To all whom it may concern.-

Be it known that we, CHARLES C. BURTON and DANA H. BENJAMIN, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Washing-Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to the letters of reference marked thereo11,which formpart of this specification.

Our invention relates to an improved wash-' ing-machine; and it consists in the mechanism, construction, and combination hereinaf- "ter pointed out, described, and claimed.

This viewis taken substantially on a vertical longitudinal section of the left-hand end of the machine, and is a part of the left-hand end of Fig. 6, with the bearing, -&c., omitted to avoid complication and better show certain features. Fig. 20 is an end elevation of the head of the cylinder, a portion of the frame, two Valves, and a movable circle, and is taken from the lefthand end of the machine, as shown at Figs. 6 and 10. Fig. 21 is a view of the edge of the movable circle, showing a circular cam-shaped projection thereon.

Like figures of reference refer to like parts in the several figures of the drawings.

Our machine consists, essentially, of two A- shaped end frames I, Figs. 1 and 4, which are bound and tied together by the girts or

ties

2 ,2, Fig. 10. lVe do not, however, limit ourselves to this precise conformation of parts. Mounted in suitable bearings and in such manner as to admit of the free rotation we provide cylinder 3, Figs. 1, 4, 6, and 10. The drawings show this to be cylindrical in shape; but any other shape might be used. This cylinder should be made of strong and durable material and should be substantially water-tight, having

strong heads

4 and 5, Fig. 6, carefully fitted and secured therein by wellknown methods. Near one end of the cylinder we provide perforated partition 6, Figs. 6, 17, and 18, for admitting the free passage of fluid during the process of washing, as hereinafter more fully described. This partition near one end of the cylinder forms chamber 7, Figs. 6 and 18, into which water, steam, bleach, bluing, or any other mixture or compound, may be poured and mixed with the fluids as they pass through the perforated partition and are brought into contact with the clothing or other articles in the cylinder. It will be readily seen that this chamber is used not only as a means of heating the fluid in the cylinder when steam is admitted thereto, but also affords a ready means of mixing bluing or other substances with the fluids in the cylinder before the same are brought directly into contact with the clothing therein. Inside the cylinder we provide projecting ribs 8, Figs. 6,7 17, and 18, which form a rubbing as well as a lifting surface, by means of which the clothing and fluid are carried up and dropped when the cylinder is rotated, as hereinafter more fully described.

In the walls of the cylinder we provide a hinged door 9, Figs. 0, 10, 14, and 15, hinged to lugs 10 on a frame 11, surrounding the opening in the walls of the cylinder, Figs. 9, 10, 14, and 15. Frame 11, Figs. 10, 14, and 15, surrounds the opening in the cylinder, and is held to the cylinder in a substantial manner by belts or other suitable device for securing the same to the walls of the cylinder in a water-tight manner. This frame has a groove or recess 12, Fig. 14, surrounding the opening. In this groove we preferably provide cork packing 13, Fig. 14, although any other suit able packing may be provided which has some elasticity. The door is provided with a projecting flange or rib 14, Fig. 14, to engage this packing and provide a water-tight joint when the door is tightly closed. For closing and securing the door upon its packing we use the following mechanism: Projecting upwardly from the frame of the door and near each end thereof we provide a wall or ledge of metal 15, Figs. 14 and 15, having projecting inwardly from the upper portion thereof another ledge 10, Figs. 14 and 15, which ledge 16 has its under side formed in a curved or cam-shaped surface. Extending across the door and projecting at each end therefrom an appropriate distance we provide the swinging bar 17, Figs. 14 and 15. This is pivoted at or near its center to the door by pivot 18, Figs. 14 and 15, upon which it (the bar) is free to swing. Fig. 15 shows the door closed and the bar swung into place. It will be observed that as the bar changes to the position shown in Fig. 15 the ends thereof are engaged by the curved under surfaces of projecting ledges 16, Fig. 14, upon the frame at each end of the door, thereby forcing the door upon which the bar is pivoted into close and firm contact with the packing in the recess 12. On the under side of projecting ledge 16 we provide a stop 19, Fig. 14, the purpose of which is to admit of a swinging bar moving in one direction only. Should the swinging bar become accidentally displaced while the machine is in operation great damage might ensue. To obviate the possibility of such an accident we provide the following mechanism: Suitably attached to the outer surfaces of ledge 16, Figs. 14 and 15, and projecting outwardly an appropriate distance therefrom, we provide the flat circular end spring 20 20, Figs. 14 and 15. These springs are so-designed and proportioned that should the swinging bar become accidentally loosened its movement would be arrested before any breakage would occur by its coming in contact with the circular ends of the spring. Then it is desired to open the door, the ends of the springs are lifted and the bar swung under them and out of engagement with the cam-shaped ledges heretofore referred to.

