RAILWAY-CAR.

SPECIFICATION forming part of Letters Patent N0. 780,765, dated January 24, 1905.

Application filed August 29, 190 3- Renewed December 24:, 1904. Serial No. 238,226. I

To all whom" it may concern:

Be it known that I, SPENCER OTIS, ,a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, am the inventor of certain new and useful Improvements in Railway-Cars, of which the following is a specification.

My invention relates to that class of cars known as freight-cars.

It relates, further, to that class of freightcars known as dump-cars having dumpingbottom portions arranged on opposite sides of the longitudinal center of the car, and having transverse or deck beams arranged transversely of the car, and having upper inclined surfaces extending outward laterally and downward at an incline.

It relates, further, and particularly, to such acar having deck-beams provided with flanges forming inclined upper surfaces extending outward laterally and downward at an incline from the center, such flanges forming shoulders adapted to engage the ends of the clumping-bottom portions and having suitable means for operating such dumping-bottom portions.

The principal object of my invention is to provide a simple, economical, and efiicient railway-car.

A further object of the invention is to provide a dump-car having a plurality of dumping-bottom swinging sections and-provided with suitable deck-beams mounted upon the longitudinal beams or sills and extending transversely of the car, each of such deckbeams having inclined flanges adapted to engage the ends of such swinging sections, such car being provided with suitable means for operating such swinging sections and holding them in closed position, whereby the contents of the car over the deck-beams may be discharged from the deck-beams and a tight joint formed between such deck-beams and the dumping-bottom sections.

Other and further objects of the invention will appear from an examination of the drawings and the following description and claims.

The invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation of a car constructed in accordance with my improvements; Fig. 2, a broken plan view of a portion thereof, and Fig. 3, a sectional elevation, taken on line 3 of Fig. 1, showing the dumping doors or swinging dumping-bottom sections in their lowered position.

In the art to which this invention relates it is well known that it is very desirable to provide a dump-car having a bottom portion comprisinga longitudinal central portion and having a plurality of swinging sections forming the dumping-bottom portions arranged on each side of such central bottom portion and having longitudinal center sills, deck-beams, and bolster mechanisms so arranged with relation to each other and of such form as to provide the necessary amount of clumping-space. It is also desirable that the rigid portions of the bottom of the car he so arranged as to permit all or the greatest possible amount of the material handled to be dumped without manual labor; also, to provide suitable means for operating the swinging sections which form the dumping-bottom portion and for holding such sections in closed position, so as to form a tight connection between such swinging sections and the deck-beams.

In constructing a car in accordance with my improvements and in order to accomplish these purposes I provide a supporting-frame portion composed of longitudinal sills a, centrally disposed and extending from end to end of the car. End sills b are mounted upon the upper sides of these longitudinal sills and flush with the opposite ends thereof. A plurality of deck-beams c are provided and laid upon these longitudinal sills extending transversely entirely across the car, and upon the bottom frame thus provided is mounted suitable side frames 0?, comprising side sills c and suitable end frames f, which may be of any ordinary and well-known type, all together forming the frame or box portion of the car.

To provide a suitable body-bolster mechanism to be used in lieu of the ordinary bodybolsters known to the art and in order to provide means whereby such ordinary bolsters transversely arranged across and laid upon the upper surface of the longitudinal sills already described and extending downward at .each end over the outer edges of the sills, and

a lower bar it, which extends transversely across and beneath the under surfaces of the longitudinal sills and which is provided at its opposite ends with side bearings 2' upon the opposite sides of the center sills. From the extreme outer ends this bar extends upward and backward, preferably at an incline, until it meets the center sills and is connected thereto and to the downturned ends of the upper bar by means of bolts 7', the opposite ends of such bar being provided at the inclined portions 70 with integral web portions Z, forming shoulders m, which, together with upwardly-extending shoulder portions n, form suitable sockets for holding the center sills and metallic portions of such bolsters or bars firmly in position with relation to each other. This lower bar is also provided with a suitable center bearing 0, the use of which is well known and needs no further description here. It will be seen from an inspection of Fig. 1 that this bolster is arranged midway between the deck-beams and end sills and that there is no deck-beam or other rigid element extending outward transversely of the car immediately over such bolster to interfere with the action of the swinging sections of the dumping-bottom portion or to necessitate the shortbottom, as shown at the left of Fig. 3.

ening of the swinging sections to provide space for deck-beams over such bolsters.

