u BULLET-racer mon. i

To all lwhom t concern.' A i? c Be it known that we, THEoDoRE DE DRAGIC and ALBERT SCHWARZ', both subjects of the Kfin of Servia, and residents of the borough o York, have; invented certain new and useful Improvements in Bullet-Proof Armor, of which the following is a specification.

This invention relates tobullet proof armor. The invention is especially useful in bullet proof armor to be worn on the body.

Various kinds of armor to be worn on the body, 'including bullet proof armor, have been proposed from time to time, but a study of the matter and our experience with bullet proof armor has taught usthat wherever such armor has been made reliably bullet proof, it has comprisedl so much' material that it was intolerably heavy and `bulky to be worn as a part of an already heavy equipment, or to permit the freeuse of the-body in fighting, and where it .has .been made light and compact enough to permit it to be carried as a part of a soldiers equipment, lit hlas not been sufficiently nexible and reiab e.

Bullet proof armor Afor a soldier must be suciently compact and flexible so that itr will not interfere with his other equipment that he mustcarry and use in marching and l fighting, andmust not unduly interfere with hls agility or the free use of his body or arms in fighting; and it must be suiiciently light so that it will iot overtax him and thus cut down his endurance in fighting; and the same is true--at least to a large extent-of bullet proof armor to be worn by policemen in riot work andthe like. While they have not marching to'contend with, they are frequently brought into closer rough and tumble fighting, and must be able to freely use their arms and weapons and give chase whennecessary, even in a manner that a soldier is not called upon to do. So that it becomes essential for albullet proof armor tol be worn on the body for such uses, that it shall be of minimum weight compatible with a safe margin as-'to its bullet proof qualities. Y

The object ofour invention lsvto provide a reliable, thoroughly bullet proof armor to A be worn on thefbody, which is amply light and exible enough to be used b soldiers and policemen wlth'out u'nduly vurdening them with weight, and` without impeding Specification o!

The invention consists in the novelfeatures, arrangements and construction of parts hereinafter described in connection with the preferred embodiment thereof, and the invention will be more particularly pointed out in the appended claims. Referring to the drawings- Figure 1 shows a front view of a mans body having our preferred form of bullet proof armor. iittedthereto;

Fig. 2 is a back view of the same;

*PATENT oFl-lcE/f l Patented Nomea, 1921.

Fig. 3 is an enlarged sectional view takenv on line 3-3 of ig. 1, with certain parts broken away an the armor plates removed for the sake ofclear illustration;

Fig. 4 is an enlarged face view of a series of pockets containing armor, with a part` of one of the retaining pockets broken away to show the interior construction; y

Fig. 5 is an enlarged view taken on line 5`5 of Fig. 4, with certain parts broken away; and

Fig. 6 is a front view similar to that of Fig. 4, with a part of one of the retaining pockets torn away showing a modied form of armor plate.

Y Referring to the drawings, the complete armor jacket or form consists of a series of envelops .1, 2, 3, each carrying a suitable bullet proof armor and secured preferably at their fupper edges only, as shown at 4 (Fig. 1) to a sheet of iexible material 5 (see Fig. 3) suspendedfrom the shoulders by 'stra s 6 se i connected to a rear envelop 7 exten ing a down the back and alsocontaining armor, Vherelnafter described. To the rear envelop 7 is stitched side protecting envelope 8, 9 to l the front ends of which are secured straps 10, 11 having buckles 12, .13, for buckling the side envelops in across the front.

In order to put on the armor form or jacket, it is only necessary to slip the head between the shoulder straps and buckleV the straps 10 and 11 across the front of the body.

Referring to the arrangement and construction of the envelops 1 2, 3, this is bethere 5 represents i ter illustra' fl in Fig. 3, w i a strip of nexible material, Vpreferably 1n the form of a sheet, of coarse muslin hung down from. the shoulder strap` 6 and'l to` which the envelov s1',f2, 3- are sewnat their upper edges, as s own at14,15, 16. Within ea 1; of these envelope is sewn at the `top thereof, a flexible armor support 17 prefer-` ably made of stron textile fabric, or of a combination of fabrics such as thin felt and coarse muslin stitched together. The envelop 1 is preferably sewed at its top to the armor support 17, and then the Acombined ends are sewed to the flexible support 5 as at '14. To the support 17 in turn is sewed a series of armor-carrying pockets 18 which ma be made of muslin, shown more clearly in igs. 4 and 5 and indicated by shading in'Figs. 1 and 2. The envelops 1, 2, 3 are preferably secured to the .'-ffront support 5 only at their upper portions, so that as the body bends backward or forward, the envelops are free to move one wlth respect to the other, the lower end of one sllding over the other or swinging out therefrom, according to themovements of the body, so as to give the utmost feedom of movement of the bod In this way also the parts may be rea 'ily put together. The successive envelops voverlap just suiiiciently to 'insure overlapping of the armor so as to prevent the penetration of a bullet 1n between the u per extremity of one envelop and the lower extremity of the next one above 1t. Either the containing envelops, such .for example, as 1, 2, 3, etc., or the indlvidual armor-containing pockets 18, may be made of some moisture-proof material such as oiled linen or the like, in order to protect the armor plates from rusting due to water or perspiration.

