CROSSBEARER FOR DUMP-CARS.

Specification of Letters Patent. Patented ltlay 23, 1911.v

Application led November 7, 1910. -Serial No. 591,028.

To all whom it may concern:

'l Be it known that I, CHARLES A. LIND- s'rRM, a citizen of the United States, residing-at N o. 188 Stratford avenue, Pittsburg, E. IE., in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Cross-Bearers for Dump-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, 1n

which like Characters refer to like parts, and,

in which- Figure 1 Ais a sectional elevation of so much of a car construction as is necessary to illustrate my invention. Fig. 2 is a plan view of a portion of the same; Fig. 3 is a sectional view on the line 3-8, Fig. l; Fig. 4 is an end elevation of the casting forming a part of the structure. Figs. 5, 6, and 7 are plan, side elevation and end elevation views respectively of the part designated by the reference character 14 in Fig. 1; Fig. 8 is a side elevation of a modified form of the structure; Fig. 9 is an end elevation of the structure shown in Fig. 8, Fig. 10 is a sec` tional view on line 4-4, Fig. 8, and Figs. 1l and 12 are plan and end elevations respectively of the part designated by the ref.

erence character 14 in Fig. 8.

The invention is especially adapted to that class of cars known as general service cars in which the bottom of the car is made up of a number of drop doors, and in which said doors are closed through .the medium of a movable shaft, connected to said doors in any suitable manner, and adapted to sup-l port said doors in closed position.

As pointed out in my prior United States Patent No. 903,488, issued November 10th, 1908, in the type of car above mentioned, Athe use of a casting as a connection between a car underframe beam and the side of the car is especially desirable, in that it enables the formation of a suitable guide slot for the bodily movable shaft and reinforced connecting iange all in one piece or casting.

Stated specifically my invention consists in making a suitable guide'slot for a bodily movable shaft, in such a manner that a portion of the lower bearing surface of the slot can be easily removed. When it is desired to remove the shaft for the purpose of repairor replacement, the removable portion endwise through the slotsin .the castings.-

Vitli the use of my invention the shaft with all its accessories may be dropped bodily after the withdrawal of the removable portions of the slot castings.

With the foregoing advantages in view, the following detailed description will be more fully appreciated.

Referring now in detail to the drawings, `1 represents a section of half of the center sill structure, 2 an underframe beam or transom, 3 the car side and 4 a'car side stake.

5 is a casting forming the connecting medium between the car side 3 and stake 4 and the beam or transom 2. Casting 5 is here shown as provided with a slot 6 designed to receive and guide the movementof the shaft 23, shown in my United States Patent No. 791,348, issued May 30th, 1905, and entitled Car door mechanism. this patent this slot was formed in members which were riveted to the sides 7 of the beams or transoms so as to register approxi; mately with slots in said beams. In the present case the beam or cross bearer 2, is cut olf at a point 24, some distance from the side stake, so that the slot 6 in the casting 5 is unobstructed.l Casting 5 is provided with a flange 7, to which is riveted or secured the upper flange of the beam or transom 2. Casting 5 is likewise provided with a flange t), to which is riveted or secured the lower flange l0 of the beam or transom 2. Oppositely extending flanges 11 are also provided in the casting 5, which are adapted to be riveted to the stake 4 as shown in Fig. 1, and the car side sheet is brought down, bent inwardly at an incline and then outwardly, and riveted to fla1ige`71'. IF lange Tief cast- -ing 5 is shown depressed and at a lower level than the portion of the flange designated 7, to forni a seat for the flange 8, so

' Lio lili constructed in such a way that the upper surface of flange 8 is brought in 'the saine pla-ne with the upper surface of the forward portion ot the liar-.ges Ta, formi ing a fiat seat for the end portion et' the tie plate The llangee 7a also form a seat -Sor tbe outwardly bent portion of the side plate i5 to which it is secured.,v

in the lower portion oi the casting 5, an openbk i3 is provided, oit grez1 ter length in di tion oi' the length. o."A the slot than the diameter oit the door operating shaft. ln this opening is inserted, ondeecnred in an removable manner, a. bloelr or illing l -e the top surface l5 of said block or "-.ing piece. being the saine plane as the 1 portion the slot 5. piece member lll proiections 16 which rest in recesses formed to receive them. in casting 5, and so prevent-said member from dropping ont of its position.. rfhis member is further seemed in normal position by Cotter pins 17 which pass through perforations i8 and 19, in the flanges v respectiveiy. or filling piece f.. ,l no,

" e block or til d with. pi

rthe bottoni end o the block le, is' provided with flanges l formed in such a manner to engage with arojections 2l, on the lower flange ot cast-ing 5, so to compensate for any reduction in strength of casting 5, due to the opentor-ined therein.

it will be readily seen that in order to reni-ove the door operating shaft from tbe guide slots 6, all that it is necessary to do, is to remove the eotter pins l?, and slide ,filling piece sidewise out oli the opening 3.3, when the sha-ft may be lowered below the plane of the lower edge of the member 5, and removed from the car.

Cars of the class referred to are generally 'that veach door near serves to operate simultaneously the dump doors in one half of one side of the idoer of the car, so that the ends ofi the door operating shafts are in close'proxiinity to each other at the middle oil' the car. To prevent the of one of such shaits from coming in contact with 'the ond oit the other shaft, and so interfering with each other, a modiication of casting 5 is shown in Figs. 8, 9 10, .of the drawings. 'in this modilication, the slot for guiding the ends el? the sinn-Et is made of a width double that shown in Figs. l fi inclusive, and a wall or partition. is 'formed integral with the member 5, in the center of the widtb, oi" slot, so as to prevent the Iends of the sliait shown in dotted lines in li1 ig. if?, l." guided l" slots, 'From coming 'n con iet with he opening siot 6, as also the n 'l `igs. 8, 9 ,and l0, formed in the same manner as tiet shown iiLTigs. l. to fi inclusive. A. space between the lower e/lffe oi the partition wall 32-, tie top of oi said member and casting 5y l l l l l l l eeaoee provided, `to facilitate removal of the latter, by not allowing them to come in contact with each other.

"Silit-hin the scope of my invention as defined in the claims, the construction of the parts may be modified in many ways by the skilled mechanic, it is also obvious that my invention is susceptible of application, in car nnderirames in which the slots in the cross bearers extend nearly to the center line of the car, since v v i l.
