WIRE-DRAWING MACHINE.

Specification of Letters Patent.

Application filed May 29, 1913.

Patented May 5, 1914. Serial No. 770,748.

ellicient, facile aml comparatively rapid manner. v

The invention consists essentially in combining in a single machine, a succession of gage-reducing devices by means of which the gage ot' the wire may be successively reduced as it is drawn out, and in certain novel forms and comlnations and arrangements ol parts for actuating' the instrumentalities,

` and adjusting the parts ot the machine in the perlormance of its functions.

in the accon'ipanying drawings I have illustrated one complete example of the physical embodiment of the machine constructed according to the liest mode I have so i'ar devised tor the practical application of the principles ot' the invention.

i Figure l a side elevation of a machine embmlying` the invention. Fig. 2 is an elevation ot' the machine from the side opposite Fig. 1. Fig. 3 is a top plan view. Fig. -l -is a transverse, vertical section on line 4 1 Fig. 5 is a vertical. section on line 5---5 ["ig. Fig. G is a fragmentary sectional view showing in detail elevation a guide roll Vtor the wire as it wound upon a drum. and means for adjusting the. roll with relation tothe drum. Fig. 7 is a detail perspecl ive vien1 of a tool employed in starting to wind the end Ot' thewire on the drums prclauatory to drawing the wire` the employment of the, tool being only temporary 't'or the purpose ot' starting the operation of drawing or reducing` the wire.

In the preferred embodiment of the invention l employ a plurality ot' winding drumsarranged as in Figs. l and 3 aml designated 1, Q, and 3. These drums are `supported on their respective shafts at, 5, 6, which are journaled in a lrame 7 projecting upright from the table The table 8 is a suitable altitudc from the floor and is supported upon corner legs 9, thc whole preferably being metal. The drum shafts t, 5, 6, are driven li lg. 2.

.hold the p late in either upper from the countershaftlO, which extends longitudinally of the machine and is journaled in bearings .11, 11. The motion of the countershaft 10 is t'ansmitted to the drum shafts by means of duplicate pairs of gears 12, 13, the former fixed on thecountershaft and the latter tight on the drum shafts. The counter shaft or driven shaft 10 is re-y volved from the driving shaft 141 through the medium of the pair of bevel gears l5 and 16, and the driving shaft has motion transmitted thereto by belt 17 and tight pulley 18, an idle pulley 19 being employed as usual.

In conjunction with the series of winding drains I employ a series of gage- plates 20, 91, 22, 23, each oi' which is provided with a set of perforations (see Fig. 4) increasing from a minimum as 24, to a maximum opening- 25. These plates are identical in construction, except that the gage perforations may be graduated in size, and the description of 011e plate and its accessories will be sufficient for all of the series. The plates are cach provided with a handle 26 and are adjustably supported in a slotted bracket 2T,

attached as by bolts 28 to the frame 7. The

plate is held between an upper and lower block 2t) and 30 respectively, against which the screw bars 31, 32, have av bearing. These barsl are threaded into bosses on the bracket and may be turned by handles 33, 3-1, to

or lower adjusted position.

Each ot' the winding drains is provided with side tianges 35 between which a guide roller 3(3.may rotate.' This Aroller is supported in a frame A37 in bearings 3S, andv the forked frame may be moved vertically lo means ot' the screw bar 3f) rotatably held in the bracket l0. which is securely attached to the trame i'. The bracket is ilormed with a iianged rib ll about which the slotted portion 42 ot' the frame BT tits. and in this manner the movement oi the trame 37 is guided as it slides vertically. (Figs. 3, G.)

Preparatory to being wound upon the first drum of the series? the wire `to be drawn is sharpem-d i. e. it is reduced in diameter sufficient to permit its being inserted through thc gage peiltoration selected in the first gage plate 20. In a machine as depicted in the drawings, approximately the first twenty or thirty feet are thus reduced. This sharpening is accomplished bymeans of the grooved rollers 4.8. -t-; (see Fig. 4) lo` .number 67. This receiving drum is cated at the front of the machine and supported by their shafts 45, 46v in the frame or uprights 47 fixed to the table top 8. ,The shaftsv 45, 46 are geared together by the Wheels 48, 49 and are provided with a series of complementary grooves 50 which gradually increase in diameter from left to right Fig. 4. Because of the geared connection the grooved rollers 43, 44 of course move in different directions, and they are revolved through the medium of the shaft 46 of the lower roll 44. This shaft is driven or continuously revolved by a crank arm 51 on its end Which is connected by pitinan 52 with the bell crank lever 53 on the transverse rock shaft 54. This rock shaft is supported under the table in bearings 55 and is rocked by a longitudinally reciprocating rod or bar 56 connected to the rock shaft by one arm of the bell crank lever as 53. The reciprocating bar orV rod 56 extends toward the rear of the machine and its actuating mechanism is best seen in Fig. 5. A second transverse rock shaft 57 is supported under the table in bearings 58 and the reciprocating rod is connected to this shaft by lever arm 59, While a second lever arm fixed to the rock shaft 57 as 6() connects the pitman 61 with the crank 62 of the shaft 63 which is supported in bearingbrackets 64 above the table top 8.

