page_text: I, ARCHIBALD BARR, Professor of Engineering in the University of Glasgow, do
hereby declare the nature of this Invention to be as follows:-
The object of my Invention is to provide convenient and ready means for the
carriage and exhibition of maps or guides on cycles, motor cars, or other vehicles.
I provide a case, attachable to the handle bar or other part of the cycle or other
vehicle in front of the rider or driver, in which case the map is placed. The upper
surface or cover of the case may be composed of celluloid or other transparent but
non-breakable substance, the remainder of the case being composed of metal or
other suitable material. The case may be so constructed that rain or dust falling
upon the cover will not readily gain access to the interior, and for that purpose the
transparent substance of which the upper part or cover is constructed may itself be
turned downwards at the edges, or it may be fixed to a frame so constructed as to
exclude rain and dust.
The transparent cover may be supported from the bottom of the case or
part connected thereto, by spring attachment or the bottom itself, or the cover,
may be made springy in form and material, so that single maps or folded maps of
different thickness may be held steadily in the case, and the arrangement may
be such that the portion of the map exhibited may be pressed flatly against the
transparent cover.
A spring clip or other attachment of special construction may be provided to
attach the case to the handle bar, or other portion of the cycle or other vehicle
in a suitable position for the convenient exhibition of the map to the rider or
driver.
The case may be so connected to the clip or other supporting piece, that it may
be turned relatively to the vehicle, so as to present the representation of the road
being traversed in the direction in which the cycle or other vehicle is proceeding.

I, ARCHIBALD BARR, Professor of Engineering in the University of Glasgow, 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
5 statement:-
The object of my Invention is to provide convenient and ready means for the
carriage and exhibition of maps or guides on cycles, motor cars, or other vehicles.

page_text: I provide a case attachable to the handle har or other part of the cycle or other
vehicle in front of the rider or driver, in which case the map is placed. The upper
surface or cover of the case may be composed of celluloid or other transparent but
non-breakable substance, the remainder of the case being composed of metal or
other suitable material. The case may be so constructed that rain or dust falling
upon the cover will not readily gain access to the interior, and for that purpose the
transparent substance of which the upper part or cover is constructed may itself be
turned downwards at the edges, or it may be fixed to a frame so constructed as to
exclude rain or dust.
The transparent cover may be supported from the bottom of the case or
parts connected thereto, by spring attachment or the bottom itself, or the cover,
may be made springy in form and material, so that single maps or folded maps of
different thicknesses may be held steadily in the case, and the arrangement may
be such that the portion of the map exhibited may be pressed flatly against the
transparent cover.
A spring clip or other attachment of special construction may be provided to
attach the case to the handle bar or other portion of the cycle or other vehicle
in a suitable position for the convenient exhibition of the map to the rider or
driver.
The case may be so connected to the clip or other supporting piece that it may
be turned relatively to the vehicle, so as to present the representation of the roail
being traversed in the direction in which the cycle or other vehicle is proceeding.
In order that my Invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of Drawings in the several Figures of
which corresponding parts are marked with the same letters of reference.
Figure 1 illustrates in front elevation a very convenient form of map carrier
made in accordance with and constituting my Invention.
Figure 2 is a transverse section taken on the lines zy, Figure 1.
Figure 3 is a part back view.
Figure 4 is a side elevation drawn to a reduced scale of the map carrier applied
to a cycle of which only a portion is shown necessary to enable the application of
my Invention to cycles to be understood.
The frame of the case which is constructed of metal or other suitable material
is marked A and is provided with a groove or hollow head a, formed along its four
inner edges, for the reception of a square or other shaped transparent cover B
preferably of non-breakable substance such as celluloid forming the outer surface
of the map carrier. The said frame A is connected to the metal or other plate C
forming the back of the case by the broad hinge D and two springy pieces of
metal E, F, seen more particularly in Figures 2 and 3. By virtue of the two
springy pieces E, F, which are riveted to the back of the metal plate C, the map
carrier may conveniently receive a map of single thickness or one folded into
several thicknesses, and the exhibited surface will he pressed flatly against the
transparent cover B, as hereinbefore described.
To the back of the plate C connected by the screws is the clip M of the
construction shown in Figures 2 and 3. The jaws H of this clip clasp the handle
bar of the eyele while the jaws I clasp the fork pillar as seen in Figure 4.
In the construction shown the clip is formed by the bending of a single piece
of sheet metal cut to a somewhat cross shaped form, the jaws I being formed out
of the head of the cross, the jaws H out of the transverse arms and the stay G
from the long stem of the cross. The form of the clip may be modified to suit the
part of the vehicle to which it is to be attached.
By means of a recessed ring J which is screwed to the plate C the disc K to
which the said clip M is attached is capable of an axial motion which allows the
map carrier to be turned at will by the cyclist or rider.
When it is desired to replace the map with another one or to turn or unfold the
one presently contained within the carrier, the frame A with the transparent
cover B is opened by loosing the clip L and lifting the cover in the directions

page_text: indicated by the arrows in Figure 2 and closed again at will and clamped with the
spring clip or lock arrangement marked L.
In some cases instead of the clip and disc above described, I attach to the
bottom of the case a rod X which passes through a hole in the top of the handle
bar, so as to support the case and at the same time allows it to be so rotated as to
present the representation of the road being traversed in the direction in which
the cycle is proceeding.
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
claim is:-
The map or guide carrier for cycles or other vehicles, constructed substantially
as and for the purposes herein before described and illustrated in the accompanying
sheet of Drawings, consisting essentially of the combination of a clip or other
device for connection to the handle bar or other suitable part of the cycle or other
vehicle, a frame for holding the map or guide and capable of being rotated
relatively to the cycle and a cover of transparent but non-breakable material such
as celluloid.
