page_text: I, HORACE INMAX, of 11, Whitecross Street, London, E.C., Manufacturer, do
hereby declare the nature of this invention to be as follows;-
This invention relates to apparatus for covering boxes with paper cloth or
the like and consists in certain improvements in that class of apparatus illustrated
in my prior Specification No. 709197.
According to this invention the main frame of the machine consists of a table
and suitable supports or legs the table having bearings for the main driving shaft
upon the outer end of which is a grooved pulley to which a continuous rotation
is imparted during the operation of the machine.
A secondary or supplementary driving shaft turns in bearings at one side of
the machine, from which shaft the box holder or box form is driven through
the medium of devices hereinafter described.
T'pon a supplemental frame above the table are supported one or more reels
for one or more strips of paper, a paste trough in which turns freely a paste
roller and a series of bars and fingers adjustable to guide the different pasted
strips, adjustable guide rods, and beneath the fingers is a trough supported from
vertical side bars in position to receive any paste drippings from the strips pass-
ing over the rods and adjacent to the fingers.
The box form is connected to one part of a clutch consisting of said part and
a second part locked at times together by a locking pin on a spring and at times
unlocked to permit a temporary arrest of the first part during the revolution of
the second part under the action of an internal spring and limited by the play
of a stop pin in a slot of the second part. In the present construction, there is
a bracket with a projection having an inclined edge with which the end of the
spring on the locking pin makes contact, the spring and locking pin being thereby
withdrawn at proper intervals.
The second part of the clutch is secured to a shaft turning in bearings upon
a bracket and provided with a worm wheel engaging a worm upon the side shaft
of the machine the end of which has its bearings in the said bracket.
The bracket is at the end of a tube through which the shaft extends, and this
tube also passes through a second bracket secured to the frame of the machine
and adjustable longitudinally so as to carry the box-form to a greater or less
extent from the end of the main frame, as is necessary when the sizes of the box-
forms are changed, and as is also necessary when in operations upon different
forms and sizes of boxes, it is requisite to expose the paper with the paste upon
it for a longer or shorter time before applying it to the box.
In order to permit the ready adjustment of the tube carrying with it the shaft
and at the same secure it firmly in position so that it will not be liable to become
loose, one side of the tube is split to form a longitudinal channel with beveled
edges, and the second bracket is recessed to receive a U-shaped key having a

page_text: V-shaped inner edge entering the recess and a set screw bears against this key,
and by forcing the latter inward the split tube is expanded so as to become firmly
wedged in the bracket.
A similar device is made use of for securing an adjustable cutter frame movably
upon the tube. This frame is supported by a collar sliding upon the tube and
provided with a key and set screw corresponding to these parts supported by the
second bracket.
The frame has a vertical standard upon which is secured adjustably a hub
from which extends the lower horizontal knife of the cutter, and upon a pin
swings the upper knife. This upper knife instead of being of stiff rigid plate
as heretofore, is made light and flexible and is stiffened by means of a brace
which tends to hold it in shape and permits it to be slightly bowed so as to insure
a good shearing cut against the lower knife. The brace may consist of a screw
rod extending through two eyes and provided with nuts by means of which it
may be tightened.
The upper knife is vibrated from a rack shaft the forward end of which turns
in a projection of the first bracket and being provided with an arm carrying a
friction roll and arranged to be struck by a pin extending from the second part
of the clutch. The contact of the pin with the arm rocks the shaft and thereby
operates the upper knife through the medium of an arm and connection rod
adjustably attached to the heel of the knife by a pin. Preferably the rod has
a series of openings to permit of desirable adjustments. A spring connected
to an arm extending from the rock shaft swings the latter in one direction to lift
the knife.
Difficulties have at times been experienced with this class of machines owing
to the uniform speed of operation of the parts, which was the same in covering
large boxes as in covering small ones, and according to this invention means
are provided whereby the speed of operations of the working parts may be
changed at will, and whereby also the transition from a state of rest to a state
of motion and rice versa may be effected without varying the operation or move-
ments of the main driving shaft. To this end, at one end of the driving shaft is
placed a friction dise which engages with a friction pulley upon the side shaft
which shaft and pulley are provided with slots and a feather to permit the adjust-
ment of the pulley upon the shaft and also to permit the shaft to be moved longi-
tudinally independently of the pulley when the tube is carried inward or outward.
