COMPLETE SPECIFICATION.
Improvements in Bicycles.
We EMIL DÖRING, Engineer, and FRIEDRICH AUGUST SIEGERT, Merchant, both of
Weistropp near Wilsdruff, in the Kingdom of Saxony, do hereby declare the nature of
our said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Whereas it is the common practice, when bicycles are at rest, to retain them in a
nearly vertical position by leaning the same against trees, hedges, or walls; or two or
more bicycles are placed together so as to mutually support each other; and in the
absence of such means of support, the bicycle is sometimes placed flat upon the ground,
whereby the lacquerd or nickeled parts are liable to be scratched and otherwise
damaged and rendered unsightly.
Now the object of our invention is to provide means whereby bicycles may be
caused to stand alone, in an erect position, when stationary.
In carrying out our invention we fit the bicycle with two iron rods or legs, united
at their upper ends, to the bicycle and to each other by means of a spring, which has
a tendency to spread the lower ends of the rods outwards, and thus form points of
support on each side of the wheel base.
And in order that our said invention may be particularly described and ascertained
reference is hereby made to the accompanying Drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a transverse view of the iron rods. Fig. 2 is a side view. Figs. 34 and 6
are detail views. Fig. 5 is an elevation showing the application of our invention to a
safety bicycle, and Fig. 7 is a transverse view of the same.
e. e¹ are the two rods, pointed at their lower ends, and furnished with discs xx to
prevent their sinking in soft ground. The upper ends are bolted to the spring k by
holts and nuts s s. One end of a curved rod d is fixed to the rod e, the other end
passing through a hole in the rod e¹ and being fitted with a knob to limit the radial
motion of the rods e e¹. The spring head k is fixed to the back boner by means of a
tab z.
a is a stay rod secured, at its lower end, to the fork of the treadle axle, and,
at its upper end, to the tab z, with a screwed nut m (shown enlarged in Fig. 6).
To prevent the wheels moving or starting when the bicycle is supported by the
rods e el, a spiral spring fis fitted at the end of the brake bar b, such end being spoon
shaped; one end of the spiral spring being fixed to the handle bar. This spiral spring
acts upon the brake bar b so as to apply the brake to the rubber tyre of the front
wheel, and thus effectually prevent the bicycle from moving in any direction. The
position of the rods e e', when the bicycle is stationary, is shown by solid lines in
Figs. 5 and 7. When the bicycle is again required for use, the two rods e el are
pressed together and forced into the wire clamp t, as shown by dotted lines in Fig. 5.
A side view of this clamp is shown in Fig. 5; a plan view of the same is shown in
Fig. 3, and a back view of the same in Fig. 4. This clamp is secured to the treadle
fork, and the rods e e' may be securely held therein while the bicycle is being driven,
without offering the least obstruction to the movements of the rider.
The chains and chain wheels have been omitted from the drawings for greater
clearness.
The foregoing description and drawings illustrate the application of our invention to
a safety or Rover bicycle, but it is obvious that, with suitable modifications, it may be
applied to other forms of bicycles.
Having now particularly described and ascertained the nature of our said inven-
ion, and in what manner the same is to be performed we declare that what we
claim is :-
1 A

page_text: position when at rest, such device consisting of two iron rods or legs e e¹ attached to
the back bone or other part of the frame by a spring k, arranged to extend the lower
ends of the rods when released from the clamp t, substantially as hereinbefore
described and illustrated by the drawings.
2. The application and use of a spring operating upon the spoon shaped end of the
brake bar, and so arranged that the brake is thereby applied to the front wheel, when
at rest, substantially as and for the purpose hereinbefore described and illustrated by
the drawings.
3. The general construction, combination, and arrangement of the several and
respective parts, together constituting our invention of improvements in bicycles,
substantially as hereinbefore described, and illustrated by the drawings.
