STU M P-EXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 452,215, dated May 12, 1891.

Application filed September 9,1890. Serial No. 364,486. (No model.)

To aZZ whom it may concern;

Be it known that I, J OHN CORNELIUS, a citizen of the United States, residing at Oakland, in the county of Garrett and State of Maryland, have invented a new and useful Improvement in Stump-Extractors, of which the following is a specification.

My invention is an improvementin stumppullers intended for extraheavy work, as in the pulling of very large stu'mps;'and the invention has for objects, among others, to provide a construction of framing in which the frame will in no wise interfere with the ready manipulation of the chain and cable; to provide improvements in the mechanism for supporting the drive-worm, looking to the convenient shifting of such worm into and out of mesh with its worm-wheel; to provide a simple construction for the connection of the anchor-bail, and to provide other improvements, as will be hereinafter described.

The invention consists in certain features of construction and novel combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a top plan view of my machine as in use, the worm being thrown out of gear in dotted lines. Fig. 2 is a side View thereof. Fig. 3 is a vertical crosssection of the machine, on about line 3 3 of Fig. 1, through the axis of the main wheel. Fig. 4 is arear elevation of the machine. Fig. 5 is a detail cross-section, on about line 5 5 of Fig. 4, of the rear shoe and its re-enforce plate; and Fig. 6 shows the manner of supporting the worm and of adjusting such worm into and out of mesh.

. The main frame is provided with side plates or frames A, made, preferably, of cast-steel annealed, and formed with feet a, which are bolted upon the shoes'B B, and have at their -front and rear edges flanges which lap along the respective edges of the shoes and brace the side frames firmly to the shoes. The side frames Aare of a special construction and form an important feature of my invention. At their rear ends they are provided with upwardly-proj ected forwardly-facing hooks C, which are formed integral with the side plates A, and form a convenient means of attachment for the anchor-bail D, as shown. By this construction the anchor-bail can be readily applied to and removed from the side frames A, and when engaged therewith will be held to the side frames in a strong rigid manner.

The upper edges of the side frames curve for incline gradually downward from the rear to the front end of the machine, and at a point slightly in advance of the center of the said plates I form bearings E for the main wheel.

These bearings are arranged near to the upper edge of the frames A, and at a point just in rear of the point of greatest slope or inclination. By preference I provide the bearings by forming sockets in the inner faces of the side frames, such sockets being fitted to receive the ends of the shaft portions of the chain-wheel, as presently described, and

oil-holes 6 being formed to lead inward to the bearings E from the outersides of the frames A, to enable the convenient lubrication of the said bearings E, as will be readily understood. The plates A are perforated at e concentrically of the sockets or bearingsE for the passage of the brace-rod.

At their rear ends the side frames A are connected by the top cross-bar F, formed at its ends with flanges f, which lap alongside the outer edges of the frames A, the bar F being bolted to the top web or flange of the frame A, as shown. At each side of the machine I provide a strut-brace G, having a foot-piece bolted through the rear shoe B, and a top piece lapped under the top web or flange of the frame A and bolted through such web and through the crossbar F, as shown.

The main wheel 11 is composed of the wormwheel made in the two side sections I I, the chain-wheel J between the said sections, and the drums K, arranged outside the wormwheel sections.

. In the construction shown the worm-wheel sections I are formed integral with the chain'- wheel J, and are provided with outwardlyextended axles or trunnion-like portions "1 which journal at their outer ends in the bearings E, the wheel being held in the said bearings, and the side frames A being braced firmly together by the brace rod or bolt L,

TOO

which is passed through the wheel and side frames and secured outside the said side frames, as shown most clearly in Fig. 1-3.

The drums K are formed with hub sleeves or portions 7;, which lit on the axle or trunnion portions i of the worm-wheel and are secured by pins or in other suitable man ner. The rims 1i of the drums are supported by spokes K from the hubsleeves 7t, and are preferably grooved spirally, as shown, from end to end.

