JOHN W. ANDERSON, OF LANCASTER, PENNSYLVANIA.

DEVICE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 252,831, dated January 24, 1882. Application filed August 17, 1881. (No model.)

To all whom it may concern Be it known that I, JOHN W. ANDERSON, of Lancaster, county of Lancaster, and State of Pennsylvania, haveinvented a new and useful Device for Converting Motion, of which the following is aspecification.

My invention relates to that class ofmechanical movements in which oscillatory motion is converted into rotary motion. Its main features are a double-acting'lever or handle pivoted to an oscillatory frame or are, which latter has attached to its periphery two tackle-belts, by which it communicates its motion to a pulley on the shaft of a fan-blower or other machine driven thereby, the said lever serving to tighten and slacken the said belts alternately as it is vibrated to swing the oscillatory frame, thus operating to propel continuously forward the driven parts of the machine. I attainsa-id operations by appliances substantially as illustrated in the accompanying plates of drawings, of which- On Plate 1, Figure l is a side elevation of Fig. 2 is an edge view of the same. Figs. 3, 4, and 5 are views respectively of the oscillatory frame, a take-up key or belt-fastener, and the actuating-lever. 0n Plate 2 are modifications of the same, as follows: Fig. 1 is a side elevation of my device modified at the attachments of the belts, and having the os cillatory frame vertically bisected. Fig. 2 is an edge view of said frame and the actuating-lever inserted between its sections. Figs. 3, 4, and 5 are details of the same.

Similar letters refer to similar parts in both plates.

Referring to the drawings, the main description will be based on Plate 1, and the modifications or Plate 2 will be noticed thereafter.

B T N represent a stand on which my actuating mechanism is mounted for illustration, the same being replaceable by the casing of a fan-blower or other machine.

S represents the driven shaft.

L W is the oscillatory frame, which is pivoted at B to the upright B F F are flanges on its periphery. E is a take-up key, by which the tackle-belts m and a are attached to said frame. The shank of said key is slotted at S to admit in it the end of the belt, and a springstop, L, holds said key, as shown, by teeth on the disk E. The belt m is shown as lined or re-enforced with athin metallic strip, 19, on its back. This is done to stand the strain at heavy work, when the leather belt is liable to stretch. The belt a may likewise be re-enforced by riveting or wiring a metal strip on its back. The flanges F F are designed to keep the saidbe-lts in place on the frame W L, but it is evident they may be dispensed with on close-coupled parts. In lieu of the keys E E and stops L it is also evident any other adjustable fasteners may be used.

The actuating-leverP is pivoted at N to the projection M ofthe oscillatory part L W. Said lever is provided with bits df, to which the ends of the tackle-belts are attached. The operations of saidleveraretwotold first-,ittightem and slackens the belts m nalternately when it is vibrated; second, itswings the are or frame L W about its pivot B, and thus runs the belts on and off the pulley R or its equivalent, afl'ywheel, H being shown on said pulley or hub. Said lever is offset laterally between the bits thereon, that the belts shall be operated thereby free of each other-that is, to prevent their interference with each other. The modifications shown in Plate 2 are actually the same as those parts shown in Plate 1. The oscillatory frame L W is vertically divided parallel to its face. or has an added section, L W, of nearly similar form, applied to its face. Each section has a flange, F or F, and the lever P, pivoted at N on projection M,is inserted in a recess, K, between said sections. Said lever is slotted at D, and a fixed pin, D, on section L W traverses said slot when the lever. is vibrated. On the rim of the sections L WV L W are projections Q Q and studs or arms 0 O transversely arranged, to which the belts m n are attached offset from each other-that is, across the parting-line of said seetionsthat they may not interfere with each other. The rims of said sec ions are cut away at V V to allow the arms 0 O to approach toward and to recede from each other as the sections L W L WV are rocked when the leverP is vibrated. The operations of the actuating-lever are the same as described in the foregoing caseviz., first, it tightens and slackens the belts m n alternately by rocking or oscillating said sections L W L W in opposite directions, the pin D traversingtheslotD as the lever is vibrated; second, it swings the combined sections of the oscillatory frame W W L and lever P about its pivot B as a center of motion, thus sawing the belts m n on the pulley R to communicate their motion to it, as before recited.

The first specified method of construction is preferred where heavy pulling is required at the actuating-lever, and the latter method is preferred for light running machinery. In both cases the engagement is both ways. The crossed belt is the driver at the downstrokcand the direct belt acts at the return-stroke of thelever. Thereforetheiutermittanceot'movement of the actuating appliance does not intermit the rotary motion of the driven pulley or shaft; but it is found the rotary motion wi l be more uniform if the driven partis coupled ith a fly-wheel or its equivalent, which sustains the speed at the intervals when the actuating-lever is being reversed.

In describing my device I adverted to fanblowers as machinery to which my improvement is applicable. I however do not confine my invention to such, as it may be employed to run circular saws, churns, drills, &c.

What I claim is- 1. The applianceforconverting reciproeatory rotary motion into rotary motion, consisting of a double-acting actuatinglever, a vibrating frame or are having on its peripheral extension the fulcrum for said lever, and tackle-belts connected and arranged to communicate the motion of said are or frame to the driven pulley of a machine by alternate engagement of said belts, substantially as and for the purposes set forth.

2. The oscillatory are or frame L W, provided with belts m n attached thereto at E S, and to bits dfon lever P, which latter is pivoted at N to said frame, and operating substantially as and for the purpose set forth.

3. The sections L W L WV of the divided o3- cillatory are or frame, pivoted upon each other at Ben the upright B, and provided with the peripheral extensions 0 Q 0 Q, in combination with belts m n and lover P D applied thereto, all arranged and operating substantially as set forth.

4. A tackle -bclt, m, in combination with sheet-metal lining or rc-enforcementp rivet-ed or wired thereto, substantially as and for the purpose set forth.

5. The oscillatorymotion device composed of the vibratory are L \V, vibratory lever P, belts m n, in combination with a rotary machine having a fixed pulley, It, and a fly-wheel, H,

or its equivalent, all operating conjointly, substantially as set forth.

In testimony that I claim the foregoing as my invention 1 have hereunto set my hand and seal this 13th day of August, 1881.

JOHN W. ANDERSON.
