Improvements in or relating to Lamps for Velocipedes and other
Vehicles.
GUSTAVE WILHELM MÖHRSTÄDT 44 Bradford Street Birmingham Manu-
facturer do hereby declare the nature of this invention to be as follows:-
This invention relates to cycle or velociped and carriage lamps and refers to
parallel connecting bars and joints for connecting a lamp with the braket by which
it is carried, to an arrangement or device by which a lamp may be set at a desired
angle to throw the light either at a short or long distance, to an arrangement for
holding the oil resevoir by means of a concealed spring which is applicable also
for the doors.
According to the first part of my invention I prepare or work. in the ends of
the connecting bars a flange in the shape of a eyelet I also prepare two plates with
ears, these ears are pierced and bend at an angle to receive the flange or eyelet
portion of the connecting bars or links, when so inserted in the pierced ears
of the plates the eyelet part is turned slightly outwards to prevent the bars or
links from releasing themselves when in use, this arrangement may be made
vice versa, that is the eyelets or turned up flanges may be worked in the plates and
the bars or links may be pierced, or if preferable I can fix or fasten an eyelet,. in
either of the plates or bars, my object is to dispense with the screws or pins
hitherto employed.
Referring to the second part of my invention I prepare a joint or hinge on a
suitable part of the lamp to obtain the oscillation so as to give the desired direction
to the light the oscillation or degree of angle being regulated either by a screw
lever or other suitable arrangment the third part refers to the oil reservoir which
is held in position by a concealed spring, the spring and catch being placed inside
the lamp and operated upon by a button or knob a similar arrangement may be
applied to the doors of lamps when suitable.

GUSTAVE WILHELM MÖHRSTÄDT Mechanical Engineer and Manufacturer
44 Bradford Street Birmingham 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 :-
This invention relates to cycle or velocipede and carriage lamps and refers to,--
Firstly. To parallel connecting bars and joints for attaching a lamp to the
bracket by which it is carried.

page_text: Secondly. To an arrangement or device by which a lamp may be set at a desired
angle to throw the light either at a short or a long distance.
Thirdly. To an arrangement for holding or keeping in position the oil or other
recervoir of a lamp by means of a concealed spring and catch.
I will now describe my invention by the aid of the accompanying drawings, in
which similar letters of reference relate to similar parts.
Referring to the drawings:-
Fig. 1 is a perspective view of a cycle lamp showing the form of connecting bars
and joints which I prefer to use.
Figs. 2 & 3 are end elevations of the plates, one to be attached to the back of
the lamp and the other to the bracket.
Figs. 4 & 5 are views of the connecting bars.
Fig. 6 shows my arrangement for altering the direction of the light by varying
the angle of the lamp.
Fig. 7 is a section through the upper part of same.
Fig. 8 is a view of an open lamp showing my arrangement for holding and
securing the recevoir.
According to the first part of my invention I prepare or work upon the ends
of the connecting bars (a) Figs. 1. 4. & 5 a flange (6), in the shape of an
eyelet. I also prepare the two plates (c) & (d). Figs. 1. 2 & 3 with ears (f).
which ears are pierced at (e). and bent at an angle to receive the flange or
eyelet portion (6). of the connecting bars or links (a) which are inserted in the
pierced ears (f). of the plates (c) & (d). After inserting the eyelets (b). in the
pierced portion (e) of the ears (f). the eyelets (b) are turned slightly outwards to
prevent the connecting bars or links (a) from releasing themselves when in use.
This arrangement may be made vice versa that is the eyelets or turned up flanges (b)
may be worked in the plates (c) & (d), and the links or connecting bars (a) may
be pierced to receive them, or if preferable I can fix or fasten an eyelet in either of
the plates (c) & (d) or in the bars (a). My object being to dispense with the
screws or pins hitherto employed.
Referring to the second part of my invention namely to alter the direction of
the light in cycle or carriage lamps (Fig. 6). I prepare a frame in the form of a
paralellogram Fig. 6. jointed or hinged at its corners (g). one side of said frame
represents the back plate (c). to which the lamp is fixed or fastened while the
opposite represents the bracket plate (d). by which the frame is fastened to a
cycle or other lamp bracket, a third side of the frame I make in two parts one part
to form a sheath (j) the other part (1) is so formed that it will slide into the
sheath () to enable me to shorten or lengthen this side of the frame or
paralellogram, the lamp oscillating on the hinges or joints (9) will alter the degree
of the angle as shown by the dotted lines in Fig. 6. and held in position by a
screw (). in the slide or inside plate (i) actuating on the sheath or outside plate (j)
after passing through the slot j1. or I may use any other suitable arrangement for
regulating the degree of angle.
As regards the third portion of my invention which is shown in Fig. 8 & refers to
the oil recervoir (k). being held in position by a concealed spring (s). I place
the spring (s). inside the lamp (m) and a catch (l). on the oil reservoir (a). and
operate them by means of a button or knob (n) the lamp being hinged as shown
at (t) (t) to facilitate the opening of the lamp. A similar arrangement to this may
be also applied to the doors of lamps when required.
my
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed, 1 declare that what I
claim is :-
1st. In lamps such as herein described the combination with the body of the
lanıp and the connecting bars provided with eyelets fitting into pierced holes
worked on the flanges of the lamp and bracket plates to formn eyelet joints
substantially as herein specified and illustrated in Figures 1. 2. 3. 4 & 5.

page_text: 2nd. Altering the direction of the light as thrown from a cycle and other lamp
by varying the angle of the lamp substantially as herein described and illustrated
in Figs. 6 & 7.
3rd. The holding of the reservoir of cycle and other lamps in a closed position
by means of a spring, knob & catch substantially as herein set forth & illustrated
in Fig. 8.
Dated this 22nd day of June 1895.
