IMPROVEMENTS IN APPARATUS USED IN THE DISTRIBUTION OF GAB
Year: 1879

page_text: LETTERS PATENT to Charles Horsley, of Highbury New Park, in the County
of Middlesex, for the Invention of "IMPROVEMENTS IN APPARATUS USED IN
THE DISTRIBUTION OF GAB."
Sealed the 31st October 1879, and dated the 18th June 1879.
PROVISIONAL SPECIFICATION left by the said Charles Horsley at the Office
i of the Commissioners of Patents on the 18th June 1879.
CHARLES HORSLEY, of Highbury New Park, in the County of Middlesex.. "In-
PROVEMENTS IN APPARATUS USED IN THE DISTRIBUTION OF GAS."
This Invention has reference to what are technically known as syphons, receiveres,
or tarwells, and has for its object the construction of them in a more economical
manner, and at the same time ensure them from leakage.
The Invention consists, in the first place, in casting the syphon with a top which
would otherwise be its cover. This top has a concentric boss with a hole in its
centre, the hole being screwed. Into this hole is screwed a plug, in form like the
gland of a stuffing box, the upper part of it however having six sides like a hexa-
gonal nut, so as to admit of it being turned by a suitable wrench. The plug has a
hole in its centre for the reception of the suction pipe used to pump out the contents
of the syphon, and this hole may be screwed or not. If the holo is tapped with a
female thread it is only necessary to screw in the top of the descending or suction
pipe until sufficient of the male thread of the pipe is left exposed at top to be
embraced by an ordinary cap, but if the hole last mentioned is not screwed, then it
will be necessary to provide the pipe with a screwed nut both above and below the
plug or gland to retain the pipe in its place. When the pipe is fixed in the plug or
gland the latter may be dropped into the hole in the boss, and screwed down by
means of the wrench.
The Invention, in the second place, consists of a modification of the foregoing,
that is to say, the top of the syphon has a socket cast on it, a hole being left in the
centre. Into this socket a plug is dropped, the descending pipe being attached to
the plug, as before described. The junction between the plug and the socket is
made by caulking the interstice with yarn, and subsequently filling it with melted
lead. The object of using a plug in each case is to facilitate the introduction and
withdrawal of the descending or suction pipe, while the hole into which the plug
fita also serves in some cases for the removal of the core after casting.

CHARLES HORSLEY, of Highbury New Park, in the County of Middlesex. “ IM-
PROVEMENTS IN APPARATUS USED IN THE DISTRIBUTION OF GAS."
This Invention bas reference to what are technically known as syphons, receivers,
or tar-wells, and has for its object the construction of them in a more economical
manner, and at the same time ensure them from leakage.
The Invention consists, in the first place, in casting the syphon with a top which
would otherwise be its cover. This top has a concentric boss with a hole in its 1
centre, the hole being screwed. Into this hole is screwed a plug, in form like the
gland of a stuffing box, the upper part of it however having six sides like a hexa-
gonal nut, so as to admit of it being turned by a suitable wrench. The plug has a
hole in its centre for the reception of the suction pipe used to pump out the contents
of the syphon, and this hole may be screwed or not. If the hole is tapped with a 1
female thread it is only necessary to screw in the top of the descending or suction
pipe until sufficient of the male thread of the pipe is left exposed at top to be
embraced by an ordinary cap, but if the hole last mentioned is not screwed, then it
will be necessary to provide the pipe with a screwed nut both above and below the
plug or gland to retain the pipe in its place. When the pipe is fixed in the plug or 2
gland the latter may be dropped into the hole in the boss, and screwed down by
means of the wrench.
The Invention, in the second place, consists of a modification of the foregoing,
- that is to say, the top of the syphon has a socket cast on it, a hole being left in the
centre. Into this socket a plug is dropped, the descending pipe being attached to 2
the plug, as before described. The junction between the plug and the socket is
made by caulking the interstice with yarn, and subsequently filling it with melted
lead. The object of using a plug in this case is to facilitate the introduction and
withdrawal of the descending or suction pipe, while the hole into which the plug
fits also serves in some cases for the removal of the core after casting.
In order that the foregoing may be more easily understood Drawings are attached
bereto, of which the following is a description:-Fig. 1 is a plan of the syphon,
receiver, or tar-well, and Fig. 2 is a longitudinally vertical section of the same with
its appropriate suction pipe and cap.
A is the body of the receiver, formed with a spigot B at one end and a socket C 3
at the other; it may however be made with a socket or sockets at each end, or a
spigot or spigots at each end, or a socket and spigot at each end if found desirable.
D is the boss cast on the top of the syphon, and E is the hexagonal plug which
screws into it. F is the suction pipe, having a thread cut on its upper part so as to
screw into E and project above it sufficiently to be received and embraced by a cap 4
G, which is removed when the syphon requires pumping.
Apart from the advantages herein before claimed, it will be observed that from
the long and narrow shape of the syphon there is no necessity for making the exca-
vation wider to receive it than the trench ordinarily cut for the pipes with which
it is connected, neither do these syphons require the trench to be cut so deep as
for ordinary syphons. Great saving of time, trouble, and expense is consequently
ensured by the adoption of syphons made as herein described
Having now described and particularly set forth the nature of this Invention,
and the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that I do not confine or restrict myself to the precise 5
details or arrangements that I have described or referred to, as variations may be
made therefrom without deviating from the principles or main features of this

page_text: Invention, but what I consider to be novel and original and therefore claim as the
Invention secured to me by the herein-before in part recited Letters Patent is,
the construction of syphons, receivers, or tar-wells as herein described and shown on
the Drawings, and such modifications thereof as are herein described.
In witness whereof, I, the said Charles Horsley, have hereunto set my hand
and seal, this Seventeenth day of December, in the year of our Lord One
thousand eight hundred and seventy nine.
