` DISPENSING- NOZZLE Appneation mea 'April 15,

My invention consists of a .novel construction of a dispensing nozzle for Veecting the conveying of compressed air or other fluid to a desired pointy by means of a handle or body member, a fixed pipe therein, a slidable plunger mounted on said pipe and having a transverse flange adaptedv to effect the actuation of the valvular elements, said plunger `being suitably packed and under tension withrespect to said fixed pipe whereby pressure or movement of the handle in one direction will open the valvular elements, and releasing or cessation of the handle pressure will automatically effect the closure of the valvular elements.

lt further consists of a novel construction of a slidable plunger having a terminal conical seat, adapted to coact with the closed ported end of a fixed pipe mounted in a suitable handle or body.

It further consists ofa novel means for concealing and protecting the end of the fixed pipe member aforesaid.

lt further consists of other novel features of construction and advantage, all as will be hereinafter pointed out in the specification and claims appended hereto.

It further consists of a novel dispensing nozzle wherein the shut off is effected at the extreme end of the discharge orice, thus preventing any drip or wastage of the dispensed fluid after the nozzle has beenclosed.

F or the purpose of illustrating my invention, l have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of whichmy invention consists can be variously arranged and organized and that my invention is not Y limited to the precise arrangement and organization of the instrumentalities as herein y shown and described.

In carrying out my invention, l employ a tubularcylindrical body orl handle memberl having a rear inlet chamber 2, which is threaded at 3 for the attachment of a suitable hose-4L, which is locked in position with respect to the handle memberl by the nuts 5 and 6 seen in Figure 1. 'I designates a spring chamber or plunger chamber withmember in openl in the handle member 1, whichV is .separated i from the rear inlet chamber 2 bythe partil tion 8, said spring chamber having the vent or port 9 openingjthereinto from the atmosphere. lOdesignates a fixed inner pipe or stationary tubewhose rearend is tightly fitted 0r fast in the partition 8 and is secured thereinby the washer 11y and the Iiut v12. 13 designaties a slidable plunger which is fitted within the chamber 7,`so as to be readily reciprocated therein,.the rear end of said plunger be- A ing provided with a packing 14 and a packing retainer'15-contiguous to the spring 16, one` end of which latter bears against said packing retainer 15 while its other end bears*againsty the contiguous wall ofthe partition 8 as willbe understood from Figure 2. The fired in-l ner pipe or tube lOihasits frontend closed` as indicated at 17 and is provided with the outwardly flared terminal ,conical wall 18 having a port 19 therein, said flared terminal wall 18 being seated in the conical lseat 20 in the, front end 23 of the nozzle by reason ofthe ten-v sion of the spring 16 when the parts are in the position ,se-en in Figure 2. 21 designates aA flange extendingtransversely to the slidable i plunger 13 and preferably integral therewith and normally. positionedv with respect to the end 22 of the handle member 1, substantially as seen in Figure 2'when the`port'19 is closed, the spring ,'16 serving automatically `to .hold the jslidableplung'fe'r 13 with respect to theI fiXed inner pipe 10 normally substantially as seen in Figure 2. When it is desired to convey fluid to the desired point as to a transmission, it is only necessary to insert the forward end 23 of the nozzle into vthe opening of said tra-nsmission until the flange 21 contacts with the Wall of said transmission and to push the handle member 1 forwardly whereupon the parts will assume the position seen in Figure 3, the port 19 being open and fluid under pressure being discharged from the hose 4 through the fixed pipe 10 and port 19 to the desired point. Upon removing the fiange 21 from the wall of the transmission or releasing slightly the grip or grasp upon the handle 1, the parts move from the position seen in Figure 3 to the position seen in Figure 2 by reason of the tension of the spring 16 the contact of the walls 18 and 2O limiting the eX- tent of forward movement ofthe plunger 13 as is evident. In the construction seen in Figure 4, I have shown a slightly modified form of device for protecting the end of the fixed pipe wherein the fixed pipe is indicated as 24 and is provided with the flared end 25 closed by the relatively thick wall 26 and provided with a port 27. The flared -end 25 is normally seated against the conical wall 23 of the plunger 33 as seen in Figure 4 and the closed end 26 reciprocates and is protected in the chamber 29 which is provided with the main exit port 30 and the vent port 31. The vent port 31 is preferably positioned in a cap member 32, which is in threaded engagement with the front end of the plunger member 33, which is provided with a flange 21 of the same character and function as seen in Figures 1 to 3. A

It will be understood that the right hand portion of Figure 4 is constructed similar to the right hand portion of Figure 2, in respect of the threaded portion 3, the partition 8, vent 9, packing 14, and nut 12, so 'that when the flange 21 seen in Figure 4 is pressed against the wall of the chamber into which it is desired to introducev fiuid,the port 27 will align with the port 30 and fluid can flow from the hose 4 through the fixed pipe 24 and ports 2'2"V and 30 to the desired point. The vent 9 permitsthe escape of air when the spring 16 is compressed, and the vent 31 similarly functions when the plunger 33 is actuated with respect to the fixed pipe 24.

I am aware that the invention maybe embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention. n

Having thus describedmy inventiomwhat ters Patent, is

I claim as new and desireI to secure by Let-l l. In a device of the character stated, a handle member, having a rear inlet chamber adapted for a hose attachment, a front plunger chamber, a partition separating said chambers, a pipe fixed in said partition, open at its rear end and closed at its front end and provided with an outwardly flaring, conical, terminal portion having a port therein, a plunger carried by said handle and slidable longitudinally upon said fixed pipe, and having a front terminal conical seat conforming to the lr front contour of said iXed pipe, a flange on the front of said plunger, and a spring intermediate said partition and the rear of said plunger.

V2. In a device of the character stated, a handle member, having a rear inlet chamber adapted for a hose attachment, a front plunger chamber, a partition separating said chambers, a pipe fixed in said partition, open at its rear end and closed at its front end and providedwith an outwardly flaring, conical, terminal portion having a port therein, a plunger carried by said handlev and slidable longitudinally upon said fixed pipe, and having 'a front terminal conical seat conforming to the front contour of said fixed pipe, a flange on the front of said plunger, a spring intermediate said partition and the rear of said plunger, and an apertured cap for said plunger covering and protecting the end of said fixed pipe. y
