HE figures annexed to this specifi- 
-ention, shew the fly turing upon - 
the ‘apatite with its arms pointing up-= 
wards. ‘The bottom of the spindle rests 
upen, and turns in a step fixed in a 
rail, and passes through a collar in the 
rail which supperts the fly restrag on the 
washer. The upper part of the spindle 
is smaller in diameter’ than the bobbin, 
so.as to leave a shoulder for it to vest on 
A pulley is fixed on the spindle, and “an- 
other on the socket-of the My. The fly, 
turned by the palley, from the dram, 
twists the thread as delivered from the 
rollers of the machine, and by nygeans of 
the thread turns the bobbin. © The 
dfaught, or winding wp of the thread on 
the bobbin, arises from the friction of the 
ursiie of the bobbm, against the small 
part in the spindle, and from the bottom 
of the bobbin, against the shoulder of the’ 
or washer fixed on it. This 
is regulated by the spindle, 
whichis turned by another pulley from 
another drum, in the same direction as 
the fly, in a contrary direction, or remains 
stationary, as. the quality of the thread 
requires. 
The principle of this improvement, as 
distinct from the o}d mode, consists in 
inverting the fly, and giving it a separate 
motion. from the spindle. . The improve- 
ment arises chiefly from these circum- 
stances; first as the fly is the chief agent 
in twisting the thread, it is the only part 
Kept in rapid motion ; ; consequently there 
is a great saving of power, since, in the 
old machine, the spindle and fiy turned 
together at the same speed. Secondly. 
The bobbin, -fly, and spindle; having 
their distinice and separate motions, the 
draught, or inclination of the thread to 
wind up, can be regulated to the utmost 
exactness, and, when regulated, will re- 
main invariably the same af whatever 
speed the machine shall turn ; whereas,

duces a variation of draught, 
breaking the thread, and causing much 
waste. Thirdly.” On ‘account of the 
inverted position of the fiy, the bobbin 
can be taken off, and put on with expe- 
dition; whilst in the old plan, it was ne- 
cessary to stop the spindle, and unscrew 
the fiy from the top, orto take out the 
spindle. By these improvements, the

In vol. xxvii. p. 493, of the’ Monthly. 
Magazine, we have viven! an account of 
another patent, ‘obtained hy this. ‘gentle- 
man, which, theugh connected with pens 
and writing, has mot the’ ‘saine. object as. 
that now. before ue. ‘Fhe present’ inven 
ion consists, first in Raving a valve acting’ 
with a'spiral Spring, or a screw ‘to affix on 
the ‘tube ‘of the pen, to Supply it occa-’ 
sionally with’ air to force’ ink. into the 
socket of the pew.. “Secondly : In ‘having

vent the ink flowing too’ ‘freely into the 
mib, The pen consists ‘of thiee parts, 
joined ‘tozetlier by screws, bad inay be 
made of any sort of metal. ‘The'ts part 
of the pen is called the box? thé ‘ext ‘is 
the tube, and the third is’ ‘the socket: 
it is madé in three divisions, for: the pur- 
pose of cleaning the pen, incase it ‘should 
get foul, and to supply thé tube with ink, 
and to ae any of the different’ sabihets 
to the tube at pleastte. The box ‘has a 
bottom soldered in, having a hole i in it to 
admit’air to pass jiito’ the'tube through 
the top of the box; it cotitains spiral 
spring’: a ‘small rod: having “a “plate, | Or 
valve at the bottom of it, covered’ with >

bottom of the bex, ‘bar it is not’ so thick

the knot, and confines the spring: im the 
box : the spring pressing’ upwards against 
the knob, keeps the valve close to the © 
bottom of the box, to prevent the ink 
getting out of the top. The tube has @ 
bottom soldered in above the joint, that 
unites 1¢ with the socket: in the bottom 
is a small pipe tor the ink to pass through 
“into the socket. The socketis hollow, 
and has a hole in -front_to admit the ar,
