2 Claims.

This invention relates to spray guns. It has for its object the provision of a trigger actuated gun adapted to be connected to and derive its fluid pressure from the standard type of hose commonly employed at automobile servicing stations.

The invention concerns itself particularly with means for securing the coupling of the air hose with adjustable tension to the gun in fluid tight manner yet with sufficient freedom to permit the gun to be oscillated to the right or left in the act of spraying without necessitating bending of the air hose.

Another object of the invention is to provide the gun handle with a socket or recess for the coupling having a clamp for holding it in place and a projecting nipple adapted to enter the coupling and serving the dual purpose of opening the air valve in the air line and serving as an axis for the relative rotation of the gun with respect to the hose.

Still another object of the invention is the provision in a spray gun of a nozzle constructed to cause the impingement of laterally directed air jets against a jet emanating from acentral tube, said nozzle being adjustably orientable for changing the direction of the flat spray without altering the longitudinal relation of the lateral jets to the central tube.

Other objects of the invention will appear as the following description of a preferred and practical embodiment thereof proceeds.

In the drawings which accompany and form a part of the following specification and throughout the several figures of which the same characters of reference have been employed to designate identical parts:

Figure l is a vertical elevation partly in section of a spray gun embodying the salient features of 40 our invention;

Figure 2 is a front view of the nozzle;

Figure 3 is a vertical section through the nozzle and the adjacent portion of the spray gun;

Figure 4 is a horizontal section taken along the 45 line 4 4 of Figure 1, looking up;

Figure 5 is a side elevation partly in section showing a modified form of the invention; and

Figure 6 is a side elevation partly in section of the handle of a spray gun illustrating a further 50 modification;

Referring now in detail to the several figures and first adverting to that form of the invention shown in Figures 1, 2 and 3, the numeral represents the spray gun body which is suitably fitted 55 to the screw cap 2 adapted to screw on the mouth of a jar 3. The body I has a boss 4 projecting through an aperture in the cap 2 and secured by means of a suitable washer 5 and lock nut 6. A gasket 1 is preferably provided between the top 60 of the jar and the inside of the cap to prevent leakage. The cap 2 is provided with an air vent passage 8 which communicates with the interior of the jar through alined apertures 9 and In in the cap and gasket respectively. A pin projecting from the lower face of the body through the cap 2 and into the gasket 1 determines the initial alinement of theparts. The air vent passage 3 preferably opens on the opposite side of the jar to that having the apertures 9 and I0 so as to prevent the paint or other liquid in the jar from spilling through the vent should the jar be overturned or tilted to an extreme position as when spraying a ceiling.

The body of the spray gun has a bore l2 preferably extending along its vertical axis, into which is screwed a tube H to a point adjacent the bottom of the jar for drawing up the liquid to be sprayed. The body is provided also with a pas sage M communicating with the bore l2 and communicating with a fine bore l5 extending longitudinally through a spray head l6 screwed or otherwise secured to the working end of the body A needle valve ll controls the rate of flow of the liquid through the passage It. Said needle valve screws against the tension of a spring l8 which prevents it inadvertently changing its adjustment.

The body is provided with an air passage l3 which extends also through the handle 20, being interrupted at an intermediate point by a ball valve 2| urged to closing position by a spring 22. A nut 23 screwing against the spring affords an adjustable tension for the valve. The valve is opened by a plunger 23 normally kept out of contact with the valve 2| by means of a spring 25 under compression between a shoulder 26 on the wall of said passage and a collar 21 on the plunger. The plunger is slidably mounted in a removable plug 28, and has an extending end 29 adapted to be engaged by the finger operated trigger 30. When so engaged the plunger moves inwardly against the tension of the spring 25, contacts with the ball valve 2| lifting it against the tension of the'spring 22 and opening the passage l9. The portion of the passage which passes through the handle 20 terminates in a nipple 3| projecting slightly beyond the face 32 of the recess or cleft 33 formed in the lower part of the handle 20. Said recess is large enough to admit the coupling or chuck 3d of the air hose 35. When the air hose is in place the projecting end of the nipple 3| enters the cylindrical mouth of said coupling and forms an axis about which the spray gun can turn. The coupling is held in tight relation against the face 32 by a thumb screw 36 threaded through an aperture 20' in the handle 2|] and engaging the back of the coupling 34. The thumb screw 36 may be adjusted so as to press the coupling against the face 32 with enough pressure to assure a fluid tight joint and yet with insufiicient pressure to til prevent the oscillation of the spray gun relative to the hose in the act of spraying, the coupling swiveling around the projecting end oLthe nipple 3| in the manner described, the hose being able to pass freely through the open sides of said chuck.

