Pivot ratcheting log dog

1. A log dog, comprising:

an elongate body having a log dog first end, a log dog second end, a front face, a back face and side faces;

a row of spaced-apart teeth coupled to the body and defining setting notches adapted to enable movement of the log dog in one direction when the log dog is releasably-locked in position during operation; and

one or more projections coupled to the body, the projections being proximate the log dog first end and protruding from the front face for engaging a log,

wherein the side faces have a slot extending from proximate the log dog first end to proximate the log dog second end and wherein the teeth extend into the slot.

2. The log dog according to claim 1 , wherein the teeth are inclined from the back face towards the front face.

3. The log dog according to claim 1 , wherein the teeth have an arcuate profile.

4. The log dog according to claim 1 , wherein the teeth slope from the back face and proximate the log dog first end to the front face and towards the log dog second end.

5. The log dog according to claim 1 , wherein the slot extends through the side faces.

6. The log dog according to claim 5 , further comprising a handle coupled proximate the log dog first end.

7. A log dog assembly, comprising:

a log dog assembly frame;

an axle coupled to the log dog assembly frame; and

a log dog, comprising:

an elongate body having a log dog first end, a log dog second end, a front face, a back face and side faces;

a row of spaced-apart teeth coupled to the body and defining setting notches; and

one or more projections coupled to the body, the projections being proximate the log dog first end and protruding from the front face for engaging a log;

wherein the side faces have a slot extending from proximate the log dog first end to proximate the log dog second end and wherein the teeth extend into the slot; and

wherein the axle engages the log dog and is operatively couplable with the row of spaced-apart teeth to enable movement of the log dog in one direction when the log dog is releasably-locked in position during operation.

8. The log dog assembly according to claim 7 , further comprising a fastener for fastening the axle to the log dog.

9. The log dog assembly according to claim 7 , further comprising a coupler for coupling the log dog assembly to a framework.

10. The log dog assembly according to claim 9 , wherein the coupler comprises:

a housing having an aperture for receiving a cross-member of the framework

and permitting slidable movement of the housing along the cross-member; and a lug coupled to the housing for releasably locking the housing to the cross-member.

11. The log dog assembly according to claim 7 , wherein the teeth are inclined from the back face towards the front face.

12. A log support and clamp assembly, comprising:

a framework, a log rest and an opposing log dog coupled to the framework, the log dog being slideably moveable towards the log rest;

the log dog comprising:

an elongate body having a log dog first end, a log dog second end, a front face, a back face and side faces;

a row of spaced-apart teeth coupled to the body and defining setting notches adapted to enable movement of the log dog in one direction when the log dog is releasably-locked in position during operation; and

one or more projections coupled to the body, the projections being proximate the log dog first end and protruding from the front face for engaging a log;

wherein the side faces have a slot extending from proximate the log dog first end to proximate the log dog second end and wherein the teeth extend into the slot.

13. The log support and clamp assembly according to claim 12 , further comprising:

a log dog assembly frame; and

an axle coupled to the log dog assembly frame;

wherein the axle engages the log dog and is operatively couplable with the row of spaced-apart teeth to enable movement of the log dog in the one direction when the log dog is releasably-locked in position during operation.

14. The log support and clamp assembly according to claim 12 , further comprising a fastener for fastening the axle to the log dog.

15. The log support and clamp assembly according to claim 13 , further comprising a coupler attached to the log dog assembly frame for coupling the log dog assembly to the framework.

16. The log support and clamp assembly according to claim 15 , wherein the coupler comprises:

a housing having an aperture for receiving a cross-member of the framework and permitting slidable movement of the housing along the cross-member; and

a lug coupled to the housing for releasably locking the housing to the cross-member.

17. The log support and clamp assembly according to claim 12 , wherein the teeth are inclined from the back face towards the front face.
