engendered friction will cause any imperfec-
tions in the engaging surfaces of the valve
and casing to be worn smooth and to an ac-
curately fitting condition. To facilitate
5 this operation it will be understood, of
course, that a grinding medium of grit or
any other suitable material may be employed
between the 'surfaces of the parts, but a
simple reduction of the surfaces to a close
10 fitting engagement by ordinary frictional
contact is preferred. As the rod 11 is accu-
rately guided in a true path by the guide
niember 13 it will be apparent that the valve
A will be correspondingly reciprocated, so
15 that the valve cannot move out of its normal
path and cause uneven wear. Any number
of valve casing supporting devices and valve
reciprocatig devices may be employed for
operation from one -mid the same shaft (
20 to enable a plurality of triple valves 'to be
ground at a time from the same source of
power, but the present disclosure is sufficient
to illustrate the principle of my invention,
from which the advantages resulting from
25 my mode of grinding valves of this class
will be readily appreciated by those versed
in the art.
Having thus fully described the invention,
what is claimed as new is:
30 An apparatus for grinding triple valves
comprising a vertical standard for horizon-
tally supporting the valve casing, said stand-
ard being provided with an opening for thereception of a projection on one end of the
valve body, and having a series of holes ex- 36
tending partially around said opening for
the passage of bolts to secure a flange at
said end of the valve body to said standard,
bearing standards, a crank shaft horizon-
tally supported in said bearing standards, a 40
reciprocating rod having an annular head or
shoulder at one end thereof, a coupling
sleeve fitted to slide and rotate on the headed
end of the rod, said sleeve having at one end
a bore for the passage of the rod and at its 45
other end an internally threaded portion for
engagement with the threaded end of the
valve stem, and provided between said bore
and threaded portions with a chamber of
greater diameter than the bore to receive 50
said annular shoulder, a pi tman connecting
the threaded end of the rod with the crank
shaft, whereby said rod is reciprocated in a
horizontal plane, and a guide standard dis-
posed between the valve supporting standard 55
and shaft and provided with an opening
through which the rod reciprocates, whereby
said rod will be guided in its reciprocatory
movements in a straight path to correspond-
ingly reciprocate the valve within its casing. 60
In testimony whereof I affix my signature
in presence of two witnesses.
