PATENT ALMERON MCKENNEY, OF BERLIN, WISCONSIN.

IMPROVEMENT iN STUMP-EXTRACTORS.

Specification forming part of Letters Patent No. l 62,936, dated May 4, 1875; application filed March 25, 1875.

CASE A.

To all ywhom t may concern:

Be it known that I, ALMERON` MOKENNEY, of Berlin, in the county of Green Lake and in the State of Wisconsin, have invented certain new and useful Improvements in Stump- Extractors.; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specication.

The nature of my invention consists in the construction and arrangement of a stump and grub puller and rock-lifter, as will be hereinafter more fully set forth.

'In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in Which- Figure 1 is a rear elevation of my machine. Fig. 2 is a transverse section of the axle, showing the inner side of one of the wheels. Fig. 3 is a longitudinal section through one end of the axle, and the wheel placed thereon.

Figs. 4 to 9 are views of detached parts of my machine.

Arepresents the V-shaped lever-frame made of the best seasoned timber, to resist the breaking strain to be applied to it. This frame rests upon flanges B B of the axle C, and is provided with suitable cross-pieces extending across between the two parts of the lever, with joint bolts for support. A bent crossbar, D, of iron extends across the lever-frame at the lower end, and is strongly bolted to each side piece of the frame. This bar answers the purpose of a bite to set against the sapling when the pull is made, and it may be permanent. or movable, as may be required. It is near the ends provided with shoulders a, which sit against plates on the side pieces to keep them from pressing inward. This bar is bent downward below the edges of the side pieces to admit of the machine being placed nearer the stump or tree, and also to provide a resting -place for the stump while being moved. In some cases I may extend the bar D straight across instead of bending it. In the middle itis provided with a sharp edge, b, to set against the tree. 1n immediate conjoint.

nection with this lever-frame is the axle C, provided with bottom and side flanges B placed a trifle inclined near the shoulders, forming straight gains across the axle for the two parts of the lever to rest in, and to which they are securely bolted. The axle Gis made hollow to secure lightness and strength, and also to admit of an iron bolt or rod, d, passing through it to keep the wheels up to their proper shoulders. The nuts j' on the ends ot' the rod d screw up against caps or large washers h, which set against the ends of the axle. These caps have short tubes e, which extend parallel to the bore and into the hollow axle, the'rod d passing through said tubes to hold all in place. The cap h also sits under a light edge or flange, of the hub of the wheel, which flange forms a sand band to cover thc A similar projection, i is formed upon the hub on the opposite side of the wheel to coverthe joint at the shoulder of the axle, and these projections serve to keep the sand from the journals, which, being thus protected, may be run without lubricating. The washer lor cap h is provided with one or more small V-shaped tongues or projections, z, on the inside face, which fits into similarly-shaped notches in the end of the axle, to keep the cap and nut from turning by the revolution of the wheel.

By these simple means it may be seen that the bearings of the wheels may be run very close, and yet turn freely; and by revolving true it enables the brace-hooks to be kept iu their proper places for locking the wheels, which is a very essential pa-rt of the operation.

Another important part in connection with the axle is an iron rod, lc, which runs through the flanges B B and lever'- frame A, and through lugs m m on the axle. This rod is used for the clevis E or other hook to hook onto 5 and it serves also to distribute the strain along the entire length of the axle between the shoulders. lever-bearings, being placed near the shoulders enables a long axle to be made without the danger ot' breaking, which experience has proven to be a serious difficulty with machines heretofore made on a similar plan, where the lever is placed in the middle of the axle, and

FFC?.

This, together with the the draft of the clevis or other hook being also from the middle of the axle. An axle of sufficient length is a very important consideration, on account of straddling the stump or rock, and also keeping the machine right-side up, and balancing the stump in the middle in a low position, instead of poising it on the top of a single lever, the wheels in such case being too near together` to form a base suihcient for a top-heavy load.

