COMPLETE SPECIFICATION.
Improvements in connection with Cycles and other Vehicles.
1, DAVID JAMES, Tonyrefail Station, near Porth, Glam. Station Master, 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:-
The object of this invention is to render unnecessary the use of pneumatic and
other like tyres, and this result I obtain by interposing between the axle bearing
and the frame of the machine a pneumatic tube or air-chamber contained in a
casing. Within the casing and resting on the lower part thereof is a trough or
half tube or channel in which rests the lower part of the air-chamber. An
opening is formed in the lower part of the casing through which passes a slide or
plunger, attached to the lower part of the trough and to the under part of the
casing are attached guides between which the plunger slides, stops or other
contrivances being provided to limit the movement of the slide or plunger. To
the lower end of the slide or plunger is attached the bearing for one end of the
axle and to the upper part of the casing is attached a part of the frame of the
vehicle, such as the arm of the fork, in the case of a cycle. A spring like effect is
thus obtained by the action of the plunger slide being forced up under the air-
chamber within the casing. In the case of a cycle, there would be one of these
arrangements at the lower end of each arm of each fork.
In order that the nature of my invention may be the more readily understood,
I make reference to the accompanying sheet of drawings in which, Fig. 1 is a part
sectional view, and Fig. 2 an end view with section on line A. B. Fig. 1. Similar
letters refer to the same parts wherever occurring. a outer casing of any metal
or suitable material, and of any (but preferably circular) cross section. This
casing is in three pieces, one upper and two lower connected by flanges and screws,
bolts, or equivalents. b is part of the frame of the machine and attached to a.
c space between the two lower pieces of a. d trough like support for air-chamber é.
The air-chamber may be of rubber or other inflatable material. f slide or plunger
attached to d. g guides for f and attached to lower part of a. h stops attached to g.
i stops attached to f. j bearing of wheel axle and attached to f. k axle. I hub
of wheel. Although I have shown and explained the invention as applied to a
cycle, nevertheless I do not restrict myself to that one use, as it may be employed
for any other machine, for any other purposes, and in any other position. Further
I do not confine myself to the precise configuration, relative proportions or
disposition of the various parts, as any or all of them may be varied for use in any
required position, and under any given circumstances, without departing from the
essential features of the invention.
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..

page_text: the casing, to the said trough being attached a plunger or slide, working in guides
attached to the lower part of the casing, the said plunger or slide carrying the
bearing for the wheel axle, stops being provided on the guides and slides for
limiting the movement of the latter, the whole substantially as described in the
above specification and exemplified in the accompanying drawings.
2. The improvements in connection with cycles and other vehicles substantially
as described in the above specification and exemplified in the accompanying
drawings.
Dated this 16th day of November 1896.
