Specification of Letters Patent. n

' Appiicaiion flied April i2, 1920. seiiai No.'373,s57.

To all whom t may concern: p Be it known that L'WALTER STOP'PLE, a citizen of the United States, and resident of Escanaba, inthe county of Delta and State of Michigan, have invented new and useful Improvements'in Stump-Fullers, of which the following isa description, reference being had tothe accompanying drawings, which are apart of this specication.

The vinvention relates to stump pullers, and more particularly to that type of puller in which adrum is rotated by a sweep.

One of the objects of this invention is to provide a simple and eflicient mounting for the drum in the frame of the machine so that the friction of the rotating drum may be reduced to take theheavy drag oii' 0f the draft animal operating the device.

A further obj ect of theinvention is to provide an eiiicientform of clutchfor the drum whereby the drum may be secured to the swee in a plurality of positions, thereby makiii'git easy to throw the machine in and out of gear.

A further object of the invention is to provide a sweepV trough for a machine of this type which willreadily accommodate sweeps of different dimensions.`

A further object of the invention is to provide effective means for holding the drum pawl out of engagement with the drum ratchet, when desired, andwhich means may be readily released by the operator to, throwL in the pawl. Y .l

VvA further object of the invention is to provide a cable connection between the frame of the machine andthe anchor stump `of such a character'V that all Ystress produced on the frame during thev winding up of the cable on V the drum` will'be transmitted in substantially a straight'line through .the anchor" vention; Fig.v 2is a plan view thereof;I Fig.

2; Fig. 4 is a section taken on the line 4--4V of'Fig.`3,-the clutch being lingFig. 5 is a detail sectional view showing the pawl-locking and releasing mechanism; Fig. 6 is a bottom view of the drum.

In the drawings the numeral 7 designates- Patented June, 1921'.

i the sweep, 8 a sweep trough, 9 the `drum I mounted in the frame 10 and provided with a ratchet llcoperating with a pawl 12, said frame being usuallyA mounted on skids 13.

The. sweep trough 8 is provided near itsV end with curved guide grooves 14 to receive v tween the trough and the plates 16 on screwing up the nuts 17 upon the U-bolts 15. rThe grooves 14 in the trough eifectually prevent any slippage of the U-bolts 15.with respect to the trough, Vand by the means thus detiibular hub portion 18 which passes down,

through the hardened steel sleeve bearing Y 75 7o 'i scribed the sweep is securely clamped to the trough. The trough is provided with a l spindle being free to rotate in a hardened y steel ring 23 having a tight pressed fit in an opening 24 ofthe lower portion of the frame means of a bolt 25, a bearing 26 and the bearing 23, the bolt 25 'passing through the bear- .f

ing 26 and bearing 23 and serving to'clamp 10. The sweep trough is held against vertin f cal movement with respect to the frame by groove 29 communicating with anopening" 30 4in the bottom of the drum and receiving y and securely holding the taper'plug end of the cable which; passes through the opening 30 of the drum Vso that the cable may be woundabout the curved periphery of theV drum'. The drum is provided at its `upperA portion with inwardly extending tooth projections 31 spaced apart to form clutch slots 32 and having beveled grooves 33 on one side thereof so as to permit of ready registration of thel clutch in any one of the series of diametrically disposed clutch slots 32.

Hub portion 18 of the sweep trough is V105 provided with vertically disposed` slots 34j and the spindle portion with verticallyl dis` posed slots 35. A clutch shaft 36 passesf through thev slots 34 and carries a clutch member 37, and eccentric disks 38 at its ends.

" Vof the machine.

