To v1f/ZZ whom, it may concern: -I

le it known that LJESSE W.SUNDERLA.ND,

a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illi- 5 nois,'have invented a new and useful Improvem ent in'lVashing-ltlachines, of which Vthe fol-l lowing is a specification.

My invention relates to an improvement in washing-machines of the class in which a' ro-4 tating cylinder having perforated `walls is .caused to rotate within a stationary cylinder and' contains traveling disks, nsually perforated, which are caused automatically tom'ove toward and'away from each other to ede'ct a contained in the cylinderr.- l

In an apparatus loli this' character of .the

. kind to which my invention-more particularly relates the rotatable'cylinderis caused to turn thereupon to turn in thereverse direction, said rotation andV reversal being edected throughA ,ya belt-shifting mechanism on the pulleys, .and it has been the practice to cause the rotation of the cylinders in the opposite directions, respectively, to produce thehlovementof the travelingdisks within the cylinder.

My object is to improve washinglnachines of this `character in general, andparticularly 3c to-cause the movement of the traveling disks 'to be' in a measure independent'of'the rotation of .the cylinder, while at the same time causing both operations to-be accomplished from thesame power controlled by the'belt- 35-shifter. V l L ,In the drawings, Figure lis a planscctional view on the line 2 2-ofjFig. 2 and viewed in 'u thedirection ofthe arro'w,.showingithe gen- I' eral construction of my device; Fig. 2, a view chine; fFg. 3, a vertical transverse section taken on line'3 3 ot Figuilnnd viewed in the direction of the arrow, parts being brokenVv .away to illustrate details of the construction fof two similar roller-hearing devicesemployed thorough washing and cleansing of the clothes in one direction a certain n'umberof times and" in end elevation, taken at the head ofthe mawhich would otherwisegbe hidden from viewj Fig. 4, a broken end .elevatiompartly in secstion, the section heingtaken on' line 4 4 ofljf `Fig. landqviewed" in' the direction .Q fthe alf-j ger-rods Whichcarry the traveling disk-s witl1 5 5 in the cylinder; and Fig. 8, an enlarged'sectional view of a portion of the inner cylinder,

A represents the' outer cylinder, which 'is 6o .supported on legs A. 1

The-heads B are provided with central perforations t and formed with central inner recesses t', about the perforations t, and within which are supported nests of roller-bear- 65. -ings C. v v

D is an inner or washing cylinder comprising end spiders s, having central outward-'projecting trunnionss', which extend into the recesses #and carry the nests or roller-.bearings 7o` C.- The walls of the inner 'cylinder D comprise perforatedv longitudinally-extending staves E, held together at theiredges bylongitudinally-arranged brace-rods E'. The brace'- rods E are in the form of half tubes, as indi- 75 cated in Fig. 5, provided at intervals with solid lugs E2, containing threaded sockets r. The Y lug portions E2 ot'- the brace-rods E presentl ,cesses the spidersare providediwi-th periphgo "eral cog-teeth s2.

Within the cylinder D 'are supported`the l spidersE F,ea ch carrying-a perforated platep.. The `spiders EF' have the circumferential configuration ofv the cylinder D and are 93.

.adapted'to slide in the latter. The spider F at itscenter fits over the inner end cfa plnngerlrod G, and the spider F receives centrally the inner endof a plunger-rod G.- The rods G G areeach provided on onetface with a rack roo o', which is shown in the drawings as presenting'the-ou'ter -.edge of each tooth within the circumferential 'area vof the rod. AThe rods.. G G' extend-...through the trunnions s? and through the central apertures tn of the heads i3 B of the outer cylinder. The spiders F F', though held to and carrying the plunger-rods G G', `are rotatable thereon, this being accomplished by providingan annular groove 0' near the end ot'4 each plunger-rod, which groove is engaged by set-screws o2 passing through tlie'hubs of the spiders. The heads l; B at opposite ends of the cylinder A carry, bolted thereto, supplemental heads I-I II', and lpivotally mounted upon the head H is hydraulicjack mechanism I, presently described. Tie-rods K extend from one supplemental head H tothe other supplemental head ll", as illustrated in Fig. 1. Y

Supported in a suitable bracket L at one side of the head end'of the machine and extending to a corresponding bracket L at the foot end of the machine, is a horizontal shaft made of two independent sections M M.

