MECHANICAL MovEM ENT.

SPECIFICATION forming part of Letters". Patent No. 235,432, dated December 14, 1880.

Applicationled June 2, 1880. (No model.)

To all whom it may concern.-

Be it known that I, HENRY HASSENPELUG,

` mechanical movement. Fig. 2 is a partial side view of the same, showing'the parts in a different position. Fig. 3 is a cross-section of same.

This invention relates to a new mechanical movement useful forv propelling vehicles, driving machinery, and the like 5 and it consists of a new combination-of parts for converting the rotary motion of a drivingfshaft into oscillating motion of an elbow-lever, which oscillating motion is again converted into rotary motion of the driven shaft, the entire mechanism being .readily reversible.

In the drawings, A is the driving-shaft, and B the shaft to be driven, both said shafts being hung in a suitable framework, C.

The shaft A carries a suitable crank-handle, b, for turning it, said crank-handle being preferably slotted, to be adjustable as to length and power.l The shaft A carries also' a toothed wheel, a, which is eccentric on the shaft, as shown, andwhich is between two toothed racks, c and d, formed above and below it on an elbowlever, D, that is hung to the frame O at c.

`The distance between the racks @and d equals the double length of the larger radius of the eccentric-pinion a and exceeds the diameter of said pinion, so that upon being revolved the pinion will rst gear into the rack c and then into the rack'd, and so on, and never into both racks at once. By thus alternately gearing into theracks c d the pinion will carry the one rack to the right and the other to the left, and thereby oscillate the lever D.

An arm, f, of the lever'l) connects by a rod, g, with a crank, h, of the shaft B, by which connection the oscillating motion of the lever D is converted into rotary motion of the shaft B. The motion of the shaft B will be reversed without reversing the motion of the shaft A, according as the crank h stands to the right or left of the shaft B when the operation of turning the shaft A commences. Thus, in the position shown in 1Eig. l, if the shaft Ais turned in the direction of the arrow 1, the lever D will first be moved in the direction of the arrow 2 and the shaft B turned in the direction of arrow 3,V the rod g being first raised, and in this motion the shaft B will continue until arrested; but if at the commencement of operation the crank h and rod g were as in dotted lines in Fig. 1, the motion of shaft B would be reversed without reversing that of shaft A.

Great power and certainty of action are obtained by this mechanism.

I claim- 1. The combination of the shaftAand eccentric-pinion a with the pivoted lever D, having racks c and d, the distance between which eX- ceeds the diameter of the eccentric-pinion, substantially as herein shown and described.

2. The combination of the shaft A, eccentricpinion a, lever d, and its racks c and d with the rod g and crank-shaft B, substantially as herein shown and described.
