TUBING HOLDER.

Application led October 18, 1926, Serial No. 142,210. Renewed April 8, 1928.

This invention relates to new and useful improvements in a tubing holder.`

One object of the invention is to provide a tubing holder embodying an adapter de- 5 signed to be mounted on a casing head and a tubing slip` adapted to be inserted into said adapter around the tubing to be held. v

Another object of the invention is to provide, in a device of the character described, a plurality of.m

jaws are mounted whereby'the jaws may be conveniently handled.

W'ith the above and other objects in View the invention has particular relation to eertain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a plan View of the apparatus.-

Figure 2 shows a side elevation thereof. Figure 3 shows a\ vertical sectional view taken on the line 3-3 of Figure 1.

Figure 4 shows a fragmentary longitudinal sectional view of one of the slip handles, and

' Figure 5 shows a fragmentary vertical ure 1. v

Referring now more particularly to the drawings, wherein like numerals of .reference designate similar parts in each of the figures, the numeral 1 .designates a, well casing having the casing head 2, of conventional construction, secured thereon. pump is attached to the lower end of the pump tubing 3, and is let down into the casing and in lowering said tubing, or in with` drawing it,'the tubing holder hereinafter described, is employed. The numeral 4 designates the adapter, as a whole. This adapter is'formed of two sections 5, 6, preferably arcuate in form, and whose'abutting ends are formed, one with a vertical dovetailed tenons 7, 7, which fit into mortises 8,"

v 8, of the other section, land the respective sections are formed withv the outwardly turned end flange 9, the bolts v10, 10. This adapter is mounted on the casing head and secured thereon in any lsuitable manner and is formed with the downwardly converging seat 11, adapted to receive the tubing slip.

readily conform themselves sectional view taken on theline 5 5 of Fig- The 9, secured together by' This tubing slip is composed of the vertical confronting clamps 12, 12, which are hinged together at one end, as at 13, and whose other ends are 'outwardly turned and formed into the handles 14, 15. The undersides of the clamps 12 are formed with the arcuate grooves Y16, 16, which are contracted downwardly and 'each clamp 12 carries plurality of depending tubing engaging jaws 1T, whose outer sides taper taper of the seat 11 and whose inner sides are toothed so as to readily engage the tubing The upper ends of these jaws 17 are formed with the tenons 18, whiclrare fitted into the grooves 16 and are retained therein bymeans of set screws, as v19, which are screwed downwardly through the clamps to eonform'to the l2, and Whose lower ends piojectl loosely into the'oblong recesses 20 in the upper sides of the tenons 18. The jaws are thus swung from the clamps 12 and have fi'eedoin of movement within a restricted rangeso as to to the tubing to be held by them.

The free end of the handle 15 is bifurcated, and mounted between the lingers thereof there is a swivel block 21 having 'the square bearing 22 therethrough through which the rod 23 slides. The inner end of this rod normally projects into the socket 24, of. t-he handle 15 and has a stop 25 secured thereon and interposed between this stop and block 21, and surrounding the rod 23 is a coil spring 26. The outer end of the rod 23 has a suitable eye 27. The free end 0f the handle 14 is provided with a transverse slot 28 and when itis desired to secure. the slip around the tubing 3 the handles 14, 15, are swung together and the rod 23 is', then pulled outwardly and swung around with the block 21 and its outer end is engagedthrough the slot 28, the eye 27 forniing means for preventing the disengagement of the handle 14 from said rod 23. The slips may thus be conveniently secured around the pump tubing'and will sustain the tubing suspended in the well casing'and if in handling the tubing it should be elevated so as to lift the slips out of the adapter, said slips will not release the tubing, but when the tubing is again lowered they will seat in the adapter and prevent the tubing from dropping on down into the bore.

los`

henv it is ldesired to release ythe tubing the handles 14, 15, may be unlatched and the swung open,

' cluding ana tubing slip77 elevated` to clear the'adapter and then ing on the top` of the adapter. .The adapter is provided with an` outwardly inclined inverted U-shaped rest 29 against which lthe slip,when infopen position, may rest, so as to hold it out of the way of the work, and yet in readiness at all times to be applied around the tubing when necessary.

What I claim'is:

- l. A device of the adapter having an upwardly iiared opening, a tubing slip adapted to seat in said opening and an upstanding membeil carried by the adapter andV disposed to one side of said opening and'independent of the slip -but formlng a rest for said slip tohold it in convenient position for seating' the same in said opening?. y

2. In a device of the character described, slip including confronting clamps hinged together at one end, outwardly extendingthandles lcarried by the other ends of said clamps, the under sides of the clamps having arcuate mortises, tubing engaging jawsA having tenons on their upper en which work loosely in said mortises and having their lower ends free and radially movab e.

3. In a device o f the character described, a tubing slip including confronting clamps hi togetherat one end, outwardly exnled ten 'ng handles. carried by theother ends the lower ends of the jaws rest.

5. A tubing slip 'including a` sitel'y disposed clamps hinge one end, outwardly extending handles carried by the other ends of the clamps, the

free end of one handle having a transverse a latch rod having a swiveling and a. ds yieldable connection with the other handle slot,

and adapted to be engaged through said slot to secure said handles together and tubing engaging jaws depending from said clamps and having their lower ends free.

.In testimony whereof I have signed my mme.
