I CAR WASHER GUN Filed Nov. 9, 1929 2 Sheets-Sheet 2 0J w Y@ Parent eng. 1s, 1932 PQRATION GE DELAWARE Application med November Uur invention relates to appliances for projecting 'either air or liquid in a stream, snd

for intermingling nir in varying proportions with the liquid before the liquid is emitted, so as to otornize the liquid into sprays oi varyv ingspreeds end densities.

. quentities.ot1 esc enerslly speaking, the objects oi our invention include those voi roviding an applinnce of 'this class in iv ich theV proportions of the water und air can readily be varied, so that the projected duid cen veryifrom mere eir end from e solid stream of liquid to sprays in which the proportion ot the ein to the li uid may ronge up to equal all, and in which the selected proportioning con readily be maintained While the appliance is being manipulated in various directions.

ln enother aspect, our invention provides an applience oi this class having the eneral shape oi a gun, end having the nee ed sir and liquid connections at the reer end of the stock ci the gun, so that the weight of portions ci the air hose and the liquid hose will help to balance the appliance when in use. Furthermore our invention aims to provide an appliance of this class having a Huid-emittin barrel for accuratel directing the projecto fluid or mixture of uids; and also having the liquid controlled by rotational movements oi the barrel, together with simple and easily manipulated means for latching the barrel against movement and for sealing it to the body of the appliance. l

More particularly, our invention aims to provide a fluid-projecting appliance of this class in which an air tube retains the valve seat for the liquid-controlllin`g barrel in its normal position, so as to obviate the need of auxiliary fastening elements; and in which this barrel is sealed to the body of the appliance by a part of the same means which secure-the barrel in adjusted sition, and in which the air valve mechanism is disposed for convenient operation and can readily be SIGNORE T0 BINXS MANUFACTURING" oFFlcE .r r BMSEN, mitm EERSLEB, AN D FRITZ WHLEN, OF CHICAGO, ILLINQIS,

In one of its immediate commercial opplications, the appliance ot' our invention is articulerly suited for use in dusting fn? in washing automobiles, railway eers or other vehicles'. Hence we are illustrating our ini illustrating it in a form shaped after the geny eral manner of a. gun, with the body 1 dis# posed at an oblique angle to the stockl or handle 2, and with 'the air-controlling trigger 3 underhan ing the juncture of the handle with the bo y, since this general formation facilitates the convenient manipulating and accurate directing of the appliance without unduly tiring the user.

The body 1 andthe handle 2 desirably form4 a single-piece casting, which is cored to afford an air passage 4 and ali uid passage 5, both of which passages extend longitudinally of the handle or stock 2 from the rear end of the latter to points adjacent to the juncture of the handle with the body. The rear ends of both passages are desirably threaded, so that an air hose 6 (to which compressed air is suppliedfrom any suitable source) can be connected to the air passage 4 b a nipple 7, and so that a water hose8 can be connected by a threaded fitting 9 to the'liquid passage 5.

The body 1 has a longitudinal bore extending for part of the length of the body from the forward end of the latter, and this bore comprises three portions, namely: a forward end portion H provided with an internal thread, a more rearward portion M and an interposed portion K which is' smaller in diameter than the said bore portions H and M. fIhe rearward bore portion M terminates. considerably forward of the juncture of the` body 1 with the handle, and the rear end portion of the body includes a hub 10 projecting forwardly into the said rear bore portion M coaxial with the bore of the body.

The part 11 of the body rearwardly of the rear bore portion M has an air duct 12 also coaxial with the body of the bore and opening into the lower portion 13 A (Fig. 5) of a valve chamber formed in the said juncture of the body and handle parts. This chamber portion is generally cylindrical and desirably has its axis in the common central vertical plane of thesaid handle and body parts. The rear body part 11 also has a crescent-sectioned liquid duct 14 connecting the rear bore portion M through two passages 15 (Fig. 8) with the liquid passage 5 in the handle.

Extending upwardly into the valve chamber is a detachable valve body which includes a shank 16 threaded into the body member of the appliance, a lower head 16 A at the lower end of the valve body (whereby the latter in? be rotated to attach or detach it) a stem 16 of smaller diameter than the shank 16 and the bore of the valve chamber 13 A, and a-valve head 17 at the upper end of the valve body. The upper portion 13 B of the valve chamber is of smaller diameter than the lower portion 13 A, and is connected' to the latter by an annular shoulder 13 C on which the upper end of the valve head 17 seats.

