WATER-HAMMOCK.

Application filed September 3.7, 1917.

To all whom it may concern.

Be it known that l, Enema Unnnnwoon, a citizen of the United States, residing at Gary, in the county of Lake and State of Indiana, have invented a certain new and useful Improvement in \Vaterl lammocks, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to water hammocks and has for its object the provision of a hammock structure adapted more particularly for use in the water for pleasure purposes. In general, my invention comprises a cradle or stretcher portion, the opposite ends of which are buoyed up by suitable means so that the user may lie on the stretcher portion on top of the water.

In one form of my invention I utilize pneumatic pillows as the buoying means, and my invention contemplates the provision of improved valve mechanism for these pneumatic pillows.

I will describe my invention more in dc tail by referring to the accompanying drawing illustrating one form which my invention may take, in which Figure l is a perspective view of my im' proved water hammock, the position of the user being indicated in dotted lines;

Fig. 2 is a sectional view on line 22 of Fig. 1;

F i. 3 is a sectional view on' line 3-3 of Fig. a, and

Fig.4: is a sectional view along line H of Fig. 2.

My improved water hammock comprises the cradle or stretcher portion 5 which is held taut between two buoyant supports 6 and 7 which are fastened to the opposite eX- tremities of the cradle portion The cradle portion is fastened throughout the greater portion of its width to the buoyant supports, but a portion thereof is unfastened or preferably cut away as shown at 7. This accommodates the rounding of the buoyant supports 6 and 7 when they are blown up without distorting the cradle portion. Straps 8 however maintain the proper alinement of the cradle and its supports. These straps 8 may be made of rigid material, if so desired, bent to the shape shown in Fig. 1, but they are preferably made of several plies of canvas stitched together and to the Specification of Letters Patent.

sides of the cradle and to the ends of the pillows. l Vhen thus made they are strong enough to cause the cradle and pillows to remain. in alinement. The buoyant supports as shown herein are bags which are adapted to be blown up, thus forming pneumatic chambers. Each of the bags is provided with a valve structure as shown more clearly at 9. This valve structure is shown in detail more particularly in Figs. 2, 3 and 4:.

The bag 6, for instance, has an outer flap l0 sewed to it throughout the entire length of this outer flap. A hole 11 is provided through the pneumatic bag 6 under the flap. A month piece 1:2 is fastened to the flap 10 so that air may beblown into the interior of the bag 6. The pneumatic bags 6 and 7 are made of material which will hold the air a sufficient length of time for the purpose desired. Assuming that it is desired to blow up the bag, then the finger pieces 13 and 14 are grasped to straighten out that portion of the bag through which the hole 11 passes, away from the flap 10, whereupon air may be blown in through the mouthpiece 12 until the bag is inflated. The presence of the air then presses the bag portion tightly against the flap 10 to prevent the air from escaping through the hole 11.

From what has been thus described the nature of my invention will be readily clear to those skilled in the art.

Having thus described means for carrying out my invention, what I claim as new and desire to secure by Letters Patent is:

1. A water hammock comprising a pair of buoyant pillows, a pair of light strips connecting the pillows along their side edges, and a yieldable cradle portion supported by the strips to be drawn taut by the expansion of the pillows.

2. A water hammock con'iprising a pair of buoyant pneumatic pillows, a light frame work and cradle connecting the pillows, said frame work and cradle being drawn taut by the expansion of the pillows.

3. A Water hammock comprising a pair of buoyant pneumatic pillows, a light yieldable frame adapted to be turned up at an angle at the ends and supporting the pillows at an incline at each end, and a yieldable cradle portion supported by the frame and pillows.

i. A water hammock comprising a pair of rectangular buoyant pneumatic pillows, a light foldable connecting frame secured to and a yieldthe side ed es of the pillows,

the

able cradle portion supported between connecting frame.

5. A water hammock comprising a pair of buoyant pillows, a Valve structure for each of said pillows, a pair of strips connecting the pillows along their edges and a yieldable cradle portion supported by said strips, the parts being so constructed that the expansion of said pillows will close the valve structures and draw taut the cradle.

6. A water hammock comprising a pair of buoyant pneumatic pillows, a valve structure for each of said pillows, and a framework and cradle connecting the pillows, said framework and cradle being drawn taut and said Valve being held closed by the expansion' of said pillows.

In witness whereof, I hereunto subscribe my name this fourteenth day of August, A. D. 1917.
