This invention relates to improvements in gearing, and. is a continuation or division of my co-pending application filed May 13th (now patent 4 984,831, dated Feb. 21st 1911) as to the eccentric for actuating the agitator through intermediatemechanism, and as to the specifi'c construction of the eccentric and its cooperating parts.

Referring now to the drawingsFigure 1 is a perspective View of my improved washing machine which embodies the pres,- ent invention. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical sectional view on the line 83 ofFig. 2 the hinged tub cover being shown closed in fulllines and fully open in dotted-lines. Fig. 4 is a vertical sectional view on the line 4% of Fig. 2. Fig. 5 is a detached perspective view of the eccentric, its strap and operating parts, the parts being shown in separated relation. carrying out the present invention,

preferably a horizontally arranged tub l is provided, which is supported upon suitable legs 2. Thewashing and wringing mechanisms are driven, as here shown, by an electric motor 3, of a low horse power, and this motor is supported upon a suitable shelf orbracket 4,-"which is secured to the legs 2,

i ,the motor being located under-the tub and out of the way. While an electric motor is.

shown and described, yet it is to be understood that other forms of motor may be tubl, is hinge-d in a manner to bc hereinafter described. At one edge of the top of the tub a suitable board 6 is attached thereto, and this board supports the driving mechanism which will now be described. 'At one end of the board 6, a .base 7 is rovided and at the opposite end of the card is a base 8. Projecting vertically from the base 8 is an arm 9 which carries a'bearing 10, and projecting from eachend of the base 8 are vertically disposed arms 11,

which carry bearings" 12 -A driving shaft:

.is asuitahle housing 27, in which the upper 18 is journaled in the bearings 10 and 12 and this shaft, as shown, extends across but above one edge of the tub l, and parallel with the inner straight edge of the cover 5. Suitably ournalcd in the outer end of the. base 7, is a suitable combined driving pulley and balance wheel 15, the shaft of which carries pinion 16, which meshes with a gear 17, the gear being rigidly attached to the shaft 13. A suitable belt 18 passes around the. pulley 15 and a small pulley 19 on the shaft of he motor 3.

A vertical shaft 20 is journaled in the cover The inner or lower end of this shaft 20 carries an agitator head 21, to which is attached suitable agitator arms A'vertical socket 23 projects from-the agitator head 21 and the inner end of the shaft 20 is connected to this socket in any suit able way to permit the agitator to move toward .the cover 5 when it, is opened, as shown in Fig. 3, and at thesamc time locked to the socket 23 against independent revolution, whereby the rotation of the shaft 20 causes the agitator 21 to be rotated. As here shown the means consists in having the socket 23 provided with an angular longitudinal opening 24: and. the end of the shaft 20 with a correspondingly slia d head 25. The cover 5 is provided with an opening 26 to permit the upper end of the socket 23 to pass thereinto when the cover is opened, as I shown in dotted lines, Fig. 3.

Attached to the outer s'idc of the cover 5,

end of the shaft 20 is journalcd. Rigidly attached to the upper end of the shaft 20 and within the housing 27, is a gear 28. A. reciprocating gear rack 29 moves in the housing 27 and engages the gear 28: vWhen the gear rack 29 is rcciprocated, the gear 28 and the agitator 21 are alternately rotated in opposite directions, whereby the agitator agitates the clothes within the tuband this effects the washing thereof in the this art.

The means forreciprooating the rack-bar 29 consists of an eccentric 30, around which passes an 'e'ccentric strap 31. the straphavmanner well understood by those skilled in I ing a projecting arm or pitman 32, which I has its outer end loosely connected with the" rack-bar 29 at the point 33.

