WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 627,968, dated July 4, 189g.

Applicationled January 30, 1899. Serial No. 703,807. (No model.)

To all whom it. may con/cern:

Beit known that I, PARIS T. BENBow, a citizen of the United States, residing at the vented acertain newand usefullmprovement in Washers, of which the following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a top plan view of my improved washing-machine. Fig. 2 is aside elevational view, part of the near wall being removed to show the interior. Fig. 3 is a cross-sectional View showing the lid thrown back in end elcvation. Fig. 4E is an enlarged elevational view of the upper end of the staff which carries the agitators. Fig. 5 is an enlarged detail side elevational view of the mechanical movement for converting the rotatory movement into a reciprocatory movement. Fig. 6 is a longitudinal sectional view through the same, and Fig. 7 is a, cross-sectional view through the same.

This invention relates to a new and useful improvement in washing-machines, the object being to constructa machine of the character described with two receptacles, enabling the operator to wash clothes in the first and second suds at the same time,suitablemech anism being provided that the agitators in each receptacle can be operated from the same source of power, or they may be disconnected and the power directed solely to one set of agitators in one receptacle. By arranging the two receptacles in a single box the clothes may be wrung out of the first sudsbox directly into the second suds-box, which' saves eXtra handling and allows the garments to become cooled while waiting for the balance of the Wash to be put through the first suds. A false bottom is also provided in each receptacle, which bottoms are preferably made of hard wood and so constructed that the dirt from the clothes being washed settles underneath and is not ground into the wash, thus producing'good results and admitting of a much longer use of the suds.

With this object in view the invention consists in the novel construction, arrangement, and combination of the several parts, all as 1 will hereinafter be described, and afterward pointed out in theclaims.

In the drawings, A indicates a box-like casing as an entirety, which is providedl with a central partition, dividing the same into two compartments B and C, the former being designed for washing the clothes through what is known as the first suds and the latter for washing the clothes through the second suds. The floors of these compartments are preferably corrugated, while the side Walls are providedwith corrugated strips, cornerblocks abeing introduced to till out the cor` ners and also afford additional rubbing-surface. Near each end of these receptacles and in the lower portion thereof are arranged cross rungs c, preferably of wood,l under which are introduced the ends d of a frame D, which framehas mounted in it suitable rungs or wooden bars d/,constituting the false bottom. Frame-railsD are divided obliquely at about their middles, as shown more clearly in Fig. 2, and these two sections of the frame are hinged together, so that it may be inserted in and removed from the compartment, and in inserting or removing the ends d into or from their designed position under the rods or rungs csaid frame-rails are broken or, rather, bent upwardly, as shown by dotted lines in Fig. 2.

d indicates suitable concavities yformed on the upper face of the frame D and near the outer ends thereof, said concavities being designed for cooperation with the rungs c, and by which construction, after the ends of said frame D are placed thereunder, longitudinal movement of said frame is prevented. By curvingthe ends of the frame D, as is clearly illustrated in Fig. 2, said frame will, when properly inserted and pressed down, adjust itself to its locked position under saidrungs c, as is obvious. Suitable openings vare arranged in the receptacles, near the bottoms thereof, for drawing off the water, as is well understood. Y

In ordinary washing the false bottom is used; but where a great number of articles are introduced into the machine this false bottom-.may be removed to give more space, when the corrugated bottom will act as a rubbingsurface.

E indicates a cover on whose under side is too arranged a cleat e, through which cleat passes a rod f, mounted'in the end walls and the central partition of the box, so that said cover can be thrown back, as shown in Fig. 3, for the introduction and removal of the clothes to and from the receptacles. A suitable supporting-'cleat a is arranged inside the box A forsupporting this cover in its closed position.

