MIXING MECHANISM.

Specification of Letters Patent.

Patented Oct. 5, 1909.

Application filed .April 28, 1908. Serial No. 429,696.

To all whom it may concern.'

Be it known that I, SANNER E. RAY, a citizen of the United States, residing at McConnellsburg, in the county oit Fulton and State ot Pennsylvania, have invented a new and useful Mixing Mechanism, of which the t'ollowing is a specification.

The present invention while relating more particularly to mechanism for kneading dough, is unquestionably useful for mixing, stirring or churning material, particularly that employed tor household or culinary purposes.

The primary object of the invention is to provide a simple and novel structure which can be cheaply constructed, and in which all material will be acted upon, the structure moreover being such that it can be readilyY dismembered for the purpose of cleansing.

rlhe preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a top plan view of the same. Fig. 2 is a vertical longitudinal sectional view therethrough. Fig. 3 is a cross sectional view.

Similar reference numerals designate corresponding` parts in all the tigures ot the drawings.

In the embodiment illustrated, a receptacle is provided comprising end walls 4, side walls 5, and a curved bottom 6, an outer casing 7 being employed for the bottom in order to properly support the said receptacle. The end walls are provided with journal bearings 8 and 9, the bearing 8 having a socket l0 that extends but partially therethrough, while the bearing 9 has an opening 12 entirely through it.

Rotatable stirrer mechanism is employed which includes oppositely extending arms 18 connected by a spiral stirrer blade 14, the

arms and blades being preferably formed of a single rod or bar of metal. One of the arms 13 has an integral outstanding gudgeon 15, which is det-achably journaled in the socket 10 of the bearing 8 while the other arm is provided with a hub 1G having a threaded opening 17 therethrough. A handle crank 18, provided with a hand grip 19, has a gudgeon 2O that detachably passes through the opening 12 in the bearing 9, said gudgeon being provided with a threaded. terminal that screws into the opening 17.

It will be evident, particularly by reterence to Fig. 2 that the arms 13 are disposed in angular relation to the end walls t and thus while said arms rotate adjacent to the end walls, there is considerable space between the same and particularly in the corners formed by the bottom and the end walls not reached by the revolving arms. ln order that the material in such space may be properly stirred and mixed with the main body of the material placed in the receptacle, curved stirring fingers 21 are employed that are carried by the blade 14, and have their free ends operating directly adj acent to the curved bottom and in the spaces formed between the paths of movement of the arms 13 and the end walls. Other oppositely extending and oppositely curved stirring lingers 9.2 are provided that are carried by the blade let and have overlapping paths o; movement in the central portion of the receptacle, these lingers also operating directly adjacent to the bottom G.

`With this construction, the dough or other material placed in the receptacle, will be thoroughly stirred and kneaded when the handle crank is rotated. It will be noted that the lingers 22 continuously move the material toward the center so that it is fully acted upon by the blade let, while the fingers 21, operating in the corners, carry the material out of the same, and thus prevent dry tlour or other substance lodging therein. As a result, experience has demonstrated that with this mechanism, dough or other material can be thoroughly and evenly kneaded or mixed in a comparatively short time. lt will be evident that the structure can be readily and cheaply produced, and moreover it can be easily cleansed, tor if the stirring mechanism is held against movement and the handle crank rotated in a reverse direction to that in which it is rotated when being operated to stir the contents, the gudgeon of said handle crank will be unscrewed from the hub 16, whereupon the stirring mechanism can be removed.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention, will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. or instance while the structure disclosed 1s par- Cil ticularly intended for kneading dough, it will be understood that it can be employed for many analogous purposes, both for mixing and even churning.

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

1. In mixing mechanism of the character set forth, the combination with a receptacle, of a rotary substantially spiral stiriei blade located and extending longitudinally therein, and stirring lingers carried by opposite portions of the blade, said stirring fingers extending towaid each other and having free ends that revolve in overlapping paths of movement.

2. ln mixing mechanism of the character forth, the combination with a receptacle, of a rotary substantially spiral stirrer blade located therein, and curved stirring lingers cari'ied by opposite portions of the blade, said fingers extending toward each other and having free ends that revolve in overlapping paths of movement adjacent to the walls ot' the receptacle.

3. n mixing mechanism of the character set forth, the combination with a receptacle having end walls and a bottom, of rotatable stirring mechanism located in the receptacle and including outstanding arms disposed adjacent but in angular relation to the end walls, a blade connecting the arms, and stir'- ring lingers carried by the stirring mechanism and having their free ends operating in a path between the arms and the end walls.

t.. In mixing mechanism of the character set forth, the combination with a receptacle having end walls and a curved bottom, of rotatable stirring mechanism located therein and including oppositely disposed outstanding arms arranged adjacent but in angular relation to the end walls, a spiral stirring blade connecting the arms, and stirring lingers carried by the blade and having their free ends operating in the space between the end walls and the paths of movement of the arms. i

5. ln mixing mechanism ot the character set forth, the combination with a receptacle having end walls and a curved bottom, of stirring mechanism located in the receptacle f and comprising oppositely extending arms disposed adjacent but in spaced relation to the end walls, a spiral stirring blade connecting the arms, curved oppositely extending stirring fingers carried by the blade and having free ends that operate adjacent to the curved bottom and in overlapping paths of movement, and other curved stirring lingers carried by the blade and having their free ends operating adjacent to the curved bottom and between the end walls and the paths of movement of 'the arms.

G. In mixing mechanism ot the character described, the combination with a receptacle having end walls and a bottom, of rotatable stirring mechanism located therein and including oppositely directed outstanding arms arranged adj acent but in angular relation to the end walls, a spiral stirring blade connecting the arms, and opposite stirring lingers carried by opposite portions of the bla-de, said stirring fingers each extending toward the opposite end wall of the receptacle but outward from the stirring blade, the tree ends of the lingers having overlapping paths of movements.

7. n a stirring mechanism ot the class described, a receptacle having end walls, side walls and a curved bottom, and a rotatable stirrer mounted en the receptacle and cornprising oppositely extending arms adjacent to the end walls, a spiral blade connecting the arms, fingers projecting from opposite portions of the blade and each extending toward the opposite end walls of the receptacle, and opposed fingers projecting from the blade, each extending toward the adjacent end wall ot the receptacle.

In testimony, that I claim the foregoing as my own, l have hereto atlixed my signature in lthe presence oit two witnesses.

SNNER EUGENE RAY.
