Abstract
Abstract A bar stock feeding assembly and a vibration damping support block for use therein. An elongated housing is provided with a plurality of internal blocks to support a bar stock being fed to a machine tool. Each support block is provided with a central opening slidably receiving the bar stock, and a plurality of legs extending outwardly into engagement with the internal wall of the housing to position the block in relation to the housing. At least the legs of the block are formed of resilient material such as rubber or plastic so that vibration of the bar stock, while being acted on by the machine tool, is not transmitted to the housing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
86 words
An assembly for feeding bar stock into a machine tool, comprising an elongated feeder housing of non-circular internal cross-section and a plurality of blocks disposed in said housing, said blocks each having a central aperture to slidably receive the bar stock, and a series of outwardly extending portions comprised of vibration damping material positioned and dimensioned for engaging the interior of the feeder housing to prevent vibration of the bar stock from being transmitted to the housing and to render the block non-rotatable in the housing.
Claim 2
Dependent Claim
86 words
An assembly for feeding bar stock into a machine tool, comprising an elongated feeder housing of non-circular internal cross-section and a plurality of blocks disposed in said housing, said blocks each having a central aperture to slidably receive the bar stock, and a series of outwardly extending portions comprised of vibration damping material positioned and dimensioned for engaging the interior of the feeder housing to prevent vibration of the bar stock from being transmitted to the housing and to render the block non-rotatable in the housing.
Claim 3
Dependent Claim
38 words
An assembly as set out in claim 1 in which each of said blocks has a slot opening from the exterior to the central opening said slots being aligned to allow a stock feeding mechanism to travel therethrough.
Claim 4
Dependent Claim
73 words
A vibration absorbing block for assembly into an elongated feeder housing of non-circular internal cross-section for bar stock, said block having a central opening for slidably receiving the bar stock, and a plurality of resilient legs extending from the block to engage the interior surface of the feeder housing to non-rotatably position the block in relation to the housing and to prevent vibration of the bar stock from being transmitted to the housing.
Claim 5
Dependent Claim
73 words
A vibration absorbing block for assembly into an elongated feeder housing of non-circular internal cross-section for bar stock, said block having a central opening for slidably receiving the bar stock, and a plurality of resilient legs extending from the block to engage the interior surface of the feeder housing to non-rotatably position the block in relation to the housing and to prevent vibration of the bar stock from being transmitted to the housing.
Claim 6
Dependent Claim
30 words
A block as set out in claim 3 in which said block has 4 legs extending therefrom in directions so as to seat in 4 corners of a rectangular housing.
Claim 7
Dependent Claim
30 words
A block as set forth in claim 3 which has a slot opening to the central opening and axially aligned therewith to allow a stock feeding mechanism to travel therethrough.
