WASHING MAcnINE.

Application led January 17, 1923. Serial No. 613,195.

To all whom z't may concer/n.'

Be it known that I, HERMA-N I. LIPPARD,

' a citizen of the United States, residing at to be cleansed are actuated by utilizing the motive power furnished by steam generated in the` machine itself. In such machines,

' however, the steam soused is generated in a special chamber or receptacle provided for this purpose and independently of the steam generated in the boiler within which are the articles to be cleansed. Hence, the motive power of the steam generated in the clothes boiler is wasted except for the effect it has in assisting in cleansing the articles located Within the clothes boiler.

The particular object of the present invention is to provide a washing machine in which the motive power f-urnished by steam generated in the clothes boiler is utilized to actuate the agitating means for the clothes. Thus it is possible to materially reduce the size of the washing machine by the elimina" tion of the additional receptacle and its connections neccessary in former machines forI `furnishing steam for this purpose. This is particularly advantageous where the machine is intended for domestic use, in which case the size of the device is a matter of prime consideration. Likewise, the elimi` nation of these extra parts lessens the likelihood of leaks and other disorders occurring in the machine, the repair of which might prove quite diiicult for the operator.

A further object of the invention is the provision of an improved form of automatic valve-actuating mechanism forl controlling the admission and exhaust of steam to and from the engine which is provided for driv-` ing the moving parts of the machine. Another feature is the provision of Va separate receptacle for the cleansing of colored or other articles that cannot be boiled, this re-I -ceptacle forming an intregal part of the machine and being adapted to be oscillated by the same means as act-nate the agitating means within` the clothes boiler.

Other features and advantages'of the improved machine will appear clearly from the detailed description given hereinafter and the accompanying drawings in which the same reference numerals indicate like parts throughoutv the several views, vand wherein,

Figure 1 represents a front elevation of the improved washing machine, certain parts thereof being broken away or shown in section in order to disclose more clearly the interior construction and arrangement of parts;

shifted to again admit steam to the outer end of the cylinder; and f' Fig. 9, an enlarged perspective of certain parts of the automatic valve-actuating. mechanism, the parts being shown removed from the drive-shaft and separated for sake In the drawings, 1 represents a metal `casing 'which is mounted on legs 2 and forms interiorly a combustion chamber 3 and an ash pit 4 separated by a grate 5. A. flue 6` leads-from the rear of chamber 3, Fig. 2, to carry olf the products of combustion. Casing 1 is provided at its front with' a lire door 7 and an ash pit door 8 whereby access may be had readily' to either of these compartments. Mounted securely in the upper end of casing 1 1s the verticall -disposed, cylindrical, steam pressure boi er 9, the latter being provided with a concave bottom 10, which projects well down into the combustion chamber 3 of the furnace or heater. A horizontal drain pipe 11 eX- tends across combustion chamber 3 and at its outer end projects through the side of casing 1 where it is provided with adrain cock 12. The inner end of pipe 11 is suitably connected at 13 to an opening in the bottom 10 of the boiler 9 s o that water may be drained out of the boiler when desired.

The boiler 9 is provided, as shown in Fig. vl, with a dome-shaped removable cover 14. Cover 14 is provided at intervals about its outer periphery with slotted lug's 15 with -which are adapted to engage corresponding swinging fasteners 16, pivotall secured to the boiler at their lower and aving wlng nuts 17 at their upper ends, to clamp, the cover down securely on the boiler so as to prevent any escape of steam. JA steam gage v13 and a pop valve 19 are provided' on top of cover 14 to respectively indicate when the desired steam pressure-has been obtained and to relieve the boiler of excess steam when the pressure is too great. L y

