PROVISIONAL DI PUITIVATION.
Improvements in Belt Guards.
I, GERALD RAYNER GAUNT, of Summerfield, Bramley, in the County of
York, Worsted Spinner, do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements in belt guards, and has for its
object, the construction of the same in such a manner that, whilst protecting the
leading side of the pulley, that is, the side receiving the belt, in such a manner that
a person cannot be accidently caught and injured by the belt and pulley; one or
both sides of the guard is or are made to yield when removing the belt, thus
affording facilities for the quick removal of the same..
The guards are formed so as to enclose pullies for some distance round the
circumference, and for some distance down the one or both sides towards the centre
of the pullies, a portion of one or both side plates of each guard is hinged thereto
and kept in line with the other portion of the side plate by means of a weight or
spring, so arranged that on removing the belt, the hinged portion is allowed to
yield in a manner for allowing the belt to be readily removed.
Dated this 2nd day of June 1892.

COMPLETE SPECIFICATION.
Improvements in Belt Guards.
I, GERALD RAYNER GAUNT of Summerfield, Bramley, in the County of
York, Worsted Spinner, 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 relates to certain improvements in belt guards, and has for its
object, the construction of the same in such a manner that, in addition to the guard
protecting the leading side of the pulley, that is the side receiving the running
belt, a person cannot be accidently caught and injured by the belt and pulley,
and to so form the sides of the guard that, on the belt being pressed against the
same it will yield and thus afford facilities for the quick removal of the belt.
In describing my invention in detail, reference is made to the accompanying
drawings in which Fig. 1 represents a side elevation of a pair of pullies guarded by
my improved arrangement.
Fig. 2 is a section through the guard on line a. b, and Fig. 3 an end view
of same.
The circles A and B. represent two pullies, and the connecting lines C a belt
around same running in the direction of the arrow. The guards D and D¹ are
supported in any convenient manner, such as for example by a bar E attached
thereto engaging with a socket F secured to the machine frame or other suitable
support.
Each guard is formed with an end plate D' of some depth which is extended for
some distance at D and D' along one or both sides of the pulley towards the centre
of same.
To the side plate D is hinged an extension plate G which is kept in a perpen-
dicular position or in line with the side plate by a spring; in the drawing a spiral
spring S is shown coiled round a bar H with one end attached to the plate D. and

page_text: the other free but pressing against the extension plate G by which it is held in the
required position.
With guards fixed at the lower side of the pulley as at D¹ it is not at all times
necessary to use a spring for keeping the hinged extension plate G¹ in line with
the side plate D', the weight of the hinged plate being in most cases sufficient for
.keeping the plate in the position required.
By guarding the pulley with an end plate D' and on one or both sides as may
be required with side plates provided with hinged extension plates G or G' arranged
as described, the leading side of the pulley is protected, and facilities afforded for
the quick removal of the belt, by reason of the hinged extension plates yielding
when the belt is pressed against same for removal off the pulley.
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.
A belt guard in which a hinged extension plate is combined with the side plate
of the guard and held in the required position substantially in the manner as shown
and described.
