described and ascertained in and by the following statement :-
This invention relates to improvements in lamps and particularly to that class of
lamps in which the body of the lamp performs the function of a chimney.
The object of this invention is to provide in a lamp a simple and inexpensive means
for protecting lenses or highly polished reflector surfaces with which the body of
the lamp may be provided, the said protecting means preventing smoking of the
parts, and being readily detachable for the purpose of cleaning or replacement in
case of breakage, and also for the purpose of affording accessibility to all the parts
of the lamp.
The invention is illustrated by the accompanying drawings in which-
Fig. 1 is a plan view of a portion of the body of a lamp and illustrating my
invention.
Fig. 2 is a sectional view of the parts shown in Fig. 1, said section being taken
on the line 2-2, Fig. 1.
The drawings accompanying this application illustrate only the intermediate
portion of the body of a lamp, the upper and lower portions of the lamp illustrated
being removable.
A is the body of a lamp, B is a lens in the side of the said lamp, the said lens in
the lamp illustrated being carried by a front reflector D having by preference
diverging sides, as shown.
This front reflector D is by preference hinged, as at E, to one edge of a suitable
opening in the body of the lamp: F is a fastening means, in this case a spring latch,
carried by one of the parts A D, and detachably engaging the other part. By the
means described, the front portion of the lamp may be readily opened and closed.
G is a back reflector. This reflector G is by preference detachably engaged with the
interior of the body of the lamp. H is a shield for said reflector. This shield H is
detachably connected to the body of the lamp in the manner hereinafter described.
I is a shield detachably connected to the body of the lamp and adapted to protect
the front reflector and lens from the smoke or flame from the wick. In this connection
it should be stated that the flame is located substantially midway between the
shields H I. The central portion of these shields is made of glass or other suitable
transparent material, same being suitably held in a surrounding or partially surrounding
frame, as shown. J J are two inwardly projecting shoulders from the body of the
lamp A, the said reflector G being detachably held in position thereby, the opposite
edges of the said reflector being held in the angles formed by the said shoulders J J
and the adjacent inner surface of the lamp body A. The protecting shields HI are
detachably held in position by substantially corresponding means, KK being the
shoulders adapted to engage the shield H, while the shoulders L L retain the
shield 1. The glass or transparent portion of the shields H I may be of any desired
shape or thickness.
By the means described, it is manifest that every portion of lamp is readily
accessible.
In carrying out this invention, certain changes may be desirable, and it is
therefore not limited to the specific form and arrangement of the parts herein shown
Prix, 1

.and scope.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
la in is :
1. In a lamp, a body portion, a forward light opening, a rear reflector, and
-detachable protecting shields.
2. In a lamp, a body portion, a front light opening and lens, a rear reflector, and
removable protecting shields therefor.
3. In a lamp, a body portion, a rear reflector, a front reflector, a lens carried by
said front reflector, and detachable protecting shields carried by the body of the lamp,
said shields having central transparent portions.
4. In a lamp, a body portion, a rear reflector, a front reflector, said front reflector
being hinged to the body of the lamp and carrying a lens, detachable protecting shields
for both of said reflectors carried by the body of the lamp.
5. In a lamp, a front reflector hinged to the body thereof and carrying a lens, a
"rear reflector detachably carried within said lamp, and removable shields carried by
the body of the lamp adjacent to said reflectors.
6. In a lamp, a body portion, a detachable rear reflector, a front reflector, and
protecting shields therefor carried by the body of the lamp.
7. In a lamp, a body portion, a forward light opening, a rear reflector, and a
protecting shield carried by the body of the lamp.
