COMPLETE SPECIFICATION.
Improvements in Box Machines.
We, HARRY WARD MORGAN, of Rochester, in the County of Monroe, State of
New York and CHARLES MOGRIDGE LORING, of Minneapolis, in the County of
Hennepin, State of Minnesota, United States of America, Gentleman, do hereby
leclare the nature of my invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
tatement:
My present invention relates to machines for readily assembling or putting
together that class of boxes in which the sides and ends are secured together by
nterlocking tongues and grooves, though readily adapted for entering and firmly
securing tongued boards or strips, and it has for its object to provide a machine
that is simple in its construction and which will cause the interlocking tongues on
the boards or strips to be entered accurately and positively secured, the machine
being capable of adjustment so as to prevent improper operation and to suit
varying thicknesses of material, and to these and other ends it consists in certain
improvements in construction and combinations of parts, all as will be hereinafter
fully described and the novel features pointed out in the claims at the end of this
Specification.

The main frame of the machine consists of a bed or casting 1 having supporting
legs 2 and in its top are provided ways extending at right angles to each other and
crossing at the center of the machine in which operate suitable slides or abutments
adapted to carry the side and end pieces of the box to be put together. These
slides are arranged in pairs set opposite and one of each pair is supported on a
carriage which is movable toward and from the other (stationary) one during the
operation of setting up the box and the two co-operating slides are adjustable and
preferably simultaneously toward and from each other so that though the amount of
the movement of the carriage is practically constant the distance between the two

page_text: slides may be varied to operate on different sizes of boxes. As the construction of
the two stationary slides is identical excepting in a single instance, which will be
described, and also as the movable slides are the same in construction a specific
descriptin of one of each will enable the machine to be readily understood.
Referring particularly to Figure 1, the slides 3 and 4, shown at the bottom and
left of said figure, are the ones termed "stationary," located directly opposite their
corresponding movable slides 3 and 4 and are supported upon flanges 2 in the
frame 1, being held in position by plates 5, or other suitable means. On the main
frame and at the ends of the ways for the stationary slides are arranged vertical
extensions 7 through which pass adjusting screws 6, 6*, entering the slides and
prevented from longitudinal movement by collars 7* and sprocket wheels 8, 8×,
arranged on opposite sides of the extension. In the tops of the stationary slides
are undercut grooves 8 adapted to receive the heads of bolts 9 passing up through
brackets 10, two of which are arranged upon each slide, nuts 11 on the ends of the
bolts serving to clamp the brackets securely to the slide when adjusted. The
forward projecting portions of the brackets 10 are provided with vertical bearings
in which are located rods or pins 30x and on these rods are journalled the board
carriers 12, the latter being provided with two perforated lugs and with pins 13
adapted to engage the brackets 10 and limit the rotary motion of the carriers
caused by the springs 14 encircling the rods and engaging at opposite ends the
carriers and brackets. The outer faces of the carriers 12, which are preferably
narrow, are curved preferably on an arc struck from the center of the pin 30*, the
upper end being beveled slightly as shown in Figure 8 and in one side it is provided
with a longitudinal groove 15 in which operates a headed pin 16 carrying the
plate 17 projecting forward of the carrier and serving as a support for the board,
said plate being provided on the surface in contact with the side of the carrier with
a series of notches or teeth adapted to co-operate with corresponding teeth 18 formed
on the carrier and to be secured rigidly in position by means of a small nut 19
operating on the screw 16, as shown more particularly in Figure 13.
The movement of the surface of the carriers laterally is in a direction to cause
the tongues of the board to engage readily with those of the co-operating board at
the end without undue friction on the slide carrying it.
The faces of the carriers are rounded concentric with their center of motion, so
that when turned on their pivots, the plane of the face of the board will not be
changed, and they are permitted an oscillatory movement rather than a rotary
movement on their center of rotation, so that the same surface acts on the board
at every operation and they are thereby kept free from glue, as further on
explained.
Arranged in suitable recesses in the lower side of the slides 3 and 4 are board
holders or pressers consisting of slides 20 arranged to hold the boards on the
carriers and prevent inward movement of the central portions during the operation,
having vertical portions 75 at their forward ends upon the inner side of which are
journalled small rollers 21; said vertical extensions being located about mid-way
between the board carriers, two of which are provided upon each slide. These
pressers are normally held retracted by means of springs 22 fastened to the rear of
the stationary slides and their inward movement is arrested by the washers or
collars 23 on the end of horizontal rods 24 normally pressed forward or toward the
center of the machine by springs 25, stronger than springs 22, encircling the rods
and arranged between the pins 26 thereon and the rear of the main slide. The
undersides of the pressers 20 are provided with longitudinal slots 27 and apertures
through which pass rods 28 extending toward the center of the machine and
having secured to them threaded pins 29 engaged by nuts 30 having extended
handles 31; said nuts being broader than the slots 27 and serving not only as a
means for securing the rods 28 to the slides, but also, when loosened, as a means for
operating said rods longitudinally through the medium of the extended handles 31,
all as shown more particularly in Figures 4 and 5.
The description thus far applies equally well to the two slides 3 and 4 excepting

page_text: as to the direction in which the carriers 12 are capable of swinging movement,
which movement as will be noted is governed by the stop pin 13.
Located in the guide ways in the main frame of the machine and opposite the
stationary slides 3 and 4 are the co-operating slides 3 and 4*, the former being
directly.opposite the slide 3 and the latter opposite the slide 4 and excepting as to
the means for operating the carriages on which said slides are secured and as to
length (the slides 4 and 4* being used for the sides of oblong boxes are longer)
their construction is identical so that a description of one will suffice for both.
These slides are mounted upon carriages 36 and 37 sliding on guide ways 40* in
the main frame and are adjustable thereon by means of screws 41, 41*, journalled
in vertical extensions 42 of the carriage and prevented from longitudinal movement
therein, said screws entering threaded perforations in the main carriages, so that
by the adjustment the slides will be moved back and forth on the carriage as will
be understood. The guides or supports 40* for the carriages are arranged in a
lower plane than those for the slides 3 and 4 in order that the board carriers and
pressers of each co-operating pair may be in substantially the same plane.
Secured to the upper sides of the slides 3* and 4* are brackets 10 carrying
board carriers 12, the same as those on the stationary slides and arranged in their
lower sides are pressers 43 corresponding to the pressers 20 in the stationary
slides 3 and 4, but instead of providing the underside of the pressers 43 with
slotted extensions they have depending lugs 44, as shown more particularly in
Figures 6 and 7. They are retracted however, by springs 22 and held against the
washers or collars 23, as are the others, and in their vertical extensions 45 are
journalled rollers 21* projecting toward the carriers 12 mounted on the slide.
Upon the screws 41 and 41* of each carriage are arranged sprocket wheels 46, 46*,
keyed or otherwise rigidly secured thereto and extending around said sprocket
wheels are chains 47, 47x, and also passing around corresponding sprockets 48, 48*,
arranged on shafts 49, 49*, journaled in suitable boxes 50 arranged in the lower
portion of the machine and adapted to be secured rigidly thereto by screws 51 or
other suitable devices to permit the vertical adjustment of the shafts for the purpose
of tightening the chains when desired. Upon the other ends of these shafts are
corresponding sprocket wheels 53, 54, connected by chains 53*, 54*, with the
sprockets 8, 8*, on the screws 6, 6*, of the corresponding stationary slides. The
outer ends of the screws 6, 6x are squared so as to adapt them to receive a
removable handle 52, as shown in dotted lines Figure 2, and as said screws 6, 6*,
and 41, 41, of co-operating slides are provided with left and right hand threads,
respectively, it will be seen that by operating one of them, motion will be com-
municated to the other through the chains and sprockets described and the
co-operating slides will be adjusted toward or from each other depending of course
upon the direction of movement.
Beneath the stationary slides 3 and 4 and projecting toward and extending past
the center of the machine are gage-rods 60, the forward ends being adapted, when
the movable slides are in their inmost position, to strike the lugs 44 on the lower
side of the pressers 43 carried by the movable slides 3* and 4*; said rods being
secured in position by set screws 61, as shown in Figure 11.
Supported in suitable bearings in the main frame of the machine are two
shafts 62 and 63 extending at right angles to each other and provided on their ends
with intermeshing beveled gears 64, the shaft 63 having a crank pin 65 on its end
connected by a link and pitman 66 with the carriage 36.
The end of shaft 62 is,
however, provided with a crank pin 67 entering a block 68 sliding in a slotted link
or pitman 69 pivotted to the carriage 37 and in the end of said link is a suitable
adjusting screw 70 secured by a set nut 71, the object of this adjustable connection
being to vary the time of the movement of this carriage 37 with relation to the
movement of the other one, when desired, so as to ensure the proper entering of
the tongues and grooves of the sides and ends of the box as will be further on
explained.
Secured to one of the brackets 10 on the slide 3 is a board gage or stop 99 with

page_text: which the end of the board on slide 4* co-operates when the slides are in outward
position but when the slides are moved inward, the board is released from the stop
and is free to move lengthwise the proper distance to form the fastening as shown
in Figures 1 and 14.
When the machine is not in operation, the crank pins 65 and 67 are in outmost
position holding the carriages outward and the shafts 62 and 63 may be rotated by
any suitable means, as for instance, a train of gears 72, 72' operated from a belt
pulley 73, as in Figure 1, or any other desired. It is desirable to employ
a clutch device of any preferred construction by the use of which the shafts
may be given a half rotation, so as to stop with the carriages moved inward. In
Figures 17, 18 and 19 I have shown a form of clutch which can be used with
success in this machine,-63 indicating the shaft on which the crank pin 65 is
secured, and 200 a sleeve splined to the shaft and on or over which the gear 72¹, or
a sleeve extension, runs loosely. This sleeve has a semi-circular groove in one
side in which is located a half round pin or key 201, having an arm 202 at one end
projecting parallel with the face of the gear, and the inside of the gear 72¹ is
provided with a series of recesses 203 adapted to be engaged by the pin 201 when
the latter is turned to the position in dotted lines Figures 17 and 18. The outer
face of the pin 201 is concentric with the inside of the gear 72' and when in the
position in full lines Figures 17 and 18 does not connect the sleeve and gear, but
permits the latter to rotate. freely. The sleeve 200 has an extension with a recess
in which the arm 202 is located and a spring 204 bearing on the arm tends to turn
the arm and pin so as to engage the sleeve and gear, if not retained. 205 indicates
an arm pivoted on the main frame connected with the treadle 98 and normally held
in line with the arm 202, holding the key out of engagement and the sleeve
disconnected from the gear. When, however, the machine is to be operated, the
arm 205 is removed, the spring turns the key so as to engage with one of the
recesses 203 in the gear and rotate the shaft 63 a whole rotation until the arm 202
again engages the arm 205, when the machine is arrested with the slides in outward
position. When it is desired to cause only a half rotation of the shafts, bringing
the slides inward for the purpose of adjustment, a pivoted hook-shaped arm 207
is moved from the normal position in full lines Figure 17 to the position in dotted
lines, where it will engage the arm 202 of the key and disengage the latter from
the gear in the same manner that arm 205 does, and by moving the arm 207 back
again the rotation of the shaft may be completed and the slides moved again to
outward position.
This is only one form of clutch device and other equivalent devices may be used
if desired.
The class of boxes to be set up or formed by this machine are composed of side
and end pieces having tongued and grooved ends adapted to be forced tightly
together to interlock and as usual to have glue applied to the ends for forming
good joints and secure fastenings and as the pieces are of a standard length the
machine being set for one size of boxes it will not require further change or
adjustment until another size is to be made.
In order to set the machine for operation the shafts 62 and 63 are given a half
revolution moving the carriages and movable slides inward, then all the brackets 10
are adjusted on their slides so that they will be near the corners of the box, but
will not touch each other when the box is being clamped, a standard box of the
size to be formed is placed between the slides, the rollers on the pressers 20 and 43
being engaged with the inner faces of the side and end pieces and held by their
springs 22 and the board supports 17 are adjusted to the proper height on the
carriers 12, which is facilitated by the serrations 18 on the sides of the latter
enabling the operator to readily locate all of them at the same height. The crank
handle 52 is applied to the end of the screws 6, 6x, and rotated in a proper
direction to cause the co-operating slides to approach each other until their
carriers 12 are forced against the sides of the box tightly, the simultaneous
movement of co-operating slides being caused by the sprockets and chains before

page_text: described. Then the gage rods 60 in the main frame are moved toward the center
of the machine until they abut against the lugs 44 on the pressers of the movable
slides, when they are firmly secured by their set screws 61; the nuts 30 are
loosened and the adjustable gage rods 28 in the pressers 20 are moved inward until
their inner ends engage the ends of the movable carriages 36 and 37, and said nuts
are again tightened. The machine having been thus adjusted for a box of certain
size the shafts 62 and 63 are rotated another half revolution and stopped, the
carriages and their slides being then in outward position, as in Figures 1 and 2, and
ready for making boxes. In this instance the machine is set for oblong boxes, but
it is evident that for making square boxes it is only necessary that the carriers on
the slides 3 and 3* be set further apart and the said slides adjusted the same
distance apart as are the slides 4 and 4*.
The operator now places the end boards of the box to be formed on the
support 17 on the carriers 12 of slides 3 and 3* and places the side boards on the
supports of the slides 4 and 4*, the board on the latter engaging the gage 99 on
slide 3, the beveled ends of the carriers facilitating their ready introduction
between them and the rollers 21 and 21* on the pressers 20 and 43. The shafts 62
and 63 are now rotated and the carriages carrying the movable slides are moved
toward the stationary slides, but their movement is so timed by the adjustment
of the set screw 70 in the pitman 69 that the slide 4* will have moved its board
away from gage 99 and far enough to engage the tongues on all the boards, the
ends of the end boards (on slides 3 and 3*) being inside the tongues on the
boards on slides 4 and 4*, so that the pressure will be first applied from slide 4*,
and the tongues on the end boards entered longitudinally preventing displacement,
as shown in Figure 14, and afterward the slides move together completing the
clamping.
