SPECIFICATION forming' part of Letters Patent No. 674,470, dated May 21, 1901.

Applicationflled May 8, 1899. Serial No. 715,938. (No modelfx To all whom t may concer-n.-

Be it known that we, ZOUAVE S. RANDLE- MAN and MARTIN C. RANDLEMAN, citizens of the United States, residing at Carlisle, in the county of Warren and State of Iowa, have invented certain new and useful Improvements in Washing-Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- I pertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

The object of this invention is to provide improved means for washing clothing, blankets, carpets, and similar articles.

This invention relates to and is an improvement upon the machine illustrated and described in our application for Letters Patent of the United States, filed May 23, 1898, and serially numbered 681,536.

Our invention consists in the construction, arrangement, and combination of lelements hereinafter set forth, pointed out in our claims, and illustrated by the accompanying drawings, in which- Figure 1 is a side elevation of the complete machine. Fig. 2 is a side elevation of the complete machine opposite to Fig. 1. Fig. 3 is a plan of the machine,the cover being removed. Fig. 4 is a central vertical section transversely of the machine. Fig. 5 is a detail View illustrating the connection between a sprocket-wheel and shaft employed in our machine. Fig. 6 is a face view or elevation of one of the rubbing-disks detached from the machine.

In the construction of the machine as shown the numeral 10 designates a tub, to which a cover 11 is secured by hinges 12 13. The tub and cover combined form a receptacle or inclosure of cylindrical form, the heads of the cylinder forming the ends of the tub and cover and the shell of the cylinder forming the bottom of the tub and top of the cover. The ends of the tub and cover preferably are formed of Wood, and the bottom of the tub and top of the cover preferably are formed of sheet metal. Hooks 14 15 are pivotally connected at their upper ends to the ends of the cover 11, and when the machine'is closed depend through staples or eyes 16 17, projecting outwardly from the ends of the tub 10. The free extremities of the hooks 14 15 engage the staples 16 17 when the cover is raised and support said cover against further opening. Cleats 18 19 are Xed to the tub and cover, respectively, and carry the members of the hinges 12 13. Cleats 2O 21 are fixed to the tub and cover, respectively, on the side thereof opposite to the cleats 18 19, and a screw-eye 22 in the cleat 21 is ,engaged by a hook 23 on the cleat tolockthe cover to the tub. A knob 24 is mounted. in one end of the cover 11 and arranged for engagement by the hand of the operator to lift the cover when it is desiredv to open the machine. A Wringer stand or bracket 25 is fixed to and projects from the tub 10 adjacent the cleat 20, and the bottom of said stand is inclined downwardly toward the tub, ports 26 27 being formed in the cleat 2O to afford communication for the drainage of water from the wringer stand or bracket into the tub. A bearing-clip 28 is mounted on one end of the tub 10, and a shaft 29 is mounted for rotation in said clip and eX- tends through a metallic bushing 30 in said end of the tub. The shaft 29 is provided with a crank 31 on one end, and a disk 32 is mounted rigidly on the inner end of said shaft parallel with the ends of the tub. A grooved Wheel 33 is mounted rigidly on the shaft 29 within the bearing-clip 28 and is connected by a crossed rope belt 34 to a grooved wheel 35, mounted rigidly on one end portion of a countershaft 36, which countershaft is mounted for rotation in bearings fixed to the tub parallel with the shaft 29. A bearingclip 37 is mounted on the end of the tub 10 opposite to the bearing-clip 28, anda shaft 38 is mounted for rotation in said bearingclip 37 and extends through a metallic bushing 39 in said end of the tub in alinement with the shaft 29. A disk 40, corresponding in size to the disk 32, is mounted on the inner end portion of the shaft 38 and rigidly connected thereto. The shaft 38 is fiattened on one side, and a sprocket-wheel 41 is mounted on said shaft and connected by a sprocket-chain 42 to a sprocket-wheel 43, rigidly mounted on the end of the counter-shaft 36 opposite the grooved Wheel 35. The sprocket-wheel 41 is confined between the IOO bearing-clip 37 and the end of the tub on which said clip is mounted, and the bore of said wheel is formed with a projection fitting the flattened face of the shaft 38 in order that the shaft may he moved longitudinally through the sprocket-wheel and bearings'and be rotated by said sprocket-wheel. The shaft 38 is of such length that it may be moved longitudinally to adjust the disk 40 relative to the disk 32. Ahead 44 is formed on the outer end of the shaft 38 to limit and determine the inward movement of said shaft and the disk 40. A drainage-port 45 is formed in the lower marginal portion of the end of the tub adjacent the disk 40,and said port is closed when the machineisin operation by a plug 46. Leg-brackets 47 48 49 50 are mounted on the ends of the'tub lO and are arranged to receive legs 51 52 53 54, whereby the tub is supported, and a chain 55 connects the plug 46 to the upper portion of the leg 53. 'lhe rubbingdisks 32 40 are each formed of wood circular and of slightly-less diameter than the cylindrical inclosure formed of the tub and cover. Annular wire hands 56 57 are countersunk in the marginal'portions of the inner faces of the disks 32 40 and held by staples 58, driven in the disks. Annular wire bands 59 60 are mounted on the marginal portions of the outer faces of the disks 32 40, opposite the bands 56 57, and are secured thereto by staples 6l, driven in the disks. The annular wire bands 56 57 59 60 are provided rigidly to, connect and hold the parts of the wooden disksin the event that said disks are split unintentionally in use or composed of several pieces in their manufacture. Rubbing-cleats'62.are mounted radially on and fixed to the inner faces of the rubbing-disks 32 40.

