MEANS FOR OPERATING WASHING-MACHINES.

. SPECIFICATION forming part of Letters Patent No. 687,394, dated November 26, 1901.

Applibati'on filed March 29, 1901. Serial No. 53,436. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. BUEGGE, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Means for Operating 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 appertainsto make and use the same.

My invention relates to an improvementin operating mechanism for washing-machines of the type in which the rotary movement of the clothes-agitator is reversed; and its object is to provide means to cause the agitator to have only a partial revolution and to also provide a novel and superior mechanism to insure the reversible rotation of the agitatorshaft.

The invention consists in the combination and arrangements of parts the construction and operation of which will be more fully described in the following specification and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of the operating mechanism applied to the top of a washing-machine. Fig. 2 is a top view of Fig.1, showing in dotted lines another position of the parts assumed in its movements. Fig. 3 is a cross-section on the line 00 m of Fig. 2.

Like numerals of reference indicate corresponding parts throughout the several views.

In the drawings, 1 represents the top of a washing-machine, and 2 the agitator secured to the shaft 3, which is journaled in suitable bearings 4 and 5, connected with the supporting-frame 6. Secured to the upper end of the shaft 3 is a bifurcated crank-arm 7, being held rigid on the shaft by the pin 8. Pivotally hung within the bifurcation of the crank-arm 7 is a driving-arm 9, provided with the depending right-angular nose 9. Revolubly mounted upon the standard 12 is a horizontally-disposed driven gear 10, having the boss 10 and the stud 11', which forms a journal for the pivotal connection of the drivingarm 9, the gear and arm being held to their bearings by the pins 13.

14.- represents a driving-shaft mounted in suitable bearings 15 in the frame and having keyed to its outer end the fly-wheel 16 and to its inner end the drivingear l7,which meshes with the gear 10. Mounted upon the shaft 14 and revolved therewith is a detent 18, having long and short oppositely-disposed arms 19, each provided with a bifurcated or forked end,as indicated at 20, and the forked end of the long arm is adapted to engage the end of the driving-arm at every one and one-half revolution of the driving-shaft, while the nose-9 will engage within the bifurcation of the short arm at every two and one-half revolutions of the driving-shaft; but whenever the driving-arm or its nose is engaged by the detent the driving-arm and crank-ar1n will be at a dead-center, which is overcome by the rotation and engagement of the detent with the said arm. As shown in full lines in Fig. 2, the driving-arm is engaged by the long arm of the detent and the pivotal connection with the "driving-arm and crank 7 being at a dead-center. The forward end of the driving-arm will be thrown forward by the long arm of the detent, thereby throwing the pivotal connection A in a reverse direction and off the dead-center, and as the gear continues its revolution it will assume the position shown in dotted lines. The driving-gear 17 being smaller than the driving-gear 10, the former will make one and one-quarter of a revolutions, while the driven gear (desig nated 10) makes only one revolution. Now as the crank arm continues to move forward from the position shown in dotted lines in Fig. 2 it will again assume the position shown in full lines; but the dead center will be overcome by the nose 9 of the driving arm engaging the bifurcation in the short arm of the detent, as shown in Fig. 3; but the pivotal connection A will be thrown in the opposite direction and impart a reverse partial revolution to the agitator-shaft. This is accomplished by the short arm of the detent slightly retarding the movement of the forward end of the arm; but the driven gear will continue to move until the pivotal connection A is thrown off its dead-center and in a reverse position to that shown in dotted lines in Fig. 2. It will be understood that at every one and one-quarter revolutions of the driving-shaft and its gear the driving-arm will be engaged alternately by the long and short arm of the detent, and atevery two and one-half revolutions the driving-arm will be engaged by either the long or short arm of thedetent. 'lhismovementwillimpartabout a two-thirds revolution to the agitator, the crank-arm making a full strokeat every one and one-quarter revolutions of the drivinggear.

While I have designated my invention as applied to a washing-machine, for which it is more particularly adapted, it may be applied to churns, ice-cream freezers, or any other device in which an oscillatory movement is required for the driven member, and changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit of my inven tion or sacrificing any advantages thereof.

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

1. In an operating mechanism for Washingupon the driven gear, a driven shaft, a crank- 1 arm carried thereby pivotally connected with the driving-arm, and means upon the drivingshaft for imparting a reverse partial revolution to the driven shaft.

3. In a mechanical movement, the combination with a driving-shaft and a driven shaft, of a driving-arm connected with the driven shaft, and a driven gear adapted to operate the driving-arm, a detent mounted on the driving-shaft and adapted toengage the end of the driving-arm'andcause the-same to overcome a dead-center.

4. The combination with a driving-gear and a driven gear, of a driving-arm operated by the driven gear, and a driven shaft, a crankarm mounted upon said shaft and in pivotal connection with the driving-arm, a'detent mounted on the shaft of thedriving-gear, and provided with long and short arms, each of which is adapted to alternately engage the end of the driving-arm and impart a reverse rotation to the driven shaft.

5. In a mechanical movement, the combination with a driving-gear and a driven gear, of a driven shaft, a driving-arm connected with the driven shaft and driven gear and provided with a depending nose, a detent composed of long and short arms, the ends of which are bifurcated the long arm adapted to engage the end of the driving-arm and the short arm adapted to engage the nose of the driving-arm to overcome the dead-center of the driven members.

6. In an operating mechanism for washingmachines, driving members and driven members, a driving-arm permanently attached to and connecting the driven members, mechanism mounted upon one of the members to be temporarily engaged by the driving-arm at predetermined intervals to insure the reversed rotation of the driven members, and means to cause one of the driven members to have a partial revolution.

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

JOHN H. BUEGGE.
