D. Gutter-mounted Cylinder. When a gutter and fire blanket cylinder are combined, this is how it would work, with the weight rod pulling the blanket down with gravity after the electromagnetic blanket cylinder release mechanism (see figure V) lets the bar drop.
E. Profile of Gutter-mounted Cylinder. Note that the gutter-cylinder combination makes a smooth, aesthetic hybrid, mounted—like most gutters—on the eaves end board.

Fire Blanket Plans
Fire Blankets From A to Z
A. Single Ridge Cylinder. This cylinder holds a fire blanket (of fireproof material for preventing exterior fires from harming the house) that can potentially cover a house all the way from the ground on one side, up the wall, up one roof slope and down the other slope, and down the far wall to the ground. Note the blanket—all one piece—has its leading edges coming out two different slots. One end of the cylinder will have a motor for rewinding; it'll rewind both blanket areas at once. Both blanket edges will have weight rods attached to their leading edges and a cable attached to each bar that extends down the side of the house to a motor (see figure L).
B. Double Ridge Cylinders. These cylinders are like figure A, above, except there are two, which allows the cylinders to be smaller and mounted in a more stable configuration. Two cylinders doesn't necessarily mean two motors, since one motor could drive both via gears.
C. Before. This is the before picture—a profile of normal eaves, gutter, and rafter facing board.
F. Two-way Gutter-mounted Cylinder. Note the different profile of the gutter-cylinder combination. This would make it easier for the blanket to smoothly go up the roof to the ridge-mounted eye bolt. A motor is mounted beneath the ridge eaves to reel in the cable—via a pulley—and drag the blanket (with a weight rod on its leading edge) to protect the roof. The wall blanket will also unroll downward when the motor operates. It will be aided by gravity operating on its weight rod. Highlighted details in this figure include the grommet in the blanket used as a place to hook onto the weight rod via an eye bolt, and an eye-bolt-mounted spring-locked hook on the weight rod for the homeowner to hand-fasten to a molly-bolt anchor in the ground. (bl. = fire blanket, ca. = cable, Mo. = motor, w.r. = weight rod, and s.h. = spring-locked hook)
