Description

and connected to the head 2 of the body l by screw bolts 29 or other fastening means. The connection 28, as in the case of a manifold connection, contains the usual throttle or butteriiy valve 30.

Extending upwardly into the cap 25 is an annular wall 3l forming part of the head 2 and said Wall has air intake openings 32 adapted for admitting air into the well 5 and the chamber formed by the Wall seat 3 of thc he annular shutter 33 is inverted channel shaped in cross section and is Weighted or balanced, as at 34to normally close the air intake openings 32 of the Wall e annular shutter may be raised by a reduction of atmospheric pressure in the upper part of the cap 25, particularly between the Wall 31 and the annular Wall of said cap, and impetus may be imparted thereto by'a member to be hereinafter reicrred to.

side Walls thereof provided With openings 36. The top of the regulating member 35 has a concentric outlet sleeve 37 directly above the sprayY nozzle 22 and the inner Walls of this outletv sleeve are helically grooved to coperatie With the tangentially disposed grooves 24 of the spray nozzle 22 in imparting a whirling movement to air and liquid when emitted by the sleeve 37'.

he upper end ofthe regulating member 35 normally rests on the spray nozzle 22 and coperates With said nozzle in providing a restriction which may increased in area ber and fin proxsaid may be elevated to place the openings 36 thereof in communication with the Well 5. The upper large end of the foraminous member 39 corresponds in diameter to the connection 28 and `iS Supresaca@ ported on the cap 25 at the edges of the opening 2?'. The perforations or apertures of the member 39 may gradually decrease 1n diameter from the small end of the memhas a screwthreaded portion 42 in engagement with a hanger 43 so that rotation of the rod 4-0 Will raise and lower said hanger 43. The hanger 43 extends through one of the perforations or openings of the loramiA nous member 39, and under normal conditions. has the lower end thereof loosely connected to the regulator member 35. The lovver end of the hanger, however,` has nuts te or other fastening means so that the regulator member 35 may the lower end of the hanger.

In operation, an initial reduction of atmospheric pressure in the Well 5 pulls air and gasolene into 'the outlet sleeve 37 of the The n'xiXt-ure is directed toward the inner Walls ot the foraminous member 39 to be broken up by air passing through the perforations or apertures of said member. The deiector il positively divides the discharge from the sleeve 3'? and said delector may be adjusted to increase and decrease the restriction at the lower end of the foraminous member. Furthermore, the first suction impulse in the `Well 5 tends to raise the regulator member 35 which Will increase the space for the outlet of air between the nozzle and the regulator member. As the regulator member is raised the openings 36 thereoi' are graduallv brought into communication With the Weil 5, admitting air thereto so that the air may enter the lovvermost pcriorations or apertures for the ioraminous member and commingle with the mixture passing through said member.

n account of the resilient arm 38 resting on the regulator member 35 al movement of the member 35 will impart sutcieut impetus to the auxiliary valve 33, to coperate with the'suction in the cap 25 in raising the auxiliary air valve, thus allowing air to enter the cap and break up the mixture within the toraminous member at all sides thereof.

When it is desired to obtain a very lean mixture, the regulator member 35 may be iixed relative to the hanger 43, so that by be fixed relative to meses@ rotating the rod 40 the regulator member may be raised to a desired height to permit of a desired quantity of air passing through the openings 36 and between the nozzle 22 and the regulator member 35. By the outlet sleeve 37 moving to and from the deeetor il a restriction may be accomplished within the foraminous member, besides the restriction with Which thel spray nozzle 22 forms a part.

irrespective of how fuel or nir are admitted to the nozzle 22, members 35 and 39, these elements constitute an outlet member that is applicable to various types of mixing devices, and While it is thought that the operation and utility of the method ,of automatically regulating the mixture of air and gasolene by the device will be apparent to those skilled in producin explosive miie tures, it is to be understoo that'the structural elements disclosed in the drawing are susceptible to such changes in size, shape and manner of assemblage as fall Within the scope oi? the appended claims.

'What il claim is l. An outlet member for a mixing device, comprising a spraying nozzle having a 'fuel inlet at the lower end thereof and the upper end thereof provided with tangentiall dis posed grooves, an inverted conical s aped foraninous member above said spray nozzle and supported independent thereof, a regulator member on said spray nozzle having an interiorly grooved outlet sleeve extending into said foraminous member adapted to cooperate with said spray nozzle in imparting awhirling movement to a mixture -liquid et injected into said oreminous member, a de Hector in said oraniinous member, and a connection between said deiieetor and said regulator member and extendingf through said oraininous member so that said re lator member may be moved by said e- Hector.

L. i miningy device comprising body provided with an air Well a valveway, a nozzle in the air Well ont said body adapted for communication with a suitable supply oi liquid, a regulator member slidable against the 'walls et said vsive-Wayy and controlling the initial admizture air and' nozzle, a cap on said body provided with air intake openings, an automatically actuated auxiliary air valve slidable between said air well and the Walls oie said cap and controlling tire admission oaf air to said cap, an inverted conical shaped oraminous member in cap adapted to receive 'tile mixture from said regulatcr meinber, an adjustable deilcieetor .said teoremi neus member adapted te direct the mia ture against the 3 walls seid member to be broken 'up by entering seid cap, and connection between saidl detieetor and said regulator through said fora ineus member se that said regulator mei r inejy be usted in the well et said boey by said deiiecterx in testimony wheree li my signature in the presence et two Witnesses.
