I Application filed January 6, 1915. Serial No. 733.

To all whom t may concern Beit known that I, WILLIAM O. THoRr, a citizen of the United States, and a resident of Brainerd, in the county of Crow wWing and State of Minnesota, have made certain new and useful Improvements in Doors, of which the following is a specification.

My invention is an improvement in doors, and has for its object to provide a door especially adapted for use as a grain door in freight cars, wherein the door is sectional, and the sections are movable with respect to each other to provide for various widths of door openings,` and wherein each section has means at its outer end for engaging the sides ofthe door opening to prevent lateral movement of the door, and wherein means is provided for moving the sections and for holding them in adjusted position.

A further object is to provide mechanism for permitting a portion'of the contents of the car to escape by way of the door opening, to relieve the pressure on 'thel door to permit the same to be opened.

ln the drawings: Figure 1 is a front view from the outside of the improved door, Fig. 2 is a top plan view of the door, and Fig. 3 is a section on the line 3-3 of Fig. 1 looking in the direction of the arrows adjacent to the line.

ln the present embodiment of the invention the door is sectional, the sections beingformed of sheet metal of suitable weight and size, and the sections are mounted to slide' longitudinally with respect to each other. rThe sections 1 and la of the door are lapped upon each other at their inner ends, and at the outer end of each section a portion 2 or 2ZL of the material of the door is oifset laterally, being connected to the section by an integral web 3 or 3a as the case may be.

rlFhe upper and lower side edges of the section 1 of the door are bent'over upon the body of the door in spaced relation, as indicated at 4 and4 5 respectively, lto form guideways for receiving the adjacent side edges of the section 1, and the said section 1a slides in the guideways. A lever 6 is pivoted to the outer face of the section 1 near the lower edge thereof, and at the lower end of the lever, as indicated at 7,and the lever is provided with the usual latch lever 8, pivoted to the upper end thereof, and connected by a link 9 with a latch 10 mounte normally pressed downward by a spring 12 arranged between the latch and one of the bearing lugs. The latch is adapted to engage one of a series of openings 13 in an arc-shaped or curved guard 14, the said guard having its ends offset and given a quarter turn, as shown at 15, and the said portions are superposed on the outer face of the body of the section 1 and are secured thereto by rivets or bolts 16.

The lever moves between the guard and the door section, and a pair of links 17 are connected at one end to the lever intermediate its ends, and between the guard 11 and the pivotal connection 7 of the door. The links are varranged on opposite sides of the lever, and at the other end the body 18 of a yoke is received between the links, and is pivoted thereto, as indicated at 19.

The arms 2 0 of the yoke diverge from each other for some distance and then extend parallel, as indicated at'21, and the parallel portions are secured to the section 1a of the door near the end remote from the other section 1. It will be evident from the description that when the lever 6 is released from the guard and swung in the proper direction, the sections 1 and 1a will be moved longitudinally with respect to each other to lengthen or shorten the door.

Doors of the character in question are as a rule connected to the car and are mounted to be lifted vertically into inoperative position, or to swing inwardly. Each car has its own doors, the doors being made'to fit the car. The present door, however, can be made to fit door openings of different sizes, and the door is intended to be placed as shown in Figs. 2 and 3, that is with the body of the door between the framing posts 22 of the door opening and with the webs 3 and 3 engaging the adjacent faces of the framing posts, and with the portions 2 and 2a 4fitting the inner .faces of the framing posts.

Since all of the stress upon the door is from within, the door would be firmly held by the manner of its engagement with the framing posts of thedoorway. Additional means is provided, however, for securiig the door in place, the said means comprising a pair of spurs or lugs at each end of the door and connected to each section. Each of the spurs or lugs 23 is pointed, or sharpened, and each spur or lug has a Hattened or plate like portion 24 which is secured to the adjacent section of the door, The spurs or lugs are arranged near the top and the bottom of the door, one pair at each end as before stated, and the said spurs orlugs as will be obvious, move with the sections. The spurs or lugs extend beyond the webs 3 and 3a some little distance, as shown, and the spurs or lugs proper are designed to engage within the material of the framing post.

In use, before placing the door it is contracted, by swinging the lever toward the left of Fig. 1, andinto the position of Fig. 1. In this positionthe door is at its shortest length, and with the parts so arranged, the door-is placed between the framing posts, with the ends of the offset portions 2 and 2a resting against the inner faces of the framing posts. The lever 6 is now released from the holding sector 14,,and the said lever is swung to the right of Fig. 1, thus moving the sections longitudinally with re spect to each other and outwardly. As the sections move away from each other, the webs 3 and 3a will finally Contact with the adjacent faces of the framing posts, the pointed spurs or lugs entering the material of the framing post to rigidly lock the door in position. The lever 6 is locked with the sections in adjusted position and they lcannot become displaced until the lever is released from its holding mechanism.

When cars are loaded with material in bulk, as for instance grain, coal or other minerals, the pressure of the material against the grain door makes it difficult to move the sections with respect to each other, or to move the door as a whole. In order to permit this pressure to be wholly or pan tially relieved before removing the door, the door section 1 is provided with an opening 25 near its lower edge, and near the center of the door.

Guideways 26 are arranged horizontally above and below the door opening, the said guideways being parallel, and a door 27 is mounted in the guideways for movement over and away from over the door openings. The door is provided at the side edge remote from the lever 6 with a perforated lug 28 and one end of a link 29 is pivoted to the lug. The other end of the link is pivoted to a lever 30 intermediate the ends of the lever, and the lever is pivoted at its'upper end to the section 1 of the door, as'indicated at 31. The lower end of the lever is provideo` with a knob or handle 32 for convcnience in manipulating the lever, and it l will be evident that by swinging the lever in the proper direction the door will be moved in its guideways to uncover the door opening 25. When the door is opened, the material is free to run out at the opening 25, and a sufficient amount will pass out to relieve the pressure on the door proper to permit the sections to be moved toward each other and to disengage them from the framing posts.

The improved 'door may be quickly and easily replaced or removed, and when in place it is an absolute bar to the escape of anything. Neither is it necessary to provide complicated supporting mechanism for the doors. Since the door is of sheet metal, it will last indefinitely, and since there are no complicated parts to get out of order the up-keep will be small.

It will be noted that a slot or opening 33 is provided in the lever G for receiving a seal, to prevent or rather to indicate tampering with the door by unauthorized persons.

It will be understood that the improved door may be connected with cars of different types, and since there is no permanent connection between the door and the car, the

4doors may be used in different cars, that is,

they may be transferred from one car to a11- other. Neither is there any special fitting required in the car, such as openings for the spurs 23. for the spurs are capable of making openings for themselves.

I claim: I

A freight car door adapted to be applied to the ordinary doorway of a freight car and composed of two metal plates sliding one upon the other, the upper and lower edges of one of the plates being bent over the like edges of the other, whereby the plates are held together telescopically, each of said plates being provided at its outer end with an inwardly offset portion having an intermediate shoulder or flange to abut the doorway wall and a rigid extension flange to lap Within the doorway, spurs on both of said plates near their upper and lower edges and projecting beyond the Shoulder of the offset portions and adapted to be forced into the wall of the doorway, a lever pivoted to one of the plates. and means connecting said lever to the other plate, all substantially as and for the purpose set forth.
