wire.

A further object is to construct a guy wire guard which can be clamped on to the guy wire in such a manner that longitudinal movement of the guard is impossible.

A still further object is to construct a guy wire guard in which the securing means must be operated by a specially shaped tool so that unauthorized persons cannot tamper with the fastening means and remove the guard.

In the drawing, Fig. 1 is a side elevation of our guard showing the same attached to a guy wire.

Fig. 2 is an enlarged cross section taken on the line 2-2 of Fig. l with the guy wire removed.

Fig. 3 is a fragmental section of the guard showing the clamping member.

Fig. 4 is a ragmental view of the lower section of the guard showing the wire receiving member.

Fig. 5 is a fragmental vertical longitudinal section of our guard showing the guy wire in clamped position.

Fig. 6 is a cross section of a modified form of guard and Fig. '7 is a top plan View of one of the securing screws made use of.

In the construction of our device, we employ a guard having a lower member 8 and an upper member 9. These members are formed of sheet metal and are substantially semicircular in cross section. One end of each of these members is preferably rolled in as indicated by the nu- Ymeral 10 so as to leave a rounded upper end.

Placed in the member 8 is a block 1l which block is provided with a central groove 12. This groove may be provided with spiral grooves 13 so that when a stranded guy wire is used, the

strands will fit into these grooves and assist in holding the guard in place. The block 11 may be provided with perforated ears 14 through which rivets 16 pass. These rivets also pass through the member 8 and are for the purpose of securing the block in position.

The block 11 is also provided with outwardly extending ribs 17 which rest on the edges of the member 8 and assist in centering the block so that the groove 12 will always be in the same position; in other words, When a series of plan view of the upperl (Cl. .H9-31.5)

blocks as illustrated in Fig. 1 are placed in the fi.;

member 8, all of the grooves 12 will be in alignment. It will be noted that the block 11,

A extends upward some distance beyond the upper edges of the member 8 andthis projecting portion is provided with openings or recesses 18,

the purpose of which will be explained in detail later.

The member 9 has secured 'therein a block 19.

This block is provided with outwardly extending ribs 2O which serve the same purpose as the ribs 1'7. The block 18 is provided with a pair of extending projections 23`and with a portion 24. The portion 24 is adapted to pass over the upper surface of the block 11 while the projections 23 abut one edge of the block 11. ly illustrated in Fig. 5. The projections 23 are provided with pins or other extensions 25 which pass into the recesses 18 and thus prevent lateral'separation of the

members

8 and 9.

The block 19 is also provided on its two end faces with recesses 26 in which the inturned ends 27 of a oating lock member 28 extend. The block 19, as well as the member 9 are provided with a screw threaded bore 29 in which a set or securing screw 30 extends. provided with a polygonal recess 31 for the reception of a special tool to tighten down the screw. The block 19 may also be provided with perforated ears 32 by means oi which the block can be riveted in position.

In Fig. 6 we have shown a modiiied form of construction in which a member 83 semi-circular in cross section is employed. This member has a block 84 secured in position similar to the block 19. The block 34 is provided with a pair or ears or projections which are provided with a bore so as to receive a cotter key or pin 36. The block Se is provided with a'oating lock 37 which is similar to the lock 28 and with a screw 38 which is similar to the screw 30. It will be noted from Fig. 6 that when the securing screw 38 is tightened, the cable 89 will have a tendency to bend the cotter key 36 downwardly and thus eiectually prevent its removal by or dinary means.

We may also if found desirable form openings 40 in the member 8. These openings are for the purpose of permitting moisture which might enter the guard to 'pass therefrom instead of being This is clear- 1 yso This screw is stopped and retained in this lower member by leaving what may be termed a pit.

ber 9 is placed in position on the upper side of the wire in such a manner that the upper end ci the member 9 will be above the upper end of the member 8. When the two members are in this position, the blocks 1l and 19 will be spaced apart longitudinally. The member 9 is then moved longitudinally so that the extensions 25 will enter the recesses 18. This movement is continued until the projections 23 come in contact with one face of the blocks l1. This brings the blocks of the two sections into the position illustrated in Figs, 1 and 5i. After` this, the fastening tool is introduced into the polygonal recess 31 formed in the screw 30 and then when the screw is turned downward, the floating lock 28 is forced against the guy wire 39 so that the same will be bound tightly between this lock and the lower portion of the groove 12 formed in the block 11 thus frictionally holding the guard in place.

It will be noted from Fig. 5 that the upper end of the screw 30 is sunk a considerable distance below the surface of the member 9, thus This pit may be filled with any suitable substance so as to prevent the lodgement or retention of moisture in the pit and at the same time, such filling material will prevent anyone becoming acquainted with the particular type of opening in the screw 30 and thus prevent any tampering with the guard or loosening of the iioating lock 28.

In the modification shown in Fig. 6, the lower member 8 is dispensed with entirely and instead the cotter key or pin 36 is used. This structure has been found desirable where there is not sufficient room to place a complete guard around the guy wire as sometimes the wall of a building or an adjacent guard will interfere with or prevent the use of a second complete guard.

It will be noted from our construction that the blocks 11 and 19 are each provided with a guy wire receiving recess and furthermore, that said blocks are interlocking, that is, they interlock with each other in such a manner that lateral movement of the blocks relative to each other is prevented when the screw 30 is tightened.

It is also our intention when found desirable to eliminate the

ears

14 and 32 and spot weld the blocks 11 and 19 in place instead of riveting.
