OFFICE oAnmoon-Loomne nnvrcn Application filed March 14, 1923. Serial No. 624,998.

This invention relates to car door locking devices, and has for its primary object to provide simple, rugged and compact mechanism for maintaining the door in closed position and for efliciently fortifying said door and cooperating parts of the car against the strains incident to service.

A further ob'ect of the invention to provide means or enabling the door to be m readily forced to closed position.

A principal feature of the invention, generally stated, consists in combining with a swinging car door having an outstanding marginal flange, a door'supporting mechanism comprising a latch movably mounted upon the door and means mounted-on a stationary part of the car-for cooperating with said latch to maintain the door in closed position, the said latch being arrangedto 2n overlie the said flange of the door and adapted to engage the edge of said flange when the pressure of theload within the car tends to force the door open.'

A further feature of the invention consists in the combination with the side sheet ofla railway car having an edge defining a portion of a discharge opening in the car, of a swinging door adapted to close said discharge opening, and means for supporting said door in 3;) closed position, said door having a marginal flange extending-parallel with and inside of the said edge of the side sheet, and said means for supporting the door involving a latch movably mounted upon the door, and a latch engaging member mounted upon said side sheet and extendin beyond the said edge thereof and being ofiset around said edge of the side sheet so as to approach theplane of fully closed position, said bracket having means constituting a seat or fulcrum enabling a lever to be used for moving the door from partially closed position to fully closed position.

Other features of the invention, residing in particular combinations and arrangements of parts and in advantageous details of construction of the elements of the mechanism, will hereinafter ap ear and be particularly pointed out iii the c aims.

a Figure 7- is a diagrammatic view showing the'relation of a pair of hopper doors and a spreader member formaintaining the same in spaced relation.

While, as shown in the drawings, the feaforcing the door to ings disposed transversely of the car on pposite sides of the car center sill and the doors for adjacent hoppers are connected by a spreader or stiifener'beam so as to swing as one. In the drawings 1 indicates the portion of a side sheet of a car at the lower end of a hopper, and 2 is the swinging door by which the discharge opening of the hopper is closed, the said door being mounted upon the car body by means of suitable hinges 3. The side sheet 1 of the hopper, which may be inclined as shown, is preferably provided with an offset portion or flange 4 whose lower edge of the car, such offsetting of the side sheet affording a seat 5 for the swinging door. Similarly the sloping bottom sheet 6 of the hopper may likewise be formed with an offset flange 7 bounding a portion of the discharge opening, the offsetting of this portion of the bottom sheet 6 thus affording a seat 8 for the door 2 extending parallel to the axis of swinging movement of the door.

The door 2 by which the discharge opening of the hopper is closed may advantageously be provided not only with an outstanding marginal flange 9 at the edge of the-door parallel to the offset portion 4 of the side sheet 1, but also with an outstanding marginal flange 10 bordering the'lower edge of the door in parallel relation to the flange 7 at the lower end of the bottom sheet of the hopper. When the door is closed the flanges 9 and 10 thereof lie inside of the respectively corresponding flanges 4 and The doors of each pair may be connected in spaced relationby a door spreader member-11 which is rigidly secured to said doors and preferably is a flanged section, the channel iron shown being a desirable form. The spreader 11 is of somewhat less length than the width of the car body and terminates within'the limits of the doors.

Movably mounted upon each door 2 is a latch 12 which bycooperating with a bracket affixed to a stationary part of the car, serves to support the door in closed position. The latch 12 may be conveniently mounted upon the door 2 by means of a housing casting 13 having plate-like portions 14: and 15, respectively, between which said latch extends and to which it is pivotally connected by means of the rivet 16. Between the confining plates Y 14 and 15 of the housing 13 is preferably also located a revoluble locking cam 17 pivotally mounted upon a rivet 18. When this look ing' cam is driven down against the latch 12, as shown in Fig. 3, the latter isprevented from'moving to a position permitting acci- 50 "dental release of the door. As shown in the drawings, the cams 17 for each door preferably rotate in opposite directions to secure the respective latches 12 against accidentally ereciiting an unlocking movement; and it is also toibenoted that the cams are preferably defines a portion of the discharge opening arranged so that downward movement of the portions thereof adjacent the edges of the door'produces a locking rotation of the cams.

This is very advantageous in that any acci dental blow which the cams are apt to receive from outside objects tends to force them more tightly to locked position. The latches 12 when locked in position by their respective cams 17 in effect become rigid extensions of the door stiffener beam 11, thus supporting the door against sagging on its pintles, which latter are often badly worn. The housing member 13 may be conveniently secured to the door spreader 11 by means of rivets 19.

WVhere it passes beneath the lower edge of the flange 9 the latch is preferably thickened or formed with a lug or projection 20 for seating against the lower edge of said door flange 9 when the pressure of the load within the hopper tends to force the door open. The outer end of the movable latch member 12 is formed with an offset portion or projection 21 which, by interlocking with a portion of the latch engaging bracket 22 carried by the car body, serves to arrest creepage of said bracket along the latch toward the outer end of the latter, thus transferring bulging strains of the side sheets 1 to the latches 12 and thence through their pivots 16 and housings 13 to the spreader member 11. It will thus be seen that when the doors are supported in closed position and the cams have been rotated into locking engagement with the latch, the spreader and latches, which have been made rigid therewith, function as a cross-tie to prevent spreading of the hoppers.

The door supporting member carried by the car side for cooperating with the latch 12 to support the door is preferably constructed as a bracket 22 rigidly secured to the side sheet 1 by means of rivets 28. This bracket projects beyond the edge of the side sheet and beyond said edge is preferably provided with a plurality of spaced shoulders, abutments or ledges 24 and 25, respectively, either of which is adapted to engage the latch 12 to prevent an opening movement of the door. The ledge 24 is designed to cooperate with the latch to maintain the door 2 in fully closed position, while the ledge 25 coperates with the latch for supporting the door in partially closed position. The bracket 22 may advantageously be formed with a basal plate 26 which is oflset around the flange 4, as indicated at 27 and beyond the edge of the side sheet forms the shouldered projecting portion 28 for cooperating with the latch 12. The shouldered portion of the bracket 22 beyond the edge 1 of the flange of the side sheet 1 is preferably somewhat offset toward the marginal flange 9 of the door, as well shown in Fig. 2, thus decreasing the beam lengthof the latch 12 between the said flange 9 and the latch engag- 26 is preferably skewed so as to be disposed lit? at an acute angle to the portions of said plate which bear against the side sheet 1, thus enabling the portion of said plate which projects beyond the edge of the flange 4 to stand normal to the direction of length of the door spreader member 11 when the door is in closed position. The bracket 22 is preferably fash ioned with an outstanding wall or flange 29 which is upright with respect to the basal plate 26 and extends rearwardly from the latch engaging shoulder 24 to the rear end of the bracket, the portion thereof which conmeets the offset portions of said basal plate being preferably inclined or tapered in the form of a gusset, as indicated at 30. The bracket may also be provided witgmarginal strengthening ribs 31 which are a o upright to the basal flange 26 of the bracket and are enlarged adjacent the offset portion of the bracket to likewise form gussets.

its is well known to those skilled in the art, the drop bottom doors of freight cars may be easily lifted to a partly closed position, but to close them completely requires the application of much greater force. This is because the drop bottom doors of freight cars often become warped or distorted in service by reason of the heavy loads to which they are subjected. and also because the proportionate part of the weight of the door that .is borne by the hinge decreases as the door ap proaches its closed position. It is therefore desirable to afford means for readily'applying to the door sufficient force to move it to completely closed position, and the present invention provides a form of such means adapt ed for convenient and eflicient cooperation with the door supporting mechanism disclosed herein. To this end the bracket 22 is provided with an opening 32 adapted to receive a removable lever or prying bar 33 which, as shown in Figs. 2 and 5, by being fulcru'med on the bracket 22, may be employed for readily forcing the door from a. partially closed position to fully closed position. By thus forming the fulcrum eye in the fixed hook member or by forming it in that one of the locking members which is fixed to the car body independently of the swinging door, it will be appreciated that the pressure or reaction of the pry bar on the fulcrum when the lever isbeing operated to force the door from a preliminary p0- sition to final position will not interfere with or resist the normal operation of the latch. In other words when force is applied to the pry bar the pivoted latch is free at all times to drop under the influence of gravlty'into door supporting position. If, in the door closing operation, it should be impossible to cause either outer edge of the connected doors to assume fully closedposition without the aid of a mechanical advantage, the operator may first pry the door shut on one side of the car and lock the same and then subse uently pry and lock the opposite side of the oor in fully closed position. Furthermore it will be appreciated that by forming the prying eye in the fixed hook, not only is safety assured in the prying operation, but the fulcrum is located at a most convenient point, particularly when it is necessary for the operator to stand at a lower elevation than the track or cross-ties as frequently occurs at dumping trestles. Furthermore the location of the prying eye is particularly advantageous due to the proximity of the fulcrum to the edge of the door. While the inner end of the prying lever may seat against the door plate as in Figure 5 it is preferred to have it cooperate with the door spreader or beam.

Since the hook occupies the position from which it is most desirable to pry the door closed and since the rivets employed for securing the hook to the car body are of sufficient strength to afford adequate resistance for the pry bar when the door is being forced to fully closed position the necessity of a separate fulcrum member is eliminated.

Inthe modified construction illustrated in Figs. 4, 5 and '6, the pivotally mounted latch instead of being spaced from the plane of the door by the interposition of the door spreader 11, is formed as a member 12 which is-ofiset intermediate of its length so as to project around and beyond the marginal flange 9 of the door. This latch 12 is pivotally mounted upon the door by means of a rivet 34 which also passes through said door and through a housing plate 35 overlying the outer face of the latch. Between the plate 35 and the door a rotatable locking cam 17 is pivotally secured in position by means of a rivet 36 which, together with the rivet 34 forming a pivot for the latch 12 and the rivet 37 ,provides means for rigidly securing the said plate to the door. The rotatable locking cam 17 serves to lock the latch 12 in door supporting position, as heretofore described in respect to the mechanism shown in Figs. 1. 2 and 3.

The shouldered bracket 22 which is rig-- idly attached to the side sheet 1 for cooperac tion with the pivoted latch 12 is generally similar to the bracket 22 heretofore described, differing therefrom, however, in that the shouldered projecting portion 28 of the basal plate is not turned at. an acute angle to the remaining portions of said plate but retains the same slope or inclination as the side sheet of the car against which the bracket 22 is secured. Except for the differences of construction hereinbefore described the details ofv the mechanism illustrated in Figs. 4, 5 and 6 correspond in form and function to similar details of construction shown in Figs. 1, 2 and 3, and accordingly corresponding reference numerals have been applied to the modifiedform of construction.

It will be appreciated by those familiar with devices of this character that the invention may be embodied in mechanism differing in details from those illustrated in the drawings.
