PROVISIONAL SPECIFICATION.
Improvements Appertaining to Mechanism for Recording or Checking
the Time of Entrance of Employees into Workshops or the like.
I, ARTHUR DENBY SMITH, Managing Director of The Keighley Electrical
Engineering Company Limited, of Keighley in the County of York, Electrical
Engineers, do hereby declare the nature of this invention to be as follows, that is
to say
It relates to mechanism for recording or checking the time of entrance of employees
into workshops or the like and consists of constructing the clockwork of said
mechanism and parts in connection with it so that same may be readily prearranged
or readjusted to meet the requirements of the varied times at which it is or may be
required to perform its functions.
To attain tbis object a supplementary dial of electrically insulating material is
mounted preferably at the rear of the clock-work.
In or on this dial are mounted, according to one arrangement, two rings or annular
pieces of metal concentrically with the dial through which latter and into each of the
former are made a series of holes for the insertion and reception of screws or peg
these said holes being made to correspond with the time indicating marks on the dial
either for every quarter hour, five minutes or more or less as may be thought desirable
or necessary. These rings are the terminals of a battery in the circuit of which are
mounted two electro magnets insulated from each other for operating or controlling
the movements of the time checking mechanism, the electric circuit of one magnet
being completed through one ring and the metallic parts of the clock and that of the
other magnet through the other ring and the same parts of said clock..
A contact handle is made to move over the face of this supplementary dial either
at the rate of speed of the clock's hour or minute hand or faster or slower as required
by which means as it comes in contact with small metallic pieces electrically connected
to one or other of the annular pieces on the dial by or through its holding screw or
peg the circuit in which one of the electro magnets is placed will be completed in
order to release or prepare certain of the checking mechanism's operating parts, be
they for the moving of a rotary or other style or kind of shoot or hopper or the
moving of the receptacles for the workinen's time checks or otherwise so that as such
handle proceeds in its course to come in contact with the next contact piece said
movement will be allowed to be performed by the circuit, in which, the other electro
magnet is situated, being completed. And as these contact pieces may be as numerous
as desired or since they may be arranged or fixed in any of the varied positions on
the dial, the time of exercising the clock's controlment over the mechanism above
described may be prearranged to take place at any time.
Instead of the electric circuit being completed through the metallic parts of the
clockwork the handles of the clock may be arranged to be in contact with an annular
conducting piece forming one of the terminals of the battery.
Again another annular piece formed so that the hour handle of the clock may only
periodically come into contact with it may be employed by which means the minute hand
of said clock although coming in contact with the varied contact pieces in its path_of
motion does so ineffectually until the hour hand comes into contact with the annular
piece last before described, or an arrangement of handles other than these usually
styled or corresponding to the hour and minutes handles of the clock may be employed
as will readily be understood.
In addition to the above described parts another annular piece may be mounted on

page_text: the supplementary dial so that contact pieces for the handles of the clock may be
arranged to enable said handles to complete the circuit through an electric bell or
other alarm by which means indications of the movements of the checking apparatus
may be transmitted to distance, or signals given for any other purposes desired.

Improvements Appertaining to Mechanism for Recording or Checking
the Time of Entrance of Employees into Workshops or the like.
I, ARTHUR DENBY SMITH, Managing Director of The Keighley Electrical
Engineering Company Limited of Keighley in the County of York, Electrical
Engineers, 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, that is to say :-
It relates to mechanism for recording or checking the time of entrance of employees
into workshops or the like and consists of constructing the clockwork of said mechanism
and parts in connection with it so that same may be readily prearranged or readjusted
to meet the requirements of the varied times at which it is or may be required to
perform its functions.
In the accompanying sheets of drawings
Fig. 1 is back elevation of clockwork and mechanism for receiving the tokens or
checks of employees, to which my improved parts are applied.
Fig. 2 is a similar elevation but illustrates drum mechanism for receiving a chart or
paper on which the workmen may write their names or otherwise affix their distinctive
marks instead of the said token-receiving-mechanism.
Fig. 3 illustrates a dial as seen mounted at the back of the clock and as arranged
in accordance with my invention.
Fig. 4 is a view of the opposite side of said dial to that shown by Fig. 3.
Figs. 5 and 6 are similar views to Fig. 3 but illustrate modifications hereinafter
described.
Fig. 7 is a drawing in detail showing an alternative method of arranging certain
of the parts.
Similar letters and figures of reference indicate similar parts throughout the
several views.
To attain the object of my invention a supplementary dial a of electrically
insulating material is mounted preferably at the rear of the clockwork.
In or on this dial a are mounted according to one arrangement, two rings or
annular pieces bc of metal concentrically with said dial a through which latter and
into each of the former are made a series of holes f for the insertion and reception
of screws or pegs g. These said holes are made to correspond with the time
indicating marks on the dial or front face of the clock, either for every quarter hour,
five minutes or a greater or a less length of time as may be thought desirable or
necessary, those in the several drawings being arranged to indicate for every quarter
of an hour.
These rings b c are the terminals of a battery in the circuit of which are
mounted two electro magnets hk insulated from each other for operating or
controlling the movements of the time checking mechanism as that at m in Fig. 1
or that at n Fig. 2, the electric circuit of one magnet h or k being completed through

