In the makingof wellscreens by forming a helix of wire which is supported upon a base such as a perforated pipe or a frame made of bars, itis often necessary that the wire be 'spaced;'very close together and in all cases' the spacin shall bevmade with extreme unilt is highly desirable to use a wire fo'rmity. g of the general form of Figure 9, in which the greatest strength ofthe wire is provided in a radial direction to oppose the'pressure of the V fluid upon the screen and it is of course necessary that this wire be-placed upon a frame in its correct upright'position. In my ma- Specification of Letters Patent.

relates particularly to mafrom such spacing means.

, Patented May 15, 1906.

' chine I use the surface of-the previously Wound turns of wire asa screw for advancing the guiding frame along the support as the winding progresses, and the guide for spacing the wire in the preferred form of the'machine made to engage several of these turns of wire, so as to have the advance motion correspond with the average surfaces of the pre viously wound turns, avoiding variations due '6 5 to irregularities in the shape of the Wire.

For this purpose a principal part of my m vention is the form of the guide which engag'esthe previously wound'helix, to be hereinafter described. The devices herein shown are designed to be used upoifnany such machine as an ordinarylathewhere there is provision for rotatin the screen frame, and in the illustrations have shown a pipe uponv which to wind the screen; but it will be understood of course that the same devices for Winding may be used with a collapsible mandrel or upon any other form of supportingframe adapted to be carried-by and revolved by the lathe.

In the machine as shown in Figures '1 and Z'especially, it will'be seen that I have provided a rocking frame 10 which is provided with a clamp 11 by means of which it can be secured to the tool rest of an ordinary lathe, 8

the clamp being pivoted by the bolt 12 to the frame 10. It will be apparent that theframe .10 may .be fed: along entirely by the spacing guide heretofore referred to, or,'- if .desired, bythe feed'-m'echanism" of the to'ol'go rest acting in conjunction with the spacing means to take the main strain of the feed The entire'device may therefore be. slid laterally or parallel -wi th.the axis of 'theframe upon which the 5 wire A is being wound. This wire A, enters the rear end of the machinethrough a tension block 13,- and then passes between a series of tension rollers 14,15, of which the latter roll may be pressed down to regulate the '1 0o tension by means of a screw. The wire passes through a set-of'adjusting rolls 16, 17, which are geared together by the gear. 1-7 a in order to move in unison, and from this point the wire passes through the center of a hol- I0 5 low guide 'arm 21set in the slotted block 18 which is pivoted for vertical movement by means of pointed screws 19 so that the frame .21 may rise and fall tofollow any radial un- The front jaw I re evenness in the screen frame, of the guide arm 21 is prov ded with a lower grooved-roller 22 made to'fit the bottom portionof the wire such as shown in Figure 9,

and with an upper roll 23 to engage the top portion. The arm 21 is maintained in the block 18 against rotation therein by means of a clamping screw 20, and it will be observed that by loosening this screw the rod 21 may be laterally rotated in its support or twisted as desired and thereby the wire passing through the .rolls 22 and 23 may be tilted in I0 order to allow for any unevenness in its shape and force it to come in contact with the revolving pipe or frame in a vertical position.

' The forward end of the frame or carriage is provided with an adjustable extension I5 arm 24 attached thereto by bolts in slots as shown in Figure 1, and in the front end 25 is provided an upright strut 24 which carries a socket 26 for reciprocation of the stem 27 of the guide roller 29. Shaft 27 is kept pressed 2o downward by the coil spring 28, and as is shown. more clearly in Figure 3, it has a laterally projecting arbor 27 which forms the journal. of the guide roller 29. The guide roller is formed with a series of flexible steel 25 disks'30 which are loose upon the hub 29 and compressed against one another by the rings 31. These rings 31 are given a rounded contour as shown'in Figure 3 so that they enga e the surfaces of the flexible steel disks only 30' at one point, as 32 in said figure. The whole set of disks 31 and rings 30 are clamped to' the mean position. of the surfaces on the wound wire and therefore the guide does not 4 5 vary in movement by any unevenness in any single turn of wire. This function I find to be of great importance in winding screen's so that the continuous slits between the coils of the helix maybe very regularand therefore the screen will stop the'same size of sand at all parts of its length. It will be understood of course that when the space between the wires is to be changed, a different set ofthe guide disks 30 may readily be applied .to the roller, or several thinner disks may be built up and may engage both'of the contiguous wires without interference with each other.

As the winding of the screen proceedsit will be seen of course that the guide roller will advance the frame by the reaction upon the aw 24 carrying with it the guide arm 21 and the whole carriage.

The above described machine is especially adapted to the use of wire having a smooth 6; side. But itwill be understood that it can beused with any wire. In Figures 5, to 8 are shown details of a modified machine in which the slight variations are designed to accommodate the improved wire f0r, well screens, which has laterally projecting spacing spurs formed thereon, whereby the wire is spaced properly by bringing the spurs in contact with the next preceding helix of wire. In this instance also I have shown a diflerent means for mountin the frame. From Figures 5 and 6 especia ly it will be seen that the frame 34 engages a uide bar by means of a set of wheels 34 at t e rear end, and the for.- wardly projecting end of'the frame has a jaw 35 extending over the top of the screen which is being wound and also has a downwardly looped removable jaw 36 which is provided with rollers 36* to en agethe screen frame and the already woun screen upon the two respective sides. The pivoted jaw 36 is pro- 8 5 vided with a link 37 and bar 37 a to engage the top of the jaw 35 and held thereon by a nut 38' and regulated by pressure of a coil spring, as will be well understood from the figures.

J ournaled in the forwardly projecting jaw 0 35 I have provided a shaft having two steadying wheels 39 and 40, the former one of which engages the pipe or frame on which the screen is being wound and the latter engaging the already wound screen as will be observed from 9 5 Figures 5 and 6. The wire A is pressed down firmly upon the screen by means of a roll 41 mounted in a spring arm 42, and passes through a slit in the bifurcated plate 44 attached to'the top of the frame 34. A suppleroe mentary set of guiding rollers 43. and 45 may be provided inthe forward end of the frame 34 and they are preferably mounted upon e transverse shaft 43, one of said rollers resting upon the pipe or frame and the other'r o5 upon the previously wound screen. Be-

. tween them is mounted a pivoted guide block 46 which engages the last turn of the helix of wire already wound as shownin Figure 6, and serves to push the entire carriage no forward as the winding proceeds. The shaft 43 is supported'at its ends in bearing blocks 43*, and is held in position by means of a cotter'key through each end as shown in Figure '5. The blocks 43 are tapped into the sides II 5 of the frame 34, and bear with their inner ends against the outer faces of the rollers 43 and 45, thus holdin the rollers and block 46 inposition and allowing them to be,ad-

justed to -aline properly Wlth the wire prer20 viously wound.

The wire, which in this instance has'a section shown at Figure 9 and is to be provided withlaterally projecting spacing spurs a as 1 shown therein, first enters the rollers 47 and after passing between the tension rollers 48 passes over a slotted roller 49 and under a smooth roller 50 which is provided at points along its surface with sharp teeth'5l which serve to compress the top of the wire and 1 0 of course-engage the sur ace of the previously.

cause the spreading of the .same to form the laterally'projecting spurs a, as .shown more clearly in Figures 8 and '9. a The lower roll 419 is providedwith' lateral slots 54. to accommodate the projecting spurs. geared together at the rear side by the gears 52 and 53 so that they revolve together. In

order to provide for a slight adjustment of the'distance between the rolls 49 and 50 the latter is mounted upon an eccentric stud as wound turn of the helix. and properly space the wires apart so that the screen having been wound it is fixedly spaced without the necessity of soldering it to its frame or pro viding other means for maintaining the correct spacing.

It will be understood that whendesired, the guide block 46 and the bifurcated plate 44of this alternate form of the machine may be omitted. and the guide roller of the machine of Figure 1 .may be used to advance the carriage along the screen, by simply altering the distance of thedisksfrom'the support so that they engage the wire above the projecting spurs a. In this case again, the form of the resilient guide roll is-of partic'ular importance since it will be observedthat punching the spurs a may-often 'make the wire of variable width on top, and since all the disks do not engage the spurs uponthe wire at the same time, some one of the disks 30 will be in constant engagement with some one of the s urs from the wire on one side and therefore t e average or mean position of the previously wound turns of the helix of wire would govern the carriage of the machine along the screen. The guide roller is ap licable to wire of any form, and wire either p ain or having spurs thereon, and in all cases the flexibility of the engaging disks and the fact that there are a number of them, enables the machine to be governed by the mean position of the previously wound turns of the helix and to advance according to the average progress of the Wires along the screen and not to be varied by unevenness in any one articular turn of the wire. Various other a vantages of these devices will readily occur to those familiar with the art.
