CONVERTIBLE DUMP-CAR.

SPECIFICATION forming part of Letters Patent No. 674,087, dated May 14, 1901. Application iiled February 4, 1901. Serial No. 45,939. LNo model.)

To all whom, t may concern:

Be it known that I, HARRY STILLsoN HART, a citizen of the United States, residing at Chicago, in the county of Cook andpState of Illinois, have invented certain new and useful Improvements in Convertible Dump-Cars, of which the following is a specification.

My invention relates to that class of cars which when arranged in one position may be 1o used for ballast-cars-t-hat is, a class of cars adapted to carry broken stone and similar material and dump it between the tracks in such a pile as not to overliow the tracks and which is adapted to be converted by the rearrangement of the parts into a second position to form a gondola car, all of which will more fully hereinafter appear.

The principal object of the invention is to provide a simple, economical, and eticient hopper or dump car which by the rearrangement of certain parts may be converted into a gondola car-that is, a car with a iiat bottom and vertical side and end portions.

A further object of the invention is to provide a dump-car with a hopper-bottom the apex of which is arranged longitudinally of the car and at or near the center thereof and with inclined sides made in two or more sections, one a stationary section forming the bottom of the hopper and the other a movable section pivotally secured to an immovable portion and adapted to be folded over to occupya horizontal plane and form the bottom of agondola car whenever desired and be returned to an inclined position and form a portion of the hopper-bottom when desired.

Further objects of the invention Will appear from an examination of the drawings and the lfollowing' description and claims.

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

In the accompanying drawings, Figure 1 is a plan view of a portion of a car constructed in accordance with these improvements, showing it as it appears when the parts are arranged in position to form a ballast-car; Fig. 2, a similar view of the car as it appears when the parts are arranged in position to form a gondola cara car having a flat bottom and vertical sides and ends; Fig. 3, a longitudinal sectional elevation taken on line 3 of Fig. 2 looking in the direction of the arrow; Fig. 4,

a cross-sectional elevation taken ou line 4 of Fig. 3 looking in the direction of the arrow, 55 and Fig. 5 a cross-sectional elevation taken on line 5 of Fig. 2 looking in the direction of the arrow.

In the art to which this invention relates it is well known that it is desirable to have a 6o hopper-car so constructed and arranged that it may be used as a ballast-car in summer or during such Weather as it is possible to ballast railroad-tracks and at other times to rearrange the elements of which the car is composed to'form a gondola car-that is, a car having a flat bottom and vertical side and end portions. There have, however, heretofore been many difficulties in the way of constructing a simple, economical, and efficient car for 7o this purpose, for the reason that the apex of the hopper of a ballast-car must meet in a line coincident with the longitudinal center of the car, and the inclined sides and bottom portion of the hopper must be arranged at such au angle that they discharge the ballast through one door at the bottom of the hopper and in a pile of such shape as not to throw any of the -ballasting material on the tracks. In building a car, therefore, to conform to these 8o prerequisites it has been found very difficult to make foldable forms and sections that could be economically and efficiently used for the purpose of converting it into a gondola car. The principal object, therefore, of my invention has been to make a car of this type which would overcome the above-noted diiiculties, obviate the objections incident thereto, and encompass all of the advantages desired in such type of cars.

In illustrating and describing my improvements I have only illustrated and described those portions or parts which I consider to be new, taken in connection with so much that is old as will properly disclose the invention 95 to others and enable those skilled in the art to practice the same, leaving out of consideration other and well-known elements, which if described herein would only tend to confusion, prolixity, and ambiguity.

In constructing a car in accordance with my improvements I make a supporting-frame IOO of the usual size and shape and provid ed with the usual side sills a, intermediate sillsv b, and end sills c, secured together in the usual manner. Of course it will be understood that this frame portion may be provided with the usual body-bolster arranged to be supported upon a truck in the usual manner, all of which will be understood by those skilled in the art and needs no further description or illustration here.

