Improvements relating to Workman's Time Checking and Recording
Machines.
I, ALFRED GRIFFITHS, of 62, Stanley Grove, Longsight, Manchester, in the
County of Lancaster, Watchmaker, do hereby declare the nature of this invention
to be as follows:-
-
This invention relates to all classes of machines where motion is required to
be communicated at definite interrupted periods and particularly to that class of
workman's time checking and recording machines wherein the workman has to
sign his name or impress his number on a continuous strip of paper and in some
cases by the additional pulling over of a handle or lever which causes the exact
time or period within which such signature is made or number impressed to be
printed close to the said signature or number and the object of this invention is
to construct a mechanical apparatus which shall change or alter the type of such
checking and recording machine once in any given period as for instance once
every minute, so that the machine will always be in a condition to print the exact
time or the period within which such signature is made or number impressed.
For the purposes of my invention I attach to an ordinary clock a train of wheels
driven by the same device which moves the wheels of the clock, and attached to
any suitable wheel of the clock so as to be regulated thereby. The regulation is
effected by the lifting of a lever which receives its action from a ratchet wheel
which the action of the lever allows to travel round one tooth space for every
equivalent movement of the wheel of the clock from which its action is derived,
as for instance one tooth per minute. Upon this lever there is an arm which lifts
a catch out of a notch in the edge of a disc which at once releases the fly and sets
the train in motion.
The disc may have any suitable number of notches and is fixed on the wheel
that drives the fly. Every lift of the lever allows this wheel to turn the fly the
required number of times. The disc wheel is driven by a wheel which has fixed
on its shaft a pin wheel having any desired number of teeth as for instance 52
which gives motion to a lever, which lever is attached to the type printing
apparatus and by its motion gives the necessary pull or lift to change the type
from time to time as for instance minute by minute.

Improvements relating to Workman's Time Checking and Recording
Machines.
I, ALFRED GRIFFITHS, of 62, Stanley Grove, Longsight, Manchester, in the
County of Lancaster, 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 relates to all classes of time checking and recording machines
wherein motion is required to be communicated at definite interrupted periods,
and particularly to that class of workman's time checking and recording machines
wherein the workman has to sign his name or impress his number on a continuous
strip of paper and in some cases by the additional pulling over of a handle or lever
which causes the exact time or period within which such signature is made or
number impressed to be printed close to the said signature or number and the
object of this invention is to construct a mechanical apparatus which shall change
or alter the type of such checking and recording machine once in any given period
as for instance once every minute, so that the machine will always be in a con-
dition to print the exact time or the period within which such signature is made
or number impressed.
The manner in which my said invention is to be performed or carried into
practical effect will be readily understood on reference to the sheet of drawings
hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a partial sectional elevation and Fig. 2 a side view of
the works of an ordinary eight day clock with my invention shown as applied
thereto.
a is a portion of the frame and b is the ordinary train of wheels.
For the purposes of my invention I provide the clock with a secondary train
of wheels c.
This train of wheels c is actuated by a spring barrel d and it is connected to
and regulated by the ordinary train 6 of the clock in the following manner.
Upon the arbore of the centre wheel of the clock which carries the hands (see
Fig. 1) I mount a ratchet wheel of having (say) sixty teeth in gear with which is
a short ratchet or lever g to which is attached a long lever h curved into a hook
at the end, which alternately holds and releases an arm i fixed on the spindle k
which carries the "fly" as the levers g and are caused to rise and fall by the
action of the teeth of the ratchet wheel f. The holding position of the lever his
shown by the full lines at Fig. 1 and the releasing position in dotted lines.
Whenever the fall of the lever h releases the "fly" the train of wheels c is put
in action by the spring d.
On the arbor of the wheel c* of this train is fixed a wheel or disc m having (say)
four teeth above which hangs a catch n which is held up or allowed to fall onto
the notched disc m by a lever o a pin at the end of which rests on the lever h so
that they rise and fall together, the effect of which is that when the "fly" is re-
leased the wheel c* can only make (say) one fourth of a revolution that is to say
the length of one tooth on the disc m which the catch then holds fast until again
released.
The disc m may have any suitable number of notches and is fixed on the arbor
of the wheel c which drives the "fly" so that every lift of the lever h allows
this wheel to turn the "fly" the required number of times. On the arbor of
the wheel which drives the wheel e is fixed a pin wheel having any desired

page_text: number of teeth (as for instance fifty two) which gives motion to a lever q on a
shaft g, a lever r on the end of which is connected by a rod to the type printing
apparatus of the checking machine, and by its motion gives the necessary pull or
lift to change the type from time to time as for instance minute by minute as may
be desired.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
The combination with the works of an ordinary eight day or other clock and
with a workman's time checking and recording machine of the class above speci-
fied of an additional train of wheels provided with a "fly" driven by a spring or
weight the action of which is controlled by a ratchet wheel fixed on the arbor of
the centre wheel of the ordinary clockwork. (or upon any other suitable arbor!
which as each tooth of such ratchet wheel lifts a catch, it releases the "flv" and
allows the additional train of wheels to be put in action until a catch falls and
holds the same fast, and a pin wheel fixed on the arbor of one of the wheels of the
said train which acts upon a lever (say) once in every minute which lever is con-
nected by a rod to the type box of the checking and recording machine.
