UNITED STATES PATENT OFFICE.
MORTON G. BUNNELL, OF CHICAGO, ILLINOIS, ASSIGNOR TO FREDERICK C. AUSTIN, OF SAME PLACE.
WELL-MAKING MACHINE.
SPECIFICATION forming part of Letters Patent No. 560,120, dated May 12, 1896.
Application filed March 17, 1896. Serial No. 583,586. (No model.)
To aZZ whom it may concern.-
Be it known that I, MORTON G. BUNNELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in ell-Making Machines, of which the following is a specification.
My invention relates to improvements in that class of well-making machines which are designed to give an up-and-down or churning motion to the drilling-tools, and the objects of my invention are to provide simple and eficient means for giving the drilling motion, for varying the length of the drop of the drill, as required, and other features of improvement more particularly described in this specification. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a front elevation of the machine embracing my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged detail of part of Fig. 1, showing in front view the drilling-sheave, the crank-arm, and the actuating-counterweight. Fig. 4 is an enlarged detail of part of Fig. 2, showing in side view the drilling-sheave, the crank-arm, and the actuating-counterweight.
Similar letters refer to similar parts throughout the several views.
The frame of the machine may be of any suitable form; but I prefer to utilize the lower part of the two derrick-legs A A as the frame upon which to mount the principal parts of the machine. The derrick maybe of any suitable form.
B is the main shaft, working in the j ournalboxes C, which are attached to the frame A.
D is a driving-pulley.
E is a spool or drum mounted loosely on the shaft 13, upon which the drilling-cable e is wound.
F is a brake-wheel on the drum E, and f the brake-band, and f the brake-lever for operating the brake.
f is a spring for holding the lever f from flying up when released.
G is a ratchet-wheel on the end of the drum E, and g the pawl for engaging with. the ratchet-wheel.
H is a clutch of any desired form,so arranged that when its two jaws are brought into engagement the drum E revolves with the shaft B.
I is a gear mounted loosely on the shaft B, which can be made to revolve with the shaft B by the engagement of the two jaws of the clutch i.
I is a gear securely attached to the shaft J and meshing with the gear I.
K are the brackets carrying the journalboxes j of the shaft J.
L is an actuating-counterweight securely mounted on the shaft J, having the projection Z for engagement with the crank-arm M.
'm is a j ournal-box loosely fitting the shaft J and arranged to slide in the slot m of the crank-arm M.
m is an adj usting-screw swi'velly connected with the journal-box on, so that the position of the journal-box m in the slot m of the crank-arm M is determined by the screw m the position of the journal-box m regulating the length of the crank-arm M from the center of the shaft J.
'n is a wrist-pin atthe end of the crank-arm M. On the wrist-pin n is loosely mounted the sheave-pulley N, (herein called the drillingsheave) The operation of my machine is as follows: The drill-cable e having been wound on the drum E, the free end passes around the drilling-sheave N and around the crown-pulley in the top of the derrick and is attached to the drilling-tools in the ordinary manner, so that the drilling-tools hang suspended. Shaft B having been put in motion by any suitable power and the jaws of the clutch 2' having been brought into engagement, the shaft J will revolve, by means of the gears I and I, and with it the actuating-counterweight L, and the projection Z will come in contact with the crank-arm M and carry it around, and with it the drilling-sheave N, which will depress the drill-cable e and raise the drilling-tools; but when the drilling-sheave has reached its lowest point the tools will fall by gravity and the drilling-sheave with the crank-arm fiy around until they reach the point of rest and will remain there until the projection Z of the actnetting-counterweight L again carries them around, and the repetition of this gives the up-and-down or drilling motion to the drill. The counterweight L is so positioned in respect to the projection 1' that the counterweight is ascending at the same time that the drilling sheave is ascending, and 'conse quently as the tools are dropping the length of the drop of the drilling-tools is regulated by the length of the crank-arm M, which is controlled by the screw m When it is required to raise the drillingtools, the jaws of the clutch H are brought into 1 engagement. When the tools have reached the point desired, the jaws of the clutch H are released and the pawl g made to engage with the ratchet-wheel G. When it is desired to lower the drilling-tools, the pawl g is raised and the tools allowed to fall by gravity, thespeed of their descent being regulated by; brake-band f, operated by the lever f.
XVhat I claim as my invention, and desire I substantially as described.
to secure by Letters Patent, is v 1. 'In a well-making machine, the combination of an actuating-counterweight and a: crank-arm whose length can be adjusted, said crank-arm carrying a drilling-sheave substantially as set forth.
2. In a well-maklng machine, the combination of an actuating-counterweight, a crank arm with an adjustable box, said crank-arm carrying a drilling-sheave substantially as set forth.
3. In a'well-making machine, the combination of a revolving shaft, and a rigid actuating-counterweight thereon having a projection, a slotted crank-arm loosely embracing the shaft in the path of the projection of the weight, and a sheave carried by the crankarm for actuating the drill-cable, substantially as described.
4. In a well-making machine, the combination of a revolving shaft, and a rigid actuating-counterweight thereon having a projection at one side, a journal-box loosely fitting the shaft, a slotted crank-arm in the slot of which the box slides, means for adjusting the relative position of said arm and box, and a i sheave for the drill-cable, the same being held by a wrist-pin on the side of the crank-arm,
In witness whereof I hereto set myhand and seal this 12th day of March, A. D. 1896.
