Leather Belts or Bands.
We JOSEPH HALL of Burley Engine Works Kirkstall Road Leeds in the County
of York Engineer, and ANN HALL of Dyson House Burley near Leeds in the County
of York do hereby declare the nature of this invention to be as follows:-
The object of our Invention is:-1° To provido means for rendering uniform, tho
speed of the leather passing through coiling and edge burnishing machines, as the
leather is being operated upon by the cutters or burnishers, or is being passed
through the machine merely for the purpose of being formed into a coil. In machines
as at present constructed, the band or belt is coiled round a shaft after passing the
cutters and burnishers. This shaft rotating at a uniform speed coils the band or belt
upon it at an increasing speed, and when the machine is operating upon long lengths
of such band or belting, either in one piece or formed by sewing rivetting or
cementing two or more pieces together, this high speed is in itself objectionablo, and
in the latter case especially throws sudden and severe shocks on both the machine and
belt every time the junction of two such pieces passes between the presser plates
and rollers.
Now in order to remove this disadvantage we provide a hinged lever or arm, which
is moved by the coil as it increases in diameter, and this lever or arm is arranged
through suitable mechanism to actuate a rack. A belt passing round a cono pulloy
on the counter or main shaft, and also round a second reversed cone pulley on the
machino, is moved to and fro along the pulleys by a belt guide attached to the before
mentioned rack. The speed of the countershaft being uniform, that of the cone
pulley shaft of the machine is varied by moving the belt as just described; and as the
shaft on which the belt or band is coiled is actuated by the last mentioned cone pulley
shaft, the speed of rotation of the coil shaft is suitably diminished as the diameter of
the coil increases, and the passage of the belt between the burnishers and cutters is
rendered uniform.
Instead of employing the lever above mentioned as operated by the coil, we some-
times provide a sliding piece, which is moved by the increasing diameter of the coil.

page_text: The sliding piece is made to operate a series of lovers or an epicyclic train or
mechanism similar to that above referred to, interposed between it and the belt guide
of the cone pulleys. Where the thickness of the leather to be coiled is always the
same, the proper reduction of the speed of rotation of the coil shaft may be effected
by spur and worm gearing, from the coil shaft or other part of the machine moving
at some fixed ratio of speed of coil shaft.
In some cases we propose to control the speed by causing the above mentioned
lever or sliding piece to act more or less directly on the governor of the motor.
The same effect as is obtained by a pair of reversed cones may be obtained by one
cone and drum, suitable provision being made for keeping the belt tight.
In place of the above mentioned doublo cone pulley, we also propose in some cases
to use a differential arrangement of roller and disc, or a spiral fusee arrangement
interposed between some (uniform) moving part of the machine and the coil
shaft.
Another method for obtaining an approximate uniform motion or speed of the belt
as it is being passed through the machino, is to interpose between the coil shaft and
some other part of the machine having a uniform speed a friction clutch, which
allows the necessary slip to occur for reducing the speed (in revolutions) of the coil
shaft. This arrangement also to some extent serves the second object aimed at by our
improvements.
2° Our Improvements refer to means for ensuring a uniform tension on the band
or belt when passing through the machine, and whilst being acted upon by the
burnishers. For this purpose we arrange the burnishers to reciprocate alternately,
so that one is making a forward motion whilst the other is making a movement in the
opposite direction, the effect of each burnisher is neutralized by the other, and a
uniforn tension is attained. The same effect is caused by making the rotary motion
of the burnishers alternately reciprocating.
3° Our Improvements refer to the combination in one machine of presser plates
and rollers for the purpose of avoiding the necessity of passing the leather through
separate machines.
And lastly to a relief arrangement, so as to allow the coil to be readily unshipped
from the coil shaft. For this purpose the coil shaft is made in two parts connected
together in such a manner however, that the connection can be readily loosened, and
one or both halves withdrawn sideways, enabling the belt to bo quickly removed, and
another connected and started in the machine.

