To all whom t ma concern.'

` Be it known t at I, CHARLESv A.` LIND- i tion, of which-,the following is a full, clear,

and exact description of the same, reference bein had to the accompanying drawlngs,

` in w ich like characters refer to like parts,

and in which-,-

Figure 1 1s.a plan view of substantially l one-half of -a general car embodyingmy involition. Fig. 2 is a transverse section of the car, the left-hand half of the figure being taken on the line A-A ofFig. 1, and

' the right-handhalf on line B-B of Fig. 1.

Figs. 3, 4 and 5 inclusive are side elevations of intermediate portions of the side of the car, and Figs.' 6, 7 and 8 inclusive are sections on line C-C of Figs. 3, 4 and 5 respectively. Figs. 9 and .10 arey side elevations of the end portions of the side of the car-and Figs. 11 and 12 are sectionson. line zontal section on line E--E of Fig. 10, and

FigsQli and 15' are horizontal'sections on line F-F of Figs. 4f and 5 respectively. Fig. 16 isan end elevation of the car, and

Figs. 17 and 1-8 are horizontaly sectionsshowing modifications in the form and construction of the side stakes.

My invention relates to car construction and vmechanism especially adapted for carrying ordinary freight, as well as for ladings` which it may be desirable todump through n the' bottom of the car, when standing on trestles or on the usual level track; though `of car doors and operating mechanism.

it is adaptable for use with any suitable type An object of the present invention is to provide`- a simple, strong and economical construction of car, especially.v adapted for that class of freight cars having dro bottoms and known in the trade as genera service cars, but which may also be applied to gondola and other freight cars without drop otto-ms. l

Another object of the'present invention is to provide a car having a stronger side construction than has hitherto been possible,

which object is attained by the novel form Specification o1 Letters Patent.

i 'of side stake employed, having` its greatest cross section at the portion which is sub- ]ected to the greatest bending moment, namely, its lower lend portion.

l -Another object of this invention is to construct the side stakes of such a form that the lower=portions thereor'l will constitute substantial supports for the inclined load carry- .l ing floor plates, which. rest upon and are secured thereto, and forma protection to the l door winding shaft against damage from the lading while being discharged.

.Another object of this invention is to ellminate the inside gusset plates, which .have `hitherto been necessary to give the sides of the car the necessary amount of lateral stiiness to resist .the thrust of the lading, which object is also attained by the novel form of side stake heretofore referred to, and resulting in ay car which has no internal obstructions in the form of gusset plates to interfere with the lading.

Another object of this invention is to utilize what has, in cars-constructed hitherto, been left asa vacant space, formed by the side stakes, the inclined load carrying licor lates and the end portions of the'transoms, ut which in my construction is partly occu. pied by the lower widened portion of the novel form of side stake herein described.

Another objectof this invention is to supportthe door winding and locking shaft in ,the lower portion of they side stakes,-thus obviating any perfo-ration `or cutting away ofportions of the transoms, `with its result- ,A ant weakening effect.

Another object of this invention is to construct a car which in the event of its sides paired by removing and replacing where necessary, the'side stakes and sides, Without interfering with the transoms, which in cars at present constructed extend to and are secured to the sides of the car, and' which in the event of'damage to the side of the car, are usually also damaged and require to be either vreplaced or removed for repairs, necessitating an almost complete dismantling of the car underfram'e.

A furtherobject of this invention is to support the door winding and lockingshaft f in such a manner that 1t can be easily removed from its supports in a downward direction, by supporting it in openings provided in the lower portion of `the side stakes, thus avoidingthe making of such openings in the ends of the transoms, as has been customar heretofore.

A filrther object of this invention is to p'ovide certain modifications of the hereinfore described structures.

More specifically stated my invention relates to that class of car and dooroperatingand latching mechanism which is illustrated, described and claimed in United States Letters Patent No. 791,348, granted May 30th,

1905 to myself and John' F. Streib and United States Letters Patent No. 833,402, granted October 16th. 1906 to me. In the mechanism of both of these patents, chain means is employed for raising the doors, and a creeping shaft is emplo ed for first winding said chain means an then latching the doors in raised position directly on the shaft and not through the medium of the chain means, to relieve the chain means from load strains. It is however to be understood that l my invention may be applied to bottom dump cars' haying door operating mechanism of other* types than that above referred to, and which are provided with door operating shafts extending longitudinally of the car and at or near the vertical plane of the car sides.

