"Vintage Machinery" entry for Stover Machine Co.
Description:
"First, we claim the bar, b, constructed and arranged substantially as set forth, in combination with the rack, c, or its equivalent. Also the device for the rear end of the platen, so constructed and arranged that the dogging bars are clamped firmly to the platen, at the same time that they adjust themselves to the form and position of the end of the lumber by the operation of a single screw substantially as described."

An article in an 1860 issue of Scientific American describes this machine, and includes an engraving of it. The article notes that this planer is convertible between a Woodworth-style and a Daniels-style planer (see patent 5,315X and patent 8,548X, respectively).