We, JOSEPH HALL of Burley Engine Works, Kirkstall Road Leeds, in the County
of York Engineer and ANN HALL of Dyson House, Burley, near Leeds in the County
of York, 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:―
In the accompanying drawings Fig. 1 is a front elevation. Fig. 2 a side elevation.
Fig. 3 a plan looking at the top, and Figs. 4, 5, 6, 7 and 8 show details, constructed
in accordance with our invention.
The objects of our invention are:
First. To provide means for ren lering uniform the speed of the leather passing
through coiling and edgo burnishing machines, as the leather is being operated upon
by the cutters or burnishers, or is being passed through the machine merely for the
purpose of being formed into a coil. In machines as at present constructed the band
or belt is coiled round a shaft after passing the cutters or burnishers. This shaft
rotating at a uniform speed coils the band or belt upon it an increasing speed, and
when the machine is operating upon long lengths of such bands or belting, either in
one piece, or formed by sewing, rivetting or cementing two or more pieces together,
this high speed in itself is objectionable, and in the latter case especially throws
sudden and severo shocks on both machine and belt every time the junction of two
such pieces pass between the plates and rollers.
A is the framework of the machine, B is the drum or barrel on which the belting
is coiled in the coiling and edge burnishing machines, such machine for the most
part being of ordinary construction.
Now in order to remove the disadvantages above mentioned, we provide the levers
or arins C mounted on the shaft D; the free ends of such levers or arms Care con-
nected by a roller or bar E which rests upon the outer coil, and rises or moves
radially as the coil increases in diameter. This movement causes the shaft D to
revolve which puts in motion the gearing F, actuating the rack pinion G, gearing
into the rack H, causing thereby the rack to travel_horizontally. This movement is
also simultaneously imparted to an overhead rack J, through rack pinions K and L
and vertical shaft M. Motion is imparted for the purpose of coiling the belt through
cone N and gearing O through the drum or barrel B, being transmitted by a suitable
belt from upper cone pulley P on the main driving or countershaft R, and for the
purpose of regulating the speed of the coil barrel or drum B as the coil increases in
diameter we attach to the back of the lower and upper racks H and J, the belt
forks S and T, these move the belt along the cones by the action of the racks H and J,
thus reducing the speed of the coil drum or barrel B in proportion to the increasing
diameters of the coils, and thus regulating to a uniform speed the feed of the coiling
belt. In this arrangement the speed of the cone P on the countershaft is not
varied

page_text: We also when preferred employ the hereinbefore mentioned levers or arms C for
regulating the speed of other driving apparatus or motors, which may be employed
for imparting motion to the abovementioned coiling and burnishing machines; as for
instance at Figs. 4 and 5 in which U is a friction plate to which motion is imparted
through a frictional runnor V on the driving shaft W, the frictional runner being
caused to move across the face of the friction plate U by means of a lever X on the
shaft D, this being caused to move simultaneously with the lovers or arms C, and
thus by moving the runner V on the driving shaft W towards the centre of the
friction disc, reduces the speed thereof in proportion to the increasing size of
the coil.
The above described arrangement of lovers or arms C also may be employed for
regulating the speed of the prime mover, by being connected with the governors, or
other apparatus employed for regulating the speed of the motor.
Instead of the hereinbefore mentioned levers or arms C, a worm and worm wheel
may be employed in connection with the coiling shaft, or a sliding piece may actuate
the rack, such sliding piece being controlled in the same manner as the aforesaid
radial arm C.
Secondly. Our improvements refer to means for ensuring a uniform tension on the
band or belt when passing through the machine and whilst being acted upon by the
burnishers. For this purpose we arrange the burnishers 1 and 2 to reciprocate
alternatoly in opposite directions, so that one is making a forward movement whilst
the other is making a backward movement, the effects of frictional contact of each
burnisher is neutralized, and a uniform tension obtained; this applys to the burnishers
whether thoy be direct, as shown at Figs. 1. 2 and 3, or rotary as shown at
Figs. 6 and 7. The required reciprocating movement is imparted to the burnishers
from any suitable moving part of the machine.
Thirdly. In combination with the coiling and burnishing machine we employ
presser plates 3 and rollers or guides 4, for the purpose of avoiding the necessity of
passing the leather through a separate inachino, for pressing the joints.
And lastly to a relief arrangement, so as to allow the coil to be readily unslipped
from the barrel or drum B. For this purpose the barrel or drum B is made in two or
moro parts 5 and 6, kept in position outwards by rings 7, and hold in the frame by
adjustable cones 8 and 9 as shown at Fig. 8, so that the connection can be readily
loosened and one or more parts of the drum or barrel withdrawn sideways or inwards,
enabling the belt to bo quickly removed, and another connected and started in the
machine.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed wo declare that what
we claim is :-
―
1st. A belt coiling and edge burnishing machine having an arrangement of
apparatus for regulating the speed of the motor or driving apparatus, so as to impart
a uniform movement to the coiling belt, substantially as herein set forth.
2nd. The means employed for imparting a uniform tension to the belt, when
passing between the burnishers, substantially as herein set forth.
3rd. The arrangement and construction of coil drum or barrel, in such a manner
that the coil may be readily released from the machine, substantially as herein set
forth and shown at Fig. 8.
