This invention relates to locks for car doors.

It is an object of the invention to provide a lock for car doors by whichsaid doors may be forced into their fully closed position.

A further object is the provision of a lock for car doors, which will insure maintenance of said doors in fully closed position.

Other objects of the invention will become apparent from the following description thereof:

In the drawings forming a part of the specification, Y

Figure 1 is a fragmentary elevation of a car door lock embodying'this invention in its application to a double door construction, the lock being shown in operative position.

Figure 2 is a view similar to Figure 1, illustrating the lock in inoperative position.

Figure 3 is a view similar to Figure 1, showing the hasp of the lock in operative position and the locking pin partly withdrawn to better illustrate the relationship of th pin and the hasp.

Figure 4 is a sectional view taken on line 44 of Figure 1.

Figure 5 is a sectional view taken on line 5 5 of Figure 6.

Figure 6 is a sectional view taken on line 6`6 of Figure 4.

In the drawings the preferred embodiment of the invention is shown in its application to a double door construction. It is to be Vunderstood, however, that the lock is not limited in its application to such double door .construction but is capable of utility as well with asingle door construction. In the double door structure illustrated there is provided a main door 10 and an auxiliary door 11. The auxiliary door may be supplied with a jamb 12 movable therewith and in which a filler post or nailing stri-p 13 may be seated. Stiffeners 14 may be utilized in the main and auxiliary doors.

Applied to the auxiliary door 11 is a lock 1931. Serial No. 530,508.

plate 15 which may be secured thereto by means of a plurality of rivets 16-16 extending through said lock plate, the door and a backing plate 17. The lock plate is provided with a guideway 18 adapted to slidably receive a locking pin 19. The lock plate 15 is further provided with a pair of vertically spaced ianges 20-21 extending forwardly thereof and connected by means of a retaining wall 22 which lies in spaced relation to the lock plate.

Secured to the main door 10 by means of a plurality of rivets 23L is a hasp fastener 24. The rivets 23 extend through said fastener, the door and the backing plate 25. Said fastener is preferably provided with a forwardly extending boss 26 upon which a hasp 27 is adapted to be supported. The hasp 27 is provided with an elongated slot 28 whereby said hasp vis adapted to have bot-h pivotal and sliding movement relative to said boss. The hasp is retained in position upon the boss by means of a washer 29 retained in position by means of a rivet 30. On the face of the hasp presented toward the door a recessed portion 31 is provided. By means of this recessed portion there is presented a pair of spaced substantially

vertical walls

32 and 33, respectively, the latter of said walls or abutments being positioned preferably adjacent the free end of said hasp and being inclined.

The locking pin 19, as hereinbefore pointed out, is slidably retained in the guideway 18 provided in the lock plate 15. The pin 19 is additionally retained against removal from the guideway 18 by means of a boss 34 extending from said lock plate and through an elongated slot '35 formed adjacent the lower portion of said pin. A washer 36, larger in diameter than the width of the slot formed in the pin 19, is retained against the boss by means of one of the rivets 16, thereby preventing withdrawal of the pin from the guideway formed in the lock plate. Intermediate the ends of the pin a projection 37 is formed, this projection having spaced walls 38 and 39, the latter being inclined to the vertical in conformity with the inclined wall 33 provided on the hasp. The upper end of the pin is formed with a flange portion 40 and a door.

In order to close a door opening provided in a house car by means of the doors n and 11 the auxiliary door 11 will first be moved to closed position. The 1main d oor will then be moved toward closed position. Assuming,

however, that the main door cannot be moved to its fnlly closed position the lock construction above described may'be'utilized Afor this purpose within the limits of thelo'ck To accomplishithisi'resultthe hasp'may be moved to' t e position shown in'dot and dash lines in Figure 2 of .the drawings and then moved substantially horizontally until it is positioned in supporting relationship'upon the flange 21 and'bet'wieen the retaining wall 22 andthe lock plate.v Prior to this placement pf `the hasp the pin 19 will have been elevated to the position shown in Figure 2 `of the drawings, the pin yin thisv movement lpassing through a recess Il., -,clearly shown in Figure 6 of the dra-wingsv andl formed in tlieu'pper flange 2O iof the lock plate. The pin will then be lowered until the projection 37 provided thereon .enters the recessed portion 31 formed in the hasp.y The ,pin may ythen be driven downwardly during which 'movement the hasp and, consequently, the ldoor to which it is secured will be forced to fully closed position. This is effected by n ieans of .the engagement between the inclined vWall l39 formed yon the projection 37 and the inclined ,wall a3 3 provided yby the recessed portion 31 on the h asp. For the purpose of driving said pinto home position the fia-nge 40 is fplvidd at the Yupper end thereof. It is apparent that when said door has once been drawn to its fully closed position it will be rigidly retained in such position against back-andforth movement when the l'car is .inv transit. It is manifest froml Figure 4 of the drawings that because of the engagement between the right hand Aend of the lhasp andV the boss ,formed Ion the hasp fastener nomovenient of the door toward the right can result. YFuitlierinore, inasn'iuohas the twoV d oors as shown in this figure are no w in engagement the door 10 cannot move toward' the left; y i

llVhilea preferred embodiment vof this inf vention has been set forth it is to be understood that the invention is not to limited to the details of construction shown. It is intended that all changes and modifications falling within the spirit of the invention are covered herein and that no limitations other than those included in the claims appended hereto are to be imparted to this invention.
