On said shaft are loosely journaled the gear-wheels (Z and (lithe former meshing in the teeth of the gearwheel c and the latter meshing in the teeth of the intermediate pinion, e, that is loosely journaled on a pin or stud, c, secured to the frame of the machine. The pinion e meshes in the teeth of the gear 0 On the shaft LZ is splined the hub f, which is capable of a longitudinal adjustment on said shaft, said hub having cast in one piece with it or secured to it the conical friction-clutches f and f, the former being somewhat larger than the latter, said clutches being adapted to be forced, respectively, into or against correspondinglyshaped conical clutch-recesses d and d in the faces of the respective gears d and (Z as shown in The above described mechanism is arranged in a manner and for a purpose sub stantially as shown and described in the Patent No. 321,401. I do not claim it as my invention, and I wish to state that I do not confine myself to the precise mechanism, as other or well-known mechanism may be used for imparting a rotary motion from the shaft Z) to the shaft (Z, and to reverse the motion 011 the latter without departing from the essence of my invention.

The friction-clutches f and f" are moved longitudinally on the shaft d by means of the hand-lever 9, that is pivoted at g to the front of the frame a, and has hinged to its lower end the link 9', the rear end of which is hinged to the rock-lever g, that is supported on the fulcrum-pin g and has a forked upper end embracing thehub f between the frictionclutches f and f, in a manner and for the purpose as shown and described in said Letters Patent No. 321, f01.

h is the jack-supporting frame or bracket, that is vertically adjustable in guides a a on the front of the machine, as shown in Figs. 1, 2, and 3, said bracket having on its under side a hollow post or tube, h, within which is secured or male in one piece the nut 72/, as shown in Fig. 2. The nut h receives the upper screw-threaded end, 1", of the pressureshaft '23, which latter is guided in stationary bearings 1 Z secured to the front of the machine, and between them is splined on said shaft t' the bevel-gear t meshing in the teeth of the bevel-gear 2' secured to the front end of the clutch-shaft d, as shown in Fig. 2, in a manner and for the purpose as shown and described in the said Patent No. 321,401. When the clutch f is forced against the gear d, the jack-support h will be graduallyforced upward, and the heel of the boot that is held upon the jack and its last will be forced with a gradual pressure against the under side of the stationary nail-die holder 1;, that is held stationary during the operation of the machine, and after the heel is nailed, or after the top lift is spanked on, the clutch f is forced against the gear (Z causing the shaft (Z, bevelgears 1) F, and screw-shaft M to turn in an opposite direction, and thus cause the jacksupport to be lowered, as fully shown and described in the above-mentioned patent.

To the jack -support h is adj ustably secured the downwardlyprojecting bar H, preferably provided in its lower end with a friction-piece, H which, as the jack-support reaches its lowest position, is brought to bear against the top of the gear 1 and thus arrests the downward motion of said jack-support. 7

For the purpose of releasing the pressure on the jack and shoe after the heel has been nailed on or the top lift pressed on the projecting ends of the nails, I use in connection with the lever g areleasing device constructed as follows: The lower end of the vertical shaft 1' rests in a cup-bearing in the Vertically-adjustable block 76, that is capable of a slight vertical motion in the guides a a said block having journaled to it in its lower end a horizontal cam-shaft, 7c, adapted to rest on the top of the step or block Z, or on a hardened-steel plate, Z, secured to the top of said step, as shown in Figs. 2 and 3. The said step Z is shown as pivoted to a horizontal shaft, Z located in bearings on the frame a, and provided with regulating set-screws Z Z passing through ears on said step and screwed against the base-plate of the machine, as shown in Figs. 2, 3, and 4, for the purpose of regulating the position of said step and to secure it firmly in a vertical position; but this is not essential, as the said step may be cast in one' piece with the frame of the machine, or otherwise secured to it, without departing from the essence of my invention.

