United States of America, now of 8 Southampton Buildings, London, for an
Invention of "IMPROVEMENTS IN MACHINERY FOR TRIMMING OR DRESSING
THE EDGES OF WOODEN PACKING CASES OR BOXES OR OF PIECES TO BE USED
IN THE MANUFACTURE OF THE SAME."
PROVISIONAL SPECIFICATION left by the said Frederick Myers at the
Office of the Commissioners of Patents on the 28th January 1882.
FREDERICK MYERS of the City and State of New York United States of
America now of 8 Southampton Buildings London, "IMPROVEMENTS IN MACHINERY
FOR TRIMMING OR DRESSING THE EDGES OF WOODEN PACKING CASES OR BOXES,
OR OF PIECES TO BE USED IN THE MANUFACTURE OF THE SAME."
This Invention relates to improvements in machinery for trimming or dressing
the edges of wooden packing cases or boxes or for dressing the edges of pieces
prior to their being nailed together in the manufacture of such cases or boxes
The first part of the said Invention consists in improved apparatus which may
be used as an attachment to the class of machines for trimming the edges of the
bottoms of packing cases or boxes after they have been nailed upon the sides, and
ends, described in the Specification of former Letters Patent dated September 1st
A.D. 1880 No 3548. The said apparatus has for its object to trim the top edges
of the sides of packing boxes or cases even with the top edges of the ends of the
same so that the cover or lid will fit evenly upon both the said sides and ends, this
trimming of the said top edges being effected at the same time as the trimming of
the edges of the bottoms of the said boxes or cases.
In the manufacture of packing cases or boxes of boards which have not been
very accurately dressed to size the top edges of the sides generally project
somewhat higher than the ends of the box or case and have to be dressed off level
or flush with the said ends preparatory to the application of the lid or cover which
should bear alike upon the edges and ends. By this part of my Invention I effect

page_text: the proper trimming of the said top edges and accomplish the same more cheaply
than is possible by hand, and at the same time that the edges of the bottoms of the
boxes are being trimmed as above stated.
In carrying this first part of my Invention into practice, I employ, ns in the
trimming machines of the class above referred to, a table or bench over which the
boxes or cases are caused to pass upon suitable ways by means of an endless feed
belt or chain having pushing rollers or pushers which carry the box or case along
so that the edges of its bottom are dressed or trimmed even with the sides of the
said box or case by means of rotating cutters one of which is adjustable laterally
to suit boxes of different widths. With a machine embodying these features I
combine my improved apparatus for trimming or dressing the top edges of the box
or case. This apparatus consists essentially of two rotating planers or cutters
arranged upon a horizontal shaft and a guiding or cutter-controlling shoe or piece
mounted above the table of the machine, and the feed belt in connection therewith.
The said cutters are mounted upon a rod or shaft supported in suitable arms
pivotted to, and free to turn upon, a rod or shaft fixed in standards or other suitable
supports attached to the table of the machine. The aforesaid shoe is provided
with an arm which is pivotted to an arm arranged upon another shaft or rod that
is also supported by the arms above described so that it may rise and fall with the
rotary planers or cutters and also be adjusted vertically independently of the said
cutters.
The said cutters and shoe when thus mounted or supported are preferably nearly
counterbalanced in a horizontal position, or nearly so, by means of a weighted lever
or counterpoise and below one of the arms carrying the cutter shaft is an adjustable
stop or support preferably consisting of a screw-rod against which the said arm
come to rest when the aforesaid shoe is not raised by the passage of a box or case
to be trimmed through the machine.
This adjustable stop-and-the-counterpoise are not however indispensable, as, with
the assistance of an attendant the machine will operate, properly without them. I
prefer, however, to use the said stop and counterpoise, as the machine will then
operate automatically after being once set or adjusted to suit any given size of box
or case to be trimined.
The aforesaid shoe is provided with a support whereon the planer or cutter shaft
dress or trim the
comes to rest so that the cutters will be properly gauged so as
This rest is
edges of the box-sides even with the underside of the said shoc.
movable lengthwise upon the shoe to compensate for slight variations of the cutter
shaft or arbor along the shoe caused by the upward and downward movement of
the same on the arm to which it is pivotted, which arm is shorter than the arms
that carry the cutter-shaft and is secured to its shaft by a clamping nut or other
suitable device.