Mounted on cover E, preferably by being bolted thereto, is a casting G, whose ends are provided with suitable bearings for powershaft H, on the outer end of which shaft is a hand-wheel I, provided with a handle t' for rotating said shaft, or, if desired, a belt may be placed around said wheel where this kind of power is accessible. The inner end of shaft H carries a pinion K, which mesh es with an endless rack formed on a suitable casting- L. Casting L, as shown more clearly in Figs. 5 and 6, is so constructed that the teeth formed thereon make a continuons or endless rack with two straight sides, the ends thereof being connected, as shown. The rear side of this casting is bridged by connecting-pieces Z, from which connecting-pieces extend a rider guide-plate M, which cooperates with a stud or pin N, axially in line with shaft H and pro' jecting rearwardly from the rear face of pinion K. The casting G on its rearA end is formed with an overhanging projection g, which acts as a guide for casting L, holding the same in proper relation to pinion K.

Extending forwardly from casting Lis a rack-bar O, which meshes with a pinion P, mounted in a suitable framing or casting Q. (Shown more clearly in Fig. Pinion P is preferably provided with hubs on each side engaging the casting above and below the same, whereby said pinion is held in position against vertical movement, the casting being provided with suitable bearings, so that the pinioncannothavelateralmovement. Pinion P is also formed with a non-circular (square) opening, through which passes a squared shank R of the staff, carrying the spider-frame R on its lower end, in which spider-frame are mounted pins lr, being what are known as the agitators A suitable Cotter-pin o" is arranged through the upper end of this squared shank, while above said squared portion the shank is preferably circular in crosssection, its upper extremity passing through a guide-bearing in casting or framing Q. A spring S surrounds this circular portion for the purpose ofholding the agitatorsin apower position, but which spring in the event that said agitators meet an obstruction tending to force them upwardly will yield To permit such upward movement, thus rendering the parts not liable to breakage in operation.

T indicates a rackbai' engaging with the opposite side of pinion P, said rack-bar extending longitudinally the machine and engaging a pinion P', mounted in a casting Q', for rotating a staff R", the parts of this second mechanism being substantially the same as that heretofore described. This second mechanism, however, is designed to rotate the agitator in the receptacle C, while the mechanism iirst described is designed to rotate the agitator in receptacle B. In order to disengage the rack T from the pinion P when it is desired that the clothes' in the first receptacle only shall be washed, I elevatelsaid rack, as shown by dotted lines in Fig. 4, and by the use of a hook q on casting Q engaging an eye t of the rack-bar T said rack-bar is held out of engagement with pinion P. When it is desired to have both sets of agitators in operation, it is obvious that rack-bar T is unhooked and engages with the pinion P. The teeth of both of the racks O and T are preferably thicker in their middle portion when viewed from the direction as seen in Fig. 5 for the purpose of permitting said rack-bars to rock slightly when in mesh with their respective pinions, as said rack-bars do not at all times occupy a parallel relation with the face of said pinions, as will be clearly 11nderstood.

The operation of the mechanism above described may be briefiy stated as follows: Shaft His designed to be rotated continuously in one direction to impart a reciprocatory movement to the rack O,A which in turn rotates pinion P in opposite directions and os-A cillates the staff mounted in said pinion, it being understood that the, hand-wheel I, mounted on said shaft H, can be rotated in either direction, the ultimate result being the same. When the pinion P is in mesh also, its operation is substantially the same as that of the pinion P. Continuous rotation in one direction being imparted to shaft H will cause the gear K to mesh with the teeth of casting L, the stud or pin N, engaging the rider-bar M, holding said parts into mesh. Pinion K will force casting L in one direction or the other, depending upon the rotation of pinion K, until the end of the casting is reached, when the pinion will climb up or down the circular arrangement of teeth on the casting, and the rider-bar M terminating there and being in proper relation to the pin Nwill hold the pin in engagement with said teeth until the stud or pin N gets above or below the rider-bar, when pinion K will immediately cause the casting L to move in the opposite direction until the other end thereof is reached, when practically the same cycle of movements is gone through. Casting L is practically a oating rack-bar that is, pinion K is iixed with relation to said casting-and by the' construction of casting Q, in which the rack-bar O is guided, said casting practically acts as a pivot-point for said rack-bar, holding the same constantly in engagement with pinion P, permitting the rear end of said rack-bar, or that end on which casting L is arranged, to move up and down and likewise forward and backward.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my machine can be IOO IIO

made and substituted for those herein shown and described Without in the least departing from thenatu re and principle of my invention.
