PROVISIONAL SPECIFICATION.
An Appliance for Reducing the Atmospheric Pressure, or Wind
Resistance on Cycles, Cyclists, Motor-cars, Motor-cycles, and
the like.
MARWOOD JOHN OLIVER Merchant St. Tudy, R.S.O. Cornwall, I do hereby
declare the nature of this invention to be as follows:-
I place in front of the Cycle Cyclist or Motor-car, a wind or air divider con-
sisting of Metal, Cardboard, Buckram or any other like material equivalent of a
V shape, the acute angle projecting forward, thereby dividing the air regularly
instead of meeting the resistance at right angles.
This arrangement can be attached to the Cycle, Cyclist or Motor-car by spring-
clips, buckles, buttons or otherwise. I claim by my invention a great decrease of
air or atmospheric pressure as the angle-shape shield cleaves the air and thus
reduces the atmospheric pressure.
Dated this 14th day of October 1896.

COMPLETE SPECIFICATION.
An Appliance for Reducing the Atmospheric Pressure, or Wind
Resistance on Cycles, Cyclists, Motor-cars, Motor-cycles, and
the like.
MARWOOD JOHN OLIVER Merchant St. Tudy, R.S.O. Cornwall, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to shields for persons, bicycles and similar vehicles, and
the object thereof is to provide an improved device of this class, which is intended
to prevent the pressure of the air on the person, cycle or other vehicle and on the
body of the rider when said vehicle is in motion, a further object being to pro-
vide shields which are adapted to be connected to the person and with the frame
of the cycle or similar vehicle in such a manner as to divide the air and prevent
the same from striking the vehicle and the body of the rider when said vehicle is
in motion and so as to avoid the retarding pressure of the air which is a great
objection to vehicles of this class when in motion.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part in which Fig. 1 is a side view of a bicycle
fitted or provided with my improvement.

page_text: Fig. 2. Front view of the upper or detachable part to be worn on the person.
In the drawing forming part of this specification the separate parts of my
improvement are designated by the same letters of reference in each of the views,
and in the practice of my invention, I provide shield A. B, for the purpose herein
specified, said shield being composed of any desired material, and the shield is
connected at the opposite sides thereof with the support of the axle of the guide
wheel F as shown at D, this connection being made in any desired manner. The
shield A. B is substantially V shaped in cross sections, and extends downwardly
in front of the guide wheel F, and terminates within a short distance from the
ground, and the upper end thereof projects upwardly to a predetermined distance
above the wheel.
The sides of the shield A. B, extend upwardly parallel with the forward fork
of the vehicle in which the guide wheel F, Fig. 1, is mounted, the sides thereof
are then curved outwardly and upwardly and the upper portion of the shield is
connected on either or each side at the top of fork as shewn at E, Figs. 1 and 5,
and upright bar as shewn at G, Figs. 1 and 3. H is the acute angle of
shield I. I, J.J, and KK, holes in which straps or such like are placed for attach-
ment to the person. The upper part being attached to the machine by spring
clips bolts and nuts or otherwise as shewn at C. G and E, can be detached, and
attached to the person by straps and buckles, buttons or otherwise in the form of
a waistcoat as Fig. 2.
The upper part of the shield I attach to the pillar of machine by a swivel ring
as shewn at G, Figs. 1 and 3, to which two arms or stays are attached as at M,
Fig. 3, rising to any desired height' on the inside of the shield, said stays or arms
being bolted to shield as at N or fastened by a clip to handle bar as at C,
Figs. 1 and 4, to turn with the handle bar. The under part of top of shield, and upper
part of bottom of shield are held to sides of front fork by clips as shewn at E,
Figs. 1 and 5 with set screws to tighten as at R Fig. 5. My invention is not
limited to the material of which the shields are composed nor to the means
herein described for connecting the same with the frame of the vehicle or body
of the person, and any suitable construction may be employed for purpose.
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:
1st. The combination with a bicycle or similar vehicle of shields being com-
posed of side-plates which project backwardly and which are secured to the frame
of the vehicle or person, said side-plates being projected forwardly and brought
together so as to divide the air and prevent the same from striking the vehicle
and the body of the rider substantially as described.
2dly. Shields on cycles and similar vehicles, said shields being adapted to be
connected with the forward part of the frame substantially as described.
Dated this 12th day of July 1897.
