mills, though it may be useful in other con-" nections for its sifting function.
The principal obyect of the invention 1s to provide an air circulation means which may be easily attached toan-y sifter or "bolterused in flour mills with very little alterations andexpense.
Another object of the invention is to provide a simple and efficient air controlling means which will also aid in controlling the flow of stock. V
A further object of the invention is to' generallyimprove upon devices of this'nature by providing one which will be extremely simple, durable and inexpensive in construction, one which is efficient and reliable in operation, andwell adapted to the purpose for which it is'designed.
c c With these and other objects in view, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter p fully described. c
In the'drawing:- V Figure 1 is a fragmentary side elevation of the device, and
Figure 2 is an end elevation thereof showing portions in section;
7 he numeral 1 represents a sifter or bolter of conventional construction which isv provided with openings in the topthereof for "receiving the stock spout 2 and the cylinders 3 and 4' which are situated at the-head and tail of each section of the sifter or bolter respectively. These cylinders 3 and 4 are constructed of cloth or fabric material and are provided at their top portions with the collars 5 having the flanges 6 which are attached to the boards 7 in anysuitable man- V ,[Specification of Letters Patent. Patented Apr, 4, 1922, Applicationfiled August 3, 1920. Serial No. 400,908.
ner. These boards 7 may beextended and fastened to any suitable support. It will of coursebe understood thatthe. function of the board 7 is to hold the cylinders 3 and 4 inan extended position. Apertures are provided in the boards 7 so as to receive the rods 8 which have mounted upon their inner ends the valve disks 9 so that the circulation of "the air may be controlled. "-It will of course be readily understood that the farther the'disk is moved upwardly the r greater will be the circulation and "vice versa. V c lVith' this device asdescribed 'it will be readily. seen that the flow of stockcanbe regulated causing it to boltmore thoroughly" instead of tailing over as would be -the tendency without this air circulation.
- From the foregoing description, taken in connection with the accompanying drawing; the construction and operatlon of the device can be readily understood without a more extended explanation. its numerous changes in. form, proportion and in the minor details of construction maybe re sorted to without n departing from the spirit ofthi invention, 1 do not wish to be limited to the construction herein shown and described other than as claimed. ,g
Having thus described 'iny invention what I claim as new 1SI;
1 In combination'with a sifter, a pair of cylinders constructed of fabric 'm'aterial, a means for holding said cylinders in an extended position, and valve means situated within said cylinders.
I 2(In" a sifter, a support, a cylinder formed offa'bric material depending from 'I tl18 support, means for holding vsaid cylin- I c der inlan extended position, a stem extending throughlthe' support and the cylinder and a disc valve mounted on the inner end ofQthestem so as to be movable longitudi- 'nally inthe cylinder. g
' In testimony whereof I aliix my signa" ture inpresence oftwo witnesses.
