Improvements relating to Bicycles and the like.
I, PETER GENDRON; of 1413 Walnut Street, in the City of Toledo, Lucas
County, State of Ohio, United States of America, Manufacturer, do hereby
declare the nature of my 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 in the peculiar construction of the handle bar, and in a
clamping ring for holding the adjustable parts firmly in their adjusted positions.
Further, in the peculiar construction, arrangement and combination of the various
parts all as more fully hereinafter described.
In the drawings,
Fig. 1 is a perspective view of my handle bar.
Fig. 2 is a horizontal section through one half thereof.
Fig. 3 is an enlarged elevation of one of the grips.
Fig. 4 is a cross section on line .. Fig. 2.
In the manufacture of bicycles, one size of frame is made for men and another
for boys, and these are adapted to men or boys of different sizes by means of
adjustments. These adjustments usually comprise a vertical adjustment of the
seat and a vertical adjustment of the handle bar. Handle bars are made of a
uniform length. A handle bar of suitable length for a narrow chested man would
cause a broad-shouldered man to assume an uncomfortable and unhealthy position,
and vice versa.
The same is true of the forward and back adjustments of the
handle bar, they are arranged rigidly and no suitable provision made to adjust
them to long-armed or short-armed men.
The object of my invention is to provide these adjustments either singly or
together. Further to provide a clamp for the adjustments which will effect a
perfect clamping and in which the movement of the clamping lugs cannot spring
the bolt.
A is the steering head, on the top of which the handle is supported, being
connected thereto in any desired manner. My handle comprises a central section
or head B supported centrally on the steering head, and end sections C having a
portion D extending parallel with the head, and a portion E extending substantially
rearwardly therefrom, preferably formed by beuding.
The end sections are adjustably secured to the ends of the heads, so that the
length of the handle bar may be adjusted as desired. This adjustment I prefer-
ably accomplish by making the head B of tubing, and splitting the ends thereof,
inserting the ends of the portion D of the extensions telescopically therein, holding
them in their adjusted positions by means of the clamping ring F. This con-
struction enables me not only to adjust the extensions inwardly and outwardly,
but also rotatorially, in relation to the head._
The handle grips are secured to the ends of the end extensions, and may be of
any suitable construction, that which I prefer consists of a tube G, having a
covering H over a sufficient part of its surface to give the usual handle, and having
the free end split, and provided with a clamping ring I. This grip may be slipped
on the end of the extension E, adjusted thereon as desired, and clamped at any
adjusted position. My clamping ring consists of a substantially U-shaped body.J,
the inwardly extending lugs K having curved inner faces.
The legs of the body extend beyond the lugs K and are apertured to receive
the bolt L. These apertures are preferably tapered, or may be made simply
large enough to allow the bolt to assume an angular position in the lugs without
binding. The outer faces of the lugs are provided with concave bearings M. The

page_text: bolt head N and the nut are provided with corresponding convex faces, so that
in screwing up the bolt, the nut and head will always have a wide bearing, no
matter what angle the bolt may assume. This prevents any possibility of bending
the bolt in use. The lugs K for an unyielding connection between the clamping
lugs and the ring, so that the lugs cannot bend the ring alone bending and effecting
a clamp about the entire circumference.
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. In a bicycle, the herein described longitudinally extensible handle.
2. In a bicycle, the handle bar having extensible hand grips thereon.
3. In a bicycle, the herein described longitudinally extensible handle bar having
rearwardly bent ends, and the extensible hand grips thereon.
4. In a bicycle, the handle bar formed of a tubular head having split ends, end
extensions telescopically engaging therein, having rearwardly bent ends, and hand
grips consisting of a tube provided with hand holds having split ends and a clamp,
substantially as described.
