MECHANICAL MOVEMENT FOB- LAUNDRY-WRINGEBS.

Original application filed June 20, 1913, Serial No. 774,747.

Serial No. 806,165.

To all whom it may concern:

Be it lgnown that I, SAMUEL T. Warm, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Mechanical Movements for Laundry-Wringers, of which the following is a full, clear, and exact description.

My invention relates to mechanical movements particularly adapted to laundry apparatus, and more particularly to the wringer actuating mechanism of domestic washing machines in which the wringer is driven from the same source of power that drives the washer.

The principal object of my invention is to provide simple and effective mechanism that will drive the Wringer in one direction or the other simply by shifting a connecting lever.

Another object of said invention is to enable the operator to release the driving mechanism from the washer by suitable means that may be manipulated by him, either in front or in the rear of the machine, to shift said driving mechanism so that it will operate the wringer mechanism and revolve the same in whichever direction it is desired to have the roller turn.

These and other objects I accomplish by the means and in the manner hereinafter fully described and as more particularly pointed out in 'the claims, reference being had to the accompanying drawings forming a part of this specification, in which- Figure 1 is an end elevation of my improved mechanical movement, showing the same applied to the frame of a cylinder washing machine. Fig. 2 is a side elevation of the end portion of the machine to which my improvements are applied. Fig. 3 is a horizontal section taken on line 33, Fig.

i 1 of the end of the machine to which my improvements are applied. Fig. 4 is a horizontal section of said end portion of the machine taken on line 4-4, Fig. 1. Fig. 5 is an enlarged detail view of one of the elements used in shifting the wringer actuating gears. Fig. 6 is an enlarged detail view Specification of Letters Patent.

Showingthe wringer driving gears in one position in full lines, and in a reversing position in dotted lines. Fig. 7 is an enlarged detail view of a modified arrangement of the gearing employed in my improved mechanism.

The supporting frame-work of my improved mechanism is so constructed as to support the cylindrical casing C within which the horizontally disposed rotaryreciprocable cylinder A is inclosed, and so as to support the actuating mechanism therefor that is situated at one end of the machine. This frame-Work includes comerposts or legs B that are, preferably, mounted on suitable. casters to enable the machine to be rolled with ease, and with suitable longitudinal rails B connecting said legs near their lower ends, and suitable cross-bars connecting said rails near their ends, and it is so constructed as to provide a platform upon which the motor 1 and gearing are mounted for transmitting the motion to the actuating mechanism. This supportingframe of the machine also includes a rectangular frame secured to the upper end of the legs, to which the casing C isimmediately attached, and the end piece C of this rectangular frame, at one end of the machine, is connected with a crossbar B by a metallic standard B.

The mechanism for actuating this cylinder A is fully disclosed in and forms the subject-matter of an a plication 'for Letters Patent of the United States filed by me June 20, 1913, Serial No. 774,747, for im: provements in mechanical movements for washing machines, of which this application is a division, and, therefore,,need not be described in detail herein. Suiiice it to state, however, that this actuating mechanism comprises a "ertically disposed longitudinally reciprocable rack- 14 that engages' a pinion 15 on the outer extended end of the journal a of said cylinder, which rack is slidably mounted in a vertical casing or guide-frame 13 that is pivoted at its lower end on the standard B. Rack 14 is moved up and down by means of a pitman 17 the lower end of which crank-pin 18 of a large gear 10, Which latter is actuated by a pinion9 on the outer end of a spindle 7. A large gear 6 is secured tothe inner end of spindle 7 and is engaged by a pinion 5 fast on the outer end of a suitable shaft that is driven through the medium of a pulley 2 that is connected by a strap or belt 3 to the motor 1. Whenever it is desired to disengage rack l4 from pinion 15 one or the other of horizontally disposed levers 19 and 20 is depressed, and, through the medium of links 22 and 23, will move the casing or frame 13 laterally on its pivot sufliciently to disengage the parts mentioned.

