CHURN ATTACHMENT FOR WASHING MACHINES.

Application led May 28, 1926. Serial No. 112,399.

My invention relates to a churn attachment for washing machines of th e type comprising a vertical standard which drives a dash element for the washer with a partial rotation back and forth iii the washing vessel.

The motion obtainable in Washing machines of this kind is highly suited to the churning of milk, washin and I have conceived that machines of this type can be readily and easily converted to use as a churn by the removal of the dash from the washing vessel and the substitution of a combination churn vessel and dash, the dash element preferably corresponding to the dash of the washing machine but being integral witlr the churn vessel so that the churn attachment can be readily substituted for the dash element of the washing machine and operated within vessel.

More particularly,

the washing my invention contemplates the provision of a churn vessel having its bottom, carrying the dasher elements, surrounding a tubular standard by means of which it is adapted to be mounted on the dash actuating shaft of the washing machine.

My invention further comprises the novel details of construction parts, which will be more fully un and arrangements of derstood by reference to the accompanying drawings and to the description thereof in the following specification and claims.

According to the drawings Fig. 1 illustrates conventionally the type of washing machine with which my invention is adapted for use as an attachment, the churn attachment shown in section.

Fig. 2 is an enlarged perspec churn attachment partly broken tive of the away; and

Fig. 3 is a sectional elevation of the cover for the churn attachment.

Similar reference numerals refer to similar parts throughout the drawings.

In the embodiment of my invention illustrated, I have shown the churn applied as an attachment to a typical washing machine 1,

comprising a dasher standard 2 which, by the washing machine mechanism be shown or described that need not in detail as the same forms no part of my present invention, is

given a partial rotation back and forth about its long axis. In practice the standard 2 is generally it is provided with suitable bear adapted to fit snugly rotated through about 270, and

ings and is within a dash sleeve 3 which is closed overhead and caused to interlock with the shaft by means of a square soclret 4 engaging a square end 5 on the shaft, or .in any other suitable way. This sleeve at its lower end is provided with a circumferential flaring flange 6 which presents an annular concavo-convex face that is traversed by radial fins or dasher blades 7 All of the parts thus far described are standard for the dash of washer machines of the character in question.

To convert this dasher element into a churn, I mount about the outer periphery of the fiange a cylindrical vessel 8 having the depth and capacity designed for the churn, and when the washing machine dasher has thus been converted into a churn it is mounted on the standard 2 and the latter is driven with its partial oscillatory rotation, so that the milk will be caused to surge back and forth about the standard and will be agitated by the vanes so that it will be rapidly ehurned in an efficient and effective manner. After the churning operation, the churn element can be disengaged from the standard 2, and it is of the type which can be readil cleaned and thereafter the standard was er dash without the vessel attachment 8' can be replaced on the standard, thus restoring the machine for washer service.

It is understood that the churn vessel is of a size which can be readily introduced through the top opening 9 in the washing vessel 1 without disturbing the latter.

I provide a suitable lid 10 for closing the top of the churn vessel and which is disposed to clear the top of the sleeve 3 when mounted.

Though I have described with great particularity the details of the embodiment of the invention herein shown, it is not to be construed that I am limited thereto, as changes in arrangement and substitution of equivalents may be made by those skilled in the art without departing from the invention as defined in the appended claims.

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

1. A churn attachment for machines having a partially rotatable oscillatory vertically disposed shaft, which comprises a sleeve ada ted to be mounted for rotation with said sha t, dasher elements secured to the base of said sleeve, and a churning vessel secured to said dasher elements so as to be rotatable with the sleeve, and adapted to hold the milk to be churned in contact with the dasher.

2. A churn attachment for a washing machine having a vertical dasher standard which is partially rotatable back and forth about its vertical axis, comprising a dasher element adapted to be mounted on and driven by said standard and comprising an annular bottom member with dasher blades thereover, and a cylindrical marginal wall rising from the periphery of said bottom and adapted to contain the milk to be churned.

3. As an article of manufacture, a churn comprising a receptacle having a Cylindrical marginal wall, a removable cover, and a bottom; dasher means secured to said receptacle, and a central sleeve rising axially through the churn bottom and having means to couple it to an oscillatory churn-operating standard.

4. A churn according to claim 3, in whichr 6. The combination, with a tub of a washing machine, of a driven shaft projecting upwardly within said tub, and a receptaole positively connected with said shaft so as to be turnable therewith, the weight of said receptacle being borne by said tub at the bot' tom thereof.

7. The combination recited in claim 6, together with a sleeve projecting from the inner surface of the tub and encasing the driven shaft.

8. The combination recited in claim 6, together with a sleeve projecting from the inner surface of the tub and encasing the driven shaft, and means connecting said sleeve with the receptacle, whereby displacement of the receptacle is prevented.

9. The combination with the tub of a washing machine, of a driven shaft projecting upwardly within said tub, and a receptacle positively connected with Said shaft. so as to be turnable therewith, the weight of said receptacle being borne by said tub at the bottom thereof, and a dasher element Within the receptacle.

In testimony whereof I aiix my signature.

CLEVELAND C. KING.
