My invention relates to improv racks for trucks or wagons.

The object of. my. inventionis to provide an improved beet rack adapted. to be carried by a truck or'wagon, whereby the beets or other articles carried in the rack can. be readily dumped therefrom, and at the same timeproviding means whereby. the swinging side is automatically returned to its closed lozpositionand automatically locked.

. Another object of my invention is toprovide a rack of this character in which the swinging side is held in its closed position by two chains and provided with means for li rsimultaneously releasing both of the chains, whereby the swinging side is adapted to swing down by the weight or pressure of the beets or other articles in the rack, and are allowed to pass from the rack.

A further object of my invention is to provide a rack of thisrcharacter which is very durable, simple in construction and provided with certain details of structure and combination of parts hereinafter more fully set forth. r

In the accompanying drawings t Figure 1 is a side elevation of my improved rack showing the swinging side locked inv its upward position. a

Figure 2 is a similar view showing the chains released so that the weight of the beets or the other articles in the rack will cause the side to swing downwardly.

Figure 3 is a transverse sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a side elevation showi side swung downwardly.

I Applicant is aware that racksof this character are old in the art, in which the swinging side is held in its upward or closed position by means of two chains adapted to interlock with slots, such as shown." in Patent No. 1,315,386. In such a structure as shown in this patent, it requires two persons to release the swinging side, or else a single person-has to walk to one end to release one chain and then to the other end to release the other chain. In such structures, the chains are re-v leased by striking the same with a bar to disengage the links- 0f the chain from theslot ements in ng the 1928'. serial No. 294,963.

and there. is no assurance that the chains will 1 pass freely-through the eyes and allow the swinging side to swing all the way downas the chains are often caught in the slots and the swinging side stopped at an intermediate point.

In my impr singlemovement of the levers, and: the slots closed bysaid means so that the chains passing freely through the eyes can not pass into the slots tostop the swinging movement; of the sideat an intermediate point.

Referring now tothe drawings, 1 represents my: improved rack, which is of a shape and size to fit the chassis of a truck or the running gear'of a wagon, and whileI have shown this-rack specially designed forhan dling beets, it will be understood that the same could be used in handling grain or many other farm products, and the same idea could beusecl in otherplaces where a swinging door or gate is used.

Therackl, as shown,has the side 2 hinged to the bottom 3 means of hinges 4 and 5. These hinges, as shown, are of strap form,

oved rack the two chains are -s1multaneously forced out of'the slots'by a and the straps 6 forming one portion ofthe v hinge 7 extending a considerable distance across the bottom of the rack, and the straps 7 secured to the side 2 extending entirely across the side and above the upper edge thereof, as will be hereinafter more fully described. In order that the side 2 will automatically return to its vertical or closed position after the weight or pressure of the contents thereof is taken off, I provide a coil spring 8 which has its two ends 9 and 10 extending therefrom mid-way between the diameter of-the coil. The end 10 isrigidly fastened to the bottom 3 of the rack and the other half extending beyond the side 2 of the rack. The end 9 normally holds the side 2 in the position shown in Figure 1 of the drawings, when there is no pressure thereon; Secured tol'the ends 11 of the rack are the hooks 12 to which the chains 1 3 and 14: are connected and by this arrangement it'will be seen that the chains are readily detached from the body of the rack. Y

The straps 7 of the hinges,- as heretofore slots 17 the same may be gripped by hand for operat-l ing the samel A link 23has its ends pivot stated, extend upwardly above the upper edge of the side 2 of the rack and are provided with the enlarged portion 15, which extends slightly to one side. The enlarged portions above the edge ofthe side2 areprovided with circular openings 16 having communicating with their lower ends the obliquely arranged "Pivoted upon thestraps 7, at 18 and 19, are the two levers 20 and21,which have their lower ends offset as indicated at 22, whereby ally connected at 24 and 25 to the levers 2O and 21 below the pivots .18 and 19, whereby the said levers are connected. .to operate together and by moving either lever the other L isoperated. The upper ends of the levers 2O and 21 are providediwith enlarged heads 26 int horizontal plane with the lower edge of the=slots- 17 when the levers are in the position shown in Figure 1 of the drawings. E i tending from the said fiat edges 28 and29 are two circular edges 30 and 31 which are in the same are of a circle as that of the opening drawnd-ownwardly into the slots 17 and the and 27 having flat edges28 and 29; which are 16 in the enlarged port-ions 1510f the strap 7 The chains .13 and; 14 pass throughthe opening 16. and are. provided atthe'ends with weights 82 and 33, whereby the chains are links thereof are prevented from sliding in the slots, and theside 20f the rackis held ings.

in the position shown in Figure 1' of the draw- IVVhen it isdesired to dump the rack anfop erator standing ateither end, either pushes or pulls one of the levers 20 and 21, which causes "the fiat edgesQS and 29 to engage the links ofthe chain 13. and 14: and gradually force them upwardly out of the slots 17, and.

' the cont-inued'movement of'the lever causing the slots to be closedwith the curved edges S0.ancl:31 covering the slots,'whereby circular openings are maintained to allow the free passage ofthe chains therethrough. -Theupper ends of the levers 20 and 21 are provided withlugs 34: and 85, which engage theenlarged portion 15 of the straps 7 and limit the movement of the levers so as to as sure the' positionshown in Figure 2 of the drawings. The moment the chains are forced out of the slots 17 the pressure of the contents circular openings 16. 7 After the rack has been of the rack will. force the side 2 downwardly and the chains will freely pass through the dumpedthe spring 8 normally returns it to the closed position and the levers 20 and 21 l are returned to the normal positions'hown in Figure 1 or the drawings,and the links of the chains 13 and 14 will find their way into the slots17 and the sideis again locked against downward movement.
