To all whom i! may concern.'

Be it known that I, Fimo I. GETTY, e citizen of the United States, residing et Jennings, in the parish of Celciisieu und Stute of Louisiane, have invented certain new end useful Improvements in Machines for Menufncturing bcreenings for Well- `ubes, of which the following is n s ieciiicetion.

`My invention relates to cert-nin new und useful improvements in machines for menufncturing screening for well tubes und its object is to produce n device off this class which shell have certain advantages which will appear more fully and et large in the course of .this specificntion.

To this ond, my invention consists in the Anovel-features which nre shown in the eccompanying drawings es embodied in my preferred form of construction..

In the aforesaid drnwingsF1gure 1 1s en elevation of iny improved device, showing the saine in use; Fig. 2 is a face view of the bracket which holds the wire-guide in en upright position; Fig. 3 is a section in the line 3--3 of Fig. 4, through the wire-guide; Fig. 4 is n section in the line 44 of Fig. 1, looking in the direction, of the arrow; Fig. 'is e top plan of the screen-forming mechanism; Fig. 6 is e front view of the seme; Fig. 7 is n horizontal Section in the line 7 7* of Fig. 4; Fig, 8 is e rear elevation of the mechanism; Fig. 9 isn section in the line 9-9 of Fig. 5;

10 is a. )erspcctivc view of the'suppi'irting frame; ig. 11 is a section in the line 11--11 of Fig, l; looking in the direction of the arrow; Fig. '12 is en elevation of the forming rolls, looking from the left in Fig. 5 Fig. 13 isn horizontal section in the line 13-,13 of Fig. 12; und Fig. 14 is a perspective view of the shifting shoe.

The type of screen which iny improved device isdesigned to forni is that wherein n wire having suitably-spaced lugs is wound around nl perforated pipe. ln practice, n long length of pipeis provided with perform tions of the proper size and is wound with wire from end to end. The pi e thus prepared may be joined by suiteb e couplings, so es to produce any desired length.

Referring now to the drawings, A, indiestes the pipe which is used, the sinne having n plurality of perforetions, a, and being ron tntnbly mounted in n. inthe, B, of the ordineryiorm. Thilo I prefer to use .an ordi- ,nary machine lathe, it will -be obvious that any device by which the pipe een he symmetricall and rotntebly journnled will'opersite equa ly es well. ln the use of my irnproved device, u freine, C, is mounted. di rectly upon the pipe itself, the seid freine being yieldingly pressed toward the left, es viewed -in Fig. 1, by ineens of n. weight, C,

connected with the freine by e cord, c, run.

ningr over pulleys, c2. The frame C, has e rearwardlyprojeating nrni, C2, which rests upon s rod, b, secured to the inthe-bed, seid rod operating to-limit the backward rotation of the freine as the .pipe-is-roteted. In other words, the rod by engaging with the erin, C2, preyents the frame from rotating, und muses it tb remain stationery on the rotating pi e, although it permits it to slide longitudinally on the pipe ngninst the the weight, C1. y

The frame, C, it will be seen, is roughly U- shrtped in form (see Fig. 10), und it is adapted to receive the pipe, A. At the forward end of the freine are three upwerdly-projecting osts, c, forming between `them two notcfies, in which rest the forward ends of two straps, I), D1, thesaid forward ends being held down by ineens of screws, d, pnssed through e plete, d1, secured tothe upper endsof the post, c1. Lock-nuts, (Z2, are provided on the screws or bolts, d. The rear ends of the straps., D, D4, are passed through holes, c2, (Figs. 7, 8 and 10), in the Vupwerdly-ex tending rear portion of the frnme,C. The

'rear ends of these straps are likewise held down by means of set-screws; or bolts, d8. The stfrep, D, has edjustnbly securedto it-ial guiding shoe, E, n bolt, e, serving to effect the connection, while the stra D1, cerriesfe. vshifting shoe, El, connected tierewlth by a.

bolt, ell Both these shoes beni' against the upper surface ofthe pipe end together they form the bearing which prevents downward movement of the freine with respect to the pipe. The shifting shoe, El, 'has other purposes which will presently be explained; but the shoe, E serves .only to furnish a large bearing conforming substantially to the sur- ,fece of the pipe. ends of the straps cnn be ndjusted and the shoes cen also be adjusted on the straps, so that any desired pressure can be obtained between the shoes end -the pipe. When it is desired to operate on pipes of different diameters, theshoes can readily be removed` and otlierssubstituted which will conform 'to its surface. YIn ol'der to complete the centering of the frnmef pressure exerted by It will be seen lthat thef on lthe pipe, two other f vfrollers,

bearinglates, c4, secured thereto vThese as will be seen from Fig. 4, bear on thegfront side ofthe pipe above its center and tend to prevent backward, and, to a cerplurality of lugs, h2.

tainl extent, downward movement of thev frame on the pipe. lThe third bearing of the `frame on the pi e isy provided by two rollers,

G, (Figs. 4 an 7) mounted on a shaft, g,

` carried on the ends of two triangular plates,

G1, pivoted at their upper ends to the opposite sides of the rear leg of the frame and provided with a lock-bolt, f/l, running in slots, g2, by which they can be locked in any desired an lar iosition. As a further means for iXing t 1e position of the rollers, G, the plates, Gr, are provided on their lower edges withnotches, g3, (Fig. 4) which are adapted to Abe engagedby the laterally-projecting ends g, on a locking plate, G2, (Fig. 8) adjustably secured to the rear face of the rear le .of theframe, (l. It will be seen that the rol ers, G, will cooperate withvthe rollers,

` F, and the shoes, E, E1, to center a' pipe, of

any desired size, within the frame and will still leave the pipe free to rotate within the frame while the frame is free to'slide longitudinally on the pipe. When a pipe of srraller diameter than the one shown 1n the drawings is used, the rollers, G, are swung up sothat the pipe may be held at the propel height with res eet to certain forming rolls hereafter deseri ed, in order that the wire may be properly ferito the pipe from said rolls.

vThe form of wire for which the machine herein illustrated is particularly designed, is that illustrated in my pending ap lication for patent on 'strainers for wells file December l, 1904, and allotted Serial Number 235,124.

