STUMP-PULLER.

SPECIFICATION forming part of Letters Patent No. 548,278, dated October 22, 1895.

Application and July 2,1395. serai No. 554,698. (No model.)

To all whom it may concern:

Be it known'that I, WILLIAM M. TODD, a citizen ot' the United States, residing at Lafayette, in the county of Tippecanoe and State of Indiana, have invented certain new and useful Improvements in Stump-Fullers, of which the following is a specication.

My said invention relates to that class of stump-pullers having vertical winding-drums and generally operated by horsepower; and it consists in certain improvements in details of construction and arrangements-of parts of such machines, as will be hereinafter more particularly described and claimed.

Referring to the accompanying drawings,l which are made a part hereof, and on which similar letters and numerals of reference indi# cate similar parts, Figure l is a perspective view illustrating myimproved stump-puller as it appears in use; Fig. 2, a vertical sectional view, with the winding-drum in elevation, as seen when looking in the direction indicated by the arrows from the dotted line 2 2 in Fig. 3 Fig. 3, a horizontal sectional view on the dotted line 3 3 in Fig. 2 Fig. 4.-, a side elevation with the winding-head at right angles with the position shown in the other yfigures and unshipped or raised out of engagement with the winding-drum; and Fig. 5 a detail View of the lower end of the unshipping-lever.

In said drawings the portions marked A represent the base of the framework of my improved stump-puller; B, the upper portion of said framework; C, the winding-drum; D, the winding-head; E, the operating lever "or sweep; F, the operating rope'or chain; G, the stay rope or chain; H, the pawl or detent; I,

a lever for operating said pawl or detent, andv J the unshipping device or lever.

The frame, composed of the membersA and B, is preferably so formed that said members come together at one end, where they are directly united by the bolt 1, and at the.k other end they are connected by the standards 2. Upon the upper side of the frame part Bis a circular track b, upon which the windinghead D rests and revolves when the machine is in operation. Bearings are formed in these parts A and B to receive the ends or gudgeons of the winding-drum C. The structure as a whole is preferably mounted on timbers or runners B, upon which it may be conveniently transported from place to place.

The winding-drum C is mounted vertically in bearings in the frame A B and has the operating-rope F attached thereto, which rope is wound thereon in the operation of the machine. At its lower end just above the bearing or gudgeon it is provided with ratchetteeth, as shown most plainly in Fig. 3, with which the pawl or detent H is adapted to engage, said ratchet-teeth being formed with their faces in line with the axis of said winding-drum. At the upper end larger and different ratchet-teeth c are formed, and with these corresponding ratchet-teeth on the lower side of the Winding-head Dwill normally engage. ing stern c', extending into a perforation in the winding-head, as shown most plainly in Fig. 2, which stern serves as an axle around which said winding-head will revolve.

The winding-head D is loosely mounted on the track b on the frame and is adapted to revolve thereon. Its lower surface has large ratchet-teeth d, adapted, when said head is in its normalposition, to engage with the corresponding large ratchet-teeth on the winding-drum C, but which are also adapted (upon occasion) to be lifted out of engagement with said winding-drum, as shown in Fig. 4.

The lever or sweep E is attached to the wind- It has also a central upwardly-project-l ing-head D and is the means by which power is applied to said winding-head, as is usual,` from the horses or other means for applying force.

The rope F is attached at one end to the winding-drum C and at the other end to the stump which is to be displaced. The operation ofthe machine in the winding of the drum winds up this rope and pulls the stump, asis illustrated and will be readily understood.. l

The rope G is a stay-rope (or chain) acting oppositely to the pull of the machine and is connected at one end to a point at or near the lower side of the machine and at the other end by means of a clevis G to a point at'or near the upper side of the machine. The means of connecting said clevis to the proper point on the machine is usually the cross pin or bolt g, which tits in a suitable notch or de- IOC) pression in the adjacent face of the frame part B, as shown :most plainlyin Fig. 2. This rope being connected at both the upper and lower portions of the machine holds it steadily and Without tipping, no matter how far up the rope F may be wound on the drum C.

