HEEL-NAILING MACHINE.

SPECIFIGATIQK forming part of Letters Patent No. 329,951, dated November 10, 1885.

Application filed January 31, 1885.

To all whom. it may concern.-

Be it known that I, FREEBORN F. RAY- MOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Heel-NailingMachines, of which the following is a full, clear, and exact description, reference being had to the accompany ing drawings, forming a part of this specification, in explaining its nature.

It is very common in manufacturing boots and shoes to first attach the heel-blank by a gang or group of nails simultaneously driven, and to then spank on the top lift to the heads of the attaching-nails, or to other nails which have been left projecting for the purpose of receiving it, and then by hand to drive additional nails through the top lift, either for the purpose of more securely holding it in place to the heel-blank or for purposes of wear or ornamentation, or for all these purposes. This last-named nailing has always been done by hand after the removal of the boot or shoe from the attaching-machine.

It is very desirable that means should be provided whereby either holes should be made in the heel for these additional or auxiliary nails after the heel has been attached, but while it is yet in the heel-attaching machine, or that before the removal of the boot or shoe from the machine, but after the heel has been attached, the additional nails be automatically driven; and I have herein described means for accomplishing both these objects, and they comprise the employment or use of a supplemental gang or group of awls, if it is desired simply to puncture the attached heel, or an additional gang or group of drivers, if it is desired to automatically drive the additional or auxiliary nails after the heelhas been attached; and these awls or drivers are so arranged that they are brought into position for use after the operation of the heel-attaching devices, as will hereinafter be fully explained.

Referring to the drawings, Figure 1 shows in elevation and vertical section a portion of the head and jack of the National Heel-Nailing Machine with my improvement added. Fig. 2 represents a vertical cross section of the cross and revolving heads, taken through the parts which comprise my invention. Fig. 3

provement at right angle to the view of Fig. 2. It also shows in vertical section a heelblank and portion of a shoe.

I have represented the invention as applied to the well-known National Heel-Nailing Machine. In said machine the heel-blank is first placed in position upon the work, then compressed or clamped, and then pricked by the awls. The attaching-nails are then fed and driven by the drivers, and in blind-nailing the top lift applied or spanked; and these three operations are performed without removing the jack by bringing the awls, drivers, and top-lift spanker successively into operative position. r

In the present application I have represented devices for forming holes for additional top-lift nails, or for driving them, as combined with the top-lift holder and spanker.

A is the spanker-block and the top-liftholding arms, springs, or jaws, which, preferably, are like those described in the Henderson patents, Nos. 252,215 and 259,687, and application filed January 10, 1883, Serial No. 81,453, and need not further be described here. The spanker A has a dovetail projection, a, which fits into the dovetail recess a in the block B. This block is carried or supported at the end of the rod b, which fitsinto a hole, 0, in the arm 0, forming a portion of the revolving head. A spring, 0, holds the block B away from the arm 0, so that the spankerblock and block B are held outward from the head by yielding pressure,and are movable in relation to the arm 0, for the purposes hereinafter stated. The arm C also supports a number of awls or drivers. If it is intended that holes only be pricked through the top lift, then awls are employed. If it is desired to drive the nails at the same time the top lift is spanked,then the drivers are used, and awls only are requisite where the heel is made of very hard stock or is very solid. For all ordinary work the drivers will answer. The awls or drivers D pass through the slots or elongated holes b in block B and holes a in the spanker-block, and they are held by a block, 01, which is movable upon the arm 0, which may have a dovetail projection which fits into a dovetail recess thereon, by which it may be moved and be fastened in place by a screw; or it may be secured thereto in any ICO other manner. Vhichever construction is used, it must have a slot through which the post b extends.

