SEAL-LOCK.

SPECIFICATION formingpart of Letters Patents No. 287,299, dated October 23, 1883.

` Application filed October 16, 1882. (No model.)

To all whom, it'7nay concern:

Be it known that I, VIRGIL A. KREPPS, a citizen of the United States, and residing at New York, in the county and State of New York, have invented new and useful Improvements in Car-Door Looks, of which the following is a specification.

The object of my improvemcnts in car-door looks is to provide Simpler, cheaper, and more efficient locks for freight-cars than any now in use.

The said inprovements consist of a bolt attached to and projecting from the edge of the door to enter a lock-case in a aleat on the doorframe, and be there Secured self-actingly by a vertical swinging catch having hooks on its under side en gaging with corresponding hooks on the upper side of the bolt, the said catch having an arni eXtending backward from its pivot out through the opposite edge of the aleat in which the lock-case is formed, where, in the angle between said aleat and the side of the car-body, a projecting stud of the aleat is located for a means of fastening the catch by a seal or padlock, which are much less exposed in said angle to accidental injury than when located on the front of the door or aleat, or suspended below them, as in some other arrangements. The contrivance is also so designed that the padlock may be temporarily Suspended on the locking-stud and in connec tion with the door-catch to hold the latter up free of the bolt when the door is to be opened, so that the attendant may not be obliged to give any attention to it while opening the door after unfastening it, as required in some cases, thns affording the attendant the free use of both hands for sliding the door open, whereas many locks are so arranged that he must either hold the catch up with one hand while sliding the door with the other or block up the-catch with a stick or other object beforehand.

Figure 1 in the acconpanying drawings is a longitudinal sectional elevation through the lock-case, and side elevation of the bolt and part of the door, the section being taken on the line x x of Fig. 2. Fig. 2 is a side elevation of the lock as seen looking in the direction indicated by the arrow in Fig. 1. Fig. 3 is a front elevation of the lock, the catch being disconnected fronLthc bolt and the door by bolts d, or by any other approved means, to

project into the chanber e of the lock, 'formed in the aleat f, and containing the gravity-aatch h, having hooks z', to engage the bolt automatically when it cnters the lock-case, said catch being arranged on the pivot-bolt j, so as to be raised by the bevel k of the bolt, acting on the bevel Z of the catch, the catch being Suspended at'the proper level by the contact of the back m with the end n of the slot oin the inclosingplate p of the rear side of the lock-case. The arm q of the catch projects outside of the lockcase through slot 0 and alongside of a stud, s, attached to plate p, and suficiently higher than said arm to receive the hasp t of the padlock u through its hole o, above a notch, w, in the upper edge of said stud s for looking the catch. Said arm q also has a small hole, x, which is coincident with. a similar hole, y, in the stud s, when the catch is engaged with the bolt, to receive the wire z of a seal, when it is desired to use that method of security. The

notch w in the stud s also serves for the lodgment of the hasp of the padlock when used for a weight to hang on the top of arni q for holding up the catch, as shown in Fig. 3, to force the bolt preparatory to opening the door.

The cleatf, in which the chamber eis formed,

represents the piece usually attached, to the side a' of the car-body for` the connection of the lock. The said chamber is forned in it by boxing it out from side to side about half its thickness, or a little more, and closing the notch at the edges by the plates ;p and b', which are properly and respectively slotted for the bolt a and catch h. The pivot-bolt j for the catch h is also a fastening-bolt for the cleat f,

said bolt passing through the slide a'of the` IOC the side of the car-body.

of the hooks is such that the point-s i swing close to the bottom of the notches in bolt (gas shown by dotted lines g and hold the bolt withoutany slack, keeping the door close shut.

The importance of this lock will be appreciated by those whose experience in freightcar service has taught them the need of a simple lock that can be readily and cheaply applied to any cars, and can be as Conveniently manipulated as the one here represented.

It is to be understood that while I have described the bolt a as attaehed to the door and the catch b attached to the side of the carbody they may be reverscd as to their positions,' and I do not linit myself tothe arrangement as described, for I may, if preferred, j locate the catch on the door and the bolt oni Having thns described my invention, what; I claim, and desire to secure by Letters Patent,

1. The 'improved lock for freight-car doors, E consisting of book-bolt a, attached to the door, book-catch h, having a perforated arm, q, and attached to the side of the car-body and lo-` cated in the lock-chamber, and a fastening-` stud, s, exterior to the lock-chamber, substan- I tially as described.

2. 'The combnation of the perforated Stud stud having a notch, w, for the lodgment of the padlock-hasp over the arm' of the catch, for thepurpose of holding the catch out of engagement with the hasp, snbstantially as described.

5. In a lock for freight-car doors, consisting, essentially, of book-bolt a and book-catch h, the

said catch having an arm, q, and the lock having a fastening-stud, 8, -therefor, said arm and stud being located in the angle between the side a' of the car-body and the cleat f containing the lock-case, substantially as described. In witness whereof I have hereunto signed my'name in the presence of two subscribing witnesses.
