MACHINE FOR MAKING WIRE BRACES.

SPECIFICATION forming part of Letters Patent No. 434,311, dated August 12, 1890.

Application filed May 20, 1890.

To all whom it may concern:

Be it known that I, LUNA J. ADERHOLD, re-

siding at \Vaco, in the county of I-laralson tion.

I a machine which will quickly and effectually My invention has for its object to provide operate to bend up and straighten wire into V-braces suitable for use as bed and fence braces; and it consists in the peculiar combination and novel arrangement of parts, all of which will hereinafter be fully described in the annexed specification, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of my improved device. Fig. 2 is a top plan view thereof, illustrating in dotted lines the several positions of the revolving lever during the operation of bending the wire; and Fig. 3 is a perspective view of one of the finished bed-braces.

In the drawings, A indicates a frame or bed-piece, which is suitably fastened upon a bench,table, or standard,upon the upper face of which near one end is mounted to revolve upon a central pivot b a lever B, one end B of which is adapted to be normally over the front edge of the bed-piece A, said end B carrying the twisting devices, hereinafter referred to, the opposite end of which is provided with a vertical roller or guide 0, in advance of which is disposed a guide-finger D, which serves to lead the wire to the roller 0, when the lever B is operated in the manner presently described.

In advance of the twisting devices on the end B and pointing in a direction opposite the finger D is arranged a similar guide-finger E, which serves to guide the free end of,

the wire to the twisting devices, the operation thereof being clearly understood by reference to the dotted lines in Fig. 2 of the drawings.

In operation the wire, which is mounted upon a suitable spool, which, if desired, may be secured on the bed-plate A, or it may be held in any other suitable manner, has its free end passed through a guide-loop F near the inner end of thebed A. It is then passed through a laterally-swinging loop or guide G,

and thence to the bent end h of a crank-shaft H, mounted in bearings h h on the end B of the lever, and which forms one of the twisting devices. By looping said free end of the wire over the said end and holding the end by means of pliersor otherwise and turning the crank-shaft H the said end will be twisted about the wire and a stout loop portion 10 will be formed. By turning thelever B in the direction indicated by the arrow its guide-finger D will force the wire downward in engagement with the roller 0, whereby the wire will be bent at this point as the lever B is turned. As the said lever B continues its revolution, its guide E will engage the wire and cause it to be deflected in the path of the upturned end j of a twisting device J, which consists of a shaft portion journaled on the upper face of the end B of the lever, its outer end being formed of a weighted eranloarm j, which serves to normally hold the endj vertical. As the lever B contines its revolution, the wire will be bent about said end j, and to prevent it coming into contact with the end of the opposite twister I provide a guard-piece L, intermediate of the twister-shafts, which is slightly higher than the arm h and serves to hold the wire from coming in contact therewith during the revolution of the lever, a similar guard-rail H being provided to prevent the wire engaging the end of the section B of the lever. Now when the lever' has been turned back to its normal position the operator grips the wire with a pair of pliers or other convenient tool at a point slightly in advance of its bend about the end j and cuts the wire in advance of the gripping-point. Then by giving the shaft J several turns the endof the wire will be twisted on the parallel portion of the wire, thereby serving not only to form a complete loop, but, owing to the peculiar mannerin which the wire is held, effectually straightening it out.

As the wire during the operation of the lever B is swung laterally between said lever and its point of feed, it is necessary that such wire have free movement and yet be guided at a point near the inner end of the lever, and as a fixed guide at this point would cause the wire to become bent abruptly Iprovide a guide G, which is formed substantially in the the reference to which it will be seen that it con- S1Si'S of a long arm g, a horizontally-extending portion 9 having a pivotal connection in the bed-piece A, and the forward upturned end formed with a loop or guide 9.

Any suitable means may be employed for revolvlng the lever B; but I prefer for simplicityto employ the means shown in the drawngs, which consist in providing-a main shaft Journaled to the projecting end A of the bedplece A, formed with a suitable crank-handle and having agrooved pulleyN mounted thereon, about which an endless chain or .belt is looped, the opposite ends of which are passed over guide-rollers O O and arelooped about a pulley P, mounted 011 the pivotal axis of the lever B, as shown.

From the foregoing description the ad vantages of my improvement will readily appear, and it will be seen that the same may be constructed at a very small cost and can be read- 1ly put up for operation on any convenient bench or table.

Having thus described my invention, what I claim is machine for forming wire braces, comprislng a bed or support, wire-holding de vices, and a revolving lever carrying a fixed gulde at one end and twisting devices at its opposite end, substantially as and for the purpose described.

2. A device for bending wireiuto V-braces for beds and fences, consisting of a base-piece provided with guides for the wire stock and a revolving lever carrying a guide'roller post at one end and the twisting devices at the 0pposite end, and means for operating the lever, substantially as shown and described.

3. In a machine for bending wire braces for beds and fences, the combination, with the bed-piece of the machine provided with a guide or guides for the wire, of the revolving lever B, pivoted on the frame A, formed with a vertical guide at one end and the wire twisters and holders at its opposite end, said twisters consisting of shafts having upturned ends adapted to engage and hold the Wire, said shafts held to rotate on the outer end B of the lever, and means for revolving the lever, substantiallyas and for the purpose described.

4. In a machine for bending wire braces for beds and fences, the combination, with the bed-piece A and guides mounted thereon, of the lever B, held to revolve on said bed-piece A, said lever provided with a fixed guide G at one end, a guide or deflector D, arranged to lead the wire thereto, means for securing one end of the wire to the opposite end of the lever, a twisting device consisting of a shaft J, having an upturned end j, adapted to engage the wire, and means for revolving the lever 13, substantially as shown and described.

5. In a machine of the characterdescribed, the combination of base A, the guides F and G, the lever B, held to revolve on the base A, said lever provided with a fixed guide 0 at one end, twisting devices held on the opposite end consisting of the shafts having upturned ends h and 7' and crank-handles, the guides I, and M, arranged on the end I3 of the lever B, and means for revolving said lever, substantiallyas and for the purpose described.
