UNITED s'IEvEBULLUM ANL .WILa-.IAIxIot .MAXIELIL or Los ANVeLEs'IGLIFoRNIA...
Be it known that We,- STEVEUBLIM Aand WILLIAM O. MAXWELL, citizens of the United this invention arerz'zx:
First: a shock absorbing. device between@ States, residing Vat Los Angeles, vin the county of Los Angeles and State `of California, have invented new and useful Improvements in- Spudding Jacks, of which the following isa specification. r
Our objeet'v isto make` a spudding jack,.
andour invention consists ofthe novelieaitures herein shown, described and claimed. 'fr'The' .principali objects toV be..` attained by the Apoint at which the power Lis applied (band Wheel crank) andftheotherportions of the'rig and machinery. f It has been cus-V tomary'heretofore to'use, instead of aideviee oftlns nature,.a section of manila vor Wirecable', called a jerk line, which was connect-f ed With the band Wheel crank by` means cfa collar commonly known: as a spudding ring,"
and thence extending in one solid piece'to a connection with a spudding shoe ywhich was fitted to the .drilling cable. This jerk line device Wasanchored down to the rig foundation at the same point as the anchor connection shown in vthis application, except that for this purpose a section of cable IvasusedV instead otthexhoolrrod and eyeboltas specified herein. :So longas a maniladrilling cable was used yforspudding the Well. in or- A getting the hole started there were no serious objections'to the old-*jerk line method asthe manila drilling cable* allo-Wed. for suiicient Vspring or giveto'absorb a large :pai-tof the shoclrresulting from the drilling motion.-
.g However, manila` drilling cable-shave now gone outo general use in Well drilling work,
giving vWayto steel: Wire cablef which is much more rigidin its reaction fromca shock such as results from a drilling motion. This Y rigidity'and resultant shockv isvery severe on the mechanical construction of the drilling.- machinery generally, L and one otfthe principal objects of' ourI device is to take this shock from therig vby means of a shock absorbing spring. l .i v Second: the'wheel device 14C rolls or turns While in lContact with the drilling table,
which feature We claimto be an improv'e-` ment over the /spudding shoe `method .now

At the opposite'end of the bar 12 frolnthe pulley ,14 arms 27 and 28 are made to form abifurcated bearing, and the extension arm 29feXtends-'fointhe arni'28- and has a' hook" 30 upon its extreme end-gf The rod 311;.isf
mounted in the bifurcation between the arms 27i and 28V in line with the.' hook 30.* The anchor rod 32 has a bifurcatedbearing33iat itsY upper end to stratldle the arms4 27 and 28, and apivot pin34V is inserted through the bearing 33 i through the arms 27 andi 28 and through the rod 31. The" hook 30 swingsf downwardly fromf'theA rod 31v and will not pass upwardly beyond the rod; A' hookl 35 is formed at the lower end of the anchor rod 32. 'An eye bolt 36 isiast'ened inthe sill` 37,= and the hook 35 engages the eye ofthe Y,boltl 36 so as to limit the upward swing of the rods-'12 and 31;- An eyelbolt 38 is inserted tlirough'the post 39 and a hook 40- is connected to vtheeye bolt to swing upwardly andengage the hookl 30 when desire'd;V Y A Af crosshead 41 is 'mountedupon theop; posite end of the bar 31 from the joint, aI spring 42 is -rnountedupoi'ifthe bar 31 againstv theY cr`osshe'ad-41, a" second crosshead 43 is y slidinglymounted uponl theV bar 31 againstr the spring, and a U-shape'd yoke'havingla central portion 44- and side bars 45A and46 is mounted with thev side barsv 45 and 46 sliding. through the crosshead 41V andv ex tending through the crosshead 43 with nuts 47 and w48 upon the ends of' theside bars 45vand 46 `against the crosshead' 43.
.The tension ofl the spring 42 is eixertedi to pressa the cr'ossheads 41 and 43 apart.- The'circular central portion 44 engages the groovedroller 9, andthe tension upon the rope liand the tension of the spring 42i's" exerted to hold this cu-rvedf central portion 44 in the groove whenthe .bandwheel is' running. When the'- parts are moved to proper position the hook 40,1nay'be swung upwardly to'engage the hook.v 3l); tlien .the
wheel started thetension on'the'Y hook'40will' be released andthe hook 40 will fall; Con: tinued operation of the` band wheel will make a bend in the portion 11 of the rope at each revolutionr of the band wheelthereby raising the?l drill or spliddingtool andithen i the .rope will straighten and allow the tool tofall. YV i Tlie anclorod 32'hold`s t e bars'12'and 31 from; vibrating upanddown and makes a steady'pull on the bar 12' at a practically steady angle. The spring 42 serves as a shock" absorber and makes ia yielding com nection betweenithe crank pin 7 and the rope portion 11.
