A. DEsJARLAls ETAL LIFE PRESERVER Filed' Aug. 414. 195s July 21, '1959 2,895,147
LIFE PRESERVER Arthur Desjarlais, Springfield, and Frederick E. Desjarlais, Agawam, Mass.
This invention is concerned with improvements in life preservers and has for its principal object a means for providing a person with a light weight automatic or manual type of life preserver that will keep the person afloat.
Heretofore life preservers have been found to be inecient in certain details of construction and in the cost of manufacture.
It is a principal object of the within invention to provide a life preserver that has certain features that make for low cost production.
It is yet another object of the within invention to provide a compact life preserver which may be inllated manually.
It is still another object of the within invention to provide a life preserver that has a novel means for securing an automatic valve for releasing a cartridge of compressed gas into the inner circuit of the life preserver.
It is yet another object of the within invention to provide a manual type valve means enabling the user to blow air into the inner circuit of the life preserver.
These and other objects are attained by the use of a high pressure tank valve that is connected in parallel with a mouth valve and in circuit with a pair of water wings.
With the foregoing and other objects in View, the invention consists in the construction, combination, and arrangement of parts hereinafter described and illustrated in the drawings in which:
Figure 1 is a perspective View of the assembly with the tank valve and mouth valve in the foreground.
Figure 2 is a side elevation of the life preserver shown in perspective in Figure 1, in open position.
Figure 3 is a semi-schematic diagram of the air circuit of the life preserver.
Figure 4 is a perspective view disclosing the novel means for securing the tank valve assembly to the life preserver belt.
The buckle 1 is of the conventional type and has inserted therethrough the leather belt portion 2 of the life preserver belt. The aps 3 conceal the water wings 4. The water wings 4 are identical with the water wings as disclosed by our Patent #2,716,245. For this reason, explanation of the way the flaps 3 conceal the folded water wings 4 is felt to be unwarranted.
Mounted also in the belt is a tank valve assembly 8 which is disclosed in detail in the patent of Arthur Desjarlais, one f the inventors herein, Patent ttf-'2,749,079 Because this valve assembly 8 is so well taught in the said patent disclosure, it is also felt that any detailed description of the valve assembly 8 is unwarranted in this instance.
A valve 10 which is of the manual type is mounted also in the belt. lt is mounted in the cloth section of the belt which is referred to as the numeral 29. This valve 10 is also disclosed in our Patent #2,716,245 in Figures 14, l5, 16, and 17 and for this reason it is felt that a detailed description is unwarranted.
United States Patent() Reference is made particularly now to the air circuit shown in Figure 3. As can be seen the automatic valve assembly 8 with its automatic valve knob 7 is secured to an L-shaped tubing 12 to the valve outlet coupling 11. The L-shaped tube 12 is secured to a T connection 13. The T connection 13 has the conventional anges 30 secured thereon to prevent slipping and to make a better connection to the inner hose 26 of the air circuit.
The hose or tubing 26 connects from one side of the T connection 13 directly to one of the bladders 5. The other side of the T connection 13 is connected by the tubing 26 to a T connection designated as `14. At the top of the T connection 14 is a vertical hose or tubing member 9 which interconnects the T member 14 with the manual valve 10. At the far side, opposite from the automatic valve assembly 8, is another section of the tubing 26 which interconnects the T connection 14 with the other bladder 5. The bladders 5 are of course covered with the cloth material 4 similarly as discussed and disclosed in our Patent Number 2,716,245. The air circuit or tubing 26 is covered by the cloth material 29.
One of the problems that had to be overcome in arranging the life preserver of this invention was the mounting of the valve assembly S in the cloth structure 29 of the life preserver. It is to be understood that the valve assembly 8 utilizes compressed gas which is stored in a small tank 27. The tank 27 can be unscrewed of course and replaced by a full tank when used. With these problems in mind, it became necessary to make an arrangement that adapted the device to be easily replaced as shown in the view of Figure 4.
Secured to the belt material 29 is an aluminum fastening block 20 which has a concave surface to receive the cylindrical shape of the tank 27. In the embodiment disclosed, the block 20 was sewn by thread 22 to the belting material 29. The block 20 was therefone designed with an elongated slot 21 through which the thread 22 could be secured to the belting material 29. However, it is contemplated that in mass production circular openings may be used in place of the elongated slots 21 and that a riveting machine could easily be employed to rivet the block 20 to the cloth material 29. Connected to the block 20 is a holding clip 23 which circurnscribes the circular portion of the tank 27 and it locks into the block at its far end by the screw 25 in the opening 24. The block 20 has beneath the screw 25 a threaded opening, which is not shown but which is conventional. This threaded opening receives the screw 25. At the bottom of the tank 27 is the conventional safety valve 28. In placing the tank into position, foresight for the possible blow otf of the valve 28 had to be planned. Therefore the design of the liap 15 was devised. The flap 15 is a piece of cloth that has the female snaps 16 along with the male snaps 17 and when placed over the tank 27 conceals same but leaves a small opening between the flap 15 and the fixed portion 6 which is behind the block 20 and is also sewn or riveted to the belt material 29.
Reference is again made to the view of Figure 1 in which the valve assembly 8 is disclosed. It is to be noted that extending from the valve assembly 8 is the valve stern 18, which interconnects the coupling 11. A clamp 19 securely fastens the L-shaped tube 12 to the auto matic valve assembly 8.
The user who desires to release the gas from the tank 27 merely opens the tank valve knob 7 until the gas from the tank 27 is released and passes into the air circuit as disclosed in Figure 3, whereupon the bladders 5 are inflated. It is to be noted of course that the mouth valve 10 must be secured and closed so that the air will not be released.
To inflate the bladders 5 by mouth it is best to close wings, a hollow air tube, a rst T-connection, an L- to the other water wing, said water wings being mounted shaped air tube having one end connected toone end Y,
of the T-connection, a tank valve assembly, a source of air in said tank valve assembly, an outlet from said source of air, said outlet connected to the other end of the L-shaped tube, one segment of said hollow tube connected to a second end of said T-connection and to a water Iwing, a second segment of said hollow tube connected to said third end of said T-connection, a second T-connection, a mouth valve connected to one end of said second T-connection, said second segment of said hollow tube connected to the second end of said second T-connection, a third segment of said hollow tube connected to the third end of said second T-connection and on a belt, said hollow tube segments being within the belt, a mounting block attached to the outside of said belt, a clamping means for securing said tank valve assembly to the block, the contacting surface of said block compleinenting the contour of the contacting surface of said tank valve assembly, and a ap means for covering the said tank assembly.
