Improvements in Lanterns.
I, EDWIN M ROSENBLUTH, of 807, North Twenty-fourth Street, in the City and
County of Philadelphia and State of Pennsylvania, United States of America,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly descubed and ascertained in and
by the following statement
-
My invention relates to vehicle and other lamps or lanterns, and especially to
the reflecting devices or plates ordinarily mounted in and carried by them.
As 18 well known, in the continued use of lanterns, the reflectors receive deposits
of soot and other matters which impair their capacity for reflection, and it 18
therefore desirable to so mount them that they may be readily removed for the
purpose of being cleaned and polished.
It is, moreover, a desideratum that reflectors thus removably mounted within
lanterns, should be supported in position in such manner as not only to he main-
tained against displacement but also as to preclude the rattling of the parts in
the oscillation to which the lantern in the travel of the vehicle is subjected
My invention aims to provide, in connection with vehicle lanterns and their
reflector, reflector-holding or supporting devices of such character as to support
the reflectors in position in the lanterns with such firmness as to preclude their
displacement or rattling, and, as, together with the reflector, to be easily and
readily removable
In the accompanying drawings I show and herein I describe, a good form of
a convenient embodiment of my invention, the particular subject-matter claimed
as novel being hereinafter definitely specified.
It is to be understood that my improvements herein set forth are applicable in
connection with vehicle and other lanterns of any character, and particularly also
those in which the combustion chamber is vertically disposed.
In the accompanying drawings,
Figure 11s a central, sectional, elevational, view of a lantern equipped with a
preferred form of my improvements
Figure 2 18 a view in perspective of the reflector shown in Figure 1 removed
from the lantern
Figure 3 is a view in face elevation of the reflector shown in Figures 1 and 2
Figure 4 19 a front elevational view of the lamp and contained reflector shown
in Figure 1, the casing of the combustion chamber being shown in section in the
plane of the dotted line 4-4 of said Figure 1
Similar letters of reference indicate corresponding parts
Generally stated, my invention comprehends the provision of a spring holder of
substantially the character herein described and claimed, adapted to removably
secure a reflector in place within a lantern
In the drawings,
A 19 the combustion chamber of the vehicle lantern,-which in the form shown
in Figures 1 and 4 hannens to be bouzontally-dienosed

page_text: B 18 the lamp chamber of said lamp, which serves to contain the lamp b, the
wick tube of which projects within the combustion chamber, and C is the cap or
chimney of the lantern, disposed above the combustion chamber which opens into
it through the chimney throat c
D 18 a supporting device by means of which the lantern may be connected to
the vehicle.
E 18 a swinging door, mounted in hinged relationship with respect to the flang
mouth of the combustion chamber, and provided with the ordinary lens e,
while
F 18 a jewel-provided light opening in the rear end wall of the combustion chamber
G is the reflector, which may, as stated, be of any desued character
This reflector 18 shown as provided with a central aperture 7 in line with the
rear light opening F, to render the light visible from the rear of the lantern,-
and said reflector is also shown as provided with a glass protecting plate q³, dis
posed in front of its silvered or reflecting face and seated behind forward and in-
wardly inclined circumferential lips g' mounted upon or formed as integial
continuations of the body of the reflector.
The glass protecting plate may be conveniently secured beneath said lips g by
means of a spring annulus G* disposed in front of said protecting plate and
self-retaining in position by its expansion against the inner face of said lips
The engagement of the annulus within the lips will serve to normally retain
the protecting plate securely in position, while the removal of the annulus and
plate to permit of the cleaning of the face of the reflector may be conveniently
effected by compressing or forcing together the outwardly turned ends g of the
annulus.
The holder, which may be made in a great variety of forms to suit the vary-
ing requirements of the different forms of combustion chambers of the numerous
styles of lamps manufactured, is preferably formed as a multi-armed single-piece
wire structure of the general foimi indicated in the drawings, that is to say, em-
bodying four aims h³ ³ h h all extending forwardly from the effectoi, and
all slightly divergent or having an outward spring or set, to adapt them to retai
their hold against the wall of the combustion chamber within which they are
entered and slightly compressed
I prefer to so arrange the holder that, when the reflector has been seated in its
proper position, the arms, or one or more of them, will be seated or engaged
within any suitable recess aperture on depression of the combustion chamber m
order to positively lock the reflector in position, and to that end the arms are
shown as prolonged and merged into each other at then front extremities, and as
so fashioned as to constitute a locking projection 5, which is 80 located and
arranged with reference to the other parts of the lantern that when the reflector
is mounted in the combustion chamber and locking projection will extend up
within the throat of the chimney and by contact with the forward edge of sand
throat prevent any undue forward movement of the reflector
The bodies of the arms h¹ h h h preferably extend somewhat to the rear of
the reflector, and are bent to form return bends ho, which project rearwardly from
said reflector, and, by contact with the rear wall of the combustion ebamber,
serves to maintain the reflector in proper position with relation to said rear wall
and preferably in such position that an air chamber or space is formed behind said
reflector, and which also serve to impart to the arms the desired spring set
The holder may be conveniently secured to the reflector by the engagement of
the lengths which respectively connect the return bend of the arm h¹ with
the return bend of the arm h³, and the return bend of the arm ³ with the return
bend of the arm within lips or clips he conveniently constituted by outwardly
and rear waidly curved tongues mounted on or formed as integral continuations
of the marginal portion of the reflector
It will also be understood that the arrangement of holder described, in which
four arms, all formed from one continuous strand of metal and each provided with
a projection 6, and the whole secured to the reflector by the clips A, are em-

page_text: ployed, is a preferred arrangement merely, and that these details of construction
and arrangement may be omitted or varied at will, without departure from the
spirit of my invention
To remove the reflector from the combustion chamber, it is only necessary to
open the door of the chamber, to grasp and deflect the arms ha h³ to carry the
locking projection out of engagement with the chimney throat, and, retaining said
locking projection deflected, to draw the holder and reflector out through the open
door.
In returning the reflector to position, it is to be merely forced real wardly
through the combustion chamber, until the bends he encounter the rear wall of
the chamber, and the locking projection engages with the chimney throat
Having now particularly descubed and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim 18
1. In combination, a lamp, embodying a combustion chamber having an open-
ing formed in its wall, a reflector, and a holder for said reflector which consists
of wire spring arms at theu inner ends connected with the reflector, and a locking
projection formed as part of said reflector holder and adapted to engage in said
opening in the wall of the combustion chamber, substantially as set forth
2. In combination, a lamp, embodying a combustion chamber having an open-
ing formed in its wall, a reflector, and a holder for said reflector which consists of
wine spring arms at the inner ends connected with the reflector, and a locking
projection formed as part of said reflector holder and as a continuation of two
of said arms and adapted to engage in said opening in the wall of the combustion
chamber, substantially as set forth
3 In combination, a lamp, a reflector, and a holder for said reflector which con-
sists of a series of spring aims at the inner ends connected with the reflector,
and as to their bodies extending away from it, and at its rear formed with retuin
bends which are adapted to make contact with the rear wall of the combustion
chamber, substantially as set forth
4 In combination, a lantern or lamp, a reflector, and a holder for said reflector
which consists of a series of wire aims disposed in substantial parallelism with
the axis of the reflector, extending to the front and rear of said reflector, at the
rear piovided with return bends which are connected to the marginal portion of
the reflector, and at the front diverging from each other, substantially as set
forth.
5 In combination, a lantern or lamp, a reflector, and a holder for said reflecto
