-1-'particularly to containers for use with-transportin'g and dumping devices such as those disclosed in my prior patents.- More particularly still this invention Vrelates to transporting and dumping containers having a plurality of compartments adapted to be dumped either through the front, through the bottom, or through both front and bottom of each compartment.
It isthe object of the present invention to provide'a novel transporting and dumping container having-a plurality of compartments whichcan be dumped either through the front, through the bottom,i or through -both front and bottom of each compartment.-
Otherand further -objects of the present in- Y vention will appear as the description thereof proceeds.
. An-ulnstranve embodiment of the present in` vention is shown in the accompanyingidrawings but it is -to be expressly understood that this embodiment is shown in the drawings and described hereafter for the purposes of illustration only.
To determine the scope of the present invention reference should be had to the appended claims.
In the accompanying drawings,
Fig. 1 is a rear view of an illustrative embodiment of the novel container of the present invention;
Fig. 2 is a front view, of the novel container of Fig. 1;
Fig. 3 is a top view of the novel container of Fig. 1;
Fig. 4 is a cross-sectional view of the novel container of Fig. lon the line 4-4 with the cradle swung down and the front members swung ontwardly as shown in dotted lines;
Fig. 5 is an enlarged detail of a portion of the novel container of Fig. 1 showing in detail the locking device for the bottom members;
Fig. A6 is another view of the enlarged detail ci' Fig. 5;
Fig. '7 is an enlarged detail of a portion of the novel container of Fig. 1 showing the locking device ior the front members;
Fig. 8 isv an enlarged detailof a portion of the novel container of Fig. l showing a part of the hollow end walls and the lifting mechanism for the front members; and
Fig. 9 is an enlarged detail of a portion of the ncvel container of Fig. 1 showing a part of the' hollow center partition and the lifting mechanisin for the front members.
In the accompanying drawings, in which like reference characters indicate similar parts, a
novel container is there shown having a rear wall I0 to which is suitably secured a bail I I adapted to be-engag'ed by the automatic hook or catch of the transporting and dumping device. Secured to rear wall I0 are suitable side walls I2 terminating in reinforcing strips I3. A reinforcingv member I4 connects side walls I2 at their lower front edge. Secured to the middle of rear wall I0 and extending forwardly are a pair of plates I5 and I6 adapted to form a hollow centervpartition dividing the container into two separate compartments. Side walls I2 vare provided with suitable plates I1 spaced therefrom and parallel thereto to form hollow side walls for the container.
Suitably hinged to rear wall I0, as by hinges I8, are bottom forming members I9, one for each compartment, bottom members I9 being suitably reinforced as by channel members 20. Likewise, hinged'to rear wall I0, as at 2l, is a cradle 22 (Fig. 4) carrying upstanding members-'23 provided with suitable pins 24 to receive the chains of the transporting and dumping device. Bottom/members I9 are designedto rest upon cradle 22 and may be opened or closed by the rotation of cradle 22 about its hinges 2I.
. Bottom members I9 are locked in closed position by suitable pins 25 passing through the front vthe appropriate hollow end wall and the other the hollow `center partition when bottom members I9 are closed. Upstanding -members 28 swing out of the hollow end Walls and the center partition to form chutes for directing the flow of discharged material when bottom members I9 are opened. I
Hinged to member I4 are front forming members 29, one for each compartment, each member 29 being provided with suitable hinges 30. Each front member 29 is provided with upstanding side members 3l one adapted to enter the appropriate hollow end wall and the other the hollow center partition when front members 29 are closed. .Front members 29 are provided with suitable reinforcing members 32 and are locked in closed position by suitable bolts 33 (Fig. 7). Bolts 33 pass through tongues 34 which are secured to the center' partition and the side walls of the container and pass through suitable openings 35 formed in the front members 29. Bolts 33 are adapted for ready removal.
Secured to the side walls and the center partition and passing across the top of the container are suitable reinforcing members 36 and 31 which have mounted thereon suitable bearings 33 and 39. Rotatably mounted in bearings 38 is a shaft 40. Rotatably mounted in bearings 39 is a shaft 4I. Secured to shaft 40 are suitable sheaves 42 and 43, sheave 42 extending into its appropriate hollow .end wall and sheave 43 extending into the hollow center partition. Secured to shaft 4I are suitable sheaves 44 and 45, sheave 44 extending into the hollow center partition and sheave 45 extending into its appropriate hollow end wall. Shafts 4l! and 4I are suitably machined to receive a hand crank 41. Sheave 42 is bored at 49 to receive a suitable locking pin to lock it against rotation. Sheave 45 is likewise bored as at 50 to receive a suitable pin 5I passing through openings in end wall I2 and plate I1 to lock sheave 45 against rotation (Fig. 8). Each of sheaves 42, 43, 44 and 45 is provided with a suitable cable 52 which -is secured at one end to the sheave and at the other end to the upper edge of one of front members 29, as at 53.
With the novel container of the present invention constructed as above described when it is desired to transport material therein the compartments are filled, the chains of the transporting and dumping device attached to pins 24 of cradle 22 and the container raised from the ground and transported to the dumping position. When dumping position is reached the container is elevated until bail II engages the automatic hook or catch. If it is desiredv to dump the contents of the compartments through the bottom of each compartment, pins 25 are withdrawn and the chainspof the transporting device lowered, allowing cradle 22 to swing about its hinges 2|. Bottom members I9 rotate about their hinges I3 and members 23 withdraw from the hollow end walls and the center partition and the material in the compartments is dumped. It is obvious that if it is desired to dump one of the compartments only, then only the pins 25 for the appropriate bottom member I9 are withdrawn and when cradle 22 is rotated about its hinges only the bottom member I9 for that compartment will open.
If it is desired to Vdump the compartments through their fronts then the bolts 33 are withdrawn. Thereafter bolts 49 and 5II are withdrawn and the weight of the material pressing against front member 29 will rotate them upon their hinges 30 withdrawing members 3| from the hollow end walls and the center partition, sheaves 43, 43, 44 and 45 rotating shafts 4l! and 4I and the material will be dumped. Thereafter hand crank 41 is engaged in turn with each of shafts and4I and shaft 40 and 4I manually rotated to wind cables 52 upon the sheaves 42, 43; 44 and 45 to swing the front members 29 back to closed position after which bolts 33, 49 and 50 are replaced. It is apparent that either compartment can be dumped by the removal of the appropriate bolts 33, 49 or 50. It is also apparent that the compartments can be dumped both through the front and the bottom at the same time or that one can be dumped through the front and the other through the bottom as may be desired.
It is now apparent that the present invention provides a novel transporting and diunping container having a plurality of compartments which can be dumped .either through the front, through the bottom or through both front and bottom of each compartment.
Changes to or modifications of the above described illustrative embodiment of the present invention may now be suggested to those skilled in the art without departing from the inventive concept of the present invention. For instance, more than two compartments may be provided by the use of additional partitions. A
To determine the scope of the present invention reference should be had to the appended claims. i Y