The wheels of my machine are each formed of two pieces of plank, G G, crossed in the middle at right angles, and halved together,A

through the center of which a metallic tube, p, passes, said tube having a circumferential liange, a, cast on one end, the diameter of the llange being about the same as the square of the crossing of the planks G, where they are halved together. Another flange, S, of the same dimensions is fitted snugly on the other end ofthe tube p. The two parallel faces of these flanges lie llat against the planks G G, and are strongly bolted through the same. The tube and anges form the joint-protecting lian ges my, above described. The wooden parts of the wheel are then completed by illing in between these extended arms a sufficient length to make the width of the fellies, and then any desired thickness of plank is added to each side of these to form the breadth of tread of wheels. Cog-wheels H are then bolted to the inner sides ofthe wheels.

These wheels may be used either with or without tire, the spaces between the extended arms affording sufficient room to bolt them on transversely through the fellies. The crotchlever A is strongly ironed at -the top, where the two parts are united. An iron plate, I, is set into the timbers between the two parts, and a stirrup, t, of band-iron, is passed over the top and down the sides of the lever, and all strongly bolted together. The middle plate 1 is vformed with a strong tenon-bolt, c, at its upper edge, which extends upward through the band-iron and is screwed fast by a nut. 1t has also suitable ears projecting outward beyond the wood of thelever, through the front one of which is passed a long link, K, for the team to draw from, and in the rear one is a heavy gripe-link, J, for the support of the slotted extension-bar L. An iron plate, w, is bolted on the rear side of the lever at the top for the support of the under side of the extension-bar, and to keep the gripe-link in a proper position when the extension-bar is pushed upward through it for adjustment to the length required. The upper end ofthe extension bar L is made broad and thick enough to lill the inside of the link J, and the under side is flat to sit down upon the irons of the lever, the outside being rounded to iit the link and provided with notches into which the link will drop, griping the bar tightly and holding it fast when the draft is applied to it. This bar extends downward to near the ground, where it is widened and formed with slots af, to admit hooks connecting it with the grappling-hooks. AThe frame or lever A has on each sidea pivoted brace-hook, M, the lower or hooked ends of which are to drop into the cogwheels H, on the inner sides of the wheels G, to lock said wheels rmly when the machine is once set foroperation. The hooks are raised from the cog-wheels H by means of a rod, b', passed through the frame and flattened or notched on one side, near each end, and at one end provided with a crank or handle. Vhen this rod is turned so that the notches arc against the upper ends of the brace-hooks M, their lower ends can fall into the cog-wheels, and lock the driving-wheels when the pull is to be made. To unlock the brace-hooks the rod b is turned so as to bring the rounded portion thereof against the brace-hooks, thereby lifting their lower ends out of the cogwheels. The lever-frame A is on each side provided with a suitable handle, d, for handling the machine, and has also strips e of band iron on the upper edges at the lower end, which strips are fastened by the same bolts that fasten the lever A to the ilanges B B. These strips protect the wooden frame and provide a bearing for an iron platform for raising and carrying rock or stone. This platform is constructed of two or more cross-bars, N, of iron, which extend across near the lower ends of the levers, and are bent downward between the same, to form a concave bed, and at the ends of said cross-bars are formed hooks c', with-shoulders on both sides of the two parts of the lever. 0n the cross-bars N are fastened two or more longitudinal iron bars, O O, two of which are formed of one piece bent to form a projecting curved edge at the lower end of the machine. This platform is fastened to the lever after removing the cross-bar D, and is applied to the rock or stone by elevating the lever of the machine a little past a perpendicular position and allowingthe curved edge of the platform to sit down against the side of the rock, in a similar manner to a warehouse truck in raising a box or other article.

When the machine is so placed to the rock to be raised, and the rock having been nicked at suitable points for the grappling-hooks l to hold, the rope and hook may be so adjusted as to give the rock something of a rolling lift when the power is applied, and when it has been raised a short distance it maybe propped up, the lever pushed back, and the extensionbar raised to take up the slack, and the team may then move forward, bringing the lever down to a horizontal position, and thus raising the rock onto the concave bed. It may then be adjusted by a bar to its proper balance for moving to any desired distances.

The clevis E, above mentioned, is formed of one metal bar bent round in the center, and having two parallel arms with hooks m formed on their ends, to be hooked onto the clevlsrod k.

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

1. In a stump and grub puller, the combination of the crotched lever A and the aXle (l, having flanges B B formed thereon, all arranged substantially as and for the purposes herein set forth.
