SPRAY GUN.

Application filed November 7, 1925. Serial No. 67,515.

My invention relates to spraying appliances-of the general class employed for projecting liquids in the form of a. finely divided spray. In onc'of its important objects, my invention provides a. construction of a manually operated appliance of thisl class which will permit the air supply to be drawn either through the handle of the appliance or through the upper rear end of the same.

In another object, my invention provides a spray appliance construction which will readily afford a plurality of definite gradations of the amount of air supplied to the nozzle of the appliance, and which will automatically vary the rate of flow of the liquid also in proportion to the variationsin the amount of air. Furthermore, my invention provides an appliance construction for these latter purposes which will be easily assembled and cleaned and which will readily permit an adjusting of the time interval between the admission of air and of liquid into'the nozzle of the appliance. Still further and also more detailed objects will appear from the following specification and from the accompanying drawings, in which Fig 1 is a central, vertical and longitudinal section through a spraying appliance of the so-called spray gun type embodying my invention. v

Fig. 2 is an enlargedtransverse section taken 'along the line 2-2 of Fig. 1.

Fig. 3 is an enlargement of portions of the section of Fig'. l. Fig. 4 is an ,elevation of the tubular valve body which houses the air control member.

Fig. 5 is an elevation of the air control,

member.

In the illustrated embodiment, my spraying appliance includes a body or barrel portion 1 carrying a rearwardly and downwardl extending handle 2, thebody being threa ed at its forward end 'to receive a forwardly tapering collar 3 which limits the forward pressing of a nozzle 4 by springs -5- interposed between the rear end` of this nozzle and the forward end of the body or barrel 1 of the appliance. This forward end of the body also has mounted on it .a core 6 provided with a liquid outlet 7 which is disposed axially of the nozzle 4 and to which liquid is supplied lthrough lan inlet 8, the outlet port 7 being controlled bya retractable needle 9 in the usual manner.

end of the body member, so as to afford an l operative connection to an air duct 12 which extends longitudinally of the body member and desirably adjacent to the top of the latter. The duct 12 has at its rear end a bend 18 leadinglto a bore in the body coaxial with thesaid nozzle and needle, in which bore the forward portion of a Valve body is mounted. This'iwalve body is shown in Fig. 4 as including an enlarged rearward por, tion 13 normally threadedinto the rear end of the body l of the spray gun, a diametrically contract-ed portion 14 forward of Athis threaded ortion and connected by a transverse perforation 15 with a valve chamber 16 in the valve body,.and ay more forward portion of still smaller diameter having intermediate its ends a groove affording a portion 17 of a diameter even smaller than that of the portion 14. When the valve body is threadedly att-ached to the body member of the appliance, the portion 17 is opposite the bent rear end 18 of the air duct 12, so

body from a hose 20, here shown as secured to a hollow nipple 21 threaded into the rear end of the valve body. This valve body has its bore contracted forwardly of the cham.- ber 16 as shown in Fig. 3,`so as to afford an annular seat 33 for a valve head 21 which desir-ably is' formed as an integral portion of the valve member or air control member of my appliance. This air control member is continuously urged forwardly by a com-4 pression spring 22 interposed between its rear end and an inwardly directed shoulder 23 within the nipple 21, the spring being desirably spirall and maintained in coaxialv relation to the said control member by a pin 24 threaded intp the rear end of the control member. This. portion of this control member immediately forward of the valve member 21 desirably has a generally cylindrical contour and is provided with a pluralit of peripheral grooves spaced longitu inally of the said member and consecutively increasing in width forwardly of that member, such as the grooves 25, 26 and grooves, as shown by the corresponding diameters of the bores 28, 29 and 30 in Fig. 3.

When the air valve is closed by a pressing of the valve head 21 against the annular seat 33 within the control member, the rearmost groove 25 alines with the transverse bore 19 in the control member so as to connect with the rear end 18 of the air duct 12 as shown in Fig. 3. As soon as the valve member is even slightlyT retracted so as to space the valve head 21 from the seat 33, air from the rear chamber 16 will pass through the groove 32 and the ports 42 into the chamber 31 of the valve or control member and will then pass through the smallest transverse perforation 28 and the narrowest groove 25 into the bore 19 and hence into the air duct 12. When thus positioned, the diameter of the bore 28 will limit the rate of flow of the air. If the valve or control member is retracted further, so as to bring the groove 26 opposite the connecting port 19, the fiow of air will be correspondingly increased, and this flow will again be increased if the valve member is retracted still further so as to bring the largest port 30 into registry with the connecting port 19.

