WASHING-MACHINE.

Specification of Letters Patent.

Patented Jan. 23, 19117..

Application filed October 20, 1916. Serial No. 126,706.

To all whom it may concern:

Be it known that 1, JOHN A. STENsnUD,

a subject of the King of Great Britain, re-

siding at Scotsguard, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Washing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in washing machines and the principal object of the invention is to provide a washing machine which may be hand or power operated.

Another object of the invention is to provide a washing machine in which the tub rotates simultaneously with the reciprocating action of the agitator or rubber.

A further object of the invention is to provide a washing machine having a spring balancing means for assisting in the operatian of the device.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure l is a vertical section through a washing machine constructed in accordance with this invention. Fig. 2 is a top plan view of the washing machine. Fig. 3 is a sectional view on line 33 of Fig. 1. Fig. 4 is a sectional view on line 4& of Fig. l, and Fig. 5 is a detail view illustrating the method of securing the reciprocating rubhers to the operating standards therefon.

Referring to the drawings the numeral 1 designates the frame of the device consisting of a plurality of supporting legs 2 secured to or formed integrally with the hub member 3. This hub member is provided in its upper face with an annular ball race 4 in which the bearing balls 5 are mounted. A central opening 6 is formed in the hub 3 and attached to the legs near their lower ends are the brace bars 7 A suitable bracket designated generally by the numeral 8 and consisting of the horizontal arm 9 and the inclined brace arm 10 is secured to one of the legs and forms the supporting means for the operating wheels and levers which will be more fully hereinafter described. An angular extension 11 is formed at the upper free end of the arm 10 and forms a support for the operating lever to be more fully hereinafter described.

Secured to the arm 9 near its outer end is a stud 12 on which the gear wheel 13 is mounted while a suitable shaft 1a is journaled in the arm near its inner end and carries at one end a pinion which meshes with the gear 13 and at its opposite end is mounted a suitable belt wheel 15 for driving the device from any suitable power. In order that the lever 16 may be operated to control the movement of the washing machine the same is pivoted as at 17 to the arm 11 and has pivotally connected at 18 the link 19 which is pivotally connected at 20 to the gear wheel 13. It will thus be seen that when the gear wheel is driven the lever 16 will be swung on its pivot 17 thereby operating the washing machine. The upper end of the lever 16 is provided with a hand hold by means of which the same may be manually worked.

Rotatably mounted on the ball bearings 5 is a plate 21 which supports the tub 22 and allows the same to freely rotate. Secured centrally of the tub and rotatably mounted in the opening 6 of the hub 3 is a hollow cylindrical shaft 28 carrying at its lower end a pinion 24. This pinion meshes with the rack bar 25 which is slidably mounted on the legs and this rack bar is provided on two of its adjacent faces with suitable rack teeth as clearly illustrated in Fig. 4. As shown in Fig. 3 it will be seen that the teeth on the inner face of the rack bar 25 mesh with the gear 24 and the teeth on the under side of the rack bar mesh with the teeth of the pinion which will be more fully hereinafter described. Formed integrally with the ends of the rack bar are the arms 26 which have formed at their ends the inwardly extending projections 27 which are slidably mounted in suitable brackets 28 carried by the legs 2 which form guides for the device so that the bar 25 will be held in proper position. The ends of the extensions 27 which project beyond the inner faces of the brackets 28 are surrounded by compression coil springs 29 which abut the adjacent faces of the brackets 28 and the pins 30 carried near the extreme ends of the extensions. It will thus be seen that the springs tend to act against each other thereby holding the device in the position illustrated in the drawings. Formed on one of the arms 26 near the point where the extension 27 joins the same is a suitable ear 30 to which is pivotally connected the link 31, the opposite end of which is pivotedas at 32 to the lever 16. It will thus be seen that when the lever is operated the rack bar 25 will be slid through the bracket 28 in a reciprocatory manner thereby rotating the gear 24 and causing the tub 22 to oscillate.

Simultaneous with the operation or oscillation of the tub 22 the agitator or rubber is reciprocated by means of the vertically slidable bar 32 which is mounted Within the hollow shaft 23. This bar 32 is provided on one face with a plurality of rack teeth 33 which mesh With the pinion 34 which is secured to the shaft 35 which in turn is rotatably mounted on the bracket 36 carried by one of the legs 2. This shaft 35 carries at one end the pinion 34 and at its opposite end a gear 37 which meshes with the teeth on the under face of the rack bar 25. It will thus be seen that when said rack bar is reciprocated the gear 37 and pinion 34 will be driven. The upper end of the rod 32 is provided with the rectangular portion 38 and this rectangular portion is in turn formed with a threaded extension 39 on which the wing nut 40 is threaded. A suitable sleeve 41 surrounds the hollow shaft 23 and is provided at its upper end with the wall 42 having a central rectangular opening therein for the reception of the extension 38. A washer 43 is positioned on the upper side of the end wall intermediate the wing nut 40 and the end wall 42 and it will thus be seen that the sleeve 41 will be firmly clamped on the rod 32. The sleeve 41 is of such a diameter as to fit over the shaft 23 so that the same will be free to reciprocate thereon. Formed integrally with the sleeve 41 near its lower end are the spaced ears 44 which are arranged in pairs and at diametrically opposite Points and pivoted between these ears are the arms 45 which support the agitator or rubber designated generally by the numeral 46. This agitator or rubber consists of a disk 47 of a suitable corrugated material which is supported by the arms 45 and it will thus be seen that when the machine is in motion the rubber will be held against rotary movement but yet will move in a vertical path and through the rotary movement of the tub it will be seen that the lothes placed between the bottom of the tub and the under side of the rubber will be thoroughly cleansed.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claim.

What is claimed is In a washing machine, a base, brackets supported on the base, a bar slidably mounted beside the base, extensions on the bar slidable in the brackets, springs surrounding the extensions for balancing the bar, means to reciprocate said bar, rack teeth on the inner and lower faces of the bar, a hollow shaft journ'aled in the base and extending upwardly therethrough, a tub rotatably supported on the base and attached to said shaft, a pinion on thelower end of the shaft meshing with the rack teeth on the inner face of the bar, a, hollow sleeve slidable over the upper end of the hollow shaft, a rack bar slidable through the hollow shaft and connected to the sleeve, a corrugated rubber secured to the lower end of the sleeve and means driven from the under face of the first mentioned rack bar to cause the second mentioned rack bar to reciprocate simultaneously with the oscillation of the tub.

In testimony whereof I aflix my signature in presence of two witnesses.

' I JOHN A. STENSRUD.

A. F. MACDONALD, JAMES REYNOLDS.
