Specification of Letters Patent.

Patented Mar. 31, 1914.

Original application filed September 8, 1904, Serial No. 223,795. Divided and this application filed November To (ZZZ "Lo/m it may concern Be it known that we, VILLIAM R. BAR- CLAY, a citizen of the United States of America, and Josnrn GOULDBOURN, a subject of the King of England, residing at Leicester, in the county of Leicester, England, have invented certain Improvements in Machines for Attaching Heels, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the draw ings indicating like parts in the several figures.

This invention relates to improvements 1n machines for attaching heels, heel-lifts, or heel-tips with fillers to the heels of boots and shoes and, if desired, inserting slugs therein.

In application Serial No. 223,795 filed Sept. 8, 1904, which matured into Letters Patent of the United States No. 1,011,308, on Dec. 12, 1911, and of which the present application is a division, is disclosed a machine which enables a top lift or a metal heel tip with tiller to be attached to a heel by a secondary set of nails, after the heel has been attached to the boot or shoe by a primary set of nails which may have been driven from the exterior of the boot. A machine of this type may be used to attach Louis or like heels having a minimum crosssection of considerably less area than the lifts adjacent to the heel-seat. In such cases the heels may be separated into two layers or sections, and the larger heel-seat layer be first attached by a set of nails extending over an area greater than the minimum cross-sectional area of the second layer. which is attached in its turn by a second set of nails driven within the space occupied by the nails used to attach the first or larger heel-layer. Also such a machine may be used to drive slugs while spanking or blindnailing a top-lift upon the projecting heads of the heel attaching nails previously inserted.

The present invention is in the nature of modification of certain features of the machine above mentioned, and an adaptation thereof to heeling machines of the class de scribed in Letters Patent of the. United Serial No. 658,612.

States No. 694,656, granted March 4, 1902, to B. F. Mayo, although certain features of the invention are not limited in their application to use upon the particular machine referred to.

According to this invention a movable frame is provided carrying two complete sets of vertically-sliding nail drivers below corresponding nail-holding blocks, one set to be used for the heel-attaching nails, and the other for the tip and filler nails or toplift slugs, the drivers of the two sets being parallel to each other. This frame is arranged to be moved manually in a horizontal plane so as to bring the two sets of drivers alternately over a vertically-reciprocating nail-driver plunger adapted to engage with and operate one set of the nail drivers when so positioned, and the frame is preferably so arranged that the said movements take place crosswise of the operative position of a shoe in the machine. Means may be arranged to hold the heel and the tip and filler. or top-lift in position over their respective nail-holding blocks and drivers.

A. pivoted cover-plate or detaining device may be provided which can be swung over the heeltip and filler or the top lift, after the same is in position over its nail-holder, to prevent the vibration engendered by the movement of the movable frame from displacing it from its holder or the possibility of the nails jumping up out of the nailholder through the holes in the heel-tip, and being trapped against the edge of the heel as the frame is swung over. A fixed stop on the machine engages the said detainer so that the latter does not move under the heel, but is kept back, swinging on its pivot as the tip or top lift moves under the heel.

There a top-lift is to be spanked on to the protruding heads of heel-attaching nails the pressure necessary to force the top-lift on to them is applied to the lift by the movable frame in the final portion of its rise with the plunger. If desired, slugs may be driven into such a spanked-on lift by the drivers previously referred to as allotted to the nails for nailing on tips and fillers or top-lifts.

\Vhen this invention is used in the old i'nachiues of said Letters Patent No. 694,656

the heel and top-lift carrying swing frame or plate thereof is retained and used to hold the heel, but is prevented from swinging, the top-lift carrier of the said plate not being employed when it is desired to attach to the heel a tip and filler or a top-lift with slugs.

