VACUUM SEPARATING APPARATUS.
Specification of Letters Patent.
Patented Nov. 18, 1919.
Application led .Tune 20, 1919. Serial No. 305,533.
To all whom z't may concern.'
Be it known that I, ISRAEL S. SHERMAN, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Vacuum Separating Apparatus, ofl which the following is a specification.
My improvements relate to vacuum apparatus for the pneumatic separation and collection of dust and light particles of matter from heavier material or surfaces; and the invention consists in the construction and arrangement of parts her-ein described and claimed specifically, whereby the device may be utilized for the sifting of'ashes, etc., as well as for sweeping, dusting and similar purposes, 1 distinctive feature being its `adaptability for use in conjunction with an ash can, barrel or receiver of any kind into which the ash or dust is deposited, in contra distinction to the old method of collecting such pulverous material in the filter bag or screening member.
In the accompanying drawings,
Figure l, isa top view of my screening apparatus, broken away in part;
Fig. 2, is a side elevation of the screen asapplied to a refuse receptacle, parts being broken away;
Fig. 3, is a front elevation of the sifting nozzle and Fig. 4, a sectional detail thereof;
Fig. 5, is a sectional elevation taken upon plane of line 5-5, Fig. l;
Fig. 6, is a horizontal section taken upon plane of line 6 6, Fig. 5;
Fig. 7, is a sectional detail taken upon pl-ane of line 7 7, Fig. 6, showing one of the clamps of the expansible ring of the Screener; f
Fig. 8, is a similar view, showing a modiication.
-What may 'be designated as the screening member S, considered as a whole, consists essentially of a skeleton frame-work vcomprising a cap plate p, a plurality of equidistant Suspenders s, s, attached to said cap plate p, and an expanslble ring e, secured to the lower portions of said Suspenders sbs. These parts form the support for the exhaust or suction device D, the screening cloth c, and the apron a. 4The exhaust or suction device D, is preferably of the fan type driven byan electric motor in a manner Well known in the art, the vacuum chamber al, communicating with the flexible suc cured to a flange 222, on the under side of the 5 cap plate p, while their lower ends are in like manner riveted or otherwise secured to the sectors, e, e, which form the expansi'ble ring,-two of said Suspenders being secured to each sector e, as will be understood by reference more particularly to Fig. 6, by which it will be seen that the sectors e, e, overlap at adjacent ends, a pin e', on one part engaging the sides of a slot e2, in the other asindicated in Fig. 5. The screen cloth c, is atv tached to the cap flange p2, by a binder b, of an Asuitable character, and is of suiiicient length to extend down to the expansible rin e, to which it may be attached in any desired manner. The upper edge of the-apron a, is stitched or otherwise secured to the screening cloth c, and its lower edge is formed with a felt or similar packing a', of suffi-- cient weight to insure close contact with the exterior of the receptacle.
Said receptacle R, may be of any desired or suitable cl'iaracter, as an ash can, barrel or similar container for the pulverous matter collected. It. is preferably although not necessarily circular in cross section, and for convenience of illustration I have shown it as of cylii'xdricai form. It is portable in character, so that when the screening member S, is removed therefrom it can be inde' pendently handled for the disposal of its contents.
d The screening member S, is supported upon and over the mouth of the receptacle R, by means of bracket arms e3, attached to the expansi'ble ring @,-said bracket arms e3, resting directly upon the edge 71, of the receptacle R, and being formed with pendent members e, provided with binding screws e5, by which the screening member S, may be temporarily but positively secured to the receptacle R, as will be understood by reference more particularly to Fig. 7. That is to say, the sections of the expansible ring e are, by means of the screws e5, clamped against the inner surface of the mouth of the receptacle', the overlapping of the sections e, e, of the ring, allowing it to conform to the size and configuration ofsaid mouth or o ning. In order to attain a relatively tight .joint between the mouth of the recep- I 4tacle and the expansible bearing ring,the
latter is provided .with a padding ei, of felt or other suitable materiah'so as to insure a close fit. -This padding e", is omitted from Fig. 6, in order to-inore -clearlyshow the construction and arrangement ofthe other I' parts; and is also omitted in part from Figs. l
I in excess of atmos heric pressure.
2 and 5, for a like reason, but its function is clearly indicated in Figs. 5 and 7. How'- ever,'in orde-r to intercept any i-mpalpable powder that might be forced through the -joint by the' pressure Within the Screener S,
the latter is provided with the external apron a, which extends below the edge 1 of the rece tacle R, and mitigates the effects of. such lea age, if any. l
The Woven textile fabric constitu-ting the screen c, is of a character especially prepared for the. purpose and adapted to intercept. the passage of solid rticles, no matter how small, while allowing the escape of air The flexible suction tube t, terminates in a nozzleN, of peculiar construction in that it is formed with a `relatively largev inlet n, provided` with a reticulated screen n', adapted., to exclude'coarse material while -admitting the entrance .of pulverous material'which is drawn in with the air as a vehicle owin to the partial vacuum created in'the chamer d, b ythe exhaust mechanism. By the provision and use of a nozzle N, of this character, my a paratus is adapted for use as a means o separating ash from cinders, etc., Aas well as for the various other Apurposes to' which vacuum cleaners have heretofore been applied.
The expansible e, is' an important factor in adapting y e screening member S, to' fit and compensate for variations in size of the receptacles to which it may be applied. Ordinarily and preferably the e, is made tot the interior surface of i the mouth of the. reeeptacle'R, as shown in thedrawings,'b ut incertain cases it may be desirable -to fity it around the mouth exterv nally, in 'which case a form. oi clamp shown g, may be substituted for that vshown @It is to be noted'that the pulverous material is recipitated from the suction chamvber d, t rough the discharge port p', verticallymnd axially vas related to the-.screening member S, and the receptacle R, below 1t, thus aiding gravity in the separation .of the solid matter from the air vehicle by which. it has been carried over into the itself readily esca screening member, while 'the air vehicle laterally through the screen cloth c, We above the receptacle R, for the residuum. Hence the clogging' of the screen ,cloth c, .is obviated, back pressure of the' apparatus.;
avoided,- and a minimum of power only isY required to eect the successful working residuum receptacle, means for insurin SULGtwnmBe-QS My ap ara-tus is simple and inexpensive,
and vparticularly adapted to thevarying requiiements of household use, although I.do not confine myself thereto, since it is o'b-v vious that the essential features of my invention may be employed Wherever the collection of pulverous material is a desideratum, either on a large or a small scale.-
