CAR.

SPECIFICATION forming part of Letters Patent No. 693,132, dated February 11, 1902.

Application filed December 3, 1900. Serial No. 38,526. (No model.)

To all whom, it may concern.

Be it known that I, AXEL HEIDEN, a citizen of Norway, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Cars, of which improvements the following is a specification.

In an application for Letters Patent filed April 3, 1900, Serial No. 11,375, I have described and shown certain improvements in hopper-cars, such improvements being especially directed to the arrangement and means for operating the hopper-doors. The invention described herein relates to further and additional improvements in hopper-cars and doors therefor.

In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view of a car having a discharge-hopper arranged longitudinally of the car and the hopper-doors swinging laterally of the car. Fig. 2 is a similar View of a car having two longitudinal hoppers and laterally-swinging doors. Figs. 3 and 4 are transverse sections on a plane indicated by the line III III, Fig. 1, the doors being shown closed in Fig. 3 and open in Fig. 4. Figs. 5 and 6 are transverse sections on a plane indicated by the line V V, Fig. 2, the doors being shown closed and open in the respective views. Fig.7 is a top plan view of a portion of a car having transversely-arranged hoppers and doors, portions of the body of the car being broken away. Figs. 8 and 9 are side elevations of thecar shown in Fig. 7, showing the doors in open and closed positions; and Fig. 10 is a transverse section on a plane indicated by the line X X, Fig. 7.

In the construction shown in Figs. 1, 3, and 4 the portions 1 of the floor of the car incline downward from the ends of the car to the discharge-opening, and the portions 2 of the floor incline downwardly from the sides of the car to the discharge-opening. The sides of the hopper are formed by channel-bars 3, to which the inner edges of the floor-plates 2 are riveted, said bars extending to or toward the ends of the body of. the car and being socured thereto. The ends 4: of the hopper are formed by bending down portions of the floorplates 1 and by riveting additional plates to These doors are suspended from the channelbars 3 by securing portions of their hinges to said bars, as shown in Figs. 3 and 4. An arm 7 is secured to one of the doors, as 5, preferably at a point midway of a brace secured to the doors near their ends, and the opposite end of said arm is connected to one arm of a bell-crank 8 by a rule-joint, said bell-crank being pivoted to the side of the car. The other arm of the bell-crank is loosely con nected, as by the link 9, to an arm 10 on the shaft 11, mounted in suitable bearings transversely of the car. One end of the shaft projects beyond the side of the car and is made angular in cross-section for the reception of an operating-handle. A disk 12, provided with a notch, is secured on the shaft, and a pawl 13, having a hook to engage the notch, is pivoted to the side of the car, said parts being so arranged as to lock the door-operating mechanism when the door is closed or open. The pawl is weighted, so that when free to move its hook will be drawn from ongagement with the notch in the disk. The pawl is held in locked position by a camplate 12, mounted on the side of the car. It is preferred to so construct and connect the bell-crank and the arm 7 that their pivotal connection will be slightly out of line and above the pivotal connections of the arm to the door and the bell-crank to the car, so as to form a practically'rigid brace between the door when closed and the side of the car. It is also preferred to connect the pivotal joint between the arm 7 and the bell-crank to the arm 10 by a link 14:, which may be formed integral with the arms of the bell-crank, as shown in Figs. 3 and 4. Arms 15 are rigidly secured to the doors 5 in such position as to move outside of the ends of the hopper and have their free ends connected by links 16 to the doors 6, whereby the opening and closing movements of the door 5 will cause a corresponding movement of the doors 6.

In the construction shown in Figs. 2, 5, and 6 the inclined floor-platesl do not extend to the discharge-opening, but are provided with apron-like extensions 17, which reach to the discharge-opening. A longitudinal ridge extends from the floor-plate at one end of the car to that at the opposite end and is formed by channel-bars 3 and by plates 18, secured to the channel-bars and having their upper edges riveted together, forming the apex of the ridge. The channelbars are secured to the end sills or bolsters 12 of the car, as shown at the left in Fig. 8. The inner doors 5 are suspended from the channel-bars, one member of the door-hinges beingsecured to the channel-bars. Arms 7 are pivotally connected and have their outer ends pivotally connected to braces 19, whichhave their ends secured to the doors, as described in the application referred to. The pin'connecting the arms together is connected by a link 9 to an arm in the shaft ll,which extends transverse of the car and is operated as heretofore described. The car is braced and strengthened by transverse ridges 20, which extend from the sides of the car to the longitudinal ridge, as clearly shown in Figs. 2, 5, and 6. By the employment of the channel-bars 3 and arranging them along the middle portion of the car the side sills heretofore employed can be dispensed with,

' thereby permitting of an enlargement of the discharge-openings transverse of the car; and, further, by arranging the doors so as to swing laterally a longer opening can be formed than is possible where the doors are arranged transversely of the car.

As shown in Figs. 7, 8, and 9, the supporting channel-bars 3 may be substituted for the side sills in that kind of cars which have their doors arranged transverse of the car, thereby permitting of an' increase in the dimension of the discharge openings transversely ofthe car. In the construction shown in Figs. 7, 8, and 9 the inner doors 5 are connected by hinges to the walls of the transverse ridges 20 in such manner that when the doors are in closed position the doors form continuations of the ridge-walls, as shown in Fig. 8. These doors are shifted to closed position by mechanism substantially similar to that described in connection with the construction shown in Figs. 2, 5, and 6. The doors 6 are provided with arms 21, rigidly secured at right angles to the doors and have their upper ends pivotally connected to the sides of the car in such manner that their doors are in a horizontal or approximately horizontal position when closed. The doors 5 and 6 are connected so as to move simultaneously by means of arms 15, rigidly secured to one door, and links 16 connecting said arm with the other door, as described in connection with the constructions shown in Figs. 1 to 6. This manner of connecting the doors 1'. e., by a rigid arm and loose link-avoids arranged to support the floors adjacent to the hopper, and doors hinged to the channel-bars to swing laterally of the car,'and mechanism for operating said doors simultaneously, substantially as set forth.

2. A hopper-car having in combination, floors inclined from the ends toward the center of the car, longitudinal sills consisting of channel-bars forming supports for the floors intermediate of the sides of the car, a ridge supported by the channel-bars, transverse ridges extending from the channel-bars to the sides of the car, discharge hoppers or openings located on opposite sides of the longitudinal. ridge, doors pivoted to the car so as to swing laterally of the same and mechanism arranged along the transverse ridges for simultaneously operating the doors, substantially as set forth.

3. A hopper-car having incombination floors inclined to the discharge openings or hoppers, doors pivotally mounted on opposite sides of the hoppers or openings so as to swing laterally of the car, mechanism for shifting the inner doors and arms rigidly secured to the inner door and loose connections from said arms to the outer doors, substantially as set forth.

4. A hopper-car having in combination floors inclined to the discharge opening or hopper, and doors pivotally mounted on opposite sides of the hopper, one of said doors having side and bottom portions arranged at an angle to each other, substantially as set forth.

5. A hopper-car having in combination, floors inclined to a center discharge opening or hopper, doors pivotally mounted on opposite sides of the hopper or opening so as to swing laterally of the car, mechanism for shifting one of said doors and arms rigidly secured to one door and loose connections from said arms to the other door, substantially as set forth.

6. A hopper-car having in combination, floors inclined to a center discharge opening or hopper, doors pivotally mounted on opposite sides of the hopper, said doors having side and bottom portions at an angle to each other and plates extending from the inclined floors down alongside of the ends of the doors, substantially as set forth.

In testimony whereof I have hereunto set my hand.

AXEL HEIDEN.