In the accompanying drawings :Figure l is a side elevat on, partly in section, of a portion of a machine such as described in said Letters Patent No. 694:,656, modified to include features of our invention. Fig. 2 is a front elevation of parts shown in Fig. 1. Fig. 3 is a plan view of the parts shown in Figs. 1 and 2, the movable frame being in position with the heel nail-block over the plunger, as in those figures. Fig. l is a view similar to Fig. 3 but with the swinging plate removed and with the movable frame positioned with the tip nail-block over the plunger. Fig. 5 is a perspective view of the tip and filler holder detached. Fig. 6 is a perspective view of the tip-nailholder and the tip-driver-block detached. Fig. 7 is a perspective view of the tip-driver-block actuating-slide detached. Fig. 8 is a plan, and Fig. 9 is a side view of the spring-controlled swing plate detent-trip, and means according to this invention to put the trip into and out of operation, the parts being in position to allow the trip to operate. Figs. 10 and 11 are, respectively, similar views to Figs. 8 and 9, but show the parts with the trip rendered inoperative. Fig. 12 is an underside view of part of the swinging plate illustrating the means for putting the heel breast-clip out of operation, and Fig. 13 is a section on the line l3-l8 of Fig. 12. Fig. 14L is a side elevation, and Fig. 15 is a plan of the means to render the jack-raising toggle inoperative.

Like letters of reference indicate like parts in all the figures.

With reference to the said drawings, which illustrate a convenient construction for combining the invention with a heelattaching and top-lift-spanking machine of the kind described in the said Letters Patent No. 694,656:In the machine of the class described in said Letters Patent only one nail-holder and one set of nail drivers are employed and a swing frame or plate, such as D, is provided which carries, in jaws h k and D 6 respectively, a heel and a toplift, the said plate being adapted to be swung so as to place the heel and the top-lift alternately in position over the nail-holder and set of drivers operated by a reciprocating plunger. The heel is first attached, leaving the heads of the nails projecting beyond the same, the swing plate then oscillates and brings the top-lift under the attached heel on to which itis then spanked. To enable this to be doneby the same nail-holdingblock as that which is used in the driving of the heel-attaching nails and by elevation of that block to the same height and by the same means as in the heel-attaching operation, a toggle-lever arrangement C C is provided at the back of the machine to raise the boot, after the heel is attached, sufficiently to allow the top-lift to come underneath the same.

In carrying out the application of certain features of this invention to this class of machines the following changes and addi' tions are made :The nail-driving plunger is employed in conjunction with a table and a movable frame carrying two nail holders and two sets Off drivers, the movable frame being pivoted on an upward extension of the table and preferably manually operated by means of a handle, its operative position being governed by two detents attached to said handle. It is placed in the machine so that its top surface is slightly below the level of the swinging plate D aforesaid.

The tip and filler are preferably carried in a recess in a plate arranged over their nail-holder, and the heel, carried in the heelholder of the swinging plate, is at a slightly higher level, so that the tip and filler may be moved laterally into operative position beneath the attached heel without raising the latter, rendering the jack-raising movement referred to above unnecessary. Mechanism is, therefore, provided for rendering the jackraising mechanism referred to above inoperative when desired.

The heel to be attached is carried in the spring heel-clip provided in this class of machines on the swinging plate D, and, as this plate remains stationary while the improved machine is used to attach tips and fillers, mechanism is provided for throwing out of action, when desired, the means for swinging the said plate, leaving it in position with the heelholder over the nailplunger, during the whole cycle of operation of the machine. It is, therefore, necessary to insure that the holder leave a free passage for the tip when raised by the plunger, and to prevent the spring-clip forming part of the holder, from closing in under the heel when the heel-carrying plate, raised with the movable frame aforesaid, drops after the heel has been attached, as in that case the clip would get in the way of the tip when the latter was moved up for attachment to the heel. Mechanism is, therefore, provided for moving and holding the jaws of the holder a proper distance apart after the removal of the heel, and clear of the rising tip.

A is the main frame of the machine, having an overhanging portion to sustain the jack, Which may be of any suitable construction; preferably substantially as shown in the patent hereinbefore referred to. 7 The jack may be swung to place a shoe conven iently thereon or to remove the same, and

may be vertically adjusted to enable the machine to operate on heels of various heights.

