'PURIFIER AND AERATOR.

SPECIFICATION forming part of Letters Patent No. 530,445, dated December 4, 1894.

I Application filed February 13, 1394. Serial No. 500,056; (No modeL) To all whom it may concern: 5 Be it known that we, JAMES NEWBY and THoMAs F. N EWBY, both of Harrisburg, in

sorb more water in baking;

the county of Dauphin and State of Pennsylvania, have invented a new and Improved Purifier and Aerator, of which the following is a full, clear, and exact description.

Our invention relates to improvements in that class of machines which are used especially in connection with flooring-mills to separate the dust, fluff, &c., from middli ngs, break-stock and other flour stock, and in that class of machines used to aerate flour or flour stock; and the object of our invention is to produce a simple and inexpensive apparatus designed for such purposes, which apparatus uses air taken from beyond the walls of the building, purifies suchair by straining through cloth and handles such pure air in a way to remove from the stock acted on thereby, the dust, fluff,and impuricools and bleaches the stock, causing the stock to bolt more freely in the mill, and in case of'fiour, causing it to pack better, keep better and ab:

being adapted to act on a continuous stream 7 of stock as it is passed through it.

To these ends our invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure l is a sectional elevation of theapparatus embodying our invention. Fig. 2 is a sectional plan on the line 22 of Fig. 1. Fig. 3 is a vertical sectionon the line 3-3 of Fig. 1,showing in detail the arrangement of the first dust chamber where the outside air 1 is admitted and purified. Fig. t is avertical section on the line 44 of Fig.1, showing the arrangement of the second dust chamber and the conveyer for carrying away the dust and fluff; and Fig. 5 is a detail sectional plan on the line 5-5 of Fig. 1.

The apparatus is provided with a main case 10, which may be of any approved construction and which has a hopper-like bottom 10 terminating in a discharge spout 10".

the apparatus.

The case is supported on a suitable framework 11 and 'at one side of. the case is a purifier 12 which has an inlet pipe13 deliv ering into a space 14 at the top of it, this pipe 13 being adapted to extend through the building in which the purifier is located and to receive its air supply from outof doors.

Inthe central portionof the purifier case is a series of vertically arranged cells 15', made of cloth, through which the air may pass these cells being supported on suitable cross bars 16 and 17 at their upper and lower ends, and thus a plurality of narrow channels,'open only at the top and bottom, is

is a dustchamber 18, in which the dust may settle, and access to the main case-and to the dust chamber is had by means of

doors

19 and 20."

The air is drawn from one side of the purifier 12 through a pipe 21, by means of a fan 22 of ordinary construction, which is carried by a shaft 23 beneath the purifier, this shaft having a suitable drivingpulley 24, although any means may be employed for turning it. The fan causes the air to rush in through the pipe 13 and down through the purifying cells 15, to the cloth of which the dust, smoke, and

other impurities stick, so that the air which issues from the purifier passes to the main case freed from all impurities, cooled and in condition to have the most beneficial effect on the stock with which it comesin contact, as specified presently.

By reference to Fig} 3 it will-be seen. that the cells 15 hang downward in thepurifier case 12, air spaces being left at the sides so that the air passes through the cloth of the cells and down through the pipe 21, while the dust which drops from the cells collects in the chamber 18.

The air exhausted from the purifier by the fan 22 is deliveredinto the lower portion of the main case 10 and through a pipe 25, which has anupturned end 26 which is closed at the top and in the sides .of which are ports 3 27 through which the air passes, these ports being arranged circumferentially around the upturned end of the pipe so that the airissues from all sides thereof, as indicated by the arrows in Fig. 1. Above the pipe 25 is a pure air and is thoroughly dried, cooled, and

separated from the dust, fluff, &c.

The stock is fed upon the deflecting plate from a chute 29 arranged vertically in the case 10 and enlarged preferably at its upper end, as shown at 30. A continuous stream of stock is delivered into the chute from the feed spout 31 above the case. In the lower end of the chute 29 is a vertical revoluble shaft 32, carrying radial arms 33 which serve as agitators and distributers and cause the stock to drop suently upon the deflecting plate 28 and fall evenly off its edge. It will be seen that this arrangement spreads the stock so that the air has the best possible chance to strike every particle of it.

The shaft or spindle 32 of the agitator and plate has, at its lower end, a pinion 34 which meshes with a pinion 35 on a horizontal shaft 36, which shaft is held in a suitable casing 37 and projects outward through the main case 10, and it is driven by a belt 37, from the shaft 23, as shown in Fig. 2, but such shaft or spindle 32 may be driven by any suitable means. Leading from the upper portion of the case 10 is a pipe 38, which connects with a fan 39, and the discharge pipe 40 of this fan delivers into the dust collector 41 which comprises a case and cells therein, located preferably on the side of the main case opposite that on which the purifier is arranged.

The fan 39 draws the dust, fiuff and other matter from the case 10 and discharges it into the dust collector 41. The dust collector is very similar in its arrangement to the purifier 12 already described, and is provided with slotted sides 42 through which the air may escape. The dust collector has within it a frame 43, which is arranged near the top and is suspended on bolts 44 which project through the top of the collector case and have thumb nuts 45 thereon, so that the tension of the cells 46 suspended from the frame43 may be conveniently regulated. Any other suitable means may be employed for regulating the tension of these cells, which are identical in their construction with the cells 15 already described, and which, at their lower ends, are attached to a freely moving frame 47 which is normally pulled down, so as to hold the cells taut, by spiral springs 48 attached to the frame 47 and to supports beneath it, but any equivalent things may be substituted for the springs.

Extending transversely beneath the frame 47 is a shaft 49 on which are cams or equivalent vibrators 50 which turn against the frame 47 and which, by so turning, cause the frame to vibrate vertically, thus constantly shaking the cells 46 so as to shake the dust and fluff 0d of them, while the air passes out freely through the slots in the side of the case. The shaft 49 may be turned in any convenient way, but as shown, it is driven by a belt 51 extending from apulley on the shaft to a pulley on the conveyer shaft 52 below it, which shaft is provided with a pulley 53 to which a driving belt 54 may be attached. The dust collector has a hopper-like bottom 55, through the lower portion of which extends transversely the conveyer shaft 52, which has the ordinary screw blade 56 thereon, and the conveyer delivers into aspout 57 which may be made to discharge into any suitable receptacle so that the dust, fluff, &c., which settles in the collector, is constantly discharged.

It will be seen from the above description that a continuous stream of stock may be delivered into and discharged from the main case 10, that pure cold air is constantly applied to the stock, that the fluff and dust is eifectually separated from the stock, and that this fluif and dust is automatically collected.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1.
