THOMAS EUBANK,

OF LITTLE ROOK, ARKANSAS, ASSIGNOR TO THE EUBANK CAR DOOR COMPANY, OF SAME PLACE.

CAR-DOOR FASTENER.

SPECIFICATION forming part of Letters Patent No. 512,467, dated January 9, 1894.

Application filed May 20, 1893.

To all whom it may concern.-

Be it known that I, THOMAS EUBANK, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented a new and useful Car-Door Guide, of which the following is a specification.

My invention relates to improvements in freight cars, and has special-reference to the guides employed for retaining the lower edges of the door.A

It is well known that great loss is sustained continually by reason of theimperfect fastenings of car doors and that unauthorized persons by removing the nuts and bolts of the ordinary L-shaped guide that is universally employed may pry or spring one corner of the door a sufficient distance from the openin g to give access thereto, and this may be accomplished without the breaking of the seal or otherwise giving evidence of the tampering by any external appearance of the car so that the loss is not discovered until the car has arrived at its destination and aninventory of its contents taken.

The objects of my invention are to so construct the guides for the door that even though the bolts are removed yet it is impossible to remove the guide and open the door without a rupture'of the seal.

With these and other objects in view the invention consists in certain features of construction hereinafter speciiied and particularly pointed out in the claims.

Referring to the drawingsz-Figure 1 is a perspective view of a portion of a car and door', the same being provided with a guide constructed in accordance with my invention. Fig. 2 is a vertical transverse section through the guide and wall of the car. Fig. 3 is a horizontal section. Fig. 4 is a detail end view of the guide. Fig. 5 is a vertical sectional view of the locking pin, its supporting bolt, and the door.

Like numerals of reference indicate like parts in all the iigures of the drawings.

1 designates the wall of a freight car and 2 the sliding door. Near the corner of the door a bolt 3 is located, and the same passes through an elongated slot 4 formed in the upper por- Serial No. 474.933- (No model.)

tion of a locking pin 5. The locking pin 5 is made heavy and its upper end is provided with a heinispherical head 6, while its lower end isfgiven the usual point 7.

In preparing the wall of the car for the reA ception of the guide I form the bolt holes 8,

which extend through the wall and between and slightly above the same form a cylindrical socket 9, which extends some distance into the wall. The socket is at diametrically opposite sides provided with longitudinal recesses or guides 10, the same in this instance being in vertical alignment.

11 designates the usual L-shaped guide which is of the ordinary construction with the exception that at its rear side and between its bolt-holes 12 it has formed thereupon a rearwardly disposed cylindrical stud 13 of a 'diameter agreeing with that of the socket 9. This stud is provided at diametrically opposite points and at its rear end with inclined binding shoulders 14, the same being disposed in opposite directions and in a horizontal plane. The guide is further provided in its horizontal portion with the perforations 11', for the reception of the pin hereinafter de scribed.

In applying the guide the same is turned at a right angle to its normal position when in use so that the binding shoulders 14 will take into the grooves or ways 10 with which the said socket is provided. The guide is then pushed backward and when its flange is against the surface of 'the wall of the car is given a quarter turn, its inclined or binding shoulders 14C cutting their way into the ber of the wood. By reason of their inclination the shoulders will serve to draw the guide snugly against the wall of the car where it is firmly held and it cannot be drawn out without rst rotating the guide so as to again bring the shoulders into the grooves or ways 10. After having been applied ordinary bolts 15 are passed through the-openings 12 of the bracket and the openings 8 of the car, andas usual are nutted on the inner sides. The door having been slid forward to a closed position, the pin dropped into the guide, and the door having been sealed in the usual manner it vwill be seen that even though the IOO bolts be Withdrawn it is impossible to turn the guide sufficiently to permit of its withdrawal from the socket and the door must first be slid back a suicient distance to permit this, during which operation the seal of course will be broken or fractured, and hence the tampering will be patent to an observer.

In opening the door the pin is preferably reversed so that its rounded head will ride over the horizontal portion of the bracket and not interfere therewith, said pin readily assuming such position and retaining it when once turned by reason of the preponderance of Weight being at the butt end. By the use of the bolt passing through the pin I obviate the usual chain connection which is liable to become brok-en and the pin lost.

I do not limit my invention to the exact details herein shown and described but hold that I may vary the same to any degree and extent Within the knowledge of the skilled mechanic.

Having described my invention, what I claim is- 1. The combination with a freight car and its door, of a guide bracket having a stud on its rear side and provided with bolt-openings, bolts passing through the openings into the wall of the car, a socket formed in the'Wall for the reception of the stud, and shoulders formed on the stud and engaging the Wall of the socket, substantially as specified.

2. The combination with the Wall and door of a car, said Wall being provided with a cylindrical socket having upper and lower grooves, and adjacent thereto bolt holes, of the L-shaped guide having bolt holes and upon its rear side a cylindrical stud provided at diametrically opposite points with oppositely inclined shoulders, said shoulders being arranged at variance with the grooves of the socket, substantially as specified.

3. The combination with a car door and an L-shaped guide therefor having an opening in its horizontal portion, of a headed bolt ex-4 tending from the door, and a pin slotted longitudinally above the transverse center and mounted .on the bolt and having an upper rounded enlarged end, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto alixed my signature in the presence of two witnesses.

THOS. EUBANK.
