' WELL RIGGING. i c

Application filed February This invention relates broadly to improvements in well rigging and has more vparticu larjreference to novel and simplifiedmeans for removing rods and tubing from wells.V

The primary object of the present invention is to provide a device of the nature stated which will noty only raise the rods or r tubing from within the well but which will also lower the samey and carry them exteriorly `of the derrick. 1 n Another object of t-he present invention 1s y to provide such a device which will save bot-l1 time and labor in the pulling of rods and.v

tubing from wells thereby increasing the production of the wells at a reduction inthe cost of operating.

Another object of the invention isfto pro-` videfsuch a device of the naturestated which" is extremely simple in its construction, strongystur'dy and durable; eflicient andreliable in its operation and well designed for the purposes for which it is intended.

- Numerous other objects and advantages of the present invention willv become more readily apparent during the course of thefollowing description when 'taken in connection with the accompanying drawings:

In the drawings, forming a part of this y:application and `wherein for' therlpurpose of Figuregris a sectional view-on line 5--5 vfof Figure 1. y y g y Reference now being hadmore 'particularly' to the accompanying drawings wherein similar Icharacters of reference denote' cor` responding parts throughout the several views, it will .be Iclearly-seen that in carrying provided la plurality of sup orting blocks 9 carrylng vat their upper en s the transverse e sills 1'0 supporting the elongated horizontally disposed platform l1 one end portion thereofv being ytransversely enlarged as indicated at the present invention into'practice, there are v 12, 1926. serial no. y873964.`

12 and; rising from this enlarged end portion 12 isa derrick designated as a whole lbythe numeral13. -y l Secured to the top' 14of the derrick'l are the spaced bearing blocks 15, 16 'and 17 within which are journaled' the horizontal shafts or rods 18 and 19 on which are mounted the pulleys 2O and 21 respectively, these pulleys being positioned directly above openings 22 and 23 formed in the saidtop 14 of the derrick;` f

Carried byv the enlarged end portion 12 oft-he platform 11 immediatelya'djacent the outer end thereof, are thespaced yvertically disposed bearingl blocks 24 and 25 and ex i tending between Y, and secured `within these bearlng blocks is the rod or shaft 26' on which is rotatably mounted the reel designated kgenerally by the numeral 27', said reel being dividedinto sectionsI 28, V29;.a1nd 30 by the radiating spokes 31, 32 and 33 or .by means of-any suit-able guard pla-tes.y Carried by one'lendy of thereel 27 is a drive pulley or trained a drive'belt or chain '35.1having connection with fa `Suitable.driving engine, not

shown.' l

` Woundy aroundv the section `28o-of theineel 27 is one end ofthe cable 36, ,saidcabglepass---l .ing .upwardly throughthe top 14 of the derrick and over the ,pulleyf20 supportedthere# by. Secured'ftothe free end, ofthe vcable is a clamping member 37, said clampingmemvloer comprising'a tubularysleeve 38 and lpivroted to the upper edge of the said sleeve,intermediate their ends, are the oppositely po-A sitioned gripping jaws39 having pivoted to their outer ends,y the `links 401, -saidll-i'nlzs beling secured at their upperv ends as a-t'141 to the sai-d cable 36.7" l l* Wound about the section 29 of the cablex27 but? in an opposite direction tothe cable k36 is a similarfcablef42, said cable passing yupwardly through the top 14 of the .derriek and over the VVpulley 21, the free endof the .cable having secured' thereto a yclamping member* the like 3 4 `about which is adapted to be 43 which is similar in .constructionto the clamping' member 37.

form `11 are the 4spaced l.bearing `bloclrsl 44 and 45 within which is` journaled the :shaft 46 carrying -the pulley 47 and trained :around this pulley and the; section f3() of the reel `27 is the endless cable 48. Seeuned overthe4 Positioned at the forward-end of thegplat endless cable 48 are the tubular sleeves or` the like 49 and 5() to which are pivotally connected asat 51 and 52, the hooks 53 and 54, each of said sleeves beingfprovided with a suitable clip or the like 55 to which the said hooks may bel detachably secured when they are not in use.

Carried by the platform 11 are the spaced guards 56 and 57 and by reference to Figure 4, it will be clearlyk seen that each et the said guardsis of substantially inverted V- shaped formation having the substantially vertical leg-58 and the slanting leg 59, vboth of said legs having the feet 60 by means of which the same may be secured to the plat "form -11. The lower run 61 of the endless cable 48 is arranged to pass between the legs y58 and 59 of the guards while the upper run 62v of the said endless ycable is positioned eXteriorly of the vguard and this construction is provided so as to prevent theArods being removed from the well from crowding 'the cable as they are lowered.

In the operation of the present invention, it will of course'be understood that as the reel 27 is rotated, in one direction, the cable 36 will be wound about the reel while the cable 42 is unwound,and as the reel is rotated in the opposite direction, the cable 42 will be wound about the reel while the cable 36 will bey unwound. Also, that the endless cable 48- travels at all times in the direction of rotation of the reel.

The numerals 63 yand 64- denote two rod vor tube 'sections and it will be. seen upon referencetoFigure 1' that the section 63 has been vremoved from the well and is held thereabove by the clamping member 43 while the section 64 is engaged by the clamping member 37 and islre'ady to be pulled. will also be noted that the hook 54 is engaged with the lower end of the section 63.

Let usk now assume that power 'is applied tothe drive pulley 34 through the medium ofthe belt 35 and thereel 27 is caused to rotate in an anticlockwise direction.. This rotation will cause the cable v36 to be wound upon the reel 27, the cable 42 to be unwound therefrom andv the endless cable 48 to be moved in an anti-clockwise direction. As the cable 36 is wound upon the section 28 of the reel, the rod vo r tube section 64 will 4be pulled from the well to assume the position of the sect-ion 63 shown in Figure 1.

`Simultaneous with this operation, the cable `42 will be -unwound from the section 29 and 'the endless cable 48 will move in an anti.-

V.same-outwardly so that the section will assume a horizontal position. When the scc tion is clear of the derrick, it can be detached from the clamp and moved to any :suitable place;v

When this operation has been completed, the section 64 will be in the position of the section 63 and the clamp43 which has been lowered, can then be secured to the neXt section to be pulled. The hook 53 is then secured to the bottom of the section 64 and the reel is operated in the opposite or clock- Vwise direction with the result that the cable be understood that various changes in the details of construction thereoi may be found desirable yandthat any such changes as properly fall within the scope of the appended claims may be resorted to without departing from or exceeding the scope of the invention.l n l lVhat'is claimed is: i 1.
