HEEL-NAILING MACHINE,

SPECIPICATION forming part of Reissued Letters Patent No. 10,588, dated April 28, 1885.

Original No. 232,215, dated January 10, 1832. Application for reissue filed December 4, 1883.

To all whom it may concern.-

Be it known that I, HENRY A. HENDERSON, of Lynn, in the county of Essex and State of Massachusetts, a citizen of the United States, ,5 have invented a certain new and useful ImprovementinHeel-Nailing Machines, of which the following is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part of this specification, [O in explaining its nature, in which- Figure 1 is a front elevation of my machine.

Fig. 2 is a vertical longitudinal section thereof.

Fig. 3 is a detail view representing the construetion of the last employed in connection i with thejack. Fig. 4 is an enlarged view representing the upper part or that portion of the machine carrying the awls, drivers, &c. Figs.

5, 6, 7, 8, 9, and are detail views hereinafter more fully specified.

Theinvention comprises a jack for holding and presenting the work to the nail-driving devices, an iron last of novel construction, used in connection with the jack, forsupporting the work, and nail-driving devicesconsisting of a 2 5 revolving head carrying two or three arms, as

the case may be,,one of which arms supports a gang or group of awls, the second a gang or group of drivers, and the third a device for holding the top lift of theheel. The revolving 0 head is supported by a cross-head, which is lowered or depressed by means of a crank and suitable connectingmechanism, as hereinafter described, and raised by-suitablesprings.

It also consists in a novel arrangement for feeding the nails to a position under the drivers, which, together with the templet for the 'awls, is supported independently of the crosshead, but which is adapted to be moved therewith, as hereinafter specified.

0 It further consists in various details of construction, which will hereinafter be more fully specified,

A represents the lower portion of the frame of the machine,and A a bracket for support 5 ing some of the upper working parts of the machine, which is bolted to theupper part or bed, a, of the part A.

B is a sliding carriage, which is adapted to be moved horizontall yby power, automatically or by hand, in suitable waysin or on the bedplate a,one of these waysbeingshown in Fig. 2.

N 0 means for operating the carriage by power are shown, but any of the well-known construetions may be employed for this purpose.

The carriage supports the jackstandard b, 5 which is ahollow post, and a rod or support,

If, having at its lower end a screw-rod, b and thumb-screw or wheel b is arranged within the post to be moved vertically by said screw and wheel, and carries or supports at its upper end the metallic last form or support b although it may be used to receive an ordinary iron or wooden last. The last or support b", shown and described, however, has one or two advantages over thevordinary metallic last,in that it can be used for rights and lofts, and can be adjusted to varying length-sizes. This I accomplish by making the lasts or supports in two parts, I) b, and connecting them by a spindle, b", which is fastened in'a hole in the part Z1 by a set-screw, b, or any other suitable locking mechanism. The part b is arranged to swivel or turn freely a half-revolution on the spindle b5, and it is shaped in such a manner that whenin the position shown in Fig. 3 it servesias a left last, and when turned a half it willserve as a right last.

By moving the spindle in or out in its hole of course the last or form may be shortened or lengthened, asdesired.

Suitable steps may be arranged upon the spindle for preventing the'part b from falling or turning by gravity beyond the. position which it should occupy.

The head 0, carrying the nail-driving appliances, is pivoted at c to the cross-head 0,

best shown in Fig. 4,) and has the awl-carryi'ng arm 0, the -driver-rod carrying arm c'fland thearm ciwhich supports the device for holding the lower lift of the heehor, as I shall call it hereinafter, the top lift, it being the last or upper lift applied to the heel when it is in its inverted position'upon the last.

The head is keyed to the shaft 0, and this shaft hassuitable bearings, 0 in the head 0, 5 and at its front end there is secured a'thneearmed handle, 0, (shown in Figs. 1 and2,) whereby the head maybe revolved.

Each arm. of the handle is provided with a notch, into which the catch a on the end of the lever c, pivoted at, 0 to a suitable bracket, is closed automatically by the spring 0 when the head has been revolved sufliciently to bring the notch in line with the catch.

, The head is reciprocated by means of the. rods D D, (shown in Figs. 1 and 4,) the cross-' bar D the loose connecting-rod D the crank D on the shaft (7, and the springs (Z d, the crank and connecting devices serving to depress or draw down the cross-head againstthe rod D is not attached at its lower end to the cross-bar D butis arranged to move o'rswing freely, at its lower end, and that it co'mmuni' cates motion to the cross-bar D only when it is permitted by the movement of the latch 11, as it may be called to swing in over the top of the post or protection (i which extends up wardly from the cross-bar D at its highest position, so that upon the continued revolution of the crank the connecting-rod' forces the cross bar and mechanism attached thereto downward.

It will be observed that the connecting-rod proper ends at the line X, and that. the strap-. plates X, boltedto the rod, extend below this line and straddle the bar D"; also, that the latch d and projection d on the connectingrod prevent the rod from swinging over the post so long as the latch is in its normal position, but that upon the horizontal movement of the latch out of the path of the movement of the projection the rod swings or is drawn in by the spring d, when the crank is at its highest point, and then moves down upon the post engaged with it, and forcesit andbar D and connecting devicesdownwardly.

In Fig. 1 the connecting-rod is represented as disengaged from the post and at its lowest position. The latch 61 is supported by a bar, dhwhich has a horizontal sliding movement in suitable ways at right angles to the line of revolution of thecrank, and in Fig. 2 I represcnta lever, d connecting-rod d", and spring a for giving this latch the proper movements in relation to the projection d*. The latch is quite narrow, and when at rest acts, as above stated, as an obstruction in preventing the connecting-rod engaging with the upper part of the post d holding the connecting-rod outwardly therefrom. Vhen, however, it is desired to start the machine, the lever d is drawn out and the latch moved from the path of the projection d, which, by the spring d*, with the connecting-rod D is drawn to aposition over the block d. Then, by the continued revolution of the crank, the connecting-rod is loses given a downward movement, and of course moves the'post and cross-bar D down with it. Meanwhile, the handle 01 being released, the latch a? is automatically drawn back to its original position by the spring (1 so that during the-upward movement of the projection d its side surface comes in contact with the -side surface of the latch, and the connectingrod is thereby moved off the upper surface of the post to its original position, and kept off "thereby until it is again desired to'start the machine.

"The shaft d has suitable bearings in the frame of the machine, and is revolved in any desirable manner.

E represents the gang or group of awls. They are fastened to their supporting-block c at the end-of the arm a in any desirable way, and the block is fastened to the end of the arm in any suitable manner. In Fig. 2 they are represented in a position to be immediately driven. e represents the templet, which is provided'with' holes a trifle larger than the size of the awls anddrivers. It is supported at the end of the plate a which is pivoted at e to the yielding post a.

The post, it will be observed, is arranged at the left hand of the machine, and the templet is swung or moved horizontally upon a vertical axis into position, and is located in that position by means ofa pin, 6 and latch 2 adapted to close automatically ovcrthe pin by spring-pressure. The templet-plate 6 also carries or supports a plate, e, which is pivoted thereto at e", and which carries atits end the nail-holder a". This nail-holder is adapted to-be swung out fromthe templet-plate,as represented in Fig. 2, and its under surface is recessed to receive a sliding plate, e This plate has alimited extent of movement, is provided with holes corresponding in number, position, and size to the holes in the templct and nail-holder, and has a downwardly-pro jecting flange, e, which, in the act of locating the nail-holder in position over the templet, comes in contact with the templet and holds the sliding plate while the nail-holder is being moved into position, there uncovering the holes in the nail-holder and causing the holes in the templet, sliding plate, and nail-holder to come in line, and consequently allow the nails to drop into the holes previously punctured in the heel.

Suitable grooves or guides on or in the under surface of thenail-holding block are arranged for receiving the sliding plate and need not further be described.

' A projection, e acts as a stop in preventing the plate from being withdrawn too farin moving it to close the holes in the nail-holder.

The templet and the nai1holdcr may be locked together by any suitable latching device.

An adjustablestop, e fixes the extent of movement of the templet-platc in an inward direction. I

.As above stated, the templet-platc is pro- IIO vided with a yielding vertical. movement. lhis is-in'iopposition to the stress of the spring a, which surrounds the rod 6, and it is moved. downwardly by the downward movement of the cross-head, as hereinafter explained, and upwardly by the spring 6 upon the upward movement of the cross-head.

The cam-lever e fastened to the lower end of the post, may be used for the purpose of looking the templet-plate in its lowest posi tion, if desired.

A stop, 1?,in connection with the adjustable bar f, forming a part of ther-cross-head frame, controls the extent oft-he upward movement of the cross-head, and the adjustable stop f limits the extent of the inward movement of the carriage B. The cross-head O has a frame, G, extending downwardly and backwardly therefrom, adapted to slide upon a portion of the bracket A, whereby the movement of the cross-head is steadied.

In operation the awls and the templet are brought to the position shown in Fig. 2, and the jack-carriage is moved to bring the heel under the templet-plate, as shown in Fig. 1. The lever d is then drawn out, and the ma chine makes one revolution and stops, driving the awls through the holes in thetempletplate inlo the heel and withdrawingthem therefrom. The operator then revolves the head a third of a revolution, bringing the drivers in 'position over the heel, substantially as shown in Fig. 4, and the nail-holder, which has been previously filled with nails, is moved into position over the templet,and the nails automatically discharged therefrom into the templet and holes formed in the heel. This stage of the operation is represented in Fig. 4. The lever'cl is then again drawn out, the machine goes through one revolution, the drivers descend through the holesin the nailholder and templet, driving the nails into the heel and soles, and clinching their ends upon themetal support. At the same time, by the contact of the driver-holder G- and the upper surface of the nail-holder, the heel is compressed as much as may be desired, the nail-holder and templet moving or yielding downwardly with the downward movement of the cross-head and drivers. The operator then revolves the head, and if atop-piece is to be spanked on he moves the arm 0 into the position be fore occupied by the awls and drivers, rcmoves the templet and nail-holder from over the heel, and the lift I-I, having been previous ly inserted in the spring-holder h, which isa spring-arm curved to embrace the side of the lift and fastenedat It to the-arm c, the le- Vcr d is again drawn out, the machine makes another revolutiomand the top piece, H, is spanked onto the remainderof the heel.

Of course I may use a head having the two arms cc" without the head a, if I desire, and

. inlieu of lifting the cross-head by spring pressure I may use a positive motion, without de parting from the spirit of this invention.

Having thus fully described my invention,