The cam-shaft has on one side a cut-away or eccentric portion, 7a", and it will thus be seen that if the shaft k is turned slightly around its axis the reduced or eccentric part of it is brought in contact with the top of the step Z, thus allowing the block 70, shaft 2', and jack-support h to drop slightly, sufficient to release the pressure between the heel and the nail-die, and after such a release is accomplished the jack-support and its connections are lowered the proper distance by forcing the clutch f" against the clutch-wheel CZ", causing the shaft d to be rotated in the desired direction and the screw-shaft 2' z" to be turned by means of the respective gears "i and 1 Such release and downward motion of the jack-support are accomplished by forcing the lever 9 toward the machine in the direction of the arrow shown in Fig. 2,the link g being for this purpose provided with a tooth or projection, g that is preferably secured in an adjustable manner to said link, as shown in Figs. 2 and 4;, and adapted to actuate a lever, 70 secured to or forming a IIO IIS

part of the cam-shaft 7;, as shown in Figs. 2, 3, and l.

A spring, 71: one end of which is secured to a lever, 712 on the cam-shaft 7s, and the other end, preferably, adj ustably secured to the frame a of the machine, as shown in Figs. 1, 3, l, and 20, tends to automatically return the lever 9, its clutch-lever g and clutches f'f to the normal position shown in Figs. 1 and 2, when the operator releases his hold on said lever g, and it does so after the lever has been released by the automatic releasing device, hereinafter to be described.

The lever 75 has on it a swell or stop projection, is, (shown in Fig. 20,) that serves as a stop against the block 1., for preventing the cam-shaft It to be turned too far around its axis when the lever g is released, and it. also acts as a stop to return the levers g and to their normal vertical position, (shown in Fig. 2,) and to li mit their automatic motions to this extent.

q is the jack, as usual, having means for securing to its upper end the last Q, that carries the shoe Q, as shown in Fig. 2. The lower part of the jack pivoted to a plate, q, that is adapted to slide in and out in guides 71 on the jaek-sup mrt 71, as shown in Figs. 1, 2, and b. The said jack is mounted in its support 7L in the same manner as shown and described in the Letters Patent No. 321301.

The automatic releasing mechanism on the lever g is ctmstructed as follows: Cast in one piece with or secured to the jack-support 71v is a plate or bracket, 72*, having a vertical perforation, h, for receiving the lever g, as shown in Figs. .1 and 10. To the side of the lever g is adjustably secured a latch, in, having an inclined o1" tapering forward end, at, as shown in Fig. 9. On the plate 71: is pivoted at n. the spring-pressed pawl n, actuated by means of a spring, n, as shown in Fig. 10. After a heel has been nailed on the shoe it is requisite to lower the jack suiliciei'itly to enable a top lift to be spanked on, and after the latter has been spanked on the jack must again be lowered to permit it and its last and shoe to be drawn forward. To lower the jack, the lever g is swung toward the machine into the position shown in Figs. 5) and 10, causing the cam-shaft ]t to release the upward pressure on thejack and the screwshaft t 1" to be automatically turned suiiiciently to lower the jack the required distance. In swinging the lever g to the position shown in Fig. 9, the latch in passes by the free end of the spring-pressed pawl 21, and the latter holds the lever g in the position shown in Fig. 9 until the jack and its support have been lowered sufficiently to cause the pawl n to sink below the lower end of the latch m, when the lever y will be automatically returned to its normal vertical position (shown in Figs. 1

inbefore mentioned, and the further downward motion of the j ack-support arrested. The latch 'm is adjustable on the lever g, so as to obtain a downward motion of the jack a little greater than the thickness of the top lift to permit the insertion of such top lift between the heel and nail-die. By means of this auto matic releasing device on the lever g the operator need not hold said lever in position during the lowering of the jack, as all that is nec 'sary for him to do is to swing the lever g to the position shown in Fig. i), where it will be held by the springpawl n until the jack is lowered the desired distance, when said lever will be automatically released and returned to its normal vertical position.

0 is a spring secured in one end to the bracket 71, its free end being adapted to be brought in contact with the lever when the latter is swung outward for the purpose of forcing the jack upward, said spring serving the purpose of autonmtically returning the lever g to its normal vertical position when the operator releases his hold on said lever after having swung it outward to its fullest extent.

