Body Glass Details & Specifications

Both single thickness plate glass and laminated safety glass were used for side and rear windows in the Model A and B era.

Shown below are some of the details of the glass construction and marking for both styles of glass, and for both Model A and Model B.

Model A and Model B glass drawings specified different thicknesses.

Pictured above is the detail construction for Model A laminated safety glass formed by the bonding of two pieces of plate glass with a celluloid layer in the middle.

Also shown is the specification and placement of the black edge sealer to protect the celluloid.

The Model A laminated safety glass thickness tolerance is shown as 0.200 to 0.268 inches.

Pictured above is the detail for the placement of the laminated safety glass logo on the 1930-31 coupe quarter window glass drawing.

Shown above is the typical square edge construction for stationary plate glass edges which are set in rubber seals such as rear window glass.

Also shown is the Model A plate glass thickness tolerance of 5/32 to 9/32 of an inch.

This is the 1932 Model B laminated safety glass details. This shows type, style, and placement of the glass logo, or "bug".

Also noted is the description of how the logo was to be applied to the glass.

Pictured above is the typical construction for Model B laminated safety glass.

The thickness tolerance for Model B laminated safety glass is shown as 0.218 to 0.281 inches.

The chamfered edge shown is typical on the bottoms of the movable glass where it is seated in the metal regulator channel. This is also typical for Model A movable laminated safety glass.

Section A-A above shows the Model B glass edge treatment for movable laminated safety glass. This is also typical for Model A movable laminated safety glass.

The radiused edge was specified for the top edge and the side edges which move in the felt window channels. This radiused edge is both ground and polished.

This picture above shows the 1932 Model B glass edge treatment for movable plate glass. This is also typical for Model A movable plate glass.

For Model B plate glass, the thickness tolerance is shown as 7/32 to 9/32 inches.

The radiused edge shown in Section A-A was specified for the top edge and the side edges which move in the felt window channels. This radiused edge is both ground and polished.

The chamfered edge shown in Section B-B is typical on the bottoms of movable glass where it is seated in the metal regulator channel.
