Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
172 words
The combination with an elongate mailbox having a pivoted door at the forward end thereof and a vertical wall at the rear end thereof, of a signal comprising a rod-like bracket secured to the rear wall, said bracket extending upwardly, rearwardly and transversely therefrom, the transversely extending upper portion defining a horizontally directed pivot disposed at an elevation above a spatially adjacent portion of the mailbox and rearwardly beyond said rear wall, a rectilinear tubular flagstaff pivotally mounted on said pivot, said flagstaff having an unfilled portion extending forward from said pivot over the entire length of said mailbox and a shorter weight-containing portion projecting rearwardly from said pivot, weight means disposed within said weight-containing portion, said weight means having a density substantially greater than that of the material Forming said flagstaff and present in an amount sufficient to continuously urge said flagstaff to swingable movement about said pivot from a horizontal position to a vertical position, and latch means movable with said door for restraining the swingable movement of said flagstaff.
Claim 2
Dependent Claim
172 words
The combination with an elongate mailbox having a pivoted door at the forward end thereof and a vertical wall at the rear end thereof, of a signal comprising a rod-like bracket secured to the rear wall, said bracket extending upwardly, rearwardly and transversely therefrom, the transversely extending upper portion defining a horizontally directed pivot disposed at an elevation above a spatially adjacent portion of the mailbox and rearwardly beyond said rear wall, a rectilinear tubular flagstaff pivotally mounted on said pivot, said flagstaff having an unfilled portion extending forward from said pivot over the entire length of said mailbox and a shorter weight-containing portion projecting rearwardly from said pivot, weight means disposed within said weight-containing portion, said weight means having a density substantially greater than that of the material Forming said flagstaff and present in an amount sufficient to continuously urge said flagstaff to swingable movement about said pivot from a horizontal position to a vertical position, and latch means movable with said door for restraining the swingable movement of said flagstaff.
Claim 3
Dependent Claim
26 words
The subject matter of claim 1, wherein the pivot upon which said tubular flagstaff is mounted extends horizontally through the longitudinal axis of said tubular flagstaff.
Claim 4
Dependent Claim
38 words
The subject matter of claim 1, wherein closure means at the rearward end of the weight-containing portion of the flagstaff cooperates with the pivot upon which the flagstaff is mounted to fix the position of the weight means.
