Abstract: An articulated rafter framing jig and it's method of use and structure. It depends on the correct usage of the jig to hold securely and quickly rafter stock so that accurate marking for seat cuts, cheek and plumb cuts be made without use of complicated measurements, tools or calculations and needs only one measurement to accurately position a rafter stock in jig relative to other roof members, thereby saving time and expense.

The frame has vertical slots on opposite sides thereof for adjustably receiving a lead screw on one side of the frame and a jaw forming element on the other side of the frame. The lead screw has a headed end for use as a clamp in conjunction with a concave jaw-forming element in the oppositely disposed slot and the device is also provided with an attachable and detachable vise jaw for the clamp element on the lead screw and a further vise jaw for use in place of the concave jaw element so that ready conversion as between a vise or clamp can be effected. Both single-jaw and double-jaw workpiece holding devices are disclosed.

Abstract: A surgical leg clamp assembly for securing the thigh of a patient to an operating table for arthroscopy of the knee and arthroscopic and/or knee surgery. The surgical leg clamp consists of an elongate main frame which is universally adjustably secured to the side of an operating table and which is provided with an easily adjustable thigh-encircling snap-belt clamp assembly which is adapted to incrementally apply selective continuous clamping pressure to the thigh without resultant discomfort or damage thereto. The surgical leg clamp assembly is also adapted for selected snap-release and reapplication of the selected retentive pressure without the need for further readjustment of the surgical leg clamp assembly to reachieve the original clamping pressure.

Abstract: A vise for holding small objects. It is particularly useful as a fly tying vise. It comprises a support bearing a housing having a rotatable central arbor carried in low friction bearings. The preferred form has a hub mounted at each end of the arbor. One hub houses a clutch or other locking device. The other hub bears a clamping arrangement having fixed and moveable members with distal jaw portions adapted to hold an object such as a fishhook. The clamping arrangement has a longitudinal axis essentially parallel to but off-axis from the longitudinal axis of the arbor. The axis of the arbor does not pass through the jaws of the clamping arrangement. This permits a hook to be held in the vise with its shank lying on the axis of rotation of the arbor. In this way body thread or other dressing can be rapidly and accurately applied as the fly is created. Jaw members have essentially parallel and planar opposing faces with the maximum opening being controlled by an adjusting screw.

Abstract: A portable welding jig, for positioning and manipulating a workpiece, configured for pipe-flange welding at remote locations and capable of establishing automatically a two-holed flange configuration, is comprised of a rotatable shaft adjustably secured to a support, wherein the shaft rotates about a longitudinal work axis, and an adjustment member for orienting the shaft in a positioning plane containing the work axis; a flange mounting member depending from the distal end of the shaft, including a flange mounting plate member for receiving a flange and presenting same for rotation about the work axis in a working plane generally normal to the positioning plane; and indexing members for locating a flange borne upon the mounting plate in a two-holed configuration within the plane.

Abstract: A support member (2), on which the object is intended to rest, and a base member (1) which carries the support member. The base member (1) consists mainly of a fixed frame (6) and an expanding column (9) hinged to the frame which carries the support member (2). The column by expansion or contraction can raise or lower the support member. Between the frame and the column is attached a control contrivance (13) for positioning the column between different swing positions. At a lower end position, in which the support-member is to a high degree obliquely positioned, the member can connect with a unit at a lower level, from which the workpiece can be lifted to a desired higher level. The support member also has elements (28) to ensure that the workpiece is held securely in position in all support-member attitudes.

Abstract: An adjustable jig assembly for holding a work piece in a desired position, comprising a stand having wall members defining a pair of opposed substantially vertically extending slide channels, mounting means slidable in the slide channels for fixedly mounting therebetween an axially rotatable retaining means in desired vertical and axial orientation, and a work piece engaging member adapted to be fixedly retained by the retaining means in desired orientation about an axis normal to that of the axially rotatable retaining means. The adjustable jig assembly is particularly useful in manufacturing replacement flanged pipes due to the criticality of reproducing the exact spatial orientation of the flange members. Present practice requires that individual jigs be custom made for each flange and that the individual jigs be identifiably coded so that they can be reused during a stress relieving treatment subsequent to welding and machining operations.

Abstract: An apparatus for holding a workpiece is provided which will allow rotation of the workpiece within the apparatus. A generally stationary base (78) supports a rotatable assembly which includes a pair of outer rings (62,62'), at least one inner hoop (64,64') positioned within each ring, and means (42,112) for securing the workpiece substantially within the assembly are included in the apparatus. Bearing mechanisms (94,94') on the base (78) engage portions of a respective outer ring to allow rotative movement of the assembly about an axis (52). Preferably the base is provided with means (84) for adjusting the distance between the outer rings (62,62') along the axis (52). Means (101) for preventing the rotation of the assembly and workpiece may also be provided.

Abstract: Large, spherically preshaped, thin workpieces are held and clamped in discrete, well-defined points under utilization of holding and clamping elements in which a portion of a head is universally pivotable about a point being the center of a sealing rim for a plenum chamber adjacent the engaging workpiece in which plenum chamber high pressure is established so that the workpiece can slide above the rim on an air cushion while it is being held through application of below-atmospheric suction pressure in the plenum.
