'. lO ALL'WH'OM IT MAY CONCERN:

Be it known that I, FRANZ HAIN, of the county of Gasconade, in the State of Missouri, have invented a new and useful VImprovenient in FeedingfDevicesfor Nail-Machines, and such other machinesin which a similar feed-motion is required or useful; and I do hereby declare the following to be a full and true description thereof, reference being had to the accompanying drawings, and to the letters of reference thereon.

It is well known that when the nail-plate is fed to' a nail-machine 'by `the hand of an operative, the plate is held in a' platelcarrier or holder, which, after each cut by the shears of the nail-machine, is pressed forward' to offer new metal to said shears; and which, after each feed-motion, is turned lhalf roundin the direction directly opposite to the turning in the preceding motion; and which, lastly, is slightlyraised at the forward or nail-plate i end, to allow the turning motion just described without bending the nail-plate. Now, the general nature of my linvention is in a correct imitation of the hand-feedrnotion,'by the application of mechanieal devices to produce the same, and as the said hand-feed motion is a compound of three motions, to wit, a forward longitudinal, a reciprocating turning motion in' anfangle of one hundred and eighty (180) degrees, and a slight vertical motion,

Vthe detail nature of my invention may therefore be stated asV in, firstly, the application of a falling weight to produce the horizontal forward motion of the plate-holder, carrying the nail-plate; secondly, the arrangement of a ratchet-wheel and escapement-movement, to cause the turning of vthe p1ate-holder in opposite directionsin every two consecutive feed-motions; thirdly, pivoting the plate-holder in such wise that b'y the application of' proper devices the forward end thereof may be raised suiiiciently to allow the nail-plate to be turned without twisting it; and fourthly, the construction of the devices used in producing the motion `just described, and the arrangement thereof in such wise that they all act properly upon the plate-holder in one interval of time, being the interval between the end ofone cut by the shears and the beginning of the next cut'. v

To enable those skilled in the arts to make and use my improved feeding-machine, I will now describe its detail construction and operation, referring to the drawings,.of which-- Figure 1 is a generalpl'an.

.Figure 2, a side'` elevation.

Figure 3, a frontend elevation. t Figure 4 is a sectional elevation from the line m y of plan in fg; l. Figure 5 is a section at linearly1 of plana' l l .As my'said invention may apply to sundry and various forms of nailmachines, and other similarly-acting machines, will not describe the construction thereof, and inl the following refer only to such parts thereof as are necessary to fully understand the invention here claimed.

Myl said feeder is arrangedin front of the cuttingeshears of a nail-machine, so that the plate-holder occu- `piesfthe position as usual in the hand-feed. To sustain the parts, I arrange aframe, A, which, however, may

bepart ofl the nail-machine. p Assliown in` the drawings, B are the cutting-shears of the nail-machine, operated inthe usual manner, and arranged as usual. The saidsbears B have the cutter b, and act upon the nail-plate C, when the same l-ies fiat upon the base-block b1. The base-block 61 is adjusted with reference to the shears B by the several screws 62 and b3. To properly guide the nail-plate, it may be convenient to arrange a standard, '0, adjustedlaterally bythelslot in the horizontal Ashank and the set-screw cl. From the same power-source which operates the nail-machine and its cutter-shears B, I drive thevdevices producing the feed-motion of the ,nail` plate holder, D. Said holder D is made of metal, usually wrought or cast iron, Vin the form of the usual plateholder, having the jaws ci', which by the usual screw dl (or a dampingrihg) hold the nail-plate C. The holder D is held in the support-block, E `which is pivoted by its pins, e, in the adjusting-pins F of the frame. The

said piece F is pivoted on a part of the main fra-me A atf, and its position is maintained at the other end by the guide-bar fland set-screwf2. fl is attached to the ,main frame by a pivotbolt atfa. By moving the end of F along its guide-bar f1, and then securing F in position byfz, the direction of the plate-holder is changed in such wise that the nail-plate is cut to a proper slant by the cutting-shears B. Then, rby the reciprocating rotary motionimparted to D, (yet to be detailed,) the shears B cut rst'one side and then the other of each bit of nail-plate vto the proper slant, forming the wedge-shaped chip needed in the nail-machine for la proper forming of the nail. At the rear end of the holder D, I connect-the same vwith the cross-head D1, however, in

