UNITED STATES PATENT OFFICE-.7-
ZBURTON JAMES ROBINSON, OF STANLEY, WISCONSIN.
STUMP-PULLER.
T 0 all whom it may concern Be it known that I, BURTON J. RoBINsoN, a citizen of the United States, residing at Stanley, in the county of Chippewa and State of \Visconsin, have invented a new and useful Improvement in Stump-Pullers, of which the following is a specification.
' My invention is intended to offer a simple construction that can be readily set up in the field, is designed to be easily taken apart when change of position is required, light, as to weight, and free from the mechanical assemblies that complicate similar contrivances now extant.
The structural features that compose my device, are such as may be readily obtained in any district wherework of the kind, herein referred to, is being performed. While the drawings show a finished and well formed construction, it will be easily observed that this arrangement could be erected just as efiiciently from timber material which is present in plentiful quantities about the field of operations. The metallic parts that are embodied in the structure set forth, are, practically, indestructible and may be employed for any sort of makeshifts that will answer the purpose. The design is a studied effort at simplification in providing an improvement that has a minimum of structural members, most of which can be discarded when the undertaking, at hand, is completed, or, when shifts to the next territory to be worked is located at an unusual distance. I
Noticeably absent from the arrangement to be described more fully in the following text, is the freedom from chains, cables and winding means, et cetera, that are frequently employed in stump-pulling contrivances; an elimination that works for the rapidity of application, positiveness of action and adaptability for being operated understandingly, by the class of workers that follow this line of endeavor for a livelihood and who cannot be expected to, intelligently, manipulate mechanical assemblies successfully.
The economy displayed in providing a means for the performance of this class of work, is a feature that cannot be underestimated, because of the hardship involved by having to delay operations for long periods of time while waiting for repair-parts to come from distant centers and necessitating the employment of skilled help to in- Specification of Letters Patent. Pat t d J l 27 1920 Application filed December 27, 1919. Serial No. 347,806; i T V composed of material always nearby is a great asset in favor of my device, especially,
as it refers to work, generally, performed 7 in localities where there is, frequently, a
dearth of those conveniences that obtain in more populous centers.
I attain the objects and advantagesherein set forth by a construction, fully, illustrated in the accompanying drawings and described in the annexed specification, the particular-features being pointed out in the claim following the specification aforesaid, all of which form parts of this application, in which:
Figure l is a perspective view showing a construction that embodies my invention.
Fig. 2 is an enlarged fragmentary view of the top castings shown partly in section.
Fig. 3 is a detailed view of the parts at the pivotal point of the handle.
Similar characters of reference apply to like partsthroughoutthe several figures or vlews.
A triangular base A, formed of suitable timbers that will function as skids are bound together at the forward end by the plate a which is forged to offer a clevislike loop a to receive a drag-line; the opposite ends of the skids A have the clevisloops at for a like purpose, both ends, in this way, being provided with means whereby the whole structure can be shifted readily.
Erected upon the base A is the pyramidal framework B, formed of three legs that are held in place by the top or crown casting C, which has the flange 0 the said flange having a contour fashioned to provide the recesses 0 into which are fitted the upper ends of the legs that form the framework B. Further stability is given the frame aforesaid by the introduction of the straps Z2 which are bolted to the legs and to the flange c of the casting C.
Machined to nest in the casting C is a split spherically formed member D, that is centrally bored to admit a tubular shaped cylinder F, through which passes the rod E having the annularly formed ratchet teeth disclosed in all the views. The cylinder F has the flanges f and f formed at the upper and lower ends respectively of the said cylinder F, f forms the enlargement under which the member D is bolted around the cylinder F, and j forms a similar enlargement over which a casting G is fastened in like manner,
forked elements the latter being designed to embrace the sides of a box J to which the said forks are pivoted by meansv of the pins V V The box J has cast integrally with it the sockets for the reception of the operating handles IL-l 'Mounted in the box J are the pawls P-P, which are, normally, in engagement with the rod E by'virtue of the springs M--M forcing the said pawls into engagement with the ratchet formations upon rod aforesaid. V
A hook e -is pivoted at the lower end of the rod E and handholds e are located immediately above the hook member 6 In applying my invention to the removal of tree-stumps or like obstructions, I proceed, somewhat, differently from the usual custom and by the method that I follow, avoid the necessity of requiring a high power unit in that my device removes the object by pulling the roots individually and,where the roots are large and far apart, separately;
the process being as follows:
Sufiicient excavation about a root R of a stump S is made in order to admit the hook e to engage the said root, the rod E is then elevated asfar as it will go by pulling on the handholds 0 this being done the opertors work the handles H as in pumping, giving a, vertically, walking motion to the pawls 1 which oscillate about the pivot of the forks 9 the latter combination being a construction that will be understood to obtain on either side of'the box J,leaving a space between for the, free passage of the rod E. This action of thepawls, engaging the ratchet formations, tends to raise the rod E and the grapple e until the root R:
is rent assunder. This process is repeated for every root branch'that is to be broken inorder to free the stump. The clevis links on the ends of the skids or runners A permit of hitching so that device 'may be shifted by any-suitable means adapted to perform same.
Having described my invention, what I wish to claim and protect by Letters Patent, 1s:
' Astump pulling structure having a pyramidal frame upon slidable skids, said frame provided at its apex with a spherical bearing :that sustains a pendant sleeve member adapted to offer a bifurcated pivotal con- .nection' embracing a rocking arm, the latter being apertured to allow passage of a vertically disposed ratchet bar at a point beneath the spherical bearing aforesa d.
