IMPROVEMENT IIN VMEJI'ALLIC SEALS.

Specification forming part of Letters Patent No. 154,639, dated September 1, 1874 application filed July 21, 1874. Y

To all whom it may concern Be it known that I, EDWARD J. Bn'ooKs,

of the city, county, and State of New York,

have invented a new and useful Improvement in Metallic Seals, of which the following isa specification My invention relates to that class oi' metallic seals which consist essentially of a wire one end of the wire bow, which end is formed with a loop or otherwise adapted to be firmly held within the lead, and passing the other end of the bow through the loop or bend Athus formed' in the fixed end of the bow, so that when the lead is lcompressed both ends may be firmly held. My improvements consist, secondly, in combining, with a bow of wire and a ball or disk of soft metal, one or more loops ofr hard metal in the form of wire or any other form adapted to produce thedesired ei'ect, said loops being east within the soft-metal ball or disk in such a manner that the ends of the bow, in passing through the perforations in the ball or disk, will pass through said wire loops, and the latter will thus be made, when the soft metal is compressed, to bear rmly-"upon the parts of the wire \bow, and eifectually prevent the separation of the latter from the lead.

In the accompanying drawings, Figure l is a perspective view of the combined wire and leadpseal with thelead ball or disk east upon one end ofthe wire. Fig. 2 is a section of the same', representing the perforation which passes through the lead ball or disk and the contained loop of the wire for the purpose ot'` receiving the free end of the bow. Fig. 3 is a section of the same in plane at right angles to that shown at Fig. 4Fig. 4 is a section thereof, showing the free end'ot' the wire bow inserted. Fig. 5 is anv elevation of thehuished seal. Fig. 6 is a section of the same. Fig. 7 is a section thereof in a plane at right angles to that shown :at Fig. 6.' Fig. S is an bow, the end ot' the bow being introduced and the soft metal compressed thereon. Fig. 12 is an elevation ofthe wire in two parts, showing the-'holding-loop separate .from the bow. Fig. 13- is a section of the same with the lead cast upon the loops in readiness for thev reception of the bow. Fig. 14 is a section of this form of seal'in its finished state.

A represents a loop of twisted wire', which, in Figs. l to 8, inclusive, is represented as formed with-a loop, a, at one end, the shape of which is niore particularly shown in Fig. 3. Upon this loop end of the bow the lead ball or disk B is east, the perforation b, which is to receive the free end'of the bow, passing through the loop. In Figs. 9 to 11, inclusive, the bow is shown with a double loop, a a, to which the lead ball B is applied in a similar manner. In Figs. v12 to 14, inclusive, the loops a a are shown as formed of a separate piece ot' wire, Aupon which the lead ball or disk B is cast with two perforations, each passing through one pair of loops. This form of the invention enables the wire bow to be' madeA without permanent connection with the lead ball or disk.

In applying the invention under either of its modifications, the free end or ends of the wire bow are passed through the perforations of theball or disk B, and ythrough the bows therein contained, so that when the lead ball or disk isompressed upon the seal by any device customarily employed for'such purpose the wire of which the 4parts a a are formed, and which is anchored firmly within the lead, will -be caused to grasp securely the parts of the bow A, while the soft metal locks the whole together. p This device will thus the possibility oi' the end or ends of the wire bow, enlarging the apertures in` the lead seal after the latter has been compressed upon them, so as to Vwork themselves loose. My plan of surrounding the perforatious oi' the be seen to preclude lead hull or disk with :t hushingjof hard metal affords at degree of perinaneney and security 'not heretofore provided in this class of seals.

rlhe lead ball or disk nifty Vhe faced or covered with a plate of sheet metall suitably engraved or marked.

The following is claimed ats new:

1. The combination of u shackle wire", A. having" it looped end, :tud :t soft-n'ietal bail or disk, B, cast upon the looped'end of the wire A, und pierced wit-h an aperture extending through the loop ofl the wire, substantially as and for the purpose set forth. l

2. The combination of a. ball or disk of soft. metal, zt' loop or loops of hztrdmetal encircling' or bushing :m orifice in the soft metal, :uid :t wireto pass through the hushed oljfice, substantialljyT its set forth.A
