fourteen years from the date of the said Letters Patent next and immediately
ensuing, and fully to be compleat and ended, according to the Statute in that
case made and provided; in which said Letters Patent there is contained a
proviso obliging me, the said James Chater, by an instrument under my hand and
seal, to cause a particular description of the nature of my said Invention, and
in what manner the same is performed, to be inrolled in His Majesty's High
Court of Chancery within one calendar month next and immediately after the
date of the said Letters Patent, as in and by the same (relation being there-
unto had) may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Chater, do hereby declare that the said Invention consists and is made
conformable to the several Drawings in the margin of these Presents.
In witness whereof, I have hereunto set my hand and seal, the Third
day of September, in the twenty-fifth year of the reign of our Sove-
reign 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.
EXPLANATION.
Fig. 1 is the gentleman's watch guard compleat in its proper size, as when
rivetted to the watch, the tongue or guard shut.
Fig. 2 is the ladies' watch guard compleat in its proper size. It is the hook
of the chain. a is the broad part to which the chain is affixed; b is the small
end, in which is contained the machinery exactly like that in the gentleman's
guard, explained in Figs. 25 & 26; a, d, is the guard or tongue open or thrown
by the spring against the broad or front part of the hook a, which prevents
the watch being unhooked by accident or otherwise, 'till it is pressed (by the
wearer. on the thumb piece d) against the back of the hook, in which is a

page_text: groove to keep it from projecting beyond its surface, and is therefore no
impediment to the wearer's unhooking it; c is a nib or stud acting the same
as f, Figs. 4, &c., and when moved down throws the guard as in the Figure,
but when moved upward confines the tongue in its groove when shut.
Fig. 3 is the note case compleat in its proper size, to be worn in the
common breeches pocket. It is curved to fit the thigh, and opens at the top
wide enough to admit the hand, by means of thin leather fastened at the
bottom and each side to the front and back, which lays in folds at each edge
when the note case is shut. a is the tongue, the same as for a watch; 6 is an
additional push piece, described Fig. 23; c, c, are screws to fasten the case
containing the machinery of the guard to the note case. The work is exactly
the same as the watch guard, Figs. 25 & 26, excepting the push piece, which
is shewn by B, Fig. 19, and has an additional spring, Fig. 21, connected to
the outer or additional push piece b. d, d, are screws or rivetts to fasten the
bolt or catch described Fig. 24; e is a notch for the nib and screw f to slide
in, which are fastened into the bolt that catches in the metal top 9, 9. By
moving down the nib f you open the note case, which will shut by only press-
ing it together. The tongue a, being thrown out by pressing and moving
downward the push piece b, it may be shut, but will not catch, but spring
forward 'till the push piece is pressed close and moved up which catches the
tongue when shut (the same may be said of the tongue of of all the guards).
When you put the note case in your pocket, the tongue catches behind the
pocket spring, described Figs. 8 & 10, and prevents the note case from coming
out 'till you put your hand down the outside of the note case, and turn your
fingers up to the push piece b, and push it up; then shut the tongue a, and
you may take out the case.
Fig. 4 is the watch guard on a larger scale, with the tongue shut. a is the
shank by which it is rivetted to the watch; b, b, is the joint of the guard case
screwed to the shank; c is the cover fastened on the guard case by the screws

of hard-thin brass, very elastic, with a cross piece rivetted at one end, with
the holes punched through it to sew it to the pocket, as shewn Figs. 8 & 9.
When the tongue of the watch guard is out (as in Fig. 7) it stops against
the pocket spring at the bottom of the tongue, near the joint, and the tongue
lays behind the pocket guard, and prevents the watch from being pulled out
'till the wearer pushes back the pocket spring with his finger, which lets the
watch pass by. B is the spring for the note pocket like the other, excepting
being made lengthways of 2 pieces, and curved to sit easy to the thigh with
a cross piece at each end to sew it to the pocket.
It is a piece of leather sewed between the

