CONVERTIBLE-TYPE DUMP-CAR.

:Specification of Letters Patent.

Patented Oct. 24, 1916.

To all 'Lo/0m t may concern:

Be it known that I, Ancriin CAMPBELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Convertible-Type Dump-Cars, of which the following is a full, clear, concise, and eXact description, reference being had to the accompanying drawings, forming al part of this speciication.

rIhis invention ielates to improvements in convertible type dump oar.

An object of the invention is to provide a car which may be used either as a gondola, side dump or center dump-car.

Another object of the invention is to provide a car of the type above indicated which is so arranged that it will resist the buffing shocks and has a center sill in addition to load carrying intermediate sills.

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices, 'as herein shown, described or claimed.

In the drawing forming a part of this specification, Figure 1 is a side elevation of substantially half a car showing my iinproveinents embodied therein. l Fig. 2 1s a top plan view of the car illustrated in Fig. 1 and is broken substantially at the center of the car and Fig. 3 vis an enlarged detail transverse sectional view taken substantially on the line 3-3 of Fig. 2, the left hand portion of Fig. 3 showing the parts when the car is arranged either for service as a gondolaor for side dumping and the right hand portion showing the parts positioned when the car is being utilized as a center dump car.

In said drawing, 10-10 denote the wooden side walls of the car, 11 the end sill, 12-12 the vertical side stakes, 13-13 the side sills which, as shown, are in the form of channels disposed above the floor level of the car, 14-14 the load carrying intermediate longitudinal sills and 15 thegenter sill.

As shown, each intermediate longitudinal sill 14 comprises a vertical plate 16 having angles 17 -17 secured to the top thereof and angles 18--18 secured to the bottom. The center sill, as shown, comprises an I-beam reinforced by angles 19`19, said angles also serving another pointed out.

As will be understood by those skilled in the art, both the intermediate sills and the center sill may be constructed otherwise than as I have shown, although I consider the forms illustrated as preferable. Between each intermediate sill and the side stakes are diaphragm plates 20 and between each intermediate sill and the center sill are diaphiagin plates 21-21, it being understood that said plates are suitably flanged to permit riveting to the sills and side stakes. The end floor of the car, as shown.y is made permanent as indicated by the Hoor boards 22. Intermediate the permanent end Hoor portions of the car, and over what is commonly designated the hopper section of the car between the trucks, the Hoor of the. car comprises sets of hinged floor doors 23 and side dumping hinged floor doors 24. The

function as hereinafter floor doors 23 are provided with hinge strapsv 25 mounted on hinge pins 26 and the side dumping doors 24 are provided on their inner edges with Corresponding hinge straps 27 mounted on the same hinge pins 26.

When the car is used for gondola service,

the hinge floor doors 23 have their free or inner edges resting upon the center sill 15 and the doors 24 are held up in horizontal position by suitable door operating mechanism, such for instance, as the chains 28 wound over longitudinally extending operating shafts 29 suitably mounted in bearings formed in the side stakes and other bearings 30 located at the ends thereof. The operating shafts 29 are squared at their ends whereby the same may be operated by a claw bar or other suitable device and in order to lock the saine, each shaft is provided with latch wheels 31 and latches 32 coperable therewith. For side dumping, the floor doors 23 are left in the position shown in the left hand portion of Fig. 3 and the hinge doors 24 are lowered as indicated by the dotted lines on the left hand portion of Fig. 3.

When the car is utilized for center dumping, the doors 23 are swung up to the position indicated on the right hand portion of Fig. 3 at 23A, the upper edges of the doors 23 resting against the side walls 10 of the car. The center dump hinge doors 33 are hinged at their upper edges by hinge straps 34 to hinge butts 35 secured to the center sill lbeneath the angleirons 19. *'Each door 33 has strengthening angle irons 36 at its ends and said doorsA are operated by means of chains 37 connected 'at one end to brackets 38 secured to the doors .33, said chains winding over longitudinally extending operating lshafts 39 mounted beneath the intermediate sills 14. The shafts'39 are suitably mounted in brackets yandA are squared at their ends and provided with latch wheels and latches as indicated at 40 whereby the same are operatedand locked in the usualmanner. Secured to the inner side of each intermediate sill 14, near the bottom thereof, and extending between each pair of diaphragms 21, are inclined diverting boards 41, the latter being bolted or otherwise suitably secured to brackets or braces 42 which in turn are riveted to the intermediate sills and angles 18. These diverting boards serve to divert the material to points between the tracks, when the car is being utilized as a center dump car, it being understood that the rails arelocated directly beneath the intermediate sills 14. Each of the center dump doors 33 is provided along its upper edge with a flange 43 which serves to cover the hinges and in conjunction with they angles 19 prevents material from falling between the angles and the doors 33. As shown in Fig. 2, when the car is vbeing' used as either a side or center 'dump car, temporary ends may be formed at the ends of the hopper section'by boards 44 which are removably held between angles 4:3 45 secured to the inner faces loit' the car sides. lVhen the boards 44 are not being used, they may be stored by placing the same between the ends 11 of the car and angles 46-46 (see Fig. 2).

From the preceding description it will be seen that I have provided a car of the convertible-type which is of strong construction, which may be readily changed from either side to center dumping, or vice versa, and wherein a center sill construction is employed in addition to the intermediate sills which center sill not only absorbs the buiiing shocks in direct line with the draft rigging but is also of value on account of its vertical strength. l

As will be understood by those skilled in the art, various changes may be made in the details of construction and arrangement of parts, particularly the various door operating mechanisms and constructions of the sills.

rlhe form which I have shown and described I consider the preferable one but contemplate all changes and modifications coming within the scope of the claims appended hereto.

I claim 1. In a car of the character described, the combination with a car body having intermediate sills with hoppers formed therebetween, and a center sill adapted to absorb bufling shocks in direct line with the draft rigging and having also a vertical strength value, of pivoted floor doors, some of said doors being adapted to cover said hoppers between the intermediate sills and being partly supported by said center sill when acting as iioor members, and others of said floor doors being adapted to dump to the sides of the car.
