.-Bejitknown that I, WALTER MA'rrnns, al subject of the Emperor vof Germany, re-

siding at Austin, 1in the county `of Travis:

and Sta'te Eefer Texas,` yhave 'invented' certain new and useful-"Improvements in Gifting- Machines; and YI do hereby declare `the fol-.flowingto Ibe a'full,1clear,1and exact descrip-y tion- 'of Athe invention, such as willA enable othersiskilled n the art to which it apper-y -l tainsfto vmake andfuse the' same.v

`lhis inventionrelates to asifting machine' especially adapted for sifting flour, meal or the" like Aafter' thel initial 1 treatment 'fof the grain to separate foreign yand other material fromrthe flour,-meal or thelike. A v 1 Another object' of this invention is to provideachamberwithin a casing Ato receive the material or crushed grain after the initial treatment and is yadapted to be thrown f against'a screen, whereby theiour, meal or f novel features 'of construction, combination' lowing description the likewill pass through the screen and' be separated from the refuse. l

fA'ifurther object' of this invention is to providey ajnovel g form lof agitator having meansfo'r agitating the material or crushed grain' alongthe' entlre lengthof the agitator, Sfothatthematerial or crushed grain will be equally distributed7 -whereby all ofthe material'fwillnot be thrown against rone point of l'Arfstill further objectof this invention is theY provision 'of a sifting machine `of `the above stated characten which shall be simple, durable `and efficient, Vand `which may lowcost. A e a ,'Withthese and] other objects in view-'as willf become'more apparent as the description proceeds, the invention consists fin certain and'arrangement 4of parts as will'be herein after more-fully describeda and claimed; For a complete understanding of `my in-Y vention, reference will be had to 'theffol- Y and accompanying 'drawi ir1`g`s',lin,which:'y i
