IMPROVEMENT IN NUT-MAKING MACHINES.

Specification iorining'pnrt of Letters Patent No. 45,146, dated December ifi, IBG-i.

To all whom it may concern:

Be it known that 1, LEWIS WEcKEssER, of New Haven', in the county of New Havenand State of Connecticut, have invented a new and Improved Machine for Making Nuts; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which.-

Figure 1 is a pian or top view of my invention; 1"ig.2, a vertical section of thc same taken in the line a.' Fig. l; Fig. 3, a vertical section of the same taken in the line y y, Fig. l; Fig. 4, a vertical section ot' the same 'taken in the line z z, Fig. l Fig. 5, a vertical section ofthe saine taken in the line z e', Fig. 1; Fig. 6, a vertical section of the same taken in the line x w", Fig. 7; Fig. 7, a detached view ot' two wheels pertaining to the same.

Similar letters of reference indicate like parts.

This invention consists in a novel and sim, ple device for gaging the bar from which the blanks are cut previous to the cutting ott' of each blank from the bar, so as to insure the blanks being of the same size or of uniform dimensions.

The invention also consists in the peculiar construction and arrangement of parts Whereby the whole opera-tion of punching and forg-Y ing the blanks is brought within a very limited space and a very simple device obtained for the desired purpose, and one possessing a num ber ot' advantages, as hereinafter set forth.

A represents a bed-plate, at one end of which there is a driving-shaft, B, from which all the workingparts of the machine are driven.

C is acum, placed on oneend ofthe shaft B, and formed ot' a wheel provided with a zigzag groove, a', in which a 'friction roller, b, on an arm, D, works, said arm being attached to a slide, E, which works within a grooved bar, F, att-ached to the bed-plate A. The slide E has a reciprocating motion imparted toit by means of a cam, C.

G is a rod or shover, which is fitted horizontally in the slide E, and is retained therein by a catch formed of a pin, b', and a spring, c, the pinbeing attached to the end of the spring, and the latter having a tendency to keep the pin ina notch, d, in the rod or shovel',

as shown in Fig. 2. In case the rod G meets with any resistance in the prosecution of its work, the pin b will slip out of the notch d in the rod and prevent the latter from being bent or broken.

H represents a cutter, which is fitted in a vertical guide, e, on the bed-piece A, and is operated by means of a lever, I, from a cam, J, on the shaft B, said cani forcing down thc cutter, while a spring,f, raises it. (See Fig. 3.) Y At one sideot' the guide e there is a lever, K, havinA its fulcruin at. g. t. This lever is operated y means. of a projection, h, at one side of the cutter H,nearits upper end. (Sec Fig. 2.) This projection actsupon the lever KA before the cutter acts upon the bar from which the blanks are cut,.aud causes the bar which is placed underneaththe cutter to be compressed to a certain or uniform width previous to each cut. therefore causing the blanks to be cut oi' from said bar of equal size. The lever K presses the bar against a plate, t', and when a. blank is cut oli' by the cutter the former drops down below said plate and in line withran opening or passage, j, in a. plate, k. This passage j is made ot'spiral form, and the blank is forced through it by the rod -or shover G, which is moved at the proper time by the cam C, operating the slide E. The spiral opening or passa-ge j turns the blank from a horizontal to an edgewise position and forces it into a narrow chamber, L, the bottom otl which is composed of an adj estable bar, m,

which is narrower than the chamber L, to admit ot' an opening at each side for the escape of scales and dirt or trash. (See more particularly Fig. l.) This harm is rendered adjustableby means of set-screws An inpassin g through oblong vertical holes o o in bars p p, as shown in Fig. 2.

The blanks are punched and their face sides rounded in this chamber I. The punch L is operated by a cam, M, on the shaft B, and it works through a xed guide-plate, g, .and within a box, i", which has also a sliding motion, and is operated from the sanne cam M. The box fr grasps the blank and holds it in a proper relative position with the punch before the latter is shoved through the blank,thereby insuring the latter being punched centrally.

