struction, arrangement, and combination of,

parts, substantially as will be hereinafter described, and then pointed out in the claims.

In the annexed drawings, illustrating my invention, Figure l is a front elevation of my improved washing-machine arrangedin operative position upon a tub, the latter being shown in section. Fig. 2 is a side elevation of the same, the section of the tub being at right angles to that of Fig. l. Fig. represents enlarged and side plan detail views of one of the clamps for fastening the pitmen to the pounder handles or rods. Fig. 4 is an enlarged detail view of one of the clamps for se'- curing the legs of the frame to the tub. Fig. 5 is a vertical section o f one of the bearingsin which the crank-shaft isjournaled. Fig. 6 is a vertical section of one of the hollow pounders and its hollow handle.

Similar letters of reference denote corresponding parts throughout the several figures.

A represents an ordinary tub.

The frame 0f `my improved washing-machine consists, essentially, of a tripod, which supports the several parts of the invention and is mounted upon the rim of thetub, andwhose legs are adjustable, so that the frame may be suited for connection with any size of tub. This frame comprises two uprights, B B, which are secured together by a horizontal beam, C. To the uprights B B, at points preferably about midway of their height, are hinged the legs D D, and to the bottom ends ofsaid uprights are connected the horizontal arms EE,which pass through slots in the legs D D, said legs being held in the desired position on the arms E E by means of the set-screws e c. A third leg, 5o F, consisting of alongitudinally-slotted bar, is

hinged to the beam O at about midwayof its length, and is normally situated in an inclined position, as shown in Fig. 2. The lower extremities of the legs D D and F are each provided with a clamp constructed substantially in the manner shown in Fig. 4, and consisting of two parallel jaws, one of which, as a', is secured rigidly to the leg, while the other, as a,

is pivotally connected with the leg by pins thereon, which pass through lugs projecting 6o centrally from the jaw on opposite sides ofthe leg, and is adjusted toward or away from the jaw a by meansv of a thumb-screw, b, passing through the jaw a, with its inner end abutting against the leg. rlhe jaws a and a are so formed as to conveniently grasp the rim ofthe tub between them.

I have thus set forth the structure of the frame and the mode of securely fastening the same upon the tub. It now remains to de- 7o scribe the construction of the devices whereby the washing is performed.

A horizontal shaftLG, is journaled below the beam O i`u lbearings that are secured to and supported by said beam. The preferable construction ofthe bearings is .illustrated in Fig.

5, where they are shown as consisting of aV slotted box, H, containing a movable block, d, which is acted upon by a spring, c, so as to be held against the shaft. The shaft is thus 8o permitted to have a certain amount of play vertically whenever the pounders are so iinpeded as to be unable to make their full reciprocation, and the liability of a breakage of the parts is avoided. The shaft G carries a balance-wheel, I, and a pulley, g, and its extremities are provided with the oppositelyextending crank-arms J J, that are pivotally connected with pitmcu K K, whereby `motion is communicated to the pounders. These 9o pounders are arranged alongside of the uprights B B, and reciprocate vertically in this location. They consist of inverted funnet' shaped pieces, L, having a tubular neel: into which is fitted and suitably held-as by asetscrew-a hollow rod, M, closed at its upper eX- tremity by a cap, m. The inner faces of the uprights B B are cach provided with two or more guides, h h, which iuclose the rods M, and thus direct themovelnent of the pounders. roo

The pitmen K K are connected with the rods M by peculiarly-constructed clamps, (shown in detail in Fig. 3,) and adapted to grasp the rods M at any convenient point. They are v4thus capable of adjustment upon the rods M whenever desired. The clamps are constructed as follows: A plate, "i, is arranged parallel to the side of' the pitman at its low'er end and swiveled in said pitman, the swivel being washered on either side of'the pitman. parallel edges of the plate c' are pivoted the jaws kk, whose inner faces are curved semicircularly, sol that the cylindrical rods'M may be held between them. The jaws 7c 7c are caused to grip or relax their hold upon the rod by means of'a thumb-screw, Z.

In order tot revolve the shaft G and actuate the pounders, I find it most convenient to journal a shaft, m, in the slotted leg F, and provide this shaft with va pulley, n, situated Within the slot, and a crankfhandle, o. The pulley n connects with the pulley g by a belt, p, and thus, when the operator of the machines rotates the crank-handle, the shaft'G will be revolved, the pounders reciprocated through the medium of the pitman-connection with shalt G and the-water forced among the clothes, as well as the air which is contained in theinverted funnels and thelhollow rods.

Having thus described my invention, what I claim as new, and desire to sccureby Letters Patent, is-

l. In a washing-machine, the combination of an adjustable tripod-frame, two reciprocating pounders, a horizontal crank-shaft journaled in the frame and actuated by suitable means, and Ypitmanconnections between said shaft and the pounders, substantially as described.

`2.- In a washing-machine, the combination of the frame consisting o't' two uprights connected by a cross beam, the two legs hinged to said uprights and the third leg hinged to the cross-beam,the horizontal crank-shaft j ournaled in bearings carried by the cross-beam, the vertical]y-reciprocating pounders operating in guides upbn the'uprights', ,and suitable connections bet-Ween the pounders and the crank-shaft, together with mechanism for operatng the latter, substantially as described.

3. The combination of the frame, the vertically reciprocating p ounders arranged in guides on dtheframe, the horizontal crankshaft carrying balance-'Wheel and pulley, and its pitman-connections with the pounders, the crank-handle, its sha-ft and pulley, and the beltconnection between the latter pulley and that on the crank-shaft, all arranged substantiallyas described.

4. In a washing-machine, the combination, with the frame composed of cross-beam C and uprights B B, having arms E E, ofthe legs D D, hinged to the uprights B B and clampedto the arms EE.. and the leg F, hinged to the beam C,said three legs being provided with clamps for attachment with the tub, consisting each of a rigid jaw and a`pivoted movable jaw governed by a set-screw, substantially as described.

5. The combination, with the supporting frame-work; of the vertically-reciprocating pounders, the horizontal crankshaft G, journaled in yielding bearings, the pitmen K, connecting with said shaft, and the adjustable clamps for connecting the vpitmen to the pounder-rods, consisting ot the swiveled plates i, curve-faced jaws kk, pivoted thereto,and the 'thumb-screws ,fallarranged substantially as described. y

In testimony whereof I affix my signature in presence of two witnesses.
