Definitions

  • the invention relates to a rocket projector having a magazine containing the rockets, a loading chamber with adjoining firing tube, and-means for the automatic feeding of the rockets from the magazine into the loading chamber.
  • a rocket projector comprising in combination: a magazine adapted to contain the rockets, a loading chamber having an adjoining firing tube, a feeder drum uniformly rotated when tiring a series of rockets and moving the said rockets from the said magazine into the said loading chamber, a spring-loaded closure flap operated by the rockets entering into the said loading chamber and cooperating with special closure faces provided on the said feeder drum in shutting olf the said loading chamber during the firing, a carrier shiftably mounted in the said magazine behind the last rocket contained therein, belt drums in driving connection with the said feeder drum, and tension belts adapted to be Wound on and o the said belt drums and attached to the said carrier, imparting to the latter the feed required for conveying the rockets into the said feeder drum.
  • a free-wheel coupling may be interposed advantageously in the said driving connection from the said feeder drum to the said belt drums.
  • Fig. 1 is a cross section along line I-I of Fig. 3 of a rocket projector with the magazine partly filled,
  • Fig. 2 is a part cross section on the line lI-II of Fig. 3,
  • Fig. 3 is a longitudinal section of the feeder drum on the line III-III of Fig. 1,
  • Fig. 4 is a longitudinal section of a 4belt drum on the line IV-IV of Fig. 1,
  • Fig. 5 is a section on the line V-V of Fig. 3,
  • These sections are formed each bytwo equal tubular segments 14 arranged symmetrically With respectv to their longitudinal axis, and b-y the Walls 12 xedperpe'ndicularly at theirends.
  • the exterior surfaces of the tubular segments 14 (see Fig. 2) will be referred to hereinafter as closure surfaces 15, and the narrow surfaces of the side walls 20 and of the partition walls 12 (see Figures '3 land'2), parallel to the longitudinal aXis of the feeder drum, will be referred to as control surfaces 17 and 18.
  • closure surfaces 15 the narrow surfaces of the side walls 20 and of the partition walls 12 (see Figures '3 land'2), parallel to the longitudinal aXis of the feeder drum, will be referred to as control surfaces 17 and 18.
  • These control faces of the individual walls 12 and 20 are formed symmetrically with respect to the longitudinal axis of the feeder drum.
  • a control face is formed by two portions, namely a circular recess 17 (Fig.
  • the feeder drum may accordingly be driven either from the motor 29 (Fig. 3) or through a hand crank 33 adapted to be mounted on the shaft 32.
  • Beltdrums 35 (Fig. 3), on which the belts 11 are wound, lare rotatably mounted on the' cylindrical connecting pieces between the discs 21 and the kend-,walls 20 of the feeder drum.
  • the pins 36 Only when the feeder drum is turned in the direction required for the ring, the pins 36 resiliently mounted in the end-walls 20 serve for carrying along the band drums 35 in that they abut semi-circular faces 37 (Figs, 6, 7) of the latter. With the feeder drum rotating in the opposite sense the ends of the pins cannot drive the belt drums; they run up ramps 38 to the highest points 39 thereof, from where they are pushed back by the springsV 41 to the bottom of the ramps.
  • a ap subdivided into various sections 45a vto 45e is pivotally ⁇ mounted on axles 44 parallel to the longitudinal axis of the feeder drum 3.
  • the ap sections 45a, 45h, 45C consist of lids 46 (Fig. 2) with substantially circular arc shapedclosure faces 47 adapted to the shape of the rocket bodies.
  • vf'lhe'lids which extend over the full length vofY thesections, are subjected to the bias of springs 48, and'
  • An additional rib 53 (Fig. 2) arranged at the end of the rearmost flap section 45e restrains the rockets 7 during their" feeder movement into theloading chamber 4, by engaging into annular grooves 55 (Fig.
  • the interstices formed between the Walls 12 of the feeder ⁇ drum 3 are engaged by ribs 64 attached to the casing (Fig. 3), on which also slider and guide tracks 65; (Fig. 1) forthe rockets are arranged.
  • the guide tracks as, well, as tracks 66 connected to the casing cover together form a duct 67 through which the rockets are further conveyed to the loading chamber 4 after having emerged fromA the magazine 1.
  • the center line of the. conveyer duct ⁇ 67 runs originally in the same directonat ⁇ which the rockets ⁇ emerge from the magazine, and sub-., sequently ina direction inclined to the first one ⁇ at an acute angle,
  • the ⁇ axis f the loading chamber 4 which is ⁇ designed for ⁇ receiving the rockets before the firing, is determinedV by the centers of the portionsof semi-circular cross section.
  • f f ull length'of the casing is co-axially adjoined forwardly by the ⁇ starter tube 5 (Fig. 3), and rearwardly by a current ⁇ (not ⁇ shown).
  • the rockets (Fig. 1) are pushed by the carrier 6 outV ofthe magazine into the duct 67 with a speed depending,v on the rotational speed of the feeder drum. There the,l actually foremost rocket is forced by a spring loaded; bolt 73 and by a lever S9 intoa recess 17 of the feeder drum 3is accelerated by the latter and is guided further.'
  • the aps 45a, 45b, 45C protruding into the feeder duct67 are pushed out of their rest position by the rocket directed towards the ⁇ loading chamber.
  • the rocket As soon as the rocket lies completely in the loading chamber it is autofV matlcally primed in that its two contact points come into ⁇ contact with ⁇ the contact pieces 70 arranged in theloadmg chamber.
  • the flaps 45a, b, c swing bythe action of ⁇ the springs 48 again into the feeder ducttheir closure faces 47 ⁇ hugging the rocket.

  • the re-loading of the magazine (Figs. l-2l5) is effected by pushing the rockets into the recesses 17 of the feeder drum 3 through the aperture 74 of the casing wall 72, and by turning the feederdrum by the aid of the hand crank 33' in the rotational sense Opposite to the feeder movement when ⁇ firing.
  • the rockets can be inserted, when the feeder drum is in a position as illustrated in Fig. l5, ⁇ into which the feeder drum has to be turned back prior to the beginning of the 1re-loading.
  • the portions 18 of the control faces of the feeder drum come into contact with the tubular carrier 6, and ⁇ force the same towards the magazine.
