To (ZZZ whom it may concern: Be it known that I, Monnnr PUNsnoN REYNOLDS, n citizen of the United States,

end a resident of Cleveland, county of Cuyahogs, end State of Ohio,-have invented a new and useful Improvement in Screening Apparatus, of which the following is a. specificntion, the principle of the invention being herein explained and the best mode in which I have contemplated applying thntprin'ciple, so as to distinguish it from other inven;

' hes been found. that light Woven wire screens 263 'movement nnoler vihretion to efifect' s rapid,

of fine Wire rennet he given it sufficient end, eecnretc screening notion, except with to the screen, time to. the very considershle stretching sensed on. the wires of the screen by the continued vihretion, end by the weight or theloed pressing thereover.

While c ordinnry enriount of stretching is ice to the screening notion, nevertirn s i Ne tie l'rsit stretching beyondt he wires, censing ringthtrn iinble h g the it n of the I The pr developed to closed moons constituting, however, but one.

screen, when snb iected to sel" conti nonsly ten ihrntory c is some o'nt beyond. the

scr'ens in order to tching or the hretorv irnp' wh chv screens must subjected to seenre the propervr when working under s henvy lend msteriei, To tire accomplishment of the iioregoing endrelnted ends, one, invention,

then, consists oi the moons hereinafter fully-described end pnrticnierly pointed out in'the'cieims, Y

'lhe e'nnened droning end the .foliowing description set'torth injdeteil certain mechnnism embodying the invention, such distheir ends h the very ofwnrious mechanical forms in which the principle of the invention may he used;

In said ennexed drawings:-

F 1g. 1 IS a plan view of my improved screen niounted upon s frame and partially in sectlon to show the construction; 2 is etransverse section across the some; and

Figs. 3 and 4 are enlarged partial transverse sections illustreting the vnrious means for mounting the screens. I

. In screening operations a very high. tonnage of material is sometimes passed over the screen, and the weight of themeterinl causes it universal stretching of the wires or the screen, which is of course eccentueted in some pieces due to uneven temper'of the wire from whichthe screen is woven, This is perticnlerly true in the case of light screens which do not have the strength end resistance of those of coerser-inesh,

My invention consists in providing e series of resilient supporting niernhers'for rein forcing; the screen, these inemhe rnost convenientiy provided in tit second ccsrser screen mounted l3 fine screen. in Fig. i there is shown :r i Mme consist of rnovnhle form of pistes 1 freely s upon transverse n J m- 1 ti e: a, 11% it who: scjflrsla M .w i with suites-1e e pert ,ee i. on the snri'nces o A 1 .c are see 1 strips or interned nlso re hent for clamping between the re-hent trictionel material 12 and the lower or coarser screen is supported from the re-bent flange 8 by a second similar strip 13, thus enabling the flange on the strip 6 to be clamped down tightly against the inturned edges of the screen without injuring the same, although, at the same time, securing a firm grip on these edges.

If desired, two S-shaped hooks 14a and 15 may be used as shown in Fig. 4:, in which case the lower strip 15 is wider than the upper and carries the coarser screen 11, which is, however, in substantial contact with the upper screen 10, as is also the casein the mountmg shown in Fig. 3. The two screens may be tcnsioned simultaneously and uniformly by the adjusting bars which act to space the angle plates 1 and thus pull the $-shaped strips away from each other throughout their entire length.

The action of the lower or supporting screen is to reinforce the upper screen against the weight of material passing over it, and at the same time to assist in the vibration of the same, since a better vibration can usually be secured from. a coarser wire than from the very fine wires which are used in fine mesh. screens. The screening action is not effected by the'supporting screen as the meshes of this screen are of course in every case larger than the meshes of the upper screen, and any material ing through the uper screen will similarly pass through meshes of the lower screeni @ther modes of applying the principle of my invention may be employed instead of the reasons one explained, change being made as regards the mechanism, herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In. mechanism of the character described, the combination of spaced pairs of superimposed strips rebent laterally upon themselves throughout their length, Woven wire screens mountedupon the corresponding strips of the pairs and having their overlying edge portions clamped beneath such reb ent portions of said strips and meansengaging said strips for moving the same with respect to each other to tension said two screens equally and together.

2. In mechanism of the character described, the comhination of spaced strips rebent laterally upon themselves throughout their length, said rebent portions being in ofi'sct relation, two superimposed woven Wire screens having their overlying edge portions clamped beneath such rebent portions of said strips, frictional material interposed between such clamped edge portions of said screens and said scrwns being of different mesh, the coarser mesh being below the other and means engaging said strips for moving the same with respect to each other to tension both screens simultaneously to fixed uniform predetermined tensions.

Signed by me, this 16th day of Eept, 1-919.
