When attached to the open side of a downcomer channel, a spacer block extends between the downcomer and the doubled over portion.

Abstract: This invention provides a method for producing an internally threaded part through a stamping operation in one embodiment of which a die is provided with a curvature greater than that of the completed part. A punch is provided having ridges thereon collectively complementary in cross section to a thread to be produced and of a curvature slightly less than that of said cavity in said die, and a workpiece is engaged by said punch so as to force it against the die and form grooves in the workpiece the full depth of the thread to be produced, after which the workpiece is given a cylindrical shape, bringing the ends of the grooves into registry so as to provide an internally threaded part. Only a single stroke normally is required in forming the grooves.

Abstract: This invention provides a bracket adapted to hold cables or the like, the bracket being a unitary member that includes a longitudinally split internally threaded sleeve from one end of which is a connecting element that extends to the side edge of a flat plate having end flanges defining slots to receive a banding strap, and side flanges extending between the end flanges for providing strength and rigidity.

Abstract: This invention provides a stuffing tube for the decks and bulkheads of ships, which includes a tubular body having portions of two diameters interconnected by a tapered shoulder. An adapter having a tapered portion complementary to that of the tubular body fits inside, the adapter having a short cylindrical section dimensioned to fit over the cable. A seal comprising a strip of resilient material with an annealed wire core is wrapped around the cable and one end of it is engaged within the tapered adapter. The opposite end is engaged by a flat washer which has an inside diameter comparable to that of the cylindrical section of the adapter. A gland nut compresses the seal, pressing inwardly on the flat washer. Different cable sizes are accommodated within a single tubular body by varying the dimensions of the adapter, seal and flat washer.

Abstract: In accordance with this invention a part having an internally threaded section is formed by a progressive stamping operation in which there is only opposed rectilinear motion between the punch and die, and no mandrel is used. The part may include a U-shaped receptacle portion and a prong element for being bent over an object that is supported. In producing the part, grooves are formed in the surface of the workpiece, being progressively deepened to the depth of the screw thread and with side wall portions progressively given the inclination of the flanks of the screw threads. The threaded portion then is given a concave shape at either of its two opposite edges and a convex shape in between. The convex shape subsequently is made concave as the threaded section is closed up. In these steps the part is engaged by punch elements in the form of threaded members which have ridges corresponding to the grooves in the workpiece.

Abstract: A flanged, J-shaped bracket formed of sheet metal is provided in combination with a T-slotted downcomer (vertical channel), and creates an extremely strong support for heavy electrical cable. There is provided at the upper end of the bracket a connector element shaped generally as a hollow elbow having two portions. One such portion, the lower, is a very strong protuberance formed by making a deep recess in the web of the bracket. The underside of the protuberance seats on the bottom edge defining the T-slot, and bears large shear loads. The other such connector portion, the upper, is a tab inserted behind the upper edge defining the T-slot, and bears compression loads resulting from torque. The upper region of the protuberance fits relatively closely below the above-mentioned upper edge, thus causing the connector element to be immune to upward vibratory and other forces. The bottom surface of the protuberance is a rounded cam which greatly facilitates mounting of the bracket to the downcomer.

Abstract: This invention provides a bracket having an arcuate portion with an upper surface defined by a cylindrical segment having a flange at either edge, extending to a straight portion at one end of the arcuate portion, the straight portion having two ribs which are in part continuations of the flanges, and a flat central surface inset from the crests of the ribs. The lower edge of the central surface is spaced from and displaced to one side of the upper edge of the arcuate surface so as to provide a slot used in attaching the bracket to one form of support. Also, there is an opening through the central surface which can receive a fastening element. An L-shaped adapter with oppositely projecting lugs can be used with the bracket for attachment to a slotted supporting member.

Abstract: This invention provides an adapter for a bracket having a flat support surface with slots in it, the adapter comprising a unitary member having an arcuate surface positioned on the flat surface of the bracket with side flanges complementarily receiving the side edges of the bracket and end flanges having outer portions received in slots of the bracket. The arcuate surface of the adapter is used in supporting the load imposed on the bracket.

Abstract: This invention provides a bracket supporting arrangement in which an elongated member has sets of opposed tabs projecting from a flat surface, the upper tab in each set including a rib and a bendable end portion, the member being adapted to support a bracket having a normally vertical portion with upper and lower edges, and an opening intermediate the edges, with side flanges adapted to overlap the side flanges of the channel in providing stability to the bracket.

Abstract: This invention provides a supporting device which includes a bracket having a wall provided with two spaced slots, one edge of each slot being defined by an angular portion of the wall, and a strap, one end of which extends through one of the slots and is doubled over for attaching that end to the bracket, the opposite end having a plurality of tabs extending from one surface and having free transverse edges facing the one end of the strap. The strap at the tabs has a thickness less than the width of the slot when measured at an acute angle to the wall of the bracket, but greater than the width of the slot in a direction generaly perpendicular to the wall, so that the strap freely passes through the slot when at an angle and the transverse edges overlap the wall when the strap is more nearly perpendicular to the wall for preventing removal of the strap.
