BLOWGUN.
Application tiled May 21,
This invention relates to improvements in blow-guns and arrows therefor, and has for its object the improvement of the interior of the blow-gun whereby improved results of blow-guns are obtained by eliminating much of the friction that has heretofore exlsted in such apparatus.
A second object of the invention is to facilitate the manufacture of the gun and .render it' cheaper than similar Aguns heretofore made.
With these and other objects in View which will be apparent as the description proceeds, I will now describe my invention 1n connection with the accompanying drawinvs in which o Figure 1 is an elevation of the gun. Fig. 2 is a sectional view throughvthe gun showing the arrow therein.
Fig. 3 is a cross section of the gun on the line 3-3 of Fig. 1, and,
Fig. 4 is a view of an arrow for use in the v un.
1 denotes the exterior portion of the blowgun barrel which may be made of tin or steel preferably covered with paper which may be wrapped on the blow-gun in layers as shown in 1. I referably coat the exterior of the plalip'er with afinishing varnish, although t 's is not essential.
On the exterior of the blow-gun I form a corrugated section 2 either by corrugating the tube or inserting a corrugated section as indicated in Fig. 2. 3 denotes the shank of 5 an arrow having the usual arrow head and si tion what 1926. Serial No. 110,761.
fibrous attachment 4 at its rear end. This fibrous end 4 preferably abuts against a collar 5 on the shank 3 of the arrow and the fibers are attached in any suitable manner, as for example, as is clearly shown in the 4o patent to IVhite 186,651. The fibers must be suiiicient in volume to completely fill the interior of the tube 1 as shown in Fig. 2.
I have found that the corrugations 2 on the interior of the .blow-gun are of great advantage in combination with a fibrous head such as shown in Figs. 2 and 4, especially when they are of screw-threaded shape as shown in' Fig. 2 and improved result-s are obtained with the corrugated barrel, and bei 5o sides, the corrugations add to the rigidity of the tubes. i
The arrow 3 may be of wood orsteel, the wooden arrow being preferably useful as a toy while the steel arrow may be operated as a weapon.
Having Iparticularly described the invenclaim as new is:
1. A blow-gun comprising a barrel having corrugations on its intherior and an areo row having at its rear a fibrous portion filling the interior of the barrel.
2. A blow-gun comprisinga barrel coated on its exterior with paper and said barrel having corrugations on its interior in como5 bination with an arrow having a fibrous ortion to snugly fit within the corrugatlons on the interior of the barrel.
In testimony whereof I ax my signature.
WILLIAM DE CAVIN.