0 is an adjustable setscrew on the bracket or plate 71', for limiting the outward motion of the lever g and the friction between the clutch f and its wheel (1.

r is the plungerby which the awl and driver 9 blocks are actuated, one block at a time, substantiallyin a manner as fully shown and described in the patent granted May 1, 1888, to Tyler and Merritt, No. 382,121, said plunger being movable up and down in guides in the head of the machine, and has attached to it the shaft r, the lower end of which is pivoted to the (iO]l.l'l(,Ctlllg-l0(l r, that is connected to the crank-pin I) on the shaft Z), as shown and described in United States Letters Patent No. 321,:L01.

r is a sleeve surroui'iding the shaft 1', which sleeve is firmly secured in a suitable manner to the bearings r" 1' on the frame of the machine. Directly below the bearing r is adj ustably-secured to the sleeve 1* the die holder '1'. (Shown in Figs. 1., 2, 3, 5, and The said die-holder is vertically adjustable on the sleeve r, according to the depth that the nails are to be driven, by means of a regulating set screw, i passing through the bearing 1'' and screwed into the rear part of said die-holder. Set-screws U5 1", made adjustable in scrmv-threaded perforations in the frame or head of the machine, serve as supports for the upper side of the die-holder against the upward pressure of the jack and its shoe and heel, by which all torsion and strains on the sleeve 1" are taken off and the upward press u re on the die-holder transferred directly to the frame of the machine. By means of lateral screws 1" 1", passing through screw-tln-eaded portions of the frame a, the die-holder can be adjusted laterally and with the greatest nicety, for the purpose of bringing the perforations in the nail die in lines directly below the positions of the awls or drivers.

r is a screw for securing the die-holder to the sleeve '1), as shown in Fig. 5.

w in Figs. 5 and 6is the perforated nail-die having side ribs, w w, adapted to fit and slide in correspondingly-shaped grooves o v in the recessed die-holder.

The nail-die is automatically held and locked in position in the die-holder by means of the spring-pressed pins w. (Shown in Figs. 5 and 6.)

:0 00 represent the expansive boot-clamps or shoe-centering jaws for centering and holding the rear of the boot in position while perforating or nailing the heel, which clamps are pivoted at 00' 5c in their rear ends to the block 00, which is adjustably secured to the suspension-bar 00 by means of the screw-bolt 00 going through slotted perforations in said parts 00 and as shown in Figs. 11,12, 13, and

let, such adjustment being essential for the purpose of adjusting said boot-clamps relative to the nail-die, according to variations in the heels that are to be nailed.

The inner rear ends, 00 m of the expansive boot-clamps are geared together, as shown in Figs. 11 and 14, to cause both clamps to open and close equally, and thus properly centering the boot relative to the nail-die. An expansive spring, 00 connects the boot-clamps between their fulcra and outer ends, and serves to hold the boot-clamps properly against the rear part of the boot or shoe that is being nailed.

00 is an adjustable setscrew screwed through the bar or block at, which screw rests on the bearing 12 Fig. 2, and serves as a support for the boot-clamps, so as to prevent their dropping too far below the nail-die and holder.

