PROVISIONAL SPECIFICATION.
A Double Diamond Frame for Safety Bicycles or other Cycles.
I SAMUEL VALE of Ablewell Street Walsall in the County of Stafford, Bicycle &
Tricycle Manufacturer do hereby declare the nature of this invention to be as
follows:-
1 purpose making my frame of steel tubes or other suitable materials.
The tubes are carried along each side of machine and round the front of steering
post, which carries the top part of neck, and also from the bottom bracket round
front of steering post which carries bottom part of neck and from the bracket to the
centre of hind wheel, and from centre of hind wheel to the point under sadrile and

improves the steering, and also enables me to use a foot break in connection with my
patent No. 16064, 1886.
COMPLETE SPECIFICATION.
A Double Diamond Frame for Safety Bicycles or other Cycles.
I SAMUEL VALE of Ablewell Street Walsall Bicycle and Tricycle 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 invention or improvements consists of a new method in the construction of a
cycle frame and may be briefly described as follows.
Fig. 1 represents top view of frame and Fig. 2, side view, in the two figures the
same letters indicate the same parts.
It consists of a tube (marked A in the drawing) running horizontally from the
seat pillar B round steering or front pillar C through neck or centers 1 placed in
front of steering pillar, and back to seat pillar B on other side and tube from seat
pillar B to hub of back wheel E on the other side, a tube or tubes running from bub
of back wheel E to bracket or crank action, F on each side, and another tube or tubes
from bracket F: to seat pillar B on each side, and another tube or tubes from
bracket F. round front of steering pillar C. through the neck or centers G. which is
placed in front of steering pillar Cand back again to bracket on other side at F.
thus making a double diamond frame through with steering in front of the pillar,
insted of the usual way at back thus making the machine much easier to steer, and
is applicable to safety bicycle, tricycles, or other vehicles.
The object I have in view is to add to the strength of frame, improve the steering,
and at the same tine reduce the weight, the whole of the frame may be made in one
or more pieces of tube or other suitable materials and may be either bolted, brazed,
or screwed togeather as may be deemed suitable, with additional stays or pillars, as
may be necessary.

claim is.

hundred and ninety.
