PROVISIONAL SPECIFICATION.
Improvements in Bell Punches for Punching Tickets.
I, JOHN MACRAE, of 10 Richmond Street, in the County of Glasgow, North
Britain, Watch and Clock Manufacturer, do hereby declare the nature of this
invention to be as follows, that is to say :-
My said invention has for its object to improve the construction of certain parts
of bell punches so as to render such parts more durable and less liable to get out of
order than as commonly made.
'My improvements are applicable to the bell mechanism of the punch. The
clapper is as usual on the end of a small lever which is centered on a fixed pin and
which is formed with an oval boss. A steadying lever centered on a fixed pin at a
little distance from the clapper pin and acted on by a spring bears on the boss of
the clapper lever, the bearing part being concave to fit or nearly fit on the oval
boss. The punching lever is constructed to act on the clapper lever in the usual
manner, and when the latter is acted on the turning of its oval boss moves the
steadying lever, but after the stroke on the bell the steadying lever is moved back
by its spring and moves or holds the clapper steadily in position ready for the next
action.
Dated this Twenty-first day of May 1895.

Improvements in Bell Punches for Punching Tickets.
1, JOHN MACRAE, of 10 Richmond Street, in the County of Glasgow, North
Britain, Watch and Clock Manufacturer, 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 :-
My said invention has for its object to improve the construction of the mechanism
for sounding the bell of bell punches so as to render such mechanism more durable
and less liable to get out of. order than as commonly made. The improved
mechanism also prevents employés ringing the bell without at the same time.
punching the ticket.
And in order that my said invention may be properly understood I have
hereunto appended an explanatory sheet of drawings, whereon :-
Fig. 1 is a view showing the mechanism applied to an ordinary bell punch.
Fig. 2 is a view showing the mechanism as it appears when a ticket is being
punched.
Fig. 3 is an enlarged view of the mechanism with the clapper g and lever h
removed.
a is the ordinary lever, b the punch, c the catch, e the spring and f the receptacle
for the punched out pieces of tickets.
The clapper g is, as usual, on the end of a small lever h which is centered on a
fixed pin whose boss has a catch j and a catch k on it. The end of the long bent

an upwardly projecting tail piece m on an oval or cam shaped boss or collar n
which works on the pin i. A steadying lever'o centered on a fixed pin p at a
little distance from the clapper pin i and acted on by a bent spring a bears on the
collar n, the bearing part being concave to fit or nearly fit on the oval face of the
collar. The punching lever a is constructed, as usual, with a long tooth a' which
is capable of entering the recess & in the front of the oval collar or cam n.
The spring catch c is preferably made with two steps c¹, c², as shown.
The operation of the mechanism is as follows :-
с
After a ticket has been inserted in the jaw t so as to knock away the spring
catch c the lever a is depressed in order to punch the ticket, and, in so doing, the
tooth a catches in the recess s of the cam n and causes the latter to turn, against
the action of the springs and g. When the cam n moves, its tail piece m raises
up the clapper 9 until finally the latter -reaches the position shown at Fig. 2.
Immediately the tooth a', in its downward movement, clears the recess s the
spring forces down the clapper 9 sharply and causes it to ring the bell.
Immediately the bell has been rung the steadying lever, under the action of the
spring 9, holds the can and through it also the clapper lever steadily in position
ready for the next action.
The mechanism is so arranged, as shown, that before the tooth a' clears the
recess s, so as to allow the bell to ring, the punch 6 has perforated the ticket.
The mechanism can be arranged to suit other forms of punches besides the one
shown on the drawings.
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
consider novel and desire to claim is :-
Mechanism for ringing the bell of bell punches constructed and arranged
substantially as hereinbefore described with reference to the drawings annexed.
