PROVISIONAL SPECIFICATION.
Apparatus for Controlling Corves on Tramways or upon Pit Cages,
Hoists, or the like.
We, JAMES M° BEAN, of Thurnscoe near Rotherham in the County of York,
Engineer, and JOHN EATON, of Thurnscoe aforesaid, Colliery Manager, do hereby
declare the nature of our invention to be as follows:-
Our invention has for its object to control, retain, and release one or more
corves as may be pre-arranged either upon a line of tram rails, or upon a cage,
hoist, or the like, and the apparatus by which this is effected is of very simple
construction.
In its application to a tramway for example, we fix the apparatus between the
rails upon any suitable foundation such as a couple of strong transverse joists or
sleepers.
It consists of a revolving barrel upon a short square axle supported in a pair of
bearings and capable of revolving freely therein. The barrel consists of a central
cam or snail, and two outside flanges, each consisting of four arms (for example,)
so arranged and of such a length that the axle of a passing corve will come in
contact with the top arm of each flange so as to cause it to revolve if not otherwise
secured.
Below the barrel and the rails we fix a rocking shaft in suitable bearings one
end projecting beyond the rails, upon which end a hand lever, or other arm or
lever, may be fixed for actuating the shaft either directly or from a distance.
Upon the said shaft between its bearings, we fix a short vertical arm or catch,
capable of resting against and of engaging with the shoulder of the cam or snail
upon the barrel; and it is caused to engage by the action of a counter balance
weight, or by a spring if preferred.
To retain the four armed flanges in the desired positions, and to prevent over-
running, we fix a spring so as to press upon the square part of the barrel shaft, its
tendency being to retain the shaft in four positions, namely, when it is acting upon
the flats.
An apparatus such as described will permit only two corves to pass, and will then
automatically stop any following corves; for example, suppose a dozen detached
corves are being held upon an incline by the apparatus, the front axle of the first
corve being in contact with the top arms of the barrel. The lever is now drawn
back either by hand, or from a distance by wire, which removes the catch from
under the shoulder of the cam. The barrel is now free to revolve and the pressure
of the corve moves it round, the second arm coming into position, this is struck
by the back axle and the third arm is turned up, the two axles of the next corve
repeat the action and complete the revolution of the barrel, bringing the shoulder
of the snail upon the top of the catch.

JAMES MBEAN Rosslyn House Thurnscoe Rotherham JOHN EATON Rosslyn
House Thurnscoe near Rotherham 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 has for its object, to control, retain, and release one or more,
corves, trams, or wagons as may be pre-arranged either upon a line of tram rails
or upon a winding cage, hoist or the like and the apparatus by which this is
effected is very simple of construction.
In its application to a tramway it is fixed between the rails to any suitable
foundation sufficiently strong to keep same in position.
It consists of a revolving barrel or star wheel fitted upon a short axle or shaft
supported in a pair of bearings and capable of revolving freely therein the barrel
or star wheel consists of a central cam or snail so arranged and of such a length
that the axle of a passing corve, tram, or wagon will come in contact with the
top arm of each flange so as to cause it to revolve if not otherwise secured.
Below the barrel or star wheel and the rails we fix a rocking shaft in suitable
bearings one end projecting beyond the rails upon which end a hand lever or other
arm or lever may be fixed for actuating same.
Upon the said shaft between its bearings we fix a short vertical arm or catch,
capable of resting against and of engaging with the shoulder of the cam or snail
upon the barrel or star wheel; and it is caused to engage by the action of a
counter balance weight, or by a spring if preferred.
To retain the star wheel in position and to prevent over-running, we fix a spring
so as to press upon the square part of the barrel shaft, its tendency being to retain
the shaft in four or more positions namely when it is acting upon the flats.
An apparatus such as described will permit only two corves, trams or wagons to
pass and will then automatically stop any following, corves, trams or wagons for
example suppose a dozen detached corves, trams, or wagons are being held upon an
inclined plane by the apparatus, the front axle of the first corve, tram or wagon
being in contact with the top arm of star wheel or barrel, the lever is now drawn
back either by hand or other means which removes the catch from under the
shoulder the shoulder of the cam the barrel or star wheel is now free to revolve
and the pressure of the corve, tram or wagon moves it round, the second arm
coming into position, this is struck by the back axles of the next corve, tram, or
wagon repeat the action and complete the revolution of the star wheel or barrel,
bringing the shoulder of the snail upon the top of the catch.
And in order that our invention may be understood and carried into practical
effect we have annexed to this specification the accompanying drawing and the
figures and letters of reference marked thereon we now refer.
