A designates the main frame of the machine; it is of proper form and dimensions
to receive, sustain and accommodate the various mechanisms and operating devices,
and is provided near one end with an upright frame or housing A¹, to receive the
oscillatory-reciprocating cutting mechanisms.
The principal elements of the machine are the feeding mechanism B; the lower
or bottom facing mechanism C; the top dressing mechanism D; the edging
mechanisın E; and the oscillatory-reciprocating molding mechanism F.
As elements these mechanisins are present in the Patent before mentioned but their
construction and arrangement has been modified and improved.
The feeding devices (shown in Figures 2, 4, 6 and 8) are mounted upon an
independent frame G, supported at one end upon a cross bar a of the main frame,
the opposite end of said frame G being connected to the main frame in a manner
to permit of vertical adjustment, as by being provided with or connected to a cross-
bar g having adjusting or set screwз g engaging the main frame, whereby the inner
end of the frame carrying the entire feeding mechanism may be raised or lowered,
for a purpose to be described.

page_text: The feeding devices shown in the present embodiment, comprise a series of
independent pressure rollers I each mounted in a swinging frame 2 pivotally supported
at 3 in housings 4 rising from the sides of frame G. Each frame 2 is provided
with an adjusting screw 5 (see Figure 2) engaging a vertical post 6, the latter slotted
or provided with a bearing to receive a bar 7. The bar 7 connects two of the
posts 6 and is acted upon at or near its centre by a lever 8, pivoted, as at 9
(Figure 8) to one side piece of frame G; while the free end of said lever is engaged
by a link 10 connected to a weighted lever 11, (Fig. 2).
By these means the height of the pressure rollers can be adjusted, and the weights
caused to hold the rollers down upon the material passing beneath them.
Mounted in bearings in the sides of the frame G, beneath the plane of the
rollers 1, are two shafts 12, one in front and the other in rear of the series of
rollers, and each shaft is furnished with a driving gear 13 (Figs. 4 and 6) and
sprocket wheel 14 (Fig. 8) the latter provided with staggered teeth, as shown, and
the teeth of the wheel 14 on one shaft reversed in position as compared with the
teeth of the wheel on the other shaft.
Extending between and embracing the sprocket wheels 14, is an endless belt or
chain 15, composed of a series of independent links provided with studs or projections
on one face or edge and articulated together upon rods, after the manner of a drive
chain.
The upper portion of the endless chain passes over and rests upon a frame or
table 16, adjustably and detachably secured between the side plates of frame G
beneath rollers 1 and extending between the sprocket wheels 14.
The two shafts 12 are provided with driving gears, and the sprocket wheels 14,
carrying the endless chain. are arranged in reversed position in order that the chain
may be driven in either direction, forwards to carry the board beneath the rollers
towards the cutting mechanisms, or backwards to withdraw the board from the
machine.
The frame or table 16 is made adjustable both longitudinally and vertically upon
frame G, the vertical adjustment being effected by screws 17, and the table held
firmly in adjusted position by clamping bolts 18 passing through slots in the table
(see Figure 8) and in the frame G (see Figure 2).
As indicated in Figure 2 provision is made for adjusting one or both shafts 12
to take up slack in the chain, or to loosen the latter, said means being represented
by the set screw engaging the bearing of the shaft.
All of the parts thus far described, with the exception of the weighted levers 11,
are mounted upon the frame G, hence are not disturbed when said frame is moved
for adjustment, but are carried bodily, and this feature of the invention is not
limited to the use of a chain feed but is also applicable to other forms. The devices
for communicating motion to the feed mechanism are mounted upon the main frame
and connected at will to the feed mechanism as follows: 18 is the main driving
shaft provided with a pulley 19 receiving motion from the motor, and 20 is a pulley
on said shaft from which motion is transmitted through belt 21 and pulley 22 to a
shaft 23 (see Figures 1 and 7), the latter carrying a pulley 24, from which a belt
extends to pulley 25 on shaft 26 (Figures 2, 4, 6, 8 and 13). The shaft 26 carries
a worm 27 in gear with a worm wheel 28 on shaft 29, and upon the latter are
mounted two bevel pinions 30 connected to rotate with the shaft but capable of
longitudinal motion thereon, said pinions being supported in boxes 31 connected by
bar 32 and adapted to reciprocate in guides 33, on the side of frame G.
