TlldIItOVED` BAIL-MAKING MACHINE.

TO ALL WHOM IT MAY CONCERNE Be itknown that I, HENRY C. Winnen, of Ashby, in the county of Middlesex, and State ofMassachusetts, have invented anew and useful Machine for Making Bails, called VWilde'rs Automatic Bail-Machine;and I do hereby declare that the following is a full, clear,`and exact descptiony of the construction and operation of the same, reference being had to the annexed drawings, making a part of this spcification, in whichp Figure l is a top view. Theblack lines represent the parts-above the bed-piece, and the red lines show the relative position of the parts below the bed-piece.`

Figure 61's an edge view, representing the bevelled gear m', the vspurgear l?, thc washer and screw n. n', the shaft E E, the ratchet-wheel Q, and the catch dropped between its notches. V

Figure?A is a viewrcpreseuting the'vibratingl shaft J, the lever g, and its projection, o', the pivot o,`tl1el spring p, the arm t', the pivots t l, the pins jj, and the gear'vt.

' Figure 8 represents a. buil.

U is the bail-wood, and T T the hooks.

The edge of the spring-stop() (iig. 2) projects above the highest pointl of the incline t, against whichthe catch t' `(fig. 6) is brought by the rotation of the gear P. The catch t' passes freely through the gear P, and so fargfroni its centre that when it is forced down by thespring tu, (fig.,1,)a part of its width falls Without the circugtiierence of the ratchet-wheel Q, which is iirmly secured to the shaft E E, (iig. 6,) and revolved with it.

if The gear is fitted loosely to the shaft E E, but,I when vthe shaft E E revolves, the friction of the ratchetwheel Q and the washer '/t, which is regulated bythe screw n', is suihceut to hold the catch? against the spring- Stop C,`(iigs. I and 2.) V m v The bent lever B (g.41) is free'to vibrate upon the pivot v just enoughA to remove the spring-stop() and incline t from contact witlrthe-cateh t', and is held in lposition by the spring x, when not working, as hereafter described. K

` The gauge a sodjusted by itsA shank, a', and is secured by the set-screw I). The vibrating armsX X', being'suppcrted bythe pivotsb b2, are free tovibratc. Y

The cutter-plate Dis adjusted by the fastening-screws' e e passing through tlie'slots e e, and supports the hardened-steel ring G and. the lever O C, which is free to vibrate upon the pivot f, and is held imposition by .the spring It, when not working, as'hereaftcr describe-(l. v

' The tunnel`H, (ig.f4,) being in sections, which are attached to the levers I Ig, one of which rests above and the other below the arm X', (iig. 1,)'is held together by the spring q, (fig. 4,) when not working, as hereafter described 4 w 'The stationary tunnel 'S (tig. 1) is slotted through t-hc side nearest the former V. ',Ihc grooved roll O', being supportedhy the lever Z, which lis free to'vibratc upon the pivot u, is adjusted by the screw L.

The hanger m{ig. 5) supports the pivot l, upon which the gear nrevolves. The pivot k, (figs. 5 andv7,) which supports the lower end of thevibratingshaft J, rests in a socket within the circumference ofthe pivot Z, but not in its centre. The lever gis secured in a slot'running lengthwise of the vibrating shaft J by the pivot o, upon which it is free to vibrate. The spring p presses back the lever'g, when not working, as hereafter described, so as to hold the-projection ol in the hardened-steel die F, and thearm t', being attached to its lower end, is drawn into the vibrating shaft J, so that a circle scribed by its outer end cannot intersect the circle scribed bythe pins jj.

The arm e (tig. 1) is firmly attached to'the vibrating shaft J, near its upper end, and vibrates with it.

One end ofthe spiral spring 7L(ig. 5)is attached to the bed-piece A A, and the other tol thevibrating shaft J, which, when not working, as hereafter described, is thereby turned, so as to hold the arm c (iig. 1) against the spring-stop W. The centre of the'circular edge of the die F is concentric with the vibrating shaft J, to the upper end of which it is firmly attached, and vibrates with it. Ther die F has a. circular opening through it, upon a level with the upper end of the vibrating shaft J, s uiciently large to freely receive a bail-wire. The front side of the die F has the corner of the circular openingrounded, so that the bail-wire is more readily thrust into it, but the back 'side has 4its cerner sharp, so as to catch the end of the bail'wire, and prevent its slipping from the die while being hooked, as hereafter described.

