Abstract
A powder measuring device for use in connection with reloading cartridges has a powder transfer member supported for translating or, alternatively, rotating between a position where at least one cavity in the member is filled with powder from a hopper to another position wherein the powder is discharged through a tube to an empty cartridge. A cartridge to be reloaded is driven upwardly by a manually operated ram. The force for actuating the mechanism that drives the transport member is transmitted through the cartridge which means that unless a cartridge is positioned on the ram for receiving the powder the transport member will not be moved in response to operation of the ram and unintended discharge of powder will be prevented.
Claims11
A device for measuring the quantity of powder that is inserted in a cartridge in a reloading apparatus having means for driving the cartridge in alternate axial directions and having a support for the device, said device comprising:
- an adapter for being mounted on said support and having an axial bore,
- a tubular element in the adapter bore, said element subject to being driven in one axial direction in said bore by a force transmitted through a cartridge being driven into said bore in alignment with said element,
- a body supported from said tubular element outside of said adapter,
- a powder transport member mounted for moving on said body, said member having at least one cavity corresponding in size to the quantity of powder desired in the cartridge, said cavity being located for being loaded with a quantity of powder when said member is in one position and for discharging said quantity through said tubular element into said cartridge when in another position, and
- drive means engaged with said transport member and responsive to said tubular element being driven in said one axial direction by said force transmitted through a cartridge by driving the transport member alternately between cavity loading position and cavity discharge position.
A device for measuring the quantity of powder that is inserted in a cartridge in a reloading apparatus having a ram movable within predetermined limits for driving a cartridge in alternate axial directions and having a support for the device, said device comprising:
- adapter means for being mounted on said support and having an axial bore,
- a tubular element in the adapter bore, said element subject to being driven in one axial direction in said bore by a force transmitted through a cartridge when a cartridge is mounted on said ram,
- a body mounted on said tubular element and having a generally planar surface extending transversely to the axis of said tubular element, said body having a powder discharge hole through it aligned with said tubular element,
- a powder hopper mounted to said body and having an output port spaced from said generally planar surface,
- a powder transport member disposed between said port and said surface and movable on said surface, said member having a plurality of through-holes constituting cavities for transporting powder from powder loading position next to said port to discharge position aligned with said discharge hole,
- guide means for constraining said transport member to move linearly to thereby hold a selected one of said cavities on a linear path between said port and said powder discharge hole when said member is in one orientation on said surface and to dispose another of said cavities on the same linear path when said member is in another orientation on said surface,
- said transport member having a plurality of notches presented toward said surface,
- lever means having one end swingable on said adapter and another end engaged in a predetermined one of said notches when said member is in one orientation, said lever means having intermediate of its ends a pivotal connection to said body such that when said tubular element and body are driven under the influence of a cartridge said transport member will move and shift the cavity on the linear path from loading position to discharging position, and
- spring means engaged with said lever means for returning said transport member to loading position when the ram is retracted to take the cartridge out of driving relation with said tubular element.
