at. Nature’s bounty, a blefling to all 
other young people (as it fits them for 
their different employments, by giving 
bulk and ftreceth to the animal frame), is 
tohim, in refpeét to his trade, of but little 
advantage ; none but {mall boys can

who can help him into the world, or they 
would probably have difpofed of him dif- 
ferently ; weak, and ftinted in his growth 
by his profeffion, he is incapable of any 
employment which requires firength ; he 
is, upon the whole, too old and too large 
to fweep chimnies, and too young and 
too little for any thing elfe but a fecond

NEW PATENTS LATELY ENROLLED. 
MR. DURSEGG’s (WESTMINSTER) for 
Improvemenis upon Fire-arms, and their 
Lacks. 
HIS gentleman’s improvements upon 
the lock for fire arms confifts in a 
quicker. action, and is conftruéted in a 
much {maller centre axle on the tumbler, 
which ad's in, and is-fupported by, a le- 
cond bridle, which gces over the cock 
fixed on the outhde cf the lock. By the 
fame conftruétion, the axle of the tum. 
bler may be made as large as required, to 
fix the cock on a fufficiently large {quare 
to fecure the ccck from getting loofe. 
Another advantage is in pi‘ching the axle- 
hole in the lock-plate higher than ufual, 
which gives the cock a greater power in 
friking and cutting tre hammer more re- 
gularly, a better fire, and mere direétly 
into the pan. A new plan is alfo invented 
to take the lock to pieces, by means of a 
centre pin, that forms the axle through 
the bridle and tumbler; and, when drawn 
out, the cock and tumbler come out to- 
gether in one piece, through the upper 
part of the plate, and be put into its 
place, properly fixed as before, ina few 
feconds.« The open ;art of the plate is 
filled wp with a cover, enher to flide, or 
with a joint and {crew, or te flide in-and 
cut with the centre-pin. 
A new incthod of priming is defcribed, 
by which the exact quanuty of powder - 
aputt always be put inte the pan. The 
patentee has allo invented an improved 
pan and hammer, to expc] the damp, and 
to prevent the difappvintire:t of m.fling 
fire ; a new way to load al] kinds of fire- 
a:ms at the breech on the top of the bar- 
rel; a new nipper to cut the cartridge for 
priming, which may be made with a joint 
to fix on the léck or gun, with a fcrew 
and jcint to move or lay clofe to the gun 
when not wanted, or with a {pring to put 
en and off. , 
An improved mode of priming from 
the infide of the barrel, when charging, 
through the touch hole ; and an improved 
fight at the breech, are likewife defcribed. 
Mr. Egg has alfo improved the flock 
for piftols, by means of a fuppcrt cn the 
upper part of the ftock, as a ftop againft 
the hand, to prevent the piftol moving 
when fired; and of a fupport to reft acainft 
the arm or fhoulder. We have likewife 
a defcription of a pittol tor firing off can- 
non, to prime and load together withcut 
wadding ; and ancther for ramrods with 
an improved worm, the {pial part of 
which gces rourd a centre-beam, fimilar 
to a wooden {crew.

MR. JOHN SHARRER WARD'S, (BRU- 
TON, SOMERSET) for. a Machine for 
the Purpofe of doubling Silk, Cotton, 
Flax, Hemp, WWorfied yarn, or other 
Threads. 
By means of Mr. Ward’s inyention,' 
any number of threads of filk, &ce. may 
be doubled to the greateft certainty ; for 
ifat any time any one of the threads requir- 
ed to be doubled fiiould break, it will im- 
mediately top the other thread or threads 
until the broken thread fhall be re- pieced, 
which fecures a conftant double thread, or 
union of threads; and the manner in 
which the fame.is to be performed may be 
thus defcribed :— 
A reller turning round vertically or 
otherwife, carries with it a bobbin, which 
draws after it the two threads to be dou- 
bled, from two other bobbins }liced at a 
difiance from each other ; on each of the 
tops of thefe two laft bobbins is placed a 
ball and thread-wire fixed in it: the balls 
turn on the fame pins that the bobbins 
turn on. The machinery is fo conirived, 
that when either of the threads break, 
the thread-wire, threugh the ring of 
which it paffes, falls down, which caufes 
the
