WASHING-MACHINE.

Specification of Letters Patent.

Patented Mar. 18, 1913.

Application filed June 13, 1911. Serial No. 632,845.

To all whom it may concern:

Be it known that I, JoNAH DAvins, a citizen of the United States, residing at Hazleton, in the county of Luzerne and, State of Pennsylvania, have invented new and useful Improvements in Washing-Machines, of which the following is a speci-, fication.

This invention relates to washing machines of' that class in which the cleansing of garments is effected by the action of water or suds forced therethrough by means of pumps, the water being discharged upon the surface of the clothes and forced through the same by the action of pumps, as stated.

The present invention has for its principal object to produce a simple and eflicient machine of the class described equipped with two umps operating alternately so that one of said pumps shall always be ac.- tive when the machine is in operation to discharge water upon the cothes, while the other pump is active to force the -watr throu h the clothes.

A. urther object of the invention is to construct a simple and eflicient machine of the class described including a framework that supports the. ways or guides for the cross heads connected with the piston rods of the pumps which extend in opposite directions from a casing or receptacle, said framework being also made use of to support tables at opposite sides of the casing of the machine, one of said tables being adapted to support the soiled clothes, while the other table supports the clothes after they have been cleansed and passed through the wringer. I

Still further objects of the invention are to simplify and im rove the general con-f struction and operation of a machine of the character described.

With these and other ends in view which will readily appear as the nature of the in-, vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts. which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings-, Figure 1 is a side e1evation of a washing machine constructed in accordance with the invention. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a top plan view with parts broken away. Fig. 4 is a bottom plan view. Fig. 5 is a horizontal sectional view enlarged taken on the line 5-5 in Fig. 2. Fig. 6 is a vertical sectional detail view taken on the line 6+6 in Fig. 3. Fig. 7 is a detail view in elevation showing the foot lever 31, the retracting spring 32 and related parts.

Corresponding parts in the several figures are denoted by like characters of reference.

The body or casing of the improved Washing machine has been illustrated as consisting of a rectangular box 1 which may be of any desired dimensions, said box being supported upon legs or uprights 2, 2 which are braced in any convenient manner to insure strength and rigidity. Adjacent to diagonally opposite corners of" the box 1 and exteriorly of the latter ,are formed vertical casings 3', 3 which are closed at their upper and lower ends but which communicate adjacent to their upper ends with the interior of the box 1 through slots or apertures 4 in the ends of said box.

Arranged within the box 1 and supported upon the bottom of the latter are pump barrels 5 which communicate through openings 6 in the ends of the box with the lower ends of the casings 3, saidcasings constituting ducts for the passage of water, as will be presently more fully described. The pump barrels 5 which have been shown as being substantially square in cross section are dis posed adjacent to the side walls of the box or casing 1 which have been shown as also constituting side walls of the pump barrels, in order to promote simplicity of construction. It is to be understood, however, that the pump barrels may be manufactured 1ndependently of the box or casing 1' and may be mounted and secured in said casing in any desired manner.

It will be seen that the pump barrels 5' extend from the casings or ducts 3 inwardly within the casing, and said pump barrels are provided adjacent to their inner ends with inwardly opening valves 7. Operating in each pump barrel is a piston 8 having a Valve or valves 9 opening outwardly, d

each of said pistons has a rod extending through a packing box 11 in the outer wall of one of the casings 3, each of said piston rods being connected with a cross head 12 slidably supported upon ways or guides 13, said Ways or guides being firmly supported by means of frames 14 having legs 15. The

frames 14, which are intimately associated with the structure of the box or casing 1, extend from the opposite ends of said box or casing, and saidframes serve to support tables 16 of galvanized iron or other suitable non-corrodible material. In the construction of this machine it is evident that the piston rods to make the pumps effective must be guided for a stroke of the requisite length away from the ends of the box or casing 1 by providing the frames 14 and the tables 16, the cross heads associated with the piston rods are covered and protected, and the space necessary for the operation of the pisto-n rods is not merely closed in, but it is rendered available to provide the tables one ofwhich is intended and adapted to support the soiled clothes that are to be washed, while the other table is adapted to receive the clothes as they come from the machine,

- 'as will be presently set forth.

