Bagdassarroif, also known as Martin L. Springer, Box 891, R.F.D, 2, Riverhead, N.Y. Filed Oct. 14, 1963, Ser. No. 316,053 3 Claims. (Ci. 9-400) This invention relates to lift raft or life preserver means for boats and more particularly for means for ejecting life preservers from boats in an automatic manner.
One of the main hazards in the operation of boats, especially small boats, is the danger of tire and explosion from gasoline fumes gathering below decks. Gasoline fumes are heavier than air and settle down at the bottom of bilge space in the boat. -A cup of said gasoline fumes, if ignited, will blow apart any small boat. When such a thing happens the occupants of the boat generally do not have time to get life preservers. As a matter of fact, they are generally blown overboard by the force of the explosion.
The present invention provides means for automatically ejecting inatable life preservers such as small rafts. Means are provided to actuate the ejccting means automatically upon explosion, or fire, as well as manually. The automatic control means, which may be various switches, are spaced throughout the vessel at points of hazard.
More particularly, the invention comprises a container means for the inflatable life raft which is iixedly connected to the boat. The container has a piston and the piston is adapted to be actuated by a firing mechanism which may be a detonation device, a spring gun or other equivalent apparatus. The life raft is of the type having a cartridge of compressed gas, and it is rolled up and placed in the container over the piston.
Then, in the event there is any lire or explosion, the piston is fired and the life rait is ejected a convenient distance for instance 20 feet, so that anyone who is thrown or jumps oi the boat may easily get to the life raft without any diiculty. Means are provided for automatically causing the compressed gas cylinder to inflate the life raft upon the ring.
Accordingly, a principal object of the invention is to provide new and improved life raft means.
Another object of the invention is to provide new and improved means for automatically ejecting life preserver means for boats.
Another object of the invention is to provide new and improved means for automatically ejecting life preserver means from boats comprising la life preserver and gun means which are adapted to re the life preserver a substantial distance from the boat.
Another object of the invention is to provide new and improved life preserver ejecting means which are responsive to explosion and heat on a boat.
These and other objects of the invention will become apparent from the following specification and drawings of which:
FIGURE 1 is a diagram illustrative of the use of the invention.
FIGURE 2 is a side sectional view of an embodiment of the invention.
FIGURE 3 is a top view of the embodiment of FIG- URE 2.
FIGURE 4 is a schematic diagram illustrating the control means of the invention.
FIGURE 5 is a schematic electrical diagram of typical control means for the invention.
Referring to the figures, FIGURE 1 shows a rear View of a typical small craft 1, illustrating the location of the engine 2 and the location of the ejecting means 3 and 4 of the present invention. The arrows 5 and 6 illustrate the trajectory of the life preservers when tired by the ejecting means 3 and 4.
3,175,23h Patented Mar. 30, 1965 ICC FIGURE 2 shows a detail sectional view of the ejection means which generally comprises a cylindrical container 3', which may be of the order of size of a live gallon tin can container, that is approximately one foot in diameter and 21/2 to 3 feet high. This size should be adequate to contain a two man life raft 7, when rolled up in a noninliated condition. At the bottom of the container 3 is a piston 8 having a shaft `8', which fits into a firing cylinder 9. At the bottom of the cylinder 9 is an ejecting means `lt) which may be an explosive charge for instance a shot gun type shell with suitable firing pin.
Alternatively, the ejecting means lll may be a triggered spring, or compressed gas, or equivalent conventional force applying means. The bottom il of the container should be a substantial piece of steel to absorb the explosion or reaction force of the ejecting means.
The force applying ejecting means lil, is adapted to be red or triggered preferably electrically, by means of the conductor l5 which is connected to a series of control switches as will be explained. The switches are responsive to heat and explosion. Manual control switches are preferably incorporated for manual control. These switches are preferably located around the boat at points of danger for instance in the engine space, in the bilges, in the galley near the stove, and in the cabin space.
FIGURE 4 shows the container means 3 and 4 located near the stern of the boat l. The containers are connected by electrical conductors `l5 and 16 to the ejection control means i7 which may be centrally located. The ejecting means is connected to a plurality of switches 1S, 19, 2li, and `2d and so forth, which are located at strategic and convenient locations throughout the craft for instance, in the engine space, bilge space, galley, stove, and so forth. The containers are set at an angle to the vertical for a good trajectory away from the boat.
FIGURE 5 shows an electrical circuit diagram with typical control switch means :18, 19 and so forth. Each control means may comprise a plurality of switches connected in parallel, one switch 20 may be a bi-metal switch which is adapted to make contact very quickly upon the application of heat. `Connected parallel thereto may be a switch 21 which has a seismic mode of operation, in other words, being responsive to explosion. The switch may be constructed by having a weight 22 on the end of one of the spring contacts 23. Connected in parallel thereto is connected a manual switch 2d which is accessible to anyone close by.
The ejecting means 3 and 4 may be placed at conventional locations throughout the craft. The stern may be in a convenient location and the containers may be positioned so that the life preserver is ejected over the stern or" the boat. This would be a good arrangement in case of a man overboard when the boat is underway.
The size of the ejecting container or gun would depend upon the size of the life preserver. For a small craft, a two man life raft may be rolled up and inserted in a container about one foot in diameter and two to three feet ong.
Larger vessels would require larger sized life rafts and correspondingly larger container guns.
This device would be quite useful for launching life rafts under bad sea conditions, when quite often conventional life boats are not able to be lowered. For instance, the ship may be listing so heavily that conventional life boats may not be able to be lowered.
The container preferably has a cover 19' which has a relatively loose fit so as not to interfere with the proper operation of the device. The covers serve to keep the enclosure dry and clean.
The life raft package may include an emergency radio, first aid kits and even provisions if desired. A small radio transmitter of the type adapted to automatically It broadcast S O S. signals would be a desirable addition to the package.
More specifically referring to FiGURES 2 and 3, the life raft package includes a cylinder 25 of compressed gas for instance CO2 which has a valve 26 which may be opened by the static line Z7 connected to the cylinder 3' so that the cylinder will be opened as the package is ejected and the life raft inflated as it is ejected. Alternatively, the valve 26 could be triggered by a water sensitive device.
Additional equipment such as a radio transmitter 23 may also be included in the package. These devices Z5 and 28 are preferably inserted in special compartments or sleeves of the lite raft and their weight may be used to control the landing of the life raft in predetermined position so that it will iniate in tip-right position. However, this is not too impor-tant on small life rafts which may be easily turned over in the water, if desired.
Many modications may be made by those who desire to practice the invention without departing from the scope `thereof which is defined by the following claims.
I claim:
