I SIDNEY CHARLES LEEDHAM FULLER, of. The Carriage Works Kingsmead Street,
Bath Somerset 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 this invention is to provide a better means of attaching & detaching,
Lamps of carriages & other vehicles whereby the said Lamps may be firmly &
securely fixed in position & may also be readilly detached without removing the
barrel or other parts, to effect this I use by preference a Lamp holder a part of which
is shewn in plan Fig. 1, of the accompanying drawings a portion of said Lamp
holder being cut away as at A, A to allow the Lamp to be moved horizontally into
the holder The upper surface of said holder is coned as shewn in section drawing
Fig. 2, taken through B, B, Fig. 1. The portion cut away being less in width than
the greatest diameter of the cone in Fig. 1.
I also provide a nut Fig. 3 to be affixed to base of Lamp a portion of the outer
surface of which nut is coned to fit the holder Fig. 1.
The inner surface being screwed to fit a screw Fig. 4. The screw Fig. 4, is of
greater length than the thickness of holder, Fig. 2.
On the base of the screw is collar C, Fig. 4. To this collar & screw I fix the
barrel of Lamp marked D.
The coned nut Fig. 3 being fixed to the base of Lamp & the screw & collar Fig. 4,
to the barrel of Lamp, the screw is entered into the nut & a suitable stop provided to
prevent its being removed a sufficient space being allowed between the edge of the
coned nut & collar C to allow the screw Fig. 4, to be passed into the Lamp holder
Fig. 1, through the space A, A. The coned nut attached to Lamp is then dropped
into the corresponding bearing in the holder and the screw attached to barrel
tightened up until the collar, C, comes in contact with the holder, thus firmly.
securing the Lamp in position.
To detach the Lamp I unscrew the barrel until the space between the collar & the
edge of coned nut is equal to the thickness of the holder or other such distance as
may be necessary-The Lamp is then raised until the cone is clear of the aperture A, A,
& can be passed out. By this plan it is practically impossible for the Lamp to be
shaken out of the holder, should the screw become loosened.
Instead of the above plan I may make the Lamp holder Fig. 1, with the coned
surface on the under side & the corresponding cone on Fig. 4, instead of collar, C,
& place Lamp in position & secure it with the screw in the manner before described or
I may make the barrel a fixture in the Lamp & fix the cone to base of Lamp E,
Fig. 6, to fit into Lamp holder Fig. 1. A plain screw is then fixed to the barrel D

page_text: so that a nut with collar C, Fig. 5, may be used to screw up to the Lamp holder and
secure the Lamp or
I may make the collar on base of Lamp, E, & cone the under side of Lamp
holder Fig. 1, & make a corresponding cone on the nut as shewn by the dotted lines
Fig. 5, & secure the Lamp as aforesaid.
The nut Fig. 5, is provided with a stop to prevent it running off the screw when
loose or may make the Lamp holder with either or both faces coned and the said
cones may be either sunk as shewn in Fig. 2 or the reverse a corresponding cone or
cones or collar being formed on the Lamp base, E, or barrel or nut Fig. 5 as may be
necessary or I may make the Lamp holder with the faces flat or other shape & use
studs, teeth collars, washers or other means instead of coned surfaces to assist in
keeping the Lamp in position & secure the Lamp by a nut & screw either of which
inay be fixed to the Lamp in such position as may be found desirable.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is
1. The use of a Lamp holder with a portion cut away as shewn at A, A, Fig. 1,
to admit the Lamp being placed in position without detaching the barrel from the
Lamp The said Lamp holder being hereinafter described as an open Lamp holder.
2. The use of an open Lamp holder as before described with a coned surface on its
upper face in combination with a coned surface affixed to the base of lamp & a screw
& collar on the barrel of Lamp to fix the Lamp as before described.
3. The use of an open Lamp holder as before described with a coned surface on its
under side in combination with a corresponding cone & screw fixed to the barrel as
before described.
.
4. The use of an open Lamp holder as before described with a coned surface on
either its upper or lower face or both in combination with a barrel fixed to the Lamp
& corresponding nut as shewn in Fig. 5.
5. The use of an open Lamp holder with curved or other shaped surfaces in com-
bination with a fixed barrel & nut similar to Fig. 5, or a screw & collar fixed to
barrel & a nut fixed to base of Lamp similar to that before described.
6. The use of an open Lamp holder in combination with Lamp fittings provided
with one or more, cones, studs, teeth, collars, washers or other means to assist in
keeping the Lamp in position, said Lamp being secured by a nut & screw either of
which is attached to such part of Lamp as may be found desirable.
7. The use of either of the above combinations in conjunction with a stop move-
able or otherwise applied to the screw, nut, barrel or other portion of Lamp to prevent
the moveable part from coming detached.