A lever 34 engaging bar 32 is arranged for shifting the boxes 31, and with them
the pinions 30, longitudinally of shaft 29, to bring one of the said pinions in engage-
ment with the wheel 13 on one of the shafts 12 of the feed mechanism. The
pinions 30 are located on relatively opposite sides of the two wheels 13 and at such
distance apart that when one is brought into engagement with its wheel 13 the other
will be carried and held out of gear, moreover the one pinion will operate to drive
the feed mechanism forward and the other in the reverse direction, and when
the lever is shifted to an intermediate position, both pinions will be held out of

page_text: ngagement and the feed motion will be interrupted. An idle pulley 35 is mounted
on shaft 23, and a shipper 36 is arranged to throw the belt 21 from pulley 35 to
pulley 22, and vice versa, said shipper being actuated by handles 36ª secured to a
od 37 mounted in bearings on the side of the frame A that it can readily be
operated from different positions.
↑
Immediately in advance of the feeding mechanism is arranged the bottom or under
facing cutting mechanism C (Figures 1, 3, 5 and 7). It comprises a cutter-head 40
mounted upon a shaft or arbor 41, the latter supported in bearings in a frame 42
movable laterally of the frame A on guides a formed on or in one of the cross-pieces
of the main frame. The shaft 41 carries a pulley 43, receiving motion from a belt 44.
The frame carrying the under cutter is made movable laterally of the machine so that
it can readily be withdrawn by the manipulation of suitable devices for the purposes,
such for example as the rack and pinion 45.
This cutting mechanism is provided with a novel form or arrangement of pressure
devices for maintaining the board or other material firmly down upon the table in
proper relation to the axis of the cutter-head.
The frame A is formed or provided with two standards A³ from which project arms
or overhanging extensions a³, each furnished on its inner side with vertical guides or
ways to receive a cross-bar 46, the latter being provided with devices (such as
screws 47 connected and operated through a shaft and gearing) whereby both ends of
the bar can readily be adjusted.
Upon the cross-bar 46 is mounted a frame or carriage 48, capable of move-
ment longitudinally of the bar, and laterally of the machine, a set screw 49 or
equivalent means being provided for holding the carriage 48 in adjusted position upon
the bar.
The laterally adjustable carriage 48 is provided with two independent vertically
movable presser bars or rollers 50, one in front and the other in rear of the cutter-
head 40, and each presser bar or roller is furnished with a spring 51 or equivalent
yielding pressure device for holding it down upon the material. Although not essential,
it is preferable that the operating face of the presser bar be provided with a roller or
rollers 50 as shown, and in the illustration said rollers are journaled in bars or
supporting frames 52 moving in vertical guides in carriage 48, and they are held down
by springs 51, each spring engaging a bearing upon the frame 52, on opposite sides
of the centre, and provided with an adjusting screw 53.
Beneath one of the presser bars or rolls 50 is a fixed support or portion of the
table, while the other or front bar or roll 50 cooperates with the inner end of the table
forming part of or connected to the vertically adjustable frame G of the feed
mechanism.
Among other advantages possessed by this arrangement of pressure devices may be
mentioned the following:The cutter-head 40 is located beneath the general level of
the table in advance of all the other cutting devices, and is designed to reduce the
lower face of the board or other material to a level surface thus forming the base from
which the movements of the top dressing cutters are calculated.
The fixed portion of the table in advance of cutter-head 40 is arranged with its top
surface at or about a tangent to the circle traversed by the edges of the bits on the
cutter-head, so that the board, after passing the cutter-head, rests level on the surface
of the table.
The roller or presser bar above this fixed portion of the table serves to hold the rear
end of the board after it passes the first roller or presser bar, and the latter being
independent of the second, operates to sustain the entering end of the next succeeding
board, whereby boards differing in thickness may be fed, one immediately succeeding
the other, and both held firmly down upon the bed or table while being operated upon
by the cutters.
