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 wheel, with four or other number of catches formed
upon the wheel, so that each catch will engage one way with any article brought in
contact with it the catch wheel is mounted in suitable bearing brackets, in which is
placed a spring catch which enters a recess formed in one side of the catch wheel,
and prevents it from turning one way until operated by a suitable arrangement of

DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation of our improved catch for securing corves.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is an enlarged sectional detail of catch box and spring.
Fig. 4 is a front elevation in section showing catch wheel with two recesses.
Fig. 5 is a front elevation in section showing catch wheel with four recesses.
Our invention consists of a catch wheel A, with four or other number of catches B
formed upon the wheel, so that each catch will engage one way with any article
brought in contact with it.
The catch wheel is mounted in suitable bearing brackets C, upon one or both
bearing brackets is formed a box or receptacle H in which is placed a spring catch D,
(adjustable by means of a screw G) which enters or engages with a recess E in one or
any number of the arms B of the catch wheel A, a tension spring placed between the
bearing bracket and the wheel, keeps a proper tension upon the catch wheel, and
prevents it from turning one way until operated by a suitable arrangement of lever or
levers F, which withdraw the spring catch D, and release the catch wheel A, allowing
the article engaged to be withdrawn, the catch returning self actingly.
This invention is specially applicable for securing the corves in the cages of coal
and other mines, and may also be used as a safety catch in the head gear in the case
of pulleying, when two of the said catches are required, or it may be used as a safety
catch generally.
Also it may be used on inclines as a safety catch in case of rope breaking, so
preventing the corves from running. Also for railway sidings to prevent full trucks
from getting into the points, and it may be used for any other suitable purpose.

page_text: Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, we declare that what we claim is :-
1. The use and employment of a catch wheel A, with arms or catches B, and
recesses E therein, in which a spring catch D engages, so that the wheel is loose one
way and fast the other, for the purposes, substantially as shown and described.
2. The combination of the catch wheel A with tension spring J, and spring catch D
within the box H, substantially as shown and described.
3. The spring catch D within the box H, adjustable so as to allow of the renewal of the
spring, substantially as shown and described.