One of the cutters or planers is fixed upon the cutter-shaft by means of a gib
and set screw so that it inay be readily loosened and slipped lengthwise of the
said shaft to suit boxes of different width or breadth, and the guide upon the table
of the machine and on the same side of the said machine, as this movable cutter is
also made adjustable for this purpose by means of brackets and clamp bolts or nuts.
The aforesaid cutters or planers are driven by a short belt from a loose double
pulley upon the shaft whereon the arms which support the cutter-shaft are fixed,
the said double pulley being driven by a belt passing around a pulley on the
driving shaft of the machine.
The shoe is located about midway between the planers or cutters so as to bear
upon the ends of the box and thus control the descent of the said planes or cutters
under which the sides of the box or case pass so as to dress their edges on a line
with the lower surface of the shoe and consequently level with the end edges of
the box or case upon which the lower surface of the said shoe rests.
Before commencing work upon the machine the aforesaid adjustable stop or
support is so set that the shoe will drop slightly below the level of the ends of
the box to be dressed before the same passes under it and the arm carrying the

page_text: said shoe is so set that when the latter comes to its proper level the bearing
thereon will come in contact with the cutter-shaft so that the latter is practically
supported through the said shoe on the box ends while the boxes pass under the
cutters, and thin edges are being dressed, the shoe being lifted slightly by the box
as soon as the forward end of the latter passes under the shaft carrying the said
cutters.
In some cases, instead of supporting the shoe upon an arm attached to a separato
rod as herein before described, I dispense with the said arm and shaft and support
the said shoe by means of a hanger or bearing which is fitted directly on the cutter-
shaft. In this case the weighted lever is connected by a cord or chain directly to
the said hanger instead of to the aforesaid arm or its shaft.
In the machines as heretofore constructed for dressing the bottom orges of the
box the table is provided with a way or support upon each side of the endless belt
for carrying the boxes forward, the upper surface of these ways being slightly
above the belt. The said ways support the box satisfactorily when the bottom
edges only of the same are to be trimmed in passing through the machine. If,
however, the top edges of the sides are to be trimmed at the same time as the
bottom edges these supports do not in all cases act satisfactorily as it frequently
happens that the bottoin of the box is made up of two or moro narrow pieces of
wood one of which is of less thickness than another. In such a case one side of the
box when passing over the said supports, would not be quite so high as the other
side, consequently one of the top edges of the box to be dressed would be too low
and the other edge too high to permit the proper action of the cutters or planers
thereon. I therefore form one of the said ways of a spring or springs which will
lift the thinner side of the botton and cause the box to present both of the upper
edges of its sides on a level to the cutters or planers and which will be depressed in
case a portion of the bottom of a box of greater thickness than that resting upon
the other way is passing over the said yielding way or support. When it is
desired to trim the bottom edges of boxes whose sides are formed of comparatively
thin wood, on machines of the class described in the Specification of the said
former Letters Patent it frequently happens that the loose collar, washer gauge, or
disc arranged upon the rotating cutter-shaft as therein described exerts such a
force upon the said sides as to bend them inwards and thus cause the cutter to cut
too deeply and in many cases to cut entirely through the side. To obviate this
difficulty when such boxes are being trimmed I arrange upon the cutter-shaft
instead of the said washer-gauge, a long bar or guide which, when a box or case is
passing through the machine, presses against the whole length of the side of tho
said box or case to be trimmed and thus prevents the bulging in of a portion of
the side, due to the excessive pressure thereon ordinarily produced by the said
washer-gauge and consequently ensures the proper trimming of the bottom edge
flush with the sides of the box. In order to support this bar or guide I attach to
the table of the machine, and adjacent to each end of the said bar or guide, a support
or bracket whercon the same rests and is free to move laterally to a slight extent.
