Velocipedes.
I, GEORGE SINGER of Alma Works, Coventry in the County of Warwick,
Bicycle and Tricycle: Manufacturer, do hereby declare the nature of said
invention for "IMPROVEMENTS IN THE FRAME WORK OF TRICYCLES AND OTHER
VELOCIPEDES."
The object of this invention is to attain a maximum amount of rigidity com-
bined with a minimum amount of weight in the frame work of tricycles and other
velocipedes. The invention is chiefly intended for that class of tricycle which has
the two driving and steering wheels on a main axle and a backbone with small
trailing wheel in the rear but it may also be used in connection with backbone
fixed to the main frame and with back steering wheel.
According to this invention I provide over the main axle and connected to the
bearings a curved tube or tubular structure forming together with the main axle
a bowstring girder. On this curved tube I fit a hollow fork with preferably a
"Stanley or close centre head as used for the front wheel of a bicycle.

page_text: The invention is chiefly intended for that class of tricycle which has the two
driving and steering wheels on a main axle, and a back bone with small trailing
wheel in the rear; but it may also be used in connection with tricycles having
back bone fixed to the main frame, and with back steering wheel;
According to this invention I provide, over the main axle and connected to the
bearings, a curved tube or tubular structure, forming, together with the main axle
a bow string girder.
On this curved tube I fit a hollow fork with; preferably, a "Stanley" or close
centre head as used for the front wheel of a bicycle.
In order that my invention may be fully understood.I will proceed to describe
the same with reference to the accompanying drawings.
.
Figure 1 is a side elevation with one of the front wheels removed, and shewing
the main axle and cross tube, in section, of a Tricycle of the so called "Humber
type, constructed according to my invention; and Figure 2 is a front elevation of
the same machine.
A is the curved tube or tubular structure; B is the main axle; C C are bearing
boxes on the main axle B, and connecting the main axle B with the curved or
tubular structure A; the whole forming a bow string girder; D is the fork through
the two sides of which the curved tube A passes. The ends of the fork are shewn
as carrying two bearing boxes marked E E¹ connected together by a curved bar E.
The bearing boxes C C and E E¹ may also be connected by a light tie rod.
Although I have only shewn the invention as applied to a Tricycle of the well
known "Humber" type, yet the same is applicable to other velocipedes.
The other parts of the machines require no further description.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:
In Tricycles and other velocipedes, the curved tube or tubular structure A, the
main axle B, the bearing boxes C, forming together a bowstring girder, in combina-
tion with the bifurcated fork D, and parts connected therewith: all substantially
as, and for the purposes described with reference to the accompanying drawings.
Dated this Sixth day of April 1886.
