3 @laims. (Cl. Elli-Jill) lhis invention relates to well tools and equipment and it has particular referenceto a combined rod hanger and tubing rack forwell derricks.

The principal object of the invention is to provide an economically elficient and safe means for suspending and retaining sucker rods in the derrick whereby the disadvantages present in the customary handling of rods is overcome as well as the accidents resulting from accidental release of the rods, which frequently causes injury to workmen on the derrick floor.

Another object of the invention is to provide a rod hanger which is pivotally displaceable relative to the point of operation on the derrick floor in order that the rods, when pulled and suspended may be moved out of the way so that the operation of pulling tubing may be carried on without interference.

Another object of theinvention is to provide a new and novel g-rapplingand hoisting means which lends materially to the ease and readiness by which the rods may be brought to rest inthe hanger by an attendant as well as positively preventing accidental release of the rod while the same is being placed in the hanger.

Another object of the invention is to provide in combination with the rod hanger, a platform serving as a tubing rack and which platform is adjustable relative to the rod hanger as well as other points of operation on the derrick floor, such adjustments being advantageous as regards both the platform and the rod hanger since operations may be carried on on either side of the central point of the derrick depending upon wind and weather conditions and the like. Both the tubing rack and rod hanger may be moved out of the way of operation at any time desired and locked against accidental displacement from any position to which they may be moved.

With the foregoing objects as paramount, the invention has particular reference to its salient features of construction and arrangement of parts, which will become manifest as the description proceeds; taken in connection with the accompanying drawings, in which:-

Continuing with a more detailed description of the drawings, reference is primarily made to Figure 1 wherein l designates the leg of a conventional steel derrick, the braces and girts being designated by the reference character 2. First, the bolts 3 shown in Figure 13 are removed 'pr'eparatory to mounting the brackets 4 which serve to support the invention at a convenient location above the derrick floor 5. It is apparent that by removing the bolts 3, the derrick is not weakened at any point while the brackets-4 are being aplid plied. The brackets l correspond inshape to the angle of the leg I and therefore conformably fit.

.The upper bracket 4 is held in position bybolts 6 while the lower bracket is secured by means of of which are aflixed to a pintle or block III which is disposed in the recess position of the bracket 4 and pivotally held therein by a pin II. The confronting edges a of the members 9 are beveled as shown particularly in Figure '7 and these edges conform with the annular V-shape groove in a roller I2 which is mounted on a roller hearing I3. The shaft I4 on which the bearing I3 is mounted extends through the walls of a member IS, the latter being comprised of relatively spaced parallel members embracing the members 9. The outer ends of the members comprising the member I5 are joined together by a plate I6 as shown in Figure 1 and held in fixed relationship by pins or bolts IT.

The shaft I8 is carried by the free end of the member 9 as shown in detail in Figure 8 and each end of this shaft carries a roller l9 having a V- shaped annular groove therein to conform with the beveled confronting edges b of the members comprising the member I5. It is apparent from the foregoing that the arrangement provides for sliding movement of the member I5 upon the member 9 and which enables its operator or attendant to properly adjust the member i5 which is the rod hanger relative to the point of operations, thereby making it convenient to properly dispose the rods in their respective retainers.

The rod retainers are constructed in the manner shown in Figures 2 and 3, each being formed of a substantially circular casting 20, each having a recess breaking the continuity of the circle and they are further provided with a stationery gripping member or slip 2| and a removable slip 22. A dove-tailed projection 23 is provided on each retainer 20 to be conformably received by recesses 24 on each of the members comprising the rack I5. The retainers 20 are also provided with recesses 25 on one side, the purpose of which is shown in Figure 3, i. e. to provide means for receiving and holding the removable slip 22 in a position accessible to the operator or attendant.

The member 9, as shown in Figure 6, has an opening 26 therein to receive a wedge shaped pin 21, thepin being held in the opening by a key 28 connected to the endof the pin by a chain 29 to prevent loss thereof. Asupporting cable 30 is connected to the pin 21 and extends to the top of the derrick or to some suitable point in the derrick to carry the weight of the rod hanger and its load of rods. An eyelet 3|, shown only in Figure 1 is provided, to which is connected a cable for the purpose of raising the rod hanger to a position to be mounted.

The outer end of the member 9 supports an upright 32 and pivoted to the top of this upright by means of a bolt 33 is an arm or crane 34. Referring to Figure 10, a grooved roller 35 is mounted in either end of the arm 34 and a cable 36 is passed over these rollers and lies within a groove 31 in the arm 34. The cable 36 continues over a roller 38 mounted in the upright 32 and downward through an aperture in a lever 39. A series of stops 40 are provided in spaced relationship on the cable 36 and are shaped to conform to the shape of the aperture in the lever 39 so that they will not pass through the aperture.

