This invention relates toa novel bagging platform for coal trucks. Under some circumstances, coal isdischarged from a truck directly into a coal-hole in a sidewalk. Under other circumstances, a long chute is used to deliver the coal through "a Window into a coal-bin. Where neither of these methods is practicable, canvasbags or. other appropriate receptacles are filled with coal, and carried into the building. This invention aims to provide a truck with a convenient platform, upon which the bags may be placed while they are being filled, and to provide means whereby the platform, when not in '15 be moved out of the way.

The invention will be best understoodby reference to the following description, when taken in connection with the accompanying drawings of one specific embodiment thereof,

while its scope will be more particularly pointed outin the appended claims.

In the drawings:

Fig. 1 is a side elevation of a portion of a coal truck equipped with a bagging platform the invention, shown in position for use;

2 is a side elevation of the same, showingthe platform as it appears when folded. D

, bars ll by pivots 18, the bars 15 being placed up out of the way when not in use; and Fig.3 is a perspective view of the bagging platform as it appears before being attached to its supporting brackets on the truck.

Referring to the drawings, and to the embodiment of the invention which is'illustrated therein, there is shown in Figs. land 2 a truck body 5 of the elevating and dumping type commonly in use for handling coal and other loose materials. In Fig. 1, the body is shown in an elevated and inclined posi tion, while in Fig. 2, it is shownin its lowered horizontal position. These bodies are usually built of heavy sheet metal, and have a perof the body, as by a pair ofbrackets which use, may

comprise a horizontal portion 7 and an oblique brace 8, secured as by bolts9 and 10 to the body. These hrackets'afford pivotal support for a suitable frame, herein comprising bars 11 connected to. thebrackets by pivots 12, to swing about a horizontal axis extending transverselyofthe body.- As shown in Fig. 3, these 'bars are rigidly connected together by bars 12. "When the platform is in use, this frame. occupies the position shown in Fig.1, with the bars 11 disposed vertically. Swinging movement of the frame inwardlytoward the under side of the body is conveniently limited by providing the bars12-with lugs 13, adapted to engage, the under sides of the bracketsl70, shown" in Fig. 1. When,however, the platform is notto be used, this frame-can be, swung from the position shown in-Fig. ,1 to that shown in Fig. 2, where it will be up out of the 'way.-

- The frame afiords pivotalsupport for the platform proper, comprising a fioor plate 14, side bars 15 and across-bar 16, which project above the upper surface of the floorplate, and constitute ledges, and/a second cross-bar :17 below the' floor plate. Herein, these several bars areangle irons, conveniently secured to the plate. The bars 15 are connectedto the on theinner sides of the bars 11 to facilitate the foldingof the structure into the position shown in Fig.2. When the platform is in po sition for: use, as shown in Figs. land 3, down ward, swinging movement-of the-floor is pre-.. vented by appropriate means, herein chains 19, provided at their lower ends with S-hooks 2O hooked into the openings '21 in the bars 15, respectively, while the upper 1 ends of the chains are-provided with terminal eyes22, secured tothe bars 11, as by'bolts 23.

When the platform is in position for-use, its floor affords support for a receptacle 24, shown in. dotted lines in Fig. 1 beneath the sheet 6. ,After the receptacle hasbeen filled, it can be removed conveniently onto the back of a man,as the floor is to be a sufficient height from the ground to enable this to be accomplished conveniently. When the plat form is notto be used, it may be folded. up out of the way, as shown in Fig. 2, and secured in its folded position by appropriate means, such as a screw 25 threaded into a bracket 26 on the rear wall of the body, and adapted to engage the V-shaped channel pre sented by the angle bar 17, which is then inverted. The platform remains in this position at all times, except when it is to be used for bagging operations.

Having thus described one embodiment of the invention, but without limiting myself thereto, what I claim and desire by Letters Patent to secure is:

1. In an apparatus for handling loose ma terials, the combination of a body having an outlet for the material, and a folding receptacle-receiving platform comprising a frame pivotally mounted on said body, a floor pivoted to said frame for movement from a position below said outlet to an inverted position above said outlet, and means connecting said floor to said frame to limit downward swinging of said floor relatively to said frame.

2. In an apparatus for handling loose materials, the combination of a body having a rear wall provided with an outlet for gravity discharge of the material, a folding platform structure comprising a floor normally disposed below said outlet where the receptacle receives the gravitating material and adapted to be folded upwardly, and a frame to which said floor is pivoted to swing upwardly about a horizontal transverse axis, said frame being pivoted to said body to swing upwardly about a horizontal transverse axis to an upwardly directed position in which said floor is downwardly directed from the first-mentioned axis. 1

3. In an apparatus for handling loose materials, the combination of a body having an outlet for gravity discharge of the material, a folding platform structure comprising a floor normally disposed below said outlet where the receptacle receives the gravitating material, a frame to which said floor is pivoted to swing about a horizontal transverse axis out of the way of the gravitating material, said frame being pivoted to said body to swing about a horizontal transverse axis, and means connecting said floor to said frame to limit downward swinging of said floor relatively to said frame.

4. In an apparatus for handling loose materials, the combination of a body having an outlet for the material, a folding platform structure comprising a floor normally disposed below said outlet, a frame to which said floor is pivoted to swing about a horizontal transverse axis, said frame being pivoted to said body to swing about a horizontal transverse axis, means connecting said floor to said frame to limit downward swinging of said floor relatively to said frame, and means below said axis to limit swinging of said frame inwardly toward the under side of said body.

5. In an apparatus for handling loose materials, the combination of a body having a rear wall provided with an outlet for the material, a folding platform structure comprising a floor normally disposed below said outlet, and a frame to which said floor is pivoted to swing upwardly and forwardly into an in verted position, said frame being pivoted rearwardly of said wall to swing rearwardly and upwardly to a position at the rear of said wall, and then forwardly toward said Wall into an inverted position in which said floor is again inverted into a position in which it depends from its pivot in a position between said wall and said frame.

(5. In an apparatus for handling loose materials, the combination of a body having an outlet for the material, and a folding, receptacle-receiving platform comprising a frame having bars pivoted to said body at opposite sides of said outlet to swing from a vertical depending position rearwardly, upwardly, and then forwardly, and a floor pivoted to said frame to be moved first from a horizontal position upwardly with relation to said frame and then carried bodily by said frame to a depending position above said outlet.

7. A folding bagging platform for trucks, the same comprising a horizontal fioor,a normally vertical frame to which said floor is pivoted to swing upwardly, then forwardly, and finally downwardly, and means connecting said floor to said frame to limit swinging movement of said floor downwardly relatively to said frame.

8. A folding platform for attachment to the rear wall of a dumping truck, the same comprising a support, a frame pivoted to and normally depending from. said support, said frame and said support having cooperating means limiting swinging movement of said frame in one direction, a normally horizontal floor pivoted to said frame and foldable from a horizontal position upwardly towardsaid frame, said frame in turn being foldable upwardly to a position above said support, in which position said floor is inverted and extends obliquely downward, a second support, and means to secure said floor to said second support.
