PROVISIONAL SPECIFICATION.
New Anti-vibration Spring for Use in Street Lighting by Incandescent
Gas Systems.
I, ROBERT MAYNARD GLOYNE of Woodthorpe Enys Road, Eastbourne Civil
Engineer do hereby declare the nature of this invention to be as follows:-
A spiral spring of suitable material fitted on to a copper, or other metal, flat
ring to suit lantern carriages of all makes, and finished at the top with a metal
collar fitted with setscrew or setscrews so as to firmly clasp any sized branch pipe
through which gas is conducted to street lamp burners on incandescent systems.

New Anti-vibration Spring for Use in Street Lighting by Incandescent
Gas Systems.
I ROBERT MAYNARD GLOYNE, of Woodthorpe, Enys Road, Eastbourne in the
County of Sussex, 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:-
So far as I am able to ascertain, it is the practice at present to secure incandescent
gas burners for street lamps and the like, to the branch or service pipe which is
wedged or otherwise firmly fitted within and to the usual standard or pillar, so that
vibration or jar of the said pillar or service pipe, by reason of heavy traffic or
actual collision is communicated more or less to the delicate mantle or hood
of non-volatizable fabric which is the main feature of such incandescent gas
lighting, so causing destruction of the said mantle.
"
"
Now by my present invention, I seek to obviate or decrease this vital vibration
and for this purpose, I interpose a spiral or coiled metallic spring between the
branch or service pipe and the pillar or standard in the following manner, and in
order to more clearly demonstrate my said invention, I have attached hereto a
sheet of drawings, to which I shall hereinafter refer in further describing the same.
On this sheet of drawings,
Figure 1 is a part section and elevation of an ordinary street lamp having an
incandescent gas burner and fitted with my appliance for reducing vibration.
Figure 2 is a larger view of my apparatus.
In carrying my invention into effect I provide a metal plate A, Figures 1, and 2,
having cuts or incisions B, B, B, B, to fit over or engage with the arms C, C, C, C,

page_text: Figure 1, of the carriage M, M, M, the said plate A resting on the collar L of
said carriage surrounding or fitting upon the top of cast metal pillar D. Upon
this plate A, I mount or secure a spiral spring or coil E of any convenient size or
shape carrying at its upper extremity a metal collar F. of any suitable form
calculated to fit over or on to the end of the branch or service pipe, the said
collar F being fitted with a set screw or like device H. The metal plate A has a
circular piece cut out from its centre as J or may be formed with this concentric
space therein of any convenient size. The manner of applying my invention is as
follows: The plate A carrying the coil E and the collar F, is passed over the end
of the service or branch pipe K, and the incisions B, B, B, B, made to coincide
with and fit partially around the arms C, C, C, C, Figure 1. The collar is then
slightly pressed downwardly, contracting the coil, and the set screw H driven
home so that the collar F is firmly secured to the top (or near it) of the branch K.
The usual incandescent fittings are then fixed, and it will be found that the
vibration of the standard and service pipe K, (the wedges now employed for
keeping the same rigid being no longer necessary) is absorbed, or nearly so, by
the coil E, and the life of the mantle considerably increased in duration
accordingly.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In mounting incandescent lamp fittings on street lamps and the like or on
any lamp standards exposed to vibration or shock, interposing between said
standards and their service or branch pipes, a coiled metallic spring in the manner
described and illustrated in and by the foregoing specification and the
accompanying drawings.
2. The device or apparatus for preventing or lessening the effects of vibration
in the fittings of incandescent gas burners attached to street lamps or the like
substantially as described in the foregoing specification, and as illustrated by
Figure 2 on the accompanying drawings.
