UNITED STATES PATENT orio JAMES CLARK, OF BALTIMORE, MARYLAND.
SEALINGr-LOCK FOR RAILWAY-CARS.
Specification of Letters Patent No. 27,524, dated March 20, 1860.
To all whom it may concern:
Be it known that I, JAS. CLARK, of the city and county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Sealing-Locks for Railroad Cars, &c.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this Specification.
This improvement relates more particularly to that class of fastenings known as liush locks, in which the lock is fastened to the door and the latch or hasp to the door j amb orto a leaf made stationary by bolts.
It consists in providing the lock with a projecting stud, perforated with a hole, and a latch having an opening that allows the stud projecting through it, so that a sealing wire or other substitute for it may be passed through the perforation of the stud, after the latch is in its place on the lock.
The drawing represents the face of the lock with the latch or hasp in its place, and a wire and seal securing the latch.
A is the lock denominated a spring lock; B a swinging latch or hasp.
C, is a stud projecting from and attached to the face of the lock. In the latch a suitable opening is made to admit of the stud passing through it, and with the object of making a right or left hand lock, there is a second opening (a) in the latch, so as to admit of the reversal thereof.
The escutcheon (b) for covering the key hole is swung on a pivot, and is furnished with a spring to throw it in place on the withdrawal of the key: (d) is a lip attached to the escutcheon and (d) a'corresponding out of order, the latch when sealed would secure the car. It will be obvious that in dispensing with the sealing, that the lock may be used.
The stud c having its perforation above the thickness of the latch (shown in the sectional drawing) will allow the sealing wire to be passed through it, the end of which being twisted and passed through the lead seal (or plomb), secures the wire from removal and opening the latch without previous cutting of the wire. rIhe sealing of the escutcheon is an additional security to the lock, and it is conducted in the same manner.
I am aware of a patent having been granted to Thomas Haight Sept. 23d 1856 in which the arrangement of parts differs materially from that which I employ; but
Having described my improvement what I claim as my invention and desire to secure by Letters Patent as a new article of manufacture in sealing locks for rail road cars is rIhe perforated stud c rising from the lock plate as described when employed with a swing latch and wire for sealing the lock, the whole constructed as herein specified.
In testimony whereof I have signed my name before two subscribing witnesses.
JAS. CLARK.
