I, GEORGE ARTHUR RUSSELL GALLEY commonly known as Arthur Russell Galley
of 43 Higher Union Street, Torre, Torquay, in the County of Devon, Watch and
Clock Maker, lo hereby declare the nature of this invention to be as follows:-
The object of this invention is to produce an alarm bell which when once started
will sound for a period of say a minute or two according to the size and construction
of the bell, and which is applicable for shop door bells, burglar alarm bells for doors
and windows, and for other similar purposes.
According to this invention, I provide a mainspring of suitable size, and attach an
arm or lover to the winding spindle thereof. On this spindle I fix a pawl taking
into a ratchet affixed to or forming part of a toothed wheel which gears into a pinion
fixed upon an axis carrying a second toothed wheel. Other multiplying gear may be
used if required. The last wheel of the train actuates a pallet carrying the striker of
the bell. When used as a door bell, the action is as follows:-The bell and mechanism
are secured to a back or case which is affixed to the post to which the door is hinged.
A wire or chain is fastened to the end of the arm or lever on the winding spindle and
the other end of the wire or chain being provided with a loop for that purpose, is passed
over a hook or catch on the door placed in such a position that when the wire or
chain is looped thereover the mainspring is wound up. When winding the main-
spring the pawl rides loosely over the ratchet, hence the striker is not actuated.
When the door is opened, the chain or wire slackens and the spring immediately
begins to run down and in doing so, the pawl gears into the ratchet which actuates
the train of wheels and vibrates the pallet carrying the striker.

page_text: 1. GEORGE ARTHur Russell Galley, commonly known as Arthur Russell Galley,
of 48 Higher Union Street, Torre. Torquay, in the County of Devon, Watch and
Clock Maker, 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 object of this invention is to produce an alarm bell which, when once started,
will sound for a period of say a minute or two according to the size and construction
of the hell, and which is applicable for shop door bells, burglar alarm bells, for doors
and windows, and for other similar purposes.
According to this invention, 1 provide a mainspring of suitable size, and attach an
arm or lever to the winding spindle thereof. On this spindle, 1 fix a pawl taking into
a ratchet affixed to or forming part of a toothed wheel which gears into a pinion fixed
upon an axis carrying a second toothed wheel. Other multiplying gear may be nsed
if required. The last wheel of the train netuates a pallet carrying the striker of the
hell When used as a door hell, the action is as follows:-The bell and mechanism
are secured to a lack or case which is affixed to the post to which the door is hinged.
A wire or chain is fastened to the on 1 of the arm or lever on the winding spindle, and
the other end of the wire or chain being provided with a loop for that purpose, is
passed over a hook or catch on the door placed in such a position that when the wire
or chain is looped thereover, the mainspring is wound up." When winding the main-
spring, the pawl rides loosely over the rätehet, hence the striker is not actuated.
When the door is opened, the chain or wire slackens and the spring immediately
begins to run down, and in doing so, the pawl gears into the ratchet which actuatos
the train of wheels and vibrates the pallet carrying the striker.
And in order that my invention may be more fully understood and carried into
practice, I will now proceed to describe the same with reference to the accompanying
drawings, in which similar letters indicate corresponding parts in all the figures.
Figure 1 is a plan of the invention, Figure 2 is a similar view with the case
removed. Figure is a side elevation of Figuro 2 and Figure 4 is an enlarged
view of the mechanism with the hottom plate removed. Figure 5 shows a modifi-
cation of the invention.
Cis the mainspring fixed to the spindle D, the outer end being attached to the
standard E. Fixed to the spindle 1 is a ratchet wheel F which engages with a
pawl G affixed to the face of the toothed wheel H which is loose on the spindle D.
When the spring is wound up, the ratchet wheel F rides under without engaging
with the pawl G, but when the spring is running down, the teeth of the ratchet
whool F' engage with the pawl and carry it round, thus rotating the toothed wheel El.
This toothed wheel H. gears into a pinion arbor J carrying a second toothed
wheel K which may goar into other multiplying wheels, or as shewn in the drawing,
it may gear directly with the pallet L, on the spindle M on to which said spindle is

page_text: rigidly affixed the striker N. The spindles D, J, and M, work in bearings in the top
and bottom plates A and B. The spindle D is prolonged beyond the top plate A,
and may terminate in a square boss so that the spring may be wound with a key,
or as shewn in the drawing, it may have an arm or lever O rigidly affixed thereto.
One end of the wire or chain P is affixed to the arm O, the other end being passed
through a slot in the side of the top cover R. SS are staples through which screws
or nails may be passed to affix the bottom cover T carrying the bell Q and the
mechanism to the wall, door frame, or other convenient locality. 010¹ are stop
pins to regulate the travel of the lever O. If desired. the arm or lever O may be
dispensed with and the end of the wire or chain P affixed directly to the spindle D
or to a winding drum or barrel thereon, or other equivalent means may be adopted
for taking up the slack of the wire or chain when slackened by the movement of
the door, window, etc. It will be readily understood that when the door, window, etc.
is closed, the wire or chain P must be secured thereto quite tightly and the spring
wound up and also that the attachment must not be too near the hinge, but must be
at such a distance as will give an effective leverage, so that the slightest movement
of the door will slacken the wire or chain and allow the spring to run down and
actuate the train of wheels and strike the bell. When adjusting the apparatus, it is
simply necessary to pull out the wire or chain P thereby winding up the spring (,
and attach the end of the chain or wire to the hook or other attachment on the door,
window etc. Figure 5 is a sectional elevation shewing my invention as adapted to an
ordinary hand bell actuated by a push button U. In this modification, the mechanism
is exactly similar, and arranged in the same manner as in the bell herein before
described with reference to Figures 1 to 4. The arm or lever O is attached to a push
rod P' working in suitable guides V V and carrying the push button U. A spiral or
other spring Wrests against fixed stops a on the inside of one of the plates A or B
and is depressed by stops b fixed to or carried by the push rod P' when the push
button is depressed. The bell will continue to ring so long as the button is depressed,
the spring W returning the push rod P¹ to its initial position when the pressure is
removed.
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 1
clain is :-
The construction of an alarm bell in which the striker is actuated by a mainspring
and train of wheels when a wire or chain or the like is slackened or loosened, or when
a push rod is depressed, substantially as and for the purpose herein before set forth and
illustrated in the accompanying drawings.
