IMPROVEMENTS IN REFLECTORS AND FITTINGS THERETO
Year: 1885

page_text: I, THOMAS HENRY COLLINS, of 7 The Square, in the City of Winchester, in the
County of Hampshire, hairdresser, do hereby declare the nature of my invention
for "IMPROVEMENTS IN REFLECTORS AND FITTINGS THERETO," to be as follows:-
My invention relates to a device for the collection upon. reflectors and sub-
sequent diffusion of rays of light from a gas jet or other source of illuminatiou,
which are at present thrown vertically down upon the lamp frame, and thus
wasted, and also to certain fittings thereto which permit of the easy cleaning or
replacing of the reflectors and of the adjustment of their angles.
My invention is more particularly applicable to street lamps, and is as follows:-
Embracing the upright portion of the gas pipe, some distance below the nipple,
is a sleeve, which may be fixed at any height by means of a thumb screw. This
sleeve has a pair of lateral and upwardly curved arms, across the end of each of
which is a cross plate provided with a vertical slot. Higher up the gas pipe and
almost immediately below the nipple, is fixed a pair of arms projecting in the sa ne
vertical plane as the two arms aforesaid, but for a much shorter distance, and
formed as a horizontal plate with vertical slots. The two pairs of projecting
arins just specified, form the supports for a pair of frames carrying the reflecting
plates, the difference in degree of projection and in relative height upon the gas
pipe determining the angle at which the reflector shall rest. Each reflector frame is.
fitted at the back with projecting pieces, which pass through the vertical slots in
the supporting arms aforesaid, and retain the frame in position. The upper
projecting piece is however screw threaded at its end, so as to permit of a weight
being screwed thereupon, to prevent accidental withdrawal of the projection on
the frame from the slot and to give the frame sufficient weight to prevent disturbance.
The lower projection in place of being straight is curved in form, so as to virtually
form a binge when engaged with the vertical slot in cross piece at the head of the
lower supporting arm, and thus when the weight is screwed on and the upper
projecting piece cannot be withdrawn from the slot, the reflecting frame is locked
in place and cannot be withdrawn until the weight be unscrewed from the upper
projecting piece.
.

page_text: The reflector frame consists of a thin preferably slightly dished plate, of a
rectangular form, but deprived of the upper corners. Its edges are slightly bent
over except at the base, and the upright portion of one side. Plates of reflecting
material can be slipped under the bent edges, and the lower-most plate can be slid
along from the portion of the edge which is not bent over, thus locking the others
in place, a clip or a slide being provided, to lock this last named. The slightly
dished form of the reflecting plate, ensures a proper diffusion of the rays of light.
It is to be oberved that my reflectors being placed below the light, possess, in
addition to the advantages already specified, that of non-liability to the collection
of soot from the flame.

I, THOMAS HENRY COLLINS, of N° 7 The Square, in the City of Winchester,
in the County of Hampshire, Hairdresser, 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 a device for the collection upon reflectors, and subsequent
diffusion, of rays of light from a gas jet, or other source of illumination, which are
at present thrown vertically down upon the lamp frame, and thus wasted, and also
to certain fittings thereto, which permit of the easy cleaning or replacing of the
reflectors, and of the adjustment of their angles.
In order that my invention may be better understood, I now proceed to describe
the same in relation to the drawings hereunto. annexed reference being had to the
letters and figures marked thereon.
Like letters refer to like parts in the different figures.
Figure 1 is a perspective view of my device in position.
Figures 2, 3, 4, 5, 6 and 7 are views of various details.
My invention is more particularly applicable to street lamps, and is as follows:-
Embracing the upright portion of the gas pipe, some distance below the nipple,
is a sleeve A, which may be fixed at any convenient height by means of a thumb
screw, a.
This sleeve has a pair of lateral and upwardly curved arms B, across the end of
each of which is a cross plate C, provided with a vertical slot D.
Higher up the gas pipe, and almost immediately below the nipple, is fixed a
pair of arms E (see detail figures 2 and 3) projecting in the same vertical plane as
the two arms B aforesaid, but for a very much shorter distance, and formed as a
horizontal plate with vertical slots D¹. The two pairs of projecting arms B and E,
just specified, form the supports for a pair of frames F, carrying the reflecting
plates G, the difference in the degree of projection and in relative height upon the
gas pipe determining the angle at which the reflector frame shall rest. Each
reflector frame is fitted at the back with projecting pieces H H', which pass through
the vertical slots in the supporting arms aforesaid, and retain the frame in position.
The upper projecting piece H is however screw threaded at its end, as shown at h
in figure 2, so as to permit of a weight being screwed thereupon to prevent
accidental withdrawal of the projection on the frame from the slot, and to give the
frame sufficient weight to prevent disturbance. The weight however may be solid
with the projections as shown at h¹, figure 2, in which case a side way d¹, figure 3,
is cut to permit of its entry into the slot. The lower projections H¹, in place of
being straight, are curved or bent in form, so as to virtually form hinges, when
engaged with the vertical slots in the cross piece at the head of the lower supporting
arın B.
Thus, when the weight is screwed on, and the upper projecting piece cannot be
withdrawn from the slot, the reflecting frames are locked in place, and cannot be
withdrawn until the weight be unscrewed from the upper projecting piece.

page_text: The reflector frame F consists of a thin, preferably slightly dished plate, of a
rectangular form, but deprived of the upper corners. The method of locking the
plates can be better seen by reference to figures 4, 5, 6 and 7. The edges of the
frame are slightly bent over except at the base and the upright portion of one side
at K. Plates G of reflecting material can be slipped under the bent edges, and the
lowermost plate can be slid along from the portion of the edge K which is not
bent, thus locking the others in place, a clip or a slide L being provided to lock
this last named.
The slightly dished form of the reflecting plate ensures a proper diffusion of the
rays of light. It is to be observed that my reflectors, being placed below the light,
possess, in addition to the advantages already specified, that of non liability to the
collection of soot from the flame.
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
The combination with the stem of a gas jet of specially constructed reflecting
device and adjustable supports, substantially as and for the purposes specified.
