IMPROVEMENTS IN APPARATUS FOR LOCKING MOTTIES OR CHECKS TO PIT CORVES OR OTHER SIMILAR WAGONS
Year: 1884

page_text: I, WILLIAM CALOE of N° 147 Eastwood Lane Rotherham in the County of
York Slater, do hereby declare the nature of my Invention for IMPROVEMENTS
IN APPARATUS FOR LOCKING MOTTIES OR CHECKS TO PIT CORVES OR OTHER
SIMILAR WAGONS, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, that is
to say :-
My Invention relates to improvements in the means of, and apparatus for locking
the motties, checks or tallies, used by miner and other labourers, to the pit corves,
or other wagons or vehicles used by them in their work, in order to distinguish
such corves or wagons, so that the work may be placed to the credit of the right
man. Hitherto the means employed to secure motties or checks have been so
insecure that they have often been lost, causing much inconvenience, and ill-feeling.
In carrying out my Invention, I construct a strong metallic case or lock to
which the mottie can be attached in a moment by simply pressing it into a recessed
portion, where it is firmly and securely held by the action of the lock; and in
order that my Invention may be fully and clearly understood, I shall refer to the
annexed Sheet of Drawings and to the letters and Figures marked thereon, the
same letters of reference indicating the same parts in all the Figures.
Fig. 1. represents the lockcase with the mottie or check attached.
Fig. 2. is a cross section of the same.
Fig. 3. is the back of the lockcase with the various parts of the lock shown in
dotted lines.
Fig. 4. shows the parts of the lock that are fixed to the front plate of lockcase.
Fig. 5. shows the parts attached to the back plate.
Fig. 6. is the unlocking key.
A is the lock case, B is the mottie or check, C is a catch projecting from the back
of the mottie, which when pushed through a corresponding hole in the centre of
the case, engages with the catch or latch D as shown in Figs 2 and 4; the latch
is held down by the spring F, and lever E, and the mottie is thus held secure until
the latch.is raised, which can only be accomplished by means of the key Fig. 6.
G is the keyhole, which I close directly the key is withdrawn by means of a closing

page_text: piece H, which fits round the pin I, and prevents the entrance of dirt; the closing
piece slides upon two short rods and is forced forward by the spring K.
When the mottie is to be removed, it is only necessary to turn the key which
raises the latch, and releases the catch C; the spring and pushplate L, which were
compressed by the catch when the mottie was pushed into its place, is now free to
exert its power, and pushes the mottie out of the recess; the edge of which protects
it from being forced off by accident or otherwise.
The lock and case is easily attached to the side of a pit corve or wagon by
means of bolts passed through the holes M.
The modus operandi is briefly this, when a corve is filled, the miner takes a
mottie, and forces the catch into the centrehole of the lock, which is closed to
protect it from dirt by the plate and spring L, the spring being thus compressed.
When the corve reaches its destination the weightman takes the weight, and
then unlocks the lock; directly the latch is raised sufficiently to release the catch,
the mottie is forced out from the recess in the case by the action of the spring, and
falls into the man's hand.
My improved apparatus prevents changing or tampering with motties and is a
simple and effective way of attaching and securing them to the sides of corves or
other wagons.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
The apparatus for securing motties or checks to the sides of pit corves, or other
wagons, substantially as described and illustrated.