When the machine is employed for washing fabrics, the tub is partially filled with water, the fabric articles are mounted in the tub between the rubbing-disks, and the disk 40 and shaft 38 are moved inwardly toward the disk 32 a distance sufficient to cause the disks to compress said articles between them. The cover ll then is closed and the machine operated by manual force applied to the crank 3l in the direction of the arrow in Fig. l. During the operation of the machine the disk 32 rotates in the direction of the arrow thereon, and the disk 40 rotates in the opposite direction, as indicated by the arrow thereon, thus setting up a rotary movement of the fabric articles between the disks, agitating the water in the tub, and thoroughly cleansing said articles. The rubbing-cleats 62 are triangular in cross-section, and in the travel of said cleats the water is engaged thereby and currents formed in the water across the tub, or, in other words, a thorough agitation of the water is established and maintained coincident with the rotary agitation of the fabric articles.

We claim as our inventionl. The washingmachine comprising the tub and cover conjunctively of cylindrical forni, the hearing-clip on the central portion of one end of the tub and centrally apertured, the metallic bushing mounted in a central aperture of one end of the tub in alinement with the aperture in the clip, a shaft mounted for rotation in the bushing and central aperture of the clip, which shaft is flattened on one side, a rubbing-disk rigidly mounted on the inner end portion of said shaft within the tub, a sprocket-wheel slidably mounted on said shaft between the hearing-clip and tub, a bearing-clip 28 mounted on the opposite end of the tub and centrally apertured in line with a central aperture in the adjacent end of the tub, a metallic bushing in the latter said aperture of the tub, a shaft 29 mounted for rotation in said latter clip and bushing and provided with a crank on its outer end portion, a rubbing-disk rigidly mounted on the inner end portion of the shaft 29, a grooved pulley on the shaft 29 between the tub and clip,a counter-shaft mounted for rotation and extending across the periphery of the tub, a grooved pulley on one end of the countershaft, a crossed belt connecting the grooved pulleys, a sprocket-wheel on the opposite end of the counter-shaft and a chain connecting the sprocket-wheels.

2. In a washingmachine, a rubbing-disk formed of Wood and of circular form, annular wire bands countersunk in the marginal p0rtions of the sides of said disk and stapled thereto, means for mounting said disk for rotation and rubbing-cleats mounted radially on one side of said disk, each of said rubbingcleats being of materially less length than the radius of the disk.
