WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 762,851, dated June 14, 1904.

Application filed July 6, 1903. Serial No. 164,416- (No model.)

To all whom it 7720; concern.-

Be it known that we, BERT A. STOCKING and HIRAM MENDENHALL, residing at Audubon, in the county of Audubon and State of Iowa,

. haveinvented certain useful Improvements in vform a part of this specification.

This invention relates to a new and novel improvement in washing-machines.

The aimof our invention is to provide a washing-machine which shall be simple of construction, readily operated, and in which the Working effects are readily accessible; and our invention embodies certain other features more fully described hereinafter and finally pointed out in the claim.

In the accompanying drawings we have shown in Figure 1 a sectional view, with portions removed, of awashing-machine embodying our invention. Fig. 2 discloses an enlarged broken detail disclosing the knuckle used in securing the pitman and rack-bar. Fig. 3 shows a top View of the washing-ma- Fig. 4: discloses an enlarged broken detail illustrating the arrangement of the vertical supportingbar holding the'drive-shaft. Fig. 5 discloses a broken detached detail showing the method of securing the supporting-leg to the tub, while Fig. 6 shows the main bracket as used in our invention-in connection with the bands.

In carrying out the aim of our invention we employ an ordinary tub A, provided with the bottom 1 and the top 16, the top being provided with a door 15, having the hinges 15 secured to the reinforcement 16, as shown in Figs. 1 and 3. This top 16 is provided with a further reinforcement 16 upon the edge op-. posite the hinges 15, as shown. This door 15 has secured to it an ordinary handle 17 In order to prevent this tub from spreading apart, and, further, in order to provideatakeup we employ three wire strands, preferably of steel, (marked 2, 3, and 4:.) Each strand or wire member 2, 3, and 4 is provided with ahead f,

while its remaining end is threadec to IGCGIVG a suitable bur a, as shown more clearly in Fig. 6. These strands perform the function of bands for the tub to secure the same. Now should the tub remain out of use for a while, so that the sections composing the tub should contract, the loss may be taken up by means of these burs provided with bands to secure the tub.

In connection with our washing-machine we use a main bracket 5, in the form of a bar 5, as shown in Fig. 6, this bar being provided with six openings,- as shown in Fig. 1, through which the bars 2, 3, and 4 pass, as disclosed. Extending outward from the sides of this bar 5 are two half-rings 5, which may form an integral portion of said bar or be secured to the same, and these two ring-sections 5 serve as a holder in that we provide the pin 6, from which extends the pivotally-supported'hand-lever B, provided above with the operating-handle Z). This operating handlever is positioned between the two ring-sections 5, and near its lower end this lever is provided with a pin 3, adapted to work within the slot 4 of a rock-bar a, as disclosed in Fig. 1. This rock-bar is supported by means of the pin 6, held within the ring-sections 5. Below this rock-bar a has secured to it a head 7, into which threads the pitman 30, which is locked by means of the nut 31, as disclosed in Fig. 1.

Secured to the bottom of the tub is a ring or annulus 24:, provided with the transverse bar 25, this ring assisting in strengthening the bottom, being very nearly as large as the bottom. In Fig. 1 a sectional view of "this ring or annulus is shown. WVorking within this transverse bar 25 is the upper end of a suitable shaft 0, as shown in Fig. 4, which shaft is held within the vertical supportingbar 2'7, which bar below, by means of a bolt 40, is secured to the loop-bar 26, as shown in Fig. 1, so that this vertical supporting-bar is securely held. The suitable shaft 0 is provided with a bevel-gear 27, which gear meshes with a bevel-gear 29, mounted upon the suitable shaft 28, to which suitable shaft is'secured a belt-pulley 28" in case this machine should be run through belt transmission.

IOO

The suitable shaft 0 supports a horizontallydis posed balance-wheel 26, as clearly shown in Figs. 1 and 4c.

Secured to the bevel-gear 29, as disclosed in Fig. 1, is a pin 30, to which is secured the pitman 30, so that as the hand-leverB is operated the lower rock-bar a is actuated to reciprocate the pitman 30 to rotate the bevel-gear 29, actuating the suitable shaft 0 and its connected balance-wheel. By this means after the balance-wheel 26 has been set in motion the rotation of the same materially aids in insuring steadiness of the working effects and also facilitates the operation of the machine.

