IMPROVEMEKT m mrn-eansnnvnns. W.
The Schedule referred to in these Letters Patent and making part of the same I, LYMAN Jsoons, of ,Albion, Calhoun county, in the Stateof Michigan, have invented certain Improvements in Liie-lireservers, of which the following is a specification.
Nature and Objccls of the Invention. The nature of my invention consists in so adapting suitable mechanism to a water-proof casing for the employment of two ball-valves located ina cylinder,
the one above the other, and connecting with the interror of the casing, by means of which the impure atmospherc may be ejected and the pure admit-ted, at the same time that the water is prevented from entew ing therein.
Description of flu; Accompanying Drawings.
Figure 1.is a plan view of my life-preservcr. Figure 2 is a-plan view of the-cylindrical valve rcceptacle G..
Figure 3 is a plan view of the cylindlical valve reof the body being inverted in the water bythe force lot a heavy wave.
Figure 4 is a vertical section of the combined rah ular device.
A is the casing for the body, which is shaped from the arms down, to the feet, inclusive, to correspond with the form of" a man, but made large, to permit its being easily put on the body, and the armlets made from the hand to reach above the head, of a width and shape corresponding with the dotted lines 3 s and thelines of the arms H; and said casing or covering for. the body can be made of any other well-known waterproof material.
a a, are the legs or boots of the casing, the lower portion of which are provided'with weights rigidly s'coured thereto at a. r
The infolding of said casing may be prevented to a greater extent than as shown at 13,-by the steel pieces (I.
B is that part of the casing or covering which en-' outer cas ng; the whole is then inserted as aforesaid, and the outer and inner casing securely ihstened'to; gether. Said strips project vertically from the upper part of the chest (1, above the head to the point (1.
O G are floats, which may be made of cork, and sccured to the casing so as to cover the Pack oft c hand, and are comprised of a nhmber small pieces, so
united togetl'ier as toiadmit of the opening and closing,
of-the hand. I
13 It represents two glasses or goggles provnledin the casing for the purpose of vision, which are firstmserted in metallic plates, the latter being riveted to the casing, or otherwise constructed in any of the forms which ordinarily obtainin diving armor, and others may surround the-head. I F is a .float or life-preservcr, secnreiy attached to the casing, on the exterior thereof nd located immediately underneath the arms at the 1p1ts. It may also be made elastic, or otherwise J bad to ht the body very closely, in order the better to prevent the possible escape of air from the upper part to that part of the body of the device below the float aforesaid. However, said tightening ,of the float 1 to prevent the passage of air to that part 'of the casing which 1s located beneath or lower downthan the same, is only requisite in the possible contingency of the position G is a cylindrical receptacle of a hsil valve, having the pipe 6 leading therefrom into the interior of the casing aforesaid, to a point in close proximity to the month of the individual encased.
g is a concave ball receptacle, located. in the cylinder G, the ball p rcmail'iing'in the concavity thereof when at rest.
The interior or central portion of said ballp is com posed of lead or other heavy metal, which 13 covered with India rubber, in order the better to present an elastic surface for closing the orifice c of the cylinder or pipe loading inside of the casing to the mouth of the person inca-sed in the life-preserves; but said pipe can only be closed momentarily, and when time closed will iuclose inside the casing an ample supply'of atmospheric air to supply the wants oi the individual incascd.
The, cylinder G is provided with the flange H, which is riveted to the rubber casing.
The cylinder G is rigidly attached to the cylindrical receptacle I, as shown in fig. 4.
I is a continuation of the cylinder of the valvnlardevice, and is provided with a ball, located in the lllinterior thereof, and resting upon the bars K K, which are crossed or intersect each other. q
Cylindrical receptacle I has projecting irom thenpper part thereof a funnel, f, corresponding m width G, in which it is located, and
ameter of the pipe e1 The upper part of the interior of the framei is com cave, and so adapted to the convexity of the Indiarubber ball'i, as that when the latter impinges against the same, the orifice o of the funnel is closed tightly and prevents 'the.ingress oi" water. Si id cylindrical or valvular device may he made either metallic or of gutta-percha, and riveted, as shown at z, to the rub her casing, or it may be permitted to" swing loosely, attached to the casing at H, as aforesaid.
It will be observed, from the above-described construction of the valvular device, that this life preserver is adapted not only to meet the requirements of such an article in calm waters, but more especially for those the most boisterous, and that the'clastic hollow hall nearest the water is yet elevated to such aheight he raised from the cross-bars when acted upon by high above itthat it will only K K, on which it rests,
, waves, and that, as the waves in their action are intermittent, the intervals will afford ample time for the inhalation of pure atmosphere and .the exhalation of that which has been breathed into the lungs.
device, shall he snfiicient to always hold the'body' in an erect-position said contemplates the possible mentary inversion of the body, in the most turbulent or stormy sea, in which event the upper or weighted ball 1), being heavier than the water, would close the upper valve, it off from in grass into the rubber casing,
