page_text: mechanism comprising the mandrel B, or, strictly speaking, as the machine is
constructed, the two mandrels which are in axial alignment and arranged and
operated for intermittent end wise separation..
Of the two feed rolls, 20, 22, one 22, is above and the other 20, below the level
of the infeed of the paper, while the vertically movable gate-gage D, is next to
the rear of these rollers and the upper feed roll is intermittently vertically
movable so that when the gate-gage is in its lower position, the sheet of paper may
be freely slid by hand, so as to "
square it against the gate while the roller is
elevated. Then as the gate is raised to permit the paper to be moved rear-
wardly, the upper feed roller is brought down to contact with its fellow to ensure
such feed.
The upper feed roll 22, has its gudgeons set in the vertically elongated journal
socket seen at 27 in Figures 4 and 5, and its properly timed intermittent
movement is effected by means as follows:-
The rotary cam-carrying counter-shaft E, which is to the rear of the main-
shaft C, bas the cam 30, thereon, against which impinges one lever arm 32, of
a rock-shaft, 31, while to the other lever arm 33, of such rock-shaft, is connected
the lower end of the thrust-rod 34, the upper end of which has a lifting
engagement with the one end gudgeon of the roller.
This cam-actuated mechanism is duplicated for the manifest action at each end
of the roll.
The lower feed-roll is grooved circumferentially, as seen at 35, so that the
horizontal supporting and guide-rods 36, may have their positions properly below
the plane of the contact between the feed-rolls. The gate-gage D, is apertured at
its lower edge, as seen at 37, most especially in Figure 6, so that its vertical move-
ments will not be interfered with by said rods which extend rearwardly beyond the
gate-gage.
The gate-gage, which moves in slide-ways 38, therefor at its ends, has its vertical
movements intermittently and in proper time imparted thereto by means, as
follows:-
The horizontal rock-shaft 40, has duplicated radial arms 42, which are linked to
the end portions of the gate: to another radial arm 43, of the rock-shaft is attached
one end of the connecting rod 44, which has its other end secured to the lever 45,
which has the operative engagement with the cam 46.
The support and guide-rods 36, for the rearwardly fed sheet of paper are
supported on the horizontal bar 47; and above these rods 36, 36, and between the
gate and the paste-rolls, are a second shorter series of rods 48, 48, which are
supported by the bar 49.
These rods serve to prevent the paper from unduly curling up or wrinkling.
Of the two paste-rolls 23, 24, the lower one rotates with its lower portion in the
paste-box 50, while the upper paste-roll has its end gudgeons jourualed in boxes 52,
which by the spring 53, are downwardly pressed.
A lever-arm 54, extended from rock-shaft 55, projects for a lifting engagement
under each upper paste-roll-journal; said rock-shaft derives its rocking movement
periodically by reason of the connection with its lever-arm 56, of the thrust-
rod 57, which is subject to the action of the cam 58, which is most clearly
seen in Figure 4, and which has its prominent portion of but slight extent
circumferentially so as to only lift the upper paste-roll for a short period of
time.
The reason for the lifting of the upper paste-roll which occurs just before the
forward edge of the sheet of paper or tube-blank comes to the line of the con-
tacting surfaces of the two rolls, is to avoid the undue accumulation of paste at the
"throat" of the rolls, whereby the front edge portion of the paper would receive
an excessive amount of the adhesive.
Furthermore, the avoidance of the excess of paste at the throat permits the edge
of the paper, which is usually of reduced thickness, to readily pass between the
paste-rolls.

page_text: Between the paste-rolls and the mandrel are the upper and lower sets of runner
or support and guide-rods 60, 62, ranging horizontally fore and aft, just below and
above the level of the feed of the paper, they being supported on the transverse
bars, 63, 64. And also between the paste-rolls and the mandrel is the series of
feed disks or rollers 65, all on the common shaft which is suitably rotated.
