LAWRENCE WrROGERS, OF ZEELAND, OKLAHOMA.
CUT-OFF.
To all whom z't may concern:
. Be it known that I, LAWRENCE W. ROGERS, a' citizen of the United States, residing at Beland, in the county of Muskogee and State of Oklahoma, have invented certainnew and useful Improvements iii Cut-Gifs, of which invention to prol and improved means coacting with a cut-ott or stop interposed in ja pipe line leading from a tank or thelike and which eonsists'ofa member serving to automatically throw the cut-ottl or stop into a or stop and which latch is released through the medium of the buoyant member Heating upon the fluid within the tank. The invention consists in the details of construction and in the combination and ary im# proved cutoff whereby'certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, aswill be hereinafter more fully set forth.
he novel features of hereinafter be definitely claimed.
In order that my invention may be the betnow proceed to de scribe the saine with reference to the accompanying drawings, wherein:
iigui'c l is a somewhat diagrammatic view partly in elevation and partly in section A a cut-oliconstructed in accdrdance with an embodiment of my invention; and
Fig. 2 is a view part-ly in sectionand partly in end elevation, with certain parts omitted, included.
As disclosed in the `awcompanying drawings T denotes a storage tank for oil of a.
Specication of Letters Patent. Application filed March 13, 1918.
.mann er with the my invention will open position of niy improved cut-oli` as herein.

conventional type and which has leading therefrom a pipe line v.P through which the oil is to be drawn from within the tank through the medium of a pump. (not shown) as is well known.` Coacting in a well known pipe line P at a point in close proximity to the tank il is a cut-off or stop of a conventional type and which serves to close the pipe line P when the tank T is substantially emptied of its contents.
t is now the general man to manually when the tank is substantially emptied, but it is my purpose to provide means whereby the cut-ofil or stop will be automatically thrown into closed position when the tank T is substantially emptied and for which purpose the core or plugl C of the cut-ofi' or stop is provided, exteriorly of the line P, with the operating' arm l to the outer end portion of which is suitably anchored an extremity of a. retractile member 2 and the opposite end of said member 2 is siiitablv secured to a casting 3. As herein disclosed the ret-ractile member 2 comprises a conventional coil spring possessing the requisite tension to iinpart the necessary turningmovement to the core or plug C'to throw the same into closed position and which requires substantially a one-quarter,revolution of said core or i l he'casting 3 as herein disclosed embodies a plate having its uriner marginal portion defined by a Hange 4 underlying the pipe line P and which has secured thereto the cleats 5 straddling the line P and whereby e casting- 3 is supported in proper position by thepipe line P.
he extended portion C is also provided with a ing in a C whicl of the core of plug rock arm (3 extendirection away from the arm l and occupies substantially a horiwhen the core or plug C is in to permit the desired How through the line P Pivotally engaged intermediate with the outer plane influence of the retractile member 2.
y 11ov thereof in locking engagement with the lever 11 is an end arm 6.
As herein disclosed the rear endportion of Athe lever 11 terminates lbeyond the casting 3' and secured to said extended portion of the portion of a fiexible member 14- preferably a chain. The member 14 passes upwardly and is disposed guide pulleys 15 and 16. The guide pulley 15 is mounted at the top of a wall of the tank T while the pulley 16 is supported by the cross member 17 connecting the upper end portions of the vertically disposed guide rods 18 -arranged within the tank T and extending substantially the entire height thereof:
"The opposite extremity ofthe member'14 is secured to the buoyant, member or float 19 positioned between vthe guide rods 18 and provided with the diametrically opposed outstanding ears 20 through which the rods 18 are loosely directed and whereby the buoyant member or ioat 19 is positioned for vertical movement in a fixed line of travel.
VVhen'the tank T is filled with oil the buoyant ,member or oat 19'is positioned ad jacent the top" of the tank and portions of the member 1 4 rest upon the ground exteriorly of the tank. As the oil is withdrawn from the tank through the line P the fioat 19 will descend with'tlie level of the oil and when the tank T is substantially emptied of Vits contents, the weight of the fioat 19 will serve to rock the lever 11 to disengage the lug 12 from the lower end portion of the latch bar 7. Upon this release the retractile member 3 will automatically throw the core or plug C into closed position and thereby prevent tht` pump from drawing air through the line l. and which would otherwise retard the pumping operation in connection with other tanks. When the tank T has been reltillcd thi` core or plug C of the cut-off or over the .a normally horizontal lever stop is manuallythrown into open `position and the latch bar 7 and lever 11 re-set.
From the foregoing description, lit is thought to be obvious .that a cut-ofi' constructed in' accordance with my invention is particularly well adapted for use by Areason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.-
I claim:
In combination with an oilV tank, a pipe line leading' therefrom, and a core ,of a stop interposed 1n said line, a plate supported'directly by and depending from the pipe line adjacent the stop, an varm extending from the core exteriorly of said line, said arm being substantiall parallel with the adjacent portion of the hnewhenthe core is in open position, a second arm extending from the core exteriorly of the line andv disposed in a direction away from the first named arm, a retractile member secured to the outer end portion of the throw automatically the core into closed position, a vertically disposed latch-bar pivotally engaged with the plate and eoacting with therfree end portion of the first named arm for holding the core against movement under the influence of the retractile member,
ivotally engaged with .the body below the atch bar and coacting with the lower latch bar for holding eratve-engagement with arm of" the core, a buoyant body within the tank and rising and fallin the first named arranged with the level of the fluid therein, and a exible and connection between said buoyant body the lever. 4-
In testimony whereof I hereunto affix my signature in the presence ot two witnesses. LAWRENCE '"W. ROGERS.
