PROVISIONAL SPECIFICATION.
An Improved Carillon Machine or Apparatus for Performing Tunes
upon Bells.
We, ROBERT POTTS, JAMES POTTS and JOSEPH POTTS, trading as the firm of
William Potts and Sons, of Guildford Street, Leeds, Turret Clock Manufacturers, do
hereby declare the nature of this Invention to be as follows:-
Our invention has reference to certain improvements in apparatus for chiming,
ringing or playing church and other bells.
And our said improvements consist in the employment of cylinders upon shafts
mounted in suitable frames, the said cylinders having a series of V shaped or mitre
grooves around or upon their peripheries. In the said grooves are placed a series of
cams or projections of various heights, according to the amount or depth of tone or
intonation required, or according to the strength of blow to be given to the bells.
The said cams or projections are secured in the aforesaid grooves by bolts having
bevelled or mitre heads to correspond with the section of such grooves.
.
A wire or rod is connected from the hammers or tongues of the bells to levers
arranged upon a suitable shaft in front of the cylinders aforesaid.
The cylinders are revolved by ordinary gear and weights, and as the cams or
projections come in contact with the levers, they depress them, thereby striking the
bells.
By untightening the bolts of the said cams or projections such can be moved in the
grooves to make a change of tune, and can be placed in any position required by the
music, and can be adjusted to any nicety.
Provision is also made for allowing the cams or projections to be easily withdrawn
or put in the grooves aforesaid when such is required.

An Improved Carillon Machine or Apparatus for Performing Tunes
upon Bells.
We, ROBERT POTTS, JAMES POTTS, and JOSEPH POTTS, trading as the firm of
William Potts and Sons, of Guildford Street, Leeds, Turret Clock Manufacturers, 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:
-
Our invention has reference to certain improvements in apparatus for chiming,
ringing or playing church and other bells.
DESCRIPTION OF DRAWINGS.
Fig. 1, is an end elevation of carillon machine with our improvements applied.
Fig. 2, is a detail view of lever and cams.
Fig. 3, is a plan of Fig. 2.
Our said improvements consist in the employment of cylinders A, A, upon
shafts B, B, mounted in a suitable frame C, the said cylinders having a series of
V shaped or mitre grooves D around or upon their peripheries. In the said
grooves D are placed a series of cams or projections E of various heights, according
to the amount of depth of tone or intonation required, or according to the strength of
blow to be given to the bells.

page_text: The said cams or projections are secured in the grooves D by bolts F having bevelled
or mitro heads to correspond with the section of such grooves, and to prevent them
turning in the said grooves D."
A wire or rod G is connected from the hammers H of the bells J to levers K
arranged upon suitable shafts L in front of the cylinders aforesaid. The levers M of
the hammers H are arranged upon centres M', so that when the lovers K are
depressed by the cams or projections E, the wires or rods G pull the ends M2 of the
levers M down correspondingly, thereby bringing the hammer H into the position
shown by the dotted line H¹ ready for striking.
Immediately the cams or projections clear the levers K, the weight or momentum
of the hammers cause them to fall self-actingly and give the necessary blow to the
bells.
"
The cylinders aforesaid are revolved by ordinary gear and weights. In the gearing
shown in Fig. 1, N is the driver carried upon the central shaft N1, N2 and N3 aro the
followers carried upon shafts B, B, for driving the cylinders A, A. O is for
re-winding the weight and rope as it is unwound by the driver or barrel N. P is for
driving the pinion P¹ upon the shaft of which is carried a fly R for regulating the
speed of the cylinders A, A...
By unscrewing the nuts S of the bolts F, the said bolts can be untightened and the
cams or projections E can be moved in the grooves D to make a change of tune, and
can be placed in any position required by the music and can be adjusted to any
nicety.
Provision is made for allowing the cams or projections E to be easily withdrawn or
put in the grooves aforesaid when such is required, by rounding or hollowing out a
certain part of the said grooves as indicated at T.
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 ;-
The employment of cylinders having grooves carrying cams or their equivalents for
operating the levers K substantially as and for the purposes shown and described.
