PROVISIONAL SPECIFICATION.
Improvements in Bolt and Rod Cutters.
1, WILLIAM MARCH. of 69 Adelaide Road South Hampstead London
Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
My said invention has for its object the cutting of metal bolts, rods or other
Buch like hard materials.
The invention resembles a pair of shears & consists of two flat steel cutters
both of which are sharpened at their inner edges and are pivoted by set screws
which pass through them and through a pair of top & bottom plates. The extent
of movement of the two cutters is inade to correspond with each other by reason
of being geared together at their inner edges, the teeth being between the two
pivots & in a line therewith.
Each of these cutters is operated on by a handle. At the cutter end of both of
the handles is a female joint which receives the prolonged end of the cutters & are
secured thereto by set screws.
The handles are connected by a pair of male & female jointed eyebolts which
screw into the handles. The set screw which unites the eyebolts forms the fulcrum
of the lever handles.
The object of connecting these handles by jointed eyebolts is to allow of
compensation for the wear of the cutters, the knife-edges of which are brought
nearer together in proportion as their prolonged ends are forced asunder by partly
unscrewing the eyebolts.

COMPLETE SPECIFICATION.
Improvements in Bolt and Rod Cutters.
1, WILLIAM MARCH of 69 Adelaide Road, South Hampstead in the County of
London, Mechanical Engineer 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:-
The objects of this invention is the cutting of metal bolts, rods or other such
like materials, and consists of two flat steel cutters a, shown in Figures 1 & 2.
These cutters are sharpened at their inner edges and are pivoted together by
set screws 6 which pass through them and through a pair of link plates b, one on
each side of the cutters. The movement of each cutter is made to correspond
with the other by teeth being cut in them and which gear into one another. Each
of these cutters is operated by a lever handle d fulcrumed at 9 and acting on the
prolonged end of the cutters. At the cutter end of each handle is a swivel joint e
which receives the prolonged ends of the cutters and are secured thereto by set
screws e. The handles are connected by a pair of jointed eyebolts of which are
screwed into them in such a way as to be adjustable. The set screw g which unites
these eyebolts forms the fulcrum of the handles. The object of connecting the
handles thus is to allow of compensation for wear of the cutters, the knife edges
of which are brought nearer together in proportion as their prolonged ends are
forced asunder by partly unscrewing one or both of the eyebolts, after liberating

page_text: them by removing the set screw g. The two set screws i, i, are for the purpose of
regulating the travel of the handles d, d, and of stopping them at the required
distance.
:
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
-claim is :
In a bolt or rod cutter the combination with the two levers carrying the cutters
of the adjustable eyebolts secured to the said levers and pivotally connected
together, substantially as described.
