' NAILinG PLATE n non Lgisrs This` invention relates' to a nailing plate ot' hard metal, attachable. tothe bottom of4 a Wooden last, and adapted to clinch .they points of nails or tacks driven intouparts .ot The plate is provided a shoe on the last.

with an orifice adapted to receive a nail driven through an inner Y`sole and into the Wooden body of the last, to temporarily secure the inner sole'prior to the Ilasting opera.-

tion. The 'orifice is. neeessanilyV fof much larger diameter than the nail,v to prevent dif.-Y

vFigure-6 is a section Online 6 6 of'Figj I pressed pulp,

L orifice 13, so that said margin is adapted to Vconstitutean element of a lockjoint. This ,s preferably accomplished by indenting one side of the plate or clinching portion 12, as

best shown by Figures 2, and 7, to form seg- Y mental seat portions 22, segmental edge portions 28, at the outeredges of the seat portions, and radial edgel portions 24,' at opposite ends of the seat portions. These portions may be formed by a suitable die,

adapted to displace` portions of the metal toward the under side ofthe plate, some of `the displaced metal being indicated by dotted lines in Figure 7, this being subsequently ground'oif to flattenthe under side of the plate. .The diameter of .theV disk forming he nail-engaging Vportion 20, is such that when the disk is 'placed on the upper side ofthe clinching portion 12, and subgected 'to pressure, the marginal portion of the n disk is conformed to the diversified margin may bev engaged with the `di-versified mar gin byv another singleoperation, so thatthe of the orifice and Vfirmly interlocked therewith, so that the nail-eiigaging portion 2O is y practically inseparable from'the'clinching portion .12.1 The. orifice margin may be i diversified as above described, by a single .nperatiom and the 'nailengaging1 portion cost of production is reduced to al minimum.

I have found :that the nail-engaging portion 20, made of iiidurated fibel', is suiiicientlyV strong` and durable, and may be penetrated many times by a nail 15, without becoming inoperative, the durability of said l portion being practically as great as that of i ing portion 2O is conformed, to form a lock f a wooden last.

The margin of the orifice'in the clinching portion 12, may be otherwise diversified, as

shown, for example, by Figure 10, which shows a marginvprovided with beveled'faces 26, to which the margin of thefnail-engagjoint.

It is obvious that the invention is not limited to a heel plate, and may be embodied in ka plate formed for application to theltoc portion of a last bottom, or to a full length nailing plate formed to cover the entire bots tom of the last, and providedwith a plurality of nail-engagingfportions 20.l

As shown by Figure 11, vthe nail engaging portion,-here designated by 20a may be posii' tively connected lwith-the plate by forcing said portion `under pressure into'an orifice 13, the wall of which is ynot diversified, the

j Vportion 20BL being somewhat thicker than the plate-*12, and forming a slight protuberance on the inner side of the plate, the last be- Ving provided with a shallow cavity 27 in its bottom to receive Vsaid protuberance. It is Anot essential, therefore, that the upper side of the nail-engaging portion be lexactly flush with the upper side of thev plate.

It will be seen that in each of the illus-v trated embodiments of the invention, the portions 12 and 20, or 20'sy are positively` united, arior to the attachment of the device to a last, so that said portions collectivelyy constitute an article of manufacture, adapted to stored and handled as a unit,vand attached as a unit to a last. Ineach of the forms shown by Figures 1 to 10, inclusive, said unit is attachablewithout any ada-ptation of the last other than the formation therein of the usual recess to receive the en.- tire plate 12, and locate the bottom of the plate flush with the bottom of the last. In the form shown by Figure 11, the only modi# iication of the last is 'the formation of the shallow cavity 27.

I claim: y

1 As an article of manufacture, a nail-V ing-plate having a puncture-resisting clinching portion and a puncturable nail-engaging portion surrounded byy and interlocked with the clinching portion, said portions being positively connected, so that the plate is attachable as a unit to a last.l

2. AS an article of manufacture, a nail-l ing-plate having a metallic puncture-'resisth ing clinching portion, and a non-metallic compressible and puncturable nail-engaging portion, surrounded by andk interlocked with the clinching portion, said portions be ing positively connected, so that the plate is attachable as a unitY to a last.

3. As an` article of manufacture, a nailingplate comprising a metallic puncture resisting 4body portion having a nail-re cei'ving orifice within its margin, of much greater diameter than the nail intended'to be received, anda puncturable nz'iil-engagingl portion filling said orifice and intei'loclred'` with the margin thereof, said portions .being positively connected,so that, the plateV is attachable as a unit to a last.

4. As an varticle of manufacture, a nail` ing-plate comprising a metallicfpunctureresisting body portion having 'a nail-ree ceiving orifice withinits margin, of much greater diameter than the nail intended t-o be received, the margin of saidoriiice being formed to constitu'tean element of a lockv joint, and anail-engaging portion" of compressible and puncturable material filling l said orifice and marginally conformed tothe margin o f the orifice, to form a lock-joint, said portions being positively connected, so

Aphat the plate is attachable as aV unit to v ast. v

'5. As an article of manufacture, a nailing-plate comprising a metallic puncture-A resisting body portion having a nail-receiving orifice within its margin, of much greater diameter than the nail Vintended to be received, the margin of said orifice being formed to constitute an element of a lock joint, and ay nail-engaging portion of indurated liber filling Vsaid oriiiceand mar-- ginallyy conformed to the margin oi the orice to i'orm a lock joint, said portions heing positively connected, so that the plate is attachahle asa unit'to a last. *l n 6. As an article of manufacture, a nailingplate comprising a metallic punctureresisting body'portion having a nail-receiving orice Within its margin, of much greater diameter than the nail intended to be lreceived, the margin of said oriiice being diversified to constitute anelement of a lock i joint, and including segmental seat portions, segmental edge portions atthe outer edges of] the seat portions, and'radial edge portions at opposite ends of the seatportions, and a nailengaging portion of colnpressible and puncturable material -filling said orificev and c marginally conformed to the said diversified margin, to form alock Joint, said portionsv vloeing positively connected, so that the plate is attachahle Vvas a unit to a last.`
