As clearly illustrated in Figure 3 of the drawings the backing member which lies within the horizontal corrugation 23 to which the hasp fastener is secured is extended so as to lie within the vertical corrugation 24. This extension of the backing member 27 is permitted because of the fact that the horizontal corrugations merge within the vertical corrugations of the door. By such extension the neck 28 of the hasp fastener is adapted to extend through aligned openings in the corrugation 24 and in the backing member 27 so that the stress applied to said neck is carried directly back through the backing member to the securing rivets 26. The extension additionally serves to reinforce the vertical corrugation 24 and because of the integral a structure between the reinforcing portion of the backing member and the remainder of said member said portions is effective to prevent tearing of the panel at the vertical corrugation and the pulling out of the end of the neck portion 28 extending into said portion.

matter of the hasp fastener as above described is not claimed herein but will be made the sub-.

ject matter of a separate application.

Pivotally supported from the neck of the hasp fastener is a hasp 29. The hasp is provided with a slot 30 and extending from said hasp adjacent one end of said slot is a vertically inclined lug 31. Attention is invited to the fact that the lug 31 is provided with a face or abutment portion 32 extend ng at an obtuse angle from the outer face of the hasp. V

A lock member 33 is secured to the auxiliary door 10 by means of rivets 34 extending through said member, the door and a backing member 35. The lock member is positioned upon a horizontal corrugation 13 of the auxiliary door and the backing member 35 lies within said corrugation. Additional rivets 36 are used to secure the lock member to the door. The lock member 33 is provided with a pair of vertically spaced housing members 3'7 and 38. A lug 39 extends from the lock member between the housing members. The housing member 37 is provided with an inward extension 40 positioned opposite to a downwardly and outwardly inclined portion 41 provided on the rear of the housing member. As clearly shown in Figure 7 of the drawings this down wardly and outwardly inclined portion of the housing member extends from the right hand portion of the housing member as viewed in Figure 7, stopping substantially midway between the ends of said housing member. The remainder of the rear of the housing member presents a substantially vertical wall. The lower housing member 38 is provided with a lug 42 extending downwardly therefrom. The outer end of the lower housing member is extended toprovide a flange 43 in which a slot 44 is provided. A shoulder 45 extends outwardly from the lock member adjacent said flange 43 in position to under lie the fastening pin 46 of the door look when said pin is in a predetermined position.

The fastening pin 46 is provided preferably with a straight side 47 adapted to abut against members 37 and 38 and an inclined side 48, the inclination of which corresponds to the inclination of the lug 31 provided on the hasp. The fastening pin is adapted to be received within the housing members 37 and 38 and to have vertical movement The inclined side of the outer face of the fastening pin extends at an obtuse angle from said pin as indicated at 49 and corresponds to the obtuse angle on the face 32 of the lug 31 of the hasp. The lower end of the fastening pin is provided with a lateral projection 50 in which an opening 51 is formed. Spaced vertically above the lateral projection is a shoulder 52. A head 53 is provided upon the fastening pin.

With a door lock of the character above described the fastening pin 46 must be assembled with the lock member 33 by insertion of the pin into the housing member prior to the securement of said lock member to the auxiliary door or other part of the car. This assembly is effected by inclining the pin rearwardly relative to the lock member so that the lateral projection 50 at the lower end or" the pin may be slid along the downwardly and outwardly inclined portion 41 at the rear of the upper housing member. After the assembly of the pin with the lock member and the attachment of said member to the auxiliary door it is impossible to completely release the pin from the lock member inasmuch as engagement between the lateral projection 50 and the shoulder 40 provided on the upper housing member prevents such retraction when the pin is in a vertical plane. The fastening pin cannot be inclined rearwardly, because of its engagement with the auxiliary door, a sufiicient amount to permit the pin to be Withdrawn along the downwardly and outwardly inclined portion of the upper housing member. As clearly illustrated in Figure 6 of the drawings, the pin in its inoperative position may be inclined forwardly so that the lower portion thereof engages the rear of the upper housing member and the shoulder 52 rests upon the inward extension 40. In view of this construction, it is not necessary for the operator to maintain the pin in retracted position while releasing or applying the hasp in proper relation with the lock member.

In positioning the hasp relative to the lock member prior to the projection of the pin in locking position the lug 39 of the lock member must be seated within the slot 30, provided in the hasp, in order that the fastening pin may be properly seated. This insures the projection of the pin in its locking position to such an extent that alignment between the slot 51, provided in the pin, and the slot 44, provided in the flange of the lock member, will be had so that a seal (not shown) may be extended through said aligned slots.

A certain amount of difficulty has been experienced with the lock or the hereinbefore identified co-pending application with regard to the tendency of the'tapered pin to creep upwardly to such an extent that the seal has, in a few instances, been broken.- The comtruction of the door lock of the instant application obviates this difiiculty. It will be apparent from a casual inspection of Figure 4 of the drawings that when the fastening pin 46 is maintained in a substantially vertical plane, engagement between the lateral projection 50, adjacent the lower end of the pin, and the lug 42, provided on the lower housing member 38, will occur prior to the breaking of the seal and prevent further upward movement of the pin. The shoulder 45 extending from the lock member and underlying the pin, aids in maintaining the position of the pin in a substantially vertical plane. However, in order not to interfere with the projection of the pin within the housing members and to permit release thereof, the coaction above described between the lateral extension 50 and the lug 42 may not be had if the pin assumes such position within the housing members that the lower edge thereof is positioned slightly above the shoulder 45. To provide against this contingency the obtuse angularity between the face 32 of the lug 31 of the hasp and of the tapered side of the fastening pin 46 is provided. It is clear, with such obtuse angularity of these parts, that there will be a: tendency to maintain the pin in a substantially vertical plane under the pull exerted upon the hasp when in its operative position. The possibility of upward creeping of the pin has been further minimized by the vertical inclination given to the lug 31 of the hasp and the side of the pin cooperating with said lug. As clearly illustrated in Figure 5 of the drawings the, straight side of the pin abuts against straight sides of the housing members 3'? and 38 in the operative position of the pin. This relationship between the pin, the hasp and the housing members has been found, through actual experimentation, to most effectively resist upward movement of the pin.

The structural embodiment of the invention may be subjected to many modifications and changes in the details thereof without departing from the spirit of the invention. It is intended, therefore, that all such modifications and changes shall be comprehended within the invention, which is to be limited only by the scope of the claims appended hereto.
