To at] finiront may concern Be it here1 eurer, a citizen of the United States. and a resident of lortlanth in the county of liiult noinah and State of Oregon. have invented a new and useful' Guy-linie ,lfistinerij,` of which the followingis a specification.
This invention relates more particularly to the logging industry.
in object of iny invention is `to provide au eziceedingly simple and efficient fastener for attaching` `guy lines for niasts or spurs to trees or stumps.
i1. second object is to so construct the device 'that it can readily be applied or removed without the u'astc of material or daniaug the line.
A, third object is to econoinize both in the aniouut of .help reijuired and duration of time during;` which this help must be einjiloyed. and in iii-any instances to reiilu'ee the actual loss of logging time and to do so hy siniplifvingj the operiiition of setups.
Ri. fourth object to construct the ilcvii-c that it cannot become accidentally released or inoperative. i
lifih ebiz yt is to provide a peculiar forni of clamp iihieh can he jiut in place by one man ivhile the donkey engine puts a strain on the liuc in a manner to hold the guy lino at any 'tension desired and obtained by the engine.
j These, and other objects, will be more fully-understood from the following specification as illustrated in the accon'ipanying drawing, in whit-11% Figure .lt an elevation of the upper por tion of a unisi slum" i; its relation to the lguy line.

ov linoivn that l, Ruiriotn 'LIN-- Serial No. 712,648.
Referring in detail to thedr'awing, I have illustrated. a portion 11 of the usual mast or spar to 'which is secured the end of the guy line 12. Other guy lines 13 and main lines 11 areshown attached to the mast 11 for the purpose of illustration only. a
Around the stump 15 is placed a straj 1G to one end of which is attached a tapering; anchor clamp 17 by means of the lat,n erally projecting lug- 18 in which tl e end of the line v1G isl secured, preferably l babbitting'. .nside of the clamp 17 is placed a pair of Wedgeshaped line engaging jaws 19.
One face of'each of the jaws 19 is provided.
with a line-engaging groove 20 having the rspiral groovcs-21 formed therein' to correspond with the strands of the strap 16.
l have' provided a special block 22 having a shcave 22 mounted `on 4the bolt pin 24,` which is prevented from turning hy the lug; 25, and provided with a nut 26 and an eye 2T which receives the strap 16 before it is iliade .fast around the stump. This block dii'ers from the ordinary block in that itis provided with a stop face 28 Whose function will be more fully described later.
l have provided ag'ny line clamp consisting;` of a pair of Wedge-shaped clamp meinb-ers 29 having semi-circular grooves 30 on their adjacent faces 31vv which. are also provided with spiral grooves or threads to `en- ,ojapge the rope strands. VThe 1ne1nber-29 `,lies in a wedge-shaped open-ing in the slide block which. is somewhat Ueshaped .and is provided on its sides with the dove tails 33 which. 'with the ineinber S2, fit into a U- shan'cd nuide'et. -This device is placed onthe-tigrliteningfend 35 of the line 12.
"The operation of niv' device is as follows: The stump 151s notched on its rear side to 'rf-.ecirc the Astrap 1G which is passed through the eye 27 of the block 22 'and then secured by means of the clamps 19. The guy line 12,
having;` previously been made fast to thev inast 11, is passed through the block 22 andi then hauled taut by a donkey engine; The members 29 are now placed on the tightenin; end of the line 12 and the slide block 32 and guide 34 are placed around the clan'ips 2i) hy sliding same longitudinally. By turning the `njuy line clamping device in the n'uuiner of turning; a nut it is moved,
alone; the spirally Agrooved surface of the cable until the end of the members 32 and 311 engage the face 28 of the block 22 causing the clamps 29 to be forced between the converging faces of the members 32 and 34 and .to grip the tightening end 35 in a very thorough manner.
lIt is evident that the dove-tailed structure of the member 33 will prevent the Sides of the guide 34 from spreading and the clamp from giving away or releasing the line, and that the members 32 and 34 form a very secure housing for the clamps 29. It will be seen that it 1s impossible for the parts to become accidentally separated or released, since the strain on the guy line 12 will hold the members 32 andy 34 aga-inst the face 28 of the block 22.
15 `When" desiringto remove the device it is only necessary to ull the members 32 and 34 away from the ace 28 by placing a slight additional strain'on the tightening end 35 and them driving these parts oit of the clamps 29 far enough to permit them to be line.
rotated, and the device moved away from the face 28 far enough to remove the entire i clamp: from the tightening end 35.
I am aware that many different devices v.have been' employed for attaching guy lines slidedove tailedwithin said outer guide, the
'a rope and to-be shaped members a U-shaped guide bottoms of said U-shaped members converging toward each other; and a split rope-engaging clamp consisting of a pair of grooved wedge-shaped members adapted to surround compressed when drawn into the tapered opening between said U- shaped members, the narrow end of said U- projecting beyond the ends of said clamps at all times, in combination with a block vhaving a suitable anchor strap; and a face against which the narrow end of said dove tailed clamp members can bear in a manner than when placed on the hauling end of a guy line said wedges will be forced against said guy line Without touching said block.
2. The combination of a block having a housing; a stop face on saidhousing; a
-sheave in said housing;'a guy line passing around said sheave; a split clamp on said line comprising a pair of grooved wedgeshapcd members having spiral threads formed in said groove, with a U-shaped slide receiving said clamps between its sides; and covering said clamps in said slide, said guide and slide having dove tailed engaging sides permitting same'to be slidably assembled or taken apart, the inner bottom faces of said U-shaped members having converging faces which engage said wedge-shaped clamp members, the narrow ends of said U-shape'd members projecting beyond said wedge-shaped membersat all times andy bearing against said block while said guy line is being held by 'said clamping members.
