PROVISIONAL SPECIFICATION.
Machinery for the Manufacture of a Substitute for Hay and Straw
Bands.
I, WILLIAM GERSTLE, of Crown Wharf, Grove Street, Deptford, in the County
of Kent, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to machinery for the manufacture of a substitute for hay and
straw bands manufactured from wood wool as described in the Specification of my
application for a Patent No. 23799 of even date herewith.
According to the invention I construct a machine wherein the wood wool is fed
through a guide on to a drum which is rotated so as to twist the wood wool as it is
fed into the machine, the said drum or the guide being reciprocated so that the
manufactured rope or band is coiled evenly thereon.
In a suitable arrangement for effecting the reciprocating movement for evenly
winding the manufactured rope upon the drum 1 mount the said drum upon a
spindle having right and left screw-threads which work in the internally screw-
threaded boss of the drum so that the movement of the drum relatively with the
spindle causes the drum to move along the spindle until it reaches the end of the
screw-threads with which it is engaging, the internal threads upon the boss then
passing into the other screw-thread so that the direction of motion of the drum is
reversed and so on.
Or, instead of reciprocating the drum, I can arrange that the twisted material
passes through a guide which can be reciprocated by suitable gear in front of the
drum upon which the material is wound.

Machinery for the Manufacture of a Substitute for Hay and Straw
Bands.
1, WILLIAM GERSTLE, of Crown Wharf, Grove Street, Deptford, in the County of
Kent, 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 :-
This invention relates to machinery for the manufacture of a substitute for hav

page_text: and straw bands manufactured from wood wool as described in the specification of my
application for a Patent No. 23799 of even date herewith.
According to the invention I construct a machine wherein the wood wool is fed
through a guide on to a drum which is rotated so as to twist the wood wool as it is
fed into the machine, the said drum or the guide being reciprocated so that the
manufactured rope or band is coiled evenly thereon.
In a suitable arrangement for effecting the reciprocating movement for evenly
winding the manufactured rope upon the drum I mount the said drum upon a
spindle having right and left screw-threads which work in the internally screw-
threaded drum so that the movement of the drum relatively with the spindle causes
the drum to move along the spindle until it reaches the end of the screw-threads
with which it is engaging, the internal thread or threads upon the boss then passing
into the other screw-thread so that the direction of motion of the drum is reversed
and so on.
Or, instead of reciprocating the drum, I can arrange that the twisted material
passes through a guide which can be reciprocated by suitable gear in front of the
drun upon which the material is wound.
In the accompanying drawings-

invention:
Figure 2 is an end elevation thereof; and
Figure 3 is a plan of the feed end of the machine:
Figure 4 is a sectional elevation of the modified construction of machine:
Figure 5 is a sectional end elevation thereof; the section being taken on the
line 5-5 Figure 4; and
Figure 6 is a section on the line 6-6 Figure 4 drawn to a larger scale.
Referring first to the machine illustrated in Figures 1 2, and 3 a is the bed of
the machine, the said bed being provided with standards or supports at, al for
receiving the spindle b, . c is the winding drum having end flanges d, e, of which
the flange e is provided with a screw-threaded boss e¹ which screws into the end of the
drum proper so that when the drum has been filled with the wood wool rope,
the said rope can be removed by unscrewing the end flange e and sliding the coiled
rope off the drum c.
The end of the shaft b, which is driven by a belt running on one of the
pulleys f, g is made hollow and the wood wool A is fed through the fixed guide,
through the said hollow portion 61 of the spindle and thence over a guide pulley
which is pivotally mounted in the piece j forming the connection between the solid
portion and the hollow portion 61 of the shaft. From this pulley i the wood wool
is passed over guide pulleys k, k¹ pivotally mounted on a frame bolted to the
connecting part j of the shaft. From the frame the wood wool A is fed on to the
drum c. 2,2 are guide pieces secured to the frame / adjacent to the pulleys ki, k¹
to prevent the rope leaving the said pulleys.
To reciprocate the drum to enable the wood wool to be evenly wound thereon I
form the shaft b with a double or reverse screw-thread with which engages an internal
screw-thread upon the drum, c the said internal thread being preferably in the form
of a short pivoted portion of thread the inclination of which can alter so that it can
engage with either of the 'screw-threads upon the shaft b. Brake blocks m, m are
secured to frames m³, m³, pivotally mounted in bearings m², m², the said brake blocks
being adapted to be pressed against the end flange d of the drum c through the
medium of chains n, n which are attached to the two frames m³, m² at one end above
the bearings m² and at the other end to one end of a chain n' passing over a guide
pulley mounted in bearings n³ secured to the bed a of the machine and being
connected at its other end to a crank n keyed to a rocking spindle n³ mounted in
bearings and adapted to he actuated by the counterweighted pedal n.
The operation of the machine is as follows:-
Assuming the wood wool to have been partially fed on the drum, as shewn in
Figure 1; and the shaft ¹ to be rotated by a belt running on one of the pulleys f, g

page_text: he said drum is pulled round with the frame and the wood wool is twisted by the
Totation of the drum and frame upon the shaft the twisting being, effected from the
guide through which the wood wool A is fed as above mentioned." To draw a further
portion of wood wool into the apparatus and at the same time wind it upon the drum
the pedal is depressed, thereby forcing the brake blocks m against the end flange d
of the drum which is thus held from rotation and is consequently caused to move
axially upon the shaft b by the screw-threaded portion of the said shaft. When the
required length of rope has been wound upon the drum the pedal n is released, thereby
allowing the drum to again rotate with the shaft and so on. When the drum reaches
the end of the screw-threaded portion of the shaft b its axial movement will, as above
described, be reversed and the twisted wood wool will then be coiled on the drum in
the other direction.
Referring now to the arrangement illustrated in Figures 4, 5 and 6 o, o are the
standards of the machine which support the shaft o¹ in bearings of at the upper ends
thereof, the said shaft being provided or made with a frame p and having its end o
formed hollow as shewn.
03 is a stepped pulley by means of which the shaft o can be driven and q is a clutch
which is adapted to be operated by the following mechanism, that is to say, the
forked lever q, the fork of which engages the groove 7° of the clutch, is pivoted to
the bracket q2 and connected at its free end to one end of a link q³ the other end of
which is jointed to a crank g keyed to a spindle q mounted in a bracket q° and
having keyed to it a bevel wheel 7 engaging with a bevel wheel qs mounted upon a
rocking spindle 7 having a double pedal q10 by depressing the ends of which the
spindle is rocked and the clutch q is put into or out of gear. q is a fly wheel
keyed upon the shaft o¹ and 912 is a brake block which slides in a guide q¹ secured to
one of the standards o and is applied to the periphery of the said fly wheel q¹¹ by the
rod q hinged to the lever q' so as to brake the fly wheel when the clutch is out of
gear, as shewn in Figure 4; when the clutch is put into gear by depressing the
pedal q10, the said brake block q12 is withdrawn from the fly wheel 2" thereby leaving
it free to rotate.
is the drum proper having the flanges 1, 2 the latter of which is provided
with a
screw-threaded boss by means of which it can be screwed into the
drum . The flange 1 is provided with clutch teeth which engage
in the teeth of a clutch keyed upon the spindle p' rotatably mounted in one
side of the frame p, the other flange being supported by a spindle p² having keys on
its end to engage therewith and held in position by a split collar and a pin ro
passing through them both. 3, p are two pulleys rigidly connected together and
loosely mounted upon the shaft o¹; the pulley is provided with a brake band p
which is adapted to brake the said pulley through the medium of the chain or cord pe
connected to the free end of the foot board p by depressing which the said brake
hand p can be tightened upon the pulley p³. Over the pulley 24 there runs an
endless cords which passes over the guide pulley 81, thence over the pulley 82 loosely
mounted upon the spindle p', and thence over the guide pulleys and back to the
pulley p. is toothed gearing which is provided to transmit the motion of the
pulley 82 to the spindle p¹ at the required velocity. With this arrangement it will
be obvious that when the pulley p* rotates relatively with the frame p the pulley. 82
and thereby the spindle p¹ and drum r are rotated as hereinafter described.
t is the rope guide, the said guide being movably mounted upon the transverse
slide secured to the frame p. The transverse slide is U or trough shaped in
cross section, as shewn in Figure 6, and is adapted to receive an endless chain t
running over two chain wheels t³ rotatably mounted in the said slide t¹ and one of which
is driven by a bevel wheel gearing with a bevel pinion to mounted upon a shaft t
supported in bearings 7 (Figure 5) on the frame p and slide t¹ and adapted to be
driven by gear wheels ts from the spindle p². The chain t2 is provided with a pin u
which extends into, and engages with, a transverse slot or groove u³ on the underside
of the reciprocating guide t, so that when the chain is rotated by the spindle p²
through the medium of the above described mechanism, the said guide is reciprocated

page_text: in front of the drum. The portion of the guide t through which the material is fed
comprises the spherical portion which is mounted in a spherical socket vl in the
guide piece t so that the said spherical guide v can turn in the socket v₁ to compensate
for the movement of reciprocation of the guide.
w is the fixed guide through which the wood wool is fed, the said fixed
guide being formed upon a bracket w secured to one of the standards o of the
machine.
The operation of this construction of apparatus is as follows:-
5°
The wood wool fed through the fixed guide w passes through the hollow shaft o° and
through the sperical guide on to the drum r. When, therefore, the shaft o¹ is
rotated in the usual manner (the brake band not being applied) the whole of the
frame protates but the pulley 82 is not rotated as the pulley p turns with the said
frame p; the material is, therefore, twisted but the twisted rope is not wound upon
the drum. To wind a length of the twisted material upon the drum the brake
band p is tightened by means of the foot board p so that the pulley 24 is prevented
from rotating; the frame p then rotates relatively with the pulley p4, thereby causing
the cord & to turn the pulley s² and rotate the drum through the medium of the
intermediate gear &; the rotation of the drum also causes the chain t² to rotate, as
above described, thereby reciprocating the guide & in front of the drum, the wood
wool being wound upon the said drum and being drawn through the fixed guide w.
The operation is continued intermittently in the manner above described until the
drum is filled. The parts 70, 75 and p² are then removed so as to enable the drum to
be withdrawn from the frame p and the coil of rope is removed by taking off the
flange r².
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The improved apparatus for manufacturing wood wool bands constructed
substantially as hereinbefore described and illustrated in Figures 1, 2 and 3 of the
accompanying drawings.
2. The improved apparatus for manufacturing wood wool bands constructed sub-
stantially as herein before described and illustrated in Figures 4, 5 and 6 of the
accompanying drawings.
