WINDLASS AND CONNECTION.

SPECIFICATION forming part of Letters Patent No. 598,166, dated February 1, 1898.

Application filed June 24,1897.

To all whom it may concern Be it known that HARLIN J. TRACY, residing at Salamanca, in the county of Cattaraugus and State of New York, have invented certain new and useful Improvements in VVindlasses and Connections, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to windlasses for drawing or straining surface lines and the construction of such a Windlass with'the pullwheel used for drawing such lines in pumping oil-wells, 85c.

As shown in the patent of Lufkin, No. 539,746, dated May 21, 1895, a large wheel is used for driving the pumps of a number of oil-wells from one engine or motor. This large wheel or disk is called the pull-wheel, and this pull-wheel is generally mounted on a solid foundation only a little above the ground, and the hub on which the wheel oscillates extends a little above the flat face of the wheel. Quite a number of cables are generally attached to the wheel and extend in various directions,- and when the wheel is rocked back and forth all these cables are drawn and loosened alternately, and, as will be readily understood, each cable may work a pump some distance away. It is necessary that all the cables should be drawn taut or on the pull-wheel. When a cable breaks or is loosened for repairs or other purposes, the pull-wheel neednot be stopped. The wheel may go on operating all the other cables until a convenient time for stoppage for the attachment of the broken cable. \Vhen the cable is again attached, it must be drawn to the proper tension.

To enable each and all the cables to be properly strained is the object of my invention.

Figure 1 is a partial elevation and partial section of a pull-wheel with my Windlass attached. Fig. 2 is a perspective View showing the main parts of my invention ready for adjustment on the pull-wheel. Fig. 3 is a perspective View showing the machine in operative position. Fig. 4 is an end view of c'levis or pulley. Fig. 5 is a side view of clevis or pulley. Fig. 6 is an elevation of the brace.

port or anchorage B in any usual manner and has a number of holes near its rim. A metal ring, collar, or sleeve 1 is the cent-er of my device and passes overor around the hub H of the pull-wheels A frame 2 is hinged or pivoted to a base-piece b, which is swiveled to collar 1 by pintle c. The base-piece b is pivotally united to the frame 2, as by pivots d, so that the frame can turn down or be raised up. This frame has two side pieces 4 4, and the frame forms or supports the bearings of the Windlass-drum 5 and of the crank-"shaft or'counter-shaft 6. The Windlass-drum has a large driving-gear 7 firm] y connected, and the crank-shaft or counter-shaft has a pinion 8 engaging this large gear. The crank 9, outside the frame, serves to turn the'countershaft and thereby the large gear and the winding-drum. If the crank be six times as long as the diameter of the pinion and the drum be six times smaller than the large wheel 7, then a given power at the crank should exert thirty-sixtimes as much at the winding-drum, and these or other suitable proportions may be employed.

The winding-drum has a cable 10 connected therewith, which cable may be connected to any one of the cables driven by the pullwheel,so as to apply the proper strain thereon.

As the ring 1 may be turned on the hub of the pull-wheel, moving and replacing bolts 6, as shown in the drawings, or by other suitable adjustment, the frame and its windingdrum may be made to face in any direction. The frame is held upright against any pull on the indlass by the forked brace-rod 12,which has one arm of its fork connected by a crosspiece 30 to each side bar of the frame. The brace-rod proper is in two parts 12 and 13 and connected by a turnbuckle 14, engaging right and left threads. The lower or outer part of the brace has a bolt 15, coupledthereto by loop-coupling, and this bolt 15 may pass through any one of the holes near the rim of the pull-wheel and be secured by a nut below the wheel. It will be seen that this affords a very strong and .at the same time flexible attachment or brace by which the frame 2 may be held in upright position, and that its inclination may be adjusted by the turnbuckle.

Looped to the collar or base of the frame there is a derrick-arm 2O. At the outer end of this arm there is a clevis 21, having a socket 22, in which the end of the derrickconnected to its inner end. This eyebolt can be secured in any of the holes at the edge 7 of the pull-Wheel nearly opposite the brace 12,

and in this way the derrick-arm will be held, with the clevis turned in almost any direction, as the looped coupling of brace 24 and the socket'on the clevis permit the clevis to be moved about the derrick-arm as a center and attached at any suitable angle to present the pulley in convenient position to draw to advantage.

When in use, the Windlass can be secured and braced, substantially as indicated in Fig. 1. When not in use, the derrick-arm may be turned into upright position by detaching eyebolt 25, and the derrick-arm can then be tied back against the frame, or by detaching the brace both the frame and derrick may be turned down on the pull-wheel as nearly as wheel 7 Will permit. Thus the Windlass may be gotten pretty well out of the way without removal from the pull-Wheel and can be adjusted to any needful position and held with great firmness on the wheel.

It will be understood that changes Within the scope of the claims may be. made without departing from my invention.

I claim- 1. The combination with the pull-wheel at a central pumping-station having holes near its edge of a base adj ustably attached to said Wheel, a Windlass-frame pivoted to said base, and a Windlass thereon, and a brace extendsaid brace in one of the holes in the wheel,

substantially as described.

2. The horizontal pull-wheel, the Windlass swiveled centrally of said wheel and having a brace extending to near the wheel-rim, the derrick-arm extending from the base of the Windlass in opposite direction from the'brace, and a link braced by the derrick-arm and connected to the wheel-rim, and the cable passing over a support on the link and so to the windlas's, all combined substantially as described.

3. In a cable-straining device for attachment to pull-wheels, the Windlass and its supports constructed for connection to the hub, the derrick-arm pivotally connected to the Windlass-base, a clevis at the outer end thereof, the brace-rod loosely connected to said clevis at one side of the derrick-arm, the sheave in the clevis at the other side of said arm, and a bolt loosely connected to the clevisbrace and extending into one of the holes in the pull-wheel, all combined substantially as described.

4. In a cable-straining device, the base or central support, the Windlass havingits frame pivoted thereto, the forked brace pivotally connected near the top of said frame and provided with a turnbuckle and attaching-bolt, a derrick-arm pivoted to the Windlass-support, and a clevis at its outer end, with a brace loosely connected thereto and a sheave in said clevis, all combined substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
