JOHN K. FLYNN, SUPERIOR. WISCONSIN.

STUMP-P'ULLER.

' Application filed June 29,

To all whom it may concern Be it known that 1, JOHN K. FLYNN, a citizen of the United States residing at Superior, in the county of Douglas and State of Wisconsin. have invented certain new and useful Improvements in Stump-Pullers, of which the following is a specification.

This invention relates to stump pullers, particularly to those of the Windlass type, and has for its object the provision of a double drum windlass having associated therewith a cable adapted to be engaged about a stump to be extracted, both of the drums of the windlass'structure being positively driven and the rope taken in by the drum structure's being released therefrom and dropped onto the ground, an arrangement having the advantage of permitting any desired length of cable to be used.

An im'portant'obj'ect is the provision of a device of this character which is sweep actuated and which will therefore be very powerful, means being associated with the driving head whereby the apparatus, may be thrown out of gear and rendered idle.

Another object is the provision of a device ofthis character having novel dog actuated means for effecting rotation of the drums and other dog means for preventing retrograde" movement of the drums until such is desired.

An additional object is the provision of a device of this character which will be comparatively simple and inexpensive in manufacture. highlyeiiicicnt in use. durable in service. and a general improvement in the m." i r With the above and other objects and advantagesfin view, the invention consists in the details of construction to be hereinafter more fully describedand claimed and illustrated in the accompanying drawings in which- Figure 1 is a plan view of my device,

Fig. 2 is a vertical longitudinal sectional view, and

r Fig. 3 is a rear end elevation.

Referring more particularly to the drawings. the numeral 10 designates the base portion of the device which is preferably formed as a casting and which is formed at spaced points with bearings 11, 12 and 13. This base portion is bolted onto heavy timbers 14 which may be anchored upon the ground at the desired location by any ordinary means. Formed on one end of this base is a book 15 Specification of Letters Eaten t.

with which an anchoring cable may be engaged. The numeral 16 designates the top plate of the supporting frame which is similar t the bottom plate and which is bolted onto uprights 17 rising from the bottom plate. This top plate 16 is formed with bearings 18 and 19 which aline with the bearings 11 and 13, respectively. The top plate is also formed with a bearing 20 in axial alinement with but greatly larger than the bearing 12.

Located within opposite ends of the frame thus formed are drums 21 and 22 each of which is formed with trunnions 23 revolubly engaged within the bearings 11 and 18 and 13 and 19. These drums are similar in construction and are preferably formed hollow for the sake of lightness and each is formed in its periphery with a plurality of circumferential grooves 241- within which a cable to be hereinafter described, is adapted to be engaged. The drums have their upper portions toothed to form gears 25and 26.

Engaged in the bearing 12 is a vertical shaft 27 carrying a collar 28 upon which rests a gear 29 disposedbetwee'n and meshing with the gears 25 and 26. Carried by the upper face of, this gear 29 are'clutch elements" 30 with which'co'ciperate clutch elements 31 carried by the member 32 rotatable within the bearing 20 and carried by the short shaft 33. Mounted-above the bearing 20 is a driving head 34 against opposite sides of which are bolted beams 35 which constitute a sweep and the outer ends of these beams are secured together by one or more cross members 36 and the terminal portions are adapted to have connected there with any suitable clevis, not shown, whereby the driving head 34 may be rotated. Mount ed within the driving head is a lever 37 having a cam head 38 connected with theupper end of the short shaft 33 carrying the clutch member 32 and it will be seen that when this lever 37 is properly swung the shaft 33 and member 32 will be elevated to disengage the clutch members 31 from the clutch members 30 and break the driving connection between the head 34 and the gear 29.

Mounted upon the forward end of the base 10 is a horizontal roller 39 adjacent which are mounted spaced vertical rollers 40 and all these rollers cooperate to form guides for the cable 41. This cable is wound about the drum 21 and also about the drum 22 engaging within the grooves 24. At its free end the cable 41 carries a head 42 with which are connected trip links 43 and any suitable cable is carried by these trip links and is adapted to be placed about the stump to be pulled.

In order to provide means for manually taking up slack in the cable on the drum 22, I provide a lever 45 which carries a head 46 engageable within the trunnion at the top of the drum 22 and this head 46 carries teeth 47 engaging with teeth 48 carried by the upper end of the trunnion so that when the lever 45 is reciprocated the drum 22 may be rotated to take up any unusual slack in the cable 41.

In order to hold the cable properly associated withthe drums to prevent tangling and to insure proper winding into the grooves 24, I provide the bottom, and top plates 10 and 16, respectively, with lateral arms 49 and 50, between which are journaleddollies or guide rollers 51 which are located adjacent the peripheries ofthe'drunis for properly feeding the cable 41 thereonto. One of the dollies adjacent the drum 22 has its periphery formed with a groove and its spindle 52 engaged by the pointed end 53 of thethreaded shank 54 of a hand wheel 55. The groove in the dolly cooperates with one of the grooves in the adjacent drum to receive the cable,.and the adjustment of the dolly permits variation of its frictional engagement with the cable.

In order to prevent retrograde movement of the drums,I provide the bottom surface of the drum 22 with a series of recesses 56 which are adapted to engage upon a dog 57 pivoted, as at 58, and having anextension constituting a handle. This dog is engaged by a spring 60 which normally urge it into engagement with the recesses 56. V

In the operation of, the device a suitable cable connected with the links 43 and 44,.is disposed about the stump to be pulled and a team of horses or the like is then hitched to the draft beams 35 which form the sweep. When the sweep is rotated and the lever 87 is in its lowered position, it will be obvious that rotation of the head 34 will cause rotation of the gear 29 and consequent rotation of both the drums 21 and 22 in the same direction and these drums will operate to pull upon and wind up the cable 41 and consequently pull upon the cable, not shown, carried by the links 43 and 44, which will result in extracting the stump. As the cable 41 is thus wound onto the drums, it will. be seen that it will pass from the drum 22 and fall upon the ground. will be seen that any length of cable may be used as the portion wound up is always taken care of. Owing to the provision of the grooves .24 in the drums, it will be seen that the cable will be properly let onto the drums without tangling or without any other undesired complications. 7 r

lVhile I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In a stump puller including simultaneously driven grooves, and'a cablewound upon the drums, a dolly arranged adjacent one drum and having a peripheral groove mating with a groove in the latter, and crew means for shifting the dolly toward or from the associated drum. V j

2. In a stump puller including simultaneously driven spaceddrums having vertical axes, the drums being grooved, anda cable wound upon the drums; a vertically disposed dolly arranged adjacent one drum and having a peripheralgroove mating with a groove 7 in the adjacent drum, and screw meansfor shifting the dolly toward or from the associated drum. j

3. In a stump puller including simultaneously driven spaced drums formed with grooves, and a cable wound upon the drums, a dolly arranged adjacent one drum and having a peripheral groovemating with a groove in the latter, and means for shifting the dolly toward or from the associateddrum.

In testimony whereof I afilx my signature.
