RICHARD DANIELS, 0F MILWAUKEE, WISCONSIN.

WASHING-MACHINE.

To all whom it may concern:

Be it known that I, RICHARD DANIELS, a citizen of the United States, and resident of Milwaukee. in the county of Milwaukee and State of \Yisconsin, have invented certain new and useful Improvements in lVashing- Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide a simple, economical and effective washing machine, the construction and arrangement of which is such that it can readily be assembled or dismounted.

lVith the above object in view the invention consists in certain peculiarities of construction and combination of parts as hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings Figure 1 represents a longitudinal sectional view of the machine, the section being indicated by line l1 of Fig. 2; Fig. 2, a detail cross-section of the same, the section being indicated by line 2-2 of Fig. 1, and Fig. 3, a detailed sectional view illustrating means for locking the rotary drum, the section being indicated by line 33 of Fig. 1.

Referring by characters to the drawings, 1, 1, represent uprights that are connected longitudinally by upper and lower sills 2, 2, and transversely by upper and lower sills 3, 3. The uprights and transverse sills 3 are also connected by angle-braces at, whereby the frame members are stifi'ened, the said uprights being also connected intermediate.

of the sills 3, 3, by transverse struts 4 1". As best shown in Fig. 2, the upper frame sills 2 are longitudinally kerfed for the reception of the upper edges of a metallic tank 5, the bottom wall of which is preferably semi-circular in form, the circle being struck from the centers of the transverse struts 4:, l By fitting the upper edges of the tank into the kerfs of the sills, the said tank is thus secured in a simple manner and its upper edges are thereby protected by the sills. The tank is held in its suspended position within the frame by means of longitudinally disposed tie-rods 6, which tie-rods engage the adjacent surface of the curved tank bottom, the center tie-rod being secured to the pair of lower sills 3, while the opposite rods are secured to the sets of angle braces 4. Thus the weight of the tank is supported Specification of Letters Patent.

and the above specific construction, while rendering the frame simple and rigid, also facilitates the assemblage and reduces the cost of manufacture. The mouth of the tank is inclosed by longitudinally arranged panels 7, 7, and the panel 7 has hinged thereto a lid 7", whereby the closure is completed, the lid being provided for access to the interior of the tank.

By employing top panels as shown and connecting them with the upper corner sills, a tight joint is formed at these corners of the tank and the tendency of accumulated water at the corners through sloshing to leak therethrough is avoided, attention being called to the fact that the joints between the lid and the panels being at an intermediate point will have slight tendency to leak due to the action of the water in traveling over the uninterrupted surface. A further advantage of the construction described is the fact that the tank, in connection with its side walls and heads is of suflicient depth as to practically submerge a washing drum, to be hereinafter described, whereby the maximum etficiency in the washing operation is obtained.

In washing machines of the type to which my invention refers, so far as I am aware, the tanks are usually halved or divided upon the axis of oscillation of the rotary drum mounted therein and hence leakage at the joints is such that only a small quantity of water can be utilized.

Revolubly mounted within the tank is a skeleton drum A, which drum is composed of a pair of circular heads 8, 8, the same being connected by spindles 9 that are circular in cross-section, the said spindles being secured by wood screws 9 that pass through the drum-heads and enter the spindle ends, an auxiliary securing means being employed in the form of nails or spikes to prevent the spindles from turning. These spindles are, as shown, preferably spaced apart to permit the flow of water therebetween, it being understood that the tank is filled with water in a washing operation, which water may be at any desired temperature and is drained from the tank when not in use through a drip-cock 10 with which the bottom of the tank is provided. Each drum-head is provided with a series of radially disposed fins 11 that serve to assist in revolving the material to be washed that is held within the drum and also serve to agitate the water.

The drum- heads 8 and 8 are also provided with separable drum-head sections 12 which complete the circular contour of said drums and are each connected to the main portion of the same by means of hinges 18. These drum-head sections are longitudinally connected by spindles 9", which spindles are secured in a manner similar to that described in connection with the spindles 9 and serve to complete the skeleton surface of the drum when the hinged section is closed, as best shown in Fig. 2. The hinged section 12 is locked in its closed position by buttons 13 that are swiveled upon plates 13, which plates are secured to a pair of the drum spindles 9, the buttons being adapted to engage hasp members 14 that ex tend from plates which are secured to the juxtaposed pair of spindles 9 that are carried by the hinged section adjacent to its free end.

