page_text: description. O is an arm pivoted to a stud P on the side of the glue tank, and the
position of this stud may be changed by loosening the nut Q on the inside of the
glue tank, to give the arm O a horizontal or vertical or any intermediate position,
so that the location of the reels of paper which are supported upon a shaft R, which
ie fastened in the end of the arm O may be changed relative to the roller 1.
S, S¹ are two flanges which may be solid or made in the form of bars, as seen
clearly in Fig. 1, and which confine the paper laterally; they are adjustable on the
rod R by means of the set nuts T, T¹. U is a cross-rod or stiff. wire, the ends of
which are bent downwardly and pass through studs V and V on the sides of the
glue tank; the rod is fastened at any desired height by means of set screws W, WI,
so that any desired adjustment and tension of the paper may be acquired, for it
will be understood that as the paper rolls off from the reel or reels located upon
the shaft R, the lower the cross-rod U is, the sharper the deflection of the paper
will be, thus increasing its tension; and, also, that it will have greater bearing
upon or come in contact with a larger area of the glue roller I.
a is a cross-rod upon which are located guiding fingers which project down-
wardly (see Fig. 1) and act as guides for the paper by impinging upon the edges
thereof. These fingers are movable upon the bar a and may be clamped in any
desired position by small set nuts c. The bar is supported at one end only upon a
stud d which rests upon a lug e cast or otherwise formed upon the glue tank, so
that the paper can be swung under it quickly in preparing the machine for work.
is a small plate or table adapted to support a pan or other receptacle to catch
any adhesive material that may be squeezed out from between the papers. This
plate has a hub g upon its under side, which is bored so that it may slide upon
the rod E. This part of the apparatus is best seen in Fig. 3. At each side
of the plate fare two ears or lugs h, upon which are supported two uprights i, i¹
upon which, in turn, are supported, a cross-rod j having on opposite sides, liuks k, k¹
respectively, and 7 is a cross-bar which connects the upper ends of the uprights i, ¹
and upon this cross-bar are a series of guiding fingers m, m¹, m², m³. They are all
supported upon small hubs as shown, in which are threaded set screws n, n', n², n³.
These devices are used when two or more strips of paper are employed to cover
the boxes, the guiding fingers being properly located and manipulated to impinge
upon the edges of the several strips of paper, and to guide them all, as set forth in
the Specification to the Letters Patent of the United Kingdom granted to Horace
Inman, the 10th day of January 1888 No. 384 to which I refer for a detailed
description. It is not essential, however, that the paper guiding mechanism should
be of this particular character nor is it essential when a single strip of paper only
is used that guiding devices of any kind should be employed. The form illustrated,
however, has been found effective and valuable, and is, therefore, illustrated in
connection with this machine.
This shaft
O is a tubular sleeve grooved on one side as shown at p Fig. 5. It passes
through a rounded knob or upper end of the post D above the longitudinal rod or
shaft E and has formed with it, a shaft q upon one end of which is loosely mounted
a belt-wheel and on the other end, a bevelled gears Fig. 2 which meshes into
another bevelled gear t which is mounted upon a longitudinal shaft u.
is grooved as at v, and a feather on the inside of the hub of the bevelled gear t
engages with this groove, so as to have a spline effect to compel the rod u to turn
with the pinion, and yet allow the former to be moved longitudinally through the
pinion. The parts are contained within a yoke w on the end of the shaft and
are retained in position by it partly. a¹ (see Fig. 2) is an arm having a hub at
both ends as shown; one of them embraces the longitudinal rod E and the other
embraces a hollow rod 61 and set nuts c' and d' d' respectively clamp these parts in
their desired position, and yet permit longitudinal movement or adjustment of them
as the necessities of the work require; thus the machine as a whole, and also the
relation of its several parts to each other, can be adjusted as desired, to accomplish
the best results, in consideration of the character of the paper or adhesive material
being used, and the kind of work produced. Upon the hollow rod 6' are mounted

page_text: the cutters e¹, paper guiding fingers f¹ and box form support g¹, which is actuated
by suitable mechanism contained within a terminal portion 2 of the rod b'. These
cutting off devices may be of any desired construction. I, therefore, excepting as
specifically claimed, do not limit myself in regard to them. I shall, however,
hereinafter describe a special construction of cut off mechanism, which I prefer to
use in connection with this machine, and claim the same as part of the improvements
protected by this patent.
