Application mea Jury 19, lai?. serial No. 181.621.

To all whom t may concern Be it known that I, WILLI'AM H. Voss, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification.

This invention relates to washing machines, and more particularly to such .machine in which the lid may be swung back, or removed, without disconnecting the -con-A necting rod from the driving journals.

With the old form of connecting rod, it is necessary before raising the lid of the tub to stop and go through the laborious operation 'of disconnecting or removing the connecting rod from the driving mechanism for the reason that in swinging back the lid (when the same is hinged) the distance between the points of connection of the driving mechanismwith the two ends of the connecting rod increases, and unless the con* necting rod were disconnected at one or both ends the full swing of the lid could not be obtained. In instances where the lid is not hinged, but removed bodily, this need for disconnecting the connecting rod would be even greater. Th's disconnection or removal ofthe connecting rod involves considerable time, labor, and veXation, allof which tends to decrease the efliciency and ease of operation of the machine. With the new form which I have invented, other possiblev difficulties are completely overcome, and the swinging back or complete removal of the lid made exertion or time necessary other than the mere operation of a simple the foregoing and l latch.

Among the objects of this invention, therefore, is to provide such form of washing machine that by a single simple operation of the operators hand, :the connecting when the lid Vis swung back on its hinges;

rod may be instantly converted into such condition that its length will be automatically increased as the lidis swung back or removed; further to effect the automatic locking ofy the parts of the connecting rod into a rigid unitary structure when the lid is returned to its operative position; further toform such rod of two telescoping parts y that they may be completely separated to entirely remove the A should it be desired lid, or merely extended without separation necting rod further to provide a novel form of lock for such rod which non-extensible position when in operative position, and which by a simple touch of the operators linger will permit the extension of the rod to take place when desired; further to provide such rod that will permit the removal or swinging back of the lid without disconnecting one or both ends of the rod from the journals which connect therewith; further to provide such combina-v tion of connecting rod with washing machine mechanism as to make possible a quick and easy separation as well as connection of the mechanism on the top of the tub With that below the tub; and further .to provide such combination, construction and arrangementsof parts as will result in a more simple, economical, and efficacious washing machine than herefore known.

Further objects and advantages will appear as the following description proceeds, and while I have illustrated a preferred embodiment of my invention, I desire it understood that the same is susceptible of modiiication and change without departing from the spirit ofmy invention. In, the drawings:

Figure 1 is a side elevation of a washL ing machine embodying my invention, and

. showing the lid in 'closed position'.

Fig. 4 Yis a view similar to Fig. 3, but showing the parts in distended position.

Fig. 5 is a side elevation of the upper portion of Fig. 4. v

Referring to the drawings:

Upon the tub l is a cover or' lid 2, which ,is provided with suitable means for locking it in operative position thereon. Secured to the top of the lid 2 is suitable dasher operating mechanism, which comprises gearing located within the housing 3, and opera'- tively connected with the dasher 4. This mechanism also comprises the crank arm 5, which is' journaled in suitable bearings secured to the top of the lid 2. Upon the free end of the crank arm 5 is a journal 6, which is journaledjin th upper end of the will hold the rod in rigid 1 connecting rod 7. Suitably journaled to the lower end of the connecting rod 7 is the journal 8 carried by the crank arm'9, which is -mounted upon the drive shaft 10, which drive shaft is driven by any suitable source of motive power, and which in the embodiment illustrated is mounted on the frame work beneath the tub.

