Abstract

An apparatus for attachment to the bucket of a front end loader, skip loader or any other power-operated bucket. The apparatus comprises a plurality of teeth supported in a frame that attaches to the bucket of a front end loader. The apparatus may be used to sort unwanted material, e.g., small and large pieces of wood, rocks and waste products such as manure, from dirt and then to transfer the unwanted material into the bucket of the loader.

Claims

1. An attachment for the bucket of a front-end loader, the bucket having a back, a bottom with a forward end having a plurality of transverse attachment holes, and sides, each of the sides having at least one bucket mounting hole, the attachment comprising:

a rake comprising;

a plurality of teeth oriented substantially parallel to one another in a row, each of the teeth having a front end, a middle portion and a back end, and each of the teeth at the ends of the row having a rake mounting hole therein;

a back transverse member to which the back ends of the teeth are attached;

a middle transverse member to which the middle portions of the teeth are attached, the middle transverse member forming a pocket that is configured to receive the forward end of the bucket, the middle transverse member having a plurality of transverse mounting holes therein that align with the transverse attachment holes on the forward end of the bucket for attaching the attachment to the forward end of the bucket by bolting; and

at least one transverse rod perforating and supporting the teeth between the points of attachment of the middle transverse member and the front ends; and

two end brackets, each of the end brackets having a rake attachment hole at one extremity that aligns with the rake mounting hole on one of the end teeth and a bucket attachment hole at a second extremity that aligns with the at least one bucket mounting hole on the bucket for mounting of the rake on the bucket by bolting.

2. The attachment of claim 1 wherein both the front ends and the back ends of the teeth are pointed.

3. The attachment of claim 1 wherein only the front ends of the teeth are pointed.

4. The attachment of claim 1 further comprising:

a plurality of transverse rods perforating and supporting the teeth between the points of attachment of the middle transverse member and the front ends.

5. The attachment of claim 4 wherein two transverse rods perforate and support the teeth between the points of attachment of the middle transverse member and the front ends.

6. The attachment of claim 4 wherein each of the transverse rods is welded to one of the teeth at each tooth perforation.

7. The attachment of claim 4 wherein each of the transverse rods pass through spacer tubes situated between the teeth that act to space the teeth apart.

8. The attachment of claim 7 wherein each of the transverse rods is threaded on both ends to accept bolts that, when tighten, secure the rod in place.

9. The attachment of claim 1 further comprising:

at least one spacer member that is attached to the top surface of the back transverse member to space the top of the back transverse below the bottom of the bucket, thereby orienting the teeth substantially parallel with the bottom of the bucket.

10. The attachment of claim 1 wherein each bracket is substantially triangular in shape and has a rear-end attachment hole at a third extremity that aligns with a second bucket mounting hole on the bucket for mounting of the rake on the bucket by bolting.

11. The attachment of claim 1 wherein the pocket is formed by attaching an inclined transverse member to the top edge of a lower transverse member.

12. A front end loader accessory comprising:

a bucket; and

the attachment of claim 1.

13. An improved front end loader comprising:

the accessory of claim 12; and

means to manipulate the accessory.

14. An accessory for a loader, the accessory comprising:

a bucket having a back, sides and a bottom with a forward end;

a rake comprising;

a plurality of teeth oriented substantially parallel to one another in a row, each of the teeth having a front end, a middle portion and a back end, the row having two end teeth;

a back transverse member to which the back ends of the teeth are attached;

a middle transverse member to which the middle portions of the teeth are attached, the middle transverse member forming a pocket that is configured to receive the forward end of the bucket and that is attached to the forward end of the bucket; and

at least one transverse rod perforating and supporting the teeth between the points of attachment of middle transverse member and the front ends; and

two end brackets, each of the end brackets being operative to connect the rake to one of the sides of the bucket.

15. The accessory of claim 14 wherein the front ends and the back ends of the teeth are pointed.

16. The accessory of claim 14 wherein the end brackets connect the two teeth at the ends of the row to the sides of the bucket.

17. An attachment for a power-operated bucket, the bucket having a back, sides and a bottom with a forward end, the attachment comprising:

a rake comprising;

a plurality of teeth oriented substantially parallel to one another in a row, each of the teeth having a front end, a middle portion and a back end;

a back transverse member to which the back ends of the teeth are attached and which abuts said bottom when said rake is mounted on said bucket;

a middle transverse member to which the middle portions of the teeth are attached, the middle transverse member being attachable to the forward end of the bucket; and

at least one transverse rod separating and supporting the teeth between the points of attachment of the middle transverse member and the front ends; and

two end brackets for mounting of the rake on the bucket.

18. The attachment of claim 17 wherein both the forward ends and the back ends of the teeth are pointed.

19. The attachment of claim 17 further comprising:

a plurality of transverse rods perforating and supporting the teeth between the points of attachment of the middle transverse member and the front ends and at least one transverse rod supporting the teeth adjacent to the back ends.

20. The attachment of claim 19 wherein the transverse rods pass through spacer tubes situated between the teeth that act to space the teeth apart.

21. The attachment of claim 20 wherein the transverse rods are threaded on both ends to accept bolts that, when tighten, secure the rods and the spacer tubes in place.

22. An attachment for facilitating the separation of a first material from a second material with a power-operated bucket on which the attachment is mounted, the bucket having a back, sides and a bottom with a lip, the attachment comprising:

a rake comprising;

a plurality of teeth oriented substantially in a row, each of the teeth having a front end, a middle portion and a back end;

a back transverse member to which the back ends of the teeth are attached;

a middle transverse member to which the middle portions of the teeth are attached, the middle transverse member being attachable to the lip of the bucket; and

at least one transverse rod separating and supporting the teeth, said at least one transverse rod being spaced substantially forward of the lip of the bucket and being operative to prevent the first material from falling between the teeth and to allow the second material to fall between the teeth when said rake is mounted on said bucket; and

end brackets for attaching the rake to the sides of the bucket.
