I WILLIAM HOWES of Hughenden Augusta Road Moseley in the County of
Worcester Manager of Works do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN CARRIAGE LAMPS" to be as follows:-
My invention consists principally of the improvements herein after described in
connecting the combined candle tube and nozzle of carriage lamps to and discon-
necting it from the body of the lamp and for fastening the carriage lamp to the
lamp iron fixed on the carriage.
My arrangement for connecting the candle tube to the lamp may be used
separately from my arrangement for fastening the lamp to the lamp iron or the
two arrangements may be used in combination in the same lamp.
For convenience of description I will describe the two arrangements combined
in the same lamp.
I make on the side of the candle tube below the nozzle a longitudinal rib in the
outer face of which a cross notch or depression is made. At the extreme top of the
rib and in the inner face thereof is a smaller notch or depression with which a stud
on the nozzle of the candle tube can be engaged by a partial rotation of the said
nozzle. The bottom of the lamp body is provided with a central opening through
which the upper part of the combined candle tube and nozzle is passed into the
interior of the lamp a slot on one side of the said central opening receiving the rib
on the candle tube and preventing the rotation of the latter. The candle tube
when passed to its place in the bottom of the lamp body is connected thereto by a
broad flat sliding bolt working in the bottom of the lamp body and parallel
thereto. When the sliding bolt is pushed inwards its inner edge takes into the
cross notch or depression in the rib on the candle tube and fixes the said candle
tube very securely to the lamp body. When the sliding bolt is in its withdrawn
position for unfastening the candle tube the handle end of the said bolt projects
from the lamp body and prevents the closing of the lamp door and thus indicates
that the candle tube is unfastened.
"
The sliding bolt described also effects the fastening of the lamp to the lamp iron
fixed on the carriage For this purpose the end of the lamp iron" is expanded
into a flat slightly tapering plate. On the inner face of the said plate and near its
junction with the "iron is a flat rib or projection. In the back of the lamp body
"

page_text: is a pocket for receiving the flat tapering plate of the lamp iron and also a recess
for receiving the flat rib or projection on the said plate. When the lamp is
depressed onto the fixed lamp iron the pocket at the back of the lamp passes onto
the flat plate of the iron and the recess onto the flat rib the lamp is thereby pre-
vented from turning on the lamp iron. The lamp is then fastened to the lamp
iron by pushing inwards the sliding bolt hereinbefore described. When pushed
inwards the outer edge of the bolt engages under the rib on the plate of the lamp
iron and thereby prevents the lamp being lifted from the said iron.
In order to steady the motion of the sliding bolt and hold it firmly in its shot
position I prefer to apply to its upper face a flat spring which spring on shooting
the bolt is compressed against the rib on the lamp iron.

I WILLIAM HOWES of Hughenden, Augusta Road, Moseley in the County of
Worcester Manager of Works do hereby declare the nature of 'my Invention and in
what manner the same is to be performed to be particularly described and
ascertained in and' by the following statement:-
My invention consists principally of the improvements: herein after described in
connecting the combined candle tube. and nozzle: of carriage lamps, to and. dis-
connecting it from the body of the lamp and for fastening the carriage. lamp to the
lamp iron fixed on the carriage.
My arrangement for connecting the, candle. tube to the lamp may be used
separately frou my arrangenrent. for fastening; the. lamp to. the lamp iron; or, the
two arrangements may, be used in combination.in the same lamp.
For convenience, of description I will, describe the two: arrangements.combined
in the same lamp.
I make on the side of the candle tube, below the nozzle a: longitudinal rib in the
outer face of which a cross notch or depression is. made.. Ab.the extreme top of the
rib and in the inner, face: thereof is a. smaller notch, or depression, with which a stud
on the nozzle of the candle. tube can be engaged. by. a. partial, rotation of the said
nozzle.. The bottom of the, lain, body, is provided with a central opening through
which the upper part. of the combined. candle tube and nozzle is passed into the
interior of the lamp, a slot: on one side of the said central opening receiving the rib
on the candle tube and preventing, the rotation of the: latter. The candle tube
wheni passed to its place in, the bottom of the lamp body, is. connected, thereto by a
broad flat sliding, bolt working in the bottom of the: lamp. body, and parallel
thereto. When the, sliding bolt is. pushed inwards. its inner edge. takes into the
cross notch or depression. in the rib, on, the, candle tube, and fixes the said candle
tube very securely to the. lamp body. When, the sliding, balt.is in its withdrawn
position, for unfastening, the candle tube, the handle. end of the said. bolt projects
from the lamp body, and prevents the closing, of the. lamp, door and thus indicates
that, the candle tube.is unfastened..
The sliding bolt described, also effects.the fastening of the lamp to the lamp. iron
fixed on the carriage. For this purpose. the end. of the lamp iron is expanded into
a flat slightly tapering plate: On, the inner face, of the said. plate and near its
junction with the iron, is.a. flatcrib or projection. In. the back of the lamp body is
a pocket for receiving, the; flat tapering plate: of the lamp iron and also a. recess for
receiving the flat: rib, or projection on. the said plate. When the lamp is depressed
onto the fixed lamp iron; the pocket. at, the back of the lamp passes onto the flat
plate of the iron and the recess; onto the. flat rib;, the. lamp. is thereby prevented
from turning on the-lamp-iron..
The lamp is then fastened to the lamp iron. by pushing, inwards, the sliding bolt
herein before described.
When pushed, inwards the. outer edge. of the bolt engages, under the rib. on
the plate of the. lamp iron. and thereby prevents the lamp being lifted from the
said iron

