lpulley 17 and also provided Aupon one of its 'p the drill-rope, which supports the tools. The `other end of the drill-rope is reeled, as in the Be it known thatI, GEORGE DUDLEY LooMIs, a citizen of the United States, residing at Tifhave invented a new and useful Hand Well- Drilling Machine, of which the following is a specification. My invention relates to well-drilling machinery, and particularly to a machine adapted for actuation by hand-power; and the object in view is to provide a simple, comparatively-inexpensive, and efficient construction of different weights may be counterbalanced to facilitate the manual operation thereof, and in connection therewith to provide simple means for paying out the drill-rope.

The invention also has for its object to provide a construction in which `the operator will move the drill downwardly bygrasping the drill-rope or the shank f the drill, the return Similar reference characters indicate corresponding parts in all `the figures of the drawings. The derrick which -is illustrated in the draw-y ings is of the ordinary construction, comprising a ladder and suitable backbraces 11,

the derrick to direct the drill-rope 13 when raising tools from the well.` Projecting forward from Vthe ladder is a bracket 14, upon which by means of a pin 15 is fulcrumed a walking-beamer rocking lever 16, provided concentric with the pivot 15 with a directionarms with a direction-pulley 18, which is located over the well and which is traversed by ordinary practice, upon a drum 19, actuated by suitable gearing anda crank 2l, said drill-rope after leaving the drum first passing over the pulley 17 at the axis of the lever 16, and thence passing to the pulley 18, and'nally to the tools. In the drawings I have shown drill-tools 22 of the tubular type, from the upper end of which extends a conductor 23 for the slush to be deposited in a suitable trough 24; but it will be understood that tools of the solid type may be used with the mechanism embodying my invention. An ordinary operating handle or lever 25 is secured by a clamp to the shank of the tool which is illustrated.

Secured to the derrick-ladder near its lower end and preferably abovethe plane of the drum 19 is a cross-bar 26, connected by counterbalancingfsprin gs 27. with a movable or reciprocatory cross bar or head 28, and said cross bar or head 28 in turn is connected by a rod or cable 29 with that arm of the walking-beam or rocking leverwhich is remote from the guide-pulley 18, a pin 30 being used as the means of connection ofthe upper end of said rod with the lever and being adapted for engagement with either of a plurality of transverse openings 3l, formed in said lever at dierent distances from its fulcrum. Obviously the tension of the counterbalancingsprings 27 is opposed to the depression of the pulley-carrying arm of the rocking lever; but by engaging the pin 30 with openings 31 at different distances froln thefulcrum ofthe lever the apparatus may be adapted to `counterbalance .tools of different weights, said pin being engaged with an opening near the 'fulcrum of the lever when light tools are to be used and being engaged with. more remote openings when heavier tools are to be operated.

In operation the tools are lowered to the desired point by the paying out of the drillrope from the drum 19, after which the drilltools are reciprocated by the `periodic manual depression thereof through downward pressure applied tothe handle or lever 25, and as the hole becomes deepened thefdrillrope is still further unreeled, as in the ordinary practice. The counterbalancing-sprin gs 27, of which two are shown in the drawings,

but of which any desired number may be em-` depression, andthus relieve the operators of 4 the effort lnecessary to raise the tools.

- It willjalso, of course, be understood that,

' when desired, a drive-weight or crushing-bar i p .direction to be grasped by the operatorrfor remay be employed in connection Vwith thedrillf` rope, the drillingtools being removed vandV the weight or bar substituted therefor, these 1 substituted parts beingxgiven the, same mo-V` tion as `the drilling-tools; also, the windingl drum may bevomitted'and the rope otherwise held. Furthermore, instead of moving the pin backwardly and forwardly in the holes in the walking-beam the same result may be secured by varying thenumber yandtension of the springs. l y
