Manufactured by Best Manufacturing Co. - San Leandro, Alameda County CA

Abstract: It is the object of my invention to provide an elastic support for the boiler, engine, and supporting-frame of a traction-engine, and such connection between the frame and the bearing-wheels and axle thereof that the movement of the supported parts upon the springs will not interfere with the proper meshing of the gears by which power is transmitted from the engine to the gears upon the main bearing-wheel whereby the latter are revolved. Claim: The combination in a traction-engine of the frame; the bearing-wheels; the axle; transverse plates forming a channel within which the axle is movable; yokes suspended directly from the axle, and plates through which the ends of the yoke pass; and springs disposed between the last-named plates; said first-named plates bearing directly upon the uppermost of the last-named plates.

The adjusting worm of an adjustable open end wrench has slots into which a spring-tensioned "U" shaped latch can enter, forming an adjustment lock. An analogous form employing a ribbed spring for notches in the adjusting nuts of "monkey wrench" and "Stillson" type pipe wrenches appears in parallel patent 1,367,407.

Manufactured by Lane Co., Inc. - Altavista VA
Assigned to Lane Co., Inc. - Altavista VA

This distinctive table top with its very large dovetail patterns at either end was made as a coffee table in Lane's "Acclaim" furniture line. We have also seen the patent number on an Acclaim dining table and on a pair of Acclaim nesting tables, though the dovetail motif appears only on the upper, larger table.

Improvements to the manufacture of sale by the evaporation of brine, and specifically to what is known as the Alberger process of making salt. The Alberger process involves a circulating volume of brine that is heated at certain points of the loop and then permitted to evaporate at other points, as described in this inventor's patent 1,141,999. The improvements involve the use of pressure to raise the boiling point of brine, filters to remove gypsum and other impurities (gypsum precipitating out at 135 degrees Celsius which is above the boiling point of brine at standard pressure). After the filtering step the pressure is dropped so the brine flash-boils. The remaining brine the goes to an evaporating pan until it returns to room temperature, by which time much of the salt has precipitated out. The remaining brine is then mixed with fresh brine and brought to the start of the cycle. The resulting salt is flaky and variations in this process allow the range of grain size to be controlled which is an advantage as the mix of grain sizes desired tends to vary with the seasons. This process is expensive compared to processes that produce the more common cubic-crystal salt but for some applications it is highly desirable. The Port Huron / St. Clair area was, and remains, a center of salt production due to the region's 400-million-year-old salt deposits a couple of thousand feet underground. Based in St. Clair, Michigan, Cargill Salt Co. is the world's only remaining producer of Alberger process salt.
