.uem iemembers, whennthe eerma l mreramherm ppsir' extended bar 3, and at the other end by a more or less rounded bail 4 which is adapted to be engaged with a suitable hook or other fastening member on a pole, building, or other structure,

not shown, to which the wire to be anchored is is notched out, as at I2, so as to permit the snubbing unit 5 to be swung or pivoted to a closed position, as illustrated in Figure 2, with the extension Iil and the tips of the snubbing posts or projections I resting flat upon the arm or bar 2 of the Wire frame I which is spaced from the arm of the frame on which the snubbing unit is pivotally and slidably mounted. The extension Ill thus forms with the fiatbar or base 6 of the snubbing unit 5 a longitudinally extended. slot or gap I3 at the wire-entering end of the anchor device, and thus aids in maintaining the wire to to be attached. As shown in the drawing, the frame may be made of a continuous single piece of wire or other material which is bent in any suitable manner into the form just described, withthe free ends of the wire overlapped upon each other and soldered, welded, or otherwise suitably secured together, s indicated at 2'. Instead'of overlapping the adjoining ends of the wire framethe en'ds may be butted together and and strains imposed thereon when in use to an- 1 'chora'wire such as a telephone, light or other service wire. The snubbing unit 5 is provided at one edge there'ofwith a longitudinally extended flat bar I5, and projecting laterally from one edge of the bar afi is'aplurality of equidistantly spaced snubbing posts or projections designated I which areex tended from the bar 6 so as to be of such length 'asto bridge'the gap or space between the arms -o'r bars2, 2 of the frame I, when the snubbing 'mem'bers'TaSSume a position as more particularly shown in Figure 2. The extreme opposite ends- 6f :the fiat bar 6 are bent at right angles 'tothe plane of this bar, as indicated at 8, 8, 'forming' e'ars or lugs which are suitably apertured so as to loosely receive one of the arms 2 therethrough. Thus, the snubbing unit '5 is .freely' slidable on one of the arms 2 of the wire frame I,'and' is also freely pivotal on this" arm so that the 'snubbing posts may be'swung upwardly to an open or spaced'position with respect to the other rm 2 of the wire frame I, as shown in 'Figure' 1. When in this open or upwardly shifted'position, the'wire to be anchored may be more readily and quickly engaged with the snubbing posts or projections I in an'interlaced or entwined relation thereto, as illustrated in Fig ure 1 in which the wire to be anchored is des'-' ignated 9.

-It will also be observed from the drawing that the free or outer end of the post I which is near est to the end of the anchor device at which the wire 9. enters the anchor device, is extended 1ongitudinally, as indicated at ID, in parallel relation to the fiat bar 6, and this extension III terminates in a laterally offset ear or lug I I which be anchored in amore or less central position "when it is entwined about the snubbing posts or members 1, thus minimizing likelihood of displacement of the wire from the snubbing posts during and after. the anchorage of the wire.

Atthe other end of the snubbing unit 5, the auxiliary clamping unit, 5' is arranged to positively grip the wire 9 at the point where it passes downwardly and leaves the anchor connector or drop wire tie. This auxiliary clampingmember '5' :is shown as having the form of a transversely extended fiat bar I4 provided at its opposite-ends with upwardly extended ears I5, IE ar'ranged perpendicularly tothe bar I4, and being suitably apertured to loosely receive the

arms

2, 2 of the wire frame I 'therethrough, sothat the bar M is freely slidable on the

arms

2, 2." At that end'of the'bar I4 which is slidable on the arm 2 oppositeto' the other arm 2 on which the snubbing unit 5 is pivotally and slidably mounted, the bar I4; is extended longitudinally of the arm 2, as indicated at {6, and terminates in an upwardly extended lug or ear II which is notched,as at I8, tofslid'ably receive the bar 2 therethrough. The slotted ear or' lug I! which is in spaced relation to but aligned with one of thelugs or ears I5 at the same end of the bar l4, serves to prevent the bar I4 from' becoming cocked across the Wire frame I, thereby minimizing interferencewith free sliding movement of the bar I4 towards and awayfrom the adjacent end of the snubbing unit 5. The'bar I4 serves to prevent undue spreading or constriction of the bail end of the frame I, while the'member ID with the notched out lug I I when closeddown upon'the wire frame in the position shown in Figure 2, assist the transverse baror arm 3 of the frame I in preventing-com strictionpr mashing together of the opposite sides of the frame I.