' 'By loosening the set-screw 00 the boot-clamp support 00 can be adjusted forward and back relative to the part 00 by means of the thumbnut m journaled in a bearing in the part 00, and adapted to receive the screw-threaded end of the spindle 00 secured in a suitable manner to the part 00 or a lateral extension thereon, as shown in Figs. 11, 12, and 14. The rear end of the part a is pivoted at 00 00 to the yoke X, (shown in Figs. 11, 12, 13, 14c, and 16,) which latter is pivoted to stationary fulcra X X, which may be secured to any stationary part of the main frame of the ma chine, such latter fulcra being arranged below the fulcra 03 00 on which the part swings, as shown in Figs. 12 and 16. It will thus be seen that by rocking the yoke X on its fulcra X X a longitudinal motion is imparted to the boot-clamps, and this is done for the purpose of moving the nailed boot or shoe heel previous to spanking the top lift on it sufficiently to cause the projecting ends of the nails to be moved out of the path of the perforations in the nail-die, so that when the top lift is put on top of the projecting ends of the nails and said top lift pressed on a solid metal portion of the nail-die shall come opposite to the places where the nails are located, which solid metal portion of the nail-die will thus serve as a rest and solid support when the top lift is spanked on, and by this arrangement I am able to dispense with the usual spanker-plate for this purpose. The yoke X is automatically turned around its fulcrum for this purpose by means of a rod, X, connected in'one end to the said yoke and in its forward end to a block on the heelclamps, as shown" in Figs. 11 and 12. The boot-clamps and their attachments are balanced by means of a counter-weight, X having a rod, X*, that is secured in an adjustable manner to the rear end of the part :0 as shown in Figs. 1.1, 12, 13, 14, and 16. A spring, X that connects the upper end of the yoke X to the rear end of the boot-clamp support 00, tends to aid in holding said bootclamps in their proper horizontal position.

The adjustable and expansive heel and toplift clamps used in connection with the bootclamps above described are constructed as follows: Above the boot-clamps is journaled, on the sleeve 1;, a hub or block, V, to which is secured a handle, V, by means of which said block or hub may be turned ninety degrees around its axis, so as to bring successively the heel and top-lift clamps in position centrally below the nail-die, the said hub being limited in its swinging motion forward and back around the sleeve 12 by means of a stop projection, ,V, secured to said hub that comes in contact with adjustable regulatingscrews V 3 V screwed through ears or projections on a collar, V, secured in an adjustable manner to the sleevev above the boot-clamps, as shown in Figs. 12, 13, and 15.

The heel and top-lift clamps are precisely alike, and one may be used interchangeably for the other, if so desired.

y y are the top-lift clamps, held together in an expansive manner by means of the spring y, said clamps being pivoted in their rear ends at y 7 to the block g which is adjustable to and from the sleeve 7; by means of a thumbscrew, y, the block 1 being guided on pins 3 3 secured to the block or hub V.

The rear meeting edges of the top-lift clamps y y are toothed, as shown at y y in Fig. 11, so as to cause them to expand and contract symmetrically when top lifts of various sizes are introduced between them and withdrawn from between them.

. The heel-clamps are arranged below the toplift clamps and at a right angle to the latter, but are otherwise constructed precisely like the toplift clamps. z z are the said heelclamps; z, their connecting-spring; z z", the fulcra 011 which they are hinged on their rear ends to the adjustable block 2 z, the regulating thumb-screw, and .2 2 the guide-pins on which the block 23 is adjustable to and from the sleeve 1;. z z are the toothed interlocking inner ends of the said heel-clamps, as shown in Figs. 11, 12, 13, and 15. The rod IIO X, leading from the yoke X, is connected to By this arrangement of heel and top lift the heel-clamp bloc .2", as shown in Figs. 11, 12, and 15, for the purpose above mentioned. clamps arranged at a right angle to each other an assistant can put in the top lift between the top-lift clai'nps while the heel is being nailed, after which the heel and top-lift clamps may be turned ninety degrees around the sleeve 2; by manipulating the handle Y, causing the top-lift clamps and the top lift held between them to come in the position previously occupied by the heel, and when said top lift is being spanked onto the heel the assistant places a heel between the heelclamps, and so on, thusfacilitating the operation of nailing the heels to the boots or shoes and spanking the top lift on without loss of time.

In Figs. 1.} and 23,5 3 are the awls, andtarc the drivers, each group of such awls and drivers being secured to the respective independ ent blocks 51 S and. T, which are laterally movable in guides in the head of the machine and guides in the lower end of the verticallymovable plunger, so that either of the said awl or driver blocks can be guided into the lower end of the plunger and locked intoposition therein during the time such block is used, in a manner as fully shown and described in the patent to Tyler and lllerritt, No. 332,121, before mentioned.

