CASWELL, OF SAND'USKY, OHIO .ADJUSTABLE VARIABLE FLOW LIQUID DISPENSING NOZZLE Application filed October 28, 1929. Serial No. 401,916.
This invention relates to a nozzle of the seat. The valve seating surface is prefertype commonly employed for the dispensing ably faced with fibrous material 6. i of liquids such, for instance, as gasoline at A main valve 7 has a conical surface seatfilling stations, and particularly relates to ing on the edge of the valve seat 6 and has 7 a manually controlled variable flow valve a stem portion 8, which is smaller than the for such a nozzle. opening 5 to adapt it to project down In the use of nozzles of this character, it through such opening and to provide a is exceedingly diflicult, if not impossible, to space therebetween, and has a series of circontrol the quantity of flow where it is decumferentially spaced webs 9, which extend 1O sired to discharge 3, lesser amount than full lengthwise thereof in co-action With the capacity flow and it is also diificult to iniwall of the opening 5 to guide thereciprotially open the valve due to the pressure of catory movements of the valve therein. the. liquid thereagainst. The valve 7 and its stem have an opening The object of my invention is the provi- 10 provided axially therethrough and this 15 sion of a valve of the character described opening is provided in its wall immediately which is manually operable in an easy manbeneath the valve head 7 and between the nor to effect any desired partial or full open- Webs 9 With orifices 11 through which liqing of the valve, depending on the demandv uid which enters the top of the opening 10 of the particular case, and is also adjustable may discharge, as hereinafter described.
29 to suit the particular job or installation A e ondary Valve 12 is disposed above requirements. 1 the valve 7 and provided with a conical suri inv ntion i full d ib d in th face which seats against the upper edge wall following specification, and while in its 0f e p ing 10 o adapt it to close such broader aspect it is capable of embodiment p ning, and has a stem 13 projecting down- 5 in numerous forms, a preferred embodiment iward therefrom through and below said thereof is illustrated in the accompanying p g with the lower Portion thereof drawings, in which, ting the opening to guide the reciprocatory Figure 1 i a sid elevation of a, no zl movements of the secondary valve relative embodying my invention, w th parts in ceut0 h m in valvetral vertical section and pa s broken away. The stem 13 near its upper end is reduced Fig. 2 is an enlarged side levationof the in size so as to provide a space 14 around valve removed from the nozzle. Fig. -3 is the stem within the opening 10 at its upper an enlarged cross-section on the. line 3-3 in end. When the valve 12 is unseated, liquid Fig. 1 and Fig. 4 is an enlarged view of is permitted to fl I' Igh th space 14 5 th valve ith parts i ti and thence through the orifices 11 and down' R f i to th drawings, 1 designates between the webs 9 to the discharge end of a nozzle embodying the invention, which is the The 7 1S lireferably adapted to be connected by a flexible hose provlded at Its uPper Inner edge wlth fiber 40 or otherwise to a source of liquid supply sif 15 f g f vaive undgr pressure and which has the discharge to recii i dgh e s dating tl iri i st df a diilgd d iii con uit 2 therethrough. Disposed in the conduit 2 is a valve chamber 3, in the prespresslon spnng whlch 1s dlsposed m the h 1 ent Instance, of cyl ndrical form and hav- Eggs g ig gz j i g g fi Zi end 45 ing its top closed by the removable closure The Valve Stem 13 has a Ortion 17 member T bottomfif fll 3 jecting downward without tlie side wall of has F Ppenmg 5 therem p l g the conduit 2 through a stufling box 18 promunlcation between spaced port1ons of the, id d therein and engaged at its outer end conduit and forming a valve guide, and by a trigger member 19, which is pivoted to also, at its upper marginal edge, a valve the conduit casing at 20 and has its free end forming a finger engaging portion which trigger to extends lengthwise of the upper horizontal portion of the conduit 2 in position to be operatedby a hand gripping such portion of the nozzle. The trigger 19 is protected by a guard 21, which has co-action with the limit its outward movement. stop nut 22 is threaded on the valve stem 13 below the stem 8 of the main valve 7 and in pre-determined spaced relation thereto so that the valve stem 13 when first moved by the trigger 19 will efiect an opening of the valve 12 relative to the valve 7 and then by a continued movement thereof effect an opening movement of the valve 7.
It is important in practice to have the stop installation.
It is apparent that very little pressure is required to be exerted on the trigger 19 to initially raise the valve 12 from its seat, and furthermore that if it is desired to have a very slow flow through the valve it can be easily held in only partially open position without the chattering and other difliculties encountered in the use of an ordinary type of valve. If a greater flow than that permitted to take place through the valve 7 by an unseating of the valve 12 is desired, the trigger may be further raised to cause the stop 22 to engage and efiect a raising of the valve .7 to permit a flow to take place both through such valve and downward through itsseat around its stem.
I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications and changes without departing from the spirit of the claim. 2 Having thus described my invention, what I claim as new and desire to secure by Lettors Patent, is,-
The combination with a liquid nozzle casing having. a discharge conduit therethrough,
and a valve chamber in said conduit with an opening in its bottom forming a valve seat at its open marginal edge, of a main valve seating on the valve seat within said chamber and having a stem portion projecting through said opening, said stem portion being spaced and having portions in guiding co-action with the opening wall, said valve and stem having a central opening axially therethrough and the stem having side discharge ports from said axial opening and into the space between it and the bottom opening wall, a secondary valve disposed within said chamber and seating against the upper edge I both valves,
with the wall of the valve opening and having a stem portion projecting downward through the valve and stem opening and thence through aside of. the nozzle casing, said stem having a reduced portion at its upper end which, when the secondary valve is unseated, permits the flow of liquid through the opening of the primary valve to said means adjustably carried by secondary valve in predetermined spaced'relation to the stem of the primary valve for co-action therewith to open it when the secondary valve has been opened a predetermined extent, a spring acting on the secondary valve to normally effect a seating of and manually operable means without the nozzle casing for imparting an opening movement to the stem of the secondary valve. I
In testimony whereof I have hereunto signed my name to this specification.
