LIFE BOAT.
APPLIUATION FILED NOV.14, 1906.
CARL LEHNERIT, OF MARXLOH, GERMANY.
LIFE-BOAT.
Specification of Letters Patent.
Patented Feb. 19, 1907.
Application filed November 14, 1906. Serial No. 343,454.
To all whom it may concern.-
projecting inner screw-threads, into which Be it known that I, CARL LEHNERT, a subanother long pipe can be screwed from inside,
ject of the German Emperor, and resident of Marxloh, Ruhrort District, Germany, have invented certain new and useful Improvements in Life-Boats, of which the following is a specification.
This invention relates to a new or improved life-boat which is made of aluminium. mixed with any appropriate metal alloy.
The accompanying drawings show the boat embodying the invention.
Figure 1 is an elevation, Fig. 2 a longitudinal vertical section, and Fig. 3 a transverse vertical section, of the same.
The life-boat essentially comprises the lower part a and the upper part b, which are hingedly connected to one another at their rear ends. Between the two boat parts a tightening of india-rubber or any other suitable material is placed. The two parts are rigidly and tightly held together by means of fly-screws 0, arranged inside the boat and passed through the projecting edges of the two parts. In order to allow an inspection toward the sea, the up per part b is at its front end provided with a glass d of great resisting capacity.
To move the boat forward, two paddlewheels e and f are arranged in the upper boat part outside the boat in such a manner as to reach into the water and to be capable of being actuated from inside the boat by means of a toothed or chain gearing and a handle or through the medium of any convenient power source, preferably an electromo'tor. In order to prevent water from entering the boat through the bearings of the paddle-wheels, the axles of the latter are passed through stuffing-boxes. A rudder g is arranged at the rear end of the boat and also adapted to be manipulated from inside the boat, its supportingaxle being for this purpose also passed through a stufling-box.
The air is admitted through a pipe h, which can be closed toward the outside by a flap or a slide. In order to allow of this pipe being made longer, which is especially necessary at rough sea, the same is provided with so as to project in suflicient height over the top of the boat.
A separate safety-flap & is provided in the top of the upper part b.
The boat can be carried with the steamers and the like in similar manner as the hitherto used life-boats.
By means of flags carried with the boat and which are to be passed on a rod through the air-inlet pipe the occupiers of the boat can make themselves conspicuous to passing ships and the like.
Having fully described my invention, what I claim, and desire to secure by Letters Pate ent, is
Life-boat, comprising in combination, a lower part a made of aluminium mixed with any suitable metal alloy, an upper part b hinged to said lower part and made of the same material as said lower part, a tightening placed between said two parts, fly-screws 0 passed through the projecting inner edges of said two parts and adapted to hold the latter tightly and rigidly together, a glass (1 provided at the front end of the boat and adapted to allow an inspection toward the sea from inside the boat, paddle-wheels e,f arranged outside the boat so as to reach into the water and passed with their axles through stuflingboxes in said upper part of the boat so as to be capable of being actuated from inside the boat, a rudder 9 provided at the rear end of the boat and also passed with its supportingaxle through a stufling-box in the rear end of the boat so as to be capable of being operated from inside the boat, an air-inlet pipe h provided at the top of the boat and adapted to be closed and to be made longer if required, and a safety-fiap i provided in the top of the boat, substantially as described and shown.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
CARL LEHNERT. Witnesses: I
