Abstract
Abstract A tool carrier which is adapted to be arranged on a ram or work spindle of a processing machine, particularly a machine tool, comprises a tool carrier formed as a laterally opened slot of the work spindle and including a slideable member which reciprocates in a bore overlying the outer end of the slot and closes the outer end to hold the tool in a position when it is lowered alongside the tool. The slot is advantageously provided with a projection in the form of an engagement ledge which fits under a recessed end of the tool in order to hold it in position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A tool carrier adapted to be arranged on, or formed as part of, a tool holder member such as a ram, work spindle, etc., of a processing machine particularly a machine tool, comprising a tool holder member having a lower end with a slot opening laterally and downwardly and forming a tool engagement recess, said tool holder member having a bore above the lateral outer portion of the slot, and a tool holder slide moveable in the bore between a lower tool holding position, in which it closes the lateral opening of the slot around a tool positioned therein and holds the tool in position within the slot, and an upper position in which it is withdrawn from the slot and opens it laterally.
Claim 2
Dependent Claim
124 words
A tool carrier adapted to be arranged on, or formed as part of, a tool holder member such as a ram, work spindle, etc., of a processing machine particularly a machine tool, comprising a tool holder member having a lower end with a slot opening laterally and downwardly and forming a tool engagement recess, said tool holder member having a bore above the lateral outer portion of the slot, and a tool holder slide moveable in the bore between a lower tool holding position, in which it closes the lateral opening of the slot around a tool positioned therein and holds the tool in position within the slot, and an upper position in which it is withdrawn from the slot and opens it laterally.
Claim 3
Dependent Claim
32 words
A tool carrier according to claim 1, including a fastening shaft for a tool engaged in the recess, said tool holder slide having a part exerting radial pressure on said fastening shaft.
Claim 4
Dependent Claim
38 words
A tool carrier according to claim 2, wherein said fastening shaft has an annular recess, the slot of said tool holder slide having an inner wall with a projection engaged in the annular recess of the fastening shaft.
Claim 5
Dependent Claim
93 words
A tool carrier according to claim 1, wherein said tool holder member includes a wall at the interior of the slot forming a projecting shoulder extending perpendicular to the axis of said holder, a fastening shaft for a tool having an annular recess extending inwardly to the axis of said shaft and perpendicular to the axis of said tool holder member and which is engaged by said projecting shoulder to hold shaft against withdrawal downwardly, said tool holder slide having a part bearing against said fastening shaft and acting in a radial direction.
Claim 6
Dependent Claim
38 words
A tool carrier according to claim 1, wherein said tool holder slide is of a diameter greater than the diameter of said slot, said slot being widened in the area underlying the bore for said tool holder member.
Claim 7
Dependent Claim
38 words
A tool carrier according to claim 5, wherein said tool holder slide has a circular cross section, said slot having a circular guide groove on each side thereof forming and extension of the bore of said tool holder.
Claim 8
Dependent Claim
73 words
A tool carrier according to claim 1, wherein said tool holder slide comprises a first part slidable in the bore and a second part carried at the lower end of said first part and being slidably connected thereto permitting relative movement of said second part in respect to said first part obliquely to the axis of said first part, said second part being engageable with the workpiece to apply radial inward pressure thereto.
Claim 9
Dependent Claim
74 words
A tool carrier according to claim 7, wherein said second part includes a laterally extending pin at each side, said slot having a groove extending vertically therealong on each side accommodating the respective pins, the size of the groove limiting the movement of said second part with said first part and permitting relative displacement of said second part relative to said first part when the pins move to the end of the associated grooves.
Claim 10
Dependent Claim
22 words
A tool carrier according to claim 7, wherein said first and second parts have a dovetail connection therebetween permitting relative sliding movement.
Claim 11
Dependent Claim