In order to furnish the necessary7 elements for a ballast-car, two inclined portions are provided which form the hopper sides, each of which is formed in two sections d and e, arranged longitudinally of the car, and the apex of which is arranged substantially coincident with the longitudinal center of the. car,

' as' shown clearly in Figs. l and 4. The car is also provided with inclined end portions triangular in contour and made in two sections, one an upper removable section f, secured to the inclined sides by means of bolts g, which are passed through angle-irons, in turn secured to and forming a portion of the inclined ends, and the other a lower sectionf, immovabl1 secured to the frame of the car, as shown particularly in Fig. 3. One of the inclined sides of the hopper portion, at the lower part thereof, is provided with a swinging door h, hinged to such side and to one of the bracing cross-beamst' by means of a hinge j, asshown particularly in Figs. 4 and 5. The inclined sides, which form the hopper of this ballast-car, are arranged at about an angle of fifty degrees from the horizontal,with the apex thereof the desired distance above the ground, so that when the swinging door is open the materialwill pass outth'rough such door and from this incline be impelled to a point between the tracks almost exactly central and form a pile of such shape and dimensions as not to overiiow the tracks, and thereby interfere with the running of the trains. The door is held closed by means' of a rock-shaft 7c, to which a chain l or equivalent mechanism is secured and which is also secured to the door, as shown in Figs. 4 and 5. The rock-shaft may be provided with any desired locking mechanism to prevent its rotating when the door is closed, such as a ratchet-wheel and pawl; but as such mechanism is well known to those skilled in the art and does not form any material part of the invention it is not deemed necessary to further describe it here.

It is extremely desirable for the purposes ofv economy that the car above described-be so arranged that it can be-u'sed as a ballastcar in the summer season and as a gondola car in the winter, when it vis usually practically impossible to `ballast tracks. To accom plish this result, immovable Hoor-sections w are provided and the inclined hopper-bottom is made i'n two sections, as above described, the lower section d' being practically rigid or immovable in theordinary sense of the word,

while the upper section is foldable, so that it can be laid in a fiat plane and'in connection with the immovable sections 0s complete the floor. The upper sections e are provided with angle-irons m, as shown in Figs. 1 and 4, the lower part of which is provided with an elongated slot n, engaging with a pin or hinged stud o on the lower part ofthe hopper-bottom. It will be noticed that these side hopper-sections are hinged together at or near the floorlevel (which has hitherto been deemed impossible) and retain the desired inclination of hopper sides. The upper ends of these angle-irons are secured to the angle-irons p on the car sides by means of links q. The inclined end portions of the hopper, as shown in Figs. l and 3, are also bolted to the hopper sides, so as to make such portions of the hopper side when in use practically immovable or rigid to stand the strains incident to its use as a ballast-car.

When it is desired to use the car as a gondola car, the bolts securing the inclined upper end and side portions of the hopper together are removed and such end portions placed at the end of the car in a vertical position, while the bolts g are passed through the Iianges which are secured to the llet r, thus securing the ends in a vertical position and providing for the ends of the gondola car. The removable center sill s, which is shown under one of the inclined sides in Fig. 4, is next placed in position in the longitudinal center of the car, as shown in Figs. 3 and 5, with its end portions resting in the recesses t. (Shown in Figs. l and V4.) The links q, which secure the upper edges of the upper side portions to the sides of the car, are next removed and the upper portion of the inclined sides folded over into a horizontal plane, as shown in Fig. 4, so as to complete the floor portion, the intermediate sills, in

connection with the removable center sill s,

being used to support such parts in position.

From the foregoing description of construction and operation it will be seen that the upper parts of the side portions are hinged or f'oldably secured to the lower part of the hopper at or near the floor-level, so that all that is necessary is to close them in very much the same way as a cellar-door is closed, while the slot in the hinges permits the foldable parts to-be held in. position and at the saine time provides for sufficient leeway to accommodate the diiferent positions which the foldable parts have to assume. The center sills and the intermediate sills a and b are slotted at v (see Fig. 2) to permit the angle-irons on the inclined sides to rest therein whileoccupying a [iat plane.

The principal advantages incident to a car constructed in accordance with my improvements are, rst, the car is very economical to construct, simple to understand, and efficient in operation; second, the lines of a ballastcar can be exactly followed, while the inclined portions may be secured together in a foldable manner, so as to permit'of easy convertibility, and, third, the parts are secured ICO together in a thorough and Workmanlike manner, all of which will be readily understood by those skilled in the art.
