Application filed May 6,

To all lwhom t may concern l Be it known that I, EDWARD A. MAYHEW, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful lmprovements in Car-Door Fasteners, of which the following is a specification.

My invention relates to a car door `fastener and more particularly to the type of fastener employing a locking pin having a slot or` slots through Ywhich a sealing wire or metal ribbon may be placed to prevent the unauthorized opening of the car door.

ln existing fasteners of this type, the construction of the parts is such that it is possible for an unauthorized person to cut or break the seal, raise the locking pin, open the door, remove articles from the car, close the door, replace the locking pin and seal, the ends of the seal for example being bent andv sometimes Alooped around each other, andthe repaired break then slipped into the slot` in .the locking pin where it is hidden from sight.v V

The object of my invention is to provide a car door fastening device. of suoli construction as to expose toview the `portion of the wire or ribbon whichretains the lock pin or equivalent member so asto make impossible such fraudulent manipulation of the seal as has been just mentioned.

The invention consists in the novel and improved structures, arrangements and devices to 'be hereinafter described and claimed for carrying out the above said object and such other incidental objects as will appear from the following description.

The invention is illustrated in a preferred embodiment in the accompanying drawings wherein,

Figure 1 is a fragmentary front eleva tional view of a car door provided with a door fastener embodying the principles of my invention.

F ig. 2 is a sectional view taken on they line 2 2 of Fig. 1.

Figs. 8, 4, 5 and 6 are enlarged sectional views taken onj the respective lines 8 8, 4 4-, 5-5 and c6 of Fig. i.

F ig. 8 is a perspective view of the locking pin.

Specification of Letters Patent.

Patented Sept. 13, 1921.

1919. Serial No. 295,144.

Like characters of reference designate' like parts in the several figures of the drawings.

rlhe part of the car illustrated fragmentarily in the drawings is of common construction and includes adoor post 10, door stop 11 and sliding door 12. A bracket 13 is rigidly secured to the door stop 11 by means of bolts 14 and is preferably provided with the

bracing flanges

15 and 16 also bolted to the car. The bracket 13 is provided with the outwardly projecting lugs 17 and 18which are perforated for the locking pin 19. A hasp 20 having a slot 21 adapted to pass over the lug 18 is fastened to the door by means of a staple 22. My invention relates especially to the lock bracket and'locking pin construction.

rfhe locking pin 19 is substantially U- shaped in cross-section having a back web 23 and integral forwardly flanges or ribs 24, the ribs projecting outwardly at right angles from the web portion. The top of the locking pin has an integral cap piece 25, the margins of which project outwardly beyond the sides and front of the ribs 24 to form a flange to hold the locking pin in the bracket. The* lower end of the locking pin is bifurcated, the opposite ribs 24 thereof being each provided with a slot 26. The web portion 28 extends slightly below the middle of the locking pin so that when the locking pin is inserted in the openings forme in the

lugs

17 and 18, the upper edges of the slots are even with the bottom of the lug 18 and the lower edge of the web portion 23 is even with the top of the lug 18. rlhe opening 27 through lug 17 corresponds in shape to the cross section of the locking pin (F ig. 5). After the locking pin has been put in place in the bracket tie corners 28 of the forward edges of the ribs may be bent inwardly so that the distance between them is considerably less than the width of the integral web 17n of lug 17. This arrangement prevents the locking pin from being completely withdrawn from the bracket. rlhe lug 18 is provided with two openings 29-29 which are separated by a vertical web 80. Horizontal webs 31 extend partially across openings 29 substantially closing the spaces behind the ribs of the locking pin. The webs 31 are provided with forwardly projecting portions 31 which substantially close the spaces between the ribs 24 and the web 30 except at the forward corners which are left open to permit the bent in corners 28 of the ribs 211 to pass through lug 18 when the locking pin is raised to release the hasp. The lug 18 serves as a staple over which the hasp may be placed and the lug 17 serves as a guiding member to guide the locking pin into the staple. Y

The car is sealed by raising the locking pin, placing the hasp over the lug 18, inserting the locking pin through the openings in the lug 18 and then inserting the sealing wire 32 through the slots 26-726 and securing the ends together by means of a lead seal 33. The term sealing wire is used in the specification and the appended claims in a broad sense and includes a wire, metal ribbon or the like. As shown in Fig. 4f, the projecting portions of web 31 extend forwardly slightly beyond the' front. edges of the slots 26. This arrangement prevents the locking pin from being lifted after the seal has been applied because the clearances between the projections 31a and the ribs 24; of the pin are not sufficient to permit the sealing wire to pass along the pin. If, however, because of poor workmanship there is suiiicient room to pull the sealingwire up along with the locking pin the web 30 will prevent the sealing wire from being pulled through the lug 18 so that itis impossible to remove the hasp without breaking the Seal or'the sealing wire even though the pin be drawn up far enough to clear it. As shown in the drawings, the ribs 211 of the locking pin extend forwardly and since they are relatively narrow in width, the seal and substantially all of the sealing wire is exposed to view thus making it impossible to Y hide a repaired break in the sealing wire. i

While I have described my invention in a certain specific embodiment, it will be obvious that structural modications might be made without departinr from the spirit of the invention. `Il there ore do not wish to limit the invention to the exact structures shown and described except only so far as speciiic limitations may appear in the appended claims. i

I claim:

1. In a car door fastener, a bracket having a staple, a Vhasp adapted to be placed over said staple, a channel shaped locking pin adapted to be placed in said staple over said hasp, the ribs of said channel shaped locking pin projecting forwardly, each hav ing a slot so that when the pin is placed in the staple the slots will be below the staple, said slots adapted to receive a sealing wire, said bracket having a perforated lug formed thereon over said staple to guide the locking pin, said lug having an internal web projecting between the 'ribs of said pin, the lower ends of said ribs being bent inwardly atter'the pin has been inserted in said guid- Y ing lug to engage said rib and prevent the pin from being completely withdrawn from said guiding lug.

2. In a car door fastener, a bracket having a perforated projection, a hasp adapted to be placed over said projection, a locking from said projection. Y
