9 Claims.

This invention relates to liquid sprayers and is concerned more particularly with paint and other sprayers including those of the gun type carried and moved by the operator's hand, usually with a rubber tion to a relatively tank containing air under pressure.

The conventional paint gun of the type referred to has been lfound unsatisfactory because the arrangement of it parts requires the operating hand and wrist of the user to assume awkward, unnatural and inconvenient positions relative to his arm in order to hold the nozzle in the proper with the result that the operators wrist and arm become so fatigued that he cannot operate the gun for more than a minute or so continuously, with a consequent impairment in his emciency and the' quality .of work done, and loss of time to accomplish a given assi8nment.

It is accordingly an object of my invention to provide a gun of the type referred to having the stationary air compressor or Aadvantages of conventional guns and none of the above-mentioned disadvantages.

A further object is to provide a gun so balanced that its nozzle may be held with complete comfort and minimum fatigue in proper juxtaposition to the surface of to be treated. irrespective of the volume of the contents oi' the can and ir- Points.

It is also an object of my invention to provide a paint gun in which the handle also functions as the connection between the nozzle and the paint can carried therewith.

Another object is to provide a gun of the type referred to formed to be used interchangeably with a can to be carried therewith or with a hose leading from a stationary source o1' liquid supply.

An additional object is to provide a gun having the advantages referred to using a conventional supply can.

Further objects and advantages of my invention will appear as the description proceeds.

The word paint is used herein not by way of limitation but for convenience to obviate the necessity of using the term treating liquid.

The invention will be better understood upon reference to the following description and accompanying drawings, in which:

Fig. 1 is a longitudinal view, mostly in section, some of the parts being in different planes, through a gun embodying features of my invention, showing the air and paint conduits and taken as indicated by the line I l in Fig. 2.

Fig. 9 is a side elevation in Fig. 1.

Fig. 10 is a top plan view of the device, taken as indicated by the line Il l in Fig. 9.

Fig. 11 is a fragmentary section-elevation slmilar to the portion projecting down into the can in Fig. 1 but modified for connection with a hose from a stationary paint supply.

Referring more particularly to the drawings, I have shown in Figs. 1-10 an embodiment of my invention in which a paint can is connected with the nozzle as a portable unit.

In Ythis form of the invention, there is provided a nozzle body I5 and a handle Il therefor of the structure shown preferably cast integral and preferably with their ply hose 21 at a axes in substantially the same plane, the handle being contoured to fit comfortably in the hand, and forming preferably an obtuse angle with the forepart I9 of the nozzle body, the angle being selected with an 'eye to permitting the hand and wrist to be held in natural, unstrained positions relative to each other and the operators arm when the device is normally in use. This angle accordingly is preferably about A- paint can 2 I detachably carried by the handle completes the assembly which is carried as a unit in the hand of the operator.

The handle I1 has preferably in the lower part thereof a lateral bore 23 tapped at its outer end 25 for connection to a compressed air suppoint below the hand on the handle. The other end of said bore meets a longitudinal passage 29 whose free lower end is closed as by a cleanout plug 3| engaging a gasket I3 and whose upper end meets the inner end of a bore 35 Awhich extends preferably longitudinally of the nozzle body I5. The .free end of the borev v29 by a valve element 43 engageable with the shoulder or seat 45 between the bores 35 and 4|. The valve element is detachably mounted as by means of a screw 4| on the end i9 of a valve stem. 5I, said end being of smaller diameter than the bore 4I to afford an annular passage 53 therebetween. The stem 5| has an enlarged portion 55 slidably fitting the bore 9| and providing therewith suitable bearing to properly guide the stem in its reciprocations. A packing gland 5l is tted about the enlarged portion 55 of the stem 5| and in a counterbore 59 at the front end of the bore 4|. The enlarged portion 55 of' the stem has a flange 6| between which and the gland 5i a coil spring B3 is disposed under an initial compression to insure the closing of the valve element 43 when opening pressure thereon is not applied by the operator.