0n the left side of boiler 9 above drainy cock 12, there are secured, one above the other,two vertically perforated lugs 20, 21. These lugs receive a vertical post 22 which passes downwardly through the perforations in the lugs and is held in place by means of a removable collar 23 secured to post 22 by a pin-24 passing through suitable registering openings 1n these parts.\ Thus post 22 is free to revolve in lugs 21 and 22. At the upper endof post 22 there is rigidly secured at its inner end an armf 25 having a perforation 26 in its outer end. A threaded post 27 extends through the opening 26 in -arm 25 and at its upper end above'arm 25 is provided with a large wing nut 28. The lower end' of p ost 27' is secured in any suitable manner to the center of the cover'. 14 of" the boiler, This may be accomplished readily as shown 'by providing cover 14 centrally thereof with an annular, upstanding flange 29 within which the lower end of post 27 projects and 'is securedby a set screw 30,V thereby rigidly connecting the arm and cover together. The purpose vof this arrangement, as will be seen, is to provide means for readily raising cover 14 from the boiler 9 and swinging the cover to one side. The rais- 1ng of the cover 14 from the boiler 9 is accomplished by merely rotating wing nut a spherical or globular clothes receptacle or agitator 31. Receptacle 31 is formed of light sheet Amet-al and is provided at its top with a hinged door 32 (Fig. 1) of the same material and having a handle 33 so that the door may be opened when access to the interior of the receptacle 31 is desired. Suitable means (not shown) are also provided to secure door 32 when it is closed. The sheet metal of which receptacle or agitator 31 and door 32 1s made is provided, preferably all over, with smallr perforations 34 lso as to permit the free passage therethrough of the water in boiler 9 either'when receptacle 31 is at rest or duringits oscillatory motion when the machine isin operation. Interiorly agitator receptacle 31 is provided with a series of diagonally arranged vanes 35 which are designed to assist in agitating the clothes in agitator 31 when the latter is oscillated Agitat-'or receptacle 31 is mounted for oscillation in boiler 9 by securing thereto exteriorlyV and centrally of its left.side a short, cylindrical stub-shaft 36 which supports the left side of the receptacle in a bearing block 37 attached interlorly to the left side of boiler 9, as shown in Figs. 1 and 2. Bearing block 37 receives stub-shaft 36 in a vertical slot 38 therein closed at its lower end and open at its upper end so that the stub-shaft may be removed from box provided at this point serves to prevent the escape of steam from boiler 9 about drive-shaft 39. Interiorly thereof and in line with drive shaft 39 agitator-receptacle 31 is provided with a. centrally-perforated, annular, clamping member 41y and on its exterior at the same point with a U-shaped member 42. Members 41 and 42 are securely connected to agitator 31 by means of bolts 43 passing through suitable registering openings provided in the several members. The vertical slot 44 in U-shaped member 42 is bordered by a projecting flange 45, while slot 44 is made square at its lower, closed end to receive the squared portion 46 on the end of drive-shaft 39, whereby motion may be transmitted to agitator receptacle 31 upon movement of the shaft. A machine screw 47 extends through the central perforation in inner clamping member 41 and a corresponding opening in agitator 31, the outer threaded portion of the screw engaging with a centrally-located, threaded recess in the outer end of squared portion 46 of drive-shaft 39, thereby firmly securing all the parts together;f

It will thus be seen that in the construction described, agitator 31`may be released from its bearings and removed readily from boiler 9 by simply removing machine screw 47, whereupon the right side of receptacle 31 is free to drop away from the squared end of drive shaft 39, there being sufficient clearance between the bottom of receptacle 31 and the concave bottom 10 of boiler 9 to permit this. The left side of receptacle 31 is then raised slightly so as to remove stub-shaft 36 from bearing block 37 when receptacle 31 may be removed from the boiler by simply lifting it vertically.

Extending to the right of casing l and connected securely thereto in any suitable manner is the supporting framework which carries the remaining parts of the machine, such as the steam engine and its allied parts and the colored clothes receptacle. rl`hs framework comprises an upper pair of side,

horizontal members 48, 49 and a lower pair CII of side, horizontal members 50, '51. These two pairs of horizontal members are rigidly connected at their right extremities by upper and lower end, transverse members 52, 53 respectively. An upper,I intermediate, transverse member 54 also connects thev upper pair of horizontal, side "members 48, 49. A pair of end, vertical members 55, 56 and a pair of intermediate, vertical members 57, 58 serve to support the other members of the framework in position.

