a receptacle and providea shipping receptacle'with a closure that can be easily and quickly secured over the open end-of'thereceptacle and whlch will mt as ihi ldi g or guidingchute when the "receptaeleyis :dumped.

"Another. objectof-the invention is to :pro- "videa receptacle with a closure-so constructed and arranged that it can be easily and quickly secured over the open end and furthermore can-be readily'ireleased when the receptacle isitobe' dumped.

Further-objects of the invention will'appea-r fromitheefollowing specification taken in 525 connection. with thedr-awing which formsa part ofrthis application and in which I V Fig. :1 isa perspective'view of a receptacle and closure constructed in accordance with the invention V V i Fig. Qisan elevationalviewtaken at right angles'to "Fig. I; o I Fig. 3 is an;elevat ion al view partly in section andat-right angles to Fig. 2;

The invention-briefly described consists of form .or shapeand has one end, preferably theupperend, open. ".Theoreceptacle is pref- .erably provided with trunnions 1 on which it 145 may .b tilted, v

' The open end ofthe receptacle is closed by a flexible sheet of material, preferably water I roof such as a canvas sheet. The sheet is wrappedaround the'receptacle and is then folded inwardly, the upper end thereof being folded downwardly across'the top of the receptacle and over oneedge thereof. The free end of the closure is secured inv any desired manner, as by a clamping bar. vl/Vhenthe res ceptacle is to be dumped this bar is removed and the receptacle is tilted whereupon the 7 material in thereceptacle will be discharged,

the flexible sheet acting during this operation as a shield or chute to prevent the material from blowing or being scattered in the air.

Further details of the invention will appear from the following description.

, Inthe embodimentof the invention shown in the drawing there is illustrated a receptacle .10 which maybe of any desired form or shape :andis preferably constructed of steel. The

receptaclelO is provided with trunnions ll which are disposed "below the center of grav-' ity of the receptacle when thereceptacle is loaded and supported on its'basel '70 The upper outer edge of the receptacle has formed thereon or secured thereto a ring 12. The'closure for thereceptacle consists of a sheet .13of material, preferably water proof 'inateriah'suchas canvas or duck.- .The sheet I 13 is wrapped around the upper edge portion ofthereceptacle, the edges preferably being overlapped, as shown in dotted lines in Fig. 1 andthe overlapping edges, may, if desired,

bestitched.

. A rQP or C0r d15 is secured to theinners surface of the-flexible sheet at a point spaced from the upper end thereof and a similar cord 16 is secured'tothe' outer surface. jThese cords are so spaced as to cli'sposethein on opposite edgesof a clampingstrap 20 which may, if desired, be formed in two or four: parts, the adjacent sections being provided with flanges 21by which the sections can be secured together. This arrangement is particularly shown in Fig. 4 wherein it will be seen that the rope 15 is disposed beneath the ring 12 and above the clamping strap or straps 20 and the rope 16 is disposed belowthe clamping strap or straps.

After the sheet has been secured around the upper edge portion of the receptacle in the manner described it is drawn upwardly and folded inwardly, as shown in Fig. 1, the free end of the folded sheet being carried downwardly over one edge of the receptacle and clamped beneath a bar 25 which is carried by bolts 26.

lVhen the receptacle is'to be dumped, hooks 27 carried by a yoke 28 are lowered into en gagement with the trunnions 11 and the re-' ceptacle is then raised. The tilting of the receptacle on the trunnions is normally prevented by a latch member 30 which normally engages a lug 31 carried by the receptacle, the latch being mounted-on one of the hooks 27. When the receptacle has been swung to the position in which the contents are to be dumped and the bar 25 has been removed, the latch 30 will be released and the receptacle will be inverted, the contents being discharged downwardly through the flexible sheet of material, which in this operation, functions as a guiding chute. I

From the foregoing description it will be seen that simple and practical closure means has been designed for closing a shipping receptacle and that the closure when released will act asa chute to prevent the material from being scattered.

' Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the ar-- rangement of the various cooperating parts may be made without departlng from the spirit or scope of the invention, as expressed in the'following claims.

What I claim is:

1. A receptacle, having a single open side a closure therefor comprising a flexible member secured aroundthe edge portion of said open side of the receptacle to form a continua tion of the walls of the receptacle, and folded across saidopen side of the receptacle, and

means securing the folded member across said open side. 7

2. A receptacle, having a single open side a closure therefor comprising a flexible member secured around the edge portion'of said open side of the receptacle to form a continuation of the walls of the receptacle, and folded across said open side of the receptacle, and

means on the outer surface of the receptacle and adjacent an edge of the open side secur ing the folded member across said open side.

3. A receptacle, having a single open side and a closure therefor comprising aflexible sheetsecured around the receptacle to form forming a continuation of the wallsof the re ceptacle, said closure having a member secured thereto and disposed below said laterally extending portion of the receptacle, means for securing the closure around the receptacle, and means for securing the sheet across the open side of the receptacle.

5. A receptacle having an open upperend and a portion extending laterally from the upper end,a closure for the receptacle comprising a chute of flexible material extending around theupper end and having a cord secured thereto and disposed below said laterally extending portion of thereceptacle, means for securing the cl'osurearound the recepta-.

the open end of the receptacle; 9 r

6. A receptacle having an open upper end,

cle. and means for securing the chute across a closure comprising sheet of flexible matel folded around the upper end portion of the receptacle, clampingmeans extending around the receptacle and closure sheet for securing the sheet, and means carried by'the sheet and disposed below said clamping means for preventing upward displacement of the sheet. 1

-7. Areceptacle having an open upperend' and an external flange on the upper'edge, a sheet of flexible material folded aroundthe upper endportion of the receptacle, aclamp disposed below the flange and securing the posed below the flange and-below the clamp 8. A receptacle having an open upper end and an external flange on the upper edge, a sheet of flexible material folded around the upper end portion of. the receptacle, a'clamp disposed below'the flange and securingthe sheet, means carried by the sheet and dis-.. posed below the flange and below the clamp for preventing upward displacement of the sheet, and means for securing the folded 010- sure sheet over the open end of the receptacle. 9.
