HOPPER-BOTTOM CAR.

SPECIFICATION forming part of Letters Patent No. 763,706, dated June 28, 1904.

Application ma 13,1903. seriaino. 165,279. (No model.)

To all, whom nuty concern: Be it known that we, HERBERT WOLFE and ARTHUR LIrsOHU'rz, citizens of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Hopper-Bottom :Cars, of which the following is a full, clear, and exact description, suchas will enable others skilled in the art to which it appertains to make and use the IQ same, reference being had to the accompanying drawings, forming part of this specification, in which 3 Figure 1 is a side elevational view of one end of a hopper-car constructed according to 5 our invention. v Fig. 2 is a longitudinal sectional View of the same. Fig. 3 is a plan view partly in section, and Fig. 4 is an end view partly in section. This invention relates to new and usefulirh- QC provements in hopper-bottom carscontaining a plurality ofhopper-sections which are dividedat the center sills, the object being to construct such a car with plate-girder sides and of such general type of construction that 5 the car may be lengthened substantially on the same lines to any convenient length for the purpose of providing for greater or less capacity, as maybe desired.

In the drawings illustrating the invention, 3 1 representsplate-girder sides provided with the usual tension and compression members, comprising angles or other rolled shapes secured to the side plates-l along the top and bottom, in addition to which angles 2 2 and channels 3 and 3 are connected with said side plates at such convenient intervals thereupon as may be best adapted to serve the purposes desired for strengthening the several parts and providing a unitary structure of the 4 strength required. The underframing of this car includes continuous bolsters A, extending from side wall to side wall and secured thereto by means of brackets B and fillers G, the said fillers being substantially channel-shaped in cross-section with the middle portion thereof secured to the side walls 1 and the legs connected with the web portions of said bolsters A. End sills D are provided, which may be of any convenient type best adapted to serve the usual purpose of such end sill, and extending between the end'sills D and said bolsters Aare short draft-sills E, preferably of pressed steel or commercially-rolled channelshaped members, as shown. Between the bolstersextends either a single center sill or a plurality of center sill members F F, which members are preferably either commercially rolled or pressed channel shapes or built-up structures of the same general type as may be best adapted to serve the required purpose.

Extending substantially in the same plane with the center sills are transversely-extended girders 4, which in the present instance are represented as comprising cOmmercially-' rolled I-beams, which project to a plane above the upper plane of the center sill members, while the lower portion of thecross-girder and said sill members are in substantially the sameplane. Extendingverticallydownwardly from the angle 5 and secured to the plategirder sides in alinement with said cross-girders 4 are channel-shaped braces 3, which are I connected with said cross-girders at the ends of said girders, so as to form supports therefor of such construction that the weight of the structure and load supported by said girders will be distributed to the plate-girder sides.

In alinement with the bolsters A are other channel-shaped braces 3, connecting the side plates and said bolstersthrough the filler B of said bolster before referred to. The channels 3 3 may, if desired, each comprise a single commercially-rolled channel member or may consist of a plurality of angles, accordper-openings are shown, said hopper-openings being closed by the same number of doors 6. The general plan of the door-operatingmechanism is such that the tendency of the doors at all times is to drop by gravity away from the discharge-openings of the hopper-sections, and the chain, cable, or other lifting means 7 is essential to hold said doors in a closed position, said cable being wound on a drum on the shaft 8 and being connected with the loops 9, attached to said door 6. Connected with the doors 6, substantially centrally thereof, are links 10, which links extend upwardly in an oblique direction and are connected with the side hopper-sheets 11, the connection thereof to said sheet being such that when the link 10 is in avertical position the door 6 will swing below the hopper-opening, as best shown in Figs. 1 and 2 of the drawings. Connected also with said door 6 and said side hoppersheets are guide-links 10, also obliquely disposed, but more nearly perpendicular than the first-mentioned links 10. The object in so disposing the links 10 10 is to provide such connection for the door that when the winding cable or chain 7 is released the weight of the load thrown on said doors 6 will cause them to open and by reason of the angular adjustment of the said links will cause a tilting of said doors 6, as best shown in dotted lines in Fig. 2, whereby the load will be more perfectly discharged, after which the doors 6 may be closed by rewinding the cable 7. Connected with the web portion of said transverse girder or girders 4 are oppositely-disposed inclined floor-sections 12, which are provided with angles 13, adapted to form frames for said doors 6. Said inclined floorsections are provided with upwardly-disposed flanges 14 or other convenient means, whereby they are connected, respectively, with said hopper-sheets 11 and with the inner hoppersheets 11, the latter being connected with said center sills, as best shown in the sectional portion of Fig. 4. The said transverse girder 4, with the oppositely-inclined floor-sections 12, being connected with the said plate-girder sides are firmly supported thereby and form the usual transversely-extended ridge common to this class of cars. Suitably supported by the end sills are braces 15, connected, respectively, with said end sills and the end walls G of the car, and from said end walls Cr to the discharge-opening nearest thereto the end floor-sheets 16 project in an oblique line, said end floor-sheets being flanged upwardly at 16 and riveted to the side plates 1. Connected with said end braces 15, the channel-braces 18, and the center sill portions Fare angles 17, which extend parallel with said inclined end floor portion and serve as supporting means therefor. In addition to said angles 17 said channel-braces 18 extend upwardly from the cover-plate 19 of the bolster and serve as supports for said end floor portions, whereby said inclined end floors are securely supported.

It is obvious that struts of any form may be substituted for the channels 18 and angles 17 shown where desired.

As the hopper-sections are divided centrally by the center sills, a longitudinally-extending deflecting-crown 20 is provided, which extends in substantially the same plane from end to end thereof above said center sills, being provided with downwardly-extended legs 21, which are riveted to the said center sills.

or This deflecting-crown may be of any convenient shape in cross-section and may consist of a single sheet pressed into the desired shape or of a plurality of sheets riveted together, as may be desired, and it will be noted that the deflecting-crown extends to a plane sufficiently high to extend above the transversely-extended girders before described, the legs 21 of the crown being cut away where said girders extend therethrough, though the deflecting-crown and transverse girders may be in substantially the same plane where desired.

Between the sills door-supporting means are provided, which means may be duplicates of the levers 1O 10 or may comprise single yoke members 10 bifurcated at their lower ends, as shown in Fig. 4, said members or yokes 1O being supported by brackets or any other convenient means connected with the center sills, or where the links 10 10* are duplicated lugs may project inwardly from the center sills and said parts be supported therefrom.

With respect to the above construction it will be noticed that the side walls in the form of plate girders carry the cross-beam 1, which su pports a continuous end of the sections of the center sill. The inclined floor-sheets 12 form an interrupted cross-ridge, they being riveted to the cross-beam at their upper edge and to the inside and outside hoppersheets at their ends, thus leaving the space between the inside hoppersheets free for the door-operating mechanism.

We are aware that minor changes in the construction, arrangement, and combination of the several parts of our device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of the invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