The valve body has an axial bore 18, and the upper ortion 18 A of this bore is enlarged in diameter and is connected by radial ports 19 Fig. 8) to the annular space between the ore of the valve chamber 13 A and the stem 16 B of the valve body. Extending slidably through the bore 18 of the valve body is a stem 2O of the movable air valve member, whichmember has an enlarged valve head 21 adapted to seat on the upper end of the bore of the valve body, and also has a stem 22 projecting above the said valve head. This stein centers a compression spring 23 which is interposed between the valve head and the upper end of the valve chamber portion 13 B, and which spring continuously tends to seat the valve head.

The valve stem 20 extends downward below the gunV body and has its lower end disposed for engagement by the back 24 of the trigger which has two arms 25 extending at movement of the trigger' away from the air valve, the pivot pin being detachably secured in osition of a spring cottefi` 41.

Exten ing forwardly from the interior hub 10 in the gun body coaxial with the bore portion K of this body is an air tube 28 which has its forward bore portion 29 A of smaller diameter than thememaining portion 29 of its bore, so as to accelerate the velocity of the air which issues forwardly from this air tube. The rear portion 28 A of the air tube is of reduced diameter and is threaded into the forward end of the air duct 12, and-the juncture of the differently diametered portions of this tube aiord an annular shoulder 28 B for engaging a ackirg washer 30, desirably of a materia una ected by water.

Bearing against the rear face of this washer and slipped over the smaller dametered air tube portion 28 A behind the washer 30. is a valve seat 31 which desirably is of a compressible material and which extends radially beyond the washer, this valve seat being clamped in position by a seat-holding cup 32 which is threaded on the rear portion vof the air tube.

Extending rearwardly througlh the small diametered bore portion K of t e gun body and threaded throu h that bore portion is a gun barrel 33 whic has its rear end in engagement with the valve seat 31 when the supply o f liquid to the bore of the barrel is shut off as in Fig. 2. This gun barrel extends slidably and rotatably through an an. Iiiular packing ring 34 which is normally what larger than the outside diameter of the gun barrel 33, so that the barrel will not bind 1n the bushing to interfere with the compressing of the packing ring 34 by this bushing, the bushing being threaded into the forward end bore portion of the gun body.

The gun barrel also desirably extends for a. considerable distance forwardly beyond the forward end of the air tube 28, and this barrel preferably has three bore portionsof different diameters, namely: a rear bore portion 33 A considerably larger in diameter than the air tube and extending forwardly beyond the air tube, an intermediate bore portion 33 B of somewhat smaller diameter than the rear portion 33 A (in which intermediate bore portion the liquid and the air intermin'le), anda frontal discharge-portion 33 of still smaller diameter but def sirably also of considerable length in proportion to its diameter. n

In using such an a pliance for washing a car, vthe barrel may rst be screwed tightly against the valve seat 31 (as shown in Fig. 2) and clamped in position by screwing the bushing 35 rearwardly of the appliance to compress the packing ring 34. The rearend of the barrel then acts as a valve to shut 0H the supply of water to the barrel from the assages 14 and 5, when th'e water hose 6 is connected to a convenient faucet.

When our washer gun is then held after the manner of a pistol, an upward pressure'on the trigger will open the air Valve and cause the compressedair (supplied through the air hose 8) -to issue from the barrel. Since the long bore of the barrel directs the issuing air accurately, and since the direction can readil be sighted by the user (as in usin ak pistol7 the resulting stream oi air is easi directed in a concentrated stream against irt which has lodged on the car, or the air can be emitted in the forni of widened s reads according to the extent to which t e trigger is manipulated. f

After the accumulated loose dust has thus v been blown on', a releasing o the upward down o n the packing ring, thereby-clamping' the barrel in a position in .which it affords a xpassage of .predetermined sizes past the liquid valve seat 31, so that a solid stream of water is `projected from the barrel.

