INSULATOR 'GUARD Filed Oct. 8, 1926 Patented June 24, 1930 [unire STATES PATENT ofi-Fries VJOHANNESifllfllv, 0F PASING, NEAR MUNICH', GERMANY, ASSIGNOBJ T0 Gr. BROWN BOVERI & CIE., F BADEN, SWITZERLAND, A.- JOINT-STOCK COMPANY, OF SWITZER- LAND application inea october s, 192e, serial No.

This invention `relates to the protection of exposed electrical conductors and nds one application in connection with the supportv of high tension lines of electrical distribution .systems or the contact wires oi overhead traction systems.

It frequently occurs in installations where1 in strain insulators of the bar or double i ent invention is designed particularly to prevent such occurrences by presenting an obstruction to the birds perchmg on the 1nsulator or making it impossible' for them to come in Contact with both connection caps l at once.

In the drawing forming a part of this specification I illustrate various arrange ments wherein the invention may be embodied, but it is to be understood that the .Y forms here shown for illustration are notV to be regarded as exhaustive of the various embodiments which the invention may take within the scope of theappended claims.

In the drawing,

Fig. 1 is a side elevational view of an insulator equipped with one form of guard;

Fig. 2 is atransverse sectional view on the line 2-,2`of Fig. 1;-

Fig. 3 .is a side elevational view of another Vform of insulator and guard;

Fig. d. is a Asectional view on approximately line l-i of Fig. 3; n

Fig. 5 is aside elevational view of a third form of insulator and guard;

Fig. 6 is 1a sectional view on line 6-6 of Fig. 5; A

kFig'- 7 is a side elevational View of an insulator with still, another form of guard;

transversely of theV insulator showing stillY further types of guards.

Inall of the figures the reference numeral 1'0 designates an insulator, having the end caps or connection members 11 whereby it maybe joined to the electrical conductor in such fashion' that the insulator is supported in a position approximating'the horizontal. Mounted upon the insulator in proper position between the end connections 11 is a guard member; That. illustrated in Figs. 1 and 2 comprises a split ring or hoop 12 embracing the insulator andv vclamped in place bythe boltsl. This hoop carries radiallyextending barbs or prongs 13 of proper length! and arranged at proper intervals to interfere with the perchingof the birds upon them or in their vicinity on the insulator and affording an obstruction which will prevent a bird perched on one side of the guard from reaching, with its wings, the connection member 11 at the opposite side of the guard.

In the form illustrated in Figures 3 and 4 the insulator has a medial shed or umbrella flange 10, and the guard comprises a hoop 15 clamped in encircling engagement with the flange and carrying radially extending prongs 16.

In the form illustrated in Figures 5 and 6 the guard hoop carries a radially extending segmental flange 17 upon which are carried the radially extending prongs 18.

In the forms illustrated in Figures 7 and 8 the guard completely encircles the insulator, the radial members 19 supporting, at their outer ends, a spacing ring 20 which cooperates with them to constitute a screen. In the forms illustrated in Figures 9 and 1() the hoops carry wire bows 21 and 22 forming effective intercepting members extending from the insulator between its end connections.

What I claim is:

1. The combination with aline insulator having connection membersat its ends, of a hoop mounted on the insulator between the connection members and radially extending portions carried by i the -'hoop, said; radial portions extending from said hoop for such 2 Ff i i .1,766,636

distance as to prevent short circuiting of the conection members. 2. The combination with an insulator provided with connection members at the ends 5 thereof, of a s lit clamping band disposed about said Ainsu tor intermediate said members, means assoc'nted with said band for holding the same in clamped relation with respect to said insulator, and guard elements 10 carriedby Vsaid band and spaced circumferetially thereof and extending substantally radially outwardly therefrom a substantial distance from the surface of said v insulator. I Y, L 15 3. The ccm'xbination` with an insulator proy vided with connection members at the ends thereof, of a s lit clamping band disposed about. said in tor intermediate said meml j bers, means associated with saidV bandI for l n holding the same in clamped relation with s respect to said insulator, a radially-extendmsegmental flan carried by said band, an radially-exten ing guard elements se-v l cured at their respective inner ends to said 4 g5 ange and spaced circumferentiallythereof y Y and .havin their res tive outer ends disposed a su tantial 'stancerom the outer surface of said insulator. y 1 In testimony vwhereofv I have hereunto so Subscribed m name at Munich, Germany, on the 17th ay of ISieXtember, A. D. 1926.
