fact that the base of the barrel is provided
with a shoulder for holding the cup rings
and valve cups against losing.off in opera-
tion, as there is no nut to become loose as is
5 true of the plungers now in common use
and attention is called to the beveled projec-
tions for the purpose of engaging the crown
of the lower or standing valve, so that should
the couplings of the plunger become loose
10 the said plunger may be jammed down onto
the crown of the standing valve and said
couplings be tightened by turning the
plunger by means of a rod which screws onto
the crown of the plunger, these flanges serv-
15 ing to hold the lower portion of the plunger
stationary while. the couplings are being
tightened. It is to be further noted that the
rib on the valve seat contacts on one side
with the bushing forming ground joints and
20 on the other side it contacts with the cage
or crown which is screwed down on the bush-
ing forming another close fitting joint which
when all the other points are properly con-
nected forms my complete and improved
25 plunger.
In the figure the numeral 14 designates
the top portion of the standing valve into
which an iron rod 15 is screwed. This rod
carries an enlarged head 16 upon its upper
30 end. In this form of plunger the bushing
is elongated and the rod 15 extends up in-
side thereof as shown in the drawing. This
bushing is provided with a nut 17 which is
screwed up inside of the bushing. This nut
35 is provided with an opening 18 through
which the rod 15 passes. .fThis opening is
much larger in diameter than the diameter
of the rod but is smaller in diameter than
the diameter of the head of the rod and
40 thus in raising the plunger the head of the
rod 15 is engaged by the nut 17 and the
plunger and standing valve are held to-
gether in withdrawing them irrespective. of
the condition of the intermediate parts, the
45 means for engaging the head of rod 15 be-
ing independent of the barrel of the plunger.
The nut is held against turning in the bush-
ing by a set screw 19.
While I have shown this particular de-
50 sign and described this special method of
operation. I desire it to be understood that
the invention is not limited either to this
particular form or specific construction but
may be varied so long as the principle is not
55 departed from.
What I claim is:-
1. In a plunger, the combination with a
barrel having a shouldered base integral
therewith, said plunger being provided, at
60 its lower extremity, with downwardly pro-
jecting outwardly tapering flanges of abushing secured upon the extremity thereof,
a threaded nut secured within the inner
walls of said bushing upon the thread
walls thereof, means for holding said i
in its proper place; a rod operating loosely
within said barrel and through an aperture
in said nut, said rod being secured to a
standing valve beneath and being provided
with a head at its upper. extremity for se- 70
curing engagement with said nut; said rod
being so disposed as to secure said standing
valve to the bushing of the plunger.
2. In a plunger, the combination with a
barrel having a shouldered base integral 75
therewith, said barrel being provided on its
lower end, with downwardly extending and
outwardly tapering flanges; of a-bushing se-
cured upon the other end, of said barrel; an
outwardly threaded nut secured within the 80
inner wall of said bushing upon the threaded
wall thereof ; a set-screw passing through
the wall of said bushing and into the said
nut for holding the same securely in place;
a rod operating loosely within said plunger .85
and through an aperture in said nut, said
rod being secured to a standing- valve be-
neath and being provided with a head at its'
upper extremity for securing engagement
with said nut; and being so disposed as to- 90
secure said standing valve to said plunger;
a crown carried on one. extremity of the said
bushing; a reversible valve seat carried with-
in the said crown and a ball ti close said
valve seat, substantially as described. 95
3. In a plunger the combination with a
barrel having a shouldered base integral
therewith, said barrel carrying at its lower
end downwardly projecting flanges;. of a
bushing secured to the other end of'said bar- 100
rel; a' nut secured upon the inner wall of
said bushing; a means passing through the
wall of said bushing and engaging with said
nut for holding the same in place; a rod
operating loosely within said plunger and 105
through an aperture in said nut, said rod
being secured to a standing valve beneath and
being prove -___th a means at its upper ex-
tremity for securing engagement with said
nut, and being so disposed as to secure said 110
standing valve to said plunger; a crown car-
vied on one extremity of said hushing; a
reversible valve seat .carried within said
crown and means to close said valve.
In testimony whereof, I have signed my 115
name to this specification in the presence of
two subscribing witnesses.
