T0 ALL .WHOM IT MAYCONCERN:
Be it known that I, TRUMAN S. ANGEL, of Watertown, in theA county of Jefferson, and State of New York, have invented an Improvement inv the Construction of a Stake and Pole-Sharpener.; Aand I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon. i
The nature of my invention consists inthe construction of said sharpener, and which is so constructed that it can beiused vas a hand-implement, or it can be propelled by horse, steam, or water-power.
To enable ,others skilled in the art tovmake and use my said invention, I will proceed to describe its construction and operation. i Y I My Sharpener resembles, in its generalform, the well-known pencil-sharpener, and my invention relates to improvements on that implement, I hereby disclaiming any claim of invention in the construction of said pencil-sharpen er.
Figurel is a longitudinal section of my Sharpener, and
Figure 2 a persectivc view, showing the Sharpener mounted upon an appropriate frame,`with driving-pulley,
beltkand balance-wheel.
The Sharpener is a hollow frustxiin of a cone, terminating at its smaller end in a solid cylinder, which cyl- 'inder has a diameter equal to that of the smaller end of the frustum, and a length about yone-fourth ofthe frustum. c e is a knife, set diagonally to the longitudinal axis of the Sharpener, and is afliired to the rib c by the screws e e e.A rlhe knife passes through a slot, fcut through-the side of the sharpener to the interior, B B, of theharpener, the knife having a suiiicient width to reach the stake or pole to he sharpened. The knife has, where. thc-.screws 'pass through it, a corresponding number of slots, in the right direction and ofthe proper length to permit the said knife to be adjusted inwardlyand outwardly the required distance. The knife is also set in such amanner. that it will give a drawing or shaving cut'with the grain of thestakes and poles, and the'slot through which it passes is at the proper diagonal to the longitudinal axis of the Sharpener. The knife can be removed for the purpose of sharpening and repairing. As the stakes and poles have diii'erent diameters, varying, say, from two.to four inches, and as itiis required that they be sharpened for a length of about fourteen inches, it is obvious that the inclination oi' the knife must be varied `for these dili'crent diameters, so that the stakes and 4poles may be sharpened for the length mentioned. l To meet this requirement, either end of the knife will be adjusted further in or ont than itis shown in g. 1. This will of course make a change in the 'bevel in the cut, the smallest poles having the ilatt'estbevel, and the largest the reverse. The stakes and poles will be sorted as vto sizes,1and when the knife is adjusted for particular size, all of that `size will be sharpened, then the adjustment will be changed for another size, andsoon, through all the sizes.
' lo-prevent the sticking and jamming which would arisefrom the friction between the inner side of the sharpener and the stakes and poles, the Sharpener is providedwith' three conical friction-rollers, equidistant from each other, one of which, D D, is shown in both iigures. These rollers are set in slots cnt in the sides 4of' the Sharpener, in the line of its longitudinal axis, which slotsext-end entirely through such side. The 'rollers are .provided with journals at each end, on which ,they revolve, one of which journals has its bearing in the side of the' s harpener, andl the other also, b ut the lhtter is held in vposition by the cap a. The 'rollers are set n such a manner that their inner surface projectshbeyond the'inner surface'of the Sharpener, and so that these surfaces are parallel to each other.. A conical form is given to the rollers, and they are fset with their larger ends. towards the larger endof the Sharpener, in orden to secure a vuniformity of sp'eedjio the surfaces of the rollers and the inner surface of the sharpener. IfA the rollers were cylindrical, it is plain that the difference iii-speed between 4the rollers and sharpener would cause great friction, and a consequent jamming in the operationof sharpening'stakes and poles. 1
When the 'Sharpener is used as a hand-implement, it will be mounted on the frame, A, and a crank attached to the arbor E. When propelledfby power, the drivingpulley G and the balance-wheel V'I will be attached to said arbor, andthe power transmitted by the belt H, the straps F F holding the sharpener in its bearings. When operated in either way, the stakes and 'poles are grappled to asliding frame, m'oving on a table so constrncted that the ends of the stakes and poles will enter the Sharpener at B B, and when sharpened, said stakes andpoles will be withdrawn by reversing the movement of the sliding frame.
What I claim as my invention, and desire to secure by Letters Patent, is
A tool for sharpening sticks, stakes, and poles, consistilng'of a hollow frustum of a cone, having inserted longitudinally in its shell conical rollers, and an adjustible oblique-cutting knife,- all constructed and arranged to operate substantially as described. v f
