HEEL-NAILING MACHINE.

SPECIFICATION forming part of Reissuec'i Letters Patent No. 10,589, dated April 28, 1885.

Original No. 259,687, dated June 20, 1882. Applicalion for reissue filed December 4, 1883.

of Lynn, in the county Essex and State of.

Massachusetts, a citizen of the United States, have invented a new .and useful Improvement in Heel-Nailing Machines, ofwhich the following isa full, clear, and exact description, refer-' ence'being had to the accompanying drawings, forming a part of this specification, in explain- IO ing its nature, in Which- Figure 1 is a front elevation of my machine. Fig. 2 is aview, part in vertical central section and part in elevation, lengthwise of the machine. Fig. 3 is an enlarged View of the heehreceiventemplet, and nail-holder and the manner of supporting the same, hereinafter more fully described. Fig. 4 is a vertical central section of the mechanism shown in Fig. 3, representing the construction. Fig. 5 is a plan view below the line as :20 of Fig. 1. Figs. 6, 7,

and 8 are detail views,hereinafter referred to.

Fig. 9 is a view, part in section and part in elevation, of the unshipping or stop-motion mechanism.

' This invention is an improvement upon that described in my Letters Patent No. 252,215,

dated January 10, 1882; and it relates,principally, to improvements in details of construc tion, rather than to principle.

A is the frame-work of the machine.

B is the cross-head, which is adapted to be reciprocated by means of the rods b,the crossbar b, the connecting-bar b the crank b and the springs 12*. The crank and connecting-bar 3 5 serve to depress or draw down the cross-head,

and the springs to lift it to its original position. I do not,however, confine myself to this method of reciprocating the cross-head; but may use any other suitable mechanism for so The cross head carries the sliding block or carrier C, to which is screwed or fastened in any other desirable manner the awl-holding block 0, the driver-holding block 0', and the top-lift spanker o The blockC is 4'5 moved horizontally on the cross-head to bring the-awls, drivers, and spanker successively in place,'eitherdirectly by hand or by means of a ratchet, c bolted to the side of the block,

the ratchet-wheel c, and the handwheel c andtheir connecting-shaft.

Upon the upperpartoftheblock Care formed the notches 0, into which the latch 0 which is pivoted to the cross-head and is operated by the handle 0 is adapted to shut automatic ally when the notch is brought in line therewith, thereby locking the block C to the crosshead and in a position which shall cause the awls, drivers, .or top-lift spanker to register.

In order that the sliding block C may be re turned rapidly to its original position after the 6 spanking on of the top lift of the heel, or without the latch catching in the notches, I have made the side 0 of the central notch higher than the opposite side, 0 so that the latch on the quick movement of the block does not enter the notch, but rides over it and closes on the top of the surface beyond.

The adjustable stop 0, attached to the side frame and consisting of a screw, may be used to limit the movement of the sliding block, so 0 that, upon bringing the same in contact therewith, the latch shall enter the notch for registering the awls, and there shall be no liability of the sliding block being moved past it.

Of course I may use other registering mechanism than the device described without departing from the spirit of the invention.

The awl or driver holding plates or blocks are adapted to be removed from the sliding block and others substituted for the purposes of size adjustment, and I represent in Figs. 4 and 6 the awl and driver-blocks provided with a square stud, a, which enters a square hole,

a, in their respective supporting portions of thesliding block C, and thelocking-sorew c, as a means of fastening them in a manner to permit of their quick removal and substitution. The top-lift spanker has a similar construction for the purpose of fastening, and for the purpose of vertical adjustment in relation 0 to its supporting portion of the block C it has the screws 0, which are screwed into the screw-holes c", and by means of which, upon releasing the locking-screw c, the position of the spankerin relation to the supporting-block may be changed. In lieu of this method of effecting the vertical adjustment of the spanker, I may use in place of the stud a large screw adapted to swivel in the spanker and screwing into the sliding block, and a disk or wheel :00

interposed between the spanker and the sliding block for operating the screw. "In this event simple guide-pins would be substituted for the screws 0. Any other manner of adjustment, however, may be employed, and as there are numerous ways well known to mechanics of accomplishing the object, I do not confine myself to the especial means described.

The top-lift spanker has upon its under surface a top-lift holder consisting, essentially, of a spring-clamp adapted to hold the blank by pressure upon the edges, and which is capable of adjustment to varying sizes of lifts. The clamp shown in the drawings comprises the curved spring-arms c" 0 which are fastened to the block by the bent arms or supports 0 and the adj usting-screws 0 the arms being shaped to extend upwardly upon the sides of the spanker-bloek. I prefer, however, that the arms or supports, instead of being at the front end of the springs, as represented, be near the back, as shown by the dotted lines in Fig. 8, inv order that a greater range of automatic adjustment be provided the clamp.

In addition to the spring side clamp there may be used the yielding front gage-plate, c, which is fastened to the block, and extends downwardly to a position in front of the springclamp, as shown in Fig. 8. V

In lieu of the specific construction described, any suitable lift-clamping mechanism capable of adjustment may be used.

The sliding jack D is like that described in said patent. The adjustable screw-stop d regulates the extent of its inward movement.

Upon the table A of the machine, on a line with the jack and behind it, is the bracket E, which is secured thereto in a manner to permit of its horizontal movement thereon in relation to the jack for the purposes of adj ustment. This bracket supports the yielding table E, upon which the templet E and nailholder E are arranged to slide, as hereinafter described, and a heel receiver or guide, E, for receiving the heel end of the last or other support of the boot or shoe as thejack is moved into position, whereby the heel end of the boot or shoe is caused to assume the proper position in relation to the other operative devices, and for gaging and guiding the placing of the heelblank.

The yieldingtable E has the vertical plate or standard 6, which is secured by side gibs'to the front of the bracket E in a manner to permit of its vertical movement thereon, and the table is adapted to be lowered or depressed by table carries the sliding means of the lever e, pivoted at 6 and an arm, 0 and to be automaticallylifted by the coiled spring 6, which surrounds the rod 6 and upon which rod the table moves vertically, or which is fastened to the table and moves vertically with it in a socket at its lower end. A springcatch, 6, and a latch, 6 (shown in Fig. 2,) serve tolock the table in its lowest position against the stress of the spring. The

plate 6 which is arranged'to be moved horizontally to and from the line of reciprocation of the awl in suitable ways or guides by the handle 6, and the adjustable screw-stop e limits the extent of the forward movement, and any suitable stop the the nail-'holderE. The perforated plate'c is attached to thebottom of the nail-holder, to slide thereon in closing and opening the holes therein, and by means of the projection c and the spring 6 is automatically actuated in the act of moving the nail-holder to and from its position over the templet, the spring moving the plate forward, so that the holes are cov ered, and a projection upon contact with the edge e of the templet, acting as astop in preventing the further movement of the .plate, while the nail-holder is still further moved to bring the holes in line with those in the templet. This stopping of the plate of course causes the compression of the spring, and upon the reverse movement of the nail-holder and its plate the spring moves the plate back to its original position to cover the holes.

The front of the plate or standard 6 has an opening, in whichv is the block 6", which is fastened to the bracket E and supports the heel-receiver arm 6 This arm has the slot 6 and is fastened to the block by the bolt 6 and is thereby made vertically adjustable thereon. The heel-receiver is curved to approximate the contour of the heel, and has fastened to it the yielding curved spring-arms e, which are adapted to embrace the counter of the boot or shoe, and the curved yielding spring-arms e, which are adapted to locate or assist in locating the position of the heel blank upon the heel of the boot or shoe, and in some instances to grasp and support it thereon during the nailing operation. The lower pair of these yielding arms preferably are attached to the outer ends of the holder, their inner ends being free, while the upper arms are fastened preferably at their rear end to the rear of the holder, leaving the front ends free or in a position to be adjusted horizontally in relation to the sides of the receiver by set-screws.

The start-and-stop-motion mechanism is somewhat different from that described in said patent. The connecting-bar b has the pins 22 upon its lower end, which play in vertical slots b and thereby guide the movement of the end of the bar, which is constantly reciprocating. The latch b, which forms the oper ative connection between the end of, the bar and the cross-bar, the position of which determines whether the cross-head shall bereciprocated, is moved upon its supporting or bed 11 by means of the lever b", connectingrod b and arm b. These parts really constitute a lever, the fulcrum of which is at If".

The lower end of the arm I) has the curved slot b", in which the pin b forming a part of the latch, projects. The upper part of the slot is vertical and the lower part is curved or inclinedinwardly. When thelatchisunshipped, it is in the position shown in Fig. 2. The movement of the lever b to bring the latch under the connecting-bar moves the lower end of the arm b to the position shown, in Fig. 9, and the downward movement of the latch causes the pin b, moving in the slot' b, to throw back the lever b to its original position, (see Fig. 2,) where it is locked byspring ingbehind the catchb, (see Fig; 5,) and, upon the upward movement of the latch, the pin traversing the slot from its lowest point draws the latch back from beneath the connectingrod to its original position. The lever 22 is made to bear against the edge 12 of the slot 1) in the bed-plate A, so that it automatically shuts behind the shoulder or catch b.

The work-support consists of the metal heelpiece F and the front piece, F, which is fastened to the heel-piece by a stud,f, upon which it has a slight swiveling movement.

It is intended that the machine be run by a man and a boy, and its operation is as follows: The boot or shoe is adjusted upon the worksupport and moved to the receiver and the heelblank placed in position. The templet-plate is then moved horizontally over the blank, and is then by the lever moved downward thereon and locked automatically in that position. The awls are then brought in line with the templet and the machine put in operation, making one revolution, driving the awls through the templet into the heel-blank and withdrawing them. The awls are then moved, bringing the drivers in position over the templet,and the nail-holder,which has previously been charged with nails, is moved over the templet and the nails discharged into the templet-holes and the holes in the templetblank. and the machine again set in operation, causing the drivers to drive the nails into and through the heel and into the out and in soles, clinching them upon the metallic support. The nail-drivers are then moved and the liftspanker, which has been provided with alift, is moved over the heel, the templet is withdrawn,and the machine is again set in operation and the top lift spanked on the heel.

Of course the heel-blank may be compressed during the operation of forming the holes or driving the nails, or by both, and it may be still more compressed upon applying the toplift, as the nails may be deviecs flush with the top of the heel-blank, and by further compression will still further solidify the heelblank and cause the tops of the nails to be exposed sufliciently to penetrate and hold it.

It will be noticed that the devices for holding the templet and nail-holder are arranged The nail-holder is then withdrawn,

back of the line of reciprocation-of the cross.- head, and that the templet has a direct horizontal movement upon its support, and that the nail-holder also has a direct horizontal movement. This arrangement of these parts and manner of operating them is an improve.- ment upon that described in my said Letters Patent, because it brings them where they can be more readily handled by the assistant,and where they are out of the way of the principal operator and are always in view ofthe assistant.

The lower surface of the templet may have spurs or projections 2, as represented in Fig. 4, if desired,and I find that it is a convenience to use them,because they close upon and into the upper surface of the heel-blank and hold it firmly and solidly during the driving of the awls and nails. \Vhen heel-blanks of. comparatively soft or tempered leather are used, or, in fact, any heel-blanks that will permit of it,the awls may be dispensed with and the nails driven through the heel-blank by the drivers without first puncturing it.

In my said Patent No. 252,215 I have shown and described a reciprocating crosshead carrying a gang or group of awls, a gang or group of drivers, and a lift-spanker, which are adapted to be brought successively into proper position in relation to the work, and I therefore simply claim as novel, so far as this feature of the invention is concerned, only the specific means for providing the awls, drivers, and spanker, or two of them, with horizontal movements upon the crosshead; and in this connection it'may be stated that as an equivalent for the horizontal movement of the carriage on the cross-head, as herein indicated, the work-support or jack can be moved horizontally into position under the awls, drivers, or spanker, and thelatter be stationary upon the cross-head.
