Abstract
Abstract Machine tool structure designed to reduce the noise incident to operation. The invention is illustrated and described as applied to a vertical broaching machine in which the frame structure is modified by supporting the operating components on a vertical slab or thick plate reinforced with longitudinally extending ribs and including an open truss type support rather than the conventional hollow or enclosed columnar frame in common use.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
119 words
A machine tool characterized in minimal noise production during operation, said tool having a generally rectangular, heavy, solid, unitary, metal, slab-like main support plate, rib means integrally secured to one side of said plate and extending from one transverse edge at least substantially to the opposite edge of said plate and spaced inwardly from the remaining longitudinal edges of said plate, a first machine component rigidly secured to one side of said plate, an open truss-like frame structure connected to said plate, and said frame structure including means extending to the bottom of said plate to provide support for said plate directly from a supporting floor, and a second machine tool component in operative juxtaposition to said first component.
Claim 2
Dependent Claim
119 words
A machine tool characterized in minimal noise production during operation, said tool having a generally rectangular, heavy, solid, unitary, metal, slab-like main support plate, rib means integrally secured to one side of said plate and extending from one transverse edge at least substantially to the opposite edge of said plate and spaced inwardly from the remaining longitudinal edges of said plate, a first machine component rigidly secured to one side of said plate, an open truss-like frame structure connected to said plate, and said frame structure including means extending to the bottom of said plate to provide support for said plate directly from a supporting floor, and a second machine tool component in operative juxtaposition to said first component.
Claim 3
Dependent Claim
30 words
A machine tool as defined in claim 1 in which said machine tool is a metal cutting tool, and said components are a work support and a cutting tool support.
Claim 4
Dependent Claim
48 words
A machine tool as defined in claim 1 in which said machine tool is a broaching machine, one of said components being a broaching tool, the other of said components being a work support, and means for effecting relative movement between said components longitudinally of said broaching tool.
Claim 5
Dependent Claim
19 words
A machine tool as defined in claim 3 in which said broaching tool is fixed to said slab-like plate.
Claim 6
Dependent Claim
33 words
A machine tool as defined in claim 4 in which said second component is a movable work support, and actuating and guide means connected directly between said plate and said movable work support.
Claim 7
Dependent Claim
56 words
A machine tool as defined in claim 5 in which the means connecting said actuating and guide means to said plate comprises a pair of spaced secondary support plates rigidly connected at their edges to said main support plate to extend laterally therefrom, said actuating and guide means being rigidly connected to said secondary support plates.
Claim 8
Dependent Claim
32 words
A machine tool as defined in claim 6 in which said main plate is vertical, said secondary plates being connected to said main plate adjacent its lower end and extending horizontally therefrom.
Claim 9
Dependent Claim
85 words
A machine tool as defined in claim 7, said frame structure comprising base plates, said rib means comprising a pair of ribs extending below said main plate to said base plates are rigidly secured thereto throughout their lower edges, and vertically elongated flat frame elements rigidly secured at their upper edges to said secondary support plates, at their lower edges to said base plates, and at vertically extending side edges thereof to the portions of said ribs below the lower edge of said main plate.
Claim 10
Dependent Claim
43 words
A machine tool as defined in claim 2, said main support plate being vertical, a pair of laterally spaced secondary support plates rigidly connected to said main plate adjacent its lower edge, and means connecting said second component to said pair of plates.
Claim 11
Dependent Claim
47 words
A machine tool as defined in claim 9, said frame comprising base plate means, said rib means comprising a pair of vertically extending ribs the lower ends of which extend below the lower edge of said main plate and are rigidly secured to said base plate means.
Claim 12
Dependent Claim
63 words
A machine tool as defined in claim 10, said frame including support structure for said secondary plates comprising vertically elongated flat frame elements rigidly secured at their upper edges to said secondary support plates, at their lower edges to said base plates, and at vertically extending side edges thereof to the portions of said ribs below the lower edge of said main plate.
Claim 13
Dependent Claim
35 words
A machine tool as defined in claim 2, in which said main plate has a thickness of about 21/2 inches, and said rib means are of materially different thicknesses from that of said main plate.
Claim 14
Dependent Claim
36 words
A machine tool as defined in claim 9 in which said main plate has a thickness of about 21/2 inches, and said secondary support plates are of materially different thickness from that of said main plate.
Claim 15
Dependent Claim
30 words
A machine tool as defined in claim 2 in which said main support plate has a thickness of at least 2 inches and a width of at least 2 feet.
Claim 16
Dependent Claim
34 words
A machine tool as defined in claim 2 in which said first machine component is secured to the side of said main support plate opposite the side to which said rib means are secured.
