Improvements in Mechanism for the Manufacture of Packing for
Bottles and analogous Articles.
1, EDGAR JAMES STUART, residing at Number 720, Eric Street, in the City and
County of Sheboygan, State of Wisconsin, United States of America, 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 following
statement:-
My invention relates to the manufacture of packing tubes, pads, and the like and
it consists in certain mechanism therefor, which will be fully described hereinafter.
In the drawings,
Figure 1 is a side view, partly in section, of my invention.
Figure 2 is a plan view partly broken away and in section.
Figure 3 is a vertical longitudinal section through the machine.
Figure 4 is a side view of the delivery end of the machine with the rollers at that
end in dotted lines.
Figure 5 is a section on line 5-5, Figure 3.
Figure 6, a section on line 6-6, Figure 3, and
Figures 7, 8, 9, 10, and 11, sections on lines 7-7, 8-8, 9-9, 10-10, and 11-11
of the same figure, and
Figure 12 is a detail.
Figures 13 to 16, inclusive, are end views showing different stages in the operation
of the machine.
A A are the side pieces of a frame, which is supported by uprights B, that form a
solid foundation. These sides are connected by suitable bottom strips C, and in them
are formed bearings for the various rollers that form part of the machine.
A shelf a
b
extends from one side to the other at the receiving end of the machine, and around
this is an apron a', which runs on rollers 6 c, and the shaft of the latter roller carries
on one end a bevel-wheel d, that meshes with a like wheel fon a shaft f, that is
geared at g to the main driving-shaft D of the machine. Just forward of shelf a, but
on a lower plane, is another shelf h, which is guarded by a roller h', which receives a
strip of paper from a roll 2 and conveys it onto the shelf ; and just forward of
shelf h, but journalled on a higher and lower plane, respectively, and slightly separated
from each other, are two feed-rollers E and F. The lower roller is to take the paper
from the shelf and the upper roller to take a strip of paper from an upper roll G.
The feed-roller E is driven by the shaft D through bevel-gearing k, and in turn drives
the roller F through cog-gearing m.
An open funnel-shaped former H is suspended between the sides A in such position
that its mouth almost touches the rollers E and F. The mouth of the former H is
trough-shaped, and from this point the edges gradually approach each other until
they meet and form a tapered tube at the delivery end.
A mandrel H, which is substantially oval in cross-section and tapers to a flat
point, is suspended in the former from bars m² m², so as not to touch the sides of
the former, and the flattened end of this mandrel projects from the former between

page_text: the rising peripheries of two delivery-rollers II', which are driven by shaft D, just
as rollers E and F are driven.
In front of the rollers I l' are journalled two other and smaller rollers jj. The
bearings of the shaft of roller j¹ are fixed, and on one end this shaft is connected by
pinions o o¹ and p p with the pinion q' on the shaft of the roller 1', which pinion, by
meshing with a pinion 7 on roller I, serves to drive it also; but the shaft of roller j
has its bearings in a gate s, from which is suspended a weight t by a cord
which
weight causes the roller to compress the stock as it passes between it and roller 7'.
A crank-arm L on the forward end of a shaft N carries a knife M, and the path
of this knife is shielded by a guard M, that is fixed to the delivery end of the
machine, and an opening m² in this guard permits the completed stock to pass out
as it is cut off by the knife in its revolution.
The shaft N has its bearings in two of the forward uprights B, and on its inner
end carries a disk n, the face of which is eccentrically connected with the face of
another disk n' on a shaft P by a link P¹, and this shaft P, which has its bearings
in two of the inner uprights B B, is connected by cog-wheels R R with the shaft B,
by which it is revolved. These wheels are of such relative diameter as to properly
time the action of the knife to cause it to sever the stock at the proper intervals,
and thus produce the desired length of stock. The shaft D is driven by a belt and
a pulley D, acting through its shaft and bevel gear-wheels D2 D3.
The shaft of the lower paper-roll is journaled in brackets ³ on two opposite
uprights B B, and that of the roll G in standards G', that project up above the frame,
and the tension of the roll is regulated by a spring G2 and weight G³.
