SPECIFICATION forming part of Letters Patent No. 554,444, dated February 11, 1896. Application filed July 9,1895. Serial No. 555,394. (No model-) To all whom it may concern.-

Be it known that 1, DAN L. HILL, a citizen of the United States, residing at Keene, in the county of Cheshire and State of New Hamp shire, have invented a new and useful Machine for Making \Vire Handles, of which the following is a specification.

This invention relates to machines for bending wire bails for buckets, pails, tubs, and like packages generally provided with wire handles or bails to facilitate the carrying of the same.

The object of the invention is the provision of a machine which with slight modifications can be adapted for forming a variety of handles and bails and for bending the extremities of the said bails to any required angle or into hooks or eyes, as required, and to suit the means employed for fastening the said bails or handles to the pails or packages for which they are designed.

Further objects and advantages will become apparent on reference to the following description and the accompanying drawings, in which- Figure 1 is a top plan view of a machine constructed in accordance with and embodying the principles of the present invention. Fig. 2 is a front View thereof. Fig. 3 is a detail section on the line X X of Fig. 1, looking in the direction of the arrow.

Fig. 14 is a detail View thereof. Fig. 15 shows a variety of forms of bails and handles adapted to be formed by a machine constructed in accordance with the present invention. Fig. 16 is a detail view of an armrfor bending the wire about the former.

Similar reference-numerals indicate corresponding parts in the various views.

The bed 1 has brackets 2, in which is journaled a shaft 3 adapted to be driven in any convenient manner and from any suitable source of power, and for the sake of simplicity of illustration the said shaft is shown supplied with a crank 4 for the application of manual power to drive the same. Mutilated bevel gear-wheels 5 are secured upon the shaft 3, and the cog-teeth thereof are adapted to mesh with bevel-pinions 6 secured upon the rear ends of shafts 7, which shafts are journaled in brackets 8 made fast to the bed 1.

- These shafts 7 incline in opposite directions and are formed 011 their front ends with wirecoilers 9, which will vary accordingly as the ends of the bails or handles are to be simply bent,formed into eyes or fashioned into hooks,

andfas shown,these coilers consist of arms 10,

extending at right angles to the shafts 7, and outward extensions 11 at the extremities of the arms 10. These extensions 11 project across the path of the end portions of the wire and in the rotation of the shafts '7 bend the end portions of the wire about mandrels 12, and to admit of the end portions of the wire being formed into eyes the outer sides of the arms 10 have recesses 13 which receive the mandrels 12, so as to admit of the extensions 11 moving around the said mandrels so as to form and complete the eyes when it is required to form the latter at the ends of the bails or handles. The mandrels 12 are formed at the upper end of plates 14, which are firmly bolted to the brackets 8.

Guides 15 are supported at their outer ends upon standards 16 and at their inner ends upon brackets 17, and these guides curve slightly in the direction of their length and are open at their front sides for the outward escape of the wire when the latter is bent into the required shape to form the completed bail or handle. Formers 18 are located opposite the inner ends of the guides 15 and are secured to the latter by plates 19, and these formers may have any required shape ICC to suit the pattern and finish of the completed bail or handle, and, as shown, are curved so as to adapt the machine for the construction of bails for buckets and kindred vessels.

Levers 20 are fulcrumed near their front ends to the brackets 8 and normally occupy a horizontal position, being supported upon springs 21, which return the levers to an initial position after being operated upon by cams 22 arranged upon the shaft 3. The front ends of the levers 2O operate in the space between the outer ends of the guides and the mandrels 12 and are intended to grip the end portions of the wire between the mandrels 12, overhanging portions of the guides 15, and the extremities of the said levers 20. To prevent any possible slipping of the wire the levers are formed with depressions 23, in which the wire is seated when gripped during the operation of the wire-coilers.

Coil-sprin gs 24 are mounted upon the shafts 7, and are secured at one end to the said shafts and at their opposite ends to the brackets 8, and these springs serve to return the shafts 7 and wire-eoilers 9 to a normal position after the bevel-pinions 6 become disengaged from the cog-teeth of the mutilated bevel gearwheels 5. The arms 10 engage with the upper portion of the plates 14 and limit the back ward movement of the shafts 7, and maintain the wire-coilers in an initial position.

