IMPROVEMENT IN DEVECES FOR BENDING BAILS.

Specification forming part of Leiters Patent N0. 149,076, dated March 3], 1874; application tiled September 22, 1873.

To all whom it may concern:

Be it known that I, SYLvEsrnn E. SMITH, of St. Louis, Missouri, have'invented an Improved Machine for Making Bails, Handles, &c., of which the following is a specification:

This invention relates to hand-machines for the making of rings, hooks, staples, fastenings, and the like, especially for ears and bails for pots, buckets, and similar vessels; and consists in certain details of construction, which will be fully described hereinafter.

Of the drawing, Figure l is a plan view; Fig. 2, a sectional elevation at line x m,- Fig. 3, a perspective view of hand-lever with follower attached, Figs. 4 and 5, perspective views of dii'erent sizes of mandrels used; Fig. 6 being a perspective view of shoulder-stop.

A is the circular body or frame, properly mounted on abcd-plate, or secured to a support. a is the shaft, its upper end having a socket to receive, and in which the shank of a bolt or mandrel, al, is placed. (See Figs. 2, 4, 5.) AThe mandrels al can be of different size-s, according to the thickness or diameter of the metal. B is the handle or lever, formed to have a curved journal-bearing, I), and, also, the joint-bearings b1, at its front end, (see Figs. 1,2, and 3,) the object of the bearing b being to pass through it the shank of the mandrel al, and to so journal the hand-lever B to the shaft a as to turn in either direction. For this purpose, to secure the mandrel a1 in the socket of shaft a, a small pin, a?, is passed'through a corre sponding groove with which said mandrel is provided. (See Figs. 2, 4, 5.) The hand-lever Bis thus secured between the respective shoulders of the mandrel al and that of the top of the socketed shaft a. In the joint-bearings b1 of the hand-lever B I provide a roller, b2. Said roller can also be of different sizes (see Fig. 2) to suit the varying diameter or thickness of the iron or wire; and,in order to allow same to be passed through and between the mandrel al and roller b2, as will hereinafter appear.

To make devices where a shoulder is required, I have provided the machine with the following improved shouldenstop The shoulder-stop should possess great bearin gstrength to resist the strain brought against it. For

this purpose I cast, or otherwise make, to forni part of the frame A, an inward-proiecting offset, C. (See Figs. l and 2.) The top of the offset O is further recessed, or made to a shoulder or seat, in which the shoulder-stop C is to be seated and secured. (See Figs. l and 2.) The shoulder-stop C is of the shape shown in Figs. l, 2, and 6, terminating in the shoulder-point c, and, further, having an elongated slot, el, the purpose of the shoulder-point being to produce the shoulder in the wire, rod, or work, and the object of the slot cl being to secure, by means of a set-screw, c?, to the shouldered offset C, the shoulder-stop O1 in any adjusted position to and from the mandrel al, as the thickness of the material to be worked requires.

The gage, by means whereof the wire, rod, or metal can be gaged the required distance or length, consists of a spring, D, having one end thereof attached inside the machine A. (See Fig. 1.) The loose end of the spring D is worked adjustably, by means of a proper set or hand screw, D1, which passes through the frame A. (See Fig. l.) Thus, also, the spring' or gage D can be operated to and from the mandrel al, and the material be gaged for large or smaller di1nensions.`

VThe parts being arranged, adjusted, and secured as described and shown, their operation is therefore as follows: The wire, rod, or the like to bc operated, is placed in line with the shoulder-point c, passed between the roller L2 ofthe hand-lever B and the shoulder of the mandrel al, until one end abuts against the gage D. (See Fig. l.) The hand-lever B is next turned, and, in doing so, its roller b2, operating against thefgaged end of the inserted metal, causes same to follow the circular movement of the said lever until same is estopped by the shoulder-stop G. As soon as the metal is brought by the lever B against the shoulder-point c it will be noticed that same makes and produces the shoulder in said metal required. One end of a bail, With ear and shoulder, is thus made; and the other end can similarly be made by the same 'operation Likewise, staples, hooks, and various fastening devices can, in thelike operation, be quicklymade.

The bails for pots and the like have, as is well known, a semi or part circular shape. To

make this form or curved shape I provide the machine with the devices as follows E repre sents my former.77 Its vertical outer side is slightly grooved, as at e. (See Fig. 2.) It furheris formed to have bearings atea', by means whereof it can be bolted to the top or alongside of the machine. In. conjunction with the former 7 E, I provide the hand-lever B with a follower, F. The follower F is of the constructive shape clearly shown in Figs. 2 and 3, so as to have the collar-bearing j' and jointbearing j", the object of the collar-bearing j' cular-shaped; therefore, one end or ear of the bail, wire, or rod previouslymade is placed and held by a pin or lug, f4, at one end of former E, (sce Fig.1,) the other end or part being placed between said former and the roller f ofv the follower F on hand-lever. Then by turning the hand-lever B, and thus causing the roller f 3 to traverse the curved former E, the bail, wire, or rod is bent er curved to the proper form.

l. In combination with the casting A, the adjustable shoulder-stop Cf, mandrel al, lever B, and roller b2, as described.

2. The frame F, having an orilioe adapted to receive the shank of lever B, and also setscrew f2, arms f1 fl, and roller f, as and for the purpose described.

In testimonyY of said invention I have hereunto set my hand.
