Abstract

A mechanism for opening a door or shutter to a cartridge that requires synchronization of the opening with the positioning of the cartridge from the loading position to the operating position is shown in the figures. In Fig. 1, a cartridge 1 is shown placed on an elevator plate 2 at the loading or elevated position. Guide pins 3 can be used to locate the cartridge in alignment with the sensing mechanism (not shown) and the opening device which includes a cam key 5. The cam key 5 mates with a slot 6 in the door 7, shown in Fig. 3. Cam key 5 is journaled to the elevator plate 2 and, via a shaft 4, to a slotted bushing 8. Slotted bushing 8 is fastened to a base plate 9. A cam roller 10 operates in slot 11 of the slotted bushing 8 to convert the axial motion of the cam key 5 and its cam roller 10 to a rotary motion.

Cartridge-Opening Device

A mechanism for opening a door or shutter to a cartridge that requires synchronization of the opening with the positioning of the cartridge from the loading position to the operating position is shown in the figures. In Fig. 1, a cartridge 1 is shown placed on an elevator plate 2 at the loading or elevated position. Guide pins 3 can be used to locate the cartridge in alignment with the sensing mechanism (not shown) and the opening device which includes a cam key 5. The cam key 5 mates with a slot 6 in the door 7, shown in Fig. 3. Cam key 5 is journaled to the elevator plate 2 and, via a shaft 4, to a slotted bushing 8. Slotted bushing 8 is fastened to a base plate 9. A cam roller 10 operates in slot 11 of the slotted bushing 8 to convert the axial motion of the cam key 5 and its cam roller 10 to a rotary motion. Spring 12 acts to urge the elevator plate 2 to its load position. Fig. 2 shows the cartridge in the operating position with the spring 12 compressed and the cam key 5 rotated by virtue of the downward travel of the cam roller 10 in slot 11. The door 7, shown in Fig. 3 representing a closure for the opening that provides access to the cartridge, is pivoted open as a result of the connection of the cam key 5 in the slot 6. In operation, the cartridge 1 is placed onto the elevator plate 2, as shown in Fig. 1. The cam key 5 engages the slot 6 of the door 7 (see Fig. 3). Pushing the cartridge 1 downward towards its operating position c...
