Art. XVII.—Notice of the Brewster wool spinning frame— 
in a letter written in answer to inquiries from the Editor, 
by S. D. Hunpagp, Esq. and dated Middletown, July 
28, 1825. 
Peas Sr, 
In reply to your inquiries in your favour of the 21st.re- 
specting the Brewster wool spinning Frame, of which the 
Sanseer company of this place are the sole proprietors and 
builders, I have obtained the following brief, but | trust sat- 
isfactory statement from the Secretary of the company. 
The Brewster Frame, deriving its name from the inven- 
tor Mr. Gilbert Brewster, a distinguished mechanist and na- 
tive of this State, is so constructed that by the continued ro- 
winding up the yarn, to form the cap are 
to the attendant no othet labour than thatof ; 
tauch greaterconvenience. The length ofthe draft or quan- 
tity of slubing to be drawn out and the time of throwing in 
and continuing the twist being comprehended within the 
priaciple of the frame, they may be varied at pleasure. It 
is only necessary for the person in attendance, after ascer- 
taining the description of yarn, she is wished tospin, whether _ 
fine or cdarse, hard or slack twisted, to adjust the frame with 
a wrench tothe quality, shortening or protracting the peri 
of the closing of the jaws on the slubing as she may wish it 
finer or coarser, and varying the time of carrying on and off 
the belt from the twisting cylinder, according as she may de- 
sire her yarn hard ae twisted. When once adjusted, 
the frame continues in the same state producing a uniform 
thread, and possesses the additional advantage from its me- 
chanical construction, and the uniform regularity of its 
movements, of furnishing, if required, a thread slacker twisted 
for filling, and for warp, one harder twisted than can be spun 
On a je e expense of keeping a frame in repair,
