Improvements in Automatic Ejectors or Feeders for use in connection
with Disinfecting Apparatus or other purposes.
A communication by WILLIAM BARNUM HOLLINGSHEAD, of Bronxville, in the
County of Westchester and State of New York, United States of America,
Electro Metallurgist.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors of 6 Lord Street, Liverpool and 6, Bank Street, Manchester
both in the County of Lancaster and 323 High Holborn in the County of
Middlesex, Civil Engineer do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to an automatic ejector, or feeder for use in connection
with disinfecting apparatus and soda dispensing fountains, or as a feeder of liquid
hydro-carbons for enriching combustible gas for illuminating purposes.
In the accompanying drawing
Figure 1 is a longitudinal sectional view of the ejector proper, as provided
with a coupling for connecting same with a pipe or other device, and
Fig. 2 a side view of the ejector in connection with a disinfectant vessel and
water-pipe.
This invention consists of two tubes of different diameters, the smaller tube A,
located within the larger tube B, and the annular space between the tubes closed,
at one end, as shown at c.
The outer-tube B, is provided near the end c, with one or more perforations, or
slots and to provide for securing the device to a pipe, or other article, the said
outer-pipe B has an annular collar, formed thereon, so that an internally threaded
coupling-sleeve G may fit over,
and against same, when made to engage oue of the
threaded ends of a thimble h, the opposite end of which is adapted to fit a screw-
sucket formed in the side of a water pipe, so that the perforated part of the outer
pipe shall project within the water pipe, as shown in Figure 2.
The ejector-pipes are preferably curved, or bent as shown in the drawings, and
the inner-pipe A is made somewhat longer than the outer pipe, the additional
length extending beyond the open end of the outer pipe, as indicated at i, in
Figure 1.
For disinfecting purposes the open ends of the ejector pipes are made to pass
through an opening in the cap K, of a vessel 1, which is adapted to contain the
liquid, or disinfecting-solution. The smallest pipe projecting some distance into
the vessel, and the outer pipe merely passing through the cap, in which position
it is soldered, or otherwise secured.
If the ejector is maintained in an upright position, the liquid or disinfecting
solution is forced out of the reservoir through the inner tube, upon the introduction
of air, or other fluid under pressure.
When the ejector is attached to a pipe through which flows water, or other fluid,
the resistance of the end extending into the pipe, causes a portion of the fluid to
be forced through the perforations, or slots in the outer-tube and through said tube
into the reservoir forcing out an equal quantity of disinfecting fluid, through the
inner-tube into the liquid flowing through the pipe to which it is attached.
If the reservoir is inverted, the opposite action is attained, i.e., the fluid of
the pipe, passes into the reservoir through the inner-tube forcing the disinfecting
liquid outwardly through the outer tube and perforations or slots thereof.

page_text: For use in connection with soda-dispensing fountains the syrup-receptacles should
be arranged on a turn-table, each receptacle being provided with an ejector, as
above described, so that the outer ends of the ejectors may alternately be brought
under the soda-jet of the fountain, and syrup desired be discharged, with the soda,
into a glass or other vessel.
When used in connection with hydrocarbon-burners the hydrocarbon is ejected,
by this device, into compressed air or steam by pressure exerted by resistance of
said fluid upon the ejector point, and slot or opening in the outer tube thereof,
thereby forcing the hydrocarbon through the inner-tube into the pipe to which the
ejector is attached, to be carried by the fluid passing through said pipe. This
ejector is also adapted for use in connection with atomizers and other articles not
necessary herein to mention.
My correspondent does not desire to confine himself to any special form of
opening in the outer tube of ejector, but believes a transverse slot, as shown in the
drawings, the best form for same.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent I declare that what I claim is:
1st. An automatic fluid ejector or feeder, consisting of two tubes of different
diameters, the smallest tube located within the other, the annular space between
the tubes closed at one end, and the exterior tube provided at or near said end
with one or more transverse slots, substantially as and for the purpose set forth.
2nd. An automatic fluid ejector or feeder, consisting of two tubes of different
diameters, one within the other, the said tubes connected at one end so as to close
the annular space between same, at said end, the outer pipe provided near its
closed end with one or more openings, or slots, and at a short distance from same,
with an annular collar, as described in combination with an internally threaded
coupling ring, and an externally threaded sleeve, whereby the device is adapted to
be secured to any desired object, substantially as and for the purpose specified.
Dated this 4th day of December 1893.
