FI SAW
Year: 1886

page_text: I, SAMUEL C. ROGERS, of the City of Hamilton, in the County of Wentworth,
Province of Ontario, Dominion of Canada, Manufacturer, do hereby declare the
nature of said invention for FILING SAWS to be as follows:-
Figure 1 is an isometrical perspective view of a machine enibodying my
invention.
Figure 2 is a plan of bent lever, hereinafter describe-l.
In the drawings, A represents two double legs, bolted to and supporting
a frame A¹, the top of which is formed as a table projecting out at the back of
the frame, the legs and frame being rigid and stationary when the machine is
worked. In the vertical portion of the frame, and near the top, is a horizontal
slot, made to receive and allow to work in it the bent lever D, which is attached
at one end, by means of a screw, to the extremity of the table on its under side.
On the top of the table is a slotted arm, c, attached to the table so that it can be
fixed and moved to any desired position. On this arm is an adjustable chuck, L,
consisting of a concave base, F, a convex block, G, resting on the base and provided
with a slot G, a vertical cone, C, and lock-nuts. On the front of the concave
base is a lug carrying a spring-plunger, which engages with holes, formed in front
of the convex block, allowing the block to be held at any desired angle when or
sharpening cross-cut saws. An oscillating frame B, is connected with the legs at J,
and carries a shaft running in the journal-box R. This shaft carries the emery-
wheel C at one end, and a belt-pulley, H', at the other end. On the cap of this
box is the handle B. The spring K, attached to the connecting bars and having
its force controlled by the set-screw K¹, acts on the oscillating frame B in such
a manner as to carry the emery-wheel C' to the tooth of the saw, and keep it
contact therewith.
In the frame B are two screws M¹ and O, acting on the adjustable templet M,
hereinafter described, and the pillar 01 respectively.
To the side of the left leg A, and near the top, is attached the bracket a¹,
provided with a lug and set-screw P. This bracket supports the lever D, herein-
after described, while the set-screw P limits the action of said lever. The lever D,
attached at one end, as before stated, to the under side of the table A³, extends
through the slot before mentioned, and is bent at a suitable angle. On this lever
is the standard d carrying the pawl d', and on the top of this standard is a spring

page_text: so devised as to keep the pawl pressed against the saw when the lever is in use.
On this lever at the angle, is the adjustable templet M, which acts on the screw M¹,
when the lever is drawn forward, pressing the cscillating frame B outward in
shaping the back of the tooth.
In working the machine, the operator places the saw on the top of the convex
block or chuck L, securing it with cone and lock-nuts in such a manner that the
saw can be moved around easily, and then by means of the adjustable arm e and
the slot in same sets the saw in such a position that the right-hand side of the
wheel will be in line with the pitch of breast of tooth. He then grinds all the
teeth to the required depth and pitch of breast, being guided by screw O for depth
and by the side of wheel for pitch of breast, using the handle B₁ for this latter
operation. He then allows the pawl to engage the tooth immediately to left of
wheel, and moving the lever forward until it touches the adjustable stop P in
bracket al, the breast of that tooth is brought into exact line with the right hand
side of wheel. At the same time the adjustable templet M, acting against the
screw M¹, causes the wheel to move out in such a manner as to allow the wheel to
grind the back of tooth to shape of templet. He then moves the lever back,
allowing the pawl to engage, the next tooth, at the same time allowing the wheel;
by means of the adjustable templet and the screw M¹, to move into the throat of
the tooth, the back of which has just been ground. It will thus be seen that ench
tooth will be ground to the exact shape of the preceding one. The pawl and
templet being both on the lever and working conjointly, the effect is to make and
keep the saw true and jointed.
In sharpening cross-cut saws the operator secures the saw as before described,
and releasing the spring-plunger in concave base be tips the saw to the angle
required for the proper filing of a cross-cut saw, and fastens it by again engaging
the plunger in the proper hole in front of the convex block. The saw is then
moved in position before the wheel, and the operator proceeds to sharpen it by
using the handle B¹ on the bearing-box R.

