Improvements in Bells for Use on Velocipedes, and for other
⚫ purposes.
I, ALBERT BOYD HUNN, of 32 Summer Street, in the Town of Bristol,
County of Hartford and State of Connecticut, United States of America,
Machinist and Tool Maker, do hereby declare the nature of this invention to be
as follows:-
The
The primary object of my invention is to provide a gong bell which comes under
the head of what has come to be known as a "double stroke" bell.
desirability of such a bell, especially for bicycles, the essentials requisite to
successful use, and the necessities in its construction have been fully appreciated
by manufacturers, dealers, and users, but bells which have heretofore been con-
structed for this purpose have failed in some important particulars either of cost,
perfection in working, simplicity of construction, ease in adjustment, freedom from
rattling, or convenience in use. My invention is designed to avoid these defects
and meet the necessities which present themselves for bells of this class. In the
construction of "double stroke "bells the following necessities present themselves:
first, the maintenance of the striker normally out of contact with the gong so as
not to check the vibrations thereof except when a blow is struck; second, the
impingement of the striker sharply against the gong at one side to sound the same
and its immediate recoil; third, the sharp impingement, reciprocally, of the
striker against the gong on the other side and its immediate recoil.
Referring to the accompanying drawing, and to the letters and figures marked
thereon, forming a part of this specification, the same letters designating the same
parts or features wherever they occur,
Figure 1 is a perspective view of the bell attached to the handle-bar of a
bicycle (in outline) with the gong broken away so as to show the arrangement of
parts.
Figure 2 is a plan view of the bell with the gong removed as viewed from
above.
Figure 3 is a detailed plan view of the lever and springs, the striker-mount
being shown by dotted lines.
Figure 4 is a vertical sectional view of the striker-mount without the striker.
Figure 5 is a view from below of the striker-mount showing the attachment of
the spring to the striker-mount and central stud.
Figure 6 is a view from above of the striker and
Figure 7 is a sectional view of the striker mounted on the striker arm.
a designates the base-piece which may be provided with any one of the usual
means of attachment to the handle-bar of the bicycle or other support. b is the
gong, also of any usual desired form, size, material, and construction. A post c fixed
preferably in the centre of the base supports the gong, which may be secured
thereto by a screw thread thereon or by any other suitable means. d is a lever
pivoted to the base-piece as at e. This point is preferably located as near as
possible to the circumference of the gong both for convenience of manufacture
and for obvious advantages in use. A spiral spring f holds the lever in position,
being attached to the lever inside the pivot e at g at one end and at the other to a
stud fixed to the base-piece at g¹. The drawing shows the spring f attached to

page_text: the lever by passing its bent end through an aperture therein. Often the attach-
ment is made by passing the bent end over a pin or stud fixed to the lever at the
same point. The particular method of attachment is immaterial. The end of the
lever is forked into two prongs d', d². As herein shown the lever is limited in
motion by its side striking the central post e in one direction and in the other by
the projection d³ which strikes also against the central post c when pressure is
exerted upon the lever. The lever, may, however, be constructed with two prongs,
beginning back of the central post, when the prongs will limit the motion of the
lever. So also if a curved standard, or any other means be employed to support
the gong, a pin placed in the same, or any other suitable place, may be used to
limit the motion of the lever. At its outer end in the construction which I here
show the lever is formed into the familiar finger piece of a bicycle bell at d.
Means (not shown) however, for attaching the end of a rope or wire connecting
with a bell pull or push button may take the place of this finger piece, or any
means may be used to oscillate the lever so as to cause it to perform its function,
that is, to propel the striker-mount from one side to the other. At a point a little
to one side of a line drawn through the pivot e and post c and near the edge of the
base-plate is fixed a post / provided at its upper extremity with a head. This
post h serves as a support and a pivot for the striker-mount, which is preferably,
but not necessarily, cast in one piece and consists of the hub m from the upper
end of which extends the crank or arm l. At the inner end of the arm la pin
is fixed to the crank which supports the striker k. The striker is a lengthened oval
as shown, although it may be diamond shaped or any other form to permit its
construction with two ends k² and a longitudinal slot y which fits loosely over
the pin
c. The crank may be constructed with a shoulder adjacent to the striker
or any similar means may be employed to hold the striker in a position substantially
at right angles to the crank as it moves back and forth like a shuttle as shown
at w in Figure 7.
A small pin n is attached to the striker-arm just back of the striker and projects
from its under side. Carried by this pin are two rolls o and p. The smaller roll o
is the lower in position on the pin and is grooved around its circumference, or so
constructed that the end of a small wire spring may be conveniently coiled around
it and engage it securely. r is a small wire spring bent into a substantially semi-
circular form and coiled loosely around the central post at one end and attached
securely to the small roll o at the other. The prongs d¹ d2 bear against the roll p
in operating the bell. A small vulcanized fibre washers and small spring coiled
around the pin & may be used in a familiar manner to hold the striker in place and
prevent noise and rattling in operation.
The operation is as follows: The spiral spring f holds the lever to the side of
the gong to which the spring is attached. By pressure upon the finger-piece, the
prong d acting upon the roll p moves the striker mount against the force of the
spring away from that side. It will be observed that the construction and
arrangement is such that the spring acts to throw the striker-mount in both
directions and that there is a centre of equilibrium, as I call it, where the striker-
mount is at rest. The prong bearing against the roll p moves the striker-mount
up to this centre where it is at rest, and the spring acts in neither direction. The
merest touch moving the mount in either direction brings it under the influence of
the spring r which drives the striker-mount sharply toward the opposite side of the
gong. The roll p impinges against the opposite prong d2 and the motion of the
mount is checked suddenly. The momentum carries the striker sharply against
the gong. The longitudinal slot permits this motion, and after impingement the
striker will instantly recoil or rebound. The slight friction caused by the washer s
and spring t will hold the striker away from the gong. Upon release of pressure
upon the finger-piece the striker-mount will be driven in the opposite direction by
the prong d² which is actuated by the spring f when an impingement of the striker
will cause a second stroke or sounding of the bell in the same manner as just
described.

page_text: I wish to point out that although designed primarily as a double-stroke bell, this
construction supplies with small variations a bell adapted to any use required
of a bell; by removing the spring fit becomes a single-stroke bell. By rapid
manipulation of the lever it becomes an electric stroke bell. By varying the
form of attachment it may be used as a door bell or a call bell and may be located
near to or far from the place of manipulation.
I have attempted to describe minutely one form of embodiment of my invention,
but I wish it to be understood that I do not limit myself to the exact form of
construction set forth, which it is plain may be varied in many of its details
without departing from the spirit of my invention. In my invention the need of
adjustment is done away with and the same striker-mount can be used in sub-
stantially any size of a bell. The lever need not be of resilient metal and the
parts are made and assembled cheaply, without trial or adjustment, and with
certainty of result assured. The essence of my invention rests in the adaptation
of the peculiar striker to the striker-mount, making possible the use of a non-
resilient lever. I do not, however, confine myself to the exact form of striker or
slot. It is apparent that, while the form shown may be the most effective, the form
of striker and slot may be varied and yet produce substantially the same result.
For example, the striker and slot, either or both, might be round. Or a solid
striker might be arranged with a shank which would move in a slot. I consider
that any construction of a striker so arranged on a striker-mount of substantially
the character described as to permit longitudinal motion to be within the spirit of
my invention.
Improvements in Bells for Use on Velocipedes, and for other
purposes.
I, ALBERT BOYD HUNN, of 32 Summer Street, in the Town of Bristol,
County of Hartford, and State of Connecticut, United States of America,
Machinist, 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 :-
The primary object of my invention is to provide a gong-bell which comes under
the head of what has come to be known as a "double-stroke" bell. The
desirability of such a bell, especially for bicycles, the essentials requisite to
successful use, and the necessities in its construction have been fully appreciated
by manufacturers, dealers, and users, but bells which have heretofore been con-
structed for this purpose have failed in some important particulars, either of cost,
perfection in working, simplicity of construction, ease in adjustment, freedom from
rattling, or convenience in use. My invention is designed to avoid these defects
and meet the necessities which present themselves for bells of this class. In the
construction of "double-stroke" bells the following necessities present themselves:
first, the maintenance of the striker normally out of position with the gong so as
not to check the vibrations thereof except when a blow is struck; second, the
impingement of the striker sharply against the gong at one side to sound the same
and its immediate recoil; third, the sharp impingement, reciprocally, of the striker
against the gong on the other side and its immediate recoil.
Reference is to be had to the drawings, left with my Provisional Specification,

