Improvements
Year: 1897

page_text: I, DAVID HENRY Guest, of 87, City Road, Manchester, Cycle Manufacturer, do
hereby declare the nature of this invention to be as follows:-
-
My said invention relates to improvements in or applicable to the handle bars
of cycles.
According to my said invention the centre part of the handle bar forms a cross-
head containing two hinge pins, on which are hinged the right and left hand
sections of the handle bar. This enables the sections of the handle bar to be folded
downwards so as to lessen the total width as compared with a rigid handle bar.
In order to secure the sections of the handle bar in their working position a central
bolt is provided having a collar or head which bears against the adjacent portions
of the handle bar sections.
In order to prevent the central bolt being entirely withdrawn when the sections
of the handle bar are released a pin or plate taking into a corresponding recess in
the bolt is provided.
In order to provide means for altaching a luggage carrier, lamp bracket, or
similar object the hinge bolts are perforated in the direction of their length so
as to receive corresponding pins or bolts on the article to be secured to the handle
bar.

Improvements in or applicable to the Handle Bars of Cycles.
I, DAVID HENRY GUEST, of 87, City Road, Manchester, Cycle 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 said invention relates to improvements in or applicable to the handle bars of
oycles.
The object of my invention is to construct a handle bar having two sections
hinged by hinge pins or bolts to the central part of the handle bar which forms a
crosshead so as to enable the two sections forming the handle bar to be folded
downwards when desired as for instance to enable the cycle to pass through or
remain in narrow passages and also for convenience in transit or storage.

page_text: In order that my said invention may be more clearly understood I will describe
the same with reference to the accompanying drawing in which
Fig. 1 is a front elevation of a handle bar constructed in accordance with my
said invention.
Fig. 2 is a plan of same.
Fig. 3 is a front elevation showing the handle bar in a folded position.
Fig. 4 is a section through of Fig. 3.
Fig. 5 is a plan showing part of the right hand section of the handle bar.
According to my said invention the centre part a of the handle bar forms a cross-
head containing two hinge pins or bolts bh on which are binged the right and
left hand sections C and D forming the handle bar. This enables the sections
C and D of the handle bar to be folded downwards. in the direction of the
arroway (Fig. 1) until it assumes the position shown at Fig. 3. In order to
secure the sections C and D) of the handle bar in their working position as shown
at Figs. 1 and 2 a central bolt is provided having a collar or head c' which is
caused by the rotation of the bolt a to bear against the adjacent portions C' D' of
the handle bar sections. The said portions C₁ D' of the handle bar sections are
formed with semicircular recesses d (Fig. 5) in order to allow the bolt c to move
therein. The head of the bolt c is preferably formed hexagonal as shown at
with a projecting milled edge ³ so as to enable the bolt c to be rotated either by
hand or by a screw key or spanner.
In order to prevent the central bolt c being entirely withdrawn when the
sections CD of the handle bar are released (see Fig. 4) the threaded portion of of
the bolt & engaging with the plate e is provided with a washer or collar which
is held in position by means of a pin passing through the bolt c or otherwise.
In order to provide means for attaching a luggage carrier, lamp bracket, or
similar object the two hinge pins or bolts bb passing through the crosshead a are
in one form of my said invention perforated in the direction of their length as
shown at 6 so as to receive corresponding pins or bolts on the article to be secured
to the handle bar.
I am well aware that various constructions of folding handle bars have been pro-
posed to be used and I wish it to be understood that I make no general claim
thereto.
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. A collapsible handle bar for cycles substantially as and for the purpose set
forth and shown.
2. A collapsible handle bar having hinged handles held in position by a central
clamping bolt and capable of being depressed when the clamping bolt is raised
substantially as and for the purpose set forth and shown.
3. A folding handle bar for cycles consisting of two hinged sections C and D
hinged on bolts to the centre part or crosshead a of the handle bar and having a
rotatable clamping holt c for securing the two sections C and D in position sub-
stantially as and for the purpose set forth and shown.
4. In a collapsible handle bar the combination with the folding sections C D of
hollow hinge bolts bb substantially as and for the purpose shown.