In the operation of applying atop lift to the attached heel it will be seen that upon the reciprocation of the cross-head the top -lift holder and spanker are first brought in contact with the upper surface of the heel-blank, and that they then become substantially stationary,while the arm 0 (the head continuing to descend) compresses the spring 0. This causes the awls (if awls be used) to be driven through the top lift into the heel-blank; or, if drivers are used, to drive the nails through the top lift into the heel-blank. The block B, or its post b preferably, should. bear such relation to the arm 0 or the other part of the r'evolving head that upon substantially the completion of the downward throw of the head either the surface E should come in contact wit-h the upper surface, '6, of the post b or the under surface, 6, of the arm 0 should come in contact with the upper surface, E, of the block B, so as to give afinal positive pressure. When this last construction is used, of course the arm 0 will contain a recess or space sur rounding the post b, in which the spring is compressed in order that the two surfaces 7 may come together, and when they are together, if drivers are used instead of awls, then the ends of the drivers should be fiush with the under surface of the spanker-blo'ck. Of course, as many holes may be formed in the blocks B and A and awls and drivers used as may be desired, and the awls and drivers may be arranged in any desired relation to each other. WVhen a revolving head is used and drivers are employed, I prefer to load the device with attaching-nails when it is uppermostthat is, when the spanking-surface is presented upwardan'd the operator or boy then places upon the ends of the drivers,when in the position shown in Fig. 1, the nails which are to be driven,with their heads downward, resting on the ends of the drivers. He then places the top lift in position, its edge being held or grasped by the top-lift-hol'di'ng arms, and consequently upon the revolution of the head, so as to bring the 'spanker-surface into operative position, the nails are held from leaving the spanker-bl'ock B by the top lift; but when the cross-head is reeiprocated to spank on the top lift the top lift is first brought into position upon the heel-blank, and while held in this position the continued movement of the cross-head causes the device to be driven in and the nails 'to be driven.

In lieu of holding the nails in place by a top lift, magnets may be arranged, as described in my pending application, so as to project upon the line with the holes a forming portions of the walls thereof, and thus hold the nails in:

with nails-I have arranged a sliding nail holder and carrier block, F, adapted to be moved into position upon the support f over the spankerblock when it is in its highest position with its spanking-surface uppermost. This nail holder and carrier has a sliding bottom, f, which is automatically moved by a pin, f or in any other desirable way, when the holes are in line with the holes in the spanker-block, so that the nails may be automatically fed to the top-lift block. It will not be necessary, perhaps, to use such a plate when only two or three nails are to be driven; but if a larger number are to be driven it will be very desirable to feed them in this way. The sliding block, instead of being carried by the support attached to the cross-head, may beheld by a stationary support. Y

It will be observed that by the 0 peratio-n of this improvement the heel-bl-ank is first at,- ta'ch'ed, the attaching-nails then driven, the spanker then applied to the heel-blank, and additional nails, either for purposes of ornamentation, or for the purpose of securing the top lift in place, or-to increase the wearingsurface of the heel, are then driven automatically through the top lift, preferably nearly simultaneously with its location in place, although it may be immediately. following, and that, in lieu of driving these additional toplift nails, holes therefor only may be formed, the nail-s to be afterward inserted by hand I prefer, however, the construction whichdrives the nails as a simultaneous operation with the placing of the top lift.

Itis not necessary, in practicing this inven tion, to leave the heads of the attachingnails projecting for the reception of the top lift, as enough top-lift nails may be used to fasten the top lift to the heel-blank without the aid of the h'eel-blank-attaching nails.

I have shown the revolving head as provided with an additional spanker, H,which is adapted to be brought into position and reiciprocated after the top lift has been'attached and the top-lift nails driven.

For the insertion of large nails or slugs it is desirable, for certain classes of work, to prick or form holes in the heel-blank before they are driven, and for this purpose the heel-blank may be perforated without perforating the top lift, and this is accomplished by providing the awl-holder block with additional avvls for forming the holes in the heel-blank for the reception of these larger nails or slugs, which are afterwarddriven through the top lift, and which is either unperforate'd, or which may have been previously perforated for their reception.

Heretofore it has been common in heel-attaching machines either to drive a single gang or group of nails from the inside 'of the shoe,

as described in the patent to Salosh-insk y, No.

27,008, dated January 31, 1860; or one gang IIO from the inside of the .boot or shoe and the other from without the same, as *d'escribedand shown in patents to Jenkins, No. 31,690, dated March 12, 1861, and to Ellis, No. 41,038, dated September 22, 1863; or from without the shoe, as described in patent to Ellis and Glidden, No. 32,067, dated October 7, 1862, reissued May 20, 1873, under No. 5,413, and many other patents; but I have no knowledge of any machine organized to drive two gangs or groups of fastenings successively into a heel from without the boot or shoe, whereby the heel is first attached and a secondary or supplemental group of fastenings then driven into the attached heel through the top lift or otherwise, although I am aware that heels have been attached by heel-attaching machines organized to drive a single gang or group of fastenings from without the boot or shoe, and that the supplemental or auxiliary group of fastenings have been. driven singly by hand.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.
