BAIL-MAKING MACHINE,

SPECIFICATION forming part of Letters Patent N 0. 788,817, dated May 2, 1905- Application filed June 17, 1903. Serial No. 161,766.

To all 1071,0711, it may concern:

Beit known that I, O'rro S. BEYER, a citizen of the United States of America, and a resident of East Rutherford, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Bail-Making Machines, of which the following is a specification.

My invention relates generally to wirebending machines, and has more particularly reference to bail-making machines.

The object of my invention is the production of a machine which will automatically and efficiently form bails for pails, kettles, &c. ,with inwardly-turned end hooks, the present case being a sister application to one filed by me on the 2d day of January, 1903, Serial No. 137,440.

I shall describe a machine of this character embodying myinvention and afterward point out the novel features in the claims.

The wire-bending mechanism consists, essentially, of a passive and an active wire-bend ing member. These members are made in various forms, depending upon, the kind of bail desired, and are provided with auxiliaries in order to obtain the proper effect. The passive wire-bending member is conveniently in the form of a die-block of a suitable contour, normally stationary, but capable of a movement with the active wire-bending memher to effect the proper operation. The active wire-bending member is conveniently in the form of two pivoted jaws of a contour corresponding to the die-block and adapted to clasp the same to effect the proper bending of the wire. The jaws are made to clasp the dieblock by means of two adjustable rolls usually mounted on the framework. while the two jaws are brought into operating position by means of a slider moving in the bed of the machine.

The wire-feeding mechanism may be of any suitable construction and is inthe present instance substantially the same as the one shown in the application previously referred to.

My invention further consists in the general arrangement and combination of parts and features of construction, as will more fully hereinafter appear.

In the drawings I have embodied my invention in a suitable form; but changes in construction may of course be made without departing from the spirit of my invention.

In the said drawings, Figure 1 is a plan view of a machine embodying my invention. Fig. 2 is a broken sectional view on the line m :1: of Fig. 1. Figs. 3, 4:, and 5 are detail views of the wire-bending mechanism, illustrating the different steps in the operation of bending a bail. Fig. 6 shows the bail produced by this form of bending mechanism. Figs. 7 and 8 show a modified form of wirebending mechanism. Fig. 9 shows still another modification.

Similar letters of reference indicate corresponding parts in the different views.

A indicates a bed or framework of any suit able construction supporting the various parts of the machine.

Bis the wire-feeding mechanism, and D the wire-bending mechanism.

Power is derived from the shaft A, mounted transversely of the machine and carrying the pulley a and pinion a, the latter meshing with the spur-gear a on the main cam-shaft 'A, extending parallel with the shaft A. A is an auxiliary cam-shaft operated from the shaft A through the train of gears a", a and a.

The wire-feeding mechanism is in this instance of the conventional type and consists of the usual two feed-rollers I), (one of which only is seen,) operated conveniently from the main shaft A by means of the crank t rack Z1 pinion b, bevel-gears If and I), and the usual ratchet mechanism incloscd in the casing 12 to impart an intermittent progressive motion in one direction only to the said feedrolls in a well-known manner.

On either side of the bracket (0 are two sta tionary guides 0, preferably comprising pendent arms having perpendicular slots 0 open at the lower end, or they may be described as bifurcated pendent arms.

Mounted on the rock-shaft 0 are two arms 0, having-slots 0 open at the ends, constituting movable guides for the wire. These arms are located almost at right angles to the stationary guides 0 and on the outer side of the said guides. These arms are normally held in an upper position by means of the spring 0 attached to the framework and to the arm 0 of the rock-shaft 0 When in this position, they intersect the stationary guides at a point in alinement with the feed-path of the wire-feeding mechanism. The rock-shaft 0 is operated from the cam 0 on the shaft A by means of the roller 0 and lever 0 b is a cutting device for the wire-feeding mechanism of a well-known construction, operated by means of the cam b on the shaft A roller 5 and lever I). This lever b is pivoted to the bracket I) by means of the bolt 6, while the bracket is adjustably mounted in a manner well known on the way I) by means of bolts 6. hen the position of the bracket is changed, the cam b of course also has to be adjusted correspondingly on the shaft A A stop F is located on the other side of the machine and at the end of the feedpath of the wire-feeding mechanism, against which the wire is fed. This stop is adjustable on the way o by means of the thumb-screw 6 and the holes Z). By adjusting this stop and the cutting device different lengths of wire can be obtained. 6 indicates an arm centrally pivoted, as at 6 and adapted to pinch the wire between the head 6 and the face 6 during the cutting operation, it being operated from the cam 6 by means of the rollo The bending mechanism consists primarily of a passive and an active wire-bendingmember D and D Describing first the form shown in the general views and in Figs. 3, 4, and 5, the passive member is composed of a die-block (Z substantially circular shaped and suitably mounted on the bed.

