Application filed July 10,1900. Serial No. 23.075. (No model.)

To 1f/ZZ whom, t Wtrty concern:

Be it known that I, TIMOTHY LONG, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Car-Dumping Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of the invention is to provide a highly efficient apparatus for raising and tilt-V Fig. 4 is a rear elevation, partly in section,

of the cradle on which the car Ais supported. Fig. 5 is a plan view of said cradle. Fig. 6 is a plan view of the trestle-tower. Fig. 7 is an end view of the cradle,partly broken away. Fig. 8 is a transverse sectional end View of the cradle, partly broken away, the section being taken on the line 8 8 of Fig. 4. Fig. 9 is a transverse sectional end view of the cradle and the front part of the trestle-tower, showing in dotted lines the cradle in dumping position; and Fig. 10 is an end view of the beam which carries the chute and of a part of the cradle.

This apparatus, like previous apparatuses designed for a similar purpose, includes a trestle-tower A, which may be of any suitable construction. This tower consists of four corner-posts a a ct a and suitable beams, braces, &c., connecting them, so as to ina-ke astrong rigid structure. The two front posts ct ct, which are vertical, are not connected together directly except at their upper and lower ends, Wherefore the front of the tower is open to permit the apparatus to operate as described. Within the tower is a verticallymovable cradle B, capable of supporting a loaded car. The specific construction of this cradle is not material. It must have a strong horizontal portion, on, which the load is for most part supported, and a front side, which supports a considerable part of the weight of the car when the platform is tilted. As shown, the cradle consists of a plurality of L-shaped angle-iron ribs b, which extend horizontally across the cradle and substantially vertically at the front side thereof, and suitable longitudinally-extended beams b', which connect the ribs b. The door and front side of the cradle are preferably completed and closed by sheet-metal plates b2, as shown. Guiderollers b3 are mounted on the ends of the front side of the cradle near the top thereof, and these rollers enter and are guided by the vertical grooves (13 in the inner faces of the two front corner-posts a. Other guide-rollers b4 are mounted on the ends of the cradle at the lower front corner thereof, and these rollers ride against the rear faces of said cornerposts. These rollers serve to guide the front side of the cradle in its upward movement,but permit it to be tilted, as will be presently described. The cradle supports a rocking platform C, which is eccentrically pivoted to the cradle on longitudinal horizontal pivots c, which are secured to the ribs b. These pivots are below the platform and behind the vertical line of its center of gravity, wherefore the tendency of the platform is to tilt forward. When the cradle and platform are in position for the cars to run onto'the tracks T T, secured to channels c2 on the top of this tilting platform, the said platform C (or rather transverse ribs c3 on the under side thereof) rest upon fixed transverse beams J J', which are secured to parts .I .I of the foundation of the tower, whereby said platform is held in a substantially horizontal position, or at least is prevented from tilting forward, as it would otherwise do because of the non-central position of the pivoting-shaft.

A vertically-adjustable chute E is located on the front side of the tower, and into this the load of the car is dumped. This chute delivers the load into the hatchways of a boat or into any other receptacle provided to receive it. This chute is pivotally connected IOO to the front side of a vertically-movable horizontal beam D, which' extends between the two front corner-posts a a. It has, preferably, on its ends guide-blocks d d, which enter and arev guided by vertical grooves a4 in the inner faces of the said front corner-posts. This beam also carries at its ends sliding bolts d2, which are adapted to enter holes a5 in said front corner-posts, whereby to hold the beam from vertical movements, and these bolts may be operated by levers d3.

