JOHN GUNNARSON, OF BETTENDORF, IOWA.

LIFE-BOAT.

Specification of Letters Patent. Patented J 11y 21, 1914,

Application filed March 6,1914. Serial No. 822,861.

To all whom it may concern Be it known that 1, JOHN GUNNARsoN, a citizen of Sweden, residing-at Bettendorf, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Life-Boats, of which the following is a specification.

This invention relates to improvements in life boats and its object is to produce a device of this class provided with a cover for the hull of the boat and said cover is spaced away from the hull by a plurality of springs in such a manner as to form a shock absorber by means of which an impact received at any point upon the hull of the boat is evenly distributed over the same and the danger from such possible impacts resulting from collisions, buifeting of the waves, etc, reduced to the minimum. Novel air supply means extending through the cover and hull are also provided by means of which a fresh supply of air is constantly admitted to the boat without the admission of water.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claims and illustrated in the accompanying drawings which form a part of said specification and in which.-

Figure 1 is a side elevation of my improved life boat with a portion of the cover removed. Fig. 2 is a plan of the same. Fig. 3 is a cross section taken on line 33 of Fig. 1. Fig. 4 is a sect-ion through a portion of the cover and hull showing the spring connection therebetween. Fig. 5 is a similar view taken at another point of the boat. Fig. 6 is an end view of Fig. 5. Fig. 7 is a section through the hull and cover of the boat showing the form of air inlet means employed. Fig. 8 is a section through a portion of the cover showing rope girdle extending about the same and supporting means for said girdle. Fig. 9 is a front view of the same.

Like reference characters indicate corresponding parts throughout the several views. The reference numeral 1 indicates the hull of a boat which is provided along its lateral exterior surface with a plurality of springs 2 which carry a cover 3 formed of canvas, rubber or other suitable material and said cover is secured toeach gunwale of the boat and passed beneath the keel of the same. At suitable intervals insaid cover guides 4 are secured which carry a rope girdle or life line 5 which extends completely about the boat and affords means for persons in the water to attach themselves to the boat. To the cover 3 a flap is secured and adjacent the same straps 7, 8 are secured, respectively, to the cover and to a storm cover 9 which, when in use, extends entirely across the top of the boat, and into said keepers, to protect the occupants thereof from the inclemency of the weather or the dangers of the sea. The straps 7, 8 are buckled together as at 10 to closely unite the cover 3 and the storm cover 9.

11 is an angular air inlet, the body of which extends into the hull of the boat and the T-shaped head 12 of which extends through the cover 3 to admit air tothe boat. Any water enteringthe head 12 willpass out through and connecting said cover and hull.

2. In a life boat the combination with the hull, of a plurality of springs, a cover connected'to the gunwales of the boat and to said springs, angular air inlets passing through and connecting said cover and hull and a storm cover releasably secured to the first named cover and passing over the top of the boat.

In testimony that I claim the foregoing as o my own I have hereto afiixed my signature in the presence of two subscribing witnesses.

JOHN GUNNARSON.
