coMBmED Ecc BEATER AND MIXER.

SPECIFICATION lforming part of Lettere Patent No. 664,779, dated December 25, 1900.V

Application filed April 16, 1900.

To @ZZ whom it may concern.'

Be it known that we, ROBERT G. RABIGER and EMIL H. RABIGER, citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in a Combined Egg Beater and Mixer, of which the following is a specification.

One object of our invention is to so construct a beating or mixing device as to effect thorough and rapid agitation of the contents of the vessel containing the material under treatment, further objects being to provide for the ready cleansing of all parts of the beater or vessel, for the ready inserting of the beaters or mixers into and the equally ready removal of said beaters or mixers from the vessel, and the ready setting up or taking apart of the supporting structure, as well as the compact packing of the same for transportation or storage. These objects we attain in the manner hereinafter set forth, ref` erence being had to the accompanying drawings, in which- Figure l is a vertical section of a mixing or beating device in accordance with our invention. Fig. 2 is a sectional View of part of the machine, taken on a line at right angles to Eig. 1. Fig. 3 is a plan view of part of one of the beater-bars and one of the beaters, showing the means employed for connecting the two. Fig. 4 is a side view, partly in section, of that portion of the structure which is represented in Fig. 3. Fig. 5 is a view of the upper portion of the machine, partly in side elevation and partly in transverse section, taken on a line at right angles, to that of Fig. 1; and Fig. 6 is a perspective view of one of the cover-plates of the mixing or beating vessel.

The mixing or beating vessel is represented at 1 and may be composed of sheet metal or of any available material, the upper edge of said vessel being by preference beaded, as shown at 2, so as to form a projecting rib or flange whereby the vessel is supported upon the tops of the posts 3 of the supporting-framework, the vessel being normally confined to these posts by means of the cross-bar4,passin g over the tops of two of the posts, as shown in Fig. 1, and by swinging clips 5, applied to the tops of the other two posts, as shown in Serial No. 13,071. (No model.)

Eig. 2, the latter clips also serving to secure in place the lid 6 of the vessel, which is made in halves, one on each side of the central bar 4, so that either half can be readily removed in order to permit of an inspection of the contents ,of the vessel. Two of the posts 3 have at the top caps 7, which project beyond the posts and form shoulders for engagement with angular clamp-bars 8, through which pass bolts 9, the latter also passing through slots 10 in the cross-bar4 and being provided with lever-nuts 1l, whereby the cross-bar can be securely clamped in place or as readily released when it is desired to remove the cross-bar and the parts carried thereby from the vessel and its supporting-framework. Dowel-pins 12 project upwardly from the cap 7 and enter corresponding openings in the cross-bar 4, so as to hold the same rigidly in its proper transverse position and prevent any twisting or turning of the same on the supporting-frame.

Projecting upwardly from the center of the cross-bar 4 is a rectangular frame 13, and in this frame and in the upturned end 14 of the crossbar 4 are formed bearings for the horizontal driving-shaft 15, which may have an operating-crank 16 or may be provided with suitable belt-pulleys if the device is to be driven by power. The inner-end of the shaft 15 is provided with a bevel-Wheel 1'7, which meshes with two bevel-pinions 18 and 19, the uppermost of these pinions being secured to a vertical shaft 20, and the lower pinion being secured to a sleeve 21, through which said shaft 2O passes, the sleeve having its bearing in the central portion of the cross-bar 4 and the upper end of the shaft 20 having its bearing in v the upper portion of the frame 13. Vhen, therefore, the shaft 15 is turned, the shaft 20 and sleeve 2l will be rotated in opposite directions. The sleeve 2l has secured to it a cross-bar 22, and the outer ends of this cross-bar are provided with depending beaters 23, preferably composed of bent wires, although any desired form of beater may be used. The shaft 2O projects below the sleeve 21 and is likewise provided with a cross-bar 24, having depending beaters 25 at its outer ends, the cross-bar 24 being shorter than the cross-bar 22, so that the beaters 25 will hang IOO down inside ofthe beaters 23 and will approach closely to the center of the vessel l. The heads of the beaters 25 are slotted for the reception of the securing-bolts 26, whereby they are secured to the arms of the cross-bar 24, said bolts being provided with thumbnuts 27, in order that the heads of-the beaters may be readily released from connection with the cross-bar when it is desired to remove the beaters for any purpose. The heads of the beaters 25 are by preference rigidly secured to the cross-bar 24, so that said beaters will occupya fixedpositionin thevessel; but the outer beaters 23 are mounted upon their heads, s as to have a limited amount of swinging motion, whereby when they swing inwardly they will engage the'fbeaters 25, Vand owing to the fact that said beaters 23 and 25 are being carried in opposite directions around a common axis will consequently have a rapid whirling motion imparted to them and when they swing outwardly will' strike the sides of the vessel l, so as Ato scrape 'or clean the same. In order to provide Vfor this limited amount of play yof the outer beaters, each of the latter is provided at its upper end with a ring 28, having a central opening somewhat larger in diameter than the diameter of` the stem 29, which depends from theihead 30, whereby the beater is secured to the cross-bar 22, a washer or other enlargement at the lower end of the stem 29 serving to support the ring 28 vertically thereon. Each ofthe heads 30 is slotted and4 secured to the cross-bar 22 by means of a bolt 31 and thumb-nut 32, as shown in'Figs. 3 and 4. Hence the beaters 23 are removable with the same facility as the beaters25.

lV hen the eggs or other material-to be beaten or mixed have been deposited in the vessel l,

" the latter is applied to the supporting-frame 3, and the cross-bar4 is then secured in place, so as to introduce the beaters into the'vessel and retain the latter in position. The lids 6 are then applied and the shaft 15 rotated, so as to cause rapid rotation in opposite directions around a common axis ot the beaters 23 and`25, thereby subjecting all portions of the material in the vessel l toviolent agitation, which is increased by the whirling motion imparted to the outer beaters 23 whenever the same swing intoengagement'with the innen beaters`25. -Hence the proper beating or mixingof the contents lof the vess'el lcanbeeffected in a much shorter time than with'any other form of vbeater or'mixer w'ithwhich We are familiar. When the operation hasbeen concluded, the cross-bar can be released by removing the clamp-levers lO, andthe beaters can then 'be withdrawn from thevessel and the matter adhering'thereto canbe removed an'd the vessel then taken away to the point at which its contents isy to be.used,'another vesselbeing inserted in its place, and the beating or Vmixingoperation proceeded with as before, so' that the same beating or mixing device can be used with'any desired number of vessels andthe'operationcan be carried on continuously.

The legs 3 of the supporting-framework are braced and held in their proper relative positions by means of rings 33, preferably tubular in cross-sectiomasr shown in Hig.1l,"tl1ese :rings fitting into segmental recesses or seats in the outer sides of the posts and being confined in position by swinging clamps or turnbuckles 34, hung ,to the posts, as shown in Fig. 1. Hence when it is desired to knock down the frame for storage or transportation -the rings can tbe-readily released from con- Vnection with the legs by simply swinging the clamp-levers or turnbuckles out of engaging position.

Having thus described `our invention, we claim Yand 'desire "to secure bydlzetters APatentl. The combination of 'the supportingframework with the vessel havingva-rib vor lange resting thereupon, la rc-ross-bar Whereby said rib lor tlangeisfconned to theY supporting-framework,and clamping devicesffor detachably securing said crossbar in l'posi-V f tion, substantially'as'specilied '2.
