Lubricating Patents (Class 86/19)
  • Patent number: 9052176
    Abstract: A device for marking the external perimeter of ammunition. The device includes an outer case with an interior portion which includes a plurality of circular rollers that are position to create a recessed channel for ammunition to be placed into. The outer case is equipped with a crank, which is attached to a spindle, which controls the rotation of the circular rollers. One 360-degree rotation of the crank rotates the spindle and the ammunition. The outer case includes a lever attached to an external side of the outer case. The lever is attached to a holder which holds a plurality of marking instruments. When the lever is depressed, the holder and the marking instruments are lowered on to the external perimeter of the ammunition. While the ammunition is rotated, the marking instruments mark the external perimeter of the ammunition. After marking, the ammunition is ejected through the openings in the outer case which are aligned with the recessed channel.

  • Patent number: 8141467
    Abstract: A bullet sizing and lubrication device for use with reloading presses for improved operation and durability having a sizing die, lube valve, and lube actuator member. The sizing die has a centering portion for centering bullets to be sized and lubricated and at least one lube opening. The lube valve and lube actuator member has a first position where fluid is blocked from entering the at least one lube opening and a second position where fluid is communicated through the at least one lube opening. The principle use is for sizing and lubricating cast bullets, however, other components will benefit from this invention. For example, any number of applications where devices need to be sized and lubricated, such as, shafts and pins will benefit from this application.

  • Patent number: 6912943
    Abstract: A bullet sizing and lubricating device is mountable in an ammunition reloading press to perform bullet sizing and lubricating in one stage with only a single operation of the press lever by using the force generated by the sizing operation to pressurize lubricant causing the lubricant to flow through ports to lubricate a bullet, the device simultaneously performing the sizing of one bullet and the lubrication and expulsion of a previously sized bullet as the bullets are passed axially through the device, the lubricant being pressurized by a piston engaged by a slidably sizing die while a previously sized bullet is retained within a lubricating assembly.

  • Patent number: 5834673
    Abstract: The present invention relates to a method of applying a wear protection substance to the inside of metal cases used for ammunition. The wear protection substance comprises a composition of wax and a solid particle component which has a known barrel wear reducing effect. The wear protection substance is either applied in molten form to the inside of the metal case or is applied in solid form to the inside of the metal case and then melted. The wear protection substance is then spread to form a layer over the inside of the metal case. The metal case is then cooled whereby a solid coating is formed on the insides of the metal case.

  • Patent number: 4893542
    Abstract: This disclosure shows a device designed to facilitate the lubrication of the external surface of a shell casing prior to its being forcibly incserted into a constricting die, in order to be reconditioned for eventual reuse. The device, or shell lubricator, includes a rotatable rigid, cylindrical roller which faces an arcuate, rigid plate. Both of these are faced with a resilient, absorbent material, such as felt, which can hold a lubricating material, to a thickness such that a gap is left between them for the insertion of a shell casing. The shell casings are inserted one-by-one into the shell lubricator, whose rotating cylindrical roller drives them through the gap where they acquire the necessary coating of lubricating material.
