EUGENE L. IIOVE, OF MUSKEGON, MICHIGAN, ASSIGNOR TO THE MICHIGAN VASHING MACHINE COMPANY, OF MUSKEGON, MICHIGAN, A CORPORA- TION OF MICHIGAN.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent N o. 711,317, dated October 14, 1902.

Application filed February 7, 1901. Serial No. 46,460. (No model.) I

T all whom, it may concern:

Beit known thatl, EUGENE L. HOWE, a citizen of the United States, residing at Muskegon, in the county of Muskegon and State of Michigan, have invented a new and useful Washing-Machine, of which the following is a specification. f

This invention relates to washing-machines. The object of the invention is to provide a xo construction and arrangement of wash-ingmachine and operating means therefor which are simple and efficient in operation.

The invention consists, substantially, in the construction, combination, location, and arrangement, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.

Referring to the accompanying drawings and to the various views and reference-signs appearing thereon, Figure l is a plan view of a washingmachine, showing the application thereto of an operating-gearing and mechanism embodying the principles of my invention. Fig. 2 is a vertical central longitudinal section of the same. Fig. 3 is a detached detail View, in vertical section, illustrating the stop for maintaining the operating-rack in engagement with the operating-pinion of the stirrer-shaft. Fig. 4 is a detached detail View, in side elevation, showing the stop.

The same part is designated by the same reference-sign wherever it occurs throughout the several views.

3 5 Reference-sign A designates a washtub. or

other receptacle, which may be of any suitable or usual construction and shape.

B designates the top or cover of the tub, suitably hinged at one side or edge thereof to a stationary or fixed part of the tub.

C designates a casting or bracket suitably bolted or otherwise secured to the hinged door B. B designates a similar bracket or casting suitably bolted or otherwise secured to a fixed part of the top or end of the tub A.

These brackets or castings are suitably hinged together, as at E, and constitute the hinges for the cover B. The casting C is provided with a hub F, arranged at a point preferably in central relation with respect to the tub, 5o said hub being arranged to extend through the top or cover B and forming a bearing for a shaft G, said shaft being arranged to eX- tend into the tub A and carrying a stirrer H, which stirrer may be of the usual or ordinary or well-known construction and arrangement. The casting or bracket D is provided with a journal-stud J, upon which is mounted an operating or driving means, such as a handwheel K. Formed on or suitably connected 6o with the wheel K is a bevel-pinion L,arran ged to mesh with and to rotate a coperating t bevel-gear M, suitably journaled upon a stud N, formed on or carried by a casting or bracket D. Suitably hinged or pivoted at one end eccentrically upon the face of gear M, as at O, is an arm or bar P, having rack-teeth, as clearly indicated in Fig. l, and which rackteeth are arranged to engage or mesh with the teeth of a pinion Q, carried upon the pro- 7o jecting end of stirrer-shaft G. The rack-bar l may be held in engaging relation with ret spect to pinion Q in many specifically different ways. It is desirable, however, that said rack-bar be so held in engaging relation with respect to said pinionthat it may be readily detached from such engagement when desired.

-I haveA shown a simple and efficient manner for accomplishing this result, to which, however, my invention is not to be limited or re- 8o stricted and wherein I provide a stop-pin R, having a forked end, the'arms S T of which 1 are arranged to straddle a web or iange A', formed on or suitably connected with the bracket or casting C of the hub F thereof, said web or flange being provided with a seat (indicated by a dotted line in Figa) and also being slotted, as at B. A piu C', carried by the stop R, is arranged to operate in the elongated slot B. The operation of this part of 9o my invention is as follows: When it is desired to hold rack-bar P in engagement with pinion Q, the pin R is seated in the seat of flange or web A in position to maintain the rack-bar I?, with the rack-teeth thereof, in engagement with the pinion. Under these conditions the t pin C occupies the lowest position thereof permitted by the elongated slot B', as clearly shown in- Fig. 3, and the bottom of the fork of stop R is received within the seat in the upper edge of web or flange A', thus forming an efficient bearing for the stop, and hence maintaining the rack-bar in engagement with the pinion. When it is desired to detach the rack-bar from the pinion, the stop R is raised until the bottom of the forked end thereof clears the top edge of web or bracket A or the seat therein, the pin C traveling or moving in slot B until said stop may be swung back out of the way to permit the rack-bar to be disengaged from the pinion.

When the rack-bar is held in engagement with the pinion,byimparting rotation to han dwheel K rotary movement is transmitted to gear M, thereby imparting an oscillatory reciprocation to bar P, the pivotal connection of said bar to the face of gear M permitting the oscillations thereof. The longitudinal movements or reciprocations of bar P effect rotary oscillations of stirrer-shaft G and stirrer H. It will be observed that the stirrer-shaft and stirrer are supported by the hinged cover of the tub. If desired, lthe cover may be locked in close relation with respect to the tub in any suitable or convenient manner. I have shown at D a simple and eflicient locking device for this purpose; but it is obvious that other forms of locks may be employed without departure from the spirit or scope of my invention.

From the foregoing description it will be seen that I provide an exceedingly simple and eicient construction of Washing machine wherein the gearing is of few parts and can be cheaply manufactured and assembled and wherein the driving-gearing may be readily disconnected from the stirrer-shaft when desired for placing the clothes or other articles to be washed within or removing the same from the tub.

Many variations and changes in the details of .construction and arrangement of parts would readily occur to persons skilled in the art and still fall within the spirit and scope of my invention. I do not desire, therefore, to be limited or restricted to the exact details shown and described; but,

Havin g now set forth the object and nature of my invention and a form of construction embodying the principles thereof, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent of the United States, is-
