The lower reach of the belt 33 is positioned over the pulley 46 and between the pulley 31 and the pulley 46 the lower reach of the belt 33 is supported by a plurality of spaced pulleys 48l rotatably supported in bearings 49 which are mounted on portions of the frame I2.

Mounted on a suitable support 58 on the I beams 25 I provide an electric motor 5| having an armature shaft 52 on which I provide a sprocket 53. At the rear of the motor 5| I provide a shaft 54 (Fig. 2) which is rotatably supported in

chair housings

55 and 56. The shaft 54 has a large sprocket 51 and a small sprocket 58 thereon. The sprocket 53 and the sprocket 51 are connected by an endless sprocket chain 59 (Fig. 4).

Intermediate the length of the lower inclined portion of the frame |2 I provide a transverse shaft 68 rotatably supported at one end by the housing 56 and at the other end by a chair housing 6| on the opposite side of the frame |2. In

lthe housing 56 the shaft 68 has a large sprocket 62 thereon and in the housing 6| has a reduced sprocket 63 thereon. The sprockets 58 and 62 are connected by an endless sprocket chain 84.

The shaft 3| has a large sprocket 65 thereon in the housing 6| and the

sprockets

62 and 65 are connected by an endless sprocket chain 66.

When the motor 5I operates the upper reach of the belt 33 travels from the front end towards the rear of the apparatus.

As indicated in Fig. 1 the forward portion of the device includes a loading area L and a loading and distribution area D at the rear of the loading area. At the rear of the distribution area D the opposed flat portions 20 of the skirts I9 each has a vertical flange 61 extending downwardly from the inner edge thereof to within a predetermined distance above the belt 33 (Fig. 11) and which extends forwardly a predetermined distance.

Clamped to each of the vertical flanges 61 adjacent the lower ends thereof I provide a flexible rubber guard member 68 which contacts the upper surface of the belt 33.

Within the distribution area D forward of the vertical flanges 61 I provide opposed distributing guide members 18. The guide members 18 are identical so but one will be described in detail.

vAs shown in Figs. 5 to l0 inclusive a guide memhorizontal flange 18 extending from one side of the web and positioned a predetermined distance above the belt 33 and supports the end of the guide 18. Adjustably mounted on the web 11 I provide a hinge plate 88 having a plurality of elongated apertures 8| therein and having a plurality of vertically aligned apertured hinge lugs 82 thereon. The hinge plate 88 is secured to the web 11' by a plurality of bolts 83 and nuts 83 the bolts being positioned in the elongated apertures 8| of the hinge plate and in suitable apertures in the web 11.

Positioned on the rear wall 12 of the guide 18 adjacent the end wall 15 I provide a plurality of vertically aligned apertured hinge lugs 84. The hinge lugs 84 of the guide 18 are aligned with the hinge lugs 82 of the hinge plate 88 and a suitable hinge pin 85 is positioned in the apertures of the hinge lugs 82 and 84.

Intermediate the bracket -16 and the forward end of the guide 18 I provide a plurality of support brackets 86 which like the brackets 18 are mounted on certain of the transverse braces 11 of the sled. Each of the brackets 86 includes a vertical web 81 and a horizontal portion 88 positioned a predetermined distance above the belt 33, and is engaged by the bottom wall 14 of the guide 18. The vertical web 81 terminates at a position wherein it forms a stop engaged by the rear wall 14 of the guide 18 when the guide is in a fully retracted position.

Adjacent the forward end of the guide 18 I provide a bracket 98 which like the

brackets

16 and 86 is mounted on one of the transverse braces 11 of the sled. The bracket 98 includes a vertical web 9| which terminates similarvto webs of the brackets 86. Extending from one side of the web 9| the bracket includes a horizontal flange 92 positioned a predetermined distance above the belt 33 and engaged by the bottom wall 14 of the guide 18.

