' WASHINGI-IIVIIACHINE.

SPECIFICATION forming part of Letters Patent N 0. 725,260, dated April 14, 1903. Application filed October 29, 1902. Serial No. 129,318. (No model) To (11 whom it may concern.-

Be it known that 1, MICHAEL J. KREMER, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented a new and useful Washing-Machine, of which the followingis a specification.

The invention relates to improvements in washing-machines.

The object of the present invention is to improve the construction of washingmachines and to provide a simple, inexpensive, and efficient one adapted to be readily operated and capable of enabling clothes and other fabrics to be rapidly and thoroughly washed. p

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a vertical sectional view of a washing-machine construct.- ed in accordance with thisinvention. Fig. 2 is a similar view taken at right angles to Fig. 1. Fig. 3 is a detail perspective view of one of the sectional boxes or bearings, the parts being separated to show the interior construction. Fig. 4 is an enlarged detail view illustrating the construction of the joint of the bottom of the washing-machine body.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a washing-machine body or tub mounted in a suitable frame or stand 2 and provided with a curved bottom 3 and having sides 4:, forming continuations of the bottom and converging upward slightly, as clearly shown in Fig. 2. The curved bottom is composed of transverse sections or pieces, provided in their adjacent edges with grooves 3, approximately semicircular in cross-section and receiving round rods 3 which overlap the joints and which are adaptedto swell in the openings, whereby a water-tight joint is effected. The sides 4 and the curved bottom are provided with a suitable rubbingsurface, preferably formed by corrugating or flu-ting their inner faces. The ends of the washing-machine body conform to the configuration of the sides and bottom and are suitably secured to the same. The washingmachine body is provided at the top with a hinged lid or cover 5, havingslots 6, through which extend stems 7 of clothes-engaging devices8. Theclothes-engagingdevices,which are approximately cylindrical, are provided with annular grooves or corrugations, forming ribs, which are adapted to engage the clothes and other fabrics to be washed when the devices 8 are moved vertically and swung horizontally, as hereinafter explained. The stems 7 are provided with longitudinal openings or slots 9, which receive antifrictionrollers 10, forming pivots for the stems and adapted to fulcrum the same. The antifriction-rollers are mounted on pivot-bolts 11 or other suitable devices, which are supported in perforated cars 12 of plates 13, secured to the upper face of the lid or cover and provided with slots or openings 14, registering with the openings of the lid or cover. The openings of the stems extend to the upper ends thereof and receive sectional boxes or bearings. The boxes or bearings are composed of sections 15 and 16, provided at their tops with inner transverse grooves 17, forming bearingopenings for cranks 19 of a shaft 20. The sections 15 and 16 are provided at their outer faces with longitudinal side flanges 21, forming grooves for the reception of the side portions of the stems 7, and these grooves also receive the sides of a resilient lining 22, located within the opening or slot 9 of the stem 7 and adapted to receive the wear. The lining 22 is preferably made of brass and approximately U -shaped, and the resiliency thereof holds it against lateral displacement, and it is held against longitudinal movement by the fastening device 23, which connects the sections of the boxes or bearings and which secures the same to the stems. The fastening device 23 passes through perforations of the sides of the stem 7 and is arranged in slots or openings 24 of the sections 15 and 16, which are also interlocked by means of lugs 25, formed integral with the section 10 "tated.

and fitting in recesses 26 of the section 15. The lower portions of the sections 16 are recessed or cut away, as shown at 16, and the lugs are arranged at the top and bottom of this recessed or cut-away portion. The crankshaft 20 isprovided'-With oppositely-disposed crank-bends arranged in the bearing-openings of the boxes or bearings and adapted to reciprocate the stems when the shaft is ro- The stems are slidably fulcrumed on the top of the washingmachine body by means of the pivots formed by the antifriction devices, and when the shaft is rotated the clothes-engaging devices will be raised and lowered and will be swung horizontally, thereby thoroughly rubbing the clothes against the bottom and sides of the body and enabling the fabrics to be rapidly and thoroughlycleaned'. Thecrank-sbaftisprovided at one end with a balance-wheel, and itis journaled in suitable bearings 27 of standards 28, which are mounted on the lid or cover of the washing-machine body at the outer sides of the slots or openings of the same. The balance-Wheel 29 is provided with a crank-handle and is adapted to be rotated to operate the washing-machine.

What is claimed is- 1. A washing-machine comprising a body, clothes-engaging devices provided with stems havinglongitudinal slots, fulcruming devices mounted on the body and arranged in the slots of the stems, bearings secured in the slots of the stems, linings arranged in the slots and having their ends interposed between the bearings and the sides of the stems, and a crank-shaft having cranks arranged in the bearings, substantially as described.

2. A washing-machine comprising a body, clothes engaging devices having slotted stems, sectional bearing-boxes arranged in the slots of the stems and provided at their sides with flanges forming exterior grooves, linings arranged in the slots and having their ends fitted in the grooves, fuleruming devices mounted on the body and arranged within the slots of the stems, and a crank-shaft having cranks arranged in the bearings substantially as described.

3. A washing-machine comprising a body, clothes-engaging devices provided with stems having slots, bearings or boxes composed of sections arranged in the slots, one of the sections of each box being provided with opposite recesses and the other having lugs fitted in the recesses, fastening devices securing the hearings or boxes in the slots, and a crankshaft having cranksarranged in the bearings or boxes, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