In a stationary guide, a, secured to or torming a part of the head of the machine, is guided the shipper-rod if, and to the ends of said rod are secured the tinge. u u, the inner ends of which abut against the awl-blocks S S, as shown in Fig. 23, and serve as means for reciprocating the awl and driver blocks in a like manner as shown and described in the Patent 332,121.

The shipper-rod. U is manipulated in a lateral direction for the purpose of bringing either of the awl or driver blocks directly below the plunger r, according to the work to be done, and said rod is so manipulated by the operator taking hold of a spring-pressed handle or lever, U, (shown in Figs. 1., 2, and 3,) said handle or lever being mounted on the shipper-rod U in a suitable manner, and is adapted to beloched in position on the guide a. after one of the desired awl or driver blocks has been moved into the guides on the under side of the plunger r.

\Vithin the plunger 2' is located a springpressed centering-pin, the lower end of which is autoniatically forced. into a perforation in that one of the awl or driver blocks that for the time being is connected to the plunger, as lODl'QSQl'ltOCi in Fig. 2; and I wish to state that such construction, arrangement, and mode of operaticm of the awl and driver blocks form no part oi. my present invention, it being fully shown. and described in the United States Letters Patent No. 382,121 above mentioned; but in machines of this kind it is very essential that the plunger should not be allowed to descend until the awl or drivers are moved to a position coinciding with that 01' the perforations in the nail-die below said plunger, so as to prevent the accidental breaking of such awls or drivers, and for this purpose I use a starting and safety locking and centering device which is constructed as follows:

R is a starting-lever, pivoted at R to the frame a, and havinga handle, R", in its outer end, as shown in Fig. l. R is a link or rod hinged in one end to a projection or upward extension of the lever B, and in its rear end to the clutch mechanism, hereinafter to be described, by means of which the pulley c and shaft. Z) are coupled together when the plunger '7' is to be operated. To the rear end 01. the lever B is hinged the upwardly n'oj ecting rod R the upper end of which is hinged to a lever, R that is pivoted at R to the frame of the machine, and has secured to its forward end a downwardly-proj ecting centering-pin, R (shown in Fig. 23,) which,when the handle R of the lever B is pressed downward, is caused to enter one of the centeringrecesses s s or if in the shipper-bar U, that coincides with the operating position of the awl or driver blocks, as shown in Fig. 23, and it will easily be perceived that the handle R" of the starting-lever R cannot be depressed for the purpose of starting the plunger 9' unless the shipper-bar U has been moved to such aposition relative to 'the plunger that either of the awl or driver blocks is properly centered relative to the said plunger and the perforated nail-die below itt-hat is, that the shipper-bar U must be moved laterally to such a position that one of its recesses s s t coincides with the position of the centering projection R on the lever B, as shown in Fig. 23, before the plunger 0' can be started by means of the lever B. The levers R and R are normally held by their own gravity in the non-operative positions shown in Fig. 1, the lever R being in this position supported on an adjustable set-screw, R on the frame a, which limits the downward motion of said lever R.

In connection with the starting-lever R, I use a suitable clutch mechanism for securing the pulley c and shaft 1) together when the handle R of the lever B is depressed by the operator,

In practice I prefer to use the clutch mechanism as is illustrated in Figs. 1, 2, 7, S, 17, 1S, and 19, and it is constructed as follows: On the shaft 1) is secured the pawl-carrying hub (1", to which is pivoted the pawl b by means of the pin il as shown in Figs. 2, 7, and 8. The pawl U is automatically forced outward by the influence of a spring, (Shown in Fig. 7.) The huh 1) projects into the hub c of the pulley c, which hub has one or more segmental recesses, c c, and locking projections 0 0, preferably made of hardened steel, as shown in Figs. 7 and 8.

