To all whom it may concern: I

Be it known that 1-, HENRY ERNEST PARRY TAYLOR, a citizen of the United States, residing at Seymour, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Wire- Drawing Machines,' of which the following is a specification.

This invention relates to wire drawing machines and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

Wire drawing machines as heretofore used have been of relatively complicated construction, which complications have been detrimental to the character of work performed by the machines and have been a source of much expense for installation and maintenance. v

Among the objectionable features found in such machines may be mentioned, first: complicated lever mechanisms for operating clutch members; second: unsatisfactory means for transmitting movement to the movable parts of the machines, whichimeans lack suitable and simple means for-holdin the wire reel in position; and third: insu ficient provision for the proper adjustment properly presented to the wire block.

The object of this invention is to provide a machine cf the character indicated which is of durable construction and simple arrangement of parts and which is adapted to be used for drawing wire of comparatively minute transyerse-dimension's up to rods of five-eighths of an inch in diameter or thereabout." p K My machine consists primarily of a ro tating shaft from which a wire block is suspended and a simple and durable clutch mechanism for transmitting movement to the said'shaft; 'An effective means is provided for transmitting movement toa worm shaft through which motion is initially transmitted to the 'movable parts of the machine. A wire reel of special construction 7 is provided. A 'shiftable plate is mounted upon the bed-plate of the machine and supports the wire reel above mentioned and a die holder in a manner'as will be herein after explained.

I, which ismounted upon the wire may be by horizontal pul The accompanying drawings illustrate my 5 improved invention, in which similar reference characters indicate like parts.

Figure 1 1s a front elevation of the machine. Fig. 2 is a side elevation of the maother. Fig. 4 is a horizontal sectional View of the machine taken on the line t4 of Fig. 2. Fig. 5 is a horizontal sectional view taken on the line 5-5 of hi 2. Fig. 6 is a horizontal sectional view 0 a portionof a wire block used upon the machine. Fig. 7'

is a vertical sectional View of a wire clamping device mounted upon the said wire block, and Fig. 8 is a vertical sectional view of a shi ftable standard mounted upon the machine'and carrying a wire reel and a die holder. j I

' The machine is provided with a bed-plate base 2. The standard '3 is fixedto the bed-plate 1 and the horizontally disposed shaft 4 is journaled for rotation in the upper portion of the standard '3. The power pulleys 5, 5, are attached to the opposite ends of the shaft 4: and the worm 6.1s. attached to the intermediate portion of theshaft 4 and is housed within the dome 7 located at the upper end of the standard 3. y The provision of a pulley on either end of the shaft 4 is particularly designed to increase the steadiness of operation of the machine. As drive belts runnin over ulleys will generally exert a partial horizontal pull upon the machine; it wil be evident that .by securing a drive pulley 5 to each end of shaft 4, swinging movement of the shaft in its bearin s which would be caused l on one end of the shaft, will. be prevented b horizontal pull in the same direction on t e'other end. Further it will be evident that when strain is exerted upon shaft 11, and transmitted through worm wheel 9, to oneside of vworm 6, said strain will cause swinging movement of shaft 4, and it will be evident that this swinging movement will be prevented by the double pulley arrangement. It will there fore be seen that the double pulley arrangeloo 1 rotates with the same.

ment will equalize or balance the strain upon the machine in transmlssion of power to overcome the strain upon shaft 11.

The sleeve 8 is journaled for rotation in the upper portion of the standard 3 and the worm wheel 9 is fixed to said sleeve. Said wheel 9 is housed within the casing 10 which communicates with the dome 7 and is also supported at the upper end of the standard 3. The wheel 9 meshes with the worm 6.

The shaft 11 is journaled in the sleeve 8 the trunnions 18 and is fixed to a shaft 20- which in turn is journaled in the standard 3. The arm 21 is fixed to the shaft 20 and is rovided with an adjustable weight22. The link 23 is pivotally connected at its upper end to the arm 21 and is pivotally connected at its lower end to the lever 24 which in turn is journaled to the side of the standard 3.

' The wire block 25 is suspended at the lower one end a die receivin end of the shaft 11. Said block is sub stantially conical in configuration and has in its side a recess 26, in which a wire clamping device 27 is pivotally mounted. The said wire clamping device is provided with the movable jaws 28 between which the end of the wire about to be drawn is confined.

The plate 29 is mounted upon the bedplate, 1 and has at its opposite sides elongated perforations 30 through which the bolts 31 pass and secure the said plate to the bed-plate. The plate 29 is rovided at its outer edge with a depending ug 32 which is provided with a set-screw 33 adapted to operate against the edge of the bed-plate 1 and which is adapted, when turned, to move the plate 29 to or from the wire block 25. The plate 29 is provided upon its upper side with the guides 34 which receive the block '35. The yoke 36 is pivotall mounted upon the block 35 and is adapte to swing horizontally.

The die I older 37 is pivoted in said yoke and is adapted to swin vertically. The block 35 may be adjuste longitudinally in the guides and the die holder 37 has at socket 38 in which is located a detachab e die 39. The die holder 37 is channeled out or troughed throu hout its entire length in a, plane occupie by the opening in the die 39, so as not to interfere with the feeding of the wire to the said die. The die holder 37 is provided at its end opposite to that to which the die is applied with a downwardly inclined shank 40 upon which is adjustably mounted a counterbalance weight 41. During the rotation of the wire block the die holder tends to move vertically along the face of the wire block. This tendency varies at different parts of the operation and theadjustable weight is provided to maintain the die-holder in correct position under difierent strains.

The standard 42 is fixed at its lower end to the guides 34 and is shiftable with the plate 29;. consequently the said standard may move toward and from the wire block 25. The block 35 and its attachments may be shifted laterally with relation to the said wire block. These/adjustments are desirable in drawing wire of different diameters. The reel 43 is mounted upon the standard 42 and is adapted to be passed through a coil of wire indicated by the dotted lines 44 in Fig. 1. The said reel is provided at its ends with the plates 45 which'- are provided at their sides remote from the wire block 25 with the jo'urnaled friction rollers 46 which also. pass transversely through the wire, roll and tend to reduce the friction as the wire is unwound from the said roll.

The operation of my machine is as follows: The shaft 4 is rotated by means of belts (not shown) which pass around the pulley wheels 5--5 Inasmuch as the shaft 4 carries the worm 6 which is in mesh with the worm wheel 9 and the ower is applied simultaneously to both end of the shaft 4 the tendency of the said shaft to have swinging movement is materially reduced or ensiderable degree the wear and friction of the shaft in its bearings, and preventing wear and friction upon the worm 6 and worm wheel 9. As the worm wheel 9 is rotated as above described, it carries with it the sleeve 8 and the clutch member 13.

When it is desired to rotate the shaft 11 thetweenthe clamping jaws 28 of the ivoted block 27. Therefore, as the saidb ock 27 is carried around with the block 25 the wire is drawn from the reel 43 through the die 39 and is wound upon the wire block 25. At the end of the o eration of winding the wire upon the bloc 25, and when the end of the wire 44 passes through the die tirely avoided, thereby reducing to a con- As the last said simple and durable construction is provided for drawing wire and that the parts are so arranged as to reduce friction and incidental wear and tear to a minimum and the parts may be readily adjusted relatively for drawing wire of different transverse dimensions. Having described my invention, what I claim as new and desire to secure by Letters Patent i's a T 1. In a machine of the character described,
