To all when it may concern Be it known that I, ALBERT. L. SESSIONS, a citizen of the United States, and a resident of Bristol, in the county of State of Connecticut, have invented a new and {Improved Washing-Machine, of which the following is a specification.

Miyinvention relates to the class of devices employed clothes, fabrics and the like by mechanical means, and the "object of my invention, among others, is to provide a device of this class that may be readily attached to and detached from tubs or like devices of ordinary construction and that shall be simple in construction and effective in operation.

One form of device embodying my invention and in the use of which the objects aboveset out, as well as others, may be attained is illustrated in the accompanying drawings, in whioh- Figure 1 is a plan view of a portion of a tub showing" my improved washing appa- ,ratus attached thereto, the driving shaft being broken ofi. I Fig. 2 is a view in vertical section through the "device on a plane passing centrally through the agitating hood. Fig. 3 is a detail top view of the lower bracket. Fig. 4 is a view in' elevation of the top bracket; Fig. 5 shows in detail the brackets for supporting one end of the shaft. Fig. 6 is a detail view in elevation of a modified form of agitating hood.

- Fig. 7 isa bottom view of the same.

In'fthe accompanying drawings the numeral'6 denotes a tub of ordinary construction that may be supported upon standards 7, in'the device herein shown there being twoof these tubs separated by the usual wall or partition 8.

In carrying out my invention 1 provide brackets which may be removably attached to the tub, one coiiperating with'the otherto hold it in place, and these brackets having bearings and like supports for diiferent parts of the apparatus. In that embodiment of the invention shown herein the numeral 9 denotes a bottom bracket arranged to embrace the lower edge of a tub as shown in Fig. 2 of the'drawings, and the numeral 10 denotes a top the upper edge of the tub and to be located above the'bottom bracket 9, a clamp rod 11 being suitably and projecting site bracket and secured as through a hole in the oppoby a clamp nut Specification of Letters Patent.

Hartford and for the purpose of washing* sleeve and being held therein being viding bracket arranged to graspagitator with an outlet' 38 controlled by a- 1s also a vent opening 40 secured to one of the brackets rr eerie.

downward from the bracket. A driving shaft 15 has its bearing in the arm 14; and is drlven as by means of a belt 16 from a motor 17 passlng around a pulley 18 secured to the driving shaft 15. An eccentric 19 or similar device is secured "to the driving shaft 15 and operates a connecting rod op -1' eratively engaging the eccentric at its. lower end and connected with an agitator lever21 at its upper end. This connecting rod is preferably formed in two sections 20 and 22,

the recessed section 22 containing a spring bottomof the recessand 23 restingupon the 20 or the rod.

thrusting against the section The upper end of the rod is adjustably coni nected as at 2 l with the agitator lever.

The agitator lever is on a stud 25 projecting ing from the bracket 10, and is connected with an agitator stem 27 secured to an agitating hood 28. In the form of construction herein shown a sleeve29 is pivotally secured to a socket piece 30 mounted for adjustment longitudinally on the lever 21, the upper end pivotally supported from an arm 26 risof the agitator stem 27 extending within the as by means of a holding screw 31 projecting into an annular groove, (not shown), in the upper end of said stem, so that it may have a rotative movement within the sleeve ing held from lengthwise movement therein. This agitator stem also has a spiral groove 32 preferably formed in an enlargement whilebe therein, a pin 33 projectingfrom within the bearing 34 into said groove, being suitably tending across tion it will be seen rocked the agitatOr stem will be raised and lowered, and by means of the spiral groove and pin will also be partially rotated in opposite directions, the connection between the upper end of said stem and the sleeve29 loose enough, to of the lever 21 and lateral play of the the tub. From this construcment sleeve 29 without binding upon the stem 27.

'- The agitator 28 has a diaphragm 36 proa chamber 37 in the upper end of the valve 39. There I said bearing supported by a bar 35 exg that as the lever 21 is permit rocking movethrough the wall of the chamber 37 into a vent passage ,41. A recessed projection 43 rises from the bottom of the tub and has openings 5 from within the recess to I the outside thereof, this projection preferably removably fitting Within the tub at the bottom thereof. The agitator and projection may be of any desirable form in cross section, as round, rectangular, or otherwise.

A shaft 46is mounted in the lateral projection 13 from the bracket 9 and also in a lateral projection 47 from the'bracket 10,

' this shaft being driven as by means of a l shaft 52, the latter bein'gwemployed. to drive pinion 48 on the-driving shaft 15 meshing with a pinion 49 on the connecting shaft 46. The upper end of the shaft bears a pinion 50 engaging with a pinion 51 on a cross a wringer 53 secured to the tub, the cross shaft being suitably connected as by means 4 of pinions 5455 with a shaft 56 of the wringer. shafts opposite the brackets 9 and 10 are supported in brackets 57-58 that as shown The ends of the driving and cross in Fig. 5 ofthe drawings are of similar construction to the brackets 9 and '10, the arm 26 and lateral projection being omitted from the upper bracket, and the lateral projection from the lower bracket. 'In the form of agitator shown in Figs. 6 and '7 there is a projection 59 preferably extending length- .wise thereof, as particularly shown in Fig. 7.

To effectively remove the dirt from the articles the projection 43 is provided with ribs 42 located on the outer surface of the projection, as shown in Fig. 2.

ile I have shown and described herein a preferred form of construction emb0dy-,

ing my invention, this may be changed to greater orless extent and yet embody my idea, and I do not therefore limit my in vention to an apparatus constructed exactly as shown and described herein.

It will be noted that the beveled pinions are splined tothe shafts to accommodate I themselves to difierent positions of the attachments which they are to drive, these different positions of the attachments being caused by differences in the size of tubs, or otherwise.

I claim 1. In combination with a tub, a pair of brackets arranged for cooperative removable attachment to the tub, the brackets each having bearings off-set from the plane of the brackets for the reception of a shaft, a shaft mounted in said bearings, a driving shaft. mounted in one of said brackets and positioned below said tub, a rock arm mounted in the other bracket above the tub, and connectionsbetween vthe driving shaft and rock arm.

2. In combination with a tub, brackets arranged for attachment to the upper and ed e of the tub, coacti'ng means upon the brackets for securing them together, an arm rising from the upper bracket, .a lever pivotally mounted on said arm, a connecting rod between the driving shaft and lever, an agitator located within the tub, a connection between-said lever and agitator, and

meansfor imparting reciprocating rotary movement to said agitator in the vertical reciprocating movement thereof.

4. In combination with a, tub, a pair of cooperating brackets arranged for removable attachment to the tub,- means for securing the brackets to the tub, one of said brackets having an arm to support a drivsupport a connecting shaft, another arm to ing shaft, and the other of said brackets having an arm to support the connecting shaft and an arm to support an operating lever, the operating lever pivotally mounted to said arm, and an agitator located within the tub and suspended from said arm.

5. In combination with a tub, a pair of brackets secured to the upper and lower edges thereof,.a pair of extensions carried .by each bracket, fastening means associated with cooperating ones of said extensions, a power shaft journaled in one of said lower extensions, a rock arm carried by one of the upper extensions, and a connecting member between the rock arm and power shaft.
