Improvements in Apparatus for the Prevention of Accidents with
Straps and Drums.
We JOHN QUARMBY of Bridge Gate, Milnsbridge near Huddersfield Grocer, and
WILLIAM HALL of Whiteley Bottom, Milnsbridge near Huddersfield, commercial
traveller do hereby declare the nature of this invention to be as follows:-
The object of this invention is the prevention of accidents in factories and workshops
which take place in connection with the straps and drums.
It oftens happens that a strap slips off the drum and falling upon the revolving
shaft is caught and gathered up by it and does much damage, frequently entailing loss
of life, and our invention is intended to prevent this danger.
Our invention consists in placing a tube or sleeve of wood or metal or if necessary
two or more of such tubes of suitable length upon the shaft upon each side of the
drum and close up to it, the shaft running through the said tube or tubes. These
tubes have an interior diameter rather larger than that of the shaft upon which they
are placed, so that although they ordinarily revolve with the shaft they only fit it
loosely, and are at once brought to rest by a slight pressure, as they are not attached
to the shaft in any way.
If the strap should slip off the drum it would thus fall not upon the shaft but upon
the loosely fitting tube which would at once be brought to rest by the weight of the
strap. The strap itself would be protected from injury and could not be gathered up
and cause any damage.
The tube as above described would also act as a protection and guard to work-
people employed in putting straps upon drums, and prevent their being drawn in and
entangled with the strap and shaft.
We would preferably make these tubes in two halves longitudinally, and of wood,
with a projecting flange at each end, but the shape and material would naturally require
to be modified by circumstances.

We JOHN QUARMBY of Bridge Gate, Milnsbridge near Huddersfield grocer, and
WILLIAM HALL of Whiteley Bottom, Milnsbridge near Huddersfield commercial
traveller 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 :-
The object of this invention is the prevention of accidents in factories and workshops
which take place in connection with the straps and drums. It often happens that a
strap slips off the drum and falling upon the revolving shaft is caught and gathered
up by it, and does much damage frequently entailing loss of life, and our invention is
intended to prevent this danger.
Our invention consists in placing a tube or sleeve of wood or metal or if necessary
two or more of such tubes of suitable length upon the shaft upon each side of the
drum and close up to it, the shaft running through the said tube or tubes. These
tubes have an interior diameter rather larger than that of the shaft upon which they
are placed, so that although they ordinarily revolve with the shaft, they only fit it
loosely, and are at once brought to rest by a slight pressure, as they are not attached
to the shaft in any way. If the strap should slip off the drum it would thus fall not
upon the shaft, but upon the loosely fitting tube which would at once be brought to
rest by the weight of the strap. The strap itself would be protected from injury, and
could not be gathered up and cause any damage.
The tube as above described would also act as a protection and guard to work people
employed in putting straps upon drums and prevent their being drawn in and
entangled with the strap and shaft.
We would preferably make these tubes in two halves longitudinally, and of wood
or malleable iron with a flange at each end, but the shape and material would naturally
require to be modified by circumstances.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :
The use of a tube or sleeve as above described for the prevention of strap
accidents.
