Publication number: 20120228838Abstract: Apparatus and methods allow the wheels of a camera dolly to be quickly and easily changed by a single person. A dolly jack may have a leg attached to a foot and pivotable relative to the foot about a first axis. A jack rod is attached to the leg spaced apart from the first axis. An arm may be pivotally attached to the leg as desired, to provide greater mechanical advantage in lifting the camera dolly. Dolly wheels may be changed by inserting a jack rod into a receptacle on one side of the camera dolly, with the foot of the jack on the ground and with the jack leg substantially in a non-vertical position. The jack leg rotated into a second position wherein the jack leg is substantially vertical, with the dolly rolling slightly in the direction of the rotation. This lifts the side of the dolly sufficiently so that the front and back wheels, or wheel pairs, on the one side of the dolly are lifted off of the ground, allowing the wheels to be changed.Type: ApplicationFiled: March 7, 2011Publication date: September 13, 2012Inventor: Leonard T.

Publication number: 20120056142Abstract: The present invention is a vehicle lift. In particular, the present invention is directed to a vehicle lift that can be mounted to the rear of a vehicle or used as a stand-alone lift. A preferred embodiment of the lift comprises a vehicle platform mounted to two platform saddles supported by two lifting arms and two support arms. The lifting arms and support arms are pivotally attached to a mount frame at one end and the platform saddles on the other end. A spacer sleeve is attached between the lifting arms and has a lock bar inserted through it. Lift locks are attached to each end of the lock bar and can lock the lift. Two drives are attached to the mount frame at one end and to the spacer sleeve at the other end. When the platform is in a raised position, the drives are extended.Type: ApplicationFiled: September 7, 2010Publication date: March 8, 2012Inventor: Brad Christian

Patent number: 8127387Abstract: A manually held firefighting tool has an elongated staff section having a first working member at one end and a second working member at the other end. The first working member has a claw element and a spike element, each extending perpendicular to the longitudinal axis of the staff section and protruding from the staff section in opposite directions. The second working member extends from the second end of the staff section and has a U-shaped yoke element supporting an arcuate cross bar element positioned parallel to the longitudinal axis of the staff section. The second working member has its own claw element at one end and a spike element at the other end. A flat bar element is affixed perpendicularly to the cross bar element between its two ends. The firefighting tool is configured to be used in a variety of firefighting applications, allowing the firefighter to carry a single tool rather than a multitude of tools performing different functions.Type: GrantFiled: November 24, 2009Date of Patent: March 6, 2012Inventor: Daniel P. Tygh

Publication number: 20110278524Abstract: The invention is directed to a lift assembly for lowering and elevating rod holders on a fishing boat. The lift assembly includes first and second horizontal positioning beams parallel to one another. Affixed to the positioning beams are a first pivoting assembly and second pivoting assembly. The first pivoting assembly has a stationary vertical beam having a first and second end (attached to both horizontal positioning beams). A first pivoting beam attaches via a first hinge to the first end of the vertical stationary beam, while a second pivoting beam attached to the second end of the vertical stationary beam via a second hinge. The first pivoting assembly includes a second vertical beam that attaches to both distal ends of the first pivoting beam and the second pivoting beam. The lift assembly may include a power train (a hydraulic position) to lower and elevate the first and second pivoting assembly.Type: ApplicationFiled: May 12, 2010Publication date: November 17, 2011Inventor: Hector Paredes

Patent number: 8033526Abstract: A land clearing device that is sized and configured to be attached to a small earth moving machine, such as a skid loader. The land clearing device has a pusher assembly with telescopically extendable actuator arms that are operated by a control unit accessible from the interior of the earthmoving machine. When the actuator arms are extended, the forward end of the pusher assembly applies lateral force on a trunk of a tree, pushing the tree until uprooted. The pusher assembly is supported by a pair of upright legs that rest on the ground and provide stability to the pusher assembly, which cantilevered from the upright legs. A Y-shaped grabber assembly has a front hook that partially encircles and holds the tree below the location of contact with the pusher assembly. A mounting assembly is secured to the pusher assembly and the grabber assembly by a common securing rod about which the pusher assembly and the grabber assembly can pivot.Type: GrantFiled: November 3, 2009Date of Patent: October 11, 2011Inventor: Vincent A. Molino
