PROVISIONAL SPECIFICATION.
An Improved Construction of Metallic Travelling Sheet or Apron
for Use in Machines for Drying Wool, Cotton, Hanks of Yarn,
Tea, and other Materials.
1, WILLIAM WHITELEY of the Firm of William Whiteley and Sons Limited
of Lockwood near Huddersfield in the County of York, Machine Makers, do
hereby declare the nature of this invention to be as follows:-
This invention has reference to the manufacture or construction of endless
travelling sheets or aprons employed in machines for drying wool, cotton, hanks of
yarn, tea, and other materials.
In constructing the sheet or apron for the above purposes according to my
invention, I employ endless chains at each side of the machine connected together
by horizontal crossbars or wires. I also employ several sets of other bars or links
arranged parallel with the endless chain, the ends of each link terminating with
one of the horizontal cross wires arranged opposite the joints or hinges of each of
the links in the chain. These links are placed at suitable distances apart according
to the strength and width of carrying apron to be made.
By constructing a carrying apron of cross bars or wires in connection with
endless chains and by the additional employment of links terminating on what may
be called the joint wire, these carrying aprons will be strong substantial and
durable. They will also bend or curve to the periphery of rollers around which
they have to pass in travelling through a drying machine.

CURPLEIE DI MULTICATION
An Improved Construction of Metallic Travelling Sheet or Apron
for Use in Machines for Drying Wool, Cotton, Hanks of Yarn,
Tea, and other Materials.
1, WILLIAM WHITELEY, of the Firm of William Whiteley and Sons, Limited,
of Lockwood, near Huddersfield, in the County of York, Machine Makers, 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 has reference to the manufacture or construction of endless
travelling sheets or aprons employed in machines for drying wool, cotton, hanks of
yarn, tea, and other materials.
In constructing the sheet or apron for the above purposes according to my
invention, I employ endless chains at each side of the machine connected together
by horizontal cross bars or wires. I also employ several sets of other bars or links
arranged parallel with the endless chain, the ends of each link terminating with

page_text: one of the horizontal cross wires arranged opposite the joints or hinges of each
of the links in the chain. These bars or links are placed at suitable distances
apart according to the strength and width of carrying apron to be made.
With reference to the drawings --
Fig. 1 is sectional elevation of my improved metallic travelling sheet or apron
taken through line a-b of Fig. 2, which is plan of same.
Fig. 3 is section taken through line e-d of Fig. 2 and Fig. 4 is another section
taken through line e-f of Fig. 2, and Fig. 5 shews one arrangement of my endless
travelling sheet or apron as employed in machines for drying wool, cotton, hanks
of yarn, tea and other materials. g represents endless chains arranged at each side
of the machine and preferably sliding in grooves formed in the horizontal plates h
and i, whereby the endless sheet is kept at one uniform tension with regard to
width. At the inner side of the links are cast or otherwise fastened plates j
'provided with a suitable number of holes or openings to receive the ends of the
wires or cross bars l, the ends of the said wires being made secure to the platej by
a clamp or plate in secured by screw n. The wires or cross bars also pass
through links o and p to strengthen and also to assist in keeping the travelling
sheet Hat.
An important feature of my invention has reference to the horizontal cross bars
or coupling wires A, each end of which enters into the hollow joint or hinge of the
'links g. An enlarged view Fig. 6 illustrates more clearly the mauner in which the
links are joined together. A hollow revit or tuber is passed through the links as
shewn. The ends of the cross. bars A are inserted into one end of the hollow revit
or tube and prevented from working end wise by the screws S as shewn in the
drawings.
These bars A not only strengthen the endless sheet but with their ends 'lodging
in the joints of the links of the chains, they become fulcrums when the chains are
passing over the peripheries of rollers.
By constructing a travelling apron of cross bars or wires in connection with
endless chains and by the additional employment of links o and p. terminating on
what may be called the joint wire A this carrying apron is strong, substantial and
durable, and there is no drag or pull upon the cross bars but only upon the chains;
there is therefore no stretching of the apron as is the case with inetallic chains
hitherto employed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. The construction of a metallic chain or apron comprising cross bars
links o, p, and endless chains g as shewn and described herein.
Secondly. The construction of a metallic chain or apron comprising crossi bars.
..links o, p, and endless chains g in combination with cross bars such as A. as, shewn
and described herein.
