ADAM H. HERJDIVIAN, E FORT WORTH, TEXAS, ASSIGNOR TO FORT WORTH WEL 4a MACHINERY dz. SUPPLY 00., 013 FORT WQRTH, TEXAS, CDBPOEATIUN 0T5 WELL-DRILLING MACHINE.

' citizen of the United States of America, re

siding at Fort Worth, in the county of Tar rant and State of Texas, have invented certain new and useful Improvements in Well- Drilling Machines, of which the following is a specification.

My invention relates to well drilling machines and more particularly to improvements for simplifying the driving mechanism, and the object is to reduce the number of shafts and other parts of well drilling machines and to provide means by which the principal functions of the machine may all be accomplished from one main driving shaft and to provide means for positioning the main or bull wheel of the machine for accomplishing the difierent functions of the machine.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

' Reference is had to the accompanying drawings which form a part of this application.

Figure l is a perspective view of the machine. Fig. 2 is a plan view with some parts omitted and other parts shown in section for clearness of illustration. Fig. 3 is an end elevation of the machine, certain parts being broken for clearness in illustration. Fig. 4 is a detail view of the diderent clutches for engaging the bull wheel.

Similar characters of reference are used to indicate the same parts throughout the several views.

The drawings show a machine complete and all mechanism for driving the machine mounted on a single truck. The machine has a frame composed of beams 1 and 2 and end beams 3 and '5. all carried on a wheeled truck 4for transportation of the machine and for supporting the machine. The machineis provided with a motor 6 for driving all the operating mechanism. The machine is provided with a main driving shaft 7 and the main drive or bull wheel 8 is mounted loosely on the shaft 7 and is slidable or axially movable on the shaft7. The wheel 8 is driven by a pulley 9 on the shaft of the motor 6 by means of a belt 10. There are three positions Specification of Letters Fatent.

for the bull wheel. In the neutral position the wheel 8 runs loosely on the shaft 7 for driving a pulley, 11 which operates the sand line by driving the spool 12. The pulley 11 is driven by friction against the wheel 8 and is moved into and out of contact withothe wheel by a crank 18 and a lever 14.- and link bar 15. The spool 12 operates the sand line when thus geared to the bull wheel in the neutral position.

a The wheel 8 has a beveled clutch member 16 rigid with one side and a straight clutch member 17 rigid with the other side. operating the tool line a spool 18 is loosely mounted on the shaft 7 and provided with a clutch member 19 which is rigid therewith. The spool 18 is provided with a brake 20 and a brake lever 21. The hull wheel 8 is shifted into operative relation with the spool 18 by means of a yoke 22 and a lever 23 which is fulcrumed on the frame member 2 and pivotally connected to a link bar 24: which is pivotally connected to the yoke 22. The bull wheel 8 can thus be thrown into and out of operative relation with the spool 18 for drawing the tools out of the well. The spool 18 is provided with worm gearing for paying 0d" the tool line, consisting of a gear wheel 25 (which serves as part of the spool) and a pinion 25.

For operating the spudding beams 27, the bull wheel 8 is shifted by means of the lever 23 to bring clutch. member 17 into mesh.

with the clutch member 28 which is keyed rigidly on shaft 7. Cranks 29 are rigid with shaft 7 and are pivotally connected to pitman rods 30 which are pivotally connected to the spudding beams 27. The shaft 7 is driven only when operating the spudding beams for drilling purposes.

It will be observed that there are three positions for the bull wheel 8 and this bull wheel is shifted to any one of these desired by the lever 23. The wheel 8 is shifted to neutral position for operating the sand line, shifted into mesh with clutch member 19 for operating the tool line, and shifted into mesh with clutch member 28 for operating the spudding beams for drilling purposes. The other parts of the drilling mechanism need not be described since they are not parts of my invention. Various changes in the sizes, proportions, and arrangement, and

-l or construction of the parts or elements above described may be made Without departing from my invention.

' What I claim is,-

1. In a-well drilling machine provided with a wheeled truck, a shaft journal ed on said truck,'a bull wheel loosely mounted on said shaft, a motor mounted on said truck and provided with a pulley and a belt for driving said bull wheel, and means for positioning said bull wheel for operating the sand line, or the tool line, or the spudding beam of the machine at will.

2. In a well drilling machine provided with a frame and a wheeled truck therefor, said machine being provided with the usual sand line, tool line, and spudding beams, a shaft journaled on said frame, a bull wheel mounted loosely on said shaft, means for driving said bull wheel, and means for positionin said bull Wheel for operating said sanld lme, or tool lines, or spudding beams at wil 3. In a well drilling machine provided with a frame and a wheeled truck therefor, said machine being provided with the usual sand line, tool line, and spudding beams, a shaftjournaled on said frame, a bull wheel mounted loosely on said shaft, means for driving said bull wheel, and a lever ful-- with a frame and a wheeled trucktherefor,

said machine being provided with the usual sand line, tool line, and spudding beams, a shaft journaled on said frame, a bull wheel mounted loosely on said shaft, means for driving said bull wheel, said bull wheel being provided with clutch members, one on each side thereof, a spool for operating the tool line loosely mounted on said shaft and provided with a clutch member adapted to be engaged by the clutch on said bull wheel, a clutch rigidly attached to said shaft 011 the opposite side of said wheel from said spool, and a lever fulcrumed on said frame for shifting said wheel axially on said shaft to engage said spool clutch to operate the tool line, for shifting said wheel to engage said fixed clutch to operate the spudding beams, or for shifting said wheel to neutral position for operating the sand line.

In testimony whereof, I set my hand, this 12th day of October, 1917.

ADAM H. HERDMAN.