The cylinder is mounted in bearings to be alternately rotated first in one direction and then the other, as hereinafter more fully described. In connection with the bearings of the cylinder there are important features consisting of the central apertures for injecting and extracting bleach, bluing, water, steam, or any other fluid or substances suitable for use in washing clothing or other analogous articles. Bearing 21, Fig. 6, consists of a hollow stud rigidly held to or in the frame of the machine. This stud fits into flanged spider 22, Fig. 6, which is rigidly attached by bolt or rivet 23 23, Fig. 6, to the cylinderhead. The spider rotates with the cylinder on the stationary hollow stud, which extends to the inner surface of the head 5 of the cylinder, or substantially so. To theinner end of this hollow stud forming the bearing, as before described, we attach, preferably, an elbow 24 and extension-pipe 25, opening into chamber 7 of the cylinder preferably at or near its bottom, although this pipe may terminate anywhere within the chamber.

lVhenever it is necessary to have bolts or rivets extending through to the interior of a cylinder, as at 23 and 28, Fig. (3, or to secure the door-frame to the cylinder, we preferably use extra or auxiliary heads 98 98, Fig. 1], which are provided with recesses 99 and 100 for receiving the head and neck of a belt or rivet, as shown in Fig. 1.1. Thishcad we preferably construct of galvanized iron or some non-corrosive metal. It is intended to be sunk wholly or partially in the material of the cylinder. Upon the opposite end of the cylinder we provide a hollow bearing ortrunnion 26, which is preferably constructed in one piece with the spider 27, Figs. 3 and 6, and rigidly held to the head of thecylinder by bolts or rivets 28 28. This bearing is mounted in a box 30 on the frame on antifriction rollers 29, Fig. 3, surrounding the bearing, which rollers are .incased in box 30, Figs. 3 and 6, which box is secured to the frame by flanges 31, Fig. 3. The use of the anti-friction rollers greatly reduces the friction upon the bearing produced by the re versing mechanism hereinafter described. In the outer end of hollow bearing 26, Fig. 3, we provide a circular cup or chamber forthe reception of the flanged nipple 47. Surrounding the nipple is an ordinary packing; gland 48. The annular space between the in: ner end of the gland and the flange upon the inner end of the nipple is used as a chamber for the reception of suitable packing material, as shown at 49. The gland is held in contact with the packing bybolts 5O 50. Attached to the flanged nipple 47 by elbow 96, Figs. 3, 6, and 10, is the pipe 46, Figs. 1, 3, 4, 6, and 10, and this pipe 46, as indicated by dotted lines in Fig. 6 and fulllines in Fig. 10, extends down under the cylinder and up to the hollow bearing 21. The connection of said pipe with said bearing is through the system shown in Fig. 16, and more fully hereinafter described. The hollow hearing atfords with the pipe a means for introducing fluid into the interior of the cylinder. Upon the outer end of the bearing, and preferably constructed as a part of it, we provide pinion 32, Figs'l, 3, aud o.

