Application -fi1ed:Decen1ber 23, Serial I To all whom it may concern:

provement in Washing-Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates generally to motordriven Washing machines of .the'type employing a vertically reciprocating plunger carrying on itsflower end-a pounder or clothes engaging. member and my invention relating more particularly to :a clutch mechanism which is interposed between the motor-driven shaft of themachine and the reciprocating plunger-and said clutch vbeing specifically designed for throwing the .reciprocatingshaft or plunger into or out of operation and which clutch; when discon nected, beingarranged so :as to stop the reciprocating-shaft or plunger at the termination of its upward stroke rmovement.

A. My improved clutch mechanism is particularly applicable for that type of washing machine which includes a container, a

hinged cover therefor, a :[rod or plunger of-said plunger. this particular. type of machine, the relative sizes of the container andthe pounder or clothes engaging mem her are such that the hinged cover for-the container can be swung into full open position only when the plunger is at its highest point of movement within the container, for ifanlattempt .is made to swing the hinged cover into open position with the pounder its lowered position, the edge of said pounder will strike againstthejside wall of the container, with the resultthat the parts are bentor broken. To overcome this ob- Qjection, I propose to provide a clutch mechanism which will be efiective in stopping the reciprocating rod which carries thepounder at the end ofits upward movement and in which positionthe cover'can be read- Qilyswung intoopen position without contact between :the pounder andcontainer.

Fixed in any sultable manner on ranged shaft, 12 is a st'andor bracket-l7, the upperendthereof being provided with {rod 1 which is arranged ior reciprocatory movement throughthe centralportion of the cover 11, -13 the i-pounder or clothes engag- V ing member carried by-V-the lowerlend of said rod 12, 14a fiy wheel, 15 a ,pitman arranged thei cover 11 to onejside of the centrally ,ar v

The ad acent or inner ends of the shafts 20 and 21 are connected and maintained in alinement by an axially -,disposed p n or stud 22, the same being fixed to either one of the shafts 20 and 21, and looselyseated in the other.

Fixed on shaft 20 adjacent to'bearing 18 is a collar 23 and mounted for sliding movementupon shaft20 adjacent to this collar is a second collar 24;. This collar 24 is held to rotate with shaft 20 by means of a pin 25 which passes through said shaft and formed in said sleeve is an annular groove 31. The inner end of this sleeve 30 is provided with a clutch face 32 which includes a recess 33, the latter being adapted-to receive lug 29. The opposite end of sleeve 30 is provided with a notch or recess 3 1 which is adapted to receive a pin 35, the latter projecting inwardly from bearing 19.

Fixed to the bearings 18 and 19 and serving as a cover for thelclutch mechanism just described is an inverted U-shaped plate 36 on top of which to one sideof the center is I fulcrumed a short hand'lever 37. Formed through the cover plate and concentricwith the axis of the hand lever is an arcuate slot 38, and seated in the hand lever and proj ecting through this slot is a pin 39, the lower end of which carries a roller 40 and thelat- :tQPOCCIlpYlIlg groove 31 in sleeve V 30.

is a spring-pressed pin 41, the lower end of pair of recesses 42, the latter being formed 'inthe top of cover plate 36. (See Figs. 2

andfi) This spring-pressed pin is effective yieldingly retaining the hand lever in i'either one of its set positions, and which positions determine the engagement or disengagement of the clutch;

The relative positions of the pitman 15,

pin 35 and notch 34: are such that when the rod 12 will be held at itsupper limit of movement or in the position illustrated in .Figs. 1 and Under such conditions, it s will be understood that the clutch is disengaged and to effect such disengagement, the hand lever37 is shifted to its'limit of movement toward the righthand, as seen in Fig. i

. f sition. Seated in the underside of hand lever 37 2, and such movement is transmitted to said thereof in order-to transmit rotary motion from the main driving shaft 16 to shaft 20 and thence to shaft 21which carries fly wheel l'to which pitman 15 isconnected, thehand lever 37 is moved to its lefthand limit of movement, which 7 action shifts sleeve 30 toward the lcfthand, and by so doing, brings clutch face 32 into coiiperation with clutch face 28 andwhen collar 2 1 rotates to the proper position, lug 29 will lengage in notch or recess 33, thus locking the two parts of the clutch together with the result that the rotary motion of shaft '20 will be transmitted to shaft 21 andf-parts car'- ried thereby. r

It, will be readily understood'that minor changes in the size, form and construction of the various parts of my improved device may be made and substituted for those'herein, shown and described, without departing move lengthwise uponsaid shafts, a lever provided with locking pins for shifting one of said clutch members lengthwise" upon its shaft and locking sald member in position,
