Application filed February 17, 1916. Serial N 0. 8,772.. v

v To all whom it mag concern .Be it known that I JOHN EDWARD OGDEN a citizen of the United States of America, v

. clamp ng portion 12, and an insert 14. The

and a resident of Mountainville, town of Cornwall, Orange county, and Stateof-New York, have invented crtain new and useful Improvements in Cable-Clamps, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof. 3

My invention relates to devices for hanging or supportingelectric cables and wires along the'faces of walls, ceilings, fences, or other structures.

One object of my invention is to provide a device of the aforesaid character that shall be simple in construction and which may be produced in large quantities at small expense.

Another object is to provide an improved means for attaching the so-called bridle ring to the clam v Other "ob]ects and advantages of .my invention will be set forth hereinafter, and in 26 order that my invention. may be thoroughly understood 1 will now proceed to describe the same in the following specification and then point out the novel features thereof in appended claims. Referring to the drawings: Figure 1 is side elevation partly in section, of a clamp which embodies my invention, with its bridle ring attached, the wall to which the clamp is attached and the cable supported by the clamp being shown in cross-section. Fig. 2 is a rear elevation of this clamp. Fig. 3 is a longitudinal sectional elevation through the center of the clamp and the bridle ring socket. Fig. 4 is a view corresponding to to Fig. l, of a modified structure which also embodies my invention.

In Patents Nos. 1,060,014-15-16 granted to me on April 29, 1913, I haveshown and H described cable clamps of the same general l at character as that to which my present invention pertains. It has been my present aim to produce an inexpensive clamp that shall combine some of the advantages which the several clamps of my previous inventions were intended to secure.

In the carrying out of my invention, I provide an insert of non-rusting metal which is-provided with a tapped hole to receive the bridle ring and has an enlarge ment constituting a laterally extending projection or toe for the clamp.

they are not needed at first. hole in the clamp is thus exposed to the weather and the metal soon rusts in clamps- Specification of wars Patent. P tent d A 24, 1915;;

. lieferring tdFigsl, 2 and i3, the clamp comprises a sheetimetal straphaving a flat portion 10 provided with a .hole 11, a curved clamp may also be provided with a laterally bent toe 13. The insertllof non-rusting metal is formed into the clamp as clearly shown in the drawings, has an enlargement l5 constituting a projection or toe, and has a tapped hole 16 to receive a bridle ring 17 of usual form.

As shown in Fig. 4, the laterally bent toe pro ection may be omitted, the enlargement 15 of the insert performing the function alone.

'lVhen the cable line is erected it is often customary to leave off-the bridle rings as The tapped as ordinarily constructed. With the arrangerhent of my invention, however, the body of the clamp may be formed of iron or steel strap in the usual manner, but the insert which is relatively small is formed of non-rusting metal such as bronze or brass. It is consequently not damaged by exposure to the weather and is always ready for use. I

A screw such as 18, extends through the hole 11 which is intermediate the clamping, portion 12 (and consequently the bearing point of the cable in the wall), and the part 15 which forms the toe of the device and its support on the wall. This screw consequently'secures the clamp in position on the wall or surface 17 to which it is attached and affords a firm support for the cable.

The internally threaded socket is of substantial length,preferably greater than the thickness of the body portion of the clamp so that a threaded portion of ample length is provided for the reception of the threaded shank of the bridle ring.

The hanger of my present invention is adapted to receive screw threaded bridle rings of well known form, but the screw threadsof the socket are non-rusting. Consequently, I combine in a single clamp the advantages of cheapness and simplicity in construction with durahility when subjected to adverse weather conditions.-

VVhat I claim is:

L'A hanger for supporting a cable against a wall or similar surface comprising a curved body portion, adapted to partially encircle the cable, a flat portion adapted to lie parallel with the surface', and a socketinsert of non-rustable metal adapted to receive a bridle ring and having an enlargement constituting a laterally extending toe or-projection for the clamp.

'2. A han 'er for supporting acable against a wall or similar surface comprising a curved body portion, adapted to partially encircle the cable, a flat portion adapted to lie parallel with the surface, and'a laterally extending toe or projection embodying a socket insert of non-rustable metal having a tapped hole and adapted to receive a bridle ring.

3. A hanger against .a-Wall or similar surface comprising a curved body portion, adapted to partially encircle the cable, a fiat portion adapted to lie parallel with the surface, and alaterally extending toe or projection adapted to engage the Wall or, surface, and an internally threaded socket insert of greater length than the thickness of the body portion, of

nonresistible material adjacent to the toe 4 projection and adapted to receive a bridle ring, said flat portion of the clamp having a hole intermediate the curved portion of a the clamp and said toe through which a for supporting a cable screw may extend to fasten the clamp in position.

4. A hanger for supporting a cable against a wall or similar surface comprising a curved body portion, adapted to partially encircle the cable, a flat portion adaptedto. lie parallel with the surface, and a socketinsert adapted to receive a bridle ring and having an enlargement constituting a lateror projection for the In testimony whereof, I have hereunto setmyhand this 11th day of February, 1915,

in the presence of two subscribing witnesses.
