To @ZZ whom t may concern: t

Be it known that I, JOHN HARVEY CALD- WELL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful'lmprovements in Washing-Machines; and I `do hereby 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 appertains to make and use the sanne.y

Myinvention relates to improvements in washing machines of that class which employ a yielding bed in connection with a reciprocating rubber; and the objects of the present improvements, are, irslt,to provide an improved construction-by whichthe fabrics can be Washed and cleansed near they surface of the water contained in the tankv or suds receptacle, in order to keep the fabrics from being immersed in the sediment contained in the vWater at 'the bottom ofthe tank, and to secure the full benet of the detergent quality of the live soapsuds; secondly, to provide `nneans whereby the fabrics areheld firmly against the rubbing appliances to secure the best action on the fabrics withoutr injuring the same; thirdly, to provide means whereby.

the fabrics are raised and separated after the rubber acts thereon in order that the water` may pass through and saturate the fabricsv before the next stroke ofthe rubber;. and finally, to simplify and cheapen the construction, render it eflicient in operation, and durable in service.

With these ends in view, my invention consists in the combination with a suds receptacle or tank, and a bedhu ng or suspended therein, of a rubber consisting of. rollers hung in groups from yielding hangers'which arecon- .nected together for simultaneous operation.

My vinvention further consists in the construction of the rubber, and the means for suspendingy and guidingthe same within the tank, comprising a series of guides arranged Y arm, working in a slot, with a driving or power mechanism, rollers arranged in pairs whlch are journaled in a pair of yielding or Vspring hangers, which have arms fastened to the carrying frame o1l bail, and said arms extended to engage with the guides on the lid or top, whereby the hangers are moved back and forth with thecarrying frame o/r bail and engage with the guides, in order to sustain the rubber in operative relation to the bed.

My invention further consists in the combination with a suds box or tank, a rubber operating therein, and a bed suspended within the tank, of a series of spring lifters, supported by said bed at suitable intervals thereon, and arranged to be depressed by the action of the rubber as it is reciprocated over the'bed, said lifters being preferably made of spring metal and yieldingly held on the rubber-bed, to lift or raise themselves above the bed as the rollers pass, to lift and separate the fabrics and insure the circulation of the water through the fabrics, in orderto saturate the same; and the invention further consists in the novel combination of devices, and the peculiar construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to more, readily understand myinvention, I have illustrated the predicated by the dotted line :1c-@cof Fig. 1,look' ing-down upon the rubber and the bed, and showing the position of the guides which sus-` pend the rubber within the suds tank and enf ablev it to have the proper reciprocating movement therein. Fig. 3 is adetail perspective `viewof the reciprocating rubber detached from the suds tank. Fig. 4 is a like view of the rubber-bed, showing the yielding clotheslifters thereon.l f

Like letters of reference denote corresponding parts in all the figures of the drawings,

referringto which- A designates the suds tank of my improved washing machine. In the practical construc- `tion of this suds tank, I make it out of metal,

or of part wood and part metal, and to enable IOO a heating apparatus to be placed beneath the tank, for the purpose of keeping the water therein up to the desired temperature, but the heater may be dispensed with, if desired. Any suitable form of heater may be used in connection with the suds tank, although in Fig. l of the drawings I have indicated an oil stove or furnace for heating the water in the tank. The suds tank is substantially rectangular in outline, and it is supported at the proper elevation on the legs or standards, ct.

Vithin the suds tank, A, is suspended theu rubberbed,'B, which is shown as consisting,r of a flat piece of wood or metal. This rubber bed is proportioned to iit snugly in the sudstank, and it is suspended and sustained therein, at a suitable distance above the bottom ot' the tank, by means of the yielding hangers, C, C. These hangers may be of any suitable form, but in the drawings I have shown them as consisting of coiled springs attached to the corners of the bed, B, and to the ends of the sudstank, A. 'lhe yielding bed is provided with rows of perforations, b', which extend transversely across the bed, and which rows are spaced at suitable intervals from each other along the bed in the direction 0f its length; and said bed, B, of the machine is further provided with a series of grooves or channels, b, b, which likewise extend transversely across the bed, in the upper surface thereof, and are spaced at suitable intervals from each other. These channels or grooves are designed to receive the spring lifters, D, D, which are provided on the bed for the purpose of raising up the fabrics or clothes thereon after the rollers of the rubber have passed over the fabrics and the litters, so that the fabrics are raised and separated for the water to pass through and to saturate them be fore the next stroke of the rubber. I prefer to make these lifters, D, from a single piece of .rod or wire metal, and this metal is bent to provide the straight cross bar, d, the arms, cl', d', which are reversed or bent upon themselves, and the lateral prongs, d' The reversed br bent arms, d', extend at right angles to the straight bar, d, and the lifter is applied tothe bed, B, by dtting the bar, d, in the groove or channel therein, and by adjusting the arms, d,againsttheside edgesofthe bed,theprongs`, d, fitting underneath the bed, to receive the screws or nails by which the lifter is fastened to the bed. It will be noted that the reversed or bent arms, d' impart to thelifter a certain degree of elasticity or resiliency, and when the lifter is properly applied to the bed, the arms, d', d', operate to normally th row or elevate the cross bar d above the surface ot' the bed. The lifters are connected to the bed, B, to bring the bars, d, immediately over the grooves or channels, b, and when the rollers of the rubber operate upon the fabrics in passing over the grooves orchannels, the bars, d, of the litters are forced or depressed into these grooves or channels. As soon as the rollers pass one of the litters, the arms, d',

operate to raise the bar, d, and the fabrics on the bed immediately over the lifter-bar are thus' raised up, partly above the bed, so that the water can pass through the fabrics, to thoroughly saturate them.

