Improvements in the Construction of Tricycles and like Velocipedes.
We, MARRIOTTS' LIMITED, of 71, Queen Street, in the City of London, and
Hay Mill, Birmingham, in the County of Warwick, Manufacturers, and JAMES
DOWNING SPENCER, of 709, Coventry Road, Birmingham aforesaid, Works
Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of tricycles and
like velocipedes and has for its object to provide an improved arrangement for
driving such machines by centrally arranged driving gear.
For this purpose we fork the front tube and the seat stay of the frame of the
machine and we make the bottom stay double, the space between the legs of the
forks and that between the double bottom stay being sufficient to allow of the inser-
tion of the chain wheels, chain and, when required, of the gear case.
It will be obvious that this construction is applicable both to gentlemen's and
ladies' machines.

Hay Mill, Birmingham, in the County of Warwick, Manufacturers, and JAMES
DOWNING SPENCER, of 709, Coventry Road, Birmingham aforesaid, Works

same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to improvements in the construction of tricycles and
like velocipedes and has for its object to provide an improved arrangement for
driving such machines by centrally arranged driving gear.
For this purpose we fork the front tube and the seat stay of the frame of the
machine and we make the bottom stay double, the space between the legs of the
forks and that between the double bottom stay being sufficient to allow of the inser-
tion of the chain wheels, chain and, when required, of the gear case.
In the accompanying drawings:
Figure 1 is a side elevation of the frame of a gentleman's tricycle construction
according to the invention :

page_text: Figure 2 is an end view thereof; and
Figure 3 is a perspective view of a similar frame drawn to a smaller scale.
a is the front tube, the lower portion of which is forked as shewn at a¹, a¹;
6 is the seat stay, the lower portion of which is also forked as shewn at b¹, b¹, and
c, c is the double bottom stay, the two legs c, e of which are secured to the junc-
tions of the lower ends of the forks a¹, band to the tube d to which the rear
tubes e, e of the frame are secured and which carries the rear axle.
The spaces between the legs a¹, a¹; b, b¹ and c, care, as above mentioned,
sufficient to permit of the insertion of the chain wheels and chain and of the gear
case when such is employed. The rear parts c¹, c¹ of the tubes c are, as shewn,
cranked to provide a larger space between them for the reception of the gear
box f.
It will be obvious that this construction of frame is applicable to ladies' as well
as to gentlemen's machines and that it is also applicable to the convertible ladies'
and gentlemen's machine described in the Specification of our former Patent
No. 6035 98.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
1. A tricycle or like frame wherein the front tube and the seat stay are forked
at their lower ends and wherein the bottom stay is made double substantially as,
and for the purpose hereinbefore described and as illustrated.
2. The manufacture and use of the improved tricycle frames, hereinbefore
described and illustrated in the accompanying drawings.
