Improvements in or connected with Olocks.
We, FRED LAYCOCK, of 46, Bradford Road, Jeweller, and PRIESTLY ATKINSON
BENTLEY, of the Commercial Hotel, Bradford Road, Hotel Keeper, both in Cleck-
heaton in the County of York, do hereby declare the nature of this invention,
and in what manner the same 18 to be performed, to be particularly described and
ascertained in and by the following statement:
This invention relates to improvements in or connected with clocks, and 18
more particularly applicable to clocks employed in the regulation of games of
billiards and other suitable games, where a time limit is fixed in which persons
shall have the use of a billiard table, or the like, for instance, say a person wishes
to have the use of a billiard table for twenty minutes, by our improvements
immediately the twenty minutes has expired, such expiration is automatically
indicated by the stroke of a hammer upon a gong, further the periods more or
less may be regulated as desired
DESCRIPTION OF DRAWINGS.
Fig 118 a back view of the frame and works of an oidmary clock, with our
improvements applied
Fig. 2 18 a side view of Fig 1
Fig. 3 is an enlarged detail showing the regulating and setting mechanısın
for indicating periods of time
We preferably extend the centre ai boi A at the back of the clock, and fix a
boss or washer B to the side of the frame C, mounted and loose upon the ex-
tended centie arbor is a suitable disc D, a number of pins or studs E pass through
and project from both sides of the disc at regular intervals, for instance, if it is
requied to give an alarm every twenty minutes, three pins are employed see
Figs 1 and 2, if an alarm is required every fifteen minutes, four pins are used,
if every five minutes, twelve pins are used, each pin representing an alarm to be
given within the hour
The aforesaid disc D is provided with a boss E³, having a conical recess E',
also upon the centre arbor is a suitable nut F having a neck FI, and conical or
taper end G which fits or bears against the conical recess E' in the boss of the disc
this nut has a key H provided, which slides within a keyway J in the centre
arbor A, the pressure of the spring upon the nut F creating sufficient friction
of the conical end within the coresponding recess in the boss of the disc, as to
cause the said disc to revolve with the nut when motion is imparted to the centre
arbor.
Within the neck of the nut F is the fork L of a pivotted lever M, pivotted
at M' upon the clock-fiame C, this lever M 18 operated when desired by a vertical.
lever N pivotted at N¹, and connected by a spring sliding rod P, to a push
button R projecting beyond the face of the clock preferably near its outer edge.
We also provide a lever or bar S, hinged or pivotted at St, which bears against
and is operated upon by the pins E, this bar actuates the said disc D at the
expiration of each period in such a manner as to release the hammer, which strikes
the gong, giving the alarm, and bring the said disc into position for commencing

page_text: a further period of time, such action of the said bar or lever 18 effected by means
of spring T
According to our improvements as shown at Figs. 1 and 2, the clock is arranged
to give an alarm every twenty minutes, and the action is as follows;-
-
The disc Dievolves in the direction indicated by allows, by the means before
described, and at the same ratio of speed as the clock hands, the pin E on the
1ight comes in contact with the cycle shaped wire U (which 18 connected with
the wire V of the hammer W) raising same and tilting the hammer W back-
wards tightening the spring X, while this movement is taking place, the pin
to the left upon the opposite side of the disc is depressing the sping bar or
lever S.
When the pin upon the left arrives at the position previously occupied by the
pin on the right, the latter will have taken up the position of the third pin above,
and in doing so simultaneously moves out of contact with the wue U so releasing
the hammer which strikes the gong and gives the alarm, this action takes place
every twenty minutes
When only part of the term has expired and it is desired to set the clock to
give an alarm in twenty minutes, the push button R is operated, which in turn
actuates the vertical pivotted lever N, connected to the forked lever M, this lever
inoves the conical end G of the nut F out of contact with the disc D, this disc
(being loose upon the centre ai bor, and by the pressure of the aforesaid lever S
upon the left hand pin) is brought back to its original position, shown at Fig 1
and ready for commencing another teim
By these improvements the length of games may be regulated and notified
without possible error
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
1 In clocks, the use and employment of a disc D having a number of pins E,
acting upon the cycle U of the sping hammer W, and operated in the manner
and for the purposes set forth
2. In clocke, the use and emplovment of a disc 1 upon the centre aibor A,
having a number of pins E projecting from both sides, and cycle U, in combina-
tion with the levers S, M, N, P, and button R operating in the manner and for
the purposes, substantially as shown and described
3 In clocks, the use and employment of a nut F having a sliding key H, and
a conical end G, fitting within a conical recess D, in the boss E of disc D and
sping K, in combination with the forked lever M, for disengaging and engaging
the disc in the manner and for the purposes, such as shown and described
