PROVISIONAL SPECIFICATION.
A Terminal for the Ends of the Hollow Parts of Cycle Framings.
I, CHARLES EDWARD HARRIS, Managing Director of the Simplex Manufac-
turing Company Limited, of Bishop Street, in the City of Birmingham, do hereby
declare the nature of this invention to be as follows:-
My invention relates to means for closing the open ends of the hollow parts of
cycle framings, and has for its object, a sheet metal or sheet steel terminal, cap or
closure.
Heretofore, the said open ends have been provided or fitted with cast or
malleable parts, which, besides increasing the weight of the framing of a machine
by being solid, have to be accurately shaped and fitted to the inside bore of the
open end to be closed.
By my improvements, I provide the said open ends with sheet metal caps or lids
with a slightly domed head or crown, and with an outside flange running around
the top edge or body of the same to form an abutment shoulder for the end of a
member to which the cap is fitted to come against. The said flange, which is made
the boundary edge of the crown, may be made to slightly overhang the edge
of the said tubular member thus closed, thereby giving finish to the same.
I prefer that the said cap should be made from sheet steel and be brazed into
position.
In carrying out the making of the cap, I take a blank of thin sheet metal and
fashion the same into a shallow and elongated cup, and then by means of press
tools, I upset the crown or closed top of the same into a head having a boundary
or outstanding flange.
Although I have described a dome headed terminal, yet other shapes may be
employed if desired.
Where my invention is to be applied to round hollow members, I form the cap
or closure of a like sectional figure as the said member, whilst the same has a
flanged edge at top and a dished or sunken crown.
Dated this 23rd day of January 1894.
COMPLETE SPECIFICATION.
A Terminal for the Ends of the Hollow Parts of Cycle Framings.
I, CHARLES EDWARD HARRIS, Managing Director of the Simplex Manufac-
turing Company Limited, of Bishop Street, in the City of Birmingham, 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 means for closing the open ends of the hollow parts of
cycle framings, and has for its object, a sheet metal or sheet steel terminal, cap or
closure.
Heretofore, the said open ends have been provided or fitted with cast or
malleable parts, which, besides increasing the weight of the framing of a machine

page_text: by being solid, have to be accurately shaped and fitted to the inside bore of the
open end to be closed.
By my improvements, I provide the open end of a hollow framing member with
a sheet metal cap or lid, preferably having a slightly domed head or crown, and an
outside flange running around the top edge or body of the same, to form an
abutment shoulder for the end of a member against which the cap is to come.
The said flange, which forms the boundary edge of the crown, may be made to
slightly overhang the edge of the said tubular member thus closed, thereby giving
finish to the same.
I prefer that the said cap should be made from sheet steel and be brazed into
position.
Figure 1 of the accompanying drawing represents, partly in section, and partly
in elevation, the upper portion of the front forks of a safety bicycle, with the
upper and open ends of the hollow fork members closed by separate caps or
terminals according to my invention.
Figure 2 represents an elevation of the cap separately, Figure 3 is a longitudinal
vertical section of the same, Figure 4 a topside plan, and Figure 5 an underside
plan, whilst Figure 6 is a cross section of the cap upon the dotted lines x-x
Figure 2.
a are the sides or body of the cap, a' the hollow flange, collar or shoulder, a² the
crown, and a the open mouth.
In carrying out the making of a cap, 1 take a blank of thin sheet metal, such as
represented in plan and edge view in Figure 7, and fashion the same into a shallow
and elongated cup, as represented in section and topside plan in Figure 8, and
then, by means of press tools, I upset the crown or closed top of the same into
a head, having a boundary or outstanding flange, as represented in Figures · 1
to 6.
Although I have described a dome headed terminal, yet other shapes may be
employed if desired.
Where my invention is to be applied to round hollow members, I form the
cap or closure of a like sectional figure as the bore of the said member, and with a
flanged edge at top and a slightly domed crown, as represented in plan and edge
view in Figure 9, although if necessary the said crown may be dished or
sunken.
Figure 10 represents a modified form of cap having its edge split, to admit of the
same being easily fitted into the bore of the frame member."
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, 1 declare that what
I claim is
First. A sheet metal cap, lid or closure for the open ends of the hollow parts,
or the hollow frame members, of cycles, substantially as described and set
forth.
Secondly. The improvements in the production of caps or terminals for the
open ends of the hollow parts of cycle framings, substantially as described and
set forth.
Dated this 5th day of October 1894.
