Faiver, Buena Park, Calif., assigner to Diffuser Corporation, Fullerton, Calif., a cor poration of California Application July 22, 1936, Serial No. 91,862 1 Claim. (Cl. 299-87) This invention relates to diiiusers. 'I‘he general object of the invention is to pro vide an improved dilfuser by means of which var ious chemicals can be projected into a space to be 5f.: treated. Another object of the invention is to provide a novel nozzle for a diffuser. An additional object of the invention is to pro vide a novel blow-off valve for a diiîuser. 10 Another object of the invention is to provide a diiîuser including a novel container having novel vessel supporting members therein. Another object of the invention is to provide a novel mechanism for controlling the amount of 15 chemical discharged by a diffuser. Other objects and the advantages of the in vention will be apparent from the following de scription taken in connection with the accom » panying drawings, wherein: 20 Fig. 1 is a. top plan View of a diifuser embodying the features of my invention; Fig. 2 is a central, sectional view taken on line 2-2 of Fig. 1; Fig. 3 is a fragmentary, sectional View taken on 25 line 3-3 of Fig. 2; Fig. 4 is an enlarged, fragmentary, sectional view showing the discharge nozzle and associated parts; 30 Fig. 5 is a section taken on line 5-5 of Fig. 4; Fig. 6 is an enlarged, fragmentary side eleva tion showing the diffuser; Fig. 7 is a central, sectional view showing the blow-olf member; and Fig. 8 is a side elevation of the sleeve. Referring to the drawings by reference charac ters I have shown my invention as embodied in a diiiuser which is indicated generally at I0. As shown the diffuser includes an outer container II which may be made of metal or other suitable 40 material and which may be provided with a side seam I2 and with a bottom I3 secured thereto. The bottom may be provided with bosses I4 upon which the container is supported. The container is shown as provided with a bail I4' and with a 45 closure I5 which has a sliding ñt with the con tainer so that the closure is removable. The container II is provided with a plurality of viewing apertures I6 and with a lining I'I which may be made of “Cellophane” or similar 50 material. Within the container I arrange a ñxed shelf I8 which includes a ílange I9 and supporting ears 20 which may be riveted as at 2I to the container and above the shelf I8 I provide a sec ond shelf 22 which includes a bottom 23 having 55 sides which are pivoted as at 24 so that the shelf may swing to a position parallel to the shelf I8. The shelves I8 and 22 areemployed to support vessels which hold chemicals. The shelf I8 is in tended to support a relatively long chemical hold ing vessel while the shelf 22 when lowered to the dotted line position in Fig. 2 serves to hold a shorter vessel. As shown in the drawings the shelf I8 is employed to hold the chemical holding Vessel 25 which has a threaded cap 25 thereon. 'I'his cap is provided with a central aperture 21. 10 'I‘he upper end of the vessel 25 projects through an aperture 28 in the closure I5. Disposed within the container I I I show a steam generating device indicated generally at 29. As shown this device includes a receptacle 30 which 15 may be made of glass and which has a metallic lid 3| mounted thereon. The lid is provided with suitable apertures in which grommets 32 are mounted. These grommets 32 are preferably made of vulcanized liber, or similar insulating 20 material and through the grommets electrodes 33 extend. 'I'he electrodes 33 include terminal por tions 34 adapted to be disposed below the normal water level 35 in the receptacle 30. Mounted on the receptacle I show a discharge l25 tube 36 which includes a lower iiange 31 which serves to hold the tube in place on the lid 3 I. The tube passes through a grommet 38 on the closure I5 and is provided with a circumferentially ex tending groove 39 which is intersected by aper 30 tures 40 which alford communication between the interior of the tube and the groove. Mounted within the tube 36 I provide a blow-off valve mem ber 4I which threadedly engages the interior of the tube and. which includes a lower aperture 35 42 and a hexagonal valve member 43 which slid ably fits in a cylindrical aperture 44. The aper ture 44 communicates with an outlet 45. When the pressure within the container 29 be comes excessive the valve member 43 is moved 40 from its seat to relieve this excessive pressure. Mounted upon the tube 36 I show a sleeve 46. This sleeve is held in place by a ñange 4l on the valve member 4I and the sleeve has an aperture in which a nozzle 48 is mounted. This nozzle 48 45 communicates With the groove 39 previously men tioned. The construction is such that steam gen erated in the container 29 passes out through the nozzle 48 and through a discharge member-49 on the end of the nozzle. Mounted within the 50 nozzle I show an injector tube 50 which tube passes through the aperture 2l previously men tioned and extends to a location near the bottom of the chemical holding vessel 25. The injector tube 50 passes through the wall of the nozzle 48 as 55 2,122,639 at 5| Where a leak-tight joint is provided and ex tends to a. location 52 at the end of the discharge member 49. The length of the downwardly ex tending portion of the injector tube Will be varied to suit the conditions and when long vessels are employed as shown in Fig. 2 the tube will 'be of the length shown. If shorter vessels are em` ployed then the length of the.; lower portion of the tube A50 will _be _correspondingly decreased. 10 'I'he nozzle 48 adjacent to the discharge mem ber 49 is engaged by a plurality of screws 53 _ shown as three in number which are threaded in> apertures in the nozzle and which engage the end of the injector tube. By releasing two of the 15 screws and tightening the third -screw the posi tion of the injector tube 50 relative 'to the outlet of the end 52 may be shifted thus shifting the eccentricity-of the tube 50 with respect 'to the noz- 1 zle so that the injection effect may be varied. With my invention when the steam .generating 20 apparatus is operated the heat _generated therein passes through they Walls of the :generating ccn tainer thus heating the chemicalA holding vessel, My device is adapted for use with various types of chemicals and may be used for treating various spaces in order to destroy flies, mosquitoes, etc. My device may be employed with solutions con taining pyrethrum or other materials as desired. From the foregoing description it will be ap parent that I have invented a novel diñuser which canbeeconomically manufactured _and which is highly eñicient linuse. f ." f ¿fr l; l" ' yI-Iaving thus described my invention‘I claim: ‘generating device, said steam generating device including a receptacle, a lid on said receptacle, a discharge tube on` said lid, a sleeve removably `mounted-on said tube, a closure member threaded 15 Within saidtube 'and having a flange thereon en~ gaging said sleeve to normally prevent removal of 'the sleeve, said tube having apertures there» through, said sleeve having a nozzle therein corn municating with said apertures, an injector tube 20 extending into , said vessel,l said injector tube piercing said nozzle intermediate the .length of the fnozzle,;said injector extending yinto andalong also the steam passing through the nozzle warms the interior of said nozzle,. said nozzle having an- the latter thus -causing the material Adrawn into outlet, the diameter of said outlet being .greater than -theiexterior- diameter of said injector tube. the injector to vbe heated.
