Patented Oct. 8, 1929 UNITED STATES PATENT OFFICE,
Lns'rnn Wm, or NEW nocnnzm, mew Yonx, assrenon 'ro comm, A ooaromrron or NEW .umsmr rim 34mm SPRAY NOZZLE This invention relates to a nozzle. It is' especially adapted to nozzles that may be used,
or spraying tarvia or other b1- tuminous material ,upon streets or highwa s. These nozzles are of such a type that the liquid material is injected into the cylindrical bowl of the nozzle along a tangential line and makes its way to the outlet that is located alon the axis of the cylinder in such a manner tiiat the material 1s rojected in the desired direction. In noz es of this type it is desirable to have the outlet of a conical shape flaring outwardly so that the liquidmaterial will be sprayed in the shape of a cone. p
The invention will be understood from the description in connection with the accompanyingdrawings, in which Fig. 1 is a plan view of the devlce w1th the cover removed Fig. 2 is a section Fig. 1;
Fig. 3 is a erspective view of a detail; Figs. 4 and 5 are sections through outlets of different sizes; Fig. 6 is a section through a modification;
along the line d-a of Fig. 7 is a section along the line bb,of Fig. 6.
- In the drawin s, reference character 1 indicates the cylin ricall shaped bowl of the nozzle which merges a ong its lower edge into the conical portion 2. The cylindrical portion is threaded along its upper edge on the inside as shown at 3 and a threaded cover 4 fits therein. The conical portion 2 is threaded on the inside as shown at 5 and a threaded plug 6 screws into the same. This threaded plugs is provided with a conical outlet 7. A screw threaded projection 9 on the side of the nozzle enables the same to be screwed into a supply pipe and a tangentialinlet 10 extends through this plug 9 into the bowl 1.
Plugs 6 and 6" provided with conically shaped outlets 7' and 7" as shown in Figs 4 and 5 may be screwed into the conical por-- may be inserted in this bowl and turned until its edge 12 overlaps the side 13 ofthe inlet 10 to the desired extent thereby artially closing this inlet. The edge" 12 will preferably be bent inwardly alon its upper portion as shown at 14 so as to divert the liquid slightly in a downward direction as it whirls around by centrifugal force along the inner surface of the bowl 1 and thus the liquid will be caused to descend in spiral paths to the outlet 7. The spring sheet 11 is normall held in position b the natural outward sprlnging of the curve sheet. The friction of cap against .the curved sheet may also be utilized to hold the sheet in place, or a set screw can be passed through the cover 4 or bowl 1 to hold the sheet in place.
In the modification shown in Figs. 6 and 7 instead of having a separate sheet of metal 11 as shown in Fig. 3, the cover 4 is provided with an annular depending flange 16 which has holes 17 of different sizes therein. One edge of these holes is beveled as shown at 18 so as not to interfere with the entry of the liquid into the bowl 1, and by adjusting the cap 4 to different positions the inlet 10 can be shut off or restricted to any desired extent by the material that lies at the edge of any one of the holes 17 I claim:
1. In a spray nozzle comprisin a cylindrical bowl, a tangential inlet an an axial conical outlet, and an adjustable bafile inside said bowl adapted to vary the size of said inlet.
2. In a spray nozzle comprisin a cylindrical bowl, a tangential inlet am? an axial conical outlet, and adjustably curved means inside said bowl utilizing centrifugal force for urging incomingmaterial in a direction away from the inlet.
3. In a spray nozzle comprising a cylindrical bowl, a tangential inlet and an axial conical outlet, and an adjustable curved sheet, havin a bent upper corner, for varying the size 0? said inlet, said outlet and bent upper corner being oppositely disposed.
Ina spray nozzle comprising a cylindrical bowl, a tangential inlet and an axial conical outlet, and an adjustable curved sheet spring-held in position for varying the size of said inlet and shaped to direct the flow of material to the oppositely disposed outlet of said nozzle. 5. In a. spray nozzle comprisin a. oylin-' drical bowl, a tangential inlet an an axial conical outlet, and an adjustable curved sheet spring-held in position for varying the size of said inlet, an upper corner of said sheet bein turned inwardly and oppositely dispose from said outlet.
In testimony whereof I afiix my signature.
