WASHING-MACHINE.

Specification of ALetters Patent.

Patented July 2, 1912.

,Application tiled .Tune 20,l 1910. SerialiNo. 567,794.

To all whom it may concern:

Be it known'thatl, ROBERT E. CAMPBELL, citizen of the United States, residing at \Voodland, in the county of Yolo and State of'Ca'lifornia, have invented certain new and useful Improvements in IVashing-Machines, of which the following is a specification.

My invention relates to an improvement in washing machines of the particular style or kind upon which I obtained Lette'rs Patent of the United States'on the 24th day of September 1907, and numberedm866,912.

In theI accompanying drawings, Figure l is a side elevation of the invention, and Fig. 2 is an end elevation thereof looking in from lthe left. tional elevation taken on a line corresponding substantially to Fig. 2. Fig. 4 1s a side elevation of the mangle and pinion, and Fig. 5 is a cross section thereof on line Fig. el.

The machine upon which this improvement is made is a hand machine and designed to be operated exclusively by hand power, but it was Vfound desirable for various reasons to convert the machine into a powermachine so that it can be run without any expense or outlay of personal labor 1n its operation and be connected up with any suitable source of power, such as a small water motor or electric motor or other power that may be available for the purpose.

The invention herein therefore resides essentially in the operating mechanism as it is connected up with the wash tank and other parts'substantially as disclosed in my said patent and as will now appear.

Thus, referring to the said parts, F represents a metallic frame of substantially A shape in side elevation as shown in this instance with the tank T pivoted olf its middle portion or center of gravity at a to be off balance substantially as shown and so as to afford a considerable downward tilting and throw of the long end of the tank as compared with the short end and thus contribute to the tossing of the wash within the tank for cleansing the same, it being understood that so far as the frame vand the tank together are concerned with spring balancing mechanism there is no novelty claimed in this application.

The tension or balancing mechanism for the'y tank upon theframe consists ginl; the.

Fig. 3 is a longitudinal.` sec` spiral spring S and the two sets of

arms

2 and 3 respectively with wlnch'said spring is connected and wlnch 1n turn are rigidly 'mounted on the bottom and center of the frame B which constitutes the immediat-e support of the tank upon the base frame F. The said link or links 2 are projected in a line ofxaboutforty five degrees to the bottom of the tank downward from the short end of the tank .back of its pivot a, While the lilik 3 is shorter and drops from the opposite side of said axis a and extends down to connect with the links 2 approximately near the point of connect-ion of the spring S. The eifect and value of this arrangement is thatby means ofthe spring the tank will be held normally in a horizontal position and the spring will operate to effect this restora-\ tion or position automatically. Therefore the balancing of the tank upon the frame work or base is eifected primarily by the said spring and the said links related as shown and no other mechanism is needed to assist in obtaining this result.

The other parts of the machine shown have to do with the operation or with the power for this purpose, the same, however,

being arranged to cooperate with the said l in the manner shown and described.v

Of course it will be understood that a machine of this kind to get etfective results is necessarily limited in its tilt-ing movement, the idea being that washing of the clothing results from the tossing of the 'same With the water to and fro Within the long tank and in which the wash is cleansed by the agitation in the presence of water under thevright conditions of soap and heat'.

Now, having in view this structure as above described, with everything ready 'to be power operated, I provide a segment-al mangle or rack H supported from the short end of the tank by arms m pivoted upon .the bottom and short end of the tank and having the rack 7 or teeth therein adapted to be engaged between the sides of the mangle by a pinion 8 u )on a power actuated shaft 10. A pulley, s eave or sprocket Wheel, or its equivalent, indicated by 12, is mounted upon this shaft and adapted to receivev power coiinectionsilfrom by beltl or teeth. The said shaft may be provided witha fly-Wheel if desirable ofr .the wheel 12 itself may be 'of'a wveight and construction adapted to serve as a ilyswheel,

s'uch means being necessary With powver, to'

promote 'uniformity of movementpor action in the .tankY an'djto' assist the springS in doing its work in tilting the tankfas well as overcoming dead' center'sfin the mangle, it being4 understood-that thel said., 'spring is.

The machine being pivoted lentirelyv above the ail'efrenders it impossible to operate he coperation 'of the mangleA Withfth'e spring is, thatwhen driven by p ovver the swinging mangle or rack from the short end of the vmachineacts to fix the-exact distance downward of both ends of the tank an makes the action uniorm,-because any suitable source equalize the travel bothways. --Wheel also assists inovercolning the inertia of the shifting load in the tank. The spring position: f y Y The belt N communicates power to the the revers-'e always comes-,lattine same places rin the ends ofthe 11i-angle, Y"and the balance Wheel helps to carry across said ends and Sf also enters into these calculations and isr taken account of in providing a balancey soi thatthe two parts vwill Work in harmony.

The .said springl exerts a constant pressure, holding the swinging mangle t-o the piniony; accelerates thernotion at the ends, prevents deadfcentersr and reducesI friction.
