page_text: TO ALL PEOPLE TO WHOM THESE PRESENTS SHALL COME, I,
JOHN TRUSLER, of Cobham, in the County of Surry, Clerk, 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
Westminster, the Sixteenth day of September, in the seventeenth year of
His reign, did grant unto me, the said John Trusler, my executors, admi-
nistrators, and assigns, His said Majesty's especial licence, full power, sole
priviledge and authority, that I, the said John Trusler, my executors, admors,
and assigns, and every of them, by myself and themselves, or by mine and their
deputy or deputys, servants or agents, or such others as I, the said John
Trusler, my executors, admors, or assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, my
"NEW-INVENTED PAIR OF SNUPPERS THAT WILL NOT DROP THE WICK,
AND WHICH I APPREHEND WOULD BE EXCEEDINGLY USEFUL TO HIS MAJESTY'S SUB-
JECTS," within that part of His Majesty's Kingdom of Great Britain called
England, His Dominion of Wales, and Town of Berwick-upon-Tweed, in such
manner as to me, the said John Trusler, my executors, admors, and assigns,.
or any of them, should in their discretions seem meet, and that I, the said

page_text: John Trusler, my executors, admors, and assigns, should and lawfully might
have and enjoy the whole profit, benefit, commodity, and advantage from
time to time coming, growing, accruing, and arising by reason of the said
Invention, for and during the term of years therein mentioned, to have, hold,
exercise, and enjoy the said licence, powers, priviledges, and advantages,
therein-before granted or mentioned to be granted unto me, the said John
Trusler, my executors, admors, and assigns, for and during and unto the full
end and term of fourteen years from the date thereof next and immediately
ensuing, and fully to be compleat and ended, according to the Statute in such
case made and provided; in which said 'recited Letters Patent is contained a
provisoe, that if I, the said John Trusler, should not particularly describe and
ascertain the nature of my said Invention, and in what manner the same
was to be performed, by an instrument in writing under my hand and seal,
and cause the same to be inrolled in His Majesty's High Court of Chancery
within four calender months next and immediately after the date thereof, that
then the said recited Letters Patent, and all libertys and advantages what-
soever thereby granted, should utterly cease, determine, and become void,
anything therein contained to the contrary thereof in anywise notwithstanding,
as in and by the said in part recited Letters Patent, relation being thereunto
had, will more fully and at large appear.
NOW KNOW YE, that I, the said John Trusler, do hereby declare my
said Invention, and declare that the same is of the description and plan
following (the Drawing whereof is hereunto annexed) that is to say :---
His part
Fig. 1 is the snuffers as they appear when finished. B, B, is the
box of the snuffers, fixed on a bottom plate D, D, D, and covered with
an oval plate C. A, A, is a runner that runs in or within the box upon the
centre E, and shuts up the hole of the box where the snuff enters when
the snuffers are open. This runner is shewn at Fig. 10 as it appears when
taken out of the box; the parts A, A, and E, in Fig. 1, are described by
the same letters in Fig. 10. F, in Fig. 10, shews the thickness of the
runner, which is shewn in Fig. 1 by the broad dark line g.
of the inside plate that forms the inner part of the box, on which the
runner A, A, runs, and which prevents the snuff falling out at any time when
the hole of the snuffers is open. This plate is described at Fig. 9, where the
oval plate that covers the box is supposed to be taken off in order to shew the
inside; it is described in Figure 9 by the letters H, H, R. In Fig. 9, B 2
is that part of the box shewn at B 2 in Fig. 1, and B 1 in Fig. 9 is part
of the inside of the box, of which B 1 in Fig. 1 is the outside. M is the
cutter that snuffs the candle. In this view of the snuffers, they are supposed

