location desired whether it be in a ship, building, it

rolling stock or elsewhere.

An object of the invention is the provision of a hanger which is easily, quickly, conveniently and satisfactorily assembled for support and disposition of cables, pipes, conductors and the like, of the same or different diameter; in suitable arrangement in, ships, buildings, rolling stock and other places.

A further object of the invention is the'provision of a hanger which will securely hold cables and the like without becoming loosened due to excessive vibration in the structure to which the hanger is attached. I

The present invention has been subjected to vibration tests at the rate of 4000 strokes per minute, and has been found to remain tight after 60 minutes continuous vibration. Despite the fact that the present hanger secures the work firmly in place without loosening due to vibration, still the hanger is rapidly assembled or disassembled as the necessity arises.

The invention has for a further object a hanger which is inexpensive in cost to manufacture and is generally superior to devices now known to the inventor.

With the above mentioned and other objects in view, the invention consists in the novel and useful provision, formation, construction, association and relative arrangement of parts, members and features, all as shown in a certain embodiment in the accompanying drawing, described generally and more particularly pointed out in the claims.

In the drawing:

Fig. 1 is a front elevation of the improved hanger shown in cooperation with the work;

Fig. 2 is a plan view of a hanger bar used in the invention;

Fig. 3 is a perspective view of a clamp used in the practice of the invention;

Fig. 4 is a fragmentary, partially sectioned view of the invention taken on line 4-4 of Fig. 1, shown in cooperation with work;

Fig. 5 is a perspective view of a locking spring member used in the invention;

Fig. 6 is a side elevation, partly in section, of the locking spring shown in Fig. 5, together with an adjusting screw therefor;

Fig. 7 is a bottom plan view of the locking spring shown in Fig. 5; and

y 3 Claims. (o1. 24s cs) Fig. 8 isa modified form of screw adjustment for the locking spring.

Referring now to the drawing:

We provide a hanger bar I, formed and constructed to suitably accommodate a U-shaped strap clamp 2, of which there may be a plurality and of different sizes, which clamp is held to said hanger bar by a spring locking keeper 3. The hanger bar may take any form desired, but pref,- erably. should be of channel cross-section as best illustrated in Fig. 2. The hanger bar includes a base portion 4 and two leg portions 5 and 6. The bar includes aportion 1 upon which the work is disposed, with twoangularly bent ends 8 and 9 adapted to be secured in any convenient manner to depending supports Illand ll attached beneath the flooring or other structure vIi. In the present instance we secure the ends 8 and 9 to the members I0 and II respectively by means of bolts designated generally as l3. The :base 4, and specifically the portion I, is provided with one or more elongated slots I4. These slots are of such width as to accommodate the strap clamps 2 and provide ledge portions l5 and I6 on opposite sides of the said slots adjacent to the legs 5 and 6.

The clamp 2 may be of any form desired and of a size to best accommodate the work. In the present instance, the clamp includes two legs I! and I8 interconnected by a curved portion IS. The legs adjacent the ends are provided with transverse openings 20. In the present instance the said openings are shown as of rectangular section.

The spring locking keeper 3 includes two leaves 2| and 22 interconnected by member 23. The construction is such that the said locking spring is resilient in character and the said leaves tend to separate. Leaf 2i is provided along its marginal edges with angularly related wings or lugs 24 and 25. We preferably so arrange the said wings that they subtend an angle of 45 relative to the plane of the leaf 2|, and said wings are likewise positioned intermediate the ends of said leaves. The leaf 2| is provided in its outer end with a threaded bore 26 to accommodate a screw 21 which is fiat-ended as shown in Fig. 6 for engaging the under side of the leaf 22.

In the modification shown in Fig. 8 the leaf 22 of the spring locking keeper 3 is provided in its under side with an indentation 28 in alignment with the threaded bore 26, and a screw 29 with a pointed end 30 is threaded through said threaded bore 26 with said pointed nd of said screw received by said indentation 28 for centering said end of said screw.

The operation, uses and advantages of the invention are as follows:

Reference is made to Fig. 4, wherein a cable 3| is transversely passed over the hanger bar I and held to, hanger bar by meansof the clamp of; Fig. 3 and the, spring locking keeper of Fig. 5. When the proper sized clamp has been selected, depending upon the diameter of the work, the clamp transversely straddles the cable, with the ends of said clamp passed through one of the longitudinal slots I4 oi the han er bar and in such position that the openings 20 lie beneath the base 4 and in the zone of the, legs. 5 and B. The spring locking keeper 3 is of such length as to be transverselyaccommodated between the legs 5 and 6 of the hanger bar. The leaves of the spring locking keeper 3 are compressed together, and thelugs 24 and 25 are passed through. the openings 2]! of theclamp. The screw 21 may already be in position between the leaves, but moved outwardly so as not to interfere with compression of the leaves, whereupon the screw is turned to forcibly separate the leaves at their outermost ends, as for instance illustrated in Figs. 5. and 6. Obviously, the outermost leaf'22 will engage the base 4, resting on the ledges l5 and L5 and spanning the slot I4. As the screw 21 is turned, the lowermost leaf 2| is moved downwardly to, bring the lugs 24 and 25 into tight engagement with that portion ofthe clamp 2 bounding the openings 20 The tension of the leaf 2| or the locking spring keeper 3 holds the screw against counter-rotation, and the clamp tightly holds the work against the hanger bar. It is evident that any vibration that occurs in the structure would be communicated to the work through the hanger bar, and bythe work and hanger bar to the spring locking keeper; The net result is that vibration does not loosen the screw 21 northe locking spring from its engagement with the strap.

In Fig. 1' we have shown an embodilment Wherein a series of cables of different sizes are conveniently carried on the hanger bar.

We claim:

1., A hanger including ahanger bar upon which .work is supported, a Ues haped clamp extended over the work and through said hanger bar, said clamp being provided with openings in its ends, a spring locking keeper comprising a single piece of sheet metal bent upon itself and formed engaging said clamp for drawing said clamp upon the work and clamping the work upon said ha e b 2. A hanger as characterized by claim 1 including means for adjusting the tension of the spring leaves of the spring; locking keeper upon the work clamp.

3. A hanger as characterized by claim 1 including an adjusting screw threaded in one of the leaves of the spring locking: keeper and engaging the other leaf of said keeper for adjusting the tension of said keeper upon the work'clamp.
