Sargent #700 series of Automatic planes, known as the Auto-Set planes. Another patent 1151301 also covers these planes. The Auto-set series have a complex adjuster mechanism that permits the blade to be kept at a constant depth setting before and after sharpening. The blades on Auto-set planes are very thin, and not nearly as robust as regular blades. Replacement blades are very hard to find. Planes in this series were available in sizes 707 through 722, (wherein the last two digits correspond to the length of the plane, similar to Millers Falls), and included a corrugation option. The planes have a distinctive profile with a sloping side. From 1916 to 1924 the tote and knob were East India Mahogany, and from 1925 to 1947 they are listed as mahogany. Dave Heckel in "Sargent Planes - Identification and Value Guide" states that the VBM era (until 1918) Auto-sets have vertical knurling on the screws, and later era planes have diamond-shaped knurling. He reports an early variation having a levercap with a triangular shaped piece to control the cutter depth setting. It has markings of 1-2-3 to indicate depth setting. The levercap acts as a chipbreaker. The longer models of the Auto-Set planes (Nos. 718 and 722) are equipped with a tilting front knob described as, "high, to give a full grip for the hand and is adjustable so that the user my regulate the position of the Knob, bringing it closer to the handle or further away, as he may prefer. This feature makes it convenient for use by carpenters with long or short arms and allows fhe forward hand plenty of clearance when the Plane is used close up to a projecting surface." This design precedes the Gage auto-set design, and is sometimes confused with it.

Manufactured by Spear & Jackson - Cincinnati OH

The plane has a sole of a number of strips of bone or ivory. The strips may also be of any organic matter. Regarding the plane is image no. 2: ADJUSTABLE COFFIN PLANE. J. Katz Patent. Patented in 1870 by Julius Katz of Cincinnati. The patent describes a method of gluing strips of "bone, ivory, or similar hard organic substance" together to make the sole, but the sole of this example is made of two pieces of lignum vitae with the rear piece dovetailed to the body and the front sliding to adjust the throat. 6-1/4" long and identical to the one shown in PTAMPIA II, Figure 162 - we think it's the same plane but can't prove it.

The invention is a modular shipping container, and this patent marks the advent of container shipping which has revolutionized not just shipping but manufacturing worldwide, and incidentally made the inventor very wealthy. McLean's idea was to use containers to facilitate the movement of bulk cargo. Existing bulk-cargo shipping relied on ships that were specialized for one type of bulk cargo, which led to ships being only useful in one-half of a round trip. Thus, the gain in efficiency of more flexible cargo hauling easily offsets the additional expense and inefficiencies of using container ships rather than bulk cargo ships.
