Abstract
Abstract A knife block and looper mounting block having a plurality of grooved retaining plates positioned between and joined to the flanges of a body member. At least certain of the retaining plates have slots in the upper surface for receiving a clamping member for acting on the gauge parts. A multi-knife mounting block has the grooves of adjacent plates progressively disposed closer to one of the flanges and further than the other to correct for disalignment due to the rise in pitch angle between the knives and loopers.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
155 words
A mounting block for a tufting machine for carrying a plurality of gauge parts each having an elongated mounting portion of substantially rectangular cross section, said block comprising a unitary body member having a pair of elongated substantially parallel spaced flanges, a plurality of elongated retaining plates having a pair of elongated surfaces spaced apart by a distance substantially equal to the spacing between said flanges, and elongated front and rear faces joining said surfaces, an elongated rectangular groove formed in each of the rear faces, the cross section of each groove corresponding to that of the mounting portion of said gauge parts, each of said retaining plates being disposed in seriatim intermediate and abutting said flanges, the front face of the plates abutting the rear face of the adjacent plate to define a plurality of enclosed elongated rectangular channels for receiving said gauge parts, and means for securing said gauge parts in respective channels.
Claim 2
Dependent Claim
155 words
A mounting block for a tufting machine for carrying a plurality of gauge parts each having an elongated mounting portion of substantially rectangular cross section, said block comprising a unitary body member having a pair of elongated substantially parallel spaced flanges, a plurality of elongated retaining plates having a pair of elongated surfaces spaced apart by a distance substantially equal to the spacing between said flanges, and elongated front and rear faces joining said surfaces, an elongated rectangular groove formed in each of the rear faces, the cross section of each groove corresponding to that of the mounting portion of said gauge parts, each of said retaining plates being disposed in seriatim intermediate and abutting said flanges, the front face of the plates abutting the rear face of the adjacent plate to define a plurality of enclosed elongated rectangular channels for receiving said gauge parts, and means for securing said gauge parts in respective channels.
Claim 3
Dependent Claim
53 words
A mounting block as recited in claim 1 wherein said body member includes an elongated substantially centrally disposed web integral with and interconnecting said flanges, said web having a thickness substantially equal to the difference between the thickness of said plates between said front and rear faces and the depth of said channel.
Claim 4
Dependent Claim
38 words
A mounting block as recited in claim 2 wherein substantially half of said plates are disposed on each side of said web, the rear faces of the plates adjacent said web being in abutting relationship with said web.
Claim 5
Dependent Claim
47 words
A mounting block as recited in claim 1 wherein the channels in adjacent plates are progressively disposed further from one of said flanges and closer to the other such that a plane passing through corresponding points in adjacent channels is disposed at an angle to said flanges.
Claim 6
Dependent Claim
17 words
A mounting block as recited in claim 4 wherein said angle is approximately 3 to 5 degrees.
Claim 7
Dependent Claim
122 words
A mounting block as recited in claim 3 wherein the plates disposed furthest from said web, defined as end plates, have a thickness from the front face to the rear face of substantially one-half the sum of the thickness of each of the other plates between said front and rear faces and the depth of each of said channels, at least said end plates have a slot formed in one of said elongated surfaces, said means for securing said gauge parts includes a clamping member positioned in said slot and having means adapted to engage the mounting portion of the gauge part in said channel, and means for forcing said clamping member toward said gauge part and for securing said clamping member.
Claim 8
Dependent Claim
34 words
A mounting block as recited in claim 1 wherein said body member includes a laterally disposed web integral with and interconnecting said flanges, said plates being disposed in planes substantially normal to said web.
Claim 9
Dependent Claim
90 words
A mounting block as recited in claim 7 wherein said body member has a finite width, an end plate disposed on one extremity having the rear face facing outwardly from the remaining plates of said body member, the thickness of said end plate from the front face to the rear face being less than the thickness of each of the other plates, the other extremity having a capping piece of a thickness substantially equal to the difference between the thickness of each of said other plates and said end plate.
Claim 10
Dependent Claim
101 words
A mounting block as recited in claim 8 wherein said means for securing said gauge parts includes a slot formed in one of said longitudinally extending surfaces in said end plate, and a slot formed in a parallel surface of said capping piece, and the plate adjacent thereto, a clamping member positioned in each slot and having means adapted to engage the mounting portion of the gauge part in the channel in the end plate and in the plate adjacent the capping piece, and means for forcing said clamping members toward the respective gauge parts and for securing the clamping members.
