1o (LM wia/om it may concern,.- Y

Be it known that l, WILLIAM A. Mnsnn'rr, a citizen of the United States, residing at Brainerd, in the county of Crow Wing, State of Minnesota, have invented certain new and `eseful Improvements in Stein -Pullers; and I do hereby 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.

This invention relates to stump-pullers.A

One obj ect of the invention is to provide an exceedingly simple, inexpensive, durable, and eilicent device of the character stated.

Another object of the invention resides in the provision of a stump-puller embodying such characteristics that stumps may be readily u set from the ground.

With these and other objects in viewl the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the seo e of the claims without departing from t e s irit or sacricing any of the advantages of tlhe present invention.

In the drawings, Figure 1 is a side elevation of my invention. Fig. 2 is a top plan view. Fig. 3 is a transverse section. Fig. 4 is a longitudinal section.

Referring new more particularly to the accompanying drawings, the reference character 1 designates a base-plate, and the reference character 2 a top plate, one end of the top plate having its sides converging toward each other, as at 3 and 4, the base-plate 1 having perforations 5 therein, whereby it ma?? be secured firmly to the ground.

ournaled through one en of the upper and lower plates 2 and 1, res ectively are the reduced ends 6 and 7 of the rum 8, there being a vertical rotatable shaft 9, having its reduced ends 10 and 11 journaled through the said u per and lower plates, respectively, and being in spaced relation to the drum 8, the extremities of the reduced ends of the drum 8 and the shaft 9 being received by suitable bearin -boxes 12, arranged upon the .exterior faces o the plates 1 and 2.

)sighs-result of reducing the ends of the and the rotatable shaft 9 shoulders 13 and 14, respectively, are formed. Arran ed between the upper plate 2 and the'shonl ers 13 and 14 of the drurn 8 and shaft 9 is a plate 15, having its sides at one end'convergng to conform to the convergency of thesides 3 and 4 of the plate 2, there being another plate 16 dis osed between the shoulders 13 and 14 at t e lower ends of the drum and shaft and the inner face of the` base-plate 1. Fitted upon the upper reduced end 14 of the shaft 9 is a pinion 17, designed to mesh with the gear-wheel 1S, disposed upon the upper reduced end 13 of the drum 8, it being seen that the said pinion 17 and gear-wheel 18 are disposed between the plates 2 and 15, thereby holding the said plates in spaced relation with respect to eac other.

A pinion 19 is secured upon the lower reduced end 14 of the shaft 9 between the plates 1 and 15 for mesh With the gear-wheel 20, disposed u on the lower reduced end 13 of the drum Ibetween the last mentioned plates, therebysup ortin the latter ins aced relation to each ot er. it will be note that the plate 16 has the sides at one end convergin to conform to the convergency si the si es 3 and 4 of the plete 2.

Oppositely-dis osed stays 21 and'22, each having upper an lower bent ends 23 and 24, respectively, are disposed in alinement with the drum 8, the upper bent ends 23 of each stay being bent over the upper face of the plate 15 and pierced by a bolt 25, which latter is also passed thro h the up er plate 2 and the plate 15 to hol the sani, plates together and also the upper end of the stays 21 and 22 with res ect to the plates, the lower bent end 24 of the sta s 21 and 22 being disposed against the un er face of the plate 15 therebetween and the base-plate 1, there being a bolt 26 assed through the said plates 1 and 16 and t e bent ends 24 of the stays 21 and 22 for the same purpose as is the bolt 25 associeed With the upper ends of the stays. A third stay 2?' has its upper end bent, as at 28, for engagement between the converging ends of the upper plates 2 and 15, there being a bolt 29 piercing the said lates and bent end 28 ofthe stay 27. The ower end of the stay 27 is bent inwardly, as at 30, between the conver ent sides of one end of the plate 16 and theaase-plate 1 and secured therebetween b means of a suitable bolt 31. It will be o served that the stay 27 is arranged intermediate the aforesaid stays 21. and 22 IOO TIG

and in advance or rearwardly of the latter. trees will have a tendency to loosen and exA This intermediate stay is curved outwardly, as at 32, with respect to the correspondin ends of the aforesaid plates, and the sides o? the stay intermediate the said ends are bevsled or curved, as at 33, by bending outwardly upon the stay, such formation of the inner side of the intermediate stay resulting in a groove 34 upon its outer face.

The intermediate or third stay 27 is designed to receive both ends 35 and 36 of a chain or other connection 37, which is fitted over or around the tree or stump, as shown, there' being a chain or other connection 38 secured to the drum 8 and designed for connection at its opposite end with a tree or stump. Now in order to upset or extract either one or both of the stumps or trees just alluded to it is simply necessary to connect the horses or other draft (not shown) in any suitable manner to the beam 39, which is connected to the up er squared end 40 ofthe vertical shaft 9, an cause the draft to pass around the device, such movement of the draft causing rotation of the vertical shaft 9, and by reason of the pinions 17 and 19, fixedly secured thereto, cause the gear- wheels 8 and 20, with which said pinions mesh, to compel a rotation of the drum 8, it being obvious that rotation of the drum 8 will cause a tightenin of the chain or other connection 38 and pul the stump with which it is connected out of the ground. Of course the strainbetween, the puller and both stumps or tract both stumps or trees simultaneously.

1. A stump-puller comprising pairs of upper and lower plates, a drum journaled 1n said plates, a shaft journaled in said plates in spaced relation to the drum, stays connecting each pair of plates, a beam connected to one end of said shaft whereby the latter may be rotated, and means arranged between the shaft and the drum for rotating the latter upon rotation of the former.

2. A stump-puller com rising pairs of upper and lower plates, a rum Journaled for rotation through said plates, upper and-lower ear-wheels fixedly mounted upon said drum )etween the corresponding upper and lower plates, a vertical shaft journaled through said upper and lower pairs of plates, upper and lower pinions mounted upon said shaft between the correspondin pairs of plates for mesh with the aforesai gear-wheels, stays arranged between the upper and lower pairs of plates, a beam connected to one end of the said shaft whereby the latter may be rotated to cause a rotation of the drum simultaneously therewith through the instrumentality of the aforesaid pinions and gear-Wheels.

In testimony whereof I affix my signature in presence of two witnesses:
