To whom vtt may concern.-

Be it known that I, BENJAMINBRIscoaot' Detroit, in the county of Wayne and State-of Michigan, have invented a new and useful Hinged Seal-Lock for RailwayfGar'Doors and I do declarethat the following is a true and accurate description thereof',` reference being had to the accompanying drawing -and to'the :letters of reference?- marked thereon and being a partA 'ofthis specifica-A tion, in which-` Eigure l sealed and Figure 2 is a similar view of thesam'e open and I unsealed.

Like letters indicate like parts in each 'gnl-e; l The nature of this invention relates to an improved-,i

method of ylocking the doors of railWay'eight-cars,

and of sealing the same when locked, so that, whenso sealed, the car cannot be entered byunauthoi'ized peisons without detection. The invention consists in the peculiarv construction and arrangement of two semicircular segmentsof unequal diameters hinged together, the larger being provided with a a'ttened extension to 'pass through a slot in a vlug at the adjacent end of the other, andper" `forated to receive .one or more leaden rivets when closed afterlpassing through the staple-bolt of the door, said rivets being headed by any convenient de-r vice and impressed with any desired seal or Cypher.

In the drawing- A represents a cast or malleable nieta] semieircular segment, having a lug, A', projecting outwardly from one end. 'The lug is slotted inthe direction: of the circumference of the segment.

'B is a similar but larger segment, hinged to the vother at d, and provided-at its other end with aflattened extension, B', which passes through the slot re- Yferred to.

The extension is perforated with several. openings,