Any suitable canier and retaining means may be employed. For instance, a
movable bracket has arms straddling the pulley and is perforated for the passage
of the shaft and extends into a slot in a box bolted to one side of the frame of
the machine. A set screw passes through the slot of the bracket and when
loosened serves as a ready means of setting the pulley at any required distance
from the centre of the main driving disc to determine the speed of the operating
parts and then by tightening the said screw the bracket is secured in place.
The operating parts may be started and stopped less abruptly than by the use
of ordinary gearing by shifting the main driving disc. This may be done in
different ways, say by giving the main driving shaft a slight longitudinal play
in its bearings and providing it with a collar against which bears a spring tend-
ing to keep the gears apart. To the underside of the table is bolted a collar
having inclined teeth corresponding to the inclined teeth upon a sleeve mounted
loosely on the driving shaft. By turning the sleeve in one direction it will
ride upwards upon the inclined faces of the collar carried by the table and bear-
ing on the collar carried by the shaft will press the driving disc against the
driving pulley.
The sleeve is turned to effect the above described results by means of a treadle
pivoted to one of the legs of the frame, and a cord suitably guided and connected
to the treadle, and an arm extending from the sleeve. In order to adapt these
operations to the varving adiustments of the box form at different distances from
the frame, the treadle is made extensible in any suitable manner. For instance,

page_text: it is in two parts, the first part extending into a box carried on the other part
and adjustable therein and secured by a set screw. In order that it may not be
necessary for the operator to maintain his foot upon the treadle a pawl is pivoted
to the frame with a shoulder which engages a projecting portion of the treadle
as soon as the latter is depressed and holds it in place.
The pawl may be withdrawn so as to arrest the machine as the paper passing
to the box upon the box-form is severed. A simple construction to this end
consists of an arm extending from a pawl having a lug with a recess for the pas-
sage of a rod connected at the upper end to the arm of the knife rock shaft and
threaded at the lower end to receive a nut. The nut is adjusted to permit a
certain amount of lost motion so that the pawl is only shifted as the severing of
the sheet is completed.
When the treadle is depressed the main driving disc is brought against the
driving pulley and the box form starts its rotation. This will continue until
one complete rotation is made when the contact of the pins on the clutch and
rocking of the lever will lift the arm on the knife rock shaft and rod operating
the arm and pawl until the nut strikes the arm and carries the detent away from
the treadle which will at once rise as the spring carries the main driving dise
from the driving pulley and arrests the movements of the parts driven from said
pulley.
By adjusting the nut the moment of releasing the treadle can be accurately
determined.
It will be evident that any suitable clutch gears or mechanism may be employed
for starting and stopping the box form shaft. It will also be evident that any
suitable adjustable contact pin may be substituted for the nut to operate the
arm and detent.
In addition to the guide rods and fingers set forth in the prior specification it
is proposed to employ two additional adjustable rods with upturned ends so
arranged as to bear upon the edges of different strips of paper and serve to
properly guide the same.

Improvements in and connected with Box Covering Machines.
I, HORACE INMAN, of 11, Whitecross Street, London, E.C., Manufacturer, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the follow-
ing statement:--
This invention relates to apparatus for covering boxes with paper cloth or the
like and consists in certain improvements in that class of apparatus illustrated
in the Specification to Letters Patent No. 7091 of 1897 as fully set forth herein-
after and as illustrated in the accompanying drawings, in which:--
Fig. 1 is a side elevation of my improved apparatus:
Fig. 2 is a transverse section on the line 22 Fig. 1:
Fig. 3, a detached elevation of a part of the apparatus connected with the guide

page_text: Fig. 5 is a detached view of the paper cutter and connected parts;
Fig. 6, an edge view of the parts shown in Fig. 5, with the frame in part
section;
Fig. 7, a detached sectional view of one of the clamping devices;
Fig. 8, a detached sectional view showing the box form and some of the con-
nected parts;
Fig. 9, a section on the line 8-8, Fig. 8;
Fig. 10, a section on the line 10-10, Fig. 8.
