Manufactured by Helm Tool Co. - Chicago IL

" This invention relates to a universal joint, and more particularly to such joints that can be made in groups having a plurality of units for increasing or varying the angle between the axis of the driving element and the axis of the driven element. The present invention is an improvement over that disclosed in the patent to Helm & Derleg No. 2,760,358, granted August 28, 1956. In the use of mechanic's tools, it often occurs that a considerable angle exists between the axis of the driven element and the available position for the axis of the driving element. By the use of the present invention I have made it possible to transmit such driving force through angles greater and less than three hundred and sixty degrees. " The patent number appearing on a known example marked "THOR" reflects manufacture for distribution by Independent Pneumatic Tool Co. (Aurora, IL). Also distributed by Snap-On. An extensive "GARAGE JOURNAL" discussion about the tool provides context and additional details.

Abstract: The double hydrostatic oil press as constructed by us operates upon the seed, or other substance to be pressed, by means of two pistons which are forced out of the opposite ends of a cylinder placed horizontally, which two pistons are subjected simultaneously to the power produced by the ordinary hydrostatic press, or any forcing pump operating upon the same principle. Claim: The employment of two pistons operated upon in the manner, and for the purposes herein set forth for pressing oil from seeds, and for pressing other articles to which the same may be adapted by means of hydrostatic pressure, by which means the labor of so doing is lessened, not because any increase of power is obtained, but because two charges are pressed at the same time, and the charging with water, and also the discharging has to be less frequently performed.
