N. PETERS*Y PHDTO-LITHOGRAPHER, WASHINGTON D C me faire.
c'HaafLns/n. `LIrHcrow.Y or o-HIcAeo, ILLI'NoIs.
Letters Patent Naploazladaaa May 17, 1ste.
The Sched-nie referred to in these Lettera Patent and mal-.zing paxt ofthe same.
I, OHABLs H. Lrrneow, of" the city of Chicago, in the State of Illinois, have invented an `Improved Apparatus for Polishing and Securing Knives, of
` p which the following is a specification.
y My apparatusconsists, essentially, of two disks, made to rotate l in va fixed c asc o r cylinder, through the periphery of whiolivtlie knives are inserted, so that their blades are` interposed between the faces of f said disks, which4 are provided with brushes and ribs,
` `with intervening,r channels,- arrauged as hereinafter described; and
My invention consists in the manner of `constructing the disks to secure equal 'and elastic pressure of the rubbing-ribs upon the surfaces of the articles scoured,aud in `the device for insuring uniform pressure and action ofthe disks on opposite sides'of the knives at the Sametime. In the `drawing-1- i VFigure 1 is acentral'vertical section; Figure 2, a transverse vertical section; and Figure 3, a fragmentary view, showing a portion of oueot'- the disks, and theconstructon of the ribs upon their faces. t y The cylindrical case AA may be made of wood or metal, or its parts of both, andsupported upon feet B B. i i
`It has a central shaft, C, with journals passing through the sleeve-bea'rings` in the sides of the case, as `,hereinafter described.l i t This shaft carries two disks, D D, of a size nearly i filling the interior of the lease, and whichrevolve with the shaft when it is rotated by the winch E.
The disks are provided, oi their proximate faces, `with brushes f fandrubbing-ribs g g, the space occupied bythe latter being about three-fourths and the former one-fourth of the area of the disks.
The knives to be operated on are inserted radially through apertures h h. onthe rim of the case, so that i their blades liebetweeu the adjacent faces of l the disks, and `are subjected to abrasion by the brushes and ribs, which are supplied with emery, or other f suitable abrasive material, in the following manner:
A small quantity of emery is placed within the ,casie, which falls, by its'weight, to the lowest point.
Small scoops or Scrapers i i, formed of sheet metal',
are attached tof the .outer side of each disk, at the periphery, which are connected each with a passage,
` jj,1throngh the disks, opening into the space between them, ata point near'the axis, and between the brushes. lAs thedisks revolve these mouths scoop up-aiportion o'f the emery as they pass the'V bottom,
which passes through and is discharged between the brushes, and thence, distributed through the interveiling grooves between the ribs; andths operation being repeated at each revolution, a constant and equal supply is maintained. 4
lhe space containing the ribs g gis divided into triangular sections, the bases of which are radial from` the axis of the disks.
A'lhe ribs are preferablymade of leather, though felt i or other fibrous substances will answer. They are gluedv or otherwise fastened 4to the faces of the disks, and are inypart maintained in `positicm by interposed wooden strips l 'I, of -lessv projection, which are also glued vor securely fastened to the disks; .but between each of the ribs and strips'is first `placed a strip of `India rubber, m, on ille back side, relative to the di' reetionof rotation of the rib. This has the effect to support, by its elasticity, the leather rib, and cause it to maintain its position under use, while it admits of its yielding to extreme pressure.
i The-knives are inserted in the manner shown by dotted lines in figs. l and 2, their edges facing the di! rectionof rotation, and their handles supported partially'by the guards n u.
In order to maintain an equal pressure of the disks toward each other, and against the knives which lie `between their faces, each journal of the shaft is provided with a sleeve, o o, bearing at its inner endv Vagainst a shoulder on. the shaft, and its outer one against a rubber cushion, p, which yields as a spring, the amount of pressure being regulated by the' screwnuts 'r i'.
The operation `is rapid and effective, both to polish and scour knives and other edge-tools.
I claim as my invention- 1. The disks D D, provided with the brush and sectional-ribbed faces, as described, in combination with the closed case A, substantially as and for the purpose described.
J2. Forming the ribs with exible supporting-strips man, interposedbetwcen the the former an'd securingstrips l l. 1 v
3. In combination with the shaft C and disks D, the sleeve-bearings o o, cushions 11 p, and adj usfmgnuts r r, as and for the purpose set forth.
In'witnesswhereof have hereunto set my namev l in the prcsence'oif two subscribing witnesses. w CHAS. H. LITHGOW.'
