EEPEGIFICATION forming part of Letters Patent No. 291,837, dated January 8, 1884.

Application filed May 16, 1883. (No model.)

1'0 all whom, it may concern Be it known that 1, WILLIAM E. BROWN, of the town of Elbridge, in the county of Onondaga, in the State of New York, have invented new and useful Improvements inWVell-Drilling Machines, of which the following, taken in connection with the accompz-tnying draw-- ings, is a full, clear, and exact description.

This invention relates to that class of drilling-machines which are usually employed for drilling wells through rock and other hard substances. 7

Theinvention consists in an improved organization of the actuating mechanism of the drill and the supporting-frame thereof, whereby a machine of superior efficiency with great convenience of operation is obtained, all as hereinafter more fully described, and specifically set forth in the-claims.

In the accompanying drawings, Figure l is a side view of my improved well-drilliug machine with its parts placed in position for transportation. Fig. 2 is a view of the opposite side of said machine, showing it in its operative position. Fig. 3 is a detail view of the drill-dropping lever, showing its relation to the rope-drum and cam. Fig. 4: is a detached plan view of the aforesaid lever. Fig. 5 is a plan view of the machine, taken on line a a', with the braces removed, to better illustrate the mechanism; and Fig. 6 is a front elevation of the machine.

Similar letters of reference indicate corresponding parts.

A represents the base of the machine, mounted in the form of a horizontal frame on a suit able truck or vehicle, to render the machine portable.

To each end of .the base A is secured an upright, B B, sustained by braces G 0, running from the rear end of the base to the upper part of the forward frame, B, and by girders D D, extended from the central portion of the braces O to the posts of the aforesaid frames, said braces and girders forming the support for the bearings of the shafts and drums of the machine.

S denotes the shears erected on the end of the machine, and carrying on their upper end the pulleys N and 0, over which the drill-rope Rand slush-pump rope It are extended. These shears l hinge to the top of the frame B in such a manner as to allow them to be swung over and down onto the frame B, as illustrated in Fig. 1 of the drawings, thereby placing'them in a convenient position for transportation when not in use. The foot of the shears is extended to the base Aland adj ustably secured thereto, as hereinafter described.

' E E are braces hinged to the side of the upper portion of the shears, and when erected the foot of said braces rest on the rear end 'of the girder D, and are detachably secured thereto, so that they can be folded close to the side of the shears when laid down in the man-.

the frame B, and thus raise the shears to their upright position, as shown in Fig. 2 of the drawings. A dog, 9, engages the pinion f and prevents the reverse motion thereof, and maintaining the rope R wound upon the shaft F. a is the shaft or drum 011 which the drillrope It is wound, said shaft being provided on each end with a spur-wheel, 1), serving as heads for the drum. A shaft, to, arranged pa allel to the shaft a, is provided with two pinions, b, meshing in the gears or spurwheels 1). One end of the shaft (9 is provided witha hand-crank, c, for transmitting motion to the shaft a, to wind up the drill-rope B when re quired for raising the drill connected to the said rope, the drill being lowered by releasing the crank, the weight of the drill drawing the rope off the shaft a, and the run of the rope being controlled by means of a brakepulley, h, attached to the shaft a, and abrakelever, h, pivoted on the frame-work, and bearing 011 the periphery of the brake-pulley.

To the opposite end of the shaft a is attached a.ratehet-wheel, 7:, with which engages a dog, 7.1, for the purpose of preventing the reverse motion of the shaft a, and the resultant unwinding of the rope during the operation of the machine, said dog" being thrown out of erates.

engagement with the ratchet when the ropeR is to be given out to lower the drill.

At the outer side of the ratchet-wheel is a pulley, h, which is mounted loosely on the shaft a, and back of the pulley is a clutch, p, which slides on a spline on the shaft, and is adapted to engage or interlock with the side of the pulley, the arrangement of said clutch being so common as to not requirea special illustration in this case. It may, however, be seen in Figs. 5 and 6 of the drawings. By means of a lever, g, pivoted on the side of the wooden frame of the machine, the clutch can be thrown in and out of connection with the pulley. The latter is connected by a belt, m, with another pulley, L hereinafter described, and by throwing the clutch into engagement with the pulley h the drum or shaft a can be revolved to wind up the rope R and raise the drill by the motor .of the machine.

H represents the lever which, in conjunction with the cam G, imparts the dropping or plunging action to the drill when in operation, said action being due to the rope It being extended from the drum or shaft a to the sheave (Z on the free end of the lever H, and thence over a sheave 011 the upper end of the shears S to the drill, and the sudden release of the same allowing the drill to drop. The lever H, I hinge on the frame of the machine in such relative position as to bring the hinged end of the lever in proximity to and as near as possible in the same horizontal plane as the rope-drum a, thereby obtaining a constant bearing of the rope It on the foot of the lever during the movement of the lever, and therefore leaving the sheave d, which is pivoted near the free end of said lever and carries the rope It, dormant on its axes during the move ment of the lever, whereas in other analogous drilling-machines the aforesaid lever has been so arranged that the motion of the lever produced an oscillating motion 011 the sheave d, and consequently more or less wear and abrasion of the rope and sheave.

In order to bring the sheave d as near as possible to the under side of the lever H, I construct the lever of two parallel scantlings properly braced and tied together, with a space between them, forming a longitudinal slot, at, in which the sheave (Z is pivoted by a pin passing transversely through the lever and sheave.

At the extremity of the lever H a roller, 0, is pivoted in the slot n,which roller forms an anti-friction bearing, on which the cam G op- This cam is fastened to a counter shaft, 0, and made in the form of a semicircular or segmental arm, the lever H being of such length as to bring the roller 0 to'bear on the cam G near the attached end thereof, when said cam is raised, as shown in Fig. 3 of the drawings, thereby obtaining the maximuni power with theminimum motion at the beginning of the action of the lever. In the descent of the cam Gr it depresses the lever H wit-h gradually accelerated speed until it finally draws its end off from the roller 0 and releases the lever H, the depression of the lever causing a draft on the rope R, and thereby raising the drill, and the aforesaid sudden release of the lever allowing the drill to drop, thus producing the requisite act-ion for drilling wells.

It will be observed that by the arrangement of the roller 6 on the end of the lever H the cam G invariably receives its bearing at that point, and thus obtains the greatest purchase, and actuates thelever without producing jars, while in other analogous machines the roller is pivoted 011 the cam and travels back and forth 011 the lever, and thus in many instances produces jars on the lever and drill-rope. The counter-shaft 0 has attached to it a gear-wheel, 1?, in which meshes a pinion, 1?, on the main driving-shaft 0, the latter being provided with the main driving-pulley M, which is connected by a belt, .9, with the steanrengine or other motor.

R represents the rope which is connected to the slush-pump 'U, for lowering and raising the same in the well, said rope passing over a sheave, O, on the upper part of the shears, in the usual manner, and thence extends to and is connected with a drum, K, which is mounted in hearings or boxes attached to the upper or forward end of the side braces, G C. The journal-bearing l of one of the boxes M is elongated, to allow the drum to swing laterally. The journal which lies in the aforesaid bearing projects at the outside of the box, and with the protruding end is connected a lever, V, which is fulcrumed on the frame of the machine.

A pulley, L, on the end of the drum K, is connected by a belt, J, with a pulley, T, on the counter-shaft 0. Said belt -is of such length that the aforesaid lateral swinging of the drum K will tighten and slaeken the belt; hence by proper manipulation of the lever V, connected with the drum, the latter can be set in motion to wind up the slush-pump rope R, and raise the slush-pump out of the well; or the belt can be slackened, so as to allow the rope to unwind from the drum and the pump to descend into the well, as may be desired.

0' represents a stop in the form of a plate at tached to the frame of the machine and held normally over the lever H when depressed, so as to retain the lever in a dormant position when desired.

A cranked rod, 1', is arranged on the side of the'machine and connected with the stop 9- in such a manner that by turning the cranked rod the stop is drawn out of the path of the lever,to allow the latter to resume its operation with the cam G.

Having described m y invention, what I claim as new,and desire to secure by Letters Patent, 1s-
