Improvements in Wood-working Machines.
We, HENRY WARD MORGAN, of Number 46 Platt Street, in the City of
Rochester, County of Monroe, and State of New York, Manufacturer, and
CHARLES MORTGRIDGE LORING, of Number 204 Washington Street, in the
City of Minneapolis, County of Hennepin, and State of Minnesota, Manufacturer,
both in the United States of America, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to improvements in wood-working or grooving machines
particularly designed for cutting the grooves in the ends of boards or shooks for
forming boxes; and to this end it consists, essentially, in a frame, opposite cutter-
head bearings mounted on the frame, a support secured to one of said bearings for
supporting the bottom edges of the boards, a carriage movable lengthwise of said
support and provided with opposite heads or bars, clamping jaws connected to
said carriage heads or bars and movable laterally thereon for approximating their
adjacent faces and movable lengthwise of said support for feeding the boards across
the adjacent faces of the cutter-beads. The invention furthermore consists in the
detail construction and arrangement of the parts, all as hereinafter more particularly
described and pointed out in the claims.
In describing this invention, reference is had to the accompanying drawing,

The frame A may be of any desirable form, size, and construction, and is formed
with standards or legs a, a crosswise guide a¹. Fig. 4, and a lengthwise guide a².
The guide a consists of separated horizontal shoulders a³ ³, separated upright
shoulders aa at the outer edges of the shoulders a³ a³, and gibs or top
shoulders as a arranged above and projecting beyond the shoulders a² a². The
guide a consists of lengthwise ribs or shoulders a a arranged along the tops of
the longitudinal sides of the frame above the shoulders a³ a³.
Movable within the guides a¹ is a carriage B formed with lateral shoulders bb
interposed between the shoulders a³ a³ aa of the guide a. The feeding mechanism
for the carriage B consists of a driving shaft or spindle C supported in a bracket A
projecting from the left-hand end of the frame A; a shaft (arranged lengthwise
of the front face of the frame A beneath the guide a, and journalled in
bearings AA on the front face of said frame, bevel-pinions CC, bevel-gear
wheels (upon the driving shaft or spindle C and shaft C' for connecting said
driving shaft or spindle and shaft, and the pinion C fixed upon the shaft C' and
engaged with rack teeth upon the under face of the carriage B.
The gear wheel C, as shown at Figure 17, is loose upon the shaft C¹, and is
formed with a hub C, which projects from one of its faces and is formed with a
shoulder C; and the gear wheel C₁ revolves loosely upon the hub C" on the
inside of the shoulder C. The gear wheels C C are formed at their outer faces
with the respective clutch sections C7 C8 for engaging clutch sections C³ C
fixed upon the left-hand end of the shaft C', which is movable lengthwise in its
bearings A2 A2 for alternately engaging the clutch sections C7 C° and C8 C.
When, as illustrated at Figure 1, the clutch section C8 is engaged with the
clutch section C, the pinion C³, which revolves in the direction indicated by
arrow 1 at Figures 1 and 2, is engaged with the gear wheel C, and drives the
shaft C in the direction shown by arrow 2 at Figures 1 and 2, thus feeding the
carriage B to the rear of the frame A, owing to the engagement of the pinion C
with the rack teeth upon the carriage. During this engagement of the pinion C
and the gear wheel C the gear wheel C on the shaft C, although engaged with
the pinion on the driving shaft or spindle C, revolves loosely on the hub ("o
the gear wheel (³.

page_text: As soon as the shaft C' is moved lengthwise, so as to engage the clutch section
with the clutch section C' on the gear wheel C and to disengage the clutch
section C from the clutch section C8, the shaft C' is, as is evident to one skilled
in the art, revolved in a reverse direction for feeding the carriage B forwardly.
These clutch sections C8 C1 and C' C' are so relatively arranged that one pair
of said clutch sections may be entirely disengaged without the engagement of the
other pair in order that both gear wheels C C may be revolved loosely on the
shaft C by the pinions C2 C3 without affecting the revolution of the shaft C. It
is evident, however, that, as the shaft C' is moved lengthwisely in either direction
from its position assumed when neither pair of the clutch sections is in engagement,
one pair thereof is brought into engagement, and the shaft C' is then revolved
either forwardly or backwardly.
