stop the rotations of the shaft 18 by means of a rod 123 arranged to slide vertically in a bearing 124 in the frame 1, and having at its upper end a beveled end or shoulder arranged to engage a complementary beveled shoulder on 120 to withdraw said bolt.
the bolt positioning and elevating instrumentahties' ranged as follows :The rod 123 is nor- In order that the shaft 18 may be rotated to actuate the heel compressing and nail driving instrumentalities in pro er time relation to the jack positioning an elevatinginstrumentalities, that is, after the jack have properly positioned the jack and raised the shoe thereon in contact with the heel supported beneath the templet, I have, in
the machine of the drawing, provided connecting mechanism, whereby after the jack has been positioned and elevated as de-' scribed, the belt 120 will be thrown into the aperture 122 to rotate the shaft 18 to impart to the heel compressing and nail drivin instrumentalities their compressing'and riving movements, and such connecting mechanism -in the machine of the drawing is armally elevated and held with its "beveled shoulder in position to engage the beveled shoulder of the'bolt 120 to Withdraw such bolt by means of a coiled spring 125which bears at one end against a'suitable step or lug 126 and at its other end against a shoulder onthe rod 123. To depress said rod against the 'tension of the spring 125, said rod is connected near its lower end to a lever 127 (see Fig.1 oft-he drawings) fulcrumed at 128 to the rear of the frame 1, and which at its outer end carries a camroll 129 resting uponand engaging a cam 130, fixed to the vertical shaft 29, the throw of the cam 130 being so positioned that after said shaft has been turned by the mechanism hereinbefore described a sutfi'cientdistance to cause the cams 36 and 46 to position and elevate the jack and bring the shoe thereon in contact with the heel supported beneath the templet, said cam 130 will rock the lever 12? and move the rod 1'23downward removing the shaft 18.

I pressing instrumentalities to seat the heel on the shoe; automatic adjusting means controlled by the relative movement of thejack and heel compressing instrumentalities in bringing the heel and shoe together, and connected mechanism, whereby after the shoe has been positioned, and the heel seated as described, the heel compressing and nail drivinginstrumentalities will be automatically actuated to compress the heel and drive the heel attaching nails to secure the In machines of this type as heretofore constructed, the 'acks have usually been provided with a jac post carrying a spindle to take in to-the socket in the last, and the shoe has been centered or clamped on the jack by clamping jaws or levers which have usually been so constructed and arranged'asto be thrown in contact with the sides of the heel end of the last by means of screw threaded rods, orother vmanually operated devices, and in such devices inasmuchas the last was positioned by the immovable pin which fitted into the last socket and therefore could have no movement with relation to its support, it required considerable careand skill on the part ofthe operator to position the jack to place the heel end of the shoe in proper alinement with the heel compressing and attaching instrumentalities. In the machine of the drawing, I have so constructed my last supporting and clamping devices, that when the jack support 10 is moved as hereinbefore described, from the position to one side of the heel compressing and nail driving instrumentalities, to a posit-ion beneath such instrumentalities, the shoe will be automatically centered with relation to the heel supported by the templet', and the compressing and attaching devices, and the clamping devices automatically actuated to clamp the last with the shoe thereon, and maintain it in proper position during the operation of attaching the heeL The mechanism wherebythis is accomplished in the machine of the drawingds as follows :-The jack support 10 (see Fig. 6) is preferably provided with a bearing 131 in which fits the stem 132 which supportsthe bed or table 133 of the ack. The stem, 132 is provided with a groove 134 in which is projected a pin 135 carried by the jack support 10 the stem 132 to have a vertical ad ustment in the jack support 10, but preventing it from turning therein. This vertical adjustment is secured by forming the stem 132 with a permit-ting coarse exterior screw thread 136, which is Y engaged by a threaded sleeve 137 which rests on the upper surface of the jack support 10, and which is provided with means, such as the handles 138, whereby the sleeve may be turned and thus impart a vertical adjust ment of the stem 132 in the jack support 10.
