UNITED STATES PATENT OFFICE
JAMES W. IOBBS, OF BURKBURNETT, TEXAS.
VACUUM-REGULATOR FOR OIL-PUMPS.1,259,235.
Specification of Letters Patent.
Patented Mar. 12, 1918.
Application filed October 18, 1916. Serial No. 126,390.
To all whom it may concern:
Be it known that I. JAMES W. HOBEs, a
citizen of the United States, residing at
Burkburnett, in the county of Wichita and
5 State of Texas, have invented certain new
and useful Improvements in Vacuum-Regu-
lators for Oil-Pumps, of which the follow-
ing is a specification, reference being had to
the accompanying drawings.
10 This invention relates to an improved
vacuum regulator or cut-off for oil pumps
and has for its primary object to provide
a simple and effective device whereby the
body of oil in the gas separating tank may
15 be maintained at a predetermined level and
possibility of the vacuum pulling the oil over
the top of the tank obviated.
It is another object of the invention to
provide a very simply constructed and op-
20 erated automatic cut-off valve in the vacuum
of the pipe line to the pump.
It is a further general object of my inven-
tion to improve and simplify devices em-
ployed for the above purpose, render the
25 same positive and reliable in operation, and
capable of manufacture at relatively small
cost.
In the accompanying drawing, I have
illustrated a sectional diagrammatic view
30 showing my improved controlling or regu-
lating device as arranged in the vacuum pipe
line.
Referring in detail to said drawing, 5
designates a suitably constructed tank into
35 which the oil is being pumped from the well.
An overflow or outlet pipe 6 is connected
to the bottom of said tank having a check
valve 7 arranged therein.
8 designates the pipe line extending from
4o the vacuum pump (not shown), said pipe
line having an elbow or offset 9 therein
which is connected by means of the L-shaped
coupling 10 to the lower end of a vertical
pipe 11. A pipe 12 connects the upper end of
15 the pipe 11 to a nipple 13 centrally project-
ing into the top of the tank 5, by means of
the T-shaped coupling 14. A pipe 15 is also
connected to said coupling and to the lower
end of a water reservoir 16.
io The coupling 10 has a horizontal, internal
valve seat 17 to receive a valve 18 fixed upon
the upper end of a stem 19. A suitable
bracket or support 20 is fixed to the pipe 11
and, upon the same, an angular lever 21 is
5 pivoted adjacent one of its ends, as at 22.This end of the lever is extended beyond the
pivot and. its extremity disposed in a hori-
zontal plane to engage and support the
valve stem 19, as indicated at 23. The other
end portion of-the lever 21 is angularly ex- 60
tended downwardly into the upper end of
the reservoir 16 and a float 24 is fixed
thereto.
In the operation of the apparatus, the
reservoir 16 is filled with water so as to raise 65
the float 24 and permit the valve 18 to re-
main in open position. The oil is supplied
to the tank 5 by the pumps at the wells (not
shown). The vacuum is created in the op-
eration of the pump through the pipes 8, 11, 70
12, 13 and 15, and this vacuum holds the oil
in the gas separating tank 5 at a certain
predetermined level. The vacuum is regu-
lated so that it is never sufficiently great to
pull the oil into the vacuum pipe lines. 75
Thus, when the oil reaches this predeter-
mined level, the weight of the oil in the tank
5 is greater than can be lifted by the vacuum
so that the oil will flow by gravity through
the overflow pipe 6 while the vacuum takes 80
off the gas collecting in the upper portion
of the tank 5. When the oil gets above this
level, the vacuum through the pipe 15 with-
draws the water from the reservoir 16 so
that the float 24 gradually lowers therein 85
and the end 23 of the lever 21 raises the
valve 18 against the seat 17, thus cutting off
the vacuum from the pump so that the ex-
cess oil in the tank 5 will pass out through
the overflow pipe 6 into a suitable storage 90
tank. In this manner, it will be seen that
the vacuum is automatically regulated or
controlled so that the oil in the tank 5 can
never rise to any great extent above a pre-
determined level or be drawn through the 95
top of the tank by the vacuum.
From the foregoing description, taken in
connection with the accompanying drawing,
the construction, manner of operation and
several advantages of the invention will be 100
clearly and fully understood. The device,
while exceedingly simple, has been found to
be very reliable and positive in its action.
It is, of course, manifest that various other
relative arrangements of the tank 5 and res- 105
ervoir 16, together with the pipe line con-
nections, may be adopted. The several com-
ponent parts of the device are also suscepti-
ble of considerable modification therein and
I, therefore, reserve the privilege of adopt- 110
