To aZZ whom it may concern:

Be it known that I, JOHN A. MoDoNaw, a citizen of the United States residing at Clarksbur in the count of I-Iarrison and State of l est Vir inia, ave'invented certain new and usefu Improvements in Sand- Recls for Well-Drilling Rigs, of which the following is a specification.

My invention relates to well drilling apparatus and particularly to a short` iron sand reel therefor adapted to be used with a standard rig such as ordinarily provided for drilling oil gas or Artesian wells.

One object of my invention is to provide a short sand reel made of iron, capable of doing the work required of a sand reel in an easv manner and not requiring any changes to be made in the general construction of any ordinary and standard rig.

A further object is to rovide a sand reel in which all of the objectionable features incident to the present sand reels in use are eliminated, such sand reel bein of very simple construction, substantially made and easily operated, the parts being made in dii licate so that in case of any part being estroyed another part of the same character can be easily and conveniently placed inlposition, the reel being so constructed that all parte are easily accessible. y i l My invention is shown in the accompanyin drawin wherein,

i`igure 1 is a plan view of a standard rig showing my improvements in (place thereon, the derrick, samson post an other arts not connected with my invention not ing shown. Fig. 2 is an elevation of a portion of the foundation for the rig and the band wheel, whereby power is communicated to the sand reel, the sand reel being shown in elevation at brake partially in section. Fig. .'3 is a pers ective view disassemblcdof the inverte sand reel lever and bearing therefor. Fig. 4 isa fragmentary sectional view of one end of the sandyreel showing the manner of holdingy the gudgeon in place. Fig. 5 is a diams ri of the friction wheel wherebv power i's transmitted to the sand reel. Fig. 6 is an enlarged fragmentary,elevation4 of a ortion of the friction wheel. Fig. 7 is a ace view of one of the flanges of the rcel, and Fig. 8 is a dpers ective view. of one section of the mid le ange. l

Referring nowfparticularly to .A Figs.- 1

cal sectional view and 2 2 designates the main sill and 3 the subsill of a well drilling rig. 4 designating the transverse mud sills usually used .for supportingthe main sill and subsill, 5

designating the front jack post, and 6 the rearfack post. Mounted upon the jack posts ist-he usual band wheel 7 constructed in any desired manner and mounted u )on n. transverse shaft 8 which is supported1 in bearings in the jack posts 5 and 0. This band wheel 7 is usually about 10 or 11 feetl in diameter. Also mounted upon the shaft. 8 and moving with the band wheel 7 is the tug rope wheel 9 which is about 7 feet in diameter. The shaft 8 is provided at its end with a crank 10 of any usual construction whereby power is communicated to n walking beam 7. These parts are all old and may be constructed in any desired inanner. In order to secure suilicicnt friction, between the band wheel and the friction wheel on the sand reel, the circumference of the band wheel 7 is rovided with lagging strips 7, thus a Ording a wooden periphery so as to secure good frictional contact etween the band wheel and the sand reel.

The sand rcel drum is com osed of an iron pi e 11 about 11 inches in diameter. Thel en s-of this ipe ure provided with dgeons 12 having the peculiar forni s vOwnin Fig. 4. The base of the gudgeon is outwardly flared as at. 13 and the margin then -returned upon itself toward the end of the gudgeon so as to rovide a flan e14whicli tits snugly witiin the end o the pipe 11 and which may be attached to the pipe in any desired manner, preferably by the bolts 15. One of these dgeons is provided at each end of the rum 11. Mounted upon the tubular druni 11 are 3 flanges, designated 1G, 1T and 1S. These flanges are constructed as shown in Fig. 7 and are preferably made of two sections, having the radial flanges 19 at the ends of the sections. These two seetions are adapted to be clamped by bolts 2O to the drum and are provided on their exterior faces with the radial ribs 21 extending out from the hub 22. It will be seen that flanges constructed in this manner. ma be easily removed from the drinn and rep nocd thereon and that the flanges may be easily shifted when desired.

The middle flange 17 divides the drinn into two sections or spools, one of them,

lili) lll',

that onecontinu'ous-wire isused, the werkmg portion of which is .wrapped upon'the working spool whilethe rremainder of the wire'is assed through the se ental openmg an wrap ed upon the rum between the ribs lan 17.

