PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Checking or Indicating the Time of
Arrival and Departure of Workpeople.
I, FRANK BROOK of 9ª Market Street, Huddersfield, Yorkshire Watchmaker
do hereby declare the nature of this invention to be as follows:-
This invention refers to mechanism for checking or indicating the periodical
arrival and departure of employées.
In carrying out my invention I employ, by preference, an ordinary eight days
clock, and from the hour or minute wheel or shaft thereof I transmit motion to a
disc or discharge wheel or plate mounted on a stud secured to the frame of the
clock, which is rotated to the extent of one revolution to every twenty four
revolutions of the minute wheel. The said disc is marked off into divisions each
representing five minutes or other fractional periods of time, and holes are punched
or drilled at each division for the reception of studs or pins whose number and
disposition on the said discharge wheel is determined by the times at which the
checking or indicating is required to take place. I also use the ordinary striking
mechanism of the clock and connected with the levers for setting said mechanism in
action is a lever arm having a suitably formed end which is adapted to be engaged
by the pin or pins on the discharge wheel as the latter revolves, and to release the
aforesaid levers so as to give the alarm. When said levers are operated thus, the
coiled spring within the barrel connected with the striking mechanism causes the parts
to be rotated until the cam or snail has completed a revolution, when it is again
engaged by one of the levers and further movement of the escapement prevented
until a second pin on the discharge wheel again actuates the lever arm and releases
the mechanism. To the spur wheel mounted on the axis of the spring barrel is
geared a pinion mounted on a short shaft carrying a bevil wheel gearing with
another bevil secured to one end of a vertical shaft. The partial rotation of the
said spur wheel as set forth causes the pinion, and also the upright shaft through
the medium of the bevil wheels, to be rotated to the extent of one revolution.
Mounted loosely on the lower end of the upright shaft is a pinion gearing into
teeth formed on the outer edge of a wheel or frame made with recesses or divisions
to receive twelve or other suitable number of loose boxes into which the employées
checks or tallies are to be deposited.
The said pinion is provided with a stud, finger or key with which engages the end of
a sleeve or hollow shaft secured to the upright shaft so as to turn therewith but
which is free to be slided up or down the shaft. When the sleeve is engaged with
the stud or key, the pinion revolves with the upright shaft and causes the frame or
drum to be rotated to the extent of one box so as to bring a second box or division
of the drum under the "shoot" into which the employées deposit their checks, and
this change of boxes or divisions is effected each time a stud or pin on the discharge
wheel engages the lever arm connected to the levers of the striking mechanism.
The boxes or divisions of the drum or frame may be marked to accord with the
time or times at which they are brought under the "shoot," and they are
removeable at will. In cases where the number of checks expected to be deposited
in one or other of the boxes exceeds the capacity of said box or boxes, an opening
is made in the bottom of same through which the checks pass into a receptacle
underneath. By sliding the sleeve out of engagement with' the pinion on the
upright shaft, the wheel or drum can be turned round without disturbing the
clockwork, from which it is thus disconnected.

page_text: Instead of effecting the periodical partial rotation of the drum or frame through
the medium of the striking mechanism in the manner set forth, I may establish an
electric connection between the lever arm or levers of the striking mechanism and
an electro magnet or magnets situated under the drum or frame, which latter, each
time the circuit is completed by the engagement of a pin or stud on the discharge
wheel with the lever arm, release the drum and allow it to be partially rotated by
a weight suspended from the end of a cord or chain wound onto the drum or its
axis. The electro magnets are arranged so that when one end is withdrawn from
engagement with the frame or drum, the opposite end is raised and engages with
the drum when it has moved to the extent of one box; or the magnet may be
withdrawn entirely to release the drum, and return to its original position before
the requisite movement has been completed.
The completion of the circuit may otherwise be effected by a cam on one of the
shafts of the striking mechanism acting on a lever so as to raise it to make the
connection, the said lever being held in connection for a longer or shorter period
by lengthening or shortening the "dwell" of the cam.
Where the drum or frame is situated at some distance from the clock, the use of
an electric connection or connections for releasing the drum at stated periods is of
advantage.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Checking or Indicating the Time of
Arrival and Departure of Workpeople.
I, FRANK BROOK, of 9ª Market Street, Huddersfield, Yorkshire, 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 refers to mechanism for checking or indicating the periodical.
'arrival and departure of employees.
In order that the said invention may be fully understood reference is hereinafter
had to the annexed sheets of drawings and the letters of reference marked thereon..
Fig. 1 is front elevation of my improvements as applied to and operated by the
mechanism of an eight day's clock. The clock face or dial is removed and the
minute and hour hands and the gearing for actuating the hour hand are shewn in
dotted lines for the sake of clearness.

