I, FREDERIC HUGHES, of 20, Paget Road, West Dulwich, Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to lamps and more particularly to such as are used on
vehicles. In carrying my invention into effect, I proceed in or in about the following
manner. I provide a cylindrical outer casing open at the top and closed at the
bottom, and glazed in front or elsewhere for the emission of light. At the back of
the cylinder is an opening through which can project the end of a spring bolt, which
forms part of a lock or latch, which connects the lamp to the tube or other
arrangement provided for attaching the lamp to the vehicle. The opening at the
side of the cylinder is of sufficient size to admit of the oil reservoir being inserted
therethrough, and the lamp attended to, air holes being provided at the bottom of the
cylinder for ventilation, and a spring clip to retain the lamp in position.
Any kind
of light may be employed besides that of an oil lamp. I also provide an inner
cylinder open at the bottom and closed by a hood or equivalent at the top. This
cylinder so fits the outer one, that it can by means of a handle be rotated to a
considerable extent within the outer casing. In this inner cylinder is an opening
corresponding to that at the side of the outer cylinder, and on the opposite side is a
small hole to accommodate, in a certain position of the inner cylinder, the bolt at the
back of the outer cylinder already mentioned. By turning the inner cylinder so as
to bring the opening and that in the outer cylinder coincidently over one another,
access is provided to the interior for the lighting, trimming, or removal of the lamp,
and at the same time the back of the glazed part is closed. By giving the inner
cylinder a quarter turn, the opening in it will be removed from that in the outer case
and brought behind the glass or lens of the lamp, thus covering the opening in the
outer cylinder, and allowing the light to pass through the glass. At the same time
the bolt of the latch will have been kept back by the inner cylinder until the
hole provided in the latter for the purpose comes over the bolt which will
thereupon spring forward into the inner cylinder and keep the lamp locked until
such time as the bolt is withdrawn by a key provided for the purpose, and operating
on the lock to which the bolt belongs. I prefer to support the lamp on a rod on
which it can be rotated or from which it can be withdrawn & on which it can be
replaced so as to protect the glazed part of it. The lock in this case would be a
double throw one, one bolt locking the cylinders & the other the lamp & rod.

page_text: I, FREDERIC HUGHES, of 20, Paget Road, West Dulwich, Engineer, 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:-
My invention relates to improvements in and relating to lamps, and more
particularly to such lamps as are used on vehicles and in other positions where they
are exposed to storms. In carrying my invention into effect, I proceed in or in about
the following manner, making reference to the accompanying drawing which shows a
vertical section from back to front. I provide a cylindrical outer casing a open at
the top b and closed at the bottom c and glazed in the front d or elsewhere for the
emission of light. At the back of the cylinder is an opening e through which can
project a spring bolt forming part of a lock or catch f which connects the lamp to the
tube or other arrangement provided for attaching the lamp to the vehicle or
elsewhere. At the side of the cylinder is an opening h of sufficient size to admit of
the lamp i being inserted therethrough and attended to as and when required, air
holes being provided at the bottom of a for ventilation, and a spring clip or ledge k
to retain the lamp in position. Any kind of light may be employed besides that of
an oil lamp. I also provide an inner cylinder open at the bottom m and covered at
τ
the top by a hood or equivalent n. The cylinder so fits the cylinder a, that it can
by a handle o be rotated to a considerable extent within a. In is an opening p
extending upwards to above the top of d. Opposite p is a small hole q to accommodate
in a certain position of the bolt at the back of a as already mentioned. By
withdrawing the bolt from e and q and turning so as to bring the openings p and h
over one another, access may be had to the interior of the lamp, the back of the tube
carrying being covered by a portion of the cylinder Z. Then by giving a quarter
turn, the opening p will be removed from behind and brought behind the tube
carrying d, thus covering the opening h and allowing the light to pass out through d.
At the same time the bolt of the lock f will have been kept back by until q comes
over the bolt of f, when it will spring forward into and keep the lamp locked until
such time as the bolt is withdrawn. I prefer to support the lamp on a rod 7 on which
it can be rotated, or from which it can be withdrawn, and on which it can be replaced
so as to protect the glazed part of it. The lock in this case would be a double throw
one, one bolt locking the cylinders a and b, and the other locking the lamp to r.
Such a lock is shown in the drawing at f, the bolt 8 being the one for a and I, and
the other t for keeping it (the lamp) on r. The bolts are "shot" by the springs u
and have in them notches 8 and t¹ respectively. A spindle passes through the
lock and has on it the lug w. When the spindle is turned (in the direction of the
arrow on the drawing) by the handle x, the bolt t is withdrawn from the hole y in r,
and the lamp can be withdrawn altogether from r or turned thereon so that the bolt t
can enter any other hole therein. By continuing the movement of x, the bolt 8 is
withdrawn from q, thus allowing to be rotated so as to attend to the lamp. On
turning the reverse way, s again enters e and q and locks a and together. A
separate key might be used instead of v, w, x.
l
I do not confine inyself to the precise shapes relative proportions or disposition of
the various parts, as shown on the accompanying drawing, or mentioned in the above
specification, as any or all of them may be considerably varied without departure from
the spirit of my invention.

page_text: Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I
claim is :-
CLAIMS.
1. Lamps consisting essentially of two cylinders revolvable within one another,
the outer one having a lens or glass covered opening for the emission of light, and
the inner one having a hooded or covered top, each cylinder having also an opening
suitably situated so that they (the openings) may, by a partial rotation of the inner
cylinder be brought coincidently over one another to allow of access being had to the
interior of the cylinder, and to the oil lamp or other source of light therein, the
opening in the outer cylinder being coverable on partially rotating the inner cylinder,
and the two cylinders being kept in this position by one bolt of a lock provided
behind the outer cylinder, a second bolt of the lock retaining the lamp in position on
a rod attached to the vehicle or elsewhere, the said lock being operated by a handle
or key, the whole substantially as described in the above specification and exemplified
in the accompanying drawing.
2. The improvements in and in connection with lamps, the said improvements
being provided for and operating substantially as described in the above specification,
and exemplified in the accompanying drawing.
