Manually operable carriage and working attachments that may be employed with the carriage

1. A manually maneuverable carriage comprising:

a frame mounted on a plurality of rotatable wheels;

a first receiver configured for receiving either a handle or a working attachment;

a second receiver configured for receiving either the handle or the working attachment;

means for selectively positioning and maintaining the first receiver at a selected rotational position relative to the frame, said means including a pin mounted on the first receiver, including a plate possessing a plurality of pin receiving spaces into one of which the pin is adapted to selectively extend, including a manually pivotable hinge to which the pin is connected, the hinge adapted to be pivotable into a first position where the pin extends into a receiving space and a second position where the pin does not extend into a receiving space, wherein the hinge is biased toward the first position and not the second position, and wherein the pin is captured within at least one slot within the first receiver and is adapted to slidably, reciprocally travel within the at least one slot.

2. The manually moveable carriage according to claim 1 wherein the working attachment comprises logging clamps.

3. A manually moveable carriage comprising:

a frame mounted on a plurality of wheels;

a first receiver configured for receiving a handle;

a second receiver configured for receiving a working implement;

means for selectively positioning and maintaining the first receiver at a selected rotational position relative to the frame, which means includes (a) a pin mounted on the first receiver, (b) a plate possessing a plurality of pin receiving spaces into one of which the pin is adapted to selectively extend, the pin receiving spaces disposed on and forming a part of the periphery of the plate and substantially equidistantly arranged in an arcuate configuration, (c) means for biasing the pin toward the pin receiving spaces, and (d) a manually pivotable hinge to which the pin is connected, the hinge adapted to be pivotable into a first position where the pin extends into a receiving space and a second position where the pin does not extend into a receiving space, wherein the hinge is biased toward the first position and not the second position, and wherein the pin is captured within at least one slot within the first receiver and is adapted to slidably, reciprocally travel within the at least one slot.

4. The manually moveable carriage according to claim 3 wherein the working attachment comprises logging clamps.

5. A manually moveable carriage comprising:

a frame mounted on a plurality of rotatable wheels;

a first receiver configured for receiving either a handle or a working attachment;

a second receiver configured for receiving either the handle or the working attachment;

means for selectively positioning and maintaining the first receiver at a selected rotational position relative to the frame; and

means for selectively positioning and maintaining the second receiver at a selected rotational position relative to the frame.

6. The manually moveable carriage according to claim 5 wherein the means for selectively positioning and maintaining the second receiver includes a pin mounted on the second receiver and includes a plate possessing a plurality of pin receiving spaces into one of which the pin is adapted to selectively extend.

7. The manually moveable carriage according to claim 6 wherein the means for selectively positioning and maintaining the second receiver includes a means for biasing the pin toward the pin receiving spaces.

8. The manually moveable carriage according to claim 6 and wherein the means for selectively positioning and maintaining the second receiver includes a manually pivotable hinge to which the pin is connected, the hinge adapted to be pivotable into a first position where the pin extends into a receiving space and a second position where the pin does not extend into a receiving space.

9. The manually moveable carriage according to claim 8 wherein the hinge is biased toward the first position and not the second position.

10. The manually moveable carriage according to claim 9 wherein the pin is captured within at least one slot within the second receiver and is adapted to slidably, reciprocally travel within the at least one slot.

11. The manually moveable carriage according to claim 5 wherein the working attachment comprises logging clamps.
