REVERSING MECHANISM.

.3PEOIFICATION forming part of Letters Patent No. 653,811, dated July 17,1900. Application l d February 28, 1900. Serial No. 6,792, (No model.)

To aZZ whom it may concern:

Be it known that 1, JOHN KERKHOFF, a citi-. zen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented an Improvement in Reversing Mechanism for Washing-Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

My invention relates to reversing mechanism for washing-machines; and it has for its object the improvement in the construction of such machines whereby they are simplified and rendered more efficient in action.

The novelty of my invention consists in the combination and subcombination of the parts, as will be hereinafter set forth, and specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of a reversing mechanism, showing the washer-tub in section. Fig. 2 is an end view of a reversing mechanism, showing part of the bracket broken away. Fig. 3 is a rear view of locking device for beltshifter.

Similar letters of reference indicate like parts throughout the several views of the drawings.

The shaft A has all the moving parts of my reversing mechanism attached to it, except the gear B, the gear B being keyed to the trunnion O. The trunnion 0, being secured to the cylinder D, revolves in a suitable hearing, which is attached to the head of the tub E. Then the gear B revolves, it causes the cylinder D to revolve, motion being transmitted from gear B to cylinder D through the trunnion O. The pinion F is keyed to the shaft A. The pulleys G and H run loosely on the shaft A. The pulley I is rigidly attached to the shaft A. with a set-screw, so that when shaft A revolves pulley I revolves also.

The pulley H has a thread or worm J attached to the outer end of its hub, and the worm J, attached to the hub of pulley H, meshes with a worm-gear K. On the face of worm-gear K is a cam L, which works in the opening M at the lower end of the arm N. The arm N is pivoted at about the central point between the cam L and a pin 0, projecting in from the top of arm N. The arm N is pivoted to the projeotin g arm Pof the adjustable bracket Q. The worm-gear K has ahub R, which revolves in a bearing S, the hearing S being part of the arm T, which extends down from the adjustable bracket Q. The worm-gear K is held in position by a capscrew U, which screws into the hub R of the worm-gear K.

The upper part of the adjustable bracket Q has a projection V, to which the rest '0 is attached. The head '0 which carries the beltshifter, slides on the resto. Passing through the head r is a semicircular piece of iron o to which the belt-shifter loops o are attached. The head o is attached at its upper part to the end of slidable rod 17. The slidable rod 6 passes through the boss 12 at the top of the adjustable bracket Q. Attached to the rod 12 is a dog 17 At the outer end of the rod 1) there is a weight or handle I) for throwing the reversing mechanism in gear or out of gear.

To support the outer end of shaft A and is as follows: Two belts, a cross-belt and a straight belt,are used to operate this reversing mechanism. There would be a cross-belt on pulley G and a straight belt on pulley H. The belt on pulley H would revolve the pulley H, and as the worm J is a part of the hub of pul ley H the worm J would revolve also. As the worm-gear-K meshes with worm J ,it would revolve, causing the cam L to revolve with it, and as the cam L revolves in the space M of the arm N it would cause the lower part of arm N to oscillate back and forth, and as the arm N is pivoted to P at about its central point the upper part of arm N describes the arc of a circle of about the same size as the lower part of the arm N did. When the dog 11 is turned over, so that the slot b catches on the pin 0, it causes the rod 12 to slide back and forth, and as the belt shifter o is attached to the rod 1) it causes the belts to alternately shift onto the tight pulley I, revolving the cylinder D two or three revolutions in one direction, and then reversing and revolving two or three revolutions in the opposite direction. \Vhen it is desired to stop the machine from working, the dog 12 is turned back into the space I), in which position it holds the belts versing mechanism, of two loose.pulleys,'and.

one tight pulley, one of the loose pulleys having a worm attached to the outer end of its hub, which meshes with a wormegear, r the worm-gear having a cam projecting from one side that works in an opening at the lower end of a vertical arm, the vertical arm being pivoted at-its center to a bracket, the upper end of thevertical arm having a pin-project ing in fromthe top to engage with a slot which is in: the lower side of iaidog,.the d'o'g being secured to a rod, this rod having attached to it at one end ahead, this head having a beltshifter projecting laterally and downward from it, each end of the belt-shifter being providedwit-h belt-loops to engage belts, a weight secured at the opposite end of the above- -.named rod, a pinion on the same shaft with the tight and loose pulleys, this pinion meshing with a gear that is secured to the cylinder of the'washer; substantially as described.
