Improvements in or relating to the Adjustment of the Saddle or
Seat in Bicycles and similar Vehicles.
I, GOTTFRIED URSINUS, Locksmith, of Weissenfels in the Kingdom of Prussia, do
hereby declare the nature of this invention, to be as follows:-
This invention consists in the method of mounting the saddle of a bicycle or other
similar vehicle, so that it may be, at will, shifted forward or backward by the rider
without dismounting.
The saddle is caused to slide freely along the spring, for which purpose it may be
provided with friction pulleys arranged above and below the spring and grasping the
latter with a spring or otherwise regulated pressure. Means of any kind may be
provided for temporarily securing the saddle in the desired place, but I prefer to fix to
the saddle a forwardly projecting arm guided near the handle, said arm being provided
with recesses in which a pawl or catch may be introduced by means of a lever or other
device arranged within reach of the rider. On releasing the pawl, the rider can by a
motion of his body, shift the saddle forward or backward, allowing the pawl to return
to its place (under the action of a spring or otherwise) and so secure the saddle
in place.

Improvements in or relating to the Adjustment of the Saddle or
Seat in Bicycles and similar Vehicles.
I, GOTTFRIED URSINUS, Locksmith, of Weissenfels, in the Kingdom of Prussia, 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:-
This invention consists in a method of mounting or attaching the saddle of a bicycle
or other similar vehicle, so that it may be, at will, shifted forward or backward by the
rider without dismounting.
The saddle is caused to slide freely along the spring, for which purpose it may be
provided with friction pulleys arranged above and below the spring and grasping the
latter with pressure capable of being regulated. Means of any kind may be provided
for temporarily securing the saddle in the desired place, but I prefer to fix to the saddle
a forwardly projecting arm guided near the handle, said arin being provided with
recesses in which a pawl or catch may be introduced by means of a lever or other
device arranged within reach of the rider. On releasing the pawl, the rider can by a
motion of his body shift the saddle forward or backward, allowing the pawl to return
to its place (under the action of a spring or otherwise) and so secure the saddle
in place.
Referring to the accompanying drawings
Fig. 1 is a view of a part of a bicycle provided with this device, the bar being
shown released.
Fig. 2 is a similar view on a larger scale showing the bar secured, the saddle being
in its rearward position.
Fig. 3 is a plan of Fig. 2.
Fig. 4 is an enlarged view of part of Fig. 1.
Fig. 5 is a cross section on line R R Fig. 2.
The saddle S is provided with a slide G having two side rails A, the rollers B and D
and the spring E.
The saddle spring F passes between the rollers B and D. The spring E causing the
said rollers to exercise a certain pressure thereon in order to prevent shaking or
jarring of the saddle in the spring F. To the front of the slide or carriage G is
attached the arm K having the slot d therein, said slot is provided on its upper edge
with recesses fe is a pin engaging into said slot d and serving also as pivot for the
lever H. a is a nose in said lever engaging into the slot d for lifting the arm K when
operated by depression of the lever H. b is a spring tending to depress said nose, and
therefore the arm K. By depressing the lever H, the arm K is lifted and the pin e
brought into the slot d. By shifting the body it is now possible to shift the saddle to
and fro on the spring F.
On releasing the lever H the spring b tends to press down the arm K, this being

page_text: performed when the pivot e arrives under a recess of in the arm, the pin thereby
engaging in the respective recess, so as to prevent further movement of the arm K and
of the saddle.
Any other suitable mechanism may be employed in place of the lever K for releasing
the saddle.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :
In velocipedes :
1. A saddle or seat capable of movement to the front or rear during riding in
combination with means for securing such saddle in position.
2. The combination with a spring or bar of a carriage supporting the saddle or seat
and capable of movement along said spring or bar, a rod connected to said carriage,
and a pin stationary with regard to said spring or bar and capable of engaging in
recesses in the aforesaid rod for the purpose set forth.
3. The combination with a spring or bar of a carriage, supporting the saddle or seat
and capable of movement along said spring or bar, a rod connected to said carriage,
and a pin stationary with regard to said spring or bar and capable of engaging in
recesses in the aforesaid rod, of a lever engaging with said rod and capable of being
operated to release said rod from the pin aforesaid, and a spring tending to engage
said rod with the pin aforesaid.
4. A saddle or seat mounted on a carriage capable of movement along a spring or
bar said carriage having two rollers in contact with one side of said spring
or bar and one roller in contact with the other side of said spring or bar, and having
a spring or springs operating to press the said rollers upon the spring or bar for the
purpose set forth.
