Abstract
Abstract The present invention relates to tips for a heavy-duty mixer, said tips including a left side surface, a right side surface, a leading edge, a trailing edge surface and a top edge surface interconnecting the leading and trailing edge surfaces, and a bottom edge surface interconnecting the leading and trailing edge surfaces. The tip is symmetrical about a center plane intermediate the side surfaces and carries receiving means for receiving fasteners to secure the tip to a shank which receiving means are designed to receive a fastener from either the left or the right side surface areas, thereby providing a tip interchangeable between left and right arms of the mixer.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
135 words
A tip for attachment to an arm of a heavy-duty mixer comprising: a body having a top edge surface, a leading edge surface, a trailing edge surface, a bottom edge surface and a plurality of side surfaces, a plurality of apertures protruding through the body and opening onto the side surfaces, and protective means integral with the body and adjacent to the opening on each side surface to create a protective barrier in front of the openings relative to the leading edge, said leading edge surface being tapered to form a plurality of tapered surfaces extended to form a crown, said crown being disposed in alignment with the center plane, said plane being intermediate said side surfaces and passing through the center of said body, said body being symmetrical with respect to said center plane.
Claim 2
Dependent Claim
135 words
A tip for attachment to an arm of a heavy-duty mixer comprising: a body having a top edge surface, a leading edge surface, a trailing edge surface, a bottom edge surface and a plurality of side surfaces, a plurality of apertures protruding through the body and opening onto the side surfaces, and protective means integral with the body and adjacent to the opening on each side surface to create a protective barrier in front of the openings relative to the leading edge, said leading edge surface being tapered to form a plurality of tapered surfaces extended to form a crown, said crown being disposed in alignment with the center plane, said plane being intermediate said side surfaces and passing through the center of said body, said body being symmetrical with respect to said center plane.
Claim 3
Dependent Claim
31 words
The tip of claim 1 in which the protEctive means includes a countersink at each opening, such that the head of a fastener may be countersunk relative to the side surfaces.
Claim 4
Dependent Claim
33 words
The tip of claim 1 which the protective means includes a protrusion integral with the side surfaces and adjacent each opening, the protrusion positioned intermediate the associated aperture and the leading edge surface.
Claim 5
Dependent Claim
31 words
The tip claim 3 in which the protrusion means includes a bumber integral with the leading edge surface and extending laterally beyond the side surfaces and in alignment with said apertures.
Claim 6
Dependent Claim
31 words
The tip of claim 1 in which the width of the body is tapered with the thickness of the body adjacent the trailing edge exceeding the thickness adjacent the leading edge.
Claim 7
Dependent Claim
38 words
The tip of claim 1 in which the trailing edge is tapered to form a plurality of tapered surfaces extended to form a crown, the crown of the trailing edge being disposed in alignment with said center plane.
Claim 8
Dependent Claim
34 words
The tip of claim 6 further including first edge surface portions intermediate and interengaging the leading edge and the top edge surface, said first portions establishing an acute angular relationship with the top surface.
Claim 9
Dependent Claim
34 words
The tip of claim 7 further including second edge surface portions intermediate and interengaging the trailing edge and the top edge surface, said second portions establishing an acute angular relationship with the top surface.
Claim 10
Dependent Claim
104 words
A tip for attachment to an arm of a heavy-duty mixer comprising: a body having a top edge surface, a leading edge surface, a trailing edge surface, a bottom edge surface and a plurality of side surfaces, and a plurality of apertures protruding through said body and opening onto said side surfaces, said leading edge being tapered to form a plurality of tapered surfaces extended to form a crown, said crown being disposed in alignment with a center plane, which is intermediate said side surfaces and which passes through the center of said body, said body being symmetrical with respect to said center plane.
Claim 11
Dependent Claim
104 words
A tip for attachment to an arm of a heavy-duty mixer comprising: a body having a top edge surface, a leading edge surface, a trailing edge surface, a bottom edge surface and a plurality of side surfaces, and a plurality of apertures protruding through said body and opening onto said side surfaces, said leading edge being tapered to form a plurality of tapered surfaces extended to form a crown, said crown being disposed in alignment with a center plane, which is intermediate said side surfaces and which passes through the center of said body, said body being symmetrical with respect to said center plane.
Claim 12
Dependent Claim
42 words
A tip as claimed in claim 9 in which said trailing edge is tapered to form a plurality of tapered surfaces, which are extended to form a crown, the crown of said trailing edge being disposed in alignment with said center plane.
Claim 13
Dependent Claim
37 words
A top as claimed in claim 10 and comprising first edge surface portions intermediate and interengaging said leading edge surface and said top edge surface, said first portions forming an acute angular relationship with the top surface.
Claim 14
Dependent Claim
37 words
A tip as claimed in claim 11 and comprising second edge surface portions intermediate and interengaging said trailing edge surface and said top edge surface, said second portions forming an acute angular relationship with the top surface.
