HOPPER-DOOR LUCK.

Application :tiled December, 1924. Serial No. 756,721.

The invention relates to securing* devices or locks for dump doors ofrailway cars and has particular reference to a lock for use in connection with doors of that type which` are. pivoted or hinged at opposite sides of the center line of the car sogas to be. movable to closed position transversely of the longitudinal axis of the car..

The primary object of the invention, generally stated,"is to provide a-securing means or locking device for use in connection with this type of dump door 'so constructed and arranged that the door will be held at more than one point and consequently adequately braced or reinforced to prevent sagging under heavy load conditions.

An important object of theiinvention is tol providea construction involving attachment or adjuncts which will facilitate forcing the door into closed and seat engaging position by the employment of a suitable prybar, one ofthe elements of such including a portion of the door which may advantageously consist of means acting to Vstiften and 1 brace the free end of the door.

Another object of the invention is to provide a construction of the above mentioned character in which the side of the car is formed with an opening located preferably between the door hook assemblies for the insertion of a pry-bar whereby the edge of the opening will serve as a fulcrum when the pry-bar is engaged with a portion. of the door such as a reinforcing element mounted at the free end of the door.

A further object'of the invention is to provide a door locking mechanism in which the parts may be applied to already existing cars in a simple and easy manner and without necessitating material changes or. alterations in the construction of the car or door itself. p

The invention further contemplates the provision of various structural details which will result in greatly strengthening the door `and associated parts and thereby reduce 'likelihood of derangement, breakage. or

ably consists in the construction, arrangement and combination of parts to be hereinafter more fully described and pointed out in the appended claims.l

In the drawings, wherein like reference characters designate corresponding parts throughout the several views:

- Figure l is a horizontal section through a portion of a railway car of the type mentioned, looking toward the bottom thereof and illustrating the door in its normal or closed position.

Figure 2 is a fragmentary side elevation of the ca r showing the door hooks in cooperative engagement with tlie door arms for holding the door in closed position.

Figure 3 is al sectional view taken on the line 3 3 of Figure 2,-showing the. door in closed position and clearly illustrating the fulcrum hole inthe side of the car and the reinforcing element carried by the free end ofl the door forming a convenient pry-bar receiving means.

Figurefl is a'detailnend elevation of the i `showna fragment or portion of a car of allsteel construction, only a portion of one-half or .one side of theca'r being disclosed inasmuch as such is entirely sufficient for the purpose of illustrating the invention. A car includes center sills l, side sills 2, both of the usual channel construction and -a floor 3 which is riveted to the upper horizontal flanges of the center and side sills as indicated at 4, the side and center sills thus depending below t-he general level of the floor. The side of the car is formed of the usual plates or sheets 5' riveted to thel outer faces of the side sills 2 and reinforced or stiifened by the vertically extending stakes 7 riveted to -the side sheets and side sills, as indicated at 8. The oor 3 is formed with an opening 9 for the discharge ofthe car lading, and

this opening is normally closed by a door 10 '1 and 2, as by means of angle plates 12-and 13, respectively. Extending longitudinally of the car outwardly of the center sills l are channel beams 14 located between the V.suc-1 cessive transverse bars or beams 1l and sel cured thereto as by means of angle plates 15.

The floor or floor sheet 3 is also riveted to the horizontal flange of vthe beam 14s, as shown at 16.,

The mountingr for the door l() includes a pair of hinge brackets 1,7 riveted or otherwise secured to the outer face ofthe beam 14 and having` pintle` pins 1S extending7 thei-cthrough.i` Suitably secured, as by rivets' Shown at 1t), to the undersideof the door tu is a pair of door'arms 20 formed `as angle bars. Theinner ends ol the door arms` thatris, the ends remote from the side of the car, are shown as copcd to deliiieelongated strips 21 formed into knuckles 22 engaged within vthe brackets l? and pivoted withrespect thereto by nieansof the pintles 18 above desciibed. Obviouslyr` the door -arins Could be mounted irrespective of the hinge connections though the above mentioned construction is obviously preferable inasmuch as it reduces the number of parts and provides a strong and rigid connection which door and `further includes an angularly de` will insure proper movement of the door when swung intoV open or'v closed position, as the case may be. The outer ends of the door arms are of angular formation or shape and include downwardlyvv and out Tardly. inclined portions .23 terminating in horizontal outward extensions Qtvwhicli extend beneathand project beyond the side of the ear, as clearly indicated. As stated above, the door arms are conveniently formed of angle bars -and these bars are preferably arranged with flanges extending toward E2 for co*` their horizontal each otherras indicated in Figure operationwitli means to be described.