It will be noticed that the relation of the drums K to the side frames is such that the upper and front faces or portions of the drums at M project above and forward clear of the frames A, such relation being aided by the downward curvature or inclination of the upper edge of the frames A toward the forward ends thereof, as shown. Such constrnction leaves the top and front sides of the drums entirely exposed or unobstructed, so that the wire cables may be readily adjusted on said drums and can be led off therefrom to the side in adjusting the machine for use without such cables coming in contact with the side frames, as will be seen from the drawings.

The ehain-whcelJ is of equal diameter with the drums K, so that the turning of the main wheel will wind the chain N on the chainwheel and the cable 0 on the drum K equally, enabling the lengths of cable and the chain to coact in drawing a stump.

The chain N is guided to its wheel J by the pulleys P in frame 1), which frame sup ports the chaiirdischarge chute Q, which has the tongue or stripper (not shown) for clearing the chain from its wheel. This dischargechute leads off laterally and terminates at a point outside the line of the wire cable, so that the discharged chain will not fall upon the wire cable as the operation of pulling proceeds. ItwillbenoticcdthatthecableO,which is a strong wire rope,isin the form of abridle, being wound at its opposite ends upon the opposite drums and secured at its ends to the drums by fitting its ends in openings in the drums and securin g them by means of wedges O driven into such openings and clamping the wire therein. In gearing the machine for use this wire cable is looped at its center through a ringr on one end of a cable R, such cable R being passed through a single sheave S, and thence off to a stump, around which it is passed and secured. The chain N has at its free end a hook it looped in the ring 1', so thatthe chain and wire cable pull together. A chain or cable T leads from the sheave S off to the stump to be pulled, and the operation of pulling proceeds by properly turning the main wheel. It will be noticed that the cable ends are secured near the outer ends of the drums and move toward the worm-wheel sections as the cable winds on the drums, such movement of the cable being its natural one, as the stress of pulling tends to draw the cable-lengths inward toward each other, and

it is advantageous in the use of the machine, inasmuch as when the cable winds on the 111- ner ends of the drums and is subject to the greatest strain its lengths are brought close to the worm-wheel sections, thus bringing the resistance and the power into close relation, as desired. The worm U,which is formed to mesh the worm-wheel sections, is supported in a frame which is formed with upperandlower plates \V and a vertical or connecting bar A, extended between and connecting the plates \V. The worm journals in the plates \V and tits between the same, its shaft it extending above the upper plate W and up through a slot in the rear cross-bar, which connects the side frames A. At one end the plates V have openings to for the pintlc or hinge rod Y, while at their opposite ends they have open: ings in for the locking-rod Y, which rods St Y pass down through openings in the rear crossbar, thence through their respective openings in the plates \V, and pro ect at thei r lower ends into sockets in a brace-plate B fitted and bolted on the rear shoe and hav ng at its front and rear edges flanges 13', which lap down alongside the rear shoe and are strongly braced in place thereby.

The locking-rod Y,when rem oved to unlock the worm-frame, may be inserted in a socket X in bar X and serve as a lever for throwing the worm-frame outor in to adjust the worm into or out of mesh with the worm-wheel sections.

Now it will be understood that in my machine I secure acombined chain and wire-cable pulling action, and it is my purpose to use both the chain and the wire cable for extra heavy work, such as the pulling of unusuallylarge stumps, and the cable and chanrmay both be used in ordinary work; but it will be seen that in ordinary work the chain may be removed and the wire cable alone be used. Vhen the wire cable and chain have been drawn fully up to or into the machine, the worm may be thrown out of gear and the cable and chain be quickly pulled out to position for use.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The improved stump-puller herein described, comprising the main wheel having the chain-wheel, the worm-wheel sections arranged on opposite sides of such chain-wheel, and the drums arranged alongside the wormwhecl sections and adapted to receive a wire cable, the worm, and the necessary framing, all substantially as and for the purposes set forth.