Loosely surrounding the shaft-section M is a hollow shaft or sleeve M2. The shaft-section Y M is provided at itsouter end with a.' worm n and cn the outer end portion of the sleeve M* is a worm m.. \At its outer end the shaftsecton M is provided beyond-the bracket L with a worm m. Onthe sleeve M2, in the position shown, is a pinion N, which meshes with a pinion N', 'journaled on the bracket L, andthe pinion N extends at its periphery througha slot or opening in the outer casing A, and in turnmeshes with the cogs sion the spider s at the head of the machine. The shaft-section M4 carries, adjacent to` the bracket L a pinion N, which meshes with a Apinion N3, which in turn meshes with a pinion N4. The 'pinions N3 N are journaled upon the sides of the bracket L', andthe pinion N4-extends at its periphery through an opening-.in the outer cylinder A andmeshes with the cogs $2.011 the spider s at the foot end of the cylinder D. The sleeve M2 at its Vss p formed on thehead B, andillnstratedin Fig.

inner end carries a belt-pulley@ and the shaft-section M near its inner end carries a belt-pulley O Between 'the belt-pulleys O .O and covering the joints of the shaft-seetionsM' M is a pulley O", keyed to the shaftsection M'. Extending from the bracket L- to a supplemental bracket L, w ich forms one of the bearings of the shaft-se tions M,i's a be1t-shiftiug arm vP, having-the aperture l for the belt, and also the' socketedr end l',-to which 'is secured one; end -of 'a lever l. The

aperture! should be of a length approximating the width of the pulley 0', and thedrivebelt employed should be of a width approxi-4 mating vthe length of said apertures The' lever I hasjthe Yeionga'ted'slot Za and handle 2; .A worm-gear Q, jonrnaled on an armof the bracket Lqto mesh with the worm n on Vthe shaft-section MQ has'the.1eceentricpin Q., which enters the' elongated slotl? in the lever worm-wheeiR, mounted upon a shaft'R',-extending'across the head of the cylinder and terminating at its opposite end'l in bearings The worm mls adapted to meshv with a,

4. Between the said bearings at the head B the shaft R carries a pinion S,said pinion meshing with the teeth o on the plunger-rod G. The shaft R is so mounted in its bearings on the head 'B that it may vibrate to alimited-extent at its outer end .where it carries the worm-wheel R. Near its. outerl end the' shaft R' isjournaled in a bearing R?, sup# downward at its free end and disengages the worm-gear R from the worm m. At the '0p- -posite end of the machine the same construe-' tion is presented--that is tosay, wi'th the wormm. there meshes the worm-gear R, (see Fig. 3,) the shaft Rf which carries a pinion corresponding with the pinion S, which enadjacent 'head B of the cylinder in a manner to permit vthe shaft to swing in its .bearing and'carry thefworm-gear R intov andont of 'gages the-teeth on the plunger-rod G". The shaft R4 is jonrnaled in the bearing on the Ilo-0 engagement with the worm 'm'.` The shaft R4 is journaled adjacent to the worm-gear Riina bearing-collar kien, the upper end 'of ar'od.

k,f wl1ich at its lowJer end is pivotedupon a' pin k7 on a disk k. The disk is on the endof,

a rock-shaftk, journaled. in a bearing on one of thelegs of the machine, and carries a pin k7, eccentric withrelati'on to said shaft. Ex'- 'tending between'and pivotaliy'connected at opposite ends tothe ins lc k7 on therespective disks kk is a ro 10?, whereby. movement of the shaft k to raisfe or lower the worm-gear R is -Lm-parted to the shaft k and attendant parts, whereby the worm-gearR is thrown into and ont of' mesh with the worm m at the same time that the worm-gearis thrown into and out o'ffmesh withthe worm m. I

