We do hereby
declare the nature of this invention to be as follows:-

DESCRIPTION.
Their are two kind of blocks rope and chain blocks our invention is an improved
rope block.
Rope blocks can either be made of wood or iron which are used for the
purpose of tackle to gain purchase or power for lifting or moving weight of any
description.
Blocks are composed of sheaves or cheeks which are bolted or riveted together;
having hoops or stays placed between the sheaves or cheeks to make a partion for
the pulleys to revolve in.
The pulleys are grooved & work on a axcle which join the sheaves being
supported by the cheeks & the sheaves or cheeks at the same time prevent the
rope from slipping out of its place.
What we do hereby claim is.
Ist. The peculiar shape of the groove or recess in the pulley where the rope
works.
II. A catch or arm or camb which grips the rope that is raising the weight and
prevents or holds it in the position required thereby preventing it slipping back to

An Improved Rope Block for Lifting or Hoisting Weights of Any
Description.
We, WILLIAM HAYHURST of 1, Catlow Street Burnley, Lancashire, Cramp
Maker, and ELLIS CROSSLEY of Hemingfield, near Barnsley, Yorkshire, Moulder,
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 :-
Our invention consists of a catch or arm which is so arranged as to clip the rope

page_text: and pulley or stud of the block to prevent the rope from slipping back when the
weight is suspended.
The catch may engage with a lip or recess on, the flange of the pulley or
otherwise, so as to hold the rope and pulley at any required time. The catch may
fall into the recess or against the lip on the pulley by the action of a spring or it
may fall merely by its own weight. During the raising and lowering of goods, the
catch is held out of action by pulling a cord or chain attached to it.
The flange of the pulley may be of any suitable formation or shape, so long as
the said catch is capable of holding the rope and pulley firmly.
In the accompanying drawings,
Fig. 1 is a side elevation and Fig. 2 a front elevation. of a rope or pulley block
constructed in accordance with our invention.
A is the pulley formed with a lip or recess B, against or into which falls by
gravity or spring pressure catch C, so as to interrupt further movement of the
pulley and rope. During the raising and lowering of goods this catch is disengaged
from the said lip or recess by pulling cord or chain D. The said lip or recess B is
preferably formed on the flanges of the pulley, and catch C made to stride the
same as seen in Fig. 2.
Fig. 3 is a detached view shewing clearly pulley A formed with a lip, swell or
recess B, into which falls catch C on the cord or chain D being released.
Fig. 4 illustrates another form of pulley having flattened edges E, on which
catch C (in this instance suitably shaped) may fall to arrest further movement of
the pulley as described, or the particular shape of the pulley for this purpose may
be modified in various ways.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
The use and application of a catch or arm to a rope or pulley block for the
purpose of arresting the motion of pulley and rope when and as required,
substantially as described, and illustrated.
