ATOMIZING NOZZLE Filed Feb. 16. 1944 'acteristics of spraying.
Patented June 12, 1945 OFFICE vasias-is A'ronnzING NozzL'E Willianr L. Wilmes, John W. Baur-,and Eric Gustafsson, Chicago, Ill., asslgnors 'to Binks Manufacturing Company, Chicago,vlll.,a corporationof Delaware yApplication February 16, 1944, Serial No. 522,572 3 Claims. (Cl. 299-1201)A The present invention relates to nozzles and particularly the atomizing type of nozzles.
l Among the objects of the invention is to provide a novel nozzle that isV leak proof; one which is leak sealed to prevent the liquid reaching the threadsvof the nozzle and nozzle cap.
Another object of the invention is to provide a novel nozzle with a novel distributing means for the liquid to the tip member, and a novel tip member, either or both of which are readily replaceable by others of different capacity char- Other objects, advantages, capabilities, features' and the like are comprehended by the invention as will later appear and as are inherently possessed by the invention.
Referring to the drawing: Y
Figuresv l and 2 are longitudinal sectional views of nozzles constructed in accordance with the invention;
Figure 3 is an end view of the distributing mem- .ber or ring used in the nozzle;
Figure 4 is a 'sectional view taken in a plane represented by line 4-4 in Figure 3 of the drawing:
Figure 5 is an end view of a nozzle tip member;
. and
Figure 6 is a fragmentary sectional view, on an enlarged scale, of the nozzle tip member.
Referring more` in detail to the drawing the embodiments chosen to illustrate the invention are shown as comprising a body I or 2 each having a forward neck portion 3 suitably threaded for the reception of a nozzle cap 4, as shown. The body I has a rear externally threaded shank portion 5 provided with a passage 6 leading to a chamfber 1, and the bbds1 2. has a rear internally threaded shank portion 8 leading to a chamber 9. Forwardly of the chamber 1 or 9 is provided a shoulder III for the seating in sealing contact of a distributing member or ring II.
'I'hisdistributing ring I I, shown more particularly in Figures 2 and 3, is provided in its forward face with an annular channel I2, and in its rear portion with a plurality of ports I3 which are in communication with the channel I2 and the chamber 1 or 9. The forward face of the ring II is well within the neck 3 and rearwardly of the forward end of the neck 3.
Forwardly of the distributing ring I I is a nozzle tip member I4 which is circular and has a rear face abutting with a sealing contact with the forward face of the ring I I and with its rear portion fitting closely within the forward portion ofthe neck 3.as shown in Figures l and 2. The forwardy end of ythe tip member I4 has a reduced diameter portion I5 providing a shoulder I6 for abutment of an internal flange I1 of the cap 4. The portion I5 has an orice I8 communicating by way of a tapered passage po-rtion I9 with a chamber 20 in the rear part of the member I4.
In the rear face of the member I4 is provided one or more channels or slots 2| arranged secantly or tangentially to the chamber 20. 'I'he innerv ends of the channels 2i are open to the chamber 20 but their outer ends have curved portions 22' which end in the rear face of the member I4 and well within the outer periphery of the member I4. These channels 2i may be cut by a rotary cutter or the like 23'as shown in Figure 6. I
By having the outer ends of the channels 2i end radially within the periphery of the member I4 the rear face of the member I4 has a sealing contact with the forward face of the ring II radially beyond the radially outer ends of the slots or channels 2| Q thus preventing passage of liquid from the interior of the nozzle parts to the neck 3 and hence to the threads of the neck 3 and cap 4. In addition, the outer peripheries of the member I4 and the ring II fit. with a seal- -ing` contact within the neck 3 further insuring prevention of passage of liquid to the threads of the neck 9 and cap 4. Also, by reason of the ringII having a sealing contact with the shoulder I0, there is a vfurther prevention of passage ofnliquid to the neck 3 and hence to the `threads of neck 3 and cap 4.
In operation,.the liquid passes through the chambers 6 and 1 (Figure l) or chamber 9 (Figure 2) to and through the ports I3 to the channel I2 to be distributed to the channels 2| whence the liquid is projected to produce a whirl in the chamber 2li and to pass with a whirling action to and through the orifice I8.
When spraying different liquids or at different pressures, whereby different sizes of oriices and diierent sizes of channels 2l would be used, the tip member I4 may be readily replacd by another having e. different size orifice and a different size channel to meet the different conditions of spraying. Likewise the rings II may be as readily interchangeably used with different sizes of ports I9 and channels I2.
While we have herein described and upon the drawing shown illustrative embodiments of the inventiomit is to be understood that the invention is not limited thereto but comprehends other constructions. details, arrangements of parts, features. and the like without departing from the spirit of the invention.