By arranging the front presser bar or roller in a position to cooperate with the
inner end of the frame C, the depth of the cut or amount of surface covered by the
cutter-head 40 can be varied and determined by a single adjustment of the inner end
of the frame carrying the feeding mechanism, for, by so doing, the board will be

page_text: caused to approach the cutter-head with its lower face moving in a line intersecting
the circular path of the cutters to greater or lesser degree, and, as the board is moved
over the cutter, its dressed surface will pass onto and receive support from the fixed
portion of the table. The frame carrying the presser bars or rollers is arranged to be
moved laterally of the machine, upon bar 46, in order that its central portion may
be brought opposite the middle of the board passing through the machine, thereby
ensuring a constant and equal pressure upon the surface of the plank, and preventing
it from rising under the action of the cutters, otherwise, when a narrow board or
plank was passed through the machine under one end of the roller or presser bar, the
latter would be tilted in its guides or bearings holding the board along one edge but
permitting the opposite edge to rise and thus defeat the object had in view, which is
the dressing down of the lower face to a uniform plane.
Thus, it will be seen, provision is made for adjusting the presser bars or rollers
laterally and centrally of the plank ; for firmly supporting the rear end of one plank
and the entering end of another even when said planks are of different thickness; and
for adjusting the depth of cut without changing the presser bars or rollers or the
cutter-head; all of which improvements are applicable to other forms of planing and
molding machines than the one herein shown and described and render it practicable
to employ a lower surface cutter at the beginning of the operations performed.
A spout or conductor 54 may be arranged beneath the cutter-head 40 as shown in
Figure 7 for conducting away the chips.
Beyond the lower surface dresser is arranged an upper or top dressing mechanism D,
the same consisting of an arbor or shaft 55 carrying a driving pulley 56 and cutter-
head 57, the whole mounted in a frame 58 provided with bearings 59 and supported,
for vertical adjustment in guides formed in or upon the standards A³. The frame 58
carries a cross-bar or support 60 to which are pivoted arms or levers 61 carrying
chip-breakers 62 and weights 63, and said cross-bar 60 also carries vertically
adjustable shoes or presser bars 64 which are set to bear upon the upper face
of the board or plank after leaving the upper cutter, for holding it firmly upon
the bed..
The upper facing cutter is driven by the same belt 44 as gives motion to the lower
cutter-head 40, said belt running from a pulley 65, on main drive-shaft 18, on pulley 55
of upper cutter, down and back around pulley 43 of lower cutter, around an
adjustable tightener pulley 66 and back to driving pulley 65, as shown more clearly in
Figures 3 and 4 and 5 and 6.
As will be readily understood by those skilled in the art, the devices thus far
described, besides inaugurating and maintaining the feed of the material through the
machine, dress down the opposite faces of the boards and reduce it to uniform
thickness, preparatory to the action of the former cutters.
The next in order is the side cutting or edging mechanisms E. Although located
and arranged for operation on opposite sides of the table over which the material is
conducted through the machine, the two edging mechanisms are substantially the
same in general construction, hence a description of one will answer for both.
The cutter-head 70 is mounted upon the upper end of a shaft or arbor 71 supported
in bearings in a frame 72, the latter guided to reciprocate on ways formed on one of
the cross-pieces of the main frame.
A slide 73 also reciprocating on the cross-piece a² of the frame, is adjustably con-
nected to the arbor frame 72 through a screw 74, the outer end of the latter being
loosely supported in a bearing 75 on the main frame, to bring the several adjusting
screws on the same side of the machine. The slide 73 carries a roller 76 which is
engaged by a cam 77 on a counter shaft 78, said shaft being mounted in bearings on
the side of the frame and connected with a shaft 79 through gears 80.
The two cams 77 for the edge cutters are mounted upon the same shaft 78; and by
their form control the movements of the cutters in one direction, and the shape to be
given the edges of the board, the reverse movements of the arbor frame 72 being
effected by volute springs 81 connected at one end to a link 82 on slide 73, and at the
opposite end to a ratcheted adjusting device 83 on the main frame (see Figures 7

page_text: and 11).
