Application filed A r l a, 192 se ial No. 99,661;
This invention relates to oilsavers for use on cables of oil wells. V
' a An important object of theinvention is to produce 1 a device of this character which eifectually prevents the loss ofoil and what ismore important, the spilling ofthis oil upon the deck of a derrick and which accomplishestheseends without applying friction to the cable line which would tend to roughen'and finally destroythe same;
In the 'ordinaryii'orm of oil saver employed with cable lines,a packing is provided for the cable; lineot itself with the result that the cable in its reciprocation in the packing becomes worn and the various strands'of the outer surface thereof broken so that they project and engageinthe packing, rapidly" rehdering the same useless. Furthermore the cable line by the breakage of its strandsv becomes-weakened so that it niay part and falling-into the well renders an expensive and lengthyfishing operatlon necessary. Accordingly, an important object of this invention isto' provide a oasi-ngifor the cable line which in itself forrns a packer and. prevents capillary movement oi lthe oil alongthecable line, this casing beingrin turn operatedthrouglr a packer which will pre vent the-passage of oil upwardly. upon the casing. y i
A- further objectoii theinvention is to provide a device of the characterjustdescribed which may be applied to the cableline with out the necessity of threadingi'the various portions thereof upon the cable line, thus eliminating necessity, for disconnectlngthe cable line in such application is a section on the line; 5,5

, Referring now more particularly to the i" drawings, the numeral 'lll gene rally designa-tes the control'head of'anoil well andll the cable'llne passing therethrough which is to be packed. These cables are reciprocate'd through affiXeddista-nce and in accoi'den with my invention, "I-slecure" about the cable:

Q 1 brought into firm engagement With the cable.
:. Whenthe packinghas been properly compressed, the packer may be secured'in adjusted'position by further tightening of the securing element's 26; @Tli'e upper packer 14 ,isgf-ormed in two hingedly connected sections 30 and -31 which' may. be secured in assembled relation.byla S6CL11'lI1g' element 82. 7 These elements corn gio bine When in assembled relation to provide a threadedbore 33, the threads of which coact withthe threads atth-ejupperend of the easing' 12 and with the sections of: a'two; part I gland follower 35;.
The section 30 has an upstanding .toi'which is pivoted a block 37 forming "onehalf of a Cable 'clamp, the other half of whichis formed by a cap 38 adjusted with frel ation tQQthe bloclrg'f byimeans of a, U- .bolt 39 or thelike. It will,'of course, be understood that the'opening '40provided may have its facesgrooved after the manner of ithe usual cableclampfor coaction with the threads of' the cable. 'VVhen not in use, the
cablefclamp may befswung t o the po sition,
generally. indicated at Figure 2, and-in this position,"'will not'interfere in any way with hoisting of the cable through the casing ,12'.
I This cableclamp forms a means for preventing relative movement of the 7 cable and as ng etfa lFt me du g a y OPP ip'ns ourseqa h n h Cable. i being drawn through the. casing 12, there will be relatve move of a 'a Pack "ings carr'iedby the casing at the ends thereof,fbutjthis relative,movement is suchthat thejfrictio'n applied to" the cable is'.-dis- :tributedthroughout the length thereof and e not confinedgto one point, as the case 4o -wherefthe cable continually reciprocates w throughthe'packing. 4
. fFThepacke'r 16 has a throu-ghx its upper end of greater sizegthan fthe'i asing and' threaded .to receive a two part gland follower 42. The lower end of bore 41 opening this boreis reduced byan inclinedj shoulder r "42 to the diameter of the casing. 12, the
shoulder 43 forming the lower gland wall follower'42, packingv 44 may be compressed lsembled aboutthe line and the upper end thereof threaded into :the'lower end of the packer 14. Packing is then placed in "the upper end of the packer 14 and the two part gland 1 35 inserted. The lower packer s then assembled about the rod, packing inserted therein from the upperend and the packer moved bodily upon the line and threaded to thelower end of the casing 12.
The packer 16. for the'casing, with the block V 46iiremoved, is thenplaced in position upon the casing 12 and the block 46 inserted. Packing-is then introduced in the packer from the upper end thereof. and the .two.
part gland 42 inserte dii 'l he packer-16 1 is then seated upon the; control head 10 and secured:inpositionby the set-screws 15, and
the device is-ready for operation. It will beneted]. that allJof the'above operations are performed without disconnecting the cable.
It will also benoted'that the packings in all -of the packers 13,14 and 16 mayberenewed Without shifting the position "of the casing upon the cable line and without the necessity of releasing the 'casingso: that it may jmovejupon the rod line. 7 V.
operative structure of the cable clamp and Particular attention is directed to the cothe upper :packer' 14. Itwill be seen that the gland 3,5 is of such length that it may be .withdrawn entirely without having its "movement; obstructed by the clamp. 7
Since the construction hereinbefore set forth is xca pable of a certain range of change and modification without materially departingfrom the spirit of the invention,-I do not limit myself to such specific structure except as hereinafter claimed. 7
Iclaim:"- 1 1.
