This small and simple piece of apparatus, designed to aid the housewife and pastry-cook, can be made of any material or shape, and is always ready to do its work quickly and well. In our illustration, A is an ordinary tin, Britannia metal, silver, glass or china vessel, having a small socket, a, soldered in the center of its base ; in this rests the spindle, B, of any unoxydizable metal, having cast on its lower part the grating, b. This spindle is square at the top, and a thick india-rubber band, C, passes round it. D is a metallic brace, the hooks at the extremi ties of which pass around the rim of the vessel and hold the spindle, B, firmly in its place, free to rotate in the socket, a, and another one at the top of D, but not capable of shaking up and down ; between an angularity on D, and the friction-band, C, there is a bar, E, by moving which backwards and forwards, a rotary motion is given to the spindle and grating, b. It will be seen that the vessel is provided with two lips which retreat enough to admit of D being turned round and lifted off or on with ease and facility. The process of egg-beating is a tiresome one; and many a cook, with aching wrist, will be glad to hear of thrs invention, which will beat six eggs in ten seconds. All that has to be done is to break the eggs into the vessel, draw the bar, E, backward s and forwards a few times, and the grating, b, from its shape, so thoroughly breaks up all portions of the eggs that they must be well and perfectly beaten. It will also whip cream and mix essences and ingredients for cooking equally and with speed, and from the simpli- city and fewness of its parts, it can easily be kept clean. Another valuable use to which t can be put is that of churning, as from the shape of the grating, it effects the desired object (that of breaking up the milk or cream and uniting the particles of butter) much quicker and with more economy than the nolid dasher ; and as it has a reversible motion, the breaking-up effect of the opposite currents aids the formation of the butter. It can be used as an ice-cream freezer by merely placing it in a bucket of ice when, by moving E, the cream will be agitated and thrown in small particles against the cold surface, sind quickly moved away, and other particles thrown against it; and as motion will be kept tip during the whole time of freezing, there ?vill be no lumps in the ice-cream. To all these uses and some more, can it be put with-without changing any of its parts or making the slightest alteration in their arrangement; so that it is one of the most useful and compact aids to domestic economy that we have ever seen, and can be made of any size from one quart to five gallons. It is the invention of John B. Heich, of Cincinnati, Ohio, and was patented by him Dec. 15, 1857. He has assigned part of the invention to Richard E. Heich. and any further information respecting rights or the apparatus can be had by addressing Heich & Brother, Mechanics' Institute, Cincinnati, 0. See their advertisement in another column.