page_text: one ring bor c and the metallic parts of the clock, and that of the other magnet
through the other ring and the same parts of the clock.
A contact handle p is made to move over the face of the dial a either at the
rate of speed of the clock's hour or minute hand, in which case it is mounted on
the same spindle gq as are said hour and minute hands, which for this purpose is
extended beyond the ordinary clockwork bearings and out at the back, or such
handle p may be made to move faster or slower than is said ordinary hour or
minute hand, this being effected by the additional spindler (see Fig. 7) which is
arranged to receive its motion from any suitable motor parts of the clock, while
by the gearing wheels (which are of such dimensions as to secure the desired
results as to rate of speed) it transmits motion to the handle p as required, by
which means as said handle p revolves and comes into contact with the small
metallic pieces s electrically connected to the rings bc by or through their holding
screws or pegs 9, upon which rings b and c they are arranged to occupy alternate
positions, the circuits in which the magnets h and k are placed will be alternitely
completed in order to release or prepare certain of the checking mechanism's
operating parts (which may be any of the well known kind but which are herein
shown as being the two levers operated by the magnetsk respectively in
which case the said levers a hold the series of receptacles from being rotated
by the pull of their retracting weight or spring, by lying in the path of motion
of projecting pieces extending from the series of rotary receptacles t, the
arrangement of these pieces t' being such that when one is in contact with or
being held by one lever say the lever c, on this lever being withdrawn by its
magnet h, the series of rotary receptacles t will move until another projecting
therefrom comes into contact with the other lever and such movement is
regulated or adjusted to be equal to the space occupied by each respective division
or receptacle in. the series of receptacles thus they are brought successively into
position opposite the shoot as is required, or in place of the rotary receptacles t,
rotary or other kinds of hoppers or shoots may be employed, or again instead of
either of these a rotary drum vas shown by Fig. 2 may be used as is well under-
stood) so that as such handle p thus proceeds in its course to come into contact
with the series of contact pieces s arranged around the dial a, any movement or action
through which the receptacles t (or other devices above referred to) may be desired
to be taken or controlled during or throughout the entire revolution of the said
handle p may be easily prearranged.
As the contact pieces s may be as numerous as desired or since they may be
arranged or fixed in any of the varied positions in the holes f on the dial a, the
time of exercising the clock's controlment over the mechanism above described
may be prearranged to take place at any time. Although the several divisions on
the dial a are illustrated and described as being arranged to operate at intervals
of a quarter of an hour, it will readily be seen that by turning the contact pieces s
to one side or to the other from the direct radial line in which its respective
holding screw 9 is situated, such division may be enlarged or diminished (without
detaching any part) so as to be made to operate at any greater or less interval.
than that stated.
Instead of the electric circuit being completed through the metallic parts of the
clockwork, the handle p' may be arranged to be in contact with an annular conducting
piece u forming one of the terminals of the battery.
Again another annular piece wo (still mounted on the supplementary dial a) formed
so that said handle p¹ (which in this case may be mounted upon so as to rotate with
the spindle of the clock's ordinary hour hand-or if desired the rate of speed of this
handle p may be varied by gearing as shown by Fig. 7 but for the sake of clearness
I describe it as rotating with the hour hand) may only periodically come into contact
with it, as when moving over the parts w, may be employed, by which means the
handle p (which is here taken as revolving with the clock's ordinary minute hand,
but which by additional gearing may be rotated at any other desired rate of speed in
a similar manner to the variation in the driving of the handle p' above referred to)

page_text: although coming in contact with the varied contact pieces s in its path of motion,
does so ineffectually until the hand p¹ comes into contact with one or other of the
parts to of its annular contact piece w.
From the foregoing description it will be seen that instead of mounting the several
contact pieces s on a supplementary dial a the ordinary dial or clock face may be
electrically insulated and used for this purpose-in which case the ordinary hour and
ininute hands would be used instead of the handles p p', however as the mounting of
the numerous contact pieces upon said dial or face would disfigure it and make it
difficult to distinguish the ordinary indications of the time hands of. the clock, I
preferably use the additional dial described.
In addition to the above described contact pieces another annular piece may be
mounted on the dial a so that contact pieces for the handles p p may be arranged to
enable said handles to complete the circuit through an electric bell or other alarm by
which means indications of the movements of the checking apparatus may be
transmitted to a distance, or signals given for any other purposes desired.
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 :-
1. In time checking or recording mechanism of the class described, contact pieces
formed so that they may be mounted upon an insulated dial substantially as herein
specified.
2. In time checking or recording mechanism of the class described, an insulated
dial, annular conducting pieces mounted on said dial and contact pieces secured
to said annular pieces the same being arranged in combination substantially as
specified.
3. In time checking or recording mechanism, an insulated dial, annular pieces
mounted on said dial formed to receive a series of contact pieces, and an additional
annular piece to complete the electric circuit without requiring the current to pass through
the metallic parts of the clock work, the same being arranged in combination
substantially as herein specified.
4. In time checking or recording mechanism an insulated dial, annular pieces on
said dial formed to receive a series of contact pieces, and an additional annular piece
formed so that the electric circuit may be periodically completed through it, the same
being arranged in combination substantially as specified.
5. The improved mechanism for controlling the movements of workmen's time
recording or checking apparatus substantially as herein set forth.
