GEORGE WASHINGTON WALTON, OF SPARTA, TEXAS.
WOOD-WORKING MACHINE.
SPECIFICATION forming part of Letters Patent No. 448,388, dated 1PIarch 17,1891.
Application filed June 28, 1890, Serial No, 367,113. (No model,)To all wlom it n acy co7ncermn:
Be it known that I, GEORGE WTASHINGTON
WALTON, a citizen of the United States, re-
siding at Sparta, in the county of Bell and
5 State of Texas, have invented a new and use-
ful Wood-Working Machine, of which the fol-
lowing is a specification.
This invention relates to wood-working ma-
chines; and the object of the invention is to
ro effect improvements in devices of the same
general character heretofore existing.
To this end the invention consists in the
construction hereinafter more fully described
and as illustrated in the drawings, in which-
15 Figure 1 is a plan view of this machine.
Fig. 2 is a section on the line 2 2 of Fig. 1.
Fig. 3 is a perspective detail of the feeding
mechanism, and Fig. 4 is a section on the line
4 4 of Fig. 1.
20 Referring to the said drawings, the letter F
designates a suitable frame - work, within
which the hereinafter-described mechanism is
supported and journaled in any suitable man-
ner, and D is the main driving-wheel, prefer-
25 ably operated by a crank, as shown. This
drive-wheel is keyed on a shaft S, which is
cranked near the said wheel, and on said crank
is mounted a feed-rod R, which extends
through the frame-work and serves a purpose
30 to be more fully set forth presently.
B is a belt, which passes over the drive-
wheel D, over guide-rollers G, and along the
frame-work, out the front end thereof, and
over the cutter. On the upper side of the
35 frame there is but a single guide-roller; but
on the lower side thereof there are two, and
between these there is loosely mounted on the
said belt B a frame f, which carries a weight
W, adapted to impart a sufficient tension to
40 the belt to keep the same tight at all times.
K is a bar slotted longitudinally and pro-
vided with teeth in its slot, and P is a pawl
connected to the frame and normally engag-
ing said teeth to keep the bar distended. The
45 front end of the feed-rod R has a lateral
tongue r, which projects through the slot un-
der the pawl P, and also engages the teeth
therein, and as the crank reciprocates this
rod the bar K is fed forward step by step, one
50o notch at each revolution of the shaft, and the
pawl P holds it against a retrograde move-meant. The rod R has a loose bearing on the
crank of the main shaft, so that it can move
laterally, whereby its tongue 9 may be disen-
gaged from the teeth, and in the frame F, 55
where this rod passes therethrough, is a pin
N, which when in position bears against the
side of the tongue and holds it in engagement
with the teeth, but when withdrawn permits
the tongue to be moved laterally and disen- 60o
gaged. When the tongue r is in position be-
neath the tip of the pawl P and said tongue
is raised, it will also lift the pawl, because it
stands beneath it, as above described.
The slotted bar K carries side wings, ,wh ich 65
guide it in its movement where it passes
through the outer end of the frame F, and in
the latter is formed a hole of the proper shape
and size to permit the free passage of the bar
and its wings. The wings 1k terminate just 70
short of the outer end of the bar K, and said
end is provided with a transverse hole.
Through this hole is journaled a pin or bolt
h, upon the opposite ends of which are mount-
ed the heads HI, their inner ends next the two 75
sides of the bar K being preferably reduced,
as at b, to permit the band B to move there-
in. Within the two heads II and against the
ends thereof are secured the knives or cut-
ters proper C in any preferred manner. So
The operation of this device is as follows:
The head being brought against the material
or article it is desired to cut or rout and the
slotted bar K being retracted, a weight is at-
tached to the frame f and the wheel D is re- 85
voived. By the belt B and relative sizes of
the drive-wheel and cutter one revolution of
the former causes the latter to revolve a nuni-
ber of times or very rapidly when the drive-
wheel D is turned slowly. At each single 90o
revolution of the drive-wheel-that is to say,
once in about every ten to twenty revolutions
of the cutter-the bar K is fed forward by the
rod R the distance of one tooth, and thus the
cutter is gradually embedded in the material 95
or article being operated upon at the same
time that it is rotated at a high rate of speed.
To withdraw the cutter from the hole thus
formed, the whole frame can be retracted, or
the tongue r of the rod R can be raised and ioo
the bar K moved to the rear.
Considerable departure can be made from
