(C1. 26E-8) 1 This invention pertains to a car unloadingde vice and is for an apparatus for the unloadingr of bulk material from hopper cars or like con tainers. It has been especially developed for the unloading of iron ore from hopper cars, and it will be hereinafter described in that connection, but it may be likewise used for the unloading of other materials Where similar conditions are en countered. Iron ore is usually in a iinely divided condi tion. It tends to pack -into a very dense mass, and this packing is aggravated in the long haul ing of the ore in a railroad car from the place , l a ~ i positions in the car. Additionally, the ram. de vice is preferably providedfwith a rotatable work- ` ing end with mechanism for rotating vthe work ling end so as to drill or dig down into thema terial in the car. Moreover, the present inven tion contemplates that the implement in the Working end may from time to time be changed according to the material in the car. The implement is under the control 'of an'op erator, positioned ina cage on the crane. 'Thus the operator can move the crane and manipulate the unloading device and because of his elevated vantage point, is enabled to see and plan the op of the implement. Where it is loaded to the place where it is to be . eration In the accompanying drawings which ‘illus- ' unloaded. The packing is also aggravated by 'f1 trate one embodiment of my invention, the presence of moisture, and this is especially Figure 1 is an end View showing more orless so in cold weather when the moisture freezes. schematically the trackway, the position of the As a result of this packing and the extreme car to be unloaded, the runway for the crane, and reluctance of the material to flow, it is diilicult the unloading device depending from the trolley to discharge it from the hopper cars in which it - is shipped. The present methods require the services of a crew of laborers who haveto get into the car and work with picks and crowbars to dis lodge the ore. This is not onlyvery hard work, and disagreeable work, but consumes consider able time and is expensive. The present invention provides an implementv of the crane. The implement is shown in a po sition where it is projected Well down into the car; ' Figure 2 is a top plan view of the arrangement shown in Figure 1; Y . Figure 3 is a side elevation, the View being at right angles to Figure 2; . ‘ Figure 4 is a detail view similar to Figure carried from an overhead crane which may be l, showing a lesser portion of the crane and show manipulated to all the necessary angles and con ing in dotted lines the retracted position of the ditions in the car to accomplish the unloading of 30 implement where it is clear of the car; ; the ore or other material.

According to the present invention, there is provided along the >trackway where the car is to be unloaded, which is usually anl elevated track way or trestle, an overhead crane, lthe runway for which is parallel with the tracks along which the car moves. 'Movable back and'forth on the traveling crane is a trolley or carriage. This trolley or carriage supports a ram or like imple ment, and mechanism on the carriage is pro vided for moving the ram up and down, i. e., lon gitudinally of its axis. Other mechanism is pro vided for swinging the implement in a direction fore and aft of the car from a vertical position. to the implement and also showing a portion of the implement through which the tilting ofthe implement is effected, the view being a trans verse plane of line 5-5 of Figure 6; Figure 6 is a longitudinal section on a larger scale of the implement showing a portion of the gearing through which the implement is raised and lowered, and also showing the gearingy through which the tilting is accomplished, the View also sho-wing the drive by means of which the operating element at the end of the imple ment may be rotated; Thus the implement can be operated vertically line l--l of Figure 5; or inclined in either a fore or ait direction. It may be elevated and rammed down into the ma terial in the car. By movement of the trolley the implement; crosswise of the track, the'implement can be moved transversely across the full width of the car.

As shown in Figure 8, the outer end of the shaft I9 is provided with a gear 31. The trunnion I2 has a « reduced extension I2a on which is a sleeve 38, , which sleeve is provided with aV gear 39 that meshes with the pinion 31.

The lower end of the shaft 24, where it passes through the bearing 2|, is provided with a sleeve 32, which sleeve has a downwardly extending flange forming a socket 33.

The only motor which is movableV with the ramV is the motor 3l that serves to rotate the tool at the lower end of the ram.
