9 Claims.

This invention is concerned with a harpoon, it being a general object of the invention to provide a structure which is safe, eective and accurate for the taking of prey where the prey may be approached to a point where an imple- 'ment wielded by the user can be operated to strike the prey.

The device provided by the present invention is such as to be particularly useful and practical -for the taking of large fish, for example, sword fish, and it therefore may be referred to in this connect? on and the device shown and described is particularly suitable for such use. However, it is to be understood that the structure may be used on any form or type of prey whether on land or at sea, and that modifications or variations in the construction may be made as circumstances require.

It is a general object of this invention to provide a structure which involves, generally, a charge carrying barrel provided with a shank and such that it may be manipulated or wielded toward the prey to be taken, and a projectile carried by the barrel and related thereto through means causing the charge to ignite and thrust the projectile into the prey upon the projectile being brought into contact with the prey with pressure such as may be readily generated by the operator.

Another object of this invention is to provide a structure of the general character referred to wherein a hammer is supported by or carried on the projectile. With the construction provided by the present invention the charge is placed in the barrel and is so located that it cannot become ignited or discharged until such time as the projectile with the striking device set has been arranged in a predetermined position relative to the barrel.

Another object of this invention is to provide fa safety mechanism relating a charge carrying barrel and a hammer carrying projectile so that these elements cannot be positioned ready for operation until a safety pin has been applied to the barrel in a predetermined manner and the projectile with the hammer cocked has been applied to the barrel while the safety pin is in place.

The various objects and features of my invention will be fully understood from the following detailed description of a typical preferred form.

and application of the invention, throughout which description reference is made to the accompanying drawings, in which:

Fig. l is a view of a structure embodying the Apresent invention showing .the body carried. on a shank and carrying a projectile ready for operation. Fig. 2 is a side elevation of a portion of the projectile with parts broken away to show in section and showing the safety pin provided by the present invention being employed to set the hammer or striker which is carried by the projectile. Fig. 3 is a detailed sectional view showing a portion of the projectile, with the striker set, applied to the body which is carried by the manipulating shank while the safety pin is engaged with the body enabling the projectile to be engaged with the body ready for operation. Fig. 4 is a View of parts shown in Fig. 3, a portion `of the structure being shown in section and the safety pin being removed so that the mechanism is ready for operation. Fig. 5 is an enlarged detailed sectional View of a portion of the structure shown in Fig. 4. Fig. 6 is a View similar to Fig. 4. showing the projectile operated relative to the body from the position shown in Fig. 4 in such manner as to release the striker and showing the striker fully operated so that it engages the cap of the charge carried by the body. Fig. 7 is a detailed sectional view taken as indicated by line 'I-l' on Fig. 3. Fig. 8 is a transverse sectional View taken as indicated by line 8-8 on Fig. 4. Fig. 9 is a side elevation of the part shown in Fig. 3, being a view taken in the direction indicated by line 9-9 on Fig. 3, and Fig. 10 is a plan view taken in the direction indicated by line I li-I 0 on Fig. 9.

The structure provided by the present invention involves, generally, a body A including a barrel portion Ill and a charge holder II, a carrier` B for the body, preferably in the form of a shaft or rod, a projectile C characterized by a head I2 and a shank I3 which shank has an extension I4 engaged in the barrel ID, a retrieving line D attached to the projectile, a hammer or firing pin E carried by the extension I4, control means F for the firing pin E, and a safety mechanism G characterized, generally, by a stop I5 and a safety pin I6 which elements are cooperatively related to limit entrance of the projectile into the barrel I Il unless the safety pin is in place and obstructing engagement of the firing pin is in place and iobstructing engagement of the firing pin with the charge carried by the body should an attempt be made to apply the projectile to the body with the safety pin in place and the ring pin in an actuated position.

The body A of the structure serves primarily as a mounting or carrier for the projectile and the safety mechanism G and in its preferred form its principal portions, namely the barrel I and charge holder I I, are integrally connected or are formed of a single body of material. As shown in the drawings an elongate tubular element forms the barrel I0 and charge holder II and the plug or closure 20 which closes the inner end of the charge holder II serves as a coupling by which the body A is joined to the carrier B.

The barrel III may be a simple, straight tubular part with a bore 2I fastened or proportioned to slidably receive the extension I4 of the projectile shank I3. In the preferred form of the invention a projecting lip or guard 22 extends from the outer end of the barrel to shield the means F and one or more lateral openings or passageways 23 are provided in the body at its inner end portion or adjacent the point where it is joined to the charge carrier I I allowing free circulation of iuid so that operation of the r- `ing pin is not retarded when the device is operated as hereinafter described.

