1 Claim.

This invention relates to spray guns for the applying of sound deadening material to surfaces of material which under certain conditions would give out sounds when impacted, such as in the case of closing automobile doors, or the like.

Among the objects .of the invention is to provide a novel spraygun for .handling a viscous material in which there is .a valved controlled passage passingto a nozzle where the material is sprayed by air under pressure, the passage being of ample size for affording full freedom for passage or flow of material to the nozzle, and the valve controlling such passage may be moved further than heretofore so as to effect a full open'- ing of the passage leading to the nozzle.

Another object of the invention is to control the valv-e by compressed air or the like, such as that which is fed to the gun to cause the sprayn ing of the material at the nozzle, so that the control Valve will be fully opened to afford a clear and full passage of the material through the pasu sage and to the nozzle, in lieu, as heretofore, of mechanically opening the control valve by a manual pressure on the trigger in mechanical association with the control valve.

Other objects, advantages, capabilities, features, and the like are compren-ended by the invention and as will later appear, and as are inherently possessed by the invention.

Referring brieiiy to the drawings:

Fig. l is a view in side elevation of an embodiment of a gun constructed in accordance with the invention;

Fig. 2 is a longitudinal sectional View of the same, showing a stage of use or operation;

Fig. 3 is a similar View, showing another stage of use or operation; and,

Fig. 4 is a transverse sectional view taken in a plane represented by line liin Fig. 2 of the drawings.

Referring more in detail to the drawings, the embodiment selected to illustrate the invention is shown as comprising a body i, a handle 2, a head 3, and a nozzle li. The body I may have a hook or eye 5 by which the gun may be hung or suspended, as from a hook, when the gun is not in use.

The forward end of the body I and the rear end of the head 3 are provided with sockets t and 1, and 8 and G, of which sockets ii and l are alined, and sockets 8 and 9 are alined. In sockets t and 'I fits a connector or union II). Sockets 3 and 9 are oppositely threaded for the threading therein of a similarly threaded connector or union Il 2 which, when 4turned .by a suitable tool, will tighten the body I and the head 3 together so that they will be in sealing abutment. The connector IIJ is hollow to afford air passage as later described.

'lhe head 3 has an air passage I 2 leading from the `socket 'I and the connector Ill, and to an annular channel I 3 provided in va forward threaded neck portion I4 of the head 3. The forward porA tion of the body I has an `air passage segment IEa leading to the socket 6 and the connector VIll for feeding air thereto.

The head 3 also has a material passage or chamber I5 of ample capacity for the facile movement of the material fed thereto from a duct :or hose (not shown) connected to a threaded neck portion I'I forming a part of the head 3, as shown in Figs. 2 and 3. The neck portion i4 of the head 3 has a threaded socket I8 in which is threadingly connected' a material nozzle Iii also having an ample -capacity passage 2D for facile movement of the material therethrough. This passage com municates at its rear end through an opening provided in the side of the passage i6 and has a valve seat 2i with which is engageable a. valve 22 connected 'to the forward end of a valve rod 23 slidably extending Ithrough the connector I l and in the gun body I, later explained.

The material nozzle I 9 has a forward nozzle orice part 24, where the material is ejected to he acted upon by compressed air to spray it, and fur-ther has a ange or collar part 25 adapted to sealingly abut with the forward yend of the neck part Iii of the head 3 to normally close oil the channel I3, but having a series of air orices or passages 2E connecting with the channel i3.

-On the flange 25 is seated a skirted portion 2l and a flange portion -28 of the nozzle cap 4, and with this lla-nge portion 28 is 'engaged a coupling,r ring 2S which has a knurled and threaded portion 30 for connection Aor `coupling with the threaded part of the neck portion Ill of the head 3. In this way the nozzle cap 4 is held in sealing contact with the flange 25 of the material nozzle I4. The forward end portion of the nozzle 4 has a discharge nozzle tip portion 3| provided with a discharge orice 32 -of ample capacity forthe projection of the atomized material .proceeding from the nozzle 24 and atomized 'by pressure air passing from the oriiices 26 by way of the annular air nozzle passages 33 and 313 .provided within the nozzle cap Il :between it andthe nozzle tip portion 24 of :the material nozzle lI 9 to communicate with the orice 32 where the material from the nozzle 241s aerated and atomized. e

