IMPROVEMENTS IN SHEEP SHEARS
Year: 1874

page_text: LETTERS PATENT to George Haseltine, of the "International Patent
Office," Southampton Buildings, London, Doctor of Laws, for the
Invention of "IMPROVEMENTS IN SHEEP SHEARS."-A communication
from abroad by David Brown, of Glencoe, South Australia, Sheep
Declaration, on the 26th March 1874, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office,"
Buildings, London, Doctor of Laws, send greeting.
Southampton
WHEREAS I am in possession of an Invention for "IMPROVEMENTS

page_text: crosswise, so that it assumes the form of a slot across the blade: By
loosening the screw in this slot the blade can be adjusted with the
greatest nicety, working on the other screw like a pivot, and when it is,
adjusted can be kept so by making the slot screw. tight again. Of course
the mechanical arrangement might be reversed and the slot be made in
the arm instead of in the blade if. so. preferred. Instead of the slot two
or more holes might be made in the same line, but in that case the
points could not be adjusted with the same nicety as with the slot.

loosening the screw in this slot the blade can be adjusted with the:
greatest nicety, working on the other screw like a pivot, and when it is,
adjusted can be kept so by making the slot screw tight again. Of course
the mechanical arrangement might be reversed and the slot be made in
the arm instead of in the blade if. so. preferred. Instead of the slot two
or more holes might be made in the same line, but in that case the
points could not be adjusted with the same nicety as with the slot.
It is necessary that the blade should be of an equal thickness: where!
the slots or substituted holes are made.
Rivets can be substituted for the screws if so desired, but I prefer to
use steel screws with a deep thread. The arm might be made to project
from the blades instead of from the handle.
In order however that the said Invention may be distinctly understood
I have illustrated the same in the accompanying Drawing. A is the
handle of the shears; B, B, are the projecting arms thereon; and B¹, B³,
the holes therein; C, C, are blades; D, D, are the slot holes; and
E, E, the round holes therein. By placing the blades in position on the
projecting arms the slot holes D will be found in opposition to the round
holes B', and the round holes E in opposition to the round holes B².
The holes in the blades must be countersunk to receive the heads of the
screws, so that they present no obstruction to the free working of the
sliears. By this method of construction the blades may have any
"set"
given to them by placing them in a vice.
Having thus fully described the said Invention as communicated to
me by my foreign correspondents, and the manner of performing the
same, I would have it understood that I do not confine myself to the
precise details herein set forth and explained so long as the nature of the
said Invention be retained, but I claim,-
First. Making sheep shears with the blades separate from the handle
and connected to the same by screws or rivets, substantially as herein
described.

page_text: Third. Making a slot or a series of holes in the blade C or the arm B
for adjusting the points of sheep shears, substantially as herein
described.
In witness whereof, I, the said George Haseltine, have hereunto
set my hand and seal, this Twenty-sixth day of March, in the 5
year of our Lord One thousand eight hundred and seventy-
four.
Witness,
JAMES EDWARDS,
8, Southampton Buildings,
London.
GEORGE HASELTINE. (L.S.)