The guide y is secured in position just in front of the die F, and, withthc end of the vibrating` shaft J, forms a right-angled corner, which serves to'guidethe bail-wire into the die F.

To explain the operation-of my invention, suppose .power applied to the pulley Y, (figs. 1 and 5,) giving continuous rotation to the shafts D D, E E, the gears n m m m', and the washer and screw n n', while all other parts remain at rest, except as Ahereafter described. Having placed a skein of bail-wire upon a reel, at a convenient distance from the machine, pass one end between the groovcd rolls O O O', (fig. 1,) then, with the left hand, place a bail-wood longitudinally between the spring-supports R R, and with the right hand turn the crank z, when the action of the grooved rolls O O O will draw the wire from the reel, straighten and passit through the ring G to the tunnel H, which will guide it through the bail-wood to the tunnel S, which will guide it to thc gauge a, which is pressed back by the wire j ust enough to move the incline t from under the outer edge of the catch r, (figs. land 6,) which is, by'thc spring w, forced dowubetween the notchesv of the ratchet-wheel Q.

The connection thus effected with the continuous rotating parts, revolves the gears P P in the direction indicated by the arrows thereon. y i l The 4cutter dl(igs. 1 and 3) is, by the action of the Apin E against the lever C C, forced ragainst the wire, close lto the ring G, so as to cut it in two.

During the cutting of the wire, the position of the arms X X is not essentially changed, but as the gears PP (iig. 1) continue to revolve, the connections A A receive a forward motion, closing the arms X X', so as to bend the wire upon the spring-supports R R and around the farmers V V.

yThe bail-wood U (tig. 8)`is,lfor convenience, a little shorter than the distan-ce between the spring-supports R R, (fig. 1,) but, as the wire is bent upon them, they arepressed firmly against its ends.

As, the wire passes from contact with the gauge a, the incline t and spring-stop C (figs. 1 and 2) are, bythe spring x,returned to their former position, close to the ratchet-wheel Q.,

The wire is fed from theA tunnel H, (tigs. 1 and 4,) as the pressure of the arm X against the bevels upon the levers I I separates its sections.

As the revolution of the gears P l?l is continued, (fig. 1,) the arms X X' are drawn. back, the tunnel H closed, and the catch 1' (figs. 2 and 6,) raised above the ratchet-wheel Q, by its outer edge sliding upon the incline t, (figs. 1 and 2,) which breaks the connection with the continuous rotating parts, so that the gears P P', the arms X X', and other parts remain in the position shown by iig. 1 until another length of wire suicient to maken bail is forced against the gauge a, as before described.

` For convenience, I shall eallthe partially-*formed bail, wire, the cndsof which, being successively thrust into the die F; (figs. 1 and 5,) are hooked, as shown by iig. 8 at T T'. Asthc wire enters the die F, the lever g iigs. 1, 5, and 7) is pressed back, which extends the arm i from the shaft J, so that a contact with either one of the pinsjj turnsit half way round, and, as it turns, the wire being in contact with the guide y, (fig. 1,) is bent around the circular edge of the die F.

The range of contact with thc pins jj', (figs. 5 and 7,) resulting from the cecqitri'city of the shaft J with .the gear n, is passed by the arm -z'when the shaft J has made a half revolution, and the strain of bending the wire ceases, so that, by.a continuance of the thrust which places the wire in the die F, it is removed there to the incline s, (iig. 1,) which raises it abovcan'd free from the guide y.

As the wire passes from the die F, the spring'p (fig. 7) returns the lever g toits former'position, drawing in the arm 17,50 that it cannot catch against the pins jj while, with the shaft J, it is by th'c spring 1;(g. 5) being carried back to its former position.

The arm c, (iig. resting against the spring-stop W, cau'ses the shaft J and its attachments to remain in the position shown by iig. 1 until another wire is thrust into the die F, as beforedesc'ribed.

What I claim` as my invention, and desire to -secure by Letters Patent, is-

1. The spring-snpports R R, so arranged with formers V V and vibrating arms XeX, or their equivalents, as to receive the pressure of the wire at the ends of the bail-wood, while being bent, as described, and for the purpose specified.