Upon pressing the trigger di tally up ward, compressed air is alsoadmlgtited to the air tube 28 and rejected i nto the intermedi; ate portion 33 of the bore of the barrel, which bore portion aords ay mixing chamber for the water and the air. With this intermediate portion relatively4 long in proportion to its diameter, as shown in the drawin an intimate intermingling of the air wit the water is 'readily secured, and the pressure of the compressed air also aids in projecting the resulting fluid mixture for considerable distances. f

Moreover, this fluid. mixture is increased in velocity while passing through the smaller diametered discharge portion 33 C of the bore of the barrel, so that it has a forcible tendency toward 'expanding after it issues from the barrel. Consequently, the user can readily secure a. thoroughatomization of the water, and likewise can readily vary the ine, ness of the atomization by .mere manipulations of the trigger and the gun barrel.

In practice, we have found that such a car Washer can be used effectively with water supplied at widely varying pressures; as for example, equally well with a twenty pound pressure from a faucet in a garage, or at no pressure at all when the water hose depends into a water tank so that the water is siphoned up by the suction of air passing through the barrel. By providing the air and water con'- nections at the rear end of the handle, we

permit the weight or the connecting hose portions topartially odset the leverage of the -gun about the hand of the user, thereby mak.- ing it easy for a user to manipulate our appliance'even though the greater portion of the length of the appliance is forward of the hand grasping the handle behind the linger stop 42 on the handle.

lin case the appliance should clog, or when new packings are needed after prolonged usage, the barrel and the packing ring 34: can readily be detached after unscrewing the packing bu hing 35, thereby leaving' the air tube projecling forwardly beyond the gun body. This air tube can then so as tol withdrawV itfrom the body along with the liquid valve seat 3l and the parts between which that seat is clamped.

So also, when the pivot pin 26 is4 detached after merely removin the cotter pin, the trigger slips od the gun ody and the entire air valve mechanism can then be detached by merely unscrewing the air valve body. After this has been done, a detaching of the hose fittings 7 and 9 exposes the rear ends of both e unscrewed;

of the fluid supply passages and permits the stripped body member 'of the appliance to be dipped into a cleaning liquid, so thatthe entire operation of disassembling and cleaning our appliance is a simple and s edy one.

By employing the inner en of the barrel as part of the means for regulating the supply of liquid, we obvia-te the need of a separately operable valve for that purpose. And by arranging the bushing 35 and the compressible packing ring as, above described, we enable this packing ring to serveboth as the means for preventing movement of-thebarrel with respect to the gun body and for sealing the barrel to the gun body against a leakage of liquid. So also, by threading the barrel to the gun body (instead of having the barrel slide in an unthreaded bore portion of the gun body) we can secure quite fine adjustments for the supply of liquid, since even an entire rotation of the barrel will only move the latter longitudinally of the gun body by the pitch of the thread.

In practice, we desirably make the bore of the packing-compressing member 35 somewhat larger than the outside diameter of the barrel, thereby permitting the barrel to tilt into alinement with the air tube when screwed up against the valve seat, as a limited amount of such tilting willbe permitted-by the ordinary machining of the thread on the barrel and in' the body bore portion 'K. Since the compressed packing 34 seals the barrel to the body, the just mentioned threading can be sufficiently loose to permit an easy manual rotation of the barrel when the compressing nipple 35 is loosened, as we do not depend on he said threaded connection for a liquid sea Y By coringthe liquid and air passages in the body after the manner here disclosed, we can employ a single casting for the entire body member and one which requires very little and simple machining. And, since the air tube and seat unit, aswell as the air valve unit are readily attached as units to the body of our appliance, the entire assembling is quickly effected. y

By providing the barrel with a long discharge bore portion 33 C spaced considerably forward from .the outlet end of the air tube we permit the user to project a concentrated and solid stream of either air or water for considerable distances, thereby making our appliance highly eiicient for cleaning rather inaccessible portions of a car or the like. Since both the stock of the body member and the clamping nipple 35 only need to project slightly above the barrel, the stock and nipple do not interfere with an accurate sighting of the direction, thereby enablin the user to avoid a waste of both water an air.

However, while we do not wish tobe limited to the conjoint employment of the various novel features of our invention. Nor do we wish to be limited to the details of the construction and arrangement as heretofore described, since many changes might be made without departing either from the spirit of our invention or from the appended claims.
