page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER.
SIDEBOTHAM, of Charing Cross, in the Parish of Saint Martin-in-the-Fields, in
the County of Middlesex, Brazier, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-.
minster, the Twenty-third day of January, in the twenty-sixth year of His
reign, did give and grant unto me, the said Peter Sidebotham, His especial.
licence, full power, sole priviledge and authority, that I, the said Peter.
Sidebotham, my executors, administrators, and assigns, should and lawfully
might, during the term of years therein expressed, make, use, exercise, and.
vend, within that part of His Majesty's Kingdom of Great Britain called.
England, the Dominion of Wales, and Town of Berwick-upon-Tweed, my
Invention of "A NEW INSTRUMENT, THE END AND INTENTION OF WHICH IS TO GIVE
AN IMMEDIATE ALARM IN CASE OF ANY ACCIDENTAL OR OTHER FIRE;" in which
said recited Letters Patent is contained a provisoe obliging me, the said Peter
Sidebotham, by an instrument in writing under my hand and seal, to cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, to be inrolled in His Majesty's High Court
of Chancery within one calendar month after the date of the said Letters.
Patent, as in and by the said Letters Patent, relation being thereunto had,
may more fully appear.
NOW KNOW YE, that in compliance with the said provisoe, I, the said.
Peter Sidebotham, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, is described and ascer-
tained in manner following (that is to say):
A laver of brass, copper, steel, iron, or any other metal or wood, of such
length as the purchase of the pull or pulls may require (viz¹), from two to

page_text: twelve or eighteen inches or more, of a taper form, either quite streight, or
with a small neck, turned up at the largest extreme end to give a greater
purchase to the wire of the alarum or common bell which may communicate
to it. The smallest extreme end may either terminate taper, with one hole
drilled in it, or spread, with a dovetail and two holes, one in each extreme point.
The lower to be fixed under the cornice, or in any other part most convenient,
in a room, passage, closet, staircase, hall, or other place, and is kept in
a horizontal direction by means of a string or line, which must run round such
room, passage, closet, staircase, hall, or other place, and communicate to the
small end of the laver by means of a pully or pullies, one or more in a frame,
or by a common bell-crank. From the small end of the laver hangs a weight
of brass, lead, copper, iron, or steel, or any other metal; or, instead of the
pendant weight, the small end of the laver may be loaded with lead or other
metal, which, on the string or line being burnt, gives motion to the wire which
communicates to the large end of the laver from the alarum or common bell,
and of course gives an instantaneous alarm to the family. The weight must
vary according to the purchase of the pulls, and may be in any shape for the
wires or staircases or any other place, or in any other vertical or other
direction, the weight only without the laver may be found sufficient. The lavér
may be rivetted on a plate to affix to the wainscott, wall, or other partition, or
with a shank, to drive like a common crank (see No. 1), hereunto annexed.
It may work in a frame, open at one end or inclosed at both ends, with
pivots to work through the cheeks upon knife edges, like a pair of scales
(see No. 2), also hereunto annexed.. The hole may be at either the top,]
the bottom, or the center of the cheeks of the frame, as the pivots will
make in either way. It may work in a frame, open at one end or inclosed at
both ends, with pivots to work in centers in the cheeks. The centers may be
drilled or punched in either the top, the bottom, or the center of the cheeks of
the frame, as the pivots will work either way (see No. 3), hereunto also
annexed. It may work in a frame, open at one end or inclosed at both, with
round pivots to work through both the cheeks of the frame. The holes may be
through either the top, bottom, or center of the cheeks, as the pivots will work
either way (see No. 4), hereunto also annexed). The laver may work in a
frame, open at one end or inclosed at both, with a shank either to drive or
to rivet to a plate. The frame is fixed to the shank by a swevill in the crown
of it, by which means the laver may work in any direction; this may be with
pivots with knife edges, with pivots in centers, or with round pivots through
the cheeks, as described in No. 2, 3, and 4 (see No. 5, hereunto also
annexed). It may work with swevills in a triangle, either in a vertical or

page_text: horizontal direction, as may be required. The triangle may be with a shank, to
drive or rivet to a plate (see No. 6, also hereunto annexed). It may be rivetted
to a stud on a shank, or the stud may be rivetted to a plate (see No. 7, also
hereunto annexed). It may work on a stud forming a half joint with the bottom
of the neck of the laver. This stud may either form a shank to drive, or be
rivetted to a plate. The laver may work either upwards or downwards, or may
work in a frame, as No. 2, 3, and 4 (see No. 8, also hereunto annexed). It
may work with a rule joint, and may either drive or be rivetted to a plate, or
may be made to work in a frame, as No. 2, 3, and 4 (see No. 9, also
hereunto annexed). It may work as a purchase crank, with a long tail, and
may be with a shank to drive, or be rivetted to a plate (see No. 10, also
hereunto annexed). It may work as a purchase crank, on a plate, with
upright or flat cheeks, that will work various ways. The crank may work on
the rivitt with pivots in centers in the cheeks, with round pivots to work
through the cheeks, and with pivots working on knife edges through the
cheeks (see No. 11, also hereunto annexed). It may have an oblong
sole near the largest extreme, and which receives a long rivet, with either
a crutch or large round head. This rivet arises from a bar or shank, which
may either drive or be rivetted to a plate, and the laver will work under
or over the bar (see No. 12, hereunto also annexed). It may be a round
crank, with a long tail on a shank to drive or rivet to a plate, or it may be
worked in cheeks, as No. 11 (see No. 13, hereunto also annexed).
In witness whereof, I have hereunto set my hand and seal, this
