SEAL FOR BOX-CARS, &o.

Specification of Letters Patent.

To all whom it may concern Be it known that I, WILLIAM H. NORTH- ALL, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented a new and useful Seal for Box-Cars, &c., of which the following is a specification.

The invention relates to improvements in seals for box cars, beer boxes, and various receptacles.

The object of the present invention is to improve the construction of seals for box cars, beer boxes, and various other receptacles, and to provide a simple, eflicient and comparatively inexpensive self-locking seal, equipped with the relatively narrow flexible strip or shackle, which will not require a large opening, so that the same may be substituted for those having wire shackles.

A further object of the invention is to provide a seal of this character, which will have to be destroyed in order to obtain access to the car or receptacle sealed.

With these and other objects in View, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a perspective view of a seal, constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view on the line 33 of Fig. 2. Fig. 4 is a similar view on the line 4-4 of Fig. 2. Fig. 5 is a transverse sectional view on the line 5-5 of Fig. 9. Fig. 6 is a detail edge view of the casing. Fig. 7 is a detail perspective view of the flexible strip or shackle. Fig. 8 is a detail perspective View of the intermediate locking plate. Fig. 9 is a longitudinal sectional view of a car seal, showing another form of the invention. Fig. 10 is a detail perspective view of the locking plate, shown in Fig. 9. Fig. 11 is a perspective view of the flexible strip shackle, shown in Fig. 9. Fig; 12 is a detail view of one of the sections or members of the casing.

Like numerals of reference designate coran intermediate locking plate 4, arranged in spaced relation with the side walls of the casing, as clearly illustrated in Figs. 4 and 5- of the drawing. The sections or

members

2 and 3 are provided with

peripheral flanges

5 and 6, which are bent around each other to form a seam, and the locking plate, which is in the form of a disk, has its peripheral portion secured between the

peripheral flanges

5 and 6 of the sections or

members

4 and 5 of the seal casing. The casing is provided at its periphery with a transverse entrance slot 7, and the peripheral flange 5 of the section or member 2 is cut away at 8 at opposite sides of the slot 7, while the section or member 3 is provided at the cut away portions 8 withspaced lugs 9. The intermediate locking plate 4 is provided at its periphery with spaced lugs 10, corresponding with said lugs 9, and both sets of

lugs

9 and 10 are bent over against the section or memher 3, as clearly illustrated in Fig. 6 0f the drawing. By this construction, the locking plate is held against rotary movement within the cylindrical casing. The locking plate is provided with an opening, which is divided into two

separate portions

11 and 12 by a rear catch 13, extending forwardly or in the direction of an entrance channel 14. The locking plate is provided adjacent the entrance with a front catch 15, extending inwardly at one side of and constituting one of the walls of the entrance channel, and converging inwardly toward and terminating adjacent to the inner side wall of the divided opening. The front catch is tapered, and it forms a tapered entrance channel 14, as clearly shown in Figs. 2 and 8, and the inner wall of the divided opening is provided at the portion 11 with a bulge 16, located beyond the point of the front catch and adapted to direct a flexible strip or shackle 17 upon its withdrawal away from the point of the catch 15 into the second portion 12 of the opening. The side edge 18 of the front catch is straight and is located .at the entrance 14, and the other side edge Patented Sept. 17, 1912.

lateral passage 22 into 19 is convexly curved or bulged to assist in guiding the flexible strip or shackle upon its attempted withdrawal, past the lateral connect-ing passage and into the second portion 12 of the divided opening. The rear catch 13 is provided with

curved edges

20 and 21. The edge 20 is convexly curved and is located at the front portion 11 of the divided opening, and the other side edge 21 is concavely curved and is located at the second portion 12 of the divided opening. By this construction, the rear catch is hook-shaped for more effectually engaging and locking the flexible strip or shackle. The front cat-ch is interposed between the rear catch and the entrance 14, and the space between the front and rear catches constitutes a lateral passage 22, which connects the two

portions

11 and 12 of the divided opening, so that the two

portions

11 and 12 of the divided opening will successively receive the engaging terminals of the flexible strip and form a double lock for the same.

