(01. 105_2v0) This invention relates to apparatus for the on a' railway truck E5. The vtrunnion l2 and’ transportation of molten materials, and more bearing l3 are formed with spherical bearing sur particularly to vehicles for transporting molten faces, separated by a bushing it of anti-fric tion metal (Fig. 3). It will be understood that iron and steel, known as hot metal cars. 5“ Apparatus of this type is well-known and has the opposite end of the container is tiltably sup heretofore been used in and around steel mills ported, in a similar manner, upon another truck, for transporting molten iron and steel from the which it is unnecessary to illustrate. It will also furnaces. to more or less distant points at which be appreciated that, if desired, the parts might the molten metal is to be cast or otherwise used. be reversed, the container being provided with bearings adapted to receive trunnions mounted 10V 1G: One type of vehicle so employed comprises a con tainer for the molten metal supported by means on the railway trucks. For the purpose of tilting the container ID to of trunnions, at either end, in bearings mounted on railway trucks. In such vehicles the con tainers are tiltable for the purpose of discharging ll: their contents, tilting being e?ected by external means, such as a crane operated hook, or by means carried on the vehicle, such as an electric motor mounted on one of the trucks and con nected, through suitable gearing, to the con tainer. 20 The present invention relates to vehicles of the latter type, and has for an object the provision of a suitable driving connection between the electric motor or other source of power and the con tainer, such means being employed that the con 2GI tainer may be tilted even though it be out of alignment with the power shaft, due to inequali ties in the track, sagging of thecontainer, per manent misalignment of the parts, or for any 301 other reason. A further object is the provision of a driving connection for the described purpose, which will not be injured by misalignment of the shaft and the container, occurring by reason of the vehicle passing around curves or over ine qualities in the track, or through other causes. These and other objects, features and advantages will appear from the description which fol lows, together with the accompanying drawing, discharge its contents a suitable source of power, such as a reversible electric motor I1, is provided. The motor I‘! is connected by suitable reduction gearing, indicated in Fig. 1, to a shaft l8, through Which rotary motion is transmitted to the con- ‘ tainer ill by means now to be described. The shaft i8 is journalled in bearings 21 and 23, car ried by the gear casing 29, and is permitted sub- 8 stantially no end play. As Will be best seen in Figs. 3 and 4, the trun nion I2 is provided with a recess l9, rectangular in cross-section, the upper and lower surfaces of which are provided with liners Z0 andv 2| of anti friction metal.* A hollow block 22,- rectangular in cross-section,‘ is mounted'within'the recess I9, ?tting snugly between the anti-friction liners 20 and Eli. It will be perceived that the transverse dimension of the block 22 is considerably less than that of the recess l9, thus permitting the block '22 a certain amount of horizontal planar movement, both linear and angular, within the recess l9. It will be understood that the term “planar movement” refers to linear or angular 35 movement in which each element of the moving member moves in a single plane, all of such planes being parallel. . _ ' ' The end of the shaft l8, modi?ed to a rectan in which Fig. 1 is a side elevation of one end of a vehicle of the type to which the present invention is adapted; gular cross-section, extends into, and preferably entirely through, the central aperture in the block 22, ?tting snugly between the vertical walls Fig. 2 is an end view of the vehicle of Fig. 1; Fig. 3 is an enlarged longitudinal vertical sec 23 and 24 thereof. The shaft l8 and block 22 are secured together by means of pins 25, 25’ which 45 tion through the container supporting bearing are threaded into the walls 23 and 24 of the block and driving connection, on line 3—3 of Fig. 4; Fig. 4 is a vertical transverse section on line 4-4 of Fig. 3; and _ Fig. 5 is a horizontal section‘ on line 5—5 of 50 Fig. 3. Referring to Fig. 1, a container It, provided with a suitable charging and discharging opening II, is provided at one end with a trunnion I2 which is supported in a bearing I3, the latter 65 being carried by a suitable pedestal l4 mounted 22, and extend inwardly into engagement with vertically elongated slots 26, 26' formed in the vertical surfaces of the shaft 18. The latter hav ing a vertical dimension somewhat less than that of the central aperture of the block 22, is per 50 mitted a certain amount of vertical planar move-7 ment, both linear and angular, within the block. A lubricant chamber 35! is provided between the’ gear casing 29 and the bearing l3, and communi cates with the recess H3. The chamber 30 is 55 2 2,115,213 7 adapted to be supplied with a suitable quantity of wheeled trucks, bearings carried by said trucks, of lubricant, and to act as a reservoir supplying lubricant to the bearings l3 and 28, and’ to the said trunnions having a central recess, a hollow members within the recess I9. member mounted within said recess for rotational , I . Since the block 22 is secured to the shaft l8, which latter is supported without substantial end play, there will be no substantial longitudinal movement of the block 22 and shaft ,l8 with respect to the trunnion l2. However, since the 10 block 22 is permitted a limited transverse move ment within the recess l9, and the shaft l8 may have a limited vertical movement within the block 22, it is apparent that the driving connec tion thus formed between the shaft I8 and the 15 trunnion 12, will be‘operative despite such mis alignment of the shaft and container as is likely to occur in service, and will not be injured by such misalignment. . Due to the inherently rugged nature of the 20 elements making up the drivingconnection of the present invention, it is particularly well adapt ed to transmit the considerable torque necessary for tilting the heavy container ?lled with molten metal, and to withstand injury. 25 The terms and expressions employed in the, foregoing speci?cation are‘ terms of description and not of limitation, and it is recognized that many variations of the described mechanism may be made without departing from the scope of the present invention. For example, the recess l9, ~ block 22 and shaft 18 need not-be rectangular, so long as the outer'surfaces of the block 22 are complementary to the inner surfaces of recess I9 and the inner surfaces of block 22 are comple 35 mentary to the adjacent surfaces of theshaft l8, and so long as each member has two opposite a container trunnioned in said bearings, one of ' ~ and translational transverse movement therein, 5 a shaft extending‘into said hollow member and adapted for rotational and translational vertical movement therein, said trunnion, hollow member. and shaft being incapable of substantial relative rotation about the axis of said shaft, and means for rotating said shaft. 10v , 3.
