Crowder Attorney, Agent. or FirmPhillips. Moore. Weissenberger Lempio & Strabala [57] ABSTRACT A loader bucket has a stinger bit movably mounted on a bottom wall thereof for movement between a raised position coplanar with the bottom wall and a lowered. digging position therebelow. Positioning means are provided on the stinger bit and bottom wall of the bucket to selectively hold the stinger bit in either the raised or lowered position during an earthworking operation.
18 Claims, 2 Drawing Figures 1 STINGER BIT FOR LOADER BUCKETS BACKGROUND OF THE INVENTION The draw-bar pull required by a loader working in hard-packed material oftentimes reaches a sufficiently high magnitude to inhibit the earthworking operation. It is therefore necessary to resort to a loader having a substantially higher draw-bar horsepower to complete the work. In many such work applications. a contractor is unable to procure such a loader, thus resulting in undue economic losses.
SUMMARY OF THIS INVENTION An object of this invention is to overcome the above briefly described problem by providing an economical and noncomplex stinger bit for an earthworking implement, particularly a loader bucket, which is adapted to increase the operational efficiency and versatility thereof. The loader bucket comprises a bottom wall having a cutting edge disposed forwardly thereon and an opening formed through the bottom wall which movably mounts the stinger bit therein. Positioning means on the stinger bit and bottom wall cooperate to selectively hold the stinger bit in either a raised position substantially coplanar with the bottom wall or in a lowered, working position.
BRIEF DESCRIPTION OF THE DRAWINGS Other objects of this invention will become apparent from the following description and accompanying drawing wherein:
FIG. 1 is a front perspective view of a loader bucket having a stinger bit of this invention mounted thereon; and
FIG. 2 is a side elevational view of the loader bucket with portions thereof broken away to more clearly disclose the stinger bit.
DETAILED DESCRIPTION FIG. 1 illustrates a loader bucket adapted to be attached on a loader in a conventional manner by a pair of laterally spaced lift arms 11 and a tilt linkage comprising a pair of links 12. The loader bucket comprises a bottom wall 13, normally disposed horizontally during an earthworking operation, having an interrupted two-part cutting edge I4 disposed forwardly thereon. A rectangular opening 15 is formed through the bottom wall and has a stinger bit 16 mounted therein.
Referring to FIG. 2, the stinger bit is adapted to be moved manually between a raised position, generally coplanar with respect to bottom wall 13, and a lowered phantom-lined position below the bottom wall. FIG. 1 also discloses the stinger bit in its lowered position whereby it is adapted to substantially lower the drawbar horsepower required during an earthworking operation. In its raised position, a cutting edge 17, disposed forwardly on the stinger bit, is disposed in substantial linear relationship with respect to two-part cutting edge 14.
The stinger bit further comprises a substantially flat bottom plate 18, also disposed in coplanar relationship with respect to bottom wall 13 of the bucket when the stinger bit is raised, and an upwardly curved deflector portion 19 extending rearwardly from the bottom plate. A downwardly curved plate or cross-brace 20 extends downwardly from the rearward end of deflector portion 19 and is secured to the bottom plate. The bottom plate terminates at its rearward end at an upwardly curved portion 21 which is pivotally mounted on a pair of laterally spaced brackets 22 by a pivot pin 23.
Deflector portion 20 is preferably concentric with respect to the pivot axis of pin 23 as well as a rearward edge of the bottom wall, defining opening IS. The height of deflector portion 19 and such concentric relationship insures a substantially close fit between bottom wall 13 of the bucket and the stinger bit to prevent the egress of loaded material therebetween. Pivot pin support brackets 22 are disposed laterally inwardly of lift arms 11 to prevent interference therebetween upon tilting of the bucket on the lift arms by links I2.
The stinger bit further comprises a pair of laterally spaced and vertically disposed side plates 24 (one shown), each having a horizontally disposed first flange 25 secured thereon to extend outwardly from a respective side plate. The flanges comprise positioning means for holding the stinger bit in its lowered position of operation when engaged with a top surface of bottom wall 13. The positioning means further comprises a pair of lugs 26, each releasably attached to bottom wall 13 of the bucket by a bolt 27.
The inner end of each lug engages a like-shaped first notch 28 formed on an upper edge of side plate 24. When it is desired to raise the stinger bit to its FIG. 2 position, bolts 27 are removed along with lugs 26, the stinger bit is raised and the lugs are inserted into a second set of second notches 29, each formed between a lower edge of a side plate and bottom plate 18. In such position, second flanges 30 engage a bottom surface of cutting edge 14.
It should be understood that the above-described loader bucket and its attached stinger bit may be suitably modified without departing from the spirit of this invention. For example, the stinger bit could be set back into bottom wall I3 of the bucket from the position shown in FIG. I and cutting edge 14 could thus comprise a single continuous member. Also, the raising and lowering of the stinger bit could be accomplished by a suitably attached and remotely controlled hydraulic actuator, for example. In addition, reinforcements could be welded or otherwise suitably secured to bottom wall 13 on either lateral side of the stinger bit to increase the overall structural integrity of the loader bucket.
