Abstract: The invention is a tube clamp which is used to connect a first pipe to another pipe. The invention can be used, for example, to add a pipe extension to the exhaust pipe used on a car. The tube clamp is made from a plate having a first and second flat portion, each having a hole wherein said holes are equal. The holes are connected by a slot and the plate has first and second flanges surrounding and remote from the hole in the first and second portions of the plate. The plate is transversely bent between the first and second flat portion to a degree to form a connector passage, the plate being bent so that the first and second flat portions are in contact with each other and said holes are substantially coaxial with the first and second flanges directed away from each other. Connector means selected from the group of rivets or welds connects the first and second flat portions. A connector means going through a connector passage connects the pipe flange.

Abstract: A complete container includes a container frame, plus one or more modular insert structures which are removably attached to the frame to serve either as shelves, or as wall sections, as may be selected in a particular instance. The container frame includes a vertical rear wall and a pair of vertical side walls which are perpendicular to the rear wall. Each modular insert is of rectangular configuration and of such a length as to fit between the side walls of the container frame. The modular insert may be placed in a vertical plane between the front edges of the side walls in which case it serves as a wall section; or it may be placed in a horizontal plane between the side walls, in which event it acts as a shelf.Each modular insert is removably attached at its ends to the respective side walls. The attachment means are arranged in such a way as to be conveniently operated by hand, whenever the modular structure is to be inserted between the side walls or removed from them.

Abstract: A saddle shank for bicycles and similar vehicles having a tube and a mounting and abutment head fastened with the tube. A carriage is provided for securing metallic body wires of a saddle and supporting the saddle while permitting adjustment of the position of the saddle in the general axis of a bicycle with respect to the saddle shank. The saddle shank has a saddle supporting carriage, having one end mounted for pivotal abutment on the head, and another end of the carriage abutting against an adjustable stop which supports the head. The carriage is provided with indents for stable bearing of the metallic body wires and a yoke, said yoke being provided with mating indents for co-action with indents of the carriage, being mounted above the carriage.

Abstract: A fluid tight sliding clasp open ended or separable continuous fastener has two parts each comprising a row of fastening elements secured to a strip of impervious flexible material and a slider operable to close at least one end of the fastener, the elements of the two rows creating a seal against fluid pressure acting transversely of the fastener. Each part has adjacent the end to be closed additional sealing means on that face of the respective strip which, in use, forms the inside face, the additional sealing means of each part being preshaped so that when said one end of the fastener is closed they lie in edge to edge contact and are under compression whereby a fluid tight seal is obtained therebetween for resisting, in use, fluid pressure acting longitudinally of the fastener at said one end of the fastener. The fastener is particularly designed for protective suits.

Abstract: A drive mechanism for converting rotary to linear movement. A portion of a drive cable is wrapped around a drive shaft. Rotation of the shaft causes the wrapped cable portion to take up a perpendicularly extending cable portion on one end, and feed out a perpendicularly extending cable portion on the other end. As it does so, the wrapped cable portion moves axially along the drive shaft. The diameter of the drive shaft and its site of rotation determine the speed of take-up, and feed out. Axial movement of the wound portion on the drive shaft is determined either by the pitch of the threads in a threaded section on the drive shaft, or the movement of control means on an externally threaded control shaft.

Abstract: A key operated dead bolt lock includes one or a pair of standard threaded mortise cylinders. The lock further includes set screws, inaccessible from either side of a door in which the lock is installed, which prevent rotation of the cylinders. The cylinders hold cylinder collars in place to prevent access to the bolt from the side.

Abstract: An antitheft device for two-wheeled vehicles includes a U-shaped fork whose central portion is articulated on the vehicle. The two branches pivot about an axis defined by the central portion in planes substantially parallel to the longitudinal plane of symmetry of the vehicle. In a first position, ends of the branches are located near respective sides of a wheel of the vehicle. In a second position the ends are located on sides of a support member. In a third position the ends of the branches are located to the rear of the vehicle. In each of the positions, a locking member, preferably in the form of a bar removably connects the two ends. The locking member includes a key operated lock whose bolt cooperates with an orifice or bore near one end of the U-shaped fork, the orifice or bore acting as a keeper for the bolt.

Abstract: An automatically locking slider includes a locking spring for locking the slider in position on a slide fastener. The locking spring has at one end a locking prong movable into and out of a slide fastener guide channel and at the other end a first retaining portion resting on a slider body. The locking spring is further provided with a resilient tongue or tongues constituting a second retaining portion which is supported by a pivot means in a plane above and remote from the general plane of an upper body wing so as to permit the locking prong to move angularly about the pivot means.

Abstract: A table easel construction. A frame for holding and positioning a workpiece of various sizes and shapes is attached at its base to a table surface which is mounted on a base. The holding and positioning frame includes at least one vertical support attached to the rear edge of the table surface and to the upper end of the rest of the frame. The base of the holding and positioning frame may be fastened to the table surface at various positions thus enabling the angle of the workpiece relative to the table surface to be adjusted. Upper and lower clamps on the holding and positioning frame hold the workpiece above the table surface and are independently adjustable upwardly and downwardly on the frame thereby enabling the distance of the workpiece above the table to be varied and also enabling the distance between upper and lower clamps to be increased or decreased.