page_text: and to the letters and figures marked thereon, the same letters designating the
same parts or features wherever they occur.
Referring to the drawings:
Figure 1 is a perspective view of the bell attached to the handle-bar of a bicycle
(in outline) with the gong broken away so as to show the arrangement of parts.
Figure 2 is a plan view of the bell with gong removed as viewed from above.
Figure 3 is a detailed plan view of the lever and springs, the striker-mount
being shown by dotted lines.
Figure 4 is a vertical sectional view of the striker-mount without the striker.
Figure 5 is a view from below of the striker-mount showing the attachment of
the spring to the striker-mount and central stud.
Figure 6 is a view from above of the striker.
Figure 7 is a sectional view of the striker mounted on the striker-arm.
In the accompanying drawings the letter a designates the base-piece, which may
be provided with any one of the usual means of attachment to the handle-bar of
the bicycle or other support. b is the gong, also of any usual desired form, size,
material, and construction. A post c fixed preferably in the center of the base supports
the gong, which may be secured thereto by a screw thread thereon or by any other
.suitable means. d is a lever pivoted to the base-piece as at e. This point is preferably
located as near as possible to the circumference of the gong both for convenience
of manufacture and for obvious advantages in use. A spiral spring f holds the
lever in position, being attached to the lever inside the pivot e at g at one end and
at the other to a stud fixed to the base-piece at g'. The drawing shows the spring
attached to the lever by passing its bent end through an aperture therein. Often
the attachment is made by passing the bent end over a pin or stud fixed to the
lever at the same point. The particular method of attachment is immaterial.
The end of the lever is forked into two prongs, d' d. As herein shown the lever is
limited in motion by its side striking the central post e in one direction and in the
other by the projection d³, which strikes also against the central post c when
pressure is exerted upon the lever. The lever may, however, be constructed with
two prongs, beginning back of the central post, when the prongs will limit the
motion of the lever. So also if a curved standard, or any other means be employed
to support the gong, a pin placed in the same, or any other suitable place may be
used to limit the motion of the lever. At its outer end in the construction which
I here show the lever is formed into the familiar finger-piece of a bicycle-bell at d.
Means (not shown), however, for attaching the end of a rope or wire connecting
with a bell pull or push button may take the place of this finger-piece, or any
means may be used to oscillate the lever so as to cause it to perform its function,
that is, to propel the striker-mount from one side to the other and limit its motion.
At a point a little to one side of a line drawn through the pivot e and post c and
near the edge of the base-plate is fixed a post A provided at its upper extremity
with a head. This post serves as a support and a pivot for the striker-mount,
which is preferably, but not necessarily, east in one piece and consists of the hub m
from the upper end of which extends the crank or arm l. At the inner end of the
arm la pin is fixed to the crank which supports the striker k. The striker is a
lengthened oval as shown, althongh it may be diamond shaped or any other form
to permit its construction with two ends or striking points and a longitudinal
slot y which fits loosely over the pin a. The crank I may be constructed with a
shoulder adjacent to the striker or any similar means may be employed to hold the
striker in a position substantially at right angles to the crank as it moves back and
forth like a shuttle as shown at w in Figs. 5 and 7. A small pin n is attached to
the striker-arm just back of the striker and projects from its under side. Carried
by this pin are two rolls o and p. The smaller roll o is the lower in position on the
pin and is grooved around its circumference, or so constructed that the end of a
small wire spring may be conveniently coiled around it and engage it securely.
ris a small wire spring bent into a substantially semi-circular form and coiled
loosely around the central post at one end and attached securely to the small roll o

page_text: at the other. The prongs d'd bear against the roll p in operating the bell.
A small vulcanized fibre washers and small spring coiled round the pin may be
used in a familiar manner to hold the striker in place and prevent noise and rattling
in operation.
The operation is as follows: The spiral spring f holds the lever to the side of
the gong to which the spring is attached. By pressure upon the finger-piece the
prong d acting upon the roll p moves the striker-mount against the force of the.
spring away from that side. It will be observed that the construction and"
arrangement is such that the spring acts to throw the striker mount in both.
directions and that there is a center of equilibrium, as I call it, where the striker-
mount is at rest. The prong bearing against the roll p moves the striker-mount
up to this center where it is at rest, and the spring acts in neither direction. The
merest touch moving the mount in either direction brings it under the influence of
the spring which drives the striker-mount sharply towards the opposite side of
the gong. The roll p impinges against the opposite prong d' and the motion of the
mount is checked suddenly. The momentum carries the striker sharply against
the gong. The longitudinal slot permits this motion, and after impingement the
striker will instantly recoil or rebound. The slight friction caused, by the washer a
and springt will hold the striker away from the gong. Upon release of pressure
upon the finger-piece the striker-mount will be driven in the opposite direction by.
the prong d which is actuated by the spring when an impingement of the striker
will cause a second stroke or sounding of the bell in the same manner as just
described.
I wish to point out that although designed primarily as a double-stroke, bell,
this construction supplies with small variations a bell adapted to any use required
of a bell. By removing the spring it becomes a single-stroke bell. By rapid
manipulation of the lever it becomes an electric-stroke bell. By varying the form
of attachment it may be used as a door-bell or a call-bell and may be located near
to or far from the place of manipulation.
I have attempted to describe minutely one form of embodiment of my invention,
but I wish it to be understood that I do not limit myself to the exact form of
construction set forth, which it is plain may be varied in many of its details
without departing from the spirit of my invention. In my invention the need of
adjustment is done away with and the same striker-mount can be used in bells of
any ordinary size. The lever need not be of resilient metal and the parts are made
and assembled cheaply, without trial or adjustment, and with certainty of result
assured.
The essence of my invention rests in the adaptation of the peculiar striker to
the striker-mount, making possible the use of a non-resilient lever. I do not,
however, confine myself to the exact form of striker or slot. It is apparent that,
while the form shown may be the most effective, the form of striker and slot may
be varied and yet produce substantially the same result. For example, the striker
and slot, either or both, might be round. Or a solid striker might be arranged
with a shank which would move in a slot. I consider that any construction of
a striker so arranged on a striker-mount of substantially the character described
as to permit longitudinal motion to be within the spirit of my invention.
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. In gong-bells, the construction, arrangement, and combination of parts.
substantially as described and set forth.

striker-mount is driven against a prong of the lever by force of the spring the

page_text: striker will be carried forward by its momentum against the gong to sound the same
and immediately recoil in the line of its motion.
3. A gong bell consisting of a base-piece and gong, an elongated striker with an
elongated slot loosely carried on a pin on the striker-mount, and limited to a

by a spring in either direction, and a lever provided with prongs for propelling and
controlling the movement of the striker-mount so that when the striker-mount is
driven against a prong of the lever by the force of the spring the striker will be
carried forward by its momentum against the gong to sound the same, and
immediately recoil in the line of its motion.
4. In a gong-bell of the character described, an elongated striker having an
elongated slot loosely carried on a pin on the striker-mount, said striker-mount
being actuated by a spring in either direction, a lever actuated by a spring in one
direction, and provided with prongs for propelling and controlling the movements
of the striker-mount.
5. A gong-bell comprising in its construction a base-piece and gong, a striker-

rolls; a striker with a longitudinal slot loosely carried on said striker-shaft and held
by a washer and spring coiled round the shaft; a spring for actuating the striker-
mount fixed at one end to the lower roll, the other being coiled loosely round the
central post; and a lever, spring-actuated in one direction, having prongs bearing
against the upper roll to propel and control the movement of the striker-mount,
all so constructed and arranged that by pressure upon the lever the striker-mount
is moved past the center and by force of the spring said striker moving on its shaft
is impinged against the gong to sound the same.
