A CORPORATION OF NEW" DROP-WIRE SUPPORT Application filed March 2, 1928. Serial No. 258,646.

Our invention relates to the telephone and telegraph art and more particularly to a drop wire support.

Our invention further relates'to articles of manufacture, combinations and sub-combinations and details of construction all of which will be more fully hereinafter described and pointedout in the claims.

In the drawings we have shown different embodiments of our invention, but it is of course to be understood that our invention is not to be confined to these particular embodiments shown by way of illustration. 7

Fig. 12 is a detail plan view of a modification.

In this art it is very important that the insulation of the drop wire should not be marred, broken or ruptured, which would damage the drop wire and lead to short-circuiting. We have, therefore, formed our drop wire support so that the insulation of the drop wire will not be injured while it is supported and clamped in our drop wire support.

' member to the tongue.

We further insure that rain, snow and sleet will not be caught and held in our drop wire support, but on the contrary, the drop wire in our support will be protected from the elements.

In Figs. 1 to 6 inclusive, our drop wire support is formed of a box 1 having sides 2 and 3, the sides 2 and 3 being provided with two or more inclined slots 44. The sides are also preferably provided with bent por- Both the box 1 and the tongue 7 are prefer- I ably made from stamped sheet metal, the inclined slots H being cut out, a portion of the blank being bent to form the sides 2 and 3 of the box, and a portion of the sides being further bent to form the bent portions 55, either at the same or a subsequent operation. We also preferably provide the interior of the box 1 with a roughened surface 8to en gage with the drop wire 9 as shown more clearly in Figs. 1, 2 and 6. r

In the form of our invention illustrated in Figs. 1 and 8, the tongue is provided with a single hole or aperture 10 to cooperate with a separate fietxible tie member 11 which may be a wire formed of copper or other'suitable material, one end 12 being threaded through the hole 10 in the tongue and thence wrapped around the tie member so as to secure the tie Theother-end 13 of the tie member 11 is passedover the support, preferably an insulatingknob 14 secured by a screw or other member 15 in a wall or other suit-able support 16. The free end of tie member 11 is passed around the groove 17 in the insulating knob 14 and then its end 13 is wrapped, one or more times, around. the tie member as shown in Fig. 13 which will secure the tie member with its tongue 7 to the insulating knob 14.

In use thebo-x 1 is placed over the drop wire 9 and then the lugs 66 upon the tongue 7 are passed through the respective bowed portions' 5-5 in the sides 2 and 3 of the box so that these lugs may ride in the inclined slots et-4 in the box. The free end of the tie member 11 is then passed around the insulating knob 14. in the manner previously described. The drop wire 9 is then, preferably, passed over the insulating knob 14 and led to its desired terminal. In some cases where, for example, the end 33 of the drop wire is short, it may be threaded through the box 1 while the tongue 7 is located within the box and before any clamping action is exerted by the lugs 6., 6 and inclined slots 4, l.

It will be clear that with the tongue 7 secured to the iixed insulating knob 1% that pressure or strain upon the drop wire 9 will cause the box 1 to move with the drop wire and cause the inclined surfaces 4 i, in the sides 2 and 3, to ride under the lugs 6-6 on the tongue and, in this manner, increase the grip of the drop wire support upon the drop wire without, however, marring in any particular the insulation of the drop wire 9.

To remove the drop wire support it is simply necessary to cause a relative movement between the box 1 and the tongue 7 to release the lugs 66 from their inclined surfaces H and bring the lugs adjacent to the bowed portions 5, when the tongue can be withdrawn and the box 1 removed from the drop wire 9. This will permit the drop wire to be again used in any other location desired, for its insulation will not be marred. By simply bending back the end 13 of the tie member this member can be released from the insulating knob ll so that our drop wire support can also be used again in any other loca tion.

Instead of having a. tongue 7 provided with a single hole for a flexible tie member,

we may provide it with two holes 1919 (F 7) and thread the end 12 of the tie member 11 through both holes, and then wrap it around the tie member as shown in 7. Or we may employ a. tie member 20 bent back upon itself to form a loop to fit over the insulating knob 14, the two ends 21-21 being bent to form hooks to hook into the holes 1919 in the tongue 7. We have shown another modification in Fig. 9 in which a tie member 22 is bent to form a loop to fit over a support, such as the insulating knob 14, its two ends 2323 being threaded through the holes 1919 and then separately wrapped around each arm of the loop.

In some locations it is not necessary to use any flexible tie member. Vi e have shown a modification of our invention in Fig. 12 in which the tongue 24: has one end 25 bent up at substantially right angles to the remaining portion and provided with a hole 26 for the reception of a nail, screw or other member such as 31 in Fig. 10.

We have shown in Figs. 10 and 11a double drop wire support 27 having a double tongue 28, (Fig. 11) with different sets of lugs 6, 6 at either end, its intermediate portion being bent at substantially right angles to form a supporting member 29 provided with a hole 30 for the reception of a screw or other securing member 31 (Fig. 10). With the double tongue 28 we employ two boxes 11 each cooperating with a different set of lugs (i6 on tongue 28 so that the drop wire 9 is clamped by both boxes 1-1 in cooperation with the respective sets of lugs 66, one set coopera 'ng with each box as shown in Fig. 10.

Having thus described this invention in connection with illustrative embodiments thereof, to the details of which we do not desire to be limited, what is claimed as new and what is desired to secure by Letters Patent is set forth in the appended claims.

What we claim is 1. In a drop wire support the combination of a slidable box provided with two sides each side being provided with inclined perforations extending entirely through the sides forming inclined slots, and with convex or bowed portions, and a tongue provided with means to pass through the convex or bowed portions to cooperate with the inclined perforated slots in the sides of the box.

2. In a drop Wire support the combination of a slidable box provided with two sides each side being provided with inclined perforations extending entirely through the sides forming inclined slots, a portion of the sides adjacent the slots being bowed or convex to form strengthening entrance passages for lugs on a tongue, and a tongue provided with lugs adapted to pass through the bowed or convex portions and cooperate with the inclined perforated slots in the sides of the box.
