IMPROVEMENTS IN VELOCIPEDES
Year: 1885

page_text: I JAMES RICHARD TRIGWELL, Merlin Engineering Works, Brixton Rise in' the
County of Surrey, Engineer do hereby declare the nature of this my invention for
IMPROVEMENTS IN VELOCIPEDES to be as follows:-
I.
My Invention is for improvements in Velocipedes and relates particularly to
that part called the Handle-bar, which is designed so as to do away with vibration
on the bands when travelling over rough roads.
It is constructed on the following method which I particularly claim as, my
invention. The Handle-bar is made in three pieces, the centre piece of which is
fixed on the head; the two outside or handle pieces are connected to the former by
any form of hinge which would keep these handle ends rigid with the centre part
except for a downward movement.
These handle ends are kept up in their position by means of a spring (of india-
rubber; steel coil or otherwise) which allows the handle ends to yield to the
oscillation of the machine.

I JAMES RICHARD TRIGWELL of the Merlin Engineering Works Brixton Rise in
the county of Surrey, Engineer; 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 :-
11.
My invention relates to the handle bars of bicycles, and other velocipedes in which
the steering is controlled by a transverse handle bar; and it has for its object the
isolation of the vibration set up by travelling over rough roads, from the hands and
arms of the rider. To attain this end I construct the handle bar in..three pieces,
two of which, forming the outer ends of the bar are alike. The centre piece is
fixed to the head, or its equivalent either directly, or indirectly, and the two outer
ends are connected to the centre piece by a knuckle jointed hinge, or any other
convenient form of hinge that will allow the end pieces a free movement down-
wards, but will keep them rigid with the centre piece in all other directions. To
keep the end pieces of the bandle bar in: position, and to control their movements,
suitable springs made of rubber, steel wire, or other suitable material, are placed
round the joints and between plates fixed, or screwed, to the end pieces of the
handle bar
:
In order that my'invention may be fully understood I will more particularly
describe it with the aid of the accompany drawings throughout the views: of which
similar parts are marked with like letters of reference.

.. Figs. 1 and 2 aré elevation and plan respectively, partly in section, showing the
construction of one of the joints of the bar. Fig. 3 is a cross section through the
joint, and Fig. 4 is a view showing the complete handle-bar fixed to the head of a
bicycle. Referring to these figures A designates the centre piece of the handle bar,
B the end pieces, provided with, T shaped, or any other convenient form of
handles C. The end pieces of the bar B are connected to the centre piece A by
knuckle joints D. E designates the springs encircling the joints, and enclosed by
caps A¹ and B¹; the former being fixed to the centre part of the bar A, and the
latter preferably mounted loosely on nuts B³ screwed on the end pieces of the
handle bar B, so that the tension of the springs E may be adjusted to give any
desired amount of elasticity.
I do not limit myself to the exact arrangement as hereinbefore described and
shown, as my invention my be carried into effect in many other ways. At the
same time I do not claim the use of jointed handle bars for the purpose of supressing
vibration broadly, as I am aware that handle bars have already been jointed to the
heads of bicycles, and controlled by springs, for this purpose; but 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 :-
First Constructing the transverse handle bar of velocipede in three pieces
hinged, or jointed, together as, and for the purpose, hereinbefore described and
shown.

page_text: Second: The method of making the ends of a handle bar flexible in a downward
direction only, by means of knuckle joints, and springs, as, and for the purpose,
hereinbefore set forth.
.
Third A handle bar for a velocipede constructed in three parts, hinged together
by knuckle, or other similar joints, in combination with the plates A¹, and B', the
nuts B, and the springs C, all arranged, and operating, as, and, for the purpose,
hereinbefore set forth.
Fourth In a handle bar for velocipedes constructed in two or more pieces, &
jointed together to allow of a free movement of the end, or handle pieces, in a
downward direction only, the movements of which are controlled by springs; the
use of the plates A and B, in combination with the nut B, for the purpose of
controlling the elasticity of the free ends of the bar, as herein before set forth.
