IMPROVEMENTS IN THE MANUFACTURE OF BEATERS FOR THRASHING MACHINES
Year: 1865

page_text: LETTERS PATENT to William Gray, Edward Gray, and John Gray,
carrying on Business under the Style or Firm of Charles Gray and Sons,
of Saint Philip's Works, Sheffield, in the County of York, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF BEATERS FOR
THRASHING MACHINES."
Sealed the 23rd January 1866, and dated the 21st November 1865.
PROVISIONAL SPECIFICATION left by the said William Gray, Edward
Gray, and John Gray at the Office of the Commissioners of Patents,
with their Petition, on the 21st November 1865.
We, WILLIAM GRAY, EDWARD GRAY, and JOHN GRAY, carrying on Business
under the Style or Firm of Charles Gray and Sons, of Saint Philip's Works,
Sheffield, in the County of York, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF BEATERS FOR THRASHING
MACHINES," to be as follows:-
The revolving beater or drum in ordinary thrashing machines consists of
several longitudinal bars firmly secured and attached to arms or spokes, or to
the periphery of wheels affixed to a central shaft or axis with which the beater
or drum revolves.
This Invention consists, firstly and principally of the rolling of steel of any
description or wrought iron similar to the shape or design shewn on Drawing,
Figs. 1, 2, and 3, and the application of such rolled steel or wrought iron to
be used or applied as beaters for thrashing machines. We do not confine
ourselves to the precise shape shewn on the Drawing, as the same may be

page_text: altered or modified as circumstances may require. These beaters made of
rolled steel or wrought iron are superior and more durable than those now
generally used.
Secondly, this Invention consists of fluting or grooving in steel or wrought
iron the surfaces of the bars of the beater transversely in the manner shewn
on Drawing, Fig. 1. Fig. 2 shews an end section, full size, and Fig. 3 a
section full size in perspective, by which the shape or design is clearly shewn.
The part hollowed out underneath the casting in Fig. 2 is for the purpose of
reducing the weight.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Gray, Edward Gray, and John Gray in the Great
Seal Patent Office on the 17th March 1866.

page_text: NOW KNOW YE, that I, the said William Gray, on behalf of myself
and the said Edward Gray and John Gray, do hereby declare the nature of
the said Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement and
accompanying Drawings:-
The revolving beater or drum in ordinary thrashing machines consists of
several longitudinal bars firmly secured and attached to arms or spokes, or
to the periphery of wheels affixed to a central shaft or axis with which the
beater or drum revolves.
This Invention consists, firstly and principally in the rolling of steel or
wrought iron of any description similar to the shape or design shewn on
Drawing, Figs. 1, 2, and 3, and the application of such rolled steel or
wrought iron to be used in the manufacture of beaters for thrashing machines.
I do not confine myself to the precise shape shewn in the Drawing, as the
same can be altered or modified as circumstances may require. These beaters
being made of rolled steel or wrought iron are superior and more durable than
those now generally used.
Secondly, this Invention consists of fluting or grooving the surface of the
bars of the beaters, such grooves being made transversely as shewn in the
Drawing, Fig. 1. Fig. 2 shews end section, full size, and Fig. 3 a section of
beads, full size in perspective, by which the shape or design is clearly shewn.
The parts hollowed out underneath the surface being for the purpose of
reducing the weight.
Having thus described the nature of our Invention, and the manner in
which the same is or may be performed, we declare that what we claim and
desire to be secured by the herein-before in part recited Letters Patent is, the
improvements in the manufacture of beaters for thrashing machines, sub-
stantially as herein-before described and illustrated in the Drawings, or any
mere modification or imitation thereof.
In witness whereof, I, the said William Gray, on behalf of myself and
the said Edward Gray and John Gray, have hereunto set my hand
and seal, this Fifteenth day of March, in the year of our Lord One
thousand eight hundred and sixty-six.
WILLIAM GRAY. (L.S.)
