IMPROVED APPARATUS FOR FASTENING IMMEDIATELY AND SECURELY ANY BROKEN BAR, CARRIAGE POLE, SHAFT, OAR, SCULL, MAST, OR SCAFFOLDING
Year: 1871

page_text: LETTERS PATENT to James Gurrin, of Forty-three, Highgate Road,
Middlesex, Woollen Cloth Merchant, for the Invention of "IMPROVED
APPARATUS FOR FASTENING IMMEDIATELY AND SECURELY ANY BROKEN BAR,
CARRIAGE POLE, SHAFT, OAR, SCULL, MAST, OR SCAFFOLDING."
Sealed the 16th April 1872, and dated the 18th October 1871.
PROVISIONAL SPECIFICATION left by the said James Gurrin at the
Office of the Commissioners of Patents, with his Petition, on the
18th October 1871.
I, JAMES GUBRIN, of Forty-three, Highgate Road, Middlesex, Woollen
Cloth Merchant, do hereby declare the nature of the said Invention for
"IMPROVED APPARATUS FOR FASTENING IMMEDIATELY AND SECURELY ANY BROKEN
BAR, CARRIAGE POLE, SHAFT, OAR, SCULL, MAST, OR SCAFFOLDING," to be as
follows:-
It consists of two pieces of metal modelled on the hinge and screw
bolt principle, adapted in size and shape to the object it is intended
to fasten, and is secured round any object by one or more nuts and
screw bolts.

page_text: The formation and working are thus explained:-The two pieces of
metal forming the body of the apparatus when shaped are united by
a hinge, the inner sides are roughed or spiked when the nature of the
object requires or admits of this; then on to the sides at the line where
the apparatus meets when closed bolts are rivetted exactly opposite t
to cach other, but varying in number to the required length of the
apparatus. The bolts on one side have an opening called an eye, those
on the opposite side have a bolt projecting towards this eye at a
sufficient angle and of sufficient length to pass through it. These
projecting bolts are tapped to admit of nuts being screwed on them, 1
so that when a nut is applied to each bolt that has passed through its
corresponding eye it gradually tightens the apparatus as the nut is'
screwed till the required pressure is gained.
The fastening may be also effected by split bolts rivetted perpen-
dicularly on each side. These are tapped to admit of nuts and are 1
so made and placed that when the apparatus is pressed lightly
together, these split bolts unite at the extremities only, forming at
the point one complete screw with each pair; the nuts are then applied
as before. Or, finally, one side is made with eyes and the other with
bolts, and then the fastening, is effected with nuts as before.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Gurrin in the Great Seal Patent Office on
the 18th April 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, James
GURRIN, of 43, Highgate Road, Middlesex, Woollen Cloth Merchant,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of October, in the
year of our Lord One thousand eight hundred and seventy-one,
in the thirty-fifth year of Her reign, did, for Herself, Her heirs and 8
successors, give and grant unto me, the said James Gurrin, Her
special licence that I, the said James Gurrin, my executors, adminis-
trators, and assigns, or such others as I, the said James Gurrin, my

page_text: exccutors, 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 United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVED
APPARATUS FOR FASTENING IMMEDIATELY AND SECURELY ANY BROKEN BAR,
CARRIAGE POLE, SHAFT, OAR, SCULL, MAST, OR SCAFFOLDING," upon the con-
dition (amongst others) that I, the said James Gurrin, 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 James Gurrin, 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 :-
This Invention consists of two metallic plates curved and hinged
together on one side. These plates may be of different sizes to suit the
size of the bar required to be fastened, and when curved are brought
together and made to meet on the opposite side to the hinge by means
of cross bolts and eyes. The cross bolts meet and pass through the
eyes, and when through nuts are placed on them and screwed down,
the projecting bolts which are ready tapped for the wormed nuts until
the curved metal plates meet and form a tube.
This apparatus when placed round any splintered or broken bar,
carriage pole, shaft, oar, mast, scull, scaffolding, or rod of any kind
closes round it, the bolts passing through the eyes as far as the size
of the bar will allow and sufficient for the nuts to be placed on
them. The gradual screwing up of the nuts on the cross bolts then
brings the grip tighter and tighter together, and fixes firmly the
broken or fractured article. The rivets which hold the eyes and the
cross bolts to the grip are sometimes continued through to the interior
of grip, where they form sharp pointed studs which assist in holding the
fractured article of the wood more tightly. These studs or points aro
not used in the grips intended for ironwork and machinery; the grips

page_text: are then free from projections on the inside. The same grip will fit
bars of different sizes since it is to a great extent the length of the
cross bolts that limits and varies the capacity of the grips more than
their actual circumference. . Besides this advantage, the grips may
be
made of any size, of any length, and of any capacity.
In cases where the projecting bolts may be considered as objectionable,
as when being used for fastening a broken carriage pole, in these
instances the place of the cross bolts and eyes is supplied by bolts split
horizontally, each half bolt being placed perpendicularly on the edge
of the grip where it meets when closed and exactly opposite to its 1
corresponding half, so that the two points of the halves or split bolts
meet at the top and form one entire bolt. These bolts being tapped
admit of the nuts being screwed on them, and as they are screwed they
gradually increase the pressure on the object held inside the grip and
fasten it firmly and securely.
]
Another and not less important application of the grip in its appliance
to surgical purposes. When applied to this purpose they are of a thinner
material and of a proportionate size and shape, so that they may be
used as spirits for broken limbs. They will prevent the bones from
setting otherwise than straight. The ordinary wooden splints which are a
now employed are faulty in this respect, since they not unfrequently
cause the broken or fractured limb to set crookedly.
And, lastly, the grip may be fastened by means of bolts running
through eyes on each side of the grip where it closes and fastened with
screw nuts at each end.
In witness whereof, I, the said James Gurrin, have hereunto set
my hand and seal, this Eighteenth day of April, in the year of
our Lord One thousand eight hundred and seventy-two.
