GEARING FOR WASHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 761,951, dated June 7, 1904. Application filed October 13, 1903. Serial No. 176,874. (No model.)

To all whom it may concern:

Be it known that I, HER AN JOHN DUVE, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Gearing for Washing-Machines, of which the following is a specification.

This invention has relation to washing-machines; and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide a washing-machine having a shaft adapted to rotate in fixed bearings, said shaft being provided with -a gear-wheel adapted to engage pins or teeth on a collar surrounding the dasher-shaft. A yoke is fixed to the dashershaft, and the said collar is pivotally supported at an intermediate point to said yoke. The said collar is provided with an upper and lower set of gear-teeth or pins and an intermediate horizontal rib with curved flanges located beyond the ends of said rib. The horizontal shaft is provided with a gear-wheel which is adapted to engage alternatively the upper and lower sets of gear-teeth of the said collar, the end of the said shaft extending past the edge of said rib and adapted to hold the gearwheel in engagement with the lower set of gear-teeth of the collar. The side of the said gear-W heel is provided with pins or lugs, which are adapted to come in contact with the curved flanges of the collar, and thus oscillate the said collar, whereby the said dasher is caused to rotate back and forth, while the horizontal shaft rotates continuously in one direction.

.In the accompanying drawings, Figure 1 is a vertical sectional view of the washing-machine. Fig. 2 is a top plan View of the same. Fig. 3 is a vertical sectional View of the oscillating collar and its attachments. Fig. 4 is a side elevation of said collar flattened out, showing the relative positions of the gear-teeth, rib, and flanges and also showing one position of the gear-wheel (in dotted lines) with relation to said collar. Fig. 5 is aview of the collar the sameas Fig. 1, showing the relative position of the gear-wheel (in dotted lines) when about in the act of oscillating saidcollar.

The tub 1 is mounted on suitable legs 2 and ings 16 and 17.

is provided with a hinged top 3. The dasher 1 is fixed to the lower end of the dasher-shaft 5, which passes vertically through the center of the top 3. Said dasher-shaft 5 is journaled in the bearings 6 and 7 The yoke 8 is fixed to the dasher-shaft 5, and the collar 9 surrounds the said dasher-shaft and is pivotally connected at an intermediate point to the yoke 8, as at 10. The said collar 9 is provided with an upper set of gear-teeth 11 and a lower set of gear-teeth 12, and midway between the two sets of said gear-teeth is located a horizontal rib 13. The said collar 9 is alsoprovided beyondthe ends of the rib l3 with the curved flanges 14.

The shaft 15 is adapted to revolve, but is held in fixed horizontal position by the bear- The gear-wheel 18 is attached to said shaft 15, and the inner end of said shaft extends past the outer edge of the rib 13.. The inner face of the gear-wheel 18 is provided with the pins or lugs 19, which are not long enough to engage the rib 13 as the said gear-wheel 18 rotates, but are adapted to engage the curved flanges 14: and oscillate the collar 9, as will be hereinafter explained.

The shaft 15 may be provided with a hand operating wheel 20-, as shown in Fig. 1, or if it is desired to operate the washer at a faster rate of speed the said operating-wheel 20 may be attached to a shaft '21, upon which is located a larger gear-wheel 22, which meshes with a smaller gear-wheel 23, located upon the shaft 15. The machine may be operated by hand or power, as desired.

The operation of'the machine is as follows: i

The shaft 15 rotates in fixed horizontal position, the gear-wheel 18 engaging one of the sets of gear 11 or 12 of the collar 9. The said collar is carried around, Which through the yoke 8 causes the dasher-shaft 5 and dasher 4 to make a partial rotation. VVheu the end of the rib 13 is brought to a point beyond the end of the shaft 15, one of the lugs 19 comes in contact with the inner surface of the curved flange 14, and the said collar 9 is moved either up or down, (according to the direction on which the shaft15 is turned) and the teeth of the said ge'ar-wheel18 will engage the other set of gear-teeth on the collar 9 and cause the said collar and its attachments to rotate back in the opposite direction.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A shaft adapted to rotate continuously in one direction, a second shaft adapted to rotate back and forth, a yoke having both its ends engaging the last said shaft and an intermediate portion bowed away from said shaft and adapted to move With said shaft, an oscillating collar located upon the last said shaft said collar being pivotally supported at a point intermediate the ends of the said yoke, and a suitable connection between said collar and the first said shaft.

2. A shaft adapted to rotate continuously in one direction, a gear-wheel located upon said to this specilication in the presence of two suhscribing witnesses.

HERMAN JOHN DUVIG.
