COMPLETE SPECIFICATION.
Improvements in Hand Grips for the Handles of Tools, Cycle Handle
Bars, and the like.
I, KARLE HENRY GRANGER, of South Weymouth, in the County of Norfolk, and
State of Massachusetts, United States of America, Physician, 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 the invention is to provide a flexible or yielding hand grip for
tools and bicycle handle bars of such construction that the vibratory movement
of the handle or object grasped will not be communicated to the operator or to the
rider of the bicycle, and whereby the operator or rider will have a cushioned grip
surface, which surface will consist of a series of inflatable members, usually
placed in spiral arrangement.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar characters of reference indicate corresponding parts
in all the figures.
Figure I is a side elevation of the handle portion of the handle bar for a bicycle
to which the improvement is applied.
Figure II is a vertical section through the attachment, the handle section of
the handle bar being shown in side elevation.
Figure III is a vertical section taken substantially on the line 3-3 of Figure II.
I carrying out the invention, I have illustrated the application of the improve-
ment to the handle section A of the handle bar of a bicycle, but it will be under-
stood too that the application of the invention may be made with equally good
results to the handle of any tool, which handle is susceptible to a vibratory
movement when said tool is in use.
The handle section A is preferably reduced in diameter, as shown at 10 in the
drawings, from a point near its outer end to a point at or near its inner extremity,
and the said reduced portion of the handle is wrapped around by a tubing 11,
which, at its outer end is attached by a pin 12, bolt, clip, or its equivalent, to the
handle and the inner end of the said tubing which is in spiral arrangement around
the handle is carried through a sleeve or a clamp 14 of any approved description
and which is secured to the body of the tool handle and the termination of its
grip portion or to the handle bar of a bicycle and the termination of the grip
portion of the same. The inner end of tube 11 is provided with a valve 13, which
is secured to the tube in any suitable or approved manner, and extends inwardly
beyond the clip 14.
The tube 11 is adapted to be inflated with air, water, or any material capable of
imparting to the coils of the tube an elastic character and the said air, water, or
its equivalent, is introduced into the coil through the valve 13. It is therefore
evident that the gripping surface of a bicycle handle bar, or the handle of a tool
of any description may be formed in an economic manner and so that any vibra-

the person holding the tool or handle bar, to any appreciable extent.
I desire it to be understood that I do not confine myself to any particular
material for the construction of the coil or the shape of the handle or the dimen-
sions of the coil and handle, or the manner in which the tube shall be placed on the
handle.
Furthermore, I do not confine myself to the manner in which the tube shall
be attached to the handle or the degree to which the tube shall be inflated, or the
number of chambers which may be contained in the tube which surrounds the
handle, and that if in practice it is found desirable, a covering or envelope of
any desired character may be placed over the inflatable covering for the handle.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is
1. A handle for a tool or handle bar for a bicycle provided with a coiled flat-
able cushion, the said cushion serving as a grip for the operator, substantially as
shown and described.
2. The combination with the handle of the handle bar for a bicycle or fie
handle of a tool, of an inflatable tube wound around the said handle and pro-
vided with a valve at one of its ends, whereby the said tube may be inflated, as and
for the purpose specified.
3. The combination with the handle of the handle bar of a bicycle or the handle
of a tool, of a tube attached at one end to the said handle and wound spirally
thereon, the opposite end of the tube being provided with a valve, and a clamp
holding the valved end of the tube to the said handle, as and for the purpose set
forth.
4. The handle of a handle bar for a bicycle or the handle of a tool, having a
reduced surface and an inflatable tube secured to the said reduced surface near one
end and wound spirally around said reduced surface, the opposite end of the tube
terminating in a valve and a clamp engaging with the valved end of the tube
and with the handle, holding the valved end of the tube upon said handle in a
fixed position as and for the purpose specified.