The transverse strut 1 of the frame is provided with an apertured journal-box15, into which aperture is fitted a stud 15' that projects from the center of the drum-head 8. The opposite drum-head 8 is provided with a centrally disposed apertured hub 16, into which hub is fitted the end of a studshaft 17. The stud-shaft 17 is mounted in a journal-box 18 that forms part of the transverse strut 1 the said journal-box being provided with a gland 18 which extends through an aperture formed in the end wall of the tank, whereby a tight joint is effected, it being understood that the journal-box 15 also projects through an aperture in the opposite wall of said tank, as shown. Loosely mounted upon the stud-shaft, between the journalbox gland 18 and the hub 16 of the juxtaposed drum-head, is a spacing-collar 19, the same being provided to prevent end play of the stud-shaft, which stud-shaft is arranged to be removed through the gland and j ournal-box, whereby the drum in its entirety can be lifted from the tank. In hanging the drum in its position, it is apparent that the trunnion stud 15 is first fitted into the apertured hub 15 and thereafter the. stud-shaft 17 is inserted through the box, whereby its end is passed through the loose collar and is then socketed into the drumhead, being locked to said drum-head by a set-screw 16, which set-screw is in threaded union with the hub. Secured to the outer end of the stud-shaft is a gear-wheel 20, which gear-wheel meshes with apinion 20 that is carried by a flywheel 21, the same,

together with the pinion, being loosely mounted upon a stud 22 that is carried by the strut 4E By this gear connection power is applied to the drum, whereby the same is rotated, the fiy-wheel being provided with a handle for the application of manual power to the driving gear. It should be understood, however, that I may utilize any inotive force for rotating the drum, which force may be applied to the face of the fly-wheel by means of a belt,

In order to lock the drum against rotation and in such position that its door or hinged section 12 will be alined with the lid 7 of the tank, I provide a gravity dog 28, a nose of which dog is adapted to engage a notch 23 that is formed in the hub of the gearwheel 20. Hence when the drum is locked in the position shown in Fig. 2 the lid 7 is first opened and thereafter the hinged section of the skeleton drum is also swung open, whereby access is had to the interior of the drum. The clothing or other articles to be washed are then inserted through the open mouth of the drum to its interior. The drum-section is then closed and locked, together with the lid of the tank, it being understood that the said tank is filled to the desired level with water. The gravity dog is then disengaged from the notched hub of the gear-wheel 20, being swung to a disengaging position about its pivot, in which in-- operative position it is held by gravity. The washing operation is effected by rotating the 'drum in the ordinary manner. This rotation of the drum causes the articles being cleansed to shift back and forth in their confined position and, co-incident to this shifting water is permitted to freely flow between the spindles, whereby a strong current is effected to thoroughly cleanse the articles, the said articles being also shifted by the fins or flanges 11 that extend inwardly from the drum heads. It is further apparent that in rotating the drum the articles therein will not be torn or damaged due to contact with the spindles owing to the fact that said spindles are circular in cross section, the clothing being at all times in contact with rounded or fiat surfaces, the fins, as shown, being semi-circular in cross-section.

From the foregoing description it is obvious that when the tank is closed there are no crevices at the ends or top through which water is liable to seep caused through the rotation of the drum and it is also manifest that the drum can readily be removed or inserted within the tank from above the coupling connections previously described in connection with the drive-shaft and, when so fitted, the drum is held against lateral play due to the interposition of the collar 19.

I claim:

A washing machine comprising a skeleton frame provided with end uprights and upper and lower sills connecting the uprights, the upper sills being longitudinally kerfed, a semi-circular bottom tank having apertured end heads fitted within the skeleton frame the top side-wall edges of the tank being embedded within the upper sill kerfs, panels secured to the upper sills and extending inwardly therefrom at predetermined dis- In testimony that I claim the foregoing I 10 tances to form an opening in the top of the have hereunto set my hand at Milwaukee in tank, a lid for said opening, horizontally the county of Milwaukee and State of i:- ilispolsed tie-rods fo'ming plottom support; cousin in the presence of two witnesses.
