In the mid to late 1920s the Crowe Manufacturing Corp., also known as Crowe Safety Saw Co., Inc., established by John M. Crowe, manufactured handheld circular saws that emphasized safety and were marketed to railways and stone yards. In 1927 Ingersoll-Rand Co. announced a new line of pneumatically powered portable circular saws that used the Crowe safety guard patents under license, and examples of these saws have been seen bearing those patent dates.

In 1929 Crowe Manufacturing went under and patent rights were sold to Stanley Electric Tool Co. and Skilsaw, Inc.
