PROVISIONAL SPECIFICATION.
Improvements in the Burring Apparatus of Carding and similar
Machines.
I, JOHN VARLEY MUSGRAVE, of 33, Legrams Terrace, Listerhills, near
Bradford, in the County of York, Mechanic, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in the burring apparatus of carding and
other similar machines in which the burrs or the like are struck off or separated
from the fibres by revolving beaters or the like and are thrown into a tray or other
suitable receptacle and its object is to provide mechanism of simple construction to
automatically remove the burrs from such tray.
For this purpose I employ a travelling brush or its equivalent to sweep the said
tray. This brush is fixed on or secured to an endless band, chain or belt arranged
above the tray and approximately parallel to it and mounted on suitable driving
and guide rollers. The said endless band is preferably driven by a worm mounted
on the shaft of the beater engaging a worm wheel fixed to the said driving roller.
When the machine is in operation the brush secured to the endless band passes
along either in contact with or in close proximity to said tray and sweeping the
burrs aside or along with it may drop them off the end where a suitable receptacle
may be provided to receive them.

COMPLETE SPECIFICATION.
Improvements in the Burring Apparatus of Carding and similar
Machines.
I, JOHN VARLEY MUSGRAVE, of 33, Legerams Terrace, Listerhills, near
Bradford, in the County of York, Mechanic, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascerained in and by the following statement :-
This invention relates to improvements in the burring apparatus of carding and
other similar machines in which the burrs or the like are struck off or separated
from the fibres by revolving beaters or the like and are thrown into a tray or other
suitable receptacle and its object is to provide mechanism of simple construction to
automatically remove the burrs from such tray.
For this purpose I employ a travelling brush or its equivalent to sweep the said
tray. This brush is fixed on or secured to an endless band chain or belt arranged
above the tray and approximately parallel to it and mounted on suitable driving
and guide rollers. The said endless band is preferably driven by a worm mounted
on the shaft of the beater engaging a worm wheel fixed to the said driving roller.
Reference is to be had to the accompanying sheet of drawings forming a part
of this Specification in which similar letters of reference indicate corresponding
parts in each of the figures.
Figure 1, represents a plan view of such parts of the feed end of a carding machine
as are necessary to illustrate the application of my improvements.
Figure 2, is a front view of the same with a portion of the back of the tray shown
broken away to show the endless band in full, and the beater is omitted.
Figure 3, is a side view.

page_text: The licker-in A, the beater B, and the tray C are of any ordinary construction
and the beater B is mounted in bearings D, and D secured to the pedestal
standards E in the ordinary manner. A bracket F is mounted upon the outside of
the bearing D and secured thereon by the set screw G and the projecting piece H
of the bracket carries the adjustable horizontal piece J having a bearing K at its
extremity for the short shaft L. This short shaft is rotated by the worm wheel W
secured to one end engaging the worm M fixed on the arbor N of the beater and
the pulley O is secured on the other end of the shaft L. A similar pulley O' at
the other end of the tray C is mounted upon the stud P fixed to the bracket F¹
secured to D¹ and an endless band R is mounted upon these two pulleys. A brush
or scraper is mounted upon this band in the drawing a scraper S is shown.
The various parts are so relatively arranged that as the pulley O is operated from
the arbor N through the medium of the worm M and the worm wheel W the
endless band R is continuously operated and the scraper S sweeps along the tray
and carries the burrs along with it eventually dropping them off the end T of the
tray which is extended so as to drop them clear of the machine.
Two or more scrapers may be used and they are preferably inclined from back
to front as shown in the drawings for the purpose of keeping the burrs carried along
thereby at the back of the tray.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is:
:--
1. In a carding or similar machine, the combination with a burr tray or similar
receptacle, of an endless band having one or more sweepers or scrapers adapted to
remove the burrs and the like from the tray, substantially as herein shown and
.described.
2. The combination with the endless band or chain, of a driving pulley operated
by a worm wheel engaging a worm on the arbor of the beater, substantially as
herein shown and illustrated in the accompanying drawings.