The right end of drive-shaft 39 is mounted in' a suitable bearing 59 provided on the upper face of frame member 54. Mounted bctween upper lframe members 52 and, 54 is the colored clothes receptacle 60. Receptacle 60 is also formed of light sheet metal and is preferably cylindrical in shape. At its left side and on its horizontal axis at 61 receptacle 60 is securely connected by any suitable means to the right end of driveshaft 39,which latter projects through bearing 59 for this purpose. Diametrically opposite on its right side receptacle 60 is pros vided with a short stub-shaft 62 which is mounted in a bearing 63 attached to the upper face of upper frame member 52. The outer end 64 of stub shaft 62 projecting beyond bearing 63 is squared so that it may receive a crank v(not shown) for manually operating the machine when so desired.

Colored clothes receptacle 60 is provided at its upper portion with the usual hinged door 65 having la handle 66 and suitable fasteners 67, 68. Interiorly of receptacle 60 there is secured a series of spaced, transverse vanes 69 extending across the inner periphery of the receptacle alternately from the sides thereof to assist, when the machine is operated, in the agitation of the articles placed in the receptacle vfor cleansing.

Hence it will be seen that, upon the actuation of drive shaft 39, the agitator or main clothes receptacle 31 in boiler 9 and the colored clothes or auxiliary receptacle 60, by reason of their connections with the ends` of shaft 39, will be rotated in synchronism and 95 .to the same extent as is the drive-shaft.

The engine for propelling drive-shaft 39, together'with its automatic, valve-shifting mechanism will Inow be described. Rigidly mounted in any suitable manner on the upi per face of upper frame member 49, as by means of brackets 70, 71 on either side thereof and securely fastened to the several parts, is a horizontally-disposed, steam cylinder 72 provided at one side with the usual steam 105 chest 73 in which is located the slide valve (not shown) 4for distributing steam altervnately to the opposite ends of the cylinder to reciprocate piston 74 together with its nod 75." A pipe 76 extending from the upper 110 portion of boiler 9 is connected at it-s outer end to steam chest 73 and thus serves to conduct the steam generated in boiler 9 to the steam chest, whence it is fed into cylinder 72 as described. rl`he flow of steam 115 through pipe 76 is controlled by means of a conveniently located valve 77. The rod connected to and through which .the slide valve in steam chest 73 is controlled is shown at 78, the outer end thereof being perforated for a purpose later described. At 79 is the exhaust outlet for steam cylinder 72.

I The lower face of piston rod 75 at its outer portion is in the form of rack 80 having its toothed surface disposed downwardly. Rack 80 extends across drive-shaft 39 and the teeth thereof engage with the teeth of a pinion 81 fixed to drive-shaft 39, thereby providing' for oscillation of the drive-shaft 39 whenever rack 80 is reciprocated. A col- 13a the rig 1an-s2 fixed on drive-shaft 39 to the lea of pinion 81 prevents possible shifting of the` pinion in that direction. Pinion 81 is fixed to drive-shaft 39 by means of an extended key 83 provided on the shaft and a corresponding keyway 84 in the inner `periphery of the lpmion. An annular extension 85 on t side of pinion 81 is provided with a radially-disposed threaded opening in which is located a -set screw 86 which is adapted, when tightened, to engage shaft 39 and thus secure pinion 81 against collar 82. When set screw 86 is loosened pinion 81 may be shifted to the right until disengaged from rack 80 but still in engagement with extended key 83, at which point it may again be secured against movement by means of set screw 86. With rack 80 and pinion 81 out of engagement the machine may be manually operated by means of a crank attached to the squared end 64 of stub shaft 62 to causev oscillation of the washing receptacles vwithout the necessity of also operating piston 74 back and forth in steam cylinder 72.

