Year: 1872

page_text: LETTERS PATENT to Samuel Osborn, of the Olyde Steel and Iron
Works, Sheffield, in the County of York, for the Invention of "Iж-
PROVEMENTS IN MAKING FINGER BEAMS FOR REAPING AND MOWING MACHINES,
AND IN APPARATUS THEREFOR.
"
Sealed the 20th May 1873, and dated the 23rd November 1872.
PROVISIONAL SPECIFICATION left by the said Samuel Osborn at the
Office of the Commissioners of Patents, with his Petition, on the
23rd November 1872.
I, SAMUEL OSBORN, of the Clyde Steel and Iron Works, Sheffield, in
the County of York, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MAKING FINGER BEAMS FOR REAPING AND MOWING
MACHINES, AND IN APPARATUS THEREFOR,” to be as follows, that is to say:—
This Invention has for its objects to improve, simplify, and cheapen
the making of finger beams or bars for reaping and mowing machines;
and in carrying it out a parallel bar of iron or steel is first rolled in the
ordinary way, either with two square edges or with one edge square, and
a bevil or
on the other edge, and it is subsequently submitted
"swage
""

page_text: to a pair of rolls which are adapted to receive the bar between them on
edge or at right angles to their axes.
The upper roll is formed with a groove, shaped to fit a part of the
beam, which in the case of the bevilled beam has the bevilled edge on
it, and the lower roll is formed with a broader and deeper groove than
would be required for the remainder of the beam by itself, so that a
grooved bar can be passed between the rolls through this lower groove
along with the beam. This bar is formed with a groove along its upper
side to fit the bottom edge of the beam, and this groove is tapered in
depth to suit the taper or partial taper intended to be given to the beam.
In front of and behind the rolls there are tables or guides for the grooved
bar to rest on, and this bar is moved backwards and forwards between
the rolls with the originally parallel beam, and causes the desired taper
to be gradually put on the beam.
By these means a finger beam is produced which either combines
tapering on one edge with swaging, or bevilling, or a V form or partial
V form on the other edge, or is a tapered or a partly tapered bar with
both edges square.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Osborn in the Great Seal Patent Office,
on the 22nd May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
OSBORN, of the Clyde Steel and Iron Works, Sheffield, in the County of
York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of November, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Samuel Osborn, Her special licence that I,
the said Samuel Osborn, my executors, administrators, and assigns, or
such others as I, the said Samuel Osborn, my executors, administrators,
and assigns, should at any time agree with, and no others, from time`
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the

page_text: United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN MAKING FINGER BEAMS FOR
REAPING AND MOWING MACHINES, AND IN APPARATUS THEREFOR," upon the
condition (amongst others) that I, the said Samuel Osborn, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Osborn, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by
the following statement in writing, reference being had to the accom-
panying Drawings, that is to say :-
My said Invention has for its objects to improve, simplify, and cheapen
the making of finger beams or bars for reaping and mowing machines,
and in carrying it out a parallel bar of iron or steel is first rolled in the
ordinary way, either with two square edges or with one edge'square, and
a bevil or "swage" on the other edge, and it has subsequently imparted
to it the required taper by a rolling process conducted with the aid of
improved appliances.
And in order that my said Invention and the manner of performing
the same may be properly understood, I hereunto append a Sheet of
Explanatory Drawings to be herein-after referred to, and representing
my improved arrangements.
In these Drawings the same reference numerals are used to mark the
same or like parts wherever they are repeated.
Figure 1 is a side view, and Figure 2 is a corresponding front view
showing the arrangement of the rolls and parts acting therewith. The
rolls 1, 2, are adapted to receive the bar 3 that is to be formed into a
finger beam, so as to pass between them on edge or at right angles to
their axes.
The upper roll 1 is formed with a groove shaped as at 4, to fit a square
upper edge along the bar 3, or as at 5, to fit a bar 3, with one bevil
along its upper edge, or as at 6, to fit a bar with a double bevil or
inverted V form along its upper edge.

page_text: The lower roll 2 is formed with a broader and deeper groove 7 than
what would be required for the remainder of the bar 3 by itself, so that
a grooved bar 8 can be passed between the rolls through this lower
groove 7 along with the bar 3. This bar 8 is shown in end view and in
longitudinal section in Figure 3. It is formed with a groove 9 along its 5
upper side to fit the bottom edge of the bar or beam 3, and this groove
is tapered in depth to suit the taper or partial taper intended to be given
to the beam 3. In front of and behind the rolls 1, 2, there are tables or
guides 10 for the grooved bar 8 to rest and slide upon; and this grooved
bar is moved backwards and forwards between the rolls 1, 2, with the 1
originally parallel bar 3, and causes the desired taper to be gradually
put on the bar. The rolls 1, 2, may be mounted, adjusted, and driven
as in any suitable existing arrangement of rolling mill.
By the herein-before described means I produce a finger beam 3 which
either combines tapering along one edge with swaging, or bevilling, or a 1
V form or partial V form on the other edge, or is a tapered or partly
tapered bar with both edges square.
Having thus particularly described my said Invention, and the
manner of performing the same, I have to state that I do not restrict
myself to the precise details herein described or delineated, but that what 2
I believe to be novel and original, and claim as the Invention secured to
me by the herein-before in part recited Letters Patent is, the making of
finger beams for reaping and mowing machines, with the required
longitudinal taper by passing them edgeways between rolls whilst held
in bars which move with them through the rolls, and which are formed 2
with grooves of tapering depth to receive the beams, as herein-before
described.
In witness whereof, I, the said Samuel Osborn, have hereunto set
cool this Thrants first day of May in the year of
described.
In witness whereof, I, the said Samuel Osborn, have hereunto set
my hand and seal, this Twenty first day of May in the year of
our Lord One thousand eight hundred and seventy-three.