The driving shaft or spindle C may be revolved by any suitable construction of
power transmitting mechanism, here shown as a link belt c passed over the sprocket
wheel cupon the driving shaft or spindle C and over the sprocket wheel c² upon a
spindle D, a belt C¹³ running over pulleys C C15 mounted respectively upon the
spindle D and a second spindle D' and a belt C passing over a pulley Cupon
the spindle D', and a pulley C" mounted upon the main driving shaft k. Upon
this shaft kare tight and loose pulleys C18 C1, to which power is transmitted by
any suitable construction of power transmitting mechanism, not necessary to herein
illustrate or describe.
As previously stated the shaft C¹ may assume such a position that the bevel gear
wheels C C revolve loosely thereon without effecting the revolution of said shaft,
and this invention is provided with a shifting device automatically operated by the
carriage B for forcing the shaft to said position when being revolved either in the
direction shown by arrows 2 at Figures 1 and 2 for feeding the carriage rearwardly,
or in the reverse direction for feeding the carriage forwardly.
This shifting device consists of a lever co pivoted at c to an arm A³ on the
frame A. and formed with an arm c" for engaging a pair of faces or pins e c* upon
the carriage B. The lever c is provided at one end with a lug e engaged with a
grooved collar co fixed upon the shaft C' and at its other end with a hand engaging
portion c³.
When the carriage is feeding rearwardly, owing to the engagement of the clutch
sections C C the parts of the shifting device for the feeding mechanism of the
carriage are in the position shown at Figure 1. As the carriage B reaches the
limit of its rearward movement, the front pin or face e engages the end of the arm c
and rocks said arm backwardly towards the frame A into a plane substantially
parallel with said frame A. and thereby swings the lever c upon its pivot, so as to
move the shaft C' lengthwise within its bearings A2 A2 a sufficient distance to
disengage the clutch sections C8 C10 without engaging the clutch sections C7 Cº.
The shaft C then stops its revolution and the. rearward feeding of the carriage B
is automatically checked.
When desired to feed the carriage forwardly the operator engages the outer end c³
of the lever and rocks said lever a greater distance than it was automatically
rocked by the engagement of the front pin or face c with the arme, thus engaging
the clutch sections CC. The shaft C₁ then revolves in a reverse direction from
that indicated by arrows 2 at Figures 1 and 2, and feeds the carriage forwardly
until the rear pin or face engages the end of the arm and automatically rocks
the lever in an opposite direction to that in which it was rocked by the engagc-
ment of the forward pin with the arm, and thereby disengages the clutch
When desired
sections C7 C³ for stopping the forward movement of said carriage.
to again feed the carriage rearwardly the operator rocks the lever to its position
shown at Figure 1, and engages the clutch sections CC0.
It is frequently desirable to feed the carriage B by hand, and accordingly the
right hand end of the shaft C' is provided with a hand engaging wheel or piece C²,
which may be readily engaged for rotating the shaft C' when in such position that
neither pair of the clutch sections C7 C° and C8 C" are engaged.

page_text: Movable along the guides a² upon opposite sides of the carriage B are bearings e e,
which are of any desirable form, size, and construction suitable for supporting the
shafts e e¹ of the cutter heads E E. The bearings ee are, as best seen at Figure 7,
formed with separated faces e² e2 bearing upon the top faces of the ribs as a of the
guide a², and are formed with longitudinal shoulders e³ ³ bearing against the under
faces of said ribs a® a*.
These bearings e e are moved towards and away from each other by a screw F,
which is arranged lengthwisely beneath the guide a² at the outside of the rear
wall of the frame A, and is journalled in bearings A* A* projecting from said rear
wall of the frame A. Formed at the rear sides of the bearings e e are depending
lugs et et having screw threaded apertures or eyes eo for receiving the screw F.
