A lighting fitting for an electric luminous source having a molded part of transparent material surrounding the luminous source. The molded part is open on the top and at the bottom and has a first lower system of outer prisms and a second upper system of two outer prisms, all of them located in planes normal to the symmetry axis of the luminous source. A top part offers the luminous source a concave reflecting surface. The assembly is arranged so that a part of the luminous rays emerge directly...

A coupling for use in forming a welded tube joint is disclosed along with a method for forming such joint. A thin coupling sleeve is tightly swage-fitted onto the end of a tube to form a male or female tube end assembly suitable for engagement with a tubular mating part assembly which may be a fitting or another coupling sleeve and tube assembly. The male-female interlocking arrangement provides radial and axial alignment of the joined assemblies. The structure is arranged to provide a space bet...

This pipe fitting is formed from a pair of coupling halves which are fastened together about a continuous pipe. One of the coupling halves includes a built-in cutter assembly capable of severing the pipe into sections which are subsequently coupled together by the coupling halves. The other coupling half includes a built-in spacer assembly providing an insulated spacer block which is inserted between the ends of the separated pipe sections. The pipe sections are electrically insulated from each ...

A window fitting consisting of a metal frame attached to the wall and a metal sash with at least two glass panes attached to the frame, the sash being fitted inside the frame so that the opening of the sash is mainly congruent with the opening of the frame and with a heat insulating gasket fitted between the frame and the sash around the entire opening.

This invention is concerned with the field of sewing and more specifically relates to methods and devices for enabling women to properly fit commercial patterns without the use of tape measures or calculations.

A fitting for a drain floor having an opening toward which a plastic pipe projects comprises: A. a tubular plastic body sized for reception in said opening and having an outwardly projecting top flange to overlie the floor extent bounding the opening, an external thread below said opening at the body exterior, and a nut threadably engaging the thread and rotatable relative to the body to effect clamping of said floor extent between the top flange and nut, said body, flange, thread and nut consis...

A pipe fitting adapted to connect a section of plastic pipe to a fitting body. The fitting comprises a hollow metallic body into which is disposed a plastic sleeve. An annular ring is disposed within the sleeve. A second sleeve is disposed within the hollow body and is attached to the ring such that a socket is defined by the first and second sleeves. The socket has a transverse dimension slightly in excess of the wall thickness of the plastic pipe so that the pipe may be snugly received within ...

A pipe joint for connecting abutting ends of cast iron pipes comprising in a flexible sleeve, such as of rubber which is surrounded by one split socket, under stress, in particular out of cast iron, or a material that corresponds with its elasticity and has a resistance against corrosion that is comparable with that of the pipes to be connected.

Lashing fittings are characterized in that the rotation of the twistlock is automatically activated by vertical compression caused by the weight of a container coming into contact with the housing of the lashing fitting attached to a container or a loading platform, said twistlock being rotated by means of a force which is released exclusively by the said act of the weight of a container reacting against the housing of the lashing fitting thereby transmitting to the twistlock a revolving movemen...

An accelerometer and grease fitting is combined in a single body and has a male pipe thread fitting to thread into the threaded aperture on a machine for a normal grease fitting. In this way a combined accelerometer and grease fitting replaces a normal grease fitting without the need for providing a special mounting of the accelerometer.
