JEAN MARIE BAURENS, JR., OF PORT ARTHUR, TEXAS.
VALVE-OPERATING MECHANISM.Specification of Letters Patent. Patented Sept. 10, 1918.
Application filed June 6, 1917. Serial No. 173,210.To all whom it may concern:
Be it known that I, JEAN MARE BAURENS,
Jr., a citizen of the United States, residing
at Port Arthur, in the county of Jefferson
5 and State of Texas, have invented new and
useful Improvements in Valve-Operating
Mechanism, of which the following is a
specification.
My invention relates. to valve operating
10 mechanism and has for its primary object
to provide a .simple and efficient means for
operating a valve at a distance.
A further object of my invention is to
provide a valve operating mechanism which
15 can be easily attached to the valve stem of
an ordinary valve.
A further object of the invention is to
produce a guide revolubly mounted on the
hub of a chain carrying sprocket wheel
20 which is secured to the stem of the valve to
be operated, said guide being in the nature
of a casting and having a flanged hood at
one of its ends arranged over the sprocket
wheel for retaining the chain in engagement
25 therewith and having its other end weighted
and provided with a yoke through which the
leads of the chain pass.
With these and other objects in view
which will be hereinafter fully described
30 and particularly pointed out in the claim,
the invention consists in the novel construc-
tion and arrangement of parts illustrated in
the accompanying drawings forming a part
of this specification, in which:-
35 Figure 1 is a sectional side elevation of a
valve to which an operating mechanism em-
bodying my invention is attached.
Fig. 2 is a front elevation of the same.
Like characters of reference indicate like
40 parts in the various views.
In the drawings 1 designates a valve body.
The valve body has a passage 2 leading
therethrough, and a partition 3 extends
across said passage 2 and has an aperture
45 4 therein which connects portions of the
passage lying above and below the partition.
That portion of the partition 3 which has
the aperture 4 therein lies parallel to the
passage and has a valve seat 5 formed about
50 the aperture 4. An apertured boss 6 is
formed on the valve body in axial alinement
with the valve seat 5, and a flanged sleeve
7 is secured on said boss by means of a nut 8,
which is screw threaded upon the boss 6,
55 clamping the flange of the sleeve against the
end o the boss.. The aperture of the sleeve7 is disposed in axial alinement with the
valve seat 5 and has screw threads 9 formed
at the inner end thereof. A valve stem 10 is
screw threaded into the screw threads 9, and 60
has a valve 11, mounted at its inner end,
which is adapted to engage the valve seat 5
when the stem is screwed to its inner posi-
tion and to close the valve thereby. The
stem 10 extends outwardly from the sleeve 7, 65
the sleeve 7 having a packing nut 12 screw
threaded upon its outer end to prevent leak-
age between the sleeve and valve stem. The
stem 10 is formed angularly in cross section
near its outer end, as designated at 13, the 70
inner end of said angular portion having
an outwardly facing shoulder 13', and the
extreme end thereof is screw threaded as
designated at 14. The above described con-
struction is well known to those skilled in 75
the art and needs no further description for
the present purposes except to say that all
valves of this construction are usually pro-
vided with a hand wheel which engages the
angular portion 13 and is secured thereon by 80
means of a nut screw threaded upon the
screw threads 14.
15 designates a sprocket wheel which is
provided with a centrally disposed angular
aperture which is adapted to fit closely over 85
the angular portion 13, the inner surface of
the web 16 of the wheel abutting the shoul-
der 13'. A hub 17 projects from the outer
face of the web, the combined thicknesses of
the web and the hub being approximately 90
equal to the length of the angular portion 13.
Sprocket teeth 18 are formed upon the pe-
riphery of the wheel 15, and a circumfer-
ential flange 19 is formed upon said wheel
upon each side of the teeth 18, said flanges 95
being spaced from the teeth 18 so that a
chain 20 may be trained over said sprocket
wheel to engage the teeth of the same. 21
designates a guide member which is rota-
tably mounted upon the hub 17 by an offset 100
apertured boss 22. The guide is in the
nature of a casting, being constructed from
a single piece of material. Arms 23 are
formed upon the outer face of the boss of
the guide member 21 and extend laterally, 1o5
closely adjacent the outer flange 19, and
support a transverse flange or hood 24, said
transverse flange extending around the up-
per portion of the wheel 15 and lying closely
adjacent the peripheries of the flanges 19, 110
and the chain 20 is completely inclosed as it
passes over the upper portion of the wheel1,278,423.
