SCREENING AND SEPARATING MACHINERY.
. Application filed August 8,.
To all whom 1'15 may concern.
lie it known that I, HARRY S. VRooMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Screening and Separating Machinery, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to screening and the provision of a new and improved machine of this general character.
In one form of its employment, my improved machine is of great use in connection with the screening and separating of sand or other such similar material, although of course, my invention is not so limited. I show however, herein and describe one specific form of carrying out my invention and in this particular form the machine which is constructed in accordance with my invention is particularly adapted for thus screening and separating sand or similar material, and I will describe my invention in connection with such a particular machine having it understood of course, that in thus describing it, I am not limiting it as this application sets forth merely one of the forms which my invention may take. I will also use the word sand herein to signify main may be satisfactorily employed.
In the general form of the machine shown chute and a plurality of screens which may by means of which the sand is screened and separated.
My improved machine contemplates .the mounting of the screening devices in such a way that they are agitated in a novel manner to secure the most efficient screening effect and at the same time insure the progressive movement or discharge of sand thatremains as residue. The machine may be operated through any suitable power agency or manually if desired, a suitable power motor being herein shown by way of illustration. The machine is arranged 'in such a way that it is portable. The claims herein are limited to the machine without the" rolls or crushing devices as claims covering the col'nbii-iation of the screens and crushing Specification of Letters Patent.

devices have been made the subjectv matter of a co-pending' application Serial No. 650,214, filed Sept. 19, 1911.
My invention also contemplates a great many novel constructional features and arrangements, such for instance as the removable mounting of screening devices within suitable screen frames, all as will appear more clearly from the detailed description of one embodiment of my invention-which will now follow in connection with the accompanying drawings illustrating this embodiment, in which:
Figure 1 is a longitudinal sectional view of my machine; Fig. 2 is a sectional view on lines a-avof Fig. 1; Fig". 3 is a partial end view looking toward the right of F ig. 2; Fig. at is a partial end view looking toward the left of Fig. 2 with the motor removed; Fig. 5 is a perspective view of one of the screens and screen carriers; Fig. 6 is a de tail view of a portion of a screen; Fig. 7 is a detail view of a portion of the driving mechanism and the rolls of the machine, and Fig. 8 is a detail of construction. Referring to the illustrations, I show a framework consisting of the two vertically arranged side members 1 and 2 which are held together by cross strips 3, 4, 5 and 6. A transverse plate 7 is provided to hold a motor 8, if such is employed, which motor by handles 11 so that the machine is portable and may be rolled from place to place.
Amovablymo-un-ted screen frame 12 is provided in theupper portion of the machine and betweenthe side frames 1 and 2 and is provided with bearingplates 13 -to which are rotatably mounted links 14' on pins 1-1, each link being rotatably mounted on a stud 15 secured in the-side frames. The right hand extremity of the screen frame also carries bearing plates 16, which by means of studs 17 are rotatably supported upon the upper extremities of rocker arms 18. These rocker arms are supported upon studs 19 in the'side frames of the machine. The lower extremities of the rocker arms 18 carry by means of rotatably mounted studs 20 suitable bearing plates 21. whichbearing plates are fastened to a second screen frame 22, at or near the right hand extremity thereof. The left hand extremity of this second screen frame carries two supporting plate 23 side members 1 and 2 by means of the studs It will thus be seen'that if the rocker arms 18 are moved to and fro that the screen frames 12 and 22 are oppositely agitated,
namely that they are moved from r1ghtto teft and vice versa, and that their extremiare also-given a slight up and down motion in Connection with this horizontal motie-n. This peculiarity of the motion thus imparts to each extremity of each screen frame a rotary motionrespectively about the studs 15 and 19 in the case of the screen frame .12 and about the studs 25 and 19 in the case of the screen frame 22. The arrangement is also such that while one extremity of the screen frame is receiving its upward motion, the other extremity isreceiving its downward motion. A very ei'licient motion is thus secured for properly agitating the material to be screened. The
' The shafts 34 and 35 are mounted in suitablebearings 36' and 37 respectively whose position is governed and adjusted by springs 38, 38. The shafts 34 and 35 carry rolls 39 and 40 respectively and these rolls are mounted as shown for a purpose which will presently appear although these rolls form no part of my present invention. An adjustable chute 41 is pivotally mounted at 42 and can occupy the position shown in full lines in Fig. 1 and alsothe alternative position shown in dotted lines in the same figure. This chute when occupying the position shown in full lines in Fig. 1 directs the refuse or residue which is cast away from the screen. frame 12 between the crusher rolls 39 and 40 when such rolls are used where this residue may be crushed and then deposited into the screen frame 22. rolls are used the rejected material is of course in that casedeposited directly upon the screen frame 22. The screen frame 12 hasia screen '43 and the screen frame 22 has a screen 44. The material which passes with suitable When no through the screen 43 falls onto the screen 44 and is further directed toward the upper lefthand portion of said screen 44 by means of abaiiie plate 45 mounted on the frameworkas shown. The screen frames 12 and 22 consist of two side members and an end member, the lowermost extremity of said screen frames being open-as shown so that the material left on the screen after screening may pass off from the screens 43 and 44 respectively. The side and end members of these screen frames are each provided with flanges to support the screens 43 and 44 and to provide the necessary strengthening of the screens, cross members 46 are employed as shown on which the screens rest.
The screens themselves consist of a net work 47 suitably bound at their ends and sides by the angle plates 48 and rivets 49. The screens themselves are thus bodily removable from the frame for purposes of interchanging or repair as the case may be. The method of removal is illustrated in Fig. 5 by the dotted lines.
The general operation of the machine will thus be apparent. The material to be separated and screened is placed within the screen frame 12v upon the screen 43. The motor 8 is startedin operation, thereby oscillating the rocker-arms 18 and causing a suitable oscillatory motion of the frames 12 and. 22 carrying the screens 43 and Some of the material falls through the screen 43 and is directed by means of the battle plate onto the second screen 44, which second screen 44 may be of finer mesh than the.screen 43. The material is again sifted by the screen 44 and the fine siftings are deposited within the receptacle 51. The residue from the screen 44 is thrown out from'the screen frame 22 into a receptacle 'The material within the receptacle is of course fine enough to have passed through the screen 43 and-there are thus two sizes of screenings, those within the receptacle and those within the receptacle 52. A third grade of screenings oflarger size have been thrown off from the screen 43 and these may be suitably collected outside of the machine if the chute 41 be in the position shown in dotted lines. If the chute is in the position shown infull lines in Fig. 1, then this coarse material which leaves the screen 43 is directed by means of the chute 41 between the rolls 39 and 40 and is crushed by these rolls and deposited upon the screen 44, or is depositeddirectly upon said screen ,if no rolls are used, in a more finely divided condition so that it may be again-sifted. It will thus be seen that my improved machine separates-the original material and provides means to segregate the coarse particles so that they may be available for further;
