Improvements in Wood-working Machinery.
I, WILLIAM EDWARDS TAFT, of Dunmore, in the State of Pennsylvania,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention relates to that class of wood-working machinery in which the
material to be operated upon is held in suitable grippers, or frames, the cutting
device consisting of a spindle or mandril carrying a series of cutters or knives of
any suitable form, the mandril being driven at a considerable velocity.
My invention consists in the arrangement and disposition of the frame holding
the material to be operated upon and the adjustment and operation of the said frame
in relation to the revolving cutters.
Upon the upper part of the frame work which carries the spindle of the
revolving cutters I arrange a pair of frames each carrying a head, in the interior of
which head the wood is held and fixed. These heads are adapted to revolve in the
said frames and have notched flanges into which latches carried upon the frames
engage in order to retain the heads in any particular position.
These latches may be conveniently operated simultaneously by means of a shaft,
connected with the two latches, the said shaft being operated by any suitable
hand-lever.
The frames carrying the heads are made so as to be capable of adjustment
in a vertical direction towards the mandril being guided in suitable ways upon the
frame.
The adjustment of these heads may be effected simultaneously by means of a
shaft and bevel wheels imparting the motion to screwed spindles passing through
the upper portion of yokes which are supported on the main frame.
These yokes may be so constructed as to be adjusted longitudinally on the frame
of the machine this being conveniently carried out by their being connected to
plates which shall engage within lateral ways upon the frame, the plates being so
constructed as to permit of adjustment in any desirable lateral position.
The heads for carrying the material may be conveniently revolved by means of a
worm upon a spindle supported on the frame engaging into suitable cogs situated
on the periphery of the flange of the said head the said flange projecting outside
the sides of the frame carrying the heads.

Improvements in Wood-working Machinery.
I, WILLIAM EDWARDS TAFT, of Dunmore in the County of Lackawanna,
State of Pennsylvania, United States of America, Gentleman 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 fellowing statement :-
My invention is an improvement in wood working machines designed especially
for cutting, turning, and finishing posts and the like.
The invention consists in the details of construction hereinafter fully described,
and specifically pointed out in the claims.
In the accompanying drawings, Figure 1 is a plan view of the improved machine.
Figure 2 is a side elevation partly in central vertical section. Figure 3 is an end
view. Figures 4 and 5 illustrate modifications of the means for rotating the post or
other article which is to be operated upon.
In the drawings E represents the table or frame work of the machine, which
supports the operating parts. The main shaft C which carries the cutters is
journalled in bearings D and is driven through a band wheel secured thereto.
The bearings of the shaft C are fixed so that the said shaft and the cutters carried
thereby have rotary motion only.
The post or other article which is to be turned is held in heads G which are
circular in form, and are held in frames H being fitted thereto so as to be capable
of revolution therein. One of these heads is provided at each end of the machine,
and each head is provided with a series of wedges as shown at V which are operated
to clamp the post or other article operated on securely in place. The frames H
have vertical movement, so as to adjust the article to be turned in relation to the
cutters. These frames move in guides a formed on a yoke I and the upper part
of this yoke forms a bearing for a screw K which is in connection with the
frame H. A similar yoke I and screw K is arranged at the other end of the
machine, and these screws are provided with bevel-gears P¹ which are in connection
with bevel gears P secured to a shaft Q which shaft connects the screws K, K
through the bevel gears, and it is operated by a hand wheel R. By this connection
the frames H, H, may be adjusted vertically simultaneously. The yokes I, I have
outwardly extending portions, which are adjustably secured to horizontal plates J
forming a frame, these plates being shown in Figure 1 and having slots, so that the
yokes may be adjustable toward or from each other to allow for posts of different
lengths. The said plates J are fitted to slides X on the table-bed. At each end
of the frame a screw L is in connection with a screw-threaded box connected to the
plates J and these screws L are provided with bevel gears S¹ which mesh with
bevel gears S on the shaft T, which is operated by the hand wheel U. By turning
this wheel through the described connections the yokes carrying the frames H and
the article to be turned are moved laterally to any desired position. In order to
keep the frame or plates J from lifting in their lateral movement I provide the
clamps Y which pass beneath the slides.
The heads which hold the article to be turned may be kept stationary when
desired to operate on one part of the article at a time in turning an irregular form,
by means of latches N, secured to a shaft O, and operated by a lever W these
latches being adapted to engage with peripheral notches n in the projecting flanges g
of the heads and when the latches are in engagement with these notches as shown
in Figure 3 the post or other article to be turned will be held stationary. When
one side of the post has been acted upon by the cutters, the lever W may be lifted
and the post turned to present another edge or side. As shown on the right of
Figs. 1 and 2 the ring shaped head is provided on its outer side and near its
periphery with an annular flange, which projects beyond the frame and con-
stitutes a belt gear wheel or pulley M to which power is applied for revolving the
head and the work. When it is desired, however, to revolve the post A it is only

page_text: necessary to operate the lever W so as to disengage the latches N and by applying
power to the band wheel M connected to one of the heads G in this way the post
may be rotated. Instead of this manner of rotating the post I may as shown in
Figures 4 and 5 form one of the heads with a projecting flange, which in this
instance is formed into a worm-gear a' and revolve this gear through a worm b on
the shaft journalled in bearings e, e, and operated by a hand-wheel d.
The shafts Q and O have a splined connection as shown in Figure 2 so as to allow
for the adjustment longitudinally of one of the yokes I.
The shaft C which carries the cutters, may be provided with cutters of various
forms and these knives or cutters are ground twisting or beveled so as to give a cut
with the grain of the wood.
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 :---
1. In combination with the cutters and frame work, frames H having openings,
the heads G located within said openings adapted to revolve, said heads having
notched flanges 9 and the latches N carried by the frames and engaging said
notches substantially as described.
2. In combination with the frame work and cutters, the frames H having the
heads G journalled therein, a latch N on each end of the machine for engaging
the heads G and means for operating both latches simultaneously consisting of
the shaft and the lever W substantially as described.
3. In combination the frame the cutters the yokes I supported on the frame and
having vertical ways a the movable frames H guided in said ways the heads carried
thereby, and the adjusting screws K above the frames and passing through the
upper portions of the yokes substantially as described.
4. In combination the heads the frames H for supporting the same, the yokes I
for the frames carrying means for vertically adjusting the frames the plates J with
means for adjustably holding the yokes whereby they may be adjusted longi-
tudinally of the machine the main frame having lateral ways for the plates J,
and means for adjusting said plates laterally of the machine on the said ways
substantially as described.
5. In a wood working machine the combination of the supporting frame, the
cutters, the frame H having an opening and the ring head G having clamping
means and seated to revolve within the opening of the frame H said head having
an annular flange projecting outside beyond the frame H said flange being formed
into a driving wheel for the head substantially as described.
