Meeting rail planes

Whelan, J M

Plane Chatter

In double-hung sash windows, the lower rail of the top sash is shaped to fit tightly with the upper rail of the bottom sash when both are closed, to provide a draft-proof seal. These are the meeting rails.

John Walkowiak provided the photograph (Figure 2) of two meeting rail planes, a rather rare type. On the left is a Sandusky no. 174. This number was used in their 1877 catalog for another sash plane,while the meeting rail plane was listed (without an outline sketch) as no. 174 1/2. The tool was not listed in their 195 catalog.

The plane on the right of Figure 2 was marked by the Ohio Tool Co., no. 135 3/4. The Ohio catalog number 23 (circa 1910) listed no. 134 1/2 as a meeting rail plane, suggesting that the tool of the figure was a variant. The unusual profile presents a problem. Was there a corresponding profile in a mating tool, or was the shape intended to be used with a weather-- strip?

The second fence on the right side (left in the photo) of each tool, it is presumed, serves to insure proper alignment of the cut by fitting the thickness of the rail being contoured.