Ine arbor frame 12 also carries a chip breaker 64 of the usual or any
approved construction, the one shown being pivotally supported upon an axis coincident
with that of the arbor, and held to place by a spring 85; and a spout 86 is provided
to conduct the chips from the cutters.
When it is desired to throw the side cutters or edges out of action, the cams 77
may be removed; and, when straight edges are to be formed, the slides 73 may
be secured in position by set screws 87, and thus made the basis for the adjustment
of the arbor frames through the medium of the screws 74.
Suitable shoes 88, and 89 are adjustably secured to an arch piece at of the main
frame, to hold the plank down while passing the edging cutters. The shoes 89
may be made to extend nearly to the first oscillatory-reciprocating cutter, in which
case their outer ends may be sustained against vertical displacement by adjustable
blocks 90 supported upon an overhanging frame or goose-neck 91, and provided with
set screws bearing upon said shoes.
The shaft 79 which transmits motion to the cams governing the edge cutters,
and, also, the cams or eccentrics of the oscillatory-reciprocating cutting mechanism,
derives its motion indirectly from the main driving shaft 18, through a series
of adjustable change gears 92 (Figures 6 and 15) connecting shafts 79 and 29,
the latter being driven from the main shaft 18ª as hereinbefore explained.
The arbors 71 carrying the edge cutters are driven by belts 93 from a drum or
pulley 94 on main drive shaft 18", said belts being given a quarter turn and
supported upon idler 95.
The last operating mechanism F of the system here illustrated is that for controlling
the movements of the oscillatory-reciprocating cutter-heads. Two only of these are
shown, but a greater or lesser number may be employed if desired, and as they are
practically duplicates, although occupying relatively reversed positions, a description
of one will answer for both.
The frame or housing A' is composed of uprights at the sides of the main frame,
and cross pieces a uniting said uprights and connected by one or more braces a³,
forming a rigid frame-work or arch above the table A4, which latter is detachably
mounted upon the cross-pieces of the main frame, as indicated in Figures 7, 9
and 10.
In addition to the cross-pieces a³, the uprights may be further braced and the frame
strengthened by a brace a' in which adjustable shoes or presses 96 may be secured
for holding the board down upon the table while being operated upon; and at the
rear end of the table A* other adjustable shoes 97 may be arranged, to hold the board
down after leaving the shoes 96.
The table beneath the oscillatory-reciprocating cutter, as well as that of the feeding
mechanism, is provided with undercut grooves or equivalent means for adjustably
securing, guiding strips 98 and 99 in position, it being the intention that one of
said guides 98 shall be set or fixed in adjustable position, and the other 99, moved
laterally, to accommodate various widths of boards operated upon, and in order to
facilitate the adjustment of the strip 99, and, at the same time, permit of a limited
amount of lateral motion, should the board vary slightly in width and have a
tendency to jam in the guides, a screw 100 is threaded through a nut attached to
guide strip 99, its inner end passing through a guide on the fixed strip 98 and bearing
a collar 101 or similar devices between which and the strip 98 is interposed a
spring 102 (see Figure 6) tending to hold the guide in adjusted position but
permitting it to yield laterally should it be necessary.
The outer face of each cross-piece a³ is provided with guides or ways 103 for the
reception of a travelling slide or carriage 104, the latter connected, through
screw 105 or equivalent adjusting device with a smaller supplemental slide 106, also
travelling in ways on the cross-piece as, parallel with the slide 104.
This slide or carriage 104 is formed or provided with a vertical tubular guide or
socket 107 for the reception and accommodation of the arbor frame carrying the
oscillatory reciprocating cutter-head.
