Device for Driving Sledges.
Year: 1893

page_text: Date of Application, 6th Nov., 1893
Complete Specification Left, 4th Aug., 1894-Accepted, 15th Sept., 1894
I, JOSEPH SCHOLZ of 11, Laubenstrasse, Leobschütz, Germany, Gentleman do
hereby declare the nature of this invention to be as follows:-
The present invention relates to a device for driving sledges, enabling the rider
to propel the sledge by treading.
On the runners of the sledge a four-legged frame is fixed of which the casing
holds a spindle, which carries, by means of a fork, the driving-wheel the rim of
which is provided with projecting points. The driving-wheel is worked by pedals
arranged before the seat." The pedals are pushed loosely on the axle and
connected with the cranks by the connecting-rods. The cranks are, by means of
the axle, borne in an eye of the spindle and transfer, with the aid of a chain-gear,
the movement on the driving-wheel of which the projecting points or thorns are
catching into the ice and propel the sledge.
A spring, which at the one end is supported against the casing and at the other
end against a projection of the spindle, always presses the driving-wheel against
the ice and renders the same elastic when meeting with elevations of the ice etc.
By means of a handle the spindle can be oscillated together with driving-wheel,
thus steering the sledge to any direction required.
Dated this 4th day of November 1893.
COMPLETE SPECIFICATION.
Device for Driving Sledges.
I, JOSEPH SCHOLZ of 11 Laubenstrasse, Leobschütz, Germany, 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:-
The present invention relates to a device for driving sledges, enabling the rider
to propel the sledge by treading.
Fig. 1 of the accompanying drawing is a side-view of a sledge provided with
this driving-device,
Fig. 2 is a section of the same.
On the runners a of the sledge the four-legged frame is fixed of which the
casing c holds the spindle d which carries, by means of the fork c¹, the driving-
wheel A the rim of which is provided with projecting points. The driving-wheel
is worked by pedals g arranged before the seat B. The pedals g are pushed
loosely on the axle g' and connected with the cranks n by the connecting-rods h.
The cranks n are, by means of the axle o, borne in an eye of the spindle d and
transfer, with the aid of the chain-gear i k l, the movement on the driving-wheel A
of which the projecting points or thorns m are catching into the ice and propel the
sledge.
A springs, which at the one end is supported against the casing c and at the
other end against a projection s' of the spindle d, always presses the driving-wheel
against the ice and renders the same elastic when meeting with elevations of the
ice etcetera.

page_text: By means of the handle e the spindle d can be oscillated together with driving-
wheel A, thus steering the sledge to any direction required.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :
In a sledge the driving device, consisting of the driving-wheel A, the fork c',
the pedals g, the connecting-rods h, the cranks n and the chain gear i kl, as set
forth.
JOSEPH SCHOLZ.
