WASHING-MACHINE.

Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed May 4, 1910. Serial No. 559,357.

' washing machines and its object is to provide a machine for the purpose so constructed as to perfect and facilitate the operation of washing, the articles to be washed being passed through the machine with an intermittent movement and out between wringing rolls, suitable means being provided within the machine for working out the dirt.

A further object is to provide certain other new and useful features in the construction and arrangement of parts all as hereinafter more fully described reference being had to the accompanying drawings in which,

Figure 1 is a side elevation of a device embodying the invention; Fig. 2 is a longitudinal .vertical section through the same; Fig. 3 is a transverse section substantially on the line ac-m of Fig. 1; Fig. 4 is a similar section substantially on the line yy of Fig. 1; and Fig. 5 is a plan view of the machine.

As shown in the drawings 1 represents a suitable tank or receptacle adapted to contain water supported upon suitable legs 2. Secured to each end of the tank 1 are brackets 3 forming bearings for small rollers 4 and 5 and mounted within the tank adjacent to each end thereof are two pairs of rollers,- a pair of feed rollers 6 at the forward end of the tank and a pair of wringing rollers 7 at the rear of the tank, the lower roll 8 of each pair being mounted in bearings upon the inner sides of the walls of the tank and the upper roll 9 of each pair being mounted upon a shaft 10 which is extended through vertical slots in the side walls of the tank to move freely therein. A. collar 11 is provided on the shaft 10 of each roll adjacent to the outer side of the walls of the tank and to these collars are attached coiled springs 12 at one end, the opposite ends of said springs being secured to pins projecting from the supporting frame of the tank. These springs thus exert a force to hold the

rolls

8 and 9 in yielding contact with each other and the pair of rolls 7 at the rear end of the machine is preferably provided with a covering 13 of rubber or other suitable yielding material so that these rolls will serve as wringing rolls when the clothes pass between them and out of the rear end of the machine.

To feed the garments to be washed through the machine, two endless belt carriers are provided, the lower belt 14 passing over the roll 4 on the bracket 3 at the for ward end of the machine and upward at an inclination through the end wall of the tank and between the feed rolls 6, thence along the bottom of the tank beneath an idler 15 adjacent to the pair of rolls 7, then outward between said pair of rolls through the rear end of the tank and downward over the roll 4. The lower run of the carrier passes over

idlers

16 and 17 mounted in bearings on the legs 2 some distance below the bottom of the tank and the portion of the carrier between the pairs of rolls within the tank is preferably left slack so that it will lie upon the bottom of the tank. An upper endless carrier belt 18 passes over the roll 5 on the bracket 3 at the forward end of the machine and between the pair of rolls 6, thence through the machine beneath the idler 15 and out at the rear end of the machine between the pair of rolls 7 and upward over the roll 5. The run between the roll 5 at the rear end of the machine and the similar roll at the forward end of the machine passes over and is supported by idlers 19 and 20 mounted in open bearings in bracket arms 21 extending upward from the side walls of the tank. The portion of the carrier between the feed rolls 6 and the wringing rolls 7 within the tank is left slack the same as the similar portion of the carrier 14 so that the articles to bewashed which are fed in between the feed rolls 6 upon the inclined portion 22 of the belt 14 will lie between the two slack portions of the two belts within the tank, free to change their position and spread out so that they will be subjected to the action of the water 7 and a series of heaters 23 in the tank.

T0 beat or pound the clothes as they are fed through the tank upon its bottom by the carrier belts, a series of transverse strips 23 are provided, these strips being set on edge in parallelism and guided in their vertical movement by suitable guides 24 on the inner face of the side walls of the tank. T0

raise and lower these beaters so that they will beat or pound the articles to be washed, a carrier is provided consisting of a longitudinally extending bar 25 supported within the tank near the top thereof by

transverse bars

26 and 27 to which the longitudinal bar is firmly secured at its upper edge. Each beater 23 is attached to the bar 25 by a rod 28 having a hooked lower end engaging a bearing loop secured to the upper edge of the beater at its center. The rod passes upward through suitable bearing clips secured to the side of the bar 25 and through bearings in a bracket 29 on the upper edge of said bar, free to slide in said bearings; Sleeved upon the rod between the upper end of the bracket 29 and a collar 30 secured to the rod is a coiled spring 31, and thus when the bar 25 is lowered to lower the beaters and said beaters come in contact with material in the tank, said beaters may rise a short distance against the action of the springs 31 and by pivotally attaching the beaters to the bar 25 by means of the rods 28, said beaters are free to move upward at either end or tilt, but are guided at all times in their vertical movement by the guides 24 on the side walls of the tank.

