PATENT I OFFICE,

MARK D. FLOWER AND WILLIAM G. DENNEY, OF SOUTH ST. PAUL, ASSIGNORS TO THE ST. PAUL CLAY CAR SEAL COMPANY, OF ST.

CAR-SEAL.

SPECIFICATION forming part of Letters Patent No. 513,908, dated January 30, 1894.

Application filed March 2, 1893.

T0 aZZ whom it may concern:

Be it known that we, MARK D. FLOWER and WILLIAM G. DENNEY, citizens of the United States, residing at South St. Paul, in the county of Dakota, and in the State of Minnesota, have invented certain new and useful Improvements in Seals for Cars and for other Purposes; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of our seallocket and shackle separated from each other; Fig. 2, a Vertical section thereof united; and Fig. 3 a horizontal section on line 0cw, Fig. 2.

Letters of like name and kind refer to like parts in all of the figures.

The object of our invention is to provide an improved seal, for use on cars and other places Where sealing is required, and, to this end, said invention consists in-the seal, and the parts thereof constructed as hereinafter specified.

Our invention relates more especially to seals ofthe class shown in the application of William G. Denney,- Serial No. 445,170, filed September 6,1892; which comprise a metal shackle, and a locket of some hard, and. brittle, or friable material, as baked clay, pottery, &c.,the sealing being elfected, by latching the ends of the shackle to the locket, by self-act-v ing catches, while the unsealing is effected either by breaking the locket, or cutting the shackle.

In carrying our invention into practice we prefer to make the locket A of baked clay, giving it, in general, an oblong shape, with flat sides, and-having its greatest length in a horizontal direction. In this locket is a hori-' zontal chamber on extending entirely through it and having, near each outer end, an abrupt downwardly projecting shoulder a adapted to be engaged by and to hold the latch end of the shackle B. The shackle B is made'of metal wire or strip. and consists of two straight side pieces 17, b, a curved or arched piece b uniting them, and an inwardly projecting latch, of a shape to be de- 4 extending piece 19 scribed, at the free end of each side piece.

Serial No. 464.299. (No model.)

The latches stand substantially at right angles to, and lie in the same plane, as the side pieces 6, b, so that, when they are inserted into the locket, the side pieces can come squarely against the sides of the locket, and cover the opening into the chamber a. This covering of the chamber opening is to guard against the insertion of an instrument, for the purpose of disengaging the latch from the shoulder a, and also, the entrance of rain or snow. The construction thus far described differs in no essential respect from that shown in the Denney application above referred to.

In order to add to the security of the closure of the chamber, by the shackle sides, we extend the two sides and bottom of the locket outward, so that the shackle sides will be wholly within them, when the latch is locked in the chamber. The sides I) being set within or let into the ends of the locket, it is impossible for an instrument to be worked in between them, to expose and afford access to the chamber. The portion of the shackle side thus inclosed, is also situated, so that it will be impossible to cut it and then reunite the parts.

Each latch consists of an inward extension 12 of the side piece, that stands at substantially a right angle thereto, and at its innermost end curves upward and outward, and

terminates in an outwardly and upwardly The parts b and b of the latch are not straight, as is the case with the latch shown in the application hereinbefore referred to, but curved, the former being curved upward toward the other and the latter being curved downward toward the former.

By this curvature, the latch, is made more elastic, and said parts 6 and b can be pressed closer together, than where they are straight, thus enabling the employment of a much smaller opening into the chamber a for the insertion of the latch.

Having thus described our invention,what we claim is- 1. A seal locket having a chamber for the reception and locking .of a shackle latch, whose'entrance has, adjacent to it, an extension or projection from the locket to closely overlap the portion of the shackle at such enlatch entering openings, and extensions, or :5

projections on the locket adjacent to the latter to inclose portions of the side pieces of the shackle, substantially as and for the purpose described.

In testimony that we claim the foregoing we 20 have hereunto set our hands this 7th day of February, 1893.

MARK D. FLOWER. WILLIAM G. DENNEY.
