- Claims. (01. 292 -218) The invention relatesto fastening devices for doors.

The principal object of the invention is to generally improve structures of this character with 5 especial view to increasing their durability. While the invention is applicable to devices for use in doors of various structures, it is'illustrated in connection with refrigerator car doors,

Fig. 1 showing a. detail of the side of the car i I 10. in elevation, with'theimproved device applied thereto;

Fig. 2 is a sectional view on the line 2--2 of Fig. 1;

Fig. 3 is a sectional view on the line 3--3 of Fig. 1;

Fig. 4 is a detail section, onan enlarged scale, on the line 4-4 of Fig. 3;

Fig. 5 is a sectional detail on the line 5-5 of Fig. 1; and

Fig. 6 shows a group of the various parts of the device disassembled, in oneinstance partly -in section. Y

The side wall of the car is shown at 10, and its doors at 11, 12, the two doors being hinged to the sides of the door casing and closing together at the center line thereof. I

The door fastening device is of the well known type, comprising a vertical shaft journaled in bearings secured to the outer face of one of the doors and provided at each end with cams which cooperate with keepers secured to the car body rod one or both of the sockets are provided with bosses 17, 18, on two adjacent walls, which may be spaced apart longitudinally of the socket and preferably are of such height as to require the rod to be driven past them and slightly deflected, or the casting slightly expanded, to bring the rod into intimate contact with the opposite walls.

The outer end of each of the castings takes the form of a journal, as '19, 20, which fit within suitable journal boxes secured to the door adjacent to its top and bottom margins. These boxes may be of like construction; eachcomprising a base plate 21, havinga bearing surface 22, preferably interrupted between its ends, as shown; anda box section 23, provided with lateral flanges 24, having bolt-holes 25 which register with apertures 26' in the base plate. The length of these boxes is approximately the same as the length of the journals 19, 20.

At the outer end of eachof'these-joumals there is formed an integral cam element 2'7, which preferably takes the'form of a crank arm with a crank pin 28 projecting from its outer end, and being parallel with the journals 19, 20. The keepers cooperating with these cam elements are shown at 29, 30, and are generally of like form, each being provided with a slot 31, 32, oblique to the plane of the car side'and adapted to re- 10 ccive the pins 28 when the shaft is so turned that the arms 27, 27, project inwardly under and over the car door.

' The turning handle 33 is pivotally attached,

to swing vertically, to 2, lug 34, formed on the 78 I inner end of the lower casting 14, and is provided with a forked end'35 for engaging the rod 13 when the handle is raised. Preferably a journal box 36 is provided for the rod 13, and is secured to the door 11 approximately midway of its height. The socket of this box is circular in cross-section, its diameter being substantially the same as the major diameters of the rod, permitting the rod to turn freely within it but preventing, or greatly reducing, its vibration.

The handle 33 is provided with a socket 37 for receiving a lug 38, secured to the face of the door 12, with which cooperates a swinging keeper'39 for engaging over the handle when the doors are closed, the lug 38 and keeper 39 being provided with suitable apertures for receiving the strap of a sealing device, the structure being the same as that shown in Patent No. 968,190, of August 23, 1910.

Apertured lugs 40, 41, are secured to the outer 93- faces of the doors 11 and '12, near their margins, each cooperating with a gravity latch 42, pivoted within a box 43 attached to the side of the car, the latch'being provided with a bevel face 44 for engagement by a wall of the box 41' as the door swings to fully open position, and with a handle 45 by which it may be manually released.

A body of the lower keeper 29 is laterally extended, as shown at 46, this extension being laterally slotted, as shown at 4'7, to receive a latch 48, which is pivoted within the slot to swing vertically and serves to secure the door 12 in closed position, as plainly indicated in Fig. 1, this latch being manually turned upwardly and beyond the horizontal after the doors are closed.

margin. The door 12 may be now swung on its' hinges, the latch 48 being first released. Upon the closing of the door 11 the pins 28 enter the throats of the slots 31, 32, and the shaft, being now turned, the handle 33 being turned to engage the lug 38, the pins 28- engage the outer walls of the slots 31, 32, and cam the door 11 to completely closed position. a

By pivoting the handle 33 upon an integral lug of the casting 14, and providing it with a fork for engaging the rod 13, a strong construction is secured in that the turning stresses are applied to both the casting and the rod and certainty of action is insured, as the tendency of the comparatively light and quite long rod to twist is obviated.

I claim as my invention-- a 1. In a door fastening device, in combination, a sectional shaft comprising a square rod and and pieces having sockets in their inner ends complementary in form and size to the rod for receiving the ends thereof, two adjacent walls of the sockets having instanding-bosses for deflecting the rod as it is inserted, and provided with cam elements at their outer ends, keepers for the cams, and a handle for turning the shaft.

2. In a door fastening device, in combination, a sectional shaft comprising a square rod and end pieces having sockets in their inner ends complementary in form and size to the rod for receiving the ends thereof, two adjacent walls in cross-section and end pieces having sockets in their inner en'ds complementary in form and size to the rod for receiving the ends thereof, two adjacent walls of the sockets having instanding bosses for deflecting the rod as it is inserted, and provided with cam elements at their outer ends, keepers for the cams, and a handle for turning the shaft.

4. In a door fastening device, in combination, a sectional shaft comprising a rod rectangular in cross-section and end pieces having sockets in their inner ends complementary in form and size to the rod for receiving the ends thereof, two adjacent walls of the sockets having instanding bosses for deflecting the rod as it is inserted, such bosses being at different distances from the end of the socket and provided with cam elements at their outer ends, keepers for the cams, and a handle for turning the shaft.

5. In a door fastening device, in combination, a sectional shaft comprising a rod rectangular in cross-section and end pieces having sockets in their inner ends complementary in form and size to the rod for receiving the ends thereof and provided with cam elements at their outer ends, keepers for the cams, and a handle for turning theshaft, such handle being pivotally attached to the lower end. piece to swing vertically and having a forked end for engaging the rod when in horizontal position.
