1, RICHARD MARKHAM of 111, Drummond Street, Euston Square, in the
County of London, Carpenter and Joiner, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to an improved appliance for setting the teeth of saws-of
both the circular and straight type, and it consists essentially of a spring-controlled
finger or striker adapted to be struck with a hammer and act on a shaped anvil, of
a frame pivotted to the part carrying the hammer and anvil to carry the saw and
enable it to be set at any desired angle with the said anvil, and of devices for
retaining the saws in position with respect to the striker.
In the accompanying drawing which illustrates this invention;
Figure 1 is a view in side elevation of the appliance showing its use for setting
the teeth of a circular saw.
Figure 2 is a similar view in section thereof and
Figure 3 is a view in plan thereof.
Figure 4 is a view in transverse section on line xx Figures 1 and 2, and
Figure 5 is a view in plan of the appliance showing its use for setting the teeth
of a straight saw.
Throughout the views similar parts are marked with like letters of reference.
The appliance cousists essentially of a metal head A either mounted on a

pivotted at a a finger or striker B controlled by a suitable spring C. The head
also carries a small steel block or anvil D located immediately under the acting
end of the striker B. To the head A is pivotted at a' a frame E which has a
longitudinal slot E' in the faces of which are cut longitudinal grooves e e and e¹ el
in which slide a pair of shaped plates F and F. The plate F carries a screw
which passes through a hole in the plate F¹ and is adapted to receive a spindle Ġ
which on being threaded down on to the screw f clamps the two plates together
f

the frame E, and so lock them in position. This spindle G forms a vertical stud
axle to receive a coned block H adapted to fit the eye of the circular saw and
clamp it down to a plate K shaped to adapt it to slide in the slot E' in the frame E
as shown. This plate K is preferably formed in two parts so that its thickness
may be reduced when the saw to be set is of the "ground off" type. The cone
blocks H are provided of various sizes so that circular saws with eyes of any size
may be readily fixed to the appliance.
In use after the circular saw is passed over the spindle G a cone block H of
the right size is dropped over the spindle and into the eye of the saw and after
the position of the spindle G is adjusted to bring the teeth of the saw under the
striker B, the screw G is screwed down to lock it in position on the frame E.
The saw is then free to be rotated about the spindle G so that each tooth can
be rapidly brought into position under the striker B which is struck with a
hammer to set the teeth.
For setting the teeth of straight saws the spindle G and the plates F and F1
are pushed back out of the way and the saw simply rests on the front of the
head A and on the plate K. The edges of the teeth of the saw bear against
the front edge of a guide L mounted to slide on the top of the head A so
that its front edge can be set with respect to the striker according to the depth
of the teeth of the saw by means of the screws l l.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improved appliance for setting saws, substantially as hereinbefore described
and illustrated by the accompanying drawing.
