PROVISIONAL SPECIFICATION.
An Improved Manufacture of Frames and of other Hollow or Solid
Parts of Velocipedes.
I, WILLIAM REGINALD RIDINGS, of Derby Road, Weaste, Salford, in the
County of Lancaster, Electrician, do hereby declare the nature of this invention to
be as follows:-
My invention relates to an improved manufacture of frames and of other hollow
parts of velocipedes and comprises improvements in frames, or solid handle bars,
saddle pins, rims gear cases and other parts of velocipedes which are constructed of
electrically-deposited metal in the manner set forth in the Specification of British
Letters Patent No. 1715 dated 25th January 1893.
It is well known that some portions of the frame and of other parts of a
velocipede require to be made stronger than other portions thereof, for instance,
such portions as are exposed to wear or which bear the greatest stress.
According to one part of my invention I provide for strengthening portions of
the frame and of other parts of a velocipede without altering the external
dimensions or appearance thereof. I do this in the manner following, that is to
say, I secure to the mould or matrix on which the metal is to be deposited a liner
or strip or other suitably shaped piece of steel or other metal. Said liner or
strengthening piece is so situated as to strengthen the deposited metal where
required. The metal is deposited on the matrix in the usual manner and also on
the liners or strengthening strips which thereby become firmly united to the deposit
and remain incorporated therewith when the matrix is melted out.
The liners or strengthening strips may be made of steel tempered and hardened if
desired.
In some instances I provide a wearing part which is intended to be exposed on
the outside of the deposited metal. Such wearing part would in general be of
harder metal than the deposit which forms the other portion of the piece and is
conted with non-conducting varnish or arranged so that no metal will be deposited
thereon. Wearing surfaces of this description may be made of hardened steel.
By another part of my invention I provide an improved form of gear case.
Said
case is made with one portion thereof, the upper portion preferably, adapted to
slide in suitable guides on the lower portion so that when desired the chain can be
inspected without trouble. I provide a suitable catch or fastening to prevent the
accidental opening of the case.
When such a case is made according to my improved method that is to say by
depositing the metal electrically, the guides or slides are strengthened with steel
or other suitable strips to form the wearing surfaces in the manuer hereinabove
indicated.

page_text: An Improved Manufacture of Frames and of other Hollow or Solid
Parts of Velocipedes.
I, WILLIAM REGINALD RIDINGS, of Derby Road, Weaste, Salford in the
County of Lancaster, Electrician, 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 manufacture of frames, handle bars, saddle
pins, rims, gear cases and other parts of velocipedes, which parts whether solid or
hollow are constructed of electrically-deposited metal in the manner set forth in
the Specification of prior Letters Patent No. 1715 dated 25th January 1893.
It is well known that some portions of the frame and of other parts of a
velocipede, for instance those portions that are exposed to wear or that bear the
greatest stress require to be made stronger than other portions thereof. One part
of my invention provides for meeting this requirement without altering the external
dimensions or appearance of the parts. I do this in the manner following, that is
o say. before depositing the metal I attach to the mould or matrix in the required
position a suitable liner or strip and I then deposit the metal on the matrix and
also on the liner or strengthening strip which thereby becomes firmly united to the
deposit and remains incorporated therewith when the matrix is melted out.
to
In order that my invention may be clearly understood I will now describe the
same with reference to the accompanying drawings, in which,
Figure 1 is a central section of portions of the "diamond" frame of a velocipede
constructed according to my invention, parts thereof being shown broken away.
Figures 2 and 3 are sections taken on the lines, and y, y respectively, of
Figure 1.
-
Figure 4 is a front elevation of the crank-axle bearing shown in central vertical
section in Figure 1.
Figure 5 is a side elevation of a liner for the front fork.
Figure 6 illustrates a blank from which the liner is made.
Figure 7 is a side elevation of my improved gear-case.
Figures 8, 9 and 10 are detail views to be hereinafter described.
Like letters denote corresponding parts throughout the drawings.
A, A are liners, B, B are strengthening strips, C is the electro-deposited metal.
The liners A and strengthening strips B of which there may be two or more in
one part of the frame are advantageously made of steel.
In some instances I provide a wearing part D that is intended to be exposed on
the inside or outside of the deposited metal C. Such a part D would in general
be made of harder metal than the deposit C. that forms the other portion of the
piece and would be coated with non-conducting varnish or otherwise prepared or
protected so that no metal is deposited thereon: I preferably make the wearing
part of hardened steel.
To make the liner shewn in Figure 5 I take a cross-like blank such as that
shown in Figure 6 and bend the arms B', B₁ thereof upward and the other
arms B, B, thereof downward. The arms B' are then bent or rounded to enter
and fit the socket tube of the steering head.
The second part of my invention is illustrated by Figures 7 to 10 and relates to
an improved gear case of which one portion, preferably the upper portion E is
adapted to slide in suitable guides F, (Figures 9 and 10) secured to the other
portion E so that when desired the gear chain can be readily and quickly
inspected. The said guides F, are formed by angle shaped strengthening or
wearing strips (Fig. 8) secured to the case in the process of depositing the latter,

These pieces are bent subsequently to a U-shape to form grooves as shown in
Figures 9 and 10. The upper half E of the case is bent over at its lower edge to
engage with and to slide in the said guides F, as indicated in Figure 10.
instances the guides will be formed by the deposited metal. The line e Figure 7
indicates the upper edge of the part E of the case.
I provide a suitable catch or fastening to prevent the accidental opening of
the case.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the manufacture of frames, handle bars, saddle pins, rims, gear cases, and
other parts of velocipedes by electro-deposition, incorporating with the mould or
matrix, a liner or strengthening strip, or a wearing strip, or two or more such strips,
substantially as, and for the purpose, specified.
2. The gear case having one portion thereof constructed to slide in guides on the
other portion, which guides are preferably formed by wearing strips, substantially
as described, and for the purpose specified.
