MEANS FOR-GRINDING TRIPLE VALVES.
Specification of Letters Patent.
Patented July 27, 190O
Application filed March 25, 1908. Serial No. 423,241.
To all.w om it may concern:
. Be it known that I, EZRA E. INNIS, a citi-
zen of the United States, residing at Child-
ress, in the county of Childress and State
5 of Texas, have invented new and useful Im-
provements in Means for Grinding Triple.
.Valves, of which the following is a specifica-
This invention relates to means for grind-
10 ing triple valves, including the valves
proper 'and their bodies or casings, so that
each valve and its casing may be accurately
ground for a close and true fitting of their
15 They object of the invention is to provide
sinip and effective means whereby such
valves may be rapidly and economically
In the accompanying drawing :-Figure 1
20 is a: side elevation of the apparatus with a
valve supported in position to be ground.
Fig. 2 is a detail view of the upper end of
the support for the valve casing. Fig. 3 is a
side view of .the valve, showing the oper-
25 ating rod connected therewith. Fig. 4 is a-
longitudinal section through the valve and
its casing, with the operating rod coupled
to the valve. Fig. 5 is a detail view of the
upper end of the guide standard. Fig. 6 is
30 an end view of the drive shaft and supports.
In order, to clearly indicate the mode of
use of my invention, I have shown in the
drawing an ordinary form of triple valve A
and triple valve casing B. The stein a of
35 the valve is provided at one end with the
usual threaded portion a' for the connection
of the piston head of the valve therewith.
The casing B is formed at one end with a
chamber b in which the said piston head
40 operates, and is provided at its opposite end
with the apertured bolting flange b' and
. threaded coupling projection b2
c is the valvelhushing or seat arranged
within the casing B and (.( the spring car-
45 tied by the valve for holding its suriiaees il
close engagement with tl oa(ting surfaes
of the seat.
The purpose of my invention is to pro-
vide a simple and etleetiye constriction of
50 imechanismii whlerebv the valve A may be re-
ciprocated il its asingI B. so that. the sir-
flces of the valve and its seat will be aea-
rittelv ground by friction for a close and
tru fitting( of 111('th (Oir ouet surfaces. to-
55 ,ether. 1o this (111d I piovide means for
Supporting the Vlve eatiigi and means for
reciprocating the valve therein, such recip-
rocating means being guided to operate in
a true path so as to insure an accuracy of
movement of the valve for a uniform grind- 60
ing of the contacting surfaces.
In the drawing I have shown one means
for carrying my invention into practical
effect, and therein I employ a standard or
supporting member 1 for the valve casing 65
B, which standard or supporting member
is provided at its upper end with an opening
2 to receive the coupling projection b of
the casing, and is also provided around said
opening with opemngs 3 for the passage of 70
bolts 4, whereby the casing is fastened there-
to. These bolts pass through the usual bolt
openings in the flange b', and secure the cas-
ing to the support 1 so that the chambered
end b of the casing projects outward. 75
Arranged at a suitable distance from the
support 1 is a pair of standards 5, between
which extends a drive shaft 0 journaled in
suitable bearings therein. On the shaft be-
tween the members is a pulley 7 by which 80
power may be applied thereto from any suit-
able source. One end of the shaft projects
beyond the adjacent standard and is formed
to provide a crank 8.
A pitman .9 is connected at its outer end 85
with the crank 8 and is' pivotally attached
at its inner end, as at 10, to the outer or rear
end of an operating. rod 11, which rod is
arranged to reciprocate through a guide
opening 12 in the upper end of a stald(lard 90
or suitable guide member 13. The inner or
forward end of the rod 11 is formed with
a head 14 to bear against the threaded por-
tion a' of the triple valve stem, to which it
is connected by a coupling sleeve 15. The 95
said coupling sleeve is internally threaded at
its outerportion to engage the part a' and
is provided with a flange 16 to engage the
rear surface of the head 14, which flange em-
braces the rod 11 but is not secured thereto, 100
thus enabling the sleeve to be rotated in one
di re(t on or the other to couple the rod with
0r iiuroiUple it from the valve stem.
In the operation of the device, the valve
i1 secr'.led in the manner shown to the sup- 105
porting standard or bracket 1 and the valve
conneCted by the coupling 3 with the rod 11,
after which the shaft ( is set in operation,
by which the rod 11, through the pitman :)
and crank' 8, will be reciprocated back and 110
forth and correspondingly reciprocate the
valve A in its casing B, by which means the
Here’s what’s next.