The handle 2 has passages 35 and 36 of which the passage 36 constitutes an air passage, the lower end of which has a connector 31 for coupling with a pressure air hose or ductinot shown) and the passage 35 is normally closed by a suitable means, such as a screw plug 38. At the upper portion of the handle 2 are air chambers 39 and 4D of which chamber 39 communicates by way or an air passage 4I in the body I, which in turn leads to a valve chamber 42 communicating with a chamber 43 forming part of an air passage 44 connected to the air passage I2a. The chamber 43 is closed by suitable means, as a screw plug 45.

In the chamber 39 is a valve device comprising a valve body 46 suitably threaded into a threaded socket 41 forming part of the upper portion of the handle 2, and in the body 46 is a chamber 48 having air ports 49 for establishing communication between the chambers 39 and 43. The rear end of the body 46 has a sealing or packing means as a plug 56 for sealing olf the chambers 33 and 4i), and the forward end of the ybody 46 has a sealing or packing means 5I of any suitable form.

In these parts 53 and 5| is slidably mounted'a valve element 52 which is of tubular form having an air passage 53 and an opening 54 at its rear end to communicate with the chamber 4U, and having at its forward end transversed ports 55 adapted to establish communication between the chambers 48 and 53 when the valve 52 is in rearward or in position as shown in Fig. 3. Within the Valve body 46 and around the valve 52 is a spring 56 reacting between a suitable shoulder in the valve body 46 and the sealing elements of the sealing means 56. On the rear end of the valve 52 is a collar means 5'! adapted to abut against the sealing means 50 when the air Valve 52 is in shut-oil position (see Fig. 2), under the force of a spring 58 in the chamber 49 and reacting between the collar 5'! and the rear end wall of the chamber 46. This spring normally maintains the valve 52 in closed or forward position, as shown in Fig. 2, and yields when the Valve is positioned inwardly (see Fig. 3) into open position. The forward end of the valve member 52 has secured to it a knob or button B which may b e pressed by the operators ringer to eiect operation of the device.

Upwardly from the chamber 40 extends an air passage 59 leading to a diaphragm or piston chamber or cylinder 6D in which is reciprocably mounted a diaphragmatic member, such as a piston 6I, and rearwardly of the piston or like member 6I and in the rear portion of the chamber 69 is a spring 62 which reacts between the pistonlike member 6I and a closure cap 63 secured to the rear end of the piston chamber 60, to normally urge the piston forwardly (see Fig. 2).

Connected to the piston 6l is an air valve member having a body 64 slidable in a sealing means 65 secured, as by screw threads, to the body I at the rear of the chamber 42, and a seating portion 66 adapted to seat on a seat member 61 fixed in the body I at the forward end of the chamber 42 and between the chamber 42 and the passage chamber 43.

The material valve stem 23 is slidably mounted in this valve member 64 and extends rearwardly of the piston 6I where it has an adjustable head 6B, as threaded to the stem 23, and held in adjusted position by a lock-nut 69 also threaded to the threaded end of the stem 23. Between the head 68 and the cap 63 reacts a spring 'I9 to normally urge the material Valve stem 23 and the valve 22 in forward and closed position. The rear portion Zi of the piston 6I has a seat 'II against which the forward and tapered portion 'I2 of the head 63 may seat when the piston 6I moves rearwardly to effect an opening of the material valve 22.

The body I forwardly of the passage chamber 43 has a socket 'I3 in which is a sealing member 'I4 pressed by a spring 'I5 compressed by a plug 'I6 screwed into the socket 13, the member 'I4 acting to seal with the valve stem 23 and the hole in the forward wall of the passage chamber 43 in which the stem Z3 slides in its sliding movements. The connector II is provided with a chamber 'Il in alinement with a rear conical portion 'I8 of the valve 22 so that when the material valve 22 is moved into open position the portion 18 will extend into the chamber 11 so that the forward part of the valve 22 will be clear back and remote from the port of the valve seat 2| to afford free and unimpeded flow or movement of the material to the nozzle part I9 from the chamber I6. The rear portion 'I8 of the material valve 22 will be spaced from the forward end of the chamber 'I'I (see Fig. 3) to afford displacement of whatever material may have entered the chamber TI when the valve 22 is moved into open position.

