Application filed June 16, 1.915. Serial No. 34,449.

lo all 'whom z't may concern l clamping jaws.

Be it known that l, CHARLES Ronin, a citizen of the United States, residing at Cambridge, in the county of Isanti and State of Minnesota, have invented certain new and useful Improvements in Stump- Pullers; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the'art to which it appertains to make and use the same. A

j This invention relates to devices for pulling tree stumps out ofthe ground; and it consists. in the novel construction and combination of the parts hereinafter fully described andclairned. l

' ln the drawings, Figure 1 is a side view of stump pulling devices constructed accordingto this invention, and showing the clamp gripping the rope. F ig. 2 is a side view of the clamp, showing the jaws open. Fig. 3 is an end view of the clamp.

These devices are used by connecting them to two tree stumps 2 and -which are conveniently near together, and they are constructed so that much loss of time in adjusting the length of the pulling rope or cable l is saved. lThe pulling rope or cable e is attached at one-end to the stump 2, and its other end portion is woundnpon any suitable drum or winding mechanism which is operated in any "approved manner. A cord 6 is fastened around theother tree stump 3, and has a ring Tat its free end. A slidable clamp is provided for connecting the ring Z to the pulling rope or cable 4. j This clamp is formed of two parallel clamping jaws 8 and 9 having their adjacent edges 9 grooved so as to engage with the rope. Levers .12 are provided and are arranged in a series parallel to each other and crosswise of the These levers are pivoted to the jaw 8 by pins 14, and" to the jaw 9 by p ins l5. Bars 16 are pivoted to the projecting free end portions of the levers 12 by pins 17, and these bars have a loop' 18 at one end which engages with the ring 7.

The pulling drum or other winding naech-u anisrn is secured to any convenient anchor stump which is strong enough andwhich is not shown. The cord 6 and the pulling rope l are fastened around any two stumps which are conveniently located and which are not too large for the anchor stump. The clamp or take up is placed upon the pulling rope Jl by hand, the jaws being slid along the rope l, or the rope el being slid through the jaws, asA foundl convenient and until the partsv assume the positionsshown in Fig. l and the cord 6 is taut and the jaws are in frictionalengagement with the rope 4. The portion ofthe rope l between the clamp or take'up and the stump 2 need not be taut, and it is usually not in line with the portion of the rop-e 4 between the clamp and the pulling drum. The clamp is Aclamped on the rope 4 anywhere convenient so as to pull two selected stumps.

By the use of this device two stumps can be pulled at each pulling operationA of the drum, and much time, usually wasted in pulling in slack lpulling rope, is saved.

What I claim is:

In stump pulling devices, a pulling cable for attachment to a stump, a ring provided with means for securing it to a second stump, and a clamp comprising two parallel jaws for engaging the pulling cable, a series of levers pivoted lto the jaws and arranged crosswise of them, and a bar pivoted to the projecting free end portions of the levers and having a loop atl one epd which engages with the said'ring.

In Vtestimony whereof I have alixed my signature.

CHARLES RODN.