i One of the features of the invent-ion is the provision of a reinforcing and li'iaciiii; bridge membjer 25 which is loeatedben'eatli -the free end portion of `tlie door-l0 and secured thereto as foninstanee by means of the Arivets 26. 'lhisn'iemberuQ is substantially Z-shaped and 4includes'the horizontal iange engaging against the underside of the 'ected edge4 portion 2T-conforniinglyl exi-aap;-v ing against the inclined portions 23 of the door` arms 20 and secured thereto as for instanceby the rivets 28. Owing to the fact that this member 25-bridgcs the space be@ tween the downwardly-inclined portions of' the door arms and the door, it is quite ob-` vious thatit 'will exert a very efficient brac# ing action and make the door structure rigid andstrong so lthat, all the strain will not come upon the rivets or other securing de vices 19. f

For. holdingthe door in closed. position, I provide a pair oflock assemblies designated broadly by the numeral 29 arrangedin reversed 0 1' Opposed relation andmounted Yof upon the outsideof the rcar side 5. .Each

these assemblies bracket 3Q within which is pivoted, as at 315 a hook 324-liavinel ledges 3B and Btl adapted to be engaged beneath the outer projecting end of a door arin 2u. lilaeli assembly further includes a locking cam 8l i'iirotedwith#y in the bracliet il() and eneagcablewith the liool; 32 for the purpose of'holdingjY the latter lirinly in engagement with the associated door arm and p iifvent'in r unintentional ydisplacement.` i

In doors' of this character it. is highly desirable that sonic provision be made whereby the door mayv .be pried into itsfinal closed position by means ol' a prjcbar, crow-bar or the like. :i iioii1 e |tuiiee. l provide an opening; 35 in the side sheet 5 of the cai' and a registerii'ig hole Bllinthe adjacent side sill 2. An opening' 8i inav also advantaleousliI be provided in'tlie i'eii-itorcingr member 2.7 preferably in alineiiient with the openings shown, for the purpose of limiting the opening: movement. Assuming that the car lad in e; has` been discharged subsequent to ope`ning of the door, when it desired to close and lock .tlie'doordt may be swung by hand upwardly until the extensions 24 of the dooiI` arms engage with the first ledfvfes 33 on the hooks 32. This auxiliary locliing ledge on 4 the hooks provides means wherebyA the door or doors, although disto'rtediby service, inav be easilyheld in temporary locked position.

includes a suitableV loi IUI

After this is donc, la suitable pry-bar, crowbar or other similar tool may be inserted through the holes 35, f-lt and 37 and the bar tlieirpulleddownwardly so that the lower edgeso'ttbe'holes' and ,3G ivill serve as a fulcruiii. This downward inovemciitot the, outer end of. the prvbar will natnrally'rcsiilt in forcing' thedoor 10 upwardlyr to its seat' against the. underside. of the tloor 3, l

whereupon the hooks 32 will swing or be so moved that the ledges 33 thereof may be lengaged beneath' the extensions' 2.4i1 of vthe door arms and the cams 34 swung' into engagement with the hooks for holding them against possible displacement.

1t will be readily'appreciated that the Jfulernin feature of the invention is not limited in its application to doors ofV any par ticiilar construction as the elevation of the opening formed in the side of the car may be varied so. as to enable the inner end of the prying tool to engage with any' desired portion ofthe door. Furthermore, as it has been found that the door, notwithstanding that it has become warped, can often, .without great dif'culty, be raised to a position such that the main ledge 33 of one of the pair of hooks can engage its door arm, it will be perceived-that in such cases the auxiliary ledge 33? is not called upon to aid in the closing of the door. ledge `33 of one' of the hooks vengages with its doorfa'rm in `the manner just described, it is obvious thatthe pry-bar may be used to forcilol` move theldoor'v to permit the- A hopper door provided with the door arms and reinforcing plate or bridge member, asfdescribed and provided with the pair other of t e hooksl to supportingly engage 'of hook devices, will be notonly strong and durable in service but also extremely easy and convenlent to operate, owing to the pro.-
