THOMAS W'. BROWN, OF BELMONT, MASSACHUSETTS.

EGG-BEATER.

SPECIFICATION forming part of Letters Patent No. 419,631, dated January 21, 1890.

' Application filed April 29, 1889. Serial No. 309,110- (No model.)

To all whom it may concern.-

Be it known that I, THOMAS IV. BROWN, of Belmont, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Egg-Beaters, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of my invention is to so improve the construction of that class of egg-beaters which have two revolving beaters that they may be made very light and cheap as well as durable. This object I attain by the mechanism shown in the accompanying drawings, in which- Figure 1 isan elevation of my improved eggbeater- Fig. 2 shows one of the principal details in perspective.; and Figs. 3, 4, an d 5 are enlarged views of details.

By my improved method of construction I am enabled to make the frame of the eggbeater of wire, using a small stiffeningpiece of cast-iron in connection with it.

The frame of my egg-beater is made of bent wire A A A2 A3 A4. This bent wire forms a loop at AA A2, the part A serving as a foot to rest against. the bottom of the vessel in which the substance to be beaten is placed, and the parts A A2 form the uprights to which the wheel-bracket D is connected. This wheelbracket D serves as a firm support for the center pivot M', about which the driving gear-wheel M revolves, and also as a brace and support for the upright A3 A4 of the wire frame. The wire frame and handle A A A2 A8 A4 is made of one piece, the ends meeting at a point within the handle H, Fig. l. The wheel-bracket D is made as shown in Fig. 2, having openings K K cast in it to adm it of the passage of the wire A3. It also has recesses L L', Fig. 2, for securing the wire A4. (See Fig. 1.) The wiresv A3 A4 also pass through a plate P, Figs. l and 5,which holds them irmly and in position to act as axes for the pinions N N to rotate upon. The ends of the wire which form the frame are secured in place at C', Fig. 1, and are also firmly connected by means of the clasp-piece C.

My method of connecting the beaters proper B B is illustrated in Figs. 3, 4, and 5. The openings in the pinions N N are widest at the top, as shown in Figs. 3 and 5. The up* per ends of the beaters are bent to form shoulders or offsets B2 B2, (see Figs. 4 and 5,) and are spread apart when inserted, so as to form a dovetail joint with the pinion. These parts of the beater that form the dovetail have holes Z) b', (see Figs. 3 and 4,) the holes being large enough to receive the wire A, that forms the frame and handle of the machine, and are so located in relation to each part that when the wire is inserted the dovetail lock becomes complete and the beaters are strongly affixed to the pinions N N', as shown in Fig. 5.

To insert the upper ends of the beaters blades into the pinions they are sprung together, as shown in Fig. 4L.

I claiml. In an egg-beater, the combination of the beaters B B and Wire-formed frame-handle having clasppiece O with the wheel-bracket D, having openings K K, receivers L L, and pivot. M', pinions N N', and wheel M, substantiallyv as and for the purpose set forth.

2. In an egg-beater, the combination of a beater-blade provided with offsets B2B'2 at its upper end, bent outward so as to ll the dovetail opening in its pinion, and having holes which register with each other, with its pinion having a dovetail opening, as described, and the upright A2, substantially as and for the purpose set forth.