A plurality of swinging dumping-bottom sections 10 are pivotally connected to the framework of the car at each side of the longitudinal center thereof by means of hinges q, so that they may be dropped down over the ends of the bolsters above described and between the deck-beams to form inclined dischargingaprons, as shown at the right of Fig. 3, or raised and held in position to form a closed These swinging dumping-bottom sections are of sufficent width to extend outward laterally of the car beyond the side frames, as shown, so as to "combine with the advantage of a wide discharge-opening and low inclined dumping portion the further advantage of discharging the contents at a great distance laterally of the car without raising the door so as to diminish the pitch of the incline, and these dumpingsections are of such length as to extend from the deck-beam to the other and entirely over "lifi' bolsters. By this arrangement it will be readily seen that no joint is necessary over the bolster and that the swinging sections maybe of any desired length, limited only by the distance between the deck-beams or between the end sill and the next adjacent deck-beam.

In order to provide suitable means for raisoperating-rods is provided with preferably a plurality of lever-arms w, the swinging ends of which are connected with the outer edges of the swinging bottom portions by means of links y, one end of which is pivotally connected to the lever and the opposite end of which is pivotally connected to the swinging-bottom section by means of an eyebolt 2. A ratchetwheel 3 and operating-lever 3 are mounted upon each of such operating-rods, and a suitable pawl 4 is mounted in the end frame of the car in operative engagement with such ratchetwheel to hold the operating-rods, with their links and lever mechanisms, against rotation, and thereby securely hold the dumping-bottom section in closed position when desired and permit it to be opened by rotating such operating-rods when desired. The links which connect the dumping-doors or swinging dumpingbottom sections with the lever-arms are bent inward at their upper ends, as at 5, so as to permit the levers to pass over and beyond the center of the operating-rod when in their raised position, and thus form a locking connection between the levers and doors when they are in their raised position. By this arrangement the swinging sections are when in their raised position substantially iiush with the upper edge of the deck-beams and in operation swing downward between the deck-beams into dumping position. It is very desirable to form a tight connection between the ends of these dumping-doors or swinging sections and the deck-beams and to provide the deck-beams with means whereby all of the material which would otherwise lodge thereon may be discharged when the dumping-doors or swinging sections are lowered. Each of the deck-beams is therefore made, preferably, of metal and is composed of a central web or body portion provided at its lower edge with integral flanges 5, extending substantially at right angles to the web portion. Each deck-beam is also provided at its upper edge with integral flanges 6, which extend outward laterally and downward at an incline from the center of the upper surface of such deck-beam beyond the edge of the lower flanged portions already described and into engagement with the ends of the swinging sections or dumping-doors. These upper inclined flanged portions thus form an A-shaped upper inclined surface for the deck-beam which is adapted to discharge all material which might otherwise restthereon, and the flanges form a tight connection between such deck-beams and the ends of the dumping-doors. The lower flanges being narrower than the upper flanges of the deck-beams permit the doors to swing down past such lower flanges and upward into raised position and into tight engagement with the wider upper flanges, as shown in Fig. 1. The lower flanges may be made of any desired width at the points where they rest over the center sills and also on the outside of the swinging sections; but where the swingingbottom sections have to pass such flanges they should be made narrower than the upper flanges, as above described.

To permit material which would otherwise remain upon the central longitudinal bottom portion of the car to be automatically discharged when the swinging sections are lowered, an A-shaped bottom portion 7 extends downward and outward at an incline from the longitudinal center of the car over the center sills and to the floor-level at the point where the swinging sections are hinged to the car-frame when the swinging doors are lowered. The A-shaped central portion and such swinging doors thus form a continuous incline adapted to discharge the entire contents of the car, or at least all of such con tents as may have been immediately over such parts, and the A-shaped upper edges of the deck-beams discharge all of the contents of the car which might otherwise remain upon such deck-beams, and at the same time the inclined upper flanges form a tight connection with the swinging sections when in their raised position. The deck-beams thus formed have great rigidity and strength and occupy the minimum of space between the ends of the swinging sections.
