I LIFE-RAFT.

SPECIFICATION forming part of Letters Patent No. 678,297, dated July 9, 1901. Application filed March 28,1901. Serial No. 53,195. (no model.)

To allwhom it may concern.-

Be it known that L'JOHN VALENTINE J ANIN, a citizen of the United States,'and a resident of Seattle, in the county of King and State of Washington, have invented a new and Improved Life-Raft, of which the following is a full, clear, and exact description.

This invention relates to improvements in pneumatic life-rafts; and the object is to provide a life-raft 'of simple construction that shall be light, yet strong and serviceable, and having means attached to it whereby it may be quickly inflated, either when floating or on shipboard.

I will describe a life-raft embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of a pneumatic liferaft embodying my invention. Fig. 2 is a transverse section on the line a: m of Fig. 1. Fig. 3 is an end View, on an enlarged scale, of one of the deck portions and the central pocket indicated in longitudinal section on the'line y y of Fig. 1. Fig. 4 is a transverse section of the central pocket. Fig. 5 is a similar section showing one of'the side pockets. Fig. 6 is a section of the pump casing and a pump therein in its raised position. Fig. 7 is a transverse section of the casing on the line 2 z of Fig. 6. Fig- 8 is a vertical section on the line to w of Fig. 6, showing the pivotal connection of the pump-body. Fig. 9 is an end elevation of a broken portion of one end ofthe pump-casing. Figs. 10 and 11 are plan views of perforated disks or valveseats employed in the pump-barrel. Figs. 12 and 13 are side and end elevations, respectively, of rope-holding brackets employed. Fig. 14. is a plan view showing a'slight modification. Fig. 15 is a section on the line y y of Fig. 14. .Fig. 16 is a section on the line a z of Fig. 14. Fig. 17 is a section on the line w w of Fig. 15. Fig. 18 is a section showing a modified form'of pump, and Fig. 19 is a section at right angles to Fig. 18.

The body portion of the life-raft comprises a casing 1, adapted to be inflated and consistin g, preferably, of canvas or like material made impervious to air and water. For the purpose of giving proper strength to the body portion 1 have divided it' into compartments 5 5 by cross partitions 2 and 3, openings being provided at the ends, as indicated at 4., so that the inflating air 'or gas may circulate from one compartment to another. These partitions may consist of two strips of flexible ma 6o terial attached together and having out weirdly-extended flange portions secured to the top and bottom of the body portion, as shown at the left-hand side of Fig. 2, or they may consist of single strips having flange portions attached tothem and secured to the body portion, as indicated at the right-hand side of Fig. 2. The partitions 2 and 3 serve also to prevent the raft from assuming a ball or bag shape when inflated.

Arranged longitudinally on opposite sides and at the outer portion of the body portion are pockets 5 for containing cork or similar material 6, and at the central portion, at each side of the raft, is a pump casing or receiver 7. This pump casing or receiver is closed at its ends and inner side, but open at the outer side. From the ends of the pump casing or receiver pockets 8 are extended parallel with the pocket 5, and they have their ends and rear edges secured to the material of the body portion in any desired manner. The inner ends of said pockets are secured to flange portions 9 on the end walls of the pump casing or receiver. Blocks 10 of cork or the like are arranged in the pockets 8, and these pock= ets and cork fillings areheld rigidly by means of ropes or similar connections 11, which at one end pass through openings in' the end walls of the pump casing or receiver and are enlarged at the inner end to prevent them from slipping through said openings, and at the opposite or outer ends the ropes are connected to screw-rods 12, which pass through brackets 13, attached to the body portion, and 5 adjusting-nuts 14 engage with the screw-rods at the outer side of the brackets, as plainly indicated in the drawings. Obviously by manipulating these nuts 14. the cork blocks will be clamped closely together and the parts will 10o beheldsubstantially rigid. Attheoutersides of the brackets I preferably place a filling 15, of granulated cork.

Extended through the inner wall of the pump casing or receiver and communicating with the interior of the body portion is a tube 16, which communicates or is connected to a cylinder T-head 17, provided with an airinlet opening 18 at its top. In Fig. 8 I have shown heads 19 for the T as engaged therewith by screw-threads. The heads, however, may be secured in place by means of a bolt 20, as indicated in Fig. 7.