A wire-cutter (see Figs. 1 and 7) is placed in proximate relation to the outer end of one of the guides 15, and consists of a standard 25 having an opening 26 for the passage of the wire and alever 27 fulcrumed upon the standard 25 and having a cutting-edge 28 to co-operate with the cuttingedge atthe inner end of the opening 26, so as to sever the wire. A spring 29 operates upon the lever 27, so as to return the latter to a normal position after being actuated by means of a trip 30 secured upon the shaft 3, and a stop 31, provided on the standard 25, engages with the lever 27 and limits the backward movement thereof and holds it in a normal position against the tension of the spring A stop is located at the outer end of the guide opposite and remote from the wire-cutting mechanism and limits the movement of the wire when the latter is fed into the machine.

The wire-feeding mechanism (see Figs. 1 and 8) comprises grooved

wheels

33 and 34, the latter having a diameter about four times the diameter of the smaller grooved wheel 33 and being secured to a vertical shaft 35,which is journaled is a frame 36. A gear-wheel 37 on the upper end of the vertical shaft meshes with a pinion 38 on a journal of the grooved wheel 33, so as to rotate the latter. A yoke 39 operates in a slot 40 in the frame 36, and its ends bear against the journals of the grooved wheel 33, and a U-spring 41 has one end bearing against the yoke 39 and its opposite end is engaged by a setscrew 42, by means of whichthe tension of the spring 41 is regulated, so as to press the grooved wheel with .place the latter.

a greater or less force against the grooved wheel 34. The setscrew 42 operates in a threaded opening at the end of the frame 36, and is adapted to be turned by means of a wrench or other suitable tool, so as to vary the tension of the spring 41 when required. The grooved wheel 33 is removable from the frame 36, and the latter has notches 43 extending inward from its edges to admit of the free passage of the journals of the said grooved wheel 33 when it is required to remove or re- A plate 44 is secured to the frame 36, and has an opening 45 in the plane of the grooves in the peripheral edges of the

wheels

33 and 34, and serves to receive and guide the wire into the passage formed by the grooves in the edges of the said wheels.

A rack-bar 46 meshes with a pinion 47 loosely mounted upon the lower end of the vertical shaft 35, and is held and returned to a normal position by means of a spring 43. A ratchet-wheel 49 is formed with or secured to the pinion 47 and turns loosely upon the shaft 35, and its teeth are engaged by a spring-actuated pawl 50 carried by a plate 51 secured to the shaft 35, so as to turn with the latter. Hence when the rack-bar 4G is moved rearwardly it will rotate the pinion 4'7, ratchetwheel 49, and cause a corresponding movement of the shaft 35 and its attached parts by means of the pawl 50 and the plate 51, thereby causing a movement of the grooved wheels and 34 and a corresponding feed of the wire. A second rack-bar, 52, is attached to or forms a continuation of the rack-bar 4t, and its teeth occur at right angles to the teeth of the rack-bar 46 and are adapted to be engaged by the cog-teeth 53 at the outer end of a toothed segment 54 fixed upon the shaft 3, and by means of which the rack-bar 52 is aetuated in the operation of the machine. guard 55 is secured to the bed 1 and extends over the rack-bar 52 and holds the latter down upon the bed and assists in directing it in its reciprocating movement, and pins 55 are disposed upon opposite sides of the said rack-bar to prevent lateral displacement thereof. The pins 55 have attachment with a plate 55 secured to the bed 1.

By reason of the ratchet-and-pawl connection the rack-

bars

46 and 52 are returned to a normal position under the influence of the spring 48 the instant the toothed segment becomes disengaged from the rack-bar 52 after actuating the latter' to operate the wire-feedin g mechanism.

The wire-crimpers 56 are pivotally connected at their inner ends to a plate 57 supported upon the brackets 17, and have their front ends notched or depressed, as shown at 58, and terminating opposite the inner ends of the guides 15, the lower portion of the said guides projecting and having the notched ends 58 of the wire-crimpers operating thereover. Short bars 5.) have their front ends pivotally connected with the wire-crimpers 5G, and their rear ends are beveled and engaged IIO by cams secured upon the shaft 3, and these bars 59 are guided in their movements upon the plate 57. Plates 61, extending parallel with the plate 57, are firmly and bracin gly attached at their rear ends to the latter, and arms 62 are pivoted at their inner ends to the plates 61 and have elongated openings 63 near their pivotal ends, through which extend pins or studs 6% attached to or forming a part of the short bars 59, and by means of which the said arms 62 are actuated when the short bars 59 are moved forward by engagement therewith of the cams 60. These arms 62 operate over the guides 15, and their outer ends 65 are bent so as to extend across the grooves of the guides 15 and engage with the end portions of the wire forming the bail or handle and remove the latter from the mandrels 12 and from the guides 15 and shape them over the formers 18. Springs 66 are attached to the arms 62 and to the brackets 2 and are designed to return the arms 62 to a normal position and at the same time reset the wirecrimpers 56 and the short bars 59 after the 'latter are disengaged from the cams 60.

Inasmuch as the machine is designed for wiring wooden handles to be used in connection with the bails, it is necessary to provide a hopper for receiving the said wooden handles 67 in a pile, and this hopper is composed of similar vertical guides 68 which extend in parallel relation and are closed in on three of their sides, the open sides facing and being adapted to receive the end portions of the handles. In order to facilitate the introduction of the handles into the hopper the upper extremities of the guides flare. Retainers 69 are located at the lower end of the hopper to support the pile of wooden handles and prevent the latter from dropping therefrom, and these retainers are shaped like a pallet and their nibs operate across the path of the handles and admit of the latter being fed one at a time into proper position for the passage of the wire therethrough in the formation of the bail. These retainers are secured to a shaft 70, which is mounted at its ends in the guides 68. An arm 71 projects from the shaft and is connected by means of a rod 7 2 with a lever 73 near the rear end or side of the bed,

and which has its upper end extending within the path of a trip 7 4 on the shaft 3 so as to be engaged thereby at the proper time for actuating the shaft 7 O to control the feed of the handles 67. A spring 75 operates upon the lever 73 and holds the latter in such a position that the lower nibs of the retainers 69 will extend beneath the lowermost handles and support the pile. The spacers 76, for preventing the crimpin g of the handle or bail close against the ends of the wooden handles, are thin bars which are adapted to reciprocate in grooves 77 formed vertically in one side of the outer walls of the guides 68, and these spacers are tapered slightly at their upper ends to prevent interference with the handles 67 in the vertical movements thereof. The lower edge portions of the spacers are cut away on a curved line so as to facilitate the crowding of the wire beneath the shoulder formed by cutting away the lower portion of the guides 68. a A shaft 7 8 is j ournaled in brackets 79, rising verticall y from the rear ends of the plates 61, and arms 80 extend forwardly from the shaft 78 and engage with projections 81 of the spacers 76, so as to operate the latter. These projections 81 work in slots 82, formed in the outer sides of the guides 68, and limit the movements of the spacers 76. An arm 83 extends rearwardly from the shaft 78 and is adapted to be engaged by a cam 84 on the shaft 3, which cam is so disposed as to actuate the arm 83 and move the spacers 76 across the ends of the handles 67 prior to the operation of the wirecrimpers 56, thereby preventing the crimping of the wire into the end of the handle. A spring 85 is attached to the arm 83 and is intended to return the latter to a normal position when disengaged from the cam 84.

lVhen it is required to form handles and bails and supply the same with wooden handles 67, the latter are fed by hand into the hopper, and the wire for forming the bails or handles is supplied to the

grooved wheels

33 and 34 and fed by them to the guides 15, the stop 32 limiting the feed of the wire after a proper length has been fed to the machine. The lowermost wooden handle 67 will occupy such a relative position that the wire 86 will pass through the longitudinal opening thereof. After a proper length of wire has been fed to the machine the wire-feedin g mechanism will be thrown out of gear and the cutter will come into play and sever the wire to form the bail or handle from the main portion. Immediately after the action of the cutter the wire-coilers will be actuated and bend the extremities of the wire into the required form. The spacers will be projected across the ends of the lowermost handle 67, and the wirecrimpers will operate and crimp the wire at the ends'of the handle. When the crimping is effected the arms 62 will move and shape the end portions of the wire around the formers 18, and an instant later the retainers will move so as to release the completed bail or handle, when the machine is in position for a repetition of the operation just described.

In the modification shown in Fig. 13 the inner end of the shaft 7 will be provided with a pinion 87, which meshes with a corresponding pinion 88 on a vertical shaft, and a pin or stud 89 is eccentrically disposed upon the pinion 33 and is designed to engage with the extremity of the wire forming the handle or bail and bend the same in the form of a hook about the vertically-reciprocating mandrel 90,which is actuated from a suitably-disposed cam on the shaft 3 by means of the lever 91. This is only one of a variety of modifications within the scope of the invention, and by means of which the machine is adapted for forming any one of the variety of bails or handles illustrated in Fig. 15. Therefore it is to be un- ITO derstood that in the embodiment of the invention various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the prineiple or sacrificing any of the advantages of this invention.
