SAMUEL VANSTONE, OF PROVIDENCE, RHODE ISLAND.

MA CHlNE FOR BENDING BAILS.

SPECIFICATION forming part of Letters Patent No. 252,551, dated January 17, 1882.

Application filed October 17, 1881. (No model.)

- To all whom it may concern:

-the city and county of Providence, State of Rhodelsland, have invented a new and useful Improvement in Machines for Bending Bails; and I hereby declare that the following is a fnll,clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has rcferenceto an improve ment in machines for bending the bails for buckets, kettles,and other articles; and it consists in the peculiar and novel arrangement of pivotally-connected bending-levers, a reciprocating former, and pivoted arms constructed to form the eyes of the hail, the wholearranged to form the complete bail at one operation, as will be more fully set forth hereinafter.

Figure 1 is a frontelevation of myimproved machine. Fig. 2 is an end view of the same. Fig. 3 is a sectional view of the spring-pressed bolts bywhich the levers bending the eyes are operated. Fig. 4 is a skeleton view, showing the operating devices in the position occupied when the former descends to bend the bail. Fig. 5 is a skeleton view, showing the devices in the position occupied by them when the bail is completed. Fig. 6 is a vertical section on line as w of Fig. 1. Fig. 7 is a skeleton view of the wire-bendingdevices at a point of their operation intermediate of the beginning and tinishing, as shown in Figs. 4 and 5.

111 the drawings, Arepresents the former secured to a reciprocating slide, A, which lies behind the supporting frame orstandard' S, and has a screw-stud, a, projecting forward through a vertical slot, a, in said standard, this stud passing through the former, which is secured thereon by a suitable nut.

B B are the lower bending-levers, provided with the rollers b b and pivoted at 0 0. These le-- vers are connected by springs t t with the laterally-projecting arms 8 s of the standard, the upper ends of the levers lying behind said standard. The rollers b b are in front of the standard and mounted on pins 1) b, which project forward from the ends of the lovers and through the curved slots 12 o in the standards.

0 G are two rests pivoted at the lower end, and kept in position by a coiled spring, 0, as is clearly shown in Fig.2. The upper inner corners of these rests stand under the levers B B and prevent them from descending belowa certain point, except when said rests are removed.

D is a curved pro ection extendlng from the rests C O, and E is a wedge-shaped cam attached to the slide A,and which,on descending, passes behind the projection D and withdraws the rests U G from under the levers B B. allowing the free ends to descend with the follower and bend the bail inward.

, F F are two adjustable guides which project forward from the arms 8 s of the staudard,and

by which the ends of the blank are held and prevented from turning up until the ends are drawn from under the same.

H H are the upper curved bendinglevers, pivoted on a common pivot, h to'the lower portion of the follower I, which is supported by an arm projecting through the slot at from the slide A. The long arms of the levers H H are curved downward, and the short arms curve slightly upward from the pivot, and are provided at their ends wit h rearwardly-proj ecting studs h h, which normally rest in notches h formed in the lower edge of the follower I.

g g are two spring-pressed bolts, with which the ends it h of the pivoted bending-levers H H come in contact as the follower I descends, .80

so as to bend the ends of the bail into eyes by the co-operation with the studs h h of the bending-levers H H, as is shown in Fig. 5. The outer ends of the bolts g are connected by a bar,g and slide in sockets 9 formed at the tops of vertically-adj ustable arms G, which are secured to the laterally-adjustable standards G by slot-and-bolt connection. The bar g is provided with a handle, 9 The follower I is constructed to slide in ways, and is counter- 0 balanced by the weight K. The follower and its sliding carriage may be operated by means of the bars L connecting with a foot-treadle or with any other means for operating the same.

N N are adjustable stops for the bail-blanks, 5

O O are studs projecting downward from arms 1) p, which project laterally from opposite sides of the slide A. At the lower ends of these studs are pivoted rollers O O, which at a proper point in the operation of the machine strike the upper edges of the levers B B, and force said levers dow-nward.

The operation of the machine is as follows: The stops NN being properly adjusted, a blank, as shown at M, (which is simply a wire rod of proper length to form a bail,) is laid upon the rollers b b with the ends extending under the stops F F. The slide A is then forced downward by means of a treadle connected with the bars L L, and the former A strikes the blank and bends it down between the rollers I) b. When the blank is thus bent to the degree for which the wedge-cam E is adjusted, said cam strikes the curved piece D, forcing the rests G from under the levers B B, and immediately following the removal of these rests the rollers O O strike the upper-edges of the levers B B, forcing the inner ends of these levers down and the rollers b 1) toward each other. The former A, in the meantime, having passed below the rollers b b and drawn the ends of the blank from under the stops F I these ends project upwardly between the rollers b 1). Previous to this point in the operation of the parts named the ends it h of thelong arms of the upper bendinglevers,H H, have struck the bolts 9 g and are forced upward, as shown in Fig. 5, throwin g the short arms of said levers downward, so that as the ends of the blank escape from the stops F F and. spring upward they are struck on their upper sides by the studs h h of the short arms of levers H H, and now as the levers B B are further forced downward by the rollers O O, and the rollers b b bend the blank over the former, as shown in Fig. 5, the studs h h, also descending with the slide and follower I, bend the ends of the blank down and around the rollers b I), thus forming the eyes of the bail, as shown also in Fig. 5. The bail is now completed, and in order to remove it from the machine the bar g is drawn outward byits handle 9 thus drawing the spring bolts g into their sockets and from under the ends of the elevated long arms of levers H, so that these long arms fall by gravity to their normal positions and the short arms are raised from in front of the rollers b I). The operator may then seize the lower portion of the bail and draw it off the former, and at the same time the eyes slip off the rollers l) b. A suitable notch, q, is formed in the lower edge of the former to enable the operator to grasp the bail, which having been removed,the parts are allowed to assume their normal positions ready to operate upon another blank, the weight K drawing up the slide, and the springs t t raising the levers B B.

Having thus described myinventionlclaim as new and desire to secure by Letters Patent 1. The combination, with the pivoted levers B B and the levers H H,ofa reciprocating follower provided with the former A, the bolts 9 g, and bearin gs F F, constructed to operate as and for the purpose set forth.

2. The combination, with the pivoted levers B B, provided with the rollers b b and the reciprocating former A, of the rests O 0, constructed to be removed when the former has descended part of its stroke, and thus allow the free ends of the levers to bend the bail over the former, as described.

3. The combination, with thelevers B B and H H and the reciprocating former, of the spring-pressed bolts 9 g, as described.

4. The combination, with the reciprocating former A, secured to a sliding head,and means for forcing the former on the blank, of the hinged lever B B, the supports 0 O, and means for detaching the same, the rests F F, boltsg g, and levers H H, the whole constructed to bend a bail at one operation, as described.

In witness whereof I have hereunto set my hand.

SAMUEL VANSTONE.