When steam cylinder 72 is functioning and at which time pinion 81 is in its normal position beneath' rack 80, a roller 87 mounted to revolve on the outer end of an arm 88 rigidly attached at its inner end tothe side of boiler 9 is 'in continuous engagement with the upper or smooth face of rack 80 so as to always maintain proper engagement of these parts.

In the operation of the machine it is not necessary that the washing receptacles 31 .and 60, when oscillated, shall make a com-- plete revolution about their horizontal axes, ut rather it is preferred that they be oscil lated through an arc of about 330". Consequently drive-shaft 39, which directly controls the movements of the washing receptacles, must be oscillated through a corresponding arc, being reversed at the ,end of each osclllation due to the automatic actuation of the mechanism which shifts the slide valve not shown) associated with steam cylinder 2 and 'the consequent movement of piston 74 in the opposite direction. In'this manner ythe washing receptacles 31 and 60 are not allowed to t on a dead center, while the reversal of t eir direction of moves ment at the end of each oscillation is aided by the weight of the clothes within the receptacles.

The automatic mechanism for shifting the slide-valve associated with steam c linder 72 will now be described. On drive s aft 39 to the right of pinion 81 and beyond key 83 end.A Pivotally and adjustably connected at one end to the outer end'of arm 91 of collar 90 is an eccentric rod 94, the opposite end of the `latter having a longitudinally-adjustable pivotal connection 95 withthe outer end ofthe slide-valve rod 78 of the steam cylinder 72. Arm 91 is connected to the end of eccentric rod 94 by means of a'bolt 96 which extends through the slot 92 in arm 91 and an opening in the end of rod 94 and is secured by nut 97. vInterposed between the perforated end of rod 94 and the serrated face of arm- 91 of collar 90 is a washer 98' having on its right face a series of transversegserrations 99 which, when the parts are secured in place, engage with the serrations 93 on the left face of arm 90 to prevent movement of bolt' 96 in slot 92 from the position in which it is desired to maintain it. Thus the presence of the serrations renders it unnecessary to screw the nut on the end of bolt 96 until the parts are tightly clamped together, thereby preventing free pivotal action between eccentric rod 94 and arm 91, but rather a slight looseness isA allowed in order to permit proper functioning of the right of and abutting against collar is a third collar 100 of an external diameter somewhat greater than that of collar 90. Located diametrically opposite each other on the left face ofcollar 100 are fixed pins 101 land 102, the pins being of sufficient length to engage with the front edge 103 and the rear edge 104 of arm 91 of collar 90 when collar 100 is oscillated on shaft 39 as will be later described. Formedv on the outer periphery of collar 100 midway between pinslOl, 102 is an. integral, lug 105 having radiallyextending end faces 106,- 107. The upper perforatedend of a rod 108 is pivotally connected centrally of the left face of lug 105 on collar 100 by means of. a pin 109 suitably Ysecured in the lug.

`and at ,their right extremities to upper transverse frame member 54. Members 110 and 111 are connected intermediate their eX- tremities by two parallel, transverse, frame members 112, 113, which latter are horizontally perforated midway of their lengths.

AI U-shaped yoke 11'4, horizontally perforated at its upper extremities, is pivotally suspended to swing from frame members 112, -113 by means of suitable bolts secured in the perforated extremities of yoke 114 and the corresponding perforations in members 112, 113. Rod 108 extendingdownwardly from collaIl 100 passes through a central perforation 115 in the base of U-shaped yoke 114 and has its outer threadedextremity fitted with a nut 116 and a washer 117. Mounted on the lower portion of rod 108 with its lower end resting on the upper face of the base of yoke 114 is a coil spring 118. Rod 108 -is threaded for some distance above the top of spring 118 in order to receive a nut 119 which engages with a large washer 120, also mounted on rod 108, to provide for adjusting the tension of spring 118. A nut 121 on rod 108 above nut 119 is used to lock the parts in place after the desired adjustment has been secured.

