Specification of Letters Patent.
Patented June 12, il itli Application filed January 10, 1917. Serial No. 141,588.
This invention relates to that class of inelined screening or separating machines in which the screen are percussively jarred or vibrated, and the invention relatesmore particularly to certain improvements in the machine of the Bell and Sturtevant Patent No. 923,108, dated Way 25, 190$), in which the screens are jarred from hammers or strikers arranged below the screens. The present improvement hasspecial reference to the hammer or \gibrating" mechanism for percussively jarring the fine screens of the sc| )a rators.
In accordance with the present invention the fine screen is percussively jarred from below by means of hinged hammers striking: at intervals on the bottoms of spring: sustained impact bars which yieldingly support the screen or screens to be jarred.
The accompanying drawing a detail view illustrating one of the improved jarring" devices, a plurality. of which will of course be used in each separating machine for jarring the screen or screens.
Referring to the drawing, 12 denotes the bottom of the screen box or casing to which is attached a hanger 13 a plurality of which will be provided For supporting a rotating shaft ll provided with disks 15 to which are hinged hammers l6. Attached to th casing parts 12 is a support 17 through which extends an impact bar or pin 18 encircled by a supporting spring 19 which thus yieldingly sustains said impact bar in said support. The impact bar is provided at its top with a head 18 between WlllCli and the bottom oi said support said spring 19 is interposed, and on which head rests a transverse protection plate 20 attached to a wire mesh screen 21, so that the said screen will be yieldingly supported by the impact bars 18, a plurality of which will, in practice, he provided.
From the foregoing it will be understoodthat when the machine is in operation the screen 21, which is yieldingly supported by the impact bars 18, will be percussively jarred by means of repeated blows of the hinged revolving hammers 16 acting up wardly on the said impact bars.
Having thus described my invention I claim and desire to secure by Letters Patentz V 1. In a separator, the combination with a screen, of impact bars by which said screen is supported and rotating hammers acting intermittently from below on said impactbars.
2. In a separator, the combination with a screen, of yieldinglyanounted impact bars by which said screen is elastically supported and rotating hammers acting intermittingly from below on said impact bars.
3. In a separator, the combination with a screen casingpart provided with supports, of impact bars passing through said supports and provided with heads, springs interposed between said heads and the bottoms of said supports, a screen elastically supported by the said spring-mounted impact bars, an'd hammers acting at intervals on said impact bars.
a. In a separator, the combination with a screen casing part provided with supports,
of impact bars passingthrough said sup-' ports and provided with heads, springs 1ntel-posed between said heads and the bottoms of said supports,a screen elastically sup ported by the said spring-mounted impact bars, hammers acting at intervals on said impact bars, and revolving disks to which said hammers are hinged or pivoted.
In testimony whereof I aiiix, my signature THOMAS JOSEPH STURTEVANT.
