nnoxup application I v The combination of an air suction device with means .for dislodgingmateri'als which ma be drawn into the apparatus; 7 7

he attachment to avacuuincleaner of a brush mechanism actuated iconjointly with the suction pump of the vacuum ap aratus;

A novel combination of brush mein ers and suction apparatus whereby, foreign matter loosened by the brushmaybecpnveyed into a receptaclefor such matter attached to said suction apparatus; and .11 1 A new article of manufacture. comprising a vacuum cleaner apparatus and brush mem bers combined therewith for-increasing the eiiiciency and scope of operations of the vacuum cleaner, v These, and such other objects as may hereinafter appear are attained by the novel combination, construction and arrangement of the several elements which constitute the in-- vention, one embodiment of WhlCh 1s 1llustrated' in the accompanying drawing, in

which- 1 V J Figure 1 is a schematic arrangement of the device, the parts generally shown in elevation I Figure 2 is a longitudinal section; and

Figure 3 is an end view.

Like reference characters are used to designate similar parts in the drawin and in the 40 description of the device which ollows. of the device is shown as 15.

Only so much required to illustrate its novelty. As the device is capable of employment upon different types of vacuum cleaners and has nothing to do with the internal structural arrangement of the vacuum cleanser proper, an illustration of such a cleanser is omitted from the several figures hereinabove described.

' Comprising, as it does, an apparatus de- 5 signed for cleansing carbon deposits from Diesel and internal combustion engines, it

must be borne in mind that the structural arrangenient of the embodiment may be modified. to suit the special work for which the apparatus is to be used, and therefore, the

tube

10, 13, is of a truncated cone configurat1on'or- 5 funnel-like in its appearance. sec-- ti'on 13 is disposed a stem or spindle 14driven' by cable 12. A thrust bearing 14 on the inner end of spindle 14-. prevents longitudi- I nal movement ofsaid. spindle.

The brush members 15. com prise bristles of steel'wire which bristles are adapted to cleanse metallic or other-surfaces coated with foreign materials and held thereto by oil, grease or otherviscous deposits.

The reference numeral 16 refers "to a schematic illustration offthe usualportions of avacuum cleaner includin the ordinary dust trappingba motor and t e like.
