Year: 1882

page_text: LETTERS PATENT to Leon L'Hollier and George Asher, both of Birmingham, in
the County of Warwick for an Invention of " NEW OR IMPROVED APPLIANCES
FOR OBTAINING MOTIVE POWER"
PROVISIONAL SPECIFICATION left by the said Leon L'Hollier & George
Asher at the Office of the Commissioners of Patents on the 20th November
1882.
LEON. L'HOLLIER, and GEORGE ASHER, both of Birmingham, in the County of
Warwick, "NEW OR IMPROVED APPLIANCES FOR OBTAINING MOTIVE POWER,"
"
The object of this Invention which relates to improved apparatus for obtaining
motive power is to supersede existing arrangements of mechanism for obtaining
power by steam, gas, hot air, water, and manumotive and other usual means,
and to provide a simple means of obtaining power applicable to various useful
purposes.
One modification of the improved apparatus is illustrated on the accompanying
drawing in which it is shown as constructed with a shaft or spindle 1, which at one
part is formed with an external screw thread 2, which engages with a fixed part 3,
of the framing 4. The shaft or spindle is also guided by another part 5, of the
framing, in which part it can freely turn and move endways. Freely mounted on
the spindle is also a spherical, conical, or other suitably shaped piece 6. which is
formed with a surrounding band or worm 7, of slanting or helical grooves or teeth.
The shaft is also provided with a handle 8, by which it can be rotated one way or
the other, and with friction rollers 9, 10; between which the part 6, is placed and
which are caused to bear in one or the other direction upon the part 6, when the
spindle is turned by the handle and pressure put upon them. The inclined teeth
of the part 6, engage with the teeth of a driving wheel 11, and thus when pressure
is as above mentioned put on the part 6, it turns together with the wheel 11 in
gear therewith, and this motion is continuous so long as the said pressure is
maintained, and is communicated to the driving spindle 12, and thence by bands
or other wheels to where else required.

by the said Leon L'Hollier & George Asher in the Great Seal Patent Office
on the 16th May 1883.
LEON L'HOLLIER and GEORGE ASHER both of Birmingham in the County of
Warwick "NEW OR IMPROVED APPLIANCES FOR OBTAINING MOTIVE POWER
This Invention relates to improved apparatus for obtaining motive power-and
its object is to supersede existing arrangements of mechanism for obtaining power
by the agency of Steam, gas, hot air, water, and manumotive and other usual
means, and to provide a simple means of obtaining power applicable to various
useful purposes.
The principle of the Invention is illustrated on the accompanying drawings
which illustrates one modification of the improved apparatus.
The improved apparatus is constructed with a shaft or spindle 1, wbich is formed
with an external screw thread at 2, and at this part engages with a fixed part 3
of any suitable framing 4; At its upper end, the shaft is guided by another part 5
of the framing, and in this part it can freely turn and move endways-The shaft
is also provided with a handle 6 by which it can be rotated in both directions and
with projecting centres 7 carrying friction, rollers 8, 9, Freely mounted on the
shaft, and with a slight freedom of movement between the rollers 8. 9 is a
spherical, conical or other suitably shaped piece 10, which is formed with a
surrounding band or worm 11 of slanting or helical grooves or teeth-These teeth
engage with the teeth of a driving wheel 12 mounted on a shaft 13 supported in
bearings 14 by the framing 4 and the wheel 12 or shaft 13 can be connected by
bands or otherwise with any machinery to be actuated. The shaft 1, is set
slightly excentric to the wheel 12.
Upon the shaft 1, being turned by its handle 6, say in the direction of the
arrow 15, the rollers 8, are caused to exert downward-pressure-upon the piece 10
which is then suspended with its teeth 11 in driving contact with the teeth of
the wheel 12, and the piece 10, and wheel 12 in gear therewith then together
turn, and this motion is continuous so long as the said pressure is maintained, and
is communicated by the means herein-before indicated to where required to be
utilized-A reverse action is obtained by reversing the direction of the pressure.
Having thus particularly described and ascertained the nature and objects of our
said Invention and in what manner the same is to be or may be performed or
carried into practical effect we would observe in conclusion that what we consider to
be novel and original and therefore claim as constituting the Invention secured to
us by the herein before in part recited Letters Patent, is :-
In apparatus for obtaining motive power; the combination of means by which
pressure can be exerted, with an independently acting part, in gear with a mounted
toothed wheel or its equivalent, and which part upon having such pressure
exerted upon it, revolves together with the wheel in gear therewith and imparts
motion to any connected machinery substantially as hereinbefore described.
In Witness whereof we the said Leon L'Hollier and George Asher have
hereunto set our hands and seals this twenty third day of April in the
year of our Lord one thousand eight hundred and eighty three.
Witness,
JOHN KENDRICK,
