IMPROVE- MENTS IN BELL MACHINERY
Year: 1847

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
PHILLIPS PARKER, of No. 48, Lime Street, in the City of London, send
greeting.
WHEREAS, in consequence of a communication made to me by a certain
Foreigner residing abroad, I am in possession of an Invention of "IMPROVE-
MENTS IN BELL MACHINERY," and whereas Her most Excellent Majesty Queen
Victoria, by Her Letters Patent under the Great Seal of the United Kingdom
of Great Britain and Ireland, bearing date at Westminster, the Twenty-
eighth day of January, in the tenth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto me, the said William Phillips
Parker, my exors, admors, and assigns, Her especial license, full power, sole
privilege and authority, that I, the said William Phillips Parker, my exors,
adñiors, and assigns, and every of them, by myself and themselves, or by
my and their deputy or deputies, servants or agents, and such others as I, the
said William Phillips Parker, my exors, admors, and assigns, should at any
time agree with, and no others, from time to time and at all times hereafter
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, and also within the Islands of Jersey, Guernsey, Alderney, Sark,
and Man, and Her Majesty's Colonies and Plantations abroad, "the said In- .
vention;" in which Letters Patent is contained a proviso requiring that I, the
said William Phillips Parker, shall particularly describe and ascertain the
nature of the said Invention, and in what manner the same is to be performed,

page_text: by an instrument in writing under my hand and seal, to be inrolled in Her
said Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Phillips Parker, do hereby declare that the nature of the said Inven-
tion, and the manner in which the same is to be performed, are particularly
-described and ascertained as follows, reference being had to the Drawing
annexed, and to the figures and letters marked thereon, that is to say:-
The nature of the said Invention consists in Improvements in Bell Machinery
for hotels, dwelling houses, cabins of ships, steamers, and other the like places,
wherein I am enabled, by peculiar mechanical contrivances, to indicato by a
register (having a single bell only to strike the alarm) the number of the
room from whence the alarm is given, and to dispense with the numerous bells
and cumberous and uncertain machinery now in use for such purposes. In
the annexed description similar letters will be used to refer to similar parts in
all the Figures.
Figure I. is a longitudinal elevation, shewing the principal of the machine
in a single movement. Figure II. is a ground plan of the same. Figure III.
is a perspective view of the drop. Figure IV. is a view of the face or register,
shewing the manner of arranging the drops so as to cover the various numbers.
Figure V. is a perspective view of the whole machinery, shewing the manner
of connecting a large number of rooms with it. The manner of constructing
and operating this machine is as follows:-Having provided a suitable bed or
foundation board or plate, which may be of wood or metal, and of a size pro-
portionate to the numbers of wire to be attached, I cut the long rectangular
grooves a in a horizontal direction. Into these grooves the slide bars 6 are to
be inserted. These are thin strips of metal, fitting the grooves in such a
manner as to permit them to slide backwards and forwards, and are secured in
place by the studs c, c. These slide bars have likewise several projecting
pins c, e, e, screwed in them, the use of which is to act upon the tumbler d.
These slido bars are worked by an arrangement of small compound levers or
cranks having a handle (y) attached to them, which projects from the face or
register side of the foundation board. As many connecting rods are fixed to the
crank pin as there are slides, as seen at h, h, h. These hang upon the levers i, i, i,
which completes the attachment. A barrel spring k is finally fixed to cause a
reaction of the crank after being used. The drop or tumbler d is the con-
trivance for shewing the number of the room from which the alarm is given.

page_text: The part e is a piece of thin sheet metal, cut in a circular form on one side,
and is attached by a pin or axis to the tumbler d, a screw being cut on the pin
to receive the part d. Holes are bored in the foundation plate at proper
distances along the line of the slide bar b to receive the pin and drop when
the tumbler d is screwed upon it. m is a swinging rack, suspended vertically
upon the bed plate. Along its front as many holes are perforated as there are
numbers upon the register. To this rack all the wires from the various rooms
aré brought and attached. The hammer of the bell or alarm is connected
with this rack by the lever n, having a notch near one end, resting in the forked
toe of the hammer handle o. The hammer o is secured to an angle iron strap,
bent as in the Figure, in order to bring it on a line with the rack and bell.
The letter p represents a series of arms or levers, secured on a pivot to the
foundation plate, and projecting at right angles from it. Their length is equal
to the arms of the rack m. On one end two holes are made to receive the
wires q, q, and the other end has a projecting piece or toe, on which rests one
of the arms of the tumbler d. The wires 9, 9, are then connected to the
swinging crank m at one end, and at the other to the ordinary bell cranks ?,
and led off to the various rooms in the house. The numbers seen in Figure IV.
are painted or otherwise affixed to the face or reverse side of the foundation
plate, Figure V., immediately against the tumblers d, so that when the drops /
are up these numbers shall be covered. The various parts of the apparatus
having been put up as described, can now be inclosed in a neat case, having a
door in the back to get at the works, the reverse side shewing the register of
numbers and the drops. The box can then be set up in some convenient
place near the clerk's desk, kitchen, or elsewhere. The modus operandi would
be as follows:-Suppose we wish to ring from No. 2, pull the wire S; this
draws back the arm p; at the same time the point of the toe leaves the
tumbler d, when the drop 6 is permitted to fall by its own weight, and exposes
the number, as seen at 2, Figure IV. The wire q, q, connected with tho
rack m, gives motion to the hammer, and strikes the alarm at the same time.
The barrel springs, seen in the Drawing, are for the purpose of causing the
return movement or reaction of the various parts to which they are attached.
In order to restore the drops to their former position, press down the handle g.
This moves the crank towards the stop t; the connections through i cause
the slides 6 to advance, and bring the pins e, e, e; against the teeth of the
tumbler d, aud throws the drop up again, where it rests upon the toe of the
arm p.
Having now described the nature of the said improvements, and the manner
in which the same are to be performed, I hereby claim as the said Invention

page_text: the combination of the drops with the tumblers d, drop lever or arms p, and
slides b, substantially in the manner and for the purpose herein set forth; and
such said Invention being, to the best of my knowledge and belief, entirely
new, and never before used within that part of Her said Majesty's United
Kingdom of Great Britain and Ireland called England, Her Dominion of
Wales, or Town of Berwick-upon-Tweed, nor in the Islands of Jersey,
Guernsey, Alderney, Sark, and Man, nor in any of Her said Majesty's
Colonies or Plantations abroad, I do hereby declare this to be my Specification
of the same, and that I do verily believe this my said Specification doth
comply in all respects, fully and without reserve or disguise, with the proviso I
in the said herein-before in part recited Letters Patent contained, wherefore I
hereby claim to maintain exclusive right and privilege to the said Invention.
In witness whereof, I, the said William Phillips Parker, have hereunto
set my hand and seal, the Twelfth day of April, in the year of our
Lord One thousand eight hundred and forty-seven.
