M. L. PARRY, OF GALVESTON, TEXAS.
1IMETHOD OF REPAIRING CIRCULAR-SAW TEETH.
Specification of Letters Patent No. 15,082, dated June 10, 1856.To all whom it may concern:
Be it known that I, M. L. PARRY, of Gal-
veston, in the county of Galveston and State
of Texas, have invented a new and Im-
5 proved Device to be Adapted to Circular
Saws for the Purpose of Enabling the Teeth
to be Hammered and Drawn Out with Fa-
cility; and I do hereby declare that the fol-
lowing is a full, clear, and exact description
10 of the same, reference being had to the an-
nexed drawings, making a part of this speci-
fication, in which-
Figure 1, is a side view of my improve-
ment. Fig. 0, is a plan or top view of the
15 same.
Similar letters of reference indicate corre-
sponding parts in the two figures.
My invention consists in having a sliding
or adjustable stop or mandrel fitted in the
20 upper part of an adjustable arm, said arm
being attached to the frame in which the
saw arbor is fitted and so arranged that the
stop or mandrel may be fitted between the
teeth of the saw as will be presently shown
25 and described.
To enable those skilled in the art to fully
understand and construct my invention, I
will proceed to describe it.
A, represents a square or rectangular
30so frame, in which a saw arbor B, is fitted.
C, represents the circular saw attached to
the end of the arbor B.
D, represents an arm the lower end of
which has a plate (a), attached to it. The
35 plate (a), has a slot (b), made in it and a
set screw (c), passes through said slot and
through a slot (d), made through one of
the side pieces of the frame A. The slot
(d), in the side piece of the frame A, andthe slot (b), in the plate (a), cross each 40
other at right angles as plainly shown in
Fig. 2. To the upper part of the arm D,
there is attached a socket (e), in which a
stop or mandrel E, is fitted. This stop or
mandrel is formed of a square bar of metal 45
having its outer end beveled or cut obliquely
to correspond in form to the spaces between
the teeth of the saw as shown clearly in Fig.
1. The socket (e), is not permanently at-
tached to the arm, but is connected to it by 50
a screw bolt (f), so that the stop or mandrel
may be inclined as desired -to suit the rake
or "pitch " of the teeth. The arm D, may
also be adjusted by means of the set screw
(c), so as to suit different sized saws. 55
The stop or mandrel may be adjusted in
or out from the saw teeth by turning a set
screw (g), which passes vertically into the
top of the socket (e). The teeth where
necessary may be hammered out upon the 60
end of the stop or mandrel, and in filing
the strop or mandrel keeps the saw steady
and prevents it from turning.
The device is simple, economically applied
and will be of great assistance to sawyers as 65
they may keep their saws in perfect order
with the greatest facility.
What I claim as new and desire to secure
by Letters Patent is-
The stop or mandrel F, fitted within an 70
adjustable socket (e), which is attached to
an arm D, the arm being secured to the
frame A, the above parts being arranged as
shown for the purpose specified.
