(No Mod I BURD, J1-
SEAL LOOK. No 295.976,.
Patented Apr. 1, 1884.
ATTEST: INVENTOR:
UNITED, STATES PATENT OFFICE.
.JOHN IV. BURD, JR, OF ST. LOUIS, MISSOURI.
SEAL-LCCK.
SPECIFICATION forming part of Letters Patent No. 295,976, dated April 1, 1884.
Application filed July 30,1883. (No model.)
To a ZZ whom it may concern Be it known that I, JOHN W. BURD, Jr.,
a citizen of the United States,'residing at the.
the abovementioned objects are attained in a very perfect and efficient manner. In the accompanying drawings, Figure 1 is an elevation of my improved seal-lock5 Fig. 2, a vertical section, and Fig. 3 a horizontal section.
Referring to the drawings, A represents the main casing of the lock, secured to the doorjamb of the car, andhaving a horizontal opena ing through it for the reception of the locking bar or plate B, that is secured to the car-door. This barB is recessed out to receive a hinged locking latch or bar, 0, the end of which engages the end shoulder, a, of the casing A to lock the parts together.
0 is a spring for forcing the latch-bar O down, and c is a stop-lug on said bar to limit its downward movement.
D is a lock, of any suitable construction, for lockingthe latch-car G in its down position, the purpose being to assist in preventing unauthorized opening of the main lock. The drawings show a sliding lock bar, (I, and holding-spring d, with provision for engagement of the operating-key. Any other form of lock found most suitable or convenient may be employed.
The part of the casing A in front of the lock-.bar B and lock-latch G has provision for the reception of a plate, E, resting on springs e, so as to be capable of a limited motion back from the front plate, A, of the casing, the purpose being to admit of the easy and ready insertion or'removal of the seal-card F be tween the plates A E. The seal'card is in view through an opening, a, in the front plate, A, this opening being of a smaller size than the seal-card.
e is an opening through the spring-plate E, in line with the locking-latchG, so as to permit of the introduction of a suitable instrument-such as a pencil-under said latch, to raise it out of engagement with the casing end bar, a, and permit of the lockbeing opened. It will be seen that to get to the opening e the cardseal F must be disfigured, and that such disfiguration will show very plainly to the seal-inspector.
The seal-cards F are introduced into place from the same end at which the lock-bar B enters, and after the parts are locked its withdrawal is prevented by a projecting lug, b, on lock-bar B, which, for better security, is preferably formed with an overhanging lip, b.
I11 the manufacture of my improved lock the front plate, A, will be made separate from the main body of the lock-casing, so as to permit of the insertion of the plate E and other portions of the lock into position, after which the plate A is permanently secured in place by means of rivets or other suitable means.
I am aware that prior to my invention seallocks have been made with a plate or seal of glass covering an aperture through which access is gained in order to open the lock, and
requiring the breakage of the glass before the lock can be opened, such construction being not claim such construction, broadly; but
WVhat I do claim, and desire to secure by Letters Patent, is
1. In aseal-lock, the combination, with the latching mechanism A a B b O, of spring-plate E havin o enin e seal-card F and front 7 g P b 7 7 plate, A, all constructed and arranged substantially as herein described, and for the purpose set forth.
2. In a seal-lock, the combination, with a suitable sealing device, of the casing A, abutment-shoulder a, pivoted spring-latch 0, stop lug c, and lock-bar B, recessed out to receive the spring-latch O, as described, and for the purpose set forth.
In testimony whereof, witness my hand this 25th day of April, 1883.
L. HALLOOK,
S. S. BIssELL.