From the above it will be seen that whenever the pawl b is liberated it will be brought by its spring against either of the locking projections c on the hub 0 during the rotation of the pulley c, and consequently the motion of the said pulley a will be communicated to the hub 12, shaft 1), and plunger 0. In connection with the said clutch mechanism and the starting-lever R, I employ a clutch or shipper plate or bar, L, preferably made in two parts, one of which is adjustably secured to the other, as shown in Figs. 2,17, 18, and 19, which plate is hung at L to the frame of the machine, and is pivoted at L to the rod R as shown in Fig. 1. To the lower end of the plate or bar L is secured an adjustable set-screw, L which normally serves as a stop against the head of the pin N, on which the pawl 13 is pivoted, so as to cause the shaft Z) to be stopped when the plunger 0" is in its highest position, as shown in Figs. 1 and 2.

In the lower end of the shipper-plate L is an inclined projection, L*, which, during the normal position of the lever L, causes the spring-pressed pawl 17 to be pressed inward and liberates it from the locking projections c on the hub of the pulley 0, thus permitting a free rotation of the latter without imparting a rotary motion to the shaft 1').

To start the shaft 1), it is only necessary to depress the handle R, when the plate or bar L is swung away from the pulley c, the setscrew L is liberated from the pin b and the pawl b is liberated from the inclined projection L on the plate L, causing the spring (7 to force the pawl b outward to the position Shown in Fig. 7, when, as the pulley c rotates, one of its projections 0 will be brought in contact with said expanded pawl b and thus cause the rotary motion of the pulley c to be communicated to the hub b and its shaft 7). After starting the shaft b and its connections, as above described, the operator lets go his hold on the handle R", causing the leverR and its plate L to be automatically returned to their normal position, (shown in Fig. 1,) and as the shaft 1) approaches the end of its revolution the pawl b is automatically forced inward by coming in contact with the inclined face L in the lower end of the plate L, by which the pulley c is liberated from the hub b" and its shaft Z), and the latter is brought to a standstill at the end of a complete revolution by the pin o coming in contact with the set-screw L as before mentioned, and for the purpose of preventing undue strain on the plate L a set-screw, L adjustably secured to the frame a, serves as a rest or support for the said frame, as shown in Fig. 8.

For the purpose of preventing the shaft Z) from rebounding when thus stopped at the end of its complete revolution, I secure to the rear end of said shaft 1) a cam or disk,

'13, having a tooth or projection, B, that serves as a stop against the weighted pawl B that is pivoted at B to the frame of the machine, thus causing the shaft 1) to be autoclamps.

matically and positively stopped at the end of its complete revolution, and in such a manner as to leave the plunger 0" at the upper end of its stroke, as shown in Figs. 1., 2, and 3.

The operation of the machine is as follows:

The jack is drawn outward, as shown in Fig.

2, and the shoe to be heeled is placed on the last, as shown in said figure. Aheelis placed between the heel-clamps, and the jack is moved toward the machine until the boot is stopped in its proper position by the boot- The jack is raised by pulling the lever g outward until the sole of the boot is pressed firmly against the heel and the latter against the under side of the naildie. The aWl-block is moved into the guides of the plunger and centered, as described, after which the machine.is set in operation by depressing the handle R", causing the awls to descend and to penetrate the heel, after which the plunger and awls ascend and remain stationary. The nail-die is then loaded in the usual manner, the driver-block is moved centrally below the plunger, and the machine again set in operation as before, causing the drivers to descend and to drive the nails into the heel and sole of the boot or shoe. The boot or shoe is then lowered by the mechanism, as described, and the top lift, introduced between the top-lift clamps, is swung into position below the nail-die, and the jack and shoe are forced upward as before by the means described, causing the projecting ends of the nails to be forced into the top lift resting against the solid under side of the nail-die, by which the top lift is spanked onto the heel without the need of a spanker-plate. jack is then again lowered, drawn outward, and the heeled boot or shoe removed and another placed in position 011 the last and its jack, the heel and top-lift clamps in the meantime having been swung to their original positions and a new heel introduced between the heel-clamps and swung into position below the naildie, and so on.

Having thus fully described the nature, c011- struction, and operation of my invention, I wish to secure by Letters Patent, and claim- 1.
