To all whom t may coiwe'm:

Be it known that we, SAMEL H. SNUFFER and JESSE A. SHANKS, citizens of the United States, residin. at Daniels, in the county of Raleigh and bgtate of West Vir 'nia, have invented certain new and usefu Improvements in Stump-Puller and Grubbng Apparatus, of which the following is a specification, reference being had therein to the aecompanyng'drawings.

This invention relates to a stuin puller and grubloing apparatus, end the o ject of the invention is the construction of a simple and efficient apparatus for the extraction of' tree-trunks from the ground, and also for the removing of large stones or boulders from a field.

With this and other objects in view, our invention comprises certain novel combinations, constructions and arrangements of parts as will he hereinafter described, illustrated in the accompanying drawings, and more particularly pointed ont in the an pended claims.

In the drawings:

Figure, 1 is a top plan view of an apparatus constructed in accordance with our invention, while Figure 2 is a view in side elevation ol' the saine.

Figure is a perspective 'View of the lever and the yoke-frame of the apparatus.

Figure 4 is a perspective view ot one of the gripping devices, While Figure 5 is a perspective view of one of the cams ot' the gripping devices.

Figure 6 is a top plan view of another embodiment of our invention.

Figure 7 is a sectional view, taken on line 7-7, Fig. 3.

Referring to the drawiiws by numerals, 1 and 2 designate tree-truntlrs; the trunk 2 is the trunk to he extracted, or pulled, whereas trunk 1 is the anchor post, to which the apparatus is attached. A. fastening device R is around trunk l, and a fastening device e is around trunk 2; each of the fastening devices arc similarlyconstructed and comprise cables haringfloops G et their outer ends and loops 7 at their inner ends. lu loops are placed links 8. through which links S the outer ends of the cables are threaded after the cables have been placed around the stumps. in. the loops G of the fastening device around stump l. is placed a hook'9, and hook 9 hooks around the outer end of yoke-frame l0. TheV yoke-frame is formed 1n one piece and its sides l'l are spread further a art at their center than near their'ends. .["wo sleeves 12 are placed between the sides 11 to brace and-Streu 'then the yoke-frame, and extending throngV the sides l1 and the sleeves 12ers bolts or rivets 13 for securing the sleeves 12 in position.

zlhe yoke-frame 10 is laced over the inner end of lever 14, en' by means of a bolt 15, the lever is 'pivotally mounted within the vframe betvxfeen the'sleeves 12, A U-'sh'aped strap-"iron 16 is placed over the inner end of the lever 'and this `U-iron is provided with sets of anchor studs 17, u on the outer face'otthe iron. A lnk 18'is positioned 'upon the inner end of the lever 14, under theouter end of iron 16. 0n the outer end'of the lever is an auxiliary strap-iron 19, to which is secured link' 20. To link 2() is attached hauling cable 2l.

.Pulley blocks 22 and 23 are employed, and threadedthrough the pulley blocks is a cable 2 4. Pulley block 22 is attached Ato the outer end of the yoke-frame lOby suitable connecting means 25, and ulley block. 23 is comiected'tothe loop 6 oft e fastening device around stump 2, hysn'itable connectin? means 26.

)n the outer end of primary cable24 are placed similarly-constructed gripping de vices 27 and 28. Each gripping device comprises an elongated body 29 having a slot 30 therein in which the cable 24 is placed, under the pair of pivotallly mounted cams 31. An extension 32 is formed upon each body 29, and extendin longitudinally of this extension is eye-bo 13,33. A short connec'tn rod '34 is fastened at one end of the eye-bo` tgl-3 of the gripping device 27 and at its other end it is fastened to link 35, which link is adapted to be seated in the studs 17 of one pair on the strep-iron 16; by movin the link 35 to e seated position in the dierent pairs of studs, ag'reater or less leverage can be secured when drawing the cable through the pulley blocks.

A long connecting rod 36 is connected at its outer end to link 1S, and at its inner end is connected to the eye-bolt 33 of the gripping device 28. The purpose of the gripping device 27 is to grip and hold the cable while the lever is swung,r at its outer end toward the stump l, for drawing the cable through the pulley blocks and pulling or uprooting stump 2, and while the gripping deviceiglflppingf the cable, ythe fother gripping device 28, through the rod 36 shoving outwardly thereon,- villfslide -fforward upon the cable 24, toward stump 2, so that-as soon :as strain is taken oifofgripping device, 27, or possibly put the gij ping` device along the cable 24, prior to 'puf ing`- again on'the cable, the gripping device28 will take h olfl andffasten preventing lost motion 'or' backward. slipping of the cables, through the pul ley blocks22 23. A i

We have foundv by experience that we can elilciently pull or uproot stumps by using our apparatus, and can, also remove large stones or boulders from a field, as well as haul scoops of dirt out of an excavation; then, also, we can uickl remove motor vehicles from a mire con ition in a roadway, or other places.

In the embodiment shown in F ig. 6 the yoke-frame 10 is used, together with ever 14, as well as rod 34 and gripping device 27. The cable 24* is threaded throughthe gripping device 27 and is attached at its inner end to the plow-'like device 37 which includes a Ibeam 38, handles 39 and a toothed blade 40'; the toothed blade 40de adapted to be Aplaced under an obect to be moved, or removed, as at 4l otted lines), and upon drawin cncable 21 thelever will be swung outwar 1y, causing the device 37 to quickly u root, or move along over the field' an o 'ect against which the blade 40 is pressing.

JWhile we have described the preferred embodiments of our invention, and have illustrated the same in theaccompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, durm the extensive manufacture ofl the same an we,

therefore, reserve the right to make such .alterations or changes as shall fairly fall within the scope of the appended claims.