other end a is made flat to fit the notch b in the case. One end of the spring c
presses against the solid part of the case at b, and the other end against the
arm of the upper crank A, Fig. 18, in which is a hole that slides up and down
the spindle.
Fig. 17 is the bolt. a is the tail moved by the push piece, Fig. 19; b.is the
hole to receive the pin or screw, Fig. 13, on which it moves as its center; c
is the bolt head which catches into the hole d of the tongue, Figs. 7 & 15,
and prevents it coming forward 'till the bolt head is thrown back by the push
piece pressing down the tail a.
Fig. 18 is the cranks. A is the side view of the longest or upper crank.;
a is the tail rivetted to the small cranks; b is the arm (which the spiral
spring, Fig. 16, bears against), thro' which is a hole (shewed by the dotted
lines at 6). which slides up and down the spindle, Fig. 16, as shewn Figs. 25
& 26; B is the same shewed endways; a is the tail foreshortened; b is the
hole in the arm for the spindle; C is one of the short cranks shewed sideways;
D is another crank sideways; E is the same shewed edgeways.
Fig. 19, A is the push piece and spring of the watch guard. a is the tail
which discharges the guard; b is the nib which slides in the notch f, Figs. 6
& 13; d is the spring which bears against the bolt above its center (b, Fig. 17)
and confines the tongue by the bolt head holding it in the hole d, Fig. 15 (as
shewn, Fig. 25); but when the nib d is moved down, the tail a forces down
the tail of the bolt, and discharges the tongue by throwing back the bolt head;
the spring d, being then below the center b, ceases to act on the -bolt (as in
Fig. 26); B is the push piece & spring of the note guard, but has an addi-
tional spring b, c, rivetted at c; and at the end 6 is a round button which
springs against the note case into 2 holes hid by the outer push piece b,
Fig. 3, & shewn, Fig. 22.

page_text: Fig. 20 is the joint screw which passes through the nuckles a, a, Fig. 13,
the joint d, in the head of the shank, Fig. 11, and the hole 6 in the bottom of
the tongue, Fig. 15.
Fig. 21 is the side view of the additional spring (b, c, Fig. 19 B); b is the
button in which is a small nib that goes into the outer push piece at b, Fig. 23,
which covers 2 holes in the note case for the button to spring into, and pre-
vents the push piece from moving 'till, by pressing down the outer push piece,
the button is below the holes, Fig. 22, and may be moved up or down into
the other hole; c is the rivett of the push piece B, Fig. 19.
Fig. 22 is a notch and 2 holes in the note case under the outer push piece,
Fig. 23. a is the hole to receive the button b, Fig. 19 B, & Fig. 21, when
the tongue is out; but when the outer push piece is pressed close, the button
is pressed below the hole, and the nib slides up the notch by moving the push
piece 'till the button springs into the hole b, which throws out the bolt, as
before described.
Fig. 23 is the outer push piece b, Fig. 3; a, b, in dotted lines, are the holes
in the note case under the push piece; 6 is the nib in the button (b, Figs. 19
& 21) which connects the inner and outer push pieces; c, c, are the screws

nib & screw which slides in the notch e, in the note case, Fig. 3.
Fig. 25 is the watch guard compleat, with the cover off, shewing the inside
work with the tongue shut. To avoid any of the work being hid, the outer
part of the tongue (e, Fig. 4) is shewn by a dotted line, as is also the hole in
the tongue (d, Fig. 15) and part of the bolt head. The spiral spring is con-
fined by the upper crank which slides on the spindle, and the bolt is forced
through the tongue by the spring of the push piece bearing above its center.
Fig. 26 is the same, with the tongue open, which is shewn foreshortened &
the shank turned back. The upper crank is at the top of the spindle, and
the spiral spindle at ease.
The bolt head is thrown back, and the spring of
the push piece has lost its power, being below the center of the bolt.
Note. As the principle of all the guards is the same, they are not con-
fined to the above shape, but may be made of any metal, size, or form, and
adapted to any pocket-book, case, or instrument made of any materials fit for
the purpose.
