NOW KNOW YE, that in compliance with the said proviso, I, the said
Colin Mackenzie, do hereby declare my said new Invention respecting the said
Alarm Clatterer for Security of Windows and Doors against Housebreakers,
to be in form according to the Plan drawn in the margin of these Presents,
and which I describe more particularly as follows (viz):—

page_text: Imprimis (see Figure 1). A cogg wheel, fixed on a spindle, with a
common pulley fixed on the same spindle on the other side of the plate, which,
by receiving a motion, moves the clatterer.
.
Secondly (see Figure 2, 2). A part of the clatterer, its axis placed in one
side, it acts as a leaver, by which means it, makes a counter ballance to the
other part, and being fixed on either the frames of a window sash or bead will,
by turning the ballance side against the sash frame or bead, secure the sashes
so as to resist any attempt made by housebreakers to open them. It may be
made in several different forms, taking care to place the axis on one side, and
may be fixed to a window without the counterpart.
Thirdly (vide Figure 3). The other part of the clatterer, which, by its
motion, make the alarm; it axts upon its axis, with a joint to catch the cogg
wheel in one direction, and gives way in the other direction of the cogg wheel
going round. It hath a hammer on one end that strikes against a sonorous
body, and is connected to No. 2 by means of a chain, &c., to give it a counter
motion.
Fourthly (vide Figures 4, 4, 4, 4), which are parts cut out of the plate
wheroon the work is fixed for giving the sound a vent.
Fifthly (vide Figures 5, 5), the plate whereon the work is fixed.
Sixthly (see Figures 6, 6), the regulator, which is conducted to a door or
window shutter, by means of a chain, or India grass, &c., where it catches hold
of No. 7; it also, by being fixed on a window frame, sash, or bead, prevents
the sashes from making the least noise in stormy weather by means of its
elasticity, which presses the two sashes together.
Seventhly and lastly (see Figure 7), the catch fixed on the window shutter
which catches hold of No. 6, and, if pressed, lets go the clatterer and makes
an alarm.
In witness whereof, I, the said Colin Mackenzie, have hereunto set my
hand and seal, this Seventeenth day of November, in the twenty-sixth
year of the reign of our Sovereign Lord George the Third, by the
grace of God of Great Britain, France, and Ireland King, Defender
of the Faith, and so forth, and in the year of our Lord One thousand
seven hundred and eighty-five.

page_text: AND BE IT REMEMBERED, that on the Seventeenth day of November,
in the year of our Lord 1785, the aforesaid Colin Mackenzie came before our
said Lord the King in His Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stampt according
to the tenor of the Statutes made for that purpose.
