Specification of Letters Patent.

Application filed July 17, 1916. Serial No. 109,743.

To all whom, it may concern:

' Be it known that. I, JOHN HENRY Smnr, a citizen of the United States, residing at Benson, in. the county of Douglas and State of Nebraska,.have invented certain new and useful Improvements in Laundrying-Machines, of which the. following is a speci- 7 fi'cation. I

This invention relates to an improved 1o laundrying machine, and has for its object, broadly, to provide a machine for washing, Timing and wringing clothes, which will be convenient in use and may be conveniently and economically manufactured, the mechanism'and parts to be so arranged that they will occupy, comparatively, a limited space. The invention consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing,-

wherein,

Figure 1 1s a partly broken view of the machine in side elevation. Fig. 2 is a plan view of the same. Fig. 3 is a broken away' viewon an enlarged scale, showing the dasher and vertical dasher shaft and its bearings, the caps for covering-the bushin s being omitted. Fig. 4 is a detail relating 0 Fig. 8, being a plan view of the ratchet to wheel for the dasher shaft, the ends of the trackway for the roller of the crank being in section. Fig. 5 is a broken away detail,

being a plan view showing the arrangement of pinions at or near the upper end of the 35 vertical driving shaft. Fig. dis a bottom larged detail, being a section on'line 7 7 of Fig.1, showing a clutch-controlling device for the shaft of the wringer and means to.

11, and, disposed centrally of andextending vertically above the base and mounted upon member 11 is a tubular standard 12, its lower end being formed as a spider 13 for sustaining stresses directed transversely of the standard and for housing the gear wheel a pinion 25. plan view of the dasher. Fig. 7 is an eni 1 1 of the vertical, hollow driving shaft 15 which is'disposed within the tubular standard 12, said shaft being adapted to be rotated by any suitablemeans, as the worm 16 in engagementwvith the gear wheel 14: and actuated by a motor 17.

Disposed above the base, and mounted to have a horizontal swinging movement on the standard, is a hinge-member 17, its wing 11 being provided with arms 18 and 19, said arms, near their ends, as best shown in Fig.

3, being provided with cylindrical bushings 20 in which the vertically disposed dasher shaft 21 may play, this shaft being angular in cross-section, and the bushings (Fig. 1.) having bearings in caps c which are mounted on the arms 18 and 19 to permit the required rotatable -movements of said shaft and bushings.

Means are provided for causing longitudinal reciprocation and intermittent rotary movements fog the dasher shaft, consisting, in part of a horizontal crank shaft 22 in suitable bearings and carried by the wing a,-its respective ends being provided with a crank 23 and a miter gear 24 The vertical driving shaft 15 is provided near its upper end with a pinion 25. At 27 is indicated a verticalstub shaft having-suitable bearings in and carried by the wing a, its lower end being provided with a miter gear 28 in engagement with the miter gear 24: of shaft 22, its upper end being provided with a pinion 29 in constant engagement with the A coupling member is provided for the d asher shaft21, consisting of a horizontal ,loop or double trackway 30 provided with Patented Mar. 27, 191W.

outwardly projecting arms or supporting- .plates 31 circumscribing thecircular-bushings b with which said arms or plates are provided.- A ratchet wheel 32 is mounted. on the shaft 21 and is disposed between members 31. The end of crank 23 is provided with a tubular pivot-pin 32 (Fig. 1.)

upon which is mounted a roller 33 having .one'of its ends provided with an annular flange, and within said tubular pivot-pin is disposed a pawl or plunger 34 which, normally, projects outwardly of the roller by means of a spring 35.

, As thus described, power being provided by the electrio motor for rotating the worm, the wheel 14 and shaft 15 will be rotated for causing a corresponding movement of the wheel 25. Shaft 27, obviously, will be rotated on account of its pinion 29 being in engagement with said wheel 25, and'on account of the engagement of the miter gear 24 with the miter gear 28, the shaft 22 will be rotated, its crank 23 causing the roller 33 to reciprocate horizontally in the loop or double trackway 30, each rotation of the shaft '22 causing a downward and an upward movement of the dasher shaft, the strokes of saidsha-ft depending upon the length of the crank arm 23; and by referring to Fig. 4 it will be seen that when the roller moves in one direction, the pawl 34 Wlll engage a toothof the ratchet wheel 32 to cause the intermittent movement of the dasher shaft.

In operation, since the rotary movement of the dasher shaft will occur while it is disposed between its uppermost and lowermost )positions, the dasher may be free from the contents of thetub during said movement,'which of course is a desirable feature. 4

The mechanism thus described is of great advantage for washing clothing or other fabrics in conjunction with a dasher 37 which is mounted on the lower end of shaft 21 since the dasher may move downwardly .upon the fabric within the tub m with a deits open, lower end, cross-partitions being provided for each compartment, and suit able apertures 41 also provided so that, dur

ing operation, water or air may pass therethrough.

As described, it may be stated that the vertical, tubular standard 12 operates as a pintle for the hinge member 17, and upon this standard is also mounted, to swing horizontally, a second hinge member 42, its wing 0 having a horizontal extension 43, preferably of angular form in cross-section, to provide a horizontal flange d upon which may be mounted a clothes wringer 44.

Mechanism is provided so that, during operation, clothing or other fabrics may enter from either side of the wringer to pass between the rollers thereof, this often being a matter of convenience since a plu-, rality of tubs" are employed, either for containing rinsing water or for use in connection with the wringer and dasher. Also means are provided so that the wringer and dasher shaft may be operated coincidently or separately. The lower roller 0 of the wringer is provided with a shaft 45 having two miter gears 46 and 47 mounted thereon as idlers, near its inner end. At 48 (Figs. 1. 7.) is indicated a clutch which is feathered on shaft 45, and by means of a hand lever 49 the clutch may be moved on said shaft intoengagement with either of the gears 46 or 47. At 50 is indicated a shaft having bearings in the upper part of the wing 0, its upper end being provided with a pinion 51 constantly in engagement with pinion 26, its lower end being provided with a miter gear 52 in constant engagement with the miter gears 46 and 47.. It will be understood that when a rotation in one direction of the roller 6 of the wringer is desired, the clutch may be moved into engagement with *the gear' 46, and that the roller may be rotated in an opposite direction by moving the clutch H1130 engagement with the gear .47, and the roller 6 will not be rotated if the c 'itch is not engaged by either of these gears.

The pinion 26 is provided with a clutch 69, best shown in Fig. 9, and is also provided with a. pull-rod (Figs. 1. 7. 9.) which is disposed within the hollow shaft 15. The pinion 25 is provided with a recess 71,indicated by broken lines in Fig. 9, the walls of said recess being of such form that, when engaged by the clutch 69, the rotatable movement of the driving shaft 12 and its pinion 25 will be imparted to said pinion 26.

Since the tubs m, g and 2 should be suitably supported and maintained in such positions adjacent to each other as will be convenient for the work of an operator, and since the dasher shaft and wringer should be disposed above and in line with the center of the tubs, the base 10 is provided with radially disposed collapsible frames or supports 53, these being disposed substantially degrees apart. Each frame 53 consists, as best shown in Fig. 2, of aplate 54 provided at its side edges with opposed wings 55 and a narrow shelf or arm 56 hingeably connected at 57 to the inner end of the plate 54, the outer end of the plate having a hingeable connection, as indicated at 58 with the base 11, the free end of the shelf 56 being provided .with a lug or toe-piece 58, each wing also being provided with a lug 59. The shelves 56 may be swung inwardly of the base, when not in use, thelugs 58' engaging in notches or depressions 60 (Fig. 1.) of the base, and when the tubs are disposed on the frames 53, the lugs 58 and '59 will engage their sides near their bottoms as means for holding them upon the frames,

and it will be understood that, by applying a suitable force, the tubs or any one of them, while disposed on said frames, may

be tilted or swung outwardly and partly overturned, this being a matter of great convenience when removing their contents.

As best shown in Fig. 7, the tubular standard 12 is provided with recesses 61 opening on its side, these being disposed 90 degrees apart. The wing 64 is provided with a pin or keeper 62 which is normally pressed toward the standard by means of a spring (33, the movement of the pin being under control of a hand lever 6st, and it will be understood that the hinge member 17 and mechanism carried thereby may be shifted or swung horizontally so that the dasher will be disposed above any of the tubs, the pin 62 entering one of the recesses (31, to maintain the parts stationary.

Also similar means are provided for a control of the hinge member 42 when its wing c has been shifted or swung horizontally. ings in the extension l8 of the wing c. It is normally pressed toward the tubular standard 12 by the spring 66 and is under control of the hand lever 67 for an outward movement, recesses 68, similar to recesses 61 being formed, substantially 90 degrees from each other to open on the side of the standard, in any one of which the rod may engage so that the wringer may be held in stationary position above any one of the tubs.

Since the wringer is used only for limited periods of time compared with the time required'for washing, it is desirable that it be under full, immediate, and convenient control of an operator, and therefore a treadle member is provided for causing operation, or for terminating the movement of the wringer. The pull rod 7 0 is normally pressed upwardly by a spring 72 which is mounted on the bottom of shelf 11 so that the clutch 69 will, normally, be disengaged from the pinion 25, and a downward movement of this rod may be caused by the lever or treadle-arm 7 3 which is pivotally mounted between its ends at 7a upon the lower end of the rod, for use in moving this clutch into engagement wit said pinion 25. One of the ends of the lever 7 3 is provided with a roller 7 5 adapted to bear on the lower side ,of the shelf 11, its opposite end being provided with a foot-piece 76, and it will be understood that the lever 73 may be swung horizontally so that the foot'piece will be disposed .near any one of the tubs so that an operator, by pressing downwardly upon the foot-piece, may cause operation of the wringer, and upon removing said pressure, operation of the wringer will be terminated.

In order that the dasher shaft and washing mechanism will not, be in operation at At 65 is indicated a rod having beartimes when it is desired to use the machine for wringing, the shaft 27 is provided (Fig. 1.) with a clutch 7 7, normally in engagement with the miter gear 28 by means of the spring 78, said clutch being under control of the hand-lever 79.

Having described construction, a further explanation relating to operation is not necessary.
