PROVISIONAL SPECIFICATION.
Improvements in and Connected with the Brake Gear and
Framework of Velocipedes.
I, THOMAS RICHARD DEVEREUX BINGHAM, of Wartnaby Hall, Melton
Mowbray in the County of Leicester, Retired Captain Bengal Lancers, do hereby
declare the nature of this invention to be as follows:-
My invention relates to an improved arrangement of brake gear and framework
for velocipedes particularly applicable to that type of machine wherein double
tubular parallel frames are employed and such as are described in the Specification
of my Patent application dated 3 February 1890 No. 1826, all as hereafter
described.
The brake is mounted on a spindle between and carried by the parallel frame
tubes and is situated somewhat to the rear of the crank axle mounting, and acts on
the rear wheel of the machine to which it is applied. The brake may be conveniently
of spoon type and the spoon is situate above the centre on which it is mounted while
the lever part is below the centre; a convenient way of carrying the brake and
crank spindle without breaking the continuity of the frame is by means of sleeve
lugs on the parallel tubular framework. There is a rod from the lever part of the
brake passing between the tubular frames to the handle bar where it is connected
in any convenient manner to the operating lever, for example this rod may be
connected to one arm of a two armed lever fulcrummed centrally to the handle bar
and this lever may be operated by an ordinary operating lever having a vertical
action. The tubular parallel frames are made of approximately elliptic form curved
or flattened at their extremities and composed of an upper pair of tubes carrying
the rear wheel between them. The rear ends of these tubes are brazed to the rear
wheel bearings and continue in one length to the front, where they are brazed to
the steering socket or centre, the lower tubular parallel frame is of similar con-
struction but curved in the opposite direction to the upper members.
There is a bracket, preferably a "cross girder," on the upper frame for carrying
the seat pillar and from this bracket there are one or more stay rods to the lower
frame. By the above arrangement a continuity of tubing, almost without joints,
by brazing or otherwise and consequently strength obtained in a machine of this
type, together with a brake applied in an effective and powerful manner and in such
a position that it does not get in the rider's way, or throw up, or splash the dust or
mud and is in itself of most simple and inexpensive construction.

Improvements in and Connected with the Brake Gear and
Framework of Velocipedes.
1, THOMAS RICHARD DEVEREUX BINGHAM, of Wartnaby Hall, Melton
Mowbray in the County of Leicester Retired Captain Bengal Lancers 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 an improved arrangement of "brake gear" and frame-

page_text: work for velocipedes particularly applicable to that type of machine wherein
"double tubular parallel frames" are employed, and such for example as are
described in the Specification of my Patent application dated 3 February 1890
No. 1826 all as hereafter described.
My invention will be clearly understood by the following description referring
to the accompanying drawings
Figure 1 showing a side elevation of a bicycle of "Safety" type constructed
according to my said invention,
Figure 2 being a detached plan view of the brake lever and adjacent frame
tubes, and
Figure 3 a similar detached plan view of the seat pillar support and "girder"
bracing.
According to my invention the brake lever A is mounted on a spindle or axis B
situated between and carried by the lower parallel frame tubes CC and is arranged
somewhat to the rear of the crank axle D'and is to act on the rear wheel E of the
machine when applied. The acting part of brake A may be conveniently of
spoon type and the spoon is situate above the centre B on which it is mounted
while the lever part is below the centre and I preferably make the bearing surface
of the spoon nearly flat, it being "shod" with a steel rubbing piece; a convenient
way of carrying the brake A and crank axle D without breaking the continuity of
the frame CC is as shown by means of sleeve lugs C2, C3, D' D' on the aforesaid
parallel tubular framework.
There is a rod F from the lever part of the brake A passing between the
tubular frames C C to the handle bar G, where it is connected in any convenient
manner to the operating lever H, for example this rod F may be as shown at
Figure 1 connected to one arm of a two armed lever J fulcrummed centrally
to the handle bar and in a direction transversely thereto and this lever J may be
operated by an ordinary operating lever having, as is now common to "Safety'
bicycles, a vertical action, so that when the outer end of the operating lever
is raised by the hand of the rider the inner end of same will depress the outer
arm of the lever J and raise the opposite arm which will lift the rod F and
apply the brake spoon to the wheel, the arrangement of the said brake spoon
being such in machines constructed according to my invention that the application
to the wheel takes place in the most advantageous manner, that is, the brake
spoon acts oppositely or reversely to the direction of motion of the wheel. The
tubular parallel frames are made of approximately elliptic form curved or flattened
at their extremities and are mainly composed of a lower pair of tubes C C, and
an upper pair of tubes C1 C', the latter carrying the rear wheel E between them.
The rear ends of the tubes C' C' are brazed to the rear wheel bearings and
continue in one length to the front of the machine where they are brazed to the
steering socket or centre as the case may be.
The lower tubular parallel frame CC is of similar construction, but curved in
the opposite direction to the upper members C¹ C¹ aforesaid.
There is a bracket preferably a "
cross girder" on the upper frame C¹ C¹, for
carrying the seat pillar L. M Fig. 3 is the "cross girder" distancing bracket,
which may be brazed direct between the frames or may be fitted thereto by means
of ferrules as are the brake lever bearings, it being an important feature in the
herein described machine to maintain the frame continuous, so as to form as nearly
as possible a homogeneous structure, and from near the bracket M there are one
or more cross stay rods or tubes P to the lower frame C C. It will be evident
that cross girder" distancing brackets such as M may, if desired, be employed at
suitable intervals to couple the parallel frames C C and C¹, C'; the stay tubes P
preferably are in pairs parallel to each other.
By the herein described construction and arrangement a continuity of tubing,
almost without joints, by brazing or otherwise and consequently strength, is obtained
in a machine of this type together with a brake applied in an effective and powerful
manner and in such a position that it does not get in the riders way or throw

page_text: up or splash the dust or mud and is in itself of most simple and inexpensive
construction.
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 velocipedes, especially those of "Safety" type, the brake lever A mounted
on spindle or axis B, carried by sleeve lugs between parallel tubular lower frame,
and situated near crank shaft the spoon of said brake acting oppositely or reversely
to the direction of motion of the rear wheel and being operated by connecting
rod and devices from handle bar of machine all arranged constructed and acting
substantially as and for the purposes herein set forth with reference to the accom-
panying drawings.
2. In velocipedes, the combination with the arrangements claimed in the preceding
claim, of the approximately elliptical parallel tubular framework composed of upper
and lower parallel members C C C C with "cross girder" distancing brackets M
and stay tubes P all substantially as described and illustrated with reference to
the accompanying drawings.
3. The general arrangement construction and combination of parts comprising
my improvements in and connected with the brake gear and framework of
velocipedes all substantially as and for the purposes described and illustrated with
reference to the accompanying drawings.
Dated this 15th day of Apríl 1891.
