LINE oonrnon.

' Application filed November 2, 1926. Serial No. 145,742.

invention relates to a line control adapted to be associated with the rig of an oil or other well whereby injury and wear to the cable or line used inconnection therewith may effeetivelybe obviated, said invention being more particularly a continuation in part of the device or apparatus disclosed in my co-pendingapplication for a line spooler, Ser. No. 732,889, filed August 9, m 1924. v

Certain devices or apparatuses known as home made line controls, have been in public use for years, in oil well practice for steadying the movement of the line or cable as it is" wound or unwound from the usual drum associated with the rig, but these de vices have proven unsatisfactory. Certain other devices have also been proposed, but these have also been proven' unsatisfactory for the 'reason that they soon wear out and throw steel, chippedfrom the moving parts thereof, into the eyes of the operators.

By the use of my invention all these deleterious features are effectively eliminated.

it accordingly is an object of myinvention to provide a novel form of line control having a resiliently mounted frame associated with the head board or other part of the rig, means being provided for adjusting the transverse movement of said frame, a novel form of carriage equipped with'a casting, grooved to facilitate the reciprocation of said carriage on said frame, being mounted thereon, an anti-friction means in the shape of a movable ball race being associated with said casting, which casting is also equipped with a cut-away portion to permit the ready insertion of the line in the carriage, and the withdrawal therefrom, when the apparatus is installed or dismantled, a pair of cutaway lids being also preferably detachably associated with the top and bottom of said carriage to hold the various parts together. A further object of my invention is to associate with said carriage a novel form of adjustable friction retarding means, held in position by the lids thereof, said means being adapted to coact with part of the frame work of the line control to retard the movement of said carriage as it is whipped back and forth as the line is wound or unwound upon the drum associated withthe rig.

These and other objects of my invention I attain by the apparatus constructed in accordance with that disclosed in this specification and on the drawings formin a part of this appllcation as hereinafter fully set forth. a I

Reference is had to the accompanying drawings, in which similarreference characters denote similar parts. In the drawings, F10. 1 is a top plan viewof my apparatus associated with the usual drum used in oil or other well practice, V

Describing my invention more in detail, 2 indicates the head board, girth, or derrick base, or any other place associated with the well rig, in practice found desirable, and to said head board is secured by any means preferredtwo or more bolts 4, which bolts have associated therewith a channel iron 6, and. a preferably round rod 8, positioned in parallel relation with the channel iron 6, said rod 8 having end portions 10 of tubular form adapted to lie-associated in any desired manner with-a pair of tubes 12. If desired, the rod 8 may be made integral with the tubes 1201 may be secured thereto in any manner preferred.

The channel iron 6 is adj ustably mounted upon the bolts or other members 4 by means of a pair of jam nuts 14, one on each side of the channel iron 4, and screw threaded thereto, as more particularly shown in Fig.

3, the tubes 12 being slidable on the members 4.

Positioned directly in front of the tubes 12, and mounted on the bolts 4:, are washers 16, adapted to be pressed against the tubular end portions 10 by means of the helical s rings 18, surrounding the bolts 4 and abutting against the ad uStable nut and washer construction 20, thus flexibly mounting the members 6 and 8 with respect to the part 2, said construction comprising the frame or frame work of the. apparatus. It

will of course be understood that this ar-.

constructed as shown in Fig. 7, and is equipped with a groove 30 adapted to enga e with the rod 8, the preferably smooth en s 32 being adapted to engage with the fiatend of the channel iron 6.

The central portion of the casting 28 1s bored or otherwise formed with a iole 34 for the reception of the ballbearing des gnated generally b the numeral 36, whlch bearing is prefers. 1y formed of four parts 38, to facilitate the ready assembly and removal of said hearing. The casting is cut away, as at 46 for the reception of the line or cable 24, so that said line maybe slipped into or out of said bearing, a ball race 42 being cut into the parts of the bearing to house the balls 44. Said casting maybe cut away as at 48 for the purpose of lightening the construction.

To retard adjustably the movement of the slide or carriage 22, a friction construction 50, shown separated in Figs. 4, 5 and 8 is provided. Said construction comprises a grooved block 52, grooved at 64 adapted to engage slidably the rod 8, and against said block is positioned a tension spring 54, preferably of leaf form and adapted to be positioncd within the angular member 56, and resting on the projections or ledges 58 and abutting against the side members '62, equipped with cut-out portions 60 to bear against the rod 8, the grooved block 52 with its groove 64 being positioned between said side members, the groove 64 taking against said rod.

To adjust the tension of the spring 54 on the block 52, a set screw or other device 66, provided with lock nuts, is'provided on the carriage 22, as depicted in Figs. 1 and 2. It will of course understood that the specific form of friction retarding means used is immaterial, and that other constructions may be substituted therefor and still remain within the province of my invention.

But for the sake of cheapness of manufacture and simplicity in construction, I prefer to associate said friction retarding means with the carriage and form the same as part thereof,

' frame work, a pair To hold the carri e 22 in position on the 2% lids 68, equipped with slots 70, to permit the insertion and removal of the line 24, are provided, said lids being secured together by any preferred number of bolts or other securing device 72.

To insert the line 24 within the apparatus as it is installed, the top lid 68 is removed by removing the bolts 72, as well as the casting 28 and balls therein, said line being then slipped into place through the slot 70 in the lower lid 68, after which the removed parts-may be replaced and secured together by the' bolts 72. This proceeding'is also gone through when the line is removed.

In operation, the line 24 is positioned within the ball race and engages thev balls 44, and as said line moves upwardly and downwardly, the carriage 22 is reciprocated rapidly on the rod 8 and the channel iron 6, the balls 44 being lubricated continually by the oil on said line. Said carriage also moves transversely with reference to the head board 2, and is held in flexible relation therewith by reason of the springs 18, this construction efl'ectively preventing the cable or line 24 from piling up -on the drum 26. Theball bearing 38 may be readily replaced when worn by removing the bolts 72 and the lids 68. 7

While I have thus described my invention with great particularity, it will be clear that the same may be modified throughout a wide range. I accordingly do not propose to be limited to the exact details of construction shown and described, but reserve the right in practice to make any and all modifications thereof that fall within the scope of the appended claims.