Referring to Fig. 2, 11 are paper guiding fingers set upon elastic spring supports
or brackets n which are suitably fastened to a sort of hub o², and the paper on its
way to the cutters, passes between and is supported by them, so that when it is cut
off by the action of the shears, the remaining end is supported by the lower finger,
and if the severed end should stick to the swinging blade of the shears by reason
of its becoming more or less smeared with adhesive material, and be carried
upwardly by the blade when it rises, the paper will then immediately strike against
the upper bar and be stripped off or pulled away from the swinging blade, and yet,
owing to the elasticity of these supporting devices, they will readily yield
somewhat to the pull of the paper, thus avoiding tearing of it, should the strain be
considerable.
is a cross-rod supported upon an upright gl which is fastened in the arm a¹ at
any desired height, and upon it, are paper guiding fingers which may be the
same as the fingers 6 already described."
The
Referring to the parts shown more particularly in Figs. 4, 5 and 6. They
illustrate devices whereby to a certain extent, the operator is not in control of the
machine. That is to say, after he starts the machine by pressure upon the pedal,
it continues to run irrespective of anything he may do, until the box upon the box
form has made one complete revolution and should be completely covered with the
covering or covering and trimming papers, with the result that not only are the
operators compelled to be active in their work of rubbing down and edging over
the covering papers, but also, there is no possibility of there being slack in the
covering papers, which is likely to occur to the detriment of the work, where
the machine can be stopped and started at any moment by the operator.
parts that effect this purpose are as follows: The driving wheel r has a recess A¹
in its hub, the peripheral surface of which is provided with a series of ratchet like
teeth B in the recesses between which works a pawl C which is pivoted as at D'
to an annular block E' which is keyed as at F¹ to the shaft q. The pawl C works
in a recess G¹ made in the block E' and a spring H₁ normally throws the pawl
outwardly into engagement with the teeth B. I is a pin which projects beyond
the surface of the block E. J¹ is a block or forging fastened by a set screw K¹
upon the exterior of the sleeve O¹ and it supports a pin L' which is normally
thrust to the right by a spring M1, but which can be forced rearwardly by a bell
crank N' which connects at 03 with the treadle. The bell crank is pivoted at Pi
to a lug projecting downwardly from the block J. Qis a swinging latch actuated
by spring R which, when the pin L' is retracted, swings across its retracted end
(as seen in Fig. 6, in which figure it is shown as in the act of passing across or
onto the end of the pin L') and becomes locked against outward movement by
entering a groove cut in the side of a projecting piu Si.
The operation of this part of the apparatus will be now recited, since it will
be more readily comprehended if given in immediate connection with the
description of the parts. It is as follows:-
The driving wheel as stated, is loose upon the shaft and when the pin L' is
in its inward position it engages with the pawl C₁ and lifts the same out of the
recess between the teeth B₁ in the hub of the driving wheel, so that its movement
is not conveyed to the shaft q. Now, therefore, to start the machine, the operator
presses upon the pedal which, through the instrumentality of the bell crank N'
retracts the pin L₁; the spring H' then immediately projects the pawl C' which
instantly engages with one or the other of the recesses between the teeth B' and
and the
thereupon the rotary movement of the wheel r is conveyed to the shaft

page_text: apparatus starts. Simultaneously with the withdrawal of the pin L' of the pedal, the
latch Q actuated by its spring R¹ passes across the retracted end of the pin L¹
so that it cannot again return into the path of the pawl C. Consequently what-
ever the operator may do will have no effect upon the movement of the machine.
The shaft will continue to revolve whether or not the pedal be pressed upon.
