BABNEY GOLDMAN, OF NEW YORK, N. Y.

UNSINKABLE LIFE-BOAT.

Specification of Letters Patent.

Patented June 3, 1919.

Application led April 19, 1918. Serial No. 229,528.

To all Iwhom t 'may fon/:ern: Y

Be it known that I, BARNEY GOLDMAN, a citizen of the United States, residing at New York city`y in the county oii New York and State of New York, have invented new and useful Improvements in Unsinkable Life- Boats, of which the following` is a. spcciication.

This invention relates essentially to a life boat in which a number oiz persons can sit on a practically nnsinkable tubular member made to surround the driving' mechanism for propelling the boat.

An object of the invention is to substautially form the tubular member in a longitudinal elliptic contour so as to oder a minimum resistance to the water and to shape it transverselyY with convex side portions to give it stability.

Another object of the invention is to provide the peculiar tubular shape member with a series of transverse partitions to divide the tube into a number of chambers each being an independent unit when punctured to prevent the others from filling.

The novel features of the invention are more fully described in the following` speciication and claims and illustrated in the accompanying drawing in which :M

Figure l represents a plan view of a boat embodying this invention.

Fig. 2 is a vertical transverse section of the same.

In this drawing the numeral 5 designates a tube which is preferably elliptic in longitudinal outline with corresponding ends so that the tube can be propelled either backward or forward. A number of transverse partitions 6 divide the tube into a series of compartments. Each end of the tube is provided with a fixture 7 for mounting;I a rudder 8 connected to the usual cords 9 operated by a person in the boat.

The transverse portions of the tube are shaped to include a Hat top 10 as indicated in Fig. 2 convex sides and semi-circular bottom with shallow contiguous walls to equipoise the tube in the water and prevent it from capsizing. The outer sides of the tube are provided with a number of rope rings 11 connected to eye xtures 12 to per mit a person swimming on the outside of the tube to grasp the rings. A railing consisting' of a series of tubular oste 13 each be ingi screwed into a socket 4: and connected together with ropes or cables will prevent anybody from fallinga olf the elliptic tube. A floor 15 is supported on the inner convexed sides of the tubular member.

The fiat top of the tubular member forms a seat extending the length ot' the tube for supporting a number of persons who can sit on the top with their feet resting on the floor.

The means for propelling the tubular member consists of. a paddle wheel 16 located centrally in the elliptic tubular member. The paddle wheel is rotatively mounted on a pair of standardsA 17 secured to the fioor. and a pinion 1S connected to a crank 19 can be operated by a person standingr on the Hoor to actuate the paddle wheel. There are two cranks shown so that two persons can operate at once or it permits the operator to always face the direction of travel without reversing the rotation of the crank.

It will be readily understood that when it is desired to store the boat the tubular posts can be unscrewed and the paddle dismounted by removing the standards, thus constitutingr a fiat package for stacking one tube on the other. The paddle. wheel can be. mounted in place after the tubular member is thrown into the water from a ship, simply by fasteningr the standards in place and adjusting the wheel gears. The tubular member can be stamped and shaped from thin metal and made practically airtight to give it suilicient buoyancy. The elliptic shape with almost sharp ends by oii'ering less resistance gives increased speed to the tubular member when driven through the water by a paddle wheel. The paddle wheel permits the boat to be used in shallow water or surf without danger of grounding or turning over. The fiat top can be provided with spaced arms to divide the top into a number of individual seats.

I claim 1. A life boat comprising an elliptic tubular member 'shaped to form a continuous hull, the said member having convexed sides and bottom with shallow contiguous walls to equi oise the member in the water, said mem er including a. fiat top to serve as a seat, and a deck supported on the inner convexed sides of the member.

2. A life boat comprising an elliptic tubular member sha ed to form a continuous hull, the said mem er having convexed sides and semicircular bottom with shallow conmy hand in the presence of two subscribing tiguous walls to eqdipbise ifle mnber in the Witnesses.

Water said member including u at top to y,

serve iis a seat, a deck supported on the inner BARNE GOLDMAN convexed sides of the member, and mtians for Witnesses:

propelling the boat.