Referring to Fig. 5, it will be seen that the individual armor-containing pockets 18 when arranged as shown in thisfigure, are` sewed at their upper ends as at 19, 19', etc.,

to the flexible armor support 17, which inthis case is shown as consisting of a thin layer o f felt 20 and a layer of muslin 21. Each of the individual pockets may be made of muslin, and the pockets are each substantially filled by a sheet of suitable bullet proof armor hereinafter more fully described. The pockets as shown are stitched preferably only along one of their longitudinal edges to the armor support 17 so as to permit free movement of the pockets one with respect to the other with the move- 'ments of the body. The pockets are arranged shingle-like in such'manner as Ato always present at least two thicknesses -of the bullet proof armor at any point. In the case of the back envelop 7, the individual armor containing pockets are arranged invertical alinement one above another, and are stitched at their upper edges as shown in Figs. 2 and 5. I-n the front envelops 1, 2, 3 and in the side protecting envelops 8 and 9, the individual armor containing pockets are likewise arranged shingle-like one overlapping another, but in this case they are".

arranged in horizontal alinement and are secured along one of their longitudinal edges only so as to allow these envelops as a whole to readily conform to the rounded contour of the chest and sides. It lwill be understood that the individual pockets may be stitched to their support otherwise than at their edges, and lmay be stitched one to another, provided the arrangement is such asV to permit suicient iexibility. But it is far more advantageous to have these armor containing pockets free to move one over the other by securing them lJnly along one of their longitudinal edges.

Referring now to the bullet proof armor itself, this may for lcertain purposes consist of any suitable hard thi/n metal useful for bullet rotection, but we prefer to use plates of higii shown at 22 igs. 4 and 5) or to use plates of highly tempered sheet steel woven of strips of relatively narrow thin sheet steel such as shown at 23 in Fig. 5, and in each case, the steel plate, whether solid or woven, is wrapped or padded with suitable layers of textile materlal as for example by bein wrap ed with str1ps of cloth such as sil 24. here the solld sheet steel 22 is used, we prefer to use what is lmo'wn in the trade as wedish 'blue tempered steel or Indiana straw tempered steel, of a .thickness of .02 inches, and we use pieces of this approximately 2 inches wide to place in the pockets, the strips and pockets being of such length as to conform to the shape of the enevlops to be worn on the different parts of the body. Where the plates are made up from the woven steel strips, we prefer to use the same steel but of a thickness of only .O12 inches and in such case to either place two of the wrapped plates in each pocket or else always use two pockets together side by side instead of one, such as is shown in Fig. 6. We prefer to wrap the Steel plates to such an extent that the total thickness of the entire bullet proof armor-4I. e., the wrap ed plate, is about of an inch. Where silk is used as the wrapping instead of other cloth such as drill or muslin, the thicknessneed not be so great, because the silk is more efficacious, when used in conjunction with the steel plate, in preventing penetration of the bulet, than 1s the case with cloth that does not present a slippery or so-called frictionless surface which seems to have the eifect of turning or diverting the course of the bullet upon contact therewith.' i

The armor jacket when made up complete, including front, back and side protectin envelops, as shown and described, lusing sil wrapping, weighs'only about 11 pounds, and is therefore suiiciently light to be utilized by soldiers and policemen.

While, for the sakelof those Skilled in the art, we have described our invention in great v detail in connection with what we now believe to be the preferred embodiment thereof, it will be obvious to those skilled in the art, after understanding our invention, that various features of construction and relative arrangement and location of theparts may be made, and that certain features or parts may beutilized without others, without departing from the spirit or scope of our invention, and we do not wish to be understood as limiting ourselves other than as indicated in the appended claims;

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:
