CAR-DOGR LOCK.

Application led February 17, 1921. Serial No. 445,745.

j This invention relates to door mechanism for railway cars or the like and the principal object thereof is to provide a simple and convenient means for holding such doors in closed position.

Another object is to provide an improved arrangen'ient of locking member or hook adapted to supportingly engage a portion of the door and to provide for use Wit-h a door-supporting hook an improved hook bracketA or housing, also improved means attached to the door for engagement by the hook. A still further object -is to provide a door-supporting arrangement that will be ,o't low cost and applicable to the ycar as a simple self-contained and pre-assembled unit of car construct-ion.

`With these and Vother incidental objects in view, the invention consists ot the formation, combination and arrangement of parts as will be herein described and finally claimed..

In the accompanying drawings, which show an embodiment of the invention, Figure 1 is a side elevational vie-W of the mechanism of the resent invention, along with suiicient of tiie adjacent car construction as to illustrate its cooperation therewith. In this figure certain portions of the locking mechanism are shown in section for the purpose of clarity. Figure 2 is a vertical cross sectional view taken through a portion of the car structure, substantially on the line .2-2 of Figure l, and showing the door locking device in end elevational view. Figure 3 is a plan view of the mechanism and the adjacent portion of the car, and Figure 4 ahorizontal cross sectional view taken on the line 4-1 of Figure 1. v

Referring now to these drawings, that portion of the side of the car shown is designated 1 and the floor 2. -A pair of doors 3 and 4t are provided for the car in its floor, the door 3 being shown complete in Figure 1 but the hinge portion of the door 4 being broken away. These doors are hinged to the car structure along their remote edges kas shown at 5 for the door 3. It Willbe understood that similar hinges are used for the door 4- also. The tree edges 7 and 8 of the doors'are turned toward each other. Angle irons 9 and 10 are furnished for the free edges ot' the doors. These may extend for thetull length of the doors and are supplied to stiften and support the same. The ends ot these. angles extend outwardbeyondthe sides of the car and the projecting ends cooperate with the later described locking mechanism to hold the'doors in closed positions. Brackets 11, of, triangular form, extend across and ywithin the openings of the angles 9 and l() to stili'en the ends of the in the vicinity of the locking mechanism. These brackets orbraces are riv eted to the inner 'faces of the two legs of the angle by means of the rivets l2, thereby securely bracing and tyingthe two; legs together and making a stift' construction for a locking` face.

By arranging for the supporting ledges 23 ot the latches to seat beneath the lower edges ot the outstanding legs of the angle'irons to support the door, the metal of the angle irons is presented in an advantageous manner and the doors will not spring down from the local yield of the angles. And by locallystiliening these outstanding legs near their lower edges, as for example by the brackets 11, theV anglev irons are prevented trom distorting from the concentration of loads. f

The present mechanism does not include any special apparatus for lifting the doors, it having been found satisfactory to lift them up by hand, grasping the protruding -ends of the angle irons 9 and 10. The invention has primarily to do with an effective device whereby, when the doors are raised they will latch themselves and will be held in closed position in a simple and positive manner, and also so that they may .be readily released.

To this end, a bracket 13 is riveted to the outer tace of the car side in a position adjacent to the tree edges of the tvvo doors 3 and 4: which constitute a pair. ySeveral of the regular bottoni flange rivets 14 may be utilized for the attachment of this brack et, this series of rivets being supplied normally ior securing the flange bar 15 to the rar side l. Latches or hooks 1.6 and 17 are pivo'ted to the bracket 18 at 18 and 19, these serving to hold the doors 3 and l lrespectively in closed positions. The integral bracket 13 has front and rear walls 2O and 21, the space 22 between the walls forming a pocket for the said latches. y i f The rear or inner wall 2l constitutes the base of the bracket and the 'front or outer wall 2O constitutes a guard to overlie the major portion of the hooks or latches 16 and 17, the guard extending over the upper ends and the shanks thereof as well as portions of the latching shoulders of the saine. rlhe bracket 13 being thus securely and permanently attached to the car, it becomes in ei'i'ect an extension from the car side.

ylhe doors are preferably arranged in planes approximately coincident with the plane of the bottom edge of the car side so as to utilize the edges o't the sides as hopper openings. rEhe bracket 13 is accordingly eX- tended downwardly for some distance below the side oi the car in order that the latches may be pivoted thereupon at the desired locations with respect to the plane ot 'the doors. This form oit bracket is especially adapted for useV with cars of the type illustrated in the drawings. It is also contemplated to apply the in ention to cars of other types, hence limited modilications within the scope ot the appended claims, may be necessary.

The lathes 16 and 17 have locking shoulders at their forward edges and there lit under the upright legs oi the angles 10 and 9, the lower edges ot' the said legs ont the angles thus constitutingl locking faces for and upon the doors. The engagement points between the latches and the doors fall ontside o't the pivotpoints 18 and 19, or between the pivot points ot' the latches and the door hinge points, as tor example, the engagement point Ytor lthe door 3 lies between the pivot point 18 and the hinge point 5.v This contact point also lies above the latch pivot point 18, or between thev pivot point 18 and the door itseli, when the latter is in closed position as shown. The latch 16 is in position, when swung back toward the other Vlatch 17, to enti rely7 clear the path olf' the angle iron 10 and to allow the door to drop, the angle iron being the limit of, or the tree edge oi? the door, in the vicinity o the latch. lvthen the door is li'lted shut the inclined 'lace Zet oi the latch will cause the same to be pushed clear of the door and the latch willthen tall by gravity, or it may be swung into engagement beneath the angle iron, and as the weight of the door comes upon it the tendency will be for the latch to be swung toward the angle iron, or into "further engagement with the door. This is due to the relative location of the parts. Endv walls, such as at 25, are provided for the pocket ot the casting 13 to limit the outward movement oitI the latches or hooks 16 and 17.

