Application'led December 16, 1921. Serial No. 522,774.-

improvements in freight car door locks and Y has for an object to provide a lock that will securely. hold and lock the door in its closed position and preventY any lateral or transverse movement as well as shifting', both of which movements are common in freight car vdoors with the form of locks now generallyv 1n use.

Another object of the present invention is to provide a freight'car door lock .that does away withthe hasps on the front of the door or on the frame of the .s car adjacent the front edge of the door and to provide a lock that ispreferably.positioned yat the lower right hand corner'of the door. i

ln the locks now generally employed, the hasp is often torn .from a door or the frame adjacent the front edge ofthe door and the wood work becomes damagedor torn out as the continued jarring and shifting of the Vdoor will tear the haspv or latch from its set position. Y

Another object of my invention 'therefore `is to provide a lock wherein vthere isyno strain whatever. on the latchor on the hasp, the strain falling on an arm that is especially provided and of sufcient size. and thickness towithstand the strain that will be placed upon it and thustightly hold the'door in its closed and locked position. Y j v Stillvanother object of the present invention is to provide a lock that. is preferably situated at the4 lower right hand vcorner of the door thus doing away with the usual hasp. at the front ofthe door and at the same time due to its position and construction will prevent the-door from being surreptitiously forced slightly upwardly and then transversely -to the Vcar without breaking the seal of the lock, which is possible `with the locks now in general use. Y Y

Still another objectofmy invention is to prov-idea lock consisting of an arm that is adapted to be swung into a cut-out portion Y or a ,pocket which fis formed in the lower sill of the door, which arm is of great over ,ai hasp to lock the door,

strength and when wthinthe-pocket will prevent any shifting of the door andi will also prevent the door from being moved transversely lofthe car.. ,Also a latch'w'ill be secured to this arm which will be placed `andthe strains thus falling on the` aforesaid arm and fsill with thepocket therein rather thang-on [the ha'p 'or latch.'

till another object lof the invention is -to providey a ylock for freight,V car doors coniprising two plates .one ofwhich is prefer# ably secured to the lo-werrighthand corrieri i of the door and on whiehplate is secured Qa conventional hasp and latch member formed in thelower portion of the vv plate pocket frame ,which yfits within a .pocket formed within the lower V,sill of ,the door. The second plate is provided `'with ard to Vwhich is4 pivotally secured an arm Y Y ina steel v a standadapted :to fit within said pocket and to lthe lower end of said arm Y A pass over the hasp above mentioned.

Still another object jof the invention-.is to provide a f reightcar `door lock which may be quickly and rapidly applied to .the freight car `doors now in v.use witheut i-n any "wgay changing the character of the door and with onlya minimum` amount? of labor, and; to provide a vlock which .maybe quickly and:

s secured a latch to door against :any transverse o r lateral niove.-v i ment asv well as longitudinal movement. l'

*With these Vand numerous other objectsyin 90 Y view my invention ...relates tocer'tain'fnew and novel arrangements-v :and comloinationfj of partsas will be hereinafter scribed and pointed vout intheclaims.

jReferri-ngnowto thedrawings: .Y

however, being ,opened -or in its ;u'nfast ened position. Y .y Egl S asimila-r.view,-the-1ock' in this instance, however, 4being -in .its fastened or locked position.

i, on line 7 7 of Fig. 4, the dotted lines showin the arm in several positions.

Fig-8 is a perspective of the upper plate of the lock, before'the hasp has been applied. v y

In the drawings, a portion 1 of a freight car is shown having the usual roller track 2 on which are shown the hangers 8 which support the door 4, while at the bottom of the door are shown the conventional guide brackets 5. All of the parts above enumerated are of conventional design and it will be understood that my lock, shortly to be described, may be attached to any freight car door or in fact to any sliding door.

In Fig. 1 the ordinary locking means and hasp have been removed from the door and a small strip 6 is shown fastened over the place where the former latchv was situated.

It is to be understood that my lock may be quickly and readily fastened to the doors now in use with but little effort, necessitating the cutting of only one pocket in the lower corner of the door, or the lock may be applied to the new doors when the car is constructed.

' Referring now more in detail to my invention and the enlarged views, Figs. 2, 8, 4 and 8 there is shown a plate 7 that is secured to the lower right hand corner of the door, this plate having a fla-nge side'member 8 which may be'serewed or otherwise fastened to the edge of the door, the plate is also fastened at itsupper left hand corner by a'screw or rivet 9.` This plate 7 is also slightly offset throughout its length at 10 so that a strip of ymetal 11 may be placed beneath the offset portion 12 which strip 11 is bent about midwayr of its length to formv the pocket walls 13, and then extends parallel with the plate 7 and thenis flanged as at 14 to lit snugly around the edge of the door and to be fastened to the door on its inner side.

