CLAIMS:

1 . A shovel for earth moving equipment of the type having a shovel lip and a plurality of ground engaging tool bits removably attached to said lip and characterized by:

a plurality of tool bit mounts on said shovel lip;

a plurality of tool bits releasably carried on respective said tool bit mounts, said tool bits each defining a hollow interior cavity adapted to fit over respective said tool bit mounts; a lock receiving recess in each said tool bit mount;

power operated tool bit locks received in respective said lock receiving recesses, said power operated tool bit locks incorporating a moveable lock member, and an electrical power operated drive operable to drive said lock member between two positions;

a lock receiving socket accessible within said hollow interior of each said tool bit, and oriented to register with a respective said lock receiving recess; and,

a remote control device operable to signal respective said electrical power operated drives.

2. The shovel for earth moving equipment as claimed in Claim 1 and further characterized by a drive gear rack is attached to each said moveable lock member, a drive gear connected with said gear rack, and an electrical motor coupled to said drive gear, located within said power operated tool bit lock.

3. The shovel for earth moving equipment as claimed in Claim 2 and further characterized by said power operated tool bit lock is contained entirely within the tool bit mount, and wherein said moveable lock member is moveable by remote operation of said electrical

motor and drive gear, to move said lock member into and out of engagement in said lock receiving socket in said tool bit.

4. The shovel for earth moving equipment as claimed in Claim 3 and further characterized by said tool bit mounts are fastened securely to said shovel.

5. The shovel for earth moving equipment as claimed in Claim 3 and further characterized by tooth adaptors removably attached to respective said tool bit mounts.

6. The shovel for earth moving equipment as claimed in Claim 3 and further characterized by respective teeth are mounted on respective said tool bit mounts on said shovel.

7. The shovel for earth moving equipment as claimed in Claim 3 and further characterized by lock recesses formed in respective said tool bit mounts, said lock recesses being formed in side portions of said tool bit mounts, and along axes normal to the longitudinal axis of each said tool bit mount, and wherein said lock receiving sockets are formed interiorly in each said tool bit, aligned along axes normal to the longitudinal axis of each said tool bit, and located whereby to be aligned with respective said lock recesses in said tool bit mounts when said tool bit is slid over said tool bit mount.

8. A remotely operable power operated tool lock for securing a tool bit on a tool bit mount on a ground engaging system said tool lock being concealed wholly within a tool bit mount and tool bit, and characterized by:

a lock housing body adapted to be placed in one of said tool bit, and said tool bit mount of said ground engaging system;

a lock member slideably secured in said lock housing body;

a drive transmission means connected to said lock member, operable to extend and retract said lock member relative to said lock housing body;

a wireless responsive electrical motor operable to control said drive transmission means; and,

a remote wireless controller operable to send a specific coded signal to each said tool lock, and operate its respective said wireless responsive electrical motor.

9. The power operated tool lock as claimed in Claim 8 and further characterized by said tool bit mount defines a tool bit support and a lock receiving recess, and wherein said tool bit defines a hollow interior adapted to fit over said tool bit support and a lock receiving socket accessible within said hollow interior of said tool bit, for receiving said lock member from said lock housing body.

10. The power operated tool lock as claimed in Claim 9 and further characterized by said lock member is attached to a gear rack, and including a drive gear engaged with said gear rack, said drive gear being responsive to operation of said motor for extension and retraction of said lock member relative to said lock housing body.

1 1 . The power operated tool lock as claimed in Claim 10 and further characterized by said tool bit mounts are fastened securely to said ground engaging system.

12. The power operated tool lock as claimed in Claim 1 1 and further characterized by tool bit adaptors removably attached to respective said tool bit mounts.

13. The power operated tool lock as claimed in Claim 12 and further characterized by respective tool bits are mounted on respective said tool bit mounts.

14. The power operated tool lock as claimed in Claim 12 and further characterized by respective tool bits are mounted on respective said tool bit adaptors.

15. The power operated tool lock as claimed in Claim 13 including lock recesses formed in respective said tool bit mounts, said lock recesses being formed in side portions of said tool bit mounts, and along axes normal to the longitudinal axis of each said tool bit mount, and wherein said lock receiving sockets are formed interiorly in each said tool bit aligned along axes normal to the longitudinal axis of said tool bit, and located whereby to be aligned with a respective said lock recesses in said tool bit mount when said tool is slid over said tool bit mount.

16. A method of remotely securing a tool bit on a tool bit mount on a ground

engaging shovel and characterized by:

forming said tool bit mount with an internal lock receiving recess;

forming a tool bit with a hollow interior defining a lock receiving socket;

placing a tool lock in said recess in said tool bit mount, said tool lock having a lock member, slideably secured in a lock housing body, and operable in response to an internally located electrical motor, to move said lock member, and

remotely controlling said electrical motor by means of a remote wireless controller operable to send a specific coded signal to said tool lock for operation of said electrical motor.

17. The method of remotely securing a tool bit on a tool bit mount as claimed in Claim 16 and further characterized by the steps of placing said tool bit lock in said recess in said tool bit mount, placing a tool bit defining a hollow interior over said tool bit mount and over said tool lock, said tool bit defining a hollow interior with a lock receiving socket, aligning said lock receiving socket with said tool lock housing recess in said tool bit mount, and

operating said wireless responsive motor by a remote wireless controller exterior to said tool bit mount and said tool bit.
