WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 446,800, dated February 17, 1891.

Application filed October 17, 1890. Serial No. 368,394. (No model.)

T all whom it may concern:

Be it known that I, EDWARD E. UNANGsr,

Va citizen of the United States, residing at Nazareth, in the county of Northampton and State of Pennsylvania, have invented a new and useful VashingMachine, of which the following is a specification.

This invention has relation to washing-machines known as vibratingg and the objects of the invention are to reduce the number of parts and simplify the construction thereof, to increase the durability, and to facilitate the general assemblage of the elements going to make up the completed machine.

Various other objects and advantages of the invention will hereinafter appear;.and the invention consists in certain novel features and combination of parts, hereinafter described, and particularly pointed out in the claims. g

Referring to the drawings, Figure 1 is a plan of a washing-machine constructed in accordance with myinvention. Fig. 2 is a vcrtical longitudinal section on the line :r oc of Fig. 1. Fig. 3 is a detail in perspective of the gear-supportin g standard. Fig. et is a similar view of the leg-connecting frame orbracketfastening. Fig. 5 is a detail in plan of a portion of the rubbingdiead. Fig. G is an enlarged detail in transverse section of the connection between the rubber and the operating mechanism. Fig. 7 is a similar view of the operating-crank and its shaft.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates the usual suds-box, in this instance cylindrical in shape and supported above the ground or floor by the legs 2, located at suitable intervals.

3 designates the leg-supporting frame, cast of malleable iron and comprising opposite vertical side bars et, the lower ends of which are inwardly curved, as at 5, and terminate in laterallydisposed perforated securinglugs 6. The bars i are connected at their lower ends by the t-ransverse keeper-bar 7, at the upper ends of the curved portions by the transverse keeper-bar S, which, as will be seen, is out of vertical alignment with the lower bar 7, and at their upper ends are connected by a transverse socket 9, at'each end of which are located transverse perforated securing lugs or ears 10, similar to thelugs or ears G, and Within the socket is located a pair of inward ly-disposed spurs 11. As thus described, the frame is formed integral or of a single casting, and by means of screws passed through,

the perforated lugs or ears G and 10 said castings are secured to the sides of the suds-box or tub. Previous to such securing the lugs 2 are inserted between the keepers 7 and 8, so that their upper ends rest in the sockets 9, and by a few taps of the hammer or other tool the spurs 11 are driven into the legs near their upper ends, so that after the castings are secured in position the legs are retained therein. By reason of the curving of the lower ends of the bars 4t and a beveling of the upper ends of the legs upon their inner faces said legs are vertically maintained, although, as shown, the sides of the suds-box or tub are inclined. y

The suds-bon is provided with the "usual cover l2, having a central opening 13, to one .edge of which is hinged, as at 15, the lid 14C,

the opposite end of the lid overlapping the cover and provided opposite the center of the opening 13 with a perforation or opening 1G.

17 designates the gear-supporting casting, (best shown in Fig. 3,) and the same consists of a triangular base-plate 1S, provided at its angles with screw-receiving openings 19, and at its widest portion with a vertical standard 20, terminating at its upper end in a transverse bearing-boss 21. At its opposite end the casting is provided with a depending hollow stud 22, which, when the casting is secured in position upon the lid by means of screws or bolts passed through the openings 19 of .its base and the lid, depends throughbelow and snugly fits the opening 16 of the lid. In rear of the casting 17, and in transverse alignment with the bearingA 21 of its vertical standard, there is secured to the lid a standard 23, which at its upper end is provided with a bearing-boss 24, in alignment with the bearingboss 21, just mentioned. A shaft 25 is journaled in the two bearings 21 and 2a and has its ends extending beyond the same, and at its inner end has mounted rigidly thereon a beveled gear 2G. lhc opposite or outer end ol the shalt is beveled or cut away at diametrieally-opposite sides, as

at 27, and its extremity is threaded to receive a nut 2S.

99 designates the operating-handle, and the same is provided at its inner end with a V- shaped rectangular opening adapted to ht the beveled end of the shaft and beheld in 1 o position thereupon by the nut 28. The handle is adapted for oscillation or vibration, and for a purpose hereinafter apparent the shaft Q5 may be given a half-rotation to apply the handle in two opposite positions thereupon.

designates a stub-shaft mounted for rotation in the depending hollow stud The upper end ot the shaft is provided with an integrally-formed small beveled pinion 231, engaged and driven by the gear 20, and at its 2o lower end is provided with a threaded opcning 32. The lower end of the shaft 30 is provided with a reduced bearing tenen or stud 825.

The rubbing-head consists of a metal ring 3i, from the center of which radiates a series 25 of arms or spokes 35, which are connected at their inner ends by a circular-bored hub 3G. The head is formed of cast metal and open, as shown, to secure lightness. At diametrically-opposite sides of the head the arms are 5o provided with elongated openings 3T, in which are secured the upper ends of depending rubbers 3S. As before stated, the hub is eentrally bored, and through the same, from the under side into the shaft 30, is passed the screw 3S). 'lhe reduced end of the shaft 30 passes through and slightly beyond the central perforation of the hub, and said hub is provided with a vertical flange t-O, upon which rests and rides the lower end of the shaft. .lhe to hub is also provided with an annular ilange 4l, which embraces loosely the lower end of the depending hollow stud 22.

The operation of the machine will at once be apparent from the above description, and

it simply requires that the handle 29 should be vibrated back and fortlnso as to partially rotate the gear 26 and wholly rotate the small pinion 3l, which is somewhat less than half the diameter of the gear 2G. This causes a- 5o vibration of the rubbing-head, and the clothing within the tub or suds-box is thoroughly agitated andthe dirt loosened and eradicated therefrom.

It will be observed that it the pinion 3l were not of the relative size stated with regard to the gear 26 one side ot' the shaft i0 and the hollow stud Q2 would receive all or the major portion of the wear and soon became loose and worthless. ly such relative proportion,

6o however, the pinion wears evenly, both as regards its shatt,its teeth, and its bearing. By removing the handle 29 and giving the shaft 25 a half-rotation and reapplying said handle it will be observed that the opposite half ofthe series of teeth et the gearQG are brought into engagement and operation with the pinion, so that the teeth oi the gear are evenly worn and the durability ot i'lie gear increased. It will be observed that the casting 1T and the casting f3, and also the rubbing-head casting, may all be conveniently and cheaply cast and the parts readily assembled without thel necessity of any great amount of labor or the employment ot' a useless number of bolts, screws, the., apt to becolne loosened by the workings ot' the machine. It desired, only two spokes or radiating arms 35 may connect the rim or ring of the rubbing-head with the hub thereof, such being employed forthe purpose of forming a support for the depending rubbers, though I prefer to employ a series of such arms.

ln numerous cases where solid rubbing heads are employed-by which l mean simply one or more radiating bars for supporting the rubbing-pegs or rubbers and unconnected at their outer ends-it has been found that the articles of clothing undergoing the operation of washing ride over the upper sides of the bars and get twisted and caught between the same and the lid, whereby they are torn and rendered useless. l y the employment of the rim, however, I obviate such disadvantage and the ends ot the arms cannot engage with the clothes. Such advantage is further increased by increasing the number of arms, as shown, which further prevents the possibility of the clothing rising or working up inside of the ring, although, as before stated, the ring has been found to answer the purpose.

ll'aving described my invention, what l claim ism l. In a washi11g-machine, the combination, with the side wall thereof, of the herein-described leg-easting, consisting of the opposite vertical side bars 4, the lower ends of which are inwardly curved, as at 5, the keeper-bars 7 and S, arranged out of alignment and connecting the side bars at and above their lower ends, the socket 0, located at the upper end of the casting and having the upper and outer closed sides, the latter upon its inner sufaco having the spurs ll, the opposite pairs of perforated lugs 6 and l0, secured to the wall of the tub, and the legs inserted between the keepers and side bars and having their up per ends terminating in the socket and engaged by the spurs thereof, substantially as specified.

2. In a washing-machine, the combination, with the lid thereof having an opening, of a gear-supportin g casting mounted therein and provided with a depending hollow stud, a master-gear, and means for operating the same supported above the base, a short shaft having a small pinion at its upper end cngaged by said gear mounted in the stud and, terminating immediately below the stud, at which point it is reduced to form a bored interiorly and exteriorly threaded tenen, arubbingdicad comprising radiating arms, a cen IOO IIO
