Improvements in and connected with the Chiming Apparatus of
Turret Clocks and the like.
We, ROBERT POTTS, JAMES POTTS, and JOSEPH POTTS, trading as the firm
of William Potts and Sons, of Guildford Street, Leeds, Turret Clock Manu-
facturers, do hereby declare the nature of this invention, and in what manner the
ned in and by the

DESCRIPTION OF DRAWINGS.
Fig. 1, is a sectional elevation of our invention.
Fig. 2, is a plan.
Fig. 3, is an end elevation.
Fig. 4, is a section showing how the parts are secured together.
According to our improvements the great wheel A. of the striking part of a
turret clock or similar mechanism (which is carried upon a shaft B mounted in a
frame C) has secured to it by bolts D a cylinder E having grooves F around its
periphery in which are placed cams or tappets G secured in the said grooves by
bolts H and nuts J by which the positions of the cams or tappets can be fixed,
altered, or adjusted to any nicety in the said grooves (as required by the music or
tune) by screwing or unscrewing the nuts J; when unscrewed the cams or tappets.
can be slid or moved in the said grooves.
Wires or rods K are connected from the hammers of the bells to levers L
secured upon a shaft M carried upon brackets N fixed to the frame C. The cams.
or tappets G in revolving along with the great wheel A actuate the levers L by
depressing them, thereby pulling down the wires or rods K which cause the
hammers of the bells to be lifted from out of contact with the bells; on the cams.
or tappets clearing the levers the weight of the hammers of the bells causes them
to fall self-acting and give the necessary blow to the bell. O is the drum on
which the clock weight cord is wound to give motion to the train of wheels.
The number of cams and tappets and levers is determined by the music selected
to be played and by the number of bells provided.
By attaching the cams or tappets in the manner set forth occasional adjustments.
that are needed to take up the wear and tear of the cams or levers can be much
more quickly and accurately made than when other methods are adopted, in
addition to greatly facilitating the change of tunes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
In chiming apparatus for turret clocks and the like, the combination with the
great wheel of such turret clock or the like of a cylinder having grooves carrying
cams or tappets (capable of being moved as required in the said grooves) which
in revolving along with the said great wheel actuate levers connected with
wires or rods communicating with the hammers of the bells, substantially as and.
for the purposes shown and described.
