' LEWIS PIRDUN AND JOSEPH P. BURKE, or SAND SPRZZNGS, OKLAHOMA,

DRIVING AND CONTROLLING THE OPERATION or REELS.

' To all whom it may concern it apper'tains to make and use the same.

This invention relates to improvements in means for driving and controlling the operation of reels, and more particularly to such as are applicable for use with drilling rigs in operating the boiler in oil, gas or water drilling, but which may be employed for other purposes where it is desirable to accurately and economically operate and control a winding reel;

The Object of the invention is to provide mechanism of the character specified in Which a reel, such as, a sand-reel, shall be driven-by belting rather than by friction as heretofore proposed, so that the amount of power necessary to drive the reel shall be reduced to a minimum; so that'the life of the band wheel shall be prolonged; to eliminate the disadvantages of a friction drive and thereby decrease the amount of vibration of the rig; so that the reel may be driven at a high rate of speed, and so that the cost of upkeep of mechanism of the character to which the invention relates, shall be reduced to a minimum.

With these and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure l is a plan view of mechanismshowing an embodiment of our invention; 2 is a view in elevation; Fig. 3 is an enlarged view partly in section showing the sand reel and parts associated with the shaft thereof; Fig. 4 is a view in section on the line 4-4 of Fig. 3, and Fig. 5 is a View shOW- ing the brake.

While our improvements are adaptable for various purposes, we have shown and will describe the same as employed to operate and control a sand reel to Operate the bailer for well drilling.

1 represents framework such as employed Specification of Letters Eatent. 1" F3,t]{31ilj(5d Aug. 30,

Application filed November 24, 1920. Serial N0. 426,151.

in well drilling apparatus and on this framework, suitable bearings are provided for the shaft :2 of a large belt or band wheel said shaft also carrying tug wheel Nearone end of the framewor, a shaft 5 is mounted in suitable bearings and carries a sand-reel 6 to receive the line or cable of a bailer (not shown), and on this shaft, a pulley Y is loosely mounted and adapted to be connected to rotate therewith'by means of a suitable clutch indicated at 8. The shaft 5 also carries brake wheel 9, over which a brake band 10 passes,-one end of said brake band being secured to one of he frame timbers and attached at the other end to a crank 11 of a shaft 12 mounted in suitable bearings on the framework.

A belt passes over the large wheel 3 on the shaft 2 and thesmaller sand-reel pulley 7 on the shaft 5 and serves to transmit motion from said large wheel to the pulley? for driving the sand reel; The

large belt wheel 3 is driven by a belt 14 receiving motion from an engine pulley 15 and passing over the belt wheel 3 in contact with the belt 18 thereon, and thus the sand reel will be driven by belt gearing and the objectionable features incident to the use of friction driving means heretofore employed will be obviated.

A belt-tightener 16 is provided for'the belt 13 which drives "the sand-reel, and the armsof this belt-tightener are secured to the crank-shaft 12. I

A bracket 17 is located near one end of the framework and provides a support for a lever 18, the latter being pivotally connected above its lower end to said bracket as indicated at 19. The short arm 20 of this lever is connected by links 21 with an arm 22 on the crank shaft 12, so that when said lever is moved, the belt tightener and brake band will be operated. The lever 18 is also connected, by a link 23, with one arm of a bellcrank lever 24, the other arm of which is bifurcated and engages the clutch for shifting shown in full lines in Fig. 2, the belt tightener will be released, the clutch 8 disengaged and the brake 910 set, and the sandreel will be held by the brake and thus be prevented from unwinding.

In order to cause the sand-reel to wind the cable thereon, the operator will shift the hand lever 27 to the dotted line position shown in Fig. 2; whereupon the brake will be released, the clutch engaged with the pulley 7 and the belt-tightener moved to tighten the belt 13. Motion will now be imparted to the sand-reel to wind the cable. When the reel is used for running the bailer in well drilling, the operation will be as follows: The bailer being in the bot-torn of the hole, the operator will more the lever 2. to the dotted line position shown in 2- and thus throw the reel into operation as preby explained. to lift the bailer out of the hole. T

flu

ihe operator will then more the lever 2'? to ncutra position, v m, half way between the two positions shown (in Fig.

thus releasing the bralre and belt tightener and setting; the clutch in neutral position and thus permitting the bailer to unwind the cable by its own weight.

lVe have found the apparatus herein described to be decidedly easier to handle and runs more smoothly than in the case of tricticn driven reels; that vibration to the rig is reduced to alnininiuin, and that it is economical in the use of power.

Various slight changes might be i made in the details of our invention without departing from the spirit thereol or limiting its scope and hence we do not wish to restrict ours-elves to the precise detailsherein set forth. i

Having fully described our invention what we claim as new and desire to secure by Letters-Patent, is v lrThe combination with a reel, a pulley for rotating the same, a belt wheel, and means for driving the latter, of a belt pass ing over said belt wheel and pulley, a belt tightener for said belt, a clutch for operatively connecting said pulley with the reel and disconnecting it therefrom, and a brake for saidreel, of manually operable controlling means common to said belt-tightener, clutch and brake.

2. The combination with a shaft, a reel thereon, a pulley loose on said shaft, a belt wheel, and a belt passing over said belt wheel and pulley, of a clutch for connecting said pulley to the shaft, a belt-tightener for said belt, a brake wheel on the shaft, and a brake band to engage said brake wheel, of a lever pivoted between its ends, connections between one of said lever and said belttightener and brake band, connections between the other arm or aid leverand the clutch, and means whereby said lever may be manually operated to actuate the clutch, belt-tiglrtener and brake band.

3. The combination with a shaft, a reel thereon, a pulley loose on said shaft, a clutch for connecting the pulley with the shaft, a belt wheel, a belt passing over said belt wheel and pulley, a brake *heel on the shaft, and a brake band on said brake wheel and fixed at one end, of a crank shaft having its crank connected with the other end otthe brake band, a belt-tightener for said belt connected withsaid crank shaft, an arm on said crank shaft, a pivoted lever, a connec tion between said pivoted lever and said arm, connections between said pivoted lever and clutch, and means whereby said lever maybe manually operated.