(Z represents two recesses at the end opposite to the one adjacent to the active wirebending member. The said die-block is,moreover, provided with a rod (1 carrying a flange CZ, which bears against a compressible rubber bumper (Z carried on the bracket 6 33 of the framework.

Ll is a bolt passing through the slot [Z of the die-block (Z 6Z denotes an auxiliary to the passive wirebending member, forming in this instance two fingers (Z attached upon the block (Z so as to have a slight play and located opposite to the recesses (Z of the die-block (Z The active wire-bending member is characterized by two pivoted forming-jaws d of a contour corresponding to the contour of the dieblook and mounted in this instance upon the slide (Z in the guideway 6Z8, formed in the bed or framework. The slide (Z is operated from the crank-pin (Z carried on the crankshaft A the lever (Z forming a suitable connection between the slide and the crank-pin. On the framework on either side of the dieblock are located the rolls cl, adjustable by means of the hand-wheels (Z by means of which the jaws are caused to clasp the dieblook to bend the wire as they advance toward the same.

E is a stripping mechanism comprising an arm 6, mounted on the rock-shaft e and carrying a transverse piece 6 extending over the die-block, and provided with two strippers 6*, shaped to conform to the contour of the said die-block. The rock-shaft e is operated from the cam e on the shaft A by means of the forked lever 6 carrying the friction-roll e and connecting with the crank e on the shaft 6 The operation of the device is as follows: The movable guides 0 being in their uppermost position, the wire-feeding mechanism is operated, feeding a strand of wire through the movable guides 0 and the stationary guides 0, whereupon the arm 5 descends, pinching the wire while the cutting device 6 is operated, thereby severing the wire. The movable. guides 0 are now operated, carrying the strand of wire through the slot 0 until the die-block is reached. The slide (Z now advances, carrying the two forming-jaws (Z with it, which latter upon coming in contact with the rolls (i are caused to clasp the wire against the die-block and around the same, assuming the position shown in Fig. 4. \Vhile the wire is being bent around the dieblock and until the position shown in Fig. 4 is assumed the said die-block remains stationary. Upon the further forward movement of the slide (Z the jaws having reached the end of their stroke,the die-block will move a distance with the said jaws, when the pressure becomes strong enough to overcome the tension of the rubber bumper. The effect of this is to move the die-block toward the auxiliary, the two fingers of which encounter the ends of the wire, so as to bend the same around the projections d forming the recesses (Z as shown in Fig. 5. Upon the retrograde movement the rubber bumper will of course return the die-block to its normal position. The slide (Z thereupon recedes and the stripping mechanism B descends, removing the finished bail from the die-block.

Numerous variations are of course possible, depending upon the kind of bail desired. Thus, in Figs. 7 and 8, the end projections 42, carried by the die-block, are shaped slightly different and located nearer together, while the auxiliary in this instance consists of two formers (Z having jaws to engage the ICC projections d so as to bend the end hooks, which auxiliary is slightly movable with the said die-block by means of the pin (Z moving in the slot d on the block carrying the auxiliary. Again, in Fig. 9 the die-block is formed with square incisions d at the end opposite to its auxiliary cl, the latter consisting in this instance of a square block which bends the ends of the wire around the projections d. The style of bail produced by the bending members in this instance is of the style shown in Fig. 6 and is characterized by inwardly-turned end hooks.

Having thus described my invention, what I claim is 1. In a bail-making machine, the combination of a passive wire-bending member normally stationary and an active wire-bending member movable toward and away from the passive member for bending a wire into bail shape, an auxiliary for forming the bail with in wardly-turning end hooks,and means whereby the passive member is caused to move a distance with the active wire-bending member.