Below the jack and in line therewith is a horizontal table H, having a downward extension H capable of vertical movement, but not of horizontal movement, in a bearing formed in a projection A from the main frame A. The extension H is hollow to receive a nail-driver plunger J which ex tends above the table H through a hole in the same. The top of the plunger is preferably provided with a grooved head J", screwed or otherwise secured thereon, and adapted to engage as a working fit in a slot in either a heel-tip drivers-actuating slide L or a heel drivers-actuating slide M, as hereinafter described.

The hollow portion of the extension H is greater in cross-section than the hole in the table H through which the plunger passes, a shoulder being thus formed which engages one end of a spiral spring J which surrounds the upper part of the plunger within the hollow of the extension. The other end of the spring engages a shoulder on the plunger formed by an increase in diameter in the lower portion of the plunger.

Resting on the table H is a movable frame K, shaped in plan substantially like a sector, as shown in Fig. l. The movable frame is pivotally carried on a vertical stud H forming part of an upward extension H of the table H. A handle K is provided by which the frame may be moved across the table to bring either the heel or the tip nailholder in operative position over the plunger. The handle is provided with detents K which engage catches H on the table H to lock the movable frame in its two correct operative positions, that is, with either the heel nail-holder or the tip nail-holder over the plunger, the normal position when the machine is at rest being with the heel nail-holder in that position, as shown in Fig. 3.

The front of the frame contains two vertical rectangular recesses K K each extending throughout the whole height of said frame, placed side by side and similarly located with relation to the stud H so that partial rotation of the frame in either direction will cause one recess to occupy the position previously occupied by the other.

The lower portion of each recess K K is provided with vertical guide ways K in which work nail-drivers actuating-slides, L M respectively, and nail-drivers-blocks, L M respectively. Each nail-drivers-block rests on the top of its actuating-slide so as to be raised with the latter, and is constrained to follow its downward movement by offsets L M formed on upward side extensions of the slide, which offsets prevent movement. of the block away from its slide in an upward direction while allowing the block to be readily removed from the frame. The drivers have their lower ends secured in any convenient manner in the upper sun faces of the blocks L M, while their upper ends just enter the lower ends of nail cavities l; U formed in two nail holders L M carried respectively in the upper portions of the recesses 1 K and held from vertical movement in the frame K by horizontal bearings, L M respectively, engaged in groves in the recess walls.

In the bottom of each driver-actuating slide L, M is a curved slot 0, the curves forming the sides of the slots being arcs of which the stud H is the center. Each slot opens through the side of its slide adjacent to the central line of the frame into a hole in the triangular portion of the frame lying between the recesses I K, thus forming a continuous path from the middle of one slide to the middle of the other. The slots are shaped in cross'section to form a working fit wit-h the head J of the plunger J before described, which is received in them so that the plunger J may be brought, as desired, within either of the driver-actuating slides L or M.

Cover plates K may be bolted over the faces of the frame in which the recesses are situated, but these are preferably cut away in front of the nail-driver-blocks, drivers, and nail-holders, as shown, allowing these parts to be readily changed to suit vary ing sizes of heels.

The tip and filler are carried in a suitably shaped hole in a block L shown detached in Fig. 5, which rests on the tip nail-holder L carried in the recess K of the movable frame K, the upper surface of the block L being on a level with the upper surface of the said movable frame.

The movable frame K is positioned in the machine beneath the swinging plate I) so that its upper surface is clear of the under surface of the plate, allowing the said frame to be swung beneath the plate.

The swinging plate 1), upon which are supported the heel-holder 71 ]L2 and top-lift carrier 1) e, is substantially similar to that disclosed in the construction of machine described in the before-mentioned Letters Patent No. 694,656. Instead however of being mounted on a stud in the nail-block head the plate is mounted, for a purpose hereinafter fully explained, on a pin H eccentrically carried in a brush H mounted in a bearing carried on the head of the vertical stud H which, as before described, forms part of the upward extension H of the table H. In the said Letters Patent the movements of the swinging plate D are operated and controlled in the following manner :The nail carrier 0, which delivers the nails to the heel nail-holder, is carried on an arm C free to turn on a stud C on the machine frame and having a handle (no-t shown) and a spring catch (not shown) which retains the carrier in its normal nail-receiving position until removed therefrom by the operator.

