LOCKING ASSEMBLY AND METHOD
Background of the Invention
The present invention relates to a locking assembly and to a method of locking a wear tooth to a tooth adaptor, typically utilised in the mining, agricultural, or other earthmoving industries.
In particular, the present invention relates to a locking assembly which, by provision of a retaining means in a dual part format, various advantages are achieved.
Description of the Prior Art
The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement or any form of suggestion that that prior art forms part of the common general knowledge in Australia.
Various locking arrangements are presently known, for locking one or more wear tooth to it's respective tooth adaptor(s).
Traditionally , such teeth are welded to the tooth adaptor such that as the tooth wears out, the old tooth is removed and replaced by a new tooth, which is welded into position.
In more recent times, various methods for the removable attachment of such teeth and other wear plates have been developed, eliminating welding operations. All such systems, however, generally include at least one through hole or orifice on a vertical or horizontal plane, through which a pin is inserted, however, such systems have the disadvantage that the strength of the devices are compromised.

Detailed Description of Preferred Embodiments
Throughout the drawings, like numerals will be used to identify similar features, except where expressly otherwise indicated.
As shown in Figs. 1 to 10 of the drawings, a locking assembly, generally designated by the numeral 1 , include a wear tooth 2 adapted to be retained on a tooth adaptor 3 by means of retaining means, which generally designated by the numeral 4. As will be readily observed from the drawings, the locking assembly of this embodiment of the present invention is characterised by being provided with at least one, but preferably two, slots 5, in the or each side portions of the tooth 2, such that they cooperate with corresponding slots 6 in each side of the tooth adaptor when in the engaged position, to then receive retaining means 4.
The retaining means 4 of the present invention includes a pair of cooperating parts, a first part 7 having a shaped edge surface adapted to cooperate with a complementary shaped edge surface of second part 8. The shaped edge surface 10 of the second part 8 of the retaining means 4 is provided with a lip 11 adapted to be provided rearwardly of a protruding part 12 of the shaped edge surface 13 of the first part 7 of retaining means 4, as detailed in Fig. 5.
The cooperating parts 7 and 8 of the retaining means 4 are assembled by firstly providing the first part 7 into the position shown in Fig. 7 within the cooperating slots. Thereafter, the second part 8 is inserted in the manner illustrated in Fig. 8 to a position shown in Fig. 9 such that the lip 11 is forced past the protruding portion 12 of the first part 7 and is effectively locked in to position, locking the wear tooth 2 to the tooth adaptor 3. The inserted position of the retaining means is illustrated in schematic sectional view in Fig. 10.
To disassemble the wear tooth 2 from the tooth adaptor 3, a lever means is inserted into an orifice 15 provided in the second part 8 of retaining means 4. Once inserted, the lever is
moved in a substantially arcuate manner, such that the second part 8 of retaining means 4 becomes disengaged from the first part 7 and is removed from slot 5. Once the second part 8 of retaining means 4 are both removed from each slot 5, the wear tooth 2 may be removed from the tooth adaptor 3.
It will be observed that, due to the design of the retaining means, the first part 7 need not be removed from the slot 6 in order to remove the tooth 2 from the tooth adaptor 3. Furthermore, due to the design of the first part 7, it is easily inserted into the slot 6 and retained therein in position, during insertion of the second part 8. Furthermore, during removal of the second part 8 of retaining means 4, when the lever is moved in the arcuate manner and the second part 8 rotatably is brought outwardly of slot 5, the front surface of first part 7 is against the inward surface of the tooth 2 ensuring easy removal of the second part 8 of retaining means 4.
It will be appreciated therefore that the present invention provides a unique locking assembly which, due to its design, is easily able to releasably secure a wear tooth 2 to a tooth adaptor 3. In use, the wear tooth of this design displays high structural integrity providing unrestricted flow of overburden during use of the tooth. The forces present in the locked position are illustrated by the arrows in Fig. 10. Minimal wear occurs at the side positions of the tooth 2, where the retaining means is removably inserted.
It will be appreciated that the retaining means may be inserted into position by imparting a force to the second part 8, and this may be provided by striking a hammer or the like against a striking pad 17.
It will be appreciated that the various components of the present invention may be constructed of a variety of materials, such as steel or other metal. The retaining means could, of course, be formed of other materials, such as plastics, and would be appropriately chosen depending upon the forces required to be sustained by those components, etc.
The present invention therefore provides a locking assembly 1, and a method for locking wear teeth 2 to an adaptor 3, which may be used in a variety of applications, such as earthmoving, mining, washery, crushing equipment, or other earthmoving equipment.
It will be appreciated that a variety of shapes of the various components may be provided whilst still achieving a similar functional operation.
For example, Fig. 11 illustrates an alternative embodiment of the present invention, whereby, for each pair of first parts 7 of the retaining means 4, a single or connected second part 8 is provided for insertion in the slot 6. Fig. 11(a) illustrates the first parts 7 ready for insertion, Fig. 11(b) shows the first parts 7 inserted in the slots 6, Fig. 11(c) illustrates the provision of the tooth 2 to the tooth adaptor 3, and Fig. 11(d) illustrates the final step of placement of the second parts 8 into the slots 7, whereby the tooth is thereafter connected to the tooth adaptor, ready for use.
In Fig. 12 is shown how the second part is secured and released from its locked position. As shown in Fig. 12(a), the second part is inserted into position by rotating it into the slot 6, and then, as shown in Fig. 12(b), by striking it with an appropriate dolly and hammer until the clip locks into place. To remove, it may be levered out by a crows foot tool as shown in Fig. 12(c).
The arrangement of Figs. 11 and 12 also highlights the positioning of the locking arrangement in an alternative position, that is, rather than in the side of the tooth, on the top surface.
Figures 13, 14 and 15 show another embodiment of the present invention for releasably locking a wear tooth 2 to a tooth adaptor 3 in which a first retainer piece 16 and a second retainer piece 17 are held in place by a locking piece 18 which communicates with and releasably locks the first retainer piece 16 relative to the second retainer piece, and a rigid bracket or bridge 19 extending across a portion of the slot 6 to substantially brace the retainer pieces when in the locked position.
The first retainer piece 16 and the second retainer piece 17 each include threaded slots or holes, 21 and 20 respectively, which are substantially aligned when the retainer pieces 16 and 17 are installed in the wear tooth slot 6 and tooth adaptor cavity during locking. The locking piece 18 is a threaded-screw which complements the threaded-slots or holes of the first and second retainer pieces 16 and 17. The threaded-screw is inserted into the substantially aligned first retainer piece slot and second retainer piece slot during locking as shown in Fig. 15 .
A shown in Fig. 13, the rigid bracket 19 is mounted to the adaptor 2 at two points on the adaptor surface so as to form a bridge, the position of the bracket piece 19 being selected by a person skilled in the art such that when the second retainer piece 17 is inserted into the wear adaptor 6 and tooth adaptor cavity and releasably locked to the first retainer piece 16, the bracket piece 19 will contact with the second retainer piece 17 so as to prevent any substantial movement of the retainer pieces 16 and 17.
All such variations and modifications of such nature should be considered to fall within the scope of the invention as broadly hereinbefore described and as hereinafter claimed.
