Application iled March 25, 1920.

To all whom t may concern.'

Be it known that l, EMIL iii-iras, a citizen of the Swiss Confederation,,residing at 1vllangen, Canton Zurich, witzcrlzlind, have invented certain new and useful improve ments in and Applicable to Machines ior Attaching` Heels to Boots and Shoes, of which the following is a specication.

The present invention relates to improve` ments in and applicable to machines used for attaching heels to boots and shoes from the inside or" the same. and has for its object the construction ot a heel nailing appliance by which all the nails for a heel may be driven in simultaneously at the same or dilerent inclinations to the heel and to each other, whereby the heel and its pieces are held together and to the boot or shoe by inclined nails which may be inc"ned by relation to the outer shape ci the heel.

The object or the invention is to provide an appliance ci the lrind described which may be easily inserted in the boot or shoe, without distorting its shape and a 'further object of the invention consists in forming; applianceV or nail bloclr its constituent parts in such a manner that the nails may be driven in the heels at the very periphery thereof thus securing' a goed and rin connection of the parts.

The invention farther consists of details of construction, which together with the iteatures first mentioned, will be better understood by reference to the drawings, in which Fig. l is a Sectional elevation oi the nail bloclr together with part ot a boot with heel to be attached.

Fig. 2 is a section talren on line A-B or Fig. 1 the boot being shown in dotted lines.

Figs. 3 and i are cross-sections on lines (l-D and E-F of Figs. 2 and l respectively viewed in the direction of the arrows.

Fig. 5 is a top view of the nail block.

llhe nail block according to the construc- `tion shown in the drawings by way of an example comprises a rod l carrying a head 2. The latter is composed of three superposed pieces iirmly iiXed together. rlhe head 2 has seven holes 3 each adapted to receive a nail 6 and a iiexible nail driver 7. All the drivers 7 are fastened on a slide 8 which is slidably mounted on the rod l. To

serial no. scarsa guide the slide 8 a in l0 is provided on the head 2 projectinginto a bore 1l of the slide 8. r.the slide 8 is moved up and down by any suitable device not shown in the drawing and a sleeve l2 is fastened to the head 2 overbridging the gap between the head 2 and the slide S. Each driver 7 consists oi a closely wound steel wire and loosely fits tl e bore 3 in such manner that it may move in said bore without undue friction. Each bore 3 consists of three parts set at angles to each other, each part is straight and the length of the uppermost part 3 is equal to or greater than the length of a nail 6 to be driven in theheel it or' the boot 5. rlhe angles at which the bores 3ZL are drilled are varied according to the inclination desired to be given to the nail to be driven such inclination being` determined by the shape of the heel. lt will be seen from drawings that owingv to the particular shape of the head 2 and of the bores 3 in it and by the employment of the flexible drivers '7 the head 2 may be placed well within the hind end of the boot and nails be driven in the heel `from very near the hind Vend of the heel tlnis giving the istier i., goed hold and formingv a close joint.

When the nail bloclr is being used the slide S is lowered and therewith the drivers 7 so that the nails 6 can be placed in the bores la oi the head 2. rlhe boot 5 and the heel l to be attached are placed in position on the nail block and the whole is moved under the cross-head of the machine. The slide 8 is moved upwards in the direction oi.5 the arrow l whereby the nails are forced ont ol the head 2 into the heel d by the drivers 7.

The number, position and inclination ci the holes may be varied according to the requirements of the heel and ot they shape thereof.

l/"Vhile l have described what l believe to be the best mode of carrying my invention into commercial use, l do not confine myself to the details, as they may be modified without departing from the spirit of the invention.

Having now described my invention, what l claim as new, and desire to secure by Letters latent, is-

A machine by which all nails for attaching a heel. to a boot may be simultaneously driven into the heel aty angles to each other 011 which the said drivers are mounted subzmd o the heel Comprising' in combination stentially as` described. l V Vd head having a plurality of bores, the Yparts In testimony whereof I afix my signature of each bore being` at an angle to each other, in presence of two Witnesses.

the uppermost porliion of each bore being; Y EMIL PEYER. adaptedto receive a mul, a closely vcoiled Witnesses: Y l steel Wire driver 1n each of said bores, and FRITZ TSLE,

a slide movable on a rod carrying said head MARIE ROTHIMANN.
