Patented July 26, 1938 4UNITED sTATEs PATENT oFFicE 2,124,937 LoWGUN n William S. Whittle, Cleveland, Ohio Application January 8, 1936, Serial No. 58,123
2 Claims.
gun which can be operatively connected quickly and readily to the air chucks of air lines, such as are used in garages, filling stations, and 'similar places, and when so connected can be used to blow out or clean fenders, springs, or other parts of an automobile. f
Another object is to provide a blowgun as specified above, which is of simple construction 'and which embodies means for controlling the passage of air through the gun.
Further and additional objects and advantages residing in the invention and not referred to above will become apparent during the following detailed description of an embodiment of the invention which is illustrated in the accompanying drawing, wherein Fig. l is a side elevational View of the blowgun; a portion of an air line provided with an air chuck that is applied tothe gun being illustrated by dot and dash lines.
Fig. 2 is a view similar to Fig. l. but with the air chuck and air line shown in full lines, the blowgun and air chuck being shown in section taken substantially on line 2-2 of Fig. 4, looking in the direction of the arrows, and the valve of the gun being shown in seated position.
Fig. 3 illustrates an air line and air chuck in elevation with the latter operatively connected to the blowgun which is shown in section, a portion of the chuck being broken away and the valve of the blowgun being shown in unseated position, and
Fig. 4 is an end elevational view of the blowgun, air chuck and air line and is taken looking from the right hand side of either Fig. 2 or Fig. 3.
The blowgun comprises a valve chamber portion I Il and a barrel II extending therefrom. The barrel II is provided with a passage I2 of `reduced diameter adjacent the outer end of the barrel as indicated at I3. The inner end of the passage I2 communicates with a recess I4 formed in the portion I0 and in turn communicatively connected with an enlarged counterbore I5 in the portion I0 by means of a tapered opening I6, the walls of which form a tapered valve seat for a valve later to be referred to. The wall of the counterbore I6 adjacent the outer end thereof is. threaded so that a threaded plug I 'I can be screwed into the portion I0, said plug on its outer end being provided with a reduced partially 5 threaded extension I8. The extension i8 is provided with a passage I9 therethrough that communicates with a counterbored recess 20 in the plug II. The inner end of the plug I'i when it is screwed into the portion I9 bears against a suitable gasket 2I as clearly shown in Figs. 2 and 3.
A valve 22 adapted to seat on the tapered valve seat is carried by the inner end of a plunger 23 that slidably operates through an opening in the portion I0 and has on its outer end an operating button 24. A valve spring 25 abutting the valve 22 and the plug I1 maintains the valve normally seated and in the position shown in Fig. 2, at which time air cannot pass through the blowgun. When the plunger 23 is depressed the valve 22 is unseated, as shown in Fig. 3, and air may flow through the gun.
In order to provide means for operatively connecting the blowgun quickly and readily with an air chuck of an air line a substantially U-shaped spring steel clip 26 is provided. 'Ihis clip is provided in one of its arms with an opening receiving the extension I8 and said arm of the clip is clamped against the outer end of the plug I'I by means of a nut 21 screwed down on the threaded portion of the extension I8. The end of the other arm of the clip is provided with an inturned portion 28 to facilitate the application of the blowgun to an air chuck.
The blowgun can be mounted on various forms of air chucks but in order to illustrate the invention it is shown as operatively connected to an air chuck 29 of known construction, said air chuck 29 being secured to the end of an air line 30 which is connected with a source of compressed air.
The blowgun is applied to the air chuck 29 by inserting the extension I8 into the valve stem nipple receiving opening of the chuck to bring the end of the extension into air sealing engagement with the chuck gasket 3| and to unseat the chuck valve 32, as clearly shown in Fig. 2 and as Will be well understood in the art. In applying the blowgun to the air chuck the spring clip 26 is snapped beneath the chuck body into the position as clearly shown in the drawing and acts to hold the blowgun operatively connected with the chuck with the extension I8 pressing against the chuck gasket 3l and causing the chuck valve 32 to be unseated.
It is evident from the foregoing description that the blowgun can be operatively connected quickly and readily to an air chuck since it is only necessary to apply the chuck to the extension I8 as if it were a valve stem and to snap the spring clip 25 beneath the body of the chuck.
When the chuck has been connected to the blowgun no air Will pass through the latter until the plunger 23 is depressed and the gun valve 22 is moved from its seated position, as shown in Fig. 2, to its unseated position, as shown in Fig. 3. In order to stop the passage of air through the blowgun the operator merely releases the pressure of his thumb upon the button 24, whereupon the spring 25 moves the valve 22 to seated position.
In use the blowgun is connected to the air chuck of an air line, and the operator, while holding the chuck and portion IIJ of the gun in his hand with the plunger 23 extending upwardly, directs the nozzle of the barrel Il at the fender or part to be cleaned and then depresses the button 24 with his thumb to open the gun valve. A strong concentrated jet of compressed air then emerges from the narrow passage I3 of the barrel and impinges upon the part to be cleaned with force sufficient to blow and remove dirt therefrom. When the cleaning has been completed the operator removes the pressure of his thumb from the button 24 and the air ceases to flow through the gun. The'gun canrbe quickly detached from the air chuck and the latter can then be used in its normal manner.
Although a preferred embodiment of the invention has been illustrated and described herein, it will be understood that the invention is susceptible of various modications and adaptations within the scope of the appended claims.
Having thus described my invention I claim:
1. A blowgun comprising a valve chamber portion having an extension adapted to operatively connect said portion with an air chuck so as to unseat the valve thereof, a blowgun valve arranged in said portion, means for unseating said blowgun valve from exteriorly of said portion, a barrel extending from said portion, and means for connecting said portion with an air chuck of an air line with the said extension operatively related thereto andcomprising a spring clip secured to said portion and extending longitudinally away from the same and adapted to pass beneath and embrace the body of the air chuck.
2. A blowgun comprising a valve chamber portion adapted to be positioned on the body of an air chuck and to lie in longitudinal continuation thereof, said portion having an extension adapted when the gun is applied to the body of the air chuck to maintain the chuck valve normally unseated and to place said portion in communication with the interior of the chuck, a valve arranged in said` portion and having associated therewith means for unseating the same which extends longitudinally of said portion and projects exteriorly of one end thereof, a barrel extending laterally from said portion and in communication with the interior thereof and means for connecting said portion to the air chuck with the said extension operatively related thereto and comprising a spring clip secured to the end of said portion opposite to the valve unseating means and extending longitudinally therefrom and passing beneath and embracing the body of the air chuck.
