(c1. asa-sse) 3 Claims.
I ated in a manner to release or effect the removal of the collar from the sleeve on to the drill pipe,
such as are shown in our co-pending application, Serial No. 286,410, led July 25, 1939, for Method and means for positioning expansible collars on pipes or the like.
It is an object of this invention to provide.
meansA whereby. rubber collars or protectors may be quickly installed upon drill pipe or the like either when the pipe is disposed vertically in the oil well derrick or when it is lying horizontal, as on racks. In this connection it is va particular object to provide means whereby a plurality of collars may be expanded upon what will be called transfer sleeves and to provide a single means for use in conjunction with the sleeves for removing the protectors from the sleeves, the' transfer sleeves being detachably connected to such means. n
Itis also an object of this invention to provide a new and improved type of apparatus for use in causing relative movement between the transfer sleeve and an expanded rubber collar thereon and also to provide a new and improved transfer sleeve embodying such means.
These and other objects will be apparent from the drawing and the following description there- Fig. 1 is an enlarged sectional elevation of means for removing a collar from a transfer sleeve shown in conjunction with a transfer sleeve;
Fig. 2 is an elevation of the apparatus of Fig. 1-
shown in operative position;
Fig. 3 is a sectional plan view on line 3 3 of Fig. 1; and
Fig. 4 is an elevation partly in section of a transfer sleeve embodying another'form of the invention.
The invention contemplates the utilization of what will be termed transfer sleeves for receiv- These transfer sleeves. indicated by numeral I8 in Figs. 1-3, are of sufcient diameter so that they may be moved over a drill pipe to any desired position and used in conjunction with other apparatus for removing the protector from the sleeve. Referring to Figs. 1 to 3, it is apparent that one end of the tween the protector and the sleeve.
of. Referring to the drawing which ls for illustrative purposes only;
transfer sleeve is provided with interrupted screwquickly-connected to a means generally indicated by numeral 45 for causing relative movement be- 'Ihe means 45 includes what will'be termed an annular housing 46 provided with a recessed end 4l having lnterruptedscrew threads 41' therein to receive the threads I8 of the sleeve.
The housing 45 is provided at one end with wall means 48 forming an annular chamber 48'. This chamber may be provided with uld under pressure by means of openings 49. The wall means 48 is tapped at intervals to accommodate a plurality of cylinders 50. In the form of the lnvention shown four such cylinders are shown threadably mounted in the holes 5I. Each cylinder is provided with a piston 52 and piston rod 53. The rods extend through cap or end closure elements 54 at the opposite ends of the cylinders and terminate in a collar engaging ring 55. This ring is of sumcient diameter to accommodate the sleeve i8.
When pressure fluid is admitted to the chamber 48 and consequently to the various cylinders the pistons 52 are effective to move the ring 55 downwardly to engage an end of an expanded protector 32 which had previously been expanded and mounted in expanded condition on the sleeve and to force the same olf of the sleeve as shown in Fig. 5. The sleeve i8 has been shown longer than is essential for the accommodation of the ordinary drill pipe protector in order that the sleeves may be long enough to accommodate what are known as drill pipe stabilizers which are similar to protectors but are longer than protectors and of greater wall thickness.
It is apparent that it is possible to expand the protectors on; to the sleeves I8 at any suitable place. A plurality of sleeves I8 may be utilized and transported with the expanded protectors thereon to the location of the drill pipe. The sleeves may then be quickly consecutively attached to the means 45 shown in Figs. l to 3 which is effective for removing the protector from the sleeve on to tne pipe. If desiredof course an apparatus can be provided wherein the sleeve I8 and means 45 are integral.
Referring to Fig. 4 there is illustrated a transfer sleeve embodying another form of the invention. This device comprises an elongate tubular member or main sleeve 58 upon which is mounted a housing means 59 forming an annular chamber 6l) provided with what will be termed a piston element 6I.
The housing means 59 includes an outer tubuv lar wall 62 which is provided with an inwardly u extending flange 63 by means of which the member may--be secured to the sleeve 68 in any suitable manner as by the screw threads 64. Slidably mounted in the chamber 60 isvthe aforementioned piston element 6i which comprises a piston head 65, a sleeve 66, and a protector or collar engaging ring 61 secured't'o the end of the lmember 66 by screw threads 68 or in any other manner. The piston head 65 is provided with suitable packing rings as shown. The sleeve 66 extends outwardly of the chamber 60 which is closed at its lower end by a ring and packing gland 1 I.
-In the operation of the device pressure uid may be admitted through an opening 12 to move the piston element 6I relative to the sleeve 58 whereby the ring 61 may engage an end of a collar positioned on the sleeve and force the same oil of thel sleeve. The piston element may be returned to its original position by admitting a pressure fluid through an opening 13 in the member 62 and -by permitting release of the pressure :duid through opening 12.
It is contemplated that various changes and modifications may be made without departing from the scope of the invention thus, for example, the portion of the sleeve 58 extending beyondthe housing means 59 might be made detachable from the remainder of the apparatus in the manner similar to the apparatus shown in Fig. 1, and it is therefore intended to cover such modifications as come within the claims.