F is a hand piece or wheel provided upon the right-hand end of the screw F for
facilitating the rotation of said screw. The screw F is provided at its opposite ends
with right and left-hand threads, and consequently, as said screw is revolved by the
hand-piece F in either direction, the bearings e e are moved lengthwisely of the
guide a², and approximate or separate the cutter-heads E E, thereby adjusting
the distance between said cutter-heads to the length of the boards or shooks
interposed between the clamping jaws, presently described.
Contact of the operator with the cutter-heads is obviated by upright guard
walls ee provided upon the bearings e e and arranged in front of the cutter-
heads E E, and having their inner edges extending almost to the plane of the inner
face of the adjacent cutter-head.
As best seen at Figures 2, 11, and 20, the cutter-heads E E are formed of a
series of oppositely arranged circular saws E' fixed upon the shafts e¹ el, as by
splines ee, and provided with projecting teeth E2 having their front faces or
edges E³ of substantially the same thickness as the groove to be formed in the ends
of the boards or shooks.
Beneath the lower saw E' are one or more washers E, and above the upper
saw E¹ is a shoulder E' adjustable upon the shaft e¹ for firmly clamping the saws
in position.
At Figure 23 the cutter-heads are shown as operatively engaged with the
adjacent ends of an interposed board r of substantially the same size as either of
the longitudinal sides of the box R, shown at Figure 21. It is frequently
desired to provide a box S with a sliding cover S¹, as shown at Figure 22, and in
that case, the upper tenon s¹ at one end of the longitudinal sides ss of the box S
must be formed of greater width than the corresponding tenons at the opposite
end of the box sides. To effect this result the lower saw E' of the cutter-head for
grooving the ends to be provided with the wide tenons is removed, and a washer E
is substituted as shown at Figure 24.
To
The cutter heads E E are arranged vertically, and, as they revolve in practice
at rapid speed, there is great liability of the bearings e e becoming heated.
obviate this result the weight of the shafts e el is supported by ball bearings E' E'
composed of opposite sections E E fitting sockets EE in the bearings e e,
sections E" E fixed upon the shafts el el, and balls E2 interposed between said
sections. Instead of the ball bearings E E", any other desirable form and
construction of bearings may be used.
The boards or shooks are arranged edgewise between the cutter-heads E E with
their ends towards said cutter-heads, and are mounted upon the upper horizontal
faces of supports G G, which consist of rails secured at 9g to the bearings e e,
so as to be simultaneously moved towards and away from each other as said
bearings ee are approximated or separated. Each of the supports G G is pre-
ferably provided with a movable rail or bar G'arranged at the inner side of said
support and hinged at its opposite extremities to the upper ends of links G' G²
having their lower ends hinged to downwardly extending arms G³ G³ upon said
supports, Figs. 5 and 6. These movable rails are elevated or depressed by
aljusters G G secured to the forward ends of the supports G G and bearing
against the forward links G G2, and said rails are held in their adjusted position

page_text: by suitable clamps, which preferably consist of bolts forming the lower
hinge pins for the links G and nuts movable upon said bolts.
The longitudinal edges of the boards or shooks to be grooved are supported
directly upon the rails G¹ G', and said rails are readily adjusted up and down to
regulate the size of the tenon or groove upon the opposite extremities of the lower
edges of said boards or shooks, and are then firmly held in their adjusted position.
After the ends of the longitudinal sides for the boxes, shown at Figures 21 and 22,
have been grooved, as shown at Figures 23 and 24, the lower saw E' shown by
dotted lines at Figure 24, is replaced in position, and the adjustable rails G¹ G¹
are then adjusted upwardly to the positions shown at said Figures 23 and 24, where-
upon the boards for forming the end sides of said boxes are then placed upon the
supports G G¹ and grooved by the cutter-heads.