This arbor frame 109 is detachably and adjustably secured to the lower end of a

page_text: post 110 fitted to turn within the socket 108, and provided with a reduced portion or
stem 111 passing centrally through a sleeve 112 the latter occupying the upper
portion of the socket. The post and sleeve are adapted to rotate or turn together in
the socket, but the post is movable longitudinally within the sleeve, by suitable
means acting upon or through the stem 111, and can, when desired, be clamped in
adjusted position by a pinching bolt 113 (see Figure 7). The post 110 and
sleeve 112 constitute what may be termed a telescopic support or frame for the
cutter, as one moves in or upon the other to lengthen the frame, and both oscillate
together in the socket. The lower portion of the socket, where it engages
the post 110, may be slotted longitudinally and provided with a
for adjusting the diameter of the socket to compensate for wear and preserve a
snug fit.
screw 114
The arbor frame may conveniently be connected to the post 110 by providing it with
an undercut rib fitted between guides or ways 115 on the end of the post 110,
the latter being slotted and provided with a pinch screw or screws 116 for
clamping the ways onto the rib and securely fastening the arbor frame in
adjusted position.
The arbor frame 109 is provided with bearings for the arbor 117 carrying the
cutter-head 118 and pulley 119, the cutter-head being arranged between the bearings
and in line with the post 110.
It will be observed that provision is thus made for adjusting the arbor frame
laterally of the post by shifting it on the latter; for adjusting the distance of the
cutter from the bed-plate or table, by moving the post longitudinally within the socket
and sleeve; for oscillating the cutter-head about an axis coincident with the axis of
the socket, by rotating or oscillating the sleeve and post within the socket; and for
reciprocating or moving the cutter-head and its supports laterally of the table and
across the line of movement of the board, by shifting the carriage or slide to which
the socket is secured.
The cutter-head occupies a position immediately below and in line with the
post 110, and the latter is supported by the socket against lateral motion or springing;
while the socket itself is rigidly secured to the slide or carriage 104, which is in turn
sustained and guided upon a rigid frame extending over the bed-plate or table,
whereby springing of the parts while the cutters are in action is almost if not entirely
prevented, and all the movements necessary to produce the most elaborate figures or
designs can readily be effected.
The oscillatory-reciprocating motions of the cutter-head are effected by the
simultaneous, successive or separate movements communicated to the slide or
carriage 104 and the post 110, and these movements are produced and governed by
suitable actuating devices such as will now be described.
The reciprocating movements of the slide or carriage 104 are transmitted through the
supplemental slide 106, in order that the position of slide 104 may be readily adjusted
and the cutter-head properly located above the board, by means of the adjusting
screw 105, without changing the actuating devices.
On the side of the upright A¹ is pivoted a bell crank lever 120, of which one
arm 121 bears against the slide 100, while the other arm 122 engages a rod or
pitman 123 whose lower end carries a yoke or bearing block 124 resting. upon a cam
or eccentric 125.
In order to accommodate the rocking movement of the lever 120, a block 126
having a rounded pin resting in a socket in the arm 121 may be interposed between
the latter and the slide 106; and the end of pitman 123 may, in like manner, be
rounded and fitted to a concave seat in arm 122. The carriage 104 is retracted, and
the yoke 124 held at all times pressed firmly against the surface of the cam 125 so
as to follow the latter, by a yielding pressure device, such as a coiled spring 127
mounted on the inner side of the cross piece a³, one end of said spring being con-
nected to an adjusting ratchet 128, and the other or outer end bearing against a
link 129 pivoted to a slide 130, the latter movable in guides on the cross-
piece a and impinging against a lug 131 on the carriage 104, said lug being

page_text: projected through a slot or opening in the cross-piece a as indicated in
Figure 10.
The oscillatory movements of the post 110 carrying the arbor frame are effected
by automatic actuating devices connected to the sleeve 112.
This sleeve is provided with a toothed segment 132 (Figure 5) with which
co-operates a rack-bar 133 mounted to reciprocate in guides upon the slide or
carriage 104. The inner end of this rack-bar is formed or provided with a projecting
portion carrying a set screw 134 whose point is furnished with a shoe or washer 135
resting against a bar 136 extending parallel with the ways upon which carriage 104
reciprocates.
This bar 136 stands parallel with a shaft 137 and is rigidly secured thereto by
arms 138; said shaft is mounted in bearings in the uprights of frame A¹, and is
provided at one end, with an arm or lever 139 whose outer end is provided with a
socket to receive a rod or pitman 140 pivotally connected at its lower end to a yoke
or saddle 141 resting in contact with the surface of a cam or eccentric 142.