One end of the drum is provided with a friction wheel 35, shown in Figs. and 6. This friction wheel comprises the oppositely Idis osed sectionalend'pieces 24 and periphera laggingO. Theend leces each consist'o'f two sections 24' and 4bhavng end radial tianges whereby the sections are adapted to be clamped to'each other and around the drum 11.- These end ieces of the friction wheel are about 88 inc les in diameter and have an internal diameter slightly larger than the external diameter of the drum. The inner face of each of the sections is provided with radial ribs 26 and the circumference of each of the ends is formed with the circumferential recess 27, this recess being undercut. The sections 24* and 24"'are held together b bolts 28 which are d1s osed close to the ub of the friction whce and by bolts 29 which are disposed near to the circumference of the wheel. Mounted between the ends 24 and spacing them a art are the lagging strips 30. rlhese are pre erably of maple and lhave beveled ends 31 which fit in the recess 27. The end pieces of the friction wheel are held in en agement with the ends of the lagging an 1n rigid relation to eachother by transversely extendin bolts 82: which pass through the ends o the sections and are eachl provided with a head on onev` end and a nut upon the other. All bolt holes on one of the end ieceshave a s' uare recess" 83 in which the ead of .the bot is 'received and the other end iece has a smooth surface against which e nut on bolt 82 bears. A friction wheeliconstructed 'in accordance with this descri tionfI havelfound to be very durable. he I; construction of the wheel permits the lagging to be replaced at any time, and also permits 'the friction wheel to be shifted along the drum so as tol easily adjust it 'to its roper position or to permit it to be ref nove .n

While one friction wheel can be"used for transmittin ypowerfrom the bandwheel tothe san reel andggl'also ,for braking fthe sand reel, I preferably provide-two friction wheels 85 and', asshown'in Fig. 1.'l 'One of these friction wheelsjc'ontacts with-the band wheel 7 whilethe 'other engages the brake band 37 as shown in Fig. 2. yThis brake band is about 10 inches in width and Fig. 8.

Y l t is attached at one end to any suitable supand -18, -formmgthefworkingspool,wh1le jthat portion between` the'nanges 16.* a'ndfy17 j forms the spoolfor the "reservel ori-fsurplus prtggand atlitsother endto a transverse eam""38. It will be 'seen that when the ysand.reelisf-rnoved toward the band wheel the :friction drum 35 will contact with the rband wheel and thus the power will be transmitted to the sand reel.

l 1 `When, however, the drum is moved in an opposite direction and away from the band w ieel 7 the friction wheel 36 will contact with the brake band 87 and the motion of the sand reel will be checked.

For the purpose of moving the sund reel to bring the friction wheels and 36 into contact with the band wheel and brake band res ectively, I mount the gudgeon 12 at one en Iof the Sand reel in a bearing 40, this bearing being shown in detail in Fig. 8, andthe gudgeon located at the other end ofthe'sand reel is mounted in bearings in aninverted lever 50.l The bearing 40 for the relatively7 fixed end of the sand reel, as Shown in Fig. 3, comprises a plate 4l, the upper end of which is recessed at Ll2 and provides part of a journal bearing tor the gudgeon, a cap 43 rests upon the end of the plate 41 and forms the other half of the tournal bearing for the gudgeon. It is to e understood that the gudgeon 12 which rotates within the bearmg 42 is slightly smaller than said bearing so as to permit of "lateral movement of the drum. The cap 48 is held upon the member 4l by means 0f the bolts 44. The plate 41 at its upper end is laterali enlarged as at 45 so as to form a shoul er fitting over the post 46 upon which the journal bearing is sul ported. The plate 41 is held to the post 46 means ofthe bolts 47 or in any other suit- 'a le manner. The opposite end of the sand reel and drum 11 is supported by means ot thejgudgeon 12 in a bearing formed in un inverted lever'O, illustrated in detail in This lever 50 is oilset at one end as at'51 so' as to form a shoulder 52 upon which the cap 53 is mounted, the face of the Shoulder 52 being also formed with one halt of the ournal bearing 54. The offset end 51 of t e lever 50 is formed with a thickened head 55 through which passes a pivot. E1n 56 which projects from a bearing plate 7 y,mounted upon the post 58.- This bearing plate 57 is' shouldered as at 59 to fit over the post, the face of 'the plate being formed with the'recess 61 into which the heads ot the bolts 62 which hold the plate to the posts are received. The downwardly extending endof the lever is connected by connecting rod 63 to a hand lever whereby ttn'ay be actuated. The connecting rod (323 gasses beneath the tug rope wheel t) and is isposed between the longitudinally extending sills 2'and 3 so as to be entirely ont of the way. This connecting rod 63 moves preferably in guides 64 which are attached to the belt house floor. At its rear end the connecting rod 63 extends back to the usual platform 65 and is pivotally connected to the arm 66 and connected to a rock shaft 67, this shaft being connected at its end to lever 68. It will be seen that by operating the lever in one direction the rock shaft 67 will be turned thus moving rod 63, throwing over the lever 50. The lever, turning upon the pivot 56, carries the adjacent end of the sand reel outward and thus carries the friction wheel 35 away from the band wheel 7 and friction Wheel 36 into Contact with the brake band 37. A reverse movement of the lever 68 will shift the lower end of lever 50 toward the band wheel 7 thus mov ing the friction wheel 36 out of contact with the brake band 37 and moving friction wheel 35 into contact with the band wheel 7. By this arran ement the friction wheel 35 is prevented rom being worn smooth by contact with the brake band 37 and thus a better frictional engagement is secured between the friction wheel,7 and the friction wheel 35 than if the brake band turned upon the friction wheel 35.

The bull ropes which pass over the tug Wheel and extend to bull wheels (not shown) in the'rear of the derrick are designated 69.

It will, of course, be understood that I have not shown a large part of the mechanism of the rig inasmuch as this mechanism is not a partof my invention and is such as is commonlwi7 in use.

Preferably the bearings for the gudgeons formed in the journal 4l and in the inverted lever 50 are lined with Babbitt or other metal which wouldv give a satisfactory and serviceable bearing. Heretofore sand reels have been mounted in wooden bearings and have not been at all satisfactory.

It will be seen that the sand reel is made entirely of iron with the exception of the face of the friction wheel which is made of the transversely extending lagging strips 30. It is not practical to make the face of the'friction wheel of iron as it. does not produce the desired amount of friction be tween the band wheel and the friction wheel.

The shaft or drum ll, as illustrated in the drawing, has a thickness of if inches and is about ll inches inside diameter which gives a correct size for spooling the line in use and has a greater strength and durability7 than the shafts ordinarily used for sand reels. l

It will be seen that the gudgeons being i removable may be easily replaced when l worn without destroying the body of the drum and that the drum or shaft ll may be made of ordinary pipe such as is easilyi procurable.

It will be seen that the peculiar form of

flanges

16, 17 and 1S, illustrated in detail in Fig. 7 provides a flange made in two sections and bolted together so as to 'permit itto be clamped on the drum thus eliminating the use of keys or set screws. The flange 16 will have a hole drilled through it at 16a for the purpose of clamping the end of the rope to a rib of the flange to hold the rope in position when about to spool the rope on the sand reel preparatory to using.

A sand reel constructed in accordance with my invention is of minimum length and yet of such construction that it will do the work successfully and properly at any depth of drilling. The sand reel should be set with its axis about 6 feet 3 inches from the axis of the shaft for the band wheel shaft. Such position will bring the spooling in perfect alinement with the usual sheave carried at the top of the derrick.

An importantadvantage of my sand reel is that it only extends a relatively short distance over the sill 2 and therefore does not form an obstruct-ion at the point where the casing and tubing for the well have to be handled. In the ordinary rig the iron sand reel is a foot longer than the sand reel shown in my construction and very greatly obstructs done at this point.

The inverted sand reel lever 50 being of iron, cast or otherwise formed, having a babbitted bearing insures a smooth. running of the sand reel and provides a bearing which will permit the machine to be used for several wells.

The improved lever is very much superior to the clumsy swing lever and knuckle post heretofore in use, particularly because of the fact that at the point where the lever located room is quite an object and furthermore because it permits the connecting rod to be located below the sand reel instead of above the same and thus carries the con necting rod out of a position where it would interfere with the movement of the bull the work necessary1 to be' ropes. The connecting rod passes under the tug wheel and in this way does not interf ere with any other part of the standard rig.

Having thus described the invention. what is claimed as new is In a well drilling rig, spaced posts of unequal height, a bearing plate seated against the inner face of the taller post and having an offset shoulder at its upper end seating upon the top of the post, the face of the plate being recessed to form a marginal rib having a smooth bearing face lying in a vertical plane, bolts passed through the plate and post to secure the plate in place, the heads of the bolts seating in the recess of the plate, a pivot fitted in the bearing, a lever hung from said pivot and bearing closely against the smooth bearingface. of the rib `of the p1ate',the1ower its other end in the bearing on the shorter 10 free end portion of the lever -being offset to post, g l provide a transverse shoulder spaced below 'In testimony whereof, I a'ix my s'gnaand extendinglsliwz from lhe pl'vot, a bear ture in presence of two witnesses.
