Year: 1873

page_text: LETTERS PATENT to Isaac Bramham Coldwell, of Barnsley, in the
County of York, for the Invention of "IMPROVED MEANS OF OBTAINING
MOTIVE POWER."
Scaled the 16th January 1874, and dated the 26th November 1873.
PROVISIONAL SPECIFICATION left by the said Isaac Bramham
Coldwell at the Office of the Commissioners of Patents, with his
Petition, on the 26th November 1873.
I, ISAAC BRAMHAM COLDWELL, of Barnsley, in the County of York,
do hereby declare the nature of the said Invention for "IMPROVED MEANS
OF OBTAINING MOTIVE POWER," to be as follows:-
:-
My Invention relates to improved means for obtaining motive power
for driving machinery of any kind, or for any other purpose desired.
My Invention consists in the employment of a drum mounted on
a horizontal shaft on which a fly wheel is also carried, which drum
is revolved in a continuous manner by the power of weighted levers
applied through the medium of a roller revolving in contact with

page_text: -
the circumference of the drum, and bearing thereon with a pressure
due to the gravity of the weighted levers at a point situated at a
suitable distance from the vertical plane of the drum axis. The roller
is mounted in sliding bearings fitted in guides in vertical uprights
placed one at either side of the drum, so that the roller shall always
be maintained in contact therewith. The roller axis is connected at
cach end by a suitable connecting rod or link with a lever pivoted
at one end to a suitable standard, and loaded at the other with a
movable weight, which may be adjusted in any required position along
the lever, according to the power required. The gravity of the weighted
levers thus causes the roller to bear on the drum with a force dependent
on the extent to which the levers are loaded, in such manner that
motion will be imparted to the drum, and the power thus obtained
may be applied to compress air for working engines by means of suitable
pumps driven from the drum shaft, or the motion may be applied in
other manner by means of any suitable arrangement of gearing.
any
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Isaac Bramham Coldwell in the Great Seal Patent
Office on the 27th February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ISAACS
BRAMHAM COLDWELL, of Barnsley, in the County of York, send
greeting.
