MR. WILLIAM NEWBERRY’S s (st. JOHN’s- 
STREET, LONDON), for an Invention of 
Muechinery for the Purpose of Sawing 
Wood, splitting or paring Skins, and 
other useful Purposes. 
HIS invention consists of a method 
of working an endless revolving saw- 
blade over two dumb-wheels or rollers 
to be used for any purposes to which a 
common saw can be applied: to this sort 
of saw a variety of machinery may be at- 
tached for guidmg the pieces to be cut; 
for the ma wnner of doing w hich, drawings 
with proper explanations are given with 
the specification, Jt will be difficult to 
render the invention intelligible without 
the aid of figures. The wheels run in a 
cast iron frame, each having an iron plate 
screwed behind it, to ‘prevent the -saw 
from running off backward. There is, 
of course, a bench or platform on which 
the piece to be cut is laid, and on this 
ate fixed two ‘semicircles of iron, the 
© 
centres of these are parallel to that part 
of the saw-blade which is‘even with the 
top of the bench; one of them is marked 
with the divisions of a circle, by which 
means on turning them in sliders, the 
bench may be placed at any angle to the 
biade of the saw, and there ‘fixed hy 
means of the screws, There are guides 
above and below the bench to keep the 
saw from running out, of its line; there 
are likewise two wedges to force down 
the lower wheel, go as to give the saw the’ 
necessary tension. ‘The piece to be cut 
may be brought forward to the saw, either — 
by the hand. or by passing it between 
rollers in the way practised for drawing 
iron, and therefore, on catising the 
wheels to revolve by any moving power, 
the saw continually passes through the 
piece till it isecut. Methods are exhi- 
bited for cutting circles of all sizes. The 
centre is determined by meaus of a 
socket sliding on a rod; the socket is 
1 fixed
