PROVISIONAL SPECIFICATION.
A New or Improved Method of Welding or Joining the Ends of Flat
Steel Strips for Making the Rims of Cycles and the like Wheels.
I, ALEXANDER ROBERT BUNTING, of County Steel Works, Sheffield, Steel Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
My present Invention relates to the joining together the ends of Steel strips by
means of welding, the object being to obtain a strong reliable and practically
solid joint superior to the brazed joints in ordinary use.
In carrying my invention into practice I proceed in the following manner: i.c.,
I take a strip of steel or iron of a proper section and of suitable length to produce
a rim of the required diameter and curve the same approximately to a circle, the
two extremities being well cleaned are bent to curves or angles and are brought
into close contact at one point or line only so as to leave or form a space between
the faces to be heated, the parts of the strip may be secured against movement
by means of suitable blocks or clamps, the ends are now simultaneously raised to
a welding heat by a flame of water or other gas applied by means of a suitable
blow pipe and the operation is completed by rapidly moving the strip across to a
press or drop stamp which by pressure completes the weld. When cleaned off
and trimmed the strip is ready for finishing to any shape of rim required.

A New or Improved Method of Welding or Joining the Ends of Flat
Steel Strips for Making the Rims of Cycles and the like Wheels.
I, ALEXANDER ROBERT BUNTING, of County Steel Works, in the City of Sheffield,
Steel 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 present Invention relates to the joining together of the ends of steel strips
by means of welding, the object being to obtain a strong reliable and practically
solid joint, stronger and superior to the brazed joints in ordinary use."
In carrying my invention into practice I proceed in the following manner: I
take a strip of steel of a proper section and of suitable length to produce a rim of
the required diameter and curve the same approximately to a circle the two
extremities being well cleaned are slightly curved or bent so as to not touch all
[Price 8d1

page_text: along the overlaying faces, said ends may be simply rivetted together or be
secured against movement by means of suitable clamps or tongs, the joint is now
placed upon a bed over a block of hot refractory material and is subjected to a
Hame of water or other gas mixed with air under pressure applied by means of a
suitable blow pipe apparatus until raised to a welding heat, the operation is then
complted by rapidly moving the hot strip across the bed to a beaked projection
where pressure is applied to close the joint and thereby perfect the weld.
This part of the operation may be performed by means of a press, stamp, or
simply by the workman with his hammer. When cleaned and trimmed the hoop
is ready for finishing to any shape of rim required.
That my invention may be better understood, I will now explain it further by
reference to the Sheet of Drawings annexed hereto as illustrating one form of
apparatus adapted for closing the weld by a hand hammer.
-
Fig. 1 is a side and Fig. 2 is a front Elevation of apparatus both views having
the gas supply pipe away. Fig. 3 is an example of ends jointed ready for heating.
The process of working is as follows:-Gas and air in suitable proportions
having been mixed and compressed by any convenient means (not shown) is con-
ducted by pipes to an inlet P, and allowed to issue by an orifice O, formed
in a nozzle piece N, which is either made of or protected by refractory material
or composition, the gas issuing therefrom having been ignited is allowed to play
upon a block B, which may be a good fire brick or any other good heat resisting
substance, so soon as said block B, has attained a sufficient degree of heat the thin
material S, to be welded is placed upon the block B, in the position shown until
the requisite degree of heat has been attained whereupon it is quickly drawn
forward upon the beak iron A, where by rapid, blows of an ordinary smith's hand
hammer may be closed and completed.
If preferred mechanical means may be used for closing and completing the weld,
such mechanical means forms no part of my invention and do not affect the quality
of the resultis.
The dimensions and shape of the orifice O, in top nozzle N, as also the distance
apart of N from B will require to be varied to suit different classes of work.
The supply of compressed gas and air is also to be regulated by the stop tap R,
or other equivalent means.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare what
I claim is: -
The combination mode or process of welding thin strips of Steel by means of a
flame of mixed gas and air emitted under pressure, substantially as herein described.
