Abstract

A measure for powder such as gunpowder comprises a two part spring loaded frame 1, 2 which can be adjusted to hold a transfer block of various sizes. A reservoir of gunpowder 10 is positioned on the frame to fill the desired loading tube 8 within the transfer block, and transfer block is then moved within the frame 1, 2 to a position over a nozzle 4 which may be placed in the barrel or muzzle of a gun. The spring 12 returns the transfer block to a loading position once the powder has been dispensed. The tension screw 9 can be adjusted to provide the necessary amount of friction to allow movement of the transfer block but retain a powder-tight seal.

SAFETY GUNPOWDER MEASURE

This invention relates to a safety gunpowder measure.

When gunpowder is dispensed from a conventional powder flask several movements are required and the hand is used to grip the flask, representing a risk of injury in the event of an explosion To over come this, the present invention proposes a spring loaded two piece frame enclosing a shuttle block to be moved by the hand and which is provided with a spout that enters the front of a revolver's cylinder or gun barrel The two part spring loaded frame ensures a constant seal and automatically compensates for any wear on the moving parts.

The two part spring loaded frame also allows for the fitting of larger shuttle blocks containing charging tubes of larger capacities.

The nozzle allows gunpowder to freely enter the chambers in the cylinders of antique pattern revolvers without the use of a funnel.

The hand is not around the powder container whilst the firearm is being charged.

Preferably the shuttle block contains a plurality of charging tubes each of differing capacity and is equipped with a spring to automatically return it to battery.

Preferably the powder container is made oftransparent material to show the level of powder, and is provided with a weakening slit or cross in its upper surface to act as a safety valve in the event of ignition.

Preferably the unit incorporates a stand, the front section of which protects the nozzle or spout and houses the return spring guide. The front stand is slotted to assist in the use of a loading funnel in single shot rifles and pistols. Preferably the lower part ofthe two piece frame is provided with a nozzle or spout to provide positive location in the chamber or barrel to prevent powder spillage.

Preferably the fixed sideplate and the movable sideplates have their forward ends curved inwards to grip the loading tube being used.

Preferably the movable sideplate is provided with a gripping piece to assist its forward and backwards movement.

Preferably the fixed sideplate is provided with a gripping piece to assist its forward and backwards movement and in addition has an access hole to assist in changing the loading tubes Preferably the tension spring on the upper end ofthe bottom frame is provided with an adjusting screw in order that the friction between the moving parts can be varied or altered if a larger shuttle block is fitted.

Preferably the shuttle block is so constructed as to enter the two piece frame with the fixed sideplate to the left or right hand side according to preference.

Preferably the upper frame of the two piece frame should be slotted forwards of the powder container in order to visually show that the loading tube is full of powder before it reaches the nozzle or spout on the lower frame.

Preferably the loading tubes should be marked with the amount of powder each can hold.

An example of the invention will now be described by referring to the accompanying drawings Figure 1 shows the two part frame with tension spring and shuttle block return spring according to the invention.

Figure 2 shows the upper and lower frames joined by bolts these being fitted with nylok nuts which by not being fully tightened allow the upper frame to move up and down, the vertical face of the lower frame being slotted for this purpose. Also shown is the shuttle block return spring with its guide block and stud to engage the shuttle block.

Figure 3 shows the assembled unit with powder container but with the movable side plate removed to show the loading tubes, the front one of which being in use.

Figure 4 shows the fixed sideplate.

Figure 5 shows the complete unit with the removable sideplate in position over the loading tubes Figure 6 shows the two piece frame and tension screw without the joining bolts in position.

Figure 7 shows the upper frame with powder viewing slot forward of the holder for the powder container.

Figure 8 shows loading tubes of differing capacity having this capacity marked in grains Figure 9 shows a plastic powder container with a weakening x cut in its base.

In figure 3 a powder transfer block 3 is mounted between the frames 1 and 2; this transfer block or shuttle block contains several loading tubes each of differing powder capacity.

The tube with the desired capacity is placed at the front end so as to be in position under the powder container 10.

The transfer block rests over a stud connected to a bearing block I I controled by a return spring Pushing the transfer block against the spring 12, isolates the loading tube 8, from the powder container 10.

Continued motion causes powder to fall down the nozzle 4.

On the release of hand pressure the spring 12, pushes the bearing block I 1, and transfer block 3 containing the loading tubes 8, back to its starting point where the powder container 10, refills the loading tube with powder.

By removing the the sideplate the front loading tube 8 can be substituted for one of differing powder capacity.

By using a shorter or taller transfer block smaller or larger amounts of powder may be discharged By adjusting the tension screw 9, the degree offriction between the frames may be varied in order to give minimum resistance without powder leakage.
