FASTENING DEVICE FGR CAR-DOORS.

Specification of Letters Patent.

Patented July 6, 1915.

Application filed January 29, 1913. Serial No. 745,001.

To all whom it may concern:

Be it known that we, EDWARD A. NIX and EUGENE G. RODDIE, both citizens of the United States, residing at the city of New Orleans, in the parish of Orleans and State of Louisiana, have invented. certain new and useful Improvements in Fastening Devices for Car-Doors, of which the following is a specification.

This invention relates to refrigerator car door fasteners.

One object is to provide means for fastening refrigerator car doors together tightly so as to render the car perfectly air tight and to accomplish this advantage without the necessity of pounding the doors together or necessitating a crow-bar or other device for prying them open.

Another object resides in the provision of a door provided with fastening means which may be actuated for opening or fastening the door through the instrumentality of a single lever.

With the above and other objects in view the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that changes may be made in the form. proportion, size and minor details without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a side elevation of a portion of a car illustrating our fastening means in operative position. Fig. 2 is a horizontal sectional view on the line a-a of Fig. 1. Fig. 3 is a horizontal sectional view on the line b?) of Fig. 1. Fig. 4 is a vertical sectional view.

Referring now more particularly to the accompanying drawings the reference character 10 indicates a portion of the side of a car provided with a door opening 11 to the sides of which are hinged the doors 12 and 13. The free longitudinal edges of these doors are preferably beveled as indicated at 12 and 18. respectively. so that they may have overlapping relation when closed. Suitable packing 14 is secured in any suitable manner to the beveled edge of the door 12.

J ournaled in suitable brackets 15 on the door 13 is a rod 16 which is rotatable about its axis by means of the lever 17 secured adjacent the lower end of said rod.

Fitted in the side of the car over the doors is a casting 18 having a recess 19. A roller 20 is disposed adjacent this recess 19, being journaled on the bight portion 21 of the U- shaped bracket A whose legs 22 pass through the side of the car and on the free ends of which nuts 23 work in order to secure said bracket in rigid position.

Fitted to the side of the car below the doors in line with the casting 18 is a casting 24 provided with a recess 25. Adjacent this recess 25 is a roller 26 journaled on the bight portion 27 of the bracket Z) whose legs 28 extend through the side of the car and the bracket 6 is held by nuts 29 connected to the inner ends of the legs of the bracket.

The opposite ends of the aforesaid rod 16 are tapered and curved into substantially crescent shape to provide upper and lower hooks 30 and 31 designed to engage in the respective recesses of the upper and lower castings 18 and 24. By manipulating the lever 17 the rod 16 may be rotated to throw these hooked ends into and out of said recesses. By throwing said lever toward the staple 32 secured to the door 13 the hooked ends of the rod are thrown into said recesses and into embracing relation with the rollers and, by virtue of a consequent cam action between the hooked ends of the rod and the rollers, the doors are forced tightly into overlapping relation with the free longitudinal edge of the door 13 binding tightly against the packing at the free longitudinal edge of the door 12.

A hook 33 may be carried by the lever 17 for engagement in the staple 32 to prevent the doors from being accidentally jarred open. If desired, a seal (not shown) may be used to fasten the doors against surreptitious opening.

The rollers furnish a rolling contact, which facilitates closing the doors because it reduces friction to a minimum. Moreover, when it is desired to open the doors, the same lever that acts to force the doors together acts to facilitate opening the doors. When the lever 16 is swung away from the staple 32 it rotates the rod backwardly to disengage the hooked ends of the rod from embracing relation with the rollers adjacent the recesses of the aforesaid upper and lower castings.

A ledge 34: is preferably secured at the side of the car immediately above the car door opening for the purpose of shedding Water but this feature is not material to the present invention.

Some of the advantages that may be enumerated are that the doors may be padded as much as desired provided the doors may be brought sufliciently close together for the hooked ends of the rod to engage the rollers. The rollers furnish a rolling contact which insures an efiective tight closing of the doors. Another feature resides in the provision of a single lever for effecting a locking and unlocking of the doors, that is to say, by throwing the lever in one direction the doors are effectively locked together, and by throwing it in the opposite direction the doors are readily opened. This particularfastening means obviates the usual damage done in pounding doors together and also the damage usually done by virtue of crow-bars and otherinstruments used for the purpose of prying the doors open.

l/Vhat is claimed is:

The combination of a casting adapted to Copies of this patent maybe obtained for five cents each, by addressing the Commissioner of Patents.

be secured to the side of a car or the like, said casting having a recess provided therein, a rotatable rod adapted to be secured to the door of the car or the like, a hooked terminal formed upon the said rod for insertion in the recess of the casting, a U-shaped bracket having its opposite sides passing through said casting and its arch disposed EDWARD A.
