This invention relates to improvements in what may be termed a submarine gun for shooting flsh by means of an arrowlike or elongated pointed member which is discharged from the gun by a person while swimming or being submerged un-' der water.

It is a well-known fact that a person swimming under water or submerged in the water can approach within a few feet of any fish that may be present, and because of this fact the fish can be shot and captured by the gun to be hereinafter described. This gun has many essential improvements over the original form of gun which I have used for shooting fish under water. These improvements or advantages may be summarized as follows:

In the original type of gun, using a long tube safety catch-which, after the gun is loaded, can be moved to effectively lock the trigger so that the loaded gun may be left, with the danger being reduced to a minimum of children or others and an elongated pointed member for compressu ing a spring within the tube, the force of the discharge, due to the powerful spring, was so great and the departure of the arrow so rapid that a vacuum was created in the barrel of the gun which retarded and weakened the force of the arrow. To overcome this difiiculty, I have provided a plurality of holes arranged longitudinally of the tube or barrel of the gun, which holes are small enough so as not to weaken the tube, yet large enough to admit water when the gun is discharged. This breaks up the vacuum and overcomes this difiiculty.

Another advantage is that, in the form of gun to be herein described, the pistol grip handle is so placed that when the gun is loaded and being carried while swimming. it is in perfect balance and may be aimed while being held in one hand,

1 allowing the arm of that hand to be stretched outwardly to its maximum distance; this gives added approach to the fish or target. Furthermore, the pistol grip is so constructed that the trigger may be fired by two fingers of one hand, while the grip is held by the other two fingers.

A further advantage is that the gun is provided with a loading catch so constructed and arranged that once the arrowlike member is gripped by it, the arrow can only be discharged by pulling the trigger into releasing position. Afwr the arrowlike member has been locked to discharge position, pulling on the arrow only serves to lock it tightly against the catch, which feature is of great value as it prevents accidental discharge of the gun due to a weak loading grip as exists in guns of this type which I have heretofore used.

A further advantage is that the safety of-the gun is further assured by the use of a thumb accidentally pulling the trigger and discharging the gun. 1

A further advantage is that the gun barrel or tubeis made in two parts, one of which remains with the hand grip. while the other may be removed and the two portions folded up. since the spring will allow this, thereby allowing the gun to be reduced in length for greater ease in carrying or transporting.

These and other advantages will be discerned from a reading of the following specification, taken in connection with the annexed drawings,

Figure 14 shows the two parts of the gun disconnected and folded up for ease in carrying,

- Figure 15 shows a modified form of the extremity of the projectile or harpoon end of the arrowlike member.

Referring now to the details wherein like numbers refer to corresponding parts inthe various views, I and 2 are two tubes which meet at 3 within the two parts 4 and 5 of a hand grip which are arcuately formed at the top portion to receive the ends of the tubes I and 2, thereby forming a two-part combination tube which is grip when these parts are fastened together as by screw studs 9, 'I and 8 which have smooth portions for pivotally supporting parts to be hereinafter referred to.

".The tube 2 is provided with dowel pins 9 and II which enter holes in the grip members 4 and 5 respectively, thereby preventing the tube 2 from turning in the hand grip. Fastened to the tube I, as by a plurality of screws II, is a guide block I2 which is adapted to fit into a slotted portion of the end I3 of the two parts of the hand grip, thereby preventing the tube I from turning in the hand grip members. A set screw I4 carried held in alignment by the two parts of the hand by the block I2 serves to lock the block and the tube I to the two-hand grips, it being understood that the large stem portion of the screw I4 overlaps the two end portions I3 of the h nd grip members 4 and 5.

Each of the tube members I and 2 is provided a safety catch 4| which is pivoted on the smooth part of the screw stud 8. Fastened to the safety catch H is an operating stud 42 which has a shank portion to slidably move in a slot 43 may be operated and the gun discharged. By

holding the trigger in the positionshown in Figure 6 and pushing the thumb nut '44 downward ly, the safety catch 4| is moved to the position shown in Figure 5 wherein the projection 38 and the finger 45 interlock to prevent the arrowfrom being locked into discharging position.