The hydraulic-jack mechanism comprises'a casing I, having a smooth inner.' face conform-v ing to the outer face of 'the' supplemental head H, The casing I is pivotally mounted at one end upon-an extension 4of one of the tie-bars K. It may swing on said tie-bar-between ver'- tical land horizontal positions,` and at its free .end it is formed into a hook I', whereby whenswnng tethejhoriwutal 4position it engages and 'is'held rigidly-'in place yby thetie-bsr'K on the .opposite side ofthe machine. "In th'e .casing I, is a chamber i, containing a; piston i. In the, casing at :opposite sides of the said chamber are two pump-cylinders t" in' which 'work pistons upon'the ends of piston-reds i' a?, at their outer ends connected witlia pumplever. I', which is pil'voted upon. the casing belas tween the pistol-rods-i". Extending from J the cylinders '1? to theend of the chamber 'i posed in the branches of the said pipe are check-valves 116, which permit water to pass freely through them to the cylinders, but prevent its retrogression. In thepassages 4, beatween the pump-cylinders and4 chamber i, are check-valves '512,'which prevent retrogress'ion of water from the chamber to the cylinders under the suction action of the pump-pistons when water is drawnin-throngh, the check" valves i6. As valves for this purpose are provided in ail pumps or hydraulic jacks, it` is thought to be uunecessaryin the present connection to illustrate them by special view. In the end of .the chamber il is an outlet-port 27, which communicates with a pipe is, which extends therefrom throlfi-gh the adjacent head B tothe interior of the cylinder A. Interposed in the pipe is is a valve '119, opened and closed by means of the hand-wheel'il". The sections of the pipes 'i5 c adjacent to the casing I- are of flexible material and offer no obf stacle to the swinging of theV casing between its vertical and horizontal positions.

- In the supplemental headH, registering on one side with the opening t and atits cppoJ site vside with the chamber' ,lwhen the casing I is inthe horizontal position, is an opening h of a diameter slightly exceeding the diame'i' ter of the' chamber; z'. v The pistoni is prevented from. covering-the ports in the .chambert by alpin il, carried by the piston', which strikes ,the linner fend of the chamber when the piston is moved inward. 'j It is to be understood that during the washing operation,

presently described, the hydraulic jack' is swung-to the vertical position to permit free reciprocation of the plunger-rod G, and when. the wringing operation :is to take place theplunger-rod is moved inward as far as it will go underthe action of the pinion'S, operated from the worm m, at. which time its outer end just clears the inner face'of the hydraulic jack when the latter isswnhg down tothe `horizontal A plane. Wat'enpumped into the chamber lagainst the piston 'i' forces; the 'lat-v Jterfoiitwardjinto the -op'eu'ing h and against -`the` outer end of. the plunger-rod G. The plunger-rod G moves through an opening g -in the lsupplemental headH, and when at the inward limit of its movement under the action of the pinion on the shaft R4 its outer end has passed inward through'the opening g to a po-v sition between the supplemental head H and adjacent head B. lleivoted upon `a bolt g', adjajcen't tothe opening g, are one or more' stopplates g2, which maybe swungjrcm aposiltiefn'out of the path of the outer end ofthe pl unger-rod-.G to a position across the path 4ol' thelatt'er., 'As hereinafter eX'plained,-.when v 65 v it is desired to perform'l thewringin-g opera'- tion the'pl ger-'rods G G- are movedv to their 'jinw'ard limits and oneor more of-the'plates s outer end-of the latter from the inner face of g3, are swung across the path ot. the plunger?v rod G', depending upon the. distance of the A #of the supplemental head I-I. This prevents the -said plunger-rod from being forced outward by -pressure from the rod G under the action ofthe hydraulic .j ack.

