The present invention relates to a spraying apparatus, and more particularly to a moistening gun for a spraying device particularly adapted for moistening fabric.
In the ironingof clothes and the pressing of fabrics it is necessary to have the clothes or fabric slightly damp. Generally the necessary amount of dampness is applied to clothes which have been dried, by a sprinkling, spraying or moistening device. Where clothes and fabrics are to be ironed or pressed shortly after the meistening or dampening process, it is extremely mportant to have the moisture applied in an extremely finely divided form so that no appreciable drops of moisture produce excessively wet areas. Particularly in the case of laundries, pressing establishments, and wherever large amounts of material are to be handled, it would be desirable to provide a relatively simple to operate and inexpensive to manufacture spraying device or moistening gun.
In accordance with the present invention a relatively simple device is obtained having a minimum of movable parts and which nevertheless projects a spray substantially in Vapor form` Numerous embodiments may be added including a moistening device rigidly secured to an iron, goose, or the like.
It, therefore, is an object of the present invention to provide an improved relatively simple moistening gun.
It is still another object of the present invention to provide a convenient to use light-weight spraying device for use in moistening fabrics which are to be ironed or pressed.
Still another object of the present invention is to provide an improved combination of an iron or pressing means with a selectively operable moistening device.
Other and further objects of the present invention subsequently will become apparent by reference to the following description taken in connection with the accompanying drawings wherein:

' Figure 10 is a cross sectional View of a portion of the device shown in Figure 9. j
Referring more particularly to Figures 1 to 5 it will be seen that there has been shown a pipe I2 which is connected to a suitabe source of uid under pressure such as water, and which pipe iS provided with a T-connection I4 which in turn through suitable coupling means is connected to a shut-off valve I6. The shut-olf valve I6 is connected to a ilexible conduit or tube I8 connected at an intermediate point to one end of a spring 2S, the other-end of which is connected to a suitable overhead support. The other end of the flexible conduit i8 is connected to a moistening gun 22 having a body 24, a handle 26 and an operating triggerl or control member 28.
IThe handle 2S is secured to the body 24 by suitable fastening means such as a screw 3B. At the forward side of the handle 2S there is provided an adjustable stop member 32 which is arranged to act as a limit for the movement of the trigger member 28. lThe trigger member adjacent its upper end bears against a shaft collar 3 mounted at an intermediate point on a reciprocable conduit 35 which is in fluid communication with the flexible conduit I8. The body 24 adjacent the trigger 28 is provided with a suitable recess to accommodate the trigger and the collar 34. In addition a spring 38 is arranged between the collar 311 and a portion of the body 24 so as to bias the reciprocable iiuid conduit Sii toward the forward portion of the body 24. At the front end of the body 24, as may more readily be seen in Figures 3 and 4, there is a forward body member 43 which threadedly engages the main body 24. Adjacent the forward end of the reciprocable tube 35 there is threadedly mounted a whirling spray unit 42 which is shown in perspective in Figure 5. The spray unit G2 has a threaded portion d4 of relatively small diameter so as to engage the inner threaded surface of the end of the conduit 36. Adjacent the threaded portion there is a cylindrical portion 45 having oppositely arranged attened areas 48 and 58. Separated from the portion 4% by a recess 52 is a spray head 54 of similar diameter. The spray head 54 is provided with two slots 5S and 58 arranged at opposite sides so as to be at angles to each other. The spray head 54 of the spray unit 42 has a recessed portion which carries a resilient sealing member 60.
