DON B. ADAMS, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO ROMULUS
NEHIEMIAII GRAHAM, OF FORT WORTH, TEXAS.
NOZZLE.
SPECIFICATION forming part of Letters Patent No. 578,706, dated March 16, 1897.
Application filed May 4, 1896, Serial No. 590,202. (No model.)To all whom, it Lay con tcer:
Be it known that I, DoN B. ADAMS, a resi-
dent of Chicago, in the county of Cook and
State of Illinois, have invented certain new
5 and useful Improvementsin Nozzles; and Ido
hereby declare the following to be a full, clear,
and exact description of the invention, such
as will enable others skilled in the art to which
it pertains to make and use the same.
to The invention relates to nozzles, and has
for its object to increase the capacity and
efficiency of such devices and insure cer-
tainty of action and convenience in adjust-
ment and operation; and the invention con-
15 sists in the construction hereinafter described
and particularly pointed out.
In the accompanying drawings, Figure 1 is
an isometric view of a nozzle. Fig. 2 is a
front elevation. Fig. 3 is a longitudinal sec-
20 tion. Fig. 4 is a side elevation of a pipe-
section. Figs. 5 to 9, inclusive, are side ele-
vations of details. Fig. 10 is a plan of a
nozzle having but three discharge-openings,
and Fig. 11 is a section of a plate online 1111
25 of Fig. 10.
Numeral 1 denotes a short pipe-section
having a frusto-conical bore and adapted to
be screwed upon another section or length of
pipe. The pipe-section 1 is provided with
30 external screw-threads 2, situated near its
smaller end, but separated therefrom by a
smooth portion 3. Within said part 3 is a
groove or recess 4 to receive rubber or other
packing. The inner wall 5 of said recess ex-
35 tends beyond the rest of the pipe-section and
is adapted to enter and fit a countersunk re-
cess 6 in a plate 7 and surrounding a pas-
sage 8 through said plate. This plate is held
to the pipe so that its countersunk recess 6
40 fits the tubular wall 5, and it is also held
against the rubber packing by a flanged ring
9, screwed onto a plate 10, having a socket or
cylinder, whereby it is screwed onto the
threaded part 2 of the pipe-section.
45 11 is an annular packing seated in suitable
grooves in plate 7 and in a circular plate 10.
Plate 7 rotates between the flanged ring 9
and said plate 10 about a pivot-screw 12.
This screw is stepped in the top of the plate
50 10 at its center and at one side of the eccen-trick opening 8 therein. Said plate 10 also
has an eccentric screw-threaded cylinder or
socket, the bore of which is continuous with
opening 8 and is adapted to be screwed at 2
upon the pipe-section 1. Said screw 12 ex- 55
tends through the plate 7 and has a smooth foot
turning in a socket in the center of plate 10.
15' indicates screws to hold the milled ring
13 in fixed relation to the rotating plate 7.
The flange of the ring 13 is milled to fit it 60
for manipulating the plate 7. Said plate has
several openings, of which that marked 8
is one. 14, 15, and 16 denote others. Each
opening is surrounded by a countersunk re-
cess 6. The plate is rotated to bring any one 65
of these openings to register with the pipe-
conduit, as desired, the openings in the plate
being of different sizes to provide for throw-
ing different-sized streams.
The joint between the ring 10 and the pipe 70
1 is closed by a stuffing-box 14', which, to-
gether with the ring-packing 11 and the pack-
ing in recess 4, effectually prevents leaking.
The stuffing-box and the packing-ring stop
the escape of air and so cooperate with the 75
packing in recess 4 to prevent any fluid es-
cape between the pipe and plate 7. Said
plate may be provided with imperforate por-
tion 16' large enough to entirely close the
pipe when desired, recesses 6 being omitted So
from plate 7, as indicated in Fig. 11.
17 denotes a spring locking-pin movable
through a stud 18 and through an extension
19 of the milled flange of the ring 13 and adapt-
ed to enter a hole in said extension, with the 85
effect to lock the ring 13 and flanged ring 9
together.
20 is a stop to prevent the entire withdrawal
of the pin from its bearings. The spring 17
normally bears against stud 18 and against a 90
collar 21 and tends to push the pin outward
or to the position shown. 22 is a similar lock-
ing-pin having bearings in a housing 23, at-
tached to pipe 1 and adapted when engaged
with a hole 24 in the stuffing-box to hold the 95
pipe and sleeved ring from rotation with re-
spect to each other. The pipe-section being
firmly held by its connections with the main
lengths of pipe and the pin 22 engaged with
one of the holes 24, the milled ring and plate ioo