. The operation vis a follows: Thelhydraulic `7 5 -jack I beingturned on its pivot tothe vertical plane to' vuncover the opening'h' through the supplemental head H and the linternal traveling spidersF F being inthe'position indicated in Fig. 1, the-belt is shifted by hand 8o ,through the mediumof the lever l2 to overlap the pulley O, while still retaining its grip upon the pulley O2. Pressure is exerted upon one of thepedals 7a4 to move the .worm-gears'R R3 into meshV with the worms m, m', respectively. When the 'machineis started, the beltV rotates the pulleys O O2.. '.lhro'ughthe pulley O the' sleeve M2 and pinion N arerrot'atedto rotate the pinion N and turnfthe cylinder D on lits trunnions. The. rotation of the cylinder D through its engagement at the opposite end with the pinion N4 rotates the latter-,the pinion N3, and pinion N2 on the' shaft M The rotation of the pulley O4 produces rotation of the shaft M and itsworm-m. It' will be un- 95 derstood, therefore, that in the rotation of the pulleys O O'J the shaft M and its worm 'n and'the sleeveM2 and itsworm fm are allro- 'ta'tedimparting rotation to the cylinder D,

Athat of the shaft Mand sleeve M2. YDuring this rotation the 'worm m turns the'worm-gear [o5 R, -shaft R', andpinion S to cause the'plunger-'rod G and spder'E'tofmo'v'e inthe out ward direction; and the engagement ot the worm-gear R8 with the worm m causes it and` the shaft R4 toturn in thedirection for mov- 'r 1o ing the plunger-rodfand spider'F inthe outward. direction'. The plateg2, which inv Fig..1 is 'shown in the path of the. endof the- 'pl-unger-rodG, must be turned aside before thelcom'mencement of the operation.- r[,he ror1.5 tation of the shaft'M, and consequent turning .of its worm n,rotates the worm-wheel Q, and as the spiders F11", near -the opposite endsof the cylinder,4 the pinQ engages one len'd ofthe 'slot l"l o fthe lever 2 and pushes 12o lthe latter inv the direction to slidethe beltshifting bar P to the position wherein the belt engagesl the pulleys O2 and O. The en-L Agagement ot' the beltwith the pulleyO' projduces immediate reversal of said pulley and 125 theshaft M, whereby through the gears:NNs Nffsthe rotation of the cylinderD isreversed, an'd'through the engagement of the cylinder with the pinion N'-` a'nd throughA the-latter with the pinion N the rotation of the sleeve w3c M? and attendant 'parts is' reverf'ed. lTherefore' as soon as .the belt is shippedfrom. the'jpulley O to thepulley Of thev plungerl rode G G are moved- Ain the direction of eachother. When the spiders arrive at the' l 4 position indicated in Fig. 1, their movement iiO is again reversed and the operation will be continuous. '.lheinward and outward playof vdrive-belt, the water is withdrawn -from the cylinder A and the movement of themechauism described is'stopped when the spiders are both at their innermost position indicated spider F.

in Fig. l. As a preliminary to performing Vthe wringing operation, -th'e rock-shaft :.3 is

turned by'pressure upon one of the pedals 1" to lower thewormgears R Rs out ot'y ,engagement with the worm m, m', whereby move: ment of the plunger-rods G G' is'stoppe'd. One ormore stop-plates q2-are then swung across the path of the plunger-rod G.

The pump-lever 12 isthenoperated to force-water into the chamber 1 against the endof the piston i' and force the l'atter with the plungerrod G and spider Fin the direction of the By this means great pressureis exerted between the plates p, and the bar G is prevented from yielding by the stop plate or plates g2. Thepower-shaft frontiWhiehthe machine isoperated may be provided, as is"` common in all such cases, with fast andlos pulleys and belt-shipping mechanism, all of which it is'not thought necessary to illustrate.

1f desired, the belt-shipping mechanism may wringing'mechanism is brought into action.

lt is better, however, to permit the cylinderV 'D and disks ,1.2 to rotate, as described, while the wringing operation is being performed, because the motion tends to discharge the water by centrifugal force as it-issqueezed. out of the washed .articles by the .hydraulic jack. `fhen the wringing operation is complet'ed, the -workingof the pump is stopped.A

and the valve i. is opened by means of the .hand-wheel t1", causing the water in the chamber i to 'flow ont through the pipe i, intothe base ofthe cylinder A. The hydraulic jack is then swung tothe vertical plane, thestop plate or plates g2 are turned out of the way,` r and the rock-shaft L is'turne'd to cause. the; "worm-gears R R8 to-mesh withthe worms m mi.; This action causes the'plunger-rodsto- 4be moved in the direction of the ends of, the
