Improvements in Wood Working Machines.
I, JAMES MONTGOMERY BURKE, of 272 Main Street Buffalo, in the State of
New York, one of the United States of America, Engineer, 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:-
My invention relates to certain improvements on the wood-working machine
described in the United States Patent of W. E. Taft, No. 434846, dated

My improved wood-working machine consists essentially of a suitable supporting
frame, carrying a revolving cutter hea!, a carriage, which is provided with rotatable
wood-holding chucks, and is arranged to reciprocate relatively to the cutter so as
to present the wood thereto, and mechanism for imparting and controlling the
reciprocating movements of the carriage, and for giving the chucks a partial
revolution at each reciprocation, so as to dress the wood into any desired polygonal
shape and also mechanism for causing the chucks to make a complete revolution
while the carriage remains stationary, so as to produce cylindrical forms. The
knives on the cutter head are made with irregular cutting edges, as indicated in
Fig. 3, so as to dress the wood to any desired ornamental form, either circular,
square, hexagonal, or octagonal etc.
In the drawings the frame is represented as consisting of the side-frames A A',
connected together by suitable cross-bars B B'. C is the revolving cutter-head,

page_text: provided with the knives a, having cutting edges of the desired form, and sustained
by a shaft journaled in suitable boxes D D¹ on the side frames. E is the driving
pulley, by which power is applied to the machine. The reciprocating carriage
consists of the standards F F, connected together by the transverse bars G G³,
which are arranged to slide on the side frames A A¹, being held down by gibs b,
Figs. 4 and 6, engaging with the ribs c projecting inward from the side frames.
The standard F is bolted to the bars G G¹, while the standard F¹ is gibbed or
otherwise fitted to the bars, so that the distance between the standards may be
increased or diminished, as indicated by the dotted lines F, Fig. 3, so as to adapt
the machine to working sticks of lumber, H, of different lengths. d and dare
screws arranged parallel to each other, and connected together by the shaft e and
bevel gears by which the adjustment of the standard F is effected. The
screws d d' engage in nuts g g on the standard F¹ and are supported in suitable
journals on the bars G G₁ at their other ends. The shaft e is provided with
suitable supports, and at one end it is squared or fitted for the application of a
rench, so as to secure the simultaneous movement of the screws.
"
Each of the standards F F is fitted with a head 11', arranged to slide in suitable
ways or guides, and connected together by the shaft h, bevels i i¹, and screws m m³,
so that the heads may be simultaneously adjusted relative to the cutter C. The
standards are provided with suitable openings within which the heads I I¹ slide.
Each of the heads carries a rotary chuck or wood-holding device, JJ, the
construction of which is shown more in detail in Figs. 9 and 10. The heads are
provided with circular recesses formed partially in their lower edges and partially
in the caps, n, Fig. 6, in which the circular bodies K, Fig. 9, of the wood-holders
revolve.
The simultaneous rotary movement of the wood-holders is secured by the
transverse shaft M, journaled in the heads II', and provided on either end with
the gears, o o, meshing with the gears p p² on the bodies of the wood-holders.
Any suitable form of chuck or clamping device may be employed in the wood-
holders, to secure it firmly in place therein. A scroll-chuck of an ordinary form,
is represented in Fig. 10 in which the sliding jaws are provided with pins
projecting into spiral slots in the plate of the gear L, which is secured to the body
of the wood-holder by the disc k, and screws q. By turning the gears L L¹ the
jaws are caused to slide in and out, so as to clamp or release the wood. In order
to provide a convenient means for operating the chucks, I employ the trausverse
shaft N, journaled in the heads II and the handles OO¹ provided with the
dogs, engaging with ratchets on the shaft, which are attached by suitable
sleeves to the pinions ss, which mesh with the gears LL' on the wood holders.
The dogs are ordinarily held out of engagement with the teeth of the ratchets r r
by the springs u, but, by grasping the outer end of the handles, the hand-pieces
are pressed inward, compressing the springs, and causing the dogs to engage with
the teeth of the ratchets, so that the pinions & s¹ and the gears L L' are caused to
Turn either direction by a to-and-fro movement imparted to the handles, thus
opening or closing the chucks. The ratchets and pinions are loose on the shaft N,
being provided with suitable collars by which they are held in place lengthways
thereof.
The shaft N also serves to support the latches tt' which engage with the notches
in the rings 4, 6 or 8 on the wood-holders. These latches, when engaged in the
notches of the rings, serve to prevent the wood-holders from revolving during the
cutting operation, so that the wood can be dressed square, hexagonal, or octagonal,
according to the number of notches in the ring employed.
Provision is made for adjusting the latches lengthways on the shaft N, as
indicated by the dotted lines in Fig. 9, so as to cause them to engage with any one
'of the rings. The shaft N is slotted lengthways, and the latches are provided with
keys and set screws, by which they are secured to the shaft N so as to be moved
simultaneously by a partial rotation of the shaft, to engage or disengage them from
the rings on the two wood-holders.

page_text: The latches are held in engagement with the notches in the rings by any suitable
springs,—a convenient arrangement by which the springs are made variable in
tension and adjustable lengthways, being represented in Figs. 10 and 11, in which
Qis a short shaft or stud inserted in a hole in the head I, and carrying a hub v,
around which the spring to is coiled, and the ratchet wheel x. A pawly pivotted
on the head engages with the teeth of the ratchet. At one end the spring w is
The
fastened to the hub v, and the other end rests in a groove in the latch t.
stud Q turns in the head, being secured therein by a set-screw entering a groove or
other suitable device. The hub is splined on the stud Q. The exposed end of
the stud is fitted for the application of a wrench, so that the tension of the spring
may be varied. For convenience of illustration, the spring and ratchet are omitte l
in Fig. 3, but it will be understood that both of the latches t t¹ are provided with
the springs.
Proceeding now to a description of the mechanism for imparting the reciprocating
movement to the carriage, it should be understood that this is effected automatically.
by reversing the rotation of the feed-screws, R R¹ by means of the change-
gears S S. Continuous rotary motion is imparted to the shaft T, arranged in
suitable supports across the end of the machine, by any suitable ineans, such as
the belts and pulleys W W₁ shown in Fig. 3, by which the shaft is driven from the
cutter-head shaft. The shaft T carries a gear U, which meshes with the gear S',
which meshes with the gear S. Parallel with shaft T is arranged the shaft V,
which carries the gear X, and it is provided at each end with the bevel gears, z z¹,
by which it is connected with the feed screws R R¹. The gear X is so arranged
on the shaft V that either of the gears S or S₁ may be engaged with it. These
gears are supported on a swinging arm Y pivotted on the shaft T. Rotary motion
in either direction may be imparted to the shaft V, and consequently to the feed
screws R R', by meshing one or the other of the gears S S with the gear X.
When both the gears S S₁ are out of mesh with the gear X, the shaft V and the
feed-screws and carriage will remain stationary. This is the position indicated by
the full lines in Figs. 1 and 2. The feed-screws are connected with the carriage
by means of the nuts at a attached to the ends of the bar G¹.
In order to cause the carriage to automatically reverse its motion at each end of
its travel, I employ the shifter-bar C, attached at one end to the arm D' on the
frame Y carrying the gears S S', and arrange suitable cams or levers at each en l
of the path of the carriage, so that the gears S S will be alternately engaged with
the gear X by the movement of the carriage itself. E³ F³ are cams arranged in
the path of the carriage at each end thereof, and connected with the shifter bar C*
by the rock-shafts and arms e* e³. A lug or arm on the carriage comes in
contact with the cam E at the end of the movement towards the left hand, and
shifts the bar C so as to disengage the gear S from the gear X, and engage the
gear S¹ with it, so as to reverse the direction of the rotation of the shaft V and the
feed-screws R R¹. At the right hand end of the travel of the carriage, a similar
operation takes place, the cam F³ being moved, so as to disengage the gear S
from and to engage the gear S with the gear X. In order to effect the reversal
with certainty, I employ the spring bolts 1, Fig. 1, which are arranged in
adjustable reversing blocks, g g', carried by the cross-bars G G¹ of the carriage.
