W/TIVE88E8: A mm/mk 2% A 4 7 BY ATTORNEY COLUMBIA PLANOGRAPH CO.,WA5HINGTON..D- c
FREDERIG S. CONVERSE, OF BINGHAMTON, NEW YORK.
ROTARY SCREEN.
Specification of Letters Patent.
Patented Apr. 1,1913.
Application filed April 17, 1912. Serial No. 691,535.
To all whom it may c0ncem:
Be it known that I,-FRnDER1o S. OoN- VERSE, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in R0- tary Screens, of which the following is a specification.
My invention relates to improvements in rotary screens for screening and sifting sand, coal and other screenable substances.
.The purpose of my device is to obviate and prevent the sand and other fine sub stances being screened, from clinging to the interior sides of the screen.
Vith this object in view my invention consists in certain novel features of con struction and arrangement of parts as will be hereinafter more particularly set forth I in the claims, reference being had to the ac companying drawings in which Figure 1 is an end elevation of my device, Fig. 2 is a perspective view of a part of my device, Fig. 3 is a plan view of a part of my device, Fig. 4 is a front elevation in perspective of a part of my device and Fig. 5 is a front elevation of a part of my device.
The same reference characters denote like parts in each of the several figures of the drawings.
In carrying out my invention, I provide an ordinary frame B on which is mounted the usual rotary screen, represented by G. On the screen body O I have the sectional screen coverings D. On the outside of the sections of the screen covering I mount the bands E, having loops 4, 4, 4, 4, etc. The ends of said bands E terminate in the loops 5, 5. These loops are formed by the bands E having their ends turned back and fastened to the sectional covering by means of the nut bolts 6, 6, which hold the band ends firmly to the sections.
The covering for my rotary screen is made up of two sections. On the frame B I mount a frame A, as shown in Fig. 1, formed of the uprights w, :0, and the cross piece 3 Mounted on the support 00 of frame A I have the knocker F turning on the pivot 7. This knocker is provided with the two arms 8. Between the arms 8 I have the roller 9, composed of metal or other heavy substance. The frame A and the knocker F are so located that the roller 9 tracks with the bands E and the loops 4, 4, 4, 4. IVith the turning of the screen O the knocker F is raised up and down by the passing of the looped band, and as it falls to the band surface in the space between the loops, the blow thus struck causes a vibratory motion of the screen cover which causes the sand and other substance gathered thereon to fall to the bottom of the interior of the screen and prevents a steady accumulation of substances on the meshes of the screen. The rapidity of this knock or movement of the knocker F depends of course upon the rapidity of the movement of the screen and the fall of the knocker. I
Having thus described my invention, what I claim as new and for which I desire Letters Patent is as follows:
1. In a rotary screen in combination a rotatable screen frame, a cylindrical screen mounted on said frame, a band surrounding said screen, said band being provided with loops forming raised projections ofappreciable height, and a pivoted knocker arranged tangentially to said screen at its top and provided with a knocking roller of a diameter approximately equal to the height of said loops, whereby upon rotation of the screen, the knocking roller acts both tangentially and radially to vibrate the screen, substantially as described.
. 2. In a rotary screen in combination a rotatable screen frame a cylindrical screen made up of two or more sections mounted on said frame, band sections surrounding said screen sections and coextensive in circumferential length therewith, said band being provided with loops, forming raised projections of appreciable height, and a pivoted knocker arranged tangentially to said screen at its top and provided with a knocking roller of a diameter approximatelyequal to the height of said loops whereby the knocking roller acts both tangentially and radially to vibrate the screen, substantially as described.
In testimony whereof I have affixed my signature in presence of two witnesses.

S. A. VALENTINE, F. E. CAMPBELL.
