I d k Application filed March 26, 1903.1 $erial No. 149,716. (No model.)

To all whom, it WI/ALLZ/ con/cent:

Be it known that I, J AMES MOORE, acitizen of the United States, residing at Boston, in

the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Life- Saving Devices, of which the following is a specification.

Referring to the drawings, Figure 1 is an inverted perspective view of my improved life-saving device, thesame being shown with the pneumatic tubes folded over thereon, the.

several parts being in the relative positions occupied thereby when'the device is used as a mattress. Fig. 2 is a perspective view of the device with the several parts in the relative positions occupied thereby when the device is used as a life-saving-raft. Fig. 3 is a transverse section taken on line 3 3 of Fig.2.

Like numerals refer to like parts throughout the several views of the: drawings.

In the drawings, 5 is a mattressfilled with any suitable buoyant material, such as cork or shavings.

6 is a metal framework formed in two parts" 7 and 8 The mattress 5 is providedwith strips 9 9, extending therearound, preferably midway between the top and bottom of said mattress and forming the edges of the covering of said mattress, which coveringis made in two parts. The said strips are sewed together and then inserted between the two parts 7 and 8 of the frame 6, said frame being preferably made of aluminium, said two parts 7 and 8 beingriveted firmly together, and thus holding the mattress firmly secured thereto.

A compartment lO'is provided in the mattress 5, having covers 11 11 extending thereacross when the device is used as a mattress,

and in this compartment is stored a rudder matic tubes 17 are held in the position shown in Fig. 2 by braces 20 20, pivoted at 21 to the frame 6 and fastened to the arms 18 by pins 22 22.

In Fig. 1 I have illustrated my improved life-saving device in an inverted position as the same appears when folded up and adapted for use as a mattress, in which the pneumatic tubes are folded over upon the under side of the mattress, the rudder 12 and tiller 13 being placed in the compartment and the covers 11 closed down thereover. -The jointed mast is folded down and the sail 23 placed thereunder, while a pneumatic tube rests upon the sail and holds itfirmly against the mattress. When the device is arranged to be used as a life-saving raft, the pneumatic tubes are folded over outwardly from the mattress and into the position shown in Fig. 2, and the pivoted braces 20 are joined to the arms 18 by means of the pins 22. The mast is tilted upwardly into a vertical position and the sail 23 attached thereto. rudder 12 and tiller 13 are taken from the compartment 10 and attached to the framework 6, as shown in Fig. 2.

The device forms as a whole a compact and useful article when in use as a mattress and may readily be changed to be used as a life-saving raft in the manner indicated. It will be understood that when the device is in use as a life-saving raft the user'sits in the compartment 10 and manages the device from that position.

While I have described my improved lifesaving mattress as having pneumatic tubes hinged thereto, it is evident that said tubes may be filled with cork or any material which The , tress, a pair of buoyant tubes hinged to said framework upon opposite sides thereof, and braces extending from said framework to said tubes.

In a life-saving device, a mattress, a framework fast to and surrounding said inattress, arms hinged to opposite sides of said framework, a pair of buoyant tubes fast to said arms, and braces pivoted at one end to said framework and adapted to be fastened at the other end thereof to said arms.

,4. In a life-saving device, a mattress, a

framework fast to and surrounding said mattress, a pair of buoyant tubes hinged to said framework upon opposite sides thereof, and a jointed mast hinged to said framework.

5. In a life-saving device, a mattress, a framework fast to and surrounding said mattress, and a pair of buoyant tubes hinged to said framework upon opposite sides thereof, said mattress provided with a compartment for the purpose specified.

6. In a life-saving device, a mattress provided with longitudinal strips on the sides thereof, a framework in two parts clamped to said strips and surrounding said mattress, and a pair of buoyant tubes hinged to said framework upon opposite sides thereof.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JAMES MOORE.
