PROVISIONAL SPECIFICATION.
Improvements in Anti-vibrating Springs for Incandescent and other
Lamps.
I, GEORGE FREDERICK SANDERS, of the Hockley Street Works, Hockley Street,
City of Birmingham, in the County of Warwick, Manufacturer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the improvements hereinafter described to anti-
vibrating springs for incandescent and other lamps such for example as gasaliers,
electroliers, and the like and has for its object to provide a means of preventing
tremour or vibration from reaching the lamp and interfering with the flame,
causing injury to the mantle. In carrying my invention into effect, when
applied to an ordinary incandescent pendant, I attach to the rose or coiling joint,
a bracket having two extending arms from which depend two rods, i.e. one on
either side. To the extreme end of the pendant or down gas pipe I attach a
similar bracket which forms part of the stuffing box; the extending arms of this
said bracket are furnished with holes through which pass loosely the two rods
aforesaid.
To the lower end of the rods I connect another bracket by the extending arms
which is furnished with a central hole through which passes the down gas pipe
which slides therein. Between the arms of this bracket and the arms of the
stuffing box bracket I place a coil spring upon cach of the depending rods thus
suspending the down gas pipe or pendant upon the springs by means of the
bracket attached to the end of the down pipe, the weight of the said pipe and
fittings depressing the springs and preventing any vibration or tremour from
reaching the burners of the lamp.
may in some cases dispense with the de-
pending rods and attach the springs to the arms of the top bracket that is to say
one is attached to each end of the ceiling joint bracket and the bracket attached
to the end of the down pipe thus suspending the pendant thereon. My said
invention may in like manner be applied to electroliers and pendants for sup-
porting oil and other lamps I do not however confine myself to the use of two
springs, I may use one in which case I may encircle it round the down pipe and
enclose the same in a metal tube, the action being the same as when two springs
are employed.

Improvements in Anti-vibrating Springs for Incandescent and other
Lamps.
I, GEORGE FREDERICK SANDERS, of the Hockley Street Works, Hockley Street,
City of Birmingham, in the County of Warwick, Manufacturer, 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 the improvements hereinafter described in anti-
vibrating springs for incandescent and other lamps such for example as gasoliers,
electroliers and the like and has for its object to provide a means of preventing
tremor or vibration from reaching the lamp and causing injury to the mantle.
In carrying my invention into effect when applied to an ordinary incandescent
pendant, I attach to the rose or ceiling joint a bracket having two extending
arms from which depend two rods i.e..one on either side. To the extreme end of
the pendant or down gas pipe I attach a similar bracket which forms part of the
stuffing-box, the extending arms of this said bracket are furnished with holes
through which pass loosely the two rods aforesaid. To the lower ends of the rods
I connect another bracket by the extending arms which is furnished with a
central hole through which passes the down gas pipe which slides therein.
Between the arms of this bracket and the arms of the stuffing box bracket I
place a coil-spring upon each of the depending rods, thus suspending the down
gas pipe or pendant upon the springs by means of the bracket attached to the
end of the down pipe, the weight of the said pipe and fittings depressing the
springs and preventing any vibration or tremor from reaching the burners and
the mantles of the lamp. My said invention may in like manner be applied to
electroliers and pendants for supporting oil and other lamps. I do not however
confine myself to the use of two springs. I may use one in which case I may
encircle it round the down pipe and enclose the same in a metal tube, the action
being the same as when two springs are employed. In order that my invention
may be more clearly understood I will describe it by reference to the accompany-
ing drawings, the same letters of reference indicating similar parts throughout.
Figures 1, 2, and 3 illustrate a front elevation, plan, and side elevation, re-
spectively, of my invention. Figure 4, is a vertical section of Figure 1. Figure
5 is a similar view as Figure 1, with the springs compressed. Figures 6, 7,
and S show modifications of my invention. A, represents a bracket attached
to the screw of the ceiling joint B. C, is the stuffing box which supports a like
bracket 1), from which depends the tubular slide E, into which fits a similar
slide 1, the two forming a telescopic slide which encloses the coil-springs G, G.
The slide F, is fixed to the bracket H, into which are screwed the guide pins I, I.
The down gas pipe or pendant K, passes through the hole J, in the bracket H,
and supports the gas lamp, the weight of which depresses the springs G, G, as
shown at Figure 5, thus preventing any vibration or tremor reaching the burner
or mantle of the lamp. The modification shown at Figure 6, illustrates the
manner in which my invention is applied to street lamps or standard lamps, the
burner being screwed to the screw B, and the mantle being attached thereto,
they are supported by the spring arranged as aforesaid instead of suspended.
In the modification shown at Figures 7 and 8, I use one spring G, which I
enclose in a telescopic slide E, and F, instead of using two springs, the action
being the same as hereinbefore described in reference to the other arrangements.

page_text: 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. The improved anti-vibrating spring for incandescent and other lamps, where-
by vibration or tremor is prevented from reaching the lamp, substantially as
described.
2. The combination with a gasolier or electrolier of the anti-vibrating spring
or springs G, the telescopic slide E, or slides E, and 1', the brackets A, D, and H,
and the guide pins I, I, arranged to operate substantially, as described and
illustrated, and for the purpose set forth.
3. The combination with an incandescent or other lamp, of the anti-vibrating
spring or springs G, the telescopic slide E or slides -E, and F, the brackets A, H,
and the guide pins I, I, whereby the burner and mantle are supported or held,
arranged to operate substantially as described and illustrated at Figure 6 and for
the purpose set forth.
