PROVISIONAL SPECIFICATION.
Improvements in or connected with Lamps for Velocipedes and
other Vehicles.
I, WALTER HEWITT of 3 Warwick Row, Coventry, in the County of
Warwick, Commercial Traveller, do hereby declare the nature of this invention to
be as follows:-
:―
The object of my invention is to entirely obviate or greatly lessen the vibration
or motion communicated to lamps when the latter are carried from place to place.
or are fitted upon velocipedes, carriages, or other vehicles, locomotives or the like.
To this end I apply to the lamp a pneumatic or elastic inflated cushion, so fitted
and arranged as to intervene between the lamp and the fixed or other part by or
upon which the lamp is carried. Such a pneumatic or inflated cushion may be fitted
and form an integral part of the lamp, or may be so constructed or arranged as to
form a separate or separable part of the lamp, capable of being attached thereto
when required, and the pneumatic holder may entirely or partially replace the
usual springs commonly employed, or be used as an addition thereto.
According to my invention, and as applied to a lamp such as used on velocipedes,
I provide an annular tube of india rubber, which I locate within a case fitted at
the back of the lamp. At the base of the case there is a suitable aperture to take
the prong of the usual lamp bracket which passes thereby into the annulus of the
elastic tube. This elastic tube should be inflated either before or after the
insertion of the prong of the bracket. I generally provide a lining say of india'
rubber in the interior of the annulus of the tube in order that the lamp bracket.
should not injure same. The annular tube is fitted with a valve of suitable con-
struction which may extend through the containing case and by which the annular
tube may be inflated; when thus inflated the vibrations of the carrying bracket.
are insulated from the lamp in a most effectual manner.
Having thus described in some detail; one practical adaptation of my invention,
it will be readily understood that its constructional application may be greatly.
varied and suited to the particular lamps to which it may be applied.
I generally prefer to insert the carrying bracket and afterwards inflate the
pneumatic pad by means say of an air pump such as commonly employed for cycle
tyres, and the bracket is thereby tightly gripped and the lamp does not in most
cases require screws or the like to retain it in position.
I do not limit myself to the shape of the air chamber or ball, and the case for
same may be formed of metal, or of cotton, linen, or other substance.
By my invention lamps are practically carried on an air cushion, rendered thereby
free from vibration, will burn better and are not so liable to be jolted out as is now.

1, WALTER HEWITT, of 3 Warwick Row, Coventry, in the County of
Warwick Commercial. Traveller, 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 :-
The object of my invention is to entirely obviate, or greatly lessen, the vibration
or motion communicated to lamps, when. the latter are carried from place to place,
or are fitted upon velocipedes, carriages, or other vehicles, locomotives or the
like.

To this end I apply to the lamp a pneumatic or elastic.inflated cushion, so fitted.
and arranged as to intervene between.. the lamp, and the fixed, or other part. by,
or upon which, the lamp is carried. Such a pneumatic or inflated cushion be

thereto when required, and the pneumatic holder may entirely, or partially, replace.
the usual springs commonly employed, or be used as an addition thereto..
.
In order that my invention, may be readily understood,. I will describe some.
examples of its application: with reference to.the accompanying drawings..
Fig. 1 is a sectional side elevation. shewing my invention as applied to a .. lamp,
supported by an ordinary lamp bracket, and. Fig. 2.is a sectional plan.of.same..
Fig. 3 is a sectional side elevation, shewing an application to a.spherical for. ball.
ended bracket.
Fig. 4 is a side elevation shewing, a pneumatic, support,, where the latter. is
detachable from the lamp.
Figs. 5 and 6. are respectively part .side elevation, and part plan,, of another
modified arrangement, and Fig. 7 shews the invention applied to supporting a lamp
of differing, construction.
used., on
According to my invention, and as applied to a lamp. L. such as.
velocipedes, with particular reference. to. Figs. 1 and..2, I provide an annular tube
of india rubber A which I looate.within a. case.B, fitted at the back of the lamp:L.
At the base of the case. B there is a suitable aperture. C, to take the prong, D,
of the usual lamp bracket D! which passes thereby into the annulus of the elastic
tube A.. This elastic tube A. should he inflated, either before, or after the insertion
of the prong of the bracket D1. I generally provide a lining. E, say of india
rubber, in the interior of the annulus.of. the tube A,,in order that the lamp
bracket prong D should not injure same. The annular tube. A. is fitted with a.
valve of suitable construction, which extends.through the containing, case B, and
by which the annular tube. A may be inflated.;; the valves may pass through the
case B. at any convenient part, thus at. Eig, the valve. F is-sbewn at the back of
the case B, while at Fig. 2 it is on one side thereof.. When the tube. A is inflated;
the vibrations of the carrying bracket. D. are, insulated, from the-lamp, in .a.most
effectual manner.
Having thus described in some detail, one practical'adaption of my invention, it
will be readily understood that tits constructional application may be varied, and
suited to the particular lamps to which it may be applied.
I generally prefer to insert the carrying bracket D', and afterwards inflate the
pneumatic pad A, by means say of an air pump, such as commonly employed for
cycle tyres, and the bracket D¹ is thereby tightly gripped, and the lamp L does
not in most cases require screws or the like to retain it in position.
I do not limit myself to the shape of the containing case B, or of the air

page_text: containing bag or tube held therein, or to inflating the air bag to secure the lamp to
its holder, as said air bag may have been previously inflated' and arranged to be
clamped by an outside shell, and so made to grip the socket piece D, or L pin;
the case B is shewn as being formed of metal, but it may be formed of other
material, and might be made either partially, or wholly flexible; thus the case B'
might be formed of leather or fabric stiffened or not as required..
Instead of the lamp bracket D beiug formed as usual with a vertical prong D,
I in some cases provide a ball or equivalent end D to bracket D' an example
of which is shewn at Fig. 3. The case B is here formed with an aperture Cat.
the back, through which the ball-end D is passed before the air tube A is inflated;
the ball D may pass into a flexible lining E, and upon the air tube A being
inflated the lamp is held in position.
As will be well understood the lamp L, may as shewn at Fig. 4, be detachable
from the case B containing the air cushion, the said lamp being either held thereto
by a hook and socket as shewn, or by any other preferred means, and the lamp
may even have usual springs as is shewn at Fig. 4, or not, as desired. It will be
obvious from the illustration that the case B may be fitted to receive any lamp as
now constructed.
In the construction shewn at Figs. 5 and 6 the case B is carried from the lamp
body L by arms B', and is divided and hinged at B, so that the air container or
tube may be conveniently inserted, the valve F projecting through an opening at
the closing-edges of the case B. B³ is a clasp or fastening of suitable construction
whereby the case B may be held closed. In the example Figs. 5 and 6 the case B
is constructed to receive an ordinary-vertical prong bracket, inserted through an
opening in the base of the case as in Fig. 1.
Sometimes this opening for the prong bracket, may be made sufficiently large,
to allow of the insertion of the air tube or container therethrough, in some cases to
allow of greater resiliency. The figures of the drawings previously described
shew types of lamps commonly used on velocipedes, but it is evident therefrom that
the air cushioning is readily applicable to lamps otherwise constructed for carriages,
and other vehicles. With reference to Fig. 7 a simple application is shewn to a
carriage lamp L having a stem L'; the stem passes through the lining E, supported
by the air tube A, in the case B, carried by the bracket piece D', from the
vehicle.
By my invention lamps are practically carried on an air cushion, rendered
thereby free from vibration, will burn better, and are not liable to be jolted out,
as is now the case with lamps as at present constructed.
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 or connected with lamps for velocipedes, and other vehicles, the combina-
tion therewith of a fixed or detachable case, formed with an aperture to receive a
prong, ball, or the like part of a carrying bracket upon the vehicle, a flexible air
tube or chamber capable of inflation, contained within the case and shaped so as
when inflated to embrace the lamp bracket, and insulate the vibratory motion of
the latter from the lamp, substantially as described.
2. The arrangement of the lamp L, the case B in connection therewith, the air,
tube A within the case B, the air valve E and the lamp bracket D' D' substantially
as described and illustrated with reference to Figs. 1 and 2 of the accompanying
drawings.
3. The arrangement substantially as described and illustrated with reference to
Fig. 3 of the accompanying drawings.
4. The arrangement wherein the case B is detachable from the lamp L, substan-
tially as and for the purposes described and illustrated with reference to Fig. 4 of
the accompanying drawings.

page_text: .5. The construction and arrangement, substantially as described and illustrated,
with reference to Figs. 5 and 6 of the accompanying drawings.
6. The case B containing the air cushion A carried by a support from the
vehicle, and adapted to hold the lamp proper, substantially as described and with
reference to Fig. 7 of the accompanying drawings.
