CAR-LOADER.

Specification of Letters Patent.

Patented May 1', 1906.

Application filed July 3, 1905. Serial No. 268,249.

.of operation is to force the grain into the cars by a blast of air, and a primary object of the invention is to feed the grain mechanically into the air blast and to hold the grain against back motion.

Another object is to provide for properly distributing the grain in the car.

Another object is to provide for escape of dust from the current of grain and air, and further objects relate to details of construction with a view to general improvement of the loader.

In the drawings forming part of this specfication the essential features of the invention have been illustrated in the construction thought to be most available and non-essentials have been in part omitted.

In Figure 1 the exterior of the loader has been shown in side elevation. Fig. 2 is a front elevation of the loader as it appears when not in use. section through. the operative parts of the loader. Fig. 4 is a section on lineX in Fig. 3. Fig. 5 is a central vertical section through the compound distributing conveyer or chute. Fig. 6 is a plan of the discharge end of the loader and the distributing-chute, showing the chute in operative position. Fig. 7 is an end view of a chute, showing how the tube is preferably flattened.

A grain-feeding compartment is shown at 1. A fan-casing is shown at 2, and at 3 is shown the discharge end of the grain-feeding compartment through which the grain is forced by the blast of air.

The opening through which grain passes to compartment 1 is shown at 4. At 5 is shown a horizontal shaft which extends lengthwise of compartment 1 and carries the spiral conveyer 6, and a cylindrical casing 7 encircles the greater part of the conveyer. A slot 8 is formed in the lower part of easing 7 at the discharge end thereof. An inclined chute 9 is formed beneath slot 8, and a slide-valve 10, controlled by rod 11', provides means for closing slot 8 more or less completely. The

Fig. 3 is acentral vertical discharge end 3 of the compartment 1 is inclined downwardly to direct the grain properly, and it is provided with a diverting-plate or partition which may be swung to one side or the other by means of rod 43 in order to divert the grain toward either of the two sidewise-extending chutes used to discharge the grain into a car.

The partition or diverting-plate is shown at 12, and its upper edge is preferably held in position between the two parts of which nose 3 is formed. The casing 7 is cut away at 13 at its outer end and near its upper surface, and the upper wall of compartment 1 is also cut away to form passages for dust, as shown in Fig. 4. A passage-way 14 is formed on the upper surface of compartment 1 in communication with the dust-passages 13 through casing 7, and a valve 15 provides means for controlling the escape of dust. A bracket 16 depends from the upper surface of casing 7 and forms a bearing for one end of shaft 5. Awall 17 coacts with the under surface of the casing 7 to form the air-passage 18, leading from the fan. The fan 19 is preferably supplied with blades 20 and 21, shaped as shown in Fig. 3, and it is mounted on shaft 22.

Grain passing from compartment 1 through nose 3 is delivered to the trunk or hopper 24 and forced therefrom through the chutes 25.

pivotally connected with the chutes, and it is notched at 27 to engage the bracket 28 when the chutes are raised. Two principal chutes, each designated by 25, extend sidewise in opposite directions from the trunk or hopper 24, and a third chute 42-extends directly forward midway between chutes 25. The central chute is smaller than the others,

and it has a mouth 42 inside the hopper,

which is adapted to coincide, approximately, with the discharge end of the inclined chute 9 when the chutes are raised. A valve 41 in chute 42 provides means for closing the chute to a greater or less extent, and this valve may be constructed in any desired manner. In

this instance the valve is shown hinged to a side of the chute and a set-screw 40 is screwed through a fixed, ut 39 to adjust the valve.

It is a matte! of mechanical construction to provide means for driving the different parts of the machine, and different environments may demand different constructions. I prefer, however, to provide shaft 5 with a pair of sprocket-wheels of different sizes, as 29 and 30, to mount sprocket-wheels 31 and 32 loosely on a counter-shaft 33, to connect wheels 29 and 30 with wheels 31 and 32 by means of chains 35 and 36, and to use a shiftable clutch-collar 34 to engage one or the other of the sprocket-wheels 31 or 32. When oats is to be loaded, shaft 5 is driven through chain 35, and when the machine is used to load corn the clutch-collar is shifted into ongagement with wheel 32 and shaft 5 is driven slower through chain 36.

The loader usually stands alongside a track with its conveyer chutes hanging down, as shown in Fig. 1 in solid lines. The car to be loaded is run alongside the elevator with which the loader is connected, the chutes 25, 25, and 42 are swung upward into the door of the car and held there by bracebar 26, and the curved chute-sections 44 are placed one on each of the conveyer-tubes 25, as shown in Fig. 6. When the machine is started, the grain to be loaded is fed by gravity into the mouth 4 of compartment 1 and is forced by the spiral conveyer 6 through casing 7 While a blast of air is developed by the fan and directed in the directions indicated by arrows in Fig. 1. The heavier grains settle to the bottom of the casing 7 and fall into the inclined chute 9 through slot 8, while the remainder is forced over the tail of the casing and into the trunk 24 of the conveyer-chutes. The grain passing through chute 9 is discharged into conveyer tube 42, and the remainder is divided into two streams, one of which is discharged to the right through one of the conveyer-tubes 25, while the other is discharged to the left through the other tube. The quantity of grain delivered to each tube 25 may be varied somewhat by the adjustable partition or deflector 12. The curved sections 44 are rotatable on tubes 25, and the rods 45 act as handles to permit the curved sections to be suitably manipulated. By turning the curved sections into different positions the grain may be discharged properly into different parts of the car. As a matter of preference, the curved sections 44 are flattened in crosssection, as shown in Fig. 7, so that a broader surface of grain may be exposed to the action of the air-blast and the grain be thereby more effectively and completely discharged. The tubes 25 of the discharge-chute are straight throughout their lengths and the curved sections 44 are also straight where they telescope on tubes 25 to permit rotary adjustment. The curved extensions of sections 44 are broadened sidewise, as shown in Fig. 7. As the grain is fed into the air-blast by the conveyer 6 it completely prevents back action of the blast by closing the grainpassage, and whatever back action the resistance of the grain may develop in the air-blast is used or may be used to carry dust through openings 13.

The invention is exemplified in the structure hereinbefore described, although it is not of necessity confined to this precise structure, and it is defined in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
