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 clamping device (400) for gripping and clamping a flat material (12) extending along a material plane (11) includes clamping jaws (402). The clamping jaws include a first clamping jaw (404) and a second clamping jaw (406) extending parallel to a clamping axis (408). The first and/or second clamping jaws are pivotable about a clamping rotational axis (410) running parallel to the clamping axis between open and closed positions. The first clamping jaw has a first clamping surface (414) and the second clamping jaw has a second clamping surface (416). The first clamping jaw has a clamping element (418) projecting relative to the first clamping surface and the second clamping jaw has a clamping recess (420) that is set back from the second clamping surface. In the closed position, the clamping recess accommodates the clamping element so that the flat material is gripped and clamped simultaneously.

The invention relates to a device for holding prosthetic teeth, the device comprising a negative form and at least one clamping unit, wherein in the negative form, recesses for holding coronal sides of the prosthetic teeth are provided, wherein the recesses are formed in such a manner that the prosthetic teeth can be inserted in an unequivocally position and orientation into the recesses, wherein the at least one clamping unit is affixable or is affixed to the negative form with a connecting means, and wherein the at least one clamping unit has at least one elastic holding means, wherein with the at least one elastic holding means, an elastic force is exercisable or is exerted from at least two different directions onto the prosthetic teeth inserted into the negative form, while the at least one clamping unit is affixed to the negative form, so that the prosthetic teeth are affixed in the device.

The invention also relates to a method for affixing, and preferably processing, prosthetic teeth and a set for implementing such a method, having several pre-fabricated prosthetic teeth and at least one such device.

A workpiece clamp device capable for changing clamp angle is arranged on a base plane and comprises a first and a second movable blocks, a driving block, at least one first and at least one second elastic members, at least one first and at least one second cylinders, and at least one third and at least one fourth elastic members. Since the first and the second cylinders are slightly rotatably and detachably respectively embedded in the first and the second embedding grooves to make the first and the second rough surfaces be exposed and the elasticity of the third and the fourth elastic members is cooperated therewith, the first and the second rough surfaces are slightly fine-tuned based on the shapes and sizes of the workpieces so as to be suitable for clamping and fastening the workpieces with different shapes.

The utility cart of the present application comprises a frame, at least two wheels and a storage panel. In one embodiment, the storage panel is removable and capable of being replaced with an alternate storage panel.

A log vice providing a partially disassembable stand alone log vice and a trailer hitch attachable log vice that have an upper support member that telescopically engages the upright member, a pair of V-shaped upper and lower vice arms with teeth attached to the outer ends of the respective upper and lower vice arms such that the vice arm teeth approach and retract from each other in accommodating the various diameter logs, and a pair of separate braces adding structural integrity to the upright member and the lower vice arm. The trailer hitch log vice also includes a hollow lower horizontal member removably attachable to a vehicle receiver hitch, while the stand alone log vice has a support stand member.

The invention relates to a fixing device for fixing workpieces and a wire erosion machine or a laser system that has a fixing device according to the invention. The present invention is supplemented by a method for wire eroding or lasing a plurality of workpieces.

The fixing device (1) serves in particular to fix workpieces (2) that are substantially rod-shaped and to be machined by wire erosion or lasing. It comprises a support apparatus (20) with a plurality of shaped elements (21) for accommodating and supporting a plurality of workpieces (2) in the correspondingly formed shaped elements (21), and for positioning and fixing the workpieces (2) in at least one translatory degree of freedom (22) in the shaped elements (21). The fixing device (1) has a clamping apparatus (50) by means of which pressure force (52) can be applied to a plurality of workpieces (2) accommodated in the shaped elements (21) so that the workpieces (2) are fixed in the clamping apparatus (50) at least in a friction lock due to the applied pressure force. The support apparatus (20) comprises a plurality of passages (30) as shaped elements (21) through which the workpieces (2) can be guided, or the support apparatus (20) comprises a plurality of first channel-shaped elements (40) as the shaped elements (21) in which the workpieces (2) can be accommodated, whereby the workpieces are blocked in their translatory degrees of freedom (22) which are oriented perpendicular to the directions of longitudinal extension (3) of the workpieces (2), or respectively also to the directions of longitudinal extension (23) of the shaped elements (21).

Disclosed generally is a face plate for a vise that is capable of gripping multiple work-pieces of different sizes at the same time. In one embodiment, the disclosed subject matter may be a vise face plate comprising: a base with an upper compensation structure and a lower compensation structure; and, wherein the upper and lower compensation structures define two sets of working surfaces. In use, the plate may be secured to a movable jaw so that the working surfaces may be employed to clamp a plurality of work pieces between the working surfaces and a fixed jaw.