On the lower end of a stud 0 on the carrier arm is a jointed actuator or cam (Z formed of two parts united by a pin and spring, so as to permit the free end of the actuator to be turned down when required. The free end of the actuator is curved, and in the movement of the nail carrier arm C from the nail-receiving position into the nail-delivering position said end meets a roller (Z said roller being mounted on a stud 10 extending downwardly from the swinging plate D, and swings the plate into position with the heel-holder over the nail-driving plunger. The stud 10 is cut away on one side below the roller and whenever the plate D is in position so that a heel carried thereby is over the plunger ready to be attached, the stud is caught by one arm of a spring-controlled locking device or detent 0 having a tail (Z and pivoted at c on an adjustable block To release the stud 10 a trip or releasing device 18 is pivoted on one side of an arm Y secured to a portion of the main frame and is held by a spring 17 above the tail of the detent, so that as the detent rises with the plate D, its tail (Z engages a notch on the trip 18 and raising the latter, passes above it. On the following descent of the plate D the tail (Z engages an inclined surface on the trip 18, and the detent is turned, releasing the stud 10, allowing the said plate to be swung by a spring-controlled rod f into position with the top-lift over the naildriving plunger.

For the purpose of the present invention the following mechanism may be provided to place and to hold the trip 18 when desired out of action :-A fiat spring Y is fixed at one end on to the opposite side of the arm Y to that on which the trip 18 is pivoted. The free end of the spring is provided with a pin Y engaged in a hole bored through the arm Y and so positioned that when the trip 18 is in its lower position as shown in Fig. 9, the pin is pressed by the spring Y against the side of the trip. hen the trip is raised by the detent, as above described, it passes above the pin Y which, under the pressure of its spring Y, unless prevented by a device as hereinafter described, is protruded in the path of the trip, preventing its falling under the action of the spring 17 and retaining it in the position shown in Fig. 11 out of engagement with the tail (Z of the detent, dur ing any subsequent upward or downward movement of the same. The detent is consequently not turned on its downward move ment and retains the plate D in fixed position.

To enable the operator to throw the pin Y out of operation, when it is desired to spank on a top-lift and allow the plate D to be swung for this purpose, a handle Y may be pivoted on the trip-carrying arm Y The handle Y is provided with an arm Y having a wedge-shaped end Y adapted to engage, when the handle is in a vertical position, between the spring and the arm Y on which it is carried, so as to draw back the pin Y from the path of motion of the trip 18 into the position shown in Fig. 8 so that the plate D may be swung at the normal period in the cycle of operation of the machine.

It is evident that alternative devices may be employed instead of a device for throwing the trip out of action.

As before stated, the heel is held in the holder or spring-clip on the swinging plate D. This holder comprises a guideway plate 6 provided with two parallel grooves to receive the shanks respectively of the breastgage h and the back-gage if. The breastgage is provided with a suitable spring 7L which acts normally to keep the breastgage in contact with the breast of the heel. The

back-gage if is normally stationary on the plate, but has to be capable of adjustment as described and illustrated in the aforesaid Letters Patent to adapt it to heels of different sizes, this adjusting device being omitted from the drawings accompanying this specification for the sake of clearness.

It is necessary to prevent the breast-gage h from closing in under the heel when the swinging plate D, raised with the movab e frame K and table H, drops after the heel has been attached, as in that case it would get in the way between the tip and the attached heel when the tip is being moved up for attachment to the same; it is also advisable to move the back-gage to insure the allowance of clearance for the tip.

To move the back-gage 7L2 and to secure the automatic opening of the breast-gage 71 the following mechanisms may be provided: As above stated, the plate D for the purpose of this invention is mounted on pin H eccentrically carried in a bush H on which pin the plate swings in the normal operation of the machine, in the manner described in said Letters Patent No. 694,656 before referred to. The bush H has attached to its lower end a gear pinion H, which is engaged by a segment gear K formed on or attached to the movable frame K, the gear being so positioned relatively to the pinion that as the frame K is moved, after a heel has been attached, to place the tip and filler in position over the plunger the gear actuates the pinion and its attached bush to move the in H and with it the swing plate 1)" and the back-gage 72/ backward. Simultaneously with this a roller stop K on the movable frame (see Figs. 3 and l) engages with a. striking piece H on a small slide H (see Figs. l2 and 13) on the under side of the said swing plate. The slide H carries an upwardly extending detent or pawl H which engages with ratchet teeth H formed on the under surface of the shank of the spring-co-ntrolled breast-gage it, so that as the movable frame K is actuated the breastgage or clip it is thereby moved forward toward the operator and clear of the heel. A spring H draws back the slide to its normal position when the striking piece is released by the return movement of the movable-frame.

The hole in the plate D through which he pawl H" extends to engage the teeth H is so shaped that when the slide is in its nor mal pcsition, that is, out of engagement with the roller K the pawl abuts against the edge of the said hole and is held out of engagement with the teeth, thus leaving the breast-gage 71. under the normal control of its spring 71. Although the above is a preferred construction of mechanism for this purpose, it is evident that the gages or jaws may be moved apart in other ways.

In said Letters Patent No. 6%,656 the jack is raised to enable the toplift to be placed under an attached heel in a known manner by means of a walking beam and its attached toggle C C actuated by means of a pendulum lever and operative connec tions (not shown) with the nail-driving plunger in a well known manner, so as to depress the jack for the attachment of the body of the heel, and then to raise the same sutliciently to permit the after attachment of the top-lift. hen the movable block is employed to attach a tip and filler, this movement of the jack is not required and the following is a convenient device for holding the ack stationary when desired.

As shown in Figs. 1 and 15, a wedge XV is provided on the end of a curved arm V pivoted in a boss on the machine frame and provided with a handle W, the wedge and arm being so positioned that by turning the arm on its pivot the wedge may be placed, as shown in full lines in Fig. 15, between the toggle C C and the machine frame, thus preventing the breaking of the toggle and consequent raising of the ack.

As shown in Fig. ll, the wedge may be conveniently carried in horizontal guides WV".

As shown in Figs. 3 and 4: the frame K is preferably provided with a cover plate or detainer If" pivoted at L" on a stud on the frame K, so as to be swung over the heel-tip and tiller, or the top lift, when the same has been placed in position in the frame, to prevent vibration engendered by the movements of the said frame from displacing the tip and filler, or the top lift, from its holder. Such displacement might also permit the nails to be jerked up out of the nail block. Then the frame K is swung over to place the tip in operative position over the plunger an abutment L on the detainer is engaged by the swinging plate I) so that the de taincr does not move with the frame K under the heel, but is held back on its pivot as the tip moves into operative position.

\l'hen it is desired to use the machine to nail on a heel and then spank on a top-lift in the manner drscribed in said Letters Patent No. 69-l,656, the operator locks the movable frame K in the position shown in Figs. '2 and 3, withdraws the wedge V from the position shown in full lines in Figs. 14: and 1.5 into the position shown in broken lines in Fig. 15, allowing the jack to be raised and lowered by the action of the toggle C C and by means of the handle Y places the wedge-shaped end Y of the arm Y in the position shown in Figs. 8 and 9, permitting the trip 18 to act and the plate D to swing after a heel has been attached. The machine is then operated as described in the patent referred to above. lVhcn, however, it is desircd to nail on a heel and then nail on a tip and filler, or secure a toplift with slugs, the operator reverses the position of the wedge .V and handle Y, thereby locking the jack-raising toggle and the plate D, and after the heel has been attached places the tip and filler or the toplift in position over the plunger by swinging the movable frame K into the position shown in Fig. 4.
