'To all wzovmct may concern.' 4

Be vit known that I, EMIL H. Murrina citizen of the United States, residing,- at Saratoga, in the county of Hardin and State of Texas, have inventedy certain new and useful Improvements in a `lVire-\Vintliiig Machine, of which the following` is a specification. I p p This invention relates to new and use-ful improvements in a wire win'dinp,` mach-ine.

One object ofthe` Ainvention is toprovide a wire winding machine specially designed for the purpose of winding wire on a frame or perforated pipe in theV process of manufacturinglwell screens.- Y y i Another object of the invention isA toA provide a machine of the characterdescribed whereby the screen wire may be wound on the perforated pipe, or screen frame, in the form of a helix, with its turnsspaced a uniform-` distance apart. Y

A. further feature of the invent-ion resides in the provision of a wire Winding' machine whereby spacing` lugs, ofv 'uniform height may be thrown out from thewire Vas it passes through` the machine, and saidj lugs, being' formed ofuniformWheight, need not be cut down to produce evenness in heighu and their' galvanized coatingthus need not be destroyed. 'A ,y

consists 1n an nna section of the screen wire, with the spacing;` y

lugs formed thereon; and,`

Figure 6 shows acrossA` section through adjacent turns of'the screen'wireas wound on the pipe. i v

Referring now morehparticularlyf to the drawings,-wherein like numerals ofreference-designate similar parts in each ofthe ggures, the numeral 1 designates the'body vlof the lathe, Thenumeralr 2 designates the lathe carriagewhich runs' upon the

tracks

3, 3 forming part of the .lathe body.m` The perforated pipe 1, formingv the screenframe, is mounted in the lathe, and is rotated fromthe lathe chuck (not shown) infthe well known manner. along, as winding` progresses. by means of the rotary screw shaft 5"whi`ch is rotated b v the lathe mechanism andwliichl is threaded through the split, tappedfbearing' carried by the carriage. VThe pipe 4'. issupported on the rollers i', 7. These rollers are mounted on the bearing` rods 8, 8', `whose re`- spective ends Vare anchored to the upper ends of the respectivepairs of toggle linkslt), 9. The `lower endsof theselinlrs of therespective pairs, have bearings on a'` common bearing' rod 1t), carried bythe'lathe carriage. The

rollers

7, 7, may be adjusted, andthe pipe d' thuselevated or lowered' through the adjusting screws 11, 11 whiclrare attached attheir' upper ends to sleeves 12,12 on'the rods 8 8, and have screw connections with tapped

'bearings

18, 13 carried by opposite sides of the lathe carriage. As the carriage moves along, thepipe 41 is rotated andthe screen-wire 11 isW'Ound, in a helix,` on said pipe. The wire passes through between the

guide rollers

15, 15 which aremounted in the frame 16'. These rollers are spaced apartv to allow space for the wire and they will" usually be tapered upwardly since the wire,` in `cross Asection` is usually lteystone in shape. The wire is held between the feed rollers by means of a U-shaped bridge 1.7, forming part of the frame-16, and disposed above the wire. The wire`v moves along in the grooves of the

guide rollers

18, 18, can ried'by the frame 16, being` held in said `grooves by the' pressure' roller 19' which presses against tlieupper'side of the wire'. The pressure" rollerisvertically adjustable 'so as to accommodatewires Aof differentsizes.

It isnec'essa'rythat the wire be wound-under tension' and theV pressure roller 19"imparts the tension required` Mounted onthe frame 16 there is ay die roller 20, and above it, the punchinpgvroller 21. Y These respective `rollers are clanipediu `on and rotate with thespindles 22`andf23, which in turn rotate" on: the" sleeves 243 and` 25, mounted,r respectively, ony the

bearing rods

26 and 27. The spindles `have'the inter-nal annular oil chambersff and 29,1Whichj`s`ur- The carriage is driven sov round the lsleevest 31116.25, and-from which lead the ports 30 and 31. Oil is admitted into the oil chambers through the respective ducts 32 and` 33, for lubricating the sleeve bearings. r1`his mechanism is suitably mounted inalframe consisting of the

side members

34 and 35, which in turn is secured to the frame 16. The dierollerhas .any annular groove 36 ot the same cross sectional contour as that lof the screen wire, and at its top thisA groove is widened on one side orming-anabrupt annularshoulder 3'? which is set baclr'l'rom' the main groove the exact distance the turns of the screen` wire are to be spaced apart. The punching roller ..3V carries a pluralityk of projecting radiating punches 3S whose points are V.aligned with the groove .36 Vso as to strikethe wire between its longitudinal center and its edge toward the shoulder 37 This alignment is maintained by the annular rib 39 o't' one spindle which runs in an annular groove 40 of the other spindle. Y. y

