DUMPING CAR OR WAGON.

SPECIFICATION forming part of Letters Patent No. 566,175, dated August 18, 1896. Application filed May 26,1896 Serial No. 593,143. (No model.)

To all whom it may concern:

'Be it known that I, J OSEPH GALES Hot.- COMBE, a citizen of the United States, residing at Newport, in the county of Lincoln and State of Oregon, have invented certain new and useful Improvements in Dumping Oars or iVagons; and I do hereby declare the fol-' lowing to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in dumping cars or wagons intended for use in railroad construction, or for filling in hollows, or for dumping excavated material, or for like purposes.

The said invention will be understood by reference to the accompanying drawings, in which the sameparts are indicated by the same letters and numerals throughout the several views.

Figure 1 represents a longitudinal section through the car along the line 1 1 of Fig. 2 and looking in the direction of the arrows 1.. Fig. 2 represents a section along the line 2 2 of Fig. 1 and looking in the direction of the arrows 2. Fig. 3 represents an end view as seen from the left of Fig. 1 and looking in the direction of the arrow 3. Fig. 4 represents a section along the line 4 4 of Fig. 1 and look- Y ing in the direction of the arrows 4, except that the upper frame or platform of the car is tilted, as in dumping; and Fig. 5 represents an end View of the car, showing a modified form of hand-lever for dumping the car.

A represents the frame of the oar-truck,

which is provided with cross-timbers A and A and the end timbers A above which are mounted yokes A for the pivot-pins of the upper frame or car-platform. This truckis mounted on the wheels B and axles O in the usual way.

D represents a longitudinal shaft carrying one or more pinions D, meshing in the racks e at the base of the intermediate frame E,

which frame is provided with a plurality of brackets E, between which are journaled the antifriction-rollers E and E These rollers E travel on the tracks a over the cross-pieces A, while the upperv rollers E support the curved tracks F which support the upper frame or platform of the car F. This intermediate frame is provided with overhanging lips e to engage the side timbers E and with inclined faces 6 to clear the bottom of the upper frame or platform when the said platform is in the tilted or dumping position.

The upper frame F is provided with crosstimbers F and F?, the latter terminating in ribs f, projecting above the main body of the platform and forming ends thereof, as also adding additional strength to the structure. These various cross-pieces are faced on the lower side with metal tracks F which bear on the rollers E, as already described.

The platform proper is composed of a plurality of cross timbers or boards F which are preferably strengthened by means of metal bars or ribs f while small bars or ribs f are placed over the end pieces f, but these metallic strips or bars may be omitted or replaced by wooden strips, if desired.

In order to prevent the upper frame F from being moved too far longitudinally in dumping, the cross-pieces F are provided, which pieces are faced with metal plates f adapted to engage on suitable projections on the intermediate frame, such asthe boxes or brackets E. The upper frame F is provided with end pins H, which, when the car is in the normal horizontal position, project between the guide-bars a of the yoke A, but do not rest in the Y thereof, thus normally serving merely as lateral guides, as indicated in Figs. 2 and 5.

The bottom of the upper frame F is provided with a plurality of bent ribs F which are inclined downward, as at 1, then upward,

as at 2, then horizontally, as at 3, and then finally curved in the center, as at 4:. (See Figs. 2 and 3.) These ribs are secured to the cross-timbers F and the longitudinal I timbers F as shown in Fig. 2.

In order to turn the shaft D, a hand-lever, such as D (shown in Figs. 1 and 3) or D (shown in Fig. 5,) is provided. The upper end of this lever may be normally held in the link A which is adapted to be raised and of the pins H down in the operation of dumping. If for any causeit should be desired to rem ove the car-platform or the upper frame,this pin a is removed and the upper frame F removed and suspended by slings engaging the hooks G, which are provided for this purpose.

The car is loaded in the ordinary manner, the parts being in the position shown in Figs. 1., 2, and 5.

In Fig. 5 a modified form of hand-lever is shown, in which the lever D is supplied with a ratchet-and-pawl arrangement, such as D which, being the well-known form of ratchetand-pawl arrangement, will not be further described. By means of this arrangement the hand-lever D can turn the pinion D and the shaft D through any desired angle, whereas with the lever such as D it becomes necessary to remove the lever after the same has been turned through an angle of somewhat more than ninety degrees. Now if it be desired to tilt the car the lever D or D as the case maybe, is turned to the right or left, according to which way it is desired to dump the car. The revolution of the shaft D and pinions D" will move the racks c outward, causing the rollers E to pass beneath the tracks F". The first motion of these rollers IE will be to ride up on the inclines 2, while the opposite rollers will enter into the curved portions 4 of the tracks F This will ease the upper frame down until the pins H rest on the yokes A Then these pins will serve as pivots for the upper frame F. Further motion of the intermediate frame will cause the rollers E to ride still farther up on the inclines 2 until the center of gravity of the frame F is so far disturbed as to tend to rotate freely toward the side that is inclined downward. At this time this tendency of the platform to rotate will assist that of the handlever to move the intermediate frame from beneath the upper frame, and as soon as the rollers E pass clear of the tracks F the whole of the upper frame will swing about the pivotpins H until the inclined faces of the tracks F strike the upper edge of the frame A in the position shown in Fig. 4. After the car is dumped, to restore the parts to the initial position it will be simply necessary to run the intermediate frame back beneath the upper frame, first swinging the platform to the approximately horizontal position, and then lifting the same, as will be readily understood.

It will be seen that in the process of loading and transporting the loaded cars the platform is supported on the rollers E and E and is steadied in place by the pins H against lateral motion on the said rollers, while in the process of dumping the platform and connected parts are lowered to rest on the pivotpins 11, and are then swung about these pivotpins into the dumping position. In this way,

although it is necessary to lift the unloaded platform a short distance in restoring the parts to their initial position, this disadvantage is more than overcome by the weight of seams the platform and also of the load thereon 00- operating in the process of-dumping the car.

It will be obvious that various modifications of the herein-described apparatus might be made by any practical mechanic which could be used without departing from the spirit of my invention.

Havingthus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
