I WALTER ALPHEUS ROLLINS of Wyattville, Central Hill, Upper Norwood in
the County of Surrey, Secretary to a public Company do hereby declare the
nature of said Invention for A NEW OR IMPROVED CONSTRUCTION OR ARRANGEMENT
OF GEARING OR APPARATUS FOR TRANSMITTING MOTION FROM ONE PART THEREOF
TO ANOTHER IN ONE DIRECTION ONLY AND FOR PERMITTING ONE OR OTHER OF
SUCH PARTS TO REVOLVE INDEPENDENTLY OF OR IN CONTRARY DIRECTION TO THE
OTHER, to be as follows: -
My Invention is applicable to mowing machines to tricycles and to other
machinery and apparatus where it is required to transmit motion from one part
thereof to another in one direction only and to permit one or other of such parts
to revolve independently of or in contrary direction to the other.
I will first describe my invention as applied to a mowing machine. The driving
or running wheels of the machine are each fixed to a separate shaft, the inner ends
of these shafts are formed with enlargements which fit and are capable of revolving
independently of each other within elongated bosses fitted to a wheel occupying a
position between such shafts. These elongated bosses are so bored or shaped
internally as to receive two blocks which are capable of sliding endwise therein but
are compelled to revolve therewith.
These blocks are formed each on its outer face with ratchet teeth to fit similar
teeth formed on the inner ends of the shafts of the driving or running wheels and
a spring is placed between the sliding blocks to force the latter outwards and keep
thein in gear with the shafts when the machine is running in a straight line
forwards, but in the event of the machine being backed or turned the driving or
running wheels or one of them can revolve independently of the sliding blocks
which as the ratchet teeth pass each other will be slidden backwards within their
containing bosses.
The wheel between the two shafts of the running or driving wheels is formed on
its periphery with teeth by which rotary motion may be given to the working

page_text: parts of the machine by any convenient arrangement of gearing. The elongated
bosses of the central wheel are so fitted and connected to the contained shafts as
to form a firm connection between them and yet permit of their independent
revolution.
In applying my invention to a tricycle a similar arrangement of parts to that
above described is employed but instead of the running wheels being caused to
give rotary motion to the central wheel, the latter is rotated to give motion to the
running wheels and is so formed as to receive rotary motion from the crank shaft
by means of a chain or band passing around the same and around a wheel on the
crank shaft or in other convenient manner.
If desired only one of the running wheels may be driven as above described the
other being allowed to run loosely, in this case one of the sliding blocks and the
ratchet teeth on the end of the shaft of one of the running wheels would be
dispensed with.
My improved arrangement of gearing or apparatus is simple, cheap and effective
whilst it is completely protected from dust and dirt.

the County of Surrey, Secretary to a public Company do hereby declare the
nature of my Invention for A NEW OR IMPROVED CONSTRUCTION OR ARRANGEMENT
OF GEARING OR APPARATUS FOR TRANSMITTING MOTION FROM ONE PART THEREOF
TO ANOTHER IN ONE DIRECTION ONLY AND FOR PERMITTING ONE OR OTHER OF
SUCH PARTS TO REVOLVE INDEPENDENTLY OF OR IN CONTRARY DIRECTION TO THE
OTHER, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention is applicable to mowing machines, to tricycles and to other
machinery and apparatus where it is required to transmit motion from one part
thereof to another in one direction only and to permit one or other of such parts to
revolve independently of or in contrary direction to the other.
I will first describe my Invention as applied to a mowing machine. The driving
or running wheels of the machine are each fixed to a separate shaft, the inner ends
of these shafts are formed with enlargements which fit and are capable of revolving
independently of each other within elongated bosses fixed to a wheel occupying a
position between such shafts. These elongated bosses are so bored or shaped
internally as to receive two blocks which are capable of sliding endwise therein but
are compelled to revolve therewith.
These blocks are formed each on its outer face with ratchet teeth to fit similar
teeth formed on the inner ends of the shafts of the driving or running wheels and
a spring is placed between the sliding blocks to force the latter outwards and keep
them in gear with the shafts when the machine is running in a straight line
forwards, but in the event of the machine being backed or turned the driving or
running wheels or one of them can revolve independently of the sliding blocks
which as the ratchet teeth pass each other will be slidden backwards within their
containing bosses.
The wheel between the two shafts of the running or driving wheels is formed on
its periphery with teeth by which rotary motion may be given to the working
parts of the machine by any convenient arrangement of gearing. The elongated
bosses of the central wheel are so fitted and connected to the contained shafts as
to form a firm connection between them and yet permit of their independent
revolution.
My improved arrangement of gearing or apparatus is simple, cheap and effective
whilst it is completely protected from dust and dirt.
And in order that the said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1. is a plan view of a mowing machine provided with my improvement.
Figure 2 is a cross-sectional elevation on the line x, x Figure 1.
Figure 2 shows another form of cross section of parts on the line xx, of
Figure 1 which may be employed in lieu of that shown at Figure 2. Figure 3 is
a cross-sectional elevation of the same on the line y y, Figure 1.
I have shown my invention as applied on a mowing-machine, but it can also be
applied on other machines.

page_text: The independent shafts A are each provided on the inner end with an enlarge-
ment, B, on the end surface of which ratchet-teeth a are formed. The enlargements
project into the tubular ends of squared or circular hollow bosses C, projecting
from the opposite sides of a wheel D, held between the inner ends of the shafts in
each of which bosses a block, E, is held in such a manner that it can slide in the
boss in the direction of the length of the same, but must turn with the boss.
Ratchet-teeth b are formed on the outer end of each block E, and a spiral spring, F,
is interposed between the inner end of each block E and the outer surface of the
wheel, which springs press the toothed ends of the blocks E against the toothed
ends of the enlargements B, thus keeping the blocks engaged with the enlargements.
If the machine is moved in the direction of the arrow a¹, the shafts turn the
wheel D; but if the machine is moved in the inverse direction of the arrow a¹,
the teeth of the enlargements will slide over the teeth on the sliding blocks E, and
the wheel D will not be revolved. The wheel D is provided with teeth or other
means for transmitting motion to other parts of machinery.
Shafts can be coupled in a manner similar to the one described herein.
In applying my invention to a tricycle a similar arrangement of parts to that
above described is employed but instead of the running wheels being caused to give
rotary motion to the central wheel, the latter is rotated to give motion to the
running wheels and it is so formed as to receive rotary motion from the crank
shaft by means of a chain or band passing around the same and around a wheel
on the crank shaft or in other convenient manner as will be readily understood.
If desired only one of the running wheels may be driven as above described the
other being allowed to run loosely, in this case one of the sliding blocks and the
ratchet teeth on the end of the shaft of one of the running wheels would be
dispensed with.
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
1. In a device for transmitting motion, the combination, with a shaft having
ratchet teeth on its end, of a tubular boss, into which the end of the shaft projects
on the other part of the machinery and a spring-pressed block in said tubular boss,
having ratchet-teeth engaging those of the shaft, substantially as herein shown and
described.
2. In a device for transmitting motion, the combination, with the shaft A,
provided with the enlargement B, having ratchet-teeth a, of the wheel D, provided
with the hollow boss C, the sliding block E, provided with ratchet-teeth b and the
spring F, substantially as herein shown and described.
