THE EMPIRE LIFE-SAVING NET.
THIS invention relates to improvements in life-saving apparatus for use at fires, and its object is to provide a net strong enough to resist the weight of bodies falling from a great height, and which shall be provided with suitable means about its circumference for keeping the tension equal. These objects are attained by the mechanism illustrated in the accompanying drawings.
Heretofore appliances used at fires for a similar purpose have consisted either of textile fabric with handles attached around the edge, or else of cotton webbing, in which the warp and woof were each in parallel lines and sewed together at the points of crossing. These forms of apparatus were not sufficiently strong to resist the weight of falling bodies and were liable to sag. By means of this invention these difficulties are entirely removed.
In the drawing A represents a central ring, preferably of steel, about eight inches in diameter, and bronzed to prevent it from rusting. From this ring project radially the cords B to the outer ring C, which is composed of a stout rope, preferably of Russian, and about one inch in thickness. Between the central ring A and the outer ring C are arranged in concentric circles rings D, composed of strong rope. The radial ropes B are knotted, spliced or seized to the central ring A, and to each of the concentric rings D, and also to the outer ring C, and these radial ropes B extend entirely across the apparatus, crossing one another within the central ring A. All the parts of this apparatus should be of the strongest material, and the points of knotting, splicing or seizing should be made perfectly secure.

In practice the outer ring C forms a continuous handle, which may be grasped by a large number of men, and, as the radial lines B extend from the ring C directly towards the centre, the outward pull upon the ring C will cause the entire apparatus to be perfectly taut, and the strain of any body falling upon it to be borne equally by all the parts. At the same time, the construction of the apparatus is such that it may be rolled up and packed into a very small space. The net is ten feet in diameter and weighs thirty-five pounds.
These nets have been adopted by the fire departments of New York, Brooklyn, Baltimore, Bayonne, N. J., and Cleveland, O., and their value has been in practice repeatedly demonstrated. Their lightness and compactness adapt them for the equipment of any hook and ladder truck, hose wagon or carriage or patrol wagon.
