OPERATING MECHANISM FOR WASHING-MACHINES.

Specification of Letters Patent. Iaten ted Aug. 31, 1909 Application filed May 24, 1909. Serial No. 49 8,120.

To all whom it may concern:

Be it known that I, HUoo G. BRAUNLICH, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful 'In'iprovements in Operating stored-up energy in the fly-wheel diminishing the work of operating the machine after it has once been started.

My improved mechanism is operatedby a lever so that the operator has a simple back and forward or up and down movement of the hand in using the device.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

In the drawings il-lustratil'ig this invention :Figure 1 is a view in side elevation of a washing machine embodying my invention. Fig. 2 is a plan view of the same. Fig. 2-3 is a vertical sectional view taken upon line 3-4:; of-Fig.

My improvements are herein shownas applied to the particiilar construction of machine illustrated in the prior U. S. Letters Patent to'Schroeder issued on the 12th of March, 1895, wherein the shifting or movable gear of the ilanetary gear mechanism is mounted on the operating shaft, but may be applied to other n'iaehines of this general type.

In thedrawings, 5 designates a washing machine tub of any usual form mounted upon supporting legs (3, ti and provided with a hinged lid 7 upon which is supported the operating meehanisnr hereinafter referred to. Mounted upon the lid 7 is a. base plate 8 which is provided at its 'iniier end with a vertically arranged shell 9 in which is retativelv supported an operating shaft "10 which depends into the tub and has therein keyed to it an agitator 11 of familiar form. A sleeve 12 is feathered to the shaft 10 within the shell 9 so as to rotate with said shaft while being at the same time movable vertically thereon. Said sleeve or cylinder is provided with radially arranged teeth or roller bearing pins 12 which are adapted to mesh with'a spur gear 13 carried upon the inner end of a continuously rotating drivin shaft 1- The said driving shaft is supported at its inner end in a bearing formed in the shell 9 and at its other end in a vertical standard 16.. In operation, the spur gear 13 engages first the upper side and then the lower side of the teeth or hearing pins to rotate the shaft 10 alternately in opposite directions, the sleeve or cylimler 12' being caused to rise and fall at the limits of the movement of the shaft 10 in a well known manner to present the opposite sides of the teeth or bearing. pins alternately to the spur gear as in the aforesaid Schroeder construction.

Secured t0 the outer end of the driving shaft 14 is a gear wheel which is given continuous rotary motion by means of a. prime mover 2-1. Said prime mover consists of a rocking lever comprising two arms 22 and 23, one of which, 22, is operatively connected with the gear wheel 20 by means of a link or pitman.24 and the other arm of which, 23, is provided with a socket for receiving an operating handle 25. A fly-wheel 30, which is rotatively supported upon the tub lid 8 and independently of the prime mover, is provided-on its hub with a gear pinion 31 which is in mesh with the teeth of the gear wheel 20 and by means of which the said fly-wheel is driven continuously in one direction.

A suitable sup mrting plate 32 is secured to the lid of the tub and is provided with outwardly projecting hubs and 34, the former supporting 'a pivotal stud 35 upon which the prime mover 21 is mounted and the latter supporting a pivotal stud 36 upon which the flywheel 30 is mounted.

In the operation of the machine, the rock ing. motion of the prime mover 21 is translated into continuous rotary motion of the shaft 14 by means of the pitman 24; and the gear wheel 20. The rocking motion of the said prime mover is also translated into continuous rotary motion of the fly-wheel 30 through the gear wheelZt) and the pinion 31 on the hub of the saidfly-Wheel and the proportions of said gears are such that the fly- Wheel is rotated at a s eed considerably higher than that of the sliaft 14. As a result of the increased speed thus given to the fly-wheel and of its weight, the momentum ofthe rotating Wheel serves to give to the driving shaft a smooth and uniform rotation'and prevents the shocks, due to the reversal of the agitator shaft, from being perceptibly transmitted to the prime mover. ,The tendency to retard the movement of the parts and the consequent loss of power at the points of reversal is also avoided by this construction.

1 claim as my inventionz- 1. Means for operating a Washing machine, comprising in combination an operating shaft capable of rotary reciprocating motion, a gear mounted on the operating shaft, 1 driving shaft arranged to be drivei'i continuonsly in one direction, a spur. on said shaft 7 which meshes alternately with the opposite sides of the gear on the operating shaft to translate the continuous rotary motion of the said driving shaft into rotary reciprocating motion of the operating shaft, an actuating lover, a fly-wheel and means for translating the rocking motionof the actuating lever into continuous rotary motion of the driving shaft and into continuous rotary motion of the fly-wheel.

wheel, a fly-Wheel mounted independently of the operating lever and operatively connected with the said gear wheel.

3. Means for operating a Washing machine, comprising in combination an operating shaft capable of rotary reciprocating motion, a gear mounted on the operating shaft a driving shaft arranged to be driven continuously in one direction, a spur gear on one end of the driving shaft which meshes alternately with the opposite sides of the gear on the operating shaft to translate the continuons rotary motion of the driving shaft into rotary reciprocating motion of the operating shaft, a gear wheel on the opposite end.

of the driving shaft, a rocking actuating lever, a pitman connecting said actuating lever with said gear wheel, and a flywheel mounted independently of the said actuating lever, and provided on its hub with a gear pinion engaging the teeth of the said gear wheel.

at. The combination with an o )erating shaft, ofa driving shaft arranged to be drivencontinuously in'onc direction and adapted to give rotary reciprocating motion to the said operating shaft, a rocking actuating lever adapted to rotate the driving shaft, a flywheel mounted independently of the actuating lover, a supporting plate hav ing (mhwn'dly projecting hubs formed thereon, pivotal studs supported in the said hnhs upon which are severally mounted the actnating lever and the fly-wheel, a gear mounted on the driving slreift, a pitman connecting the actuating lever and said gear, and gear connections between said driving shaft and said operating shaft.

In testimony, that I claim the foregoing as my invention I atlix my signature in the presence of two witnesses, this 19th day of May A, I). 1909.
