navnnsrne M CHA ISM,

To all whom it may concern:

Be it known that I, Go'r'rmn BINDER, of

Rochester, inthe county of Monroe and State of New York, have invented'certain new and useful Improvements in Reversing Mechanism; andI do hereby declare the following to be a full, clear, and exact descrip imerals marked thereon.

tion of-the same, reference being had to the accompanying drawings, form ng a part of this specification, and to the reference nu- The present invention relates to a mechanism'for reversingJthe movement of ma chineryand is particularly-adapted! use in connection machines such as wash ing machines which embody a member or part arran ed forinovement first inogre di-t" rection, an then in theo posite'di'rection,

"thepresent arrangement o parts being such that the reversing mechan sm is actuatedby the driven member, and is contmually operated in one'direction, while the operating member moves alternately in opposite' direoa 1 pointed out the claims at the =end of the l tions.

To these'and other ends the invention consists in -certam' improvements and combinations-of parts all as will be hereinafter more fully described, the novel features being specification.-

In the drawings: Figure 1 is a view in elevation, illustrating-one embodiment of my invention as applied to a washing machine embodying a member moving alternately in opposite directions; Fig. 2 is' a the-several figures indicate the same parts.

invention as disclosed in the present embodiment, is illustrated in connection with a washing machine of a common type, comprising a frame or casing 1 and shaft 2 which is (:ClllltttiQti to a movable part the direction of whose movement 18 reversed at regular intervals. Mounted on the shaft 2 1 is the gear wheel connected to the motor 4- by a train of gears, or otherwise. The

movement of the operating device 4, which is preferably an electric motor, is governed by a controlling device, wh'iohconsists, in

the present embodimenh of azrotary switch 5, arranged .for cooperation with suitable contacts, so'that the inotor is reversed at predetermined intervals, and the member or part of the machine is driven first: in one direction and then in the opposite direction.

In machines of this general type, it isde- --sirable' to have means'for rotating the controlling switch continually which shall be of simple construction andof ready operation,. and to this end, I'connect the alternately ireversible,or.psc1llatory member or part such as'the shafti of the machine to the control} hng devicefoi switch, iri such a manner that the latter constantly-actuated in one dlICr, tion by the-member orjpart ofthe machine,

switch, thepresent embodiment, is inthe form of a drum, 'vv'hic'zh isimounted on the the directionof rnovement ofwhich is alter nately reversed.- The controlling device, or

pinion 7, and agear' 8 is, suitabl mounted ,for e'n'ga ment with-the inion the gear Spreiera lyibein Ipivo tothe standard '9 which isarrange on the'base 10. Secured to onersrde of; the gear 8 is a ratchet wheel 11, which maybe integral with the gear whee1,or separate therefrom and mounted in any suitable manner. Arranged for engage,- ment-with theteeth of the ratchet ivheel 11 is a awl at'on'e end of the. conneetingrod 12, t e o posite end of which is pivoted eccentrical y of the shaft 2 as indicated at 13. It is to be noted that no matter in which direction the shaft 2 may be rotating, the gear 8 will'be moved in one direction and at each revolution of the memberor part of the machine, as the pawl on theconnecting rod .12 engages, successively, with the teeth of the ratdhet wheel 11. The ratchet teeth in .the present embodiment are so arranged that the gear 8 makes one-fourth of a revolution to every three revolutions of the shaft 2, and the teeth on gear 8 and pinion 7 are so proportioned'that the latter makes two While the 'former is making one revolution, 50- that the reversing switch completes a half turn for each one fourth of a revolution of the gear '8. In other words, at the completion of every three revolutions of-the member or' part of the machine in one direction, the controlling device, or switch, has been. advanced toa point where it-m'oves from'one set of contacts breaking the circuit and completes a circuit throng another set loo oi contacts, reversing the motor, and liketacting positions.

wise the movement of the shaft 2.

By the construction thus far described, the movement 'of the conducting points of the switch -from one set of contacts to another is so slow t-hat it might cause serious arcing or a stoppage of the machine, which is, of course, undesir'ableIand I have devised a'means for effecting aquick movement of the switch between *successivecon- The speed increasing means, in the present embodiment, operates on a double cam .14 which is fixed to one end of the shaft 6 and is provided with beveled portions 15 for a purpose which will presently be made clear.

ably. in a yoke formed on the lever, The roller 19 is held in constant engagement with the cam by means-of, a spring 20 positioned between the top of the standard 16 and the lever 18, and provided with means for adjusting the tension thereof. The camsl i ;is so arranged that the roller 19, ridin war'dly on the same, reaches the highest point immediately prior 'to the breaking of the circuit by the switch, and just as the aircuit is broken, the riiller'j engages the beveled surface 15 and is forced downwardly by'the action of the spring 20, causing the shaftfi to be quickly turned a distance correspond: ing to thecircumferential distance between the limits'of the beveled surface 15,- thus causinga sufiiciently'quick movement-pf the switchbetween successive contacting positions. In this manner, reversal of the motor is quickly obtained at the propertime and any serious arcing between thecontacts of the switch or possible stoppage of the machine is obviated. v A

In order to preventtoo sudden lowering of the lever. 18' or an overthrow of the ratchet wheel, there is provided a dash 0t 21 of any suitable construction, the same eing connected to the lever 18 atthe free end of the latter by the link 22.

By the construction and arrangement described, there is' afforded a mechanism of very simple construction, and extremely efficient in its operation for efle'cting a pro-. gressive movement of acontrolling device ,by an alternately reversing member or part whichis operated by a motor, the reversing of which is-accomplished by thecontrolling device, and it will be understood that the invention is susceptible of use in any machine'embodying a movable art which is actuated alternately in opposite directions.
