Improvements in Means for Supporting and Rotating Barrels,
Cylinders, and the like.
We, JOHN FREDERICK WEBB, of 83, Bridge Road, Battersea, in the County of
Surrey, Engineer, JOSEPH EDWARD LILLEY, of The Chestnuts, Wealdstone, in the
County of Middlesex, Gentleman, and JOHN CHAPMAN, of St. Mary's Road, Ealing,
in the County of Middlesex, Gentleman, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the supporting and rotating of barrels, cylinders,
and the like, such as are used in the arts; for example in the treatment of mineral
matter in metallurgical operations, and has for its object the provision of means
for such purpose in a simple cheap and effective manner.
In rotating devices of this nature at present in use, the barrel or cylinder is
mounted upon an axle, which passes through the body of the same and is adapted
to rotate in bearings. This form of construction involves the ends of the barrel
or cylinder being made to take the whole of the load, both of the weight and
the turning effort; hence such construction is costly.
This invention consists in supporting the barrel or cylinder upon two or more
slings, of flexible material, which pass round the body thereof.
These slings preferably run in grooves, which may be formed upon, or integral
with, the bonding hoops; or equivalently special rings may be provided for the
purpose.
We arrange a shaft, supported in bearings carried by a suitable framework,
and upon this shaft we fix two or more grooved or plain pulleys, one pulley to each
sling, and we place the barrel under the said shaft with its slings upon the pulleys
on the said shaft.
If now the shaft be rotated the pulleys will revolve the barrel through the
medium of the slings that are supporting the said barrel.
We have found that steel wire rope is a suitable material for the slings, as it
is very strong, flexible, and of low cost.
We may arrange the slings in such a way and of such a number as to properly
support the barrel along the whole length of its body.
By supporting the barrel thus, it need only be made strong enough to with-
stand the strains from its contents and its own weight, as the slings take the
weight and exert the rotative effort over a very considerable part of the structure.
Further the working of the device is very smooth, without jar, or vibration,
and is adaptable to varying conditions by arranging the ratio of the diameters of
the pulleys and barrel to one another.

We, JOHN FREDERICK WEBB, of 83, Bridge Road, Battersea, in the County of
Surrey, Engineer, JOSEPH EDWARD LILLEY, of The Chestnuts, Wealdstone, in the
County of Middlesex, Gentleman, and Joux CHAPMAN, of St. Mary's Road, Ealing,
in the County of Middlesex, Gentleman, do hereby declare the mature 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 the supporting and rotating of barrels, cylinders,
and the like such as are used in the arts, for example, in the treatment of mineral
matter in metallurgical operations, and has for its object the provision of means
for such purpose arranged in a simple, cheap and effective manner.
In rotating devices of this nature at present in use, the barrel or cylinder is
mounted upon an axle, which passes through the body of the same and is adapted
to rotate in bearings. This form of construction involves the ends of the barrel
or cylinder being made to take the whole of the load, both of the weight and
the turning effort, hence such construction is costly.
This invention consists in supporting the barrel or cylinder upon two or more
slings of flexible material, which pass round the body thereof, so arranged as to
take the load of the barrel in a distributed manner.
These slings preferably run in grooves, which may be formed upon or integral
with the bonding hoops or equivalently special rings may be provided for the
purpose.
In order that this invention may be the better understood we will now proceed to
describe the same in relation to the accompanying drawings hereunto annexed
reference being had to the letters and figures marked thereon. Like letters refer
to like parts in the various figures.
Figure 1, is a front elevation of a barrel supported according to our invention.
Figure 2, is an end elevation of the same.
Figure 3, is a front elevation of barrel supported on pulleys having independent
axes and operated by a driving gear common to all the pulleys.
Figure 4, is an end elevation of the sam.
To carry our invention into effect we arrange a shaft A supported in
bearings B carried by a suitable framework C and upon the shaft A we fix two
or more grooved or plain pulleys D) the number varying according to be supported,
one pulley to each sling, and we place the barrel E under the said shaft A with
its slings Fupon the pulleys D on the said shaft A. Means are provided for
driving the shaft A such as a pulley G.
If now the shaft A be rotated the pulleys D will revolve the barrel E through the
medium of the slings F that are supporting the said barrel E.
We have found that steel wire rope is a suitable material for the slings F as
it is very strong, flexible, and of low cost.
We arrange the slings F in such a way and of such a number as to properly
support the barrel E along the whole length of its body, the barrel illustrated in
the drawing has bonding hoops H formed with a groove thereon for the ropes.
By supporting the barrel thus, it need only be made strong enough to with-
stand the strains from its contents and its own weight as the slings take the
weight and exert the rotative effort over a very considerable part of the structure.
Further the working of the device is very smooth, without jar or vibration,
and is adaptable to varying conditions by arranging the ratio of the diameters
of the pulleys and barrel to one another.

page_text: As in the cases of barrels or the like of large size, for example having a capacity
of 100 tons, it is a matter of some difficulty to make all the slings of exactly the
same length, with the consequence that when used with one supporting shaft
common to all the pulleys, uniform and proper distribution of the load is not
obtained. To overcome this defect we carry out our invention as shown in
Figures 3 and from which it will be seen that the pulleys D are mounted upon
independent shafts A¹, the said shafts being supported on independent plummer
blocks B which are capable of independent vertical adjustment in order that
each sling may be made. to takes its proper proportion of load. This adjustment
may be made by inserting packing pieces between the blocks and the surface
supporting them. The pulleys D are provided with means for being driven,
such as cog wheels J which are geared into a series of spur wheels K fixedly
attached to a shaft L mounted on bearings M at the back of the pulleys D. The
shaft L is provided with a driving pulley G.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
-
1st. Improved means for supporting and rotating barrels, cylinders and the like,
consisting of a shaft adapted to be rotated, two or more flexible slings carried by the
said shaft or by pulleys on the said shaft, in which slings the barrel or like device is
hung so as to be properly supported in a distributed manner and revolved by the
movement of the slings around the said shaft, substantially as described.
2nd. In combination, a barrel, cylinder, or the like having grooved bonding
hoops or circumferential bands, two or more flexible slings and a shaft with or
without pulleys adapted to rotate and carry the said barrel or the like by means
of the said slings, substantially as described.
3rd. In combination, a barrel, cylinder or the like, a series of pulleys or the like
each carried on an independent shaft mounted in an adjustable manner flexible
slings for carrying the barrel or the like passing round the said pulleys, so as to
distribute the supports along and around the barrel and means for simultaneously
transmitting movement to the said pulleys substantially as described.
