SCREEN FOR DRY FANS:
Specification of Letters Patent.
Patented Dec. 31,1912.
Application filed October 16,-1911. Serial No. 654;800.
To all whom it may concern:
Be it known that I, JOHN F. MonoAn, citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Screens for Dry Pans; and
' I do declare the following to be a full, clear,
. screens for the dry pans of mills such as are used for-disintegrating shale preparatory for use in the ceramic arts, and for disintegrating other materials for use in other arts.
The object of the invention is to provide the dry pan witha maximum amount of screening surface. i
A. further object is to provide screens of a durable and efficient character, and which are easily renewable without removing an entire screen, as will be hereinafter fully set forth. v
In the accompanying drawings: Figure 1 is a top plan view of one of the screen segments. Fig. 2, a section on the line 6-1) of Fig. 1. Fig. 3, a section on the line c-c of Fig. 1. Fig. 4 is a perspective view of a portion of one of the screen bars and Fig. 5 is a perspective view of the bar'for spacing the screen bars. i
In the specification and drawings, similar -referenc characters indicate corresponding parts.
8 designates a disk upon which shale is pulverized in a well known manner. Spider arms 11 and rim 12 of the dry pan are also well known parts of a shale pulverizing mill. After the-clay is pulverized by the action of the mullers and the disk, it is thrown onto a series of screens which are mountedon thedry pan around the disk 8- andrevolve therewith. These screens are made up of a series of transverse bars 13, which are preferably made of hard rolled metal; The ends of said bars-rest upon flanges 14 of the spider arms 11. {lhe upper edges 15 of the bars 13 are uniformly spaced apart to form segmental screens. The bars of each segmentare held in such position by means of 5 acing bar 16, having teeth 17 between w ich the ends of said bars 13 rest. The spacing: bars 16 are mounted in pockets 18 in the spider arms 11, as shown in detail in Fig. 2.
In assembling each segment of the'screen to the spacing bars are first placed in position wand the bars 13 forming the screens are dropped into the spaces l-ehvt-cn the teeth 17. The said bars 13 are held in such position by plates 19 which rest in recess-vs 2O in the ends of the bars 123. The plates are attached to the spider arms 11 by screws 21, the nuts 2-2 of which rest in recesses 23 of the spider arms 11. This manner of attaching the screen bars is preferable and is carried out in practice when the machine is constructed in its ,entirety, 'with the screen bars attached directly to the spider arms. The spacing :bars 17 are instrumental in keeping the screening bars 13 evenly spaced so that the resulting product will have the..- desired uniformity of texture. able that said spacing bars be made separable from the arms 11 to facilitate the making thereof and to insure accuracy of the recesses thereof which receive the screen bars.
Without limiting myself to the precise construction and arrangement shown and described, which may be varied within the scope of the claim, I claim:
In a device of the type specified, a frame provided-with a plurality of arms having pockets therein, a plurality of parallel screen bars mounted on said arms, said bars being provided with recesses on their ends and upper corners, spac ng bars mounted in said pockets and receiving said screen bars-and thereby holding said screen bars properly spaced, and plates mounted on said arms and received by said recesses and holding said screen bars in position when properly spaced. I
In testimon whereof I afiix my signature, in presence 0 two witnesses.
JOHN F. MORGAL.
