, Specification of Letters Patent.
Application filed January 18, l1911. Serial No.; 603,251.
To all whom it may concern: f
Be it known that'I, FRANKLIN F. BRAD- LEY, citizen of the United States, residing at Chicago, in the county ofp-fCo'ok and State of Illinois, haveinvented a 'certain new' and useful Improvement in Apparatus for Coat'- ing Objects with Subdivided Material, 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 v p My invention relates to apparatus for coating objects with comminuted, subdivided or powdered material and is, ofparticular-` servicein `spreading bronze `powder upon objects whose surfaces to be coated are'cov'- ered or paintedf with suitable adhesive material or paint, which in its fresh state holds the powderscattered thereupon and in'its dry stateufirmlyfixes the powder in place.
I have liled other 'applications relating to apparatus for coating objects with subdivided material as follows: Serial No. 543,215, filed Feb. 11, 1910; Serial No. 550,115, filed March 18, 1910; Serial No. 569,428, filed June- 29, 1910; Serial No.` 588,730, led October 24, 1910; Seriali No. 588,731, led October 24, 1910; Serial No. 603,726, led January 20, 1911; Serial No. 609,203,.led Februaryfl'?, 1911. Inmy ap-x plication Serial No.609,204, filed FebruaryV 17, 1911, I have claimed my novel method of coatingobjects with subdividedmaterial.
In practicing my invention I employ a' receptacle fhaving a door-way or opening through which theobjects to be coated may" be passed into the receptacle interior in position to enable the air to be circulated around and toward the obj ects, the opening" sides in a fan whose blades are so formed Patented Apr. `4., rari@ and arrangedv as to cause'the air to be 'moved' from and` toward the fan 'in a circuit or stream, the fan which I employ being thus 'distinguished fromthose fans` `whose 'blades merely 'serve to churn the airwithout imf'l'v4 'partin any general 'movement' thereto.
' I wi explain my 'inventionmore fully by leo reference tothe accompanying drawings showing la i and in which'.- v
preferred' embdiment thereof., ,i
Figurel 1 .is 'a side elevation, partiallybroken away, fof a receptacll'ea'nd contents, .means'for supplying the subdivided yinate-fA rial to'the receptacle beingshown at-the'left thereof; Fig. 2' is'. a sectional view on line' perspective; of vthe shelving 'as it preferably view showing a nozzle structure plan asl '2 2 of Fig. 1; Fig. 3 iis a'detail view, in 'i yenters into the structure; 4`is'a"detailA it appears in Fig. 1; Fig. 5 is an end View", A'

Like parts 'are -indicated "by similar!'cliarcters ofreference throughout thediiferent .Y gu y ,a i The receptacle a is preferably made of sheet metal and incloses' air' circulating mechanism which is desirably in` the form' of .an electric motor 'driven fan' b, laterto'be more fully 'describedl '.Thereceptacle ha'sa door a1 which is openedl when the objects'are to be inserted within the receptacle interior and` which is closed'when' the objects are to be coated. The receptacle' 'is suitedl in size and shape tothe objects that areto'be placed therein lfor thel purpose of having subdivided material lodged thereupbn, the loca;- tion of the fan' I) within the receptacle perclosely to the object or 'objects that arey to be`- 3 inserted therein for'the purposestated,` this" close correspondence ofthe vreceptacleV and ceptacle a. y
f' The receptacle is providedlvwnith' shelving" d three I'distinct shelves being shown, `the shelves outsettlng from themamv-casing wall" y i. K In order not to- `interfere with the insertionf VIon of theobjects to be coated andforniing ythe Vbottom `of channel ways extending along a 9o mitting .the receptacle tol conform' very side of the receptacle, and completed by means of vertical portions e and top portions f. The channel ways are separated from the balance of the receptacle space by means of screening g provided for the purpose of preventing large particles from finding access to the object to be coated. The bronze powder may be placed upon one or more of the shelves, and if it is thus placed while the fan b is in operation all of the channel ways except the one within which the powder is being inserted are closed as by' means of plugs h. The powder may be inserted within the channel ways in a manner which is most desired. I have shown a nozzle a upon the end of a pipe 7c through whichr the bronze powder may be forced. The nozzle z' and pipe k are here shown in the form of a pipe of which the nozzle constitutes an elbow rigidly related with respect' to the balance of the pipe, although I do not wish to be limited to this characteristic: If the powder is forced gently through the pipe 7c the pipe is turned ,to enable the nozzle z' to face a shelf d, whereupon the powder may be laid upon the shelf and thereafter removed therefrom by the operation of the fan b. lf the powder is forced through the pipe under considerable pressure. the nozzle z' would be turned to occupy a horizontal position, such as is indicated in Figs. 1, 2 and 4, whereupon the powder may be directly injected without first finding lodgment upon the shelf, and by moving the nozzle back and forth the powder may be suitably distributed within the receptacle. I have illustrated a supply box Z thatcontains the bronze powder m and from which the bronze powder may be forced through the pipe 7c when the valve n in a flexible air pressure pipe o is open. The box Z may bel carried in the hands so that it may be moved toward and from the receptacle and also turned thereby to determine the places at which the powder will find entry within the receptacle. In the event of its being desired, the excess of the subdivided material which remains within the receptacle `after the object has been coated may be withdrawn by a suction fan p when set into operation, the excess powder finding lodgment within a collection box g to which it is passed by the suction fan. A damper p1 is desirably employed for open` ing and closing communication between the exhaust fan ,u and the receptacle interior.
The blades of the fan are shaped or disposed to act as component parts of a screw tocause the fan, when properly rot-ated, to force the air to move from it, as indicated by the arrows b1 in Fig. l, the blades of the fan forcing the air to move'in a comparatively definite direction from the fan and causing the air to be drawn to the fan in a comparatively definite direction as indicated by the arrows b2 in Fig. 1. The fan b thus causes the air where it has fullest flow, to follow a circuit or stream which is determined by the construction of the fan, the fan forcing movement of the air toward the wall opposite it, this wall and the other walls of the receptaclel cooperating with the fanin delining the circuit that the air is to follow whereby the material with which the air is laden is properly carried to all exposed parts of the objects that are to receive a coating. By employing the fan which does not merely churn the air but which is effective in defining the ath that the air is to follow, a comparative y small fan may be employed, it being obvious that a fan that merely churns the air would have to be of very large proportions even to approach the results which are secured with the aid of the fan illustrated.
While I have used the term air throughout the specification and claims, '1t is obvious that any inert elastic fluid may be used and I use the term air in the claims in this broad sense. l
While Iprefer a fan t of the precise construction shown for accomplishing the results which are the object of my invention, I do not wish to be limited to this instrumentality within the receptacle for dening the general path followed by the air'where it has fullest flow, and while the blades of the fan are, by reason of their entire location within the receptacle, adapted to effect vreturn movement ofthe air to the fan, I do not wish to be limited to this characteristic.
Having thus described my invention, I claim as new and desire to secure by Letters Patent the following 1. Apparatus for coating objects with subdivided-material carried by air including a receptacle for the objects; and fan` mechanism within the receptacle constructed to effect the forced passage of air in a stream within the receptacle toward and from the fan in order to carry the material with which the air is laden to exposed part-s of the object that are to receive the coa-ting.
2. Apparatus for coating objects with subdivided material carried by air including a receptacle for the objects; and mechanism within the receptacle constructed to effect the forced passage of air in a stream within the receptacle toward and from the mechanism 1n 'order to carry the material with which the air is laden to exposed parts of the object that are to receive the coating.