When the spring bolt comes in contact with the cam E', the spring on it is
compressed, until its resistance becomes sufficient to shift the bar C³, disengaging
the notch from the plate 3, after which the spring expands, and forces the bar
quickly to the extremity of its travel, insuring the engagement of the gear S with
the gear X, and of the notch with the plate or catch. The spring bolt slides
through an eye k on the reversing block y', which is made adjustable lengthways
by the screw passing through a slot in the block and threaded into the lower
part of the arm attached to the cross-bar G' which carries the nut a' of the feed
screw R. The end of the spring bolt which comes in contact with the cam E' is
enlarged, and its other end is provided with jam-nuts by which the tension of the
Spring may be adjusted.

page_text: The construction and arrangement of the spring bolt f' Fig. 1, which comes in
contact with the cam F³, is similar to that already described for the spring bolt f*,
except that in order to provide for stopping the reciprocation of the carriage at the
right hand end of its travel, where the wood is most conveniently removed or
replaced, the reversing block g is made to slide to and from the side frame A, as
indicated most plainly in Fig. 4, so as to bring the spring bolt f out of line with
the cam F. The rock shaft is provided with an auxiliary cam H. The
reversing block 9' carries an additional push-bolt or striker k³, Figs. 4 and 5.
When the operator desires to stop the movement of the carriage at its right hand
end, he pulls the lever 1 outwards, shifting the reversing block g', from the position
shown in full lines in Fig. 4 to that represented by the dotted lines, and moving the
spring bolt out of line with the cam F³, and bringing the push-bolt k³ into line
with the anxiliary cam H³, so that there being no spring on the bolt k³, the shifter
bar C will only be moved far enough to disengage the gear S¹ from the gear X,
the bar resting with the shallow notch on the plate. In this case both the
change-gears are disengaged from the gear X, and the carriage remains stationary
at the extremity of its travel to the right. The shifter-bar C3 is provided with one
or more adjustable weights J, by the adjustment of which lengthways, the amount
of resistance offered by the notches, h, h, against disengagement from the plate³
may be varied. The reversing block g' is fitted by a dovetailed slide to an adjustable
block 13, secured by bolt j to an arm projecting downwards from the cross-bar G.
The lever is pivotted to the block 13 at m³, and its lower end is jointed to the
sliding reversing block 9. The push bolt is provided with jam-nuts, arranged
on each side of a flange projecting downwards from the reversing block as indicated
in Fig. 5, so that it may be adjusted lengthways.
If the operator now desires to start the carriage again into operatiou, be brings
the spring bolt into line with the cam F3 by pushing the upper end of the lever 1³
inwards, and then, by means of the lever J pivotted at n³, he disengages the central
notch in the shifter-bar from the plate, and shifts the bar so as to cause the
gear S to mesh with the gear X. The carriage will now continue to reciprocate
so long as the arrangement described is maintained. In order to facilitate the
disengagement of the notches from the plate, I provide the lever J* with a pivotted
hand-piece, p³, connected by a rod q³ with the shifter bar C, so that, by pressure
on the hand-piece, the shifter is lifted positively a short distance, as indicated by
the full and dotted lines in Fig. 2. The joints between the bar and the lever J
and the arms et e' are slotted to permit this movement.
If however the operator desires to move the carriage until the wood-holders are
directly over the cutter,-in position for doing round work, he leaves the reversing
block in the position in which the push-bolt k³ is in line with the auxiliary
cam H, and starts the carriage, which will now move inward, until, when the
wood-holders are directly over the cutter head, the arm on the reversing block g
will come in contact with the lever L³, connected with the rock shaft 6, (in line
with cam H), which lever will be pushed downward, thereby shifting the bar C
and stopping the motion of the carriage. The carriage may be now again returned
to the right hand end of its travel, by the use of lever J. The lever L³ is
adjustably connected to a lug on the boss of the cam H³, by means of a screw, s³,
Fig. 1 passing through a slot in the lever. The inner end of the lever L is turned
upwards into the path of the arm. By the proper adjustment of the lever the
carriage may be stopped with the centres of the wood-holders exactly over the
centre of rotation of the cutter-head C.
