Abstract
Abstract A cutting tool coolant supply system for a machine tool wherein coolant is supplied to the cutting area through mating internal passages formed in the tool support member, such as the ram of a vertical lathe, and the tool adapter. A sealing ring is provided in the lower end of the tool support member for engaging the radial flange of the tool adapter to facilitate automatic and reliable coupling of the internal passages when the adapter is positioned in the support member for a machining operation.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
225 words
In a machine tool having a tool support with a socket in one end thereof for removably receiving and supporting a cutting tool adapter having a shank shaped complementary to said socket and an outwardly extenDing radial flange with a surface perpendicular to the longitudinal axis of said tool adapter, said socket and shank each having bearing surfaces that are mutually engageable when said tool adapter is secured in said support for a machining operation, a cutting tool coolant supply system comprising a coolant reservoir, said support being formed with a longitudinal internal passage having an inlet and an outlet, means connecting said passage inlet to said coolant reservoir, said passage outlet being located in the end of said support at a laterally offset position from said socket, said tool adapter being formed with an internal passage having an inlet on said radial flange surface at a position aligned with said support passage when said tool adapter is secured in said support, said tool adapter passage extending from said radial flange inlet to an outlet in close proximity to the cutting tool of said adapter, means for selectively supplying coolant from said coolant reservoir through said support and tool adapter passage during a machine operation, and means for directing the flow of coolant from said adapter passage outlet onto the cutting tool of said adapter.
Claim 2
Dependent Claim
225 words
In a machine tool having a tool support with a socket in one end thereof for removably receiving and supporting a cutting tool adapter having a shank shaped complementary to said socket and an outwardly extenDing radial flange with a surface perpendicular to the longitudinal axis of said tool adapter, said socket and shank each having bearing surfaces that are mutually engageable when said tool adapter is secured in said support for a machining operation, a cutting tool coolant supply system comprising a coolant reservoir, said support being formed with a longitudinal internal passage having an inlet and an outlet, means connecting said passage inlet to said coolant reservoir, said passage outlet being located in the end of said support at a laterally offset position from said socket, said tool adapter being formed with an internal passage having an inlet on said radial flange surface at a position aligned with said support passage when said tool adapter is secured in said support, said tool adapter passage extending from said radial flange inlet to an outlet in close proximity to the cutting tool of said adapter, means for selectively supplying coolant from said coolant reservoir through said support and tool adapter passage during a machine operation, and means for directing the flow of coolant from said adapter passage outlet onto the cutting tool of said adapter.
Claim 3
Dependent Claim
42 words
In the machine tool of claim 1 including a sealing member at the end of said support passage for forming a liquid tight coupling between said passage and said tool adapter passage when said tool adapter is secured in said support socket.
Claim 4
Dependent Claim
45 words
In the machine tool of claim 2 in which said sealing member is a flexible ring secured within said support passage with a portion thereof extending beyond the end of said support for engaging the said tool adapter flange surface about said adapter passage inlet.
Claim 5
Dependent Claim
72 words
In the machine tool of claim 1 in which said tool adapter passage includes a longitudinally directed passage extending into said gripping flange from said adapter passage inlet, a radial passage extending inwardly from said longitudinal passage, a second longitudinal passage extending from said radial passage to a location near an end of said tool adapter, and a second radial passage extending from said second longitudinal passage to said adapter passage outlet.
Claim 6
Dependent Claim
35 words
In the machine tool of claim 1 in which said coolant directing means includes a rigid conduit connected at said tool adapter outlet and extending to a position in predetermined relation to said cutting tool.
Claim 7
Dependent Claim

In the machine tool of claim 1 in which said tool support is the selectively positionable ram of a lathe.
Claim 8
Dependent Claim
206 words
A cutting tool adapter for use in a machine tool having a tool support formed with a socket in one end and an internal coolant supply passage extending to an outlet in said support end at a laterally offset position from said socket comprising a shank portion shaped complementary to said tool support socket for selective bearing engagement with said socket, a tool head portion at an end opposite said shank portion, means in said head portion for securing at least one cutting tool, a radially extending flange located intermediate said shank and head portions, said flange having a surface on the shank side thereof that is perpendicular to the longitudinal axis of said adapter for positioning adjacent said tool support end when said shank is placed in said support socket, said tool adapter being formed with an internal passage having an inlet on said radial flange surface that is aligned with said support passage when said radial flange is placed adjacent said support end, said tool adapter passage extending from said radial flange inlet to an outlet in close proximity to the cutting tool of said adapter, and means for directing coolant supplied to said adapter passage from said passage outlet onto said cutting tool.
Claim 9
Dependent Claim
206 words
A cutting tool adapter for use in a machine tool having a tool support formed with a socket in one end and an internal coolant supply passage extending to an outlet in said support end at a laterally offset position from said socket comprising a shank portion shaped complementary to said tool support socket for selective bearing engagement with said socket, a tool head portion at an end opposite said shank portion, means in said head portion for securing at least one cutting tool, a radially extending flange located intermediate said shank and head portions, said flange having a surface on the shank side thereof that is perpendicular to the longitudinal axis of said adapter for positioning adjacent said tool support end when said shank is placed in said support socket, said tool adapter being formed with an internal passage having an inlet on said radial flange surface that is aligned with said support passage when said radial flange is placed adjacent said support end, said tool adapter passage extending from said radial flange inlet to an outlet in close proximity to the cutting tool of said adapter, and means for directing coolant supplied to said adapter passage from said passage outlet onto said cutting tool.