It will be understood that the piston-like membei` 6I may be of the flexible diaphragmatic form and thus reciprocate the same as a sliding type of piston mem-ber, and still perform the same functions and operations as herein disclosed.

In operation, and with the gun in closed condition as shown in Fig. 2, wherein the material to be sprayed is under pressure to the closed valve 22 and the pressure air is held at the closed valve 5?., as also at the closed valve 66--6'1 the operator presses a finger against the button B to move the valve member 52 rearwardly and bring the ports 55 into communication with the chamber 39 (see Fig. 3), whereby the pressure air passes by way of passage 53 and port 54 of the valve 52 into the chamber 43 and thence by way of the passage 59 into the piston chamber 69. This air first moves the piston 6! rearwardly (against the force of the spring 62) with the valve 54 to open the air valve and port 66-6'? whereby air immediately passes by way of chambers and passages 39, 4I, 42, 43, 44, 12a, I2, I3, 26, 33, to the nozzle orifice 32. This is before any material is admitted to the nozzle orice 32. Then further movement of the piston 6I will then cause its engagement with the head 68 on the valve stern 23 to start the movement of said stem 23 and the material valve 22 from its port 2i, whence the material to be sprayed will flow to the nozzle chamber 25 and thence to the nozzle orifice 32 to be engaged by the air passing to said orice for aerating and spraying said material. The piston 6I will then move back to a position as shown in Fig. 3 wherein the material valve 22 will be widely remote from the nozzle port 2I whereby there is ample passage space between the face of the valve 22 and the nozzle port 2| for free and unimpeded feed of the material to nozzles 24 and To stop operation the operator releases his nnger from the button B whereby the spring 58 will move the air valve part 52 to the position shown in Fig. 2 whereby the ports 55 are closed from the chamber 39 and opened to the atmosphere whereby air in the piston chamber 69 will exhaust by way of the passage 53, chamber 40, port 54, passage 53, in the valve 52, to ports 55, and thence into the atmosphere. The pressure air, however, continues to ow by way of passage 36,

chamber 3S, passages lll, 42, 43, 44, l2a, I2, etc., as aforesaid. The forward movement of the piston Ell permits the spring 'l0 to move the valve stein 23 and material valve 22 forwardly to closing position, and when the valve 22 closes its port 2 l, the piston will still continue to move, the air valve 35 still being open whereby air is still being projected at the air nozzle port or orice 32 to blow oil or cleanse any residual material that might be adhering thereto. Then further movement of the piston ill will eventually bring the air valve 63 to closed position for shutting off further ilow of air to the nozzle capy 3|.

While we have herein described and upon the drawings shown an illustrative embodiment of the invention, it is to be understood that the invention is not limited thereto but comprehends other constructions, details, arrangements of parts, features, and the like without departing from the spirit of the invention.

Having thus disclosed the invention, we claim:

A spray gun for spraying sound deadening and viscous material, comprising a gun body having a nozzle structure provided With spacedly alined air and material nozzles having spacedly alined orifices and each also having a passage of relatively large and ample capacity leading to said orifices at the forward end of said nozzles and having an air passage leading to said air nozzle and to said nozzle orifice for spraying said material thereat, a material valve movable in said material passage for controlling the passage of said material therein and to said nozzle orifice, a valve in said air passage for controlling the passage of air under pressure therethrough, and

means normally spaced from an engageable part of said material valve and engageable with said material valve part and movable by the air passing into said air passage to move said material valve into a remote position to open up the full capacity of movement of material through said material passage to said nozzle orice, said material passage having a chamber and said nozzle structure having a chamber communicating with said passage chamber at one side thereof, and means having a clearance chamber for said material valve at the other side of the material passage chamber for guiding said material valve to said opposite side of said material chamber and into said clearance to make full clearance of the passage of the material to said nozzle chamber.
