ENT OFFICE OF MANSFIELD, OHIO,.ASSIGNOR ,TO KELSEY-HAYES WHEEL GORPQRATIQN, DETECTED, MICHIGAN, A SORPORA'IIGN OF NEW YORK SELF FEEDIIZG EV/AGING ROLL hubs and rims of wire wheels.

In my formerapplication, bearing Serial Number 270,283, filed Apr. 16, 1928, roll r 'swaging'mechanism is shown by means of which the spokes are propelled through a series of swagingrollers from continuously fed Wire stock and finally are cut therefrom of the'required length and provided with swaged on heads of the required size.

In the presentmachine however the spokes are first cut to lengths and headed and the rolls are provided with spoke engaging means which draw the spokes therethrough, and simultaneously shape them by swaging, so as to at once produce a perfectly formed 5 oke.

The invention includes a hopper from which the spokesare fed by gravity, to a longitudinal platform or support and thence to a pair of swaging rolls, the circumferential edges of which are provided with recesses which engage with the head of the spoke presented, and draw it through the rolls.

A plunger is provided that reciprocates through the bottom of the hopper to project one spoke blank at a time over. said platform into a position where its head will be engaged by said rolls.

Also following rolls are provided which seize and draw the spokes from the swaging rolls.

The second named rolls may also comprise finishing rolls if desired.

With these and other valuable objects in view, the invention includes the combination and arrangement of parts and construction of details, hereinafter described, illustrated in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings, Fig. 1 is a vertical longitudinal section of the device. Fig. 2 is a bottom plan thereof showing the spoke feeding tube in longitudinal sections.

3 is a transverse section of the spoke hopper feeding plunger! 1829. Serial No. 345,437.

Fig. 4 is a transverse section of one of the swaging rolls. Fig. 5 is a plan of one of the completed spokes.

In these views, A is a hopper in which the spokes B-B are received and fed to the platform C in position to be engaged by the plunger D as it reciprocates upon the platform, E and F are the swaging rolls which are provided with grooves G and H in their circumferential peripheries in which the sides of the s'pokesare formed or tapered as desired.

Upon the circumferential edge of the rolls are shown the transverse grooves I and J respectively which engage with the heads K of the spokes in turn as they are propelled forward over the platform by the plunger D.

Forthis purpose the heads K are guided into position by means of the groove L at the outer edge of the hopper, in which they are retained by means of the guide bar M which is attached to the hopper by brazing or otherwise.

The plunger may be operated by means of the arm 0 which is provided with the cap N secured to the arm at P and to which the outer end ofthe plunger is secured at Q.

The cap reciprocates in the open slot R in v the lower part of the hopper wall and is supportedtherein by the bottom wall S of the hopper. i V

This arm is operatively connected with the movements of the'lower roll by means of the pin. T which projects from the outer side thereof and engages on the forward movement of the arm with the groove V in the upper arm W of the forked end thereof.

As the roll revolves to the right as shown by the arrow in Fig. 1, the pin will be released from the groove V and will engage in turn, on further revolution of the roll with the extremity X of the lower arm and will return the plunger to its'original position.

This action will be continued as long as any may alsobe provided with swaging grooves for finishing the spokes.

'Any suitable gearing may be employedto drive the rolls.

' 5 As many pairs of rolls may be provided as are desired to give the spokes the re quired amount of finish.

The position of the cap N on the arm 0 may be adjusted by sliding it along the arm O and clamping it in the adjusted position by means of the screw P, threaded into an arm 0 and passing through the slot N in the cap'N.

Having described the invention What 'I claim as new and desire to secure by Letters Patent is:

r '7 1. In'an automatically acting spoke swaging machine, said spokes being provided with heads, anarrow hopper open at its lower end 9 and provided with guide means for the heads 'ofsaid spokes, a platform under thesaid hop per adapted to receive one spoke-at atime therefromfa pair of swaging rolls adjacent tothe forward ends lofsaid spoke whil lying-fupon said platform, and a plunger hori-. zontally 'reciprOwtable over said platform to move a blank from the hopper and a reciprocatable arm secured to said plunger, said arm being provided with a forked outer end, the upper arm of said fork being provided with a recess in its lower edge and a pin or engaging member secured to the lower swaging roll and revolvable therewith to engage-with said recess in said arm, and vto move said plunger forward, said pin'thereafter: engaging with the lower arm of said fork to move'said arm rearwardly. i

2. In a swaging machine for swaging-head-- ed wire spokes, the combination of a pair of 0 combined feeding and swaging rolls, said rolls being provided a with head engaging means, a'hopper, a platform thereunder upon which said, spokes fall bygravity therefrom, a plunger'reciprocable over said'platform 45. through the bottom of said hopper to project a blank spoke over said platform in such a position that the head o f said spoke will, be engaged by the head engaging means of said rolls, a feeding arm attached at its outer end i 50. to saidplunger and having a verticalv fork' at its inner end, the upper member of said fork being provided with a notch, and a pin operativelyconnected with one of said rolls and adapted to 'engageiwith said'notch once in each revolution of said roll tomove said,

plunger forward, and thereafter to engage with thelower forkf'member on'its return 7 movementand return said arm' and plunger. "In testimony whereof, I hereunto set my handthis 2nd day of March, 1927. g
