EDWARD ZAHN, 129 Clarence Road, Lower Clapton, Hackney, in the County of
Middlesex, Leather Bag Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My water tap is constructed so as to have the spindle direct over the outlet, the
outlet is the shape of either a V or a half ball, in which works a valve of the same
shape, the valve, spindle and handle are attached to each other and move in a
horizontal position, the upper part of the spindle passes through a stuffing box, the
means employed to open the tap are wheels or rollers, which are attached to the valve
and by a turn of the handle will carry the valve out of its resting place, by the wheels
rolling up a groove in the outer case.

page_text: I EDWARD ZAHN, of 129 Clarence Road, Lower Clapton, Hackney, in the county
of Middlesex, Leather Bag Manufacturer, do hereby declare the nature of my
invention for "AN IMPROVED WATER TAP and in what manner the same is to be
performed, to be particularly_described and ascertained in and by the following
statement:-
The intention of this invention is, to provide a tap for water or other liquids, which
shall prevent waste and be durable as also lasting in its actions; to arrive at this
desired end, I have constructed the following:---
Fig. I. My Water Tap is constructed so, as to have the valve C, with the spindle A,
work direct over the outlet B: this drawing represents the tap as closed, in opening
it, the stud E, will by the turn of the handle G, make its way up the groove F, to illu
place of a, the 1 as E, will perform the same move in a corresponding opposite
groove and carry the valve with it, (to which the studs E and I are attached) from
its resting place and so open the tap for the outlet; the stuffing box H, is well
arranged with leather and indiarubber washers, to prevent any upward escape of
water and the valve to prevent corrosion is covered with leather, also to check the
pressure of water and the possible concussion arising therefrom, a plate I, is placed or
fixed on spindle A, or valve C, this plate or sheet will partly or wholly stop the inflow,
while in the act of closing the tap, thereby reducing the pressure on the valve C.
Fig. 11. The tap may also be made, as this drawing represents the action of Fig. I,
reversed, so as G and A, will be in an upside down position to Fig. I, whereby the
spindle A, passes through the nozzle or outlet B, without interfering with the free
outflow of water, and the valve C, may be lodged in to its position from top or bottom
of tap, in this way of making the said tap, the use of the stuffing box is dispensed
with and screwed on cap J, will take its place.
This tap as illustrated in Fig. I, and Fig. II, has a decided advantage over other,
in that :-
1, the greatest strength is given to the parts, which have to stand the most wear.
2, whatever condition it may be in, is sure to shut off the water, for the higher the
pressure, the tighter it will fit.
3, it is repairable at a trifling cost.
It is suitable for ordinary, as also for high pressure use, or for any liquid or steam,
it may be made of any suitable metal, or desired shape; the outlet may be direct
under the spindle A, or in some other direction preferable; E and D, may be rollers
or fixed studs, made in any shape, either in the cast, or secured afterwards, of which
studs or rollers may be two or more, or one continuous thread, the position of which
may be on the action in any other way, than shewn in the drawings; the valve C,

page_text: may be V, half ball, flat, or ☐ shaped, covered partly or wholly with leather washers,
or any other suitable material or without; the handle G, may be separately fixed to
spindle A, or cast in one piece, the same may be said of the spindle and the valve C;
the stuffing box H, may be filled or prepared with any material, to resist the upflow of
water; the plate or sheet I, to check the pressure of water, may be one or more and
of any shape according to requirement, or without; the groove, passage or cut F, if
necessary, may be placed in any part of the tap, in line of spindle A, and the outlet B;
the junction of the spindle A, with the valve C, may in some cases be necessary to be
linked, or some other arrangement, to act so, as to give the valve liberty, to fall easy
in to its resting place.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to bo performed, I declare that, what I now claim, is
The tap substantially as herein described and shown in the drawings
