ELLIS s. OLIVER, OF NEWARK, NEW JEEsEr.

DETACHABLE FASTENING FOQR VACClNATlON-S H |ELDS.

BPEGIFIQATION forming part of Letters Patent No. 702,741, dated JuneilY, 1902. Application filed November 4,1901. Serial No. 80,998. (SpecimensJ Wakeman avenue, Newark, county of Essex,

State of New Jersey, have invented certain new and useful Improvements in'Detachable Fastenings for Vaccination and Analogous Shields, fully described and represented in the following specification and the accom panying drawings, forming a part of the same.

The object of the present invention is to furnish an inherently non-corrosive means for securing a vaccination-shield in a detachable manner, so that where adhesive straps are used to retain the shield in place they need not be'disturloed when removing the shield to inspect or treat-the sore.

The invention is practiced by providing the shield or straps with an inherently non-corrosive fastener bymea'nsof which the two can be engaged and disengaged at pleasure, and such anon-corrosive fastener is readily made of aluminium, which is inherently noncorrosive.

In a copending application I have claimed an inherently non-corrosive shield made of aluminium, and a metallic fastener of the desired character can beformed of tongues integral with such a shield and adapted to be bent over or under the straps to secure the shield detachably thereto. I

In other cases a staple-shaped fastener may be adapted to embrace the strap and project through holes in the shield, with the arms of such fastener bent upon the outer side of the shield, or it may be made like a McGill paper- -fastener,with its tongues inserted through the strap and shield.

Non-corrosive material like the metal aluminium furnishes a fastener which has no directly injurious efiect upon the skin and can be readily bent to engage or disengage the shield.

Several forms of the fastener are shown in the annexed drawings, in wh.ich

Figure 1 is a planof a shieldsecured to two straps by McGill fasteners; Figs2 is aside jected-from the outer sideof the strap. Fig. 5 is a plan of a shield and straps secured thereto by staple-shaped fasteners. Fig. 6 is a. cross-section of the strap and the shield ad- 'jacentto one of the fasteners shown in Fig. 5. Fig. 7 is a cross-section of one of the straps with the arms of one of the fasteners projected from its outer side. Fig. 8 is a plan-of a shield having integral fasteners and tapes securedthereby. Fig. 9 is a' cross-sectionof the tape and part of the'shield with the fastener formed as aprojeoting tongue, as shown upon the left-hand end of the shield in Fig. 8. Fig. 10 is a cross-section of the tape and part of the shield with the fastener formedof two tongues bent from slots in the shield, as shown upon the right-hand end of Fig. 8. Fig. 11 is a-perspeotive-vie'w of part of the straps applied to a wound,with fasteners projected outwardly from the straps, and a shield indicated by dotted lines; and Fig. 12 is an end view of a shield with a stud secured upon the same and the opposite ends of a strap buttoned upon such stud. I

a designates the flange of the shield, and b the convex portion to protect the wound.

In Figs. 1 to 4: an aluminium fastener with two tongues o and a flat head d,.1ike aMcGill paper-fastener, is shown inserted through the straps, with the tongues projected from the outer side. Figs. 1 to 3 show the flange of the out-er side of two straps s and the tongues of v the fasteners projected outwardly through the shield made with holes e'and'applied to the Figs. 5 to 7, inclusive, show-fasteners of U shape 'orstaple form havi'ng a tie-bar f and two arms g projected at right-angles therefrom. The two arms of. each fastener are shown embracing the strap and extended through two holes h in the flange ofthe shield and bentdown upon the surface of the flange to lock the strap thereto. The arms of the stapleshaped fastener embrace or cross a part of the strap instead of penetrating a single point, like the fastener shown in Figs. 1 and 4, and the strap is thus held more securely, and I have therefore made a special claim to the shield having straps attached by this form of fastening.

Fig. 8 shows tongues integral with the shield, which tongues can be used as a fastener when the shield is made of inherently non-corrosive metal. In this figure a single lug 'i is shown projected from the left-hand end of such a shield and adapted to bend over or under the strap to lock the strap thereto, Fig. 9 showing the strap on the under side of the shield. The flange is shown at the righthand side provided with two tongues j, punched from adjacent slots 7.: and adapted when projected at right angles from the flange to embrace the tape like the arms of the staple shown in Fig. 7 and to be bent down upon the tape, as shown in Fig. 10. WVith such tongues the shield can be applied to the outer side of the straps if the case admits of the manipulation of the lugs upon the under side of the straps next to the skin; but if not the ends of the shield may be first fitted underneath the straps and the lugs then adjusted to the straps and bent down upon the same.

Fig. 11 shows in perspective the surface S of a limb with a dotted shield over a cut indicated by dotted lines Z. The right-hand end of this figure shows an adhesive strap 5, having the McGill style of fastener inserted through the same, with the head upon the under side next the skin and the tongues projected outwardly in readiness to secure the shield thereon.

The left-hand end of Fig. 11 shows near one end of the dotted shield a stud m, adapted for insertion through the shield, and the opposite ends 8 of a tape applied over the flange of the shield, as shown in Fig. 12, and formed with slits or buttonholes t to engage the stud.

All the means above described provide a non-corrosive fastener for the shield which permits its attachment by the ordinary strips of adhesive plaster and permits the removal of the shield without loosening the plaster,

and thus avoids disturbing and irritating the wound or sore when it is necessary to expose the latter.

By my invention when the adhesive straps have been once attached the shield can be re moved and replaced by manipulating the fastener which connects the shield to the strap, and the shield is thus secured detachably by the straps already well known with the addition of the fastener, which by my invention is made wholly non-corrosive, and therefore introduces no injurious element to the device. It is obvious that the non-corrosive fasteners are adapted also for use with straps of nonadhesive tape to prevent the irritation of the wound when removing the shield.

What I claim as my invention is- 1. The combination, with a vaccination or analogous shield having holes at opposite ends for the passage of a fastener, of separate adhesive tapes having non-corrosive metallic fasteners with heads upon the adhesive sides of the tape and prongs projected outwardly through the tape, and engaged with the holes at the opposite ends of the shield, whereby the shield can be repeatedly engaged with and disengaged from the prongs without disturbing the tapes when once attached to the skin of the patient.

2. The combination,with an aluminium vaccination or analogous shield having holes at opposite ends for the passage of a fastener, of separate adhesive tapes having non-corrosive metallic fasteners with heads upon the adhesive sides of the tape and prongs projected outwardly through the tape and engaged with the holes at the opposite ends of the shield, whereby the shield can be repeatedly engaged with and disengaged from the prongs Without disturbing the tapes when once attached to the skin of the patient.

The combination, with avaccination or analogous shield, having holes near its opposite edges to receivefasteners as set forth, of a pair of straps for securing the shield in place, and aluminium fasteners of staple shape having the barf crossing a partof the strap and their arms inserted through the holes in the shield and bent upon its surface, whereby the strap is securely held, and the part of the fastener upon the adhesive side of the tapes in contact with the skin is of non-corrosive character.

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