VALDEMAR HUGO SPANIER, OF DEVILS LAKE, NORTH DAKOTA, ASSIGNOR OF ONE-HALF TO JOHN W. MAHER, SAME PLACE.

GRUBBING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 614,510, dated Novemte'r 22, 189e. Application filed `January 12, 1898. Serial No. 666,410. (No model.)

To all rch/0m t may concern:

' Be it known that I, WALDEMAR HUGO SPA- NIER, a citizen of Sweden, residingV at Devils Lake, in the county of Ramsey and State of North Dakota, have invented certain new and useful Improvements in Grubbing-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference" marked thereon, which form a part of this specification.

My invention relates to grubbing-machines of that class that are usually employed in pulling up stumps, grubs, small trees, duc.; and the objects of my invention are to provide an improved apparatus of the class described which will be simple in construction, easy to operate, and comparatively cheap of manufacture.

With these objects in view my invention consists in the construction and combination of parts shown in the accompanying drawings and described in the following specification.

In the drawings, Figure 1 is a perspective view showing the machine in operation and the manner of applying it. Fig. 2 is a top plan View of the machine complete with lever applied. Fig. 3 is a longitudinal sectional view taken on the line as a: of Fig. 2. Fig. 4 is a plan view of the lever which forms a part of the machine, a portion of the'handle being broken away. Fig. 5 is a transverse sectional view taken on the line y y of Fig. 2.

Referring to the drawings, 4 and 5 are two oblong plates of similar form, having placed between their ends cross plates or bars 6,

. thereby forming the frame of the machine.

. slot 9, and upon each side of said slot are arranged a series of short longitudinal slots 10 and 10', said slots 10 being formed between the angle-strips 11, which are secured upon the upper face of said plate 4, on either side of said slot 9, and between which the L- shaped levers 12, which depend through the slots 10, are pivoted. The bottom plate 5 is also provided with a central longitudinal slot 6o 9 and has a series of slots 13 upon either side thereof immediately below the slots 10 in the plate 4. The pivoted levers 12, which depend through the slots 10 and corresponding slots 13, are pivoted between the angle-strips 11, immediately above the slots 10'. in the plate `4, and are provided with depending lugs 3,

which extend downwardly through said slots 10 into the open space 16 between said plates 4 and 5. By referring to Fig. 3 it will be 7o seen that the lever 14, passing through said opening 16 and engaging the depending lug 3, will cause the pivoted levers 12 to lift, as indicated by the dotted lines in said gure, thereby lifting the depending end of the lever 12 out of the slot 13 and clearing the opening 16 both of the pivoted lever 12 and the lug 3, thereby permitting said lever 14 to pass said pivoted levers, and while it is possible to raise said pivoted levers by pressing 8o against said lugs it will be seen that any pressure directed against the front of the lever 12 will only press it more rmly against the edges of the plates 4 and 5, which form the Walls of the slots 10 and 13. 85

It will be understood that an equal number of slots 10 and 10 are employed upon either side of the top plate 4, but are placed so as to alternate with each other. In connection with said frame l employ a lever 14, consisting of 9o a iiat bar of metal, (steel being preferably used,)and near one end,at the edge,are formed two small shoulders 15. The opposite end of the lever is provided with a handle 2, preferably of wood, which may be of any desired length and into which the bar 14, which constitutes the lever, is inserted, said handle being provided with metal bands or ferrules 17, the object of which is to prevent the splitting of the handle. Astrong chain 18 is secured 10o toa ring 19,which passes through the opening 8 in the end of the frame, and to the opposite end of which is secured a hook 20. This hook 2O is adapted to be secured to an anchor-chain 21,which is passed around a firm object, such as a tree or stump. A chain 22, havinga large ring 23 at one end, is adapted to be passed around the stump, grub, or stone which is to removed. The ring 23 is passed into the central slot 9 in the plates 4 and 5 and the lever 14 inserted through said ring in the opening 16 between the plates 4 and 5, with the ring resting between the shoulders or projections l5 on said lever, as illustrated in Fig. 2.

In operation the lever or bar 14 is passed through the opening 16 between the plates 4 and 5 and through the ring 23 at the righthand end of the apparatus, as shown in Fig. 2, or at the point indicated by the arrow a, with the back of said lever resting against the bar 6 at 24. In using the plate or bar 6 as a fulcrum the handle end of the lever is moved backward until the opposite end engages theiirst lug 3, thereby raising the pivoted lever 12 and permitting said lever 14 to pass, when said lever 12 drops into its normal position and in turn serves as a fulcrum,while the handle end of the lever is moved forward until the pivoted lever on the opposite side has been raised and again drops into place, when it in turn serves as a fulcrum until the outer end passes the next pivoted lever on the opposite side. It will thus be seen that the lever 14 graduallyT moves step by step in the direction indicated by the arrow l) until it traverses the entire length of the frame, and by so doing shortens the distance between the fixed point to which the anchor-chain 2l is attached and the stump or grub, thereby drawing said stump or grub from the ground.

It will be understood that the frame of the apparatus, composed of the plates 4 and 5 and their connected parts, may be made of any desired length and that the bar or lever 14 may also be made of any desired length, and it will further be seen that great power may be exerted by means of said bar or lever sufiicient to pullout any ordin ary stump or grub. In the drawings I have illustrated but three of the pivoted levers 12 on either side of the central slot 9, this being done for the purpose of more clearly illustrating the operation of the lever and bar; but in practice any desired number of said pivoted levers may be employed and the length of the plates 4 and 5 regulated accordingly.

It will be apparent that modifications and changes in the construction of my improved grubber can be made without departing from the spirit of my invention or sacrificing any of its advantages, and I reserve the right to make such modifications therein as rightfully come within the scope of my invention.

I-Iaving thus described my invention, what I claim, and desire to secure by Letters Pat ent of the United States, is-
