To all w/wm/ it 1%ar cn0ern:

Be it known that I, WILLIAM H. Voss, 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 Dashers or Stirrer- Heads for Washing-Machines, of which the following is a full, clear, and exact description.

My invention relates to the dashers o'r stirrer-heads of washing-machines; and its object is to make a light, durable, 0 en metal dasher through which the water an suds can easlly percolate, which will not swell or be affected by the swelling of the stirrer-pins or dowels when kept wet for any considerable length of time, and to which said dowels can be readily and securely fastened in proper position, regardless of defects in their manu-. facture, without alteration or removed as desired. This I accomplishby the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 isa vertical central view of the central pprtion of the top or cover of a washing-mac no and the stirrershaft thereof, to which latter my improvements are applied. Fig. 2 is a plan view of my improved dasher. Fig. 3 is a side elevation thereof.

Reference being had to the drawings, A

' represents the top or cover of the tub of a washing-machine, and B the square stirrershaft thereof, journaled in suitable bearin s a in said cover and in an overhead frame substantially as shown. Shaft B has a vertical movement independent of its rotation, and its upper end above. frame I) is provided with a suitable nut or headc to limit its downward movement.

My improved metallic dasher or stirrerhead is secured to the lower end of said stirrer-shaft B and comprises a central boss 0, which has a square opening or socket extending centrally down into it for the reception of the end of the shaft B, to which latter it is secured by a transverse pin or rivet cl. The

I lower closed end of this boss has a concentric disk 6, which has a suitable number of perforations e therein, and has its upper edges f flanged upward. Projecting radially from said edges f are four equidistant corresponding arms, each consisting of parallel side members 9, of the same height as the flanged edges f, the outer ends of which are preferably increased in height and connected by a vertically disposed transverse web h, the outer surfaces of which are concaved to form seats for the shanks F of the wooden dowelor pin G, secured to theouter end of each of said arms. the members 9 are provided with vertical slots 7', that extend down from the upper edges thereof a suitable distance, and when the pins are to be secured in place a bolt D is passed diametrically through a'suitable opening in" their shanks, each. of which has -a nut E on its inner end. The threaded barrels of these bolts are passed into said slits and when said nuts are tightened securely hold the pins G in position. The openings in the shanks ofthe pins through which the bolts are passed are located in the same relative position in each of said pins, and the slits in the end of each arm are of the same depth, so that when the parts of the stirrer-head are assembled the said pins will all be securely fastened in place and extend below the stirrerhead the same distance.

My improved stirrer-head is referably cast in one piece of metal and ena les the water and suds to percolate therethrough without interference, and it is not aflected by the moisture or liable to split when the pins are driven into it, which latter occupy the same relative position to the stirrer-head and can These webs h midway between be readily tightened in lace should they become loose or easily rep aced should come broken.

What I claim as new is 1. A stirrer-head for washing-machines comprising a metal boss, equidistant open arms cast in one piece therewith and projecting therefrom, wooden pins and transverse bolts and nuts by means of which said pins are removably secured to the ends of said arms.

2. A stirrer-head for washing-machines comprising a metalboss having an integral concentric perforate disk the edges of which are flanged upward, equidistant open arms cast in one piece therewith and projecting from the upwardly-flanged edges, and wooden pins removably secured to the ends of said arms. v

8. A stirrer-head for washing-machines comprising avmetal boss having an integral concentric perforate disk the edges of which are flanged upward, equidistant open arms cast in one piece therewith and projecting from the upwardly-flanged edges, and having concave seats in their outer ends, and wooden they be pins secured in the seats in the ends of said arms.

4. A stirrer-head for washing-machines comprising a metal boss having an integral concentric perforate disk the edges of which are flanged upward, equidistant arms each consisting of parallel side members cast in one piece and projecting from said upwardlyflanged edges and having their outer ends connected by a transverse web, the outer surface of which is concaved, and wooden pegs seated and removably secured in the concave ends of said arms.

5. A stirrer-head for washing-machines comprising a metal boss having an integral concentric perforate disk the edges of which are flanged upward, equidistant arms each consisting of parallel side members cast in one piece and projecting from said upwardlyflanged edges, and having their outer ends 4 connected by transverse webswhich latter have a vertical slit therein, and have their outer surfaces concave, wooden pegs, and bolts and nuts for removably securing said pegs in the concave ends of said arms.

6. A stirrer-head for washing-machines comprising a metal boss having an integral concentric perforate disk the edges of which are flanged upward, equidistant open arms cast in one piece therewith and projecting from the upwardly-flanged edges, Wooden pins and transverse bolts and nuts by means of which said pins are removably secured to the ends of said arms.

In testimony whereof I have hereunto set my hand this 6th day of November, 1905.
