Definitions

  • This'invention relates to a cooling device for tire arms which in contradistinction to the known arrangements cooling the upper part of the barrel, cools the lower part of the barrel which is hidden in the gunstock.
  • the gunstock which extends at military guns to the front end of the barrel, is provided on its lower part with cooling openings, through which the cooling air passes by way of the perforated guiding tube to the barrel.
  • a sliding cover is provided on the lower part of the gunstock, which covers kand uncovers the cooling openings of the gunstock. In order that this cover should always remain within the length of the fire arm and that the pierced parts of the gun, that is to say the gunstock,
  • the guiding tube and the cover should not be considerably weakened, I provide on the gunstock instead of one continuous opening several openings, soV that for instance by pushing ⁇ foreward the sliding cover the openings of which correspond to those of the gunstoek, all the openings are closed at once. p Thus the fire arm will be entirely closed, by
  • the arrangement set forth above may be completed by a channel situated within the gunstock and connecting the openings of the latter with one another.
  • This channel is advantageously almost as long as the barrel itself.
  • a fixing member for instance a spring controlled'pin or a snap may be applied for fixing the cover in its extreme positions.
  • V Y' ⁇ It is already known to perforate the guiding tube of fire arms having a movable bar- '55 Y y Y* rel in order to cool the latter, but this cooling was effected on parts not covered by thegunstock;v Contrary to Vthis the barrels' offire arms according to thev present invention'vi's cooled on the part covered Vbythe'gun vstock'. 60
  • Fig. l is a side view of the front partof the firearm showing the guiding tube
  • Fig. 2 is a cross section taken on line I-II of Fig. l.
  • Fig. 3 shows the same part of the fire arm as F ig. l but looking from below.
  • the barrel l is slidable in the guiding tube 1 2 provided on its lower part with openings 3.
  • the lower part of the gunstock is "also provided with openings or holes 5 situated ⁇ under the barrel l.
  • a cover 7 having openings 8 is slidably mounted in a guide 6 of the gun stock,
  • the openings 8 of the cover 7 correspond advantageously to the openings 5 of the gun stock and the full parts extending between two ⁇ holes are as long as the holes or longer than the holes, so that when shifting forwardly the cover 7' the openings of the gun stock are closed.
  • the cover 7 can be fixed by a spring con-i trolled pin 9 adapted to snap into depressions 10 or l1 of the cover 7 if the same occupies its opening or closing position.
  • a fire arm having a barrel and a gun stock
  • the gun stock having a channel in its lower part, the lower part of the barrel lying freely in the said channel and being directly exposed to the cooling air of the said channel, the gun stock having apertures in its lower wall communicating with the said channel, and a cover slidable on the gun stock to open or close the said apertures.
  • a fire arm having a slidable barrel, a guiding tube for said barrel and a gun stock, the gun stock having a channel in its lower part, said guiding tube having apertures in its lower wall'and concealed in the gun stock, the lower part of the guiding tube lying freely in the channel, the gun stock having apertures in its lower side communicating with the channel, and a cover slidable on thegun stock to open or close the said apertures.
