`To all whom t may concern:

Be it known that I, CLYDE S. WRIGHT, a citizen of the UnitedV States, residing at Toledo, in the county Aof Lucas and State of Ohio, have invented new and useful'Im- -provements in Pulling-Machines, of which A It isthe principal object of this invenl tion to provide a mechanism, incorporated in 4the pulling machine, by which the latter may be raised from a substantially horizontal position on a truck to a substantially vertical osition with the expenditure of ,'comparatlvelysmall force. Another object is to mount the machine so low on the truck.

v as to' make a safe and stable load during its '.j transportation. Another object is to pro- 'vide means for leaving thetruck on the i ground during the hoistingl of the machine,

so that the truck .may be repaired, if required, without loss-of time, while the pullf ing machine is in use.. The truck may be i v'used also as a brace for steadyingthe base of the mast afterits erection. o

Referring to thel accompanylng drawings, Figure 1 is-a side elevation of m pulling machine. in position on its truck or transportation; Fig. 2, a sidel elevation showing the mast partly elevated; Fig. 3, aside ele- Vation showing the mast fully elevated ;.Fig.',-

4 a top plan view of Fig. 1; Fig. 5,a broken sectional View .showin the truck'and the lower end of -po e frame, the truck i. wheels being omitted and parts being in section; and Fig. 6, a side View of Fig. 5.

On the drawings, 1 representsa skeleton A mast supported on thecross-piece 2 of the gin-pole frame having the upright side posts 3, one on each side ofthe mast. Each end ofthe cross-piece has adownwardly extending projection 4 with an open-endedrecess 5 in which the axle 6 of the truck rests. 7 represents the truck wheels on the ends of the axle. The cross-piece 2 is placed Specification of Letters atent.

10 to the said bracket, which is secured to which supports the Winding drum 11.

The side posts 3 of the gin-pole frame have in line with themselves, the supplementary masts or gin-poles 12 which are' substantially vertical when the mast 1 is horizontal, or on the truck. The gin-poles 12 pass loosely through the clips or guides 13 on the sides of the mast 1. A sheave 14 is mounted on the top of each gin-pole 12,

and a second sheave 15 is carried by thebracket 16 on lthe .upper comer-members vof the mast 1, the

sheaves

14 and 15 being in' line with the top of the mast 1. Hoisting lines 18 extend from the points17 beneath and back of .the gin-poles 12, over Vthe Asheaves 14,' thence under the sheaves 15, and Lover ,the sheaves 19, one being connected to each side of the top of the mast 1. The

lines 18 are preferably a single rope or cable, which is looped on the sheaveblock 20, which carries the line 21 for hoisting the mast `1.

The drum 11 may be' operated by cranks 22 on the ends of the drum-shaft 23, or by any other suitable power. A hoisting line 24 extends from the drum overthe pulley 25 on the top of the mast 1, and-has one end the hea-vier end of the mast, that is, the end l connected to apparatus such as 26 to be pulled from' the' well 27. The other end of th'e 1ine,24 passes under vthe drum 11 and is connected to a suitable source of power,

or it may beY connected to the drum and operated by the handles 22.

' The pulling machine mounted on the A truck as shownon Fig. 1 is drawn to the vicinityof a well, as 27, from which tubing, rods, and the like-are to be pulled. An

.abutment composedv of one or more stakes 28, for example, is made near the Well. ,The machine is placed in li-ne with the well and the abutment,and tilted with the drum end down and in `engagement .with the abutment and Athe ground ora temporary Hoor 29 on the ground. The line 21'is then operated to put strain'on the lines 18, the first effect' of which is to raisethe mast 1 up on the gin-poles 12, thefoot of the mast moving on the abutment and ioor as on a pivot. This first effect brings the mast from the position shown on Fig. 1 to that shown on Fig. 2, where the mast 1 is drawn up tev the top of the gin-poles 12. The second los y e'ect of theroperation of the line 21 is to raise the mast 1 together with the gin-pole frame, the links 9 and the gin-poles 12 to the vertical lposition shown on Fig. 3, the mast 1 and the gin-poles 12 being held together by the lines 18, the' mast12, and the bracket 15. When the mast 1 is raised to its upright position (Fig. 3), it is suitably anchored, the

lines

18 and 21 forming one anchor line. V3() represents another anchor line.

It is to be'noted that the truck remains on the ground when the gin-poles are raised. The links 10 may be disconnected from it, if desired, in order that the truck may be used for some other purpose during the pull ing operations. The truck or the links 10 may be used to brace the mast 1.

I claim- 1. In a pulling machine, a main horizontal mast, an upright mast having its upper end above the main mast and between the ends thereof, a single hoisting line, and sheaves carried by the masts and threaded by the line, whereby, when the base of the main mast acts as a pivot, the travel of the line first raises the first mast 'on the second, and, after` the `lmain mast reaches its limit of travel on the second thetop of the main mast, whereby, when the base Aof the main mast acts as a pivot, the travel of the line first raises the first mast on the. second, and, after the main mast reaches its limit of travel on the second mast, the -continued travel of the line youd the second mast, and another sheave being on the main mast near the second mast, and a hoisting line passing overthe first sheave, beneath the third sheave and around the second sheave, whereby the line first causes the main mast to travel up the second mast while the base of the main mast serves as a pivot and, when the main mast reaches the limit of travelon the second mast, the line, pulling on the second sheave, then raises the main mast on said pivot to an upright position.

4. In a portable pulling a frame resting thereon and comprising upright posts and a cross-piece connecting them, a main horizontal 'mast supported by the cross-piece, a pair of upright masts having their lower ends carried by the posts and their upper ends extending above the main mast and at opposite sides thereof, a sheave at the top of each mast, sheaves on the main mast near the upright masts, and a pair of hoist lines connected at one end gto: a fixed support and each threaded over a sheave at the top of an upright mast, beneath the sheave on the main mast and adjacent to the first sheave, and around the sheave at the top of the main mast.
