Your machine cancel was made by a machine sold by the Barr-Fyke Machine Company of Kansas City, Missouri. Another form of the machine's impression has a killer made up of horizontal bars. The presence of arcs in the dial can also be an indicator of the Barr-Fyke machine. Here is a picture of a Barr-Fyke machine impression [6k GIF].
There is a bit more information available about these machines on my Machine Web page.
