SPECIFICATION forming part of Letters Patent no. 608,788, dated August 9, 1898..

Applicatioiiiled Tannery 4,1898.

T0 allwhom it may concern:

Be it known that I, JAMES MOALLIsTER, engineer, a subject of the Queen of Great Britain, residing at Glasgow, in the county of Glasgow, Scotland, have invented certain new and useful Improvements in Washing- Patent in England, No. 15,555, dated June 30, 1897,) of which the following'isa specifi cation. V

My said invention relates to improvements in washing-machines designed both to wash" same receptacle; and the object of the invention is to improve the general construction of the apparatus and increase its efficiency.

The invention is illustrated in the accompanying drawings, in which-- Figure 1 is a vertical section, and Fig. 2 is a plan view, of one form of the machine. In this figure the cover of the casing is removed. Fig. 1 is a detail view of the notched bar of the locking device. Fig. 3 is a front elevation to a reduced scale, showing gearing for driving a machine such as at Fig. 1. Fig. 4 is a part section, and Fig. 5 an inverted sectional plan, of another construction of the machine. Fig. 6 is a sectional view of a third construction of the machine.

On the drawings the same reference-letters wherever repeated indicate the same or similar parts.

The machine shown at Figs. 1, 2, and 3 consists of a casing a, of sheet metal, orit may be a casting, which is provided with a partition Z), so arranged and fitted as to divide the easing into two compartments 0 d of unequal size. Passed up through the partition I) and also through the cover a of the casing is a vertical shaft f. At its lower end the shaft f may work in a foot step-bearing g or other well-known and suitable form of bearing and at its upper end may be passed through a bearing-braoket h, secured to the cover 6. Fitted on the shaft is a rope or belt pulley i, by which it may be driven at ahigh speed from a counter-shaft or a primary shaft.

In Fig. 3 I have shown the pulley i as driven by a rope z" from a pulley j, secured on a short shaft 70, which in turn is driven by s al to. 665,574.. (No model.)

a belt Z from a counter-shaft m, actuated by means of a beltm from any convenient primary driving-shaft.

n n are fast and loose pulleys on the shaft m, which latter is carried in a bearing-socket 0, made in the bracket 19, and in a bearing q,

The pillar has a (1 which carries the is rigidly attached to the bottom of the cylindrical basket t and also to the shaft f. The loose sleeve 5, which extends up through the basket and cover 6 to the bracket h, is provided with gearing by which it can be revolved independently of the shaft f.

In Figs. 1 and 3 I have shown, by way of example, bevel-gearing a a for revolving the sleeve 3. This bevel-gearing is automatically reversed at every few revolutions by means of any suitable and well-known automatic reversing mechanism. In Fig. 3 I have shown a common arrangement of belt-pulley-reversing mechanism mounted on the shaft o,which latter is carried by the bracket-frame p.

The bevel-pinion a can be thrown into and out of gear with the wheel a by means of a lever '11, fulcrumed on the arm n of the bearing-bracket. This lever o is forked at its upper end and acts on a pin a on the sleeve of the bevel-pinion a, which latter slides on the end of the shaft 4) and is guided by means of any wellknown and suitable feather-and groove arrangement.

The sleeve 8 has rigidly secured to it three tubular arms 5. (See also Fig. 2.) Each stirring-arm has vertical uprights s The basket 25 is perforated, as shown at if, all round its sides, and it is provided. at intervals on its inner surface with vertical semicircular or rounded rubbing-tubes t (Shown also in dotted lines at Fig. 2.) The lid or cover of the basket has three openings 25 as shown 5 instead of that shown at Figs. 4: and 5.

w is a water-inlet pipe which is arranged in a circle just underneath the cover (2 of the casing and above the basket. This pipe w is perforated at the parts over the openings 11 so that when rinsing the clothes the water descends in sprays or jets through the openings and 011 top of the clothes. 00 is a drain-pipe for carrying off the water from the space 0, and this pipe, and also the pipe to and the steaminlet pipe a, is provided witha shut-off cock or valve.

The foot step-bearing 9 may be carried by a strong cross-bar 11 secured to the casing a.

In order to lock the basket in position when necessary, a catch of any suitable and wellknown construction is provided. In Fig. 1 I have shown a catch consisting of a lockingpawl 2, which is hinged at its lower end to the block .2 secured to the casing. This pawl is weighted, and when let down (by disengaging the ring 2' of the chain 2 from the catch 2 secured to the cover 6) it automatically looks into a notched or toothed bar ,2, secured to the basket t. This bar is shown in plan view at Fig. 1 and, as will be seen, it is beveled at each end. The ring 2 is sufficiently large to prevent the chain passing through the hole in the cover. I

Figs. 4 and 5 show a modification wherein the sleeve 5 is driven from an automaticallyreversing shaft m, actuated in any well-known and suitable manner, while the basket 25 is rotated by means of a rotary steam or water motor. The fluid under pressure from any suitable and available source of supply passes through the pipe 00 and out at the nozzle 00 From the nozzle the fluid issues with considerable force and strikes against the cups or buckets :0 arranged around the bottom of the basket 25. The buckets, as shown, are made of a hollow wedge shape with their mouths or openings at 00. Any other suitable and well-known form of bucket may be used The use of the rotary-motor arrangement obviates the necessity for driving the shaft f by means of gearing. The waste water from the motor can be drawn off by the pipe 00, while if steam is the fluid used it can be drawn off by a pipe suitably arranged.

In the modification shown at Fig. 6 the driving-gear is arranged below the partition I). In this case the basket t is secured at its upper end by means of the collar t (shown in black) to the shaft f, while the sleeve 8 extends down through the stuffing-box r and has the bevel-wheel u at its lower end. This bevel-wheel is driven by the pinion u of the automatically-reversing driving-shaft 'u in the same manner as set forth in connection with Figs. 1, 2, and 3. The shaft f and basket tare rotated by means of the pulleye' and band 2'', as before. f is a collar on the shaft ffor supporting the sleeve 5. s is a collar on the sleeve 5, which serves as a support for the bottom of the basket '15. The bevel-wheel a is capable of being thrown into and out of gear with the wheel a. The cover is provided with a door 6 .VVith this apparatus after the clothes have been inserted in the basket steam can, as usual, be admitted by the pipe a. The gearing a u can now be put in motion and the arms 3 caused to slowly revolve a number of times in one direction and then a number of times in the opposite direction, so as to thoroughly stir up and circulate the clothes and subject them to the action of the boiling water and steam. \Vhen the clothes have been sufficiently washed, the steam is cut off, and the gearing for driving the shaft 'u is thrown out of action, and the pinion u, is also thrown out of gear with the bevel-wheel u. Thereafter the shaft k is rotated at a high speed in one direction, so as to revolve the shaft f and basket very rapidly, and thereby extract the moisture from the clothes by centrifugal action. The water is allowed to drain away through the pipe 03. During the centrifugal action the arms and sleeve 3 are free to revolve with the basket. During the time the arms are in action the basket tis held stationary by means of the catch.

It is to be understood that I make no claim for the automatic reversing-gear shown on the drawings.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-
