page_text: I WILLIAM PHILLIPS THOMPSON Fel Inst P. A, of the Agency for Foreign Patent
Solicitors, 6 Lord Street, Liverpool in the county of Lancaster, and 323 High
Holborn in the county of Middlesex, Civil Engineer, do hereby declare the nature
of the said invention for IMPROVEMENTS IN BOX MAKING MACHINES 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 machines employed in the manufacture of dove-tailed,
lock-joint, fingered, or other boxes of similar construction, for gluing and putting
the same together.
It consists essentially of a table provided with four racks for holding the ends
and sides, a rising and falling central table adapted to receive the bottoms from a
chute beneath, and raise the same to a level with the stationary table, a rack for
holding the bottoms near the outer end of said chute; four angular levers provided
with cross-heads adapted to take the sides and ends one at a time from their
respective racks carry them into position and & form the box upon the central
movable table which lifts the bottoin into position from below; a swinging arm to
take the bottoms one by one from their racks and deposit them in position upon
the movable table, together with a device for gluing and mechanism for adjusting
the machine for making boxes of different sizos.
The objects of the invention are
First Economy of time and expense in the manufacture of boxes of this
class, and
Second Accuracy and uniformity of work,

page_text: heads CC. Fig 8 is a vertical cross section of a cross-head C ou the line I (Fig 1)
Fig 9 is a longitudinal vertical section of the same on the line 22 (Fig 1) Figs 10.
11. 12. 15. and 10 are details, and Figs 13 and 14 illustrate the method of cutting
the pieces and of putting the same together.
A is an iron table supported by legs M M resting upon base T It has at the
centre a quadrangular opening which is exactly filled by the table D when the
same is in its upper position.
To table A are secured the two stationary dove-tailed ways H H, which meet at
right angles at one corner of the central opening; and the two adjustable dove-
tailed ways H H upon which several ways the cross heads C C C are adapted to
be moved back and forth between the racks N N N and central opening in the
tablo A. The cross-heads C C are channeled to fit the dove-tailed ways H H and
are provided with gibs o o to take up wear (Fig 8). They are also furnished with
the standards h¹ in which the small telescoping shafts p p bearing the arms & k¹
have the bearings.
To cause both segments of the small shafts p p to turn together and thereby
preserve the parallelism of the arms the smaller segments are grooved to
receive lugs projecting from the inner sides of the tubular segments in which they
freely slide, (Fig. 10). The standards ¹¹ rise from base blocks P P which slido
in channels formed in cross heads C C at right angles to ways H H, so as to permit
of the lateral adjustment of the arms for boards or pieces of different lengths.
When properly adjusted the blocks P P with their standards h¹ h¹ and arms k¹ k¹
are held firmly in position by means of the clamps and screws gg. To the larger
ends of shafts p p just outside of the fixed standards h h are secured the small
cranks 8s which are provided at their ends with small wheels or rollers adapted to
run upon the tracks F F'.
The movable ways H H have flanges q q formed upon their under sides and
adapted to slide in grooves cut in table A: they are advanced toward, or withdrawn
from tlie centre of the table by means of the long liand screws vv passing through
threaded eyes in the blocks w w which are bolted to said ways through the slots in
table A in which they slide (Figs 2 and 9).
They are held in place when properly adjusted by means of the set-screws z z.
BBB are angular levers pivoted at their angles to the bed T near the middle of
its four sides. The longer arms of said levers extend upward and are connected
with the cross-heads C C by the threaded bars J J¹ while the shorter arms extend
underneath the machine, and are connected near its centre with the cross-head U,
which moves up and down upon ways in the slotted standard V.
The cross-head U is connected by the pitman X with the large gear wheel W
which is keyed to shaft Y and driven by the small gear wheel or pinion meshing
therewith, and keyed to the driving shaft R, which is also provided with the
heavy balance-wheel S and with the fixed and loose pulleys t t (Figs 2, 3, and 4).
The levers B B are forked at their upper ends, between the limbs of which the
collars I, I', upon the threaded bars J J¹ are pivoted.
