Abstract
Abstract A bed of a lathe comprises a concrete base block and a metal body provided with guide ways for guiding movable lathe elements such as bed slides or the like. The guide-ways are formed by horizontal parallel grooves provided in the front face of the metal body, each groove having opposite side walls and a bottom wall. The metal body has a bottom face fixed on a conforming top surface of the concrete block by a plastic adhesive which constitutes the sole and exclusive means for transferring forces between the metal body and the concrete block.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A bed of a lathe comprising portable base formed by a compact block of concrete having a supporting top face, a metal body resting on said face and provided with guideways for guiding movable lathe elements and with a bottom face conforming to and co-extensive with said supporting top face, said metal body being mounted on said base with said faces in opposed and closely adjacent relationship, and a thin layer of an adhesive plastic filling the space between said faces for rigidly cementing said metal body to said concrete base, whereby oscillations of said bottom surface are impeded by the non-oscillating concrete material of said block cemented thereto by said adhesive.
Claim 2
Dependent Claim
112 words
A bed of a lathe comprising portable base formed by a compact block of concrete having a supporting top face, a metal body resting on said face and provided with guideways for guiding movable lathe elements and with a bottom face conforming to and co-extensive with said supporting top face, said metal body being mounted on said base with said faces in opposed and closely adjacent relationship, and a thin layer of an adhesive plastic filling the space between said faces for rigidly cementing said metal body to said concrete base, whereby oscillations of said bottom surface are impeded by the non-oscillating concrete material of said block cemented thereto by said adhesive.
Claim 3
Dependent Claim
29 words
A bed as claimed in claim 1 in which said layer constitutes the only and exclusive means for the transfer of forces from said metal body to said base.
Claim 4
Dependent Claim
24 words
A bed as claimed in claim 1 in which said metal body is hollow, consists of cast iron and is filled with core material.
Claim 5
Dependent Claim
33 words
A bed as claimed in claim 1 in which said guideways are formed by parallel grooves, each of which has parallel side faces and a bottom face extending transversely to said side faces.
Claim 6
Dependent Claim
53 words
A bed as claimed in claim 1 in which said metal body has a front face extending substantially at right angles to said bottom face and being provided with horizontal parallel grooves constituting said guideways, each groove having parallel side faces and a bottom face, said metal body side face being slightly inclined.
