DIE I'IOLDER.

Application filed April 21, 1921. Serial No. 463,168.

To all whom it may concern:

Be it known that LW LLIAM D. Pnnison,

a citizen of the United States, residing at Waterbury, inthe. county of New Haven and State of Connecticuhhave invented certain newand useful Improvements in Die Holders, of which the following'is a specification, reference being had therein to the accompanying drawings. This'invention relates readily removing the die from the lubricant in a wire drawing machine.

The improvements in the details of construction and arrangements of parts will be apparent from an inspection of the accompanying drawings in connection with the description hereinafter contained and wherein a preferred embodiment of. the invention is disclosed for the purpose ofim parting a full understanding of the same.

' In the drawings, I I Figure 1 is a fragmentary plan view of a wire drawing machine; and

Figure 2 is an enlarged perspective view of my improved die holder shown in connection with parts of the wire drawing machineimmediately associated therewith.

This invention is particularly adapted for use with wire drawing machinery, wherein the dies are submerged in a lubricant. This lubricant becomes heated during the operation of the machine to such adegree that 3 it is impossible to place the hand therein. The lubricant at times also becomes dangerous to an operator, because the passageof copper and brass or similar wire there through contaminates it, and septic condi-- tions thus result that make the process of removing a die from. the lubricant by the hand one to be avoided if possible.

' Heretofore it has been the practice to locate the die in the lubricant by placing the hand therein or by a blind search first with a wire or. similar device and then remove it. This is objectionable, not only for the above reasons but because the die is to die holders and it is the principal object of the invention to provide a simple and effective device for frequently found at a point distant from where it is expected to be located and when found it is usually diflicult to get a suiiici'ent hold thereon to lift it from. the lubricant. This diiiiculty is accentuated by the fact that the die is usually cylindrical in shape, or in the form of a frustum of a cone. These, andother objections, I have eliminated with my improved die holder, whereby the die as soon as it is released drops into a holder, the movement of which raises the die out of the lubricant without requiring a search therefor or the necessity of the operator placing his hands in the lubricant itself.

Having more particular reference to the drawings, wherein like figuresof reference designate like parts in both figures, the numeral 10 designates the bed of the wire drawing machine, 11 two wire drawing drums, 12 the die which is held against the fixed the head 14 by the wire ,13 being drawn therethrough'having a slot 15 in the top edge thereof. The bed 10 having. walls 16 upon opposite sides thereof contains the lubricant up to about the top of the die head 14 and thewire 13 is drawn through the die by the rotation of the drums 11. i I

The mechanism above described is all old in the art and constitutes no part of my present invention.

.My improved die holder comprises a box or container 17 which is open on one side and provided with a slot 18in the, opposite side which in its down position is opposite the slot 15 in the die head 14. Lugs 19 are provided on the box or container and through which project the pins or guides 20 fixed in the bed 10, whereby said box or, container is movably mounted in relation to said die head. A lifter 21 provides a convenient means for manually moving said box. It is, of course, possible to make this box or container 17. of any other shape or material, even of wire mesh, if so desired.

When the end of the wire 13 has passed through they die 12 and pressure thereon is released, said die 12 drops into the box or claims.

container 17 and is then readily removed from the lubricant either for threading another wire therethroug'h or for any other purpose, by merely lifting said boxer con-- tainer upwardly by means of the lifter 2i and thus raise said die 12 from its submerged position.

While I have shown the die holder as being mounted upon the pins or guides 20 connected with the bed 10, it is obvious that it may be slidably connected with thedie head 14: and operate equally as well, so therefore desire it to be understood that the mounting means herein shown and describei are only one of the many means that may be utilized for accomplishing this purpose.

Minor changes and alterations may be made within my invention, aside from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended E l/VhatI-claim as new and desire to secure by Letters Patent, is 2- 1-. A device for the purpose described, comprising a box or container separate and independent from the die, and in which the die is held, with means for movably mounting the same upon a wire drawing machine adjacent to the die head.

2. In combination with the die head of a wire drawing machine; a box or container separate and independent from the die, and

in which the die is held, having one open side; and means for movably mounting the same adjacent to said die head.

3. In combination with the die head of a wire drawing machine; a box or container movably mounted adjacent thereto and hav-' ing one slotted side, which slot in one of its positions is opposite to the slot in said die head.

4. In a device of the character described, the combination with the die head; of a box; means for niovably mounting the same in relation thereto. said box havingone open side and a slot through the opposite side,

'which slot in one of its positions is opposite the slot in said die head.

5. In a wiredrawing machine, the combination with a die head; of guiding means connected therewith adjacent to said die head; and a box movably mounted upon said guidino' means, said box having an open face adjacent to said die head and av slot in the opposite face.

6. In combination with the die head of a wire drawing machine; a box or container u'iovably mounted adjacent thereto with one open side that is closed by said die head and having a slot in the opposite side that opens through the top of the box.

7. In combination with the die head of a wire drawing machine; guide means secured adjacent thereto and substantially parallel with one face thereof; and a box or container slidably mounted upon said guide means. i

8. In combination with the die head of a wire drawing machine; a plurality of guides fixed relatively to said die head; a box or container movably mounted upon said guide means and having one open side which is closed by said die head. I I