The cartridge holder II is characterized by a cylindrical side wall 24 defining an opening 28a receiving a cartridge or charge 25 introduced into a position through the barrel I 0. In the preferred arrangement a shoulder 26 is provided in the charge holder at or near the point where the holder joins the barrel I I), the shoulder being such as to receive the flange or ridge 21 provided on the charge 25. In practice the charge 25 may be a body of suitable powder carried in a case such as is employed in a shotgun shell or the like, and a centrally located cap 28 is provided at the end of the charge facing the barrel I il. The charge holder A includes the plug 2U which closes the inner end of the holder and, as shown in the drawings the plug may be threaded into the opening 28a provided in the holder.

The carrier B serves as an element or implement by which the structure may be manipulated and in a typical application of the invention it is a long rod or shaft that enables the user to so manipulate the structure as to thrust the projectile into contact with the object to be taken or pierced by the projectile. In the drawings I have shown the carrier B as a tubular rod closed at its end by ttings 3@ and 3I, which ttings are joined by a safety tie 32 extending through the tubular rod. In practice the rod may be light and in the event that it should fail the safety tie `32, which may be extended to a point to which it is secured, enables the body to be retrieved. In the particular case illustrated the tting 30 of the carrier B is shown joined to the plug 20 by a threaded connection 33 which enables the carrier and plug to be separated when desired.

The projectile C may, in practice, vary widely in form and construction depending upon the service to be performed. In the case illustrated the projectile is shown as having a head I2 with a sharpened tip 34 and with projecting barbs 35. The head is carried by the elongate shank I3 and the extension I4 of the shank is in the nature of an enlargement on the end of the shank remote from the head I 2. In the preferred arrangement illustrated the retrieving line D which, in practice, has one end anchored at or near the operator, is engaged through an opening 40 provided transversely through the shank extension I4 and it is extended forward from the extension I4 to the head I2 where it is made secure or is anchorecl.

The ring pin E is shown as involving a plunger 4I slidably carried in a guideway 42 formed longitudinally in the extension I4 of the projectile, an actuating spring 43 for operating the plunger and a striker 44 projecting from the plunger.

The guideway 42 is a central longitudinal opening or bore in the extension I4 and the plunger 4I is a round element slidably carried in the bore. The spring 43 is a compression spring, preferably a helical spring, under compression between the forward end 46 of the plunger 4I, and a stop pin 41 extending transversely across the forward end portion of the bore 42. At the rear end portion of the extension I4 there are lateral vent openings 48 which occur opposite the side openings .23 in the barrel IB when the projectile is in working condition in the barrel I0. Further, at the inner end of the barrel there is a guide member or wall 49 with an opening 50 centrally located and adapted to slidably pass the striker 44. When the firing pin has been operated to a position such as is shown in Fig. 6 the striker 44 projects through the opening 50 and engages the cap 28. When the firing pin is cocked or set ready for operation the plunger 4i is forward in the guideway or bore 42 so that the spring moves the plunger a substantial distance rearwardly, allowing it to gain momentum before the striker engages the cap 28. In the preferred form of the invention the opening 40 through the extension I4 and passing the retrieving line D is at the forward end portion of the extension and is in communication with the forward end of the bore 42. The line D fits the opening 4I) with enough clearance so that fiuid, either air or water, is admitted into the bore 42 as the plunger 4I is operated rearwardly by the spring 43.

The control F for the ring pin is preferably a spring controlled latch and in the form illustrated it involves a lever type latch carried on a pivot pin 5I in a side opening 52 provided in the extension I4. The4 pivoted lever has an arm 53 with a hook-like head 54 engaged with the rear end of the plunger 4I when the control is set and it has an arm 55 projecting from the exterior of the extension I4 when the control is set. A suitable spring 56 normally yieldingly holds the pivoted lever in a position to catch and hold the plunger 4I in the set or retracted position such as is shown in Figs. 2 and 3 of the drawings. The arm 53' which catches and holds the plunger 4I projects rearwardly while the arm 55 projects in a forward direction and is such as to offer some resistance to inward movement of the extension I4 in the barrel I0. However, when sufcient pressure is applied the extension I 4 will move inwardly in the barrel I9 from the position shown in Fig. 3 and when it does so the arm 55 is depressed, with the result that the arm 53 is disengaged from the plunger 4I. When the plunger 4I is thus released the spring 43 is free to act and force the striker into engagement with the cap.

The safety mechanism G involves two principal elements, the stop I5 and the safety pin I 6. The stop I 5 prevents introduction of the extension into place in barrel I0 except when the safety pin is in place and it is carried by the barrel I@ and is slidably carried in a guideway Si! formed at an angle or so that it is pitched relative to the longitudinal axis of the structure. The angle or pitch of the stop is such that it is pushedout or released by outward movement of extension I4. The stop involves a head 6I which normally extends inwardly and rearwardly into the bore 2i in the barrel I0 while a stem 62 projects outwardly and forward from the head 6|. A spring 63 is carried in a chamber 64 provided in the wall of the barrel ID and is under compression between a stop 65 and a plate 56 that bears on the stem 52. The action of the spring 63 is such as to nor- -mally yieldingly hold the head El in a position where it projects inwardly into the bore 2i of the barrel l as clearly shown in Figs. 4 and 5 of the drawings. When he head 6| of the stop E5 is in its normal position, as shown in Fig. 5, the extension of the projectile cannot be introduced into the barrel IG far enough to be ready for operation since the end of the extension l engages the head 6l in the manner shown in Fig. 5.

