CAR-SEAL.

SPECIFICATION forming part of Letters Patent No. 560,176, dated May 142, 1896.

Application filed May 13,1895. `Serial No. 549,164. (No model.)

To all whom it uta/y concern:

Be it known that we, JOHN H. SWADLING and HARRY H. KELLEY, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Oar- Seals, of which the following is a specification.

Our invention relates to car-seals, and the object of the same is to provide a seal which cannot be opened without breaking the seal.

To this end our invention consists in the combination, with a light wire to be passed through the parts used for securing the cardoor and having hook ends, of a seal or block having intersecting openings adapted to receive the looped ends'of the wire, said openings permitting one end of the wire to pass beneath the other, whereby when the ends are drawn out the loop at one end will interlock with a section of the opposite end.

Our invention consists generally in various details of construction and combination, all as hereinafter described, and particularly pointed out in the claim.

Figure 1 is a perspective view of a section D of a car door and side, showing a seal embodying our invention applied thereto. Fig. 2 is a perspective view of the wire, showing the ends of the hooks together. Fig. 3 is an end view of the seal complete. Fig. 4 is a plan view of thesame with the upper part of the wire loop cut away. Fig. 5 is a vertical sec tion on the line a; o; of Fig. 4.

As shown in the drawings, 2 represents the car-door, and 3 the side of the car, on which are the hasp 4 and the staple 5, which parts are intended to be secured together by the small seal. The seal comprises the wire 6 and the block or seal proper, 7. The block, as shown in Figs. a and 5, is provided with recesses or holes 8 and 9 to receive the two ends of the wire. These recesses or holes are elongated in crosssection and the recesses intersect one another within the block and are also at right angles with respect to elongation of the holes, as above spoken of. The two ends of the wire are hooked and the hooks bent to be at right angles to one another and brought together. r1he hook 10, which is adapted to be inserted in the slot Q, is simple in form. The other end of the wire is bent at the point 11 to cross the slot or opening and so close the same at the top, while the lower end is provided with a hook 12, having an outwardlyturned point 13, adapted to catch behind the shoulder 14, formed at the intersection of the two holes, which are preferably enlarged somewhat beneath the shoulder to permit the point 13 to project outwardly, as shown. Further, just above the hook 12 the wire is provided with a slight crimp 15, and to permit it to be inserted in the slot or openin g S an additional groove 16 is provided at the side and upper edge of the recess. the dott-ed lines in Fig. 3, the inner part of the hole or recess 9 is enlarged to permit the hook 10, when it is inserted, to pass beneath the crimp 15, when, by the inclination of the wall of the opening, the hook is pressed upwardly, so that its point will pass above the crimp and be locked by engagement with the other end of the wire, which forms a small cross-bar directly across the opening 9.

In practice the hook 12 is forced into the position shown, while the other hook or end of the wire is left free to be inserted through the hasp or staple on a car before it is inserted and secured in the block or seal proper. Thus it will be seen that the hook 12 serves simply as a fastening for that end of the wire, the part 11 serving to close the opening 8 and prevent the hook 12 from being tampered with, while that part of the wire with the crimp 15 at the intersecting points of the two openings serves as a bar or pin, on which the smaller hook fastens itself on being forced into the hole. lVhen the two ends of the wire are thus secured within the box, neither one may be removed without breaking the block or seal, which is always of fragile material and preferably of glass, so that any alteration in the form or shape of the parts within the block could be instantly noticed by one looking at the seal while on the car.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- The combination, with a block of fragile material provided with intersecting recesses or openings, of a wire loop provided at its opposite ends with the hooks 10 and 12, substantially at right angles to one another, and adapted to be inserted within said intersect- As shown by IOO ing openings, said hook l2 having its point in said hook l0 Will interlock with said crimp, 1o engagement with Jshe shoulder formed by said substantially as described.
