The features of novelty in my improved ma- Y chine for making metallic nuts isthe peculiar f arrangement and operation of itsy parts,l by which Athe nuts formed in the said machine are j thicker than the bar from which they are cut,
this being accomplished by forcingall or nearlyall the metal displaced in forming the hole in the nut into the body of said nut. lhe
advantages `that follow from this improvement are self-evident. t
`The nuts made .in mymachine will be more perfect in form, rand the wads which are rel moved by other machines informing the holes in the nuts, and which have to be sold at a I -very lowprice as scrap-iron,.being by my pro cess .put inthe. manufactured article, causes justed in its position yby means ofthescrew- Y the improved nuts made by my machine to cost considerableless than the lessperfect `nuts made by yanyother known machine.- The nut-boxinwhich the nuts are forlncd in my. said machine may he constructed in any 1 manner that maybe deemed expedient.

cams a vand b on the Y A suitable form of themetallic frame of my improved nut-makin g machine is represented in the accompanying drawings, andY designated by the letters N, lt 1t, Q Q. The respective pairs of sliding plates G .B and F H are secured in shouldered recesses in the vertical positions of the frame, 'as shown at R B, by means ot' the series of inner beveled bearers, e" c', Fig. 4, and the series' of outer bcveled bearers, 11" F and'G G', and a suitable which setscrews pass through the said bearthe projections from the said portions of the frame above and below the sliding plates B G and F H, and act against the outer edges of the bearers F F, G G,b b ;I or the said sliding plates may be supported in proper potions in any other suitable manne The shafts J K work in suitable bearin gs, and
rel and also ot' the camo beingy shown in Fig. 6.
are' rotated by means of cog-wheels E E on on the driving-shaft vI. v
The accompanyingdrawings represent the respective parts of my improved nut-making their inner ends, which gear into a pinion, D,
machine in theposit-ion they are thrown into immediately after the last movement in forml;v inga nut and discharging itfroin the machine.
From this position the said parts move as fol g lows: When the machine is put in'motion;7 the cam p strikes against the surface p at the iii-- ner side ofA the aperture in. the sliding plate G,and carriesv forward the punch d toward the mouth of the .nntlbox, and at the same tnncthe cam c st rikes against the rea-r edge of the aperturein th'e'sliding plate H, and produces a rearward motion of the bottom j of the nut-box preparatory to thc reception within said box of the redhot blank cut off bythe punch d in its forward movement.
" lhe' said slding'platc. H is thrown outward until its outer end is brought in contact with the adjustable projection Z" from the spring A', andl at the same time this takes place the 'advancing punch d brings the blankv nut just-in contact' with thc bottom of the nntbox. While vthe segment-shaped portion of the vcam p is acting upon the punch d through the sliding plate G, the cam b strikes against thel surface c at the inner side ofthe aperture in the plate F, vand carries forward the round punch e, and at the same 'moment the projection o of the cam o strikes againstthe surface l', Fig. 6, at the inner side of the aperture-of the plate B, and carries forward the round punch j". The said cams b and o are so proportioned that they carry forward the round 1' punches eandfinto the hot yieldingnut-blank until they nearly meet-in the center ofthe same,
,1 which movement ofthe said punches forms the hole in thc nntblanl; by forcing the metal from the center thereof into the body of the same, thereby causing the nut formed to be thicker than the bar from which it was eut, and thereby giving the top and bottom sides of the nut the proper form by expanding it against the vbottom of the nut-box and the end of the punch d, the proper forms being made in the end of the said punch and the bottom j ofthe nut-boX-the bottom of the nutbox giving back to allow the-nut to increase in thickness, and at the same time to press hard enough upon it to give it the required form as the nut expands against the said bottomby the increased pressure from the center outward, which thus insures absolute perfection of form at every side and angle. The projection o" of the. cam o passes over the surface l of the plate B and ceases to operate upon the round punchf, while the round punch c is still advancing and, while the segment-shaped por'- lthe round punch e is carried forward by the cam b until it passes through the nut and enters a short distance into the aperture in the end of the angular punch d left by the receding round punch f', where it deposits the wad which was formed i-n the center of the nutblank when the ends of the round punches were brought nearly in con tact with each other, as before described. The moment the cam b ceases to carry forward the round punch e the cam a strikes the surface m at the outer side of the aperture in the plate F and withdraws the said pn uch, and simultaneously with said movement the cam c strikes against the inner side of the plate H and carries forward the bottom of the nut-box to discharge the finished uut. The moment that the finished nut is carried ont clear of the nut-box it is separatedfrom the bttom of the nut-box by the action of the spring-bar m, which is forced inward against the nut bythe projection r on thecog-wheel E. Y
Immediately after ja nished nut has been discharged from' the machine the angle o' otl the cam o strikes against the surface l', Fig.
6, of. the plate B, and thrusts the end of the round punch f' a short distance out of the end of the angular punchd forv the purpose of discharging therefrom the thin wad (which was deposited therein in forming the previous nut) preparatory to the forward movement of the said'punch d for the purpose of forming another nut by the aid of the movements of the other parts'of the machine, in the manner substantially as hereinbefore described.
` What I claim as my invention, and desire to secure by Letters Patent in the manufacture ot' metallic nuts; is-
Forcing a portion or the whole of the metal displaced in formingy the holes in the nuts in th'ebodies of the nuts, by which I am enabled to make the nuts thicker and more compact than the bar from which they are cut, all substantially as hereinbefore set forth.
