Referring more particularly to the drawing, in which the same parts are designated by the same reference numerals in all of the figures,
-the invention includes generally a channel hanger bar I, a pair of brackets 2, apair of spring locks 3 for detachably locking the ends, respectively, of said hanger bar to said brackets, and clamps 4 for detachably clamping one or more cables, pipes, conductors and the like of various sizes in position on said hanger bar I.
The channel hanger bar I is formed with a base wall 5 and a pair of side Walls 6 depending from the side edges. respectively, of said base wall, and said base wall 5 is provided with a plurality of spaced parallel transverse slots l.
Each of the brackets 2 is formed with a-supporting flange B at its lowerend, extending at right angles to the bracket and in a horizontal position when the bracket is secured in a vertical position, upon which anges 8 of said brackets rest the ends, respectively, of the base wall 5 of the hanger bar I, whereby said bar is supported by said brackets upon said anges. Other supporting iianges 9 for the hanger bar I are secured on the brackets 2 above said supporting flanges 8, respectively, at suitable elevations, for supporting said hanger bar at elevations above the supporting flanges 8. The brackets 2 are welded or otherwise secured at their upper ends to the under side of the deck of a ship or to the ceiling or wall of a building, or to anyother suitable support. The flanges t and 5l` are provided with slots I0 and II, respectively, which slots extend transversely with relation to the brackets 2.
Each of the spring locks 3 comprises a single piece of resilient wire I2, preferably of steel, which wire is bent intermediate its ends at two points I3 and I 4, into an intermediate memrber I5 and a pair of spring locking arms I6 and Il extending from said bends I3 and I4,
respectively. The arm I6 is bent inwardly intermediate its ends at I8 and outwardly from said bend I8 into an outward end extension I9. The arm I'I is bent rst inwardly at 2|), then outwardly at 2I, and inwardly in the form of an elongated outwardly-bowed inward cam extension 22. The ends ofthe base wall 5 of the hanger bar I are placed upon the supporting anges 8 of the brackets 2, respectively, with slots I at the ends of said base wall 5 in register with the slots I0 in said supporting vflanges 8, respectively, and the arms I6 and l1 of two spring locks 3 are introduced through the slots 'I at the ends, respectively, of the base Wall 50i the hanger bar I and through the registering slots I0 in the supporting anges 8, respectively, upon which the ends of the hanger bar are supported, whereby the ends of the hanger bar are locked in supported position 3 on said supporting flanges 8, as shown in Fig. 3 of the drawing.
Each of the clamps 4 comprises a flexible clamp strap 23, preferably of thin steel, and a clamp locking keeper 241. The clamp strap 23 is preferably a strap of thin flexible steel, which may be wound and supplied in rolls 25 to be cut off in suitable lengths by snips, to be used in clampsl of various sizes. The clamp keeper 23 comprises a bar 26, preferably of sheet steel, bent downwardly and inwardly at a slight angle at one side into a side ange 21, from the outer edge 28 of which flange, intermediate its ends, extends a short tongue 23, on the outer end of which tongue are formed a pair of spring arms 3G, extending in opposite directions from said tongue parallel to said flange 21, theend portions of which arms are bent outwardly therefrom in the form of catches 3| for engaging the side edges of the clamp strap, in the manner and for the purpose hereinafter more-fully described.
The keeper bar 26 is provided with-a longitudinal slot 32 intermediate its ends to receive the clamp strap 23 to be locked by and between the catches 3| on the spring arms 30 of the keeper 24, in the manner and for the purpose hereinafter more fullyl described.
The operation of the invention is as follows:
The brackets 2 being secured in position at their upper ends to the underside of the deck of a ship or to a ceiling of a building, or elsewhere, a hanger bar I is placed between a pair of said brackets with the ends of the base wall 5 of said bar resting upon the supporting flanges 8 of said brackets, respectively, and with the transverse slots lat the ends of said base wall in registration with the slots I in said supporting flanges 8, respectively; the arms I6 and I1 of a spring lock 3 are compressed towards each other, and the extensions I9 and 22 of said arms, respectively, are introduced through each end slot 1 in the base member of the hanger bar I and through the slot I0 of the supporting ange 8 of each of said pair of brackets 2, as shown in Fig. 6 of the drawing, and upon pressing down each spring lock the extension I9 of the lock arm I6 is projected under the supporting flange 8 at one end of its slot I0, while the bowed cam extension 22 of the spring lock 3, engaging the adjacent end of the end slot 1 in the end ofthe base member 5 compresses the arm I1 of said lock inwardly, until the bend 2| in said arm passes through the adjacent ends of said' slot 1 of the hanger base Wall 5 and the slot I0 in the supporting flange 8, whereupon the arms I6 and I1 of the lock 3 spring outwardly until the ends of the slots 1 and Ill receive and are engaged by the bends I8 and 20 of the arms I6 and I1, respectively, of the lock 3, as shown in Fig. 3' of the drawing, thus holding the arms of said lockin the slots 1 and I0 and locking the ends of the hanger bar I to the bracket flanges 8 supported in position upon said flanges.
The cables, pipes, conductors, or'the like, indicated 33, being laid across and upon the base wall 5 of the hanger bar I, a clamp strap 23 is cut at a suitable length from the roll 25 and placed around the upper side of one or more of said cables, or the like, and the ends of said strap are extended downwardly through two of the nearest slots 1 in the hanger base wall 5; one end of said strap is bent and extended upwardly through another slot l in said base wall 5 and between the cable or the like and thestrap, or between the cable or the like and the upper sideof said hanger base wall 5; the other end of the strap 23 is then extended through the slot 32 in the bar 26 of the keeper 24, from the outer side of said bar, with the keeper 24 extended across the under side of the hanger bar I; the keeper 24 is then moved upwardly on the strap 23, which passes through the keeper slot 32, until the keeper bar 26 engages the lower edges of the side walls 8r of the hanger bar I, whereupon the keeper is turned downwardly and upwardly clockwise (Fig. 1) until the keeper ange 21, with its outer edge 28, engaging the lower edges of the side walls 6 of the hanger bar I as a pivot, is turned to an upstanding position, during which operation the strap 23, with its keeper end extending through the keeper slot 32 and bent against the inner side of the keeper bar 26, is drawn down taut against the cable or the like 33 by the keeper, the other end of the strap being held clamped between the cable and the strap, or between the cable and the hanger base wall 5, while the spring arm catches 3l are moved forwardly over the side edges of the strap 23 under spring pressure of the spring arms 30 against said strap edges, until said catchesv are sprung inwardly by said arms and snapped into engagement with the outer side of the clamp strap 23, thus locking, the clamp strap in position clamping the cables or the like 33 upon the base wall 5 of the hanger bar I in position for use.
The keeper 25 when in its locking position effectively clamps the cables and the like in position on the hanger bar and will remain securely in its locking position until it is turned out of such position by a suitable tool.
The hanger bar I- will remain locked in position on the-supporting flanges 8 of the brackets 2, until the spring locks 3 are-compressed and the arms I6 and I1- of said locks brought suiiciently close together and withdrawn from the-slots 1 and I0, respectively, in the hanger bar I and the supporting flanges 8, inthe reverse order in which said locks are introduced into said slots.