Mounted on the rear wall 12 of the guide above the bracket flange 92 I provide a plate 93 having a pair of elongated arcuate apertures 94 therein, the axis of the apertures being identical with the axis o-f the hinge pin 85. The plate 93 is adjustably secured to the bracket 98 by a pair of bolts 95 and nuts 96 the bolts being positioned in the elongated apertures'94 of the plate 93 and in suitable apertures in the flange 92. v

When the nuts 96 are loosened the guide members 18 may be swung from their fully retracted position as shown in Fig. 5 to Fig. 10 inclusive, towards each other to their fully extended position as shown in Fig. 1 or any intermediate portion desired. v

Mounted on the guide 18 adjacent the bottom thereof I provide a resilient wiper member 91 which is clamped to the front wall 1| by a. suitable clamping bar 98 which is secured to the front wall by a plurality of bolts 99. The wiper member 91 engages the upper surface of the belt 33 and prevents material on the belt from passing under the guide 18. y

Mounted on the end wall 15 of the guide 18 I provide a resilient wiper |88 which overlies the adjacent end of the wall 61. 'I'he Wiper |88 is shown as secured to the wall 15 by a plurality of bolts |82. 4

Within the loading area L forward of the guides 16 I provide opposed load-ing guide members |85. The guide members |85 are identical so but one will be described in detail. As shown in Figs. 12 to 16 inclusive a guide member |85 is in the form of an elongated box like structure including a front wall |86, a rear wall |81, a top wall |98', a bottom wall |89, a rear end wall |I8 and a front end wall The front wall |86 eX- tends below the bottom wall |89 to within a predetermined distance above the belt 33. As shown in Figs. 13 and 14 the rear portion of the guide |85 is positioned within the forward portion of the guide 'I0 which has a shelf 2 therein on which the guide `|05 rests.

Adjacent the end wall of the guide |05 the guide l0 has a pair of spaced vertically aligned apertured hinge lugs ||3 therein.

On the end wall 0 I provide an apertured hinge lug II@ which aligns lwith the hinge lugs |I3 and a suitable hinge pin |I5 is positioned in the apertured hinge lugs |3 and Ill.

Intermediate the length thereof the guide |25 is Asupported by a plurality of brackets I I6 which are mounted on certain of the transverse braces TI of the sled similar to the brackets 'I6 and 86. Each of the brackets ||6 includes a vertical web II'I which above the belt 33 has an aperture IIS therein in which the guide is positioned. (See Fig. l5.) Extending from each side of the web I7 above and below the aperture i8 the bracket includes horizontal flanges I I9.

Mounted on the guide I 05 adjacent the bottom thereof I provide a resilient wiper member which is secured in position by a suitable clamping bar I 2| secured to the front wall |06 by a plurality of bolts |22. The wiper |20 like the wiper 97 engages the upper surface of the belt to prevent material on the belt from passing under the guide |05.

Mounted on the under face of the bottom wall i 29 adjacent the front end and adjacent the wall I |36 I provide a pair of spaced channel irons |26 and I2? which extend beyond the front end of the guide ||5 a predetermined distance. (See Figs. 3 and 16.) Positioned between the anges of the channels |26 and |21 I provide a block |28 having a threaded recess |29 therein. The threads in one of the block apertures are right handed and the threads in the other are left handed.

Positioned in the threaded aperture |29 I provide a similarly threaded sleeve I 30. The two sleeves |30 are mounted on and secured to a rod i3! which is shown in Fig. 12 as supported intermediate its length in a bearing |32 depending from the deck 2|. Outwardly from each of the sleeves |30 the rod |3| has one portion of a universal joint |33 mounted thereon. (See Figs. 12 and 16.) The other portion of the universal joint is secured to a rod |34 which is positioned in a pipe |35 which extends through the side wall of the sled and terminates flush therewith. (See Fig. 17.) rIhe rod |34 terminates intermediate the length of the pipe |35 and th-e end thereof includes a flattened key portion |36.

Adjacent the outer end the pipe |35 is preferably internally threaded as at |31 to receive a threaded removable closure plug |38.

To swing the guides |05 an operator removes one of the closure plugs |38 and inserts the rod 'I 39 in the pipe |35 and moves it into engagement with the rod |34 with the key |36 of the rod |34 positioned in the slot IM of the rod |35. Thereafter by rotating the han-d wheel Ill@ the operator can swing the forward ends of the guides either inwardly or outwardly.

Thus it will be seen that the guides I0 in the distribution area D may be set .to various positions and the guides |05 in the loading area L may be adjusted to various positions at any time by operating the hand wheel I 40.

The device I0 is primarily adapted for use on large excavating projects for loading trucks with material excavated by a drag line scoop. The excavated material is placed on the belt 33 within the loaded area L and the belt conveys the material upwardly and over the pulley 30 from whence it drops into a truck therebelow.

From the foregoing description it will be apparent that I have provided an improved heavy duty loader which is simple in construction and highly efficient in use.