The collars II are adjusted, and held in position by means of the set nuts a a on
each side of them The bars J'J' are made longer than the others, and are threaded
'almost their entire length, and provided with the hand wheels z. z. which are
secured upon, and turn freely in, the collars 1¹ I' as shown in Figs 2, 3, and 11.
By means of this device the bars J' J¹ may bo lengthened or shortened between
the levers BB and cross-heads CC to correspond with the advancing or withdrawing
of the ways H¹ H¹ and track F¹ F¹.
The inner ends of the ways H H. are provided with acute angled corners E E'.
At the angle formed by the meeting of the stationary ways H H the fixed corner E
is 'raised.
The corners E¹ E¹ are raised upon the ways H'H' and are each adjustable with
them in a single direction. The corner E" is raised upon the inner end of the bar K
which is grooved to slide on a way raised on the right angled plate L (Figs 1
and 3), which has a flange on its under face near the inner edge adapted to move

page_text: at right angles to bar K in a groove cut in table A. The bar K is moved longi-
tudinally by means of the hand wheel while it is moved laterally at right angles
to its longitudinal movement by means of the hand wheel m. By this device the
corner E may be accurately adjusted in two directions at right angles to each
other.
"
When properly adjusted the corner E" is held in position by the slotted clamp ƒ
pivoted at one end to bar K and resting at the other end upon table A; and by
the set screw m passing through the slot in clamp f into table A, (Figs 1 and 3).
Four adjustable racks N N are raised upon supports bb from table A in such
positions that the arms on cross-heads CC come directly underneath the same
at the outer limits of the travel of said cross-heads. Each of the racks N N is
provided with the fixed upright guides uu, the adjustable upright guides cc,
raised upon the transversely sliding arms O O, the horizontal arms or supports d d
upon which the sides or ends aro piled one above the other, and with the gauges e e,
which have long slotted feet by means of which they are secured to the outer sides
of the racks N N by thumb nuts and bolts e' e' passing through the slots in said
fect and racks, By this method of attachment the gauges e e are made adjustable
in two directions. Tho guides c c and the supports d' d' are attached to arms 0 0
and are adjustable therewith. The broad right angled shanks of the arms 0 0
are secured to the racks N N by thumb nuts and bolts n n passing through the
same, the slots in said racks permitting of the lateral adjustment of the arms
without removing the bolts.
G is a curved chute composed of bars jj leading from one corner of the machine
to the side of the table D, and lying in the same horizontal plane therewith, when
said table is at the lower limit of its travel.
B is a swinging arm secured to the small vertical shaft a¹, which has bearings
in table A and in the cross bar A¹ and is at the centre of a circle of which the
chute G forms an arc.
•
It extends just underneath the chute G to the outer edge thereof, and is provided
at the end and between the bars jj with the counterbalanced pivoted fingers c¹ c' c¹,
the tips of which rise in front above the top of the chute and are adjustable in
height by means of the thumb screws b' b¹ b¹. The outer finger c¹ projects a little
in advance of the others, so as to prevent the bottoms from being thrown out of
position by the centrifugal tendency of the swinging arm B
The rod D' connects said arm Bi with the lever B, (on the opposite side of the
machine) from which it gets its motion.
C' is an upright rack secured directly above the chute G to table A, which is cut
away to receive it, and to allow for the filling of the same with box bottoms. It
extends downwards nearly to the top of the chute, and is provided at its outer
edge with the right angled flange f¹ which confines the bottoms at the outer ends.
d is an adjustable upright gauge secured by means of a collar and thumb-screw to
one of the bars jj, and is a vertical gauge secured to table A by means of its
long slotted foot and a thumb screw passing through the same into said table
(Figs 1 and 2).
E is a small horizontal arm secured to the shaft a¹ above the arm B¹ and
extending nearly to the outer edge of chute G.
It is pivoted to the broad shank g' between the two pins o¹ o¹ which permit it to
swing between them independently of shaft a¹. A spring presses the arm
against the pin o' nearest the arm B'. By means of this device the arm B¹ is
permitted to swing out to the outer end of the chute G while the movement of the
arm E is arrested by the rack C¹ against which it strikes. It is necessary to
place the arm E¹ thus near the arm B¹ so that it will clear the table D as it rises
and the arms recede (Fig 4).
The table moves up and down upon the ways m' m' raised upon the standards V
and Q and it is supported by the vertical rod G₁ which slides freely through a
perforated ear in the bracket K¹. L' is a cam set upon shaft Y. M' is an angular
lever pivoted at its upwardly turned angle to a bracket secured to the standard Q

page_text: it is provided at the end of the short arm with the small wheel or roller p² which
rolls upon the edge of the cam L' as the latter is rotated.
The end of the long arm of the lever M¹ is connected with the rod G¹ by the
bar 9. The cain L¹ is so shaped and set upon shaft Y as to raise the table D to a
level with table A just as the cross-heads CC approach bringing the sides and ends
of a box from racks N N, and to hold the same in that position until the box is
formed, when it allows the table to descend by its own weight till it comes to the
same level with the chute G in which latter position it is held while the approaching
arm Eremoves the box formed, and the arm B' deposits thereon another bottom
brought from the rack C at the end of chuto G (Figs 3 and 4).
In order to adjust the height of the table D very accurately there is inserted in
the lower end of the connecting bar q¹ a small set-screw 8¹ which presses against a
small block upon which the bolt ¹ rests (Fig 3) by turning the screw 8' in or out,
the table D may be raised or lowered very slightly.
The ends of the side levers B B extending underneath the machine are connected
with the cross-head U by means of the bars N' N¹ (Fig 12). The lever B which
passes through the slot in the standard V, is connected with the cross-head U by
the bar O pivoted to said lever at n point nearly underneath the cross-licad. In
order that both the end levers B B may have precisely the saine movement, the
ends of their lower limbs are joined by the bars P₁ P' pivoted thereto and to ench
other in the form of an inverted V, the apex of which is connected with the bar O'
by, the bar Q which causes said apex to travel in a nearly vertical and straight
line (Fig 3).
The upper ends of the sido guides u u are formed at the top with inwardly
projecting horizontal arms from which depend the light rods t¹t pivoted thereto
and provided with the retracting springs u¹ u¹ so as to meet the boards carried by
the cross-heads C C and prevent them from tipping forward as they come to a
perpendicular (Fig 2).
The arins on cross-heads C C are turned up at their front ends into small
hooks eel and are cut down upon their faces to receive the long sliding feet v₁ v
which have downwardly projecting slotted ears w¹ w by which they are secured to
said arms and kept in their proper positions.
The feet vviare dove-tailed and form ways for the channeled blocks i i to slide
thereon and slotted to receive the small dogs or spring catches a¹×¹.
When properly adjusted the blocks ii are fixed in position by set screws 2¹¹.
all all are small levers pivoted near their centres to short rearwardly projecting
Blanks of the arms k¹ the lower ends of the levers a" all are connected with the
tips of ears w¹ w¹ by small rods bb, the front ends of which are connected with the
armisk near their front ends by the spiral springs c c which draw the feet v' v¹
forward against the shoulders formed by the elevated front ends of said arms kk'.
The upper faces of the blocks ii and of the arinsk¹ just to the rear of their
terminal hooks, lie in the same plane and are so adjusted as to pass under the
racks N N in the same plane with the upper faces of the supports & d, or a trifle
below it as shown in Figs 5 and 6.
As the tracks FF1 approach the centre of the machine they are curved down-
ward, as shown in Figs 2 and 5 to permit the cranks 88 with arms to come to
a perpendicular; and at the inner ends they are raised so as to trip the cranks and
throw the terminal hooks on arms back of the faces of standards h h¹, and
thereby release the board carried by said arms at the bottom and allow the same
to be brought snugly against table A by springs c" c" acting through the dogs x¹¹
on the upper edge of said board.
Instead of raising the front ends of the tracks F F¹ for the purposes above
described, the device shown in Fig 5 may be used, consisting of an upturned sliding
hook having a right angled slotted shank g overhanging the side of the
track F and secured thereto in such manner as to allow it to move freely back and
forth a short distance upon said track.

page_text: is a strong spiral spring attached at one end to an car on the shank g¹¹ and
at the other to the side of track F' at a point near rack N. The hook f" is shaped
to receive the small roller at the end of crank 8, and so arranged as to trip the
same as the arms k k¹ come to a perpendicular, and to withdraw the hooks el ell
from the boards held between them and dogs x¹ x¹.
are side or end plates resting upon supports à & and secured, one to the
end guard c and adjustable therewith and the other to the end guard u, for the
purpose of holding the boards accurately and firmly in the proper position to be
withdrawn by the arms k k'.
R' R' are gluing rollers journalled in the fountains S' S¹ which are attached by
means of brackets to the end racks N N in pairs, one of each pair to the front
of the racks N N and the other to the front of arms 0 0, so as to be adjusted
therewith. The fountains S¹ S' are formed into sleeves in the rear to receive the
vertical standards of brackets "1", upon which they freely slide and from which
they can be readily removed when the machine is not in use. A glue pot T¹
supported upon table A, supplies the fountains S' S₁ through the pipe U₁ connected
with each fountain by the flexible tubes n" n", which permit of the vertical
movement of the fountains and of the lateral adjustment of the fountain attached
to the arm O. The glue pot T' is formed with double walls enclosing a space into
which steam is admitted through pipo m¹. By this means glue may be kept hot
and in a liquid state.
Cog teeth o oll are formed upon the peripheries of the rollers R¹ R' which are
adapted to mesh into the recesses of the fingered ends of the boards as they emerge
from the racks N N and are hung sufficiently low to be raised and sustained by
the ends as they pass under the same as seen in Figs 5, 6, and 7.
The fountains S¹ S₁ are enclosed at the bottom by the rollers R' R¹, so as to
prevent the escape of glue except when the latter are in motion.
When however the rollers R¹ R¹ are rotating a small quantity of the liquid glue
is fed down and out through the bottom of the fountains S' S₁ by the teeth o oll
of the rulls R¹ R' and deposited upon and between the fingers of the boards
preparatory to their being united together in the construction of a box.
W, X and Y, (Figs 13 and 14) are end sido and bottom pieces showing tho
preferable method of cutting the same for the new machine.
The new machine operates as follows :—
The racks N N are adjusted for making boxes of the desirable size, by placing a
pile of sides and ends in their proper places against the fixed guides uu in each
rack, and then bringing the guides cc on arms 00 and the gauges are close up to
their exposed sides, and securing them in position by means of the thumb screws e¹
and n¹.
A pile of bottoms is placed in the rack C¹ snugly in the corner formed by said
rack and the flange f, the gauges d" and i are then brought close up to the
remaining sides and set by their thumb screws in position. The cross-heads C Care
adjusted by setting the blocks P P so that the arms will come a little inside
of the fingered ends of the pieces in racks N N and are then secured in position by
the clamps and screws 9 g. The corners E' E' are set by means of the hand
screws the corner E' at the end of the central opening in table A at a distance
from fixed corner E' equal to the length of the ends of the box, and the corner Ev
at the side of said opening at a distance from said fixed corner E equal to the
length of the sides in the box.
The corner E" is then set by means of the hand wheels and m so that its apex
will be at the angle of a rectangle of which the corners E E' E' mark the remaining
three angles.