Supported for rotation in bearings beneath the bottom of the box or casing 1 is a shaft 17 carrying at.the ends thereof band wheels 18 and 19, said band wheels being each equipped with a wrist pin 20 connected by a pitman' 21 with one of the cross heads 12, thereby causing said cross heads to be driven by the rotation of the shaft. By properly connecting the pitmen with the wheels 18, 19, the pistons in the two pump barrels will be alternately operated so that one will make a suction stroke, while the other ,makes ,its discharge stroke. One of the band wheels, 18, is adapted to receive motion by means of a bolt or band from a upon one of the roller carrying shafts 28 of a wringer 29 of suitable construction which is supported upon one end of the box 1 directly above the receiving table 16 at one end of the machine. A suitable clutch of well known conventional construction may be included in the means for transmitting motion to the wringer, and said clutch may be actuated; by means of a treadle or foot lever 31,

which is normallv held in an elevated position by means of a spring 32, it being understood that by depressing the treadle against the tension of the spring the clutch will be actuated to cause motion to be transmitted to the Wringer. By enabling this mechanism to be controlledby foot pressure, the hands of the operator will be left free to handle the clothes to supply the same to the rollers of the wringer, and to guide the same, as required. 1

Supported within the box or casing 1 partly upon the pump barrels 5 and partly upon cleats or flanges 32 is a screen 83 composed of wire netting secured upon a suitable frame 3-1. This screen is intended and adapted to support the clothes that are to be operated upon and which may be introduced into the box orcasing through a lid 35 hingedly associated with the top 36 of the casing 1. Said top may be firmly secured in position by means of cross strips 37 that are bolted in place, it being unnecessary to detach the saidtop 36, except perhaps for occasional repairs. An aperture 38 obstructed by a plug 39 may be provided for the purpose of enabling soiled water or suds to be drawn from the machine. Thesides of the box or casing support guards 40 that serve to inclose and cover the various band wheels and other moving parts to prevent the clothes of the operator, standing alongside the machine from becoming entangled with such moving parts when the machine is in operation.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. The clothes that are to be washed are introduced through the opening obstructed by the lid 35 and placed upon the screen 33 where they may be evenly distributed. Water and soap are now placed in the machine, after which power is applied to rotate the shaft 17,

thereby actuating the pumps whereby the water will be suckedor drawn through the clothes, the-Wateror suds being carried upward through the ducts formed by the casings 3 and discharged through the apertures 4 into the upper part of the casing ontop of the clothes. Vhile one pump operates to draw the. water through the clothes, Water will be discharged upon the clothes from the other pump, and the pumps being disposed at opposite sides of the casing, the distribution of water over the surface of the clothes will be sufficiently equal for all practical purposes. By the continued passage of the water or suds through the clothes, the latter will soon be sufficiently cleansed, and they may then be passed through the wringer to the receiving table or platform.

The improved washin be seen, is very simple 1n its construction, and the principle involved in the operation machine, as will thereof has been found in actual practice to be thoroughly eflicient for the purpose of quickly and thoroughly washing light, as well as heavy, garment-s without injurious rubbing or attrition. 1

Having thus described the invention, what is claimed as new, is

1. In a washing machine of the character described, a casing, pump barrels within the casing adjacent to opposite sides of the latter, a clothes supporting screen resting upon and extending over the space between the pump barrels, ducts leading from the outer ends of the pump barrels to the upper end of the box or casing, pistons and valves operating in the pump barrels, and means for actuating the pistons, v

2. In a washing machine of the character described, a casing, pump barrels within said ducts being constructed exteriorly of the casing and including walls having packi g boxes, rods connected with the pistons and extending through the packing boxes,

suitably guided cross headsconnected with the piston rods, and means for actuating the cross heads to operate the pumps. In testimony whereof I aflix my signature inpresence of two witnesses.
