Improvements in Conveyers for use in connection with Wood Cutting
and Working Machines.
We, JOSEPH SCAIFE, of South Street Saw Mills, Keighley, in the County of York,
Timber Merchant, and RICHARD WOOD, of 9, Highfield Lane, Keighley, aforesaid,
Engineer, do hereby declare the nature of this invention to be as follows, that is
to say :-
In connection with wood cutting and working machinery, particularly of
wood under
the class whereby long shavings are cut from the boards or
operation, considerable difficulty has been experienced and expense incurred
in conveying such shavings or refuse away from the machines, and the object of
this invention is to produce means whereby such difficulties may be entirely over-
come and at comparatively little expense.
To attain this object, use is made of the well known fan and conduit arrangement
so as to extract and convey, by a current of air, all such parts or refuse from the
machines as will pass through the fan and along said conduit, such arrangement
and construction of apparatus being old and well known. However, in order to
be enabled to convey or carry away the long shavings or like refuse, a pair of
rollers are mounted in the walls of the conduit or in suitable proximity therewith
and motion is imparted to these rollers so that they will lay hold of, drag and force
said shavings and the like from the outside and cause them to pass into the con-
duit as desired, along which they are carried with the current of air together with
the other refuse above referred to.
These rollers are constructed so that their surfaces, which are in contact with
each other, will form a joint which is somewhat air-tight by which means any
undesirable escape of air from the conduit is prevented, while appropriate pressure
springs with their necessary adjusting mechanism are used in connection with said
rollers to enable them to be moved in accordance with the thickness of shavings
or refuse passing between them.
The walls, of the air conduit, bearings for the rollers and other parts in con-
nection therewith are so formed as to prevent leakage from the current of air, as
well as to enable the shavings and refuse to be readily gathered and forced into
said current.

We, JOSEPH SCAIFE, of South Street Saw Mills, Keighley, in the County of York,
Timber Merchant, and RICHARD WOOD, of 9, Highfield Lane, Keighley aforesaid,
Engineer, 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, that is to say:-
-
In connection with wood cutting and working machinery, particularly of
the class whereby long shavings are cut from the boards or wood under
operation, considerable difficulty has been experienced and expense incurred
in conveying such shavings or refuse away from the machines, and the object of
this invention is to produce means whereby such difficulties may be entirely over-
come and at comparatively little expense.
In order that our said invention may be readily understood we have hereunto
appended a sheet of drawings illustrative thereof to which by figures and letters
reference is made in the following description wherein:-
Fig. 1 is an elevation of a sufficient portion of a planing machine and conduit
leading from it to show the application of our invention.
Fig. 2 is a view of same as seen from above.
Figs. 3, 4 and 5 are views of parts (drawn to an enlarged scale) hereinafter
described.
To attain the object of our invention we make use of the well known fan (a)
and conduit (b) arrangement so as to extract and convey, by a current of air, all
such parts or refuse from the machines c as will pass through the fan a and along
said conduit b said arrangement and construction of apparatus being old and well
known. However, in order to be enabled to convey or carry away the long shavings
or like refuse, a pair of rollers d f are mounted in the walls of the conduit bor
in suitable proximity therewith and motion is transmitted to these rollers d f as by
the belt g pulley h and gearing wheels km, so that they will lay hold of, drag and
force said shavings and the like from the outside of and cause them to pass into
the conduit as desired, along which they are carried with the current of air to-
gether with the other refuse above referred to.
The rollers d f are constructed so that their surfaces, which are in contact with
each other, (as at p) will form a joint which is somewhat air-tight, by which
means any undesirable escape of air from the conduit is prevented while appro-
priate pressure springs s with their adjusting screws t and dies ware used in con-
nection with said rollers to enable them to be moved in accordance with the thick-
ness of shavings or refuse passing between them.
The walls of the air conduit, as at r, the bearings for the rollers d f and the
other parts as the shoots y in connection therewith are so formed as to prevent
leakage of the current of air as well as to enable the shavings and refuse to be
readily gathered and forced into said current.
In order to increase the gripping powers of the rollers d f their peripheries may
be fluted as shown by Fig. 5, while to clean said rollers and free them of all dirt
or sticky substances that might adhere to them, we mount the rubbing blocks z z¹
to be pressed into contact with said rollers by their springs 2 also shown by Fig. 5.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. In conveyers of the class described, a pair of rollers. means for rotation

page_text: rollers and parts for supporting same arranged in combination substantially as
herein specified.
2. In conveyers of the class described, a pair of rollers mounted to rotate in
the walls of the conduit through which a current of air is flowing substantially as
and for the purposes specified.
3. In conveyers of the class described, a pair of rollers mounted to rotate and
means for cleaning or freeing said rollers from dirt or sticky matter substantially
as specified.
4. The improved parts or apparatus constructed and arranged substantially as
herein specified.
