REVERSING MECHANISM FORWASHlNG-MACHlNES.

SPECIFICATION forming part Of Letters Patent'No. 283,586, dated August 21, 1883.

implication filed May 17, 1883. (No model.)

To alt whom it may concern:-

Be it known that I, J rains W. FERNALD, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in'llieversing Mechanism for ashing-Machines, of which the following is a specification. V Figure l is an end elevation, Fig. 2 aside elevation, and Fig. 3 a plan, of my invention.

machines.

My invention consists in an improved construction of reversing mechanism for washing A represents an'iron frame having on one end two brackets, a a, by which the frame is bolted. to the end of a washing-machine.

B represents a shaft journaled in frame A, and having thereon a pinion, G, which on gages with and, drives awheel secured to the shaft, on which the inner cylinder of the wash. ing-machine revolves. 7

1) represents a fast pulley, and E E repre sent two loose pulleys, on shaft B.

ll represents a sleeve fastened to the hub of loose pulley E, encircling shaft B loosely, and carrying at its outer end a worm, ,G, which meshes into a worm-wheel, H, hung on a shaft underneath and at right angles to shaft B.

J represents a wrist-pin fastened to wormwheel H, to which is pivoted one end of aconnecting-rod, I.

K represents a lever pivoted to; frame A at L, the lower end being pivoted'to rod I. At the upper end of lever K is a hook, N.

0 represents a belt-shifter shaped nearly like the letter U, having offsets in which are the holes? P, through which run two belts, one straight and the other crossed, by which power is communicated from a shaftoverhead to shaft B. Beltshifter O has its ends pivoted to frame A, at the points S, by suitable bolts, so that it can be rocked, its range of motion being limited gby small set-screws t t in projections T T on frame A, as clearly shown in Figs. 2 and 3.

Mrepresents a connecting-rod, one end of which is loosely pivoted, at Q, to belt-shifter- O, having in its under side an elongated notch, m, and a smaller notch, :11, both having square or hooked shoulders.

it represents a post rigidly attached to frame A, its upper end being just large enough to snugly fit into notch m in rod M.

The operation of my invention is as follows: Rod Mbeing placed with notch m in hook N, so that the straight belt is on tight pulley D and the crossed belt is on loose pulley E, the drivingshaft is set in motion and shaft B is revolved by fast pulley D. The friction between pulleys D E causes the latter pulley to revolve, thus turning worm G and communieating a slow motion to worm-wheel H. The rotation of wheel H, by means of wrist-pin J and connecting-god 1, causes lever Kto vibrate slowly, and hook N slides along the under side of notch m until it strikes against the shoulder at the outer end of said notch, when, as its moley E and the crossed belt to pulleyD. This 1 reverses the motion of shaft B, while the rotation of pulley E continues in the same direction as before, as it is always actuated, directly or indirectly, by the straight belt. As the wrist-pin J passes either the upper or lower center it will reverse the direction of motion of lever K, and hook N will travel along notch at until it strikes the shoulder at the inner end thereof and shifts the belts to their original position.

Thenit becomes necessary to stop the machine, the belts are locked upon the two loose pulleys by placing notch or in rod M upon the top of post It, which is allowed by the looseness of the pivot at point Q, and all danger of accidental starting of the machine thereby obviated.

What I claim as my invention, and desire to secure by Letters Patent, is y l. The vertical post It, securedin a stationary position to the frame A, in combination with the vibrating lever K, the belt-shipper O, and the rod M, having the notch m in its under side, said rod being loosely attached at one end to the belt-shipper and vdetaohaloly connected at its other end with the vibrating lever, substantially as described.

2. A belt-shifting device consisting of a worm and gear constantly driven in the same direction, a pivoted vibrating lever actuated by the hook, and a connecting-rod pivoted to the beltshifter and removably connected with said vibrating lever, substantially as shown and described.

3. A belt-shifter consisting of a curved rod having holes therein for the passage of the belt or belts, and having its ends pivoted to the frame in which the shaft carrying the pulleys to be affected is .j'ournaled, substantially as shown and described.

4. In reversing mechanism for washing-machines, the combination of the belt-shifter O, connecting-rod M, loosely pivoted thereto, and

having notches a: m therein, and vertical 'p'ost WVitnesses:
