Improvements in Bells.
1, PAUL SCHILLING, of Mehlis, Thüringia, Germany, Manufacturer of
Iron and Steel Goods, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a five-stroke bell-that is to say, a bell which, when the
thumb-lever is moved to one side, strikes three times, and on the returu movement
of the thumb-lever is caused by a spring-arrangement to strike twice against the
dome of the bell.
The accompanying drawings, illustrate a bell according to this invention,
Fig. 1 being a longitudinal section thereof, and
Fig. 2 showing the mechanism in plan.
The
The thumb-lever a is mounted on a pin or stud b, and has formed on it, behind
the said pin, an extension c, which has an opening d of peculiar form.
opening d is provided on its inner edge with two teeth e and f, and on its outer edge
with a tooth g.
The striker is formed with two striking-arms h¹ and 2 and also carries, within
the opening d, a pinion or equivalent (hereinafter referred to as a disc) provided
with two tooth-spaces k and l. A spring m serves to pull the thumb-lever a into
the position shown in Fig. 2. The striker is mounted on a pin or screw-stud n,
and its arrangement is such that its striking arms h' and 2 will, when in their most
extended positions, strike against the dome o of the bell, which is carried by a post >>
and is fixed thereon by means of a nut q. r is a clip of any suitable form.
When the thumb-lever a is moved in the direction of the arrow I in Fig. 2, first
the striker his rotated by the tooth e in such a manner that its arm strikes
against the dome of the bell. On further rotating the thumb-lever a in the
direction of the arrow I, the toothy engages in the tooth-space and thereby
rotates the striker h so as to cause the arm 2 to strike the dome o. Finally, the
tooth engages in the tooth-space k, and again throws the arm h' against the dome o.
In the return movement of the thumb-lever a in the direction of the arrow II,
which is caused by the spring m, first the tooth y turns the striker backwards and
thereby causes the arm to strike again against the dome; and then the tooth e
engages in the tooth-space k, and causes the arm to strike against the dome of
the bell.
One advantage possessed by this arrangement is that the principal parts,
including the thumb-lever a, the striker h, and the support s, can be made of stainped
metal.

1, PAUL SCHILLING, of Mehlis, Thüringia, Germany,, Manufacturer of Iron
and Steel Goods,. 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 a five-stroke bell-that is to say, a bell which, when the
thumb-lever is moved to one side, strikes three times, and on the return movement
of the thumb-lever, is caused by a spring arrangement to strike twice against the
dome of the bell.
The drawings filed with my Provisional Specification illustrate a bell according
to this invention,
Fig. 1 being a longitudinal section thereof,, and
Fig. 2 showing the mechanism in plan.
C
The thumb-lever a.is mounted on a pin or stud 6 carried by the base or support s
and has formed on it behind the said pin, an extension in which is an opening dof
peculiar form. This opening is provided on its inner edge with two teeth e and f
and on its outer edge with a tooth g.
The striker his formed with two striking-arms and 2, and carries, within
the opening d, a disc pinion or equivalent (hereinafter referred to as a dise)
provided with two tooth-spaces k and . A spring m serves to pull the thumb-
lever a into the position shown in Fig. 2. The striker his mounted on a pin or
screw-stud n, aud its arrangement is such that each of its striking arms and will,
when in its most extended or outward position strike against the dome o of the bell,
which is carried by a post pand is fixed thereon by means of a nut 7. r is a clip of
any suitable form.
When the thumb-lever a is moved in the direction of the arrow I in Fig. 2, the
striker his first partly rotated by the tooth e in such a manner that its arm ¹
strikes against the dome of the bell. On further rotating the thumb-lever a in the
direction of the arrow I, the tooth y engages in the tooth-space and thereby partly
rotates the striker so as to cause the arm h' to strike the dome o. Finally, the
tooth engages in the tooth-space k, and again throws the arm against the
dome o. In the return movement of the thumb-lever a in the direction of
the arrow II, which is caused by the spring m, the tooth g first turns the striker
backwards and thereby causes the arm to strike again against the dome and then
the tooth e engages in the tooth-space k, and causes the arm.' to strike against the
dome of the bell. An advantage possessed by the construction and arrangement
described is that the principal parts, including the thumb-lever a, the striker h, and
the supports, can be made of stamped metal.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what
elaim is :―
1. A five-stroke bell constructed with a thumb-lever a having an extension c
formed with an opening d the inner edge of which is provided with teeth e/
and the outer edge with a tooth g, and a striker h having a disc or pinion i
formed with tooth-spaces k and to engage said teeth, substantially as herein
described.

page_text: 2. A bell of the kind specified in Claim 1, having a thumb-lever a, striker h, and
dome-carriers, made of stamped metal.
3. The improved bell constructed and operating as described and shown.
2. A bell of the kind specified in Claim 1, having a thumb-lever a, striker h, and
dome-carriers, made of stamped metal.
3. The improved bell constructed and operating as described and shown.