' 132. The table 133 therefore may be turned ted with a post 139 which is located in sub stantial vertical alinement with the heel supporting post 140 of the jack, as clearly shown in Fig. 6 of the drawing, and which fits avcylindrieal bearing 139 in the stem slightly laterally in order to adjust the heel end of the shoe for rights and lefts, according to the difference in swing between right and left shoes, and this lateral adjustment of the table 133 is limited and controlled by adjustable stops or pins 141 arranged to be positioned in holes 142 formed in the forward end of an arm 143 fixedlysecured by means of a screw or other suitable devices 144 to the reduced portion 145 of the spindle 132.
The toe support 146 may be of any usual or preferred construction, that shown in the drawing being substantially like the toe support in the jack disclosed and claimed in my pending application, Serial No. 43,592, filed January 17 1901, comprising a suitable post 147 arranged to have 'a longitudinal adjustment along a guideway formed in the upper surface of the table 133 and positioned at varying distances from the heel support according to the size of shoe being operated. upon, by means of a latch 148 pivoted at 149 to the toe support and arranged to engage notches or recesses 150 formed along one side of the table 133. The toe support proper 151 is preferably formed with ayoke to receive the forward part of the shoe and is arranged to be vertically adjusted in the post or casing 152 of the toe support, it
- being raised and lowered by means of a pmion and rack mechanism (not shown) such as disclosed in the application hereinbefo-re referred to, and controlled by the hand wheel 153 whereby the toe support 151 may be .raised and lowered, ,all as disclosed in said application. 1'
The heel supporting post 140 carries at its upper end a' block 154 which is arranged to rest loosely on the upper end-of the post 140 and upon which the comb of the last rests and over which the last is free to have a sliding movement for the purpose of properly positioning the last and the shoe on the jack as will be hereinafter described. This block 154 rests at its forward end upon a vertically adjustable support 155 which is secured to the. spindle or post 140 by means of a screw 156passing through the slot 157 in the adjustable support, the lower end of the adjustable support resting upon a cam ring 158 which may be turned by the operator for the purpose of raising or lowering the support 155 to raise or lower the forward end of the block 154.
In the present invention I have provided the jack with a back-gage or abutment against which the rear endof the last is placed when the shoe is positioned in the jack, and this stop or abutment in the machine of the drawing is carried by the upper end of a lever 159 which isfulcrumed at ing screw by means of a spiral spring'165,
which atone end engages a stud 166 carried by the arm 164 and at its other end bears against the inturned arm 167 of the lever 159.
From the foregoing, it will be noted that no matter at what point the usual spindle hole may be bored in the last, or how much said hole may vary with regard to the rear end of the last, the adjustment of the last in the jack will notbe affected, as in the present machine the last being supported by a block upon which the comb of the last rests, the said last may be freely moved by the operator over said bloclcuntil the rear or back of the heel portion thereof engages the back-stop 159, and that having once se-' cured the proper adjustment of the backstop, the throw of the jack being uniform, or, in other words, the jack being always brought to the same position beneath the heel compressing and nail driving devices,
all the shoes of a given size will be uniformly centered, not-withstanding there may be variations in the positioning of the spindle sockets in the lasts, and this I consider to be a very important feature of my invention. v
' The jack clamping mechanism consists of clamps 168 which, as shown in Fig. 7 are arranged to engage the rear end of the last,
and preferably at a point near the bottom of the last and also near the comb of the last, and these clamps are pivotally mounted by studs 169, in holders 170, which holders are provided with cylindrical shanks 171, fitted in bearings 172 and arranged to be adjusted therein to properly position the clamps 168, and in which they are secured by means of set screws 1'73 arranged to engage'with the cylindrical shanks 171. The bearings 172 are carried at the upper ends of levers 174 pivotally mounted at 175 to arms 176, the lower end ofeach of the levers 174 being connected to one end of a coiled spring 177, the coil of which surrounds a stud 178 carried'by the arm 176 and the opposite end of which issecured tosaid arm.- In the lower end of each lever 174 there is are pivotally connected with toggle levers 'levers 174 about thepivots 175 and thus adjust the clamps 168. The clamps 168 are forced in engagement with the shoe by means of the arms 176 which, at their lower ends are fixedly secured to rock shafts .181 arranged to turn in suitable bearings 182 carried by the table 133, said shafts at their opposite ends carrying cranks 183, which 184 (see Fig. 8 of the drawings). A downward movement of the toggle. levers 184 will rock the shafts 181, to throwclamps 168 in contact with the last and shoe, and an upward movement of said toggle levers will move the clamps away from the shoe. These tog le levers at their union are pivoted by a stu 188 to a vertically reciprocating plunger 185, which is forced downward to actuate said toggle levers to cause the clamps to clamp the shoe by means of a bell crank lever 186 fulcrumed to the table 133, the
: inner arm- 188 of said lever being forked clamps 168 in contact wlth the last and shoe.