T is a glue-pot that has three separate gravity discharging-sponts T T T2, the
spouts TT for distributing glue to one side of the lower strip of paper, and T for
distributing it to the other edge and opposing side of the upper strip.
U is another glue-pot that furnishes the glue for sticking the edges of the
composite packing together.
Owing to the manner in which the upper and lower strips of fabric are united
by my device, it is necessary that I should have a glue-receptacle provided with
independent gravity discharging-spouts, arranged substantially as above described.
My packing consists of two layers of paper or other fibrous material inclosing
between them excelsior or a like substance of resilient nature; but for the purposes
of description I will only refer hereinafter to paper and excelsior as composing my
packing. The lower strip of paper is about as wide as the rollers E and F are
long, and the upper strip is not quite so wide. The excelsior is fed to the lower
strip by apron a', and as the lower strip is carried forward by its roller ¹ it takes the
excelsior under spouts which drop glue onto it, and thence under the upper strip,
and the two strips are pressed together by the rollers E F. The upper strip is
caused to adhere to the excelsior ate and to the lower strip at w, and then the two
strips pass into the former and are bent first into the shape shown in Fig. 15, and
finally, as they pass out of the former, the edges of the lower strip receive glue
from spout U¹, and then the rollers II press them together and form a tube of
them which is cut into suitable lengths as it passes from rollers by the knife.
When simple sheets of batting are to be made, the final gluing is omitted, and
after the stock is cut off it may be used for padding carpets, &c.; or, in addition
to the omission of the last glue-pot, the inrolling of the upper portion of the former
may be dispensed with, leaving it trough-shaped from end to end. It will be observed
that the excelsior is only glued to the upper fabric, and that the two fabrics are only
glued together on one edge. This is done as the stock passes between rollers E
and. F, and then when tubes are to be made of the stock the former and mandrel
bring the edges of the lower or widest strip together so that they may be joined
by the glue from spout U₁. The excelsior should be fed to the longitudinal
centre of the lower strip of fabric, and therefore I secure a wing X to each side
piece A at the receiving end of the machine by means of lugs y y¹. These wings
are of elastic material, and the lugs y' that project from them are slotted and are
adjustably secured to their respective side pieces by set-bolts y³, so that the wings

page_text: may be inclined toward each other at that end to properly guide the excelsior onto
the lower fabric.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
1. The combination, with a suitable frame, of lower feed-rollers for carrying a strip
of fabric from a roller thereof, an upper feed-roller for conveying a strip of fabric
from an elevated roll, a gravity discharging glue-receptacle having separate spouts
feeding independently on one side of the lower strip and on the opposite side of the
other strip of fabric, and an apron for feeding a filling to the lower strip of paper.
2. The combination, with the fabric and excelsior feeding-mechanism, of suitably-
arranged glue-spouts, a former arranged to receive the stock from the feed-rollers, a
mandrel suspended in and projecting from the forward end of the former, compressing
and feed rollers for taking the stock from the mandrel, and a revolving knife and
mechanism for operating the parts.
3. The combination with the feeding mechanism for the strips of fabric and the
excelsior feeding-apron and wings for guiding the excelsior therefrom to the centre
of the lower strip of fabric, of glue-spouts and rollers for compressing the excelsior
and fabric together, a tapered former for receiving the stock so formed, a mandrel
suspended in and projecting from said former, rollers for taking the stock from the
mandrel, and operating mechanism.
4. The combination, with the feeding mechanism for the strips of fabric and
mechanism for feeding the filling between the strips of fabric, of a tapered scroll-
shaped former, a tapered mandrel suspended in the former, a glue-spout arranged to
project between the edges of the sheets of the fabric as they leave the former, and
rollers for compressing the edges together.
5. The combination with an excelsior delivery apron and adjustable guides therefor,
of rollers for feeding a strip of paper above and below the excelsior, a former arranged
to receive the stock thus combined, a mandrel suspended in the former, rollers for
drawing the stock from the former and glue spouts for supplying glue to seal the
parts of the stock together.
