COMPOUND CRANK.
SPECIFICATION forming part of Letters Patent No. 235,026, dated November 30, 1880. Application filed May 10, 1880. (ModeL) To all whom it may concern:
Be it known. that 1, JAMES S. SCHOONOVER, of Titusville, in the county of Crawford and State of Pennsylvania, have invented a new and Improved Compound Crank, of which the following is a specification.
The object of this invention is to provide a novel device whereby a series of connected machines or mechanisms may be given alternate and successive motion.
The invention consists of a series of cranks or eccentrics united by a central shaft and disposed at equal distances apartabout the shaft, so as to form a complete spiral; and the device is especially adapted for impartingmotion to series of stamps for crushing ores, &c., and more especially for pumps where a steady equal pressure is required.
Figure 1 is a longitudinal elevation of the device. Fig. 2 is a cross-section on line as m, Fig. 1.
Similar letters of reference indicate corresponding parts.
In the drawings, A represents the shaft.
B B are the cranks or eccentrics, that are set so as to form a complete spiral about the said shaft from one end to the other thereof. In this instance eight cranks or eccentrics, B B, are shown as composing the spiral, each succeeding one set an eighth of a circle, or forty-five degrees, in advance of the other; but the number of them may be increased within the circle without departing from the principle of my invention.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A compound crank constructed substantially as herein shown and described, consisting of several cranks or eccentrics arranged spirally at equal distances apart upon a central shaft, so as to form a complete spiral, as set forth.
JAMES S. SGHOONOVER.
