PROVISIONAL SPECIFICATION.
An Improved Anti-vibrating Handle for Velocipedes and other
purposes.
HARRY LUCAS The "Tom Bowling" Lamp Works Little King Street,
Birmingham Lamp Manufacturer do hereby declare the nature of this invention
to be as follows:-
My invention relates to handles for velocipedes & other purposes and my object
is to make a handle which is soft and flexible and consequently does not conduct
vibration and at the same time is so shaped that one's hand can obtain a very firm
hold on it. I use india rubber or other suitable soft or flexible material and make
the handle corrugated both inside and out, or it may be corrugated outside and
arched inside. The corrugations may run lengthwise from or near end to end of
the handle or they may run round it.

COMPLETE SPECIFICATION.
An Improved Anti-vibrating Handle for Velocipedes and other
purposes.
HARRY LUCAS, The Tom Bowling Lamp Works, Little King Street,
Birmingham, Lamp Manufacturer, 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 :-
My invention relates to handles for velocipedes and other purposes and my object
is to make a handle which is soft and flexible and consequently does not conduct
vibration so much as ordinary handles do and at the same time is so shaped that
one's hand can obtain a very firm hold on it.
I prefer to use india-rubber as the most suitable material and to make the
handle corrugated both inside and out as shown in longitudinal section in Fig. 1.
The straight dotted lines represent the handle bar on to which the handle is fitted,
and it will be seen that there is a plain part at each end of the handle to form a
seat or bearing on the handle bar. The supports of the arches or corrugations
touch the handle bar lightly and readily yield when the handle is grasped thus
making it soft and springy. I prefer to make the handle with one end closed, and
a metal ring or ferrule round the open end serves to bind the handle on the bar, the
opening of the handle being made rather smaller than the bar so that when the
handle is forced on, it is squeezed between the bar and the ferrule sufficiently to
hold it on the bar.
The handle may be made with the outside plain as shown in Fig. 2 but I do not
consider this so good as the form shown in Fig. 1.
Any number of arches or corrugations may be used and instead of a series as
shown in Figs. 1 and 2, the handle may be made with a single arch and a support
or bearing at each end as shown in Fig. 3. In this case the walls of the handle
will require to be thicker than in the handles shown in the first two figures, or the
india rubber will require to be of a harder quality to make out for the absence of
a series of supports, and the exterior may be made corrugated as shown or it may
be smooth. If preferred, the corrugations may run lengthways from or near
end to end of the handle and cross sections of such handles are shown in
Figs. 4 and 5.

page_text: 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 construction of an india rubber handle with internal and external
corrugations substantially as described and illustrated in Fig. 1.
2. The construction of an india rubber handle with internal corrugations and a
smooth exterior substantially as described, and illustrated in Fig. 2.
3. The construction of an india rubber handle having a bearing at each end for
fitting on a bar and either with or without a corrugated exterior substantially as
illustrated in Fig. 3.
4. An india rubber handle having internal and external corrugations running
lengthways with the handle as shown in cross section in Fig. 4.
5. An india rubber handle having internal corrugations running lengthways with
the handle and a smooth exterior as shown in cross section in Fig. 5.
6. An india rubber handle having end bearings for supporting the handle on a
bar and either with or without bearings between the two end ones.
7. An india rubber handle having end bearings for supporting the handle on a
bar, with or without bearings between the two end ones and with an end metal ring
or rings for pinching the handle on the bar.
Dated this 2nd day of April 1892.