Fig. 1 is on a smaller scale than the other figures.
The main frame of the machine consists of a table C and suitable supports
or legs B, the table having bearings for the main driving shaft q Fig. 2 upon
the outer end of which is a grooved pulley to which a continuous rotation is
imparted during the operation of the machine.
A secondary or supplementary driving shaft a turns in bearings at one side
of the machine, from which shaft u the box holder or box form A is driven
through the medium of devices hereinafter described.
Upon a supplemental frame E above the table Care supported one or more
reels R for one or more strips of paper and a paste trough G in which turns freely
a paste roller I and a series of bars and fingers kk' m adjustable to guide the
different pasted strips, together with adjustable guide rods a a; and beneath the
fingers m is a trough G supported from vertical side bars nn in position to receive
any paste drippings from the strips passing over the rods and adjacent to the
fingers.
The box form A is connected to the part 11 cf a clutch S consisting of said
part 11 and a part 12 locked at times together by a locking pin 14 on a spring 15
Fig. 8 and at times unlocked to permit a temporary arrest of the part 11 during
the revolution of the part 12 under the action of an internal spring 25 and limited
by the play of a stop pin 18 in a slot 19 of the part 12 as described in the before
mentioned specification. In the present construction there is a bracket 6 with
a projection 7 having an inclined edge with which the end of the spring 15 makes
contact, the spring and locking pin 14 being thereby withdrawn at proper
intervals.
The part 12 is secured to a shaft 8 turning in bearings upon a bracket D and
provided with a worm wheel 9 engaging a worm 5 upon the shaft u the end
of which has its bearings in the said bracket D.
The bracket D is at the end of a tube I through which the shaft u extends,
and this tube also passes through a second bracket 1 secured to the frame of
the machine and adjustable longitudinally so as to carry the box form to a greater
or less extent from the end of the main frame, as is necessary when the sizes of
the box forms are changed, and as it also necessary when in operations upon
different forms and sizes of boxes, it is requisite to expose the paper with the
paste upon it for a longer or shorter time before applying it to the box.
In order to permit the ready adjustment of the tube 1 carrying with it the
shaft and at the same time secure it firmly in position so that it will not be
liable to become loose one side of the tube is split to form a longitudinal channel 2,
Fig. 7, with beveled edges and the bracket is recessed to receive a U-shaped
key having a V-shaped inner edge entering the recess 2 Fig. 5, and a set
screw bears against this key and by forcing the latter inward the split tube 1
is expanded so as to become firmly wedged in the bracket.
A similar device is made use of for securing an adjustable cutter frame T
movably upon the tube 1. This frame T is supported by a collar 12 sliding upon
the tube and provided with a key w and set screw h corresponding to these
parts supported by the bracket ])¹.
The fiame T has a vertical standard 16 upon which is secured adjustably a
hub 17 from which extends the lower horizontal knife 36 of the cutter, and upon
a pin 35 swings the upper knife 34. This knife 34 instead of being of stiff rigid
plate as heretofore, is made light and flexible and is stiffened by means of a

page_text: brace which tends to hold it in shape and permits it to be slightly bowed so as
to insure a good shearing cut against the lower knife. The brace may consist
of a screw rod 28 extending through two eyes 26, 27 and provided with nuts 281
by means of which it may be tightened.
The upper knite 4 is vibrated from a rock shaft the forward end of which
turns in a projection of the bracket 1 Fig. 8 and is provided with an arm 29
carrying a friction roll and arranged to be struck by a pin 30 extending from the
clutch S. The contact of the pin 30 with the arm 29 rocks the shaft F and
thereby operates the upper knite 34 through the medium of an arm 36 and con
nection rod 37 adjustably attached to the heel of the knife by a pin 38. Prefer-
ably the rod 37 has a series of openings to permit of desirable adjustments. A
spring 40 connected to an arm 41 extending from the shaft F swings the latter
in one direction to lift the knife.
