Improvements in Bells, and in Means for Actuating the same.
I, HARRY MATHER, of 89, Wellington Street, Oakes, Lindley, near Huddersfield,
Yorkshire, Piecer, do hereby declare the nature of this invention to be as follows:-
My invention relates to bells and means for actuating the same.
In carrying out my invention I form on the bell an internally projected transverse
ridge so as to engage suitable rotating knocking arms or hammers loosely pivotted
at the ends of a cross bar, in order that, as the said bar is revolved, the hammers
will strike against the bell and cause it to ring.
The said cross bar is secured to a sleeve which is free to turn on a spindle fastened
at one end to the bell and supports at its outer end a chest fitted with suitable inlet
and outlet pipes. The said sleeve projects into this chest and is provided with a
suitable number of blades so arranged that when steam, compressed air, or fluid
under pressure is admitted into the chest through the inlet pipe, the blades are forced
round, consequently imparting a rotary motion to the cross bar.
In lieu of rotating the said cross bar by means of steam, compressed air, or fluid
as above explained I may use electricity to accomplish this purpose, or if desired
hand power may be employed.
The bell may be used for motor cars, ships, and also as a signal bell for workshops
and the like or for any other purpose where suitable power is available.

Improvements in Bells, and in Means for Actuating the same.
I, HARRY MATHER, of 89, Wellington Street, Oakes, Lindley, near Huddersfield,
Yorkshire, Piecer, 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 bells, and to means for actuating the hammers or clappers
of the same. It consists of a bell or gong having internally disposed flanges or
projecting ribs arranged in its interior near its periphery; and in a sleeve mounted
so as to be capable of being rotated freely upon a spindle disposed concentrically
with the bell. Upon that part of the sleeve which is inside the bell is mounted a
cross bar which has hammers pivoted loosely to its ends, while to the other end of
the sleeve a number of blades are fixed in such manner that an current of steam
or the like causes the blades, sleeve and cross bar to rotate.

Fig. 2 is a front elevation of same.
Fig. 3 is a front elevation of steam chest used, with cover removed.
Fig. 4 is an elevation of the central spindle.
Fig. 5 is a longitudinal section of the sleeve, shewing blades attached.
Fig. 6 is an end elevation of same.
Throughout the drawings like letters indicate similar parts, or parts fulfilling
similar functions.
A indicates the central spindle upon which is mounted a sleeve B in such manner
as to be capable of rotating freely thereon. Fixed rigidly to this sleeve, either
by means of screw threads as shewn, or otherwise, is a cross bar C having forked
ends c to which are loosely pivoted hammers or clappers c¹ by means of pins c² passing
through the arms of the fork and also through the hammers c¹: D indicates the
gong or bell proper which is provided with a central hole to fit one end of the
spindle A, and is fixed thereon by means of nuts or the like. Arranged inside
the bell are a suitable number of flanges or projections d which project
sufficiently far to ensure that when the cross bar is rotated the hammers c¹ shall
come into contact therewith, and thus cause the sound.
:
Surrounding the other end of the spindle A is disposed a box or chest E having a
steam tight cover e provided with a circular hole through which the spindle passes.
The chest E has an outwardly projecting flange e¹ which enables a steam tight joint
to be formed between it and the cover e to which it is screwed as shewn. This
chest is secured to the spindle, which passes through it, by being held between
a flange a formed on the spindle end, and a nut a screwed on to the extreme end
of the spindle; thus serving to hold the steam chest firmly, and at the same time
form a steam-tight joint.
Formed integrally with or rigidly fixed to that portion of the sleeve which is
disposed inside the chest, are a number of blades F projecting in રી
radial or approximately radial direction in such manner that they are
capable of being rotated by means of the impingement of the current
of steam, compressed air, or other fluid entering through the inlet pipe G.
When either of the blades F has made about one third of a rotation the steam or
other fluid is free to escape through the exhaust pipe G¹ into the atmosphere, or
into a receptacle.
.
It will thus be seen that my invention consists of a bell which is rung by rotating
hammers or clappers, which are operated by means of steam, compressed air, or
other fluid impinging upon the blades F. The hammers or clappers in the course
of their rotation striking the flanges or partitions & produces the required sounds.
The bell and mechanism can be conveniently fixed in any required position by
means of a bracket H, and if necessary by means of angle or other shaped pieces h.
In lieu of rotating the cross bar by means of steam, compressed air, or fluid as
above explained, I may use an electric motor to effect this purpose, or if desired
hand power may be employed.
The bell may be used for motor-cars, ships, and also as a signal bell for work-
shops and the like, or for any other purpose where suitable power is available.
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. A bell, the hammers or clappers of which are rotated by means of steam or
other fluid jet so as to strike flanges or projections, in the interior of the bell,
substantially as described and shewn.
2. A bell actuated by steam or other fluid impinging upon blades fixed to the
same rotating sleeve as the hammers or clappers are mounted upon, substantially
as described and shewn.

page_text: 3. A bell or gong having flanges or projections in its interior against which
hammers or clappers strike when they are rotated, substantially as described and
shewn.
4. In a bell sounded by means of rotating hammers or clappers, the combination
of the gong D, the central pin A, the sleeve B, the cross-bar C having hammers or
clappers c, the steam or other fluid pressure chest E, the blades F, and the inlet and.
exhaust pipes G and G¹, substantially as described and shewn.
5. In a bell sounded by means of rotating hammers or clappers, the combination
of the gong D the central pin A, the sleeve B, the cross bar C, having hammers or
clappers e, the steam or other fluid pressure chest E, the blades F, the inlet and
exhaust pipes G and G, the brackets H and angle or other shaped pieces h,
substantially as described and shewn.
6. In a bell sounded by means of rotating hammers or clappers the combination
of the gong D, the central pin A, the sleeve B, the cross bar C having hammers or
clappers e¹ and an electric motor, substantially as described.
