Abstract: A pipe hanger method and apparatus wherein a bolt is threaded upwardly through a first opening within a lower arm portion of a saddle, then, in one form, through an opening in a liner, then through a larger opening in the upper arm portion of the saddle. The opening is non-cylindrical in shape. A nut is then installed on the bolt. The nut has a tapered end portion which interoperates with the shape of the opening in the upper arm of the saddle. The nut is hand-tightened and then is aligned with the opening so that the small end portion would drop into the opening. A wrench is then used on the head of the bolt to rotate the bolt for the purpose of drawing the nut and bolt together and applying a clamping force on a pipe positioned within the saddle. The liner extends along the inside of the bolt and then extends about the pipe, between it and the bight of the saddle, and then in one form extends along the inside of the upper arm portion.

Abstract: A support leg (14) is attached to a ceiling structure (10) by means of a threaded stud (12) which mates with a threaded opening (18) in an insert (16) which is swage connected to the upper end of the support leg (14). A flat bar (22) is attached to the lower end of the support leg (14) so that it extends horizontally and makes a "T" with the support leg (14). An expansion clamp assembly (28, 36, 40, 44, 46, 50, 74) is carried by the bar (22). This assembly is plugged into the tubular lower end portion (26) of the support leg (14). Wing portions (58) of a nut wing washer (50) are deflected by the insertion of the assembly into the tubular portion (26), and edges (62) of the wings (58) are biased into a tight gripping contact with the inner tubular portion (26). This secures the nut wing washer (50) and a nut ( 46) against rotation. Then, the member (22) is rotated, relative to the support leg (14), causing a relative endwise movement of a stud (28) carried by the member (22) into the nut (46).

Abstract: A wireway suspension system includes a support leg (16) attachable at an upper end to an overhead member (10) and having an elongated cross-beam member (48) perpendicularly attachable to the support leg (16). The support leg (16) has squared portions (50) at which the cross-beam (48) is mountable. The cross-beam (48) has a first portion (52) which is adjacent one side of the squared portion (50) of the support leg (16). Second and third portions (58, 59) extend outwardly and perpendicularly from the first portion (52) in directions opposite of each other. The third portion (59) which extends toward the support leg (16) is notched to receive and closely engage two opposed sides of the squared portion (50) of the support leg (16). A U-bolt (66) having two threaded end portions (68) and a substantially squared bight portion (70) closely engage three adjacent sides of the squared portion (50). The threaded end portions (68) extend through openings (72) in the first portion (52) of the cross-beam (48).

Abstract: A bolt (30) is inserted threaded end (50) first upwardly through a first opening (42) within a lower arm portion (16) of a C-shaped saddle (10), then through an opening (46) in a liner (22), then through a larger opening (46) in the upper arm portion (18) of the saddle (10). The opening (44) is hexagonal in shape. A nut (52) is then installed on the bolt (30). The nut (52) has a small end portion (54) which is hexagonal in shape. The nut (52) is hand tightened and then is aligned with the opening (44) so that the small end portion (54) would drop into the opening (44). A wrench is then used on the head (48) of the bolt (30) for rotating the bolt (30) for the purpose of drawing the nut (52) and bolt (30) together and applying a clamping force on a pipe (32) when is in the saddle (10). The liner (22) extends along the inside of the bolt (30) and then extends about the pipe (32), between it and the bight of the saddle (10), and then extends along the inside of the upper arm portion (18).

Abstract: A support leg (16) includes an insert (20) within a tubular upper portion (18). Threaded engagement is made between the threaded opening (22) in the insert (20) and a stud (14) which is welded at its upper end to an overhead structure (10). The tubular portion (18) extends through an opening in the small end (34) of a conical brace member (32). The small end (34) of member (32) is welded (38) to the member (16). A large diameter upper end (36) of brace member (32) extends axially outwardly beyond the end (42) of member (16). Rotation of member (16) relative to the stud (14) tightens the screw joint (14, 22) and forces the upper end (36) of brace member (32) into tight contact with the overhead member (10). The weld (44) is harder than the member (16), resulting in a galling of the upper end ( 42) of member (16), during the rotation. This galling makes a tight contact fit between end (42) and weld bead (44).

Abstract: A support leg (14) is attached to a ceiling structure (10) by means of a threaded stud (12) which mates with a threaded opening (18) in an insert (16) which is swage connected to the upper end of the support leg (14). A flat bar (20) is attached to the lower end of the support leg (14) so that it extends horizontally and makes a "T" with the support leg (14). An expansion clamp assembly (22) is carried by the bar (20). This assembly (22) is plugged into the tubular lower end portion (24) of the support leg (14). The uppermost part of the assembly (22) is a T-nut (48). The head (50) of the nut (48) includes a plurality of struck out barbs (76) having points (74) which penetrate into and grip the inner sidewall of the socket (24) when the assembly (22) is inserted into the socket (22). This secures the nut (48) against rotation.

Abstract: Objects (10) to be secured in place relative to a support member (48) are placed on a support portion (16) of a base member (14) which is secured to the support structure (48). A U-shaped retainer (12) is moved into a position with its sidearms (18, 20) on opposite sides of the objects (10) and the ends of the sidearms (18, 20) aligned with slots (36, 38) in the support portion (16). Then, the retainer (12) is pushed endwise, until a cross member (22), innterconnected between the upper ends of the sidearms (18, 20) is down against the objects (10). The movement of the sidearms (18, 20) causes a spreading apart of a pair of flanges (44, 46) which depend from the support portion (16) of base member (14). When the retainer (12) is seated, lower edge portions (40, 43) of the flanges (44, 46) dig into the edges (28, 30 and 32, 34) of the sidearms (18, 20), and securely connect the retainer (12) to the base member (14).

Abstract: Boiler tube studs and a method of welding the studs to boiler tubes are provided. Boiler tubes have a multiplicity of studs welded thereto and extending outwardly therefrom, with refractory material placed over the studs and held thereon to protect the boiler tubes and to prevent deterioration and wear thereof. The studs wear down over a period of time and new studs have to be welded to the tubes periodically. In accordance with the invention, the new studs are welded directly on the worn studs or nubbins without the necessity of grinding down or otherwise removing or partially removing the worn studs. The new studs have recesses in the ends to facilitate being positioned on the old studs in proper welding position and to improve the welding operation.