Through this arrangement, the cable 36 may be lengthened or shortened as desired.

Suspended from the other end of the cable 36 is a grapple or elevator 4|. This elevator-is shown in Figures 14 and 15 in detail and is comprised of a bifurcated member 42 having mounted therein a grooved member 43, the latter being pivoted at.44. A shoulder 45 is provided on the wings of the member 43, for a purpose to be explained later. Normally, the elevator is in the position shown in Figure 15 and when it is desired to engage a rod 46, the body 42 is pivoted to the position shown in Figure 14, in which position the squared end of the sucker rod 46 may be readily inserted into the recess of the member 43, the shoulders 45 serving to prevent release of Lie rod and the weight of the latter will cause the body 42 to move into the upright position shown in Figure 15, in which position, the rod 46 is positively locked against escape or accidental release from the member 43. The pivotal point of the member 43 at 44 is offset relative to the connection of the cable 36 with the body 42 and this fact is a further insurance that the rod 46 will not be released from the elevator until the rod has been moved through the opening 0 of the retainer 20 and secured by the slip 22. After having been thus secured, the body 42 is manually returned to the position shown in Figure 14 and the elevator may be readily removed from the rod 46.

As the rods are elevated or withdrawn from the well to a position for reception by the elevator 4|, it is desired that the cable 36 be secured against movement. A locking means for this purpose is shown in Figure 6 and is comprised of an eccentric 41 pivoted at 48. A lever 49 is provided to actuate the eccentric 41 so that it will bear against the cable 36 and urge the latter against the periphery of the roller 38 with a wedging action. The greater the pull upon the cable 36, by the weight of a rod or the like, the more secure the locking means. Downward pressure upon the lever 39 will relieve the wedging action on the cable 36 and release the eccentric 31 to the action of the spring 50. The crane may be .then manipulated by the lever 39 to bring the suspended rod into proper position for reception by a selected one of the several rod retainers 20.

The fact that the rod hanger is movable orlongitudinally adjustable, allows the operator to change the position of the retainers 20 at will to render less burdensome the work of mounting the rods in their respective places in the hanger.

As a means for supporting the attendant or operator during the operation of pulling and 5115- pending the rods, a platform isprovided and which serves also as a tubing rack. This device I is comprised ofa substantially rectangular member whose normally operative position is shown in dotted lines in Figure and has a series of recesses 52- in one side thereof to receive sections of tubing. The member 5| is pivoted at 53 to an outwardly extending arm 54. This is shown in detail in Figure 9 as well as in Figure 1.

The arm 54 has an enlarged end or pintle 55 which is received in the recess of the lower bracket 4 and pivotally held therein by a pin 56. The pivotal relationship of the arm 54 with the bracket 4 allows the former to be moved to any position desired. As a means for looking or temporarily holding the platform 5| in adjusted position, a corrugated boss 51 is provided on the pintle 55 of the arm 54 which corresponds with the opposite side of the point of operation. These 7 a similar boss 58 on the bracket 4 as shown in Figures 4 and 5. In addition to thistemporary of the arm 541s beveled at d. This feature all--- lows the platform 5| to be tilted as shown in dotted lines so that it may be more readily rtated to adjusted position relative to the supporting arm 54.

While rods are being handled on one side of the point of operations, the platform is shown properly adjusted in Figure l and secured by means of a boltBl'L Apertures 6| are provided at four corners of the platform so that the latter may be reversed in its position relative to the arm 54 should the operations be carried out on features. of adjustment are likewise important when the platform is loaded with tubing and moved aside out of the way against one side of thederrick in the manner shown in Figure 10.

It is of course preferred that the platform or tubing rack lie flush against the side of the derrick as illustrated both in solidlines and in dotted lines in Figure 10, depending upon which side of the point, of operation the work of loading the rack is carried out.

In Figure 12 is shown a detail fragmentary.

view of the platform or tubing rack 5| in order to illustrate a stop or guide 62. The guide 62 slides within a dove-tailed recess 63 and may be secured in adjusted positions by virtue of apertures 64 into register with which is moved an aperture 65 in the guide arm 62.. A suitable pin or bolt inserted in the apertures will hold the arm 62 against longitudinal -movement. The outer end of the arm 62 is concave at 66 so that a section of tubing may be rested thereagainst A ring 61 is provided midway between the ends of the platform for the purpose of receiving a cable by which the platform is elevated to a point in-the derrick for mounting and in addition, a pair of hooks 58 are provided on one side of the platform adapted to engage over the girt 2 of the derrick to hold the platform against release when in the-inoperative position shown in Figure 10. Y 7

As a means for holding the sections of tubing within the recesses 52 of the platform 5|, ap-

ertures 69 are provided therein between the recesses 52 through which a rod is passed.