During the revolution of the parts, however, the pin which is fastened to it,
but projects beyond the face of the block E' is brought around until it engages
with a projecting thumb T¹ which forms part of the latch Q. As soon as this
takes place, that latch is forced outwardly against the action of its spring R¹ and
thereupon the pin L' is released and it immediately springs forwardly into the
path of the pawl C' which, however, at this stage of the movements, has passed
beyond that pin, so that it completes its revolution before it comes in contact
with the pin L', whereupon the impact of that pin against it lifts it from engage-
ment with the ratchet and as soon as that engagement is broken the shaft q stops,
and consequently, the entire machine stops, although the wheel continues to
revolve, and I prefer to construct and time the machine so that there shall be
these two revolutions of the driving wheel before the machine can be brought to
rest, because the "speeding" is somewhat improved by this arrangement. It is
not essential, however, that there shall be two revolutions, one will serve under
many circumstances as well.
Referring now to the special construction of the devices illustrated in Figs. 7, 8,
9 and 10, i.e., those relative to the paper cutting and box form rotating instru-
mentalities; they may be made, as before stated, in any preferred form.
One desirable construction is shown in Figs. 1 and 2. My preferred construction,
however, is shown in Figs. 7 to 10. The advantages which this form has over all
others, is that it is simple, short in space; its construction allows the cutter blade
to act nearer the box form, so that when desired, the covering paper can be cut
practically at the very corner of even a small box; also the two parts of the box
form head or rotating mechanism are actuated under this construction by a spiral
spring, which is better than a plate spring. I also apply a roller to the knife
actuating arm or lever which reduces friction, and under this construction, the
box form is clamped between two nuts on a spindle, thereby permitting a slight
lateral adjustment of the box form, which is sometimes very convenient, and also
makes the change of box form simple and easy.
Referring to the stated Drawings 7, 8, 9 and 10. In them, I have given the
parts numerals, as the means of reference, instead of letters so as to avoid confusion
with the other figures.
1 is the sleeve of the driving shaft, which corresponds to the letter b' in the
other drawings, 2 illustrates the driving shaft which corresponds to the letter u.
3 is an arm fastened by set screw 4 to the main supporting shaft or bar E of the
machine. All of the operative parts in this construction are supported upon the
arm E. 5 is a globular, brass casing, which encloses the driving mechanism for
the box form, which comprises a mitre gear 6 which meshes into another mitre
gear 7, which is fast upon the cross shaft 8. This cross shaft is journaled in two
bearings 9, 9, in each side of the globular extremity 5, and the lower arc of the
mitre gears run in oil which is placed within the globular casing, so that it is not
only a protection against accident, arising from these mitre gears, but also serves
as an oil cup for the mechanism contained within it. Upon the shaft 8 are
arranged the two parts of the box form clutch mechanism, so called by me; one
part 10 is fast to the shaft, and the other part 11 has a central extension which
enters a central cavity in the part 10, as shown. (For the purpose of making this
part of the drawings more clear, since they are necessarily somewhat complicated,
I cross hatch the part 10 with light section lines and the part 11, with heavy
section lines.) The part 11 is held to the part 10 by screws 12, 12 (see Fig. 9)
which pass through the walls of the part 10, and enter an annular groove 13 in
the part 11 (see Fig. 7). The part 10 is provided with a pin 14, which is fastened
to a spring 15, and which extends through the part 10 from side to side, projecting

page_text: :-
beyond it, as shown in Fig. 8, and enters a hole 16, which is made at one end of
a slot 17 Fig. 10 in the part 11, so that when the parts are in their normal position,
the spring 15 holds the pin 14 in the hole 16 in the part 11, consequently the
two halves of the clutch are locked together, when, however, the spring is retracted
carrying the pin 14 backward with it, then the end again passes through the
slot 17, thus giving slight movement to the two parts of the clutch relative to one
another, and for the purpose of securing the proper movement of one portion of
the clutch relative to the other, the part 11 has a pin 18 rigidly attached to it,
which passes through a slot 19 made entirely through the part 10 (see Fig. 7).
The end of the pin 18 (see Fig. 8) projects laterally beyond the side of the
part 10, so that, in the revolution of these parts (which is indicated by the arrows
upon Fig. 9) it comes in contact with a vertically sliding stop 20 made in the form
of a staple, and with which engages a cam 21 fast on the shaft 8. 22 is an
inclined surface made upon a suitable part of the machine, with which the
extremity 23 of the spring 15 engages at the proper time. The operation is as
follows When the pin 18 comes against the staple 20, the revolution of the
piece 11 is arrested, and during the time it is at rest, the pin 14 (which
has just previously been withdrawn by the engagement of the extended end of
the spring 15 against the inclined surface 22) is travelling through the slot 17
in the part 11. The result of the above action is that for a brief period the box
form which is attached to the part 11, does not revolve, nor does the paper travel
through the machine, and the adjustment and "timing. of the parts is such, that
during this brief period of rest, the cutters are operated by the mechanism already
described, and the covering papers are cut off square, that is, at right angles.
