Description

the lever may assume a pendant position under the influence of gravity, as clearly shown in dotted lines in Figure l.

The bracket A is in the form of a plate applied to the ydoor stop 13 and the adj acenl portion of the side wall of the car, being se cured thereto by bolts 2li-2l or any other suitable fastening devices. Thatportion of the plate applied to the door stop is outwardly offset with reference to the main body portion of the plate as indicated at 22 in Figure 2 andis set into the stop so as to have the outer surface thereof flush with the outer face of the stop. Along its lo-wer edge the plate is provided with an outstanding horizontally cisposed flange 23 extending from the offset portion to the opposite end of the plate, the front end of the flange being substantially in alinement with the outer face of the door stop and door. The offset portion 22 of the plate is indented to provide a pocket as indicated at 24 adapted to accommodate the fulcrum member of the lever D# The door stop 13 is correspondingly recessed to receive the indented portion of the plate. At the bottom of the pocket 24 an outstanding lug 25 is provided having an upwardly inclined front face 26 on which the fulcrum member l5 of the lever is adapted to ride. At its rear side, the lug has a vertically disposed abutment face behind which the fulcrum member is adapted to engage. The pocket 24 is also provided with a vertically disposed end wall 27 adapted to form an abutment for the fulcrum member. As shown, the lug is spaced from the end wall 27 a suiiicient distance to accommodate the fulcrum member therebetween. Formed integral with the plate is a hood, comprising a longitudinally extending, vertically disposed side wall 28 and a longitudinally extending top wall 29. The side wall 28 is spaced outwardly fiom the outer edge of the flange 23 and t-he outer face of the door stop 13 a sufficient distance to permit the lever D to swing therebetween and a portion thereof is offset as shown in Figure 2 to accommo date the link C. The lower edge of the wall is preferably beveled'at the inner side as indicated at 30 to aid in properly guiding the lever behind the wall. Formed integral with the bottom edge of the wall .28 at the rear end of the hood is a laterally project-ing, horizontally disposed ear 3l provided with an opening for a purpose hereinafter described. Adjacent the rear end of the hood, the top wall 29 is provided with an opening 32 adapted to receive the lug 17 in one of the positions of the lever D. l

The latch member E comprises a vertically disposed bearing member 33 and a horizontally disposed arm 34 extending therefrom. The bearing member 33 is disposed between the upper wall 29 of the hood and the flange 23 having its lower end supported by the lattei'. The bearing member 33 is pivotally mounted to swing about a vertical axis on a bolt 35 extending therethrough, through the wall 29 and flange 23. The upper portion of the bearing` member 33 is of cylindrical form and bears on the curved surface 36 of the wall of a downwardly opening pocket 37 into which it extends. rl`he arm 34 is adapted to be swung into position at right angles to the side wall of the car and under the ear 3l to support the lever D when in horizontal position, as clearly shown in Figures 2 and 4. The fiee end of the arm is provided with an opening 38 which is adapted to register with the opening in the ear 3l when the arm is swung into position under the ear. The registering openings in the .arm and ear are adapted to receive the usual car seal or any other locking member in a well known manner. A vertically disposed rib 39 outstanding from the plate of the bracket A acts as a limiting stop for the arm to assure registration of the seal receiving openings.

As clearly shown in t-he drawings, when the arm 34 is in the position just described,

support-ing the lever 'D,fthe latter is confined within the hood of the bracket A and retained in'position by the walls 28 and 29 thereof, the offset portion of the plate and the wall of the pocket 36. It will be evident that the fulcrum member l5 is thus prevented from being disengaged from behind the lug 25.

The car door is cut away at the outer side adjacent the front edge as indicated at 40 to ffl accommodate the fulcrum member 15 when the lever and link are in the pendant position, and the wear plate G which is applied to the outer surface of the door and secured thereto by screws is provided with a similar opening registering with the opening in the door,the edges of the plate along the opening therein providing wear surfaces protecting the walls of the opening 40.

The supporting member F is pivotally mounted on the outer side of the door by a bolt 4l extending through the upper end thereof and is provided with a socket 42 adapted to receive the extremity of the handle 14 of the lever to support the lever in an inclined position with the fulcrum member l5 thereof so disposed that it will engage the inclined face 26 of the lug 25 when the door is moved toward the stop. The position of the bolt 4l is such that the center of gravity of the support F is disposed to one side of the pivot point thereof when the end of the lever is engaged within the socket 42 so that the support will be held in engaging position with the lever under the influence of gravity.

Assuming that the parts are in the full line position shown in Figure l, the lever being disposed horizontally with the fulcrum member thereof between the lug 25 and the abutment Wall 27, When it is desired to open the door, the follox'viiig sequence of operations are performed. The lead seal being first broken and removed, the latch member E is swung to the right, as seen in Figure l, througlranarc of 900, thereby freeing the lever D from within the pocket defined by the hood. rlhe lever is then swung ydownwardly in a contra-clockwise direction turning on its fulcrum member 15 Which at vthis time bears on the Wall 27 and the bottom Wall ofthe pocket 24, forcing the door open through the medium of the connecting link C, the lever and the link acting inthe manner of a toggle mechanism. The swinging movement ofthe lever in the described'direction is continued until the desired amount of door opening is obtained, whereupon the fulcrum ofi` the lever is manually disengaged from behind the lug 25 and the lever and link permitted yto drop to the dotted line position `shown in Figure l.

lVhenit is desi-red to close the door, the latter is moved toa position as near the stop 13 as can beconveniently `done by the operator Without the use fof tools.` Such a position is indicated in full/lines in .Figure 3. During thetime that thedoor is moved to this position, theleverD may be ysupported by the membenFJasshowm tolproperly guide the fulcrum memher of the lever into engagement with the iiiclined surface of the lug 25.' However, it is not necessary `that the leverbe so supported While pushing the door to the `position shown in Figure 3, but the same maybeallowedf to hang pendant and then manually engagedr With the lug` 25 when the door has rewheely a position shown in Figure 3, Assuming that the lever is supported as shown in Figure 3, Vas thel door is pushed toward thestop, the fulcrum member 15` will ride the inclined surface 26 of the lug 25, finally passing beyondthe same and dropping behind thelugandfwill be confined between the same the Wall 27 of the pocket 24. To force the'door to closed position, the lever D is swung in a clockwise direction, the support being first disengaged'from .the handle.` It will be evidenttliat as the leveris swung to a' horizontal position Within ithe hood of the bracket A, the door will be positively pulled shut through the medium of the connecting link C, the parts, acting inthe manner of a toggle mechanism as hereinbefore pointed out. To lock the door in position, the latch Eis swunginto en ragenient with the stopv 39, thereby supportingfthe lever lD'and preventinfr disengagement of thefulcruin member l5 from betiveenthe lug 25 andthe Wall 27. The usual seal'is then applied through the alined openings of the arm 34; and ear To lock the door in the partly opened position as shown in Figure 3, the lever D and link C are raised to the dotted line position and the lug'17 of the lever engaged Within the recess 3.2 in the upper Wall of thel hoodof the bracket. The latch E theny swung into position to aline the open ing thereof with the opening of the ear and the usua-lcar seal applied. It will be evident that the arm 34 of the latch E supports the lever D Whenin the` dotted line amount of force is applied during the closing and initial openingmovenient ofthe 1 door.
