Abstract: The present invention is a reinforced connection between a distributor body and a distributor cap. The distributor cap rests on the distributor body as in the conventional arrangements. However, an additional clamp is provided to mount over the interface between the distributor cap and distributor sandwiching the components there between. A screw/bolt passes through the clamp and through both the cap and distributor body and engages a threaded portion of the clamp. By simply tightening the screw/bolt, the cap and distributor are clamped together without inducing concentrated stresses in the distributor body. The clamp may be used in a retrofit application to strengthen the existing connection between the cap and distributor body, repair the connection in a cracked or otherwise damaged distributor, or installed as part of an original equipment design.

Abstract: A tension rod positioning apparatus and method for C-type clamps and Vises including a shaped threaded rod inserted into a shaped threaded hole on an engagement collar. When the shaped rod and shaped hole are aligned, the rod may be freely positioned within the collar. When the shaped rod is inserted into the collar and turned, the rod engages and turns the engagement collar. The engagement collar includes an external thread sized to fit an internal thread on a clamp base. In this manner, the rod may be inserted and then turned in one direction to both engage the engagement collar and increase the clamping pressure. After clamping, the shaped rod may be turned in the opposite direction to loosen the clamping pressure and disengage the engagement collar. Once the rod and collar have been disengaged by aligning the shaped rod and shaped hole of the engagement collar, the length of the rod may be freely moved within the engagement collar to reposition the clamp for the next operation.

Abstract: A multi-clamp is illustrated which operates in the manner of a traditional “c”-clamp, but which also operates cooperatively with a support such as a pipe or bar clamp to apply forces normal to otherwise difficult or impossible to reach large sheet materials. A pair of nested u-shaped members are coupled together with a threaded rod. A knob is used to actuate the threaded rod and provide motive force or actuation between the nested u-shaped members. Two alternative embodiments are also illustrated.

Abstract: A C-clamp including a two-member back with a first member telescoping from a second member to a selective position where it is releasably secured. A securing mechanism, such as a cross pin or a ratchet a pawl in a rack on the first member, releasably secures the members together at a preferred position. In the preferred embodiment, the second member comprises a channel with the first member passing into the channel. Thus, the cross pin at the channel entry end engages one of a plurality of grooves in the top of the first member. To adjust the extent of the inner member from the outer member, it rotates out of the channel to separate the pin from the selective groove, allowing the inner and out members to adjust their relative position. Equivalently, the cross pin may remove from a groove of a nonrotating inner member.

Abstract: A profile frame (1) for holding plane elements (3) in an essentially U-shaped accommodating profile (2), the one leg of the U of which is constructed as a stopping leg (4) for the plane element (3) and the other leg of the U of which is constructed essentially parallel to the stopping leg (4) as a compressing leg (5) for clamping the plane element (3) between the two legs (4, 5), is distinguished owing to the fact that the compressing leg (5) has a clamping region (5) and a nominal deformation region (7), by the deformation of which the clamping region (6) can be pressed against the plane element (3). Preferably, a clamping element (10) can be connected with the accommodating profile (2), act on the clamping region (6) of the compressing leg (5) and presses the latter against the plane element (3). The clamping element (10) can be constructed to accommodate at least one fitting (16) or can be connected with a fitting (16).

Abstract: At a crossing, rubber interface strips are positioned between the rails and the asphalt or concrete. A U-shaped spring-clip fits underneath the rail, and has upstanding arms that carry tappets, which engage the strips. One of the arms is threaded, and carries a screwed tappet-rod. Turning the tappet-rod closes the distance between the tappets, clamping the strips onto the sides of the rail, and forcing the springy arms apart. The spring-clips are manipulated into position while in an unstressed condition. The spring-clip is only brought up to force when finally assembled. Assembly can be done without tools, and with little danger of mix-assembly, or of injury to workers.

Abstract: A secure storage drawer and an installation clamp for the drawer are disclosed. The drawer is suitable for mounting to a horizontal surface without surrounding cabinetry. Suspension rails which support the slides for the drawer are so designed that when the drawer is closed there are no exposed fasteners. Tampering is thus discouraged. The drawer has a wide shallow preferably partitioned front storage area and a wide deep rear storage area which is large enough to accommodate purses or handbags. The drawer is readily retrofitted to installed furniture.