The pawl or detent H is mounted -in a horizontal bearing in the lower frame part A and is provided with a preferably square end which projects into the path of the ratchet formed on the lower end of the windingdrum C and is adapted to engage with theteeth of said ratchet. A spring h normally holds this pawl or detent forward into suchen gagement.

A lever I, suitably pivoted, is connected to the rear end of the pawl or detent II and is adapted to force the same back out of engagement when desired. Theweight of ,this lever and the strength of this spring -h are so proportioned relatively to each other `that when the lever `is thrown in one directionras shown bythe dotted lines in Fig. 2, the spring being free to operate is suiicient to hold said pawl or detent into engagement `with the,

ratchet; but when said leveris thrownlin the other direction, as shown inFig. 4, its weight is suflcient to compress the spring and `hold the pawl or detent outot engagement with the ratchet. Thus, when it isdesired to unwind the rope, all that is necessary is to `throw this lever I into that position where its weight will operate to compress the spring, when the winding-drum will be relieved and held -relieved from the operation of the detent.

The unshipping-lever J `is adapted `to rest over the track b, and its `engaging end is forked to pass astride the central and downwardly-proj ectin g portion of the winding-head D, as shown most plainly in Fig. lLandis thus suited to the work of raisin g-the winding-head out of engagement with the drum. When the pawl or detent -I-I and winding-head D are both thrown outof engagement with the windingdrum, obviously said winding-drum is entirely free to be run back, as desired. While this unshipping-lever may be made all in one piece, if desired, I prefer to have its handle J in a separate piece, and the head J being of iron, with a suitable socket for lsaid handle, said handle may thus be a common wooden handspike, adapted to be inserted or removed at pleasure, while the head .I will commonly remain in place, ready to be used upon any occasion, as desired.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, ina stump puller, of the frame-work, a winding drum vertically mounted in bearings in said frame-work and provided with a'ratchet at the lower end, a pawl or detent II mounted in horizontal bearings in said frame-work and adapted to engage with said ratchet, a springlh adapted to hold said pawl or detent normally into said engagement, and a lever I by which said pawl or detent may be thrown out of engagement, saidlever'beingpivoted as described, and havingthat proportion'of weight that will enable it to overcome the spring and hold said detent out of engagement when desired, substantially as shown and described.

2. The combination, in a stump puller, of the frame-work constructed as described, a vertical winding-drum mounted in bearings in said frame-work and provided with a retaining ratchet at the lower end and large vertically faced ratchet teeth at the upper end with a central Aspindle extending -up inside of and to a point considerably above said ratchet teeth, a pawl I-I,fa `spring h adapted to `automatically force said pawl into engagement with the retaining ratchet at the lower end, a lever Iadapted to shift and hold said ratchet outof engagement, a w-inding head at theupper end having a central socket adapted to tit overthe spindle of the winding drum and `provided with large vertically-faced ratchet teethadapted to engage with the corresponding ratchet teeth at the upper endof said winding drum and alsofitted to `receive the operating lever yorsweep, a circular track on the upper surfaceof the frame-work, and corresponding track portions -on the under side of the winding head,said several parts being constructed, arranged and operating substantially as shown and described.

3. The combination, ina stump puller, ot the frame-work composed `of the base A and the upper portion B connected by the bolts and standards l and 2 and mounted on the 4runners R, the vertical winding drum C havon a stem extending up from the winding drum and engaging with the driving ratchet thereof,thefdriving lever or sweep E, the operating rope or chain F, thestay rope or chain G connected to a stay post or stump at a central point and to theframe part A at one end and to a clevis G attached to the frame part B `at the `other end, the automatically operating pawl H, the lever I for operating said pawl, and the bifurcated lever J `for unshipping or disconnecting the driving head from the winding block, all substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Lafayette, Indiana, this 26th day of llune, A. D. 1895.

WILLIAM M. TODD.