It will be noted that the parts of the box are movable toward the corner between
the two stationary slides and that therefore the supports carrying the boards should
move in this direction, which is provided for in my machine by pivoting the
carriers 12 as shown, so that while they exert the necessary pressure on the boards,
they allow them to move as shown in dotted lines in Figures 1, 10 and 15, the
rollers 21 and 21* also permitting the necessary longitudinal movement of the
boards without undue friction.
These swinging oscillatory carriers I find particularly desirable for the further
reason that as the tongues on the boards are usually dipped in glue, which often-
times coines off on them, the rolling motion the carriers have on the boards squeezes
the surplus glue out from between the surfaces and leaves them practically free and
clean, so that there is no liability of the boards becoming marred by dried glue on
the carriers or of the displacement or disarrangement of those subsequently applied
to the carriers.
As the pressure forcing the tongues on the boards, is applied near their ends they
have a tendency to bow or bulge inward at the center making the sides or ends of
the box curved and as the fastening is a tight one they are liable to remain in this
condition and it is for the purpose of avoiding this and ensuring boxes of proper
shape that the gage rods 28 and 60 are employed for preventing the inward move-
ment of the pressers 20 and 43. When the carriages 36 and 37 reach the limit of
their inward movement the stationary gage rods 60 engage the lugs 44 on the
pressers 43 and arrest the latter holding the inner side of the board stationary and
preventing its bulging, and at the same time the carriages 36 and 37 engage the
gage rods 28 on pressers 20 and prevent movement of the latter ensuring the
formation of a box with rectangular sides. When, however, very thin boards are
employed, simply arresting the inward movement of the pressers by the gage rods
at the completion of the pressure will not suffice, as the boards will bend between
the holders and the carriers and to obviate this and ensure the proper operation
the gage rods 28 and 60 are set a little farther inward than for thick boards, so
that the holders will not only be arrested and prevented from moving away from
the collars 23 that normally arrest them, but they and the collars will be moved

page_text: backward (relatively) against the tension of the springs 25, the adjustment being
such that though the boards may bend as indicated in Figure 16, the ends of the
boards will be engaged properly and a rectangular box be formed. When the
sides and ends of the box are put together and secured as described the carriages
move outward again and the box can be removed and the lid and top nailed on in
the usual manner. When the carriages move outward the one 37 moves last owing
to the lost motion between the block in the pitman and the adjustable screw 70 on
the latter. When boxes employing sliding tops or covers are to be made, as the
sides or ends over which the cover moves must be shorter than the ones in which it
slides, the adjustable supports 17 supporting the narrower, boards may be readily
moved up on their carriers 12, the proper distance and secured, thereby ensuring
the proper relation of the parts.
The boards can be placed on the slides very rapidly by the operator when
using the machine, it only being necessary to have the board ou slide 4* against
the gage or stop 99 and to see that the other boards do not lap over the carriers
too far.
Notwithstanding the fact that the sprocket wheels on the screws of the
carriages are movable and those on the shafts 49, 49*, stationary, the chains
have sufficient flexibility to ensure the proper operation of the parts without
displacement.
While I have termed the parts 12 board carriers, I wish to be understood as
meaning the devices that carry or move the boards together and it is not absolutely
essential that they support the boards entirely also, as other supports than the ones
shown herein as mounted on the carriers could be employed.
The particular features which render this machine valuable and capable of
performing the operations properly are those by which the ready and simul-
taneous adjustment of the carriers is secured; the movable board carriers; means
for causing the proper entering of the tongues on the boards before they are
clamped together; and the employment of pressers for holding the boards and
preventing their bending, the parts capable of adjustment to operate properly with
any size or shape of box.
It will be understood that boxes of any size can be formed on this machine by
adjusting the slides and that the supports 17 can be moved toward the tops of the
carriers 12 for supporting the sides of shallow boxes thus obviating the necessity
of the operator putting his hand down between the slides.
The devices for causing the half and whole rotations of the operating shafts
may be as shown or of the usual variety, such as are used in drop presses and
similar machinery and operated by a treadle 98, shown in Figure 1, the connections
of which however, are not shown.
In the claims where I have used the term "slide" I do not desire to limit the
invention to a part that necessarily slides unless it is specified as adjustable, the
term being used to correspond with the one used in the Specification to designate
generally the parts 3, 3*, 4, and 4*.
