WILFRED A. BEA'UCHAMP rAND KENNETH J. TOBIN, 0F CHICAGO, ILLINOIS, ASSIGNORS y TO CAMEL COMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION 0F ILLINOIS DOOR-LOCKING MECHANISM FOR HOUSE CARS Application filed July 16,

This invention relates to door locking mechanism for house. cars.

In they past, a slidable sealing pin has been used for locking the doors of house cars. 5 This pin was slotted and supported by a rivet extending through the slot. The heads fof j these rivets frequently crystallize and oXidize in service and snap off during the operation of the locking pin with the result Further, in producing such pins a molding process is `required which produces many imperfect pins due to shrinkcracks, hard shots, etc.

This invention is designed to overcome the above noted objections in the provisionof a pinless locking mechanism which avoids the use of a sealing pin, which canbe readily forged and hence more cheaply manufactured and which may be designed to lock the car door in partly open position for Ventilating purposes.

The invention comprises the novel strucr ture and combination of parts hereinafter o described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate certain preferred embodiments of this invention and in which similar reference numerals referto similar features in the different views:

Figure 11 is a front elevational view of a part of the mechanism shown in Figure 3.

Figure 12 is a sectional view taken on the line XII-XII of Figure 11.

Referring to Figures 1, 2, and 4 which illustrate the preferred form of this invention, it will be observed that a pair of sliding doors 1 and 2 have been illustrated in connection with this locking mechanism. The locking mechanism consists of a stationary member 3 secured to one door. This stationary member is provided with a stud 4 having an enlarged head 5 which is comparatively narrow. In parallel relation with the stud 4 there is an upstanding lug 6 providedd 70 with an aperture 7, as shown in Figure 12, for a purpose that will later appear.

Upon the other door there is secured a hasp fastener 8 which consists of a narrow metal strip having a hook-shaped end 9 which 75 forms a pivot upon which a locking hasp 10 is pivoted to swing in its plane. The hasp 10 is provided with an arcuate slot 11 having opposed notches 12. The hasp 10 is also provided with an upstanding lug 13 having an aperture 14 (Figure 4),

When the doors are closed, the hasp 10 is swung over the headed stud 4.--5 until the notches 12 register with the head 5 of the stud when the hasp may be pushed over the head of such stud until the shank thereof en- ,gages in the arcuate slot 11. The hasp is then swung until the lugs 13 and 6 come into contact and a sealing wire may be inserted through the apertures of such lugs for seal- 799 ing the car doors. `With reference to Figure f hasp to provide a hasp 10a having a plurality ofv slots 11' With notches 12. Adjacent each '5100 slot there is a lug 13 for cooperation with the lug 6 on the locking member 3 which is-also provided with a headed stud 5, as in Figure 1. The hasp 10a is likewise pivoted upon a support 8. The feature of elongating the hasp allows the doors to be locked and sealed in partially open positions, as shown in Figure 3, for Ventilating purposes. In such position the more remote slot 11 from the pivot i of the hasp is engaged with the stud 4-15. If

it should be desired to lock and seal the door in closed position the first slot 11 from the pivot of the hasp will, of course, be used to engage the pivot stud 4-75. And as each slot 11 has a lug 13 adjacent its inner end for coaction with the lug 6, thelocking mechanism Vmay be sealed in either position.

In Figures 5 to 9 a further modification of .the invention is shown. In this modification there is shown a locking member 3awhich is adapted to be secured on onev of the doors 1 and 2. In the present instance it is shown attached to the door bearing the reference 2. This locking member is provided with a stud 14 which is headless and a lug 15 having an overhanging flange 16 and a closed wall 17 upon one side, whereby a housing is formed which is open upon the side opposite the wall.

The overhanging wall 16 has a depending lip 18 at its end which is adjacent the opening to .the housing whereby a recess is formed. The lug 15 is provided with an aperture 19 for a In locking the doors according to this last modification the hasp 20 is swung over the stud 14 so that said .stud will engage in the slot 21; The hasp 2O is then swung to bring the lip or lug 22 within the confines of the lug 15, as shown in Figures 6 and 7. In this position the latch 2O is restrained from upward movement by the lipy 16 and from .lateral movement by the wall 17 and lip 18. It

-might be mentioned that the hasp 20 is slightly y'elevated to bring the aperture 23 into reg-` istry with the aperture 19. This elevation of the hasp will bring the lip or lug 22 in alignment with the lip 18.

In the form of the invention shown in Figures 5 to 9 the hasp ycould not be elongated as in the form shown in Figure 3 for the reason that the sealing lugs 15 would be in the way. In the modifications shown in -Figures 1 to 3, however, the sealing lugs are located upon one side so that an extension of I the hasp is possible. It should be noted that inall forms ofthe invention the hook shaped end 9 ofthe hasp fastener is in thesame horizontal plane with the pin 4 or 14. Consequently, when the dooris locked, the complete strain will be absorbed by the hook 9 and the pin 4V or 14 with the result that there will be no tendency to rupture the sealing wire and allow the hasp to work olf the pin and drop down. .A

It will be appreciated that this locking mechanism eliminates the oldform of sealing yand locking pin that has been used inthe past and that has proved unsatisfactory. Moreover, it reduces theparts of the lockingmechanism. In the present instance but two parts are used and there is practically no liability of either part being lost or thrown away as occurred inthe use of the sealing pin.

We are aware that many changes may beY made, and numerous details of construction tured abutment forsealing purposes, the pivotal axis of said hasp being substantially in the same horizontal plane as said stud whereby aV straight horizontal tained upon said hasp. 2.k In a latching mechanism for car doors, a stationary member having a stud and a lug with an overhanging lip, a hasp having a pivotal axis in substantially the same horizontal plane'as the stud and having'anl arcuate slot, for engaging said stud, said hasp having a lug engaging'under. said lip, said lugs being apertured for receiving a sealing wire. A3. In a latching mechanismfor car doors, a stationary member having a stud and a lug with an overhanging lip and an end wall, a hasp having a pivotal axis inA substantially the saine' horizontal plane as said'stud and having an arcuate slot for engaging said stud and an abutment for engaging under the lip Y I of said lug'and abutting the end wall, said lug and abutment having a passage for a sealmg wire. A

4. vIn a latching mechanism for car doors, a stationary member having a stud and a lug with a recess adjacent said stud, a hasp havving a pivotal axis in substantially the same horizontal plane as the stud, a slot for engaging said stud and a lug for fit-ting the recess of the first-mentioned lug, said lugs having a passage for a sealing wire. p

In testimony whereof, vwe have hereunto subscribed our names at Chicago, Cook County, Illinois.
