Abstract
Abstract A cutting tool is carried by a carriage which is slidably engaged by a rotatable body connected to a drive shaft so that the body and carriage rotate together to perform boring and facing operations. The rotational movement of the body relative to a reference member produces transverse sliding movement of the carriage relative to the body, thereby increasing the diameter of the circular path followed by the cutting tool. The ratio of transverse movement of the carriage to rotational movement of the body can be altered by rotating the reference member. A mechanism which includes a plurality of carriage stops is provided for arresting the transverse movement of the carriage. This mechanism is indexed by the movement of the carriage to bring successive stops into operative position in sequence.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
233 words
A boring and facing apparatus comprising a body adapted to be connected to a drive shaft for rotation therewith, a carriage slidably carried by the body for rotation with and transverse movement relative to the body, means on the carriage for mounting a tool, a reference member mounted on the body for rotation relative to the body, gear means associated with the body, reference member, and carriage for driving the carriage transversely relative to the body upon rotational movement of the body relative to the reference member, and means coupled to the reference member for rotating it to provide movement of the carriage relative to the body proportional to the difference between the rotational speeds of the body and the reference member, said means for rotAting the reference member being an electric motor including first and second annular magnetic elements arranged concentrically and co-operating with each other, the inner one of the magnetic elements being rotatably mounted on the drive shaft above the reference member, at least one of the magnetic elements being an electromagnet and being connected to an electric power supply whereby the difference between the rotational speeds of the body and the reference member is determined by the output voltage of the power supply and one of the magnetic elements being rotatable relative to the other and being coupled to the reference member for rotation of the reference member therewith.
Claim 2
Dependent Claim
233 words
A boring and facing apparatus comprising a body adapted to be connected to a drive shaft for rotation therewith, a carriage slidably carried by the body for rotation with and transverse movement relative to the body, means on the carriage for mounting a tool, a reference member mounted on the body for rotation relative to the body, gear means associated with the body, reference member, and carriage for driving the carriage transversely relative to the body upon rotational movement of the body relative to the reference member, and means coupled to the reference member for rotating it to provide movement of the carriage relative to the body proportional to the difference between the rotational speeds of the body and the reference member, said means for rotAting the reference member being an electric motor including first and second annular magnetic elements arranged concentrically and co-operating with each other, the inner one of the magnetic elements being rotatably mounted on the drive shaft above the reference member, at least one of the magnetic elements being an electromagnet and being connected to an electric power supply whereby the difference between the rotational speeds of the body and the reference member is determined by the output voltage of the power supply and one of the magnetic elements being rotatable relative to the other and being coupled to the reference member for rotation of the reference member therewith.
Claim 3
Dependent Claim
26 words
The apparatus set forth in claim 1 wherein the means for rotating the reference member is capable of continuously varying its speed over a substantial range.
Claim 4
Dependent Claim
27 words
The apparatus set forth in claim 1 wherein the means for rotating the reference member is capable of rotating it at a plurality of substantially different speeds.
Claim 5
Dependent Claim
17 words
The apparatus set forth in claim 1 wherein one of the magnetic elements is a permanent magnet.
Claim 6
Dependent Claim
213 words
A boring and facing apparatus comprising a body adapted to be connected to a drive shaft for rotation therewith, a carriage slidably carried by the body for rotation with and transverse movement relative to the body, means on the carriage for mounting a tool, a reference member mounted on the body for rotation relative to the body, gear means associated with the body, reference member, and carriage for driving the carriage transversely relative to the body upon rotational movement of the body relative to the reference member, and means coupled to the reference member for rotating it to provide movement of the carriage relative to the body proportional to the difference between the rotational speeds of the body and the reference member, including a first magnetic element which is an electromagnet and is rotatably mounted about the drive shaft and above the top of the body, a second magnetic element which surrounds the first magnetic element and is supported in a fixed position by a stationary frame, and a sleeve disposed between the drive shaft and the first magnetic element, the sleeve connecting the first magnetic element to the reference member for rotation therewith whereby the two magnetic elements coact to form an electric motor and produce rotary motion of the reference member.
Claim 7
Dependent Claim
213 words
A boring and facing apparatus comprising a body adapted to be connected to a drive shaft for rotation therewith, a carriage slidably carried by the body for rotation with and transverse movement relative to the body, means on the carriage for mounting a tool, a reference member mounted on the body for rotation relative to the body, gear means associated with the body, reference member, and carriage for driving the carriage transversely relative to the body upon rotational movement of the body relative to the reference member, and means coupled to the reference member for rotating it to provide movement of the carriage relative to the body proportional to the difference between the rotational speeds of the body and the reference member, including a first magnetic element which is an electromagnet and is rotatably mounted about the drive shaft and above the top of the body, a second magnetic element which surrounds the first magnetic element and is supported in a fixed position by a stationary frame, and a sleeve disposed between the drive shaft and the first magnetic element, the sleeve connecting the first magnetic element to the reference member for rotation therewith whereby the two magnetic elements coact to form an electric motor and produce rotary motion of the reference member.
Claim 8
Dependent Claim
16 words
The apparatus as set forth in claim 5 wherein the second magnetic element is permanently magnetized.
Claim 9

The apparatus set forth in claim 1 and further comprising a carriage-arresting mechanism, the boring and facing apparatus further comprising an abutment for engaging the carriage-arresting mechanism, the carriage-arresting mechanism comprising a plurality of carriage-arresting stops arranged to be positioned in sequence for engagement by the abutment, a movable stop-supporting member that carries the stops, and a means for indexing the stop-supporting member to bring each successive stop into position to be engaged by the abutment in response to the transverse movement of the carriage.
Claim 10
Dependent Claim
82 words
The apparatus set forth in claim 1 wherein the motor is a variable-voltage, direct-current motor and wherein the means for controlling the rotational speed of the reference member further includes means for monitoring the rotational speed of the reference member and producing a signal indicative thereof and means receiving said signal and producing a control signal and conducting such control signal to the power supply of the motor to vary the voltage supply to the motor in accordance with said speed signal.
Claim 11
Dependent Claim
