COMPLETE SPECIFICATION.
An Improved Safety Velocipede.
I, WILLIAM BLOCK, of 15 Catherinen Canal (Newsky Perspective) in the City of
St. Petersburg, in the Russian Empire, Engineer, do hereby declare the nature of my
said 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 safety velocipede, which, in consequence of the
simplicity and durability of the construction and the uniform operation of the same
through the employment of springs, is admirably adapted to overcome all the
disadvantages experienced with the safety bicycle now in use.
In the accompanying drawings,
Figure 1 is an elevation of my improved safety velocipede,
Figures 2, 2, 2 represent the spring of the steering rod in rear view, top view
and section,
Figures 3, 3b represent the bearing for the lower spring e to the saddle in rear
view and section,
Figure 4 represents the slotted sleeve b in front and top view, and
Figure 5 represents the saddle rod in longitudinal section and rear view...
My improved velocipede consists in the following, when retaining the system of
wheels employed for this class of machine.
The front and rear wheels are connected by means of a straight double tubular frame
composed of two thin tubes c the connection between the two said tubes and the
bifurcated parts or forks & Figure 1. This connection is much more simplified than
those at present in use and in spite of the said connection being much lighter the
capacity is much greater than the connection at present known. A saddle rod a runs
through this tubular connection and consists of a tube, on the upper end of which a
sleeve is arranged and the tube connected to the sleeve by means of the screw t which
runs through the ring u Fig. 5.
A flat plate k is soldered onto the rear side of the saddle rod a and serves in
combination with the slotted sleeve b as guide for the saddle rod a. The slotted
sleeve b in connection with the flat plate k serve to prevent all lateral movement of
the saddle rod a.
A short axle protrudes from the extension of the front wheel fork d; on this
extension of the front wheel I arrange a sleeve or muff i through which the handle
bar is inserted.
g
On the short axle protruding from the steering rod I fix the spring whilst the peg
or pin h protruding through the sleeve of the handle bar 9 rests on the upper
part of the said spring; the pin or peg h moves in a guide slot o in the sleeve i
Figs. 2ª 2b 2c.
The spring to take the vibrations or concussions from the front wheel so that the
same are not felt by the hand resting on the handle bar, which is evident from Fig. 2ª
as the spring will only be more or less compressed according to the force of
the concussion, so that the hand will only feel the slight oscillations of the
handle bar.
Besides the two springs arranged under the saddle, two further springs e are
employed, Fig. 1, the upper ends of which are inserted in the two borings or
orifices wow of the flanges to the ring u, attached to the saddle rod by the bolt
or screw t, Fig. 5, whilst the lower ends of the said springs are held in two sleeves or
rings n on a suitable axle by means of the screws q. A flat piece of iron m is welded
to the axle connecting the two springs n, and is provided with a longitudinal slot to
receive the screw by means of which the piece of iron m is attached between the
frame, the fork d and the connection c.

page_text: The object of this piece of iron.m is to transfer the pressure of the springs e to the
fork of the rear wheel by means of the connecting piece between the rings n holding
the said connecting-piece.in proper position.
In order that the saddle can be adjusted to the front or rear, a sleeve x for receiving
the upper saddle springs. is arranged on the saddle rod and is fixed in position by
means of a screw z. Instead of the leaf-spring helical springs can be employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to he performed, I declare that what I
claim is :-
A spring frame velocipede, in which the saddle rod a arranged in a slotted sleeve b
is led through the main connecting piece c of the frame, the vibrations and concussions
are taken up by means of symmetrically arranged springs e, the main connecting
piece c is for safety sake strengthened, and the concussions transmitted to the hands
are decreased by being able to partially rotate, the handle bar g which rests with the
pin on the spring for on one, two or more helical springs, substantially as..set
forth and shown.