Secured to the lid 15 is a plate 19, and secured to this plate 19 is abracket 19, having a boss 20, this bracket being secured by suitable bolts 0.

Held between the brackets 19 and the plate 19 is a rack-wheel 20, which is secured to a shaft 0, (shown in Fig. 1,) the upper end of this shaft C rotating within the boss 20, as shown in Fig. 1. Thelower end of this shaft C is adapted to receive the nut 12, to which is also threaded the guide-bar 13, upon which slidably works the head 14:, provided with the usual pins 14.

Secured to a pin 8 of the hand-lever B is the pitman 8, which pitman is provided near its forward end, as shown in Figs. 1 and 2, with a plate 9, bent U-shaped and secured to the pitman 8. Referring to Fig. 2, we have shown the forward end of the pitman 8, and within the forward end of this plate 9 is held the pin 10, which is flattened and is provided with the operating-lever 10, as shown in Fig. 1, so that this flat pin 10 may be brought into a horizontal or vertical position by means of the lever 10.

Slidably held between the rack-wheel 20 and the bracket 19 upon one side is the rackbar 18. the rack-bar of which meshes with the rack-wheel 20, and this rack-bar is provided with a narrow slot 9, ending in an enlargement, as'shown in Fig. 2, the slot 9 being equal in width to the thickness one way of the pin 10, while the enlargement at the end of the slot 9 is of a size to snugly accommodate the flat pin 10 when in a vertical position, as disclosed in Fig. 2. By means of this U-shaped plate 9, the pin 10, and the slot 9 a knuckle is formed, by means of which the pitman 8 and rack-bar 18' may be detachably secured.

WV hen all the instrumentalities have been properly arranged, the operation of our washing-machine will be as follows: The lever 10 will be actuated to release the rack-bar 18 from the pitman 8, so that the lid 15 may be opened. The clothing, water, and the detergents are then placed in the tub, when the lid 15 is closed. The pitman and rack-bar are again connected when the machine is ready to be operated, which is accomplished in rocking theleverB backward and forward. After the machine has been set in motion the momentum acquired by the balance-wheel 26 materially adds to the steadiness of the machine as well as facilitates the operation of the same.

These washing-machines are made of various sizes and shapes. In order to support them, we provide a standard-holder comprising the member D, having an ear 23 above, as disclosed in Fig. 5, which car holds and supports the intermediate band 3, there being three such standard-holders, so that the intermediate band is supported at three points. The upper band 2 is supported but at one point by means of the main bracket 5. Below this member D is provided with a U- shaped plate 22, perforated so that the lower band 4 passes through perforations within the belt-plate 22. This plate 22 is so arranged that there will be a space sufficient to permit the insertion of the wedge shaft and of the supporting-standards 0. These standards 0 may also be perforated or have a portion cut away, permitting the insertion of the lower bands 4:, as shown in Fig. 5. To further secure these standards a, We employ a screw (Z, as shown in Fig. 5. By means of these standard-holders the lower and intermediate bands are supported in the manner set forth.

Having thus described our said invention, what we claim as new, and desire to secure by United States Letters Patent, is

In a washing-machine, the combination of the following instrumentalities, to wit: a topprovided tub, a hinged door secured to said top, a main bracket secured vertically to said tub, a half-ring extending from the lower end of said bracket, a hand-lever pivotally secured to said half-ring, a pin projecting from said hand-lever, a rock-bar also pivotally secured to said half-ring provided above with a slot within which is held said pin, a pitman eX- tending from the lower end of said rock-bar, a vertical shaft secured pendent, from the bottom of said tub, a bevel-gear secured to said shaft, a horizontal stub-shaft suitably secured below the bottom of said tub, a bevel-gear secured to said horizontal shaft meshing with 'said first-mentioned bevel-gear, said pitman being pivotally secured to said bevel-gear mounted upon said horizontal shaft, a bracket secured to said lid, a shaft projecting through said bracket and lid, into said tub, a rackwheel secured to said last-mentioned shaft, an agitator-head secured to said last-mentioned shaft, a pitman pivotally secured to said handlever, and a rock-bar meshing with said rackwheel, and adapted to be detachably secured to said last-mentioned pitman.
