'HOISTING MACHINE.

Application filed .enuery 31, 1920. Serial No. 355,458.

To aU 107mm t may concern.'

Be it linoivn that l, CL-Ynn lli-iii, a citizen of the United States, and zi resident of Bartlesville` in the eountyof `Washington and State 5 of Oklahoma, have invented certain ner,7 and useful improvements in lloisting Machines, of which the following is a. speeication.

My invention relates to improvements in hoisting machines, it being more part'culai'- l ly a machinefor hoisting` or pulling the easing, tubing and rods from oil and gas Wells, and it Censis s in the constructions,

combinations and arrangements herein described and claimed.

The foremost object of my inventioiiis to provide combined hoisting machine and coupling, both being embodied in en automobile trucl; or sinnlir vehicle, ind so arranged that when the coupling is joined'in one YWay, the ruoli may be operated such, and when the coupling` is shifting into connection with the hoisting spperatus, the machine may be used for the purposes above speciiied.

l @ther objects and advs will appear in the following specification, reference being had to the accompanying drawings, in Which Figure l is s side elevation of the iinll proved machine, showing the coupling joined with the v-.fell tube hoisting apparatus,

Figure 2 is a side elevation of the hoisting drum and cooperating mechanism,

Figure 3 is a longitudinal section of the hoisting drum,

Figure at is an eiid elevation thereof,

Figure is a cross section taken substantially on the line 5 5 of Figure 8,

Figure is a detail perspective View of the friction clutch head of the hoistingdrum,

.Figure 7 is :i detail perspective view of t ie shifting lever,

Figures 8 and 9 are detail perspective views of the respective cooperating coupling members, and

Figure lO is a detail sectional view show-- ing` hoiv the cooperating coupling members arel fastened together,

ln carrying out my invention l provide a hoisting drum l, Which is mounted either upon the truck chassis 2, upon the frame of any ordino-ry tractor, or in fact, any vehicle Which includes an engine by means of which the drum l may be operated. Briefly deshaft 4l is in connection with the plete 9 of the driven shaft l0, then the truck 2 is driven as suc-h, that is to say, it is used an ordinary automobile truck, the hoisting drum l then being out of operation. yljut When the coupling-.plates are unloosened, by removing the securing bolt ll, in Figure l0', and the coupling plate (3 fastened to the plate 9gv of the shaft l0, then the hoisting drum is rcversed for operation to hoist oil or gas Well casings, tubings and rods, or in feet,ziny other obj ect ivhieh it be desired to hois' There is e. universal joint l2 in the sheft l0 between the coupling plate 9 and the diilerential gear ease 13, on the exposed shaft lei, of which there is i sprocket to which the drive shaft l@ is applied. rllhis chain is also applied to the large sprocket l? nearest the observer in F injure l, Which isv carried by the drum shaft i8, rlhe sprocket and chain mechanism just described, is duplicated ou the other end of the drum shaft 19 as indicated in Figure 3 by the provision of the large sprocket i7 at the left end of the shat't.

l ollers or other suitable bearings i9, support the hoisting drum l on the shaft 1S, it beingv observed that the shaft itself is journalled in bearings 2O and that the hoisting drum l is normally loose on the shaft. lt is not until the clutch head 2l is vforced inwardly by n eans of the lever 22, that the hoisting drum l. is made to rotate With the shaft lfl, The clutch heed 2l at one end and a collar 23, fixed on the shaft et the other end, hold the hoisting drum in the proper position on the shaft.

The clutch hea-d 2l carries paper-surfaced shoes 24 of'suitable materiel, for engaging the correspondingly surfaced recess of the drum as clearly shown in Figure These shoes are resiliently held in place by ineens ot' the spring in Figures 5 and 6. Connections 26 cause the clutch head to move lill with the splined shifting collar 2T on the shaft 18 when the lever 22 is shifted as eX- plained above.

Various positions of the hoisting drum are held by means of brake mechanism including the drums 28 on the ends of the hoisting drum l, the brake bands 29 and the lever 30 which has proper connection 3l to both brake bands.

The operation may be reviewed to advantage. As stated above, the coupling plate 6 of the drive shaft 4- is ordinarily joined .and secured to the corresponding plate 9 of the driven shaft l0, thereby causing the operation of the truck 2 as such. When this arrangement is effected, the truck may be driven about in the ordinary manner, the hoisting mechanism on top, such times being inoperative.

When it is desired to use the apparatus for the purpose of hoisting, the bolts 1l is unloosened and the coupling plates 6 and SFL secured together. By properly manipulating the levers 22 and 30, the hoisting drum 1 can be operated as desired. Of course at this time the truck 2 is practically a fixture, the truck being heavy enough to constitute an ample foundation for the operations of the hoisting drum.

lt is to be clearly borne inmind that it is through the ability to shift the coupling of the drive shaft linto either of the two positions described, that it is possible to have the use of the automobile truck as such in one instance, and the use of an efficient hoisting mechanism in the other instance.

v`While the construction land arrangement of the improved hoisting machine and coupling mechanism is kthat of a generally preferred form, obviously modifications and changes can be made Without departing from the spirit of the invention or the scope of the claims.

I claim 1. A vehicle including a driven shaft with a coupling plate, and hoisting` mechanism With drive gearing including a coupling plate; and a swingably mounted enginedriven shaft with a corresponding coupling plate, interchangeably connectible With either aforesaid coupling` plate, to operate either the vehicle or the hoisting mechanism.

2.y A vehicle `with a driven shaft having a coupling plate provided with a dove-tail recess, and a hoisting mechanism with drive gearing Vincluding a shaft with a coupling plate having a dove-tail recess, and a swingably mounted engine-driven shaft, with a companion coupling plate having a dovetail Wedge insertible into the recess of either coupling plate, with means for securing it, to drive either the vehicle or actuate the hoisting mechanism.

3. The combination, of an engine-driven shaft With a universal joint, and coupling plate having a dove-tail Wedge; ar vehiclecarried driven shaft with a couplingplate having a dove-tail recess; and a hoisting mechanism drive shaft, With a universal joint and coupling plate With a dove-tail recess, the drive shaft coupling plate being secured to either of the latter coupling platos by .fitting the Wedge and'recesses together.

4C. A vehicle including a driven shaft with a coupling member, and hoisting mechanism with drive gearing including a coupling member; and a swingably mounted engine driven shaft with a corresponding coupling member, yinterchan'geably connectible With either aforesaid coupling member, to operate either the vehicle lor the hoisting mechanism.
