4 Claims.-
The present invention relates to well drilling machines, and is particularly applicable to portable drills, although not limited thereto.
It is the principal purpose of this invention to provide a novel drill stem feed arrangement whereby a frame which has a chuck that grips the drill stem is adapted to be rotated from a suitable power drive, the frame being so mounted that it can be coupled to the drill stem and driven through a greater length of stroke than has heretofore been considered practical.
More particularly, it isthe purpose of the present-invention to provide in a drill of the character'described a supporting and guide frame having means whereby a drill chuck can be lifted with its driving mechanism by means of a power lift such as a hydraulic lift a distance which is substantially double the stroke of the lifting-piston. The invention contemplates the inclusion of a driving mechanism for rotating the chuck at any level.
The features and advantages of the invention will be apparent as the description proceeds in connection with the accompanying drawings, wherein a preferred form of the invention is shown. It is to be understood, however, that the drawings and description are illustrative only, and that they should not be taken as limiting the invention except insofar asit is limited by the claims.

Fig. 8 is a view similar to Fig. 6 showing a modified form of the invention, and
Fig. 9 is a sectional view taken on the line 9- 9 of Fig. 8.
Referring now to the drawings, in Fig. 1 the Well drilling machine is shown as mounted upon a truck II] which has an engine II that furnishes power for the drill. The truck has a framework consisting of uprights it and braces I3 for mounting the drill frame upon the truck. The drill framework itself comprises a base I4 having four posts l5, I6, l1 and ill fixed therein and projecting upwardly to a top frame l9 upon which 5 a pair of standards 2|] and ti provide bearings for a shaft 22 upon which a pulley Z3 is mounted. The posts l5, l6, ii and it may be hollow pipes. as shown by Fig. 3. The framework made up of the base M and the top it! and the posts l5, I6, I] and i8 is pivoted by means of a bracket 24 upon a bearing 25 which is carried by the uprights l2 and the braces l3 so-that the entire framework may be folded down over the truck,
as will be readily understood. For further bracl5 ing of the drill framework brackets 26 may be mounted upon the posts it and ii and connected by a shaft 21. to which a diagonal brace it is secured. The brace 28 is slidable in a bearing 29 supported by the body It of the truck and may 20 be locked in place after the drill frame is raised, as will be readily understood.
The drill framework includes, in addition to the base it and the top frame it, an upper frame 30 which is fixed to the four vertical posts it, 5 l6, l1 and i8, and a similar lower frame 3i is also fixed to the vertical posts. The base it has mounted thereon a hydraulic cylinder 32 which extends up through the frame it and is bolted in place between the frame ii and the base M by 30 four bolts 33. The cylinder 32 has a piston 34 therein (see Fig. 6). A piston rod 35 projects upwardly from the piston 3i and carries at its upper end a support it for two shafts ill and it. The shaft ill has two pulleys t9 and it journalled 35 thereon and the shaft it has two pulleys ll and t2 'journalled thereon.
In front of the posts l t and it two chuck frame guide posts it and it extend vertically from the base it to the upper frame till. A chuck frame it 0 is vertically slidable on the posts it and it. The
frame it: consists of lower cross frame it and two uprights Ml and it which are bored to receive the posts it andM. The uprights ll and. it have extensions 49 and 5t in the form of hollow rods.
The extensions 49 and M are joined at their upper ends by an upper cross frame it which is recessed at 52 to allow a drill stem E3 to pass.
The chuck frame it carries a housing M which includes chuck jaws 55 and 56 (see Fig. 5) and 59 and 60. The opposite ends of the cables 51 and 58 are fastened to the back side of the frame 3| by suitable couplings SI and 62, the frame 3I being provided with a flange 63 to which the couplings are secured in a suitable manner. The pulleys 39 and 42 have cables 64 and 65 riding in the grooves of the pulleys. The cables 64 and 65 are secured to the cross frame 5I by couplings 66 and 61. The opposite ends of the cables 64 and 65 are secured to a cross bar 68 by couplings 69 and 10. Cross bar 68'is suspended from the frame 30 by means of a rod II. 4
It will be noted that a polygonal shaft I2 is journalled in the upper frame 30 and extends into a housing I3 on the base I4. This polygonal shaft is the drive means for rotating the drill stem 53. The shaft I2 has a gear I4 keyed to the lower end thereof and mounted between two bearings I5 and I6 within the housing I3. Drive connection is made from the power shaft (not shown) of the engine II to a shaft ITwhich is provided with a suitable coupling I8 for connecting it with a shaft I9 that is also journalled in the housing T3. The shaft I9 has a gear 80 thereon which gear meshes with the gear 14 and is mounted between two bearings 8i and 82.
The housing 54 includes a portion 83 through which the shaft I2 extends. Around the shaft '72 and within the portion 83 there is a hub 84. The hub 84 has a round interior bore receiving the shaft I2, but is coupled to rotate with the shaft by means of a cap 85 that is fastened to a flange 86 on the hub 84 by suitable bolts 87. The hub 84 has a gear 88 fixed thereon. Suitable ball bearings 89 and 90 are provided within the housing 83 for the hub 84 and the gear 88. The
lower end of the hub 84 is provided with a reduced screw threaded portion 9I on which a nut 92 is threaded to hold the bearing 90 in place. The upper portion of the hub 84 has a shoulder at 93 which holds the inner ring of the upper bearing 89 in place. .The gear 88 meshes with a gear 94 that encircles the drill stem 53 and is fixed to a hub 95 in the housing 54. The hub 95 supports a housing 96 for the chuck jaws 55 and 56. The chuck jaw 56 is shown as a stationary jaw which is secured to the hub 95 by bolts 97 which also secure the chuck housing 96 in place. The chuck jaw 55 is adjustable within the housing 96 to cause it to grip the drill stem 53'. A set screw 98 in the housing 96 is used for adjusting the jaw55. The hub, 95 and the gear 94 are rotatably mounted in the housing 54 by upper and lower ball bearings 99 and I06. A nut Iti is screw threaded onto the hub 95 to hold the bearings in position thereon. The hub 95 is hollow and within the interior of the hub there is a cone-shaped guide block I02 which guides a drill stem 53 between the chuck jaws 55 and 56.
The housing 54 is, of course, secured to the cross frame 46, the portion 83 thereof being offset as shown best by Fig. 4, so as to be vertically aligned with the shaft i2. It is evident, therefore, that the shaft 12 can drive the drill stem 53 by means of the gears 88 and 94 at any level between the upper and lower limits of the shaft I2. In the operation of the drilling machine, the entire frame 45 is raised by turning a power fluid into the cylinder 32 below the piston 34. The power fluid may be obtained from a pump driven by the engine II and is fed to a four-way valve I84 (see Fig. 6) through a pipe I05. This valve directs the power fluid to a pipe I06 to elevate piston 34. When the piston 34 is to be lowered, the valve I04 is turned to a position where it connects the pump to a pipe I01 that leads to the cylinder 32 above piston 34. When the valve is in this position it connects the pipe I06 with a discharge pipe I08 that leads to a reservoir tank carried by the truck I0. The details of the control equipment for supplying and withdrawing the motive fluid from the cylinder 32 are, however, not in themselves novel and may be of any suitable construction. Therefore, the pump, the reservoir tank and the details of the valve I04 have not been added to the drawings.
When the piston 34 is raised, the rod 35 lifts. the pulleys 39 40, 4i and 42, and this in turn causes the cables 51 and 58 to lift the frame 45, and with it the entire chuck rotating mechanism included in the housing 54, a distance which is equal to twice the distance that the pulleys are raised. The cables 64 and 65, owing to their coupling with the frame 5| and the cross bar 68, also remain tight around their respective pulleys. It this manner the frame 45 can be raised from the position shown in Figs. 1 and 2. The drill stem 53, which has been lowered through the chuck jaws 55 and 56, is secured by the jaws 55 v and 56 so as to be rotated when the power is applied to the shaft I2.
In order to hold the drill stem 53 while the chuck jaws 55 and 56 are released and raised, the base I4 is provided with a cone-shaped opening I09 through which the drill stem extends. Two
half-round manually removable jaws III! and III are dropped into the cone-shaped opening I09 so as to grip the drill stem and hold it in place. After the drill stem has started and the first length of stem is down so that the chuck jaws are just above the frame I4, the drill stem is held in place by the half-round jaws I I0 and I I I, and a new length of drill stem is then threaded through the jaws 55 and 56 from above and coupled to the first length of drill stem by a, suitable coupling such as is shown at I I2 in Fig. 7. The piston rod 35 can then be raised to bring the chuck jaws 55 and 56 to their uppermost position where they are clamped upon the drill stem 53 and the rotation of the drill may then be continued until it is necessary to connect on a new length of drill stem.
In Figs. 8 and 9 there is shown a slightly modifled form of mechanism for raising the drill chuck frame. port 36, instead of having the pulleys thereon, has two gears H3 and II4 journalled thereon. These gears mesh at the back with two stationary racks H5 and H6 which are secured to the back posts I5 and II in spaced relation thereto. Similarly at the front, the gears H3 and H4 mesh with the vertically movable racks II! and H8 which are'fixed to the cross frame 45' that carries the drill chucks. The vertically movable racks Ill and H8 are slidable through suitable guide openings in the upper frame 30', as shown at H9 in Fig. 8.
Outside of the gears H3 and I I4 suitable plates I20 and I2I are fixed to the ends of shafts 31 and 38 that project from the support 36. These plates I20 and I2I carry guide members I22 which are interposed between the frame posts and the racks.
The operation of the modification is substantially identical with that of the preferred form of the invention. It will .be readily understood that In this form of the invention, the sup- 0 be lifted twice as fast as the piston rod 35 is lifted.
From the above description it is believed that the construction and operation of this device will be readily apparent to those skilled in this art. Having described my invention, what I claim as new and desire to secure by Letters Patent is:
