Complete Specification Left, 8th Sept., 1893-Accepted, 14th Oct., 1893
PROVISIONAL SPECIFICATION.
Improvements in Carriage Lamps and Holders therefor.
I, ADOLPH HEINRICH WITTER of 56 Langereihe, St. Pauli, Hamburg,
Germany, Butcher, do hereby declare the nature of this invention to be as
follows:-
According to this invention the outer surface of the usual socket or candle
container is not wholly smooth as heretofore but is for a part of its length provided
with screw threads, and the inner surface of the holder is correspondingly screw
threaded.
The arrangement is shewn in the annexed drawing in which a is the holder and b
the lamp socket, the latter being shewn screwed into position.
The advantage of this arrangement is that the lamp is more firmly held in
position than is the case with ordinary holders.
To facilitate the adjustment of the lamp in the holders there is interposed
between the two an india rubber ring c which at the same time serves to intercept
or deaden the shocks sustained by the vehicle, so that the lamp is effectively
protected from injury.
Dated this 3rd day of August 1893.

COMPLETE SPECIFICATION.
Improvements in Carriage Lamps and Holders therefor.
I, ADOLPH HEINRICH WITTER, of 56 Langereihe, St. Pauli, Hamburg,
Germany, Butcher, 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 :—
According to this invention the outer surface of the usual socket or candle
container of a carriage lamp instead of being made smooth throughout its length as
heretofore, is for a part of its length provided with a screw thread, and the inner
surface of the lamp holder is correspondingly screw-threaded, so that the one can be
screwed into the other.
This construction of lamp socket and holder therefore is shown partly in elevation
and partly in section in the drawing filed with my Provisional Specification, and
wherein a is the holder the tubular sleeve portion of which is formed with an
internal screw thread, and 6 the candle socket of the lamp the upper portion of which
is formed with an external screw thread adapted to screw into the holder as shown.
By the construction described, the lamp can be more firmly held in position than
in the case of lamp the candle sockets of which merely slip into a holder formed
with a plain hole.
To facilitate the proper adjustment of the lamp in the holder there is interposed
between the enlarged upper end of the candle socket and the upper end of the
sleeve portion of the holder, a ring c of elastic material such as india rubber,
which, at the same time serves to lessen or prevent the transmission of shocks,
sustained by the vehicle, to the lamp, so as to effectively protect the latter from
iniury.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A carriage lamp having an externally screw-threaded candle socket or
container, and a lamp-holder having an internally screw-threaded sleeve into which
the said socket or container can be screwed substantially as herein described for
the purpose specified.
2. My improved carriage lamp and lamp holder with interposed ring of elastic
material substantially as described and shown for the purposes specified.
