JOHN W. SEIFERT, OF ST. LOUIS, MISSOURI.
WASHIN G-M ACHINE Application filed December 28, 1907.
T o all whom it may concern:
Be it known that I, JOHN WV. SEIFERT, a citizen of the United States, and resident ot' St. Louis, in the State of Missouri, have invented certa-in new and useful Improvements in fashing-h/Iachines, of which the following is 'a specitication.
My present invention is an improvement in the class of boiler Washing machines,l and particularly upon the machine forming the subject of my United States Patent, No. 850,061, dated April `9th, 1907, and No. 880,334, dated Feb. 25, 1908.
rIhe details of construction, arrangement; and combination oit' parts embodying the invention are hereinafter described, and illustrated in the accompanying drawings in which- Figure 1 is a perspective view of the may chine. Fig. 2 is a perspective view showing the cover thrown back and the clothes-drum in the position to which it is raised.. or elevated, when it is required to discharge clothes therefrom. Fig. 3 is a vertical section of the machine, the clothes-drum being shown in end view. Fig. 1 is a rear view of the upper portion of the machine. Fig. 5 is a vertical section on the line 5 5 of Fig. 3. Fig. 6 is an enlarged side view of a portion of the machine, particularly the levers and gearing by which the clothes-drum is operated and raised to anjelevated position, the handle socket being shown in section. Fig. 7 is a reduced perspective view of the side of the machine opposite that shown in Fig. 6. Fig. 8 is a. vertical section on the line 8-8 of Fig. 6. Fig. 9 is a perspective view of the pivot end of one of the levers in which the clothes-drum is journaled. Fig. 10 is a perspective view of the handle socket and the sprocket wheel attached thereto.
'Ihe body A of the machine is constructed of sheet metal and rectangular in form. Within the body is arranged a fuel grate a and below it is an ash pan a. Above the grate kettle, or boiler proper, B, whose upper edge is constructed with anges or hooks adapted to rest upon the top edge of the body A.
A is a semi-circular cover whose lower portion is square and provided with an internal flange adapted to enter the upper'edge of thekettle B, as shown in Fig. 3. In the space inclosed between the kettle B and the y* cover A is arranged a cylindrical clothes- Speceaton ofLetters Patent.

drum C, the same being provided with trunnions o, c', that constitute journals in the ends of the longer arms of levers D, D, arranged parallel on opposite sides of the machine and journaled, or pivoted, on a shaft D2 that passes through the upper front cor ners of the body A. A sprocket wheel Eis clamped on the trunnion c of the clothes-A drum and a chain F runs thereon and on a small sprocket E, which, as shown in Figs. 8 and. 10, is formed integral, with or rigidly connected, with a sleeve e having a handlesocket G cast integral therewith. These parts, F/ and c, are adapted to lrevolve loosely on the shaft D2.
The handle H is held detachably in the socket G by means of a spring catch lq--see Figs. 6 and 10. It is apparentthat, by inserting the handle H in the socket G and rotating the same, the small sprocket wheel E will be rotated also, and thereby, through the chain F, like motion will be imparted to the sprocket wheel E and the clothes drum C so that the latter will be caused to rotate in the hot water in the boiler B. The proportion between sprocket wheels E and E is preferably such that three revolutions of the wheel E are required to produce one revolution of the wheel E, so that the travel of the clothes-drum is comparatively slow.
When it is desired to remove the clothes from the drum, the handle H is removed from the socket Gr and inserted in the same way in a socket D3, which is formed integral with, and as a lateral projection on the upper side of, the lever D, at a point directly op posite the pivot shaft D2. Then, by using the handle H as a lever, and forcing -it outwardly and downwardly to the position indicated in Fig. 2, the clothes-drum will be raised out of the boiler or kettle and will overhang the front edge of the boiler and the body A, so that the clothes will discharge through the opening and will be guided in their descent by the curved door c3 into a receptacle, which, as indicated by dotted lines,
Fig. 2, may be the inverted cover-A of the the proper angle, as indicated by dotted lines, Fig. 6 and full lines Fig. 2. The said lugs are also located in the right position for contact with, and arrest of, the levers D, D, when the drum is lowered into the kettle B. Spiral springs J-see Figs. 1, 2l
and 3are connected with the shorter arms of the levers D, D, and with hooks a? secured to the body A. These springs are of such length that when the drum C is neither of its two positions, the springs are under tension, or stretched. This tension is not suflicientto exactly balance the weight of the empty drum and its attachments, but it is sufficient to prevent thelevers D, D, from striking heavily on the stops I when the loaded drum is lowered into the kettle or when raised to the elevated position; and they'4 assist materially in raising the loaded drum out of the kettle. Hence, in ,consel quence ofl the attachment and tension of the springs J, the loaded drum C may be raised andlowered much more quickly than would be otherwise practicable.
. In Fig. '2 the full lines show. the cover A supported in a nearly vertical position, and dotted lines Fig. 3 also illustrate the same. The means for supporting it in this position are indicated in Figs. 3 and 4, and consist of a plate K hinged to the cover atand provided near its lower end with a recess, or groove, k. A form of support L adapted to `engage the notch, or groove, Zr: of plate K is attached to the side of the body A and its upper end projects laterally as shown. When the cover A is raised and thrown back, the plate K and the support L engage, as shown by dotted lines Fig. 3, the cover being thus supported in a position slightly inclined from the vertical. l/Vhen the cover is drawn forward and downward, the hinged plate drops back and automatically disengages itself froml the support L. Thus the engagement and disengagement are both automatic, it being only necessary to raisethe cover or lower the same in order to effect these operations.
Within the body A and on opposite sides l of the bottom of the kettle B, I arrange guard plates M, M, which prevent access `of flame andheated gases to the upper portions of the kettle and direct them toward the exit where the pipe N is attached to the body A. As shown in Fig. 5, vertical guard plates O are arranged on opposite sides of the grate a to direct the flame and heated gases upon the bottom proper of the kettle, rather than permit them free access to the upper portion of the kettle.
It will be seen that the several guards prevent direct access of llame and heated gases to the upper portion ofthe body A and practically conne them to the space above the grate which iscovered by the bottom ofl the kettle B.
I claim: y y The combination with the body of the ma.-
chine, and a kettle supported therein, of a reticulated closed drum, parallel levers in which said drum is journaled, a shaft the ends of which extend from the body at the front upper corners of the same, to serve as the pivots of the levers, a sprocket wheel ixed on one of-.fthe drum pivots, another sprocket wheel mounted loose on one of the lever-pivots and provided with a rigid handle socket, and a chain applied to and connecting the two sprocket wheels, as shown and described.