The working end of the body of the spray gun is externally threaded as at 31 for the reception of a ring nut 38 having an inwardly extending flange 39 at its inner end. The adjacent end of the body of the spray gun is provided with a circumferential rabbet 40 forming a shoulder upon which seats the flanged edge 4| of the spray nozzle 42. The outer side of said flanged edge is formed as a shoulder 43 by means of whichthe nozzle 42 is retained beneath the flange 39 of the ring nut. The nozzle 42 may be screwed tightly against the body I so as to fix it in any position of orientation. Said nozzle has a chamber 44 at its inner end communicating with the air passage I9, and having inclined ports 45 and 46 communicating with said chamber and with the flared opening 47 which forms the mouth of said nozzle. When the nozzle is in place, the end of the spray head l6 projects slightly into the mouth 41. The inclined ports 45 and 46 are on opposite sides of the end of the spray head and their eifect is to flatten the jet of liquid issuing from said spray head. By loosening the ring nut and turning the nozzle 42 to any desired angular position, the plane of the flat spray may be rotated about the axis of said nozzle.

While in our co-pending application Serial No.-

698,516, filed November 17, 1933, we disclosed a means for rotating the nozzle so as to angularly shift the plane of the flat spray, yet in said application the adjustment was accomplished by screwing the nozzle on or oiT, which necessarily changed the relation of the outer end of the spray head I to the ports 45 and 46. By the use of the ring nut, rotation of the nozzle can be accomplished without changing its longitudinal relation to the spray head.

An adjustable needle valve 48 controls the air flow to the nozzle chamber 44. In the form of our invention shown in Figure 1, the handle and body are united by conventional means such as the threaded connection 49.

It is obvious that when the coupling of the air line has been screwed into a fluid tight position as illustrated in Figure 1. the projecting end of the nipple 3| has pushed back the valve of said coupling and the control of the air admission to the body of the spray gun is a function of the valve 2|.

Figure 5 illustrates a modified form of the invention to the extent that the handle is clampably secured to the body portion both to make mechanical connection and at the end an airtight joint between the parts of the air passage IS in the body portion and handle. In this form of the invention the handle terminates in a socket 50 connected to the handle by a threaded nipple 5|. The socket member has a concave seat 52 in the face of which the portion of the passage IS in the handle opens. The body portion l of the spray gun has a nipple 53 screwed in the end thereof having a bore forming part of the passage IS, the end of said nipple being convex to correspond to the concave seat in the socket 5D.

A nut and lock nut 54 and 55 respectively, are threaded on the nipple 53 and a'clamp hook 56 suitably secured to the handle has its bifurcated end 51 straddling the nipple behind the nut and engaging the latter. By screwing up the nut 54 against the clamp hook, the end of the nipple is buried into the seat of the socket sufflciently to produce a fluid tight joint while at the same time rigidity is imparted to the connection between the body of the spray gun and the handle. In other words, the nuts 54 and 55 are adjustable on nipple 53 to vary the tension of the clamp hook in holding the nipple to its seat 52. This variable spring tension enables the operator to connect the handle to, or disconnect it from, the spray gun, merely by inserting the convex end of the nipple in the seat 52 and rocking the handle about said seat.

In this form of the invention the valve 2| and its appurtenant operating elements are similar to those described in connection with Figure 1 excepting that the trigger 58 extends downwardly along the handle instead of upwardly and its amplitude of actuation is determined by a spring pressed plunger 59, the end 60 of which projects into contact with the trigger. A set screw 6| presses against a cap 62 on the end of the spring and can be screwed in or out to regulate the tension of the spring, adjusting the resistance of the trigger to the comfort of the individual hand.

Figure 6 shows still another form of the invention, the distinctive feature being the means for holding the coupling of the air hose into operative position, which instead of being a thumb screw as in the first described form of the invention is a pivoted jaw 63 forming part of the handle. The end 64 of the jaw embraces the head of the coupling bearing upon it substantially in the axis, produced, of the nipple 3|. The pressure of the jaw is regulated by means of a set screw 65 threaded into said jaw and which may be screwed in or out.

While we have in the above description defined what we believe to be a preferred and practical embodiment of our invention, it will be understood by those skilled in the art that the details of construction as illustrated and described are merely by way of example and not to be construed as limiting the scope of the invention as claimed.

What we claim is:

1. Flexible joint for an air conduit comprising a member having a cleft in its end opening on two lateral sides and its rear side, giving access to an air hose chuck, a nipple projecting from one wall of said cleft being the terminus of a conduit passing through said member, said nipple forming a pivot joint adapted to enter the nozzle of the air hose chuck for swivelly connecting the same to said member and opening the air check valve in said chuck, and clamping means at the opposite wall of said cleft positioned to apply pressure to said air hose chuck substantially in line with the axis of said nipple, for sealing said chuck against leakage while permitting the air hose to swing through the open sides of said cleft.

2. Flexible joint as claimed in claim 1, said clamping means including a movable clamping jaw constituting the side of said cleft opposite said nipple.