The eccentric 30 has a flanged bearing 34., which is normally loosaupon the shaft 13 and that end of the sleeve 3% which. is adjacent the bearing 10 is provided a collar 35 which interlocks with a. flange 36, projecting from the bearing 10, whereby the eccentric is held against endwise movement on the shaft 13. The opposite end of the sleeve is adapted to interlock with a clutch 37 that is longitudinally movable on the shaft 13. This clutch and the adjacent end of the sleeve 3% are provided respectively with interlocking means, such, for in stance, as a slot and projection 38. The clutch is permitted to have longitudinal movement on the shaft 13, but is caused to rotate therewith by means of the well-known slot and pin construction 39. it clutch operating lever 4:0 is intermcdiately pivoted upon a bracket 41, the inner end of the lever 40 having the usual well-known yoke construction 12, adapted to interlock with a groove 13 made in one end of the clutch 37. The pivotal bolt &1 passes loosely through an opening in the lever 40, and a suitable spring lli serves to normally hold the handle end of the lever 40 in locked en gagement with either of the notches 4t? upon the bracket 11. By lifting up on the handle end of the lever 10, it can be disengaged from the notches a? for the purpose of cau ing the clutch to either interlock with the sleeve- 3-l or" the eccentric and cause the cocentric to revolve with the shaft 13, or to be disen aged from the sleeve 34 and permit the driving shaft 13 to rotate free within the sleeve and without agitating the cocentric.

The opposite end of the driving shaft 13 from the pulley 15 is adapted to be operatively connected or disconnected from the wringer 43. The mechanism for accomplishmg this comprises a beveled gearwheel 49, which is rigidly attached to the projecting end of the shaft of one of the wringer rolls 50. As here shown, this gear is attached to the lower roll. Located on the shaft 13, at opposite sides of the beveled gear 9 and constantly in mesh therewith are beveled gears 51 and 52. These gears are loose on-the shaft 13 and placed between them is a clutch sleeve 53. This clutch sleeve is longitudinally movable on the shaft 13, but is caused to rotate therewith by the well-known slot and pin construction 54. The opposite ends of the clutch 53 are adapted to either interlock with the beveled gears 51 or 52, or to be held out of locking engagement with either of the gears. This is acconnilished through the medium of an operating lever 55, which is int: yzdiately pivo d at the point 56 in a man. similar to the all), before describe,"w A yoke 57 is formed on the inner end of the lever and is adapted to engage a groove 58 in the clutch sleeve 53 for the purpose of moving the clutch sleeve, and the lever 55 and Locales thereby the clutch sleeve 53 is locked in po-. sition to hold the clutch sleeve in engagement. with either of the beveled gears 51 oror out of engagement with both by engaging the notches 59, the lever 55 being adapted to interlock with either of the notches 59, or be unlocked therefrom in the v 'same time and the wringer rolls caused to rotate in either direction. 1

The object of reversing the direction of rotation of the wringer rolls is to permit the clothes to be wrung from the tub into a bluing or rinsing tu'b located outside of the wringer, the clothes passing over a suitable shelf 60, falling into the rinsing or bluing tub located thereunder, and by reversing the wringer rolls the clothes can be wrung from the bluing or rinsing tub without moving its position, and thus avoiding the necessity of carrying the rinsing or bluing tub with the clothes to the rear of the machine. I

The electric cable 61 has one end connected to the motor 3, and the opposite end provided with a wellknown socket 62 ada ted to be placed in the ordinary electric light socket, and intermediate the socket 62 and the motor a switch 63 is provided for the purpose of having convenient means for turning on and cutting oil the current to the motor.

Referring now to the hinged construction for the cover 5, it comprises a hinge which has its pivotal point located in a plane above the cover and at a point inside of the driving shaftv 13. This is accomplished by providing the cover hinged plates 64 with upwardly' projecting arms 65 and the inwardly projecting arms 66, which project respec tively from the arms 9 and 11 of the bases 7 and 8. The outer ends of the arms 65 and 66 are hinged or pivoted together at the point 67,

is above and extends outwardly over the driving shaft and its operating mechanism as shown in dotted lines, F'g. 3, which permits access to the tub 1, without and interterence by the agitator, and also raises the cover and the agitator in such position as to leave free access to the wringer. When the cover 5 is in thisraised position, the'z agitator will drop down on the shaft 20, which also serves to carry the agitator out of the way of the operator to some extent. The use of the eccentric 3O accomplishes a smooth action of the mechanism for operating the agitator By reason of this elevated hinged construction the cover 5 when open Locales v and prevents any knocking or jerking action in the reversing movement caused in the agitator, and is also found to reduce the power required to drive the agitator, thus enabling asmaller and lower powered motor to be used which is economical in operation,

and in the first cost,

By reference to Fig. 5, which shows the specific construction of the eccentric, it will i the wringer, whereby the driving shaft 13" is common to and-adapted to drive both the' washing and the wringing mechanisms in the manner heretofore described,
