My invention relates to improvements in ustable fishing gafi s, and the object of my improvement is to supply for the use of fishernen and others a gait having a telescoping ndle whose entering member is constructed and adapted for frictional and releasable locking engagement with the outer member to t hole the n an adjusted position withthe hen lle,

is to be understood that other modifications may be made injthis device which will come within the protection of the appended claims.

The numeral 1 denotes a handle of hol low cylindrical shape ha *inp; the imperforate end cap 2 and an opposite centrally apertured end cap 6. On the end cap 2 may be provided a ring 3 to receive links i to which a spring snap is connected for use in suspending the device from belt of the user when desired.

The barrel or" the handle 1 is imp rtorate, and a gaff-hook 8 has a stem '4' mounted slidably and rotatably in the aperture or" the other end-cap 6.

-Gn the inner termination of said stem 7 within the barrel 1, is mounted a fr'ction device. As shown in said Fig. 1, this oomprises the following coacting elements. annular clamping ring 9 is fixed on the stem 7 spaced from its end, the later being thread- An elastic rubber element 10, longitutrally aper ured i mounted on ed. dinally cc An I "I .(i .7. es en no or the stem and secured thereon in press body 10 will frictionally engage the inner wall of the barrel somewhat but not resist the pushing or said body through the barrel longitudinally to desired distance. At this lace, the stein -o; to cause it to move through the ring nut Y to cause nut to move toward the body to further compress it against the fixed n ring 9. v This compression of the es to swell outwardly radially tightly frictionally engage the i barrel 1. so that it cannot be ongitudinally in the barrel except by I .e of more than an ordinary force. moderate degree of frictional con tact of the body 10 with the barrel suffices to hold it with the clamping rings and nut in one position to permit the threaded part 18 of the stem 7 to turn in the nut 11 in effecting" this operation. The compression of the body 10 is relaxed by turning; the stem '2' in an opposite direction, when the stem may be shifted again longitudinally in the barrel.

In Fig. 1 the body 10 is shown with its ends coned to lit the reentrant coning of the clampin rings 9 and 11. This gives these elements an effective grip upon this elastic body 10 during the compression thereof. In F 2 the coning of the clamping rings and the body 10 is reversed. with like results, but in the latter the periphery of the body 10 is larger than that shown in Fig. 1, considering like masses of the material in both. In Fig. 2, a washer 1. is shown between the clamping ring 11 and the lock nut 12.

No water, dust, sand, or sedimentary or other substances can enter the imperiorate handle of the device, so that it will be practicable to use the device in muddy Water, or

iling in the water.

3. In combination with the shaft of an instrument, a hollow handle barrel closed at one end and having an apertured opposite closel end, said shaft traversing said aper ture for both rotational and longitudinal movcn'icnts, an elastic friction-head secured upon the inner end of the shaJt to lightly contact oircumferentially with the inner wall of the barrel, said shaft termination. being threaded beyond said frictionhead, said shaft having a fixed abutment thereon, and engaging one end of the friction-head, and a clamping-nut on said threaded end engaging the friction-head to compress it against the fixed abutment when the shaft is turned one way.

4. In combination, a hollow imperforate handle, a shaft extending thereinto and having both rotational and longitudinal movements, clamping bodies, one being fixed on the shaft coaxially, the other having a central inwardly threaded aperture, the end of the shaft being threaded and the second mentioned clamping body seated for longitudinal movements on its thread, an elastic body centrally apertured to seat it on s .d shaft be tween ind end-engag d by d (jlliillplllll l cdies, said lastic boz aging the inner arts of the interposed elasinating concave or: ends to c ntch them together, when the shaft is rotated in one the elastic body is held by slight -"al. friction against the ner wall of l g Linst r tation, ane movable body is drawn toward the lined body to compress the elastic body nd it into tighter frictional. contact 1 r handle "rcninfcren'ti l to tend to ongitudnial movements f the shaft he handle due to the exercise of co upon the shaft. onv whereof I ailix m i signz tnre.
