PROVISIONAL SPECIFICATION.
Improvements in and connected with Jets for Water and other
Fluids.
We, WILLIAM MATTHEWS, JOSEPH YATES, and WALTER YATES, all of the
firm of Matthews and Yates Limited, Todd Street Works, in the City of
Manchester and County of Lancaster, Sanitary and Ventilating Engineers, do
hereby declare the nature of this invention to be as follows:-
In jets employed for delivering water and other fluids it frequently happens
when the jets are of comparatively small diameter, that they become obstructed or
closed by foreign matters or by corrosion, even when filtered water is used.
The object of this invention is to prevent the obstruction and closing of the
jets, and in the case of such obstruction having occurred through neglect or from
any other reason, to provide for the removal of the obstruction or the opening of
the jet.
According to these improvements we arrange in line with the axis of the jet a
pricker or similar implement in such a manner that, by the rotation of a screw to
which it is secured for example, the implement may be caused to enter the orifice
of the jet and thus clear it. After the jet has thus been cleared, the implement is
withdrawn.
The implement may conveniently be carried on the inner end of a quick
threaded screw within the jet or pipe or chamber to which the jet is connected.
The stem of this screw may pass through a packed gland and be furnished with a
handle, or if the jet is in an inaccessible position, it may be furnished with a
chain wheel and chain or other similar means for rotating the screw.
The end of the screw may also conveniently be constructed to fit upon a seating
formed around the jet and to act as a valve. If this valve is regularly employed
for opening and closing the jet it will be obvious that the orifice will be kept
clean by the resulting frequent insertion of the pricker. Moreover, the pricker
being preferably pointed, may be employed to regulate the quantity of fluid
delivered by the jet, by withdrawing it completely or to a less extent from the
orifice.

COMPLETE SPECIFICATION.
Improvements in and connected with Jets for Water and other
Fluids.
We, WILLIAM MATTHEWS, JOSEPH YATES, and WALTER YATES, all of the
firm of Matthews and Yates, Limited, Todd Street,' in the City of Manchester, and
County of Lancaster, Sanitary and Ventilating Engineers, 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:-
In jets employed for delivering water and other fluids, it frequently happens,
when the jets are of comparatively small diameter, that they become obstructed
or closed by foreign matters or by corrosion, even when filtered water is used.
The object of this invention is to prevent the obstruction and closing of the
jets, and in the case of such obstruction having occurred through neglect or

page_text: from any other cause, to provide means for the removal of the obstruction or
the opening of the jet.
According to these improvements we arrange, in line with the axis of the jet,
a pricker or similar implement, in such a manner that, by the rotation of a screw
to which it is secured, or by other similar means, the implement may be caused
to enter the orifice of the jet and thus to clear it, and then to be retracted clear
of the orifice.
The implement may be combined with a valve, so that the pricker will be
caused to enter the orifice every time the valve is closed.
If the implement is tapered, it may be employed to regulate the volume of
water issuing from the jet, by being caused to enter more or less within the jet
orifice.
We will more particularly describe our said invention with reference to the
accompanying drawing which represents a vertical longitudinal section through
the apparatus.
The pricker A, is fixed upon the inner end of the quick threaded screw B, in
exact alignment with the orifice of the jet C. The stem of this screw may pass
through the stuffing box D, and be furnished at its outer end with a handle or
hand wheel, or, if the jet be in an inaccessible position, the stem may have fixed
upon it a chain wheel and be rotated by means of a chain.
The inner end of the screw B, may also be conveniently constructed to fit
upon and around the orifice of the jet at G, and thus to act as a valve.
If this
valve be regularly employed for opening and closing the jet, it will be obvious
that the orifice will be kept clean by the resulting frequent insertion and withdrawal
of the pricker. Moreover, as already described, the pricker being pointed, may be
employed to regulate the quantity of fluid delivered by the jet, by withdrawing it
completely or to a less extent from the orifice.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same may be performed, we declare that what we
claim is-
1. An apparatus for clearing the orifice of a jet, constructed arranged and
operated substantially as herein before described and as illustrated by the accom-
panying drawing.
2. In an apparatus for clearing the orifices of jets, a pricker in alignment with
the orifice of the jet, and capable of being inserted into and withdrawn therefrom,
substantially as hereinbefore described.
3. In an apparatus for clearing the orifice of a jet, the combination and
arrangement with a pricker in alignment with the axis of the jet orifice, of a valve
on which the pricker is secured, substantially as hereinbefore described and as
illustrated by the accompanying drawing.
