WASHING-MACHINE 7 Applicationfiled September To all whom it may conccrnzc d i j Be itv known that EMMET B. DIGBY, a citizen of the United States, residing Atlanta, in the county of Fulton and State of Georgia, has invented certain new and useful Improvements in Washing-Machines, of which the following is a specification.

My invention relates to anew and useful improvement in washing machines and has for an object to provide a'machine thattis simplein construction, eflicient in operation and relatively cheap vto manufacture; 1

Another object of my invention is to pro-- vide a washing machine-having t'wocone shaped members located therein to which are imparted a reoiprocated vertical movement as well as a rotary movement-sothat the water and soap suds will be forced through the clothes to thereby dissolve and remove the foreign matter and thus thoroughly cleanse them.

Another object of my invention is to provide a washing machine having two cone members therein to which are imparted a rotary and reciprocal movement and to pro- 7 vide means for imparting these motions that is simple and effective in operation.

With these and other objects in view my invention consists in certain new and novel constructions and combinations of parts as will be hereinafter more fully described and pointed out in the claims.

In the drawings: 7

Figure 1 is a vertical sectional view of my improved washing machine with a portion of the cone broken away for the sakeof' clearness; and

Fig. 2 is a sectional view on line 22 of Fig. 1 looking in the direction of the arrows. 7 Referring now specifically to the drawings, a cylinder or tank 1 of metal or any other preferable material is shown, which is provided with the usual legs 2, the d1scharge pipe 3 and the faucet 4.

Suitably mounted on the outside of the cylinder 1 is a small electric motor 5 which is provided with the pinion 6 which meshes with the drive gear 7 the latter gear being mounted on the shaft 8 supported in the bearings 9.

Extending centrally of the cylinder 1 is the main vertical shaft 10 mounted at its upper and lower ends in the bearings 11. The upper bearing 11 is centrally located on the cross bar 11 which bar is provided Specification of Letters Patent" 8 v Patented Sept. 27, 1921. 7, 1920. Seria1'-No.408,517.

with the. semi-circulararm 11 on which is i mounted one ings9. a

' Rigidly secured to this main shaft 10 and near its upper end is the bevel gear 12 which is designed to be rotated by the pinion 13 mounted on one end of the drive shaft 8. Freely mounted on this shaft 10 and directly beneath the bevel gear 12 is the large cir-' cular cam member 141 which member is tightly held against rotation by the arm 15. A clamp 16 is pinned to the center shaft 10 directly beneath the cam member 14 which clamp has pivotally secured thereto the short arm 17 on which are mounted the two rollers 18 which are designed to travel over the projections and depressionsformed on the lower surface of the cam member 14. Pivotally secured to the outer ends of these arms 17 are the rods 19 which have the heavy springs 20 secured thereto and secured to the other ends of these heavy springs are the arms 21 to the lower ends of which are secured the cones 22. The heavy springs 20 are provided to take up the motion of the arms 19, if the amount of clothes in the tank do not permit a full vertical stroke. Two small springs, 17 connected at their one end to thearms 17 and at their other end to the of the aforementioned bearcollar 16 are shown for holding the rollers 18 against the cam member 14.

As will be noticed the cones are provided at their lower ends with rubber rings 23 or other suitable material so as to prevent any damage to the clothes in the washing machine.

A guide arm 24 is also rigidly secured to the shaft 10 its opposite ends 25 forming bearings through which the arms or shafts 21 operate. This'guide arm provides rigidity to the cones and to their operating arms, adding strength and rigidity to the reciprocating parts. c

.The operation of the machine is exceedingly simple and is as follows: After the clothes have been placed in the tank and the water and soap provided the motor .5 will be started which will, through gear 7 and pinion 13 revolve the bevel gear 12 and its shaft 10. The rollers 18 traveling over the projections and depressions of the cam member provide the reciprocating motion to the cones 22, the cones and cross arm of course also rotating with the shaft 10.

From the foregoing it will be seen that the clothes will be subjected to the pressure of the water as the cones travel downwardly and as is well known it is the water and suds being forced through the clothes that cleanse the same. All of the clothes in the tank will be subjected to the pressure as the cones are revolving at the same time they are being vertically reciprocated. By providing the heavy springs it is not possible to damage the cones should the amount of clothes be so great that they are not permitted to make a full vertical stroke.

Many slight changes may be made without in any way departing from the spirit and scope of the invention.

What I claim as new therefore and desire to secure by Letters Patent is 1. A washing machine comprising a tank,

I a central shaft vertical throughout its length located therein, a bevel gear mounted on said shaft vnear its upper end, a cam member mounted on said shaft and held against rotation, two arms pivotally mounted beneath said cam member and provided with rollers thereon for contacting with said cam member, vertical arms pivotally mounted on said aforementioned arms and provided with a cone member on their ends, a cross arm se- 'a rotary and'reciprocatory motion to said cone members. I

2. A washing machine comprisin a tank, a central shaft vertical throughout its length mounted in said tank, a gear rigidly fastened to said shaft, a cam member freely mounted onrsaid shaft beneath said gear and held against rotation, two horizontally extending arms pivotally secured to'said shaft and provided with rollers adapted to contact with said cam member, vertically extending pivotal arms secured at the outer ends of said horizontal arms, springs secured to the lower ends of these vertical arms, two cone members secured to said springs and a cross arm rigidly secured to said center shaft and having bearings at its outer ends for the reception of the cones, means for rotating said central shaft to thereby impart a vertical reciprocatory and rotary movement tosaid cone members.

In testimony whereof I afiix my si nature. EMMET B. DI BY.
