Improvements in and relating to Work Rollers for Lace Machines.
FRANK NEWTON HOBSON 11 Boech Avenue Sherwood Rise Nottingham
Machine Builder do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in and relating to work rollers of lace
machines, and has for its object the provision of means for enabling the work roller
to be brought to the front of the machine, and means for enabling the roller to be
rotated for removing the work without pulling the latter.
At the present time the work is taken up by a porcupine or other similar roller
and is wound upon a work roller which is driven by contact with the porcupine
roller. The work roller is fitted to slide vertically in guides and is raised and
lowered by levers, and the work has to be pulled off by hand at an angle to miss
the front part of the machine.
Now according to this invention the work roller guides are shaped to allow of
the roller being moved vertically and horizontally, and the levers are so shaped
and centred that they lift the roller to the top of the vertical guides and then
move it forward in the horizontal guides. The end of the work roller is fitted
with a toothed wheel which gears into a toothed wheel, carried by a fixed axle,
when the roller is brought to the front of the machine, and by rotating the latter
wheel by hand or power the work is delivered from its roller clear of the machine.
Means are provided for holding the roller in position in the guides, and there may
be gear wheels at both ends of the roller.

Improvements in and relating to Work Rollers for Lace Machines.
FRANK NEWTON HOBSON 11 Beech Avenue Sherwood Rise, Nottingham
Machine Builder 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:-
This invention relates to improvements in and relating to work rollers for lace
machines, and has for its object the provision of means for enabling the work roller
to be brought to the front part of the machine when it is required to remove the
work from the same aud means whereby the work roller may be rotated when in
its forward position. In the ordinary work roller arrangement the work as made
is taken up by a porcupine roller and is wound upon the work roller this latter
resting on the former and being rotated by it. When the work roller is filled, or
for any other reason it is required to remove the work, the attendant has to lift

page_text: the work roller clear of the porcupine roller and pull the work by hand to unroll
it from the roller. There was with this arrangement a liability of the work being
torn or distorted, and that it would become entangled with the machine or come in
contact with the porcupine roller.
Now according to this invention the porcupine roller is mounted and actuate.l ns
in an ordinary arrangement, and the work roller is driven for winding up the
work by contact with the porcupine roller. The work roller guides have the
usual upright slot and in addition have horizontal slots which join the upright
slots, and thus allow of the work roller beiug moved to the front of the machine
after it has been raised sufficiently high. Suitable lovers are used for raising the
work roller and at one or both ends of the same there is a toothed pinion arranged
to gear with a fixed wheel when the roller is in its forward position, and by which
the roller is rotated to unwind the work.
In the accompanying drawings which are hereafter referred to in the following
detailed description of this invention.
Fig. 1. is an end elevation of the improved work roller arrangement, and
Fig. 2 is a front elevation of the same.
The work roller mechanism is carried by end brackets a which are attached to
the machine standards and form bearings for the porcupine roller which consists
generally of a wrought iron tube b covered with carding b. This roller is driven
in the usual way by any convenient arrangement of mechanism.
The work roller c is driven by contact with the porcupine roller b and as the
work accumulates rises in the slot d which forms a guide for the work roller axle.
At the top of the slot d is another slot e and pivotted at fis a lever g 80 arranged
that when the roller c is in its lowest position one end of the lever g can be passed
under the work roller axle. There is a slotted bracket and lever at both ends of
the work roller and when both levers are operated the work roller is raised into
the slots and can then be rolled to the front end of the same in which position it is
secured by pins or pegs . For unwinding the work the end of the work roller
is fitted with a pinion of such a size that it gears into the wheel when the roller
is at the front end of the slot e or there may be gear wheels at both ends of the
roller. Tho wheel is provided with a handle m, and when rotated gives motion
to the roller c from which the work is delivered without the objections to the
existing methods.
Having now particularly described and ascertained the nature of my said invon-
tion, and in what manner the same is to be performed I declare that what I
claim is
1. The combination of a work roller with slotted brackets for guideing it, lovers
for raising it, and gear wheels for rotating it, constructed combined and arranged
as herein shown and described and for the purpose specified.