Referring now in detail to the drawings, l indicates the center sill of the car which may be of any suitable form. such as box girder or I beam, but preferably of the modified A-shape illustrated in Fig. '2 of the drawings. This form of center sill is fully illustrated, described and claimed in United States Letters Patent No. 833,402, granted to me October 16th, 1906, and hence it is unnecessary to describe it 1n further detail in this specification. A

2 indicates the body, bolster which may also be constructed of any. referred form, but which is illustrated in t e drawings as being constructed in two sections, of plates and angle irons and secured at its inner end to the center sill. The outer ends 3 of these bolster members do not extend, as has been the usual practice, to the vertical plane of the side of the car, nor are they secured thereto, but terminate some distance therefrom. `These bolster members are furnished ,with the usual top tie plate 4 extending l length substantially equal to thel length of the bolster members, that is to say, they do not extend from the center sills to' which `of the bolster members.

they are secured, to the vertical plane of the car side, but are stopped short at a suitable distance therefrom. These Atransoms are providedwith top flanges 9, end flanges 10 which are secured `to the center sill, bottom flanges 11 which are deflected downwardly to prevent the discharging lading from lodging thereon, and outer end flanges 12 to which the lower end portions of the side stakes are secured. These transoms may also be provided with brackets 13 of triangular or other suitable shape which are sesured to the lower flanges of the transoms and to the lower portions of the center sill, and which serve to brace and strengthen the connections of the transom to the center sill.

14 indicates the novel form of side stakes with which the car is furnished and which are preferably formed of plates pressed into the' form of a Z, having a varying cro section from end to end and a lower end portion adapted to be secured to the ends of the transoms. The side stakes 14 which are secured to the holsters as well as those secured to the transoms adjacent to the bolsters are of similar construction to the other y side stakes, but are provided with an additional angle bar reinforcing member 15, which Ais secured to the stake, to the sides and sloping floor of the car, and to the ends These stakesA are all constructed in such a form as to provide an inwardly sloping portion 1.6 and an, end portion 17 of greatly increased horizontal depth as compared vwith the upper portion 18, thus providing greatly increased strength in the side stake at the point where the bending moment is greatest due to the sidewisefhrust of the lading. i

19 indicates the side wall of the car, the upper portion 20 of which is substantially vertical. the lower portion 21 sloping in'- wardly and downwardly and forming an inclined load carrying floor plate. The lower portion 22 is also bent outwardlyY toward the side of the car forming a longitudinal edge plate, which is notched or cut away to permit the lower portion of the side stakes' to pass therethrough. 'l The top tie platemember 4 of the bolster, which as previously stated extends across the center sill of the car, also extends to and has it! outer ends 23, 9.3 bent upwardl in such av manner as to contact with the lower portions of the inclined load carrying floor plates 21 and said ends are secu red thereto. The upper tie plate members A of the transoms 8 do not extend continuously across the center sillvbut their nnerends lap under the-top flange 25 of the T-shaped upper member 26 of the center sill, and are secured thereto. The outer ends 27 of these tie plate members extend to the inclined load carrying floor plates 21, and have their ends inclined upwardly to contact therewith and are semembers and transoms adjacent tothe doors f to prevent the dropping of the doors more than a predetermined distance. l4oy thereto, and in which slots 31 are formed.

to permit of the application and support of the door winding and latching shaft 32, but as this mechanism is fullyfillustrated, de-

scribed and claimed in United States Letters Patent No. 7 91,348, granted May 30th, 1905, to myself and John F. Streib, further description of the same is herein considered unnecessary. The castings 30 are provided with openings 33 in their lower portions to permit of the removal of the shaft 32 for the purpose of repair or replacement, -the openings 33 in the castings 30 being furnished with a removable member 34 adapted to bev secured therein, the withdrawal of which permits the shaft with all its accessories to be lowered bodily from its normal position inthe slot 31 in the casting 30. However, as

this feature is fully illustrated, -described and claimed in United States Letters Patent No. 993,082, granted to me May 23rd, 1911, further description of the same is herein consideredv unnecessary. I

The drop doors 35 are hinged to the center sill in the usual manner. and the bolster are provided with suitable stop ymembers 36 Fig. 1 7 shows'a modification of the construction of the side stake of the car, in

`which the body member of the'stake is formed of a steel plate pressed into channel form of varying section and reinforced by an angle bar riveted to the back of the inner edge of the stake member. Fig'.v 18 illus-y trates a further modified form of the con-` struction of the `side stake of the car, in which the stake is formed `of a steel plate pressed into channel form of varying cross section.