The bars or rails G¹ G¹ may be dispensed with, and, although said bars or
rails are preferably used, the essential supports for the lower edges of the box
shooks are the rails or supports G G. The supports or rails G G may be formed
integral with or adjustably secured to the bearings for the cutter-heads, providing
said supports or rails are rigid or fixed when the cutter-heads are in operation,
and the supports G G are not necessarily of the same length as the bars or
rails G G
Movable lengthwisely upon each of the supports G¹ is a pair of clamping
jaws H H. Figs. 5 and 6, which are formed with clamping faces h h at their
adjacent edges disposed in planes substantially parallel with the axes of the cutter-
heads E E. The lower edges of these jaws H H are formed with shoulders 'h¹
bearing upon the support or rail G and with grooves 2 for permitting the up
and down movement of the movable rail G₁ mounted upon said support.
Secured to the outer face of each of the jaws H are laterally extending
arms HH, which engage laterally extending arms B₁ B' upon the carriage B
for supporting the jaws in an upright position, and move lengthwise of said arms
as the supports G G are adjusted towards and away from each other.
As clearly seen at Figure 3 the rear clamping jaws H H are of substantially the
same height as the cutter-head E E in order that, when the carriage B is in its
forward position, as shown at Figure 1, the inner faces of the cutter-head may be
guarded, for preventing contact therewith of the operator or his clothing when
handling the boards or shooks. The forward clamping jaws H H are provided
with longitudinally adjustable inner face plates H2 H2, which are formed on their
outer faces with ribs H3 H³ movable in upright grooves H H in the adjacent
faces of said clamping jaws. These face plates are also formed with upright
slots H H for receiving clamping bolts He H6 secured to the forward clamping
jaws H H for clamping said face plates in position.
The arms B B upon the carriage B are formed upou heads or bars B2 B2, and
are adjustable towards and away from each other for simultaneously adjusting the
front and rear clamping jaws H H so as to force their adjacent faces h h against
the outer faces of the interposed boards or shooks. This adjustment of the
heads B2 B2 is effected by moving the front head towards the rear head by means
of a screw B³ arranged lengthwise of the carriage B with its opposite ends
supported in front and rear uprights B4 B upon the front and rear extremities
of said carriage.
Be is a hand-piece or wheel fixed upon a spindle B' journalled in the upper end
of the front upright B, and B8 is a gear fixed upon said spindle and meshing with
the
gear B upon the feeding screw B³, whereby, when the hand-piece B is rotated
in either direction, the screw B³ is simultaneously rotated.
B1 is a nut mounted upon the feeding screw B³ and guided lengthwise upon the
carriage B. The guide for the nut B preferably consists of a bar B having its
opposite ends supported upon the opposite extremities of the carriage B, and, as
clearly seen at Figure 9, the nut B is formed with a lengthwise guide-way or
groove B in one face for registering with the central portion of said bar B.
The front and rear heads B2 B2 are, respectively, fixed upon and preferably

page_text: formed integral with the nut B and the rear upright B' upon the carriage B, and
are each formed on their lower face with a lengthwise groove B13 in which are
movable upturned ribs H7 H7 upon the adjacent clamping jaws H H.
As the supports G G are moved towards and away from each other, as previously
described, the opposite clamping jaws H H movable upon said supports are also
moved laterally upon the arms of the heads B2 B2, as previously described, and,
during said movement, the ribs H' are moved lengthwisely within the grooves B1 B¹³
in the heads B2 B². Moreover, as the carriage B moves to and fro within its
guide a', the clamping jaws H II are moved simultaneously with said carriage
along the supports G G, and thereby move the ends of the interposed boards or
shooks across the cutter-heads E E, since the ribs H' formed upon said jaws inter-
lock with the grooves B13 upon the heads B2 B2, as clearly illustrated at Figure 8.
As the nut B is adjusted lengthwise of the carriage, it carries with it the front
clamping jaws interlocked with said head, and thereby efficiently clamps said jaws
against the adjacent faces of the boards or shooks.
In order to regulate the depth of the groove to be formed by the cutter-heads E E
one of the bearings e is provided with a gauge I, Figures 1, 2, 13, and 14, which
consists of a movable plate i, an adjuster, and a clamp 2.