On shaft 39 to the right of and abutting against collar 100 is a fourth collar 122. Collar 122 is secured to shaft 39 by means of a cross pin 123 extending through suitable registering openings in shaft 39 and the collar. An integral radial arm 124 extends from the outer periphery of collar 122 and is of sufficient length so that a removable pin 125 projecting from the outer portion of the left face thereof will, upon oscillation of shaft 39 and with it collar 122, engage with either of end faces 106, 107 of lug 105 on collar 100.

As hereinbefore stated, the clothes receptacles 31 and 60 are intended to be oscillated in an arc of about 330. Consequently drive shaft 39 must be oscillated in a corresponding arc and, since collar 122 carrying arm 124 is fixed to shaft 39, arm 124 will also swing through the same arc during each osm cillation of the washing receptacles to bring about automatic shifting of the slide valve and reverse movement of the parts Referring now to Fig. 5 of the drawings, the several parts of the valve-control mechanism are shown in their relative positions just after rack 80 has reached the end of its movement to the right and the slide valve of the steam cylinder 72 has been shifted in the same direction due to the expansion of spring 118, while clothes receptacles 31 and 60 and operating arm 124 on collar 122 have also reached the end of their oscillation in one direction, i e., clockwise, and -are about to oscillate inthe opposite direction, i. e., counter-clockwise. At the beginning of this reverse movement (Fig. 5), it is to be noted that operating Aarm 124 is disposed at an angle of approximately 15 to the right of a vertical line passing through the center of shaft 39, while at the end of this oscillation (Fig 6) it is disposed at an angle of approximaely 15O to the left of the same vertical line; in other words, operating arm 124 during each oscillation passes through an arc of approximately 330o In operation, assuming the parts to be in position as shown in Fig. 5, the automatic shifting mechanism for the slide-valve of steam cylinder 72 functions as follows:

Drive shaft 39 rotates counterclockwise, as rack 80 moves to the left, thereby causing operating arm 124 on collar 122 to Swingin the same direction until pin 125 on the latter engages with end face 106 of lug 105 on collar 100. Continued movement of arm 124 causes the rotation therewith of collar 100, which as stated is freely mounted on shaft 39 which results in a downward ymovement of rod 108 to compress spring 118 against the lower portion of yoke 114, the latter then swinging to the left (F ig.'6) as will be readily understood. Due to the distance between pin 125 and pin 109 connecting the upper end of rod 108 with lug 105 of collar 100 when operating arm 124 reaches its extreme left position (Fig. 6), the pivotal connection of the upper end of rod 108 with lug 105 of collar 100 will have passed beyond its lowermost position, or the dead center, and spring 118 will be free to expand. Upon expainsion of spring 118 (Fig. 7), the rotation of collar 100 in the same direction will be accelerated, thereby bringing pin 102 on the left face of collar 100 into engagement with edge 104 of arm 91 of collar 90. Upon continued movement of collar 100, due to further expansion of' spring 118, arm 91 will be swung to the left, resulting in movement of eccentric rod 94 in the same direction (Fig. 7) to shift the slide valve of steam cylinder 72 and cause the desired reverse movement of the parts of the machine. In 'the reverse movement, the functioning of the parts is the same as in the operation just described, except that the parts move in the opposite direction. This may be seen in Fig. 8, wherein operating arm. 124 is shown after it has been oscillated clockwise 330o about shaft 39, to its original position of Fig. 5, due to the reciprocation of rack 80 to the right, and thus carried lug 105 of collar 100 together with the pivotal connection of the upper end of rod 108 therewith beyond its lowermost position, the dead center, thereby compressing spring 118 and'swinging yoke 114 to the right. Spring 118 then `expands to accelerate the rotation of collar 100, while 105 on the latter engages with edge 103 of arm 91 of collar 90 to swing arm 91 to the right thereby again shifting the slide valve through eccentric rod 94 and permitting steam to enter the opposite (outer) end of steam cylinder 72 to again cause reversal of movement of the partsfof the machine in the manner described.

