STUMP EXTRACTOR.

Application filed May 20, 1927. Serial 1 T o. 1 93,030. v

This invention relates to certainnovelimprovements in stump extractors and is particularly adapted for v the pulling of tree stumps in clearing land. The, salient: object of my invention is to provide -a stump extractor which will embody maximum flexibility in order that it may be used to pull stumps that are located in diversified positions.

. ,A further object of the invention is to provide a device of the class described which may be readily transported. v 1

A still further object of the invention is to provide a stump extractor which will be simple in constructionand efiicient in operation.

Other objects will appear hereinafter.

, The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, showing the preferred form of construction and in which: I my inven- Referring to the drawing, it may be seen that I provide an axle construction 10 on which wheels 11 and 12 are rotatably mounted. Suitably secured to the axle structure 10 as at 16 and extending therefrom are a pair of parallelly disposed

arms

14 and 15. A separating block 17 is provided between the

arms

14 and 15 adjacent the axle structure -,10 in order to separate said arms and at the.

opposite ends, the mid-point of a pull bar 18 .is mounted between the

arms

14 and 15 for pivotal movement about the fixed pivot 19 which serves to secure the pull bar 18 in position and which holds this end of the

arms

14 and 15 together. Y

An anchor structure is provided which in the present instance is comprised of cables 20 and 21 and which are secured to the arm 14 adjacent the axle structure 10. lhe cables 20 and 21 are'adapted .to be of any required length and may be secured to the structure in any desired manner, that shown being the preferred form.' In the present instance the cables 20 and 21 are provided withnooses 22 and 23; this arrangement being provided when the cables can be attached to stumps but it is to be understood that any other desired attaching means might be substituted in place of the nooses vand that the cables might be secured to any suitable fixed object other than stumps. j

sronn,

Mounted between the

arms

14 and 15 adja} o cent the axle structure 10 and positioned for turning movement is the member 24 which is secured to the hub structure 25 that protrudes through the arm 14. Extending through the g hub structure 25 is an arm 26. that is adapted to facilitate the turning of the member 24 and which is of a length sufficient to provide considerable leverage A cable 27 is secured, to the outer ends of the pull bar 18' and is as directed around the member24- Preferably :the cable 27 is looped once aroundthe member 24 so as to secure a tightor, snubbed connectionthereto. In the present instance the ends of the cable 27 are directed through holes provided in the outerendsof-thezpull bar'18,

.therebeing two or more of these holesso that the cable will be woven-back and forth-in orderto provide a snubbing efiect. v It. is apparent that movement of the arm 26 will cause '75 the pull bar 18 to pivot about the. point, 19.

Between the pivot point 19 and the ends of the pull bar 18 a'series of holes 28 are provided.

"WOven back and forth through these holes be substituted in place of said nooses.

secured to fixed objects such as the stumps are the cables 29 and 30, this woven connection producing asnubbed connection between the pull bar and saidcables 29 and 30. If desired these attaching cables may be directed to the stumps to be pulled but I have found it preferable to use the constructiondepicted in the drawing wherein the cables are securedrto a ring" such as 31. Secured to the ring 31 arecables 32 and 33which have nooses 34 and 35 at theirouter ends, it being understood that any other attaching means might The construction depicted is used when two stumps to be pulled arepositioned closed together but it is to be understood that if there is only one stump to be pulled either the noose 34 or 35 would be'secured to some fixed object and the remaining noose would be attached to the stump to be pulled. v

In operation the anchoring members are dep1cted, 111 the drawings and the cables 32 4 and 33 are attached to the stumps tobe pulled 28 'until the are in-taut position. It is in themanner described. Then the cables 29 and 3 0 are woven or laced through the holes preferable that the pull bar 18 be disposed angularly to the

arms

14 and 15 in order that a longer pull may be obtained before the adjustment of the devices are necessary. It is apparent that whenthe pull bar is disposed 110 7 ranged in this position force is exerted on the arm 26 on the side on which the pull bar 18 is at greater angularity with respect to the

arms

14 and 15. The force exerted on the arm 26 will be transmitted throughthemember 24 and the cable 27 to the pull bar 18 and thence through either the cable 29 or 30 to the ring 81, it being apparent that as soon as "a slight movement occurs the shorter of the two cables 29 and 30 will become slack. Such movement will exert tremendous force in the cables 32 and which will act to extract the stump.

While I have illustrated and described the preferred form of construction for carrying my inventioninto effect, this is capable of variation and modification, without departing from the spirit of the-invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myselfof such variations and modifications as come within the scope of the appended claims.
