ELMERWEBER, or ELDON, Iowa;

BOX-CAR'-DOOR STOP AND FASTENER.

Application filed November 5, 1921. Serial No. 513,067.

To all whom it may concern:

Be it known that I, ELMER l/VEBER, a citizen of the United States, residing at Eldon, in the county of Wapello and State of Iowa,

have invented certain new and useful, Im'

provements in Box-Oar-Door Stops and Fasteners, of which the following is a speclfication.

This invention relates to railroad rolling stock and more particularly to a novel lockmg and sealing means for the doors of freight cars and the like for preventing the accidental opening thereof due to vibration when the cars are in motion, thereby preventing loss and damage of the articles 111 transit. I

A great deal of shock is sustained by the ordinary hasp and staple used for holding the car door closed when the car is in motion, which often results in the loosening or breaking of the hasp or staple and which allows opening movement of the car doors; This is caused by the shaking back and forth of the door when the car is in motion.

' Further, after a certain length of time, the

stirrup guides, atthe heel portion of the car door become loose allowing that portion of the door to be swung outwardly a sufficient relieving all strain from the ordinary hasp and staple, and connecting seal, said means also permitting a seal to be associated therewith so that the actuation thereof by unauthorized persons will be prevented.

A further object of the invention is the provision of a novel locking device positioned adjacent to the heel ofa sliding car door, so as to preventesliding movement of the door and lateral movement thereof in relation to the car body.

A still further object of the inventioir is to provide a device of this character, which will permit the door to be held open a short space, so as to allow the free entrance of air into the car for ventilationpurposes, the said-means still preventing the sliding movement of the car door in either direction.

when the door 7 is held in its partly opened position;

A still further, object of the'invention is to provide'an improved lock and'stop for sliding doors of freight cars and the like,

which is of simple and durable construction, one that can be readily and easily applied to existing freight cars, aswell as those in the course of manufacture, and one'wliich' can be placed upon the market at a reason able cost. v

lVith these and other arrangement and formation of parts,-aswill be hereinafter more specifically described,

claimed and illustrated in the accompanying drawings, forming'a part of this specification, in which drawings:

7 objects in view, the, invention consists in the novel construction,

Figure 1 is a fragmentary side elevation of a freight car with the novelstop and lock associated therewith. V, Y t Figure 2 is an enlargedperspective view of the improved lock and-stop showing the same applied to a car and car door, and illustrating one of the locking, members or bolts being swung inposition for engaging the locking bar, and i Figure 3 is a horizontal longitudinal sec tion through a portion of a freight car anddoor, showing the improved lockand stop applied thereto, the stop and lock being 'shownin its inoperative position to permit s free sliding movement of the door in relation to the carbody.

Referring to the drawings in detail,

wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the 1mproved stop .andfastener for a door -B of a freight car C.

Thedoor B and the car C, are, of course,

-of the ordinary construction, and formv no part of the present invention, but havesim v ply been shown in order to illustrate the use of the improved stop and fastener.

The door B is slidably mounted in relation to the door opening 5 of the door C by means of an upper, longitudinally extending supporting track 6. This suspension means C is also of the ordinary or any preferred 7 type. Thelower edge of the door may be guided and held in place by the usual stir rups 7. vThe forward edge of the door Bis I held in its closed position by suitableswing- 1 ing hasp 7, which is adapted to. engagethe staple 8. In order to prevent unauthorized movement of the hasp 7 from ofi of'ethe staple 8, a seal 9-is utilized The hasp 7, the

staple 8, and the seal 9 are of the usual construction.

The improved stop and locking device A A is preferably located adjacent to the heel portion of the car door C, so that the swinging outwardly of the car door 0 on the track 6 when the guide stirrup irons 7 become loose or broken is obviated.

The improved stop and fastener A consists of a longitudinally extending rigid locking bar 10, which is secured adjacent to the lower edge of the door C. The rigid bar 10 has one end thereof extended beyond the rear or trailing end of the door C and the upper surface of this extended portion of the rigid locking bar 10 is provided with the locking bolt receiving notch 11. The eX- tended portion of the bar 10 having the notch 11 therein is designated by the numeral 12 and its upper surface is provided with a pin receiving opening 13, the purpose of which will be hereinafter more fully described.

A pair of spaced locking bolts or

latch bars

14 and 15 are adapted to engage in the notch 11, and each one of these latch bars or locking bolts 1% and 15 isprovided with an inwardly extending locking notch 16. These bolts or latches 1e and 15 are held in their spaced relation by means of a spacing block 17 and the latches or looking

bolts

14 and 15 are pivotally secured at their lower ends to the spacing block 17 and to suitable angle brackets 18by means of suit able bolts or pins 19. Theaboltsor latches 14: and 15 are held in their raised position against swinging movement by a T-shapedlatch 20 which is pivoted intermediate its ends as at 21" to the spacing block 17, in such a manner that the arms will overlie the outer surface of the latching bars or

latches

14 and 15. Itcan'be seen that when it is desired to swing either one of the

latches orlocking bolts

14 or 15 intoengagement with the locking bar 10, that it is merely necessary to operate the latch 20, so as to move the same out of the path of the locking bolt or latch which is to be swung into engagement with the locking bar 10. This permits the locking bolt or latch to be moved into engagement with the locking bar and fit in the notch 11. lVhen one of the locking bolts or

latches

14 and 15 is swung into engagement with the walls of the notch 11, it will be seen that the sliding movement of the door C forwardly or rearwardly will be absolutely precluded and that the end walls defined by the notch 16 will also prevent lateral movement of the door toward or away from the body portion of the car.

It is obvious that the door will be held stationary against all movement irrespective of the swinging movement; ofthe car.

In the drawings, the improved locking de- 1 vice and stop has been shown applied to a freight car constructed wholly of steel, but it is obvious that the same can be readily used in connection with wooden cars and in this instance the locking bolts may be fitted in a suitable pocket or notch formed in the outer wall of the car.

When one of the locking bolts or latches 1 1 or 15 is swung into locking engagement with the lock bar 11, accidental swinging movement thereof is prevented by a hasp 25, which is pivotally connected at its inner end to the latch bar 10 by means of a suitable pivot pin 21. This hasp 25 is adapted to swing over the upper surface of either one of the

locking'bolts

14 or 15 according to which one is in use, and the end of this hasp is provided with an opening 26, which is adapted to be swung into alignment with the open ing'13 or 13. A pin 27 is adapted to hold the hasp 25 in its operative or inoperative position by inserting the pin through the opening 26 of the hasp and the

corresponding opening

13 or 13 of the locking bar which is in alignment with said opening 26. The lower end of this pin 27 may be provided with a diametrically extending opening, whereby a seal 28 may be associated therewith. Thus the removal of this pin 27 and the consequent operation of the locking bolts or latches 1e and 15 will be prevented unless the seal is broken.

V-Jhen the door B is in its closed position, the notch 11 will be in alignment with the inner locking belt or latch 14:, and thusthis bolt is swung into engagement with the walls of the notch and the door will positively be held against movement.

lVhen it is desired to leave the door open a small space so as to permit the entrance of air into the same when the cars are being used for transporting cattle or the like, the

door B is moved back to position the notch- 11 in alignment with the rearmost locking bolt which is'then' swung into position with the wallsof the notch. Thus, when this latch 0r locking bolt 15 is swung into its accidental opening thereof due to vibration of the car will be absolutely precluded.

Changes in details may be made without departing from the spirit or scope of this invention; but,
