` SPECIFICATION forming part of Letters Patent No. 224,090, dated February 3, 1880. Application filed September 1, 1879.

Touli whom t may concern: l

Beit known that I, CHARLES` JAREGKI, of

. Erie, inthe county of `Erie and AState of Penn- `nited.

Inboring oil-wells the tools and connecting- V cable operate through the bore of alarge pipe called a casing77 On the top of this casing is what is called a casing-head,77 which is provided with means for attaching branch pipes for conveying away the gas or oil which may come up during the operation of boring and after the well is iinished.

My device consists of a two-part ring or cap which will clamp around the cable and be seated in the top of the casing-head, and will permit the cable to move freely through it.

during the operation of drilling. The opening through this ring or cap in which the cable moves is made daring or tapering, and when it is desired to shut off the tlow of gas or oil from below a wrapping is .put around the cable and is drawn into the ring by the weight ofthe tools, and thus completely stuffs or closes that openin g and forces the oil or gas through the branch openin g in the casing-head.

In drilling oil-wells gas is often found some time before the oil-vein is reached but the ca-` ble sufficiently closes the opening in the ring to prevent any very great Volume of it from escaping at that point, andthe gas finds its way through the branch openings and is usually conducted through pipes to the boilerfurnace; but when oil is reached it is desirable to save it, and as :it is necessary to drill some dist-ance below the `vein the work of drilling has to proceed while the oil is flowing from the well. The flow of oil is, however,

`periodical and not continuous, and hence when a flow occurs the operator can wrap the cable l and let the wrapping draw down into the flarilow of oil through the ring past the cable. Of course the work ot' drilling stops during the flow 5 but as soon as that stops, which is soon the case, the work of drilling can at once be proceeded with. l o

Other devices have been heretofore invented for this purpose. (See Patents No. 129,129, July 16, 1872, to V. Gretter, and No. 200,471, February 19,1878, to E. J. Northrup.)

My invention therefore consists in an improved construction of the ring or cap.

My device is illustrated in the accompanying drawings, as follows:

Figure l is an elevation View of the top of the casing, the casing-head, and the cap. Fig. 2 is a vertical section of the saine parts. Fig. 3

is a top View of the cap and the casing-head. Fig. 4 isa side view, frorn'the right, of the parts shown in Fig. 3.

The letters of reference indicate parts as follows: A is the casing-head. B is the two-part ring or cap. C C are the clamping-bolts for holding the two parts of the cap together. D is the cable. E is the casing. F F are the branch openings from the casing-head. G is the wrap, which is placed on the cable to close the orifice in the cap. b b are setscrews for holding the cap on its seat in the casinghead. c c c c are arms extending from the cap, and which, together with the clamp-bolts C C,form the clamping device by which the two parts of the ring or cap are held together.

The casing and casing-head may be of ordinary construction.

The ring or cap B is in two parts and doweled together, (see dowel-holes d in Fig. 2,) with dowels fixed in one part and euteringdowel-holes in the other part. These two parts are gether around the cable.

The object in having the ring in two parts, with means for clamping them together, is to enable the operator to attach the devicewithout removing the cable and tools from the well.

The clamping device which I herewith show consists of two swinging bolts, C, pivoted in the arms c of one of the parts of the cap B,

'the other part, and provided `with bindingand swinging into openings in the arms c of ing mouth ofthe ring and entirely shutoff the provided with means for clamping them toy IOO nuts whichvscrew up against the outer. face of the last-mentioned arms. I do not, however, desire to be limited to this precise means of clamping the two parts together, as many other devices for the same purpose will readily suggest themselves to a mechanic.

The mouth of the orifice in the ring through which the cable passes is made flaring; and to tightly close it, so as to prevent the passage of oil past the cable, I wrap the cable with a cloth or any suitable object, and then allow the tools to settle down a little, so as to draw this wrapping into the iiaringmouth of the orice, which closely packs it around ythe cable and entirely stuffs the opening. (See G in Fig. 2.) When thus arranged, as shown in Fig. 2, no oil can escape past the cable, but must tind its way out through the branch openings F.

This mode of stuffing the cable-opening is very simple and effective. I do not, however,

claim it as my invention, as I believe it has been heretofore used.

I am aware that in the patent to G. Finton, September 30, 1873, No. 143,280, it is stated that one ot' the plates (of which there are two) which close the top ofthe casing may be made in two parts; but such a construction is not my invention, for my invention consists in making the whole device which sets in the casing-head bisected, so that it can be attached and detached while the cable is pendent in the well, and no such result can be effected by the device shown in Fintons patent.

What I claim as my invention is- An oil -saving device for oil-well casing- -heads formed of two parts and provided with a clamp whereby said parts can be clamped together, thereby permitting the adjustment of saiddevice in the casing-head and upon the cable while said cable is pendent in the Well, substantially as and for the purposes set forth.

In testimony whereof I, the said CHARLES JAREGKI, have hereunto set my hand.
