Application February 10, 1937, Serial No. 124,974
9 Claims.
This invention relates to guards for spray guns.
It is the primary object of the invention to provide a guard for spray guns whereby the spraying of an article may be limited to a certain width and whereby the spreading of the spray beyond the area defined by the guard is obviated.
Particularly it is the object of the invention to provide a guard for portable spray guns, which guard is adapted to engage the longitudinal edges of a strip like article, such as a molding; the guard being urged into slidable gripping engagement with the edges of the molding so that it may be advanced thereon with the spray gun as the;
molding is sprayed thus preventing the spreading of the spray beyond the edges of the molding, and protecting the body on which the molding is mounted.
Other objects and advantages are to provide a guard for spray guns that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation, and facility and convenience in use and general eificiency.
In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and itis also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.
The invention is clearly illustrated in the accompanying drawing wherein Fig. 1 is a side view ofthe spray guard in op-' erative position; and
Fig. 2 is a front view of the spray guard on the molding.
Spray guns are in general use at present for the purpose of applying paint or coating to var- 40 ions articles. It is difficult to prevent the spreading of the spray beyond-the boundaries of the article and to prevent the soiling of bodies adjacent to the article painted. This difiiculty presents itself especially in the painting of orna- 45 mental strips, such as moldings, mounted on the side or wall of a body. In the automotive industry the molding on the body of the automobile is frequently of a difierent color than the body itself. In painting the molding it is necessary to advance the spray gun alongside the molding or ornamenatl strip. Usually the body of the. automobile adjacent the molding is covered with canvas, or paper, or the like in order to protect the body itself from the spray.
55 A spray gun provided with a guard, constructed in accordance with my invention, limits the impingement of the spray to the width of the ornamental strip or molding, without necessitating the covering of the auiomobilebody adjacent the molding. In fact, my guard may be used for spraying any article in such manner as to confine the impingement of the spray on the article to a definite area.
In carrying out my invention I make use of a portable spray nozzle 6, connected by a flexible conduit 1 to the usual mechanism supplying the fluid or paint under pressure.
On the nozzle 6 is placed a guard support or nozzle holder 8, having an elongated slot 9 therein, thru which the nozzle 6 extends. A washer II is disposed on the nozzle 6 on each side of the slot 9. The washers l l are larger than the width of the slot 9 and are held against the respective sides of the support 8, by nuts 12 fastened'on the threaded portion I3 of said nozzle 6. In this manner the nozzle 6 is securely held in the support 8 in various desired, angular positions.
On each end of the support 8 is pivotally mounted a shield M by means of'hinges l5, so that the shields M are in opposed relation and may be swung toward and away from each other. The free edges N3 of the shields H are preferably parallel with the pivot of the hinges l5, and abut each other opposite the nozzle 6.
On the pivot pin of each hinge I is disposed a coil spring H, the opposite ends of which bear against the respective hinge sections so as to urge the shields l4 toward each other. On the support 8 is mounted or formed a handle is to facilitate the carrying and moving of the guard. In this illustration the guard is shown in a substantially cylindrical form, however, the guard may be constructed in other suitable forms.
In operation the edges l6 of the shields H are placed on the opposite longitudinal edges 2| of a molding 22, thereby defining the width of the strip on which the spray issued from the nozzle 6, impinges. The wall 23 on which the ornamental strip or molding 22 is mounted is protected from the spray by the said shields M. The tension of the springs- I1 is such that the molding 22 is gripped between the shield edges IS on the respective mold edges 2i.
U The guard is held by grasping the handle l9 and it is readily advanced on the molding 22 for painting the length of the ornamental strip. The wall or side 23 of. the body is freely protected from the spray at all times. The nozzle 6 may be angularly adjusted in the slot 9 so as to direct the spray to certain portions of the strip in a desired manner. The guard is of sufilcient length to prevent the escapement of the spray thru the open ends thereof, however, it necessary, the nozzle may be boxed in entirely, thereby to define, in all directions, the area to be sprayed.
Having thus described this invention, what I claim and desire to secure by Letters Patent is:
1. In a device of the character described, a nozzle holder, means on the holder adapted to be slidably engaged with an article to confine the spray to a desired area of said article, and means to urge the said confining means to slidably grip the said article.
2. In a device of the character described, a portable nozzle holder, means on the holder adapted to be slidably engaged with an article to confine the spray to a desired area of said article, and means to urge the said confining means to slidably grip the said article.
3. In a device of the character described a portable i'o'r z lea.li older, means. .onLithe holder adapted to engage the opposite edges of .a strip of material'to confine the spray issued from the nozzle on the area between said edges, and means to urge said confining means into slidable engagement with the edges of said strip so as to permit the said confining means to follow the contour of said edges as the device is moved alongside the strip.
4. In a device of the character described, a portable nozzle holder, shielding means on the holder to slidably engage the edges of an object to be sprayed, and resilient means to urge the said shielding means into slidable engagement with the said object so as to define the area to be sprayed.
5. In a device of the character described, a pair of opposed shields, means of connection between the shields arranged to allow the movement of a free edge of one shield toward and away from the corresponding free edge of the other shield; means to urge a shield toward the other so as to slidably grip an article between the free edges of the shields; and sprayer means operatively related to said shields to direct a spray between the shields upon the article between the said gripping edges.
6. In a device for spraying a stripof material, a spray nozzle holder; guard means on the holder for slidably engaging opposite longitudinal edges of a strip of material to confine the impingement of the spray only to the width of the strip confined; and means to resiliently urge said guard means against the respective strip edges to permit the sliding of the guard alongside said strip.
7. In a device for spraying a strip of material, a spray nozzle holder; guard means on the holder for slidably engaging opposite longitudinal edges of a strip of material to confine the impingement of the spray only to the width of the strip confined; means to resiliently urge said guard means against the respective strip edges to permit the;
sliding of theguard alongside said strip; and a spray nozzle being adjustably held in the said holder and being connected to a fluid conduit.
8. In a mold spraying device, a spray nozzle holder, opposed shields pivotally mounted thereon to be swingable toward and away from each other, resilient means .to urge the shields toward each other and into slidable engagement with the edges of the mold, thereby to limit the impingement of the spray to the width of the mold.
9. In a mold spraying device, a spray nozzle holder, opposed shields pivotally mounted thereon to be swingable toward and away from each other, resilient means to urge the shields toward each other and into slidable engagement with the edges of the mold, thereby to limit the impingement of the spray to the width of the mold; and a spray nozzle being adjustably held in the said holder and being connected to a fluid conduit.
