and their operation, being hereinafter referred to.

The device'for cutting'the nail-bar into proper lengths will be duly explained.

isisimilar in its general form to the well-known Singer sewiiig-ninohine, although of much greater proportions; that is to say, it is composed of a. base or bed-plate, B,

.When at. its extreme inwardor rearward 1 position, the end of "the tappetshould be somewhat in rear of the mould-hlock, .or so as. toleeve abundant space for d reception between the two of the shoe-blank,

The necessary reciprocnting rectilinear" movements of the tappct f'zoward and away from the mouldblock are effected as follows:

A horizontal furcated 'tripping-lever orpsllct, y,

rests partially upon, and is firlcrunied, as shown at Z,

As-the actuating-point d of thewiper 0*, (shown in Figure 12 of the drawings, which is a face representetion of such wiper,) posses by the roller'b, 'aiter advancingth'e expelling-trapper, w, strikes the curvedrenr arm c ot the pallet 9 and causes such pellet to de scribe a partial revolution upon its -fulcrum,- which effects a. rearward movement of its arm a, and, sis-ziconsrquence', a. retraction of the tappet 10', which thus remains at itsextreine rearward position until the 'wiperlias completed a revolution upon its. axis, and again strikes .the roller 1:,snd'efi'ects an advance of the iappet.

- The .ahov'e description embraces the construction and-organization of myimproved machine, and will enable skilled or intelligent mechanics, to whom this specification is'chieiiy addressed, to build'it. The operation of the above-described mschine is as follows, inbeing premised with the remark that the iron strip, of which the shoes are formed, is to be suit-ably f'easedfor forming the groove about the nail-holes; and maintained. at a red heat'while it is fed to the machine, the position of the difi'erentparts of the'mzn saline being as shown in Figure-lief the accompanying V driiwiusgs, that is, with the feeding-carriage retracted to its l rthcst cxtcnt, the formers or wings H H wide open, the perch-carrier elevated, and the mould-block and cnlking-bzualso elevated {it being-remarked that the null-piste has been insert-ed in place between theclump-bar ji, and the ieeding-cnrringe g and pushed inward until it strikes against the stop or gauge 12:, before mentioned, and that the punch-carrier has first made one descent; and cut a pieceffrom ofisuch strip, length sutiicicnt to forms shoe, such piece lying upon the top of the standard of the machine-frame, below the anvil U, and in rear of the mould-block r, or between it and the eX-pelleror tnppct the wings H H closed, the portlnn f of the wiper a,

(see fig. 11 of the drawings) simultaneously with the start of the wings, lay striking against the rhlle-r If, and advancing the her, serve: partially to straighten thetoggles W517, and to depress the 'ilu'ward firms) h ofthe levers V V", and lower the punch-hat cr w-- rier R, and the clamp-piste or anvil U, until the latter, or its stud c", presses upon theshoe, and clamps it to the mould-block r, and holds it firmly in position during thepiosing of the wings, which is effected by the-entire straightening oi the toggles WWVJ As soon as the toggles W, W we become straightcued, and the wings H H closed upon and bent the shoe, the concentric portion g of the wi'pcr OTBYOIYOI past th'c rollcr m, without actuating it, while the 000- tinned revolution of the th iving-shaft, by means of the irregular or cent-groove in the disk so notuates the lever c? as to elevate the culkingnnir a, and bend the heels of the shoe upward against the outer edge of v the anvil rind n 3011 o )osit-e sides of its studor a V 1 .fi u 'JGOillOll, borersnzcntmneajl, thus Iorrmng the calks upon the shoe hes ls. l t

By the time the culiritg-bar a has reached its highest posit-ion, the longest point e of the wipcrc' strikes the mile! at, and completes thci'crward movement of the yoke X, and the straightening of the toggles \V Ti v This straightening of the toggles W: Wf co the deuce it oi the puuch cnrrler it, and the sliding ba'r Y, carrying urn-prongs 1; 1 the punches having the effect of wnolly or partially punching the nail-holes in the shoe, and the prongs having the effect oftapefln'g. the cults fiunwi by the calking bar a, it being borne in mind that the lower end of the punch-carrier, or that enclosed within the radius efi rows of punches, well as the upper surfnceof the-m0'uldblock,zar6 ofsuch conilgumtlon as give the necessary shape or curve to the fire-cs of the shoe. g Thedesceutnf the punch-carrier, as it pnsses by the orifice uglhfin c mentioned, has the cflect-of severin the slim-strip at this point, preparatory to rem revolution of as driving-shalt of the machine.

It should also he borne in mind at this point, that as the anvil or clamp U is resting'upon the mould;

block during. the lest part of the descent of the punchcerrier, s yielding connection between such clamp and carrier becomes necessary, 4

The shank and spring, before mentioned,"providc' for-this necc-ssity. f 'L It will also be well to call the readers attentiob, I this point, to-the'fnct that the lower part ofthe punchcarrier, and preferably that of the punches tbeumelva, should be hollow, and should contain water for MI ing the temperature of these parts, as well as that!!! the completed shoe, which otherwise would injure or incapacitate them, and cause a cessstion ofiworkin'gof L the machine, I p r As soon as tho point-e ofthe wiper o passefi b the roller 'm', the toggles-are suddenly cont-meted y I suitable cz'nn, spring, or other device, and the-punch- .carrier and sliding bar Y are suddenly elevated.

After passing' the roller m,the point a of the wipe:

o comes in contact with theshorter'nrul of th'eftrlppor yg'und partially turns such trlpper on .ltsflllcrnm, by

advances the tzippet w".

The machine, constructed asahove described, is very compact in bulk, and may be built at moderate gosh this means advancing. its iongeiarm, on'dsifzth it the I r feeding-carriage, which, in turn, carries with. it; the i its elements or mecinmicai movements are all positive shoe-strip, and inserts such strip anew to fire action i of. the machine.

Soon after. passing the tripper, the wiper o strikes the roiler t of the long lever s, and pushing thei'ree end of such lever ontwgrrd, causes the carriage g to slide over the'shoc-strip', anti take a, fresh grip thereupon.

I have now shown how the nail-strip is fed into the machine, and out to the desired length, and how it is' bent into shape, and nionlderl and punched; v

I will now explain the action of that portion of the machine for expelling the perfected shoe, and to do this, I go'back to the point and time at which the; 'wiper o is impinging against, and mt-noting the tripper 0 and adwincing the shoe-strip;

At this point, the largest portion or point of the wiper or cam c, which is somewhat in rear of that of the wipelzo, comes in contact with the roller b, and advances the'tappet m", and expo-ls the shoefrom the machine, the anvil, punch-carrier, and. eaiking-har, at this time, being at their highest positions.

After passing by the roller 2 the wiper c" strikes the curved rear arm a of the pallet, and retracts its arm a, and with it the 'ta-ppet, substantially as hei'ore explained.

It will he ohrions ihat while the wiper 0 is impinging against the trippcr rrrnd the roller t', the toggles W W'nnd J J are being cont-racial or short-j cried, and, as a conscqnencg the PIJUClJ-Cfll'fliil ii l'lfl milk-tapering bar elevator], and the wings H lf'o'jiened,

while at the some time, by the revolutionoi' t-her iisk y, and the act-ion oftl block and ralkingharc. are-depressed.
