PROVISIONAL SPECIFICATION.
A Pneumatic Bearing Spring or Antivibration Arrangement for
Cycles and other Vehicles.
I, WILLIAM SHEPHARD SHREEVE of Shrewley, Warwick Estate Agent do
hereby declare the nature of this invention to be as follows:-
This bearing is intended to prevent the concussion induced in vehicles when
passing over rough roads.
It consists of one or more hollow cushions, cylinders, boxes, spheres, or rings,
made of india rubber, or other air tight pliable material, capable of being inflated
with air, either before, or after being made, and provided with an upper and lower
seating of metal or other strong material, with a telescopic arrangement attached
thereto, resting upon the pneumatic portion, formed of tubes or flanges, which
allows of one of the seatings to be fixed, or to be formed on the frame of the
vehicle, while the tube of the other seating is made to move easily up & down
within the tube of the first, with ball bearings or otherwise, by the momentum of
the pneumatic cushion, and at the same time is kept perfectly steady by the
telescopic arrangement, and has a stop or stops to prevent the tubes of the
telescopic arrangement being withdrawn too far, the one from the other. I place
the pneumatic bearing between the axis or support of the wheel and the body of
the cycle or carriage.

A Pneumatic Bearing Spring or Antivibration Arrangement for
Cycles and other Vehicles.
I, WILLIAM SHEPHARD SHREEVE of Shrewley, Warwick, Estate Agent 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 invention consists of the interposition of a pneumatic pad or spring between
the body of the cycle motor car or other vehicle and the wheels or support thereof,
so that the whole of the body of the vehicle & its load is supported upon the pad
or pads, thus preventing the transmission of vibration set up in the wheels, while
the wheels are held in position by the telescopic arrangement.
On the accompanying drawing. the telescopic arrangement is indicated as
between the letters A. B; the sockets or female part of the telescope is held firmly
at the points A. B. and the male rods or tubes are connected to the axis of the
wheels at one end and to the lower seating of the pneumatic pad at the other end,
and move easily up and down within the female parts or sockets; and the

page_text: pneumatic pad and its upper seating intervenes between the wheels or supports
thereof and the body of the cycle or other vehicle.
Figure 2, a' shows a compact form of telescopic arrangement formed on the axis
or axle of a tricycle or other vehicle having the lower seating of the pad or spring
on the axle, and the upper one on the body of the vehicle, which rests upon the
pad or spring and prevents the transmission to the body of any shock or, vibration
received by the wheels; a2 of the same figure indicates by dotted lines a similar
arrangement but in an extended form, the male portion of the telescope being
elongated. It is evident that the action of the spring is the same whether the
compact, or the extended form of construction be adopted.
Figure 1. shows the application of the spring to the back part of a cycle; in
the compact form the pad is fixed near the axle or axis of the wheel; it also
indicates by dotted lines the extended form with the transmitting rod or tube
running up to the lower seating of pad which is immediately beneath the body of
the cycle: the pad in both arrangements intervenes between the wheels or supports
thereof, and the body of the cycle or other vehicle.
Figure 3, a' shows the compact form; in this case the telescope is formed
within the head of the cycle, or the back, and the pal is fixed immediately beneath
the head or the back, and intervenes between the support of the wheels and the
body of the vehicle and a2 shows the extended form, which is fixed to, or formed
in the crutch or support of the wheel, and has the pad immediately beneath the
head of the machine and the body, the latter resting upon it.
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;
1. The pneumatic spring consisting of an upper and lower seating having a
pneumatic pad intervening, and the male and female telescopic arrangement in
connection therewith; (the telescopic arrangement being provided with, or without
ball bearings) placed in proximity to the axis of the wheels, or immediately
between the body of the cycle or other vehicle and the supports of the wheels, in
such manner that the body of the cycle rests entirely upon it, and is supported by
the pneumatic pad or pads, while the wheels are kept in position by the lower
portion of the telescopic arrangement.
2. The telescopic arrangement formed within the head itself, or the back for
cycles motor cars and the like, with the pneumatic pad and seating in connection
therewith as before described, the pad being immediately beneath the head, or the
back, and under the body of the cycle or other vehicle, and between the support of
the wheel or wheels and the body of the cycle or other vehicle.