and carrying blocks 189 which engage with 'recems 190 formed in the plunger 185. The
opposite end ofthe lever .186 carries a rounded head 191, to be engaged by an actuating device, to be hereinafter described, whereby said lever 186 will be rocked about itsfulcrum 187 to actuate the toggle levers 184 to rock the shafts 181 to throw the The lever 186 is rocked in the opposite direction by means of a spring 192 seated. in a recess 193 and bearing at 1 its upper. end against the arm 188 of said lever, and said spring normally acts to hold the lever in the position in which it is shown in Fig. 6 of the drawings, to maintain the clamping devices 168 open, whereby the last may be readily inserted in the 'jack. i
As hereinbefore stated, the clamps 168 are automatically actuated to grip the shoe and last as the jack is moved by the cam actuated mechanism hereinbefore described, from the position shown in Fig. 1, to a position which will place the heel end of the jack in line with the heel compressing and nail driving devices, and this automatic closing of the clamps is secured by a plate194 carried by a spring sustained plunger 195 fitted to have a sliding movement in a bearing 196 supported by a bracket 197 fixedly secured to the frame 1. The plunger 195 is'surrounded by a coiled spring 198 fitted in the hearing 196which engages at one end against I the shoulder of such plunger, and at its oposite end a inst the closed end of the bearmg. Thep ate 194 is so located that as the I 7 jack is moved to a position to place the shoe in alinement with the heel compressing and nail driving devices, the head 191 of the lever 186 will come in contact with such.
plate 194 and rock the lever 186 about its fulcrum 187 actuating the heel clamping devices to clamp the shoe, as hereinbefore described.
As hereinbefore explained, the jack and shoe will liav e two reciprocations toward and from the templet, while the jack carrier holds it beneath or in line with said templet, and in order to permit this'vertical movement, while maintaining the clamping de' vices in their clamping position, the head 191 of the lever 186 is provided with a rounded face'as shown in the drawing, and the plate 194 is elongated vertically and preferably provided with a smooth face, whereb during the vertical movement of the jac the rounded head 191 may move freelyover the face of the plate 194, while the clamps are maintained in contact with the shoe. 0
In the present machine as shown in the drawings, the heel is attached in the manner common to many machines of the prior art, that is, the securing nails are driven through the heel and clenched into. the insole of the boot or shoe, the drivers being of such a length relatively to the depth of the templet, as to drive the heel attaching nails, leaving their upper ends projecting a short distance beyond the surface of the heel blank, and thereafter the top lift is spanked on to the projecting ends of the/ heel attaching nails. In the present machine, there are provided heel b ank and top liftholders, so supported that when one of said holders shall have been moved to a position beneath" the templet, the other holder will be projected in front of the templet and turned up in convenient position for the operator to insert the heel blank ortop lift therein, according as the heel blank or top lift holder shall be in the loading position.
In Figs. 11 and'l2 of the drawing there is shown in enlarged views the preferred arrangement of mechanism for supporting and actuating the heel blank and top lift holders, such views. illustrating the heel blank holder supporting the heel beneath the templet and the top lift holder in position to position.
Pivotally mounted upon a stud 199 supported inthe under face of the templet car-.
