ASSIGNOR `TO FORT WORTH WELL OF FORT WORTH, TEXAS, A CORPORA- KNUCKLE JOINT FOR WIRE-LINE SHEAVE WHEELS.
Application filed November 4, 1921. Serial No. 512,823.
f To all 2li/wm z5 may concern.
cation.
Be it known. tlat 1, Hanms Plinn, a. citizen of the United States of America, residing at Fort Worth` in the count)v of Tarrant and State of Texas, yhave invented certain new and useful Improvements in Knuckle Joints for lire-Line Sheave AThee-ls. of which v.the following is a speciication.
My invention relates to improvements in well drilling machines and more 'particularly to certain safety devices and means for improving the operation; and the object is to provide a simple device for preventing the severe hammering that goeson during the` operation in such machines heretofore on the market and in operation and preventing the rapid wear of the parts affected. Another object is to provide adevice which will make the operation of well drilling ma chines less dangerous to the workmen who operate the machines.
Other objects and advantages will be fully explained in the following description andl the invention will be more particularly pointed out in the claims.
Reference is had to the accompanying drawings which form a part of this appli- Fig. l is a side elevation of thvewimproved device together with suflicient part of a. well drilling machinel to show the application of the improvement. Fig. 2 is a detail view illustrating the-construction of the improved device.
vSimilar characters of reference are used to indicate the same parts throughout the several views.
The drawings show .the spudding frame which actuates the cable'which carries the drilling tool. The actuating frame is pivotally mounted on a shaft 1..y This frame is provided with arms or beams 2 and 3 and a cross-beam 4 attached thereto. This frame is vibrated by means of the bull Wheel 5 which isrigid with the shaft 6. A crank 7 is rigid With shaft 6. There are two cranks 7 one of which is shown. The shaft 6 is connected to thebeams 8 by means of bearings t?. vThe cranks 7 are connected to the spuddmg frame' or beams 2 and 3 by,
are pivotally connected thence under the sheave wheel 17. passing over a sheave wheel or pulley 18 and then down to the drilling` tool (not shown). The sheave wheel 17 is connected tothe spudding frame beam 4 by means ofan eye-bolt 19 and link bars 2() which are 'pivotally ,jconnectcd to the shaft of pulleyeor sheave wheel 17 and pivotallyconnected to the eyebolt 19 by a pivot pin 21. The eye-bolt 19 operates through the spudd'ing beam 4 and a spiral spring 22 is mounted on the eyebolt 19 between the beam 4 and a washer 23 which is held Von the eye-bolt by a nut l24. The spring permits a yielding of the eye-bolt upwardly. The eye-bolt will be drawn back toy normal position after an operation by the spring 22.
The sheave wheel 17 and the link bars 20 form a knuckle joint with the eye-bolt 19. The Iobject of the knuckle joint :is to prevent the severe hammering of the eyebolt on the'spudding beam 4`and also to prevent slack in the cable 15. The head of the eye-bolt rests on the metal plate 14 and the beam is thus protected. In operation, the spudding frame is actuated by the bull wheel 5 througlilink bars or arms l0 and the cranks 7. When the free end of the spudding frame is drawn downwardly, the sheave wheel 17 will draw on the cable 15 and so raise the drilling tool. When the and pivotally'connected to The free end of the spudding frame swings up- Ward or downward and throws the spuddmg frame rin diferent positions as compared with the normal, considering lthe normal position to be parallel with the beams/8; the cable l5 will be actua-ted for operating the drilling tool.' Y
of bolts.
With the old construction when the sheave wheel' 17 was journaled in a clevis which was rigid with the bolt 19 and a stiff bolt was used, there was much side pulling and lashing. tearing up of beams, and breaking These troubles are avoided by using the knuckle joint. knuckle joint, the sheave wheel 17 'has the swinging movement caused by the vibrations of the spudding frame and, in addition, has a swinging movement permitted by the knuckle joint, relative to the beam 4, as
Vsuccessful drilling-and at the same time shown by dotted outlines. By such construction, the sheave wheel 17 will take up -the slack of the cable 15.01' prevent slack in th'iscable at idle points and will thus avoid the sudden severe and positive jerks and hammering ot the working partsLand yet leave the string of drilling tools free to 'make their sudden drop necessary for most protecting the drilling cabley from undue strain at certain points by taking up 'the By reason of the of the knuckle joint Will readily move back to positive working position.
What I claim, is,- i j 1. In a well drilling machine provided with a spudding frame, an eye-bolt in said frame yieldable upwardly, a wire line sheave wheel, andv a knuckle joint pivotally. connecting said sheave wheel to said-eye-bolt.
2. In a well drilling machine provided with a spudding frame including a crossbeam, an eye-bolt movable upwardly in said frame and held normally downwardly, a wire' line sheave wheel and a shaft for said wheel, and link bars pivotally connected to said shaft and to said eye-bolt.
3. In a well drillingmachine provided with a spudding frame including a crossbeam, an eye-bolt movable in said crossbeam, a spring normally holding the eye of said boltvdown on said beam, a wire line sheave wheel provided with a shaft, and link bars pivot'ally connected to said shaft and to said eye-bolt.
11. In a well drilling machine provided with a spudding trame including a crossbeain, an eye-bolt normally held with the .eye thereof resting on said beam but yield able upwardly, a wire line sheave wheel, and a knuckle joint vconnecting' said wheel to said eyebolt.
In testimony whereof, I set my hand, this 22nd day of October, 1921.
HARRIS e. PARE.