The same general operation of the machine is as follows Steam valve 77, which controls the starting and stopping of the washing machine, is first closed, whereupon cover 14 of boile'r 9 is swung to one side and the necessary quantity of water poured into boiler 9 and agitator 31. All clothes or other articles that can be boiled are placed in agitator `31. A fire is then started in the grate 5 in combustion chamber 3. After the soap or other `desired washing compound has been put i'n boiling point the desired amount of water is drawn olf from drain cock 12 and poured into receptacleI 60. Door 65 of receptacle 60 is then closed and secured by means of fasteners 67, 68.

When the steam gage 18 indicates sufficient pressure in boiler 9, say 15 or 2O pounds, lthe engine is started by opening lvalve 77 to admit the steam from boiler 9 to cylinder 72. As piston 74 is reciprocated baclr and forth an oscillatpry motion will be imparted to the washing receptacles 31 and 60, as hereinbefore described kin detail.

This motion will gradually increase in rapidity as the machine gets under way until, when in full operation, the clothes or other articles and the Water in washing receptacles 3l and 60 will be in a violent state of agitation, which when sufficiently prolonged Will bring about a thorough cleansing of the articles therein. This agitation` is aided considerably in the case ofthe boiler 9 by the presence of thevanes 35 inside of agitator 31 and in receptacle 60 by vanes 69.

Should it become necessary to change the relative position of the slide-valve within steam-chest 73' this 'may be accomplished readily by meansof the longitudinally ad; justable connections 95 between valve rod 78 and the outer end of eccentric-rod 94. If the length ofv the reciprocatory or shifting movements of the slide-valve requires changing, this may be done by merely loosening the nut onthe right end of bolt 96 and securing the end of eccentricfrod 94 in a different position in theslot 92 in the end` of arm 91 of collar 90. The nearer the outer end of the slot 92 eccentric-rod 94 is connectedy to arm 91, ythe greater will be the shifting movement of the slidefvalve, While this movement may be decreased by connecting eccentric-rod 94 nearer to 'the inner end of slot 92, as may be readily understood.

Should it be desired to operate the. washing machine manually without actuating unnecessary parts thereof, set screw 86 is firstloosened to permit the movement of pinion 85 to the righton drive-shaft 39 out of mesh with rack 81 thusdisconnecting steam cyli inder 72 yand its parts. Pin 125 in the end of arm 124 of collar 122 on shaft 3 9 is then removed to prevent operationof the shifting mechanism for the slide-valve. when drive-- shaft 39 revolves. suitable crank may then be attached to the squared end 64 of stubshaft 62 and the Washing receptacles 31 and 60 operated.

Any kind of combustible fuel may be used in chamber 3 of the furnace. In fact, it is not intended to restrict the invention to a Washing machine having a furnace or heater construction such as is shown and described, but any suitable heating means, may Well be used to heat the water.

Although the machine is primarily intended for Washing purposes, it is suscep-I i tible of other uses. In fact, the machine is readily adapted for use as a steam pressure apparatus for canning purposes, this being accomplished by merely removing the agitator 31 from boiler 9, whereupon the receptacles cntaiing the `foodstuffs to be^ canned are placed in the boiler, the cover thereof replaced, and the receptacles and foodstuffs therein then subjected to the action of the steam generated in the boiler. The adaptablih'ty of the machine for steam pressure canning is rat-her important since it will mean quite a saving tothe purchaser.

The purchase of a steam pressure canner of` the capacity of the boiler of the present machine would be quite expensive for an apparatus to be used only during the usual short canning period each year, lwhereas the ,present machine, While being used ordinarily throughout the year for Washing purposes, may at any time 'be used as a pres'` sure canner.

It 'is contemplated -that numerous structural changes may be made in the machine without departing from the scope of the invention, except as the same may be limited by the appended claims.