To move the valve member for this purpose, I arrange it so as to be operated by the same lever 35 which retracts the needle 9 of my appliance. This lever is here shown as having a forked upper portion 36 straddling the body portion 1 of the spray gun and-as pivoted on a pin 37 extending transversely of that body. *The needle 9 has threaded upon it a nut 38, and to provide .for an operative connection between this nut and the parts 36 of the operating lever, I form the body of the gun of a skeleton shape having a lower horizontal bar portion 39 which e'xtends between the arms 36 of the said lever. This bar portion 39 of the body is narrower than the diameter of the nut 38, thereby permitting 'the arms 36 to be disposed in front of opposite lateral portions of the nut, and the operating lever also has a second pair of arms 40 extending upwardly past o posite sides of the bar 39 and disposed behind the nut438, as shown in Fig.

2. These rear arms 40 are spaced from their forward arms 36 b v a distance greater than the thickness of the nut 38, thereby permitting an adjusting of the nut 38 along the needle 9 which controls the liquid outlet port 7.

The needle 9 extends slidably through a bushing 41' threaded into the cylindrical forward end portion 43 of the valve member. and this needle has a head 43 disposed behind the bushing 41 in a chamber i5 which houses a spring 44 for continuously pressing against the head 43 to urge the needle 9 forwardly to its closure. position. 'ith the nut 38 threaded on the needle 9, the spring 44 not only holds the tip ot' the needh` 9 in its closure position but also limits the movement of the operatingr lever so as to hold the latter substantially in the position of Fig. 1 when my spray gun is not in operation.

On retracting the lever 35, the rear arm portions 40 first operate through their engagement with the bushing 41 for moving the valve member rearwardly, thereby connecting the air supply chamber 16 operatively through the duct 12 with an annular air projecting passage 46 between the core G and the bore of the nozzle 4. and also with the diagonal air ports 10. Vhen the operating lever 35 is retracted a little farther, so as to move the nut 38 rearwardly through its engagement with the forward arms 36, the needle 9 is also retracted. thereby opening the liquid discharge port 7 a little later than the effective opening of the air discharge ports, the time interval being controlled by the osition of the nut 38 on the stem of the nee le 9. The volume of the emitted air can be increased gradually by the further retracting movement of the operating lever until the latter engages a suitable stop, such as the stop screw 47 shown immediately above the needle 2 in Fig. l. By suitably forming the tip of the needle 9 in relation to the port seat enclosed by it, l can readily Secure an increase in the .supply of liquid l with such an increase in the volume of air. Consequently, my 'appliance eau readily be used either for projecting a quite massive spray such as that needed in the rapid coating of large surfaces, or for projecting smaller quantities of spray when relatively small surfaces are to be coated, or for projecting a still more concentrated spray when spots on a previously coated surface need to be touched up.

To adapt my spray gun still further to varying requirements, I dcsirably arrange it so that the connection to the hose 2() can be made either through the valve body as shown 1n Fig. 1 or through a hose connected to'the lower end of the handle 2. With this in mind, I provide the rear portion of the gun body with a bore 48 registering with lll-5 through the handle into a nipple 50.v It the' rear end hose connection is tombe used, this nipple is closed by acap 5l as shown in Fig. 1, but by interchanging this cap with the threaded attaching. member 52 of the hose. I can obtain the air supply through the handle so as to adapt my spray gun better for use in certain positions and for suiting the preference of certain users. By making the body of the gun Vpartly -i skeleton form, I provide convenient access to the nut 38 for adjusting this nut when desired. Likewise, by constructing the valve body as above' described, and by providing this valve body at its rear end with an easily rotated head 53,' I can readily detach the valve body, together with the valve meniber and the springs mounted in the latter from the body of the appliance, thereby making' it easy to clean these parts 'if desired. However, while lI have illustrated and described my invention. inan appliance of a pistol shape and one including various highly desirable features of construction and arrangement, I do not wish to be limited as to these, since manychanges might obvious.- ly be made without departing either from the spirit of my invention or from the appended claims.
