MECHANICAL MOVEMENT.
No. s40, 58 1.
Specification of Letters Patent. Application filed June 24,1905- Serial No. 266,816.
Patented Jan. 8, 1907.
To all whom it may concern.-
Be it known that I, DAVID NELsoN, a citizen of the United States, residing at Burma, in the county of Sebastian and State of Ar- 5 kansas, have invented a new and useful Imf provement in Mechanical Motions, of which I the following is a specification.
This invention relates to a mechanical mo tion in which the reciprocation of a leverby hand or by a pitman or crank-rod or the partial rotary movement of a rock-shaft when rocked is transformed into continuous rotary movement in one direction.
Theinvention consists in the novel fea- I tures of construction and combination .of parts hereinafter described, pointed out in the claim, and shown in the accompanying drawings, in which Figure 1 is a side elevation. plan view. Fig. 3 is a section on of Fig. 2.
In the drawings, A represents a frame in which are journaled parallel shafts B, O, D, and E. On the shaft B are fixed gearwheels B and B On the shaft O are loosely mounted gear-wheels O and C The gears B and O are intermeshing. The gears B and C do not directly mesh, but are entrained, meshing each with a pinion D on the shaft D. On the shaft E are slidably keyed pinions E, adapted to be brought into mesh, respectively, with the gear-wheels O and C Adjacent each of these last-mentioned gear- Wheels, which, it will be remembered, are loose on the shaft O, a ratchet F is fixed on l the shaft O, and each gear-wheel O and C Fig. 2 is a the line 3 3 carries a awl J, adapted to engage its adjacent ratcfiet F, the said pawls and ratchets being oppositely disposed and held in engagement wlth their ratchets by a spring J. i The construction being described, the opl eration will be obvious. I have shown a handle G to rock the shaft C; but the handle p or lever G may consist of a crank ivotally connected to an engine-pitman, as t e device may employ hand-power, being driven from an engine or from a motor, as may be most convenient. The rocking of the shaft O will impart alternate the wheels O and O and a continuous rotary motion in one direction to the gear-wheels B and B and consequently to the shaft B. The rotation of the shaft B can be employed'in driving machinery in any suitable manner. When it is desired to have the machine driven readily reversible, the pinions E are brought into play, the machine being driven in any desired manner from the shaft E. By sliding the pinions E and bringing first one and then the other into engagement with the gear-wheels C E is reversed, and in case the gear-wheels C and O are of the same diameter but one pinion E will be required.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
A device of the kind described comprising a shaft, means for rocking the shaft, gearwheels loose on the shaft, a fixed ratchet adj acent each gear-wheel, a springressed awl carried by each of the gear-whee s and a apted to engage the adjacent ratchets, said pawls being oppositely disposed, a parallel shaft, gear-wheels fixed thereon, one of said gearwheels meshing with one of the loose gearwheels, an intermediate shaft, a pinion thereon, said loose an fixed gear-wheels, respectively, a third shaft, and a slidable gear thereon adapted to mesh with said loose gears, as and for the purpose mentioned.
