DUSTING DEVICE Filed Sept. 25, 1925 Patented May 5, 1930 UNITED STATES HARRY A. INMAN, OF NEWARK, NEW/V YORK nusirnre DEVICE Application filed September 25, 1925. Serial No. 58,679.
This invention relates to devices for applying a film of dust or powder to work such as sheets or webs of paper or other material or objects which have been freshly printa ed or otherwise coated with a substance likely i to adhere to or be smeared by contact with other sheets or objects before drying, the chief object of the invention being to provide a simple and practical device of this character adapted to operate in an efiicient and reliable manner with a minimum of wastage of the dusting material and of attention from the operator.
To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described,thenovel features being pointed out in the claims at the end of the speciii cation.
In the drawings Figure 1 is a side elevation of an apparatus embodying the present invention and Figure 2 is an enlarged view of a portion of the same partly in section.
Similar reference numerals throughout the suchas described above has been found to several views indicate the same parts.
The invention is shown in thepresent instance, by way of illustration, as applied to the dusting of sheets of material while carried by a conveyor, the latter being suitable as a part of or an. attachment for a printing press, for example, but it will be understood that the invention is applicable as well to a variety of other mechanisms and uses.
In the present embodiment, there is shown a conveying mechanism comprising a frame having a pair of legs 5 at one end and at the other a pair of standards 6 serving as legs and also as upwardly extending supports for the dusting device proper. These legs or standards are interconnected by suitable cross members or braces as indicated at 7. Journaled between the upper ends of each pair of supports 5 and 6, respectively. are pulleys 8 and 9 carrying a conveyor belt 10. as shown, for sheets of paper, cardboard or the like 11. Pulley 9 carries on its shaft 9 one or more pulleys 12 rotated by a belt connection 13 with a motor 14 on the frame and serving to drive the conveyor belt and also a belt 15 ing means over the work.
for driving the dusting device 10mm on standards 6 above theconveyor as hereafter described. The conveyor as stated above maybe a part of a printing or other work producing mechanism or may be attached to the latter for receiving sheets at its right hand end and moving the same toward the left past the dusting device as shown.
Applying means are provlded 111 combination with the material container 16 for obtaining material therefrom and distributing or dusting the same over the work as the latter is carried past by the conveyor. A container function admirably with movable applying means of a character adapted to engage the dispensing wall portion 19 to gently vib "ate the same and agitate the material to cause it to sift through for distribution by the apply- It has been found also that such an applying means is admirably provided by a rotarybrush preferably 1 having flexible bristle portions of substantial length circumferentially in 'lhese bristles 20 are and spaced groups as shown.
mounted in any known or suitable manner in a. holder 21 having a. spindle 22 journaled at its ends in bracket arms 23 projecting hori zontally from standards 6 below thecontainer and over the conveyor as shown. Belt 15 is carried over an endof the brush or a pulley thereon to rotate the same. These parts are so proportioned and arranged that'bristles 20 during rotation engage fabric wall portion 19 of the container adiacent its bottom, as indicated in Figure 2, so as to gently vibrate the fabric, agitate the dusting material and cause it to gradually sift through. .At'the same time the bristles take up the material by contact therewith and with thefabric 19 and also cause a current of air which sweeps the dust downwardly into the path of the printed sheet or other work on the conveyor. The dusting material is thus kept in a finely subdivided form-and so distributed and dis pers d un-ifiormly over the entire suriaeepf the work and in quantities-which may be regulated to suit various conditions by selection of the fabric 19, by varying the speed of the brush 21 or its distance from and degree of engagement with the container wall portion 19, and the like as will occur to those skilled in the art.
The invention :thus provides a dusting device which the material is fed and ioarried which said material may be sifted, and a brush having spaced bristle portions and rotatable in engagement With said wall portion to agitate and sift said material therethrough, said brush being disposed in unobstructed relation to said conveying means for dispersing material obtained from said wall portion over the work carried by said conveying means.
5. In apparatus of the character described, the combination with work conveying means, of a container for a dusting material comprising a flexible, foraminous wall portion having a feeding inclination inwardly and downwardly to the bottom of the container and a r shi g device r ta abl n xterna eng m nt wi h id al p tion adjacent ts tt directly against the work. ltdesireda hood @0111 to agitate and si Said mat rial there- 24: may be provided and connected with an exhauster for carrying Oil and gsaluaglng the The device is simple in construction and adapted to operate reliably with a minimum of attention and its construction andmode of operation are such as to .aflord vefficient application of the .d-usting material with a minimum of wastage and dissipation oft'he Same in the surrounding atmosphere.
I claim as my invention:
