-W' ASHINQ-MACHIN E.

Specification of Letters Patent.

Application filed March 13, 1916. Serial No. 88,802. I

To all whom it may concern:

Be it lmown that I, OLIVER B. WooDRow, a citizen of the United States, and resident of Newton, in the county of Jasper and State of Iowa, have invented a certain new and useful Washing-Machine, of which the following is a specification.

The object of my invention is to provide a washing machine of simple, durable and inexpensive construction.

A further object is to provide such a washing machine having a supporting frame with a tub pivotally mounted thereon and capable of tilting movement, the tub being pivoted at such points that when in proper position on the bench it tends to remain in such position, and yet so that the tub can be tilted by lifting only a small part of the weight thereof.

A further object is to provide in connection with such a support and tub, an agitator and a gearing mechanism designed to be connected with a source of power so arranged that the tub can be tilted without interfering with the gearing mechanism.'

A further object is to provide in such a machine a compactly arranged gearing mechanism for operating the agitator.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation of a washing machine embodying my invention.

Fig. 2 shows a top or plan view of the same.

Fig. 3 shows a rear elevation of the same.

Fig. 4 shows a detail, sectional view, taken on the line 44 of Fig. 3, and

Fig. 5 shows a detail, sectional view of part of the gearing.

In the accompanying drawings I have used 'the reference numeral 10 to indicate generally a supporting frame. Above the frame 10 is a washing machine tub 11 pivoted at its sides near its lower portion at 12 and 13, to upwardly extending frame members. The tub is so pivoted that a considerable portion thereof projects beyond the frame 10, as clearly shown in Figs. 1 and 2, and yet so that the greater weight of the tub is above the frame. Thus the center of the tub rests over the frame,

The tub 11 is' provided with an ordinar hinged cover 14, in which is an agitator sha 15. Above the cover 14 is a gear casing 16 in which is a pinion 17 on the shaft 15.

Centrally pivoted on a bracket 18 on the side of the tub away from the frame 10 is a lever 19. Pivoted to the upper end of the lever 19 above the level of the tub is a rack bar 20 having teeth meshing with the teeth of the pinion 17.

Patented Aug. 13, 191 s. i

The bottom of the tub 11 is provided with ashort spout 21 on the side away from the frame 10, which spoutmay be closed by any suitable closure device 22.

Secured to the bottom of the tub on'the sidethereof which is above the frame, is a catch member 23. Rotatably mounted on the frame adjacent to the catch member 23 is a coacting catch member 24having a corrugated head 25. The corrugated head 25 may be grasped and rotated for bringing the catch member 24 to position for engaging the catch member 23, forholding the tub against tipping, or may be rotated to disengage the catch member 23 to permit the tub to be tilted.

Suitably mounted on the frame is a motor 26 or other prime mover, having a shaft-27 on which is a gear 28. A power shaft 29 is mounted on the' frame parallel with the motor shaft and has near one end a gear 30 in mesh with the gear 28 on the motor shaft.

Suitably mounted on the frame is a counter shaft 31 on which is a gear 32 in mesh with the gear 33 on the power shaft. On the counter. shaft 31 substantially in the same vertical plane with the lever 19, is a crank wheel 34 rotatably but nonslidably mounted. A pitman 35 is pivoted to the lower end of the lever 19 and to a crank pin 36 arranged 0% center on the crank wheel 34 Slidably but nonrotatably mounted on the shaft 31 is a clutch 40 adapted to coact with the clutch member 41 formed on the crank wheel 34. Pivotally mounted on the frame is a lever 42 having a downwardly extending end secured to a rod 43. The rod 43 extends horizontally through a suitable guide 44 to position near the clutch 40. The end of the rod 43 near the clutch 40 has a right-angled extension 45 having at its end forked arms 46 received in opposite sides of a suitable groove 47 of the clutch 40. By manipulating the lever 42 the clutch 40 can be thrown into and out of engagement with the clutch 41 on the crank wheel 34 for open.

' mecha- It will be noted that the gea on the nism herein described is moun I frame below the level of the 'upper surface thereof and below that portion of the tub 11 which stands above the frame. The lever 42 has a handle portion projecting upwardly beyond the frame to position convenientof access to the operator of the machine.

The gearing mechanism is of simple and compact arrangement, and is so geared down that a high speed .motor will impart rotary.

pail or another tub or the sewer opening located at the side of the frame where the frame will not interfere with such pail or the like.

It will be noted that the mechanism for operating the agitator shaft 15 is so arranged that the tilting of the tub does not in any way interfere with said operating means.

. emme I realize that changes may be made in the construction and arrangement of the various parts of my improved machine, as herein described, and it is my intention to cover by this application any such changes which 'may be reasonably included within the scope of the following claim.

I claim as my invention: In a device of the class described, a frame,

a tub pivoted on an axial line substantially adapted to drive said driven mechanism, an outwardly extending bracket fixed to the tub below said rod, a walking beam pivoted to said bracket and having its upper end operatively connected with said reciprocating rod, an operating mechanim dlsposed on the frame in such position as to counterbalance the weight of the overhanging portion of thetub, a pitman operatively connected with the operating means and the lower end of the walkin beam, and means for locking the tub in its horizontal position from pivotal movement;