such wise that D may freely turn in the joint with D1. f D is guided at yits ends on the guide-rods D2, which are secured in the supporti-block E. To D41 I attach the ropes'or chains D3, which pass over pulleys D, (also secured on E,) and to which is hung the weight'Du It will now be 'seen that the several 4parts D, DI, D2, D3, and D, being sustained o'n or in E, may be freely subjected to the motion imparted toE, (and yet to, be explained) withoutl interfering to' disturb the same. As the holder D is permitted to pass through E in such wise as' to allow a longitudinal motion of D, whenever, then, the spring-devices yet to be described permit, the action of the weight D5 pushes D, and with it the nail-plate C, forward, until the nail-plate reaches the usual feed-stop C', and thus the first elementary motion described in the nature of invention. is performed. -li'rom the rotary motion of thepower-source I have arranged the reciprocating motion of the bellcrank levers fc, (pivoted in the frame A at x1.) To one of said levers, L, I connect the pawl y. This operates the wheel y1. (It may be useful to guideA the pawlg/ by the spring y2, connecting therewith, and with the frame A.) The wheel-teeth of y1` operate upon the regulating-lever Y, (which is pivoted to the frame A' at 1 /3,) raising the en d thereof, which overlies the nail-plate C, the spring Z acting whenever Y is released by the operating-tooth of y", to draw the lever Y down on the nail-plate. Thus the lever Y, in rising, permits the feed-motion of the nail-plate, and after said feed-motion has been made acts with the stop O and the guide-standard C to properly place thenailfplate on the base-block b1, and permit the cutting-action by the shears B. The toothed wheel y1 is supported on the shaft z, restingin proper bearings on the frame A. At the other en'd of the shaft z I place the ldisk G. To this is imparted an intermittent rotary motion by the action of the pawl y, wheel y1, and shaft z. On the disk Gr are the pins g. These operate the arms g1 ou-the vertical sha'tgg. The faces of the pins g are cut so as .to pass the inclined edge of one lever-arm, g1, when either one pin isvoperating the lother lever'gl; then, owing to the position of the two arms g1, byv the action of one pin one of said levers is carried forward, (the other lever being inactive,)` and in the next movement the pin preceding theonejust acting will carry the other lever back, (the iii-st lever being inactivef) thus imparting to theshaft g2 a reciprocating rotary or a simple pendulous motion. On the shaft g2, which vis'siipported by a proper standard on the frame A, I arrange the lever-g3, which by its pin produces a reciprocating transversevmotion in the link 7L, this being guided by the pendulum-lever z, pivoted at h2 on the frame A. The link h' acts on the adjustable slide k3, which is connecting by the tap-bolt z, and with therack H causes a reciprocating motion thereof. In order that this reciprocating motion of I-I may Acause a proper reciprocating vrotary motion-of the plate-holder.D,the link ha has a slet, in which, by changing its relative point of attachment to Hby the bolt h4, proper allowance is had for the relative motion of the parts.r

The rack H is properly guided on the adjusting-piece F in its reciprocating motion aforesaid. TherackHacts to turn the pinion I which is on the cylindrical bosse', fig. 5, surrounding the plate-holder-D, and restingin the support-block E. New, as by the. rack H and pinion I the plateholder D receives its reciprocating rotary motion, (secondly describedas inthe nature'ofthis inventiom) the holder D is squared or arranged with a slot .andfeather-keso that the pinion I may turn the same, at the same time allowing the plate-holder to move longitudinally at the-impulse-of the'weight D5. Thus, therefore, by the action ofthe ratchet-toothed wheel yl, shaft z, and escapementdevices G, g, g1, the shaft g2 and lever g3, link 7l,- rack H, and pinion I, the -seeond elementary motion is imparted to the holder D, as heretofore stated. l Tor-the lever Y, I attach the arm g4. IThis acts to raise and lower the link K, in accordanceiwith the motion of the lever Y, before explained. The link k, by the joint-link kl, and its connection with the support-block E, acts to turn said support-block about its pin-axlese in F. Hereby, owing to the cylindrical boss around the plate-holder D, the platelholder is turned in-a small angle inA a vertical plane, thereby imparting the third elementary motion recited as in the nature of this invention, whereby the front endo-f the 'plate-holder'and the `nail-plate isn-aised sufficiently to allow the plate -to be turned without hoisting thesame.

Now,as the forward feed of the holder D, owing to the impulse of the weight D, is regulatedby the stop c and the spring a and lever Y,"and as the turning-motion and tipping-motion of the plate-holder'are derived from the same power-source asisthe shearing-motion of theshears B, the `action of the parts, and the resulting feed-motion, must be'iu' accord with the requirements of the nail-machine5 and lastly, thev said elementary motions, combining to form the compound or ,feed-motion, mustoccur in one and the same interval of time, as stated to be in the nature of this invention. v

Having thiis fully described my invention, what claim, and desire -to` secure by Letters Patent, is

1. The support-block E and adjusting-piece F, constructed and'combined substantially as and for thepurposes set forth.

2. The holder D, its boss z', combined with the block E, links K K, arm y, and lever Y, when acting substantially 'as and for the purposes set forth.

3. The-combinationof the adjusting-piece F with the main frame atf, and with the guide-bar j and set- 'screwf when acting substantially as and for the purposes-set forth.- l 4. The combination ofthe pawl y, the wheel y1, and lever Y, substantially vas and'for the purposes set forth. 5. The combination ofthe disk G, pins g, and armsgl, and vert-ical shaft gz, substantially as s et forth.

In witness of said invention I have hereunto set my hand and seal, this 22d day of April, 1867, in the presence of .FRANZ HAIN. [L a] Witnesses z Gao. P. HERTHEL, Jr., T. WHITE.