The safety pin I 6 has a pin or key-like portion l.) adapted to be slidably inserted in an opening 'H extending transversely through the body A at a point where the barrel l Q joins the charge carrier il. The key portion la] of the pin has a reduced tip portion 'i2 joined to the portion 'iii by a tapered portion 13.

A push rod i5 is slidably carried in a longitudinal guideway l5 provided in the wall of the barrel iii, the guideway 'i5 being located to intersect the transverse opening il and the push rod being such as to normally project down into the openings H. When the safety pin is introduced. into position in connection with the body, as shown in Figs. 3, 9 and l0 of the drawings, the reduced end portion l2 engages under the push rod 'i5 following which the inclined portion i3 pushes the rod l5 up until finally the key portion l@ engages under the push rod. A head on the upper end of the push rod engages a downwardly facing shoulder on the head 5l so that when the push rod l5 is moved up through the action just described the head 9| is retracted from the bore or opening 2| of the barrel it. When the head of the stop i5 is thus withdrawn or retracted the extension le of the projectile may be introduced into the barrel iu until the end te of the extension seats against the key portion lil of the safety pin. It will be apparent that if the firing pin has not been set preliminary to the extension being introduced into the barrel if) the striker t!! will project from the end of the extension in such manner as to engage the key portion 'lil of the safety pin and the operator will feel this engagement and know that the device is not cocked.

To cock the ring pin preliminary to the eiatension being introduced into the barrel iii to the position shown in 3 the reduced extension l2 of the safety pin may be introduced through the opening E@ to engage the striker ifi and depress it until. the plunger ii is caught and held by the control F. The manner in which the safety pin may be employed to cock the firing pin is illusltrated in Fig. 2 of the drawings.

In accordance with the preferred form of the invention the safety pin has a loop shaped handle portion 8o projecting from the key portion 'le and an arm 8l projects from the handle portion im to extend into one of the side openings 23 of the barrel ic when the key is engaged in the opening vl l as shown in Figs. 3, 9 10 of the drawings. The arm 8l is proportioned to slidably or frictionally engage the side of the proiectile extension iii and thus releasably retain the proieotiie as clearly shown in Figs. 1, 9 and l0. When the ring pin is thus in position. or cocked and the proiectile lli is in position ready for use the safety pin is positioned as shown in Fig. 3 and the proiectile is effectively held against displacement from the barrel H3 and the structure can Ibe handled with safety and Without danger of the projectile being struck in such manner as to cause undesired operation of the device. It will be apparent that the device cannot operate under any circumstances until the safety pin I6 has been removed. With the ring pin cocked and the extension I4 engaged in the barrel iii as shown in Fig. 3, the device is made ready for operation by simply withdrawing the safety pin. When the safety pin has been withdrawn the stop l5 is released to project into the bore 2| of the barrel l El and it enters a reduced or undercut portion 9i! of the extension i4. The undercut portion Qii is of such extent as to allow the extension lei of the projectile to move freely inward in the barrel I@ until such time as the control F has been operated to release the plunger t i. As above pointed out, the arm of the control F offers sorne resistance to inward movement of the extension te in the barrel Ill. However, this resista-nce is not such as to prevent movement necessary to effect release of the means F when the head of the projectile strikes the object against which the device is thrust.

From the foregoing description it will be apparent that the charge or cartridge 25 may be readily placed in the charge holder I! by being dropped or introduced into place through the barrel I0. When the charge is in place the firing pin E is cocked by introduction of the safety pin through the opening 5l! in the manner shown in Fig. 2 of the drawings. With the firing pin thus set or cocked and with the safety pin inserted in the opening Il the extension I4 of the projectile may be introduced into the barrel Ill until the arm 55 of the control F is protected by the guard 22 and the end port il of the extension is in engagement with the key portion 7@ of the pin. The safety pin may be left in this position and the device handled freely and with perfect safety until such time as the operator wishes to thrust the projectile into engagement with the prey. At this time the safety pin is removed or disengaged. The structure is manipulated by means of the carrier B so that the projectile is thrust into pressure engagement with the prey in such manner as to cause the extension It of the projectile to move inwardly in the barrel I@ until the control F is released. When the control F is released the plunger ifi is moved by the spring 43 so that the striker 415 engages and operates the cap. When the cap 28 is operated the charge 25 is ignited and the extension lli is driven out of the barrel I 0 and through or into the prey. The retrieving line D being anchored or attached to the projectile is effectively anchored in or to the prey making it possible for the operator to readily retrieve the prey. It is to be observed that 4when the charge is ignited it is directed toward the prey and the force or explosive action of the charge may, in many cases, effectively stun the prey, making it easy to take.
