Improvements in Handles for Bicycles and the like.
I, CLEMENTINE JONES, 34 Stanhope Gardens Green Lanes Harringay. Middlesex,
Widow and administatrix of the estate of the late George Owen Jones of 148
Harringay Road, West Green Tottenham, 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 consists of a handle for bicycles, having an elastic outer covering
so arranged that it can be inflated with air for the purpose of preventing the vibration
of the machine from being communicated to the hands and arms.
In order to reduce the shock, jar, or vibration when riding which is communicated
to the hands and arms of the rider, I provide an air cushioning between the handle
bar and the inflatable covering, sleeve or grip.
In order that my invention may be fully understood, I will now refer to the
annexed drawings, in which, for purposes of illustration, I have shewn convenient
ways in which my invention may be carried out, but it is understood that there are
various ways of arranging for the inflation of the outer covering sleeve or grip, and
handle bar.
Figure 1. is a longitudinal section of a handle bar shewing inflated covering sleeve
or grip in position upon same.
Figure 2. longitudinal section of a modified arrangement
Figure 3. longitudinal section of a modification.
Figure 4. view of covering sleeve or grip detached from Figure 3.
Figure 5. longitudinal section of a further modified arrangement of sleeve.
Referring to Fig. 1, a is the inflatable covering, sleeve or grip which is provided
with the cauvas or covering of suitable material and is secured in position upon the

page_text: hollow handle bar b by means of the cap c and socket piece d. The sleeve inflatable
covering or grip is provided with the inwardly projecting feather-edged piece a¹.
The handle bar is rendered air tight so that when air is pumped into same through
the valve e which may be of any convenient and well-known form of construction, the
air will pass through the aperture f and will form a layer between the handle bar
and inflatable covering, sleeve, or grip thus forming an air cushioning and reducing
the jar or vibration communicated to the hands of a rider.
In Figure 2 the inflatable coverings, sleeves or grips, are carried as before on the
handle bar b and the tube b' is carried therein, and may be continued from both ends
of the handle bar communicated at through the handle bar so as to enable air to be
pumped between the handle bar and the inflatable covering sleeve or grip through
the medium of the valve g which may be of any suitable construction. If desired
the handles may be separately inflated.
In Figure 3 the inflatable covering, sleeve or grip, is carried upon the handle bar
as before and is provided with a valve of any suitable construction at or about the
place, shewn for the purpose of enabling inflation to take place. The feather
edge performs a very important function inasmuch as the inflation causes the same to
engage upon the handle bar rendering the joint airtight, but it will be readily seen
that there are other ways in which the inflatable covering sleeve or grip can be
secured to the handle bar.
In Fig. 5 the inflatable covering sleeve or grip is shaped as shewn and may be
independently inflated; or by being provided with perforations in its inner surface
at or about the points which communicate with apertures in the handle bar; it may
then be inflated from the handle bar as before.
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 :-
1. The employment of a hollow handle bar with an inflatable covering sleeve or
grip; said hollow handle bar being arranged to contain air at suitable pressure &
communicating with an inflatable covering, sleeve or grip for the purpose of
providing a cushioning of air between the handle bar and said inflatable covering
sleeve, or grip.
2. An inflatable sleeve or grip having at its ends inwardly projecting feather edges
for ensuring a tight joint when in position upon the handle bar, in conjunction with
suitable caps or sockets.
3. The improved pneumatic handle constructed in accordance with this specification
and illustrated in the drawings hereunto annexed.
Dated this 23rd day of August 1897.