The rotary winding mandrel is formed separable, that is in two lengths B, B,
arranged in a common line with their ends in, or about in, abutment, and adapted
to be moved axially away from each other, each drawing out from the roll which
had been wound thereon..
214
The mandrel sections B, B, are mounted to rotate and also to slide through
bearing supports of the frame of the machine, seen at 66 and 67. One of the
bearing supports 67, for each mandrel section, has its journal opening larger than
the mandrel for the accommodation of the sleeve, 68, which surrounds such section,
so that the sleeve may rotate with the section B, said rotation being imparted
thereto by the engagement of the gear-wheel 69, on the sleeve 68 with other
gearing, as seen in the end clevations, although of course the sleeves surrounding
the inandrels may derive their continuous rotary movements in any other manner.
Each sleeve 68, has the internal feather 70, which engages in the spline-
groove 72, of the mandrel section B, so that while the section will be continuously
rotated by the rotary sleeve 68, it may have its end wise movements independently
of, and without impediment by, such sleeve.
The means here shown for imparting the end wise movement to the mandrel
sections to periodically draw them end wise apart and then return them to end wise
contact, or proximity, consists, as to each mandrel, of parts and arrangements as
follows:-
-
The screw-threaded outer extremity of the mandrel-section is passed loosely
through the opening 73, (Figure 7) in the upstanding member 74, of a rack-bar 75,
which has horizontal slides 76 working in slide ways, in the machine-frame, below
and parallel with the mandrel.
The nuts 77, 77, screw on to the said threaded portion of the mandrel at each
side of the upstanding member 74, of the rack-bar, so that, while the mandrel is
Free to rotate independently of the member 74, when the rack-bar moves endwise,
the mandrel must. correspondingly move.
The lever 78, corresponding to each mandrel, has a lower portion thereof
pivoted on the framing at 79, and has its upper extremity formed into the sector-
gear 80, which engages the rack-bar.
1
Both of these sector-provided levers receive their simultaneous movements
thus, reference being particularly had to Figure 2 :
The bar or rod 82, has one end secured to one of the levers 78, and receives
reciprocatory movement by having the roller-stud 83, thereof engaging within the
cam-slot 84, of the disk, or wheel 85, which receives its continuous rotary motion
in any ordinary manner.
The one sector-lever, 78, has below its pivot the extension arm, 86, with which
is attached the connecting rod 87, which at its other end has a connection with the
other sector-lever above the pivot thereof. Hence the two sector-levers simul-
taneously have their swinging movements towards and from each other.
Just to the rear; and with its axis a little below the sectional mandrel B, B, is a
roll G, having longitudinal outstanding flexible blades 90, 90, which may be of
rubber.
.
This bladed roll is journaled in slide-blocks 92, 92, (Figure 2) movable in
ways of the frame, so that the roll may intermittently be brought to lap or
impinge against the mandrel or, rather, against the forward edge of the paper,
just as it reaches the mandrel, for the purpose of causing the forward edge
of the surface-pasted paper to immediately take its winding engagement with the
mandrel.
The movements of the carrier slides for this bladed roll are imparted by the
attachment to each end of the arbor of the bladed roll of a connecting-rod 93, each
..... 14'

page_text: of which is also connected to an arm 94, of rock-shaft 95, to another arm 96,. of
which rock-shaft is connected the thrust-rod 97, which derives its reciprocatory
movements in the proper time by the cam 98.
The bladed roll G, is so speeded that the blades thereof have their revoluble
movements faster than the circumferential motion of the mandrel:-hence the
paper will be wiped with absolute certainty against the mandrel.
As here shown as a means for effecting the relative speeding of the wiper roll
and the mandrel, specified, the counter-shaft C Fig. 4, is driven by belt and pulley
from the main-shaft, C.
