TUBULAR-TANK INSPECTOR AND GAGE.

Specification of Letters Patent.

Patented April 2, 190'?.

Appiication iiled March 12,1906. Serial No: 305,680.

' Be it known that I, W rLLrAM GREGsoN, a citizen of the United States, residing at' Beaumont, in the county of Je'erson and State of Texas, have invented certain vnew and useful Y 'plm rovements in Tubular-Tank Inspectors an Gages, of which the following is a specification.

The-present invention relates to improvements in gages, and relates particularly to foil-gages and inspectors.

The object of the invention is the provision of a gage for terminating the depth of iiuids contained in a tank or other receptacle, and when usd\for the purpose of measuring crude oil in vessels it serves to ascertain the quantity of oil and water in the tank and also the quantity of sediment which is usually found 1floating between the crude oil and water contained in the tank or reservoir.'

The invention consists of a gage-tube suit# ably secured to a pole and provided with stoppers or valves at the top and bottoni for preventing the escape of the fluids contained in :the tube after the gage has been inserted in- -and withdrawn from a tank, together with means for actuating said4 valves by pressure upon the.pole or by means, of connections controllable from the top of the pole.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In' the accompanying drawings, Figure 1 is a front elevai ion of a gage 'constructed in accordance with the invention. Fig. 2- is a rear elevation of said gage with the gage-pole removed. Fig. 3 is a side elevation illustrating the gage attached to the gage-pole, andA Fig. 4 is a plan view of the device.

Like numerals designate corresponding parts in all of the figures of the drawings.

Referring to the drawings, the numeral 5 designates a gage-pole which may be of any desired length and which has secured toits lower end a tubular casing 6,which forms the body of the gage. 'The tubular casing 6 has secured thereto rearwardly-extending clam ing) members 7, which are secu-red to the po e 5 l y 'screws 8. A glass tube 9 is inserted in the tubular casing 6, which is open at its front portion to render visible the contents of said tube. tubular Vcasing 6 and to the clamping members 7 and receive the slidably-'disposed valve-rods 11. These valve-rods carry inwardly-eXtending disks 12, upon the inner Guide-lugs 10 are secured to the faces of which are mounted pads 13, which are preferably formed of'leather. These pads constitute valves and serve to close both the upper and lower ends of the glass tube 9. :x

Pivoted upon the rear face of the tubular casing 6, as at 14, is an arm 15, one end of which is connepted, as at 16, to a link 17. The op osite end of said link is 'connected to one of t e valve-rods 11, as at 18. A link 19 isconnected at 20 to the other valvefrod 11 'and at 21 to the arm `15. A raise-lug 22 coacts with 4an inclined lug 23, carried by s ring-detent 24, to hold the Vvalve-rods at t eir ,limit of movement. Plates 25, having suitablenumbersthereon, are arranged adf jaeentthe tube 9 and serve as a gage to indicate the height of the various liquids con- 1 tained in said tube. A cord or other flexible connection 26 is secured, as at 27, to the free end 4of the lever 15 and passes through an eyelet 28' to the upper end of the pole. v

The operation of the device is as follows: Assuming the device to be in the position illustrated in Fig. ,1, With the top and bottom orifices of the glass tube open, the ga e is inserted in the tank the contents of which it is desired to measure. As the ole, with the glass tube, passes through the different strata of ingredients in the tank a quantity of oil is first encountered and taken into the lass, then a quantity of the sediment which oats between theoil and water, and finally a uantity of water passes into 4the tube. l' henthe lower disk 12strikes the bottom of the tank, the upper andlower valves may be; When it,

closed by pressure upon the pole.

is desired to thus close the valves, sufficient' v pressure 'is applied to the pole to overcome the-spring-detent-24. The glass tube then is forced down'upon the lower valve-pad ,13. This movement of the tube withrelation to the lower valve-rod 11 rocks arm 15 upon its pivotv and closesl the other valve simultane-v ously with the closure of the lower valve. it is not desired to lower the gage entirely to the bottom of the tank, but it is desired to close the valves when the gage is but part the Way down-in said tank, the'arm 15 may be rocked upon its pivotal point by tilting upon. the cord 26, winch movement of the arm 15 roo will, it is apparent, close the upper and lower valves simu taneously'.

From the foregoing description will be 'seen' that simple and efficient means are herein provided for accurately determining Iic the condition 0i" the' contents of an oil-tank at any point between the surface of the liquid contained in said tank end the bottom of the tank.

While the elements herein shown sind den scribed are welladapted to serve the purpose for which they are intended, if is to be understood that my invention is not limited to the precise construction set forth, vbuit includes within its purview such changes as may be made within the scope of the appended claims.

Having described my invention, what I claim is- 1. In a device of the character described,

the combination with a pole, of an openended tube carried b v said pole7 a valve lo'- cated at each end of said tube, means for closi mense ing both of said valves When pressure is ap.-

plled to Ehe pole, end means for actuating im said valves from the upper end .of th pole.

2. In as'device of the character described the combination with a pole, of an open-` from the upper end of the pole,. and a springdetent for holding seid valves at their limit'y ,of

movement. v In testlmony whereof- I affix my signapure 1n presence of two Witnesses.
