WIRE-DRAWING MACHINE.
SPECIFICATION forming part of Letters Patent No. 617,053, dated- Janllafy 3, 1899- Applieation filed February 21,1898. Serial No. 671,161. (No model.)
To all whom it may concern:
Be it known that I, Gorrnnrn SCHEEL, a citizen of the United States, residing at New Brighton, in the county of Beaver and State of Pennsylvania, have invented a new and useful Wire-Drawing Machine, of which the following is a specification.
My invention relates to improvements in machines for drawing wire by which the diameter of a metallic rod may be reduced by elongation thereof until the wire reaches the proper gage; and the object of the invention is to provide a simple and efficient machine in which the wire under treatment is twice subjected to the drawing action of a single die for the purpose of elongating the wire and reducing it to the proper gage.
A further object of the invention is to provide a wire-drawing machine in which the parts are compactly arranged in a simple manner for the proper carriage of the wire to and from a single drawing-die and in which provision is made for the ready and expeditious interchange of drawing-dies withdrawingorifices of varying diameters.
Vith these ends in view my invention consists in the novel construction and arrangement of parts, which will be hereinafter fully described and claimed.
To enable others to understand the invention, l have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure l is a side elevation of a wire-draw ing machine constructed in accordance with my invention. Fig. 2 is a plan View thereof. Fig. 3 is a detail perspective view of the dieholder', and Fig. at is a like view of the drawing-die.
Like numerals of reference denote like and corresponding parts in each of the several iigures of the drawings.
1 designates the bed of my improved wire drawing machine.
2 is the die-holder.
3 is the positively-driven drawing-drum, and 4C is an idler guide-drum by which the wire from the drawing-drum is properly directed and repassed through the drawingdie.
The die-holder 2 is of box form and coml prises a base G and vertical sides 5, having vertical slots 8 extending through their upper edges. A top plate 7 extends across the. space formed between the side pieces 5 and spans the upper ends of the slots 8 and is secured to the top edges of the side pieces 5 upon opposite sides of the slots by suitable fastenings. In order to provide a substantial structure, the die-holder is formed with the base and sides 5 in one piece, the construction admitting of the holder being cast with the slots 8 therein and avoiding subsequent labor and expense, which would result if the parts 5 and 6 were separate and required to be secured together. These .alined slots receive the drawing-die l0, which is of proper dimensions -and form to lit snugly in said slotted die-holder, and said die is designed to be held or secured rigidly and detachably in the holder 2 for the purpose of withdrawing it from said holder, thus enabling the drawing'- dies to be used inter changeably in the machine. Each drawing*- die is provided with two or more drawingorifices 11 l2, which orifices are of different sizes to accommodate the rod of metal on its first passage through the drawingdie for the production of wire of one gage and to enable said wire to be repassed through said die to reduce the wire to the desired gage, said drawing-die being thus adapted to twice receive the wire for subjecting the same tothe treatment necessary to secure the proper gage in the wire. The drawing-die 10 is placed in a vertical position within the die-holder, so that the axes of .the drawing-orifices are horizontal, and the drawing-orifice 12 of large diameter is in a horizontal plane below that of the drawing-orifice of smaller diameter 1l, said drawing-orifices arranged to have their horizontal axes parallel to each other and prefy erably in the same vertical plane.
The die-holder 2 is held or confined on the machine-bed l by a single strong bolt 14, which passes through an aperture in the base of the die-holder between the sides 5 thereof and near the front receiving end of' said holder.
The drawing-drum 3 is supported on the base in rear of the die-holder and to present its annular or cylindrical surface on a plane a little to one side of the drawing-orifices in the die 10. This drawing-drum is shown as lO I provided near one end with a cylindrical enlargement 15, below which is an annular protruding flange 16 on a plane below the hori- Zontal line of the drawing-orifices in the die, thus preventing the wire from becoming entangled with said drum. The drum is carried by a shaft 17, suitably mounted in the bed and operatively connected with a driving mechanism, (not shown,) by which the drum 3 is properly driven to draw the wire through the die and coil the same on said drum 3, preliminary to delivering the same to the idler-drum 4 and to the take-up drum or reel on which the wire is to be coiled, the last-named drum or reel not being shown, because it is ordinary in the art.
In operation the metallic rod of the proper size is first passed through the large drawingorifice 12 in the die and connected in a suitable way with the drawing-drum This drum is driven by the driving mechanism to coil the Wire a number of times thereon, after which the drum is thrown out of gear, a couple turns of the wire on the drum are removed therefrom, and the Wire is carried around the idler drum and through the smaller drawing-orifice 11, the free end of said wire being then attached or connected to the drum. The drum is now positively driven to draw the wire through the orifice l2 for the initial reduction and elongation of the wire, the wireis coiled a number of times on said drum7 thence delivered around the idler-drum and carried through the smaller orifice 11 in the die, and finally the wire is coiled around the drawing-drum The wire is thus drawn twice through the single die to be subjected to the drawing action of the orifices therein of different diameters, and the idler-drum serves to properly direct that length or section of wire which is to be carried from the drum and repassed through the die to reduce the wire to the desired gage.
In my machine the idler-drum is situated 4adjacent to the receiving end of the dieholder on the opposite sidethereof from the drawing-drum, and this idler-drum is disconnected froni the driving mechanism of the machine, so that it rotates or turns freely under the contact of the traveling wire with the same. This idlerdrum is preferably flanged at its ends to prevent the wire from being displaced thereon, and said drum is mounted loosely on a vertical stem or spindle 18, which is fixed to the bed 1 and provided with collars or nuts 19 to restrain the idler-drum against endwise displacement on said spindle or arbor. The die 10 is removably clamped in a fixed position within the die-holder by fitting it in the slots 8 and employing the clamping-screw 13, thus permitting the die to be readily removed and replaced by another die or dies having drawing-orifices of different sizes adapted to reduce and elongate the wire to different gages.
It is evident that changes in the form and proportion of parts may be made by a skilled mechanic without departing from the spirit or sacrificing the advantages of the invention.
Having thus described the invention, what I claim is- A wire-drawing machine comprising in its organization a bed,a vertically-disposed drum centrally located at one end of the bed and having its lower end hanged and enlarged contiguous to the flange, actuating mechanism for the drum, a flanged guide-drum vertically arranged at the opposite end of the bed, a box-shaped holder secured to the bed at one side and at a point between the guide and drawing drums, said holder having vertical slots extending through the upper edges of its sides and alining transversely, a top plate spanning the slots and extending across the space formed between the slotted sides and firmly attached to the upper edges of said sides upon opposite sides of the vertical slots, a die slidably mounted in the slotted sides of the holder and havingdrawing-orifices of different diameters and vertically disposed, and a clamp-screw fitted to the aforesaid top plate and adapted to clamp the die between the base of the holder and the said clampscrew, substantially as set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