As shown in Figure 11, the tube I is cut away at 49 and slotted at 41 to provide a space for the loading catch 38.

As shown in Figure 13, the end of the cord 24 is attached to the projectile or arrowlike memher by reason of a hole 48 therein. At the end of the projectile orarrowlike member, a harpoon wtih a -plurality of longitudinally spaced holes I5 for the purpose of preventing the. arrowlike member I6, when it is forced outwardly by the spring I1, from creating a vacuum in the twopart combination tube. One end of the discharge spring I1 is formed into a ring and set into a block I8 and is anchored into position by abolt 19 passing through the ring and the block I8, as well as a reenforcing cap 20. The cap 28 has a groove or channel therein to receive a lightspring 2I which is also held in place by the bolt I9. The spring 2I has a conically shaped detent 22 to engage the surface of the tube 2, or preferably a slightly conica1 projection thereon, the purpose of which will be later described.

The tube I carries a reel 23 from which a cord 24 extends. A. support guide 25 for the cord 24 is provided immediately adjacent the reel 23, and a further support and guide 26 is provided at the extremity of the tube' I.

Housed within the two grip members 4' and 5, and pivoted on the holding screw stud I, is a trigger having a slotted arm 21 which carries a end 49 maybe attached as by ascrew-threaded end 58. The harpoon end .of the projectile may be provided with a catch 5| pivoted at 52 and normally held by friction in the position shown in Figure 4, but after the fish has been shot, the catch 5| may move at an angle to the portion 49 to lock the arrow tothe'prey.

I have foundthat with the usual type of projectile end, if the arrow misses the fish and hits a rock, the force is great enough so as to either distort the shaft of the arrow or smash its point, or both, so I propose to insertin the replaced; This construction obviates the trouble pin 28. The pin 28 is adapted to operate in a'- slot 29 in the loading catch 30 which has a pivot hole 3| to receive the smooth part of the screw stud 8. The catch 38 has a slight groove 32 to allow the spring II to pass freely over its end andto better fit around the reduced portion or seat 34 adjacent an abutment 35 formed at the end of. the projectile or arrowlike member I6. The trigger has a finger-engaging portion 36 having an arm 31 extending rearwardly therefrom and having a projection 38 extending at an angle to the arm. To this end of the arm a spring 39 is attached, while the other end is attached to a screw stud 40 which also acts to, fasten previously referred to. y

In order to provide a relatively free length of line to allow the arrow more freedom in its travel after it leaves the gun or tube I, with the least braking action possible. I prefer .to loop the cord 24 back toward the rear of the, gun and pass it under the light spring 2I which sits in arecess as previously described, so it cannot turn around the bolt I9. A slight pull on the cord will cause it to pass free of the projection 22 and allow the projectile to gain considerable momentum before it'has to overcome the resistance of the reel 23. I

In order to more easily load the gun, I pro.- vide a hole 53 in the end of the arrowlike member adjacent the harpoon portion 49, through which hole a pin 51, shown in dotted linesin In Figure 14 I have .shown the two parts I and 2 of the gun disconnected and folded back with the spring I] so that the gun may be placed ,in a short carrying casing.

The gun tubes I and 2 are preferably made of Duralumin-which is strong enough to stand the strain of loading,'yet light enough to be easily carried by an ordinary swimmer. I have found that this is also sumciently resistant to salt water so thatwith ordinary care, such as rinsing with fresh water after several hours use in salt water,- no corrosion occurs. The loading spring l1 and the trigger spring 39'may be made of stainless steel or beryllium to avoid oxidation in saltwater and to reduce care-taking and cleaning to a minimum. All other steel parts are preferably made of stainless steel or plated with a material to reduce rusting to a minimum. While I have shown a loading pin 51, the gun can be reset or loaded without the pin but not so easily. As a matter of fact, the gun can be reset or loaded without the user or swimmer coming out of the water. This can be done by resting the hand grip on the top of one foot while treading water and pushing in the projectile It.

From what has been said, it will be seenthat the various advantages set forth in the early part of the specification are attained through the medium of a rather simple and inexpensive construction, all of which has added greatly to the commercial possibilities of such a device.