Mounted to swing on the T 17 is a pumpcylinder 21. This pump-cylinder 21 is connected to a tube 22, which has a collar 23 surrounding the T 17, and this collar 23 has an opening 24 at one side, so that the pump may be swung downward. The opposite side 25, however, is closed, so as to close the opening 18 to prevent an escape of the inflating me dium when the pump is turned downward in the casing. A spring 26 is attached to the sleeve 23, and this spring has a pin 27, adapted to engage in perforations in the upper side of the T 17 for the purpose of holding the pump in a vertical position when in use and also to engage in a perforation formed in the side of said T to hold the pump in its position in the casing.

hen the pump is turned into the casing, it rests upon a yoke 28, attached to a screwblock 29, engaging in a tubular boss 30, commu nicating with the interior of the body portion, so that by removing the said block 29 the body portion may be deflated. A perforated piston 31 is operated in the pump-cylinder by means of the piston'rod 32,- and on the lower side of this piston 31 is a flexible disk valve 33. Arranged at the lower portion of the pump-cylinder or barrel is a perforated disk 34, forming the seat for a flexible valve 35, which is attached to said disk by means of a bolt or screw, as plainly indicated.

When preparing the device for use, it is obvious that it may be inflated by operating either one or both ofthe pumpsthat is, while the raft is on board a Vessel or the like. \Vhen the device is afloat, however, the pump at the upper side will be used for inflating, if found necessary. Life-lines 36 are shown as secured to the opposite sides of the raft, said lines being connected to the several pockets, as indicated in Fig. 1. When the device is deflated and not in use, it may be rolled compactly together for storage or transportation.

In the modification shown in Figs. 14, 15, and 17 I have shown in addition to the cork filling for the central pocket 8 metal or wood plates 37, which extend from the ends of the pump-receiving casing to the ends of the pocket. These plates are tapered from their inner ends downward toward their outer ends, and the plates are secured to baseplates 38 by means of screws or otherwise,

these base-plates 38 also extending throughout the length of the pocket.

In Fig. 16 I have shown a side pocket 39 as made cylindrical throughout its length and attached to the bodyportion 1 by means of a web 40, the web 40 being of sufficient width to allow the pocket containing the cork to swing laterally.

In the modified form of pump shown in Figs. 18 and 19 the upper portion of the tube 16 has a projection 41, one surface 42 of which is made flat to receive a corresponding surface 43 on an extension 44 of the pumpbarrel. The plate or surface 42 is provided with opposite triangular ports 45, while the plate or fiat surface 43 of the extension 44 is provided with triangularports 46. The pump is mounted to swing on a bolt or rod 47, extended through the said extensions 41 and 44, as plainly indicated in Fig. 18. In this device when the pump is turned to a vertical position the

ports

45 and 46 will register, so that air may be forced into the body portion.

When the pump-barrel, however, is turned downward, as indicated in dotted lines in Fig. 19, the solid portion of the plates or surfaces will act as closures for the ports. The pump may be held in its vertical position by means of a spring 48, attached to the pump and adapted to engage with its free end between lugs on the upper end of the extension 41.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Alife-raft, comprising an inflatable body portion, pockets arranged on the opposite sides of said body portion, cork or similar material in said pockets, and inflating-pumps on opposite sides of the raft the said pumps being mounted to swing relatively to the raft, substantially as specified.

3. A life-raft, comprising an inflatable body portion, pump casings or receivers arranged on opposite sides thereof, pumps mounted to swing into and out of said receivers,and means operated by the inward swinging motion of the pumps for closing the inlets to the body portion, substantially as specified.

4. Alife-raft, comprising an inflatable body portion, cork floats secured to opposite sides thereof, tubes communicating with the interior of the body portion, cylinder T-heads on said tubes and having openings at the top for the entrance of an inflating medium, and pumps mounted to swing on said T-heads and into casings adapted to receive them, sub stantially as specified.

5. A life-raft, comprising an inflatable body portion divided into compartments communicating one with another, pump casings or receivers located on opposite sides of the body portion, pumps mounted to swing into and out of said casings, means for securing the pumps in either one of their adjusted positions, yokes in the casings or receivers upon which the pumps may rest, and screw-blocks attached to said yokes and normally closing the outlet-openings of the body portion, substantially as specified.

6. Alife-raft, comprising an inflatable body portion, parallel pockets arranged on said body portion at opposite sides and spaced apart, cork fillings for said pockets, and an inflating-pump mounted to swing relatively to the body portion, substantially as specified.