The connecting rod 7 is composed of the rod portion 11 and the tubular portion 12, which rod telescopes within the tubular portion 12 as shown. Upon the upper end of the rod 11 is a casting 13 carrying the latch 14 by means of the pivot 15, and which latch is provided with the finger portion 16 and the catch 17. This latch14 is ivoted as shown within the slot 18 provi ed in the casting 13, which casting is suitably fastened by threads, rivets, or otherwise, as desired, to the end of the rod 11. On the lower end of the casting 13 is the shoulder 19, the function of which Will later appear. The tubular portion 12 has mounted upon its upper endby means of screw threads or other suitable connection, the transversely extending'v projection 20, the under face of which is beveled as at 21, this bevel being such that when the face 22 of the catch 17 is in engagement therewith, the relation between these surfaces will be such as to hold the telescoping parts firmly locked against separation. When the parts 11 and 12 are completely telescoped, the shoulder 19 will be in engagement with the upper end of the tubular portion 12, should this tubular portion extend through the projection 20, or in engagement with the upper end of the projection 20, should the tubular portion 12 not extend entirely therethrough; the particular arrangement of the structure inl this matter being a matter of choice. AUpon the lower end of the tubular portion':2f-12l is a suitable casting 28, vwhich maybesecured thereto' by means 0of threads,.andwhich will be locked 1n position by meansof the lock` nut 24a The journal 8 of the crank 9- before mentioned is journaledg'within ay suitable opening in this` casing23'and held therein by means of a cotter-key 25. The journal 6 of the crank arm 5 is-likewise mounted in an opening 1n the upper end of the casting 13., as shown in Figs.'1 and 2.

The operation of my improved washing machine is as follows: When the tub is in u se and the mechanism is in operative position, the connecting rod 7 'will be in position shown in Fig. 1, with the rod portion 11 completely telescoped Within the tubular portion 12 and the catch 17 of the latch 14 in engagement with the bevel surface 21 of the lateral projection 20. This engagement of the latch with the lateral projection securely holds the telescopingparts 11 and 12 of the connecting rod 7 .rigidly together, so

,c fhat motion from the crank arm 9 may be transmitted through the connecting rod 7 to the crank arm 5, and from thence throu h the dasher. operating mechanism to t e dasher within the tub, and the connecting rod will thus act as a unitary structure,"the saine as though no `telescoping parts had been provided. Should it be desired to open the tub and raise the lid thereof, this can be done without the labor and loss of time necessary in disconnecting one or both ends of the connecting4 rod from the journals of the

crank arms

5 and 9. This is accom'- plished by grasping the finger portion 16 of the latch 14:, and raising the same slightly so as to disengage the catch 17 from the bevel portion 21 of the projection 20. After these parts are disconnected, the lid 2 may be raised, and. in so doing the rod portionk 11 will be pulled out of the tubular portion 12 a distance necessary to accommodate the movement of the crank arm 5, which is carried by the mechanism mounted on the top of the lid 2, which crank arm during the opening of the lid is given a movement in the arc of a circle,lthe center of which would be on a line through the hinges of the lid. When the lid is open, the parts will be in the position shown in Fig. 2, where it will be noticed the rod portion 11 is withdrawn to a considerable distance from the tubular portion 12, but still not entirely removed therefrom. After the catch` 17 is disengaged from the lateral 'projection 20 the latch 14 may be dropped, and it will occupy the position shown in Figs. v2 and 4. When it is desired, the lid may-be closed and such closing movement will return the rod 11 within the tubular portion 12, and when the lid is completely closed, the position of the rod 11 and tubular portion 12 will be such that they will be completely telescoped, andI as the catch 17 passes over the projection 20, the weight of the latch 14-will by gravity cause the catch 17 to automatically engage the bevel portion under theprojection 20,

11o thus securelylocking the telescoping parts from further movement with relation to each other, after which the connecting rod will operate as a unitary structure to drive the dasher operating mechanism. Y

It will thus 'be seen that Ihave provided t a mechanism in which the lid of the washing -machine may be raised or opened without any further work, in so far as theconnecting rod is concerned, than merely raising the4 latch 14 from engagement with the projection 20, which as .shown above, permits the rod portion 11 to be withdrawn th'e necessary distance from the tubular portion 12. Should it be desired to entirely remove the lid 2, together with its attached mechanism, this can be done for the reason that the rod portion 11 continues of the same size to its lower end, thus'permittin it to' be entirely withdrawn froinx he tuiiularf-portion 12 if desired. My improved structure results in considerable saving of time for the reason that in opening or removing the lid it is not necessary to disconnect either end of the connecting rod from the crank arm journals as has heretofore beenv necessary in washing machines.
