UNITED STATES IVER I BENDIKSON, Q15 MANDAN, NORTH DAKOTA.

CAR DOOR.

Application filed April 8, 1924. Serial No. 705,093.

To all whom it may concern Be it known that I, Ivna P. BENDIKSON, a citizen of the United States, residing at Mandan, in the county of Morton and State of North Dakota, have invented certain new and useful Improvements in a Car Door, of which the following is a specification.

This invention relates to improvementsin car doors particularly designed for freight cars.

An important object' of the invention is to provide a new and improved car door which may be slidably mounted upon a freight car and securely held in position thereon.

A further object of the invention is to provide a door of this character which will not become opened or loosened caused by j arring of the car while traveling over the rails.

A still further object of the invention is to provide a door of this character which may be opened or closed with little difficulty and at the same time insure a tight connection.

A still further object of the invention is to provide a door of this character which is comparatively simple 1n construction, although very durable and efficient for this purpose. I

Other objects and advantages of this invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 illustrates the door embodying my invention mounted on the side of a freight car,

Figure 2 is a similar view showing the door in partially opened position,

Figure 3 is a top plan view of my 1mproved door,

Figure 1 is a horizontal section taken on the line 4:4: of Figure 1, I

Figure 5 is an end elevation of my inven tion, and

Figure 6 is a vertical sectional view taken on the line 6-6 of Figure 1.

In the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 10 generally denotes the side of a freight car which may be used for transporting cattle,

grain or any merchandise usually transported. in en in ers. Myjrnproved door structure generally denoted the numeral 11 eensista er a plurality of longii'yiidinal fgitaiiks 12 securely fastened by means of a plurality of upright connecting planks .13. I do not wish to limit my invention to this construction however as the door may conceivably be constructed as a solid sliding partition, the construction depending upon the form of merchandise to be carried in the freight car. The type herein illustrated being particu larly adapted for stock care, while I do not wish to limit my invention to this particular application and conceive of applying the door to grain cars and the like. The type of door shown in the accompanying drawings is adapted to slide within a suitable frame built in the side of a freight car and embodies novel securing features.

Mounted in the central portion of the door I provide a sliding bar 14 which is preferably circular in cross section and is actuated by a substantially U-shaped handle lever 15 which extends outwardly beyond the upright members 13 and has its extremities secured to the bar 1 1. A pair of longitudinally extending bars 16 are secured to the three uprights positioned in the frontportion of the bar and are preferably constructed of metal forthe purpose of reinforcing the structure of the door. The front pair of uprights 13' each carry a pair of raised guide bars 17 adapted to permit movement of a pair of swinging arms 18. The swinging arms 18- are pivotally connected to the center upright near the upper and lower extremities thereof, and have an enlarged engaging head 19 formed on the front extremity provided with a rectangular opening in the center.

The swinging arms 18 each carry a pair of tapered bars 20 pivotally connected to the arms as at 21 and adapted to swing therewith. As it is intended to retain the tapered bars 20 in a substantially vertical position I provide a pair of blocks 22 and 23 secured against the uprights 13 to prevent displacement of the said tapered bars: The forward upright of the door carries a pair of arcuate levers 24 positioned near the upper and lower extremities and hingedly secured to the upright by means of straps 25 and pins 26. The inner extremities of the levers 24L carry a pair of swinging bolts 27 hingedly connected to the levers. The outer extremities of thearcuate levers 24 are turned outwardlyas at 28 to form actuating, clips to ermit, the levers to be readily swung about t eir' "lvtit pins.

(rte bane 2? adapted as engage sate 2 reraeoo able sleeves 29 formed on the outer portion of brackets 30 secured to the door frame. In order to prevent n'iovement oi the levers when in the closed position I provide a pair of swinging cam members 31 pivoted adjacent the levers and adapted to be positioned in the retaining straps 25 and prevent displacement of the levers whereby the bolts 27 are held in the sleeves 29 as shown in Figure 1.

The upper portion of the door frame has a. metallic strip secured thereon, the outer extremity being turned to provide hinged joints. A swinging plate 33 has coacting turned edges adapted to align with the said hinged joint and adapted to receive a circular hinge rod 34: forming an axis about which the plate 33 may be rotated. The turned edges of the co-acting plate are constructed to permit a space to be formed between the supporting strip and hinged plate thus enabling the plate 33 to be moved longitudinally as well as swung easily about the rod. The swinging plate 38 is provided with rectangular openings 2-56 adapted to receive the extremities of the tapered bars 20 one edge of the opening being provided with a tapered slot for the purpose of receiving the shank of a pair of retaining bolts 37 secured to the door and provided with enlarged heads 38. A retaining knob is also secured to the metallic strip as denoted by the numeral 39 and is adapted to engage a swinging latch 40 pivoted to the plate 32 for the purpose of preventing movement of the swinging plate in closed position. r

The lower extremity of the door frame carries a bracket 4-1 bolted or otherwise secured thereto, intermediate portions of the bracket being bent outwardly as at 42 for the purpose of receiving the lower tapered bars 20 and assisting the door closure. In order to prevent movement of the U-shaped handle lever 15 I provide a hinged bracing plate 4:3 hingedly mounted upon the central upright and provided with a recess 4% at its extremity, the said recess being adapted to engage the handle lever 15 in the closet po- 'sition. A pair of extending prongs are formed on the extremity of the bracing plate 4:3 and rest upon the longitudinal bars 16 when the plate is in the closed position and engaging the lever 15. The end jamb of the door frame is provided with a groove in the central portion thereof covered by a cover plate 45 secured in the central portion of the jamb and adapted to receive the circular bar 14.

In operation, when the car is being transported the locking devices are in closed position and securely retain the door in position. lVhen it is desired to open the door as shown in Figure 9 the bracing plate 13 1S swung outwardly permitting the U-shaped lever 15 to be moved longitudinally toward the rear of the door and releasing the bar 1 1 from the door frame. The next operation consists in swinging the cam members 31 away from the retaining straps 25 and swinging the arcuate levers 2d causing the bolts 27 to be withdrawn lirom the sleeves 29. The arms 18 which have their extremities positioned over the sleeves 29 are then forced upwardly and released from the sleeves and. swung toward the center of the 'door carrying the tapered bars 20 there with and releasing them from the bracket 41 and plate 33, the plate 33 being forced longitudinally thus releasing same from the bolts 37 and freeing the door.

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same, and that various changes as to the shape, size and arrangen'ient of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
