A New or Improved Anti-vibrating Arrangement for Incandescent
Gas Lighting.
I, ROBERT OGILVIE TWEEDIE, of the Firm of Tweedie, Brownlee & Co., Brass-
founders, Bellhangers, & Gasfitters, 27, Bank Street, Galashiels, of the County
of Selkirk, do hereby declare the nature of this invention to be as follows:-
I propose to hang the pendant (to which the incandescent gas burner is
attached) by a double spiralled spring to the ceiling connection.

The result being that the vibration is lost travelling over the spring. Conse-
quently the mantle is saved.

I, ROBERT OGILVIE TWEEDIE, of the Firm of Tweedie, Brownlee & Co., Brass-
founders, Bellhangers, and Gasfitters, 27, Bank Street, Galashiels, in the County
of Selkirk, 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 has for its object to prevent vibration produced by the working
of machinery or any other cause being communicated from the pendant or fitting
to the burner and thence to the mantle of incandescence gas light.
And in order that my invention may be fully understood I will now proceed
to describe the same with reference to the drawing accompanying this specifi-
cation, which shews the device or arrangement as it would appear when fitted to
a ceiling plate.
a shews the ceiling plate. 66 pieces. c metallic flexible tubing for gas
supply, fixed to the T pieces b b. e shews a spring interposed between the
T pieces b b. f shews brass screw connections for attaching the two ends of the
flexible tubing c to the T pieces bb. g shews portion of stem of pendant.
It will be seen that any vibration communicated to the ceiling plate a and
upper T piece b is absorbed by the spring e and consequently not communicated
to the pendant g and its burner fittings.
Although I have described and shewn my arrangement as applied to a ceiling

page_text: it is obvious that it may also be applied to a wall, by having the upper T piece b
connected to a wall bracket, the rest of the arrangement being the same as before
described.
This arrangement will be found particularly applicable for factories, and other
buildings in which it has not been found practicable hitherto to introduce the
incandescence gas light owing to vibration leading to the constant destruction
of the mantles.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is-
1. Fittings for incandescence gas lighting, constructed substantially as and
for the purpose set forth.
2. In fittings for incandescence lighting, interposing a spring between the fixed
portion of the fitting and that portion carrying the burner and mantle,. for the
purpose set forth.
3. In fittings for incandescence gas lighting, interposing a spring between the
fixed portion of the fitting and that portion carrying the burner and mantle, in
combination with a flexible tube for supplying the gas to the burner, for the
purpose set forth.
