' VIBRATING CUTTER FOR SHEEP vSHIEIARS AND THE LIKE. i y Y Application led June 11, 1926. Serial No. 115,194.
The purpose of this invention is to provide a vibrating or reciprocating cutter or the Ilike member 'of a sheep shear of which the shear blade may be a simple fiat piece of thin steel die-cut from a sheet, of the proper contour to comprise the desired number and form of shear teeth, such sheet steel member being held fiat on the cooperating fixed cutter or comb of the tool, by a body or actuating member adapted to be engaged for actuation by suitable means comprised in the tool for the purpose, and having means for engaging the sheet steel cutting member otherwise than at the edges of the member, whereby said edges may be exposed Vclear A of the actuating member for cooperating shearwise with the edges of the teeth of the liXed shear member or comb.
The invention consists in the features and elements and construction herein shown and described, as indicated in the claims.
In the drawings Figure l is a plan view of the vibrating cutter member of a sheep shear constructed according to this invention. Y
Figure'Q is a pla-n view of the body or actuating member of such vibrating cutter.
Figure 3 is a plan view of the assembled vibrating cutter shown in operative posit-ion on the coo erating ixed cutter orV comb of the sheep s ear. u I
Figure 4 is a section at the line 4 4 1n Figure 3.
Figure 5 is a section at the line 5 5 on Figure 3.
Figure 6 is a section similar to Figure 5V on a larger scale, showing la detail. modification in the form of the shearing edges of the vibrating cutter blade.
In the drawings, A represents the cutting member of the vibrating cutter, said member being a perfectly flat piece of steel which is preferably made by cutting by a die a blank from sheet steel, whereby the edges in- Cluding the shearing edges ofthe teeth, A1,
A2, A3, are directly transverse toboth surfaces of the blank, and are thereby adapted for shearing action at both sides, so that this cutting member may be used eitherside formed with a peripheral iange, B', con-` formed in outline to the form of the cuttingy up; and when it becomes dulled at one side,
memberA, at least throughout the contour of so much'of said cutting member as com* prises the teeth, A1, A2, A3, and .dimensioned for exposingy beyond said ange, when; the body.. member is lodged upon the cutting member with the short "studs, b', A1 engaged in the aperture, a of the latter, a narrow marginal portion only of the teeth, A1, A2, A3, a projection of 10/1000, being sufficient.
n Win bo understood that tho body or` actuating member, A, is adapted for engagement for actuation by the actuating means of the tool, which is usually a vibrating lever terminating for engaging apertures in the vibrating cutter, such apertures being provided as seen in Al-Al, in the member A.
For some sorts of shearing service, a`
right-angle shearing corner may be found less efficient than a slightly acute corner,
such as would be produced by slightly bevelling the edges of teeth; and for providing such b'evelled or slightly acute edges without sacrificing the advantage ofv reversibility of the cutting blade, the edges of the teethmay be milled to form a `V`shaped groove therein, as lillustrated in the magnified view, Figurev 6. y
I claim:
l. A vibrating cutter for a sheep shear, or
the like, comprising a cutting member and an actuating member, the cutting member being thin sheet metal adapted to seat flat on the comb membe'r of the shear, the actuating member being adapted for engagement by the reciprocating means of the shear and being peripherally conformed closely to the youtline of the cutting member, and seating thereon along the cutting edges of the latter, 'i
said two members having cooperating features for actuating engagement of the cutting member by the other. v
2. In the constructiondefined in claim 1, the cutting member being devoid of defiection either upward or downward from its plane, whereby it is equally adapted to be sharpened on either side.
3. In the construction defined in claim 1, the cutting member being die-cut from metal sheet and devoid of deflections from its plane toward either side; whereby it is rendered reversible-for utilizing the intersection of either face with the peripheral edge for eooperating shearwisewith the comb teeth.
4. In the construction defined in claim l,
the vibrating blad-e having an odd number of teeth all radiating in an are about the axis of vibration and being symmetrical about the middle line of the middle tooth, the lateral teeth ofboth sides being each rendered non-symmetrical by having their opposite cutting edges differently inclined to the radial line through the apex, the edge toward the side of the middle tooth being more nearly radial than the outer edge.v
5. In the construction defined in claim l, the cutting member having apertures for engagement by projections from the' actuating member, said member having downwardly projecting studs for engaging said apertures for vibrating the cutting member.
In testimony whereof, I havev hereunto set my hand at Chicago, Illinois, this 8th day of f June, 1926. y