In order to impart a continuous revolution to the wood-holders, for turning round
work, I drive one of the wood-holders by a worm, t2 and worm-gear u². It is
necessary to provide means for engaging and disengaging the worm and worm-gear
and also for lifting the latches tt out of the notches in the rings on the wood-
holders, and for keeping them out while the wood-holders are revolving. Both of
these purposes I accomplish by means of the hand lever N¹, which operates an
eccentric which moves the worm into engagement with the worm-gear, and also

page_text: acts as a cam to turn the shaft N and hold the latches away from the rings. The
shaft N extends beyond the head I, and is provided with a bent arm L', which is
depressed by the movement of the lever N₁ so as to lift the latches out of the
notches in the rings. The operation is indicated by the full and dotted lines in
Figs. 1, 10, and 12. As the lever N' is swung outward, the cam portion v', Fig. 12,
of the lever, depresses the arm L' and turns the shaft N so as to raise the latch t
out of the notch in the ring on the wood-holder. The latch t¹ will also be lifted at
the same time. The latches will remain in their elevated position as long as the
lever N¹ remains turned outwards, that is as long as the worm is engaged with
the worm-gear . The worm is supported by a spindle, c', passing through an
eccentric sleeve w¹, Fig. 12, arranged to turn in the arm projecting outward from
the head I. The eccentric, sleeve wol is fastened to the lever N¹ and turns with it,
so that when the lever is swung outwards, the spindle r¹ and the worm, are
lowered so that the latter engages with the worm gear u². The rotation of the
worm then drives the wood-holder in the standard F and this movement is trans-
mitted to the wood-holder in the other standard by the shaft N and the gearing
already described. y' is a lever provided with a spring and pivotted to the
lever N, by which the pin n' is withdrawn from a hole in the arm, when it is
desired to engage the worm-gear. The pin n¹ serves to prevent the accidental
engagement of the worm and worm-gear. The spindle a is provided with a collar
at its end.
In order to provide for driving the worm 12, while at the same time permitting
the adjustment of the wood-holders relatively to the cutter head, and the reciproca-
tion of the carriage, I make use of the upright shaft T' and the telescoping shaft U',
provided with universal joints V1 V2. 'The shaft T' is driven from the shaft T by
the bevel-gears, and at its upper end it transmits motion, through the bevel-
gears to one member of the universal joint V₁. One part of the telescoping
shaft U is splined and slides within the other during the reciprocating movement
of the carriage, or, if desired, the shaft may be easily detached and taken off in
case the machine is to be used for some time on polygonal shapes. The bevels at
the upper end of the shaft T' are supported by a suitable bracket. The ratchet on
the shaft M permits it to revolve when the worm is used to rotate the wood-holders,
without interfering with the gear Cor the rack B. The pinions as and ratchets rri
turn freely on the shaft N when the wood-holders and gears L L' are revolved in
turning cylindrical shapes,-the dogs being held away from the ratchets by the
springs ພ.
The mechanism for imparting a suitable intermittent rotary motion to the wood-
holders consists essentially of the pivotted adjustable cams A2 A³, Figs. 6, 7 and 8,
operating the sliding rack B2, the gear C, and pinion D2, Fig. 3, on the shaft M.
As already mentioned, the shaft M is geared at its ends to the wood-holders, so that
the latter revolve simultaneously. As the carriage reciprocates, the cams A* A³
cause the rack B to slide upwards and this motion is transmitted to the shaft M
and the wood-holders, by the gear C and pinion D2, Fig. 3, the return movement
being secured by the spring E2, Fig. 1. which is connected with the rack by a
swinging arm G and link H. The upward movement of the rack disengages the
latches from the notches in the rings of the wood-holders, by causing the cam
or lug o', Fig. 6, which turns on the shaft M, to come in contact with the arm P
on the shaft N carrying the latches. The return or downward movement of the
rack turns the shaft M so as to rotate the wood-holders. The cam o' and the
pinion D³ move together, a ratchet being interposed between them and the shaft M.
As the cam o returns to the position shown by the full lines in Fig. 6, the springs w
force the latches down into contact with the rings, so that their points enter those
notches in the rings which are next brought opposite to them by the movement of.
the wood-holders, the movement of the rack B is indicated by the full and dotted
lines in Fig. 6. The cains A' A³ serve to raise the rack B2 auring the latter part
of the movement of the carriage in each direction, so as to give the wood a partial
rotation twice during each complete reciprocation, the cutter C consequently

page_text: acting on the wood as the latter is presented to it from either direction, the lower
end of the rack B2 is provided with the rollers a² a³, which project outwards from it
in opposite directions. The cam A' is pivotted on an arm or stud projecting
inward from the side frame A, and the cam A' is pivotted on a similar stud d.
The free ends of the cams project inwards, resting on an arm which sustains
them. The cam A³ is provided with an inwardly projecting inclined flange e³,
arranged in line with the roller a² so as to come in contact therewith as the latter
is carried along by the carriage. The cam A' is provided with a corresponding
projecting flange, 12, arranged in line with the roller a³, but inclined in the opposite
direction from the flange. The flange f' is made adjustable lengthways by being
attached to the arm of the cam by the slotted plate g', Fig. 8, and the screw /.
The flange eis in a corresponding way made adjustable by a plate and the screw .
While the carriage is travelling from left to right in Fig. 6, the roller a³ comes
against the lower side of the flange e² and lifts the cam A2, as indicated by the full
lines in Fig. 6 and the roller a passes along the upper side of the flange * of the
cam A*
The rack B2 is thus lifted until the roller a³ passes beyond the flange, when
the rack falls, under the influence of the spring E, and, during the return
movement of the carriage, the roller passes under the flange 13, raising it as
indicated in Fig. 8, while the roller a travels up the flange of the cam A',
again raising the rack, but permitting it to fall as soon as the roller moves
beyond the upper end of the flange. It will thus be seen that the rack is
forced downward quickly at or near the end of each reciprocating movement of
the carriage, and that this movement of the rack operates to impart a partial
rotation to the wood-holders through the gear C³, the pinion D³, shaft M, and
gearing op, op. It will be also understood that it is necessary to turn the
wood-holders through a longer arc when the machine is dressing the lumber
square in section than when making hexagonal or octagonal shapes, and in order
to do this we arrange to give the rack B2 a variable amount of movement,
according to the form desired, for this purpose the rack B' is provided with an
adjustable stop, which limits the downward movement, and consequently the
distance which it can be raised by the inclined flanges e 1 of the cams A³ A³.
In cutting square work, the whole or nearly the whole of the inclined surfaces
of the cam-flanges is employed, while for polygonal shapes a portion only of
these surfaces will impart the requisite the amount of movement to the rack.
D', Fig. 6, represents the adjustable stop, which rises and falls with the rack,
and in its lowest position rests upon the upper end of the guide way I' in
which the rack travels,-a buffer E, of indiarubber, being interposed at this
point. F is a screw, arranged to turn in a projecting arm on the stop, and
threaded into the upper end of the rack. By means of the screw F, the position
of the rack may be adjusted so as to vary the relation of the rollers at the lower
end of the rack B2 with the cams A A³. A scale may be made on the rack at
any convenient point, as at G, Fig. 6, to indicate the position in which the rack
hould be set for working on different shapes.
A set-screw K, Figs. 1 and 6, is used, to secure the rack B2 to the part D',
after it has been adjusted to the proper relative position by the screw F.
9
By making the inclined flanges e27 of the cams A2 A3 adjustable lengthways of
the cams, I am enabled to vary the points at which the rack B' begins and ends
its upward travel relatively to the reciprocations of the carriage, by which I am
enabled to save time in the running of the machine by varying the length of the
reciprocation of the carriage,-which may be shortened for sticks of small
diameter.
In varying the distance of the wood-holders from the cutter, which is done by
turning the screws, m m³ by the cross shaft and bevels it, so as to adapt the
machine to turning or shaping lumber of different diameters, it may be necessary
to adjust the gear C, and this is provided for by supporting the gear on a stud E¹,
Figs. 1 and 6, which passes through a slotted opening in the standard F, and is
:

page_text: secured by a nut or bolt. By this means an adjustment is provided by which the
pinion D2 on the shaft M is kept in proper mesh with the gear C, whether the
wood-holders are set close to or at a distance from the cutter head.
The holes through the wood-holders are cylindrical except at their inner ends,
where the clamping devices are located.
The side frames A A' are cored, to secure lightness and strength.
The construction of the ratchet on the shaft M will be understood from the
sectional view, Fig. 13. P is a collar fastened on the shaft and having a series of
ratchet teeth formed in its surface in position to engage with the pawla, which
is arranged to slide in a hole or way in the projecting arm on the sleeve d². The
gear D is secured to one end of the sleeve and the cam o2, Fig. 6 to the other.
The sleeve turns the shaft in one direction, by means of the pawl, but the shaft
can revolve in the sleeve,-the teeth of the ratchet pushing the pawl outwards.
y is a spring which forces the pawl inward, and u³ a plug which holds the spring
in place. The ratchet P¹ has twenty-four teeth, so that the wood-holders can be
turned one-fourth, one-sixth, or one-eighth of a revolution, at each movement of
the rack B².
The spring E' which secures the return movement of the rack B', and operates
the wood-holders, is attached to the standard F, by the socket-piece, Fig. 1.
and the bracket w. is a shaft which extends entirely through the spring being
arranged to turn in the bracket and socket piece, and provided with the ratchet v
which has a hub to which the end of the spring is fastened.
The other end of the
spring is attached to a hub on the arm G, which is connected by the link H2 with
the adjustable stop D', as shown in Fig. 14, the arm G' turns freely on the shaft st.
A pawl, Fig. 1, pivotted on the socket piece 14, engages with the teeth of the
ratchet, the outer end of the shaft sis fitted for the application of a wrench and
it will thus be seen that by turning the shaft, the tension of the spring may be
adjusted, the pawl engaging with the teeth of the ratchet, and maintaining the
tension of the spring. As the rack B and the stop D' move upwards, the arm G²
turns on the shafts, compressing the spring, the power of which secures a quick
return movement of the rack, which is cushioned by the buffer Et interposed
between the lower end of the stop and the standard F.
The shaft which connects the screws m m' by which the heads I I¹ are raised
or lowered, is splined, and the bevel gear on it slides through it when the
standard F is adjusted to adapt the machine to long or short lumber. In a similar
manner the shaft M is splined to slide through the gear o. The latch t¹ and
pinion and ratchet s' are also adjustable lengthways of the shaft, N.
The cam o² is formed on a ring which is divided and clamped on the sleeve d', as
indicated at 4, Fig. 6, so that the cam can be adjusted to time its action on the
arm P to lift the latches.
It will be observed that by providing the rings 4, 6 and 8 with four, six and eight
notches respectively, I am enabled to adapt the machine to dressing square,
hexagonal and octagonal forms. The rings are conveniently formed in one piece
by placing the ring having four notches between the other two rings, in which case
the middle ring can be notched by planing through every other one of the notches
of the 8 notched ring.
My improved wood-working machine may be made of any suitable dimensions,
adapted to dressing ornamental forms of auy desired length or diameter, either
circular or polygonal as may be preferred.
The machine can also be used for dressing twelve-sided forms. Provision is
made for fastening the heads I l' in any position relative to the cutter in which
they may be set, by means of the bolts y, Fig. 12.
