DRILLING- ACHINE.

Specification of Letters Patent.

Patented. Nov. 4, 1913.

Application filed January 6, 19121 Serial No. 740,499.

To all whom it may concern Be it known that we, FRANK STEVENS and FREDERICK Srionnn, citizens of the United States, residing at Roundup, in the county of Musselsliell and State of Montana, have invented certain new and useful Improvements in Drilling-vlachines, of which the following is a specification.

The present invention relates to improve- 19 ments in boring and drilling machines especially adapted for use in connection with Artesian and oil wells of standard type.

The essential object of the invention is the provision of a machine for this purpose which is more efficient in its operation,

facile in its manipulation and control, and capable of easy and rapid adjustment of its operating parts while in actual use.

The invention consists in certain novel features and combinations and arrangements of parts, especially in the movement of the boring or drilling tool, feeding the rope to which the tool is attached, and in the provision of an advantageously arranged A tension device in connection with the stroke so according to the best mode so far devised for the practical application of the princi ples.

Figure 1 is a side view of the machine complete. Fig. 2 is a detail, front view of j the upper or top portion of the tower of Fig. 1. Fig. 3 is a plan view of the principal operating parts of the machine, other parts being omitted for convenience of illustration. Fig. 4 is a sectional detail view showing the operating parts of the invention. Fig. 5 is a transverse sectional view showing in elevation, the tension device used in connection with the stroke mechanism, or heater shaft. Fig. 6 illustrates in detail section the device for adjusting the stroke of the tool, and shows its relation to the beater shaft. Fig. 7 is a transverse sectional view through the supporting frame, showing the beater shaft and its ac- Fig. 8 is an enlarged sectional detail of the stroke adjusting device. Fig. 9 is an enlarged sectional detail view of the rope feed device.

In the preferred embodiment of the in t5 vention the machinery is mounted upon a frame 1 provided with wheels 2 for convenience in transportation, and the motor 3, shown in conventional form might well be used to propel the vehicle as well as drive the fly or drive wheel 4, to which it is connected by belt as indicated in dotted lines 5.

A tower 6 located at the front of the apparatus comprises a convenient ladder, and is braced and connected to the frame by the brackets 7 and brace 8. A pulley 9 is journaled at the top of the tower over which the too-l rope 10 is passed, and a guide loop 11 for the rope is attached at a convenient point below the pulley. A tool 12 of usual or standard type is attached in the ordinary manner at the end of the rope, or this tool may be a special tool fashioned par ticularly for use with this machine.

The rope 10 is fed from the drum 18 whose shaft 14 is journaled in the frame 1 and is provided with a feed controlling device including the screw 15 that is actuated from the handle 16. In Fig. 3 this feed device is shown out of operation, but when in position for use the screw or worm 15 is in mesh with the complementary gear wheel 17 on the drum shaft 14. In Fig. 9 a spring pressed detent 18 is illustrated (the spring is indicated in dotted lines 18) as pivoted at 19 in a bracket 20, and the bracket, which is hollow or open, has passed therethrough the screw bar 21. The bar 21 in Fig. 9 is in the same position as in Fig. 3, i. e. inoperative and is so held by the detent. If it is desired to turn the drum 13 on its shaft, the detent is released by a pull on the draw rod 22, and the screw bar is shifted laterally so that the worm engages the gear wheel 17 the draw rod is then released and the detent returns to position to lock the bar against lateral movement; and the crank or handle 16 is turned. This movement rotates the worm, and through it, the gear wheel and drum, to wind or unwind the rope as the case may be. This movement of the drum is accomplished manually by an operator standing at the front of the machinery, but it will be understood that the drum may also be power driven. The power drive of the drum is taken from the driving shaft 23 by means of the clutch 24 and gear wheels 25 and 25, the latter located on the drum shaft, and the clutch being operable through the forked handle 26 as usual. A brake 27 of the usual band type may be used in connection with the drum to control the drum when it is running free. It will be underplates .47.

. frame 1.

stood that the fly ordriving wheel is loose on its shaft and actuates the drum only when the clutch 24L is coupled. Atthe opposite side of the fly wheel on the driving shaft, a second clutch 28 is located, and this is designed to bring the stroke or rope impact device into operative relationship with the driving wheel. The clutch 28 is keyed to the shaft which is provided with a crank 29 upon which the pulley 30 is journaled, bearings 31 being provided for the crank.

In Fig. 4 the position of the rope with relation to the drum and crank shaft is clearly shown. Here the rope is illustrated as passing from the drum over a tension device, and a stroke adjusting device to the beater. This tension device comprises a pair of rolls or rollers '32 and 33 rotatable on their respective shafts 34: and 35. The shafts are supported in side plates 36 and 37 and the upper shaft 34 provides a suspen sion means for the plates about which the tension device may swing. Each side plate is provided with a lower extension to which a spring actuated bar 38 is pivoted at 39, the bar being passed through a bracket 4.-() and provided with a tension spring 4-1. A nut 42 is used to compress or permit the spring to expand when suitably operated.

The stroke adjusting device comprises a pulley wheel or roller l3 which is journaled in a carriage tat provided with side flanges 45 that travel in grooves 46 in the side guide The guide plates are suspended from theframe 1, and the carriage has incased in its hollow' head, the enlarged end 48 of the screw bar 49 which is threaded in the complementary block 50 attached to the Thescrew bar49 may be turned by means of the handleor crank 51 to cause the carriage to move toward or away from the front of the. machine.

In operation, the machinery is driven from the motor and the proper clutch having-M closed, the rope may be wound upon the 45 drum, as described. The drum clutch is then thrown out, and the clutch for the beater shaft is thrown into operation, after the boring tool has been placed in operative position. beater as it revolves is to strike the rope l0 and thus lift the tool. The continued revolution of the crank permits the tool to fall thus making a stroke. As the boring The function of the 50 v proceeds, the drum may be revolved by hand 55 and the rope unwound to lower the tool as described. The slack is taken up at all times, and a tension is provided by the ten; sion device.

The length of the stroke may be governed and gaged by moving the stroke gage in or out, thus decreasing or increasing the stroke at will, as will be understood.

Having thus fully described our invention, what we claim is 1. In a boring machine, the combination with a drum, rope, and tool, of a rotary im-i, pact member carrying a pulley, a pivoted frame having a roller over which the rope passes between the drum and impact memher, and a movable carriage having a pulley over which the rope passes between the 7 frame and the impact member, whereby the. stroke of the impact member may be varied.

2 In a boring machine, a stroke adjusting device comprising a movable carriage and l a pulley thereon, and a screw bar In testimony whereof we ailiX our signatures 1n presence of two witnesses.
