H EEL-ATTACHING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 394,298, dated December 1l, 1888.

Application filed April 27, 1888. Serial No. 272,023. (No model.)

To all whom t1/my con/cern:

Be itknown that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State oli' Massachusetts, a citizen of the United States, have invented a new and useA ful Improvement in lIeelU/Xttaching Machines, otA which the following is a t'ull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this spcciiicatiomin explainil'lg its nature.

The invention relates especially to devices for attaching a `French or ogee heel. French or ogee heels have generally been attached to the soles of a boot or shoe in two parts or divisions by successive nailing operations, although they have also been secured by aI single gang or group of nails driven from the tread end of the heel, which nails are caused to take an outwardly-inclined path as they are driven b v first forming outwardly -inclined awl-holes. By my invention the heelblank is attaclled by nails driven sim ultaneously, some ot which are driven from the tread end of the heel-blank and some from the riser or iirst section of the blank. The heel-blanks for French heels are usually made in two parts-viz., the seat-section and the tread-section. The seat-section is usually considerably longer than the treadsection, and the object of making the blanks in two parts is to save stock and to facilitate the attaclr ment where they are secured in successive order. These sections are sometimes called decks.

To carry my invention into effect, I employ a templet which has two levels or bearingsurt'aces, one ot' which rests against the outer surface of the lower deck or section and the other of which against the surface of the upper deck or the tread end of the heel; and I also employ awls carried by the same plate or head, but preferably varying in length, the longer being adapted to form the holes in the lower deck and the shorter the holes in both decks, but extending from the upper surface of the upper deck. I also use drivers carried by the same plate or head to be operated simultaneously, but which varyin length, the longer of which are adapted to drive the attaching-nails into the lower deck, and preferably sufticiently below the level thereot` as to leave the heads out of the path of the heel trimmer or cutter. The shorter drivers are adapted to drive the nails through both decks either [lush with the upper surface of the upper deck or t0 extend therefrom for blindnailing the top lift.

In the drawings, Figure l is a view, part in section and part in side elevation, ot' the central and upper parts oi a heel-nailing machine having my improvement. Fig.4 2 is a view, part in front elevation and part in cross vertical section, ot' the central and upper parts of a heel-nailing machine to ['urther illustrate my invention. Fig. 3 is a plan view of the templet and nail-carrier. Fig. i is a plan view of a section of a templet, to which reterence is hereinafter made. Fig. 5 is a view in vertical seetion of a portion of a shoe and heel,

representing in dotted outline the heel-blank t before it is trimmed. Fig. 6 is a view in plan inverted of an ogee heel and a section of the sole of the shoe to still further.illustrate the operation of the invention.

Arepresents thelasterwork-support; u, the slide-jack, upon which it is mounted; o', the bed of the machine upon which the jack is arranged to slide.

l), is a table, which, preferably, is provided wit-h a vertical movement upon a post, b, in opposition to spring-pressure, and which has a slideway in which is secured the templet (l, and which, preferably, is horizontally movable therein.

D is the nail-carrier.

E is the cross-head, which is reciprocated preferably substantially as described in Patent No. 310,894. It carries a revolving head, e, having radiating arms, one of which supports the gang orgroup of awls e', another the gang or group of drivers e2, and the third atop-lift holder and spanker, c3. The templet C comprises the imperforate section c and the section c', which is provided with the holes c2. The templet also has the section or part c3, having' the curved Vface c1l and holes c5, which are in continuation of the holes clot the plate. This section c3 has a pressing or bearing sul face, c, upon a lower or different level than the pressing or bearing surface ci of the main part of the templet, and it is adapted to bear against the upper surface of the lower heeldeck. lVhile it may be made integral with the templet C, it is preferable to make it detachaloo the nails.

ble, in order that sections of greater or less height for use with longer or shorter heels may be substituted, and in Fig. l of the drawings I have represented it as made a separate piece and secured to the templet by the screws e8.

It will be seen that the templet C has the line of holes c2, through which the nails which are driven through both decks of the heel are fed or delivered to it, and the line of holes c5, which delivers nails to the lower deek of the heel only. The awls e may be of the same length; or, if desired, those which operate to prick the lower deck only maybe made somewhat longer than those which prick both decks. The gang c2 of drivers has the short drivers e4, which drive the nails through the holes e2 of the templet into the upper deck of the heel-blank, and the long drivers e5, which drive the nails through the holes c5 into the lower deck of the heel-blank, and which, preterably, are long enough to extend below the bearing-surface e when in their lowest positionl to enter the vlower deck of the heel-blank and drive the nails any desired distance below said surface, so as to leave sufficient stock to be removed in shaping the heel without striking the heads of thenails. Oi' course the trimmedheel-blank will have holes midway its height before it is finished; but these holes are filled with suitable iilling in the finishing of the heel-blank.

In use the boot or shoe is placed upon the last or work-support, the lower section or deck placed upon the heel end of the outsole and so that its rear section extends under the surface cj ot' the templet, the upper deck is placed so that its edge bears against the curved front c4 of the lower section, ci, of the templet, and the table B and templet C are then moved downward, the heel-blank clamped upon the boot or shoe, and while thus held it is pricked by the reciprocation of the awls which form the holes f in the lower deck and also the holes f in the upper and lower deck simultaneously. The attaching-nails are then fed to the holes c2 c5 of the templet by the nail-carrier D,which has a like arrangement of holes for holding Longer nails, however, are fed to the holes c2 than to the holes ci?, as it is necessary that they should extend through the upper and lower decks into the soles of the boot or shoe, while the other nails extend only from the lower deck. The drivers are then brought into position and reciprocated, and the long and short nails are simultaneously driven, the long nails through both decks into the soles of the boot or shoe and the shorter nails into the lower deck and soles of the boot or shoe, the heads of the shorter nails being driven, preferably, below the surface of the deck, as represented in Fig. l, by making the drivers extend below the surface c(i of the templet. This brings the heads of these nails below or within the iinished line of. the heel. (See Fig. 5.)

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a heel-attaching machine, a templet for driving nails at different levels, having the bearing or pressing surface "cf", the bearing or pressi-ng surface e7, and the holes c2 c5, substantially as described.

2. The combination of the templet having the holes c2 and pressinosurface c7 with the removable section c3, having the holes e5, substantially as described.

The combination of the templet C, having the holes e2 c5, the section c3, having the bearing-surface c, and the front curved edge, c4, and holes c5, substantially as described.

il. The combination of the last or work-support, the templet having the bearing-surfaces c c7, the holes ci c2, with'the gang otv awls to enter the holes c2 and a gang of drivers to enter said holes, and comprising the group of short drivers eL1 and the group of vlong drivers e5, substantially as described.

5. The combination of the last or work-support, the templet having the two bearing-surfaces cG c7 at diil'erent levels, and holes c2, extending to the one level, the holes c5, extending to the other level, and a gang of drivers in two groups, the shorter of which are adapted to drive nails through the shorter holes and the longer of which are adapted to drive nails through the longer holes and to exten d below the ends of said holes to drive nails below the level of the deck of the heel, substantially as described.

(5. The combination, in a heel-nailing machine, of a templet having holes c5 with a gang of drivers of a length greater than the length of the holes, and suitable operating mechanism for reciprocating the drivers to bring their driving ends below the ends of said holes, as and for the purposes described.
