STUlVlP-PULLER MECHANISM.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed July 23,1906. Serial No. 327.342.

To all whom, it may concern:

Be it known that I, OSCAR A. KLErTz, a citizen of the United States, residing at Dawn, R. F. D. No. 2, in the county of Livingston and State of Missouri, have invented certain new and useful Improvements in Stump-Puller Mechanisms, of which the following is a specification, reference being had therein to the accompanying drawings.

4 This invention relates to improvements in stump-puller mechanisms, and has for its object the provision of means for facilitating the removal of stumps, trees, or the like from the earth.

V Another object of the invention is the provision of certain improvements upon the stump-puller mechanism disclosed in my Letters Patent No. 407,667, issued July 23, 1889.

lVith these and other objects in view the invention consists of certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings, Figure 1 is a perspective view of a mechanism constructed in accordance with the present invention. Fig. 2 is a top plan view of the structure depicted in Fig. 1. Fig. 3 is an enlarged detail view, in side elevation, of the adjusting device for the controlling-lever. Fig. 4 is a horizontal sectional view of the spindle with the drum removed. Fig. 5 is a fragmentary vertical sectional view of the auxiliary supportingframe, spindle, and drum. Fig. 6 is afragmentary sectional view of the drum, showing means for attaching the cable thereto. Fig. 7 is a perspective view of the inverted substantially U-shaped bracket carried by the draft-beam.

Referring to the drawings by numerals, 1 designates the primary supporting-frame, which is provided with a plurality of arms 2 2, and 3 is the auxiliary supporting-frame.

The auxiliary supporting-frame is preferably provided with four arms 4, each of which arms 4 is provided with a reinforcingrib 5. All of said arms 4 and ribs 5 are integral. The auxiliary frame 3 is integral with the vertical spindle 6. By reason of the reinforcing-ribs 5 the strength of the auxiliary frame 3 is greatly increased without pro ducing a cumbersome structure. It will be noted that the arms 4 are preferably made short as compared with the arms 2 and the width of the drum 7. The reinforced auxiliary supporting-frame 3' is secured 'to the primary supportingframe 1, preferably by any suitable fastening meansas, for instance, bolts 8.

One of the arms 4 is provided with an enlarged body portion 9, Fig. 5. The body portion 9 is provided with a hook 10, which hook 10 is provided with a curved inner surface 11. Suitable fastening means, as cable 12, is attached to the hook 10 and suitably attached to any stationary supportas, for instance, a tree-when the mechanism is in operation. However, when it is desired to haul the mechanism over the ground it is only necessary to attach the draft-animal to the hook 10.

The drum 7 is provided at its lower end with an integral horizontal ratchet-collar 13 and at its upper end with a smooth integral horizontal collar 14. The upper end of the drum 7 is provided with aplurality of ratchetteeth 15, Fig. 1, which teeth normally mesh with similarly-constructed teeth 16, formed upon the lower end of the vertically-adjustable clutch-drum 17. The hauling-cable 18 is attached to drum 7 by means of an eyebolt or staple 19, Fig. 6, the eye of which bolt 19 is seated in a socket 20, formed in the upper surface of the ratchet-collar 13. The shank of bolt 19 is passed through an aperture formed in said ratchet-collar 13, and the nut 21 is threaded upon said shank in a cut-out portion or recess 22. When the nut 21 is threaded upon the shank of the eyebolt 19 and if the cable 18 is positioned within the eye of said bolt, said cable will be clamped securely against the ratchet-collar 13 and is thereby fixedly secured to drum 7. By reason of the recess 22 and the attaching means for the cable 18 said cable is attached to said drum 7, and the attaching means does not interfere with the operation of the mechanism.

After the cable 18 (which is attached by any suitable means to the stump that is to be extracted when the mechanism is in operation) has been attached to the drum 7 and wound partly around the drum it is desirable to have the said cable automatically placed against the drum 7 above and in engagement with the first lap of the cable upon said drum. This is accomplished by my improved lug 23, which lug is formed integral with the drum per se and the ratchet-flange 13. The drum is provided with a beveled upper surface, which facilitates the adjustment of the cable 18 upon the drum as said drum is revolved for winding said cable thereon.

The clutch-drum 17 is similar in structure to the drum in my Patent No. 407,667. The bearing-block 24 is provided with an integral vertical pin 25. The pin 25 is provided with apertures, within one of which is 'a springcotter 26. The spring-cotter 26 retains the lever-plate 27 upon the bearing-block pin 25. The lever-plate 27 is secured to the controlling-lever. 28 by a plurality of fastening means, as bolts 29 29. The lever 28 is pivotally mounted upon an inverted substantially U-shaped bracket 29, which bracket is secured to draft-beam 30. The draft-beam 30 is secured by any suitable means to the horizontal supporting-arm 31, which arm 31 is integral with the clutch-drum 17.

