PROVISIONAL SPECIFICATION.
Improvements in Time Checking Apparatus.
T. JOHN LORIMER CORBETT, of 65, Jamaica Street, in the City of Glasgow,
Watchmaker, do hereby declare the nature of this invention to be as follows:-
This invention is a further development of the improvements in time checking
apparatus described in the Specification of Letters Patent granted to me No. 18528
of 1896, and it has for its object to better adapt such apparatus for use in works
in which large numbers of workmen are employed.
In practice it is found that the workmen who arrive early or in time largely
exceed the number who are late, and as crowding takes place in entering ton
much time is taken up in entering the individual tallies through a narrow slit.
By the present improvements I provide a separate hopper or hoppers opened and
closed by the time cheeking clockwork which operates the deffector to distribute
or direct the allies of the late arrivals, the said hopper or hoppers when opened
hy the clockwork being adapted to receive and pass through large numbers of
tallies which may be merely dropped into it and being closed by the clockwork
when the due time for arrival of the workmen has elapsed whereupon the slit and
deflector devices described in my specification above referred to are brought into
operation to check the arrival of late comers only.
In one modification the hopper may assume the form of an open box with sloping
sides whereinto the tallies are dropped by the workmen in passing the apparatus,
the box being formed with a sliding or other movable bottom or side door through
which the tallies fall into a drawer or receptacle below. The sliding or movable
door is operated either directly or through a lever from the deflector or from the
running train of the clockwork. It is thereby opened to permit of the passage
through the hopper of the tallies of workmen arriving in due time, and it is closed
on the lapse of the period of grace usually allowed so that no further tallies may
pass through. The workmen arriving later must then pass their tallies through
the slit provided in the apparatus so that they may be distributed by the operation.
of the deflector, as described in my specification before referred to, into separate
compartments which are arranged to check the time of late arrival.
In another modification the hopper is made in the form of a large bowl having
a central crifice in the bottom for the passage of the tallies, and a conical valve
adapted to be raised or lowered vertically to open or close the orifice. This
arrangement ensures that the workmen may readily see if their tallies drop
through the howl into the receptacle below. The conical valve is carried upon a
vertical spindle whose lower end may be carried in a footstep fitted with an anti-
friction roller resting on a disc rotated by means of gearing from the running
train of the clockwork, the disc being formed with a cam surface which as it
comes round raises the spindle to close or open the valve and after passing opens

page_text: or closes it as may be arranged. The later arrivals may be checked by the use
of the slit and deflector; but under a further modification the latter arrangement
may be dispensed with by using a number of bowl like hoppers each provided with
a valve carried by a spindle resting on a cam disc rotated from the rotating train..
The discs are geared to rotate together but the lifting cams on them are situated
at different points so that whilst the valve of one hopper is open to permit of the
passage of the tallies the others are closed and each is opened in succession.
Receptacles for the reception of the tallies are placed under each hopper and by
this means the tallies of the early arrivals drop through one hopper into the early
receptacle, and those of the late workmen into other receptacles according as one
or other of the several hoppers is opened by the clockwork for the passage of the
tallies.

I. JOIN LORIMER CORBETT, of 65, Jamaica Street, in the City of Glasgow,
Watchmaker, 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:-
This invention is a further development of the improvements in time checking
apparatus described in the Specification of Letters Patent granted to me No. 18528
of 1896, and it has for its object to better adapt such apparatus for use in works
in which large numbers of workmen are employed.
In practice it is found that the workmen who arrive early or in time largely
exceed the number who are late, and as crowding takes place in entering, too
much time is taken up in entering the individual tallies through a narrow slit.
By the present improvements I provide a separate hopper or hoppers opened and
closed by the time checking clockwork which operates the deflector to distribute
or direct the tallies of the late arrivals, the said hopper or hoppers when opened
by the clockwork being adapted to receive and pass through large numbers of
tallies which may be merely dropped into it and being closed by the clockwork
when the due time for arrival of the workmen has elapsed whereupon the slit and
deflector devices described in my specification above referred to are brought into
operation to check the arrival of late comers only.
The invention is illustrated by the accompanying drawings, Fig. 1 being a
transverse vertical section of one form of that part of the time checking apparatus
which constitutes the improvement. Figs. 2 and 3 are front elevation and trans-
verse vertical section of two other modified forms of the improvement, and Fig. 4 is a
detail of part of Fig. 3 hereinafter particularly referred to. Figure 5 is a front
elevation of a clock shewing the position thereon of the early and late tally
hoppers.
In one modification, illustrated by Fig. 1, the hopper A, which is intended to be
placed in front of the receptacle containing the deflector referred to in Patent

