A cylinder block fixture for securing a workpiece is disclosed. The cylinder block fixture includes a base and clamping members. The clamping members are positioned apart at a distance facing each other on the base. Each of the clamping members includes a support plate at one end and a hand wheel at another end. Each of the support plates comprises a shaft, support bars, and support rods facing the opposite clamping member. The support rods extend from the support bars. The shafts at the support plates receive a camshaft housing of a workpiece. The workpiece includes a cylinder block. The support rods secure the workpiece. The hand wheel rotates and causes the workpiece to rotate. The workpiece rotates to align and take reference from a main bore or a pan rail surface of the workpiece to perform machining operations on the workpiece.

A vise includes a base plate that receives a fixed jaw and a pusher jaw. The fixed jaw receiving portion of the base plate includes particular stations for receiving the fixed jaw, the particular stations defined by at least a latitudinal slot at each particular station, each latitudinal slot configured for receiving a latitudinal tab extending from the bottom of the fixed jaw. A longitudinal slot traversing a length of the fixed jaw receiving portion of the base plate may receive a longitudinal tab extending from the bottom of the fixed jaw. Double-threaded lock bolts secure the fixed jaw to the base plate once the tabs are engaged with the slots of the base plate. The pusher jaw portion of the base plate includes a worm shaft, a threaded portion of the worm shaft engaging a worm shaft mating portion milled from the bottom of the pusher jaw. The pusher jaw portion of the base plate also includes a slide bar cavity arrangement into which slide bars at the bottom of the pusher jaw slide previous to engagement of the worm shaft with the worm shaft mating portion of the pusher jaw.

A pipe clamp rotation kit preferably includes an adjustment end bracket, a pipe end bracket, an adjustment end collar, a pipe end collar and a tightening member. The adjustment end bracket includes a L-shaped bracket and a support pin. The support pin is sized to be received by an inner diameter of a support pipe of a pipe clamp. The pipe end bracket includes a pipe mounting plate and a pipe support plate. A pipe hole is formed through the pipe support plate to receive the support pipe of the pipe clamp. The adjustment end collar includes a collar base and a pair of ears. The support pipe is inserted through a bore in the collar base. A space between the pair of ears is sized to receive a lead screw of the pipe clamp. A threaded stud of the tightening member is threaded into the adjustment end collar.

A clamp release mechanism is provided. The clamp includes a body, a shaft slideably coupled to the body, a fixed jaw, and a moveable jaw coupled to the shaft. A locking component actuates between a locked position and an unlocked position. When in the locked position, the locking component biases the shaft to remain stationary with respect to the body. The clamp includes a securing component pivotally coupled to the locking component, and a biasing element that biases the securing components towards the shaft.

A mountable support and vice device for field use in small work areas includes a fastener, which is attached to a first terminus of a rod. The fastener is selectively attachable to an element of a structure, such as a scaffold, to removably attach the rod to the element of the structure. A pipe is nested around the rod so that the pipe is selectively extensible from, and selectively rotatable relative to, the rod. A coupler attached to the pipe and is positioned to selectively couple to the rod so that the pipe is fixedly positioned relative to the rod and the element of the structure. A vice is attached to the pipe proximate to a first end of the pipe and can selectively grip a substrate, such as a pipe elbow. The substrate thus is fixedly positioned and can be manipulated by a user.

A work holding device, such as a vice, includes first and second jaws and a spindle connected between them to change the distance between the jaws for holding a work piece. An elongated connection member extends from the first jaw and is shaped to fit into a receiver member of a receiver hitch on a vehicle. Adjustable projections are provided on the elongated connection member for reducing movement of the vice in the hitch. The adjustable projections may be set screws. An end cap is provided on the end of the elongated connection member. The work holding device may be mounted in a receiver member or bracket on a workbench or other work area.

A vise includes a base plate that receives a fixed jaw and a pusher jaw. The fixed jaw receiving portion of the base plate includes particular stations for receiving the fixed jaw, the particular stations defined by at least a latitudinal slot at each particular station, each latitudinal slot configured for receiving a latitudinal tab extending from the bottom of the fixed jaw. A longitudinal slot traversing a length of the fixed jaw receiving portion of the base plate may receive a longitudinal tab extending from the bottom of the fixed jaw. Double-threaded lock bolts secure the fixed jaw to the base plate once the tabs are engaged with the slots of the base plate. The pusher jaw portion of the base plate includes a worm shaft, a threaded portion of the worm shaft engaging a worm shaft mating portion milled from the bottom of the pusher jaw. The pusher jaw portion of the base plate also includes a slide bar cavity arrangement into which slide bars at the bottom of the pusher jaw slide previous to engagement of the worm shaft with the worm shaft mating portion of the pusher jaw.

A firearm maintenance aid can include a firearm vise and a firearm support device. Firearm vise can include vise jaws, a threaded rod connecting vise jaws together, and jaw pin holes in each jaw, the holes extending from an outer surface of a jaw through to an inner surface of each jaw, wherein the holes in the first jaw align with the holes in the second jaw. Firearm support device can include a clamping portion and a supporting portion. The clamping portion can be clamped between the jaws of the firearm vise, can include two parallel clamping faces, and can define vise pin holes that align with the jaw pin holes. The supporting portion can be located opposite the clamping portion and can include a cylindrical shaft. Vise pins can be received by the jaw pin holes and vise pin holes to fixedly connect the support device to the vise.

A clamp release mechanism is provided. The clamp includes a body, a shaft slideably coupled to the body, a fixed jaw, and a moveable jaw coupled to the shaft. A locking component actuates between a locked position and an unlocked position. When in the locked position, the locking component biases the shaft to remain stationary with respect to the body. The clamp includes a securing component pivotally coupled to the locking component, and a biasing element that biases the securing components towards the shaft.

The disclosure relates to a holder system for supporting sports equipment. The holder comprises a vise assembly comprising: a vise base; two moveable vise jaws provided with respective vise screw bores and guide bores, the two moveable vise jaws engageable with a first section on the sports equipment; a vise screw extending substantially horizontally through the vise base and oppositely disposing the movable vise jaws through the vise screw bores, and having two sections of threads allowing for movement of the movable vise jaws, the two sections being separated by a thread-free section; and one or more guide bars fixed in a substantially horizontal orientation in the vise base and extending through the respective guide bores.