' As before stated the wire isk pulled through between the rollers bythe rotation ot' the pipef4, and the punches indent the top side of the wire and thereby throw o ut the spacer lugs 41, onone side. `The height ofthese lugsis determined by the annularshoulder 37 against whichthey abutV as lthrown out. This ,shoulder not onlyi insures the uniformity in height of the lugs, lout alsoA forms their crests with flat `faces 42vwhich form seats for the ylugs againstthe adjacent-turns of thel wire in winding.` as Villustrated in Figure 6` j f As the wire winds on the pipe 4, the lugs of the turn being wound are 'forced up ,closely againstthe preceding turn of wire by means ot a pressure lroller 43 which is rotatably mounted on `the lower end oil the spindle 44. This spindle depends from the anchor 45, which inV turn is secured to the t'ra-me 16. rlhis ilrame`16 is mounted to pivoton the vertical axis bvmeans o'lf the bearing'451I.v which is mountedon the vertical spindle" 46.1,carried 'byJ the lathe carjiiage 2. The frame 16 is also mounted to pivot on a horizontal axis lbyjmeans ot the horizontal bearing 47 which is 'formed integrally with the bearing 45 by .the web 48. A spindle 49 is fastened to thc frame 16 and has aV bearing ink said horizontal bearing 47. The outer end of the spindle 49 has a `for Yardly'extending rod 50, pivoted thereto which works through a. bearing 51 carried by the carriage 2. The outer end of this rod hasa head 52 and interposed between the head 52 and the bearing 51, and surroundingthe r0d'50 there is a coil pressure spring 53.' This springl` operates to hold the pressure roller 43 yieldingly vaga-inst the wire as wound on the pipe.

The spacer lugs hold the turns of wire Asuitably spaced apart on the pipe, .thus providing a screening surface.

The end of the frame 16, opposite its pivotal supportk on'its horizontal bearing 47, hasan open bearing 54, and an adjusting rod 55 is anchored to the' lathe carriage and stands up through said bearing 54 and its upper end i's provided with a head 56. There is .a slidable collar 57 which rests on the rame16 and through which the rod 55 slides'and a coil spring 56 surrounds said rod and is interposed between the headf and thecollar 57. This coil spring operates to hold the pressure roller yieldingly against the pipe.

, It is to be noted that the carriage heretotore designated by the numeral 2 has n. movable section 2, capable of adjustment relativegto the restrot the carriage. This section2ot the carriage carries the split bearing 6 through which the screw shaft 5 is threaded. l

The main body Vof the carriage 2 hasV aligned be'aringsf59, 59. through which the Stays 60, 60 slide. These stays are attached to the section 2. There is a. rotary internallythreaded sleeve 61,'which has a swiveling connect-ion with the main carriage 2` and this sleeve 61. is turnable` through the hand grips 62 carried'thereby. There` is c i an outwardlyrthreaded rodv63 fastened at oneY end tothecarriage section 2.',-and it is threaded through the sleeve 61.v Inasmuch as the frame 16 is carried by the main body of the carriage-9 this frame and the winding mechanism carried thereby, may be adjusted relative to the work by the adjustment of thecarriage sections, relative to each other, through the mechanism hereinbefore described, provided -for that purpose. j i It is to be furthernoted that the punching roller is adjustable relative to the die roller, 'sof that the strokej of` the punches against the wire can be casilyfcontrolled. This adjustment fean Abe accomplished by turning the bearing rod 27 which .is eccentric relativefto the' punching roller. This rod may bereadily turned through the collar G4 which is splined on said rod, as shown in Figure 4. This adjustment is also necessary to facilitate ythe threading of thewire through between these rollers in beginning the work or winding.

1t is also to be noted that there is a shim (l'ietween ther die, roller 2O and the opposing shoulder ofthe spindle Q2 on which it is mounted. By varying the thickness ol this shim, or thel number or' shims, the roller 2O can be laterally adjusted and the point of contact of the. punches 88relative to the edge of the wire, thus regulated.

That 1 claim is:

1. In afwirewinding machine, a die roller having a; peripheral grec-ve, .a punching roller spacedfron'i the die roller, projecting punches radi ating from thejpuuching roller,

and alignedfwith said groove, spindles on lll) retraso? which aid rollers are mounted, said spindles having internal annular oil chambers provided with inlet ducts, bearing sleeves on which the spindles are mounted, said sleeves having oil ports, hearing rods on which the sleeves are mounted, and a frame in which said rods are mounted` 2. In a Wire Winding machine, a die roller having a peripheral groove, a pun-ching roller spaced from the die roller, projecting punches radiating from the punching roller and aligned Withsaid groove, spindles on which said rollers are mounted, bearing rods on which .said spindles are mounted, a 'frame supporting said rods, one of said spindles having an annular groove andan annular rib carried by the other spindle and running in said annular groove.

3. In a wire Winding machine, mechanism including a die roller having a peripheral groove, a punching roller spaced from the die roller, projecting punches radiating from the punching roller and aligned With said groove, means permitting the adjustment of one of said rollers on its hearing to vary the position of said punches laterally with respect to said groove, means for adjusting one of said 'rollers toward and from the other roller, a carriage formed of two sections, for driving the same, said mechanism being mount-ed on the other section, and means for adjusting .said sections toward and from each other.

In testimony whereof I have .signed my name to this speciiication.
