PROVISIONAL SPECIFICATION.
Improvements in Wedges for Mining, Raising Weights, or similar
Purposes.
GEORGE BURNSIDE No. 24 Railway Terrace North Newherrington near Fence
Houses Co. of Durham, miner do hereby declare the nature of this invention
to be as follows:-
I have two half round plates, three feet in length and the two together is three
inches in diameter with a tapered circular grove inside the two plates, is placed in a
drill hole three inches in diameter, in the Rock or Coal, which is prepared for the
same, and a tapered round wedge har, three feet in length with a taper of one inch
diameter at one end and three inches diameter at the other end is placed one foot six
inches in between the two plates and then it is tight, with the one inch end inverse,
and then it is forced one foot six inches further in by a blow from a hammer or by a
screw spindle in between two rods, the two rods to be pinned, onto the out end of the
two plates, and a nut is fixed in between the two rods, for the screw spindle to work
through to go against the end of the tapered round wedge har to force it in between
two plates, to expand the two plates apart one inch to detach the rock or Coal and the
screw spindle is worked by a ratchet brass handle, by having the two plates circular
groved out and the round wedge bar the only friction is in the circle inside the two
plates and on the round wedge bar.
The use of the Apparatus improvements in wedges for mining, raising weights or
similar purposes,
is for to split rock, stone Coal, or Wood, and to lift any great weight
from the ground, by placing the apparatus beneath, the weight and by working it as
above mentioned.

I GEORGE BURNSIDE of 24 Railway Terrace North New Herrington Fence Houses
Co. of Durham, miner do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
Two half round plates C. with a tapered circular grove D. in the flat side of each
plate with a lug E. on the end of each plate C. made of steel or iron F. a tapered
round wedge bar also made of steel or iron, steel screw driving bar G. and crosshead
nut H. I. two links J. coupling and K. two pins ratchet brace lever, M. also made of
stcel or iron. A hole is bored in the mineral which is to be split and the two plates C.
is inserted in the hole up to the lugs E. and the tapered round wedge bar F. is
inserted midway in the groove D. between the two plates C. and then it is propelled
by a blow from a hammer or by the screw driving bar G. with a crosshead nut H.
the two links I. is attached on to the two lugs E. by the two pins, K. and the nut H is
fixed between the two links I. by the screw driving bar G. and the nut H. been so
fixed onto the two links I. and the links I. onto the two lugs E. it takes its bearings
to propel the wedge bar F in between the two plates C. the screw driving bar G.
and wedge bar F. is connected together by the coupling J. which as a square hole in
one end to fix onto the square L. and the other end to have a round hole in, to fix on
the round end N. of the wedge bar F. also forming a washer against the shoulder O.
the ratchet brace lever M. is attached on the square L2 and by the working of the.
ratchet lever M. the screw driving bar G. and coupling J. is revolved which brings
the wedge bar F. forward in between the two plates C. expanding the plates C. as it
goes forward, by this means, splitting the coal rock or wood or raising the weights to
make the machine ready for another operation, we take the ratchet M. off the screw G.
and then the two links I. is taken off the two lugs E. the screw driving bar G. off
the coupling J.
Having now particularly described the nature of my said invention and in
what manner the same is to be performed I declare that what I claim is.
(1) The tapered round wedge bar F. and two half round plates C. with a tapered
circular groove D. in the flat side of each plate C. so as to reduce the sliding surface::
of the wedge bar F. on the plates C
(2) The screw driving bar G. taken its bearings on the two lugs E. by been so

page_text: connected with the two links I. to propel the wedge bar F. forward between the two
plates C. and expanding the plates C. at the same time.
(3) The coupling J. also forming a washer against the shoulder O.
(4) The tapered round wedge bar F. been also applicable to be propelled in
between the two plates C. by a blow from a hammer, also expanding the plates C. at
the same time.