case or shell.
Fig. 6 is front elevation of same.
Fig. 7 is a detail of receiving box..
I
Figs. 8, 9, and 10 illustrate three different arrangements for releasing the drum
or frame at stated intervals of time by electrical connection with the clockwork.
Referring to the drawings a represents the framework of the clock, b the arbor
or shaft on which the hour wheel c is mounted, said hour wheel gearing with
wheel d and receiving motion from the ordinary mechanism of an eight day's clock,
which being well known, is not shewn on the drawings.
'
On the bour wheel arbor b. is mounted a pinion e which gears, into, and drives a
disc or discharge wheel or toothed, plate f mounted on a stud secured to the

page_text: framework a said discharge plate being rotated to the extent of one revolution to
every twenty four revolutions of the hour wheel.
The face of the discharge plate f is marked off into divisions each representing
five minutes or other fractional periods of time and holes are punched or drilled at
any of these divisions or intermediate thereof for the reception of studs or pins fl
whose number and disposition around the discharge wheel are determined by the
periods of time at which the checking or indicating is. required to take place. In
conjunction with the eight day's clockwork I employ the striking mechanism of a
thirty hour's clock consisting of levers g and h for releasing said mechanism, spring
barrel i, fusee j, the train of wheels k, k', k³, k³, "fly" k, and snail mounted on
the shaft k. Connected with the lever g is a short lever arm g¹ which is adapted
to be engaged by the pins f¹ on the discharge wheel as the latter rotates and to
elevate the said lever g which lifts the lever h clear of the snail k whilst the short
lever arm secured on the same stud as the lever is at the same time placed
clear of the pin on the toothed wheel k², whereby the mechanism is temporarily
い
released and is put in motion by the uncoiling of the spring in the barrel i.
The motion of the parts, however, is only temporary so as to bring the larger
diameter of the snail k under the depending leg of lever h and is arrested by the
pin m on wheel k³ engaging a projection n on the end of lever g, but immediately
the pin in engagement with the lever arm g¹ rides clear of said lever arm the
lever g assumes its normal position and releases the wheel and therefore the
striking mechanism whereupon the action of the coiled spring causes the parts to
be rotated until the cam or snail has completed a revolution and is again locked
by the depending foot of lever / as shewn on the drawings.
The parts remain in the positions shewn in Fig. 1 and inoperative until a second
pin on the discharge wheel actuates the lever arm g¹ when they are operated as
previously described and this is repeated each time a pin on the rotating
discharge wheelf engages the lever arm g'.
On the
The intermittent motion obtained as above set forth is for the purpose of rotating
at predetermined periods, the frame or drum o, in which are loosely placed the
boxes p for receiving the workmen's tokens or checks, to the extent of one box so as
to bring another box under the shoot q to receive the checks of workmen arriving
after a given time and before the expiration of the next given period. The means
I employ for transmitting such motion to the frame or drum o consist of a pinion r
mounted on the snail shaft and gearing with the spur wheel k on the fusee j, or
if no fusee be employed a pinion mounted on a stud and gearing with a spur wheel
on the spring barrel i may be substituted for the arrangement shewn.
same shaft is mounted a bevil wheel 1 gearing into a bevil wheels secured on a
short shafts on which is a second bevil wheel gearing with a bevil wheel t
supported by a bracket and having a square ended spindle wbich enters into the
end of and is adapted to rotate a vertical shaft t. At the lower end of the said
vertical shaft but not connected therewith is a pinion t supported in a footstep t³
and engaging with the teeth of the spur wheel o' cast on or attached to the drum o.
The pinion carries a stud or pin which is adapted to enter a corresponding
opening formed in the flange at the base of a hollow sleeve or tube to placed on the
shaft t. The said sleeve is secured to the shaft so as to rotate therewith by means
of a set screw passing through a slot t' in the sleeve, but such sleeve is capable
of being moved up and down the shaft to place it out of or into engagement with
the pin to disconnect the drum or frame o from the operative mechanism or
connect it therewith. When disconnected the drum or frame can be turned round
to examine the contents of all the boxes or to change the order of said boxes or
for other purposes without interfering with the clockwork mechanism.
It will be seen from the above that each time the escapement or striking
mechanism is released by a peg or pin on the discharge wheel and the snail
rotated to the extent of one revolution the pinion t will be likewise rotated to
the extent of one revolution through the medium of bevil wheels r', &, and t and i
shaft and the number of teeth on said pinion being equal to the number of teeth

