HYDRAULIC swIvEL.

To all whom it may concern:

Beit known that we, MAHLON E. LAYNE, SAMUEL N. HALL, and CHARLES F. LAYNE, citizens of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Hydraulic Swivels, of which the following is a specification.

The invention relates to swivels for use with well apparatus, and has for its main objects; the provision of a novel swivel construction of more compact form than those heretofore employed and one in which the cost of construction and weight of metal are reduced to a minimum; the provision. of a swivel having improved means for protecting and lubricating the bearings; the provision of improved and conveniently arranged adjusting means for the packing between the swivel members; the provision of an imings between the swivel members; the pro vision of a form of coupling means for the attachment of the hose whereby wear and twisting of the hose is avoided; and the provision of attaching means for the upper swivel member designed to prevent accidental disarrangen'ients between such means and the means from which it depends. One embodiment of the invention is illustrated in the accompanying drawings, wherein Figure l is a longiti'idi'nal section through the swivel,

Figure 2 is a partial side elevation of the swivel,

Figure 3 is a partial side elevation of the swivel taken atright anglesto the elevation of Figure 2,

' Figure 4 is a detail side eleyation of one half of the swivel bushing employed, and

Figure is a detail view ofone of the divided bushings employed.

Referring to the drawings and particularly to 1, the supporting swivel member comprises the upper membernl with the pipe 2 screw threaded to its lower end, and the lower swivel member comprises the upper section 3 and the lower section 4, which ,lattersection is adjustably mounted upon the upper section in a manner to be hereinafter described. Thefmember 1 is provided fat its up'perend-with the engaging loop 5 Specification of Letters Patent.

for cooperating with the usual supporting hook, and in order to prevent the disengagement of the hook and loop during the vertical vibration of these parts, the recess 6 is provided, which recess (3 is adaptedto receive the lower end of the hook and so prevent a lateral movement thereof tending to disengage the parts. The member 1 is provided at its central portion with a laterally projecting neck 7, upon which is screw threaded the'member 8 for adjusting the gland 9' against the packing 9 In the stufling box thus formed is mounted the coupling member 10, which coupling member is adapted to turn freely and is provided with the screw threaded end 11 for engagementwith a hose coupling. This arrangement permits the hose to swing backward and forward in the operation of the device without any twisting of the material of the hose as has heretofore been the case wherein a non-rotatable coupling was used, and furthermore permits any twists in the hose to be easily removed. This arrangement greatly lengthens the life of the hose used in this type of apparatus, the constant bending of the hose due to the vibration of the apparatus cracks and weakens the material of the hose causing it to leak after a limited period of use. The

member 8 is held in adjusted position by pin 16. :The section '3 also carries at its upper-edge a-bearing, collar 17, and a series of anti frictionballs 18 are interposed between thetwo bearing collars. A tapering bushing 19'is interposed between'the inner surface of the collar 17 and the shank of the member .1. In order that this bushing'may be self adjustingit is made in sections, and asthese sections wear they work downward thus preventing any play between the collar 17 and the shank of the member 1 andholda ing .sucl1 'parts l 1rmly in concentric position.

The packing 20 is interposed between the section 3 and the pipe 2 at a point beneath the bearing collar 15, which arrangement makes the cavity carrying the thrust bearing tight, so that such hearing may be flooded with oil and run an indefinite criod with-- out further attention. Oil may be placed in the bearing cavity through the opening which is closed by the bolt 21 (Figure 1).

The lower end of the swivel section t is screw threaded at and it is from this portion of the device that the tubular drill casing is supported. A hearing for the lower end of this swivel member 4t upon the pipe 2 is provided by means of the ring 23 which carries at its inner surface a split taporing bushing 24: corresponding to the bushing 19 heretofore described. Immediately above this ring 22; and the bushing 24: is the annular member 25 for simporting the lower end of the packing 26, which packing 26 is designed to prevent the passage upward from the lower end of the swivel of water, which might otherwise be forced upward sufficiently to obtain access to the thrust bearing cavity. In order to still further,

safe-guard against this contingency, however, a vent 27 is provided to permit the outflow of any water which should be accidentally forced up past the packing 26. As there is still another packing 20 above this vent 27, there is very slight possibility of any fluid ever gaining access to the thrust bearing cavity. in order to tighten the packing the gland 28- is provided, which gland is screw threaded to the section 4 and is prevented from rotary movement with such section 4. by means of the pin 29 secured to the lower end of the section and engaging a longitudinal slot in the gland. The section 3 is swiveled to the section 4 by means of the two part bushing 30 shown in detail in Figure l. The interior of this two part bushing is provided with parallel V ridges 30, which ridges engage correspending V grooves on the periphery of the lower end of the section 3. The outer surface, of this divided bushing 30 is provided with screw threads for coliperating withcorresponding threads on the interior surface of the upper end of the section 4-. When the parts are in the position shown in Figure 1, a rotation of the section .t will carry with it the two part bushing 3 and as the gland 28 is held against rotary movement it will be moved up and down depending upon the direction of rotation of the section 4:. The upper edge of the section 4 is provided at intervals with the slots 81 (Figure 2). and the engagement of the pin 32 (Figure l) with any one of these slots will hold the section 4 and consequently the gland 28 in adjusted position. The pin 32 is normally held in the position hown in Figure 1 by means of the swinging spring holder J3, which l l I l l l l ceases when moved to the position shown in dotted lines in Figure 2 permits of the retraction of the pin to permit a rotation of the section st. if desired the pin 32 may be held in partially retracted position by causing the edge of the member 33 to engage with the slot 3% near the head of the pin. It will be seen from the foregoing that the packing 26 may be very easily and conveniently tightened or adjusted by merely rotating the lower swivel section 4t. The two part bushing 30 makes a very convenient means for swiveling the lower section 42 to the upper section 3, but it will be apparent that other swiveling means might easily be employed without avoiding the invention it being only necessary that the part 4 be swivelly mounted upon the part are preferably assembled before the pipe 2 or the gland 28 are placed in position, and

in order to prevent the two part bushing 30 from rotating while the section 4 is being screwed thereupon, a pair of alined openings 35 are provided in the bushing 30 and lower I end of the section 3, in which a pin may be mserted until the member 4 ls'screwed up into the posltion shown in Flgure 1, at which time the pin is removed and the pipe 2 and v i the gland 28 are placed in position.

It will be seen from the foregoing that a very compact arrangement of parts is sea cured,wh1ch compact arrangement is due prlmarily to the use of the shank of the member 1 as a support for the bearing collar 15, so that the center line of the bearing balls 18 are placed at a minimum distance from the axis of the swivel, and the cumbersome bails as heretofore employed in this class of devices, are done away with. A minimum amount of metal may thus be used, theold type of construction greatly simplified and stilt'ened, and the expense of machine work reduced, as all the machined surfaces are circular and may be handled by a lathe.

The arrangement further provides for the perfect lubrication of the thrust bearing and the protection of such hearing from any fluid passing through the pipe and from all dust and dirt. The foregoing and other ad vantages which will be readily apparent. to

those skilled in the art. are incident to the construction as illustrated and described.