lA trigger 55 preferably of stamped sheet metal or other material, and having yoke arms 51 hinged as at 39 to the nozzle bodypw, has an actuating portion slotted as at 1| and straddling a forward portion 13 of the stem beyond the flange 0| of the stem. The tongue or hook 15 of the trigger extends downwardly preferably in front of and normally spaced from the upper part 'il of the handie, where the hook is conveniently pulled by the operators iorenger A, second finger or both. The stem 5| has a flange 19 which cooperates with the flange 3| in retaining the trigger 65 in properly assembled relation to the stem.

'I'he nozzle body |5 has an open recess 8| accommodating the gland 51, spring 63, flanges 6| and 19 and trigger 35.

Extending upward from the bore 4| is a port 83 which terminates in another longitudinal bore 85 in the nozzle body I5, the rear end of the bore 85 being closed as by a cleanout plug 81. The bore 85 terminates forwardly short of the forward end of the nozzle body I5 and communicates with the front of said body by means of a passage 99. 'Ihe passage 89 leads to a circular cavity 9| in the front of the nozzle body.

A member 93 hereafter referred to in more detail is detachably mounted as by a snug fit in the cavity 9| at the front of the nozzle body so as to give said cavity an annular shape. Fitted about the member-93 is a iet member 95 abutting the front of the nozzle body and having a flange 91 with which a flange on a nut 99 engages, the nut being threaded at I 0| on the nozzle bod-y to maintain said jet member in leakproof engagement with the nozzle body. The member 93 is exteriorly fluted at |03 and is spaced from the front of the jet member 95 as shown at |05 so that clear passage is provided from the bore 89 to the annular space 9|, forward through the fiutes |03 into the space |05 and through the jet opening |01 to the outside.

From the foregoing, it is apparent that air under pressure introduced at 23 will follow the arrows I09 up the passage 29 and, when the valve 43 is open, enter the annular passage 4I, continue through the port 93 into the bore 85 and continue through the bore 89, annular passage 9|, flutes |03, space |05 and opening |01 to the outside.

A continuation of the port 83 is shown at -body I5.

extending down from the bore 4I and terminating at the upper end of a bore I '3 which may extend alongside the -bore 29 in the handle I'|, the bore I I3 terminating at the lower end of the handle. The handle |1 has a flange II5 adjacent the lower end thereof. Below and in engagement with the flange IIB is a gasket ||1^in turn engaged by an adapter II9 having an inwardly extending ange |2| disposed about a lower threaded sleeve |23 extending from the handle l1. A nut |25 is threaded on the sleeve |23 and engages a gasket |21 contacting the underside of the ange |2I. Thus, when the nut |25 is tightened on the sleeve |23, the adapter ||9 is sealed and secured to the handle. 'I'he adapter M9 is internally threaded at |29 to receivethe-threaded neck |3| of the paint can 2|, said neck terminating in an inwardly directed flange |33 engaging a, gasket |35 which seats against a shoulder |37 on the adapter to provide a leakproof connection. The sides of the nut |25 are spaced from the adapter H9, gasket |35 and paint can neck |3| to provide clearance as shown at |39. The adapter has a recess |4| communicating with the bore |I3 in the handle, and a port |43 which establishes communication between the recess |4| and the space |39 and consequently with the interior of the can above the level of the paint |41.

A needle valve |49 controls the flow from the port to the passage |I3 in the handle. Accordingly, when the valve 43 is open, admitting air from the handle passage 29 to the bore t the needle valve |99 may be adjusted to vary the air.

pressure on the paint |41 in the can 2|.

The handle i1 has another longitudinal bore |5| which terminates downwardly in the sleeve |23. Said sleeve is interiorly threaded and threadedly receives a collar |53 to which is secured a tube |55 extending upward substantially throughout the length of the bore I5I and having its opposite end |51 secured in a reduced bore |59 extending from the upper part of the -bore |5I. A further reduced bore IBI extends from the bore |59 and terminates at its upper end |53 in a transversely disposed passage (Figs. l and 5) extending longitudinally in the nozzle The rear end of the passage |65 is closed as by a cleanout plug |61. 'Ihe passage |65 terminates forwardly short of the front of the body I5. 'I'he forepart I9 of the body member I5 has a longitudinal bore |59 which communicates with the passage |65 by means of a lateral channel |1I, the outer end of which is suitably closed as by a plug |13. The valve member 93 (Fig. 1) has a sleeve extension |15 securely fitted in the forward end of the bore |69 and, in ad- Vance of the sleeve |15, has a tapered forwardly converging seat |11 terminating immediately behind the rear end of the jet passage |01 in the jet member 95.

Threaded in the bore |69 in the nozzle lbody I5 is a packing gland adapter |19 in which a packing gland is threaded. A forward extension |8| passes through the gland |80 and has a forwardly converging tapered end |83 adapted to be yieldably held in snugly fitting contact with the valve seat |11 by the spring 63.

Secured fluid tight to the nut |25 is a. flexible tube |89 whose lower end is embedded in a lead or other Weight I 9| o'f spherical or other suitable shape, adapted to rest on the bottom I 93 of the 'can 2| in such a manner as to at all times hold the open end |95 of the tube |89 adjacent and free from said bottom for the entrance of paint,

- tical. It has been explained how, in response to a pull v on the trigger Il, air finds its way to the jet openn nexium: of ine sul permitas; me weight to move to the lower part of the can regardless of the position of the can,'to insure constant supply'oi' paint even when the nozzle body is vering |01 and, under the control of the needle valve |40, such air also finds its way to the upper part of the can'2| to exert pressure on the paint |01.

The pull on the trigger 05 also draws the tapered and beyond the jet opening |01.

A trigger guard |91 extending forwardly from 4 the handle I1 is so located as to be engaged with the upper side-of the. third finger of the hand embracing the handle. When the hand thus embraces the handle, the center oi gravity of the entire appliance including the paint can 2| and its contents extends substantially in a plumb line passing approximately through the point B, so that when the operator is using the appliance with a horizontal jet, i` e., with the axis of the nozzle body I5 substantially horizontal, it is not necessary for him to hold his hand and wrist in an unnatural position or exert upward force at the wrist and hand to maintain the nozzle body in the proper position for such service.

The distribution of weight is such, moreover, that the appliance is balanced approximately in the vicinity of the pointB, regardless whether the can 2| is substantially full or nearly depleted.

In the embodiment of the invention chosen for illustration, the nozzle body I5 simulates generally the streamline shape of a bullet. To cany out that motif, I have provided a cap |99 which has near its rim an inwardly projecting rib 20| which is adapted to snap over the rear end 203 of the nozzle body and into a circumferential groove 205 in said end. Said end of the nozzle body is provided with a generally longitudinally extending recess 201 extending forward from the groove 205 and providing an entrance for a screw driver or other tool to facilitate attachment of the cap. Said cap, when in place, conceals the plug I1, pin 39 and plugs 01 and I 61 at the rear end of the nozzle body. v

The appliance is preferably provided with a hook 200 by means of which the appliance may be suspended from any suitable fixed partwhen not in use. 4

In the event it is desired to use the nozzle in connection with a stationary paint tank, the adapter-'I lil and tank 2| would be dispensed with and the nut |25 and associated tube |00 and the weight |0| would be replaced by a hose coupling nut 2|| carrying a hose coupling 2|! projecting downwardly from the nut to receive a hose 2|! which may extend to the stationary paint tank (not shown).

Various modifications may suggest themselves to those skilled in the art without departing from the spirit of my invention and, hence, I do not wish to be restricted to the specific form shown oruses mentioned, except to the extent indicated in the appended claims.