page_text: I, SAMUEL C. ROGERS, of the City of Hamilton, County of Wentworth,
Province of Ontario, Dominion of Canada, Manufacturer do hereby declare the
nature of my invention for SAW-SHARPENING MACHINES and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My inventions relates to improvements in machines for sharpening saws.
And
it consists in the construction and arrangements of the parts hereinafter mentioned
and fully described and claimed.
Reference being made to the accompanying drawings, in which :-
Fig. 1 is an isometrical perspective view of a machine embodying my invention.
Fig. 2 is a plan of bent lever, hereinafter described.
Fig. 3 is a sectional view of the saw-supporting device. And,
Fig. 4 is an elevation thereof.
In the drawings, A represents two double legs, bolted to and supporting a
frame, A¹, the top of which is formed as a table projecting out at the back of the
frame, the legs and frame being rigid and stationary when the inachine is worked.
In the vertical portion of the frame, and near the top, is a horizontal slot, made
to receive and allow to work in. it the bent lever, D, which is attached at one end,
by means of a screw, to the extremity of the table on its under side.
On the top
of the table is a slotted arm, e, attached to the table so that it can be fixed and
moved to any desired position. On this arm is an adjustable chuck, L, consisting
of a concave base, F, a convex block, G, resting on the base and provided with a
slot, G¹, a vertical cone, C¹¹, and locknuts. On the front of the concave base is a
lug, carrying a spring-plunger, which engages with holes formed in front of the
convex block, allowing the block to be held at any desired angle when sharpening
cross-cut saws.
An oscillating frame, B, is connected with the legs at J, and carries a shaft
running in the journal-box, R. This shaft carries the emery-wheel, C¹, at one end
and a belt-pulley, H, at the other end. On the cap of this box is the handle, B¹.
The spring, K, attached to the connecting-bar, s, and having its force controlled by
the set-screw, K¹, acts on the oscillating frame, B, in such a manner as to carry the
emery-wheel, C¹, to the tooth of the saw and keep it in contact therewith.
In the frame, B, are two screws, m³ and o, acting on the adjustable templet, m,
hereinafter described, and the pillar, o¹, respectively.
To the side of the left leg, A, and near the top, is attached the bracket, a', pro-
vided with a lug and set-screw, P. This bracket supports the lever, D, hereinafter
described, while the set screw, P, limits the action of said lever. The lever, D,
attached at one end, as before stated, to the under side of the table, A¹, extends
through the slot before mentioned, and is bent at a suitable angle. On this lever
is the standard, d, carrying the pawl, d', and on the top of this standard is a spring
so devised as to keep the pawl pressed against the saw when the lever is in
use. On this lever, at the angle, is the adjustable templet, m, which acts on the

page_text: screw, m, when this lever is drawn forward, pressing the oscillating frame, B,
outward in shaping the back of the tooth.
In working the machine, the operator places the saw on the top of the convex
block or chuck, L, securing it with cone and locknuts in such a manner that the
saw can be moved around easily, and then by means of the adjustable arm, c, and
the slot in same, sets the saw in such a position that the right-hand side of the
wheel will be in line with the pitch of breast of tooth. He then sharpens all, the
teeth to the required depth and pitch of breast, using the handle, B¹, for this latter
operation. He then allows the pawl to engage the tooth immediately to left of
wheel, and moving the lever forward until it touches the adjustable stop, P, in
bracket, a', the breast of that tooth is brought into exact line with the right-hand
side of wheel. At the same time the adjustable templet, m, acting against the
screw, m¹, causes the wheel to move out in such a manner as to allow the wheel to
3
grind the back of tooth to shape of templet. He then moves the lever back,
allowing the pawl to engage the next tooth, at the same time allowing the wheel,
by means of the adjustable templet and the screw, m¹, to move into the throat of
the tooth, the back of which has just been ground: It will thus be seen that cach
tooth will be ground to the exact shape of the preceding one. The pawl and
templet being both on the lever and working conjointly, the effect is to make and
keep the saw true and jointed.
In sharpening cross-cut saws, the operator secures the saw as before described,
and releasing the spring-plunger in concave base, he tips the saw to the angle
required for the proper sharpening of a cross-cut saw, and fastens it by again
engaging the plunger in the proper hole in front of the convex block. The saw is
then moved in position before the wheel, and the operator proceeds to sharpen it
by using the handle, B, on the bearing-box, R.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination of a slotted arm, e, concave base, F, convex block, G, and
cone, C, provided with screw and jam-nuts, as described.
