IMPROVEMENT IN CAKE-STIRRERS.

Specification forming part of Letters Patent N o. 121,336, dated November 28, 1871.

To all whom it may concern:

Be it known that I, SARAH M. CLARK, of Beaver Dam, in the county of Dodge and State of Wisconsin, have invented a certain Improved Oake- Stirrer 5 and I do hereby declare that the follow-' ing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to improvements in the construction of cake-stirrers 5 and consists in the construction and the arrangement hereinafter described. Y

Figure 1 is a side view of my improved cakestirrer, partly in section and partly in elevation; and Fig. 2 is a top view, also partly in section.

Similar letters of reference indicate corresponding parts.

A is a sheet-metal vessel or cup for holding the dough and other matters to be compounded. It may be of any si'ze or form, and is provided with the metal brackets or ears B B for attachment by screws C to a plate or bar, D, extending over the top, and having at one end the clamping-plate E and screw F for attachment to the edge of a table, shelf, or other suitable support. The barD is slotted at the end, as shown at J, so that on loosening the clamping-screw thereat the latter may be drawn out ofthe slot-also out of the slot in the ear-and thus save the time required to detach it by screwing. It also leaves the bar D free to be moved in such manner as to disconnect it from ear B by drawing the screw out of a slot in the end of it. This arrangement admits of attaching and detaching the vessel readily. Gr is a vertical bar, so attached to the top of bar D and arranged that it will afford a bearing in the horizontal part at the top for the top of the stirrer-shaft H, the lower end of which rests in the step I, in the center of the bottom of the vessel A. The said upright bary G also furnishes a support for the driving-wheel K, which is mounted on the stud L projecting from the side of said upright. M is a pinion mounted on the top of shaft H and gearing with the driving-wheel K, which has a handle or hand-crank for turning, to give motion to the said stirrershaft, on which, within the vessel A, are arranged the concavo-convex arms N, on the outer ends of which are mounted the vertical blades or plates O, also shaped in concavo-convex form. Both the arms and the plates have the large holes P through them, as shown, through which and the spaces between the arms and plates the substance to be stirred or beaten is caused to pass as the said arms and plates are rapidly rotated against it, thereby beating, mixing, and preparing it as is required. The arms of the stirrers may be put on the shaft in sections, so that they may be removed for using more or less as may be required for different substances or quantities. The stirrers may be turned in either direction, as may be required by the nature or condition of the substance under treatment. I may arrange the wheel M at the lower side of the wheel K.

4 Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The vessel A, brackets B, screws C, bars D G E, set-screw F, gear-wheels K M, shaft H, arms N, and vertical plates O, all combined and arranged substantially as specified.

2. The bar D, having the slot J, in combination with the ears B B', also having slots to facilitate the attaching and detaching of the vessel, substantially as specified.

SARAH M. CLARK.
