Abstract: Liquid filter assemblies including an upper sample reservoir, a sample filter and a lower storage bottle are supported by a vacuum base. The base has a vacuum inlet port and, for connection to the liquid filter assembly, a vacuum outlet port. A vacuum is provided through the base to below the sample filter to draw sample liquid through the sample filter into the storage bottle. The base may include an auxiliary vacuum outlet port for connection with additional devices. The bases may be connected from one to another through auxiliary vacuum outlets and the vacuum inlets to make a chain of liquid filter assemblies supplied from one vacuum source. Alternatively, one base may include multiple vacuum outlet ports so that it may support and supply vacuum to a plurality of liquid filter assemblies.

Abstract: A portable fixture for supporting a vacuum filtration device includes a cradle portion and a clamping portion. The cradle portion supports the vacuum filtration device. The clamping portion removeably attaches the portable fixture to a support in order to secure and support the filtration device above a workspace. The portable fixture may also provide a vacuum to the filtration device. To that end, the portable fixture may have a vacuum inlet port which may be connected to a vacuum source and a vacuum outlet port that is fluidly connected to the vacuum inlet port.

Abstract: A takeout holder including a takeout jaw formed of plastic.

Abstract: A takeout jaw for handling glass bottles includes a holder for both fixed and floating inserts. This design allows an insert to be in a fixed position when the insert is provided with a nominal thickness. When a floating insert of a lesser thickness is installed, the spring clip does not engage the floating insert, which allows the floating insert to move vertically or float. The takeout holder contains either type of insert within the pocket with retaining clips that engage chamfers formed on the inserts.

Abstract: A clamp pad is provided for being selectively mounted to each jaw of a bar clamp assembly. The clamp pad can be easily mounted to the clamp jaw and radially locked in place with respect to the bar clamp assembly. In an embodiment of the invention, the clamp pad is configured to selectively be fit on either of the clamp jaws of the bar clamp assembly to facilitate assembly. The clamp pad defines a substantially increased clamping area to evenly distribute force and prevent damage to the associated workpiece. The increased dimensions of the clamp pad also stabilizes the bar clamp assembly, which eliminates tipping and thus eliminates the need for associated assemblies such as clamp saddles and the like.

Abstract: In a chuck (1) with moveable base jaws (11) inserted in radial grooves (3) in a chuck body (2) with each base jaw (11) having a releasable top jaw (21) attached to it, a joining piece (12) protruding towards the top jaw (21) is formed onto each base jaw (11) and engages in an accommodation opening (22) in the top jaw (21). Furthermore, the top jaws (21) can be clamped onto the base jaws by means of quick clamping devices (31) arranged in the top jaws (21) and the joining pieces (12). This embodiment means that the top jaws (21) of the chuck (1) can be replaced very quickly and in a simple operation, whilst a secure attachment of the top jaws (21) onto the base jaws (11) is guaranteed at all times.

Abstract: A method for attaching a jaw to a vise-like workholding apparatus. The method includes placing the jaw member onto a support member of the workholding apparatus in a first direction that is perpendicular to a worksurface of the workholding apparatus. The jaw member is placed such that at least a portion of the support member is received within a cavity in the jaw member in a first released position. The method also includes applying a first axial force in a first axial direction to the jaw member to cause the jaw member to move axially in the first axial direction to a second position wherein it is retained on the support member.

Abstract: A full face clamp pad having an engagement surface and a receiving element attached to the engagement surface, wherein the receiving element defines a closed opening that faces the engagement surface. The engagement surface and the receiving element define a second opening that faces in a direction substantially parallel to the engagement surface.

Abstract: In a two station machining vise having a stationary, center jaw and movable opposing jaws, the interior of the vise body is totally enclosed to protect the working components from machining byproducts. The vise has a brake mechanism and an offset mechanism associated with one slide so that workpieces can be engaged and released sequentially. If the brake mechanism is not activated, the two movable jaws are moved simultaneously. With the brake mechanism engaged, one movable jaw is moved to position first and then the movable jaw having the brake and offset mechanisms connected therewith is subsequently moved into position. When the workpieces are to be released, the second movable jaw is first retracted the offset distance and then the first movable jaw must be completely retracted prior to any subsequent movement by the first movable jaw.

Abstract: A removable jaw assembly for a workholding apparatus having a base that defines a worksurface and a first longitudinal axis. The assembly includes an tower portion provided on the workholding apparatus that protrudes above the worksurface and defines a second longitudinal axis that is substantially parallel to the first longitudinal axis. The assembly also includes a removable jaw member that has a cavity that is sized to receive the tower portion therein such that the jaw member may be selectively longitudinally moved on the tower portion between a released position and an attached position. The tower portion includes at least one spring-biased latch member adapted to engage an engagement area formed in a wall of the cavity at right angles to the second longitudinal axis to selectively retain the removable jaw on the tower portion.

Abstract: A top jaw assembly is adapted to be mounted on the master jaw of a chuck and includes a replaceable work holding pad. The top jaw assembly includes a top jaw formed with a first support surface lying in an axial plane and a second support surface bored concentric with the central axis of the chuck. An arcuate shape work holding pad having concentric inner and outer surfaces is provided for gripping the work piece. The outer surface is adapted to seat against the second support surface of the top jaw assembly and the inner surface is adapted to grip the work piece. Clamping means are provided which include a locking element adapted to engage the work holding pad.

Abstract: A pliers having interchangeable and replaceable jaws. Each shank of the pliers have an outwardly projecting stud formed opposite the handle end thereof. A slot is formed in the jaw end of each shank. The slot opens externally of the shank in a direction away from one another. A latch is pivotably mounted in each slot. Each latch has a finger which projects away from the pliers. Each jaw has a recess formed therein, permitting the jaw to be slidably, removably received on a stud. Each jaw further has a notch formed therein having an open end in communication with the recess in the jaw. Resilient means is positioned in each slot for constantly biasing the latch having the finger thereon outwardly of the pliers. When the jaw is slid onto a stud, the finger is received in a respective notch securing the jaw to the stud. A manually-actuatable portion of the latch permits the latch to be depressed against the biasing action of the resilient means, pivoting the finger out of the notch and releasing the jaw.
