CAR-DOOR LOCK.

Specification of Letters Patent.

To all whom 'it may concern:

Be it. known that we, ALEXANDER M. Won'rumo'rox, ot' Duluth, and STEPHEN J. RAETZ and JOHN W. Kincrr'rnn, of Proctor, all. in the county. of St. Louis and State of Minnesota, have invented a new and useful Car-Door Look, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specificatio Our invention relates to apparatusnscd in looking and sealing the doors ofrailway box cars and the object of the invention is to provide a car door lock having improved means by which the door is locked andsealed in such manner that without breaking the seal, unlocking and opening of the door is rendered impossible.

A further object of the invention is to provide improved means for sealing the car door lock in which the seal must pass through each part of the lock and in the use of which, when the lock is sealed at all, it

must be sealed properly.

A still further ob; ect ot' the invention is to provide car door locking mechanism of improved construction and having the looking parts constructed and arranged with relation to each other so that the liability of breakage is largely overcome and prevented, and loss of the parts is rendered practically impossible.

To that end, the invention consists in a novel arrangement of the hasp, staple and locking bolts and of openings therein,

through which the sealing ribbon or wire may be passed in sealing the lock.

Figure l is a side elevation of a car door lock constructed and arranged in :ICCOFtlHTlCt with our invention; Fig. 2 is a plan view of the apparatus shown in Fig. 1; Fig. 3 is a.

'vertical section of the base portion, on 'the line III-IIIv of Fig. '1, showing the mannor in which the ribbon or wire of the seal is threaded through the staple, hasp and bolt ot' the lock, and Fig. 4 is a sectional end viewon the line lV- -l V of Fig. l.

Referring now moreparticularly to the drawings, a.l1asp, 2, is secured to the door,

3, of a railway car, -by means of the strap,

4, having a hooked end, 5. ()no end of the hook, 5, is provided with a screw threaded portion, 6, which projects through a hole in the door and is held in place by means of a nut. 7. Button-head bolts, 8, which extend through registerin holes in the strap and door, are employer to secure the stra ns in place. The hooked end, 5, of the strap is provided withoppositely extending projections or horns, 9, which prevent-contact of the hasp and the wooden door, and also provide against its becoming disengaged from the book, 5, when in parallel relation to said hasp. One end of the hasp, 2, is provided with an oblong slot, 11, in length slightly greater than the length of the projections, 9. This slot is made long in order that when the hasp is held at right m les to the strap, the said hasp may be plaeec in or removed from the hook portion, 5, of the said hasp when the hasp is not bolted in place on the door 3. The opposite end of the hasp,2, is provided with a rectangular opening, 2 tl'n'ongl'i which the boss, l3, extends when the parts, are assembled. The hasp, 2, is also provided with a flange, 14, which extends at right angles to the outer face of the hasp and which is provided with an opening, 14, through which the ribbon or 'wire,'25, of the seal extends when the lock is sealed. As shown, the flange, 14, is pro vided with a beveled support, 15.

The base portion, 17, of the lock is provided with a longitudinally extending groove, 18. and has at its lower end :1 lug, 12), over which the hasp, 2, is adapted to be titled. latch or bolt, H3, is mounted on the base portion, 17, and is adapted for vertical movement within the groove, 18-. This latchand the up er end of the base portion are retained in place by means of the staple, 11), which enters the jamb of the door. The upper end of the bolt, 16, is provided with a handle portion, 24, by which it. may be lifted as desired. The lug, 27, upon the opposite side of the bolt, it limits the up and down motion ot the said bolt. \Vhen in its lowermost position, the bolt, 16, fits snugly within a perforation, 2t, in the upstai'iding lug, 13. The upstanding flange, 14, the lug, l2, and the bolt, 16, have-trans: versely extending registering openings or slots, ll, 1?), and, 16, through which a scaling ribbon. 25, may be threaded, the ends of the ribbon being provided with the seal, 26.

Tn the use of our improved apparatus, the door is closed; the hasp, 2, is placed in position over the lug, l3, and the bolt, 16, allowed to descend until, at its downward 1 Patented Dec. 13, 1910.

' when in place;

limit, its enlarged end extends through the these openings and the seal, 26, is placed in I position on the ends of the ribbon or Wire. The door is then looked 101 and sealed until such time as the seal has been destroyed or the ribbon broken. I The advantages of our invention will be apparent to those skilled in the art. The seal must be broken bet-tore it can be removed, as there is no Way in which the seal can be Worked out and then replaced. The ribbon must be passed through an opening in each part of the lock, including the staple, bolt and hasp, and therefore cannotbe drawn up through the pin hole. The door, if sealed at all, must be sealed properly.

The apparatus is strong, simple and du rable and is not easily disarranged.

l\lodifi'cations in the eonstruotion and arrangement of the parts may be made by those skilled in the art Without departing from our invention, and therefore e do not limitourselves to the precise construction shown in the drawings.
