Improvements in the construction of Rear Axle Supports for Bicycle
Frames and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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:-
The annexed drawings and the following description set forth in detail, one mode
of carrying out the invention; such specific mode being but one of various ways in
which the principle of the invention may be used.
In said annexed drawings,
Figure I represents a view of one end of one of the tubular braces forming the
rear axle support;
Fig. II, an axial section of said brace ;
Fig. III, a view of the slotted plate in which the rear axle is adjustably supported;
Fig. IV, a side view of the support after the parts are welded together; Fig. V,
an edge view of the same, and
Fig. VI, a side view of the finished support.
The steel tubes which form the braces A and A', of the rear fork, have their
ends flattened so as to form flat webs, a and a', at the ends of the tubes. The slotted
plate B, in which one end of the axle of the rear. bicycle wheel is adjustably
supported, is formed with a vertical edge, b, and an incline upper edge, b. In
assembling the parts of the support, the horizontal brace A, and the inclined brace A',
are placed with the edges of their flat webs a and a!, respectively against the
edges 6 and 6, of the slotted plate, and the edges of the webs and plate are then
welded by means of an electric welding machine. The webs of the tubes and the
plate thus form an integral part, and the raised fins, c and c', formed at the joints
by the welding process, are removed by cutting, grinding, filing, or other similar
process, when the surfaces of the webs and plate will appear as if formed from one
integral piece of steel. A very strong and simple union of the parts of the support
is thus made, which dispenses with riveting, brazing, lap-welding by fire and hammering,
and all similar more or less insecure methods of uniting the tubes to the plate.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. The improved method of forming a rear axle support for bicycles, substantially
as described and illustrated.
2. An improved support for the rear axle of a bicycle, which consists of a slotted
plate in which the axle of the rear wheel is supported, and tubular braces having
their ends flattened to form webs and having the edges of said webs secured and
united to the edges of said plate by electric welding, substantially as set forth.
Dated this 24th day of June A.D. 1896.
