as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification. v

' My invention relates to hoisting machines,

and particularly to portable machines of this class for use in raising sucker-rods, tubing or other parts from oil or other classes of wells, or for lowering such parts therein, but it is not restricted to such use. a

The object of my invention is the provision, in combination with a vehicle or other portable mount, of simple and efficient means for raising the mast from or lowering it to reclining position relative thereto and shifting it to enable it when raised to be positioned at either side of the vehicle as the position of the parts to be operated on rela i which,

Figure 1 1s a cross-sect1on of'the vehicletive to the vehicle or mount may require.

The operation, construction and arrangement of the parts of the invention are fully described in the following specification, and illustrated in the accompanying drawings, in

associated with my invention with the mast set 11 in operative position at oneside thereof, the upper portion of the mast being broken away. Fig. 2 is a side elevation thereof with themast and operating mechanism shown in dotted lines in reclining position on the vehicle. .Fig. 3 is'an elevation of the upper portion of the mast and asso ciated parts. Fig. 4 is an elevation of the upper portion of the mast with a ortion of the lower section in longitudina section. Fig, 5 is an enlarged longitudinal section of a portion of the lower mast section and the base portion of the upper mast section, and Fig, 6 is a transverse section on the. line in Fig.

Referring to the drawings, 1, 1 designate two beams which are supported by the running gear of a suitable vehicle and have their ends rigidly connected by the front. and rear (Toss-pieces 2, 2, which preferably project above the beams and form pillow-blocks for the purpose hereinaftc: described.

Connecting the

beams

1, 1 intermediate their ends and preferably at or near the center thereof is a latform 4, to the top of which is suitably swivelcd a block 5 for horizontal ivotal movement. Hinged to the top of the lock 5, as at 6, for oscillation in avertical plane is a second block 7, from one side of which rigidly project the spaced bars or side frame pieces 8, 8. These bars each hinge at their outer ends, as at 9, to the lower crosspiece or base of a frame 10 to which the lower end of the mast or pole 11 is fixed in a suitable manner, thus enabling the mast to be elevated relative to the frame formed by the block 5, bars 8, 8 and base of the frame 10, as shown in Figs. 1 and 2, or placed in reclining position thereon, as shown by dotted lines in Fig. 1. The mast. when in reclining posit-ion rests on a pillow-block 12 on the top of the block 7. two sections, which are secured together in a manner to permit longitudinal adjustment thereof if desired.

Mounted longitudinally of the block 5 on the side thereof opposed to the bars 8, 8, is a shaft 13, which has its ends adapted to receive a crank and carries two rack-pinions 14 one of which is disposed at each side of the mast 11 when in reclining position. A rackbar 15 cooperates with each pinion, and each is slidingly held in engagement therewith by a guide 16, which is loosely carried by the shaft to enable its bar to have a pivotal as well as a longitudinal movement. Each rack-bar 15 carries the two spaced sheaves 17, 17 at its upper end between which is passed a cable 18, the upper or mast end of which is attached to the mast or pole ,11 above the end of the rack-bar when in elevated position, as at 18 in Fig. 3, while the lower end thereof attaches to and is ada ted to wind on a windlass 19, carried by the ans 8, 8 transverstdy thereof. The windlass 19 is adapted to be turned by a crank and carries a ratchet-wheel 20 with which a pawl 21 engages to normally prevent an unwinding of the two cables 18 therefrom. Attached to the upper end of each rack-bar 15 is one end of a guy-cable 22, the other end thereof being carried down in advance of the mastframe 10 and attached to the base thereof, as at 23.

When the mast andits base-frame 10 are in reclining position on the swinging-frame Each bar 8 is shown as comprising which carries the base-frame, the base end of the mast is counterbalanced to a consider able extent by the other end thereof so that the outer end of the swinging-frame can be easily raised to horizontal osition from the lowered position shown in igs. 1 and 2 and swung aroundwith its. load to enable them to rest on the top of the vehicle longitudinally thereof. When in this osition the baseframe 10 rests on the pil ow-block 2 of the vehicle while the forward ortion of the mast rests on the other pillowlock 2 thereof, as shown by dotted lines in Fig. 2. One pillowblock 2 is preferably hinged, as at 8, to enable it to be swun down when the mast is being swung aroun and then to be raised beneath the mast to cause the art resting on the other block to be forcefully held to its seat to prevent vertical oscillatory play of the mast when the vehicle is in motion.

The hoi ting-cable 24 of the machine passes up 0 er a sheave 25 at the top of the mast and then down and attaches at one end to a drum 25, which iscarried by the mastframe 10 transversely thereof, and has power applied thereto in any suitable manner. a

The mast 11 is shown as having an upper section 11, which loosely telescopes wit the lower section 11 to permit relative longitudinal adjustment thereof. An adjustment of the sections is effected through the medium of a cable 26, which has one end attached to a Windlass 27 carried by the frame 10, thence passes up over a sheave 28 near the upper end of t e lower mast section, thence down into said sectlon between it and the upper section and under a sheave 29 carried at the lower end of the upper section, the other end of the cable being then carried up between the two sections and attached to the lower section as at 30.

31 designates a clutch which is carried at the upper end of the lower mast section and cooperates with it and the upper section to.

maintain them in fixed adjustment as soon as strain is applied to the upper section, thus relieving. the adjusting-cab e 26 of all working straln on the'mast. The clutch may be re eased by a downward pull on the outer end of the lever 32. In raising the mast to operative position from the horizontal reclining position shown by dotted lines in Fig. 2, the pillow-block 2, which is hinged, is swung down to enable the portion of the mast in engagement with the other illow block to be tilted free therefrom and t e mast to be then swung transversely of the wagon with its base on the desired side thereof and in contact with the ound, as shown b full and dotted lines in ig. 1. The rackars 15 are now elevated and run out by a turning of the shaft 13 in the proper direction until the ycables 22 are drawn taut, as shown, an are rocked in such osition by inserting locking pins 15 throng apertures in the guides 16 and registering apertures 15 in the rackbars. The Windlass 19 is now turned to shorten the cable 18 to effect a raising of the outer end of the mast, and the rack-bars are further run out as the raisingoperation may require. As the mast is raised from the position shown in dotted lines in Fig. l the cables 18 work over the lower sheaves 17 of the respective rack-bars, and by the time the mast has been elevated to vertical position the upper sections of the cables 18 have swung over into engagement with the upper sheaves 17, thus tending to steady and stop the forward movement of the mast when it has reached a predetermined point past a "vertical. It will, of course, be understood that guy-ropes are attached to the upper end of the mast to steady it when past or in vertical position.

It is apparent that I have provided a simple and highly eflicient means for raising and lowering the mast and enabling it to be placed in reclining osition longitudinally of the vehicle or raised at either side thereof as the position of the article to be operated on relative to the vehicle may require.

I wish it understood that I do not desire to be restricted to the exact details of construction and arrangement of the arts shown and described, as obvious modifications will be apparent to persons skilled in the art.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,-
