/ Application filed January 10, 1916. Serial No. 71,374.
To all whom it may concern:
Be it known that I, WALTER citizen of the United States, residing at Humble, in the countyof Harris and State 5 of Texas, have invented certain new and useful Improvements in an Oil-Thief, of which the following is a specification.
This invention relates to new and useful improvements in an oilthief. v
The object of the invention is to provide a device of the characteri described whereby the oil in a container may be tested.
- "With the above and other objects in View the invention has paricular'relation to certain novel features of construction, opera- ,tion and arrangement of parts, an example of which is givenin this specification and illustrated in the accompanying drawings wherein: v v
Figure 1 is a side elevation of. the" device, Fig. 2 is a fragmentary side elevation thereof, Fig. 3 is a plan view thereof, Fig. 4 is a.
vertical sectional view taken on the line aa of Fig. '1, Fig. 5 is a transverse sectional view taken on the line 6-?) of Fig. 4, Fig. 6 is a sectional .view of one of the valves employed, and 7 is a sectional view of the trip weight, employed.
Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures the numeral 1 designates a substantially cylindrical casing, which is formed preferably of metal casting and is provided with the windows 2, 2 formed of. glass or other transparent material, and arranged opposite each other, through which the contents of the casing may be inspected. Threaded into the lower end of the casing is the plug 3 AQ-having the central passage way 4 whose upper end is flared'forming the seat 5' and the upper end of the casing has the cap 6 threaded thereon, which has the central passageway 7 whose upper-endis flared forming the seat 8 and threaded upon the'cap 6 is the cage 9, cylindrical in form, and whose purpose will be hereinafterset forth.
The seat 8 is normallyclosed by the ball valve 10 and the seat 5 is normally closed 0 by the valve 11, the latter of which being secured to the valve rod 12 and the former having a limited sliding engagement with said valve rod., A transverse .bar 13 is fixed in said casing and has a central orifice 14 which serves as a guide for said rod and surrounding the rod and interposed between H. KAUL, a p
the bar 13 and the valve 11 is a coiled push spring 15 through the influence of which both of said .valves are normally held against their corresponding seats. The valve 10.has a limited amount of play relative to the rod 12 so that the distance between the seats 5 and 8 may be slightly varied and yet each of the valves seat perfectly.
Threaded into thevalve 10 and extending up through the oblong slot 16, cut through the top of the cage 9, is a short rod 17, to the I projects out beyond the cage.
A hook 19 is pivoted at its lower .end to the. casing 1 and when engaged over said upper end of which the latch 18 is pivoted latch secures the rod and valves in elevated position. Projecting at right angles from the lower end of the hook is the flange 20 whose purpose will be. hereinafter set forth.
Attached to the cage 9 is a bail 21 to which a sustaining cable 22 may be secured and slidable on this cable is the spherical trip weight 23. A trip rod 24 is provided whose upper end is bent over and formed into an eye 25, through which the cable 22 passes and the lower end of this rod normally rests upon the flange 20, said rod' passing through an alined bearing in the top of the cage.
When it is desired to use the device the latch 18 is brought into right angular position relative to the-rod 12 and the-hook 19 is engaged the-reover. This will operate to 'unseat the valves 10 and 11 and to compress the spring 15-. The lower end of the rod 24 is then rested upon the flange 20 and the de-' vice is then, by the cable 22 lowered the desired distance into the 011 to be tested.
'Meanwhile the'trip weight .23 is held by the tester until the device is lowered to the exact position desired. This weight is then released and drops down along the sustaining cable until it strikes the upper end of the rod .24 and through said 'rod operates to release the hook 19 from the latch 18 and the pressure of the spring 15 then operates to' seat the valve. The casing 1 has, of course, filled with foil and when the valves are seated this oil will be retained in the device while it is being withdrawn, for the purpose of being tested, In large tanks or containers the quality of oil varies with the depth of the oil and it is therefore necessary to obtain specimens of the oil at different depths for testing purposes and it is for that purpose that the device herein described has been designed. The casing may also be equippedwith a thermometer, as 26, of any well known construction, for the purpose of also testing the temperature of the oil being tested.
What I claim is:
1. A device of the character described ineluding a receptacle having opposing inlet passageways surrounded by seats, valves normally closing said passageways, a valve 2. A device of the character described, in-
eluding a receptacle, having opposing inlet passageways surrounded by seats, valves normally closing said passageways, means connecting said valves, a resilient member in operative connection with said means and tending to hold said valves seated, a latch carried by said means, a mechanism pivoted to the device and engaging with said latch and holding the valves elevated relative to said seats, and a tripping device for disengaging said mechanism from said latch and permitting the valves to seat.
In testimony whereof I have signed. niy name to thls specification in the presence of two subscribing witnesses.