The pivot pins for the latches pass through the inner and outer walls of the bracket but not through the car side, so that the latches are in reality pivoted upon the bracket. llut as the bracket with its contained parts is applicable to the car as a unit, the latches are in etlect pivoted to the car body.

llt is one ot the objects of the invention to provide a device so constructed that it may be readily applied to and removed trom the .car after pre-assembling oi" the several parts within the bracket. rllo this end any convenientarrangenient of attachment of the bracket to the car may be employed. In the present embodiment the upper portion only oi the inner wall or base 21 of the bracket 13 lies against the side 1 ot the car, the outer wall 2O of the bracket, together with the upright yend walls 25 forming with the base 21, a housing to accommodate the hooks 16 and 1'? which are operably accommodated therein. The housing is open at the bottom so that the latches may be entered and these are then pivoted upon and between the base portion 21 of the casting and the outer wall 20 by means ot the pivot pins located at the pivot points 18 and 19. As before stated, these pins are in the present embodiment arranged near the lowermost edge o1c the housing, and below the lowerinost edge of the car side, although other locations might be found to be desirable in other embodiments. 'llo the endthat the device may be preassembled and applied to the car body as a single unit of construction, it is desirable, shown in the drawings, that the pivot pins should pass through the integral walls 2O and 21 but not through the side of the car, as otherwise it would be diflicult, or even impossible to lit together and assen'ible the latches, lock and bracket remote vtrom the car and then apply the complete outfit to the c; r as a separable selfcontained unit. lt is desirable trom the standpoint of strength and stillness that the pivot pins pass through both the inner and outer'v-.falls of the bracket, and in order to Aeffect economy and ease ot application it is preferable4 `that the rivets such as 14k for securing the outiit to the car body shall pass through the base 21 oi the casting only, as it is then not necessary to extend the outer wall Q0 over the full tace of the inner wall or base 2l, but it may be made of just su'llicient extent to properly house and support the hooks and torni a guard therefor.

'lhe end walls which are integral with and connect the inner wall or base 21 and the outer wall 20, entend along the forward edges oit the hooks 1G and 17 and are shaped to substantially contorni to these edges, so 'that these end walls define the 'forward limits ot the housing and also form stops for limiting the forward movement ot the hooks, or in other words serve to limit movei'nent of the hooks toward their respective doors. rlhese walls 25 are preferably extended to follow around the contour of the tops ot' the hooks, thus following angular paths whereby is provided stillness tor the bracket without excessive weight or cost, as the angular disposition ot the upper portions of the lOl) walls 25. Alsor that upon release, either ol the two latches must be moved toward the other one. In order to hold the'latches against possible disengagement with the locking faces of the doors, or in other words, in order to hold them forwardly in the housing and substantially against the end walls 25, latch lock 26 is provided, the same to be dropped into position between the latches 16 and 17V so that neither of these latches.

can be swung back without first withdraw* ing the lock 26. Vhiler it is contemplated that the latches will, as a rule, gravitate into door engaging and supporting position, it will be appreciated that they may in some instances after having been in service a long time be prevented from doing so by excessive friction between the parts, by improper adjustment o' the parts due to accidental distortion or by an accumulation of dirt, snow or. ice in thebracket. To obviate this diiiiculty and thereby insure coinplete locking rotation ofthe latches, the lower part of the slidable lock 26 is formed as a symmetrical wedge adapted to cooperate simultaneously with the upwardly projecting portions of the latches to Jforce them toward their respective door supporting positions. This loclr lits in the pocket 22 o'f the casting 13, and guides or ribs 27 are proF vided to form a way for its operation. The integralribs or walls 27 also serve to connect the spaced walls and 21 oi the bracket and, together with the walls 25, completeJ therewith the pocket tor the operable accommodation of the latches 16 and 17 and the locking block 26. As this lock fits between the latches 16 and 17 it will be seen that tendency of either latch to move out of engagement with its door will cause the opposite latch to be forced into still further engagement-with its door unless already in full engagement therewith. lWhen the lock is liitednp either latch may be swung from beneath its door with a consequent drop ping of the door. The lock has a lip 28 which may be used for driving the lock upwardly vfor disengaging the latches or, il the latches fail to rotate completely into door supporting position, it may be used for driving the lock downwardly for forcing the latches into that position.

It will be noted that the stop walls for limiting the movement of the latchesl into engagement with the doors, as well as thefpoint of engagement of the locking block 26 with the latches 16 and 17, is above the level-of' the locking shoulders 23 of the latches, the stop walls engaging the latches on the outer sides thereof, or on the sides oi2 the latches toward the respective doors and the stop block vengaging the latches on the inner-sides, or in other words, upon the sides away from their respective doors.' This arrangement provides a maximum leverage for the efi'ect of the stop wall and locking block upon thelatches, which in the present construction may be made unusually small and of relatively light weight.

The present arrangement permits the entire bracket, withthe latches and locking blockin place, to be assembled as a complete operable unit before being applied to the car and be then applied in a proper posif tion to match with the doors, irrespective of whether the latter have been carefully manufactured and applied. to the car or not'. This is of great convenience in this art, as the car builder usually prefers to avoid all exactnessin manufacture, except where absolutely necessary. It -is the plan in the practical lapplication of thisinvention that the assembled bracket outiit will be turned out in a separate shop employing labor of the necessary slzill to lit up the parts with such nicety. as may be necessary and the assembled unit will then be applied to the car by the regularworkman in a proper position to take care or' any ordinary irregularities in the construction or vapplication of the doors.

Thus vhas been described a preferred embodiment of the invention.
