Definitions

  • This invention relates, to whaling harpoons and mere particularly. to improvements in the constructionof that type orharpoon which is designed to be projected from a gun and is fitted with an explosive-charged head.
  • one or more of the pivot pins for the barb elements may be sheared off under the drag loadof the harpooned whale with the result that they may be completely displaced from their supporting head with consequent loss of the whale.
  • the resent invention has. among its principal objects to so improve thev construction of the harp oon as, to obviate the difi iculties and dis-g advantages above mentioned, a specific objectv bleing to provide a construction of the barbed element which cannot possibly swing about its pivot beyond a predeterminedangle, the barbed element as constructed in accordance with. the] present invention including detent means which operate to positively limit the degree of its per-l missible swing outwardly a its support.
  • a further object is to provide, the barb elements and their support with coacting means operative to retain the elements in anchoring position within the harpooned whale even though the pivot pins therefor be completely sheared off.
  • a further specific object of the present invention is to provide these barbed elements which engage the harpoen shaft to maintain the head and shaft of the harpoon in axial alinement durmg its flight toward the target with readily ad-v justable'means for interlockingly engaging the shouldered bosses aforesaid.
  • These means are preferably in the form of axially adjustable screws and are so designed that they may engage the said bosses with exactly the force required to hold the head in Steady axial alinement with the harpoon shaft during flight of the harpoon and yet-permit release of the barbed elements, instantly upon explosion of the harpoon head in,
  • Figure 1 is a view, partially in elevation and.- partially in section, showing the head of the 3 harpoon and a portion of the shaft associated therewith;
  • Figure 2 is a similar view in elevation showing the assembly of Figure 1 as it appears when rotated through an angle of 90 degrees;
  • Figure 3 is an enlarged longitudinal sectional view of a portion of the assembly as shown in Figure 1;
  • Figure 4 is a sectional view taken on the line 4-4 of Figure 3;
  • Figure 5 is a transverse sectional view taken on the line 55 of Figure 3;
  • Figure 6 is a sectional view taken on the line 66 of Figure 3;
  • Figure 7 is an end elevational view of one of the barbed elements as viewed from the line T'l of Figure l;
  • Figure 8 is an enlarged partial sectional view of the screw-equipped end of the barbed element.
  • the present invention relates to a whaling harpoon of the type having an elongated shank or shaft I6 provided at its forward end with an integrally former coupling eye I I.
  • This shank ID of the harpoon is of conventional form, its main body being of cylindrical shape to fit within the bore of the conventional muzzle loading type of gun employed for projecting the harpoon toward its target.
  • the cylindrical shank ID of the harpoon is slotted as at l2 for receiving a slip-ring (not shown) to which is secured the retrieving line by means of which the harpooned whale may be drawn into the whaling vessel.
  • the coupling eye II is provided upon opposite sides thereof with integrally formed bosses or lugs I 3-l3, each of which is provided with a flat seat I4, these seats being disposed in a plane extending transversely of the coupling eye II and normal to the longitudinal axis of the shank I0.
  • the member I5 supporting a plurality of pivotally mounted barbed elements I6.
  • the barb-supporting member I5 is provided with a front end portion I! of generally cylindrical form and with a rear body portion I8 terminating a coupling eye I9, the coupling eye I9 being disposed at right angles to the coupling eye I I and interlocked therewith, as shown in Figures 1, 2 and 3.
  • the body portion I8 of the barbsupporting member I5 is of generally frustroconical shape to provide a supporting surface for the barbs I6, this supporting surface being outwardly flared rearwardly of the member I 5.
  • the barbs I6 are preferably four in number spaced uniformly about their supporting member I5, and in their inoperative position these barbs normally assume relatively inclined positions shown in Figures 1 and 2.
  • the cylindrical body portion ll of the member I5 is provided with four pairs of ears 26-20 uniformly spaced circumferentially about said cylindrical body ii. Each pair of said ears 26-26 receives therebetween the forward end of a barb I6, a pivot pin 2I being projected commonly through each pair of ears and the barb embraced therebetween to pivotally support the barb in position. 7
  • each of the barbs I6 is provided at its forward pivoted end with a freely .extending terminal element 22 which projects inwardly and toward the longitudinal axis of the supporting member I 5 when the barb is in its inoperative or collapsed position, shown in full lines in Figure 3.
  • the supporting member I5 for the barbs is provided with a pair of intersecting passages 23 and 24 therethrough, these passages being respectively in registry with the spaces formed between opposite sets of the paired ears 26-26.
  • the intersecting passages 23 and 24 thus each extend entirely through the body portion I I of the barb supporting member I5.
  • the said member I5 is internally provided with a square depression 25 to provide a pocket, the cavity of which is in communication with the intersecting transverse passages 23 and 24.
  • the depression 25 is so disposed in relation to the transverse passages 23 and 24 that when the barbs I6 are swung about their respective pivot pins 2i into their fully extended positions, as indicated by broken lines shown in Figure 3, the terminal elements 22 of the barbs respectively engage the corresponding side walls 26 of the depression.
  • These side walls 26 of the depression 25 thus coact with the terminal elements 22 of the barbs to limit the maximum permissible outward swinging movement of the barbs I6 and so insure that the barbs will provide secure anchorages for the harpoon when its head is projected into and the cap exploded within the body of the whale.
  • a further important feature of this construction is that the terminal lugs 22 of the barbs I6 operate to engage the side wall portions 26 of the cavity 25 in the head I5 to lock the barbs in the head even in the event that the pivot pins are completely sheared through. In such case,
  • the pivoted barb elements I6 are so uniformly spaced about the member I5 as to provide two 7 pairs thereof respectively disposed in intersecting planes, one pair of said barbs being disposed normally in the plane of the coupling eye I9 of the member I5 and the other pair being disposed normally in the plane of the coupling eye II of the shank or shaft II].
  • the barb elements I6 are all of the same length and of the same general configuration, each being provided at its outer extremity with an inwardly projecting hook element 21 forming a more or less acute angle with the main body portion of the barb element.
  • terminal ends of the hook-like elements 21 are preferably enlarged as at 28 and in the case of the barb elements which are disposed in the plane of the coupling eye I I, each of the enlarged terminal ends 28 is provided with a tapped hole 29 for reception of a set screw 30.
  • set screw 38 may be adjusted to'compensate, for;
  • the harpocn of the present invention is provided with the conventional spear-headed cap 3!, which is provided with an internal cavity 32 for receiving the explosive charge.
  • This cap is threaded, as at 33, upon the forward end of the head i5, and the latter is provided with a longitudinal bore 3% (see Figure 3) into which is threaded a detonating fuse (not shown).