Washing machines of the character to -which my improvements are applied, as well as other types of laundry apparatus, require the use of wringer mechanism in connection therewith and are not considered complete without the same. For this reasoii it is necessary to provide s 'ichwritiger mechanism aiid means for actuating the same so that the rollers thereof can be moved either in one direction or the other or can be thrown out of erigageineiit withthc actuatihgiiiechanisni of the machine ehtirely, accordingly as desired. In order to accomplish this result (ivhichis' one of the objects of my invention), I inount upon a ho rizoiitally dis posed shaft 24, substantially parallel with the shaft ofpulley 2, a small pinion 25, and on the outerext'ended end of said shaft a bevel or miter gear '26 is mounted that mesheswith a beveled gear 27aiid is at sub- Stfilltliilly right angles thereto. This miter gear 27 is fast on thelower end of a vertically disposed drive-shaft 28 for actiiating the wringer 29 mounted on the upperedge of the end piece of frame C. In oraertoaecoiiiplish this the upper end of shaft 28, is provided with a mitei gear. 30, the latter meshes with a miter gear 31 V extended end of theshaftof the diiyeroller 32 of the wringer 29. Gcars 30 and 31 are, preferably, surrounded and protected by a hemi-spherical shell or casing 33 having bearings 34 and 35 for both shafts 32 and 28, as Q D- f Between gear 25 and beveled pinion 26,

shaft 2 4 has a substantially triangular shaped bracket 37 pivoted thereon which is provided with two inwardly projecting stiids 38 and 39 on which suitable gears 40 and41 are mounted that .mesh with each other. When pivotal bracket 37 is moved downward sufficiently, gear 41 will mesh with a drive-pinion 8, mounted on spindle 7 between gears 9' and 6, and through the medium of gear 40 transmits motion to the pinion 25. \Vhen this bracket is raised sufficiently, gear 40 will come into mesh with drive-gear 8 and will directly drive the pinis pivoted upon the mounted on the ion 25 in a reverse direction. In order to facilitate the changing of these gears and reverse the motion of the \vringer mechanism, I provide a vertically disposed rod 42 which at its lower end is pivotally connected to bracket 37, and at its upper end is pivot ally connected to the outer end of an arm 43 secured to a horizontally disposed rock-shaft 44. This rock-shaft is mounted in bearings 45 secured to and projecting from the ends of frame 0, and where said shaft extends beyond these bearings, it is provided with suitable vertically disposed handles or levers 16, the turning of which in one direction or the other rocks shaft 44, so as to raise or lowerrod and swing bracket 37 and cause gear 40hr 41 to engage. gear 8. When at the limit of its raised or lowered position, the arm 43, to the outer end of which rod 42 is pivoted, will be on a dead center, as shoivii in dotted lines in Fig. 9 of the drawings, and when said bracket is in a horizontal position, as shown in full lines in said figure, the gear will be disengaged.

Fig. 7 of the drawings shows a slightly modified arrangement of the gearing emlayed to reverse the wiinger, in which the shiftiiig of a single gear is used instead of two gears. This modification comprises a pulley50 corresponding to pulley 2 in the preferred form, and gears 51 and 52 correthe preferred form. A pin on 53 is mounted on theeiid of the pulley-shaft and pinions 54 were secured to the outer end of the spindle fifi Pinion 53 derives its motion from said pulley-shaft and drives the large gearol mounted on one end of spindle 56, which latter, through .the medium of pinion 549a its opposite end, transmits motion to said large gear 52. Pinion 55 is, preferably, in mesh with and drives a pair of idle pinions 5 8 a'hd 59 that are mounted upon suitto aiid projecting lat spoiidiii'g, respectively, to gears 6 and 10 in able spindles secured erally from the adjacent portion of the platform or crossbar 60 of the sup orting frame ofthe machine. Pinions 55 and 59 are arranged with their axes in substantially the same vertical plane, .while the axis of pinion 58 is slightly to one side thereof. Located immediately above and with its axis in substantially the same vertical plane with pinion 58 is a supplemental pinion 61, that meshes with and derives its motion from pinion 59. All the pinions just mentioned, (Le. 55, 58, 59 and Gl) are of substantially the same diameter and pitch, and are so ar ranged that their axes substantially form four corners of an imaginary hexagonal figure.

Mounted on the outer end of a longitudinally disposed shaft 62 is a beveled pinion (not shown) that corresponds to the beveled pinion 26 in the preferred form, through the medium of which the wringer is drivenyand adjacent thereto a pinion 68 is mounted on said shaft. Between gear 62 and said omitted beveled pinion, shaft 62 has a suitable elongated bracket 64'pivoted thereon which is provided with a laterally projecting stud 65 on which a shiftable gear 66 is mounted in mesh with pinion 63. When this bracket is moved'upwardly or downwardly sufficiently, the gear 66 will be brought into mesh with either pinion 61 'or pinion 58, according to the direction in which it moves, and through the medium of pinion 63 will drive the wringer mechanism either forward or reversed, as the case may be. Bracket 6% of this modification is moved by a rod 67, similar in construction and operation to rod 42 of the preferred form.