Now the mandrel has imparted thereto its given rotation at the proper rapidity
by the pulley B, on the counter-shaft C3, the belt B', passing around said pulley B³,
and around the pulley B₁, on the shaft B5, which has thereon the gear-wheel B,
that meshes into the pinion B', on the mandrel.
The bladed roll or wiper G, has on its end the small pulley G': and the counter-
shaft C, has thereon the much larger pulley G³, around both of which pass the
driving-band G. Therefore it will be plain that as the diameter of the pulley G³,
is so much greater than that of the one G³, and so proportionately greater than
the diameter of gear-wheel B', relative to pinion B7, on the mandrel, that the
greater rapidity of speeding of the wiper is acquired. This result may of course
be ensured by divers other mechanical means which would not be matters of
invention, but of ordinary mechanical expedients.
About simultaneously with the coaction with the mandrel of the bladed roll G,
the presser and scraper-bar or blade 100, is moved to contact against the convolu-
tions of the paper as they are being wound to ensure firmness and closeness of
winding, and also the removal of excessive quantities of paste.
This presser and scraper blade is carried by a bar 102, which is arranged to
have sliding movements transversely of its length diagonally rearwardly and
upwardly above and relative to the paste-box 50.
103 represents the slide-ways for the bar 100, and the bar derives its movements
of presentation against, and withdrawal from, the mandrel by reason of the link-
connection therewith of the arm 104, of the rock-shaft 105, which is operated by
the thrust-rod 106, which latter receives its impulse from the cam 107.
By reason of the position and inclination of the said presser and scraper-
bar 100, relative to the paste-box any excess of paste of which the paper-tube is
relieved runs back into the paste-box.
The operation and effect of the machine is rendered manifest in and by the
descriptions and explanations hereinabove given, and are rendered still clearer by
reason of the drawings on Sheet 7, in which
Figure 9 shows, while one paper blank is being wound on the mandrel with the
blade-roll G, and the scraper in operative proximity thereto, the paste-rolls 23, 24,
are running in peripheral contact whereby the upper roller also receives its coating
of paste from the lower roll, the gate-gage is in its lower position so that the next
paper blank may be squared, and at this time the upper feed-roll 22, is lifted so
that the paper may be properly squared against the gate.
Figure 10 shows the relative positions of the parts when the sections of the
mandrel are separated to ensure the discharge of the completed tube,-the bladed-
roll and scraper 100, being carried out of their positions for contact with the
mandrel, and the gate-gage is raised, the upper feed-roll 22, is lowered to feed
the paper-blank to and between the gum rolls, the upper one of which, just as the
forward edge of the blank comes thereunder, is also raised, such upper gum roll
descending, however, immediately the edge of the blank has fairly come under its
lower central portion so that the extreme edge of such blank receives paste as well
as all the rest of the superficial area of both sides thereof.
Figure 11 shows the substitution for the bladed upper roll G, of a brush-roll, G,
which may perform the same function.
In practice, the distance between the paste-rolls and winding mandrel is some-
what less than the width of the blank from which the tube is to be formed.

page_text: Therefore the paper which bas been squarely fed between the paste-rolls has a
portion thereof still between such rolls at and somewhat after the instant that'
the forward edge of the paper is wiped to its engagement on the winding
mandrel.
It will be seen, on reference to Figure 7, that one of the mandrel sections B,
has the passage 71, from its inner end leading longitudinally therethrough for a
distance greater than the length of the portion of the mandrel which is to be
surrounded by the tube and this passage has communication with the exterior of
the mandrel as by leading to the spline-groove 72. Therefore, as the mandrels
separate for their withdrawal from the completed tube no vacuum will be produced.
within the tube to collapse it, or to cause it to unduly adhere upon the mandrel.
·
It will be here mentioned that in the event of the paper tube having a tendency
to remain on the one mandrel section while the other is withdrawn therefrom, it
will, by having its end brought against the bearing support 66, be prevented from
moving end wise with the first mandrel section, so that the latter may also be drawn.
