Germany, Engineer.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
ained in and by the following statement:-
The present invention relates to improvements in mercerising or like machines
n which the hanks yarns etc. to be treated are arranged on pairs of cylinders of
which one serves as the stretching or tension cylinder, the cylinders being succes-
sively given a rotary movement around their axis, and, by rotatory movement of
the whole system of cylinders, also around the main or central shaft of the
machine.
The improvements comprise:-
-
1st. A curve guide device in sections for the purpose of producing in the hanks
a tension and release as required according to the phases of the operation.
2nd. A friction device for the purpose of producing a periodical movement of
rotation and a periodical stoppage of the whole system of cylinders provided
with the hanks to be mercerised or treated.
3rd. A device by means of which the vessel containing the mercerising or other
liquid can be moved.
A machine provided with these improvements is represented in the accom-
panying drawing by way of example:
Figure 1 is an elevation of the machine, partly in section, with the curve-guide
represented schematically.
Figure 2 represents the curve-guide device, and
Figures 3 and 4 represent respectively a front and side view of the friction
device.
In Figure 1, g represents the standards of the machine serving to support the
shaft won which is fixed a wheel d provided with the pairs of cylinders a³, b³,

These pairs of cylinders are intended to carry the hanks etc. to be mercerised

or treated and consist of tension cylinders 61, 12

The chain T is actuated by a chain wheel T¹ keyed on a shaft to which

rotatory movement is imparted in any suitable manner.
counterweight at its outer end is knotted at 3 and carries a toothed pinion t² at its
other end engaging the chain T and thus serves to impart to the chain T any
required degree of tension, by adjusting the counterweight at a suitable distance
from the pivot 3 of the said lever T2.
The different movements which it is required to impart to the cylinders

page_text: 6 for the purpose of obtaining the required tension, extra tension, and
release of the hanks are produced by arranging the cylinders at the end of
cranks h, on the shafts of which are arranged levers provided at their free
end with rollers & which roll along the curve-guide ir, secured to the frame g
of the machine and represented schematically in Figure 1 and in detail in
Figure 2.
This curve-guide is formed of three independent parts and which are
respectively provided with inwardly extending racks op gearing with a toothed
wheel common to all, and serving for their adjustment.

A fourth rack bar m also engages with the said-toothed wheel and at its outer
ends in a nose n² which enters each other, in consequence of their moving away
from the centre w owing to the action of the wheel n.
The section of the curve-guide consists of two tracks and t and is provided
with two tappets/ (actuated by hand and maintained in the required position
by any suitable means) which according to whether they are raised or lowered,
cause the rollers k of the tension cylinders to pass either along the circular outside
grooves or along the inner groove t; the latter being nearer to the shaft w and so
arranged that when the hanks are intended to pass, for instance twice through the
mercerising liquid the tappets are only raised at the second revolution for the
purpose of sufficiently slackening the system to allow of the hanks being removed
during this second revolution. It will be easy to understand that when the
toothed wheel turns in the direction indicated by the arrow (Figure 2) for
example, the segments i j and will be forced away from the centre of the shaft w
involving in that movement also the moving apart of the pairs of cylinders a¹ b

the hanks.

The cylinders a¹ a² a are put in motion by means of the chain T which
gears with the toothed wheels keyed on the axles of the said cylinders. The
cylinders b².

and transmitting the movement from the cylinders a¹ a²

ders 61 12
The friction device which is intended to produce the periodical rotation of the
whole system of cylinders as well as the periodical stoppage of the system, is
represented in Figure 1 and also in detail, in Figures 3 and 4. This device consists
of a grooved pulley keyed on the main shaft of the machine. In contact
with this pulley is a correspondingly shaped roller c, the shaft of which is
provided with a chain wheel. The roller e and wheel 2 are arranged at the
end of a lever h² which is connected by a rod e with a horizontal lever attached
at one end to a shaft or stud, to which is connected a vertical lever carrying
at its lower end a roller f adapted to roll along the periphery of a cam k³, provided
with a recessed part as shown in Figure 4.
The rotation of the cylinders a¹, 61, a² ².
on their axes is affected
by means of an endless chain T, actuating the wheels S, while the rotation of the
whole cylinder system, which alternates with that of the cylinders is produced
by a chain which actuates continuously the wheel on the axle of the roller e,
which actuates by friction the grooved pulley, whenever the two latter are in
contact with each other.
The friction between e and gas well as the time during which such action is
intended to be effective are determined by the cam 3. As long as the roller f
runs along the circular outer periphery of the said cam the roller e is held out of
engagement by the intermediate parts b, a ch² and consequently produces no
effect whatever on the pulley g³, which therefore, remains stationary together with
the shaft w and the whole system of cylinders.
During this time the cylinders a¹ a² a alone are actuated, since it requires
less force to turn these cylinders round their axles than to turn the whole system
of cylinders round their central axis w: therefore, no rotation of the cylinders
takes place round the latter. But as soon as the roller f arrives at the receding

page_text: part of the periphery of the cam, the weight on the free end of the lever a acts
to press the roller e against the pulley thereby transmitting its movement to
the latter which then involves in its movement the snaft w and consequently the
whole system of the cylinders until the rollers f pass again on to the outer
periphery of the cam i.e., in the case of the machine illustrated during one-sixth
of a revolution.
When this roller e (Figures 3 and 4) is not engaged with the pulley g², the
wheel d¹ remains stationary, because it requires more force to actuate it than to
actuate the pairs of cylinders a¹ b etc. Owing to this the cylinuers receive a
rotatory movement through the chain T, and the toothed wheels S, while at the
same time remaining in the same position relatively to the centre w of the
machine.
When, on the contrary the roller e is brought in contact with the pulley g² the
wheel d is caused to rotate during one sixth of a revolution the rotation taking
place in the direction of movement of the chain T. It follows therefore that,
during this rotation, the toothed wheels S of the cylinders a¹ etc., receive no rotary
movement from the chain T, although rotating round the centre w with the
latter, and consequently the cylinders a betc. remain stationary on their axes.
When the wheel is stopped again after one sixth of a revolution the cylinders
re-commence turning on their axes.
The arrangement whereby the lower vessel X containing the mercerising or
other liquid is rendered movable, is represented in Figure 1, and consists of the
arrangement of the vessel X on four or other numbers of uprights connected
to horizontal levers f² provided with counter-weights corresponding to the weight
of the vessel X and the liquid contained in it.
During the rotation of the whole system of cylinders the cylinders a¹, b',
a², be
a, b successively press against the edge and thereby force the
vessel to descend so as to allow them to pass by. When the system of cylinders
stops, after having passed through one-sixth of a revolution, the vessel actuated
by the counterweights of the levers fascends until it meets the cylinders. In
this manner the hanks on the cylinders are well dipped into the liquid; and
they will be found to be impregnated much more rapidly than is possible with
other mercerising machines in which ine hanks come in contact with the lye
during a very short period.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
1. In a mercerising or like machine, a fixed curve-guide for moving the tension
cylinders nearer to, or farther from the fixed cylinders, comprising three adjust-
able sections of which one is provided with two tracks while the others offer only
one track each, these adjustable sections being each provided with a rack bar or
equivalent gearing with a toothed adjusting wheel for the purpose of fixing the
distance of the corresponding sections from the centre according to requirements,
substantially as described.
2. A friction device for the purpose of periodically rotating the whole system
of cylinders comprising a pulley keyed on the main shaft a rotating roller acting
by friction against said pulley whenever it is caused to come in contact with the
said pulley by means of any suitable device actuated by a cam so constructed
that one part of the said cam will produce the displacement of the roller so as
not to affect the pulley which then remains stationary together with its shaft,
while the other part of the cam is so formed that it causes the roller to come in
contact with the pulley thereby producing, through friction, the rotation of the
latter, substantially as described."
3. Means for rendering movable the vessel containing the mercerising or other
liquid characterised by the arrangement of the vessel on four or any suitable
number of uprights connected with horizontal levers provided with counter-

page_text: weights corresponding to the weight of the vessel and its contents and so arranged
that the said vessel can be pressed down by the cylinders at the moment of their
passing, substantially as described.
