FRANK L. HAGUE, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO FEGLIES CONSTRUC- TION COMPANY, LIMITED, OF FORT WILLIAM, ONTARIO, CANADA, A CORPORATION OF .CAN ADA.

Application filled larch 25, 1921.

To all whom it may concern:

Be it known that I, FRANK L. HAGUE,

a citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain newand useful Improvements in Box-Car Unloaders, of which the following is a specification. a

The object of my invention is to provide an apparatus by means of which the contents of a box car, such as a small (grain car, can be easily and quickly unloade A further and particular object is to provide an apparatus for removing the gram lying in the angle between the floor of the car and the side wall when the car is tilted on a longitudinal axis from its normal hOIlzontal to an inclined position.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a side view of an unloader apparatus embodying my invention,

Figure 2 is a slde elevation, partlally in section, of one end of the apparatus, showing-the operating mechanism therefor,

Figure 3 is a transverse sectional view through the unloader belt supporting mechanism, I

Figure 4 is a plan view of the apparatus, showing the means for oscillating the unloader belt and its supporting frame on a vertical axis,

Figure 5 is a transverse sectional view on the line 55 of Figure 2,

Figure 6 is a transverse sectional vlew through a portion of a freight car, showing my improved unloader belt operating in the angle of the car between the floor and the side wall.

Figure 8 is a sectional view on the line 8-8 of Figure 7.

In the'drawing, 2 represents a suitable base on which is mounted a stationary upright column 3. 4 is a sleeve mounted to slide vertically and rotate on said column. This sleeve is provided with an outwardly BOX-CAR UN LOADER.

Serial No. 455,501.

projecting bracket 5 whereon the unloader mechanism is supported, as will hereinafter be described in detail. The outer end of the bracket 5 has an upwardly turned portion 6 and a yoke 7 has vertical ivots 8 on the end 6 and is adapted to oscil ate laterally on said plvots to shift the unloader belt from side to side. This shifting movement is effected by any suitable mechanism, preferably by means of a quadrant 9 mounted on the o e 7 and meshing with a spur pinion 10 t at is secured to a shaft 11 which has bearings in the end 5 of the bracket and is driven through shafts 12 and 13 and a suitable gearing from the worm 14 on the shaft of an electric motor 15. I This motor is mounted for forward and reverse movement so that the shaft 11 may be revolved in either direction to oscillate the yoke 7 to the right or the left, as may be desired. A castm 16 is pivoted at 17 in the yoke 7 and has a earmg for a feed screw'18 that is operated through a belt 19 from an electric motor 20. Brackets 21 depend from the casting 16 and shafts 22 and 23 are mounted in said bracket and have sprocket wheels 24 to engage belts 25 on which sweeping or scrap:- ing blades 26 are mounted at intervals, said blades being preferably in the form of brushes, gradually increasing in length from the ends to the middle, as indicated in Figure 6, to form a brush of such shape that it will fit into the angle of the car between the floor and side wall when it is tilted, as shown in Figure 6, and thereby the material, such as small grain in the angle of the car, will be swept clean therefrom toward the dis- .are also provided, one upon each side of the pipe 27 and in parallel relation therewith. The outer end of the pipe 27 has a hanger 29 thereon supporting the shaft 30 of the conveyer belts and hangers 31 and 32 are mounted on the inner portion of the pipe 27 and support sprocket wheels 33 and 34 which engage theupper run or stretch of the un- V loader belt, as shown in Figure 1. The hanger 31 slides on the pipe 28 in projecting and retracting the pipe 27 and the hanger 32 is mounted on pipes 28 and forms a guide for the pipe 27. A yoke is mounted on the inner end of the pipe 27 and also slides on the pipes 28, the purpose being to project and retract the .conveyer belt within the car to be unloaded, and at the same time maintain the desired tension of the belt. The yoke 35 is loosely mounted on the (pipe 27 so that when the yoke reaches the on of its travel inwardly on the pipes 28, the pipe 27 may slide in said yoke and travel to the inner end of the operating screw.

A sweeping movement of the belt is effected by suitable means, such as an elec-.

tric motor 36 for operating a belt 37 which has driving connections with the shaft 22 of the unloading belt. By this mezins the unloading belt may be operated at the desired speed to sweep the grain out of the car and particularly out ofthe an is between the floor ofthe car and'the si e wall when the car is tilted on a longitudinal axis.

I also prefer to provide means for tilting the unloader belt on a horizontal axisthat is, the pivot 17.. Arms 38 are mounted on the yoke 39 that is carried by the sleeve 40 journaled in the casting 16 concentric with the screw 18. Cables 41 connect the arms 38 with piston rods 42 of fluid pressure cylinders 43. By this means, when fluid pressure is applied simultaneously to the cylinders 43, the casting 16 will be oscillated on its horizontal plvot 17 to raise or lower the outer end of the unloader belt and adapt the brushes to the work.

It may be desired, however, to rock or tilt these brushes to adjust them in the angle of the car, and I may then operate one of the cylinders 43 and rock the pipes 28 and the screw driving motor 20 with the sleeve 40 in its bearings in the casting, as indicated by dotted lines in Figure 3, the pipe 27 and the operating screw 18 being stationary during such movement and when the desired tilting position is obtained, the screw ma be operated through the motor 20 to pro ect or retract the belt and adjust its brushes to the work.

In Figure 6 I have shown a freight car 44 tiltedupon a suitable supporting platform 45 to the desired angle so that the brushes of the unloader belt can operate in the space between the side wall and the floor of the car and sweep the material accumulated therein when the car is tilted toward the door of the car or other discharge opening.

It is desirable in an apparatus of this kind to provide means for oscillating the unloader belt supporting bracket on a ver tical axis, such as the column 3, and Itherefore provide an electric motor 46 having a worm 47 meshing with a worm wheel 48 on a horizontal shaft 49 which drives a parallel shaft 50 through a sprocket belt 51. This shaft 50 has a. sleeve 52 splined thereon provided with clutch members 53 adapted to alternately engage the peri hcry of a clutch member 54 that is mounte on a shaft 55 that is geared to the gear ring 56 secured to the sleeve 4. A lever 57 controls the friction clutch members 53 sliding them on their shaft toalternately engage the clutch member 54 and transmit motion through the shaft 55 to the gear ring 56 and rotate it on the uprightcolumn 3 to change the horizontal position of the bracket.

Referring to Figures 7 and 8, it is desirable to provide means for raising and lowering the unloading belt supporting track and I therefore provide a cylinder 58 in the base of the hollow column 3 having a piston 59 and a rod 60 connected therewith and pivotally attached at its upper end to a bar 61 that is mounted transversely in the sleeve 4 and is slidable vertically in the slot 3 in the wall of the column. The sleeve is formed in upper and lower sections, as indicated in Figure 7, with the cross bar 61 intermediate to these sections and positioned to allow freedom of rotary movement of the sleeve sections of the column to provide for the lateral oscillation of the bracket and horizontal adjustment of the unloading belt. Admission of fluid pressure to the cylinder 58 is provided for by means of the pipe 62 and a duct 63 connects the upper portion of the cylinder with the atmosphere to provide for freedom of movement of the piston in the cylinder.

The base supporting the upright column 3 may be mounted upon suitable trucks 64, as indicated in Figure 1, to allow the convenient movement of the apparatus from place to place and permit it to be adjusted upon a track opposite and- 'adjacent to another track on which the car to be unloaded may be standing. The track is adjusted vertically to allow the insertion of the unloader belt arm into the car and then the belt may be swung horizontally and tilted until it is positioned to sweep through the angle between the floor of the car and the side wall and collect the small grain that 2.
