PROVISIONAL SPECIFICATION.
Improvements in or connected with Carriage Lamps.
We ROBERT JAMES DOBBS, of 10 Ryland Street, in the City of Birmingham,
Coach Ironmonger, and GEORGE Moss, and JOSEPH HOWARD HETHERINGTON,
trading as J. H. Hetherington & Company of Constitution Hill, in the City of
Birmingham Lamp Manufacturers, do hereby declare the nature of this invention
to be as follows :-
This invention has reference to the method and arrangement by which the
handles of carriage lamps are secured to the sockets of such lamps, and also by
which the said lamps themselves are secured to their lamp irons, and in which both
are secured simultaneously.
In carrying out our invention we proceed as follows:-
In the lamp iron, and upwards from its lower edge, a slot is made, which, after
ascending some little distance vertically, is then carried horizontally for a short
distance, and thence again falling vertically for a short distance only, thus forming
very much what is commonly known as a bayonet fastening slot.
Again. At the lower end of the lamp socket, that is, that part which fits into the
said iron, a coincident slot is formed, so that when the lamp is placed in the iron,
such two slots come exactly opposite to each other.
Further. Upon the handle of the lamp is now provided an outstanding pin,
which, (when the handle is passed up into position) travels up and along and down
the said slots, by first a vertical, then a horizontal and finally a downward travel,
thus securing the handle to its lamp and at the same time the lamp to the iron.
Of course it will be seen that the exterior surface of the handle needs only to be
quite plain (except the pin) that is, no projections, collars or recesses, which at
present are so common in fastenings for this purpose. Also, that the handle is
equally fastenable to the lamp independent of the lamp iron, by reason of the slot
in the lamp socket itself.
The external of the lamp socket and the internal of the lamp iron may be oval,
or round.

COMPLETE SPECIFICATION.
Improvements in or connected with Carriage Lamps.
We ROBERT JAMES DOBBS, of 10 Ryland Street, in the City of Birmingham,
Coach Ironmonger, and GEORGE Moss, and JOSEPH HOWARD HETHERINGTON,
trading as J. H. Hetherington & Company, of Constitution Hill, in the City of
Birmingham, Lamp Manufacturers 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 reference to the method and arrangement by which the
handles of carriage lamps are secured to the sockets of such lamps, and also by
which the said lamps themselves are secured to their lamp irons, and in which both
are secured simultaneously.
In order to more clearly explain this our invention we have appended hereunto
an illustrative sheet of drawings upon which are figures and numbers of reference,
similar numbers referring throughout the several views to the same thing or part.

page_text: Fig. 1, is a rear view of a carriage lamp upon which is fitted this our invention.
Fig. 2, is a detached part elevation of the socket or lower portion of the lamp
showing the slot therein.
Fig. 3, is a detached view of part of the lamp iron.
Figs. 4 and 5 are detailed front and side views of the handle (or candle holder)
of the lamp.
In carrying out our invention we proceed as follows:-In the lamp iron 1, and
upwards from its lower edge, a slot 2, is made, which, after ascending some little
distance vertically, is then carried horizontally at 3, for a short distance, and thence
again falling vertically at 4, for a short distance only, thus forming very much
what is commonly known as a bayonet fastening slot, see Figs. 1 and 3.
Again. At the lower end of the lamp socket 5, that is, that part which fits into
the said iron 1, a coincident slot 6, 7 & 8 is formed, so that when the lamp is placed
in the iron, see Fig. 1, such two slots come exactly opposite and agree with each
other.
Further. Upon the handle 9, of the lamp is now provided an outstanding pin 10,
which, (when the handle is passed up into position) travels up and along and down
the said slots, by first a vertical, then a horizontal, and finally a downward travel,
thus securing the handle to its lamp and at the same time the lamp to the iron, as
shown in Fig. 1.
Of course it will be seen that the exterior surface of the handle needs only to be
quite plain (except the pin) that is, no projections, collars or recesses, which at
present are so common in fastenings for this purpose. Also, that the handle is
equally fastenable to the lamp independent of the lamp iron, by reason of the slot
in the lamp socket itself.
The external of the lamp socket and the internal of the lamp iron may be oval,
or round, as may be desired.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
In carriage lamps, the securing of the candle tube or handle, with the sockets,
and the said sockets with the lamp iron by the combination with the projecting
peg 10, of the slots 2, 3, 4, and 6, 7, 8, after the manner described and shown.
