Abstract
Abstract Signal apparatus for use in geodetic surveys, land surveys, emergency use, and so forth. The signal apparatus comprises a panel signal wherein panels incorporated therein are constructed to facilitate wind-spillage in a manner such as to preclude the panel signal structure from tipping or blowing over upon the presence of excessive wind pressures. The panel structure is lightweight, a self-contained unit, and includes, preferably, flexible arm mounts constructed to mount signal panels in such a manner that these panels can ''''spill'''' or pass oncoming gusts of wind without chancing the blowing over of the structure.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
59 words
An observation signal device including, in combination, an upstanding elongate member, means for anchoring said upstanding elongate member to the ground in an upright position, plural pairs of outwardly extending, vertically spaced arms universally resiliently mounted to and extending outwardly from said upstanding elongate member, and plural observation panels respectively connected to and between respective pairs of said arms.
Claim 2
Dependent Claim
59 words
An observation signal device including, in combination, an upstanding elongate member, means for anchoring said upstanding elongate member to the ground in an upright position, plural pairs of outwardly extending, vertically spaced arms universally resiliently mounted to and extending outwardly from said upstanding elongate member, and plural observation panels respectively connected to and between respective pairs of said arms.
Claim 3
Dependent Claim
51 words
Structure according to claim 1 wherein said device includes plural universally resilient yieldable means mounted to respective ones of said arms and secured to said upstanding elongate member for enabling the ommidirectional flexure of said arms relative to said upstanding member, whereby to permit wind loads to spill off said panels.
Claim 4
Dependent Claim
22 words
Structure according to claim 2 wherein said plural yieldable means individually comprise spring mounts coiled about the axis of its respective arm.
Claim 5
Dependent Claim
104 words
An observation signal device including, in combination, an upstanding elongate member, means for anchoring said upstanding elongate member to the ground in an upright position, plural pairs of outwardly extending, vertically spaced arms mounted to and extending outwardly from said upstanding elongate member, and plural observation panels respectively connecteD to and between respective pairs of said arms, and wherein said upstanding member comprises a hollow tube, a container fitted in one end of said hollow tube, and means for closing the remaining end of said hollow tube, said container and said hollow tube beneath said container including interior storage chambers for signal device accessories.
Claim 6
Dependent Claim
104 words
An observation signal device including, in combination, an upstanding elongate member, means for anchoring said upstanding elongate member to the ground in an upright position, plural pairs of outwardly extending, vertically spaced arms mounted to and extending outwardly from said upstanding elongate member, and plural observation panels respectively connecteD to and between respective pairs of said arms, and wherein said upstanding member comprises a hollow tube, a container fitted in one end of said hollow tube, and means for closing the remaining end of said hollow tube, said container and said hollow tube beneath said container including interior storage chambers for signal device accessories.
Claim 7
Dependent Claim
98 words
An observation signal device including, in combination, an upstanding elongate member, means for anchoring said upstanding elongate member to the ground in an upright position, plural pairs of outwardly extending, vertically spaced arms mounted to and extending outwardly from said upstanding elongate member, and plural observation panels respectively connected to and between respective pairs of said arms, and wherein said upstanding elongate member includes an elongate hollow interior, plural fitted-together tubular members secured to and depending from said upstanding elongate member and constructed for mutual separation and telescoping storage within said hollow interior of said upstanding elongate member.
Claim 8
Dependent Claim
98 words
An observation signal device including, in combination, an upstanding elongate member, means for anchoring said upstanding elongate member to the ground in an upright position, plural pairs of outwardly extending, vertically spaced arms mounted to and extending outwardly from said upstanding elongate member, and plural observation panels respectively connected to and between respective pairs of said arms, and wherein said upstanding elongate member includes an elongate hollow interior, plural fitted-together tubular members secured to and depending from said upstanding elongate member and constructed for mutual separation and telescoping storage within said hollow interior of said upstanding elongate member.
Claim 9
Dependent Claim
24 words
Structure according to claim 5 wherein said upstanding elongate member includes a depending tail cone releasably receiving an uppermost one of said tubular members.
Claim 10
Dependent Claim
34 words
Structure according to claim 5 wherein the lowermost one of said tubular members has a lower extremity closed by a centering pointer, said tubular member being constructed in the aggregate to contain weighting material.
Claim 11
Dependent Claim
60 words
Structure according to claim 5 wherein each of said tubular members includes an upper, flared, inter-tubular member fitting portion, said device including a ring exterior engaging a respective flared cutting portion, flexible elongate connectors secured to said ring and constructed for securement to said anchoring means, said anchoring means, in part, comprising ground-tie cords connected to said flexible elongate connectors.
Claim 12
Dependent Claim
75 words
Signal structure having a depending tube, a reversible pointer member having a medial peripheral abutment flange, a centering apex on one end, and a solely centered centering depression at the remaining end, said pointer member being positioned in said depending tube such that said peripheral flange abuts the same. 10 A reversible pointer member having a medial peripheral flange, a centering apex at one end, and a solely centered centering depression at the remaining end.
Claim 13
Dependent Claim
75 words
Signal structure having a depending tube, a reversible pointer member having a medial peripheral abutment flange, a centering apex on one end, and a solely centered centering depression at the remaining end, said pointer member being positioned in said depending tube such that said peripheral flange abuts the same. 10 A reversible pointer member having a medial peripheral flange, a centering apex at one end, and a solely centered centering depression at the remaining end.
