SEAL- SPECIFICATION forming part of Letters Patent No. 389,381, dated September 11,1888.

Application filed January 95,1888. Serial No. 261.816. (Model) To all whom it may concern.-

Be it known that I, Ln RoY O. GoDwIN, of Portsmouth, in the county of Norfolk and State of Virginia, have invented a new and Improved Seal-Lock, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved door-lock specially adapted to effectively lock and seal the doors of freightcars, being very simple and durable in construction and not liable to get out of order.

The invention consists in the construction and arrangement of certain parts and details and combinations of the same, as will be fully described hereinafter, and then point-ed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, 1n which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical cross-section of a cardoor provided with the improvement shown in a locked position. Fig. 2 is a like View of the same, showing the lock open. Fig. 3 is a sectional plan view of the same on the line 00 cc of Fig. 1. Fig. 4 is a side elevation of the sliding frame, with parts in section. Fig. 5 is a sectional plan view of the same on theliney y of Fig. 4. Fig. 6 is asectional plan view of a modified form of the improvement, and Fig. 7 is a front elevation of the locking-plate of the same.

The improved door look A is provided with a casing, B, secured to the rear side of the door 0 of a freight-car. In the casing 13 is secured a pivot, D, on which is held to turn a tumbler-plate, E, adapted to abut against the inside of the door-post F,seoured to thefreightcar, so that when the tninblenplate E is in this position, as shown in Figs. 1 and 3, the door 0 cannot be opened.

The tumblerplate E is preferably in the shape of a quartersection of a circle, and is provided on one outer end with a handle, G, and is passed between the side plates, H and H of a sliding frame, H, held to slide trans versely in the casing 13. The sliding frame H is prevented from moving too far inward by abutting at its upper and lower inner edges against the stops I, secured to the top and bot tom plates of the casing B.

In the side plate H of the sliding frame H is formed an opening, J, into which projects a rearwardly-projecting log, K, formed in the said side plate H. On this lug K operates the curved edge L of a cam, L, held to turn loosely on the pivot D, secured to the casing B. The cam L is pro vided with a straight edge, L on which operates a pin, N, secured to and projecting from the tumbler-plate E. When the pin N acts against the edge L of the cam L, it passes into a groove, J, formed in the rear part of the side plate H, as shown in Figs. 2 and 5.

In the side plate H of the sliding frame H is formed a horizontal slot, 0, through which passes the pivot D when the said frame slides transversely in its casing B. In the front parts of the plates H and H of the sliding frame H are formed the vertical slots P, in

respective side plate H or H A similarlug, R, projects from the front edge, E, of the tunibler-plate E, so that when a card or label is placed in the slots 1 of the sliding frame H said ticket S can be engaged by the lugs Q and It, and thus held firmly in position, as shown in Figs. 1 and 3. The ticket S then rests against the front edge,E, of the tumblerplate E and the outer edges of the slots P of the sliding frame H.

In the front upper corners of the side plates, H and H of the sliding frame H are formed the apertures T, which register with a similar aperture, G, formed in the handle G of the tumbler-plate E, and the three apertures T T and G register with a similar aperture formed in thelug B, projecting from the front end of the casing B. On the outer end of the lug B is an additional aperture, B for sup porting a padlock.

The operation is as follows: When the cardoor 0 is closed, the tumbler-plate E is in the position shown in Fig. 2, and when the operator now desires to lock the car-door 0 he takes hold of the handle G and moves the same upward, so as to throw the tumbler-plate E inward into the position shown in Figs. 1 and 3, the tumbler-plate E turning on its pivot D. Then the handle G stands in a vertical position, and the front edge, E, of the tumbler-plate E is in line with the inner edges of the slots P of the sliding frame H, so that the each of which projects a lug. Q, formed in the operator can insert a ticket, label, or card into the said slots P. The front of the ticket then rests against the lugs Q, and its rear side against the lug R, projecting from the front edge, E, of the tumbler-plate E. The operator now presses the sliding frame H inward, so that the lugs Q and R pass into the card, ticket, or label, thus holding the latter firmly in place in the said slots 1? between the front edge, E, of the tumbler-plate E and the front edges of the slots P, as is plainly shown in Figs. 1 and 3. When the operator moves the sliding frame H inward, the lug K strikes against the curved edge L of the cam L,whereby the latter is moved downward into the position shown in Fig. 1. At the same time the apertures T in the sliding frame H register with the aperture G in the handle G and with the aperture in the lug B, secured to the easing B, so that the operator can insert a seal through the said registering apertures, and thereby the car-door is additionally sealed. It is understood that when the tumbler-plate E is in a locked position,as shown in Figs. 1 and 3, the door 0 is held in a locked position, as the said door cannot be moved in the direction of the arrow a on account of the tumbler-plate E abutting against the door-post F.

WVhen the car is to be opened by the operator, the seal above mentioned is to be removed from the registering apertures T T and G and the aperture in the lug B, and then the operator takes hold of the handle G and moves it downward, whereby the ticket S is mutilated and the tumbler-plate E swings outof contact with the door-post F, so that the car-door G can be moved in the direction of the arrow at. The outward movement of the tumbler-plate E causes its pin N to engage the edge L of the cam L, whereby the latter is swung upward into the position shown in Fig. 2, so that the frame II, by means of the lug K, is moved and held outward until the car-dooris again locked.

Instead of attaching the lock to the rear part of the car-door O, I may also secure it to the front end, as shown in Fig. 6. In this case the tumbler-plate E engages a Z-shaped plate, V, hinged to the door-stop W, and passing with one end to the inside of the door 0 when the latter is closed, as shown in the drawings. In the plate V is formed a slot, V, into which passes the tumbler-plate E, and hence the door cannot be unlocked until the plate E is moved outward, as above described. This disengages the said notch V of the plate V.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. Ina seal-lock, the combination, with acasing secured to the car-door, of a frame held to slide in the said casing and provided with slots for the reception of a ticket or card, and a tumbler-plate pivoted in the said casing and.passing through the said frame, being adapted to engage the car-doorpost,substantiallyas shown and described.

2. In a seal-lock, the combination, with acasing secured to the car-door, of a frame held to slide in the said casing and provided with slots for the reception of a ticket or card, a tumblerplate pivoted in the said casing and passing through the said frame, and a cam turning on the pivot of the said tumbler-plate and adapted to be engaged by a lug on one side plate of the said frame, substantially as shown and described.

3. In a seal-lock, the combination, with a cas' ing secured to the car-door, of a frame held to slidein the said casing and provided with slots for the reception of a ticket or'card, a tumblerplate pivoted in the said casing and passing through the said frame, a cam turning on the pivot of the said tumbler-plate, and a pinsecured to the said tumbler-plate and operating on one edge of the said cam, substantially as shown and described.

4. In a seal-lock, the combination, with a pivoted tumbler-plate having a lug on its front edge, of a frame through which said tumblerplate passes, provided with slots and lugs projecting into the said slots, so as to hold a card or ticket in place in the said slots at the front edge of the said tumbler-plate, substantially as shown and described.