The plate is formed with an inner face 3 disposed in a plane substantially
parallel with the line of movement of the carriage B, and its outer end is movable
in a guide in the bearing e, and is formed with a slot . The adjuster ¿¹ is
movable through an ear e upon the bearing e, and its inner end bears against the
adjacent face of the outer end of the plate i, and is formed with a nipple i³, which
enters an aperture 2º in the plate i, and serves to support said plate in its movement.
The adjuster is held in its adjusted position by nuts bearing against the
opposite faces of the ear. The fastener is passed through the slot in the
plate i, and one extremity is screw-threaded and engaged with a screw threaded
socket in the bearing e, and the other extremity is formed with a hand engaging
portion or shoulder bearing against the upper face of the plate i.
As best seen at Figures 1, 2, 18, and 19, the cutter head shafts e¹ e¹ are formed
at their lower extremities with pulleys el el, around which is passed a belt J for
rotating said cutter-heads, so that their adjacent faces move in the same direction,
as shown by arrows at Figures 18 and 19.
The belt J is driven in the directions also shown by arrows at Figures 18 and 19,
by front and rear driving pulleys K K fixed upon the shaft k, and is passed around
idlers K K fixed respectively upon the shafts The opposite ends of the
shaftskare journalled in the opposite walls AA of the left-hand extremity of
the frame A, and the shaft is journalled in a supporting bearing, which is
movable in guides A A in the inuer faces of the walls A³ A³, and is forced to the
desired position by a suitable adjuster, Figures 15 and 16 having one end bearing
against a downturned arm 15 upon the bearing ³, and the other movable in a
supporting bar A interposed between the frame walls A° A'.
The belt J is passed beneath the idler K', is twisted a quarter turn and extended
to the right-hand, so as to pass around the right-hand pulley ", is then twisted a
quarter turn and extended to the left-hand so as to pass beneath the rear driver K,
is then passed upwardly from the rear driver, twisted a quarter turn, and extended
to the right-hand so as to pass around the left-hand pulley e", is again twisted a
quarter turn and extended to the left-hand and passed over and beneath the idler K,
is then extended to the right-hand and passed over and beneath the front driver K,
and is finally extended to the left-hand and passed over the idler K. The
iller K, being mounted on a movable hearing, is readily adjusted to properly tension
the belt J, and this ten-ion is uniform irrespective of the amount of separation of
the cutter-heads E E, since, as one cutter-head moves away from the driving
pulleys and the idlers, the other cutter-head moves an equal distance towards said
driving pulleys and idlers.
As previously stated the shaft is revolved by the tight and loose pulleys (15 (1
in the direction shown by arrow 3 at Figure 1, and the belt J and idlers K Kare

page_text: then arranged as just described. It sometimes happens, however, that the power
transmitting mechanism for revolving the pulleys C18 C1 is arranged to revolve the
same in the opposite direction, and, instead of re-arranging said mechanism, the
idlers K¹ K² are preferably slid lengthwise of the shafts k¹² into alignment with
the rear driver K instead of the front driver.
The belt J, is then revolved in the direction shown by arrows at Figures 25 and 26,
and is then passed beneath the front driver K, is twisted a quarter turn, and
extended to the right-hand so as to pass around the right-hand pulley el, is then
twisted a quarter turn and extendel to the left-hand so as to pass beneath and over
the idler K', is then extended to the right-hand and passed beneath and over the
rear driver K, is then extended to the left-hand, and passed beneath and over the
idler K2, is then twisted a quarter turn and extended to the right-hand so as to pass
around the left-hand pulley e", and is then twisted a quarter turn extended to the
left-hand and passed beneath the front driver K.
The operation of this invention will be readily perceived from the foregoing
description and upon reference to the drawing, and it will be particularly noted that
the boards or shooks are readily adjusted in position upon their supports, are firmly
clamped in their adjusted position, and that their ends are quickly and practically
provided with grooves, which are exactly true, and facilitate the ready assemblage
of the box shooks, and that the parts of said invention are simple in construction,
economically manufactured, readily assembled, easily and practically operated, are
efficient in operation, and durable in use.
It is evident, however, that considerable change may be made in the relative
construction and arrangement of the parts of this grooving machine, hence
this invention is not limited to the described construction and arrangement of
