Definitions

  • This invention relates to the cleaning and lubricating of the barrel of a firearm (rifle or artillery piece) by propelling therethrough a projectile which incorporates or has attached to 5 it a cleaning wad which is axially compressed to expel to its peripheral surface the lubricating and cleansing compound with which it is impregnated, so that as the wad passes through the barrel the latter is cleaned of pre-deposited products of 10 combustion and is oiled.
  • the object of this invention is to provide an improved cartridge for this particular purpose and for use in a firearm having a rifled barrel, but not adapted for use as ordinary ammunition,
  • the invention consists 20 in a cleaning cartridge for use in a firearm having a rifled barrel, including a case containing a propellent charge and a projectile fitted in said case, said projectile comprising a bullet or head of a diameter to pass freely through the barrel 5 and having a tail-rod extending into the case and freely slidable through a hollow metal collar or sleeve fitted in the forward end of the case and having a diameter to fit the major diameter of the barrel and engage the rifling, a washer or stop on the end of said tail-rod, and on the tail-rod, between the washer and the collar, a wad or wads of compressible material impregnated with a cleaning and oiling compound of a diameter not less than the major diameter of the barrel, also arranged that said wad or wads are compressed lengthwise to expel the impregnating compound to the peripheral surface thereof when, on propulsion of the projectile through the barrel resulting from explosion of the propel- 40 lent charge, the forward movement of the collar is
  • wads has been used herein to indicate a plurality of comparatively thin discs, but
  • Figure 1 is a perspective View of the complete 55 cartridge
  • Figure 2 a similar view with the bullet and attachments withdrawn from the cartridge case
  • Figure 3 is a view in part section of Figure 1
  • Figure 4 a sectional view showing the bullet 6 and attachments in passage through a rifle barrel, the latter (in part) being shown in dotted lines.
  • the case I is of conventional type having at its base a percussion cap 10 2.
  • the bullet 3 has screwed into its rear end the tail-rod l, terminally fitted with a fixed washer 5, and on this tail-rod are fitted the impregnated felt wads 6 and the collar 1 of suitable solid material (preferably brass) which at its forward end is of the same diameter as the bullet 3 but as its rear end as at 7 is of slightly larger diameter to neatly fit the major diameter of the barrel.
  • the collar is formed with an annular recess 8 and is secured in the case by indenting portions of the case as at 9 into the recess,
  • the wads 6 are impregnated with any suitable compound, and I have found that a small proportion of finely ground abrasive material such as powdered carborundum mixed with gun oil is effective.
  • Cartridges according to this invention are intended for occasional use only, as when a rifle requires cleaning, and in use a cartridge is inserted in the rifie in the usual way, the bullet 3 and leading end of the collar I projecting into the barrel.
  • the resulting explosion propels the bullet, collar and attached cleaning wads through the barrel; when the rear and larger end of the collar meets the rifling its motion is somewhat hindered thereby, but the momentum of the bullet being unhindered carries the washer 5 towards the collar, thus compressing the wads 6 and expressing the clean- 5 ing compound therefrom, so that as the whole assembly of bullet, collar and wads are forced through the barrel the latter is cleaned and smeared with lubricant.
  • a cleaning cartridge for use in a firearm with a rifled barrel comprising a case containing a propellent charge and means for firing it, a hollow collar or sleeve of solid material releasably fitted in the front end of. said case and of a diameter to engage the riflingof the barrel of the firearm, a bullet or head having a tail-rod which passes through said collar or sleeve and is terminally fitted with a stop, and a wad of compressible material impregnated with a cleaning andoiling compound, mounted on said rod between the terminal stop and the collar.
  • a cleaning cartridge for use in a firearm with a rified barrel including, in combination, a case containing a. propellent charge, means for firing said charge and a barrel cleaning projectile fitted in said case, said projectile comprising a tubular collar or sleeve releasably fitted in the front end of said case and having a diameter to neatly fit the major diameter of the barrel, a rod slldable through said collar or sleeve, a bullet or head fixed on the front end of said rod and of a diameter to pass freely through the barrel 0!
  • the firearm a stop on the rear end of said rod, and a wad of compressible material, impregnated with a cleaning and oiling compound, mounted on said rod between the terminal stop and the rear face of the sleeve or collar, said wad being normally uncompressed axially and of a diameter not less than the major diameter of the barrel of the firearm in which the cartridge is to be used.
