ADOLPI-I IVAHLE, OF DAVENPORT, IOWA.
SPECIFICATION forming part of Letters Patent No. 760,500, dated May 24, 1904.
Application filed February 26, 1904. SerialNo. 195, i49. (No model.)
1'0 all whom, it may concern.-
Be it known that I, ADOLPH WAi-ILE, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in stirrer-Heads for Washing- Machines, of which the. following is a full, clear, and exact description.
The obvious object of a washing-machine is to clean clothes, linen, and other textile fabrics, and it should be the aim, although it seldom is, in the domestic washing-machines now in extensive use to reduce the wear and tear of the wash to a minimum. This it is the principal purpose of my invention to accomplish, and this I do by the use of a stirrerhead, which, in addition to its rising or falling to accommodate its position to the quantity of work in the tub as now sought to be done in most of the best machines on the market, presents a smooth and continuous interior to said work and avoids the abrasion and tearing of the same. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.
In the drawings, Figure 1 is a side view of my improved stirrer-head secured to the lower broken-away pendent end of the stirrer-shaft. Fig. 2 is a plan view of the same. Fig. 3 is a transverse central section thereof, taken on dotted line 3 3, Fig. 1, looking in the direction indicated by the arrows.
In the drawings, A represents the pendent end of the stirrer-shaft of a washing-machine, to which a sleeve B is fixedly secured by a transverse pin a. The lower end of this sleeve is'formed into a circular head 6, the diameter of which is slightly greater than that of the remainder of its length, and between this head and its upper end this sleeve has four equidistant longitudinal flanges c 0 c 0 projecting therefrom, the extent of whose projection corresponds to the radius of the circumference of said head. Supported by and slidably mounted on this sleeve B is a tubular boss C, the opening in whose upper end is square Within the circumference of its bore and of such dimensions that the flanges c of the sleeve B enter and move in the angles or corners of said opening; but the boss is pre-v vented from falling off the sleeve by the shoulders of the head between said flanges coming under the undercut shoulders resulting from the squaring of the opening in the upper end of boss 0. At a suitable point between its ends boss C has two lugs (Z (Z, projecting horizontally therefrom diametrically opposite each other, and secured to these lugs (Z (Z by screws and nuts 6 e is the plate D, that has a central opening through which the boss passes and forms the back of the stirrer-head. In order to avoid the shearing strain which would otherwise come on said screws 6, I have provided the boss C where it passes through this plate with vertically-elongated fins f f, that merge 5 into an integral circumferential bead g, surrounding the boss, against which plate I) bears when the screws and nuts 0 are tightened. Plate D may be described as a circular plate having a downwardly-extending outwardly- 7 flaring flange or rim E and having four equidistant tubular sockets F F F F, in which the upper ends of the outwardly-inclined stirring;- pegs G G G G are inserted and secured. Be-
tween these sockets the plate and portions of rim are cut away symmetrically, with the result that the stirrer-head is greatly reduced in weight and improved in appearance.
Inserted within the lower annular edge of the rim E is a circular plate H of wood or 30 other suitable material, which is secured in place by screws h ]t, which latter are tapped through lugs 7r, pro ectlng inward from said rim and into the upper surface of said plate.
In order to give rigidity to the Whole struc- 5 gaging the sides of the depression, substan- 9 tially as shown.
In operation the construction of my invention is such that the surfaces of the stirrer-head brought into operative contact with the work are continuous, unbroken, and
smooth and present no openings or edges that owing to the imperfections of castings or finish (which from a practical standpoint the manufacturer could not afford to give such mechanism) are likely to be more or less rough I00 and likely to catch in and wear and tear the work coming in contact therewith. In addi- 1. The combination with the depending end of a stirrer-shaft, of a stirrer-head slidably mounted upon and supported by said shaft, comprising a plate having a series of equidistant sockets secured to its periphery, pegs inserted and secured in said sockets, and a faceplate secured to said first-mentioned plate within the locus of said pegs.
2. The combination with the depending end of a stirrer-shaft, of a stirrer-head slidably mounted upon and supported by said shaft, and consisting of a plate havinga downwardlyinclined flanged rim, and lugs projecting inwardly from said rim, a series of equidistant sockets secured to said rim, pegs inserted in said sockets, and a face-plate secured within the lower annular edge of said rim, and screws securing the same to said lugs.
3. The combination with the depending end of a stirrer-shaft, of a stirrer-head slidably mounted upon and supported by said shaft, and consisting of a tubular boss, a plate having a central opening therein and secured to said boss and provided with equidistant sockets secured to its periphery, pegs inserted and secured in said sockets, and a face-plate secured to'and beneath said first-mentioned plate within the locus of said pegs.
L. The combination with the depending end of a stirrer-shaft, of a stirrer-headconsisting of a tubular boss slidably mounted upon and supported by said shaft having transverse lugs mediate its ends, a plate having a central opening therein and having a series of equidistant sockets on its periphery, and screws extended through said lugs and into said plate, pegs in- 7 serted in said sockets, and a face-plate secured concentrically to and below said first-men tioned plate.
5. The combination with the depending end of a stirrer-shaft, and a sleeve fixedly secured thereto the lower end of which is provided with a suitable head, of a stirrer-head consisting of a tubular boss the opening in the upper end of which is restricted, and which is supported by, and revolves with buthas a limited vertical movement on said sleeve and has transverse lugs mediate its ends, a plate having a central opening therein and having a series of equidistant sockets on its periphery, and screws extended through said lugs and into said plate, pegs inserted in said sockets.
and a face-plate secured concentrically to and below said first-mentioned plate.
6. The'combination with the depending end of a stirrer-shaft, and a sleeve fixedly secured thereto having an enlarged head on its lower end and provided with a series of longitudinal ribs above said head, of a stirrer-head consisting of a tubular boss the opening in the upper end of which is square within the aircumference of its bore, and which is supported by and revolves with but has a limited vertical movement on said sleeve, a circumferential bead mediate its ends and diametrically opposite lugs projecting therefrom, a plate ADOLPH WAHLE.
