REEL

Application led May 15,

This invention relates to a reel jack and more particularly to a jack'for the wire line spools,V employed in well drilling apparatus.

An important object of theinvention is to produce a device of this character which may be very readily and cheaply produced Y and which, at the same time, will havesufii cient strength to enable 'it to withstand the harsh treatment to which such devices are subjected.

A further object of the `invention is to provide a device which is adjustable, so that wire line spools of different sizes may be These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein l Figure 1 is a front elevation of a wire line spool jack constructed in accordance withmy invention showing a wireline spool in position thereon;

Figure 2 is a side elevation thereof;

Figure 3 is an enlarged section on the line 3--3 of Figure 2;

Figure 4 is a section on the line 4-4 of Figure 2. n

Referring now more particularly to the drawings, the numeral 10 generally desig` nates standards, two of which are provided to afford mountings for the opposite ends yof a shaft 11 from which the spool 12 is sup` ported. Each standard comprises a base 13 preferably formed from plank fromY the center of which projects upwardly a pair of channel irons 14 having the channels 15 thereof opposed. The adjacent faces of the ianges 16 of t-he channel irons are 'spaced apart a distance equal to the diameter of the shaft 11 which is to be employed. The lower ends of these channel irons are secured to the standard by means of angle brackets 17,

one angle of which is bolted to the bight 13 of the associated channel iron and the other angle of which is bolted to thebase 13. At opposite ends of the base, metallic sill plates 19 are provid-ed from which extend upward'- ly converging braces 20, the upper ends of which are bolted to the bights of the chan- JACK.

nels at 21. These braces are preferably formed from pieces of pipe, the ends 22 of which are flattened and bent at an angle to provide bolting faces.

The upper ends of the channel bars are capped by a short length'of channel bar 23,

the channel of which is of the same internal l width as the external width of the channel bars 14 and the flanges 24 of which are bolted to the flanges 16 of t-he channel bars 14. n This cap is provided with a central opening 25 for the passage of the stem 26 of an eye Vbolt 27, thev eye of which receives the shaft 11. Seated upon the upper surface of each cap in surrounding relation to the opening thereofv is a thrustvbearing 28 against the upper' surface of which bears the wing nut 29 having threaded engagement with the y ly departing from lthe spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.

I claim Awire line spool jack comprising a spool receiving shaft and standards for supporting the opposite ends of the shaft each comprising a base, a pair ofparallel channel irons arising from the base having their channels opposed and thefree edges of their flanges spaced apart a ldistance equal to the diameter of the'shaft, a cap vfor the upper end of the channel irons having van opening formed therein, an eye bolt having the eye thereof extending into the channels of the vchannel irons and the shank thereof directed through the yopening of said cap and a wing nut operatively engaged with theV cap and threaded upon the shank of theeye bolt.

Intestimony whereof I hereunto affix my signature.
