Be it known that we, WILLIAM F. BANGROFT and. HARLEY A. STONE,-citizens of the Unitedv States, and residents -,of Worcester, in the county of Worcester and. State of Massachu- 7 setts, have invented certain new'anduseful in] provements in Machines for :Making Wire Fails, of which the following isa specificatron, accompanied by drawings forming a part of the same, and illustratinga wire-nail machlne embodying the several features ofour invention, in which Figure 1 shows a top view of the machine. Fig. 2 is a transverse'sectional view online X X, Fig. 1, looking in the direction of the arrow 1 and showing the mechanism forv gripping the wire. Fig. firepresents, a detached, portion of the grippingmechanism. Fig. 4 is a cent-ral'longitudinal sectional view with the 2 operating parts in the position in which a nail is headed; Fig. 5- is a transverse sectional view on line XX, Fig. 1, looking in the direction of the arrow 2 and showing only the mechanism for cuttingjoff the wire. Fig. a topview of a portion of the nail-heading mechanism. Fig. 7 isa perspective view of a portion of the nail-heading mechanism. Figs. 8 and 9 are sectional views of aportion of the wire-cutting mechanism on lines S and Y,

5, respectively, looking in the direction of the arrow 3. Fig. 10 is a central longitudinal view of the machine with the operating parts in, the position opposite that shown in Fig. 4:. Fig. llisa. side view, of a part of the heading mechanism, partly in section; and Fig. 12 isa front view of a part of the heading mechanism. I Like letters refer to likeparts in the several views.

A denotes a table mounted upon a suit-able frame-work, and upon which the operating parts of the machine are supported. B is the main drivingshaft, to'which power is imparted through the belt-pulley B. Upon the shaft B are the bevel-gears B B, communicating mo' tion through similar bevel-gears, B B to the V shafts'G and-D=---A.slo, ted crank-platefi, on the shaft 0 carries a cran piiiXERrmnnected b J a link with an arm, E, swiveled. in the rdckh shaft E, to which an arm, E is attached. The arm E is connected by alink, E, to a'stud, E", projecting. from a wire carrier. E; such as is now in use uponfmachines of this class. The wire-carrierhas a reciprocating motion along the way E,and at each forward movement carries the wire required to form the nail into the machine.

' We have not herein shown in detail the construction of themechanisnremployedginfeeding the wire to the nail-making portion of the incorporate the same in a separate application. For that reason the feeding mechanism ishereby disc1aimed.- I F is a raised block or anvil either. securely attached to or cast as a part of thetable A. Upon the "perpendicular 'side-- or -"facc ef anvil F isa way,'in. whichslidesa'block. F, resting on the adj ustingserew F bywhich the block F is raised to bring the gripping-diesin 7o alignment with the wire and the heading mechanism. The block F has a fixed grippingdie, F. and alever, Fj, pivoted in the block FatF.

The lever F carries a gripping-die, F and 75 is rocked on its hearing by the action of a cam, D, on the shaft D, on which the free end of the lever F is held partly by its own weight and partly by means of a rod, F, and spiral spring F As the gripping-dies are opened by the depression of the free end of the lever F, the wire is fed into the machine byt'he forward reciprocating motion of the earrier'E. The diesF? and F are then closed' by, the acthe lever F, thereby firmlyholdingjthe wire in the dies F F, while the ope'rationof head-- 'ing is performed andthe'nail is cut off. The dies F and F are adjusted laterally in ways theirposition' by 'means of the gibs F and screws F. We insert a steel tube, F, be-. tween the ends of the dies F F, with its flanged end resting againstthe anvil F, for thepurpose of transferring the force of the blow 95 employed 'in heading the nailfrom the gripping-dies to the anvil itself.

1 The wire having been seized by thegripmechanism, as it has been deemed advisable to tionof the cam D in raising the fr'eelendof 8 by the screws F, and ar se u elyt mp i 9 ping-dies F F with the end projecting far ble A. The block G carries a sliding'plate,

G sliding horizontally in'ways formed inthe block G, and havinga header, G", (seen in a detached and perspective view in Fig. 7 and consisti-ng' ofa steel bar held inagroove in the lower surface of the sliding plate.G"

- by means of the binding=bolt G.

A screwt-hreaded rod, G, projects from the block G, having an adjusting-nut, G", 'against. which the plate G, attached to the sliding plate G is normally held by means of the spiral springs Gflpl'atred between the block G and the plate G1,, 6.

The header v(5: having been brought into alignment with the wire hel-din the grippingdies F? F, as shown in Fig. 4, the ram H, sliding in ways on the table. A,'is brought against the end of the sliding plate G by the eccentric B on the shaft B, forcing the header Gagainst the end of the wire held in the dies F F and forming the head of the nail; The motion of the parts is then reversed, assuming the position shown in Fig. 10, thedies h F are opened, releasing the wire, which is again fed the length of the required nail, the gripvfpiug-dies F Fareclosed by the action of the cam D, and the cutting and pointing dies I are brought against the-wire by the action of the eccentrics C on the shaft-JO and l on the, shaft D. 'Thecutting and pointing dies are,

carried in blocks 1', slidingin ways on the-table A, and are held in position by the gibs 1, intermediate blocks, 1, and'bin'dingscrews I, which pass through slots 1 and enter the slid ing blocks I. The adjustment of the dies I is made laterally by the screws I,jour' the blocks 1 and passing through the screwthreaded lugs P-onthe intermediate blocks, 1?, whileth'e adjustment of the'cutting-dies in the direction of their length is efl'ected by the ad'- justable counectionsbetween the sliding'blocks 1 and their actuating-eccentrics 0 D The connection between the sliding blockG and arm G is adjustable, as is also that between the sliding ram H and its eccentric B".- The relative. position 4 of the. nail to the header'is shown in Fig. 11, in'which a denotes v the wheels held by the gripping-dies represented" by b, and the nail, as it is carried forward by the feed motion,will occupy the position 0, unless it should have been entirely sev ered by the action of the cutting-dies. Itwill sometimes occur'thatthe nail will not be sevcred from the wire, iuwhich case the downward motion of the header G will clear-the nail from connection with the wire, causing it to fall throughthe opening (I in the table A, and

pairs or adjustment. 7

by the proper adjustment of the sliding plate G by means of the adjusting-screw and tint- G"' the header G 'is made tojustclearthe v of the wire held by the gripping-dies.

The cam D on the shaft D, by which the gripping dies are actuated,is so shaped as-to allow the free end of the lever F to falland open the gripping-dies, thereby releasing the wire during the time that the wire is being fed to:

the machine, or during the rotation beneath the lever F of thesnrface from e to f. The

dies are then closed with a moderate pressure" on the wire from f to g, or while the operationof cutting and pointing is being performedjby the action of the dies I, while from g to f the lever F is raised, so as to bring a firm pressure on thewirein the grippingdie's while the operation of heading the nailiis performed.- Modcrate pressuge 'onlyis applied while the nail is vbeing pointed and out ch, as itv is necessary to allow the wire to move back in the grippingdies as'the nail is out ch, in case any pressureis i shafts B O D are/in the same horizontal plane i and also in the sam'ehorizontal plane as the gripping and cutting dies and the header Gf when in the position of' heading a nail. The act-ion ot'al l the eccentrics is brought, therefore,


in a direct line with the centers of. the shafts. BC D. The action of'the header a'sa (sleet-er" in clearing the completed. nail from thewire is peculiar, in that itis parallel with the nail as it is brought in contact with it,and its-position is easily adj us'tablewith referenceto the point of the nail, We are aware, howevicnthat a header has been employed to clear the nail. Such we do not claim, hio'adly. The sliding block F is easily removed from its ways in the anvil F, and the opposing ends of the grippingdies F F overlap the end of the steel tube F so'th'e force of the blow in heading the nail is received by the anvil throughthe tube F and ment of all the operating parts of the machine upon the top of the table A allows all the parts of the machine to be readily reached for re the ends of the dies F- and F. The arrange Wedo not confineourselves to the palticular method of constructingtheadjustablepbnnections between the several eccentrics and the parts moved by them, nor between the Slidingblock'G' and the arm G, all of whiclgt, as shown in the drawings, consist of the w ellknown form of a right and left screw-threaded bolt t I I .7 i