These eccentric disks have grooved lugs 39 receiving the ends 40 oit' a U-shaped lever 41, which lever passes up and over the sweep and clears the same so that it may be swung to different positions without interfering with the sweep. The eccentrics 38 are adapted, when rotated, to move the clutch member 37 vertically in the slots 34, theeccentrics through the raising or" the clutch member bearing upon the flanged upper end 42 of the bearing 19. Y

The clutch member 37 consists of a flatsided block having arms 43 mounted on the shaft 36, and having clutch teeth'44 with one side beveled to coperate with the beveled notches 33 on the projections 31 of the drum and adapted to enter into the diametrically disposed slots 32 in the drum formed by the projections 31, said clutch block being guided in its downward vmovement by the slots 35 in the spindle of the sleeve and alined slots 45 in the hub oi the sweep. Y

A pawl 46 is pivotally secured to the .frame by pin 47 at the front end thereof so that said pawl is normally held in enga-gement with one tooth of the ratchet by grav* ity, the teeth of the ratchet .being beveled so as to permit the pawl to move upwardly into engagement with the next tooth when the drum is rotated in one direction by the sweep, the pawl preventing a backward rotation of the drum. When it is desired to let the drum run free the pawl is maintained in raised position" by means o a locking latch 48 which is pivotally mounted lon a Vbolt 49 at the free end of the pawl,

said latch having a projection 50 coperating with a stop 51 on the pawl, and a tooth v52 coperating with a stop 53 on the frame With this construction when the pawl is moved from .its lowered position, as shown in full lines in Fig. 5, and the latch 48 is tipped so as to swing the tooth 52 downwardly, said latch may clear the stop 53 to permit the pawl being raised to a position to clear the ratchet, such as shown by dotted lines on Fig. 5, at which time a release of the latch 48 causes the tooth 52 to engage the stop 53 and the pro- 1 jection 50 to engage the stop` 51 to form a lock for holding the pawl in raised position against the weight of the pawl. vrllhis construction provides a very simple arrange ment Jfor manipulating the pawl, as the operator can lock or unlock the pawl with one hand by a proper movement of the latch 48.

The frame 10 is preferably made in one piece of rectangular formation having

upright sides

54 and 55. Openings 56'are pron vided near the ends of the upright 55 to receive pins 57, which pins serve to connect the eyed ends 58 of cable sockets 59 secured to short cables 60, both of said cables 60 being secured at theiry other ends to the arated cables 60 this pull willV be trans-- mitted in a substantially straight line to the anchor cable 63 to thereby prevent tipping the machine while the pull cable 64 is being wound up on the drum, due to the fact that either-one or both of the cables .60 transf mits thispull to the anchor line in some instances one cable acting as a check on the other. The other upright is yprovided with a substantially centrally disposed opening'.

65 to which a power loop cable connection 66 is secured by means of a removable'pin 67 Vpassing through the eyed end of the power loop connection 66 to the aperture 65. Where one or more pulleys-V are usedin connection with the pull-rope to dislodge the stump, one of vthe cables carrying the pulley is secured to this power loop and permits the pulley to be disposed neary the` ground so that a horse may readily step over the pull-cable 'in operating the sweep, a featureV which is of advantage as lcompared with the usual construction inwhich the power pulley is carried by or directly l secured to the frame of the machine.

In the operation of this machine the 'anel cher cable 63 is connected to the anchor stump andthe cable 64 through suitable conections to the stump tovbe pulled, saidj connections including the cables and pulleys atJ or triple power is desired, and then, with the clutch 37 thrown into engagementwith the drum and the turningof the drum'in.

the proper direction by the sweep, the cable is wound up on the drum and the stump-is cached to the power loop 66 if double loosened from its anchorage in the earth.`

If at any time during the stumpI lpulling operation it is desired to let the drum-run free the clutch block 37 is raised by a shifting of the member 41 which causes the ecA centrlcs 38 engaging the bearing 19 to lift said clutch into' inoperative position, as', shown in Fig. 3. Furthermore, the drum is loosened from connection withthe pawl by:

raising of the pawl and locking of same, as previously explained. Y 'g l desire it to be understood that thisinvention is not limited to any specific form or arrangement of parts except -in ,so far as such limitations are specified in the claims.