rier, is a revolving carrier 200, which, at its opposite ends is provided with bearings 201 the. bearings 201 are shafts 208which pro- 'be supplied with a top lift, or the loading 8 ject, as. clearly shown in Fig. 12, in opposite directions from thecarrier 200. The heel bla'nk holder com prises a skeleton plate 204 out out as shown at 205, which, at its rear end is provided with bearings 206 supported on one of the shafts 203, whereby said holder may be turned about said-shaft to place it in -a horizontal position, as when supporting a heel blank beneath the templet, as shown in Figs. 11 and 12 of thedrawings, and whereby it may be turned up into the position which the top lift holder occupies as illustrated in Fig. 11. The top' lift holder:
207 consists of the usual spanking plate, and like the heel holderit is provided along its lower end with bearings 208, supported on the other shaft 203, and arranged to be turned on said shaft in a manner similar to the heel blank holder. The top lift and heel blank holders are arranged to be automatically thrown to the position which the top lift holder occupies in Fig. 11, (the load ing position), whenever the revolvingcarrier 200 shall be turned to bring said holders in front of the templet carrier 83, and for this purpose each of the shafts 203 is surrounded by a torsional coiled spring 209, one end of which is fixedly secured to the shaft, and the opposite end to one of the bearings of the heel blank and top lift holders, respectively, the tendency of the springs 209 being such as to throw said hplders when brought to the front of the templet carrier into the position which the top lift holder occupies in Fig. 11.
.In order to limit the throw of the heel holder or the top lift holder, and maintain the heel blank, as the casemay be.

them in preferably a slightly inclined position as shown in Fig. 11 of the drawing, the bracket 212 is preferably extended laterally as shown in Fig. 11 and at its rear endcarries an inclined supporting plate 217against the face of which the top lift or heel blank holder is arranged to be supported while the operator places therein the top lift or There is also provided an elastic buffer or stop, which in the machine of the drawing, consists of a lever 210 fulcrumed at 211 to the bracket 212 secured to the 1 front of the templet carrier 83, which lever is supported intermediate of its ends by a coiled spring 213, one end of which is seated'on a stud 214 carried by the bracket212, and. the other end of which engages a stud 215, carried by the lever 2 10. The opposite end of the lever is projected beyond the'spring in position to be engaged bya'stud 216 projected from the inner side of the heel blank and top From th foregoing description, it will be observed that when the parts are in the position shownin Figs. 11 and 12 of the drawattached as hereinbefore described, the top I v lift holder will be turned down against the tension of the spring 209 .in order to place 1 it in substantially a horizontal position, and the carrier 200 turned in order to move the top'lift holder beneath the templet and the heel blank holder to, the front, to the position which the top lift holder occupies, as shown in the drawing. maintaining the heel and toplift holders in a horizontal position during the turning of the carrier" 200 to place such holders beneath the temple-t and until such holders shall reach a point in front of and close to the front of the templet carrier 83, there is provided a retaining device, shown as a disk 01 fixedly secured to the stud'l99 above the carrier 200 and provided at the front with a. notch 03, permitting the studs 216 to be moved to a plane beneath the disk d, thus holding the holders down while the carrier 200 is being turned and permitting such For the purpose of holdersto be'swung up when the studs reach the notch 03.
Each of theholders is provided with suitable gripping jaws which may be of any usual'or preferred form to grip the heel blank or top lift, such jaws in the machine of the drawing being shown as substantially bell crank levers 218, pivotally secured by studs 219 to the under face of the holders, and preferably having complementary intermeshing notches and teeth 220 and 221, and being rocked about their pivots 219, by means of springs 222, interposed between their rear ends 223, whereby the forward ends of the gripping devices will engage the heel blank or top lift as the case may be.
For the purpose of maintaining the carrier 200 in position with the heel blank holder or toplift holder beneath the templet,Ihave provided'suitable locking devices which, in the machine of the drawing,consist of latches 224, carried by levers 225 pivoted, respectively, at'226- to the opposite ends of the carrier 200, and arranged to engage with a slot 227 in a locking plate 228 fixed to the front of the templet carrier 83, and said latch levers are normally held pressed upwardly to causethe latches 224 to engage the recess 227 by means of leaf springs 229, which aresecured to the carrier 200, the forward ends-engaging the latch levers 225..
