JJOX W. CARE, OF GBEELEY, COLORADO, .ASSIGNOB TO THE GREELEY MAN UFAGTUBING COMPANY, OF GBEELEY, COLORADO, A GORPOR ATION OF COLORADO.

DUMP-BED FOR VEHICLES.

Application filed September 14, 1909. Serial No. 517,615.v

To alli'whomit Be it known that I, Dox W. CARR, a citiley, county of Weld, and State' of Colorado,

have invented certain new and useful Improvements in Dump-Beds for Vehicles;

and I do declare the following to be a full,

clear, and "exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification.

My invention relates to improvementsin dump beds for vehicles and may be considered an improvement over the constructions set forth in my previous applications, serially tively. I

My present invention relates particularly the horizontal position, whereby it is prean operating shaft is employed provided with a worm which engages a worm wheel" mounted on". a shaft carrying twocone shaped operating drums with which are respectivelyconnected operating cables which engage" guide pulleys. mtermediate the.

tion as the worm shaft is operated.

My improvement consists in providing a pair of bars at each extremity of the vehicle.

Each pair of bars has two extremities pivotally connected with the stationary framework of'the vehicle, while their other extremities arepivotallyconnectedwiththedumpingbody on opposite sides of the center. The twomembers of each pair of locking bars cross each other when the dumping body is in the horizontal position, one of the bars bein provided with a recess which is engaged y the otherbar, thus serving to lock the body of the Vehicle in. the saidposition. One bar of each pair has one of its extremities engaged by a spring which, when the bar is in alinementwith the recess-of its companion bar, causes the one bar to slip into the recess of the other, and maintains the'actuated bar in the locking relation. -When it isdesired to dump the bed or wagon body, means are employed for moving the spring-actuated numbered 413,522 and 470,686, respecp in' either direction.

engage them from t erecessesof their companion bars, and while the spring-actuated bars are held in their disengaged position,

the operator turns the worm shaft, whichquickly tilts the dumping bed sufficiently to throw the locking bars into such relation as l to prevent-the spring-actuated barsfrom returning to the locking position until the dumping bed is again restored. 7

Having briefly outlined myimproved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawings in which is illustrated ,an embodiment thereof.

In these drawings: Figure 1 is an under: n'eath view of a-v'ehicle body, equipped with my improvements. Fig. 2 is a cross section taken onthe line 23-, Fig. "1, looking to- .ward the left, the'dumping body being in the horizontal position: Fig. .3 is a similar section, showing the dumpingbodyin the J tilted or dumping position. Fig. f'is a detail view showing the twovpa irs of lock-ing arms in connection with the mechanism for disconnecting the spring-a'ctuatedmember of eachpair from'its companion arm, the parts beingshown on a larger scale than in the other views. Fig. 5',is'-iasectional deta' il' -view, the section being taken on-thi'line 5--5, Fig. 2, the parts beingsh'o of a ments.

. The same reference characters indicate the enralarger scale. Fig. 6"i s' a rear end leyatio'nvehicle equipped with .my improve-1 journaled a shaft 6, carrying cone-shaped drums 7, having spiral grooves 8, engaged by cables 9, which engage guide pulleys 10 and 12,- mounted on the frame, the extremities of the cables remote-from their winding I drums being connected with the body of the vehicle on opposite sides, as shown at 13. The shaft 6 is provided with a worm wheel (not shown) which is engaged by a worm 14, on the operating shaft 15,'pro- Vided'with a hand crank 16. By turning this shaft 15, the dumping body may be tilted in. either direction.

' As heretofore stated, the function of locking the dumping body in the horizontal position is preferably accomplished by two pairs of locking arms which are substansite sides of the center, as shown at 22 and arm is located, the plate 30 being made fast pair of these arms is therefore sufiicient.

bolts.

. tremity of the arm 18 is slotted,-as shown at tially alike, one pair being located at each end of the vehicle. A description of one Let the

numerals

17 and 18 respectively designate the individual arms of each pair. The lower extremities of the two arms are pivotally connected with the stationary framework 5, as shown at 19 and 20, while their opposite extremities are pivotally connected with the dumping body 21 on oppo- 22 which in this case designate pivot Each arm 18 is provided with a central recess 23, adapted to receive the central portion of the arm 17, when thedump bed is in the horizontal position. The extremity of each arm 17, which is connected with the bolt 22, is acted on by acoil spring 24, one extremity of which engages the arm 17, while the other extremity bears against an angle bracket 25, connected with the dumping body, as shown at 26. This bracket is connected with the pivot bolt 22, upon which theextremity of the arm 17 is free to move, the boltengaging extremity of the arm being provided with a slot 27. The spring 24.- is so located as to press the arm 17 toward its companion arm 18, so that when the two arms are in the proper position, the one will engage the recess 23 of the other. Each arm 17 is composed of spring metal, and while its extremity opposite that engaged by the spring 24, may be secured tightly to the stationary framework, the arm nevertheless has sufficientyielding capacity to allow it to engage and disengage the recess 23 of its-companion bar. It is evident, however, that the extremity of the bar which engages the stationary framework may, if desired, be so connected therewith as to permit a suflicient oscillating movement to enable it to per form the aforesaid function, even if the arm were non-yielding. It is, however, preferred to employ an arm composed of spring metal and to secure the extremity connected with the stationary framework tightlyto the latter, since in.this event the resilience of the arm will aid the coil spring in forcing the arm 17 quickly into the recess 23 of the other arm, when the two arms are in the proper relative position. The upper ex- 28, and the bolt '22 passes through this slot and also through a bracket 29 between which and a plate 30, the extremity of the to a bar 31 of the dumping body. I

Fulcrumed' on the rear end of the dump bed, as shown at 31 is a lever 32. A pin 33 is connected with this lever on one side of the fulcrum, as'shown at 34, while a rod 35 is connected with the lever on the opposite side of the fulcrum, as shown at 36. The pin 33 passes through an opening 37, formed in the bar 31 .of the dumping body and has an expanded head 38, which engages the arm 17 of the rearwardly located pair of locking arms; while the extremity of the rod 35, opposite that connected with the lever is connected with the forwardly-located arm 17, as shown at 39. By virtue of its connection, when the lever 32 is thrown to the dotted line position (see Fig. 4), the two arms 17 i are also thrown to the dotted line positions in the same figure, whereby they are disengaged from the recesses 23 oftheir companion arms; and while the lever is held by one hand in the dotted line position, the hand crank 16, connected with the worm shaft 15, is turned with the other hand until the dumping body is moved sufficiently to prevent the arms 17 from reengaging the recesses'23 of their companion arms. The lever may then be released, after which the tilting operation is continued. After the contents of the vehicle body have been dumped, the latter is returned to the horizontalposition by reversing the rotation of the worm shaft, and as soon as the bed is restored, the arms 17, acting underlt he influence of the coil springs 24, and their own resilience, re'engage recesses 23 of their companion arms.

Having thus described my invention, what I claim is:

1. The combination with a stationary framework and a dumping body, of means for locking the body in the horizontal position, comprising a pair of cooperating arms arranged to cross each other, the upper eX tremities of thearms being pivotally connected with the body, while their lower eX-- tremities are pivotally. connected with the stationary framework, one of the said arms being provided with a recess adapted to receive the other 5 arm, whereby the two arms are constructed to interlock when the body is in a horizontal position, one of the arms being spring-actuated for the purpose.