0f the edges, 7L, of the head of the T` being plain, and the opposite edge, h1, having a The head of the T, in practice, lies parallel to the axis of the pipe and the central web, h3, thereof lies at right It will. be obvious that cerned could. be used with. wire of any desired cross-section; but since, this is my .preferred wire, I illustrate a machine for operating upon it. In the use of the machine, the

wire is furnished in the-form in which it is.

wound on the ipe, except that the op osite edges of the T- iead are not fully forme until it reaches the machine. My machine, there- Tore, comprises the devices for guiding the wire, forming the flat surface and the lugged surface on the .T-head', and windin the Wire 'upon the'ppel. These devices A' now be `with the greatest ease.

This wire indicated in the draw-A ings by, H, is T-shaped in cross-section, one

scacco described, beginning at the front of the machinev where the first guiding device which the Wire strikes is situated.

I, indicates a vertical vroller which bears against one edge of the wire as it comes from the reel, holding the same'between two vertical guide rollers, J, mounted upon a post,.j.

After the Wire passes by the rollers, J, it passes between two rollersfl, L, the said rollers having horizontal grooves, lr, Z, rc-

i of Wire bear against the ilat surface of the next turn, and consequently the height of the lugs determines the mesh of the screen.

The liei ht of the lugs is determined exactly by the e th of the notches,'l2, in the groove, l. In sel ing screening of this sort, it is necessary that its mesh shall correspond approxi-A mately to the meshes of ordinary wire gauze, and by using a set of interchangeablerollers, a single machine can. be made to turnout wire suitable for forming screens with mesh corresponding to any of the standard gauze 'meshes In order to make the change from one set of rollers to another a comparatively easy matter, I havey adopted the bearing herein shown which is particularly simple and in which the rollers, K, L, can be changed It will be seen that said rollers, K, L, are mounted on shafts, K1, L1, bein held in lace between shoulders, K2, L-, andg nuts, Ig, L3.' Bearing blocks., K", L, are provided for the shafts, K1, L, respectively. These blocks are vheld in ver- When tical guides formed between upwardly-projecting ribs er flanges, c5, on the frame, C, and a plate, C, being laterally-adjustable by means of screws or bolts, 7c3, Z3, (Fig. 5) and ivertically-adjustable by means fof screws or bolts, 7c, Z4, (Fig. 9). These blocks, it will be seen, are provided'with slightly Aflaring ad jacent faces, (Fig. 5) in which faces are semicylindrical vertical grooves adapted to receive the shafts, K1, L1. The blocks are rovided with central, flat-bottomed notc es, which afford space for the collars on the shait, the grooved rollers and the lock-nuts for the same. The shoulders on the shafts lio rest against the Hat bottoms of the notches l in the bearing blocks and revent longitudi-.-

nal movement of the ro ers with respect thereto. The device is assembled. by placing the rollers in the roper relations totheir respective bearing locksand 'then placing the blocks in the guides.'V The parts are then firmly locked in positionagainst any ordinary strainwhic i couldoccurin practice.

The rollers can not be moved forward from the bearing blocks, because to-move forward they must first swing together, and such movement is obviously impossible, because the s ace between the hearing blocks is too.

wirein place. This guide is su ported by movement by means of a pin, m2, running between flanges, n, on a guide, N, (Figs. 2 `and 5). The guide, M, it will be seen, keeps the wire. in its roper position', and fits it to the pipe with t ie T-head horizontal.-

The only motive power which is used in operating my device is that applied directlyr to the'pipe itself. One end of the wire is assed through the various guides and the orming rollsand secured to the pipe. The

I realize that considerable variation is pos sible inthe details of this construction, withlBackward movement out departing from the spirit of my invention, and I do not intend to limit myself to the s eciic form herein shown and described.

I c aim as new and desire to secure by Letters Patent 1. In a machine for making wire wrapped strainers, the combination with means for rotating a central core upon which the wire is to be wound, of a forming device adapted to operate on the wire as it passes to the core, said forming device being operated by the pull of thewire imparted by the winding mechanism, and a shifting shoe connected to the forming device and arranged in such relation to the pass of the forming device as to engage the advance edge of the wire wrapped on the core'whereby the forming device is moved forward as the winding operation progresses.

2. In a machine for making wire wrapped strainers, the combination with means for rotating a central core upon which the wire is to be wound, of a pair of rolls through which the wire is drawn by the pull of the winding means in its passage to the core, and a shifting shoe connected` to the rolls and arranged in such relation to the pass between the rolls as to engage the advance edge of the wire wrapped on'tlie core, whereby -thc rolls are moved forward as the winding operation progresses.

3. In a machine for making wire wrapped strainers, the combination with means for ro# tating a central core upon which the wire is to be wound, of a lug-forming device comprising a pair of rolls, one of which is provided with depressions into which the metal of the wire is compressed to form lugs, said lug-forming rolls being operated by the pull of the wire imparted by the' winding mechanism, and a` shifting shoe connected to the forming device and arranged in such relation to the pass of the forming device as to engage the advance edge of the wire wrapped on the core, whereby the forming device 'is moved fori` ward as the winding o eration progresses.

In witness whereof have signed the abovel a plication for Letters Patent at Jennings, in tlie. parish of (la casieu and State of Louisiana, this 21st day of March, A. D. 1905.
