INSULATOB-BRACKET.

Specification of Letters Patent.

Application led July 30, 1917. Serial No. 183,610.

T0 all 'ui/tom it may conce/1in.:

Be it known that I, @HARLEY C. Inns, a citizen of the United States of America, residing at Enterprise, in the county of l-locking and State of Ohio, have invented certain useful improvements in Insulator-Erackets, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention has reference generally to improvements in that class of insigned so as to be removably yet rigidly at-v tached to a cross arm by the employment of' a single fastening device.

More particularly this invention embraces the provision of anl insulator bracketwherein the construction permits of the removable clamping of the insulator wire engaging sections in position about a conducting wire.

Among the other aims and obj ects of this.

invention may be recited the provision of a device of the character described with a view to compactness, and in which the number of parts are few, the construction simple, the cost of production low and the efficiency high.

Other improvements and novel details in the construction and arrangement of the various parts of the apparatus will be ybrought out more in detail in the description to follow, which for a clear understanding of the invention should be considered in connection with the accompanying. drawings forming a part hereof, and wherein is disclosed for the purpose of illustration a convenient and satisfactory embodiment of the invention. It is to be noted in this connection that minor changes in the construction and arrangement of parts maj7 be made without departing from the principle of operation of the various parts.

The invention is clearly illustrated in the accompanying drawings in which Figure 1 is a side elevation of the invention partly in section;

Fig. 2 is a front elevation thereof;

Fig. 3 is a transverse section taken on line k3--3 of Fig. 1. j Similar characters of reference are employed in all the above described views to indicate corresponding parts. Referring now, more particularly, to the accompanying drawings, there is provided a relatively straight supporting arm 1 provided adjacent one end with spaced openings which forni a pivot 2 about which is pivotally engaged a loop 3 formed on the outer end of the horizontal portion et of an angle 5. The vertical portion 6 is provided adjacent its opposite end with an opening 7 and likewise the arm 1 is provided adj acent `its outer end with a screw opening 8 for receiving a bolt 9 the other end of which is also passed through the opening 7 until the `head strikes the outer surface of the arm 1.

"LA suitable adjusting element such as a nut 1() is adjustably engaged on the projecting Tthreaded extremity of bolt 9 and serves as a neans for clamping the arms 1 and 5 to a cross arin 11 thus holding the arms in sub- .stantially rigid yet removable position on "lthe arm 11.

7With a view toward providing an im- Aproved insulator support an arcuate insulator receiving member 12 is connected at a point intermediate its ends to the outer end of each arin 1 and 5 as indicated in the drawings. IThis arcuate or semi-circular' member terminates at one end in a lip 13 having a slot 14C therein for a purpose to be presently apparent. rlhe opposite end of each member 12 terminates in a loop 15 which is pivotally engaged in an opening 16 formed in one end of the removable arcuate or semi-circular insulator receiving member 17. A lip 18 is formed on the outer end of each removable member 17 for abutting lengagement with the adjacent lip 13 and each lip 18 is bifurcated and designed to form spaced ears 19 through which is arranged a pintle 20 for pivotally supporting and clamping the catch 21. Each of these clamping catches consists of a body 22 which serves as a finger piece one end thereof being reduced forming opposed shoulders 23 which lie upon opposite sides of the shank 24 the inner end of which terminates in an ear 25 pivotally engaged on one of the pintles 20. Of course subsequent to the swinging. of the removable member 17 to arrange the lips 13 and 18 in abutting engagement, each catch is swung about its pivot so that the shank 2li will pass through the adjacent slot le' to allow the shoulders 23 to engage beneath the adjacent lip as indicated in the drawings so as to latch the receiving members in closed position so that they are arranged in a substantially circular torni. lhe preferred insulator means used in conjunction with the insulator receiving members in the present instance consist or two substantially semiglobular sections formed desirably of glass or other insulating' material 26 haif'ing grooied surfaces 27 and flat faces 28. The flat faces are provided with transverse grooves 29 which register -with each other to form an opening when the flat `faces are arranged in abutting relation with each other for accommodating a conducting wire 30 in the manner indicated in the drawing. The outer grooved faces are provided with peripheral grooves 31 also adapted to register with each other and to be engaged by the receiving members l2 and l? in the manner indicated the drawings. T he bottoms oi the peripheral. grooves 3l are :formed with spaced recesses 32 which are engaged. by studs 33 formed on the adjacent inner faces o t the receivinei members l2 and 17.

En use the horizontal por ion llot the angle arm 5 is disposed on a cross arm in the manner indicated while the arm l is disposed opposite to the vertical portion G. The bolt is now engaged in the arms while the nut is applied to clamp the arms in a substantially rigid position. Subsequent to the arranging oi' the sections 26 about a wire they are placed so that the studs on each stationarj7 receiving member l2 engage the recesses in the adjacent section whereupon the removable receiving or clamping member is swung to engage the groove and also allow the studs to engage the adjacent recesses, and subsequent to the arrangement of the lips in abutting relation with each other the clamping catch is swung downwardly to removably clamp the sections in a substantially rigid position.

As many changes could be made in the above construction and many apparently widely different en'ibodiments of this invention could be made without departing` from the scope thereof, and it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limited sense. It is also to ber understood that the language used in the ollowing claim is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language might be said to tall therebetween.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is An insulator bracket comprising a straight arm formed at a substantially intermediate point with spaced openings and adjacent one end with an opening, an angle arm having a loop :t'oi'medat one end, said loop surrounding the stock between the spaced openings thereby providingl a pivotal connection between the straight arm and the angle arm, and a bolt passed through the opening adjacent the end or the straight arm and passing also through an opening in the angle arm, wherebythe bracket may be engaged on a cross arm, the angle arm and straight arm surrounding three sides of the cross arm and the bolt spanning the fourth side of said cross arm.

In testimony whereof l affix my signature.

@HARLEY C. ILES.