In order to steady the motion of the sliding bolt and hold it firmly in its shot
position I prefer to apply to its upper face a flat spring which spring on shooting
the bolt is compressed against the rib on the lamp iron.
Figure 1 of the accompanying Drawings represents partly in elevation and
partly in vertical section a carriage lamp in which the candle tube is fastened to
the lamp and the lamp fastened to the lamp iron by the use of a single sliding
bolt according to my invention; Figure 2 represents in plan partly in horizontal
section the said lamp with the sliding bolt in its shot position and Figure 3
represents the same view as Figure 2 with the sliding bolt in its withdrawn
position'; Figure 4 represents the sliding bolt and its guide detached from the
lamp; Figures 5 and 6 represent elevations of the candle' tube detached and
Figure 7 represents elevations of the lamp iron detached.
The same letters of reference indicate the same parts in Figures 1 to 7.
In
a is the candle tube and b is the nozzle of the same; c is a longitudinal rib on
the candle tube, the said rib having in it two cross notches or depressions de.
the lower notch d the sliding bolt f working on the bottom of the lamp body takes
to fasten the candle tube to the lamp and in the upper notch e a study on the
nozzle b takes for fastening the nozzle to the candle tube, the said stud g being
engaged with and disengaged from the notch c by a partial rotation of the nozzle;
h is a slot on one side of the central opening in the lamp body for receiving the
rib c on the candle tube a; i is the lamp iron having at its top the flat tapering
plate is a rib near the bottom of the plate for the locking bolt f to engage
under. In the back of the lamp body is a pocket k for taking upon the plate
of the lamp iron and in the said back of the lamp body is a slot 7 for taking upon
the said rib . The sliding bolt f is made so wide that its opposite edges may
engage both with the candle tube and lamp iron. The back end of the sliding
bolt f carries the tail piece m which enters the fixed guide n on the bottom of the
body of the lamp and the front end of the said bolt carries the handle n² by which
it is worked, the flat part of the handle end when the bolt is pushed home sliding
in the guide p. The handle n* when the bolt is in its withdrawn position prevents
the door g of the lamp being closed. On the upper face of the bolt is a spring r
(see Figure 4). The bolt f being in the withdrawn position Figure 3, the lamp
body is depressed onto the plate of the fixed lamp iron i, the pocket k taking
upon the said plate and the rib is taking into the slot 7 and protruding into the
body of the lamp. The candle tube a having been passed into its place in the
hody of the lamp the sliding bolt f is pushed inwards. By the pushing inwards of
the bolt one of its edges takes into the cross notch d in the rib c on the candle
tube a and the opposite edge of the bolt engages under the rib on the plate i³ of
the lamp iron as represented in Figures 1 and 2. The candle tube a is thereby
fastened to the body of the lamp and the lamp fastened to the lamp iron by the
same sliding bolt. When the sliding bolt is shot or pushed inwards the flat
spring passes under the rib and is compressed. The motion of the bolt is
thereby steadied and the bolt held firmly in its shot position. Figure 8 represents
in elevation partly in vertical section a carriage lamp in which the candle tube
only is fastened in its place by the sliding bolt; Figures 9 and 10 represent the
lamp in 'plan, partly in horizontal section; Figure 9 showing the bolt in its shot
position and Figure 10 the bolt in its withdrawn position; Figures 11 and 12
represent elevations of the candle tube detached and Figure 13 represents an
elevation and plan of the sliding bolt detached; a is the candle tube and b the
nozzle of the same; c is the rib on the candle tube and ff, f³ the sliding bolt.
A portion of one edge of the bolt is cut away at f³ and when the bolt is in its shot
position the edge of the said bolt near the cut away part engages under the rib c
on the candle tube instead of with a notch in the rib as before described. The
handle end of the bolt" is curved and so arranged with respect to the lamp
'door q' that the closing of the said door presses inwards or shoots the bolt and
fastens the candle tube in its place. The sliding bolt works in the guides n, n.

page_text: When the bolt f is in its withdrawn position as represented in Figure 10 the cut
away part 3 of the bolt is coincident with the slot in the central opening through
which the rib c on the candle tube a passes so that on putting the candle tube in
its place, the said rib can rise through the said cut away part f³ in the bolt and
pass above the bolt without obstruction. By now shooting the bolt into the
position represented in Figures 8 and 9, a solid part of the bolt passes under the
rib c on the candle tube & and fastens the said candle tube to the lamp. By
withdrawing the bolt finto the position represented in Figure 10 the candle tube
is unfastened and can be withdrawn from the lamp. Should the bolt f not be shot
before shutting the lamp door q the shutting of the said door operates upon the
handle end of the said bolt and shoots it and fastens the candle tube in its
place.
Although I prefer to fasten the candle tube to the lamp by the engagement of
the sliding bolt under or with a rib or projection on the candle tube yet the bolt
may be made otherwise to engage with the candle tube so as to prevent its with-
drawal from the lamp.
Having now particularly described and ascertained the nature of my invention
and the manner in which, the same is to be performed I declare that I claim
as my invention of "Improvements in carriage lamps.
"
First. Connecting the candle tube to the carriage lamp and the lamp to the
lamp iron by means of a sliding bolt the opposite edges of the said bolt being made
to engage with the candle tube and with the lamp iron substantially in the manner
herein before described and illustrated in Figures 1. 2. 3. 4. 5. 6 and 7 of the
accompanying Drawings.
Secondly. Connecting the candle tube to the carriage lamp by means of a
sliding bolt constructed and combined with the lamp and acting substantially as
herein before described and illustrated in Figures 8, 9, 10, 11, 12 and 13 of the
accompanying Drawings.
Thirdly. Connecting the nozzle of the candle tube to the said tube by means
of a stud on the nozzle taking into a cross notch or depression in a rib on the
candle tube substantially as herein before described and illustrated in the accom-
panying Drawings.
