Photographic camera and flash assembly

In a photoflash assembly of the type wherein (a) a plurality of flashlamps are movable sequentially to a firing position, (b) each of said flashlamps has at least one exposed lead segment, and (c) said assembly is adapted for attachment to a camera having a firing circuit for igniting a flashlamp in the firing position, the improvment comprising:

• a flashlamp advancing member made of electrically conductive material and disposed to form an integral part of the firing circuit in a camera when said photoflash assembly is attached to the camera;
• said advancing member normally positioned at a predetermined location to contact an exposed lead segment of a unused flashlamp, for establishing an electrical connection between such lead segment and the firing circuit, and being movable in one direction against the lead segment to advance the flashlamp to the firing position and in another direction to re-position at the predetermined location for contact with an exposed lead segment of another flashlamp.

In a photoflash assembly of the type wherein a plurality of flashlamps are movable sequentially to a firing position and each of said flashlamps has a pair of exposed lead segments, and wherein said assembly is adapted for attachment to a camera having a flashlamp firing circuit with an electrical contact for contacting only one of the lead segments of a flashlamp in the firing position, the combination comprising:

• a flashlamp advancing member made of electrically conductive material and disposed to form an integral part of the firing circuit in a camera when said photoflash assembly is attached to the camera;
• said advancing member being positionable adjacent a flashlamp for contact only with the other lead segment of the flashlamp, for establishing an electrical connection between the other lead segment and the firing circuit, and being movable in contact with the other lead segment to advance the flashlamp to the firing position, whereby the flashlamp may be ignited by the firing circuit.

In a photographic camera of the type wherein (a) flashlamp advancing means is provided for moving a plurality of flashlamps sequentially to a firing position and (b) a firing circuit is provided for igniting a flashlamp in the firing position, the improvement comprising:

• said advancing means including an advancing member made of an electrically conductive material and forming an integral part of said firing circuit;
• and
• means for moving said advancing member to establish an electrical connection with the respective flashlamps, one at a time, and to advance a flashlamp electrically connected with the advancing member to the firing position.

In a photographic camera adapted for use with a multilamp flash assembly and of the type wherein (a) flashlamp advancing means is provided for moving a plurality of flashlamps in the assembly sequentially to a firing position and (b) a firing circuit is provided for igniting a flashlamp in the firing position, the improvement comprising:

• said advancing means including an electrically conductive advancing member forming an integral part of said firing circuit and disposed for electrical connection sequentially with the respective flashlamps when the multilamp assembly is used with said camera;
• and
• manually operated means for moving said advancing member to move a flashlamp electrically connected with the advancing member to the firing position.