1 -When the bar I4 is moved towardsthe adjacent .endof the'snubbing unit 5 until it tightly clamps the wire 9 against the last snubbing member 'I at the point where the wire 9 leaves the'anchor connector and drops downwardly, the ear I1 which is rigidly connected with'the bar I4 en gagesbehind the post I so as to positively restrain the 'bar I4; against movement away from the 's'nubbing member 5, thereby continuously maintainingthe clamping action upon the-'wire a so long as'the'ear IT is interlocked behind the member'l, as best shown in Figures "Z-and 3. In order to effectsuch interlocking engagement, the bar I4 must be forced up tightly againstthe wire 9 before'the snubbing unit 5 is swungto its fullyclosed'position; so that the rearmostsnubbing' po'stI will move into interlocking engagementwith the; ear I I as the snubbing unit 5 approaches-its fully closed position with the tips of lall of the snubbing posts 'I restingfiat'against the" corresponding side of the wireframejl, The operation 'and'installation of the anchor connector or drop wire tie devicewill' bereadily apparent to those skilled in the art, and maybe briefiy summarized as; followsi- The anchor de vice may. becapplied to; or engaged with. a. wireat any desired point along itsglengthandwithaut interrnnting; or cutting 'the. ,wire, at the point f anchorage, by first, swinging. the, snubbing; unit the, anchor, cen-neetornbeneath; the. transverselyextendedibar e of the frame I then through the slotl-S, after which it'is alternatelypassedabout thesnubbing K posts. orxproiections; l in the mam ner: illustratedin Figure '1;- At; the. pnositeend of. the snubbingunit 5;, the-whet is; passed downs wardly between thelastysnubbing po t land the transverse-bar M, an he latterl bar is pulled-up.

swung, downwardly to a closed-position, so.- that the last snubbing post will becomeinterlocked with-the lug l1 oi the bar 14 as the snubbing unit approaches its; fully closed position, The wire is-then tightlyand; firmly, secured to the drop wire tie or anchor device, and the bail 450i theframe. I may then: besecuredi by a hook. or other suitable fastening, to a pole. or. other structure tog whichthe wirer soto be; anchored. When the wirehas. been 5 installed, the greater the strainer, the harder, the pull; on thewireathe greaterthe friction: .onthe Wire by the snubbingmembers 'l, andthe greater resistance-to rela tive pivotal movement of the: rearniost. snubbing post 1 with respect to: the, clamping bar l4, and consequently the greater resistance to slippage of the wire relative to the anchorconnectoror drop wire tie device. 'Duetothe yweightbf the wire. itself, together with. the strain thereon when it is; anchored, thereis no likelihood ofj movement of the; snubbing. unit .5- towards an open position or release ofgthe snubbing and clamping actions on they wire, and I have found that my new drop wire tie is fully: effectiveiand satisfactory under all conditions normally encountered in ordinary service, and is far superior to drop wire ties of conventional construction:

It will beobv-ious from the foregoing that the wire 9' may be quickly and easily removed-or disengaged from the drop wire tie; device by first lifting or swinging. the snubbing'unit 5 in an upward. direction to disengagethe lug l'l therefrom and permit slidinghof the-bar Mina-direction "tending. to. release the .;clamping Dressure: on the wire, after which the wire may be displaced from the snubbing members '1, all without. interruption orsevering ofrthe. wire. I

V In the case where the snubbing unit 5 and the clamping bar M are made of metal, those parts thereof which come into engagement with the wire when anchored may be suitably insulated, as by covering the parts with rubber or other insulating material, but I have found that this is not absolutely essential, since the device functions with a minimum of chafing action or other likelihood of damage to the usual insulation on the wire 9 itself. In lieu of making the parts of metal, they may be made of hard rubber, fiber, plastic, glass, porcelain, Bakelite, or other similar material of adequate strength when suitably proportioned, and which have insulating properties, although the latter are not essential. Preferably all corners of the device which come into contact with the wire 9 are rounded or smoothed so as to minimize the likelihood of dam-,

age to the wire, although even this is not absolutely essential.