The sleeve 112 is retracted, and the yoke 141 held constantly against the surface of
cam 142, by a spring 143, one end of which is secured to the carriage 104, as at 144,
while the opposite or inner end is fastened to a shaft carrying a ratchet wheel 145, the
latter engaging a pawl on pivoted har 146 whose outer end is connected by a link 147
to an arm 148 on the sleeve 112. The ratchet and pawl connection facilitates
adjusting the tension of the spring.
From the description given it will be readily understood how the various move-
ments produced by the rotation of the cams are communicated to the carriage 104,
and to the post 110 carrying the arbor frame.
As the slide or carriage 104 is reciprocated, under the influence of and in
accordance with the form and dimensions of its controlling cam 125, it carries the
arbor frame and its attachments bodily across the machine, above the table and in a
direction transverse to the direction in which the board is advancing under the action
of the feeding mechanism. While the arbor frame is thus carried back and forth
across the machine, it is caused to oscillate about a centre coincident with the axis of
the post 110 and intersecting the cutter-head, said oscillating motions being at all
times controlled by the cam 142, acting through intermediate transmitting devices
upon the sleeve. 112. The connection between the cam 142 and sleeve 112 is
maintained during the reciprocating movements of the carriage 104, by means of the
sliding connection between the rack-bar 133 and the bar 136, the former carried by
the reciprocating carriage, and the latter mounted upon the shaft 137 with its face
substantially parallel with the line of movement of the carriage.
Each cam 125 and 142 is independently adjustable and all of them are mounted
upon and secured to a prolongation of the same shaft, 79, that drives the cams
controlling the edging cutters, whereby a single shaft, located on one side of the
machine and deriving motion from the main drive shaft, is caused to effect and control
the various motions given the several cutter heads.
Provision is made for rotating the cutter-head during its oscillatory-reciprocating
motions, for accommodating said movements and for adjusting the tension of the belts
and starting and stopping said cutters, as follows:-
A shaft 150 carrying a pulley 151 and a drum or wide.face pulley 152 is mounted
in bearings in arais 153 secured to a rod or shaft 154 which latter is pivotally
supported in the main frame. The pulley 151 is connected by a belt 155 with a
driving pulley 156 on main drive shaft 18, while the pulley 152 is connected by a
belt 157 with the pulley 119 on arbor of cutter-head 118.
The arms 153 are so arranged that the weight of the shaft 150 and its vibrating
frame will be sustained, principally, by the belt 157, keeping the latter taut and at the
same time permitting the shaft 150 to rise and fall to accommodate the various
movements of the arbor carrying the cutter-head.
The tension of the belt 157 is adjusted and regulated by means of adjustable
counter balance weights 158 applied to arms 159 secured to shaft 154 and acting in
opposition to the weight of shaft 150 and its connections.

page_text: By turning the shaft or rod 154 so as to elevate the arms carrying shaft 150, the
tension on belt 157 can be relieved and the cutter-head thrown out of operation.
The movement of the arbor frame across the machine is compensated for by the
travelling of the belt 157 upon the drum 152, and it is mainly to accommodate the
lateral or oscillatory motion of the arbor frame that it becomes necessary to provide a
vertical movement of the shaft 150.
Instead of relying upon the belt to raise and lower the shaft 150, this operation
may be automatically performed and the arbor of the cutter-head relieved of the
strain incident thereto. With this end in view the shaft 137, through which the
oscillatory movements of the arbor frame are produced, is provided with an arm 160
whose lower end is connected by a link with a lever 161 pivoted at 162 on the main
frame, and provided at its lower end with an arc shaped slot 163 of short radius.
An arm 164, loose on rod 154, carries a pin 165 resting in slot 165, and said arm is
also provided with another pin 166, (or prolongation of pin 165) passing through a
slot 167 in a lever 168 secured to the rod 154, with a hand wheel or nut 169 threaded
onto the pin 166 for clamping and holding the lever 168 and arm 164 securely
together in adjusted position.
