OIL-SAVER.

the oil saver shown and described in Letters Patent granted to me April 1, 1902, No. 696,747, by providing a vertically divided or two-part construction in the form of a slotted casing closure for entering the cable, with a device removably fitting and secured in the slot and corresponding thereto in size and shape, thus avoiding any break in the contour of the closure due to the slot.

A further purpose is to arrange the closure with a portion of its body beneath or below the cap portion, thereby lowering the device with relation to the casing head of collision with the temper screw which frequently works in close proximity thereto on its down strokes.

In the accompanying drawings, Figure 1 is a vertical section of a casing head with the oil saver in position thereon, the same being taken on line 11 of Fig. 2, and Fig. 2 is a sectional plan on line 22 of Fig. 1.

-Fig. 3 illustrates the improvement in side elevation. 'Fig. 1 is a top plan of the same with the packing compressor removed, also with the slot-closing member shown out of the slot. Fi 5 is a de'tall of the packingcompressing screw.

Referring to the drawings, 2 is the casing,

and 3 the casing head having the usual discharge pipe connections 4. The cap 5,

the open top of head by screws t ,is preferably formed integral with the upright body-portion 7, in the embodiment shown being located substantially midway between the upper and lower ends Passage 8 extending vertically through body 7 is enlarged above its lower end to receive packing 9 which surrounds the I cable 10, preventing oilfrom leaking as the cable reciprocates. Passage or cavity 8 is threaded internally to receive the packingg screw 11, the latter bcing-hecei shown split longitudinally, as in my former patent, so as to be readily applied and re- 1 moved. At one side of passage 8, body 7 t Specification of Letters Patent.

and cap 5 are formed with a vertical cableentrance slot 12 in which is titted the closing member 13, having a part 11 corresponding to the slotted portion of body 7 and part 15 corresponding to the slotted portion of the cap, so that when said device is in place there is no break in the contour of either the body or cap due to the slot 12. Closing device 13 may be formed above and below cap portion 15 with lugs 16 which fit betweencorresponding lugs 17 on body 7 with screws 18 extending through apertures in the lugs and holding member 13 in place. The inner face of the upright portion 14 of the slot-closing device 13 is threadedlto former devices, and hence is not so liable to be struck by the temper screw which on the down stroke of the cable frequently works quite close to the oil saver.

T he improvement is of simpleconstruction, and minimizes the danger of leakage.

I claim:

1. A casing closure formed with a vertical passage through which the cable 0perates, packing and packing compressing means in the passage, the closure at one side of the passage formed with a vertical cable-entrance slot, and a member removabl v fitting within and closing the slot, said member shaped in conformity with the closure and when in place preventing any break in the continuity of the closure due to the slot.

2. A casing closure consisting of a body having a vertical cable passage of sufficient size .to receive parking around the cable, a cap member carried by the body for closing a casing-head ope ing, the body and cap at one side of the passage formed with a vertical cable-entrance ably secured in the slot and corresponding in size thereto. and packing compressing means cooperating with the closure.

3. A casing (lOStlIC consisting of a body having a vertical cable passage of suflicient size to receive packing around the cable, a cap member projecting laterally from the body with a portion of the latter beneath and a portion above the cap, the body and the cap at one side of the vertical passage .ot, a member re1nov-' formed with a cableentrnnc'c slot, a device reniovahly secured in the slot with portions of said device corresponding in size to the slotted portions of the body and cap respectivel coiiperatmg with the closure.

4. A casing closure consisting of a body having a vertical cable passage of sufficient size to receive packing around the cable, a cap member projecting laterally from the body with. a portion of the latter beneath and a portion above-the cap,,tl1e body and the cap at one side of the vertical passage formed With a cable-entrance slot, :1 deriee' fitting the slot with portions of said device corresponding in size to the slotted portions of the body and cap respectii'elg', laterally projecting lugs on the body and on i said device both above and below tliil pap,

means securing said lugs together, end

-packing compressing means cooperating with the closure.

y, and packing, compressing means l 5. A casing closure consistin of a body, 1 a cap carried by the body for c osing 1 casing head, the body having a vertical cable l passage tlierethrough enlarged downwardly from. its upper end to recelve packing and threaded internally, the body and cap formed with a vertical cable-entrance slot, a device reniovably secured in and closing the slot with its inner-face threaded to form continuations of the threads of the body Jpassage, said device having portions cor-m respondingin size to the slot in the body and cap, and a threaded packing-compressor eml'n'acing the cable and engaging the threads of the body.

In ttgtimony whereof I affix my signature in two witnesses.
