BROTECTIVE AND NON-PENETRATIVE COVERING AND THE LIKE.

No Drawing. Application filed May 18,

To all whom it may concern: 1

Be it known that I, GEORGE LYNCH, a subject of the King of Great Britain, residing in London, England, have invented certain new and useful Improvements in Protective and Non-Penetrative Coverings and the like, of which the following'is a specification.

This invention relates to improvementsin protective and non-penetrable coverings and the like adapted to be employed for'many military and other purposes.

I have found that if wool or cotton wool is impregnated While in its normal loose or flufl'y condition 'with' dry powdered resin which is sticky oradh'erent at normal temperature it becomes, while retaining its normal loose or flufly condition more or less points of barbed wire, bayonets or the like, and stops or very materially resists the passage of flying articles, suchas bullets, shrapnel and other similar flying fragments.

My invention therefore consists essentially in a protective and non-penetrable' material comprising wool, or cotton wool, in a normal loose or fiufly condition impregnated or treated with resin in a dry powdered form which is sticky or adherent at normal temperatures and is also preferably insoluble.

In carrying out the invention the wool or cottonwool is treated or impregnated with the powdered resin by dusting it in between the fibers in any suitable or convenient manner. The resin may for instance be sprinkled or blown over onzirito the fiber, the sprinkled or treated fiber-being subsequently passed through rollers or beating or tapping means by which the powdered material is pressed or shaken well among the'loo-se fibers and into or into "intimate contact with the fibers Specification of Letters Patent.

fiufl'y character with the dry powdered resin 5 wire entanglements and over which the soldiers can readily pass without receiving a scratch, or the material may be made ,up into gloves for the handling of barbed wire.

Sheets such as above described may also form ground sheets for the men or-by lacing them together along two edges and an efid mate. Or the material may be made up into uniforms, clothing, Helmets, gauntlets, leggings or the like, and will give protection against, bayonet' thrusts orthe like and against shrapnel, bullets or other flying fragments. It is not wholly impenetrable by bullets but it very materially retards' their passage. Or it; may be used for armoring aeroplanes, guncarriages, motor cars or the like, providing an inexpensive and light method of doing this, the material being mounted or supported. in any suitable bags which manner on a metal or other framework with h or without a sheet metal orv-other backing. Or the treated woolly fiber may be introduced into a light metal or other receptacle forming a sort of jacket to receive it and constructed of the desired shape andsize to form the armoring.

In any case in which wool isinclosed in coverings or envelops o the wool or cotton of the'woolly material yet without causing .textile fabric, the sheets forming such'covthem to adhere or without impairing the normal loose or flufi'y condition of the material. Or the powdered resin may be introduced during the manufacture of the sheets, or laps of the fibrous material. For instance in the manufacture of cotton-wool where the final sheet consists of a number of separate laps or sheets superimposed upon .one another the powdered resin may be blown or dusted between the several sheets before they pass through the calender rollers adapted to unite the'separate laps into one.

erings or enveldps will have their securing stitches or seams spaced at such intervals as may be necessary to preserve the normal loose and flufly condition of the' material.

It will be obvious that the material may also be employed for many other analogous purposes. 0

Having thus'described the nature of the said invention and the best means I know of carrying the same into practical efibct, I claim i 1. As a new article of manufacture, a pro- In any event the finished product should ,tective and bullet-impeding material for use be Wool or cotton wool of normal loose or in military operations comprisi g a Sheet quilt of wool or cotton wool in a normal loose or. flufl'y condition impregnated throughout its extent with dry powdered resin.