I will now proceed to a detailed description of my improved rubber, and to the means for suspending and guiding the same Within the suds-tank, A. The rubber consists of a carrying frame or bail, E, the rollers, F, F, G, G, arranged in pairs or groups, and the hangers I-I, Il', grouped in pairs at the ends of each pair of rollers, said hangers being connected with the carrying frame or bail and with the guides, I, J, the latter being attached to the under side of the lid or cover, K, of the suds tank. This lid or cover may be hinged, or otherwise connected, at one edge or end to one of the Walls of the suds-tank, to enable the cover to be raised for the purpose of introducing the fabrics into the tank or 'rece`ptacle, A; and said lid or cover is provided with a longitudinal slot, 7c, through which projects an arm, e. This arm, e, is rigid with the carrying frame or bail, E, and the upper end of said arm is connected with a suitable operating mechanism by which the bail or frame, E, and the rollers attached to the yokes or hangers, H,H may be reciprocated. This driving mechanism may be of any suitable form or construction, such for example as a lever or a crank, but in thedrawings I have shown, as one embodiment of the driving mechanism, a shaft L, jonrnaled in suitable bearings on the top or lid of the tank, A, and provided with a cran-k, Z, to which is connected a pitrnan, Z', which pitman is in turn connected with the arm, e, whereby the bail and the rubber may be reciprocated.

Referring now more particularly to Figs. 1, 2 and 3, which illustrate the consti-notion of the rubber in detail, the carrying frame or bail, E, is made substantially rectangular in outline, and of metallic rods or wires of such strength as to stand the strain in practical operation. I have shown the rubber as provided with two pairs of rollers, one pair of which is designated by the letters, F, F, and the other pair by the letters, G, G; and each of these pairs ot' rollers is supported by two yokes or hangers H, H. Each yoke or hanger is preferably made from Wire bent to the appropriate form to provide the diverging prongs, h, h, and the double wire arm, 7L', which extends at right angles to thelength of the prongs, 72, h, to enable the arm h', to be attached to the bail or frame, E, and to be formed with a loop, h",which tits or takes over and around the longitudinal guide wire on the bottom of the lid or cover, K. i The rollers forming the pair are provided with trunnions, in, which are journaled in the eyes or loops on the ends `of the hanger prongs, to enable the rollers to have free rotation in the hangers when the rollers are pressed down upon the fabrics, in `order to rub and press the same. .By constructing the hangers or ZOO IIO

` or frame and the rollers in an operative posi-` tion on the lid or cover, K, of the tank A.

It will be noted that the arms, h', h of the pairs of hangers for each pair of rollers extend inwardly, across and over the bail, E, so as to be connected to the guides or rods, I, J, on thek lid, K, and this connection between the hangers and the guides or rods is made by looping the ends of the arm, h', around the rods, I, J, to permit the hangers to slide back and forth on the rods. The hangers may be fastened in any suitable way to the bail or frame, E, and the guides or rods, T, J, are fastened at their ends to the lid or cover, K, by means of screws, fi, or other fastenings, the middle part of the rods, I, J,v.being straight and a'rranged a short distance below the under face ofthecover, K, to enable the looped I ends of the hangers to have the proper movement or play on the rods I, J.

Although I have described in detail the par.- ticular form of guide rods, and the manner of connecting the hangers thereto, and have also described that the rubber consists of two pairs of rollers and their appropriate hangers, yet I would have it understood that I do not strictly limit myself to this particular form of guide rods, and ,connection of the hangers therewith, nor to the particular number of rollers which may be used in the construction of the rubber, because I am aware these details canvbe modified without departing from the spirit of my invention.

By the employment of hangers to yieldingly sustain the group of rollers, and the yieldingly suspended bed, C, I am vable to provide a clothes cleaning mechanism which will have its operative parts brought into close intimate contact with the fabrics to be cleansed, and which at the same time will yield vto accommodate itself to a bunched group so as to avoid wear thereon or of tearing of the fabrics. As the rubber is' reciprocated, the rollers press and squeeze the fabrics-- in order to eliminate the dirt therefrom, and the spring lifters, D, operate to raise up and open the fabrics after the rollers pass over them, so that the Water is free` to pass through and saturate the fabrics,thercby contributing to theeiciencyand rapidity of the operation of washing the clothes. rThe sediment and dirt eliminated from, the fabrics settle at Vthe bottom of the vtank, A, and by suspending the bed some distance above the bottom of the tank,I am able n to operate on the fabrics in the water n ear the surface and to utilize the live or most efficient part of the soap suds in the tank, A.

Having thus fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
