Definitions

  • This invention relates to dust collectors for pneumatic cleaners, and has for its object to im rove the efiiciency of separating the dust rom. the air, to simplify the disposal of dust when collected, to cheapen the cost of the dust collector and such further ob ects as may appear herein.
  • Fig. 1 is a diagrammatic view of a porous paper blank with a portion cut away to more clearly show a net-like reinforcement.
  • Fig. 2 is an enlarged view taken along section line AA of Fig. 1 showing two layers of porous paper and the net-like reinforcement.
  • Fig. 3 is a plan view of a finished dust collector.
  • Fig. 4 is a perspective view of a pneumatic cleaner with a dust collector of my improved type in position for attachment thereto and
  • Fig. 5 is a plan view of a wire collar fastener.
  • the numerals 11 indicate thin sheets of porous paper between which is placed a net-like fabric 2 such as cheese clothor tobacco cloth which has been treated with some adhesive and the sheets pressed together.
  • a net-like fabric 2 such as cheese clothor tobacco cloth which has been treated with some adhesive and the sheets pressed together.
  • the neck 5 is provided with a wire collar 6as shown in Fig. 5.
  • This collar is made from a piece of wire twisted together at -its ends 7 and provided with a loop 8, the purpose of which is to form Arm hold to enable the operator to 3- tighten the wire band when placed around the outlet 9 in the pneumatic cleaner, by twisting the loop 8 and thus twisting the wire at 10.
  • the wire band 6 is attached to the neck piece 5 of dust collector by turning up the pa er and supporting fabric and fastening it y either sewing or by an adhesive leaving the loop 8 projecting out of one side, thus forming a rounded edge which is adapted to fit into the groove 12 surrounding the outlet 9 of the pneumatic cleaner so that by twisting the loop 8 and the wire at 10 the band is drawn tightly around the roove 12 thus holding the dust collector rmly in place upon the outlet 9.
  • 13 is the 5 nozzle of a pneumatic cleaner, 14 the imsubstance.
  • the dust collector is provided at its upper end 17 with a'raised or rounded surface on each side, the top being left.open, so that the dust collector may be emptied when desired, but it is provided with a spring clip 18 or other well known means to hold the top in a closed position upon the handle 16, of the cleaner.
  • l1'are thin layers of por-' on ous paper and 2 is a net-like fabric attached to the paper layers by any well known adhe sive or by sewing them together. If an adhesive is used care must be exercised to prevent the adhesive from spreading over the porous layers of aper which would have a tendency to seal t e pores and thus prevent the passage of air therethrough. When so fastened together the porous layers of paper and the net-like reinforcement form one unit which is porous to air currents but retains dust and may then be made into a dust collector as previously described.
  • I preferably use two layers of thin porous paper between which is placed a layer of open work cloth such as cheese cloth or tobacco cloth.
  • This net-like fabric is treated with a cohesive substance in such'manner that the cohesive will not spread over the porous paper when placed between the sheets and subjected to pressure.
  • a dust collector adapted pneumatic cleaner, comprlsing a paper container porous to air, a net-like reinforcin member in contact with said container, an adhesive means ap lied to the strands only of said member latter to said container.
  • said bag being formed from paper porous to air, reinforcing means comprising a netlike cloth fabric attached to said bag by an adhesive, said adhesive being applied only to the paper at the point of contact with the v strands of the fabrlc whereby to leave said porous paper free 0 adhesive between the strands of said fabric.
