Improvements in Hydrants.
I, ADAM SCHEID, of Harrison, County of Hudson and State of New Jersey,
U.S.A., Mechanical Engineer, my post office address being 212 Harrison Avenue,
Harrison, New Jersey, U.S.A., 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 to provide a hydrant, simple and durable in con-
struction, quick in operation and not liable to get out of order.
The invention consists in the improved hydrant, its piston operating mechanism,
its coupling, and the arrangement and combination of the various parts thereof,
substantially as will be hereinafter more fully described and finally embodied in the
clauses of the claims.
Referring to the accompanying drawings, in which like letters of reference
indicate corresponding parts in each of the several figures:
Fig. 1. is an elevation of my improved hydrant, part of it being shown in
section.
Fig. 2. illustrates a sectional view on line x Fig. 1. and in addition, the female
part of the coupling (detached).
Fig. 3. is an enlarged sectional view on line y. Fig. 1.
Fig. 4. is a detail view of the male part of the coupling and
Fig. 5. illustrates a modification of my improved hydrant.
In said drawings a, represents the hydrant body, provided with a top or
cap b. Through the centre of said top a bolt c, adapted to engage the threaded
opening of cross bar d, which again rests against the inner shoulder e, of the
body, as clearly shown in Fig. 1. of the drawing. (In Fig. 5. a modified form
of securing the top to the hydrant body is shown, whereby said top engages
with its threaded portion the internally threaded portion of the body a.) Below
said shoulder, and cast integral with the body, is arranged an internally threaded
tube, adapted to receive the threaded end of the male part f, of the coupling.
Said part is provided at its free end with two segmental flanges f¹, adapted to
be engaged by corresponding lugs f³, of the female part of the coupling.
The lower portion of the hydrant body a, is provided with a circular flange a', to
which is secured-by bolts a³, or in any desired manner-a metal plate a³, with inlet
connection a8.
Within the body a, is arranged the piston r, pivotally secured-at s-to the
piston rod o. The upper end of said piston rod is again pivotally connected-by
pin p-with one end of lever n.
The other end of said lever is firmly secured to shaft h, which has its bearings in
bushing k, and projecting lug 4, of the body.
The bushing k, is screwed into the internally threaded projection g, of the body,
and presses against the packing 1, which again rests against a collar or shoulder i,
on shaft h, thus providing a water tight bearing for said shaft.
The outer end of the shaft is provided with a squared portion, adapted to be.
engaged by the squared hole of operating crank m.
Above the piston r, and cast integral with the body a, are arranged guiding
blocks t, adapted to guide the said piston in its upward movement and also to
form with said piston (when the latter is moved upwards) channels t¹, through
which the inflowing water enters the hydrant. One of said guiding blocks is
provided with the air or water outlet u, arranged opposite a valve z, which again is
secured to stem 10. Said stem operates in bushing v, and is controlled by spiral
spring.

page_text: The bushing is provided with openings, as shown in Fig. 3. of the drawing.
In operating my improved hydrant, the crank m, is turned to the right (or left,
as the case may be) for about 90 degrees. The inlet a³, is thus opened, and the
water free to enter the hydrant through channel t¹.
The air hole or outlet u, is now closed by the piston.
When the crank m, is turned to its normal position, the inlet as, is closed and the
outlet u, opened.
If the pressure of the water, remaining in the hydrant, is not exceedingly large,
the water will run off through said outlet, without operating the valve z.
Should
the said pressure be sufficient to close said valve, the water will remain in the
hydrant; but the least pressure on the projecting end of the valve carrying stem w,
will open said valve, thus allowing the water to escape through openings ", and V,
as will be manifest.
In Fig. 5. of the drawings, I have shown a modification, in which the piston r, is
secured to the lower end of connecting rod o, the upper end of which is guided in
the top b, of the body a.
Said connecting rod is provided with a series of teeth o', engaging a pinion n',
secured to shaft h, the latter being operated by crank m.
In the lower portion of the body a, is arranged a bushing at, as with intermediate
chamber a provided with openings a.
The portions a' and as of the bushing serve as guides for the piston, the chamber a
with opening a as channel for the inflowing water, when the piston is moved
upwards.
I do no intend to limit myself to the construction, shown and described, as various
alterations can be made without changing the scope of my invention.
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 :-
1-In a hydrant, the combination with the body, the piston and piston
operating mechanism, of a top, a cross-bar arranged in said body and bearing
against an inner shoulder of the latter, and a bolt passing through said top and
engaging an internally threaded opening in said cross-bar, all said parts, substan-
tially as described and for the purposes set forth.
2 In a hydrant, the combination with the body, the piston and piston
operating mechanism, of a tube secured to said body, two segmental flanges,
arranged opposite each other and made integral with the outer end of said tube,
and a tube provided with corresponding lugs and adapted to engage said
segmental flanges, all said parts substantially as described and for the purposes
set forth.
3-In a hydrant, the combination with the body and piston, of a rod, pivotally
secured to said piston, a crank pivotally connected with the upper end of said
rod, and a shaft firmly secured to said crank and adapted to operate the latter,
all said parts, substantially as described and for the purposes set forth.
4-In a hydrant, the combination with the body and piston, of a rod pivotally
secured to said piston, a crank pivotally connected with the upper end of said
rod, a shaft carrying said crank, a projecting lug q made integral with the body
and adapted to serve as bearing for one end of the shaft, a bushing, arranged
opposite said lug and on the outside of the body and adapted to also serve as
bearing for said shaft, a flange or collar secured to said shaft, a suitable packing
arranged between said bushing and said flange, and a crank adjustably secured
to the outer end of said shaft, all said parts, substantially as described and for
the purposes set forth.
5 In a hydrant, the combination with the body and the water inlet, of two
guiding blocks secured to or made integral with said body, a piston adapted to
be operated in said body and be guided in its upward movement by said guiding
blocks, said blocks being also adapted to form with said piston, (when moved

page_text: upwards) channels to connect the water inlet with the hydrant, and means for
operating said piston, all said parts, substantially as described and for the
purposes set forth.
6 In a hydrant, the combination with the body and water inlet, of guiding
blocks, secured to or made integral with said body, a piston adapted to be
operated in said body and be guided in its upward movement by said guiding
blocks, said blocks being also adapted to form with said piston (when moved
upwards) connecting channels between the water inlets and the hydrant, means
for operating said piston and an automatically operated escape valve arranged
in one of said guiding blocks, all said parts, substantially as described and for
the purposes set forth.
'
7 In a hydrant, the combination with the body and piston, of a rod secured
to said piston and provided at or near its top with a toothed portion, a pinion
engaging said toothed portion, a shaft operating said pinion and a crank adjustably
secured to said shaft, all said parts substantially as described and for the
purposes set forth.
