Abstract
ABSTRACT OF THE DISCLOSURE
A dump truck stabilizer to prevent a dump truck from falling over on its side when unloading. The dump truck frame is fitted at its rear end corners with notched flanges adapted to engage, when the truck backs up, a stabilizer rod supported at its ends by two spaced pillars.
The ends of the stabilizer rod have excentric coaxial pivot pins each rotatable in a sleeve mounted in the pillar. Thus, the stabilizer rod adjusts automatically to the required level when engaged by the truck flanges. The excentric rods at the ends of the stabilizer rod are also mounted for limited back-and-forth movement relative to the pillars and are biased towards a frontward limit position. Thus, the biasing means constitute a shock absorber device, should the dump truck back up too quickly, and also enable the stabilizer rod to fully engage both grooves in the flanges of the truck, should the truck be not fully perpendicular, to the transverse stabilizer rod.

Description
~067032 The present invention relates to a structure designed to stabilize a dump truck while the truck is tilting its dump box to empty a load.
Modern dump trucks ran8e from the relatively small ones~
little bigger than a panel truck to the massive trucks which are able to carry heavy loads of several tons. It ls mostly these trucks which may experience a particular danger when unloading. Such trucks are equipped with a dumping mechanism which raises the dump box to an almost vertical tilt to ensure that all of the contents of the dump box can 51ide out thrcugh the rear opening. However~ as frequently happens~
some or much of the load remains in the dump box, even while it is tilting and only slides out when tbe dump box is almost in its final almost vertical position. This is especially the case with the heavy clotted dense material, such as wet sand or earth, frequently carried in construction work. The result is that the center of gravity of the entire truck is raised to a h~gh, dangerously unstable level as the dump box tilts upwards. If the load slides down unevenly, more on one side of the dump box than on the other, the truck may fall over on its side. This danger increases if the truck is unloading on a transversely slanted surface, with a consequent greater risk of injury to the driver, damage to the truck and spillage of the load.
Accordingly, it is an ob~ect of the present invention to provide a stabilizing means for an unloading dump truck.
It is another object of the present invention to provide such a stabilizing means ~hich is effective, fail-proof and which requires only slight modifications to a truck.
It is still another object of the present invention to provide a stabilizlng means adaptable to many different trucks havlng varying light, moderate or heavy loads.
These objects are accomplished in accordance with the invention by the provision of a floor flanked on either side by a block-shaped pillar of suitably strong material. A transverse rod extends between the two pillars at a suitable height above the floor. To use the _ 2 -`` ~067t)3Z
stabili~er a truck is equipped on each side of its frame at the rear with a rearwardly extending flange which has a rearwardly facing groove adapted to receive the rod of the platform. To unload, a truck is backed onto the floor so that both grooves of the two flanges fitted to the frame of the truck engage the transverse rod.
Thus, as the dump box is being raised, the truck is at all times held in a stable position by the transverse rod engaged ln the grooves on each side of the truck frame.
The above will be re clearly understood by reference to a preferred embodiment of the invention illustrated by way of the accompanying drawings~ in which:
Fig. 1 is a perspective and sectioned view of the stabilizer;
Fig. 2 is a sectional view taken along line 2-2 of Fig. 1~ also showing in elevation the rear end of a truck in position on the floor with the flanges just engaging the transverse rod;
Fig. 3 is a top plan view, partly in plan section, of one pillar showing one end of the rod and the shock-absorbing assembly;
Fig. 4 is a sectional side view looking along line 4-4 of Fig. 3;
Fig. 5 is a perspective and partially sectioned view of one excentric end of the rod; and Fig. 6 shows two cross-sections of the rod in lower and higher positions to explain how it ad~usts automatically to the lever of the dump truck frame.
In the drawings, like reference numerals indicate like elements throughout.
A platform 1 is preferably made of steel or iron and generally rectangular in shape having a series of spaced-apart vertical ribs 2 sandwiched between upper panels 3 and 4 lower panel, as best seen in Fig. 2. The front edge of platform 1 is provided with a flat slant 5 permitting the wheels of a truck to easily roll onto platform 1 which forms a floor.
In each of both rear corners of platform 1, a pillar 6~ on the left, and a pillar 7, on the right, are located. Both pillars 6 and 7 are substantially of block-shape and have a step 8 facing 1067()32 towards the front of the platform 1. The frontmose inside corner edge 9 of both pillars 6 and 7 is bevelled at an angle of approximately 4S
degrees.
A transverse rod lO, relatively thick and strong~ is ro~atably mounted in pillar 6 and pillar 7, extending between them.
A dump truck adapted to use the stabilizer has a flange 11 secured by bolts 12 to the frame 13 of the truck on each side, at ~he rear. Fi~. 2 shows only one such flange~ the other not being visible as the view is taken from one side of the truck. Fig. 2 shows only a portion of the truck frame 13 and a wheel 14 is illustrated in dashed outline. Each flange ll is provided with a groove 15 opening toward the back and having a semi-circular end of slightly larger diameter than the diameter of the rod 10~ so that groove 15 may enga8e rod 10. The lower arm 16 of groove 15 extends further rearwardly than the upper arm 17 and edge 18 of arm 16 is curved downwardly to facilitate engagement of rod 10 as the truck is moving backwards~ if rod 10 is slightly lower than groove 15. Edge 10 of upper arm 17 is curved upwardly for the same reason in the event that rod 10 is higher than groove 15. Once groove 15 fully engages rod 10~ the dump box 20 of the truck may be tilted about pivot 21 and emptied as shown by the dashed outline of Fig. 2. Even if the load in the du~p box is unevenly distributed~ rod 10 effectively prevents the truck from falling toward either side.
Rod 10 has, at both of its ends, a crankarm 22 from which extends a shorter rod 23 which is excentric relative to rod 10. Each rod 23 is mounted in a box-like casing 24. Rod 23 is surrounded from crank-arm 22 to its end, by a cylindrical sleeve 25 welded or otherwise secured within casing 24. Inside sleeve 25, are spaced two brass bearings 26 for rotatably supporting rod 23. The two excentric rods 23 at each end of the rod 10 are coaxial and allow rod 10 to automatically rotate when engsged by flanges ll and thus be positioned in different vertical levels~
as shown clearly in Fig. 6 to compensate for different possible heights of flange ll installed on different types of trucks~ also for the same type of truck carrying variously weighted loads and, finally, to 10~032 allow raising of the truck frame as the truck unloads.
Casing 24 is slidably located within a box-shaped enclosure 27 secured within the top portion of pillar 6 and pillar 7. A helical compreSsion spring 28 acts as a biasing means to keep rod 10 in a frontward position in which each casing 24 abu~s against a removable cover plate 29 of enclosure 27. Casing 24 is slidably supported within enclosure 27 between an upper set 30 and lower set 31 of spacer plates which can be added or substracted from either set to adjust the height of casing 24 within the pillars~ Cover plate 29 is affixed to pillars 6 and 7 and can be removed for access to the spacer plates, the casing 24 and end rod 23.
Helical springs 28 serve to absorb any possible shock of impact on rod 10 if a truck backs up a little too quickly and also serves to permit transverse alignment of rod 10 with grooves 10 to fully engage bOeh grooves, even if the truck is not fully perpendicular to rod 10.
Obviously, pillars 6 and 7 could be anchored directly in the ground, or in a concrete base~ and the floor l can be any t~pe of surface or the ground itself.