The facing punch or tool N is operated from a cam, O, on the shaft B, and simply givesarounded or convex form to the face side of the nut. The blank is forced from N, directly in front of a slide, P, which is operated from a cam, Q, on shaft B.

' The slide P shoves the blank on one ot' -a series of arbors, B, iitted radially in a horizontal wheel, S, on the bed-piece, and in such a manner that they may turn in said Wheel. These arbors have each a square, s, at their inner ends, upon which springs t on the Wheel S bear, said springs preventing the arbors from turning casually, and each arbor has a small spur-wheel or Wiper. u, upon it, which adjoin small circular collars r. (Shown in Fig. 1.)

The Wheel S is placed on a shaft, T, which extends down through the bed-piece A, and has twowheels, U U', upon it, one of which, U,is provided with pendent teeth w at equal distances apart, and the other provided with notches aX in its periphery, into which apawl, w, catches, to prevent the casual turning of the Wheel S.

V is a rod having a hook, be, at its inner end to Vengage with the teeth w of wheel U and rotate the same. This rod V is operated from a cam, W, on shaft BX, the return motion being given it by a spring, 0X. (See Fig. v6.)

X represents a 4shaft underneath the bedplate A, which is driven by gears dx froma shaft, Y, the latter being` driven by gears eX from the shaft B. On the outer end ot' the shait X there are placed two wheels, Z Z', one of which, Z, is provided with teeth fx, and the other, Z', with projections gx, a'projection being bythe side ot' each tooth'. (See Fig. 7.) The teeth fx of the wheel Z serve tol rotate the arbors B, said teeth engaging with the spur-wheels or wipers u, while the projections 11X raise the arbors to free the blanks on them from the bed-piece. rThe blanks are forged on their edges, -while on the arbors 1% by means of ahammer, A',

.operated from a cam, B', on the shaft B, and

each arbor, by the mechanism above described, is turned three times, so as to cause all the sides of the blank to be smoothed or forged under the action of the hammer. The wheel -S is turned after each blank is 4thus forged by means of. the rod V acting on the teeth w ot' wheel U, and by this movement of the wheel S the forged bla-nk is brought Within recesses in plates he' at the end of a slide, C', which is operated by a lever, D', and a cam, E', onthe shaft BX', driven by bevel-gears from shaftB.- The plates hx draw the forged blank ofi' from its arbor R While asucceeding blank is being brought under the hammer A',

and.V the blank is drawn by the plates hX' over a hole, i", through which it falls intoa passage,

jx, of spiral form, and is forced through said passage by a rod, E', into a chamber, k", the spiral passage fix, turning the blank from an edgewise to a dat position, so that it may receive a iinishing-strokefrom a hammer, F', operated from a cam, G', on shaft B. The

ber la* by means of a forked plate, H', operated by a cam, I',on shaft BX.

' Thus by this arrangement I obtain a nut-v ma'chine which is very compact, and has all its parts exposedto View, so that the attendant can see the Whole operation throughout.

Having thus described my invention, Iclaim as 'new and desire to secure by Letters Patentf l. The lever K, arranged relatively with the cutter H, and to operate in connectionthereforth.

2. The securing ot' therod or shover G in its slide E by means ot' the spring c and pinor substantially as shown, to admit of the rod b shovel', in case ot the lattcr meeting with any resistance in its Work, becoming disengaged from the slide, as herein described.

3. The spiral passagesj j", for the purpose of turning the nuts, respectively, from a flatwise to au edgewise position, and vice versa, as described.

4. The adjustable barm, forming the bot-` tom of the chamber Z, and of less Width than the same, to admit of the escape of scales, dirt,

Sto., therefrom, as set forth.

5. The combination of the punch L and box as specified.

6. The horizontal. intermittingly rotating wheel S, provided with a series ,of radial arbors, B, to receive theblanks and turn the same, so thatits several sides will be consecutively acted upon by thehammer A', substantially 'as set forth.
