GEARING FOR WASHING-MACHINES.

Application filed August 25, 1911.

Specification. of Letters Patent.

Patented Apr. 9, 1912.

Serial No. 645,946.

To all whom it may concern:

Be it known that 1, Louis A. brnrirAN, a

citizen of the United States, residing at St.

Louis, State of Missouri, have invented certain new and useful Improvements 111 Gearing' for th ashing-Mitchines, of which the following is :1. specification.

invention relates to on improvement in gearing for washing machines, and the object is to provide an electrically driven shaft having right end left worm gears thereon, which are adapted to mesh with the large gear wheel which is connected. to the agitator ot the washing machine, one of the worm gears engaging; the wheel for causing it to move in one direction as the shaft is rotated, and the other worm gear to engage the. gear wheel for causing it to move in the other direction.

The invention consists in certain novel features of construction and cdmbinations of parts which will be hereinafter fully described and pointed out in the claims.

in the acconu'lunying drawings, Figure l is a view in side elevation showing the invention as applied to a machine; and ltig. 2 is a detail vi w of the connection between the motor on shztit. 7

it, represents a washing machine, and 'l is a support mounted upon the'niachine in which is journaled a shaft 2', to which is connected the agitator (not shown). A gear wheel 3 is connected to the shaft, which rotated for agitating theegitator. A rotat ing shaft t is supported by the support 1, and slidahiy mounted upon the shaft is a sleeve having a. left-hand worm gear 5 at one end and n right-trend worm gear 6 at the other, these gears being; suiliciently spaced sport so that one can be thrown into engagement with the large gear 3 without intertert-ince from the other. worm gear whereby the large gear wheel 3 can be- .caused to rotate first in one direction and then in another.

A gear wheel 7 is mounted upon the shaft and is driven by u, worm 8 on a shaft 9. ".ihc shaft 9 carries a gear Wheel 10 which is driven/by r. geer 11 on the shaft of the motor 12. A frame- 13 is connected to the machine for supporting the motor.

All annular groove 10 is formed at one end of the sleeve 1?, and loosely connected to thenleeve B and fitted in the annular groove 16 is n link 17, which i eccentricnlly con uectcd to the worm whee... 14 by it hnk 17 When the shaft {is caused to rotate the worm 15 will cause the worm wheel 14 to rotate, and as the worm wheel 14; rotates,

the link 17* will be given anendwise recip-' rocnting movement, causing the sleeve B to be reciprocated,causing one of the worms. to engage the gear 3 for causing the gear to be rotated. When the wheel 14. has completed half a revolution, the worm which is in engagement with the gear wheel. 3 becomes disengaged, and the other worm is brought into engagement with the gear wheel 3, for the remaining half. revolution of the wheel 14, causing the gear wheel 3 to rotate in another direction;v andthen at the. next half revolution of the wheel 14:, said first-named Worm will again be brought into engagement with the gear wheel 3. This operation is continued as long as the shaft 4 is rotated.

It is to be noted that the worms fiend (l are spaceda. sufiicient distance apart to in sure the disengagement of one of the gears before the other worm makes a. positive engage nent with the gear wheel 3, causing it to rotate. in an opposite direction from that hilten when in mesh with the first gear.

lilaving fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The conlhinntion with a main shaft and means for driving said shaft, of axsecondary shaft, a gear wheel mounted on the secondary shaft, it double worm slidably mounted on the main shaft adapted to mesh with the gear wheel, n worm wheel, means on the main shaft for driving the worm wheel, and means connecting the worm wheel to the double worm, whereby first one of the worms and then the otherwill be thrown into en gageuient with the large gear wheel during the rotation of the worm wheel.

:2. The combination with a. main shaft and means for driving'said shaft, of a secondary shaft, a gear wheel mounted on the secondary shaft, a. double worm slidably mounted on the main shaft adapted-to mesh with the gear wheel, a worm wheel, a worm on the main shaftmeshing with the worm wheel and means connecting the worm wheel to the double worm, whereby each ofthe Worms will he brought into engagement with the gear wheeltor rotating it in two directions during one revolution of the worm wheel.

menus for driving the shaft, of a secondary 3; The combination with 0. main shaft and' shaft, a gear Wheel mounted on the secondment with the gear wheel during the rota.- zu'y shaft, a double Worm slidebly mounted tion of the Worm Wheel. 10 upon the main shaft, a worm heel, means In testimony whereof I affix my signaon the main shaft for driving the worm ture, in the presence of two Witnesses.

Wheel, and a link connected to the double 4 LOUIS A. STEPHAN. Worm and eccentrically connected to the VVit nesses:

then the other will be thrown into engage- CHAS. KOCH.