The flexible strip 17 is providedat its terminals with

slots

23 and 24. The terminal, which has the slot 23, is first engaged with the seal by introducing it into the entrance 14 and moving it inwardly until the outer wall of the slot 23 passes the point of the front catch. The flexible strip or shackle is then drawn backwardly or outwardly and is guided by the bulge 16 and the front catch 15 through the passage 22 into the second portion 12 of the divided opening. The concave bulge 19 and edge of the rear catch will prevent the end of the flexible strip or shackle from returning through the passage 22. The terminal, which has the slot 23, may be engaged with the locking plate at the time the parts are assembled, or after the locking plate'is secured between the sections or members of the casing in the manner just described. The other or free end of the flexible strip or shackle is provided at the outer 'end of the slot 24 with a. resilient tongue 25, arranged at an angle to the plane of the free end of the flexible strip or shackle, and adapted to be compressed within the slot 24 to permit the free end'of the flexible strip to pass through the entrance 14 into the first portion 11 of the divided opening. After the free end of the flexible strip is introduced into the first portion 11 of the divided opening, the tongue 25 will spring laterally so as to engage with the point of the front catch, and thereby guide or direct the free end of the flexible strip through the the second portion of the divided opening, when the free end of the flexible strip is drawn backwardly or outwardly. The outward or backward pull upon the flexible strip or shackle forces the free end into the second portion 12 of the divided opening where it is engaged by the point of the catch 13, whereby the flexible strip or shackle is doubly locked and effectually prevented from being withdrawn without destroying the seal.

In Figs. 9 to 11 inclusive of the drawing is illustrated another form of invention, in which the attached end 26 of the flexible strip or shackle 27 is provided with a lug 28, formed by recessing the attached end 26 at 29. The lug 28 is engaged with a slot 30 of the locking plate 31 before the same is secured between the sections or members of the casing 32, which is constructed similar to that heretofore'described. The recess 29 is of sufficient length to extend from the slot 30 to the entrance 33. The other or free end of the flexible strip or shackle is provided with a slot 34 to engage with front and

rear catches

35 and 36 of the locking plate 31. The locking plate 31 is provided with an opening, which is divided into two

portions

37 and 38 by the rear catch 36, and the front catch, which tapers inwardly, converges toward. one of the side walls of the divided opening to form a tapered entrance, and it is interposed between the entrance and the oint of the rear catch, and it co-acts withthe latter to form a passage for connecting the two portions of the divided opening. When the free slotted end of the flexible strip or shackle is introduced into the cas-' ing, it is moved inwardly pastthe front catch and when it is drawn outwardly, it is carried through the passage 39 into the secend portion 38 of the divided opening. The front catch has one of its side edges contiguous to the side wall of the first portion 37 of the divided opening, so that it eflectually prevents the free end of the flexible strip orshackle from being withdrawn from the casing, and it is sufliciently resilient to permit the free end of the flexible strip or shackle to be readily introduced into the clivided opening. When the free end of the flexible strip or shackle is carried into the second portion 38 of the opening, it is engaged by the rear catch and is doublylocked.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A seal of the class described including a hollow casing having an entrance at one edge, a locking plate mounted within the casing and provided with an interior opening, the walls ofthe opening projecting into the opening from opposite sides and overlapping in spaced relation to divide the opening into a front and rear portion connected by a narrow lateral passage, the locking plate having an entrance channel registering with the entrance to the casing and adapted to afford passage to a flexible strip provided in its ends with engaging openings, the entrance to the locking plate continued as a narrow inwardly tapering channelcutting into the rear portion of the opening at lea a slight angle, the wall of the said rear portion of the opening forming a continuation of the entrance wall and disposed at a slight angle thereto to direct the strip upon attempted withdrawal past the mouth of the entrance channel and through the lateral passage into the front portion of the opening, the wall of the front opening adjacent the lateral passage curved to direct the strip away from said passage to prevent its return therethrough.