Difficulties have at times been experienced with this class of machines owing to
the uniform speed of operation of the parts, which was the same in covering
large boxes as in covering small ones, and according to this invention means are
provided whereby the speed of operations of the working parts may be changed
at will, and whereby also the transition from a state of rest to a state of motion
and vice versa may be effected without va ying the operation or movements of
the main driving shaft. To this end at one end of the driving shaft is placed a
friction disc Figs. 1 and 2 which engages with a friction pulley 2 upon the
shaft which shaft and pulley are provided with slots and a feather to permit
the adjustment of the pulley upon the shaft and also to permit the shaft to
be moved longitudinally independently of the pulley when the tube 1 is carried
inward or outward. Any suitable carrier and retaining means may be employed.
For instance, a movable bracket II has arms straddling the pulley and is per-
forated for the passage of the shaft and extends into a slot Fig. 4 in a box L
bolted to one side of the frame of the machine. A set screw 43 passes through
the slot of the box L and when loosened serves as a ready means of setting the
pulley at any required distance from the centre of the disc g' to determine
the speed of the operating parts and then by tightening the said screw the bracket
is secured in place.
The operating parts may be started and stopped less abruptly than by the use
of ordinary gearing by shifting the disc q'. This may be done in different ways,
as by giving the shaft q a slight longitudinal play in its bearings and providing
it with a collar 44 against which bears a spring 45 tending to keep the gears
apart. To the underside of the table C is bolted a collar 46 having inclined teeth
corresponding to the inclined teeth upon a sleeve 47 mounted loosely on the
shaft. By turning the sleeve 47 in one direction it will ride upwards upon
the inclined faces of the collar 46 and bearing on the collar 44 carried by the
shaft will press the disc ' against the pulley
The sleeve 47 is turned to effect the above described results by means of a
treadle P pivoted at 50 to one of the legs of the frame, and a cord 51 suitably
guided and connected to the treadle, and an arm 52 extending from the sleeve.
In order to adapt these operations to the varying adjustments of the box form at
different distances from the frame, the treadle is made extensible in any suitable
manner. For instance, it is in two parts 52, 53, the first part extending into a
box carried on the other part 5 and adjustable therein and secured by a set
screw 54. In order that it may not be necessary for the operator to maintain his
foot upon the treadle, a pawl 55 is pivoted to the frame with a shoulder e which
engages a projecting portion of the treadle as soon as the latter is pressed and
holds it in place.
The pawl may be withdrawn so as to arrest the machine as the paper passing
to the box upon the box form is severed. A simple construction to this end con-
sists of an arm 56 extending from the pawl having a lug with a recess for the
passage of a rod 57 connected at the upper end to the arm 41 of the shaft F and
threaded at the lower end to receive a nut 58. The nut is adjusted to permit a

page_text: certain amount of lost motion so that the pawl is only shifted as the severing of
the sheet is completed.
and
When the treadle is depressed the disc q is brought against the pulley
the box form starts its 10tation. This will continue until one complete rotation
is made when the contact of the pins on the clutch and 1orking of the shaft F
Fig. 8 will lift the arm 41 and rod 57 until the nut 58 strikes the arm 56 and
carries the detent 55 away from the treadle which will at once rise as the spring 45
carries the disc from the pulley and arrests the movements of the parts
driven from said pulley.
By adjusting the nut 58 the moment at which the treadle will be released can
be accurately determined.
It will be evident that any suitable clutch gears or mechanism may be em-
ployed for starting and stopping the box form shaft. It will also be evident
that any suitable adjustable contact pin may be substituted for the nut 58.
In addition to the guide rods and fingers set forth in the prior specification
it is proposed to employ two additional adjustable rods n²² Fig. 2 with upturned
ends so arranged as to bear upon the edges of different strips of paper and serve
to properly guide the same.
