Abstract:

My invention relates to apparatus through the medium of which explosive-engines may be combined with ordinary well-drilling and well operating apparatus in a manner to meet the requirements of handling the tools, materials, and implements incident to constructing oil-wells and the performance of work incident to the operating of such wells. Certain improvements in this class of apparatus are described and claimed in my Letters Patent No. 626,933, granted June 13, 1899, in which was described a well-rig having a constantly-running explosive-engine and means for stopping, starting, and reversing its connection with the rig, all under control of the operator on the derrick-floor.

Steam-engines are very expensive for operating wells, first, because of the cost of the oufit; secondly, because of the expense of fuel and the cost of hauling into the place of use, often difficult of access; thirdly, because of the expense of procuring water for the boilers, and, fourthly, because of difficulty of repeatedly moving the outfit from point to point. An explosive-engine offers superior advantages in all of the above-recited particulars; but explosive-engines were formerly not available for these purposes owing to the impracticability of readily reversing them or accurately varying their speed at will or stopping or starting. My previous patent provided means whereby explosive-engines may be used as the source of power employed for performing all of the various kinds of work incident to deep-well drilling; but the control of the transmission of power was by a separate mechanism located at an intermediate point between the engine and the derrick and having belt connection to each. This particular embodiment of my patented ideas is objectionable in some cases, because of the extra amount of mechanism and belting employed, which entailed original expense, uncertainty of operation, and bulkiness in transportation. The parts of an outfit must be as few as possible and such that they can be readily handled without special means for lifting and may be carried on comparatively small vehicles Without danger of injuring shafting and other parts. Long shafting cannot therefore be used with satisfactory results.

My present invention consists in a novel construction and arrangement of the stopping, starting, and reversing mechanism in combination with the other parts of the well drilling or operating rig set forth in my aforesaid Letters Patent, the above-mentioned mechanism being arranged in alignment with and directly coupled to the main shaft of the explosive engine, so that all intermediate belting is disposed of and so constructed as to make a novel means of connection between the said stopping, starting, and reversing mechanism and render the parts readily separable for easy transportation, the controlling levers extending forward to the derrick-floor in the same manner as described in my aforesaid patent.

Claims:

l. The combination of a well drilling and operating apparatus, a continuously-running explosive-engine having a main drive-shaft, a power-transmitting shaft in alignment with said main drive-shaft, a coupling detachably securing the transmitting-shaft directly to the main shaft end to end, and a stopping, starting and reversing clutch on said transmitting-shaft and suitable means including a brake pulley and band for the direct driving connection and connections from the movable member of the clutch and the brake band.

2. The combination with a well drilling and operating apparatus, of a continuously-running explosive-engine having a main driveshaft, a power-transmitting shaft in alignment with main drive-shaft, having a drive-pulley or drum, a coupling detachably securing the transmitting-shaft directly to the main shaft end to end, a stopping, starting and reversing clutch including a brake wheel and band on said transmitting-shaft, and suitable means to operate the said clutches extending forward to the derrick-floor, consisting of rods extending from the clutch and brake-band to the derrick-floor, and a lever having connections including other levers, through which it controls the operation of the clutch and brake-hand and moves said reversing-gear and clutch simultaneously and throws one into and the other out of driving relation to said pulley or drum.

3. The combination of a Well drilling and operating apparatus, a continuously-running explosive-engine having a main drive-shaft, a power-transmitting shaft in alignment with said main drive-shaft, a coupling detachably securing the transmitting-shaft directly to the main shaft end to end and stopping, starting and reversing clutch on said transmitting-shaft and suitable means to operate the said clutch extending forward to the derrick-floor; said clutch and operating means consisting of a transmitting pulley or drum loose upon said shaft, a reversing-gear on said shaft thrown into and out of driving relation with said pulley or drum, a wheel concentric with said shaft and a brake-band applied to said wheel, a brake-band lever for applying said brake, a friction clutch forced by a movement longitudinally to the shaft into and out of driving relation With the transmitting pulley or drum, a bell-crank lever having one end presented in a direction to impart said longitudinal movement to the clutch, and a rock -shaft parallel with the continuously rotating shaft having oppositely projecting levers connected respectively with the brake-band lever and with the bell-crank lever and thereby adapted to impart movements transversely and longitudinally of the rotating shaft and throw the reversing gear and friction-clutch alternately into and out of driving relation to the transmitting pulley or drum.
