This invention relates to well drilling apparatus, and comprehends a" structure mounted on the chassis of a motor operated vehicle, and designed to be quickly and conveniently arranged in position for use, and

operated from the traction wheels after the latter have been jacked or spaced from the ground.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and v arrangement of parts as claimed.

Figure 17 is a view taken at a right angle to Figure 15 and partly in section.

Referring to the drawing in detail A in-v dicates generally the running gear of a motor operated vehicle, wherein 10 repersents the traction wheels.

Rising from the frame of the running gear are spaced parallel standards 11 and 12, which are connected by the spaced parallel members 13, defining an auxiliary frame upon which the boom 14 is pivotally sup ported, this boom having associated therewith the reciprocating beam 15 which slides through a suitable bearing in the upper end of the boom. This boom normally lies in a horizontal position as shown in Figure 1, and is adapted to be swung to a vertical position at one end of the machine when its use is desired. The boom may be elevated and lowered in any suitable manner.

Journaled between the standards 11 is a drum 16 about which the cable 17 is adapted to be wound and unwound therefrom as the occasion may require. Also, pivoted be tween the standards 11 is a walking beam 18 including. the shaft 19 upon which is mounted a guidepulley 20, over which the cable 17 is trained as shown in Figure 1. An additional guide pulley 21 is supported adjacent the apex of the walking beam as shown in Figure 6, the cable17 being trained under the pulley 21, and then extended and trained over the pulley 22 carried by the upper end of the reciprocating beam 15. The well drilling tool (not shown) is ofcourse suspended from the free end of the cable 17, and incident to the operation of the walking beam 18, the said tool is raised and :lowered in the well as will be readily understood.

As shown in Figure 7 the reciprocating beam 15 is yieldably connected with the walking beam 18, to cushion the operation of the well drilling tool, and this connection includes a yoke 23 projecting from the lower end of the reciprocating beam 15 and provided with longitudinal SlOtS an eye belt slide through the clos 1 the yoke 23, the eye of said bolt being connected by a pin 26 with the adjacent extremities of links 27 depending from the adjacent end of the Walkin beam 18, the pin 26 sliding in the slots 24 a oy e mentioned. Threaded on the eye bolt 25 are nuts 28, between which and the closed end of the yoke 23 is arranged a cushioning spring 29, which encircles the bolt 25 as illustrated.

The walking beam itself is also yieldably connected with the frame of the Vehicle or machine to cushion the operation of said beam as clearly shown in- Figure For this purpose an inv'e'i'gt'ed U -sha ed' bracket- 30 is secured to the frame of the machine,

while slidable through the closed end of said bracket is i fed 31' the latter depending from a shaft same-lea; by the walking beam 18. A cushioning spring or other yiel dable element 33 encircles the rod 31 and interposed between} the" closed hd of the bracket uardians 34 carried by said r d" I While any suitable means] may be emplby'e'd far spew an whiting beam is, I preferably employ the mechanism clearly illustrated inll i'gures 1, 4e, and 5' respectively, wherein it will be noted that the heani 18' is actuated" from the rear wheels 10 of the: machine. These" wheels' are of couise operatedby the motive" power oi the ma chine and wi hen employed to operate the" beam 18, the machine is suitably' jiicltedj to miechanism includes cui vec'l bar 35 which is pi'vot'd as at Bhloii the outsi de oft thewheel', it of course being understood that both wheels are cohstructe'd' and equipped in the same manner. Each bari'i's provided with a plurality of spaced notches 37 adapted to singly receive the crank pin projecting," from a link- 39'which' is pivoted upon the wheel as at 4 0. Connectynp; the crank pin 38 with the adjacent end of the walking the bar is held against pivotal movement by a suitable cam lock 42 arranged upon the wheel. nwi-nbe noted upon insl'action of Figure 1, that when the l'ihh 39' is arranged in a true venieal position; cent-rall of the bar 35 the wheels" 10 may rotate without eife'cti'n'g' tliefa't allti-ng' beam 1 8 thus allow inn the machine to be moyed i roi'n pl ace to place when desired.

W'hen it is nec'ess'aiy' to lower the tool within the well, or to remove it therefrom, the drum. 1G is actuated to wind the cable 17 about the drum or unwind it therefrom as the occasion may require. For the purpose of operating this dru'ni' I el'nploy.

git-cored wheels 43, one for each of the truetion wi'ieels 1'('),4 and' which wheels 13 are bolted or otherwise suitably secured to the hralte drums for the wheels 10. Links -14 depend from the shaft 45 jeurnaled in the uprights 11', and jourmued between the lower ends of these links a shaft 46 upon which lnblililtekl' \t'he'els 17 of the coni'igun ion clearly shown iii Fi' me 2 to titwith'ih the gro(' \}'es'of the wheels 43', the wheels 4117 beihg" frictionally driven from the wheels 13 as will be" readilyundhisto'od. The wheels 17 o'l. course matte the shaft 46 which has" n'iountcil tbefon a' small toothed when 18 ove which and a largen toothed whelAQ carried by the shaft l'ziof the drain, an endless" chain 50 trained, so that the drum is rotated hem? the shaft {16. The wheels" 47 however areonl moved into operative asT-K soci" 31011 with ti e wheels 41 3 when it (1e sired to wind the cahle 17 about thefdi'iim 16 or unwind the cable therefrom, an'dcon scqu'ently the" wheels Mare movable with the links 41 toward' and away, from the" wl'ieels 4'3. connected to a rod 51 which in turn are (a-onynected with the aujaenfi end of a lever 52 pivoted at 53, t'he' other end of said lever For this purpose the links aref being connected to' a rod 54 which eklhds to a hand operated lever 55, by means of which the ihbi cin e t of thewhecls toward and away filoin t1 e friction wheel's can be conveniently coiitro'lledi A sa n d linereel 56 is also operated from the friction drive wheels 523', and can be adjusted toward and away" from the latter in' any suitable man ner.

The jacks for raising the rear wheel's jlirom the ground are indicated generally at 57 and are pivoted between links 58 which in turn are pivoted on ,the'side' members of the fiaine 1 of the vehicle. These links are 'piovided with eyes 59 adapted to be engaged by hoolts 60' to hold the links '58 l'olded against the sides of the name as shown in Figure 10," during which time the jacks are also folded beneath the frame 01 the vehicle, and hld in this pnsition by a yoke 61.- Manifestly by releasing-f the jacks iiomf the 'yohe 61, and sepuratihg the links from the hooks 60, the jack structure can bequiekl'y' and convenien'tly l'owere'il intoengagcment with the ground" and subsequently adjusted to elevate the wheels 10. Manifestly I haa'c devised a well drilling apparatus wh-i-cl can be conveniently moved from place to place by the motive power of the machine, and said motive power subse- I till walking beam 18 can also be quickly adjusted to vary the throw of said beam, while the power and speed of the apparatus can also be easily regulated. The apparatus can be quickly set up for use, and the desired results accomplished with a minimum of time and effort.

In Figures 11 to 14 inclusive I have il lustrated a modified construction of the means for operating the walking beam, and which means includes a crank arm which has associated therewith a curved bar 61. In this form of theinvention the curved bar is formed on the crank arm 60, the crank arm being connected with the walking beam in the same manner as in the preferred form of the invention, namely by a connecting rod 62. The curved bar is provided with spaced notches 63 along its outer edge and adapted to singly receive a locking pin 64: which is slidable through the wheel 65. This pin 64 is carried by a yieldably mounted disk 66 which normally holds the pin 64 out of the notches 63, and which disk is moved in the direction of the wheel to force the pin into engagement with a particular notch of said bar by the means clearly illustrated in Figures 13 and 1 1. This means includes a bell crank lever 67 operated from a remote point by a rod or cable 68, one branch of said lever having connected therewith a yoke 69 which has journaled therein a wheel 70. hen the cable 68 is actuated, the lever 67 is moved upon its pivot throwing the wheel 70 into engagement with the disk 66, and thereby forcing the pin 6-1 outwardly into engagement with a particular notch on the bar 63. l/Vhen the pin engages the innermost notch as shown in Figure 11 the crank is held in its neutral position; while Figure 12 illustrates how the crank can be shifted to different positions and held in said position by the pin 6 In Figures 15 to 17 inclusive I have shown another form of the invention, wherein use is made of a straight crank arm 71 which is loosely mounted on the shaft 72, and provided with a plurality of openings 73, whereby the connecting rod 74 of the walking beam can be adjusted along the length of the crank arm to vary the throw of the beam as will be readily understood. In connection with the crank arm 71 I employ a substantially U-shaped clutch member 75 which is normally arranged between the crank arm 71 and the whtel 76, the clutch member being supported by fingers 77 to slide through the wheel 76. These fingers 77 are connected with a spring pressed disk 78 in the same manner as the'pin 64 above mentioned, and which disk normally holds the U-shaped clutch member betweenthe wheel and the crank arm 71 as shown by dotted lines in Figure 16. Vihen it desired to use the crank arm for the purpose above mentioned, it is only necessary to pull' upon the cable 79 which throws the disk 78 in the direction of the wheel T6, thereby moving the U-shaped clutch member outwardly to a position where it can straddle the adjacent end of the crank 71 as shown in Figure 15.

lVhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apaarent, I desire to have it understood, that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.