page_text: No. 18528 of 1896, may assume the form of an open box A with sloping sides
whereinto the tallies are dropped by the workmen in passing the apparatus, the
box being formed with a pivoted door B or with a sliding or other movable bottom
or side door through which the tallies fall into a drawer or receptacle below. The
pivoted sliding or movable door is operated either directly or through a lever or
rod C from the deflector which in this case is provided with a cam surface to
act on a roller C centred in the rod C or the door may be operated from the
running train of the clockwork. It is thereby opened to permit of the passage
through the hopper A of the tallies of workmen arriving in due time, and it is
closed on the lapse of the period of grace usually allowed so that no further
tallies may pass through. The workmen arriving later must then pass their tallies
through the slit J provided in the apparatus so that they may be distributed by
the operation of the deflector J shewn at Figure 3 as described in my specification
before referred to, and shewn at Fig. 2 of that specification, into separate com-
partments which are arranged to check the time of late arrival.
In another modification, illustrated by Fig. 2, the hopper is made in the form
of a large bowl D having a central orifice D¹ in the bottom for the passage of
the tallies, and a conical valve E adapted to be raised or lowered vertically to open
or close the orifice D'. This arrangement ensures that the workmen may readily
see if their tallies drop through the bowl into the receptacle below. The conical
valve E is carried upon a vertical spindle F whose lower end may be carried in
a footstep or a guide G the spindle being fitted with an antifriction roller resting
on a disc H rotated by means of gearing from the running train of the clockwork,
the disc being formed with a cam surface H' which as it comes round raises the
spindle F to close, or lowers to open the valve E and after passing opens or closes
it as may be arranged. The later arrivals may be checked by the use of the slit
and deflector, shewn at Fig. 3: but under a further modification the latter
arrangement may be dispensed with by using a number of bowl like hoppers D
each provided with a valve E carried by a spindle resting on a cam disc rotated
from the rotating train. In this case the discs would be geared to rotate together
but the lifting cams on them situated at different points so that whilst the valve
of one hopper is open to permit of the passage of the tallies the other are closed
and each is opened in succession. Receptacles I, shewn at Fig. 3, for the recep-
tion of the tallies are placed under each hopper and by this means the tallies of
the early arrivals dron through one hopper into the early receptacle, and those
of the late workmen into other receptacles according as one or other of the several
hoppers is opened by the clockwork for the passage of the tallies.
In the modification shewn at Figs. 3 and 4, instead of the vertical spindle a bent
lever 3 is used for carrving the valve E, said lever F3 being pivoted at F2, and
some of the weight of the valve is taken up by a spring or by a weight. The
valve E is locked in its closed position by a pivoted locking piece L shewn particu-
larly at Figure 4, which engages the free end of this lever, which locking piece is,
upon the movement of the deflector or the time checking clockwork which
actuates the deflector. withdrawn from the end of the lever whereby the valve E
is lowered to permit of the entrance of the tallies into the receptacle.
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:-
1. In time checking apparatus, the combination, with receptacles for receiv-
ing the checks or tallies and a deflector operated by clockwork mechanism, of a
hopper having a sliding or pivoted door operated from said deflector, substantially
as and for the purpose set forth.
2. In time checking apparatus the combination, with a receptacle or receptacles
for receiving the checks or tallies of one or more open bowl-like hoppers each
having its outlet orifice fitted with a valve which is adapted to be raised or lowered

page_text: to close or open said orifice at a predetermined time by the action of time checking
clockwork substantially as and for the purpose set forth.
Dated this 6th day of April 1899.
