ROTARY WIRE DRAWING DIE Filed Feb. 13,1935 2 Sheets-Sheet 2" QETHU C. H/EL/"l,

Patented Oct. 1933 UNITED sTATEs PATENT OFFICE ROTARY WIRE DRAWING DIE Application February 13, 1933. Serial No. 656,611
7 Claims. '(Cl. 205-15) facture, and one which will require but a minimum of attention in use.
A further object is to provide an extremely simple means associated with the die for controlling the rate of rotation thereof.
These and further objects will become apparent after referring to the drawings, in which:
Figure 1 is a plan view of the apparatus of the invention.
' Figure 2 is a side elevation thereof.
Figure 3 is a sectional elevation of the die and its associated bearing, together with the die twister of the invention.
Figure 4 is a view similar to Figure 3 in which modified use of the invention is disclosed.
Figure 5 is an end elevation of the device of the invention. 1
Referring more particularly to the drawings, the numeral 2 designates a frame upon which there is mounted a vertical rotary spindle 3, which rotatably carries a conventional wire drawing block 3*. The drawing block 3 is adapted to draw a wire 4 from the usual reel 5, which is rotatably disposed in a conventional tub 6, and
through a suitable die disposed in its line of movement, in accordance with present practice.
' In the present invention, the wire 4 is made to travel through a wire drawing die 7 which is removablyassociatedwith a conventional ball thrust bearing, generally indicated at 8. The bearing 8 is maintained in position by a bearing holder comprising lower and upper portions 9 and 10,
respectively, which are pivoted at 11 and provided with ears 9 and 10 respectively. The ear 9 is provided with a pivoted bolt 12, which extends through an aperture in the ear 10 and is threaded on its upper end for receiving a wing nut 13, for adjustably clamping the lower and upper portions 9 and 10 together. The lower half 9 of the bearing holder is secured to the frame 2 in any well known manner. Straightener rolls 3 and 3 are disposed adjacent the wire drawing die 7 for assuring the proper alinement of the wire 4 in the .die.
The die twister of the invention is made of suitably' hardened wire, and comprises a straight twister'shank portion 14 which lies in the general plane of the axis of the wire being drawn and which is provided with spaced return bends 14 and 14 The twister is further'provided with an end return bend 14 and an adjacent offset end 14 The oiiset end 14 is secured in a recess 7 in the wire drawing die '7 in any suitable man-' ner. The return bend 14 is disposed adjacent the aperture in the wire drawing die 7, and the straight twister shank portion 14 is bent slightly in order to enable the return bend 14 to lie in a different vertical plane with respect to the return bend 14.
In operation, the end 14 of the die twister is firmly fastened in the recess of the wire drawing die '1, and the wire 4 is passed through the return bend 14 and given one convolution about the twister shank portion 14. The wire is then passed through the return bend 14 and threaded through the aperture in the wire drawing die 7. From the wire drawing die '7 the wire is passed around straightener rolls 3 and 3, and made fast to the drawing block 3 which is rotated in accordance with conventional practice. Due to the angularity of the twister shank portion 14 of the die twister with respect to the die '7, the wire 4 will cause the end 14 of the twister to revolve v about the wire and accordingly rotate the die.
Referring to Figure 4 of the drawings, a modifled use of the invention is shown comprising wrapping the wire 4 twice around the twister shank portion 14, resulting in an increased rotary speed of the wire drawing die 7.
While I have shown and described several specific embodiments of my invention it will be understood that I do not wish to be limited exactly thereto, since various modifications may be made without departing from the scope of my invention, as defined in the following claims.
I claim:
1. In a wire drawing die having a recess, a twister for said die having one of its ends disposed in said recess and adapted to cause the wire to assume at least one convolution before entering said die.
2. In a wire drawing die having a recess, a wire twister having one of its ends disposed in said recess and adapted to cause the wire to assume at least one convolution before entering said die.
3. A rotatably disposed wire drawing die having an offset recess, a twister-member having one of its ends offset and disposed in said recess and provided with looped portions offset relatively to one another and to said offset end for directing 110 the wire to be drawn in anangular helical path before its entrance into said die.
4. A rotatably disposed wire drawing die having an offset recess, a twister member having a central looped portion and an offset second looped portion, and an end portion offset relatively to said central looped portion and disposed in said recess.
5. A rotatably disposed wire drawing die having an offset recess, a twister member having a central looped portion and an offset second looped portion, and an end portion oiiset relatively to said central looped portion and disposed in said recess and said second looped portion.
6. A rotatably disposed wire drawing die having an ofiset recess, a twister member having a central looped portion and an offset second looped portion, and an end portion offset relatively to said central looped portion and disposed in said recess and said second looped portion for rotating the die by the action of the wire traveling therethrough.
7. A rotatably disposed wire drawing die having associated therewith a twister member which is oiTset relative to said wire drawing die and provided with looped portions ofiset relatively to one another and to said die.