This crank shaft receives motion from countershaft 10 through the medium of the gears 65, 66 (Fig. 3).

At the rear of the machine a vertically disposed receiving drum is designated by ihe esigned to receive the wire after it has been drawn to the required thickness, andit is supported as clearly seen in Fig. 5 from the ta le 8 on bracket 68 in Whichthe trunnion or shaft 69 is journaled and upon which the drum revolves as a center. Upon its closed bottom -a beveled wheel 70 is provided and the bevel pinion 71 meshes with this wheel to revolve the receiving drum. rThe bevel pinion 71 is fixed on the end of the transverse shaft 72 Which passes through the frame 7 and is journaled 'in bearings .78. The shaft 72 is driven from the drive shaft 14 just above it through the tWo meshing gear Wheels 74 and 7 5, the former on the drive shaft 14 and the latter on the driven shaft 72. The driving shaft 14 is also provided with a balance or ily wheel 7G 'between the bearing 73 and gear wheel 74, to steady and render regular the movement of the shafts..

A belt shifter 77 (Fig. 55) is adapted to shift the belt 17 from' the idle pulley to the `drive pulley and vice versa iii starting or stopping the machine, and this shifter may be actuated from any one of various positionsl 0f the machine by a series of handlesv 78 attached to the oscillatable bar 79 which extends approximately the length of the machine and may rock in its bearings 80 atgrooves tached to the frame 7. The rock bar and shifter are pivoted together at 81 by means of a slotted connection as best shown in Fig. 5.

From the above description taken in con` nection with the drawings it Will be noted that when the belt 17 has been shifted to the drive pulley and a suitable motor (not shown) is iu motion the motion Will be transmitted to the driving shaft and through the driving shaft to all themoving parts as has been described. In the operation of drawing wire I employ a tool 82 (Fig. 7) as a convenient means for starting the wire about the Winding drums. This tool is attached to one end of the wire to be drawn by means of the chain 83 and pincers 84 (Fig. 1) and the tool may be attached vto the drum, and to each drum successively as will be explained, by iitting the tool in one of a series of radial recesses or notches S5 formed in the flange of each of the winding diums 1, 2, 3.

its before stated the Wire to be drawn is first reduced-to a minimumgage for 'a dis tance of twenty or thirty feet at its end depending upon the number of Winding drums iii use on the machine and the accompanying gage plates. This reduction of the ga e as a preliminary is accomplished on t e gi'ooved rollers lby utilizing successively the beginning with the large one and finishing With the smallest. The Wire end is fed through the grooves, and Withdrawn successively until the` minimum gage is reached, and the Wire end is now ready to be inserted through the lfirst gage plate 20. wire end that has been thus may now be threaded through the maximum opening 25 in first age-plate 20. After the end has been passe the pincers 84 are wire (Fig. 1) and the tool 82 is located in place on the first Winding drum 1 as described. The power is now applied to the machine and the Winding drums revolved. After several turns have been Wound about the first drum, the toolv 82 is detached and the wire is wrapped about the drum 1 so that enough wire will be left at the end to permit successive threading through plates 21,

22, 23 and winding about the drums 2, 3,"

The sharpened hole or opening in the descending scale in plate 28 is Wound about the receiving drum 67. The machine is now ready to draw the wire, the driving power being applied, and

101s` through the first plate, 4 fastened to the end of the' the several operating devices are set in motion. The wire is drawn through successively smaller gage openings in the age Plates and is thus reduced to the gage o the ast 'gage opening inv the serles through which it brought own to proper position to guide the wire as itpasses aroun the successive drums and they prevent the'f" turns of the wire `from becomlng loose or tangled on the drums over which they-are passing. l

By the adjusting means f Fig. 4 it will be seen that the gage plates maybe adjusted vertically and laterally to bring any one of the set of openin s into .line so that the wire nay pass throng the machine on a straight me. 1 Y

The entire machinerytf while in o eration runs smoothly and re ily wheel performing lts function of steadying and regulatingthe momentum, and the separate devices are actuated continuously and simultaneously, the wire after being acted on by the several devices, finally being wound upon the receiving drum 67.. The belt may be thrown off at any time by any asses. The guide rollers 36 areguiiarly, the ba anceA or.
