I, MATHIAS SCHAFFHAUSER, of Cernay, in the Department of the Upper
Rhine, in the Empire of France, Manufacturer, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE MACHINERY FOR MAKING PAPER
TUBES USED IN SPINNING MANUFACTORIES," to be as follows:-
_
The object of my improved machinery is to make the paper tubes used in*
cotton, wool, silk, and other spinning factories. The machines of this description
hitherto used do not make more than from forty to sixty tubes per spindle
per minute, whereas my improved machinery makes from one hundred to one-
hundred and ten, using relatively less power.
My improvements are illustrated in the Sheet of Drawings hereunto annexed,
and forming part of this my Provisional Specification, and to which reference
is made in the following description.
The strip of paper from which the tubes are to be made is taken between
the cast-iron rollers Y and Y', which bring it on the small cast-iron table T,
serving to receive the paper and pass it to the spindle. As soon as the requisite
quantity of paper is on the table T, the shears S, moved by the lever L, are
set in motion and cut from the strip the quantity of paper required to make a
tube. At the same moment the shaft i, at the end of which is the mould of
the tube which it is desired to obtain, being pushed by the excentic C'advances
in the direction of its length and seizes the paper, then the mould or spindle Z
begins to rotate quickly, in which movement it very exactly rolls the paper,'

which is obliged to pass between the spindle and the roller K, which turns in
the same direction. On this roller K is fixed a small leathern strap which
presses the paper against the spindle, the paper being rolled round the mould
and having pasted itself together. (I would here observe that before delivering
the strip of paper to the machine it is soaked by any of the well known and
simple means with paste made from starch); the mould retires briskly, because
the action of the excentric C ceases at the same instant and permits the spring
Qto sharply draw back the shaft i in the direction of its length.
retrogade motion the paper tube is left behind, because at the end of the
table T is fixed a species of clutch box x, which exactly admits the spindle <,
which in retiring is obliged to pass through it, whereas the paper tube remains
behind abandoned to itself, falls by an opening beneath in foundation plate
into a receptacle. There remains to explain, first, by what means the rollers
Y and Y¹ are set in motion to bring the paper on to the table T, and to bring
it only at the proper moment. The machine receives its motion from the two
driving pullies M, which communicate motion to the shaft a and a', on which
they are fixed, the conical cog D gearing into the cog D', transmits the same
speed to the shaft d, d', which by means of two cogs H and H' communicate
a rotary motion to the roller Y, which naturally turns in a direction the
reverse of that of the shaft a, a', but makes the same number of revolutions
per minute, inasmuch as the cogs D, D', H and H', have the same number of
teeth. Above the roller Y is a roller Y¹, of equal diameter, fixed on a small
shaft, from the two ends of which hang the iron wires of balance weights,
which is the reason why the rollers Y and Y¹ do not touch, but on the roller Y
is fixed extending a certain calculated length a piece of calf skin, which rises
level with the outer circumference of the roller Y¹, when the side of the
leather comes to pass through the two rollers by reason of this prominence
the rollers touch, and by reason of the balance weights p and p¹ the friction
between them may be increased or lessened at will. Secondly, by what means.
the lever L, which causes the shears to act, is set in motion. The lever L
works round the pin t, and at each turn of the shaft a, a', the steel piece q
fixed on the helicoidal wheel A on one side causes the lever to descend, and
on the other causing it to rise, thus works the shears S. Thirdly, what is
the construction of the eccentric C; which pushes forward the spindle. This
eccentric (which is shewn detached, drawn half the usual size) is fixed by a
simple screw against the wheel A. It is as may be seen nothing else than part
of a circular disc ending in two axis of a circle directed towards the centre.
The length of the outer circumference of this eccentric is so placed and
calculated on the roller A, that so long as the spindle must work to roll the

page_text: tube the disc does not cease to act, and thus prevents the spring Q from
retiring the shaft i, and that as soon as the tube is made, the disc ceasing to
act leaves the spring free to draw back the shaft i in the direction of its length.
Fourthly, what is the construction of the spindle, and how does it seize the
paper. The spindle is made of a single sheet of steel bent on itself, and to
which is given the shape of the tube which is to be made, only the two ends
of the spindle are not united, a groove being left in its entire length large
enough to admit the sheet of paper, and at the end of the mould the groove
is enlarged like the arc of a circle in order that the sheet of paper may
more surely engage itself. Fifthly, how does the spindle receive its rotary
motion after having seized the paper, and why does this movement cease the
instant the tube is formed? The basis of this movement is principally
the couple of toothed wheels A and B (shewn detached, drawn half the usual
size), which are as may be seen helicoidal. The toothed wheel A is, as may be
seen, only toothed over a certain calculated distance, on the rest of its crown
extends a ridge, its number of teeth is fourteen; the toothed wheel B on the
contrary is composed of fifteen teeth, the two last of which are sunk further;
between the two latter teeth is made a groove parallel to the shaft b, b', this
groove is intended to receive the ridge of the wheel A. The action of these two
wheels is as follows:-Supposing that the ridge of the wheel A is engaged in
the groove of the wheel B, this wheel B naturally remains unmoved, but as
soon as the ridge or fillet ceases and the teeth of the wheel A attack those
of the wheel B, the shaft b, b', receives a rotary motion, which lasts as long as
the teeth of A are engaged in those of B, but as soon as the teeth of the
wheel A are succeeded by the ridge, which always enters exactly into the groove
of the wheel B, the shaft b, b', stops again; therefore when the shaft b, b',
rotates, the wheel E keyed on this shaft turns the shaft i. The machine
naturally requires to be regulated so that the spindle turns at the moment it
should roll the paper, and ceases its rotary motion at the moment it retires,
drawn back by the spring Q.
