OF DETRGIT, MICHIGAN SMOKE PRECIPITATNG APPARATUS Application led June 15,

My invention relates to a new and useful smoke precipitating apparatus and particularly adapted for use in precipitating coal smoke.

The invention is so constructed as to o erate so as to utilize the` discharging e `ects of pointed surfaces of bodies vpossessing a. high electric charge. It is known that by equipping a chimney or other passage-way of smoke with a plate and discliarging'points positionedopposite thereto and a proper diS- tance away from the plate and that by charging the apparatus to a high potential, precipitation of suspended particles from smoke l5 can be brought about. However, when the plate becomescovered with soot, the apparatus becomes ineffective and it is to overcome this disadvantage which is one of the objects 20 of the present invention.4

vision of a smoke precipitating apparatus of thisaclas's which will be simple in structure, economical of manufacture and highly eihcient in use.

Another object of the invention is the provision of a device which may be easily and j quickly installed, inexpensive to operate and compact in its structure.

Other objects will appear hereinafter..

The invention consists inthe combination and arrangement of parts hereinafter described and claimed.

The invention will be best understoodby a reference to the accompanying drawin 35 which forms a part of this specification an in which,

' zontally extended shaft 13 which projects through insulating bushings 13 mounted in the

23 and 24^of a housing. Mounted so as to permit the shaft 13 to project therethrough is a housing having walls 15 and 18. 65 Projecting inwardly from the wall 15 is a cylindrical bracket 14 in which is pitioned a spring 16 engaging a brush 20. A similar brush 21 is in engagement with the spring 19 positioned in the cylindrical bracket 17 im which projects inwardly from the housing wall 18. 1n the lower part of this housing 1 have oil or a like liquid. Fixedly mounted on the shaft 13 so as to engage between and be engaged by the brushes 20 andI 21 is a disc 5 22. The wall 24 of the housing is inwardly set as at 25 and provided with a vertically extending continuation 26. A neck 28 projects upwardly from the upper wall 27 of the housing embracing which is the conduit or Hue 29 70 leading tothe blower 30, this blower being operated by the electric motor 31. Fixedly mounted on the shaft 13 interiorly of the housing having the

walls

23 and 24 is a disc 32. An insulating plate 33 serves to insu- 0 late the metallic plate 34 from. the wall 26.- Projecting outwardly from one face of the plate 24 so as to lie horizontally are metallic contact members or pins 36, preferably formed from wire, these pins projecting through the layer of insulation 35 which may be formed :from asbestos wool or other 'suitable insulating material. Formed in this layer 35 is a cavity 37 in which is positioned 85 the enclosing housing' 38. Projecting inwardly-from the housing wall 24 are

brackets

39 and 40, each of which is constructed simi. larly. A slot 41 is formed in each of the brackets, these brackets being provided with channels 42and 43 as appears in Fig. 1 and Fig. 4'. Engaging in the channels 43 and42 are

trunnions

44 and 45, respectively, which project outwardly from the bearing 46 in which is journalled the shaft 47 of the roller 95 brush 48, this roller brush being held by the springs 46 in engagement with the face of the disc 32. This brush is rotated by the flexible shaft 109carrying the gear 110 Whlch meshes with the gear 111 on the motor 68. 100

A simllar sealing block 52 is positioned around the imsulating member 35. -A conduit 53 which 75 serves as a flue or chimney is divided into a pair of branches 54 and 55 which communicate with the housing through the

necks

56 and 57. Mounted in the lue 53 is a door 105 which is kept closed by the action of an 80 electromagnet. In case the power should be accidentally cut off the electromagnet will release the door. Springs set for such purpose will push it wide open. The motive of such outlet is to give a way out to the smoke for the time the power is olf and the blower still. The wires 58 and 58 and 59 connect to a suitable source of electrical energy and lead to the transformer 60 which is electrically1 connected to the converter 61 which serves to 90 5 transmit direct current to the discharge points through a wire 62. A wire 63 connects this converter to the brushes 20 and 21 through the disc or plate 22 to the plate 32. The

motors

68 and 31 are connected to the source of 95 electrical energy in the usual manner.

The motor 68 is connected by the belts 69 to the pulley 70 which is ixedly mounted on the shaft 13. The

motors

31 and 68 are wired as to the mains in the regular way. A iexible shaft connects the rotary brush to the motor 68. Where a large machine is used a small motor may be used exclusively to rotate the brush, thus doing away with the flexible shaft.

o In operation, as Vthe smoke is delivered up 105 the chimney 53, the electric charge will cause a deposit of the smoke over the disc 32. As the disc 32 is rotated upon a rotation of the shaft 13, the brush 48 will serve to prevent 4.5 accumulation of soot on the disc 32, thus prou no viding an eicient operative device at all times. l

While I have illustrated and described the w preferred form of my invention, I do not wish to limit myself to the precise details oi structure shown but desire to avail myself of such variations and modifications as come within the scope of the appended claim.

u Having thus described my invention, what no I claim as new and desire to secure by Letters Patent is:
