Be it known that I, THOMAS W. HOLLEY, a citizen of the United States, residin at Ranger, in the countyof- Eastland and state of Texas, have invented certain new and useful Improvements in Pedestals for Sand- Reel Shafts, of which the following, is a specification.

The present invention relates to bearings and more particularly to pedestal bearings for the tail end of sand reel shafts.

It is now common practice to support the shaft of sand reels at one end by a wooden tail post framed to a sand reel tail sill which is in turn supported on mud sills of the well drilling rigs. The tail post is usually of oak and has a hole bored transversely into its side constituting a bearing for the sand reel shaft. As a result the wood wears away the hole becoming enlarged so that there is considerable obj ectional play and which ultimately necessitates the replacement of the post or the provision of a bushing or some filler about to split since the bringing of the sand reel into use subjects the post to considerable stresses and strains incident 'to raising of the bailer and forcing of the sandreel pulley into such frictional engagement withband wheel as to function properly. Furthermore, with this type of tail post, it is not always possible to erectjthe'rig 'and dispose the post so that it is in proper, relat on to the band wheel that there will be good intinmate contact between the band wheel and pulley and much time and labor may be consumed in adjusting parts so that the sand reel pulley will not unduly wear the band wheel. a

One of the principal objects of my invention is to provide a pedestal for sand reel shafts which may include the usual tail sill, mud sills and a modified tail post,'adapted to carry a bearing which may be readily adjusted vertically and longitudinally of the rig and held firm in the adjusted position against accidental displacement incident to use of the rig. In this connection it has been found that vibration andforces coming upon the rig is apt to cause displacement of the ordinary sand reel tail sill and'tailpost and. consequently adjustments must be made if sand reel shaft.

the efficiency of the apparatus is to be tained at av maximum. j Another object of the invention is to provide a pedestalfor said reel shafts in which a metallic bearing block isprovided adapted to receive an alloy lining such as Babbitt metal, since this hearing must serve as a pivot for the tail end ofthe sandreel shaft. This lining may be. readily replaced or remelted and used. again, when necessary to provide asubstantial bearing.

Other objectsyand advantages ofthe in ventlon will appear'in the following detailed description taken in connection with the accompanying drawings, forming a part of this specification, in which drawings:

In the drawings, where asin'iilar characters refer to similar parts throughout the views,

in elevation show- 6 is a fragmentary detail sectional A designates the sand reel end portion of well drilling rig, including main sills B, mud I sills C, sand reel D having 'a shaftjl l and pulley F, hand wheel G and pedestals H and J for shaft E. v v

The 1nvent1on. is herein shown {as applied to what is commonly known asthe standard.

rig, in which the sand reel shaft E is disposed with its axis extending diagonally cross wisethe longitudinal 3X18 ofthe base of the rig, but it is to be understoodthat the.

principle of this invention maybe applied. other types of rig, withoutdeparting from the spirit of the invention; It is understood that, in practice,'the sand reel D is used for the purpose of lowering and raising a sand pump or bailer, not shown in the drawings,

and this isaccomplished by moving the shaft t, as by shifting the bearing 8 of pedestal H so that the pulley F is moved into and out of engagement with the band wheel G. i

The particular type of pedestal H shown in Figure l of the drawing does'not form'a part of the present invention, but is more specifically disclosed in my co-pending application for patent filed on the tenth day of February, 1921, Serial Number 444 030, It is shown merely by way of eXample'to indicate that the bearing 8 maybe shifted longitudinally of one ofthe main sills B, as by mechanism 9 so that the pedestal J embodies the pivotal bearing for shaft in, ashereinafter noted. The present invention is desig natedby character J. i

The pedestal J, in addition to the mud sills C, in the example shown, comprises a tail sill 10, tail post-11, bearing block 12, means 13 for adjusting the bearing block longitudinally of post 11, means 1d for securing the bearing block 12 to the post 11 in adjusted position, and means 15 bracing the block 12 fromthe mud s lls (l.

As is the usual practice, the mud sills (J are shown in spacedapart relation, and the tail sill 10. may be of ordinary formation, supported by these mud sills in adjusted relation, as by wedges l6.

' The tail post 11 may be carried by tail sill 10 in the usual manner, that is, by having its lower portion dove tailed as at 17, received in a recess. 18 in the sill, a wedge 19 being provided to hold it in fixed relation i to the sill. It. ispreferred to-provide this post with a seat 20 and an'upright abutment 21 laterally of said seat and this may well be accomplished byreducingtheupper end port on or the tail post, asiclearly shown in are 4 of the drawings. I

.rieferring now to the bearing block 12, it is preferably made of metal, and is provided with a shaft receiving openingQQ, prefer ably lined with Babbitt metal 23, this op'ening receiving the end portion ofthe sand reel shaft E. In the preferred emboi ilinlent of the invention, and for a purpose to be subsequently set forth, this bearlng block is,

also, provided with transverse ways 24, vertical ways25 and recesses 26 open at each end of the block and intersecting the axes of ways 25 The ways 24: are arranged in pairs one pair. being above the opening 22-and the other pair therebelow. are provided 'a djacentthe ends of the block, one at each side of the opening 22., The

The vertical ways 25 block 'lQis adapted to be supported by the seat 20 of the post, asjby resting directly thereupon, or when adjustment is, desired vertically, there may be interposed bet-ween I the block and the seat. filler pieces 27. The

bloclr'is also adapted to engage the abutment the 2L and when in use is held firmly against this abutment and in supported relation to the seat 20.

As suitable means for adjusting the block longitudinally of the post 11, the means 13 is provided and comprises vertical rods 28, one each side of the post 11 and nuts '29, 30, 31' and 32- in screw threaded engagement with these rods for the purpose of holding them in fixed adjusted relation with respect position with respect to block 12,;while nuts 32 engage the under side of the sill; 10. It is thus to be noted that, by releasing either nuts 31 or 32 and rotating either nuts 29 or 30, the block 12 may be raised with respect to seat 20 and after in the desired. adjusted position, the nuts which have been released may be tightened, thus holding the block firm in adjusted'positi'on towardjor from sill 10, and n a manner to be securely supported by the seat 20.

After the block h'asbeen adjusted in a. vertical direction, it may be secured to the bearing block 12, as by meansld, which, in the example shown, comprises a pair of U-shaped members '33 which .embrace the post 11, the stems 34 of these members 38 extending through the transverseways 24in the bear-i ing block, and provided with nuts 35 in screw threaded engagement with the end;

portions of stemsBeh-c t j The bearings for the shaft of sand reels are sub ected tostres'ses andstrains incident to lowering and raising the sand pump or bailer and the greatest pull upon the shaft is usually upwardly and diag'onally, in the line ofdlrection of the cable leading offfrom brought upon the bearin [incident to bringsand reel; There [is pressure.

Ulg Of lJhG pulley F into intimate contact with the band wheel G for the transmission of mot1on. There is also a slight. torsional stress at the bearing which acts asapivot for the ,shait, in moving the pulley F into engagement with band wheel G1 but thislis mayremain rigid even. wh n subjected to,

these forces, and-also to prevent longitudinal movementfof the tail {sill with respect to the mud sills. Suit-able means for this purpose is designated generallyby the character 1;?

and in the example shownis in the form of two tens oning devices 36, one for each end taken up, to a large extent, byflthe Babbitt of the bearing block 12. Each tensioning device comprises a rod 37, having an eye 38 adapted to fitin the recess 26 in bearing block 12 and to receive the vertical rod 28,.

as clearly shownin Figure (5 of the drawings; a turnbuckle 39 in screw threaded-engagement with rod 37 at its end portion with the bearing block 12, as by engagement of its eye 38 with the vertical rods 28; the turnbuckle 36 provides for minute adjustment of the tensioning device; and the chain 41 and the hook 42, provides for major adjustments. When erecting the rig, if it is necessary to move the tail sill 10' transversely of the mud sills C as by releasing the wedges 16, in order that the pulley F may be disposed in proper relation to the band wheel G, for successful operation, the hooks 42 may be disengaged from the links of chains 41 and after proper adjustment is had, the hooks may be disposed in operative relation to the links of the chains which are most suited for their reception, and the turnbuckles 36 may then be rotated to draw the eye bolts and rods 37 of each tensioning device toward each other.