page_text: between each division of the frame or drum o the last named will be rotated to the
extent of one division and bring the next box p under the shoot 9 into which the
tokens or checks are placed by the workman who introduces them through slots q¹
in the framework or case enclosing the time checking apparatus.
The boxes or divisions of the drum or frame o are marked to accord with the
time at which they are to be brought under the shoot g as indicated at Fig. 5 and
said boxes are removable at will. Each workman or operative is provided with a
check or token numbered or lettered to indicate to whom it belongs, and as the
time at which each box is presented under the shoot is exhibited through an
opening, the particular boxes into which the tokens or checks are deposited
establishes without question the time of arrival or departure of the workmen -and
there is no disputing of the record.
As an illustration of the action of the apparatus I will assume that work
commences at seven o'clock A.M. and that three minutes grace is allowed. The box
marked seven will remain under the shoot q until the minute hand of the clock
indicates three minutes past seven whereupon a pin on the discharge wheel f
will release the escapement or striking mechanism as before fully described and
cause the frame or drum o to be rotated to the extent of one box, moving the box
marked seven from under the shoot and presenting the next box marked at any
required time-say-seven-fifteen in its place. Into this box those coming between
three minutes past seven and eighteen minutes past seven will deposit their checks,
and their time of arrival therefore be recorded as seven-fifteen this being repeated
as many times during the day as may be required, and at any predetermined
time.
The frame or drum o may be constructed to hold any number of boxes p, the
number of teeth between each division, however, always being equal to those on the
pinion. In cases where the number of checks expected to be deposited in one or
other of the boxes exceeds the capacity of said box or boxes an opening p' is made
in the bottom thereof as shewn at Fig. 7 through which the checks pass into a
receptacle underneath the frame o. The drum or frame o is supported by and
rotates upon a ball bearing as shewn at Fig. 1 or on a cone bearing as illustrated
at Fig. 4. Instead of effecting the periodical partial rotation of the drum or
frame o through the medium of the striking mechanism in the manner set forth, I
may establish an electric connection with the lever h, which is insulated from the
other parts and an electro magnet u as illustrated at Fig. 8, the engagement of the
lever g with the lever h completing the circuit and causing a double pallet v to be
attracted by the electro magnet and tilted into the position shewn in dotted lines
which moves the left hand end of said pallet clear of one of the studs v¹ secured
to the underside of the drum or frame and places the opposite end in the path of
the next stud. This allows the drum or frame o to be slightly moved by the
weight and cord by which in this case the drum is rotated, and to place the stud vl
beyond the reach of the left hand end of the pallet so that when the pin on the
discharge wheel passes clear of the lever arm g' and allows the lever g to fall
back to its normal position, the circuit will be broken and the pallet allowed
to resume its normal position, whereby the drum will then be rotated by the
unwinding of the cord off the barrel o² until the next stud engages with the
left hand end of the pallet, the extent of motion being equal to one box In
p.
Fig. 9 a single pallet is shewn which is moved clear of the pegs on the underside
of the drum each time an electric connection is made and returns to its normal
position before the next peg arrives. Flat or spiral springs may be employed to
ensure the return of the pallets to their normal position.
In Fig. 10 I use the pinion t' and toothed frame by which a steadier motion can
be obtained. The frame or drum is rotated as in Figs. 8 and 9 by means of a cord
wound upon a barrel and attached at its free end to a weight.
The pallet or lever in this case normally engages the pin and is drawn clear
thereof by the electro magnet each time an electric connection is made by a pin on
the discharge wheel releasing the escape mechanism. The electric connection-may

page_text: he made with an ordinary turret clock and where the drum or frame is situated at
some distance from the clock or where two or more time checking apparatuses are
in se at different places on the premises the use of an electric connection is
preferable and only one clock is required to actuate them.
Although I have shewn and described the electric connection as being established
by the contact of lever o with lever it may be made by a cam or snail on the
suail or other suitable shaft of the striking mechanism acting on a separate lever,
the connection being made either short or long as required by increasing or reducing
the dwell on the cam.
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
claim is :-
Firstly. In apparatus for checking or indicating the periodical arrival or
departure of employees, a discharge wheel or disc driven from the minute wheel of
the clock and having provision for receiving pins or studs for determining the
actuation of the checking apparatus at desired intervals of time, a lever arm
adapted to be engaged by said pins and to release the parts for transmitting motion.
to a vertical shaft, a pinion adapted to be driven by said shaft and gearing with a
toothed drum or frame which holds the check receiving boxes, all arranged and
operating in the manner and for the purposes substantially as herein shewn and
described.
•
Secondly. In apparatus for checking or indicating the periodical arrival or
departure of workpeople, the combination with an eight day's clock, a discharge
wheel or plate such as f, pins, and lever arm g', of the parts comprising the
striking mechanism, and the gearing for rotating the frame or drum o in the manner
and to the extent substantially as herein set forth.
Thirdly. In apparatus for checking or indicating the arrival or departure of
workpeople, the combination with a drum or frame constructed to hold the check
receiving boxes of the toothed rim or spur wheel o' formed or secured thereon, and
a pinion such as t2 adapted to gear therewith and having the same number of teeth
as there are teeth between each section into which the frame is divided, said parts.
being operated in the manner and for the purposes substantially as shewn and
described.
Fourthly. In workpeople's time checking or indicating apparatuses, a sleeve or
tube such as to secured rotatably to the shaft t¹ but adapted to slide vertically
thereon and to engage with a pin or projection on the pinion t' and to give motion
to said pinion substantially as set forth.
Fifthly. The method and means combined with the discharge plate or disc for
releasing the drum or frame o by electrical connection substantially as herein
described and shewn in Figs. 8, 9, and 10.
Lastly. The general arrangement, combination, and operation of mechanism
comprising the apparatus for checking or indicating at periodical intervals the
arrival or departure of workpeople substantially as described and shewn.