The offset portion 12 of the plate 7 is also cut as at 15,'the edges bent downwardly to lie along the side walls 18 of the pocket.

Before applying this plate 7 and its component strip 11, a pocket 17 is cut into the lower edge ofthe door so that the pocket walls k3 may snugly fit therein. After this plate has been fastened, rivets or bolts 18 will be passed throughV the strip 11 and through the plate 7 to securely lfasten these two parts tothe door. 1 y

Angularly secured by rivets to this plate 7 is a hasp and bolt member 19 which is a conlventional one, it being positioned however',

angularly rather than vertical as in most instances.

Referring now to the other member of the lock, that is, that part which is -fastened tothe frame of the ear below the door, it will be seen that this likewiseconsists of'a plate or strip 2O (see F ig. 5) which is flanged at one end as at 2l which flange is driven into the wood, or the wood is first cut out for the reception of this end; this plate being secured by the numerous bolts 22 which pass entirely through the framework of the car. A strong upright or standard 23 is shown which is preferably formed integral with the plate 20 and extends downwardly for some distance below the plate, and to which standard is pivotally secured the relatively thick arin 24, this arm being designed to snugly lit within the reinforced pocket 17. 'lhis arm lies fiat against the upright when in its uppermost position, the upright being nearly as long as the arm, thus a supporting wall for the arm to hold it against lateral movenient in the rearward direction.

` At the lower end of this arm, that is when the arm is in a position as shown in Fig. 3, there is placed an eye 25 which has been previously passed through the latch 26,

this eye 25 being pressed or welded in the arm 24. The latch 26 is provided with a small cnt out portion 27 which is passed over the hasp on the member 19 when the arm 24 has been swung upwardly into the reinforced pocketv 17. One of the guidebrackets 5, heretofore mentioned, is riveted over the far end of the plate 2O which is clearly shown in the several figures.

After the latch member 26 has been passedl over the hasp, the conventional locking bolt 28 on the hasp member 19 will be passed through the hasp and the conventional seal 29 passed through the slot 30 in the locking bolt 28.

The operation of the lock is extremely simpleand a short description only is necessary.

To lock the door, the door will be simplyv moved to its closed position asV shown in Fig. 3, the arm 24 then'registering with the pocket will be swung upwardly into the pocket 17, it abutting against the metal edges 16 and the rear wall of the pocket 13 formed in the plate 11, and the latch then placed over the hasp of the member 19 and the bolt 28 shot into place.

' Of course, in unlocking the door, the operation is simply reversed when the door may be swung to its open position.

The many advantages of a lock of this kind will be readily apparent, the chief of which is that the arm 24 fitting snugly within the pocket prevents any longitudinal shifting of the door, and the strain, of course, falling on the relatively thick arm 24 Y pocket; these aereas@ and on the metal parts of the reinforced parts being especially designt-'d to withstand the strains and therefore not likely to be broken yor torn from their position which is so often the case with the locks now inuse.

' Furthermore not only is the door heldfrom longitudinally shifting but by swingingthe arm into its pocket andthen placing the latch'over the hasp the door `is held against any lateral movement. Y v l' Of course the bracket guides are'designed to hold the door against lateral movement,

but it is well known that robbers or people unauthorized to open the doors will someengaged from the guide brackets and even` were this possible, it could not swing later- Y ally enough to give admission to the car.-

From the foregoing it will be seen that I have provided a lock wherein all ofthe strain falls on an arm that is especially provided for this purpose and wherein none of tlie strain is placed on the latch or hasp, so that although I use a `hasp and latch member I do not subject them tothe strain that usually falls upon them. Y

Furthermore I have provided a lock tha is extremely strong and is to be placed preferably, down in the right hand lowercorner which will prevent the. door from being moved laterally by unauthorized persons and prevent unauthorized entrance to the car: and furthermore, the lock will hold the door steadily in position and prevent it from shifting longitudinally or laterally while the car is in motion` Y v Also I have provided a lock that maybe quickly applied to the doors now in use with but little effort and little expense or may be readily applied to cars under construction.

Many slight changes may be made in the plates or arms and latch members without departing in 'any way from the spirit and scope of my invention.
