FFIQEG PATENT CONRAD DIETZ, OF COVINGTON, KENTUCKY.

WASHING- MACHINE.

SPEGIFIGATION forming part of Letters Patent N 0. 569,619, dated October 20, 1896.

Application filed July 8, 1893. Serial No. 479,986. (No model.)

To all whom it may concern.-

Be it known that I, CONRAD DIETZ, a citizen of the United States, residing at (lovington, Kenton county, State of Kentucky, have invented certain new and useful Improvements in lVashing-llachines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to that class of washin g-machines having a semicylindrical vibratory receptacle for the clothes and a correspondingly-shaped vibratory dasher for rubbing and turning said clothes, my invention consisting of the means hereinafter set forth for vibrating said receptacle and'dasher from a single crank-shaft.

In the accompanying drawings, Figure 1 is a vertical longitudinal section through a washing-machine embodying my invention; and Fig. 2 is a top view of same, partially broken away. Fig. 3 is a sectional view illustrating a portion of the machine with its lid and dasher elevated, showing the manner in which the connecting-rod is attached to or removed from the clothes-receptacle. Fig. i is a view illustrative of the preferred form of hinge for li1niting the backward movement of the cover when elevated. Fig. 5 is a vertical section on dotted line 5 5 of Fig. 1, looking toward the left hand in said view. Figs. 6 and 7 are enlarged perspective views of the preferred form of device for making the connections between the clothes-receptacle and the pitman-bar.

In the drawings, A represents the outer casing or tub, and B the clothes-receptacle vibratorially connected thereto, the inner face of said receptacle having ribs 1) in the usual manner.

C represents the cover, which is hinged to the tub, and preferably by means of the stophinge shown in Fig. l, one part of said hinge having a hook a, the other having a lateral stud a said hook and stud at each side the machine being adapted to engage with each other to limit the backward movement of the lid. To each inner side face of the cover is attached the bracket-bearing biwithin which the journals (Z of dasher D engage, as more clearly shown in Fig. 5, the outer face of said dasher being ribbed in the usual manner.

The bracket-bearings b are each provided with an elongated groove closed at the top, Within which the journals (Z of the dasher rest. These journals normally rest on the bottoms of the grooves, but are free to yield upwardly a limited distance, the closed top of the grooves absolutely preventing the clothes from forcing the top of the rubber up against the under side of the lid or cover a, which would interfere with the movements of the rubber. The closed grooves also hold the rubber against displacement when the cover is thrown to a vertical or open position. To the cross-piece (Z of the dasher is attached the arm (1", to the free end of which is pivoted one end of the pitman E, the opposite end of the latter being rotatably connected to the crank e of shaft F, which latter is provided with a suitable drive-wheel G. The rotation of said drive-wheel, through the medium of shaft F, crank e, pitman E, arm (Z and crosspicce 61 will cause said dasher to vibrate in opposite directions.

H represents the connecting-rod, which is pivoted at top to the under face of pitman E, the lower end of said rod being pivotally connected to the top edge of one end of receptacle B. In Figs. 6 and 7 I have illustrated the device for pivotally connecting the rod II to said pitman and to the clothes-receptacle, which consists of the plate J having a stud j and a horn or shield j projecting down beneath said stud, as shown, said plate being attached to the under face of pitman E, as shown in Figs. 1 and 3. The plate K is provided with a similar stud 7t" and horn W, said plate being attached to the top cross-piece Z1 of receptacle B, as shown.

The bar or rod H is first pivoted on stud j by swinging said rod out about parallel with plate J, at which time it is readily placed on said stud and swings down at the rear of horn 3' The lower end of said rod is pivoted on the lower stud it by tilting the receptacle upward, as shown in Fig. 3, out of line with the end of horn If, at which time said rod is readily placed upon or removed from said stud.

WVhen the parts are in the position shown in Fig. 1 any movement of crank 6 causes an instant movement to be imparted to the dasher, while the movement imparted to the receptacle is not so perceptible at start; but as said crank moves upward the movement of the dasher decreases, while that of the receptacle increases, and vice versa, as the position of said crank is changed, and at no time is there a stoppage in the movement of both parts so long as motor power is applied.

The protecting-hornsj and 7x3 afford an inexpensive and secure means for retaining the rod H upon its studs when in an operative position, and is readily removed therefrom, in the manner hereinbefore stated, when desired to clean the clothes-receptacle or for any other purpose.

The machine as a whole is simple of construction, cheap of manufacture, and durable in operation.

I am aware that it is not new, broadly, to provide means for operating the clothes-receptacle and dasher simultaneously from a single crankshaft; but

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. In a washing-machine the combination with an outer casing or tub, a ribbed receptacle pivotally mounted in said tub, a top or cover hinged to the tub, and a dasher pivotally mounted in elongated bearings in the top or cover, of a crank-shaft, a pitman pivotally connecting the crank-shaft and rubber, and a rod detachably connected at one-end to one end of the pivoted receptacle, and pivotally connected at its other end to the pitman at a point near the crank-shaft, substantially as set forth.

2. In a washing-machine the combination with an outer casing or tub, a ribbed receptacle pivotally mounted in said tub, a cover hinged to the tub, brackets secured to the inner faces of the sides of the cover and having closed elongated grooves and a rubber having bearings which rest within said elongated grooves, of a crank-shaft journaled in bearings carried by the cover, a pitman connecting the crank-shaft and rubber and a rod detachably connected at one end to one end of the receptacle and detachably connected at its other end to the pitman at a point near the crank-shaft.

3. In a washing-1nachine, the combination with a tub or casing, a cover hinged thereto, a receptacle pivotally mounted in the tub, and a rubber pivotally mounted in bearings carried by the cover, of a crank-shaft, a pitman connecting thecrank and rubber, plates each having a stud and a horn each latter being in a plane adjacent to the free end of its studs, one of said plates being secured to the receptacle and the other to the pitman and a rod mounted at its ends on said studs and retained against accidental displacement by the horns, substantially as set forth.
