Specification of Letters Patent. Patent-tad Aug. 22}, 1922.

Application filed August 22, 1919. Serial No. 319,084.

T 0 all whom it may concern.

Be it known that we, EDWARD J. Moore and RAYMOND H. Moonn, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Separators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to separating apparatus, and more particularly to apparatus designed to separate various grades of sand or cleaning material from the dust mingled therewith. The general object of the invention is to improve and increase the efficiency of such apparatus. Further and more limited objects of the invention will appear hereinafter and will be realized in and through the combinations of elements embodied in the claims hereto annexed and illustrated in the drawings forming a part hereof, wherein Fig. 1 represents a sectional view of such apparatus, corresponding substantially with the line 11 of Fig. 2, certain parts being broken-away; Fig. 2 a sectional vie-w corresponding to the line 22 of Fig. 1; Fig. 3 a detail in perspective of the valve mechanism connected with one of the delivery outlets from the apparatus; and Fig. 41 a sectional view corresponding to the line 4-1 of Fig. 1 and looking in the direction of the arrows.

Describing the various parts of the drawing by reference characters, 1 denotes a pipe, the inlet end whereof may communicate with the bottom of a screened hopper and with the dust space therein, such as shown in our copending application No. 319,083, filed August 22, 1919. The upper or de livery end of this pipe extends through the inclined bottom 2 of a separating casing, 1ndicated generally at 3, said casing having an outlet connection 4: at the top thereof leading to the dust collector (not shown). The inclined bottom 2 may be formed on a bottom section suitably secured within the bottom of the casing 3 and having a vertical wall 5 with-which the lower end of the inclined wall 2 is connected. Immediately above the lower end of the inclined wall 2,

the wall 5' is provided with a wide slot orfrom one wall thereof and a bafiie 9, projecting from the. opposite wall between and overlapped by the ends of the former bafiies. The upper end of the pipe 1 is shown as extending somewhat above the top of the bottom section and communicating with a chamber within the casing formed by a vertical wall 10 connecting the side walls 11 of said casing and an upwardly inclined wall 12 also connecting the said side walls and extending from the top. ofthe wall 10. The upper end of the wall 12 is preferably curved to provide a bearing against the wall 13 01 the casing. This wall is provided, below the top of the wall 12, with an opening which may be closed by a sliding door 1 1. 15 denotes a wallor partition secured at its lower end to the wall 16 of the casing and extending upwardly therefrom, being secured to the walls 11, as by angle clips 17. This wall forms with the wall 12 and the walls 11 of the casing a duct which is gradually enlarged. from the bottom to the to thereof. Extending above the upper on s of the walls '12 and 15 and projecting inwardly from the wall 13 is a horizontal baiile 18. This baflie may be secured to the walls 11 as by means of angle clips 19.

, Immediately above the junction of the bottom of the wall 15 with the wall 16 the latter is provided with a slot or opening 20 communicating with a hopper 21 having a discharge chute 22. Extending around three sides of this chute is a guard 24, which may be supported from the said chute. Secured to said chute. are arms 25 in the projecting ends. of which there is mounted a rod 26. Mounted on the ends of this rod. is a U- shaped bracket 27 supporting a swinging valve 28. The valve is connected intermediate of its ends to the bracket, the outer end being provided with a counterweight 29 which tends to hold the valve against the bottom of the chute.

The apparatus hereinbefore described is designed for the purpose of recovering from the screened hoppers of said blast apparatus various grades of sand delivered through the screens and separating the dust there from. In operation, air laden with sand and dust will be forced intothe casing 3 through the pipe 1 and into the open-bottomed chamber provided beneath; the wall 12; The shape of this wall and the arrangement, of

the chamber. outlet between the bottom of 1 10 I as separating chamber, the air laden with finer and lighter sand and dust passes upwardly between the plates 12 and '15 toward t'he' -wall 13 and is directed and whirled laterally-toward the wall 16 "by the baffle 18. The lighter sand, which is-suitable for the making ofycorespwill be separated from the air 'by this last'whirling movement'and discharged into the-hopper 2l'by the walls 15 and 16 through the slot 20 Then a sufficient "quantity of this-sand'lhas accumulated -upon the valve 28, the latter is, automaticalflybpened'and the sand discharged from the bottom of the'hopper, the guard 24 serving to prevent lateral dispersion of this sandand toguide-it to a suitable receptacle. From thenpper part of the-casingB the air, now :laden with dust, may be conducted to a suitable dust arrester or collector '(not shown). Y 1