The body portion 4D is provided with a coaxial recess 62 having interior threads adjacent one end thereof as at 64. At the bottom of the recess 62 there is positioned a biasing spring 36 which is arrangedto act against a packing member consisting of a resilient rubber-like annular ring 68 mounted between two metal washers or rings 10 and 12. A nozzle 14 having an axial discharge orifice I6 is threadedly mounted to engage the threaded portion 64 of the body 40. The nozzle 'I4 has a coaxial bore 18 of a diameter substantially equal to the diameter of the spray unit 42. The spray unit 42 is shown in Figure 4 in the position when the lever or trigger 28 of Figure 2 has been moved rearwardly against the stop 32 so as to withdraw the sealing member fill from the orifice 16. Fluid within the conduit 35 passes through a pair of openings ll arranged just above the internally threaded end of the conduit 3S. Fluid passing through the openings 80 then passes past the portion c of the spray unit 42 over the flattened areas 43 and 5f! thereof. The fluid thereupon circulates in the annular recess 52 and thence passes through the angularly related slits 56 and 58 so as to be discharged within the chamber 18 of the nozzle 74 in two relatively flat streams at angles to each other. This action of the fluid under pressure in the nozzle 14 causes the fluid to be projected through the orifice I6 in the form of a whirling relatively fine mist or fog. In order to cause the apparatus to spray it is only necessary to actuate the lever 2S which reciprocates the longitudinal conduit 36 a sufficient amount to withdraw the sealing member a?! from the orifice 'i6 of the nozzle M. From the foregoing it will be appreciated that the `mechanism provided is relatively simple to manufacture, is light weight, and yet operates to produce improved results for the purpose intended. In spite of the fact that the number of actuations of the trigger in the apparatus of this kind might be appreciably greater than in other spray gun apparatus, the relatively simple structure is such vthat a minimum amount of maintenance and .repair will be required.
Another form of the present invention is disclosed in Figures 6, 7, and 8 which merely has a body which serves both as a handle and a body. Thus the arrangement in Figure 6 has many of the elements which correspond exactly to the elements in the foregoing figures, and hence corresponding parts will be given similar reference characters. The body 25 is modified slightly to accommodate the trigger 29 which is arranged to have a member 3| pivoted thereon for engagement with the collar 34 on the reciprocable conduit 36. The adjusting screw 32 is directly mounted upon the body 25. The remaining elements are in the same relation and identical to corresponding parts shown in Figures 2 to el inclusive, The device is grasped by the hand and pressure applied by a squeezing Vaction to actuate the lever 29 thereupon to reciprocate the conduit 35 sufficiently to open the discharge portion. in the nozzle 14.
`Another arrangement is illustrated lin Figure 9 which shows the invention used in combination with a sad-iron or electric flat-iron 82 having a handle 84. The handle 84 of the conventional structure has a rcd extending therethrough which rod is usually secured to the upright support members '86 and =88. In place of the rod mentioned, there is provided a conduit which is connected to the flexible conduit I8. The conduit 90 serves to retain the handle portion 84 between the upright supports 86 and 88 and extends forwardly to support on an extension thereof the body 23 of a member otherwise generally corresponding to the apparatus shown in the previous embodiments. The principal difference in the construction of the body 23 however is that the lower portion has a fiuid conduit B which supplies liquid in back of the spray unit 42 whereas in the previous constructions the liquid was Supplied through a hollow member or conduit 36 through port openings 8D. In the present instance the former conduit is replaced by a solid reciprocable rod 92 which has its uppermost end supported in an adjustably positioned cap-like member 94. A suitable hand lever 96 is pivotally mounted in the body 23 so as to be readily accessible by operation by one finger of the hand which is grasping the handle 84 of the flat iron or goose. From the position shown in Figure 9 it will become apparent that it is possible to project just ahead of the nose of the iron a spray so that for finishing work for example just the adequate amount of moisture may be applied to straighten out difficult wrinkles, and where a similar arrangement is applied to a tailors goose adequate moisture may be selectively supplied for the pressing and shaping operations.
While for the purpose of illustrating and describing the present invention, certain preferred embodiments have been disclosed in the drawing, it is to be understood that the invention is furthermore susceptible of such variations as may be commensurate with the spirit and scope of the invention defined in the following claims.
