6 Claims. 1

a The invention relates generally to clamping devices adaptable for clamping groups of cables, pipes or similar generally cylindrical articles, and while subject to more general utility, is especially intended for clamping runs of cable in ship construction.

It is well known that in present day ship construction many electric conductor cables are included in the electrical installations, and in interest of symmetry and order and efficiency, as well as safety in light of the rolling and pitching of ships at seat, it is important that the' cables be securely clamped in groups, and it is'fdesirable that clamping means be provided which will enable the making of initial and replacement installations with facility and security. It is the purpose of the present invention to provide a novel cable clamping means of the character stated.

An object of the invention is to provide a novel cable clamping means of the character stated including a base bar and means for clamping cables of selected sizes and groupings thereon without the necessity of bending, cutting and fitting parts to fit the particular cable sizes and groupings and without use of bolts, wires or the like.

In its more specific nature the invention resides in providing a clamping means of the character stated wherein are provided a base bar across which the cables are laid in selected sizes and groups, end caps engaging in clamping relation over the endmost cables and secured to the bar and including upstanding wall portions terminating in angle bent head pieces, U-shaped clamp pieces shaped to engage in clamping contact over individual intermediate cables and having' their upright wall portions terminating in angle-bent head pieces, the head pieces of adjacent'clamp pieces and end caps being associated in V-shaped cooperating pairs, and there being included channel clamp members slidable over said headpiece pairs to secure the end caps and clamp pieces in assembly and in position for clamping the cables against the bar.

Another object of the invention is to provide clamping means of the character stated inwhich there are included U-shaped gap pieces placeable between cables or cable groups to form, therebetween and including angle bent head pieces for cooperating with the other head pieces and with clamp pieces in effecting the desired unit assembly.

With the above and other objects in view-that will hereinafter appear, the nature of the inven- 2 tion will be more fully understoodby folio ing the detailed description, and appended claims and the several views illustrated in the accompanying drawings.

In the drawings- Figure 1 is a perspective view illustrating the Figure 5 is a perspective view illustrating one of the clamping members.

In the practical development of the invention the improved clamping means includes a base bar 5 across which the cables 6 of selected sizes are laid in a single group or in selective grouping as illustrated in Figure 1. An end cap member generally designated 1 is riveted or otherwisesecured as at 8 on the bar 5 at each end of the single or selective grouping of cables, and each said end cap includes a base portion 9 lying against the base bar, a, clamp body portion ill shaped to snugly engage over the adjacent endmost cable which abuts the upright main body from which curved body portion l0 extends, and

an upstanding wall portion ll terminating in an angle bent head piece l2.

A plurality of selective V-sh'aped cable caps l3 are provided and each includes a base portion [4 dimensioned and shaped to snugly engage 1 over the particular form and size of cable tob'e clamped thereby, and two parallel upright'wall portions I 5 terminating in angle bent head pieces": I6. These upright wall portions I5 are adapted to li against the similar wall portion ll of one" of the end cap members and an adjacent cable cap upright wall or another end cap upright wall, against the upright walls i5 of two similar cable caps [3, according to the nature of the particular installation, or against the upright wall of an end cap member and the upright wall of a spacer member ll when one is employed to effect a spacing of cable groups as illustrated in Figure 1.

The spacer members generally designated I! each include a base portion l8 which may or may not be secured to the base bar 5 between the groups of cables to be separated thereby, and upright wall portions l9 terminating in angle bent head pieces 20.

When the end caps 1 and cable caps i3, or the end caps I, cable caps l3 and one or more spacer members I! are assembled in cooperativerelation s 3 I in the manner hereinbefore described, the angle bent head pieces of the abutting wall portions II and I5 or II, l5 and I9 will be reversely directed so as to form V-pairs of head pieces each pair cooperating to receive channel-like clamp pieces 2| one of which is slipped over each said pair of head pieces to embrace and engage them with retaining friction effective to maintain the assembly of the clampingmeansin themanner illustrated.

It will be apparent-from the foregoing th assembly of parts herein disclosed provides simple and eficient clamping means which can be selectively assembled, without the necessity of using special tools, to clamp various arrangements or groupings of cables of like or differing sizes. a

It is to be understood that the details of con-"'' struction of the cooperating parts can be variously changed without departing from the spirit and scope of the invention, as defined in the appended i claims.
