VIBRATILE SCREEN.
lAppllication filed August 31, 1922. Serial No. 585,349.
To all whom t may concern.;
Be it known that we, COLIN R. WALco'r'r and WALTER J. PIKE, citizens of the United States, residing at Newaygo, in the county of A l Newaygo and State of Michigan, have invented new and useful Improvements in Vibratile Screens, of which the following isa specification.
The present invention relates to vibratile screens; and its object is, generally, to
'provide improved means for supporting such screens; and, more particularly, to provide l means for yieldingly supporting the middle portion of the `screen independently of, l5 and movably relatively to, the means which supports its edges; and further, to provide improved means for stretchingly mounting such screens; and further,lto provide improved means for preventing leakage at the edges of such screens; and'turther, to provide improved means for preventing the breaking oi such screens adjacent the mounting thereof.
These and any other objects hereinafter appearing are attained by, andthe invention finds preferable embodiment in, the structure hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which Figure 1 is a iront view of a vibratile screen structure;
Figure 2 is a sectional view thereof taken on a vertical plane corresponding to line 2-2 or Figure 1;
Figure 3 is a like view l(enlarged) of certain parts;
Figure t is a transverse sectional view of a portion thereof taken on line l-Zi of' Figure 3; y l
Figure 5 is a side view of a portion thereof;
Figure 6 is a plan view of a rotatable shaft and cam wheel carried thereby;
Figure 7 is a transverse sectional view (en- 4&5 larged, of certain parts taken on line 7-7 of Figure 1;
- Figure 8 is a side view of the same;
Figure 9 is a transverse sectional view (enlarged) oi a portion ci said structure taken on line 9 9 of Figure 1; and
Figure 10 is a transversesectional View of certain parte taken on line 10-10 of Figures 1 and 3.
ln the embodiment of the invention chosen 555 1to1' illustration by the drawings and for is threaded a screw 5 for effecting such angular adjustment. The material to be screened maybe delivered to the upper side of the screen 6 through the inlet 7, the portion of such material which passes through the screen falling on the inclined bottom. 8 of the frame and thence passing through thevent 9. The screen is supported adjacent its opposite side edges on the frame in the following mannerLAs particularly shown'in Figures 1, 7 and 8, one (or preferably both as shown) of these side edges are secured to strips 10 bent over to form hooks l1 (see Figure 7), said strips resting on the inwardly-eXtending shelf portion 12 of the frame. A member 13 abuts at its upper or outer edge portion 14 o-n the inner surface of the body portion 15 of the frame, (its said portions 12 and 15 being thus angularly disposed relatively to each other), and the lower or inner edge portion 16 of the member 13 engages in the hook of strip 10, all as seen in Figure 7. Screws 17 threaded in the frame and passing through the member' 13 serve to stretch the screen to a desired tautnepss, the lower edge portion 16 of the member 13 sliding along the shelf portion 12 of the ira-me toward the frames other portion 15, and the upper edge portion 14 of said member sliding along the inner vsurface of the portion 15 of the frame and away iironiits shelf portion 12, as the screw 17 isscrewed down. The screen is yieldingly held. in the degree of tautness to which it has been thus adjusted by the spring 18 surrounding the shank oit' the screw and pressing between its A Tc prevent leaktion 12.v These packing strips being resilient, and the lower fold of the screens edge strip 1() being bent downwardly at 21, the screen adjacent its supported edges is prevented from a sharply bending movement graduall along itslines of support so that the* repeat- "ed vibrations ofthe screen may not result Vin .a breaking thereof adjacent such edges.
ing in bearings 261CA on the cover 25 hinged .at 26, said shaft being rotated as vbyf'the pulley 27. The movement of this cam wheel depresses-r the anvil -28 mounted .on the ree end 'of the -springable bar 29,
-l v,such edge portions; andthat as the highv which action depresses the screen by pressing the bar 29 against the outer end of the upwardly or outwardly extending post 30 This postis thus secured as by screws passing through the thin bars 31, 32'on the op'- site sides ofthe screen,'the upper bar 31 Eingattached at its ends to the frame as byjlugs or bolts 33 passing through elongat ed slots 34;.in said bar, whereby a sidewise .adjustment of the screen on the frame 'is permitted. The middle rtion of the screen issupported by the iollowing mechanism:l
A'plunger 35, slidable in a bearing 36 on theframe, has a head v37 adapted to con' tact the lower side of the screen, being pressed 4into such contact by a spring 38, as
particularly shown in Figures 2 and 3. The tension fof this spring is regulated by a second plunger 39- slidable in the plunger 35 as shown in Figure 3 @and adjustable by a nut 40 on the screw 41 carried at the free lend of Vthe lever 42 ulcrumed at43 on the frame and supporting thei lower end of the second plunger 39,'as will be readily understood. It will be seen'that the middle portion of' the screen is thus supported independently of its edge portions and by means` movable .relatively to the means supporting parts of the cam wheel pass oil' of the anvil l 428, they middle portion of the screen is suddenIy thrown upwardly by the spring 38. A. ievxible cover. 45 of suitable material (as leather) and attached to the. under side of the bar-29 and to the upper side of the cover 25l prevents leakagethrough the open ing 46 in' the cover. t
The invention being intended to be pointed out in the claims, is not to be limited to `or by details of construction. of the particular embodiment thereof .illustrated by thel drawings or heneinbefore shown or described.
-What is claimed is 1. In mechanism of the character described; sfscreen; a frame having angularly-disposed portions; means for mountsecured to the middle portion of thefscreen.
portion holdingly engaging the screen there-V between and the other portion of the frame,
and adjustable means for moving and holding said member on the frame; packing intermediate said ,member and the first-mentioned portion of the frame, and intermediate the screen and the last-mentioned portion of the frame.
2. In mechanism of the character described; a screen; a frame `having angularly-disposed-portions; means for mounting'the screen on the frame comprising, a. member having. an edge portion abutting one portion of the frame and another edge ,portion holdingly engaging the screen therebetween and the other portion of the frame,
and adjustable means for moving and hold- 1. ing said member on the frame; a resilient strip 4intermediate the screen and thel lastymentioned portion of the frame.
In testimony whereof we have hereunto set our hands at Newaygo, Michigan., this 23rd day of August, 1922.