The supporting-bracket 29, Fig. 7, is provided with an inverted-U-shaped body, and each side of said body terminates in a horizontal integral portion 32, and each portion 32 is provided with 2. depending vertical apertured extension 33. These

portions

32 and 33 constitute angular feet which overlap portions of the top and side of the draft-beam 30. Upon referring to Fig. 1 it will be noted that the portions '32 of said bracket 29 bear against the upper surface of said draft-beam 30, and the portions 23 engage the sides of 7 said beams. Any suitable meansas, for in stance, bolt 34is positioned within the apertures or portions 33 and extend transversely of the draft-beam 30 for securing said bracket in position thereon. A transverse bolt 35 extends through the sides of the bracket 29 and through the adjusting-lever 28, whereby said lever is pivotally mounted upon said bracket.

Referring particularly to Fig. 3, the means for adjusting the lever 28 upon the bracket 29 comprises a segmental gear-plate 36 and a similarly-constructed gear-plate 37. The gear-plate 36 is provided with integral horizontal lugs 38 38, which lugs are positioned against the upper and lower surfaces of the adjusting-lever 28. The lugs 38 are provided with apertures, and said adjusting-lever 28 is also provided. with apertures regisconstitutes a broad base therefor.

"or base 42 is provided with apertures, and

tering with the apertures formed in the lugs 38, whereby suitable fastening meansas, for instance, bolt 39is positioned within said registering aperture for securing said stationary gear-plate upon said lever. The gearplate 37 is pivotally mounted, as at 40, upon a substantially U-shaped bracket 41, which bracket is fixedly secured to the draftbeam 30 by means of an integral plate 42. The bracket 41 is provided with sides, one of which is integral with plate 42. The plate 42 is offset from the draft-beam 30 per se and The plate within these apertures are positioned fastening meansas, for instance, bolts 43by which the bracket 41 is secured to the draftbeam. The actuating-arm 44 is integral with the movable gear-plate 37. By vertically adjusting the arm 44 the lever 28 will be swung upon its fulcrum or bracket 29. If the arm 44 is swung downwardly toward the draft beam 30, the clutch-drum will be in an operative position with relation to the drum 7, while if said arm 44 is swung upward or away from said draft-beam the clutch-drum will be in position for placing the mechanism out of gear.

If it is desired to throw the mechanism out of operationthat is, permit the clutchdrum to be removed from in engagement with said drum 7, while the cable 18 is in a taut conditionthis may be done, because I have provided on one of the reinforced arms 4 of the auxiliary supporting-frame 3 a removable curved horizontal plate 45, carrying a spring-pressed dog 46. The plate 45 is preferably attached at its inner end to the arm 4. An aperture is formed near the outer end of said. plate 45, and a slidable bolt 47 is positioned within said aperture. The outer end of said bolt is provided with a grip-loop which not only permits the operator to grasp bolt 47, but also prevents the bolt from being displaced by any possible inward movement. The inner end of bolt 47 is fixedly secured to the dog 46, and interposed between the dog 46 and. plate 45 is a spring 48, which is carried by said bolt. While the bolt 47 may be drawn outwardly suflicient to disengage the dog 46 from the teeth of the ratchet-collar 13, it will be obvious that said dog can beentirely removed from the mechanism without removing bolt 47. However, as soon as the operator releases the bolt 47 the spring will throw the dog 46 into engagement with the teeth of the'ratchet-collar 13, and thereby prevent the drum 7 from unwinding the cable. While the mechanism is in operation and the cable is taut if it is desired to drive the draft animal or animals over said cable without any strain on said animals the mechanism may be thrown out of gear and the cable held in a taut position by reason of the locking device just described. However, the drum can be permitted to unwind by quickly disengaging the dog from the teeth of the ratchet.

Upon the enlarged body portion 9 is re movably secured a horizontal guide-plate 48, which is preferably secured to said body portion 9 by any suitable fastening meansas, for instance, vertical bolts 49. As the upper surface of the body portion 9 is formed in the same horizontal plane with the upper surface of the ratchet-collar 13, it will be readily seen upon referring to Fig. 5 that the lower face of the guide-plate 48 is positioned above the ratchet-collar 13. The function of the guideplate 48 is to prevent vertical movement of drum 7 upon the spindle 6. The head of the bolts 49 are countersunk in body portion 9 for preventing the auxiliary supporting frame to lie against the primary supportingframe 1. I

If it is desired, reference may be had to my prior Letters Patent, No. 407,667, for additional explanation.
