Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
The combination of a shanked tool and a holder therefor, said holder having a socket for receiving the shank of the tool and a latch resiliently biased in a direction transverse to the operating direction of the tool to engage in a recess in said shank and thereby retain the tool in the holder, the latch comprising a member having parts disposed on opposite sides of the socket and connected by at least one intermediate portion, one of which parts resiliently biases the other part to engage in said recess.
Claim 2
Dependent Claim
90 words
The combination of a shanked tool and a holder therefor, said holder having a socket for receiving the shank of the tool and a latch resiliently biased in a direction transverse to the operating direction of the tool to engage in a recess in said shank and thereby retain the tool in the holder, the latch comprising a member having parts disposed on opposite sides of the socket and connected by at least one intermediate portion, one of which parts resiliently biases the other part to engage in said recess.
Claim 3
Dependent Claim
15 words
The combination according to claim 1, wherein the latch is biassed by an elastomeric member.
Claim 4
Dependent Claim
23 words
The combination according to claim 1, wherein the recess is a groove extending across the whole of a side face of the shank.
Claim 5
Dependent Claim
21 words
The combination of claim 1, wherein the latch member comprises an endless member mounted to surround the shank in the socket.
Claim 6
Dependent Claim
40 words
The combination according to claim 1, wherein the shank and socket are of rectangular cross-section with a greater cross sectional dimension in the operating direction of the tool, whereby said recess is disposed in a wider face of the shank.
Claim 7
Dependent Claim
24 words
The combination according to claim 5 wherein the wider face has a substantial flat socket engaging area below as well as above its recess.
Claim 8
Dependent Claim
30 words
The combination according to claim 1, wherein the recess is so shaped and the latch so formed that the latch exerts a wedging action between the shank and the holder.
Claim 9
Dependent Claim
35 words

Claim 10
Dependent Claim
68 words
A tool for use in a combination as claimed in claim 1, wherein the tool has a shank of rectangular cross-section for mounting in the socket in a holder, and a head with a leading cutting part arranged to cut in a given direction relative to the shank, the shank having a latching recess in the form of a groove extending across the side face of the shank.
Claim 11
Dependent Claim
82 words
A latch for use in a holder having a socket for receiving the shank of a tool and a latch resiliently biased in a direction transverse to the operating direction of the holder to lie at least partly in said socket, said latch comprising member having parts adapted to be disposed on opposite sides of a socket in the holder and connected by an intermediate portion, and a resilient member adapted to be disposed between one of said parts and the holder.
Claim 12
Dependent Claim
82 words
A latch for use in a holder having a socket for receiving the shank of a tool and a latch resiliently biased in a direction transverse to the operating direction of the holder to lie at least partly in said socket, said latch comprising member having parts adapted to be disposed on opposite sides of a socket in the holder and connected by an intermediate portion, and a resilient member adapted to be disposed between one of said parts and the holder.
