Letters .Patent N 96,746, dated November 9, 1869;

IMPROVEMENT IN MECHANICAL MOVEMENTS.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom it 'may concern..-

The. nature of my invention consists in lthe con-- struction and arrangement of certain devices, by which an oscillating motion is converted into a rotary motion, and also in the manner of rotating a spindle or shaft,

, in either direction, by applying a single or double Spring.

In order to enable others skilled in the art to which my invention appertains, to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which#- 5' f lFigure l is an end View, and Figure 2, a plan view of my invention.

.i Figure 3 is a side view of the oscillating lever, with the springs attached.

Figure 4 is a side view of the spindle or shaft and Figure 5 is a perspective view of the connectingpiece between the oscillating lever and the spindle or shaft to which it is desired to contribute a rotary motion.

A represents the rod or lever, which, by any inachinery or device, has an oscillating motion.

Its inner end is slightly bevelled outward', from the centre to the upper and lower edges, as seen in tig. 3, forming a depression across the centre.

This end of the lever A is also slotted, and in this slot is pivoted a tlnee-cornered block, a, from the base of which project two curved springs, b b, one above and one below the bevcllcd end of the lever.

,lhe outer angle or corner of the block a is slightly raised upward, or pressed downward, by means of a pi n, e, which is inserted either below or above said block, through the lever A, as seen in 2 and 3.

Illhe bevelled end of the lever A is inserted into a recess, (l, in au elliptical-shaped block or cylinder, D, and pivoted in the same, said recess opening into a round hole, f, through the. block, running at right angles with the lever A.

'Ihe edges of the bevelled end of the lever A project slightly within the hole f, when the lever is either raised or lowered, but when hchl in a certain position, the edges should be even with the sides of the hole j'.

The springs b b, when the lever A is pivoted in the recess d, bear on the outside of the cylinder, one above and the other below the same.

Through thellole f, in the cylinder D, is placed a spindle or shaft, B, which, at the point where the recess d opens int-o the hole f, is not round, but polygs ouai-shaped, as shown in iig. 4.

It will readily be seen, that when the pin c is inserted, either above or below the block a, the lever A, by the action of the springs?) b, on the outside of the cylinder D, becomes rigidly fixed in said cylinder, in such ainanner that one of the edges will project from the recess d, and bear against the sides of the shaft B, and consequently, when the lever A is in motion,4 that is, has its oscillating motion, it will turn the shaft during, for instance, its upward motion, but slip over the salue during its downward motion, and thus cause the shaft to turn steady in one direction.

The direction in which the shaft B turns is easily changed, by moving the pin c to the other side of the block a, as thatat once changes the position of the edges o f the lever within the recess a, the springs b bV at alPtimes holding the lever rigid enough to turn the shaft, but still yielding a tritie at the tirst shock.

By these means, lthe oscillating motion is converted into rotary motion, and the direction of the rotary motion is changed by the springs holding the oscillating level' in the required position.

Having thus fully described my invention,

That I claim as new, and desire to secure by Letters Patent, is-

1. ,'Ihe oscillating lever A, cons'cructod as described, with bevellcd end, and a slot through the saine, suhstantially as and for the purposes herein set forth.

2. Ihc tln'ee-cornered block a, provided with springs l) b, substantially as and for the purposes herein set forth.

3. The combination of the lever A, block a., springs I) b, pin e, and cylinder l), all constructed as described, and for the purposes sot forth.

4. The combination and arrangement of the oscillating lever A, with the blocka, springs b l), and pin e, the cylinder D, and shaft B, all constructed as dcscribed, and operating substantially in thc inanucr and for the purposes herein set forth.

1n testimony that I claim the lin'cgoing, as my own, I atlix my signature, in presence of two 'witnesses.
