CABLE SYSTEM.
Application filed August 10, 1925. (Serial No. 49,324.
This invention is particularly designed for use in relation to high lead logging systems. lVith such systems it is desirableto relieve the mast of as much of the side strain as possible and the present invention is directed to the mounting of the blocks at the mast in a convenient manner and one designed to relieve the mast of as much as possible of its side strain. Features and details of the invention will appear from the specification and claims. a
The invention is illustrated in the accompanying drawing wherein is shown a side elevation of the system.
1 marks the mast, 2 the guy lines of the mast, and 3 the high lead line. This lead line is carried over a sheave 4. The sheave is connected by a shackle 5 with a supporting plate 6. The supporting plate 6 is connected by a swivelled shackle 7 with a mounting 8 on the side of the mast. An .upper heel block 9 is secured to the supporting plate 6 by a shackle 10 and a heel block line 11 extends from the floating block to an anchor block 12. The anchor block is anchored through cables 13. The heel block line is carried through the usual sheaves in the blocks 9 and 12 and is carried over a pulley 14 shown in dotted lines mounted in an extension 15 on the anchor or standing block frame and over a pulley 16 shown in dottedlines on an extension 17 on the upper or floating block frame. It will be noted that when strain is put on the lead line 3 this side strain is carried directly to the heel block line so I tion with the heel block that thestrain on the mast is approximately in line with the mast. The swinging of the support 6 permits the blocks and sheaves to adjust themselves to accomplish this purpose. The extensions operating in connecprevent the twisting of the blocks. 9
That I claim as new is 1. In a cable system the combination of a mast; a high'lead line; a sheave for the high lead line over which the lead line is deflected and operated; a heel block line;
and a common swinging support for the sheave and heel block line on the mast conveying the side strain direct from the high lead line to the heel block.
'2. In a cable system, the combination of a mast; a high lead line; a sheave for the high lead'line over which the lead line is deflected and operated; a heel block line;
and a common support for the sheave and my hand. V CHESTER J. SIEFARTH.
