The operation of the device is exceedingly simple: supposing the door is .in its locked ufbe deaf-1y 5 l 'point "16 at,v its position, to unlock the same, it is first only v lnecessary to swingv the'dogY 17k rearwardly and-knocktheE hook 51frorn beneath the leg of the angle lJfan'd to lock the door,l vof course, the operation is simply reversed.

Y v From the foregoing it will be seenfthat l have provided a locking meansthazt' is V-eX-Y ceedingly simple in construction, mayV be readily and quickly applied to freight vcarsv and is` easily operated to lock the door land tightly hold the. same in its lockedposition. In the drawing, AI have ,shown only one Y Vside of a car `and vone locking'device, but it willbe understood that in numbers off instances, a similar arrangement willvbevused ffi `forming the bracket with,` integral on the opposite sides'of the carand door so' that the doorwill `be supported and locked f1omlboth of its outer` ends.

- :spacedinner and outer walls,- 1in both of '--\vhich, thefpivot' pin 13 :has bearing, it will vbe seen that the` pinll'will be held inarigid Y mannerso thatnoudue looseness of', `the hook can 4develop v1n Vservice from, relative movement .between the inner; and outern lbear-y ings f or the pivot pin. 1 Furthermore, thein- :tegral end yWallithatv unites the yinnerv and outer walls tojformthehousing is arranged Y, tov follow the linesof the forward edge of j ,.a'bove the pivot pin. ,'And it will also y*be noff,ticed that-by. diverting theconnecting wall Y soV that the housing 11V is joined to the inner thehook .whenit isin' its extreme forward i position, soj that the unsupported area ofthe outerwall A11'. is reduced tofa minimum and A alsoI a stop is provided Within the bracket f itself for thehook. The arcuate upperend lO'of the connecting wall follows aroundthe circular end of the hook. above the pivot point -thereof so that thedownwardforce fromthe n load ofk the pin V13 will beresisted in part by this joiningvmetallocated in hoodfashion in vthis manner, it follows lan angular path y wall orbase by an, upright4 connecting'wall fof. extremely lightweight *andv yet of great strength'in yall ,directiens.k ,This isV of impor-, tance asthe casting is frequently subjected :to abusesuchv as ,being struck by a hammer Y Y or agbiarl bythe workmen. Y Y 7 f Y jBy mak'ng the outer wallv 11 of less extent than the* inner wall, the rivets forfsecuring' the bracket tothe cai-*may `pass through the Y .i inner wall only, thus making them easier to f drive and of less weightjthanl werasthey y passed through a greater grip: o f `mat erial.

f' The. rivet forming the pivot pointof the ldog k:Ulisr` preferably loosely drivento avoid p clamping the dog against the faceV of the 'i bracket, hence this rivet offers but little revslstance against slippage of the bracket. The other three rivets, however, may be sec'urely driven, two of them lying to one side of the hook and along the edge of the hook.

Therivets are thus'arranged to balance the.

forces from the hook and will hold the bracket against vslippagevor rotation, while,V -at the same time-the rivets, particularlythe two important ones lying along the connecting walls of metal, pass through the bracket at points. especially able to withstand the v yconcentration of rivet pressures.

It will thusbe seen thatl inthe arrange- .ly simple construction, but at the same-time ment ,as shown/anddescribed, I havejproduceda vdoorflocking mechanism of lextremewithal-he elementssoarranged that no) metal iswasted andthe device is ofext'remely light weight.
