MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 758,914, dated May 3, 1904.

Application filed June 26, 1903. Serial No, 163,180. (No model.)

To all 207mm it may concern:

Be it known that I, WVILLIAM HANSON, a citizen of the United States, residing at (Jalistoga, in the county of Napa and State of California, have invented new and useful Improvements in Mechanical Movements, of which the following is a specification.

My invention has for its object to produce a mechanical movement or driving power for operating light machinery and performing other work where a steady and evenly-running motion is desired; and the invention comprises certain novel construction and combination of parts and mechanism, as hereinafter described and afterward pointed out in the claim at the end of this specification.

The construction and operation of my improved mechanism will be understood more clearly by referring to the accompanying drawings, in which- Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is an enlarged view in elevation of the central rocking lever, parts of the lever beingbroken away and its central portion being in section to illustrate its support on the main shaft. Fig. 3 is a top plan view of the mechanism shown in Fig. 1. Fig. 4: is a view, partly in plan and partly in horizontal section, of the parts supported upon one of the shafts s.

The principal parts of this machine comprise a main driving-shaft a, two windingdrums b, carrying cords c with heavy weights (1 (l on their ends, and means connecting each drum with an oscillating lever e, through the movements of which the drums are turned in the proper direction to wind up the weights. The drums b are connected with the belt-carrying pulleysff in a manner to be described, and these in turn are connected by the belts g g, the pulleys v o, and other connectinggearing, to be later described, with the main shaft (1, so that the power from both descending weights (Z operates to turn the main shaft.

The means for winding up the weights con sist of rocking levers e e, mounted loosely on the shafts s .s and carrying pawls 2', arranged to engage with the ratchet-wheels is, secured to the shafts .s The levers e are connected by rods or links 2? with an oscillating lever it, that is mounted so as to turn freely upon the shaft a. The ratchet-wheels k and the drums b, from which the weights are suspended, are secured fast to their respective shafts a, while the pulleys ff are loosely mounted thereupon, but have connection with their shafts and through it with the drums by means of ratchet-wheels p, secured to the shaft, and pawls 91, carried by the pulleys. It will be seen that if the lever it be oscillated it will operate to rock the levers c e and they in turn through the pawls i, which they carry, and the ratchet-wheels Z7, engaged thereby, will operate to turn the shafts a and the drums b in directions to wind up the weights (Z. W'hen this is being done, the pulleys ff" will remain stationary. On the other hand, when the weights operate to turn their shafts motion will be communicated from the latter through the ratchet-wheels p and the pawls to the pulleys ff. A belt g connects the pulley f with a pulley 0 on the main shaft a, while the pulley f is connected by a belt g with a pulley a, fast on a short shaft 3 that is connected with the shaft (0 by spur-gearing 2 3. This manner of connecting the second beltpulley instead of placing it directly on the shaft a is done to reverse the motion of that pulley and apply it to the shaft a in the proper manner to act in harmony with the other pulley, and thus cause both pulleys to act on the shaft (4 in the same direction.

Power is applied to the lever it to rock it on its center by connecting with the shaft n by means of a crank and a connecting-rod 5, having one end attached to the lever 7: at a point below its fulcrum and connected at the opposite end to the crank-pin l. The latter is fixed in a disk 6, fast on the end of the shaft, and a hand-crank 7 is provided in the end shaft for turning it. As thus constructed and arranged the descending weights act through the drums, pulleys, and belts to rotate the shaft a in the same direction, while the movements of the oscillating lever h, acting through the rocking levers .s' and their pawl-and-ratchet wheel connections, turn the shafts in the proper direction to wind the cords on the drums.

rocking lever with the shaft upon which it is supported; means connecting the oscillating lever with both rocking levers; a driven shaft, and pulleys and belts connecting the two drumshafts with the last-named shaft to rotate it in the same" direction.

In testimony whereof I have signed my name in the presence of two subscribing witnesses.
