BOILER ATTACHMENT.Specification of Letters Patent.
Patented May 31, 1910.
Application filed December 9, 1909. Serial No. 532,292.
To all whom it may concern:
Be it known that we, Gm M. Mowrus and
JOHN H. WATKINS, citizens of the United
States, residing at Palestine, in the county
5 of Anderson and State of Texas, have in-
vented certain new and useful Improvements
in Boiler Attachments, of which the follow-
ing is a specification.
Our invention relates to an improvement
10 in boiler attachments and particularly to an
apparatus for controlling the operation of
the boiler feed pump or injector.
The. object of the invention is to pro-
vide an apparatus suitably connected to the
15 boiler in place of the usual water column
comprising a float having connection with
a cut-off in the steam supply pipe whereby
the water in the boiler is maintained within
the " safety " limit as long as there is a
20 supply of water.
Finally the object of the invention is to
provide means of the character described
that will be strong, durable, efficient, and
easy of operation, simple and comparatively
25 inexpensive to construct, and also in which
the several parts will not be likely to get out
of working order.
With the above and other objects in view,
the invention has relation to certain novel
30 features of construction and operation, an
example of which is described in this speci-
fication and illustrated in the accompany-
ing drawings, wherein:
Figure 1. is an end elevation of a boiler
35 showing the apparatus connected thereto.
Fig. 2. is a vertical sectional view of the at-
tachment, and Fig. 3. is a transverse verti-
cal section on the line a-a of Fig. 2.
In the drawings the numeral 1 designates
40 a boiler and 2, the steam dome. At one side
of the boiler our attachment is positioned
so that its longitudinal center will substan-
tially aline with the water line of the boiler.
The attachment comprises a vertical float
45 chamber 3 having at its central portion a
laterally extending and converging neck 4 to
which a cylindrical valve casing 5 is suit-
ably secured. At its upper side the valve+
casing has connection by a pipe 6 with the1
50 steam dome 2, while from its under side a1
pipe 7 extends to the injector or feed pump
of the boiler. Through these pipes and the
valve casing, steam passes from the steamdome. A pipe 8 passes from the top of the
boiler to the upper end of the chamber 3. 55
At its lower end the chamber has connection
by a coupling 9 with the feed water pipe
10. It is obvious that the water in the
chamber 3 will rise or fall to the same level
as the water in the boiler, the pipe 8 permit- 60
ting steam to pass from the boiler into the
chamber over the water therein.
By observing Fig. 2 it will be noted that
the chamber 3 and valve casing 5 are sepa-
rated by a wall 11. A longitudinal valve 65
rod passing through suitable packings ex-
tends into the neck 4 a short distance be-
yond the wall 11 and at its opposite end
projects from the valve casing. Within the
neck 4 a bell-crank lever 13 is pivoted to 70
an ear 14 extending from the wall 11. On
the outer end of the lever 13 a suitable float
15 is secured, while the inner end of the lever
engages the valve rod 12 between adj ustment
nuts 16. From this it is obvious that as the 75
water level in the chamber varies, the float
will swing the lever to reciprocate the valve
rod 12. That part of the valve rod within
the valve casing is screw threaded as indi-
cated at 17 in Fig. 2. This portion extends 80
through an ear 18 projecting up from a slide
valve 19 working on a horizontal web 20
extending across the valve chamber and
separating the upper and lower portion.
This web is provided with ports 21 with 85
which ports 22 in the slide valve register.
It is to be understood that these ports may
be of any suitable shape as for instance
round, triangular or elongated all of which
are common in the art. 90
It is obvious that when the water falls the
float will swing the arm 13 down which will
slide the valve 19 through the agency of
the rod 12 into such position as to register
the ports 22 with the ports 21 and permit 95
the passage of steam from the pipe 6 or
the upper part of the valve casing to the
lower part of the valve casing and by way
of the pipe 7 to the injector or feed pump
(not shown) thereby causing the same to 100
operate and supply water to the boiler. As
the water rises in the boiler the float 15 will
be carried upward, the lever swung and the
valve moved so that the ports will be out
of alinement and the supply of steam pass- 105
ing through the valve casing cut off which960,229.
