PROVISIONAL SPECIFICATION left by the said Lorentz Albert Groth at
the Office of the Commissioners of Patents on the 14th March 1881.
LORENTZ ALBERT GROTH, K.G.V., Civil Engineer, and Proprieter of the
Scandinavian Patent Office, under the Firm of L. A. Groth & Co., 97, Finsbury
Pavement, London, and 20, Forhaabningsholms Allee, Copenhagen. "AN IMPROVED
APPARATUS FOR. GIVING MOTION TO CARRIAGES, VESSELS, MACHINES, AND OTHER
MOVING BODIES." A communication from abroad by Gustaf Liedman, Gentleman,
and Carl Beger, Mechanician, both of Berlin, in the German Empire.
The Invention relates to carriages and other moving bodies, the continuous
movement of which is effected by one or several persons seated thereon by the
action of a rocking seat upon the driving apparatus.
The body of the carriage carries a rocking seat, the swinging movement of which
is facilitated by a hand lever. The rocking seat is connected with the axle of the
carriage by means of a system of springs and pawls.
The steering or guiding is effected by a lever in the usual way.
On the axle is placed the spring and pawl mechanism, which consists of two
bosses keyed on the axle, two discs turning loosely thereon but held sidewise by
collars. The bosses are fitted with pawls so arranged and adapted that when the
discs are turned in one direction the axle turns with them, but when the said discs
are turned in the opposite direction they have no effect on the axle.
.

page_text: On the bosses of the discs grooves are turned, over which pass cords, bands, or
chains, one end of each of which is fixed in the said grooves, the other ends being
connected to the rocking seat.
One set of cords, bands, or chains, by each alternate swing of the rocking seat
turns the discs and the axle forwards and moves the carriage; the other set of cords, 5
bands, or chains being made of elastic material, such as indiarubber, or provided
with spiral springs, draws back each disc when the corresponding actuating chain
is not operating upon it and places it ready for another operation.
This principle and apparatus are also applicable to railways, velocipedes, boats,
vessels, and machinery of all kinds, when the aforesaid spring and pawl mechanism 1
is applied to a suitable shaft, and by the employment of a suitable arrangement of
gearing the carriage or other body may be moved forwards or backwards, and in
some cases the wheels may be furnished with paddles or floats.

by the said Lorentz Albert Groth in the Great Seal Patent Office on the
9th July 1881.
LORENTZ ALBERT GROTH, K.G.V., Civil Engineer, and Proprietor of the
Scandinavian Patent Office, under the Firm of L. A. Groth & Co., 97, Finsbury
Pavement, London, and 20, Forhaabningsholms Allee, Copenhagen. "AN IMPROVED
APPARATUS FOR GIVING MOTION TO CARRIAGES, VESSELS, MACHINES, AND OTHER
MOVING BODIES." A communication from abroad by Gustaf Liedman, Gentleman,
and Carl Beger, Mechanician, both of Berlin, in the German Empire.
The Invention relates to carriages and other moving bodies, the continuous
movement of which is effected by one or several persons seated thereon by the
action of a rocking seat upon the driving apparatus.
In Figures 1 and 2 of the Drawings, A is the body of the carriage; B, the
rocking seat, the swinging movement of which is facilitated by a hand lever d.
The body A of the carriage is connected with the axle c by means of a system of
springs 8, 8; x, x, are the fulcra of the rocking seat B.
The steering or guiding is effected by a lever e in the usual way.
On the axle c is placed the spring and pawl mechanism f, shown to an enlarged
scale and more in detail in Figures 3 and 4, in which g, g, are two bosses keyed on
the axle c; h, h, are two discs turning loosely on the said axle but held sidewise
by collars q, q. The bosses g, g, are fitted with pawls i, i, so arranged and adapted
that when the discs h, h, are turned in the direction of the arrow, Fig. 3, the
axle c turns with them; but when the said discs h, h, are turned in the opposite
directions they have no effect on the axle.
On the bosses of the discs h, h, grooves k, k, are turned, over which pass cords,
bands, or chains 1, 1, and m, m, one end of each of which is fixed in the said
grooves, the other ends being connected at o, o, to the rocking seat B.
One set of cords, bands, or chains 4, 7, by each alternate swing of the rocking
seat B turns the discs h, h, and the axle c forwards and moves the carriage; the
other set of cords, bands, or chains m, m, being made of elastic material, such as
india rubber, or provided with spiral springs, draws back each disc h in the
direction opposite to that indicated by the arrow when the corresponding actuating
chain is not operating upon it, and places it ready for another operation.
This principle and apparatus are also applicable to railways, velocipedes, boats,
vessels, and other machinery of all kinds, when the aforesaid sping and pawl
mechanism, shown in Figures f1 and 2, and to larger scale in Figs. 3 and 4, is
applied to a suitable shaft, and by the employment of a suitable arrangement of
gearing the carriage or other body may be moved forwards or backwards, and in
some cases the wheels may be furnished with paddles or floats.
Having now described the nature of the said Invention, and the manner in
which the same is to be carried into effect, I would have it understood that what
I claim is,
The apparatus for the transmission of motion to carriages, boats, vessels, and
machinery from a rocking seat B and lever d to the wheel axle c, consisting
essentially of the bosses g, g, discs h, h, pawls i, i, and the cords, bands, or chains
l, l, and m, m, arranged, combined, applied, and operating as hereinbefore described
and illustrated in the Drawings.
In witness whereof, I, the said Lorentz Albert Groth, have hereunto set my
hand and seal, this Twenty ninth day of June, in the year of our Lord
One thousand eight hundred and eighty one.