The cradle is lifted and tilted by cables W W, which are located at its ends, which cables also operate to raise the beam D and chute E. Each cable W is doubled, and the loop passes under avshcave di, mounted in a yoke d4, secured to the end of the beam D. This is a form of connection between the beam and both strands of the cable which permits said strands to automatically equalize themselves, whereby the strain is the same on both. The two strands of the cable go u p to and over sheaves H H on the top of the tower, then down under sheaves 7c k, mounted in straps K, which are pivoted to the front corners of the cradle ou axes coincident with the axes of the rollers b3, then up to and over sheaves I I on the top of the tower, then down under sheaves/nn, mounted in the rear end of a bar N, which bar is pivoted to the frontside of the cradle and passes rearward under the same, and, finally, each cable goes up to and over sheaves M on the top of the tower and then down to a winding-drum P. A similar arrangement of sheaves, cable, dac., is found at each end of the cradle. When the winding up of the cable is begun, the beam D, if it is not bolted tothe cornerposts, will first be raised because it is lighter than -the cradle. When the beam D and also the chute E, which is connected with it, have been raised as high as desired, the bolts Z2 will be shot, whereby to connect said beam with the posts cl, a. The continued winding up of the cables lifts the cradle and its load bodily. When the cradle is first lifted, the tilting platform C, being lifted from the beams J J', is allowed to rock forward on its supporting-pivots c and does so rock until the top edge of the car Gr, which is on said platform,

- moves against the front side of the cradle or lagainst abutment-beams b5, secured thereto. Suitable clamping devices are provided, and they assist in holding the car upon the platform. These clam ping devices are verticallymovable bars R, having their upper ends fr bent over the top of the car. These bars are free to move up and down in guide-straps b on the inner face of the front of the cradle; but just before the cradle in its downward movement comes to rest the lower ends of these bars strike the foundation and are lifted out of contact wi th the car. When the cradle is lifted, these bars R fall by gravity until their upper ends engage with the upper edge of the car. The principal work of holding the car on the tracks after the cradle has been raised and tilted is performedby a plurality of cables or chains Q, which are attached to the front side of the cradle and pass up in the open front of said 'tower over sheaves q q, mounted at the top thereof, and then down at the rear side of said tower, there being attached to these depending ends counterbalancing-weights q of sufficient size to prevent the car from falling out of the cradle and to assist in lifting the cradle. The Winding up of the cables W, and consequent lifting of the cradle in a horizon tal position, `continues until the further vertical movement of the front side of the cradle isprevented. This result comes from the engagement of the notches 57 in the upper ends of the cradle-ribs b with pins d, secured to brackets 037 on the rear side of the beam D. These notches are in line with the axes of the wheels b3 o n. the ends of the cradle B. Pins he are also attached to the cradle in the same axial line, and they engage with notches d8 in the under sides of arms d, secured to beam D. As the cables are still further taken in the rear end of the cradle is lifted and the cradle turns upon said pins bs and d6 as pivots until the cradle and the car which it carries are tilted and take the position substantially as shown in dotted lines in Fig, 9. The cables or chains Q will obviously be brought into engagement with the top of the car, whose rear edge will engage with horizontal beams g3, secured to said cables, and the car is thereby held upon the tracks. The described tilting of the cradle is facilitated because of the transverse bars N, which are pivoted to its front side and have fastened to their rear ends the yoke n', in which the sheaves n are mounted. When the car is tipped into the position shown by dotted lines in Fig. 9, its load falls out in to the chute E, which is always in positionv to receive it, because the cradle tips on an axis carried by beam D. When the lifting-cables are paid out, the cradle swings back to its upright position, turning upon said pins bg and d? as pivots, and the further paying out of the cable permits said cradle and the car to move down. As it nears the foundation the clampbars R are lifted out of engagement with the car, as described. Then the ribs c3, having beveled front ends on the lower side of the tilting platform, strike the ribs J',y which lextend upward from the foundation, which causes the platform to move into a substantially horizontal position, as shown in Fig. 9, at which time the car may be rolled off and another car rolled on in its place.

The chute E is pivoted to the beam D at e, and its angle may be changed by taking in or paying out its cable at e. lThe chute preferably has a telescopic extension c2, which may be adjusted by its own cable and drum e3 e4, respectively.
