Figure 6 is a view of a hollow perforated ball comprised in the improvement―
nn being the perforations
Figure 7 is a section on the line 6, 6, in Figure 6
Similar letters of reference designate corresponding parts in all figures.
The abutting ends P, P¹ of the gas outlet pipe are secured together by any
appropiate means for instance by a coupling sleeve D, which bears against a
collar upon the pipe P, and engages a screw thread on the pipe P1; the opening
through the outlet pipe may be closed by a perforated plate Q, the opening O
through which is of the same area as the cross section of the outlet pipe on the
test meter.
To preserve some slight degree of back pressure the opening 0 is closed by a
valve V, opening upward or in the direction of flow of the gas
G is a shell fitted to the interior of the pipe P It may be formed integral with
the plate or fixedly secured thereto.
Freely movable within the interior of the cylindrical shell G is a hollow ball E
formed of perforated material and designed to freely move lengthwise of the
shell G as well as revolve therein At the upper extremity of this shell Gare
cross wires W W, which prevent the ball from passing out of the shell entirely
or any other suitable means may be adopted for this purpose
An interior concentric shell S also perforated extends upward a short distance
from the upper surface of the plate thus preventang any interference by the
ball E with the operation of the valve V, the ball resting upon the upper edge
of the shell S when the former is at its lowest point This shell S 18 not only open
on its top but is plentifully supplied with perforations n¹ n¹ as well
The operation and purpose of the device may be readily appreciated.
Gas passing upward from the meter issues through the opening o and if of
sufficient pressure raises the ball E, an amount dependent upon the pressure of
the gas.

page_text: During the passage of the gas the ball is constantly turning, as result securing
a uniform and thorough incorporation and mixture of the gas ingredient, a brighter
and more satisfactory light will be obtained, accompanied by an economy in the
consumption of gas.
Having particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim
is.
1 In a gas regulator and economizer the combination with a tubular shell, of
hollow perforated ball freely movable, both 10tarially and lengthwise therein,
substantially as specified
2 In a gas regulator and economizer the combination of an outer shell, an
inner concentric perforated shell and a ball movable freely in the former shell,
substantially as specified
3. In a gas regulator and economizer, the combination of an outer shell, an inner
concentrio perforated shell and a hollow perforated ball, substantially as specified
4. In a gas regulator and economizer the combination of an outer shell, an inner
concentric perforated shell, a hollow perforated ball, and a valve situated at the
bottom of said inner shell, substantially as specified.
