PERRY BROWN, OF LOUISVILLE, KENTUCKY;

LOCK.

@PECIFCATION forming part of Letters Patent No. 335.990, dated February 9, 1886.

Application filed October 8, 1885.

To all whom it may concern:

Be it known that I, PERRY BROWN, of Louisville, in the county of Jefferson and State of Kentucky, have invented new and useful Improvements in Locks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in locks more especially adapted for freight-car doors; and it consists in the peculiar construction, arrangement, and combination of the parts, all as more fully hereinafter described and claimed.

In the accompanying drawings, which form a part of Vthis specification, Figure l is a horizontal section of a portion of a freightcar and a door provided with my improved lock. Fig. 2 is a vertical section of the same through the lock. Fig. 3 is a similar view with the door unlocked, ready to be swung open. Fig. 4 is a perspective view of the lock detached and open. Fig.' 5 is an elevation of the same with the handle of the lock closed down into its recess in the lock-case.

Referring to the drawings by letter, A represents a portion of the body of the car, pro- Bis the door, made to nt snugly between two cleats, O, fastened on the car-body at each side of the door-opening. The door has se-v cured to it the vertical battens D, forming double rabbets, to make the door weathertight when closed. Across the door, upon the inside and at about the longitudinal center thereof, is secured a wide bar, E, which conceals the bolts of the lock, (hereinafter described,) while at the bottom of the door, also upon the inside, is secured a cleat, F, designed to rest upon the sill of the car when the door is closed. Across the door, upon the outside and near the bottom, is rigidly secured an iron bar, G, the projecting ends of which, when the door is closed, rest within the hook-brackets H, projecting from the side of the car, as shown. At the top of the door are two or more chains or other suitable con nections for hanging the door upon a rod, J, and the upper edge of the door, when closed,

projects under a rail, K, which excludes the weather, and also acts as a top fastening.

L represents the lock case, secured to the door by concealedbolts, the nuts of which are upon the inside of the door, and this case is provided with a closely-fitting cover, L', and such cover should be provided with a suitable lock for securing it in itsclosed position.

Within the bar E are secured the lockingbolts M, pivotally connected to a hub or shaft, N, common to both, in such a manner that as the shaft is turned such bolts may be simultaneously advanced or projected, so as to engage with suitable bolt holes in the doorposts to secure the door in position. The outer end of this shaft N projects through the lock-case, and has hinged to it the ring-handle O, designed to be folded down into a recess, b, in the case, beneath the cover.

\Vhen the door is locked and the handle is depressed into the recess, a hook, l?, on the outer portion of the handle enters an opening, a, in the bottom of the recess b, as is clearly shown in the drawings. Before the handle is closed, however, a suitable seal, of paper or other material that can be easily perforated, should be placed in the bottom of the recess, to hide or cover up the springlatch. The handle should then be folded down, the cover closed and locked.

In practice, when it is desired to lock the door-it first having been closed-the handle of the lock is turned in such a manner as to project the bolts My and compel them to engage with the bolt-holes in the adjoining faces of the door-posts. A seal should now be placed over the springlatch in the lbottom of the recess b, the handle closed over and engaged with such spring-latch, and the cover closed and locked.

No claim is made in this application to the means of securing the door in place, as the same forms the subject-matter of an application ijled by me July 23, 1885, Serial No. 172,407.

l. In combination with a car-door, lockingbolts adapted to be simultaneously projected or retracted by a shaft common to both, such IOO shaft being provided with a folding handle, dle, and the case provided with recess b and. a spring-latch for securing the handle, and a opening a, and a. spring-latch, as and for the 1o seal Within a lock-case for covering said latch, purposes specied. substantially as described.

2. The combination, with a ear-door, of the PERRY BROWN' shaft N, bolts M, pivotally connected thereto, Witnesses: the folding handle O, hinged to said shaft, A. F. WEBB, the hook P in the outer portion of said han- THOS. L. MARTIN.
