APPARATUS FOR DRAWING WIRE.

SPECIFICATION forming part of Letters Patent No. 424,839, dated April 1, 1890.

Application filed August 26, 1.889- Serial No. 321,960. (No model.)

To @ZZ whom it may concern,.-

Be it known that l, JOSEPH W. WHITE, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and' useful Improvements in Apparatus for Wire-Drawing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains tomake and use the same.

My invention relates to improvements in apparatus for wire-drawing; and it consists in certain features of construction and in combination of parts, hereinafter described, and pointed out in the claims.

ln the accompanying drawings, Figure l is Fig. 2 is a plan.

'A represents a bench for supporting the apparatus, and ll a reel on which is placed a coil of wire that is to be drawn.

C, D, and lE are drums mounted, respectively on shafts C', D', and E', power being applied to each shaft, and the drums are usually rotated at the same speed, although this is not material.

F and G are standards or housings for supporting each a series of dies, respectively f and g, the dies of each series being placed one above the other in the respective housings. Drums C andD are draft-drums, being used solely for pullingthewire through the different dies. These drums have each a series of circumferential grooves, respectively c and d, these grooves being usually something less than semieircular in cross-section. These grooves may be quite' shallow, being intended only to keep the wire in place on the respect` ive drums opposite the respective dies. The finished wire is wound on drum E, this drum having no grooves and the end of the wire being fastened thereto, this drum serving also as a draft-drum in pulling the wire through the last die, and more especially in giving tension to the wire, by means of which tension the diderent coils of wire are succesL sively tightened on drums C and D. The coil of wire having been placed on the reel, the free end of the wire is pointed, so that the end thereof may be passed through the different dies, 'lhe end of the Wire is first passed, for instance, through the lower die f and drawn by hand until there is enough drawn wire to Wrap once or twice around drum D, after which wrapping the wire is passed by hand through the lower die g, and from thence around drum C, and back through the second die f from the bottom, and again wrapped around drumY D, and so on throughout the required number of dies, the wire leading from the upper die f directly onto drum E. Drum E, having, as aforesaid, the end of the wire fastened thereto, pulls the wire through the upper dief, and in so doing tightens the upper coil of wire on drum C, causing the latter to draw the wire through the upper die g, and this in turn tightens the upper coil on drum D, such retrograde action of tightening coils extending throughout the dies and coils on drums O and D, and causing each drum to draw the wires. through the different opposing dies. In placing the wire upon drums C and D, as aforesaid, it is only necessary to draw the wire by hand through the respective successive dies. The drums, being in motion, draw the wires through the dies in which the wire had previously been inserted and wound from thence around the drums. For instance, the wire having been drawn by hand through the first lower dief and passed from thence around drum D, by afterward tightening this coil by drawing on the Wire by hand this drum draws the wire through the iirst die uut-il there is enough slack wire to pass through the lower die g and to wrap around the drum C, after which by again drawing on the end of the wire the two drums O and D draw the wire through the first two dies, and so on. It will be understood that the drums C and D have little or no effect on the wireso long as the coils areloose on these drums, and that the drums only pull the wire as the coils are tightened by drawing on the advance end of the wire, and hence, although the wire is elongated in passing through the respective dies, the slipping of the drum in the diiferent coils of Wire, except as these coils are Vtightened by the draft of the coil next in advance, causes the entire system to'operate automatically.
