Abstract
Abstract A signal device which utilizes a plurality, e.g., ten, of percussively-ignitable flashlamps and is designed for single-handed operation. The device also comprises a body member which includes a handle portion and a support portion for having the lamps mounted thereon. A trigger moves in response to manual actuation between the handle and support portions in a reciprocal manner to in turn actuate the device's firing mechanism located within the support portion of the body. The firing mechanism, e.g. ratchet and helical torsion spring, in turn selectively fires each of the lamps in response to this reciprocal movement.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
98 words
A hand-operable signal device comprising: an elongated body member including a support portion and a handle portion; a plurality of percussively-ignitable flashlamps mounted on said support portion; a trigger member movably oriented on said elongated body member substantially between said support and handle portions and adapted for reciprocal movement therebetween; and a firing mechanism located within said support portion relative to each of said percussively-ignitable flashlamps, said firing mechanism operatively joined to said trigger member for selectively firing each of said flashlamps in response to said reciprocal movement of said trigger member between said support and handle portions.
Claim 2
Dependent Claim
98 words
A hand-operable signal device comprising: an elongated body member including a support portion and a handle portion; a plurality of percussively-ignitable flashlamps mounted on said support portion; a trigger member movably oriented on said elongated body member substantially between said support and handle portions and adapted for reciprocal movement therebetween; and a firing mechanism located within said support portion relative to each of said percussively-ignitable flashlamps, said firing mechanism operatively joined to said trigger member for selectively firing each of said flashlamps in response to said reciprocal movement of said trigger member between said support and handle portions.
Claim 3
Dependent Claim
24 words
The signal device according to claim 1 wherein said percussively-ignitable flashlamps are mounted in two separate rows on opposing sides of said support member.
Claim 4
Dependent Claim
19 words
The signal device according to claim 2 wherein the number of flashlamps within each of said rows is five.
Claim 5
Dependent Claim
21 words
The signal device according to claim 2 wherein said rows of flashlamps on opposing sides of said support member are parallel.
Claim 6
Dependent Claim
25 words
The signal device according to claim 1 further including light-transmitting cover means positioned on said support portion of said body member for covering said flashlamps.
Claim 7
Dependent Claim
35 words
The signal device according to claim 1 further including a plurality of light shielding members, each of said members positioned on said support portion of said body member between a respective pair of said flashlamps.
Claim 8
Dependent Claim
42 words
The signal device according to claim 1 wherein each of said percussively-ignitable flashlamps includes a light-transmitting envelope and a primer tube projecting therefrom and said support member contains a plurality of spaced openings therein each for accommodating one of said primer tubes.
Claim 9
Dependent Claim
56 words
The signal device according to claim 7 wherein said firing mechanism comprises an elongated ratchet member operatively joined to said trigger member and a resilient striking mechanism in engageable contact with said ratchet member for selectively striking each of said projecting primer members of said flashlamps in response to said reciprocal movement by said trigger member.
Claim 10
Dependent Claim
16 words
The signal device according to claim 1 wherein said elongated body member is of two-piece construction.
