Life Saving Hook Spring.

Life Saving Hook Spring.

A recent accident occurred in Boston, whereby a fireman, while practicing with a life-saving spring, fell a distance of thirty feet and received injuries which render him a cripple. The hook at present in use is made with the spring or snap in the side near the top, and the rope is liable to work up and out of the snap opening, thus let_____ing the man on the line fall. To do away with any risk in using a life-saving spring, Charles E. Berry of Cambridge, Mass., has invented one which promises to become very popular on account of its safety. This spring is in the shape of a hame, with the snap at the bottom instead of at the side, and it is made on the same principle as the Berry hame. The rope, when wound around the spring, works over the snap which guarantees its safety, as the snap can only be opened from pressure outside. The spring can be made of all sizes to suit the requirements of fire departments, and it especially commends itself, as it can be easily attached to a ladder or bar without delay or risk of loosening the rope. The invention is shown in the illustrations.