To set the shaft 150, so that its pulley 152 will bear with the required pressure
upon belt 157, the nut 169 is loosened, and, by means of lever 168, the rod 154 is
turned until the belt is taut, after which the nut on pin 166 is tightened to lock the
lever 168 to the arm 164. A portion of the weight of shaft 150 and its connections
is now borne by the pin 165 in slot 163, and as the lever 161 vibrates in unison with
the arbor frame it will automatically raise and lower the shaft 150, and thus compensate
for the movement of the arbor laterally of the shaft.
As hereinbefore stated the post 110, carrying the oscillating reciprocating cutter-
head, is adapted for longitudinal movement, to cause the cutter to approach or recede
from the bed-plate, by the application of suitable actuating devices. The movement
thus given may be automatically effected, as when it is desired to vary the longitudinal
contour of the plank or of the figures formed thereon, or it may be simply for
adjustment, to determine the height at which the cutter-head shall stand.
One forin of adjusting mechanism is illustrated in Figures 1, 3, 5, 7, 9 and 10
wherein the upper end of spindle 111 is connected by a swivel joint with a bar 170
through which is threaded an adjusting screw 171 supported against longitudinal
movement by a frame 172. The spindle is free to turn in the bar 170, and the latter
carries an index pointer co-operating with a fixed scale, to indicate the movement or
position of the arbor. By rotating the screw 171, the bar 170 is raised or lowered,
and the post 110 shifted longitudinally in the socket. The screw is mounted upon the
sliding carriage 104 and partakes of its movements.
The post can be automatically actuated, as well as adjusted in a longitudinal
direction, by mounting the support 172 carrying the adjusting screw 171 in vertical
guides 175 on top the carriage 104 (see Figures 16 and 17) and providing said
support with rack teeth engaging a pinion 181 on a shaft 176 supported in bearings
on the frame A'. The support 172 is held, under yielding pressure, by a spring 177
or equivalent device, and is actuated in the opposite direction by a cam or eccentric 178
on shaft 79 acting through pitman 179 and lever 180, the latter secured to
shaft 176. The pinion is splined or otherwise connected to its shaft 176 in a
manner to cause the two to turn together and at the same time permit the pinion to
move freely lengthwise of the shaft as the carriage is reciprocated.
As hereinbefore stated, the cams 125, 142 and 178 are removably secured to the
shaft 79 (the latter is preferably constructed in two or more sections connected by
couplings 190 so that each section can be removed or adjusted without disturbing the
other sections) to facilitate the application of cams of different forms and dimensions,
and they are preferably made separately adjustable radially of the shaft so that the
degree of eccentricity can be varied to regulate and determine the throw of the push
rods and the movements of the carriage and post.
A convenient arrangement is shown in Figures 18 and 19. The shaft 79 is
furnished with a head or collar 191 against which the several cams are clamped by a

page_text: nut 192. Cam 125 next the collar is composed of two parts, a fixed block or
section 193 secured to the shaft against rotation thereon by a set screw or equivalent
means; and the cam proper 194 provided with an elongated opening for the
accommodation of the shaft and guides or ways engaging guiding surfaces on the
side of block 193, an adjusting screw 195 serving to connect the two sections and
effect the adjustment of the cam section 194 upon the block 193 radially of the shaft.
An index 196 is formed upon or attached to one section and a mark or pointer on the
other to indicate the degree of adjustment.
The several cams are of similar construction to the one described, with the exception
that cams 125 and 142, which are set to move at right angles, are each provided with
a guide 198 engaging ways formed at right angles in the opposite faces of a collar or
plate 199, the latter mounted upon the shaft between said cams, and serving to prevent
accidental turning of either cam separately.
When the automatic attachment for reciprocating the post 110 longitudinally is not
employed, the cam 178 may be removed, and when it is desired to use the machine as
a straight molder or planer, or for other reasons the reciprocating or oscillating move-
ments are not required one or all of the cams can be adjusted to a position concentric
with its driving shaft 79, so that no movement will be produced by the rotation of the
cam.
