LIFE-BOAT.

SPECIFICATION forming part of Letters Patent No. 565,769, dated August 11, 1896.

Application filed July 25, 1895. Serial No. 557,146. (No modelo To @ZZ whom t may concern.-

Beit known that I, ROBERT D'. MAYO, of

Frankfort, in the county of Benzie and State of Michigan, have invented a new and useful Improvement in Life Boats or Floats, of which the following is a full, clear, and exact description. i My invention relates to animprovement in life boats or floats, and has for its object especially to improve upon the construction shown in the application fora patent for a similar device iiled of even date.

Another object of this invention is to provide a life boat or float in which the cage or carriage in which the persons are seated or contained will be unaffected by the movement of the hull, enabling the hull to turn upside down or stand upon either side without car rying the cage out of the perpendicular.

Another object of this invention is to provide a means for supplying air to the livingcompartment of the boat, the supply being unobstructed no matter in what position the boat may be placed, except when submerged, and whereby when the boat passes below the surface the water will automatically act to close the air-inlet temporarily, the valve through the medium of which the inlet is closed being automatically opened the mo-` in which similar characters of reference in-V dicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved boat." Fig. 2 is a vertical longitudinal section through the same. Fig. 3 is a transverse section on the line 3 3 of Fig. 2. Fig. 4 is a similar view on the line 4. i of Fig. 2. -Fig. 5 is a like section on the line 5 5 of Fig. 2. Fig. 6 is a detail sectional viewof a partition and ball-bearing supports located therein and adapted as partial supports for the car. Fig. 7 is a detail sectional view of a portion of an inner bulkhead and that portion of an airinlettube which `passes through the bulkhead; and Fig. 8 is a partial side elevation of the upper portion of the air-inlet tube, illustrating the manner in which the valve is controlled by the action of the water.

In carrying out the invention the hull A of the boat is preferably circular in cross-section and is tapering at its ends, being pro vided with a keel 10, which extends upward at its ends to meet a deck-rib 1l, while centrally between the deck-.rib and keel side ribs 12 are formed on the hull, which meet the combined end portions of the aforesaid deckrib and keel, as shown in Fig. 1. Under this construction no matter the boat rides upon its top, bottom, or side faces, it will be guided by a keel surface.

Near each end of the boat two bulkheads 13 and 14 are erected, a space intervening each pair of bulkheads for the purpose of admitting air, and this airreceiving chamber 15 is provided with apertures 1G, made in the hull and extending circumferentially thereof. The inner bulkhead 13 at each end forms at each extremity of the boat an air-tight compartment B, and between the inner bulkheads lei the living-compartmentl O of the boat is contained. W'ithin each of the air-receiving chambers 15 an upright airwsupply pipe 17 is placed, being contained wholly within said chamber, except that the lower end of each of the air-supply pipes or tubes is carried through an inner bulkhead 1i, as shown best in Figs. 2 and 7.

The bulkheads 11i are provided with suitable packing 18 around the elbow portion of the said air-supply pipes in order that water shall not enter the said living-compartment. Ball-bearings 19 are introduced between the elbow-section of each air-supply pipe and the bulkhead through which it passes, so that the hull of the boat may turn bottom up or upon its side without affecting the position of either of the said air-supply pipes. The balls are kept in place by lock-nuts 20, screwed upon the inner ends of the air-supply pipes, which are exteriorly threaded. y

A valve 21 is located at the top of each of IOO the air-supply pipes, and the valve is provided with standards 22, extending downward at each side of the pipe with which it is connected, and thel standards of each valve are connected through the medium of stems 24 with floats 23, the stems being pivoted to the said pipes at opposite sides, and the weight 0f these iloats will normally keep the valves open. The valves are guided by a central stem 25, (shown in Fig. 3,) and may be operated if anything should happen to the floats or when they are not brought in action by means of a chain 26 or its equivalent, attached to the stem of a valve and carried down through the air-inlet pipe and out at its inner or delivery end, as shown in Fig. 3. If in practice it is found desirable, but one float 23 may be used in operating the valve.

The living-compartment C is divided, preferably, by one or more skeleton partitions 27, (shown best in Fig. 4,) a single central one being illustrated in the drawings. The partition 27 contains an opening at its center in which ball-bearings 28 are placed for engagement with a stud 29, loosely passed through the aforesaid opening, the balls being` heldin place by a cap or nut 30, as shown in Fig. 6.

In each subcompartment of the living-compartment a car or cage D is located, comprising a frame 3l, corresponding in general contour to the bottom portion of the hull, and since the hull is preferably circular in crosssection the bottom of the frame is somewhat circular orsegmental. The frame is provided with end sections 32, and the end sections have arms 33 attached to their side portions,

the said arms being made to converge about centrally over the foot-sections and meet an upright 34. The upright at each end of the cage or car is made in sections connected by an adjusting-sleeve 35 or its equivalent, so that the bottom of the cage or car may be raised or lowered with respect to the bottom of the hull.

Each of the uprights 34 terminates at its upper end in an eye 36, and these eyes are interiorly threaded in order that the uprights at the outer ends of the car may be screwed upon the inner ends of the air-delivery tubes, while the eyes at the inner ends of the cars are screwed upon or otherwise secured to the stud or shaft 29, journaled in the partition 27 The framework of each car or cage is provided with any desired number of seats 37, conveniently arranged. Thus it will be observed that, no matter in what direction the hull may be turned, it will move without affecting the equilibrium of the cars or cages, which remain pendent, and if they have any motion at all have a slight pendulum one. In order that the cars shall have no end movement, guide-wheels 38 are placed at the ends of the car-frame for engagement, one set with the inner bulkheads and the other set with the partition 27. It is also evident that in the event the boat should become submerged for a short while and the y water should therefore enter the air-receiving chambers l5, as shown in Fig, 3, the water would raise the floats 23 and thereby automatically close the outer ends of the air-conducting tubes.

Suitable hatchways 39 are provided, whereby access may be had to the interior of the boat, and windows 40 are made in the inner bulkheads, receiving light from the air-receiving chambers l5, and a tube 4l is passed through each of the air-compartments B in order that a drogue line 42 may be attached to the vessel to keep its head to the sea.

This vessel is exceedingly simple and durable. It is economic in its construction, and will afford a comfortable and safe means of travel in the event of disaster at sea.

Having thus described my invention,I yclaim as new as far as completedl.
