REVE RSING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 465,920, dated December 29, 1891.

Application filed May 15,1891. Serial No. 392,933. (No model.)

To all whom it may concern.-

Be it known that we, ROBERT S. CARR and EDWIN J. SCHRODER, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Reversing Mechanism, of which the following is a specification.

This invention relates to improvements in a reversing mechanism of that class driven by belts traveling in opposite directions, being alternately shifted on and 0E a tight drivingpulley; and the objects of the improvements are to provide adjustments that may be regulated to cause the belts to be automatically shifted when the reversed shaft has described any desired number of revolutions, to retain the driving-belt full on the face of the driven pulley until shifted, and to cause the shifting of the belts to be done instantly. These objects are attained by the mechanism illustrated in the accompanying drawings, in which Figure 1 is an end elevation of the mechanism attached to a portion of the end of a washin g-machine Fig. 2, aplan of thesame, showing parts of the washing-machinein section; Fig. 3, portions of lever L and radial arm K latched together and enlarged; Fig. at, a transverse diametrical section of an intermediate ring of the series M enlarged; Fig. 5, an enlarged ele Vation of the inner ring of series M,an d Fig. 6 a transverse diametrical section of Fig. 5. Fig. 7 shows end elevation, with parts in section, of mechanism attached to portion of the end of a washing-machine; Fig. 8, a diametrical section of series of rings and portion of gear-wheel on shaft B; Fig. 9, a vertical section through lug o of the cap of journal-box; Fig. 10, end elevation of ring with cam; Fig. 11, enlarged side view of the mechanism, a portion being in section; Fig. 12, a diametrical section of portion of gear-wheel and of rings on shaft B, the rings being disengaged from each other; Fig. 13, an end elevation of one of the rings of series M.

A represents a portion of a cylindrical washing-machine; B, a shaft to be alternately reversed in its direction of rotation; O, a bracket bolted to said machine and constructed with journal-boxes a and b; D, an angle-plate with trunnion 0, extending through box I), radially adjustable therein; E, a shaft journaled in box a and extending through said trunnion; F, a tight pulley, and G loose pulleys on said raised.

shaft E to gear in and drive'wheel I, fastened on shaft B; and f and g shifters for belts cl and 6, respectively, pivoted to angle-plate D and geared together to shift said belts simultaneously in the same direction by motion imparted to arm j of shifter g by radial arm K through swivel h in the end thereof, in which arm j is transversely inserted against coilspring 2' therein. Arm K is radially oscillated on trunnion c by lever L on hub 70, fastened to said arm in slot Z therein. Said lever carries stop m and has fingers 11 depending beyond shaft B through curves described from hub 70. A series of rings M turn loosely on shaft B extended. The outer ring is fastened by a setscrew and turns with said shaft to consecutively gather or take up and turn the other rings of said series by the contact or engagement of lugs O, that travel in grooves p in the sides of adjoining rings. Collar N on the inner ring bears against the hub of gearwheel I. Flange P on said inner ring supports lever L by lip r. A cam 0r lug R onthe inner side of said inner ring operates between and alternately against the adjacent edges of fin gers n to reciprocate lever L. S represents a spring-latch on the side of said lever, operated by thumb-piece T to engage catch 23, integral with hub 70, to fasten said lever when The weight of said lever, whenfastened, turns arm K until stop m restson the end of thumb-screw u, which is adjustable through lug o, raised on the cap of box I), to stop said arm with the belts on their respect ive loose pulleys G.

In operation lever L is raised to shift belt e on pulley F, then unlatched from catch 2, and lowered to its normal position. Each revolution of shaft B engages a ring of series M.

until cam R on the inner ring moves said lever outwardly by its action on finger n, which motion of lever L is communicated through arm K, swivel h, and arm j to the shifters to shift belt (1 on pulley F and belt 6 on its corresponding loose pulley G instantly and simultaneously. The direction of shaft B is consequently reversed and takes up the rings of series we in its reversed direction until cam R moves lever L back again by its action on the other finger n to shift belt 6 on pulleyF and belt (Z on its loose pulley G, thus automatically shifting belts d and e alternately on and off pulley F and reversing the direction of rotation of shaft B. Cam R remains against finger n to hold lever L until turned against the opposite finger n by the engagement of the rings of series M. Spring '5, acting against the end of arm j, prevents the shifters being moved by the belts. Radial arm K, oscillated by lever L, may be adjusted on hub to the extent of slot Z, and angle-plate D may be correspondingly adjusted in box I) to accommodate the shifters to belts having other than a vertical angle. Annular grooves 19 in the sides of the rings of series M terminate against lugs O, integral with said rings. A set-screw may be inserted in each ring to fasten same to shaft 13 to limit the number of intermediate rings to be engaged and correspondingly reduce the number of revolutions of shaft B until reversed. Any number of rings may be left to engagement by lugs O in series M to regulate the time of reversing shaft B, as desired.

We are aware that prior to our invention reverse mechanisms operated by alternately shifting belts that travel in opposite directions have been made and patented. We therefore do not claim such a combination, broadly; but