The corners E' E' are secured in position by means of the set screws 32 and the
corner El by means of clamp fand set screw n. In adjusting the corners E' E'
as just described, the dove-tailed ways H'H' upon which said corners are raised
are at the same time adjusted for the proper travel of their cross-heads CC, the
faces of the standards of which are made to advance to the side and end of

page_text: the rectangle included between the corners E E' E' and E" by lengthening or
shortening the bars J¹ J' connecting said cross-heads with levers B B, an adjustment
readily made by means of the hand screws Z Z turning in sleeves I'I' to which
the levers B B are pivoted as herein before described. Steam is admitted into the
space surrounding the glue pot T through pipe m", and the glue thereby reduced
to a liquid stato and fed into fountains S¹ S₁ through pipe U₁ and flexible
tubes nn, when it is readily applied to the ends of the boxes as they emerge
from their racks N N by means of the cog teeth o o" on rollers R¹ R¹.
The racks N N and C¹, having been supplied with ends, sides and bottoms, the
machine is set in motion by means of power applied thereto through fixed pulley t.
The cross-heads CC now travel back and forth between the central opening in
table A and the racks N N, taking at each journey a side and end from the
bottom of the pile in each rack, and carrying the same to a perpendicular position
at the centre of the machine where they are forced together about a bottom raised
to position by the table D.
The operation of each of the cross-heads C C being the same, it will be sufficient
to describe one in detail; for instance, the one shown in Fig 5.
As the arms' pass under the pile of ends the dogs a¹¹ strike the bottom
of the pile and are forced into the blocks ii and just before the hooks el ell on
arms come to the inner edge of the lowest end of the pile the tops of the
levers all all strike against the rear side of the rack N as shown by dotted lines
in Fig 6, the lower ends of the levers all all are thrown outward and through the
connecting rod 6" 6" force the feet v¹¹ with their blocks ii back on the faces of
the armisk so that the dogs a¹¹ are carried a little to the rear of the pile of
ends and are forced by springs (shown in Fig 15) up out of the blocks ii;
the cross-head now advances, and the levers all all leave the side of rack N,
thereby releasing the feet v v¹ which are drawn forward by the springs cl" c¹ till
the dogs xx¹ engage with the rear edge of the bottom end, and grasp the samne
firmly between thein and the terminal hooks ell ell.
As the end emerges from the pile, it is carried underneath the gluing rollers R¹ R¹,
which, with the fountains S₁ S₁ are slightly raised so that their weight is sustained
upon the same, as the rollers are rotated and the glue is spread by the cog
teeth o ol over its fringed ends. The cog teeth o o" are filled with glue as
they pass through the fountains S' S', but when the rollers R' R' are at rest, the
rollers prevent the escape of glue from the bottom of said fountain. As the cross-
head C advances and the roller or crank S passes over the depressed portion of the
track F', the arms kk assume a perpendicular position and the end carried by
them meets one of the rods t¹ which prevents it from tipping forward in case the
dogs loose their hold upon its upper edge. The wheel on crank S meets the
raised portion of the track F1 or the hook fil by which the arms kk' are turned
back and the terminal hooks el ell drawn back off the faco of the standards h h¹,
releasing the lower end, and allowing it to be brought down suddenly against the
tablo A.
As the end passes the corners E E¹ it meets the sides brought by the cross-
heads CC from the side racks N N and the bottom raised into position by the
tablo D, and they are forced together in the manner shown in Fig 14; the
operation is simultaneous and the same at both ends of the machine. Tho glue
spread upon the ends is forced into the finger joints as the pieces come together,
and the four corners are thereby effectually formed and glued at one operation.
The table D now descends with its box which is removed by the arm E¹ while the
arm B brings another bottom from rack C¹ and deposits it upon said table 1) for
the next box; the operation just described is repeated and at each revolution of
the wheel Wn box is glued and put together.
As the arms B' press under the pile of bottoms in rack C¹ the tips of the
fingers c¹ c¹ c' are turned down; but as they emerge at the rear of the pile they
assume their original position by reason of the counterbalancing weight of their
rear ends.

page_text: Instead of applying the gluing device to the end racks, it may be applied to the
ide racks, or to both end and side racks, although it is preferable to attach it to.
he end racks alone.
The table D and the swinging arm B', and their connections, may be dispensed with
nd the table A made without a central opening whenever it is desired to attach
he bottom at a separate operation by nails, or by means other than those
lescribed.
