I"APPARATUS FOR-DRILLING AND OPERATING WELLS.

SPECIFICATION forming part of Letters Patent No. 685,641, dated October 29, 1901. Application filed J' une 3,1901. Serial No. 62,923. (No model.)

To all whom it mag/*concern- Beit known that I, JOSEPH REID, a citizen of the United States, and a resident of Oil City, in the county of Venango and State of Pennsylvania-,have invented cert-ain new and useful Improvements in Apparatus for Drilling andA Operating Wells, of which the fol'-l lowing is a specification.

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

Steam-enginesl are very expensive for operating wells, rst, because of the cost of the outit; secondly, because of the expense of fuel and the cost of hauling itto the place of use, often difficult of access; thirdly, because of the expense of procuring waterl for the boilers, and, fourthly, because of difficulty of repeatedly moving the outt 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 mechanismlocated 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, un-

certainty cf 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, andv 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 alinement 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, andr reversing mechanism and render the parts readilyseparable for easy transportation, the controllinglevers extending forward to the derrick-floor in the same manner as described in my aforesaid patent.

In the accompanying drawings, Figure 1 is a perspective view of a well-drilling outIit embodying the features of my invention. Fig. 2 is a detail view showing in side elevation the stopping, starting, and reversing gear.. Figs. 3 and 4 are respectively a sectional elevation and a plan, showing the manner of operating the stopping, starting, and reversing mechanism with the constantly-running explosiveengine. Y

A represents the source of power, which is a constantly-running oil or ga's engine.

Bis a stopping,starting, and reversing gear, through the medium of which the source of power is connected with the rigging to be operated, and C represents the well-operating mechanism of the outfit.

The engine comprises the cylinder 1, a coun-` ter-shaft 2,driven by a piston in said cylinder, balance-wheels 3,a pitman 4, connected with a balance-wheel and operating a pump 5 and injecting thc explosive fuel into the cylinder 1, and suitable controlling-valves 5% which regulate the supply of fuel, and consequently the speed of the engine. The regulating- 2 'esami valves are of any suitable type, being connected with the oil or gas pipe and air-pipe, which discharge into a mixing-chamber in quantities and proportions regulated by the valves and whose stems are connected to a controlling lever or rod 5", which extends forward to a point within convenient reach of the operator on the floor of the dert-ick, as fully described in my previous patent.

Located end to end with the motor-shaft 2 is a shaft 6 of the stopping, starting, and reversing member B, connected with the hub of the balance-wheel 3 by a ange-coupling sleeve 7, which is suitably keyed to the shaft 6 and having loosely mounted upon it a wind-- ing-drum or band-pulley 8, through which power is communicated to the well-rig C or the reel thereof, described in my Letters Patent already referred to. ing, and reversing gear B is of known construction and need not be more specifically described here than to state that the reversing-gear may comprise bevel-pinion 9, bolted to the outer end of iiange-coupling sleeve 7, whereby it is driven by the shaft 6, conepinions 10, mounted upon radial axles 11 in a brake-wheel 12, which is loose upon shaft G, and bevel-pinion 13, fixed to the hub 14 of the band-pulley 8, (loose upon shaft 6,) a brake-band 15 being applied to the wheel 12 by a lever 16, as shown in Fig. 2.

The friction-clutch comprises shoes 17, forced into engagement with the periphery of band-pulley 8 or withdrawn from such engagement by the longitudinal movement of the clutch-sleeve 1S on the shaft 6. Vhen no opposition is offered to the revolution of the brake-wheel12 and the clutch S is forced into engagement with the pulley 6, all the parts of the gear B, excepting its brake-band, but including the clutch and pulley, rotate in the same direction as the shaft 6; but if the clutch-shoes 17 are released and revolution of the wheel 12 is opposed through the medium of its brake-band 15 cone-pinions 10 cannot travel about the shaft 2 and rotation of the bevel-pinion 9, with the shaft 6, is converted by the cone-pinions and imparted to the bevel-gear 13 on the pulley in a direction opposite to the rotation of the shaft 6, and the pulley or drum S drives the parts connected with it in a direction opposite to the running of the engine. If neither the brake-band 15 nor the friction-clutch shoes 17 are applied, the band pulley or drum 8 remains stationary, since the cone-pinions 10 will simply travel over the face of the bevelgear 13 proportionally to the rotation that is imparted to said pinions by the gear 9, which rotates at all times with the main shaft 6.

In order to enable the operator on the derrick-floor to apply the clutch-shoes 17 to impart direct rotation to the band-pulley or drum 8 or apply the brake-band 15 to rotate said band-pulley or drum in the opposite direction or to hold said parts in intermediate positions, so that the pulley or drum 8 may The stopping, start,

remain at rest while the shaft 6 is constantly rotated by the explosive-engine, I employ the following means:

19 is a rock-shaft mounted in bearings 2O and moved in either direction by a lever 21, through which all of the mechanism above described is to be controlled and which has a connection running tothe stopping, starting, and reversing lever on the derrick-platform of the well-drilling rig. l

22 is a lever projecting vertically from the rock-shaft 19 and having connection through a link 23 and toggle-levers 24 with the brakeband lever 15, hereinbefore referred to.

25 is a lever projecting downwardly from rock-shaft 19 and having universal connection 26 with one arm of a bell-crank lever 27, fulcrumed at 2S and having its outer end connected at 29 to the clutch-lever 30, which is fulcrumed at 3l and has controlling connection at 32 with the hub 18 of the clutch-shoes 17. These connections are such that when the lever 21 is moved toward the derrick the brake-band 15 will be released and the clutchshoes 17 will be applied; but if said lever is held in an intermediate position both the brake-band and clutch will be released, while by the movement of said lever from said intermediate position in a direction opposite to that first described the brake-band 15 will be applied to call into operation the reversing-gear while the clutch-shoes 17 will be released. These movements of the single lever afford means for starting or stopping or reversing apparatus driven by the continu-` ously-running explosive-engine, and said aetions or changes in running conditions may be effected as gradually as desired by proper manipulation of the lever. The lever 21 might obviously project oppositely to its disclosed position and be moved in directions just the reverse to those above described for accomplishing the purposes stated.

The flange-coupling 7 comprises the depression 33 in the balance-Wheel hub, the centering-boss 34, and flange 35 on the shaft 6, and screws 36.

The combination of features above described accomplishes all of the objects of my aforementioned patent by a direct-eoupled but readily-detachable gear, and the parts are adapted for convenient handling and transportation.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

l. The combination of a well drilling and operating apparatus, a contin uously-runnin g explosive-engine having a main drive-shaft, a power-transmitting shaft in alinement 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 mov- ICO Ito
