Abstract
Abstract A flash tube holder assembly includes a reflector for mounting two sets of spaced terminal blocks; one set mounts resilient contact strips to electrically engage and physically hold the terminal ends of a flash tube, while the other set mounts the ends of a trigger wire in longitudinally extending, contiguous relation to the tube. Each tube terminal block is formed of two sections interconnected by its resilient contact strip, which sections are manually separable to open the contact strips for tube removal.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
172 words
A flash tube holder assembly for mounting an elongated flash tube having a contact ferrule at each end, said assembly comprising, in combination: A. a longitudinally elongated reflector; B. a pair of longitudinally spaced, first terminal blocks, each formed in first and second sections, 1. said first section of each said first terminal block secured to said reflector; C. a resilient contact strip mounted by each said first terminal block, each said strip having 1. its ends anchored to said first and second sections of each said first terminal blocks, and 2. a central portion arranged transversly of the flash tube and conformed to embrace the contact ferrule at one end of the flash tube; and D. a handle secured to each said second terminal block section to facilitate forcible separation of said first and second terminal block sections along a direction transverse to the flash tube, 1. whereby to deform said central portions of said contact strips and thereby relax the physicAl hold on the contact ferrules of the flash tube.
Claim 2
Dependent Claim
172 words
A flash tube holder assembly for mounting an elongated flash tube having a contact ferrule at each end, said assembly comprising, in combination: A. a longitudinally elongated reflector; B. a pair of longitudinally spaced, first terminal blocks, each formed in first and second sections, 1. said first section of each said first terminal block secured to said reflector; C. a resilient contact strip mounted by each said first terminal block, each said strip having 1. its ends anchored to said first and second sections of each said first terminal blocks, and 2. a central portion arranged transversly of the flash tube and conformed to embrace the contact ferrule at one end of the flash tube; and D. a handle secured to each said second terminal block section to facilitate forcible separation of said first and second terminal block sections along a direction transverse to the flash tube, 1. whereby to deform said central portions of said contact strips and thereby relax the physicAl hold on the contact ferrules of the flash tube.
Claim 3
Dependent Claim
55 words
a central portion arranged transversly of the flash tube and conformed to embrace the contact ferrule at one end of the flash tube; and D. a handle secured to each said second terminal block section to facilitate forcible separation of said first and second terminal block sections along a direction transverse to the flash tube,
Claim 4
Dependent Claim
55 words
a central portion arranged transversly of the flash tube and conformed to embrace the contact ferrule at one end of the flash tube; and D. a handle secured to each said second terminal block section to facilitate forcible separation of said first and second terminal block sections along a direction transverse to the flash tube,
Claim 5
Dependent Claim
48 words
The assembly defined in claim 1, which further includes A. a pair of spaced, second terminal blocks fixedly connected to said reflector; and B. an elongated triggering electrode extending in contiguous, longitudinal relation to the tube, said triggering electrode mounted at its ends by said second terminal blocks.
Claim 6
Dependent Claim
24 words
The assembly defined in claim 2, wherein said second terminal blocks are respectively integrally formed with said first sections of said first terminal blocks.
Claim 7
Dependent Claim
67 words
The assembly defined in claim 2, wherein one of said first and second sections of each said first terminal block is formed with a passage therethrough, and the one end of each said contact strip anchored to each said one section is inserted through said passage, said one contact strip ends provided with means to engage said one terminal block section at opposed ends of said passages.
Claim 8
Dependent Claim
68 words
The assembly defined in claim 2, wherein said central portion of each said contact strip is in the form of a clip, slightly greater than semicircular in cross-section and slightly less in diameter than the contact ferrules of the flash tube, whereby to tightly embrace the contact ferrule and wherein forcible separation of said first and second terminal block sections opens said clips to release the flash tube.
Claim 9
Dependent Claim
113 words
A flash tube holder assembly for mounting an elongated flash tube, said assembly comprising, in combination: A. a longitudinally elongated reflector; B. a pair of longitudinally spaced, first terminal blocks carried by said reflector; C. a pair of longitudinally spaced, second terminal blocks carried by said reflector; D. a triggering wire mounted at its ends by said second terminal blocks and having an elongated, longitudinally extending central portion; and E. separate contact means mounted by said first terminal blocks for electrically engaging and physically holding the contact terminal ends of the flash tube, whereby the flash tube is mounted independently of said triggering wire in contiguous, longitudinal relation with said central portion thereof.
Claim 10
Dependent Claim
113 words
A flash tube holder assembly for mounting an elongated flash tube, said assembly comprising, in combination: A. a longitudinally elongated reflector; B. a pair of longitudinally spaced, first terminal blocks carried by said reflector; C. a pair of longitudinally spaced, second terminal blocks carried by said reflector; D. a triggering wire mounted at its ends by said second terminal blocks and having an elongated, longitudinally extending central portion; and E. separate contact means mounted by said first terminal blocks for electrically engaging and physically holding the contact terminal ends of the flash tube, whereby the flash tube is mounted independently of said triggering wire in contiguous, longitudinal relation with said central portion thereof.
Claim 11
Dependent Claim
27 words
The assembly of claim 6, wherein each said end of said triggering wire is mounted by a separate contact strip anchored to each said second terminal block.
Claim 12
Dependent Claim
98 words
The assembly of claim 7, wherein each said first terminal block consists of first and second sections, each said first section secured to said reflector, each said contact means in the form of a resilient contact strip anchored at its ends to said first and second sections and having a central portion conformed to electrically engage and physically hold a terminal end of the flash tube, each said second section including a handle for inducing forced separation of said sections and coincident distortion of said contact strip central portions to release the terminal ends of the flash tube.
Claim 13
Dependent Claim
40 words
The assembly defined in claim 8, wherein one end of each said triggering wire mounting contact strips and each said tube holder resilient contact strips is extended beyond their respective mounting terminal blocks to facilitate electrical connection to external circuitry.
Claim 14
Dependent Claim
57 words
The assembly defined in claim 8, wherein said central portion of each said resilient contact strip is in the form of a clip slightly in excess of semicircular in cross-section and slightly less in diameter than the terminal ends of the flash tube, whereby each said central portion tightly embraces one of the flash tube terminal ends.
Claim 15
Dependent Claim
60 words
The assembly defined in claim 8, wherein one of said first and second sections of each said first terminal block is formed with a tongue slidingly accommodated in a groove formed in the other of said first and second sections of each said first terminal block, whereby to guide said second sections in their movement relative to said first sections.