To accomplish the alternate rotation of our cylinder we providethe following mechanism: W'e mount driving-pinion 33, Fig. 1,rigidly on shaft 34, Figs. 6 and 10, which shaft is mounted on the frame by any wellk11own method, to which shaft power is applied through pulley 35, Figs. 4, 6, and 10, or through pulley 35 and intermediate gear-wheel, as shown at 35 in Fig. 6, or any other suitable device. Pinion 33 meshes into transmittingwheel 36, Figs. 1 and 2, mounted on the frame in suitable manner to be rotated. NVe fix in this tran smitting-wheel, atany point between the center and periphery,..a crank-pin 37, Figs. 1, 6, and 10, which carries connectingrod 38, Figs. 1, 6, and 10, which is attached or pivoted at 39, Fig. 1, to a crank-pin fixed in gear-sector 40, Fig. 1, at any point between bearing 41 of sector, Fig.1, and the periphery of the sector. This gear-sector is mounted on the frame in such manner that it may be alternately swung back and forth around its center and meshes into pinion 32, formed on the end of the hollow bearing 26. By means of this mechanism the continual circular motion produced by the movement in a continuous direction of the transmitting-wheel imparts, through the medium of the connecting-rod and its connection, an oscillating motion to the gear-sector, which reverses its travel each time the connecting-rod passes the two dead-centers, of the transmitter. As the pinion upon one of the trunnions of the cylinder meshes into the gear-teeth on' the sector, it imparts a reversing rotary motionto the cylinder. It will be readily seen that the number of revolutions required for the cylinder to travel before reversing is determined by the relation of the circumference of the pinion 32 to the length of the periphery of the gear-sectors. Thus the cylinder may have one or more alternate revolutions, depending upon the size of the pinion as compared with the size of the gear-sector.

It is quite obvious that considerable strain is put upon transmitting-wheel 36 at the two dead-centers, which has a tendency to cramp or strain the bearing. To overcome these troubles and sec ure'uniform travel of a transmitting-wheel and distribute the strain due to the shifting pressure thereon, we provide wheel-plate 42, Fig. 2, located behind the transmitting-wheel, and which fits over the bearing of the trausmitting-wheel and is bolted rigidly to .the frame of the machine. In the outer edge of this wheel-plate we provide annular groove 43, Fig. 2, which is concentric with the center of the bearing. We also provide in the back of the transmittingwheel annular concentric groove 44, Fig. 2, corresponding in size and shape to that provided in the wheel-plate and being directly opposite thereto. The transmitting-wheel is constructed to run in close contact with the wheel-plate. Between the transmitting-wheel and the wheel-plate, and inclosed in a space formed by the opposing concentric grooves, we provide anti-friction rollers 45, Fig. 2, of suitable size to mechanically fill the two grooves and move therein when power is applied to the transmitting-wheel. By this mechanism the transmitting-wheel may be moved without lateral vibration and the friction reduced to a minimum.

For injecting or ejecting steam, water, alkaline fluids, bleach, bluing, or other fluids or substances suitable to be used in a washin g-machine, into or from the cylinder, either while the cylinder is being rotated or standing still, we employ the system of piping shown in elevation attached to the machine in Fig. 4 and in detail in Fig. 16. Four-way coupling 51, Figs. 4 and 16, is connected at its upper branch by means of proper elbows and nipples to the hollow stud or bearing 21 of the cylinder, as shown in Figs. 4, 6, and 10. The pipe is put together or made up substantially as shown in Figs. 4 and 16.

52, Figs. 4 and 16, shows a three-way cook.

'53 represents an ordinary stopcock, 54 shows an ordinary three-way cock, and 55 represents an ordinary stop-cock. Three-way cook 54 is connected with steam-pipe 56 and controls the same. The steam-pipe is continned each way. from the three-way cock 54 ITO and terminates in contracted nozzles a and 58, that extend into the interior of the modified Ts a?" and 57. It will be observed that the Ts are larger than the steam-pipe, thus leaving annular chambers between the steampipe and the inside of the outer walls of the Ts, into which the steam and fluid enter. Pipe -16, Figs. 1, 4, and 10, connects with a system, as shown in Fig. 16. Pipe 59 is connected with the water-supply. Pipe (30 is connected with the supply-tank containing any fluid, such as bleach or bluing, that may be desirable to introduce into the cylinder of the machine. Pipe 6]. is the discharge or drain pipe leading from the machine. To describe the action of this system of piping, we will assume that the cylinder of the machine is empty and it is desired to fill the same with hot water. In Fig. 16 all cocks are shown closed. lVe turn the handle of three-way cock 52 to the left, which places pipe 59 in communication with the four-way elbow and thus in communication with the inside of the cylinder of the machine. We then turn the handle of three-way cock 54: to the right, which allows steam to issue from nozzle 58 and mingle with inflowing current of water and heat the same to any desired temperature. Should we at the same time wish to introduce fluid from the supply-tank connected with pipe 60, we open cock 53, when the induced current formed by the action of the steam issuing from nozzle 58 causes the same to mingle with the water and enter the cylinder. Should we desire to introduce the water into the cylinder at the end opposite that shown in Fig. 4., we turn handle of three-way cock 52 to the right, when the water passes through pipe 46, hollow bearing 26,'and is discharged into the cylinder.

When we desire to remove the fluid contents of the cylinder, we close cock 53, open cock 55, and turn handle of three-way cook 51 to the left. This admits steam to vertical nozzle a, and as it issues therefrom induces a current that causes the water to flow rom the cylinder through hollow bearing 21 and pipes connected therewith, four-way coupling 51, cock 55, and out through dischargepipe 61. After the flow is established the steam may be shut oif,if desired, when,if the end of the discl1arge-1: ipe G1 is lower than the bottom of the cylinder, the flow will continue until the contents of the cylinder are discharged, the action being that of a siphon. Steam alone may be admitted to the cylinder by turning three-way cock 54 to the right and closing all others, when steam will pass through pipes and hollow bearing 21 and be delivered into the cylinder at or near its bottom and below the surface of its fluid contents.

In this class of washing-machines it is quite desirable to rinse the clothing, after the washing process has been completed, with water, and to have the same delivered on top of the clothing and discharged beneath it, thus securing the washing and rinsing action of the water on its passage through the clothing while the cylinder is in motion. To accomplish this, we open three-way cock 52 to admit the movement of the water from supplypipe 59 toward the right, which passes through pipe 46, discharging the water through hollow bearing 2.6,Fig. 6,into the cylinder, which may be continuallyin motion. For discharging the Water from the cylinder at the bottom we provide aperture (32, Figs. 6 and 19, in the cylinder-head. This aperture should be of suffieient size to allow the free passage of the water, and is alternately opened and closed by valve 63, Figs. 6, 19, and 20,

hinged in a seat suitably constructed in such manner as to open outward and upward, as shown in dotted lines in Fig. 19. On the back of the valve we provide projection or lug (54, Figs. 6, l9, and 20, to which lug we pivot connecting-rod (35, Figs. 6, 8, 19, and 20, which works through bearing 66, which bearing is attached to the head of the cylinder. The connecting-rod has a spur or hearing at its upper end, on which is pivoted roller 67,Figs.

8 and 19, which engages the inner surface of annular ring on movable circle 68, Figs. 5, S, 6, 19, 20, and 21., and is constructed to run on the surface of this circle as the cylinder rotates and in contact therewith. Movable circle 68, Figs. 19, 20, and 21, is mounted upon projecting pins or studs (59, which are firmly attached to the frame of the machine. The circle is provided with projecting cars 7070, Fig. 20, having elongated slots .71 71 therein, which are engaged with the ends of the stud 69 in such manner as to prevent the free vertical movement within certain limits of the movable circle thereon. The outer face of the circle is provided with lugs or cars '72, which furnish a means of attaching the bell-erank-shaped actuating-lever 73 thereto. Roller 67 on the end of connecting-rod 65 is engaged with inner surface of the annular flange surrounding the movable circle, and is held in contact therewith by means of spiral spring 74, or its equivalent, on the connecting-rod. \Vhen the circle is in its normal position, as shown in Fig; 20, it is concentric with the center of the cylinder, and the cylinder with the valve 53 and its attachment are free to rotate without the valve 63 being opened. XVhen the circle by movement of the actuating-lever 73 is moved into the position indicated in dotted lines in Figs. 19 and 20, or any intermediate position, it (the circle) becomes eccentric to the center of the cylinder, and the distance from its lower edge to the lower edge of the cylinder is increased. Consequently rotation of the cylinder and its attached valve 63 must cause the valve 63 to be more or less opened, depending upon the degree of eccentricity of the movable circle. The valve 63 is consequently gradually opened and closed at each revolution or part revolution of the cylinder. I Aetuating-lever at one end to the frame of the machine, the outer or notched end engaging with a proper projection on lever 7 3.

For relieving the cylinder from excessive steam-pressure, we provide aperture 76 in the cylinder-head, of sufficient size to allow the passage of steam. This apertu re is altern ately opened and closed by valve 77, Figs.-5, 6, 19, and 20, which is so constructed as to stop or close said opening. This valve is attached to pivoted lever 78, Figs. 5, 6, 19, and 20, which lever is pivoted in brackets 79, rigidly attached to the cylinder-head, both being constructed to move with the cylinderhead. The end of pivoted lever 78 opposite to the end on which the valve is mounted is constructed to be engaged by, projecting cam 80, Figs. 19,20, and 21,forined on the edge of the circle 68, upon each revolution or part revolution of the cylinder. The cam is curved in form, and is so placed and proportioned as to open the valve when the same is at or near the highest point during the revolution. For keeping't-he valve seated except when opened by the cam, we provide a spring 81 under the end of the pivoted lever opposite that upon which the valve is mounted, which keeps the same closed water-tight, while the end of the valve-lever is out of contact with cam 80.

It is quite obvious that some device should be provided for shifting the belt from the track of theloose pulley which will effectually prevent the belt from being by accident or design shifted to the crank-pulley while the clothing is being removed from the machine and the cylinder at rest. To accomplish this purpose, we employ the following mechanism: Lever 82, Figs. 10, 12, and 13, is suitably connected with a sliding bar 83, Fig. 10, of the belt-shifter at its upper extremity, and is .pivoted at 84, Figs. 12 and 13,to the frame of the machine in such manner as to admit of its free movement within certain limits. e also provide a notched sector 85, which is engaged by an ordinary ducks-bill latch 86, which is attached to lever 82 in the ordinary manner. This furnishes a means for retaining the belt-shifter in certain fixed position. To hold the cylinder in a fixed position, and at the same time guard against the possibility of the belt-shifter being accidentally moved, we provide swinging latch or catch 87. This is pivoted to the frame of the machine at 88 in such manner as to permit its free swinging. This latch has a notch or depression 89 at or near one end, the purpose of which is to engage the pin or lug 90, which is attached to or projects from the end of the cylinder. When the latch is in the position shown in the full line, it locks the cylinder to the frame, and consequently renders it incapable of rotation. 76 also provide lever 82 with a downwardly-projecting lug 91. It will be noticed by reference to Fig. 12 that the latch has what maybe termed a skew-face 92. When the parts are in the position shown in the full line, the edge of the skew-faced latch comes in contact with the lug on the lever and prevents the same being moved to theleft. WV hen the latch is moved by means of handle 93 into the position shown in dotted lines in Fig. 13, the cylinder and lever are released from engagementwith the latch, and they are free, respectively, to be moved as required. For adjusting the belt-shifter we provide a setscrew 95, Fig. 10, in the sliding clasp 9-1, which can be moved along the bar 83 of the beltshifter and adjusted at any desired point by the set-screw 95.

97, Figs. 4 and 7, represents a drip-tank constructed of any suitable material and located under the revolving cylinder, which tank is provided with a suitable waste-pipe.

It is quite obvious that the fluid contents of the cylinder may be emptied by raising the water in the cylinder above the hollow bearing, then opening the stop-cock controlling the discharge-pipe, which discharges below the cylinder, the action being that of an ordinarysiphon; but in order toaccomplish this the pipe connected with the inner end of the hollow bearing must open at or near the bottom of the cylinder.