The latch lev'ers are the-latches 224 from engagement with the depressed to remove slot 227 by themovement of the heel. blank 4 are. turned'down as ress the latch levers position t ran ed to be en aged by thestuds 216, carrief by said holders, whereby as the holders described, they will de- 225 and remove the atches 224 from the slot 227, after which the carrier 200 may be turned to place the heel blank holder or top. lift holder, as the casefmay be, beneath the templet, and when the carrier has been turned to the position shown'in Figs. 11 and-12, the holder which I ma then be to the front, will be automatical y turned up into a loading position, and one of the latches 224 will engage the slot 227 and maintain the holder in that position during the operation of attachingthe heel and spanking on the top lift as the case y b I r Any suitable device ma be provided for loading the'templet or nai blank with nails, that shown in the machine of the drawings coinprising the Well known skimmer 230, which, as common in such devices, is provided with a sliding plate 231, arranged to retain the nails in such skimmer. The skimmer is adjustably connected at 232 to a slotted arm 233 pivoted to the upper surface of the templet, and it is provided with a handle 234, whereby it may be turned from the osition shown in Fig. 12, in which lie eperator loads the skimmer with nails, to a position which will bring such skimmerover the tem let 84 with the holes in such skimmer, re istering with the nail pockets in the temp et. To automatic-ally slide the plate 231 to brlng its holes into register w1th the holes in the purpose of permitting skimmer to drop into t e pockets of the templet, there is provided a stop 235 adjustably secured by means of a stud and slot 236 and 237 to the upper surface of the templet carrier 83 against which the projecting end 238 of the sliding plate 231 is arthe nails in such ranged to contact to force said sliding plate on t e toe rest 151, and thetemplet having .been loaded withna-ils and the heel holder and top lift holder provided with a heel blank and top lift, and the carrier 200 moved to the position shownin Figs. 11 and 12, with the heel holder supporting the'heel beneath the templet, the operator places his the skimmer for foot u on the treadle 80 and by means of the ro 79 rocks the shaft 76, thus raising the sleeve 68 and removing the projection 67 from contact with the arm 66 of the lever 64 and permitting the spring 57 to slide the. rod 55 in its bearings, moving the gear 22 toward the pulley 19' and cou pling the clutch faces 20 and 21. The gear will now be rotated by the pulley 19 and impart a rotary movement-to the shaft 29, which by means of the beveled gears 31 and 32, will rotate the camshaft 33 causing the cam36 to move the jack from the position shown in Fi 1 to a position which will brin the hee end of the shoe in line with the eel compressing and nail driving de-- vices. This movement ofthe jack has caused the head 191 of the lever 186 to be brought in contact with the plate 194 carried by the plunger 195, and the lever 186, by the instrumentalities which havebeen hereinbefore described, will automatically throw the last clamping devices in contact with the sides of the last. After the last has been positioned and clamped as described, the cam 46 will have completed, by means of the toggle levers 41 and 42, the upward movement of the jack and shoe, brlnging the heel end of the sole of the shoe against the heel supported beneath the templet, and the contact of theshoe with such heel, will have positioned the templet carrier so as to automatically adjust the pressure applied by such tem let carrier to the heel, as has been hereinbe ore fully set forth. When the heel of the shoe has been brought in contact with the heel as described, the cam 130 on the shaft 29 will come in contact with the Y roll 129 on the lever 127, rocking said lever and withdrawing the rod 123, permitting the bolt 120 to engage the recess 122, thus coupling the collar 119 to the ear 22 and causing a rotation of the shaft 18. The rotation of the shaft 18 will, by means .of the eccentric 93 and the inter-connecting mechanism which has been hereinbef-ore described, impart a downward movement to the slide 82 of the templet carrier 83, causing the desired amount of pressure to be applied to the heel, and while the slide and templet are held down with the heel under ivers 113 which descen .gressure the crank 116 operates the nail and drive the nails out of the pockets in the tem let, through the heel and into the insole o the counter-balancing lever 88, and the cam 46 p will impart a sl-ight'downward movement to the jack carrier bed, after which the machine will stop, The operator now turns the carrier 200 to place the top lift holder beneath the templet 83 and again places his foot upon the treadle 80 when the operation of the clutches just described will spank the top lift on to the projecting ends of the nails, and the continued operation ot'the machine will cause the jack to be moved to its lowermost position, and the cam 36 will move the jack to the position shown in Fig. 1,
devices and a shoe supporting ack, movable thus releasing the last from the clamping devices, after whichv the machine will stop' with the parts in the position shown in Fig. 1, with the jack inconvenient position for theremoval of the shoe ,t-herefrom and the replacing of another shoe therein, and this completes the operation of the machine.