Meanwhile, however, the cam 21, which is fast upon the shaft 8, and, of course,
under continuous revolution, engages with the upper, or other suitable part of the
sliding stop 20, and depresses it until it attains a plane so low, as not to further
engage with the pin 18. Whereupon the spring 24 which, as already stated is
housed in an interior recess between the two parts 10 and 11, as shown in Fig. 10,
and which abuts at the two ends against stops upon the said parts respectively,
immediately acts upon the movable part 11, returning it again to its normal
position, and the pin 14 likewise immediately returns to its normal position, since
the terminal 23 of the spring 15 which carries it, has by this time passed beyond
the deflecting surface 22; thus all of the parts referred to again assume their
initial position ready for a repetition of the operation, which is continued in a
manner now well understood, the covered box being removed from the box form,
and an uncovered box blank applied thereto.
"
By these instrumentalities, I secure a peculiarly valuable result, which has never
been attained before, so far as I am aware; that is to say, the parts all operating
automatically, and with exact positiveness, I am enabled, by proper adjustment of
the parts, to cause the severed end of the covering paper or papers to come at a
corner of the box, which is a desirable feature, because when the paper terminates
at a corner, the seam or joint is hardly discernible, even with careful scrutiny. In
all other machines known to me, the lost motion is such as to vary the place of
severing the paper, so that it terminates approximately only at the corners of the
box, and if removed therefrom by any considerable space, the joint is practically
as noticeable and objectionable as though it occurred in the middle of a side.
I will here state the operation of the devices just above described, for the sake
of convenience. The shaft 8 being positively driven by the gearing shown, the
part 10 makes continuous revolution with it, and by reason of the engagement of
the pin 14 with the hole 16 the two parts necessarily travel together. When
however, the extremity 23 of the spring 15 comes in contact with the deflecting
surface 22 on the frame of the machine, the spring 15 is withdrawn carrying the
pin 14 with it, and immediately thereafter, the laterally projecting end of the pin 18
strikes the top 20, so that the end of the pin 14, which has been sufficiently
withdrawn, traverses the slot 17 in the part 11, as indicated by dotted lines in
Fig. 9. During the same time, the pin 18 traverses the slot 19 in the part 10, and

page_text: it is at this time that the cutting blades operate and sever the covering papers, as
will be explained, and, in order to bring the parts back again to their normal
position, a spring 24 is located in an annular recess 25 in the part 11, which abuts
at one end against a stud or pin 26 in the part 11, and against another pin 27ª in
the part 10.
The instrumentalities which actuate the cutters are as follows: 27 is a thumb or
stud like projection extending radially from the periphery of the part 10, which in
its revolution comes in contact with a roller 28 which is set on the end of an arm 29
which is keyed to a shaft 30, which carries by a suitable arm 31, a connecting
rod 32, which engages by a thumb nut, or other suitable device 33, with the
movable blade 34 of the shears, which is pivoted at a centre 35. The fixed blade
of the shears 36 is set low down, so as to be as close to the box as possible. The
box forin is fastened by means of a set nut 37 and milled thumb nut 38 upon a
threaded spindle 39, which is attached to the part 11. A spring 40, one end of
which is made fast to a suitable support such as an arm 41, which may be attached
to the bracket 3, and the other end fastened to a lever arm 42 which is fast by
means of a hub 43 upon the shaft 30 of the knives serves to operate said shaft and
knife. 44 is a slideway upon which a slide 45, which carries the cutters, is
adjusted in any desired position by means of a set screw 46. The cutting blades
are adapted to any desired elevation by being provided with a hub 47 aud spider
spring for friction arms 48, which is set up or loosened by set nuts 49.
screw 50 passing through the hub, engages with a vertically arranged rod 51, upon
which the cutting devices slide. 52 is another vertical rod for supporting the
paper guiding devices, already described. It will be seen that the construction of
the parts above described, and as shown in Figs. 7, 8, 9 and 10 is much more
compact and simple than that shown in the other figures, and, also that by reason
of supporting all of the parts from the single arm 3, there is nothing at the outer
end which interferes with the cutters being brought up quite close to the box form.
Consequently I can so adjust my machine as to sever the paper practically at the
corner of a box not larger than one and one half inches at the largest dimension.
This is a great desideratum; and, in addition to this feature, the other advantages
before referred to, obtain.
A set
The operation of the apparatus will be readily understood from the foregoing
description, since such machinery in its general features is now well known; that
is to say, the reel or reels of paper are placed upon the shaft R at the left hand of
the machine, the flange S¹ being removed for the purpose, and will be especially
observed that, owing to the shaft R being supported at one end only i.e. by the
arm O, that the application of the coils of paper can be more easily and speedily
made than in machines as heretofore constructed because all that is necessary is to
remove the flange SI and, indeed, it is not absolutely essential to use such flange.
If two or more strips of paper are to be applied, I prefer to employ a dividing disc
or flange between the several coils or reels of the paper. This is not essential,
however the paper passes from the reel or reels under the bar U; which is
adjusted vertically, as the necessities of the work require; thence over the glue
roll I which applies the paste to one side only of the paper, the glue roll being
caused to revolve by the pull of the paper over and upon it; then in contact with
the scraper; thence through the guides b, b, whereby the paper is brought into
proper alignment; thence through the guiding and superposing fingers m, m', m³, m³
whereby the two papers are caused to be overlapped one upon the other; thence
over the bar p upon which the several papers are united, becoming one by reason
of the adhesive material upon their under sides; thence between the flexible
supporting and guiding fingers, thence through the shears or cutter, and so on
to the revoluble or rotary box form, and the stringing of the paper through the
machine is facilitated because in every case where it engages with guide rods or
the like, they are supported at one end only, leaving the other end open, so to
speak, so that the paper or papers is simply passed around such unsupported end,
and thus greatly facilitating the operation of putting the papers on the machine.

page_text: The apparatus, if driven by steam, is belted in any suitable manner, by reason of
the belt wheel r which actuates the parts in a manner well known. If power be.
not employed, the machine, with proper modifications, may be operated by hand by
manually turning the box upon its rotating form, in a manner well understood.
1 call particular attention to the fact that this machine is peculiarly simple and
durable in construction; that all its parts are adjustable relative to one another,
and are all mounted upon the longitudinal rod E, so that whatever the extension or
retraction of the machine may be, in other words, whether extended to its utmost.
length or shortened up to its shortest dimension, all of the parts maintain their-
proper longitudinal alignment, which is a matter of great consequence, in apparatus:
of this character, and that the machine may be extended or closed up either as.
a whole, or at one end or the other, as required, by simply loosening the set screws.
and pulling or shifting the parts along upon the central rod E and rod u to the.
desired position, and that the cther advantages already referred to are likewise.
realized. 1, furthermore, especially refer to an advantageous feature in this machine,.
which has never, so far as I understand, been heretofore embodied; that
to say.
after the machine has once been started, it will invariably complete a revolution of
the box form, irrespective of any act on the part of the operator; consequently the
machine compels the operator to diligently attend to his work, because the paper
will be wrapped about the box by the machine, and it must be properly
manipulated at that time, and, furthermore, the paper is under the same tension
from start to finish, no slack paper at the corners, which results in bubbles,.
wrinkles and laps, is possible, which is incidental to the use of all forms of prior
machines, and furthermore, the construction and timing of the parts is such that as
the revolution of the box approaches its termination, the momentary delay above-
referred to in connection with the box form clutch takes place, during which the.
paper is severed, and, thereafter, the machine still further operates for a brief
period, revolving the box form somewhat further, so that the lap end of the severed.
paper can be rubbed down properly before the driving clutch operates to definitely
stop the mechanism.
I do not limit myself to the details of construction described and shown, because.
it will be evident to those who are familiar with this art, that alterations may be.
made therein, without departing from the essence of the invention.