T0 actuate the beaters by raising and lowering the bar 25, two

parallel shafts

32 and 33 are mounted in bearings upon the bottom of the tank and extend transversely thereof, said shafts being provided at each end with a crank arm 34 or other member serving the purpose of a crank and motion is transmitted from the crank arms to the

bars

26 and 27 by means of connecting rods 35 attached at their upper ends to the ends of the bars and at their lower ends to the crank arms or their equivalents. Power is applied to turn one of the shafts by means of a belt 36 or power may be applied thereto in any other convenient manner, and motion is transmitted from said shaft to the shaft 33 by means of a belt 37 running over pulleys upon said shafts and these pulleys 38 may serve as crank arms for attaching the connecting rods 35 to the shafts by attaching the lower end of said rods to the pulleys.

The upper roll 9 of the pair of feed rolls 6 and the similar roll of the wringing rolls 7, are positively turned to feed the carriers 14 and 18, by swinging arms 39 pivotally mounted intermediate their ends upon the shafts 10 of said rolls and pivotally attached to the upper ends of said arms 39 are dogs 40 to engage ratchet wheels 41 secured upon the shaft 10 adjacent to the collars 11. Secured upon the shaft 33 adjacent to each side of the tank is an eccentric 42 engaged by an eccentric strap 43 carried by an arm 44 pivotally attached at its upper end to the side of the tank. Connecting rods 45 con nect the lower ends of the arms 39 with the lower ends of the straps 43 and thus when the shaft 33 is turned the eccentrics 42 will swing the arms 44 and the arms 39 will be turned by the connecting rods 45, and actuate the shafts 10 with a step by step movement through the medium of the ratchet wheels 41 engaged by the dogs 40 carried by the said arms. The carrier belts are thus fed through the tank with a slow step by step movement carrying the clothes beneath the beaters within the tank which beaters are given a comparatively rapid actuation by the cranks on the

shafts

32 and 33. By positively driving the pair of rolls 6 and also the pair of rolls 7 the slack in the two carriers within the tankis maintained and the outer runs of said carriers are drawn tight so that the inclined portion 22 of the carrier 14 forms a moving table upon which the articles to be washed are placed and spread out so that they will be carried through by the carriers and properly subjected to the action of the water and the beaters. The extended inclined portion of the carrier 14 at the rear end of the machine corresponding to the portion 22, also forms a moving table upon which the clothes pass out from between the wringing rolls 7.

Having thus fully described my invention what I claim is 1. A washing machine comprising a tank, a series of vertically movable transverse beaters within the tank near the bottom thereof, a longitudinal bar to which the heaters are yieldingly attached, a transverse shaft beneath the tank, eccentrics on said shaft, means for imparting a vertical motion to the longitudinal bar from said eccentrics, two endless carrier belts having mating slack portions within the tank upon the bottom thereof beneath said beaters, one of said belts extending beneath the tank and the other above the tank, a pair of mating rolls at each end of the tank between which the belts extend for positively driving the same, a ratchet wheel to drive one roll of each pair, levers, pawls on said levers engaging the ratchets, and means connecting said levers to actuate the same simultaneously.

2. A washing machine comprising a tank, a series of parallel transverse bars in the tank forming beaters, guides on the sides of the tank for said bars a bar extending longitudinally of the tank and transversely of the beaters, spring supported rods carried by said bar and pivotally attached to said beaters intermediate the ends thereof, and means for raising and lowering said bar to actuate the beaters.

3. A washing machine comprising a tank, a series of bars within the tank extending transversely thereof and forming beaters, a series of vertical guides on the tank for the beaters, a bar extending longitudinally of the tank across the beaters, a series of rods mounted in bearings on said bar and pivoth ally attached at their lower ends to the upper edges of the heaters, springs on the rods to yieldingly hold the heaters against vertical movement relative to the said bar, and means for raising and lowering the bar to actuate the heaters.

4:. A washing machine comprising a tank, a series of vertically movable heaters within the tank, transverse shafts mounted in bearings beneath the tank, cranks on the shafts, connecting rods attached at one end to the cranks, means within the tank for simul taneously lifting the heaters to which means the upper ends of the connecting rods are pivotally attached, a pair of rolls within the tank at each end thereof, endless carrier belts extending between the rolls of each pair with a slack portion within the tank beneath the heaters and the outer portion of one belt extending beneath the tank and the outer portion of the other belt extending above the tank, springs for holding the rolls of each pair in yielding contact, a ratchet connected to the ends of one of the rolls of each pair, pivoted levers, pawls carried by said levers engaging the ratchets, and means for actuating the levers simultaneously to turn the rolls.

In testimony whereof I aflix my signature in presence of two witnesses.