The bracket at the end of the machine at which the box enters is provided with a
spring which bears against the adjacent end of the guide or bar and constantly
tends to force the same inward into contact with the box. The second part of this
Invention relates to an improved machine for trimming or dressing the ends of
pieces of wood prior to their being nailed together to form packing cases or boxes.
For this purpose I secure to the table of the machine two guide pieces that fit over
extensions or lugs upon a base or bed-plate which supports, by means of two bars,
or guide-ways, plates whereon the pieces of wood to be trimmed are placed. One
of these bars is formed in one piece with the said bed-plate and the other is made
adjustable thereon so that the plates for carrying the wood may be clamped firmly
in position between the said bars or be left free to be moved longitudinally between
the same as hereinafter described. In order to adjust the said movable bar upon
the bed-plate I prefer to employ screw rods which extend through the har, formed
in one piece with the said bed-plate, through screw-threaded or tapped holes in the

page_text: adjustable bar, and into lugs on the said bed-plate, the said screw-rods being
prevented from endwise movement in the first named bar and in the lugs, in any
suitable manner. It follows therefore that by turning the said screw rods or
screws by means of a handle, or in any other suitable manner, the adjustable bar
may be drawn towards the wood-supporting plates so as to clamp them between
the two bars, or the said adjustable bar may be adjusted away from the said plates
so that they may be freely moved between the said bars longitudinally. To prevent
the displacement of the movable bar during its adjustment, I prefer to provide the
same with lugs or ears having slots into which pins on the bed-plate project.
The plates for supporting the wood are preferably provided with ribs whereon
the pieces of wood rest, and with vertical projections or stops on one side, against
which stops the side edges of the pieces of wood are placed.
The aforesaid plates, and the bed-plate carrying the same, are adapted to be
moved longitudinally by means of a crank-handle or lever, preferably arranged at
one side of the machine and attached to a transverse shaft which is supported in
suitable bearings below the table of the said machine, and is connected by a lever
or crank-arm to a projection or bracket on the underside of the said bed plate.
To provide for holding the series of pieces of wood to be trimmed firmly, upon their
supporting plates, I attach, preferably to the aforesaid adjustable bar an arm
or bracket to which is hinged or pivotted an arm or bridge piece which extends
over the wood supporting plates and is preferably connected to the bar formed on
the bed plate by a hook, hasp, or other suitable fastening. In this arm or bridge-
piece I provide a screw connected with a platen or follower, preferably of wood,
which, by turning the said screw, may be brought firmly into contact with the
wood so as to clamp, and prevent the displacement of, the same whilst being
trimmed.
Upon the aforesaid table and adjacent to the two ends of the wood-carrying
plates I arrange-two-carriages which may be adjusted longitudinally upon the said
table by means of a screw supported in suitable bearings attached to the latter, or
to the main frame of the machine and passing through lugs upon the underside of
the said carriages. One end of the said screws is provided with a right handed
screw thread and the other with a left handed screw thread so that by turning the
same the two carriages may be caused to simultaneously approach or recede from
each other. Upon each of these carriages I provide suitable ways wherein a slide
carrying the planing or cutting tool is free to travel transversely. This slide is
attached to one end of a connecting rod whose other end is secured in a radial slot
in a crank disc fixed upon a shaft supported in bearings upon the carriage.
This shaft carries a pulley which is driven by a bolt passing over a pulley on
the main driving shaft, the last named pulley being of such a length as to permit
the longitudinal adjustment of the carriage without causing the disconnection of
the belt from the said pulley.
The tool-carrier is hinged or pivotted to the transversely reciprocating slide so
that the said tool may be properly adjusted with regard to the work to be
trimmed. The said carrier is held in the desired position when the tool is properly
set or adjusted, by means of a screw passing through a slotted car or lug on the
said carrier into a tapped hole in the slide.
To vary the throw or reciprocating movement, of the slide and tool the aforesaid
radial slot is formed in the crank-disc so that by moving the bolt which secures
the connecting rod to the latter, to or from, the centre of the said disc, the throw of
the tool will be decreased or increased.
In practice, the boards or pieces of wood to be trimmed are placed upon the
supporting plates which are separated from each other to such a distance that the
portion to be cut off from the ends of the same project beyond the ends of the
said plates. These plates are then clamped between the adjustable and non-
adjustable bars, and the screw platen or follower is caused to clamp the pieces of
wood firmly in position. The handle or lever on the end of the transverse shaft
is then turned in one direction so as to move the bed-plate and the wood carried by

page_text: the plates thereon. towards one of the reciprocating cutters, and such wood is pressed
by the said handle into contact with the said cutter until the edge of the piece of
wood is properly trimmed. The handle. on the transverse shaft is then moved in
the opposite direction and the other edge of the wood brought into contact with
the other reciprocating cutter so that that edge is trimmed. The wood is then
removed and is ready to be made up into boxes.
To regulate the amount of wood cut off from the ends of the pieces supported
upon the plates, I prefer to provide the same with studs or projections, which, when
the requisite amount of wood is removed, come in contact with stops on the
carriage whereon the cutter slides, and thus prevent any further movement of the
wood towards the said cutter by the exertion of pressure upon the handle of the
transverse shaft.

by the said Frederick Myers in the Great Seal Patent Office on the 28th
July 1882.
FREDERICK MYERS of the City and State of New York, United States of
America, now of 8, Southampton Buildings, London. " IMPROVEMENTS IN
MACHINERY FOR TRIMMING OR DRESSING THE EDGES OF WOODEN PACKING CASES
OR BOXES, OR OF PIECES TO BE USED IN THE MANUFACTURE OF THE SAME."
This Invention relates to improvements in machinery for trimming, or dressing
the edges of wooden packing cases or boxes or for dressing the edges of pieces of
wood prior to their being nailed together in the manufacture of such cases or
boxes..
The first part of the said Invention consists in improved apparatus which may
be used as an attachment to the class of machines, for trimming the edges of the
bottoms of packing cases or boxes after they have been nailed upon the sides and
ends, described in the Specification of former Letters Patent dated First September
A.D. 1880. No. 3548.
The said apparatus has for its object to trim the top edges of the sides of packing
boxes or cases even with the top edges of the ends of the same, so that the cover
or lid will fit evenly upon both the said sides and ends, this trimming of the top
edges being effected at the same time as the trimming of the edges of the bottoms
of the said boxes or cases.
;
In the manufacture of packing cases or boxes, of boards which have not been
very accurately dressed to size, the top edges of the sides generally project somewhat
higher than the ends of the box or case, and have to be dressed off level or flush
with the ends preparatory to the application of the lid or cover which should bear
alike upon the edges and ends. By this part of my Invention I effect the proper
trimming of the top edges of the sides and accomplish the same more cheaply than

page_text: is possible by hand and at the same time that the edges of the bottoms of the
boxes are being trimmed, as above stated.
This part of iny Invention is illustrated in Figures 1 to 5 of the accompanying
Drawings in which
Figure 1 is a plan or top view of a machine such as is now used for trimming
the edges of the bottom of a box or case level with the sides thereof, with my
improved attachment for trimming the top edges of the sides flush with the ends,
applied thereto.
Figure 2 is a side elevation and
Figure 3 an end elevation of the said machine and attachment.
Figure 4 is a plan of the said attachment detached from the machine and drawn
to an enlarged scale
Figure 5 represents a modified construction of the shoe hereinafter described
The remaining Figures will be hereinafter referred to.
In carrying the first part of my said Invention into practice I employ, as in the
trimming machines of the class above referred to, a table or bench A over which
boxes or cases, such as that shewn at B, are caused to pass upon suitable ways by
means of an endless feed belt or chain C having pushing rollers or pushers D which
carry the box or case along so that the edges of its bottom are dressed or trimmed even
with the sides of the said box or case, by means of rotating cutters E, one of which is
adjustable laterally to suit boxes of different widths. With a machine embodying
these features I combine my improved apparatus for trimming or dressing the top
edges of the sides of the box or case. This apparatus consists essentially of the
rotating planers or cutters F mounted upon the rod or shaft G and a guiding or
cutter-controlling shoe or piece H, all mounted above the table A of the machine,
and the feed-belt C in connection therewith. The said shaft G is supported in
suitable armis I, I pivotted to, and free to turn upon, a rod or shaft J fixed in
-standards K.K.or other suitable supports attached to the table of the machine.
The aforesaid shoe H is provided with an arm or extension-H-which is pivotted
to an arm L arranged upon the shaft or rod M that is supported by the arms I I,
abovo described, so that the said shoe may rise and fall with the rotary planers or
cutters F and may also be adjusted vertically independently of the said cutters.
The cutters F and shoe H, when thus mounted or supported, are preferably nearly
counterbalanced in a horizontal position or an approximately horizontal position,
by means of a weighted lever or counterpoise N, and below one of the arin I
carrying the cutter-shaft G is an adjustable stop or support O, preferably consisting
of a screw-rod against which the said arm comes to rest when the aforesaid shoe is
not raised by the passage through the machine of a box or case to be trimmed.
This adjustable stop O and the counterpoise are not however indispensable, as
with the assistance of an attendant the machine will operate properly without
them. I prefer, however, to use the said stop and counterpoise as the machine will
then operate automatically after being once set or adjusted to suit any given size
of box or case to be trimmed.
The shoe H is provided with a support P whereon the cutter-shaft G rests so
that the cutters will be properly gauged in such a manner as to dress or trim the
edges of the box-sides even with the underside of the said shoe. This rest is
movable lengthwise upon the shoe to compensate for slight variations of the cutter-
shaft along the shoe, caused by the upward and downward movement of the same
on the arm L to which it is pivotted, which arm is shorter than the arms I, that
carry the cutter-shaft, and is secured to its shaft by a clamping nut L', or other
suitable device.
One of the cutter-heads or carriers is fixed upon the cutter-shaft by means of a
jib Qand set-screw Q', so that it may be readily loosened and slipped lengthwise of
the said shaft to suit boxes of different widths; the guide R, upon the table A, and
on the same side of the machine as this movable cutter-head is also made adjustable
for this purpose by means of brackets or slotted extensions R' and clamp-bolts or
nuts R.

page_text: The aforesaid cutters are driven by a belt S¹ from a double pulley T loose upon
the shaft J, the said double pulley being driven by a belt Ū passing around a
pulley V on the driving shaft of the machine.
The shoe H is located about midway between the cutters so as to bear upon
the ends of the box and thus control tlie descent of the cutters under which the
sides of the box or case pass, so as to dress the edges of the said sides on a line
with the lower surface of the shoe and consequently level with the end edges of
the box or case upon which the lower surface of the said shoe rests.
Before commencing work upon the machine, the adjustable stop or support O is
so set that the shoe H will drop slightly below the level of the ends of the box to
be dressed before the same passes under it, and the arin L carrying the said shoe is
so set that when the latter comes to its proper level the bearing P, thereon will
come in contact with the cutter-shaft G so that the latter is practically supported
through the said shoe on the box ends while the boxes aro passing under the
cutters and their edges are being dressed, the shoe being lifted slightly by the box
as soon as the forward end of the latter passes under the cutter-shaft.
In some cases, instead of supporting the shoe upon the arm L attached to a
separate rod, as hereinbefore described, I dispense with the said arm and shaft and
support the said shoe by means of a hanger or bearing H*, seo Figure 5, which is
fitted directly on the cutter-shaft G. In this case the weighted lover is connected
by a cord or chain directly to the said hanger, instead of to the aforesaid arm or
its shaft.
In the machines as heretofore constructed for dressing the bottom edges of the
box, the table A is provided with a way or support W upon each side of the
endless belt C for carrying the boxes forward, the upper surface of these ways
being slightly above the belt. The said ways support the box satisfactorily when
the bottom edges only of the same are to be trimmed in passing through the
machine. If however the top edges of the sides are to be trimmed at the same
time as the bottom edges, these supports do not in all cases act satisfactorily, as it
frequently happens that the bottom of the box is made up of two or more narrow
picces of wood, one of which is of less thickness than another.
In such a case one side of the box, when passing over the said supports, would
not be quite so high as the other side, consequently one of the top edges of tho
box to be dressed would be too low and the other edge too high to permit the
proper action of the cutters F thereon. I therefore provide one of the said ways
with a spring or springs X which will lift the thinner part of the bottom of the
box and cause the said box to present both of the upper edges of its sides on a
level to the cutters F, and which will be depressed in case a portion of the bottom
of a box of greater thickness than that resting upon the other way is passing over
the said yielding way or support.
When it is desired to trim the bottom edges of boxes whose sides are formed of
comparatively thin wood on the trimming or dressing machines of the class
described in the Specification of the said former Letters Patent, it frequently
happens that the loose collar, washer, gauge, or disc arranged upon the rotating
cutter-shaft as therein described, exerts such a force upon the said sides as to bend
them inwards and thus cause the cutter to cut too deeply, and in many cases to
cut entirely through the side. To obviate this difficulty when such boxes are
being trimmed, I employ the devices illustrated in Figures 6, 7 and 8 of the
Drawings in which
Figure 6 is a plan or top view of the said devices and
Figures 7 and 8 are transverse sections of the same on the lines x, x and y, y,
Figure 6.
8 represents the cutter-shaft upon which I arrange, in place of the said loose
collar or gauge, a long bar or guide t, which, when a box or case is passing through
the machine, presses against the whole length of the side of the said box, or case
and thus prevents the bulging in of a portion of the side due to the excessive
pressure thereon ordinarily produced by the use of the said loose collar or gauge

page_text: and consequently ensures the proper trimming of the bottom edge flush with the
sides of the box. In order to support this bar or guide I attach to the table of the
machine, and adjacent to the ends of the said bar or guide, the supports or brackets
u, u' whereon the same rests and is free to move laterally to a slight extent. The
bracket u, at the end of the machine at which the box enters, is provided with a
spring which bears against the adjacent end of the guide or bar t and constantly
tends to force the same inward into contact with the box, but this spring may, if
desired, be dispensed with.
The second part of this Invention relates to an improved machine for trimming
or dressing the ends of pieces of wood prior to their being nailed together to form
packing cases or boxes
This part of my said Invention is illustrated in Figures 9 to 11 in which
Figure 9 is a plan or top view of the said machine with the wood clamping
devices hereinafter described removed,
Figure 10 is a front elevation of the same and
Figure 11 is a transverse section of the upper portion of the machine with the
said clamping devices in position.
In these Figures a represents the table of the machine supported upon suitable
legs or standards, portions of which are shewn in Figure 10 at b. To this table I
secure two guide-pieces c that fit over extensions or lugs d' upon a base or bed-
plate & which supports by means of two bars or guide-ways e, e¹ plates ƒ, ƒ
whereon the pieces of wood to be trimmed aro placed, as shewn in Figures 10
and 11. The bar e is formed in one piece with the bed-plated and the other bar c¹
is adjustable thereon so that the plates f,f for carrying the wood may be clamped
firmly in position between the said bars or be left free to be moved longitudinally
between the same as hereinafter described. In order to adjust the movable bar e'
upon the bed-plate d I prefer to employ screw-rods g which extend through the
--bare through. screw-threaded holes in the adjustable bar c' and into lugs d* on
the bed-plated, tho said screw rods being prevented from end wise movement in
the bar e and in the lugs d* in any suitable manner. It follows therefore that by
turning the said screw-rods or screws g by means of a handle or lever g' or other
suitable means, the adjustable bar e¹ may be drawn towards the wood supporting
plates so as to clamp them between the two bars, as shewn in Figure 11, or the
said bar e' may be adjusted away from the plates so that they may be freely
moved between the said bars longitudinally. To prevent the displacement of the
movable bar during its adjustment I prefer to provide the same with lugs e² having
slots into which pins on the bed-plate project.
The plates are preferably provided with ribs ff whereon the pieces of
wood rest and with vertical projections or stops f* on one side, against which stops
the side edges of the pieces of wood are placed as shewn in Figure 11.
The plates fand the bed-plate d carrying the same are adapted to be moved
longitudinally by means of a crank-handle or lever h¹ preferably arranged at one
side of the machine and attached to a transverse shaft which is supported in
suitable bearings below the table a and is connected by a lever or crank-arm h² to
a projection or bracket d on the underside of the bed-plate d.
To provide for holding the series of pieces of wood to be trimmed firmly upon
their supporting plates I attach, preferably to the bar e¹, an arm or bracket i to
which is hinged or pivotted an arm or bridge-pieco ; which extends over the
plates and is preferably connected to the bar e by a hook or other suitable
fastening at j. In this arm or bridge-piece I provide a screw connected with a
platen or follower k¹ preferably of wood, which, by turning the said screw, may be
brought firmly into contact with the wood as shewn in Figure 11, so as to clamp
and prevent the displacement of the same whilst being trimmed.
Upon the table a and adjacent to the two ends of the plates f, I arrange two
.carriages l, which may be adjusted longitudinally upon the said table by means
of a screw m supported in suitable bearings attached to the table or to the main
frame of the machine and passing through lugs at * upon the underside of the said

page_text: carriages. One end of the said screw is provided with a right handed screw-throad
and the other with a left handed screw-thread, as shewn, so that, by turning the
said screw the two carriages 1, l' may be caused to simultaneously approach, or
recede, from each other. Upon each of these carriages, I provide ways whereon a
slide a carrying the cutter n¹ is free to travel transversely. This slide is attached
to one end of a connecting rod o whose other end is secured in a radial slot in 'a
crank disc p² fixed upon a shaft p supported in bearings upon the carriage. This
shaft carries a pulley p' which is driven by a belt passing over a pulley q¹ on the
main driving shaft the pulley q' being of such a longth as to permit the
longitudinal adjustment of the carriage without causing the disconnection of
the belt from the said pulley.
The cutter carrier n² is hinged or pivotted to the transversely reciprocating slide
at n so that the cutter may be properly adjusted with regard to the work to be
trimmed. The said carrier is held in the desired position, when the cutter is
properly set or adjusted, by means of a screw n* passing through a slotted lug on
the said carrier into a trapped hole in the slide.
To vary the throw or reciprocating movement of the slide and cutter the
aforesaid radial slot is formed in the crank-disc pl so that by moving the bolt
which secures the connecting rod to the latter to or from the centre of the said disc,
the throw or travel of the cutter will be decreased or increased.
In practice, the boards or pieces of wood to be trimmed are placed upon the
supporting plates ff which are separated from each other to such a distance that
the portions to be cut off from the ends of the same project beyond the ends of the
said plates as shewn in Figures 10 and 11. These plates are then clamped
between the bars e, el and the screw platen or follower is caused to clamp the
pieces of wood firmly in position. The handle or lever h¹ on the end of the trans-
verse shaft is then turned in one direction so as to move the bed plate d and the
wood carried by the plates f thereon towards one of the reciprocating cutters n'
and such wood is pressed by the handle into contact with the cutter until the end
edges of the pieces of wood are properly trimmed. The handle or lever is then
moved in the opposite direction and the other end-edges of the wood are brought
into contact with the other reciprocating cutter n and trimmed thereby. The wood
is then removed and is ready to be made up into boxes.
To regulate the amount of wood cut off from the ends of the pieces supported
upon the plates f, f', I prefer to provide the same with studs or projections ƒ³,
which, when the requisite amount of wood is removed, come in contact with stops ?
and thus prevent any further movement of the wood towards the said cutter by
the exertion of pressure upon the handle h'.
Having thus fully described my said Invention, and the manner of performing
the saine, I wish it understood that I claim
First. The combination, with a machine for trimming the edges of the bottoms
of packing cases or boxes, of the attachment or devices for simultaneously dressing
the top edges of the sides of the same, constructed and operating substantially
as set forth.
Second. The combination with the table A, the feed belt C, and the rotating
cutters E, of the shoc H, and the cutters F adapted to dress the top edges of the
sides of a box even with the ends thereof, and with or without the weighted
lever or counterpoise, all substantially as above set forth, and for the purposes
specified.
Third. The combination, with the shaft carrying the cutters F and supported in
the arms I, of the shoe H provided with the support P and connected with the
rod M by the arm L, and the adjustable support O, all substantially as above set
