Improvements in Velocipedes.
I JOHANN MATHIAS GOLDERER of Straubing in the Kingdom of Bavaria
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to velocipedes and principally to tricycles; and the object
of the improvements is to cause the weight of the riders body as exercised in an
up and down movement to propel the velocipede. To this end the seat is pivoted
in the frame so that it may be rocked upon its pivots by an up and down move-
ment on the part of the rider. To the seat are connected bell crank levers to
which are attached rods controlling ratchet pawls which engage with ratchet
wheels on the axles of the driving wheels so that both the downward and the
upward movement of the seat causes the ratchet wheels to be revolved and thus
propel the vehicle. To these rods aforesaid may be suitably, directly or indirectly,
attached, other rods which may assist the propulsion by thrusting against the
ground. When not required these latter rods may be hooked up out of action.
The invention further relates to the position of the velocipede when ascending
or descending hills, and consists in means for enabling the velocipede to be
adjusted to remain horizontal when moving on a slanting surface. The steering
wheel is carried in a frame having a vertical king bolt extending through a
socket in the frame of the velocipede. A chain is attached to the head of the
king bolt and extends over a pulley on the velocipede frame near the king bolt,
and is carried within reach of the rider where it is provided with a fastening. By
this means the velocipede frame can be raised or lowered on the king bolt and so
be kept horizontal while the velocipede is travelling on an incline.

Improvements in Velocipedes.
I JOHANN MATHIAS GOLDERER of Straubing in the Kingdom of Bavaria
Gentleman 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:―
This invention relates to velocipedes and principally to tricycles: and the object
of the improvements is to cause the weight of the rider's body as exercised in an
up and down movement to propel the velocipede. To this end the seat is pivoted
in the frame so that it may be rocked upon its pivots by an up and down move-
ment on the part of the rider. To the seat are connected bell crank levers to
which are attached rods controlling ratchet pawls which engage with ratchet
wheels on the axles of the driving wheels so that both the downward and upward
movement of the seat causes the ratchet wheels to be revolved and thus propel the
vehicle.

To these rods aforesaid may be suitably directly or indirectly attached, other
rods which may assist the propulsion by thrusting against the ground. When not
required, these latter rods may be hooked up out of action.
The invention further relates, to the position of the velocipede when ascending
or descending hills and consists in means for enabling the velocipede to be adjusted
to remain horizontal'when moving on a slanting surface. The steering wheel is

page_text: carried in a frame having a vertical king bolt extending through a socket in the
frame of the velocipede. A chain is attached to the head of the king bolt and
extends over a pulley on the velocipede frame near the king bolt and is carried
within reach of the rider where it is provided with a fastening. By this means
the velocipede frame can be raised or lowered on the king bolt and so be kept
horizontal while the velocipede is travelling on an incline.
In the accompanying drawings Fig. 1 is an elevation. Fig. 2 a plan and Figs. 3
to 6 are detail views of the improved velocipede..
The velocipede frame a with the parcel carrier m rests partly upon the axle b
of the two front wheels and partly upon the hind wheel. The seat e resting behind
on the supporting spring d is arranged in front to swing on the shaft e and is
connected by rods with one of the arms of the three-armed levers / h¹ pivoted on
the frame at each side at g other arms of said levers being connected also by
the rods T T and T T to lugs or arms on the discs or boxes i i¹, located
loosely upon the main axle bas may be understood from the example shown in
Figs. 3 to 6. Each of these discs contains a pawl which gears into a toothed
wheel securely keyed upon the axle as may be seen in Figs. 3 and 4.
sequently there are four ratchet wheels k on the main axle, corresponding
respectively each to one of the rods T T T T'. If by a suitable up, and down
motion of the body, the seat is pushed down in backward direction the rods frock
the angle levers h and h' whereby the discs are operated by means of the
rods T T T T as shown in Figs. 2 and 3 and the discs and move forward (in
the direction of the arrow) the pawl / touching with its rear lever arm the pin n',
will operate the ratchet wheel k and consequently propel the two front wheels.
Con-
The forward motion of the rode T¹ and T' of the discs i and causes a return
of the rods T and T³ consequently a rotation of the discs and in opposite
direction to the arrow, when as seen by Fig. 3 their pawls, pass idly over the
teeth of the respective ratchet wheels. On raising the body the spring d operates
to lift the seat and move the levers h and h in the opposite directions as above.
In this manner by an up and down motion of the body when the rider supports
himself on the side rails, the propelling of the vehicle can be caused by the raising
and lowering of the seat.
To provide for the steering of the vehicle two rods z z¹ guided in eyes n
arranged on the parcel carrier m are connected by chains on the one hand with
the levers t and t¹ loosely supported on the axle 6 and on the other hand with the
yoke o fastened to the neck of the hind wheel forks. The steering is effected by
moving the levers t t¹ by hand.
The hind wheel can be raised or lowered during riding by means of the chain k¹
which is fastened to the lever y having a suitable check action and loosely
supported on the axle b and at the other end to the king bolt or neck of the hind
wheel fork. When the chain is pulled, that is when the lever y is pulled back the
bolt is pulled downwards. The hind wheel therefore takes up a lower position.
In the opposite case when the lever y is pushed forward, the chain will be loosened,
and the frame, under the weight of the rider, sinks until the chain k¹ is tensioned.
The position of the hind wheel depends therefore upon the position of the lever y.
The rods such as F F are fastened one to each of the discs iii for assisting
in the propulsion, these rods when suitably guided push against the ground and thus
give considerable assistance: when not used they are suspended on or by chains.
Also the steering levers and that for adjusting the hind wheel can be arranged
instead of on the main axle on either or both sides of the frame of the vehicle in
order that the friction may be lessened. By means of the segment rail g,with
adjusting thumb screw the step or foot rest which may be folded at p can be
adjusted to different positions.
The position of the pawl, shown in dotted lines, in Fig. 3 causes backward driving
in the opposite manner to the forward driving. The displacement of the pawl 7 is
caused by the levers H pivoted at the axis of said pawl which levers are brought
from the position shown in Fig. 3 into that shown in dotted lines and by means of

page_text: their pin n' cause a rotation of the pawl into the position shown in dotted lines;
the levers H are held in the one or other position by the springs u on the discs i.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A velocipcde in which the up and down motion of the body of the rider is
transferred by a vibrating seat to bars T carrying pawls engaging with toothed
wheels on the driving axle whereby the driving wheels are moved substantially as
described.
2. A velocipede in which the rotary movement communicated to the driving
axle by means of pawls and toothed wheels k may be reversed by reversing said
pawls by means of lever H substantially as set forth.
3. A velocipede in which the forks of the steering wheel are provided with a
neck of extended length sliding in the frame and controlled by a chain and lever
or equivalent adjusting device substantially as set forth for the purpose of the
adjustment of the frame to a level position when either on level or inclined ground.
