4 Claims.

This invention relates to improvements in door operating devices.

An object of this invention is to provide a door` operating device comprising an arm and an actuatingA lever arranged to move said door toward open and closed positions.

Another object is to providel a door operating device comprising an actuating lever constructed and arranged to serve as the hasp of a locking mechanism for the door and requiring no modiflcation of the remainder of said mechanism.

A further object is to provide a door operating device comprising an arm pivotally secured toga relatively stationary member and an actuating memberv pivotally supported on said door, the arm and the lever being Vconstructed and arranged to impart both opening and closing movements to the door.

Other objects of the invention will become clear from the following description and the drawings illustrating a preferred embodiment of the invention.

VFigure rl is a horizontal section taken on line 'I-I of Figure v5.

The preferred structural embodiment of the invention is. illustrated in connection with double doors .ordinarily employed in railway house cars, adapted for shipment of bulky lading. The invention, however, is not restricted to such doors but may be used in railway cars embodying single door -constructions. As illustrated, the door I Il constitutes the main door andthe door I I the auxiliary door. Each of these doors is preferably provided with a plurality of horizontal corrugations such as indicatedat I2 and I3, respectively. The auxiliary door l I additionally is provided with a metallic jamb or post I4, adapted .to receive a wooden nailing strip I5. The post I4 is secured rtrated are angularly related to each other. l'lhe farm 2l of the operating lever is formed adjacent its end so as tol provide `a handle 23 by which said lever may be actuated. vThe operating lever 20 is pivotally supported preferably upon the I nain door I0 :for movement about two axes substantially at right anglesfto each other. For this purpose the main door I 0 has secured thereto .e

by means of rivets 24 a fastener 2,5. VThis fas.- tener may Aadvantageously be positioned upon a horizontal corrugation I2 of the main door and be secured thereto by the rivets 24 extending through the fastener, the horizontal corrugation and a backing plate 26 lying on the inside of the corrugation. An integral boss 21 extends outwardly from said fastener and is adapted to pass through an eye `il!! formed in the end ofthe operating lever 20. A washer 29 is positioned over the end of the boss and a rivet 3|) is utilized to secure said Washer, as well as the fastenerand backing plate, to thedoor. The washer 29 prevents the operating lever from being displaced from the boss. Projecting outwardly from the fastener 25 is an abutment member 3l positioned preferably between the boss and the adjacent end of the main door. Extending inwardly from said fastener is Ya projection 32 adapted to extend through aligned openings in said door and in a reinforcing member 33 positioned in the vertical corrugation 34. It is observed that the eye portion of the operating lever through which the boss extends lies at an angle to said boss in the position of the operating lever shown in Figures 1 and 3 of the drawings. By this construction it is clear that the operating lever may not only swing about said boss in a vertical plane but may be moved outwardly in a substantially horizontal plane for a purpose which will hereinafter appear. The arm 2I of the operating lever has its inner face recessed as indicated at 35, said recess providing an abutment 36 adapted to cooperate with the abutment 3| formed on the fastener as hereinafter set forth. Additionally, the arm 2I is provided with a slot 31, one end of said slot being extended in order to provide an abutment 38.

Adapted to coact with said operating lever is an arm pivotally secured so as to swing in a substantially vertical plane upon the auxiliary door or other relatively stationary member. As illustrated the arm 40 is preferably mounted upon a boss 4| extending inwardly from an upstanding iiange 42 formed preferably as an integral portion of a lock member 43. The lock member is secured as by rivets 44 to the crest of a horizontal corrugation I3 formed in the auxiliary door Il. The lock member is provided with a plurality of spaced outwardly extending housings 45 and 46. Intermediate these housings the lock member may be formed with a lug 41. The opening provided in the housing 45 is formed with one straight wall 48 and one inclined wall 49 and the 'opening in the housing 46 is similarly formed with a straight wall 58 and an inclined wall 5|. The housings, consequently, are adapted to receive and properly retain a vertically reciprocating tapered locking pin 52. The arm 40` adjacent its free end is provided with a socket 53 in which the end of the arm 22 of the operating lever 20 is adapted to be received. It is apparent that' the socket 53 provides abutments 54 and 55 adapted for optional engagement with the arm 22 of the operating lever.

