PROVISIONAL SPECIFICATION.
A Combination Raising, Lowering, and Fixing Apparatus, applicable
to Cords, Wires, and the like.
ALBERT ROBERT BURNELL Railway Clerk 20 The Greenway Uxbridge
Middlesex do hereby declare the nature of this invention to be as follows:-
A projecting block, having attached thereto a double lever, so jointed that the
cord or other thing attached thereto, & passing over a pulley fixed above it,.
may be lowered or raised fixed by one operation & by one movement without
any catch, spring, or other fixing.
The levers consist firstly of a rigid bar hinged at top to the projecting end of the
block and, secondly, a lever or loop of thin metal or wood made so as to fold over
the rigid bar, and attached to the latter near the handle or bottom end. The two.
levers on being folded together tighten any line which may be properly affixed to
the upper end of the thin lever or loop, and on being pushed back the knuckle
joint of the two levers passes below the centre of the projecting block, the thin
lever passes behind the rigid lever & any strain caused by the line exerts a fixing
pressure on the levers.

I, ALBERT ROBERT BURNELL of 20 The Greenway Uxbridge in the County
of Middlesex, Clerk in Audit Office Great Western Railway 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 apparatus consists of a rigid bar or lever hinged at the top to the projecting
end of a block and a lever or loop of thin metal, woud, cord, or the like, made so
as to fold over the rigid bar, attached to the latter near the handle or bottom end.
A is the rigid bar or lever preferably made of metal or wood.
B is the block, preferably made of metal, capable of being fixed at B2 to a wall,
post, or the like.
C, is the thin lever or loop, made of material capable of bearing tensile strain,.
preferably made of wire, and preferably of the loop form shewn, but in cases where
no great strain is required to be placed upon the lever A a single wire, cord, or the
like will be sufficient, and in such cases the lower portion of the cord wire
or the like which it is intended to operate may be attached direct to lever A at
point A².
A³ is a handle for convenient working but not essential to the apparatus. The
handle may be a continuation of A as shewn or a separate piece attached to
lever A by a hinge or the like.
The lever A is hinged to block B at B'. The thin lever or loop C is hinged or
pivotted to A at A' preferably by means of a rivet and washer. C2 is an eye in

page_text: lever or loop C to which is to be attached the cord wire or the like which it is
required to raise or lower and fix.
The action of the apparatus is as follows:-The block B being fixed to a wall,
post, or the like, on the lever A being depressed, the lever or loop C folds with it
and so tightens or raises any cord wire or the like which, coming from a pulley
fixed over the block, may be affixed to the eye C³ and on the lever A being pushed
back against the wall, post or the like to which the block B may be fixed, the joint
at A² passes below the point B' of block B, the lever or loop C thereupon passes
to the wall or post side of lever A and any upward strain caused by the cord wire
or the like, brings the lever A at point A² against the wall or post, which,
preventing further progress of lever A, causes the cord wire or the like to become
fixed.
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 raising lowering and fixing apparatus applicable to cords wires and the like;
a combination of block and folding levers, or, as a modification, of block and lever,
substantially as described and for the purposes herein set forth.
A. R. BURNELL.