page_text: to be half shutt in the action of snuffing the candle; when the snuffers are
open to their extent in order to snuff the candle, the part 6 of the runner A, A,
is at d, and the hole of the box a, b, c, is quite closed, so that none of the former
wick can fall out. As the candle is snuffed, and the cutter M approaches
the
box, the part 6 of the runner A, A, retires from a to c, and lets the snuff in,
and as soon as the snuff is pressed into the box by the cutter M, which
exactly fits and covers the hole, the runner A, A, immediately springs forward
to the left, and the part 6 is carried instantly from c to a, and in its passage
impells the snuff round the inner plate H into the inside of the box, and
entirely wipes or clears the inside of the cutter M, so as to leave no snuff
hanging to it. This operation will be clearer seen at Fig. 9, where a, b,
déscribes the hole of the box where the snuff enters; c, d, e, the space where
the runner Fig. 10 runs, the thickness of which; represented by F, fills up the
space between the outside of the box a, Fig. 9, and the inside plate H, and
which in its passage from c to c carries the snuff from d to c, round the end
of the inner plate H, into the interior part of the box I. The convext
cylindrical part E, G, of Fig. 10, when put in its place, exactly fits into the
concave part R of the inner plate H, H, R, in Fig. 9, in which it works as
on a centre or hinge. In Fig. 9, D, D, D, D, is the bottom plate of the
snuffers (seen at D, D, D, Fig. 1), the opening g, h, is the door or plate
where the snuff is taken out, and k is the point of that picker that picks the
candle. Fig. 2 shews the end of the box next the picker with the door open,
by which the snuffers are emptied. A is the opening which is closed by the
door B, held to by a spring. It remains now to shew how this machine
acts, which it does something on the principle of a gun lock, by means of a
tumbler, a trigger, a main spring, and a feather spring, as will be shewn at
Fig. 3. Near the joint at or on the upper handle is fixed a trigger at B, as
described at Fig. 7; the part where it is fixed to the handle is described at
Fig. 1 by the letter P, and at Fig. 3 by the letter A. At Fig. 3 the snuffers
are supposed to be opened to the extent in the operation of snuffing the candle,
and the view here given is that of the under side of the bottom plate of the
snuffers; described at D, D, D, in Figures 1 and 9; it is very evident that as
the cutter C, fixed to the handle D, is extended to the right, the trigger A, B,
fixed at A to the same handle, must proceed or move the contrary way, the
joint F of the snuffers being between A and C, the two moving points, that is,
the point A must approach nearer to the point B., In this progressive motion
the hook B of the trigger A, B, catches hold of the hook of the tumbler E
at S. To direct the trigger to its destined point, the feather spring H, fixed
at I, K, bears upon the back of the trigger at M, and keeps it close to the

page_text: tumbler E. As the candle is snuffed, and the cutter C approaches the box, the
trigger A, B, is drawn from B to A, and having caught hold of the tumbler
at S, pulls it round in its passage, for this tumbler runs upon a centre at E.
Now in its motion the neck of this tumbler d forces out the leg of the main
spring A from d to a, and in this motion the point c-of the trigger A, B, is
brought to the stud b, which stud 6 throws the hook B of the trigger off the
tumbler; that is, it causes it to quit its hold at L, and the tumbler being then
free, is thrown back into its former situation from a to d by the power of that
leg of the main spring N, that acts upon it at d; the tumbler is prevented
from being thrown too far back by a stud e, that stops it at its proper place.
Now it is the tumbler E that moves the runner Fig. 10 in the following
manner: This tumbler is described at Fig. 8, it having a square spindle
that passes through the whole box, coming through the under plate of the
square hole S, Fig. 9, passing through the cylindrical part of the runner,
Fig. 10, from G to E, coming out at S, and being fixed into the oval plate
that covers the top of the box at E, as in Fig. 1. Thus when the tumbler is
in the situation as described in Fig. 3, the part 6 of the. runner A, A (see
Fig. 1), is at a; when the point of the neck d of the tumbler is at a, as
described in Fig. 3, then the point 6 of the runner A, A, as seen in Fig. 1, is
carried back to c, and as soon as the tumbler is freed from the trigger, as it
will be when the snuffers are close shutt, the candle snuffed, and the point c
of the trigger A, B, is brought back to the stud b, as in Fig. 3, then that
part of the runner b, as seen in Fig. 1, springs forward from c to a as before
described, and shuts the snuffers up. Note, when the candle is snuffed and
the part 6 of the runner A, A, is at a, as in Fig. 1, that part of the runner
at A to the right is not seen, being concealed behind B 2. Fig. 5 is a plate
that covers the movements, being fastened on by a screw, Fig. 6 (as
shewn at Fig. 4). At the screw holes Q, at Figures 4, 5, 6, Fig. 11 is
the feather spring, Fig. 12 the main spring as seen at N, at Figure 3. Nota
Bene. These snuffers will be occasionally made with the box of a different
form, for, provided the part of the box where the snuff enters is a segment
of a circle, it is immaterial of what shape the other parts of the box are of;
the snuffers will also be made occasionally without the inside plate H, H, R,
as seen at Fig. 9, and with a different place to empty the snuff out at than
that shewn at Fig. 2. The springs also will be occasionally reversed, and of
course the runner that runs from a to c, as in Fig. 1, will then run from c to a.
The movements or springs will also be placed in various parts of the machine,
but the effect will be the same. In short, 'tis the principle upon which the
machine acts in which the Invention consists, for the machine may be made

page_text: everal ways upon the same principle, which consists in a tumbler, a trigger
r main spring, and a feather spring, as already described. Nota Bene.―These
nuffers will be sometimes made with the addition of the common circular
nuffer spring inclosed in the joint.
In witness whereof, I, the said John Trusler, have hereunto set my hand
and seal, the Third day of January, in the eighteenth 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
seventy-eight.
