Driver with External Torque Value Indicator Integrated with Spindle Lock and Related Method
First Claim
1. A power tool comprising:
- a housing;
a motor assembly connected to a transmission assembly, wherein said motor assembly and said transmission assembly are secured against rotation in the housing;
a plurality of protrusions that extend from a component of said transmission assembly;
an output spindle;
a spindle lock assembly that connects said output spindle to said transmission assembly, said spindle lock assembly includes an anvil, an outer ring member and a plurality of roller members, wherein said roller members and said protrusions are disposed between said anvil and said outer ring member;
an indicator member that extends from said outer ring member;
a compliant member that connects said outer ring member to an interior portion of said housing; and
a scale connected to an exterior portion of said housing, wherein said indicator member moves relative to said scale to indicate a value of torque at said output spindle.

Abstract
A power tool generally includes a housing and a motor assembly connected to a transmission assembly. The motor assembly and the transmission assembly are secured against rotation in the housing. A plurality of protrusions extends from a component of the transmission assembly. The power tool further includes an output spindle and a spindle lock assembly that connects the output spindle to the transmission assembly. The spindle lock assembly includes an anvil, an outer ring member and a plurality of roller members. The roller members and the protrusions are disposed between the anvil and the outer ring member. An indicator member extends from the outer ring member. A compliant member connects the outer ring member to an interior portion of the housing. A scale is connected to an exterior portion of the housing, wherein the indicator member moves relative to the scale to indicate a value of torque at the output spindle.
