Application led February 10,` I1923. Serial No. 618,229.

To all whom t may concern:

Be it known 4that I, LEO KRAUSE, a citizen of the United States, residing at New York, inl the county of `New York and State of New York, have invented new and useful prevent any discomfort and at the same timev effectively protect the body from injury by the impact of a missile.

An-object of the invention is to provide intermediate tenacious metal plates composed of a light metal of suiicient strengthto resist the impact of' a bullet. The metal is covered with a metallized ibre so that the heat from ay bullet cannot- 'set it onfire or moisture rust the plates.-

Another 4object of the invention is to arrange a quilted buffer between the metallized fibre and the plates=yvhereby the force of the missile is considerab y lessened before it impinges on the plat .i

The invention reside more particularly in the lnovel combination hereinafter de-l scribed an`d claimed, reference bein made tothe accompanying 'drawing in w ich:

Figure 1 represents a front elevation ofa shield embodying this invention.

Figure 2 is a vertical longitudinal section' of the same.

Figure 3 is a of the quilt.I

In the drawing the numeral 5 designates a series of metal plates made of. duralumin each plate being enclosed 'in a pocket 6-of fabric. The pockets partly overlap each other to produce a shingleformation and each pocket is fastened at its upper end by means of stitchesl 7 to a piece of fabric 8 located at the backr of the pockets.

perspective View of a portion Arranged at the front of the pockets is a quilted member built up of a stuin of raw China silk 9 covered with a metalized fabric 10 secured together by stitches 11 as indicated in Figure 3. A similar quilt 12 is located at the back of the fabric 8. On

each quilt is secured by means of stitches 13 a sheet of metallized vfibre 14 and a pair of shoulder straps lsupport the shield on the body.

In the drawing the invention is shown applied to a shield adapted to be worn under a coat but it will be obvious that it could be 'utilized for other purposes suchl as a cover` for the actuating parts of an aeroplane thus protecting it against gunshot.

The metallized fibre placed on the outside of the quilt is practically fire .and waterproof consequently a bullet fired from a gun at close range will not infiame the fibre nor will any moisture have' anyeffect on it. The stuffing is preferably composed of China silk which by its toughness and close comvpression will retard a missile. A bullet tired l at great velocity will merely embed itself in the metal aluminum and if it should go through it will be stopped by the quilt behind the plates. The duralumin is used in the present device because it is much lighter than any other metal so as not to add any undue Weight to the shield member.

I claim:

1. A bullet proof armor comprising a shield constructed of a series of tenacious metal plates lighter than steel, and a quilted member arranged vadjacent to the plates.

2. A bullet proof armor comprising a shield constructed of a series of metal plates, and 'a quilted member covering the plates.

3. A bullet proof armor comprising a shield constructed 'of a series of metal plates, a pocket enclosing each plate and a quilted member arranged adjacent to each pocket.v v

4. A bullet proof armor comprising a shield constructed of a series of metal plates,

vclosing each partly overlapping each other, a pocket en- Flate, and a quilted member covering the ront and back of the pockets.

5. Av bullet proof armor comprising a shield constructed of a series of metal-plates, a pocket enclosing each plate, a quilted member arranged adjacent the pla-tes, and a metallized fibre sheet secured to the quilt.

6. A bullet proof armor com )rising a shield constructed of a series of ralumn plates, a pocket enclosing each plate, a uilted member havin a stuffing of raw hina silk arranged ad]acent the plates, and a metallized' fibre sheet secured to the quilt'.

7. A bullet proof armor comprising a bre sheet secured to the outer side. 0f each' quilt.

In testimony whereof I have hereunto set my hand in the presence of two subscribing 10 witnesses.