When the door |8 is in its closed position as illustrated in Figure 1 of the drawings, and it is desired to impart initial movement to said door in the opening direction thereof, the locking pin 52-will be elevated so as to free the arm 2l of the operating lever. The handle 23 is then grasped and pulled outwardly so as` to clear the housing members 45 and 46.- This outward movement of the operating lever may be accomplished because of the angular relationship between the eye on said lever and the boss on the fastener. When the lever has been moved outwardly it may then be. pulled toward the right as viewed in Figure 1, whereupon the end of the arm 22 will engage the abutment portion 55 of the arm 40. With the abutment portion 55 serving as a fulcrum the pull upon the handle 23will be transmitted to the boss 21 formed on the fastener 25 and the door will be forced toward the right. The door I0 may then be opened to the extent desired. In the final closingmovement of the door after it has been moved tosubstantially the positionV indicated in Figure 2 of the drawings, the armA 40 and the operating lever. 26 will be in thepositions shown in dot and dash lines in saidgure. The arm 40 will then be swung to the full line position and the arm 22 of the operating leverwill be engaged within the socket of said arm 40. By grasping the handle 23 on theoperating leverthe latter is then 'swung from its substantially vertical position to the horizontal position.' During this swinging movement of the lever the arm 2 2 will engage the abutment portion 54 of the arm 40 and the door will be drawn'into tightly closed position. Y

In additionv to the operation of the operating lever 20 inthe opening and closing movements of the'door, said lever serves to lock the door I0 to the auxiliary door or other stationary member. When the lever has been actuated to move 'the main-door I0 to closed position said lever has assumed a substantially horizontal position.

Said lever may then be moved in a substantially horizontal plane to position it between the housing members 45 and 46 formed on the lock member 43. In this positioning of the operating lever the lug 41 `formed on the lock member will project into the slot 31 provided in the lever. In addition thereto the abutment members 3l and 36 formed respectively on the fastener 25 and the operating lever will come into substantial engagement. The locking pin 52 may then be inserted through the housings and the locking operation completed by the insertion of a seal extending through aligned openings 55 and 56' formed adjacent the lower end of the pin 52 and the lower end of the lock member 43, respectively. In the projected or home position of the locking pin the straight side of said pin will abut the projection 38 formed adjacent the slot 31 on the operating lever.

It is observed that in the locked position of the operating lever engagement between the abutments 3| and 36 is obtained and that the clearance between the boss 21 and the eye 28 at the left of said boss isless than the clearance between the boss 21 and the eye 28 at the right of said boss. the boss and the eye on the operatinglever is significant when the action of the lever as a lock is considered. It is apparent that in locked position the locking pin 52 will seldom, because of inaccuracies of construction, completely fill the openings in the housings 45 and 46. Consequently, the position of the locking pin will be determined by the position of the projection 38 formed on the operating lever. If the door has not been fully closed and, due to movement of the car over a track and the jarring of the door incident to said movement the door is further forced toward closed position, the boss will engage the eye on the operating lever so as to move said lever in the same direction as the door. The .tapered pin will then be released from its engagement between the projection 38 on the lever and the inclined sides of the housing members and it will, consequently, through the action of gravity, move downwardly to absorb the clearance created by the movement of the hasp.v vAnytendency of the door in its-locked position to move toward open positionV will, however, not be resisted by the eye on the operating lever and the boss formed on the fastener. Such movement will, however, -be resisted by the substantially large bearing areas of the engaging abutments 3| and 36 provided, respectively, on the fastener and on the operating lever. y

It is apparent that numerous changes an modifications of the structural embodiment of the invention will be apparent to those skilled in the art. It is intendedthat all such changes and modifications be comprehended within this inventionland that it be limited only by the scope of the claims appended hereto.
