Specification of Letters Patent.
Patented Nov. 20, 1906.
Application tiled June 14, 1904. Serial No. 212,677.
To all whom/ it may concern.- Be it known that I, EDWARD MoRBnLL, citizen of the United States, residing at San Quentin, in the county of Marin and State of California, have invented certain new and useful Improvements in Pneumatic Liie- Saving Suits, of which the following is a specification. My invention relates to an improved pneumatic life-saving suit, the object of my invention being to provide a pneumatic suit adapted for saving life at sea.
My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends, hereinafter fully s ecified, and c aims. I
In the accompanying drawings, Figure 1 is a front elevation of the device. Fig. 2 is a vertical section of the same. Fig. 3 is an enlarged vertical section of-the upper portion of the pants part of the device, showing their mode of union. Fig. 4 is an enlarged detail sectional view of the pump or bellows for supplying air to the pneumatic compart- Fig. 5 is a similar view of thecheck- Fig. 6
ments. valve for one of said compartments.
' is a detail erspective view of the breathing tube or bu b.
Referring to the drawings, 1 represents the upper or shirt part of the device, and 2 the lower or pants part. Bothoithese are made of the best quality of indie-rubber. They are connected for use in the following manner: A metallic shirt-waist band 3 is riveted to a metallic inner waistband 4, clamping therebetween the lower edge of the shirt part 1 of the device and of the lower lining or casing 5 of the pneumatic compartments of the shirt-waist portion. This upper shirt-waist band is circular and has a flange 6. 7 represents the lower or pants waistband, also made of metal, between which and the inner lower waistband 8 are clamped by rivets 9 the upper edges of the lower or pants portion 2 of the suit and the inner liningor sides 10 of the pneumatic compartments of the lower portion. This lower waistband 7 is threaded,
as shown, and between the up er edge of said lower waistband and the ange '6 is a rubber washer 11. Around said threaded portion is a coupling-band 12, having handles particularly pointed out in the 13, by which it can be turned, and having a shoulder 14, which bears down upon the flange 6, so that by turning the cou lingband on'the threaded portion of the lower waistband said washer is clamped firmly between the upper and lower waistbands and the suit is made thoroughly tight. The method of connecting the two portions of the suit ma y, hovve ver, be varied without departing from the spirit olf my invention.
'16 is the helmet or head-piece of the suit, made of heavy rubber, about one-eighth of an inch thick or more, to secure protection from the force of the waves, wreckage, &c. It is fitted with two eyeglasses of suitable size. tached to the suit, by a small chain 17, a bell-shaped air-bulb 18, about three inches in maximum diameter and three and onehalf inches in maximum length. This bulb has a perforated back 19, to which is coninches long, which when the bulb is in use fits into a metal screw-plate 21. This airbulb serves as a mouthpiece to the helmet when the wearer is floating in a heavy sea;
by the chain during a calm and when to veying food and water to the mouth. "17....
is adapted to cover that portion of the face around the screweplate in order to deflect the water oil when it splashes over upon it. The air-perforations .are located on the inner side about one and one-half inches preferably. The shank of the breathing-tube 20 is adapted to enter the screw-plate at the mouth and is nipple-shaped to' be inserted between the lips. Should water enter, it would be ejected by simply blowing it out;
Each part of the suit is divided into separate and independent air-compartments, so that in the event of any puncture of any section of the suit the buoyancy of the suit will not be entirely destroyed. These compart ments are shown at 21. ihe compartments are all connected separately with tubes 22, which may be either of metal or. of rubber. Each tube opens at its supply end into a bellows orpump 23, (shown in detail in Fig. 4,) consisting of a bell-shaped piece of rubber at- To facilitate breathing, there is at but it maybe unscrewed and left to dangle of the bulb and extend up from the base} nected a stiff rubber tube 20, about three base or perforated portion of the air-bulb 18 v check-valve is unseated by the spring, ad-
mitting air to the bellows.-
The pipe is connected by short pieces 27 with the inner linings or walls of the comp artments, the end of which piece having therein a spring-actuated check-valve 28, which permits air to enter from the pipe, but prevents passage of air from the compartment into the pipe. It will readily be seen that by moving the arms in and out air can be pumped from the outside into the compartments to keep them well filled, so as to give buoyancy to the structure. Each compartment being sepa rately attached to the pipe, the puncture of one compartment will not affect the rest.
Theupper inner waistband 4 has an annular tongue 30, which when the parts of the suit are put together enters an annular groove 31, formed by the lower inner waistband, thus guiding the parts into position. The tubes which supply the compartments are also in'two sections, one section 32 belonging to theupper or shirt part of the suit and the other section 22 to the lower or pants part of the suit. The upper sections have pointed ends 34, (shown in dottedlines in Fig.
3,) which fit within the funnel-shaped ends 35 of the lower portions, thereby making a tight fit when the parts are brought together.
36 represents ahorn, which may be blown to attract attention, and 37' represents a knife for defence or other purposes 38 39 represent pouches to contain foodtablets or medicines.
40 is a rope secured upon the handle of the device.
The'lowest compartments of all are adaptferred form of myinvention, it is to be under stood that the invention is not lii'nited to'the precise details herein shown, but may be variously changedin' form and structure with out dep arting'from the spirit thereof. I claim g 1.

4. A pneumatic life-saving suit divided into separate, independent air-compartments, so that in the event of any puncture of any compartments of the suit, the efficiency of the remainder of the suit will remain unimpaired, pumps or bellows located beneath the arms in position to be operated. by the wearers arms as they are raised and lowered,'tubes extending from the pumps or bellows to the various compartments and check-valves which permit air to enter the compartments and prevent its return into the tubes.
