tion of the invention, such as'will enable others skilled in the art to which it appertainsto make and use the'sainej My invention relates to improvements in chimney cleaners and the object of my invention is to provide a simple, cheap, and easily operated device by means of which chimneys may be easily cleaned bypassing a pneumatic apparatus from the bottom to the-top thereo With this object in view my invention consists in" the construction and combinations of parts as hereinafter described and In the accompanying drawings :Figure 1 represents a section of a chimney showing -able means. This hose is connected witha the manner of using my invention therein. Fig. 2 is a perspectiveview of a different form. of blowing head, showing the preferred arrangement. Fi 3 .is' a section taken centrally through e form shown in Fig. 2. Fig. 4 is a perspective view ofsthe supporting fork, by means of which, in connection w th thetjointed rod, the apparatus maybe lifted. up through a chimney.

0 represents a flexible pipe, such as a rubber hose, which is directly-attached to the lower end of the blowing head by any suitblower b of. any desired type which is driven by any desired form of motor 0, a small electric motor being shown in the drawing,

, adapted to rest on an ordinary table.

d, Figs.'2 and 3, represents ahollow blowing head generally shapedlike an inverted bowl having its lower end open." To the end of the pipea is fitted a flaredconnecting piece 6 which furnishes a means for holding the lower .end of. the bowl- 0', in position but allowing it to revolve freely thereon. a

7 represents a {ring attached to or formed integral with the part, e and against which the'lower end ofth'e bowl rests, being confined thereon between the ring f and the flaringpart g of the pa'rt e. Thisring f is provided with eyelets h or similar fastening means.

Of course, any su table means for sup Specification of Letters Patent. Patented Aug, 23, 1910, Y Application filed Na;' 7, 1909. Serial No, 494,644.

porting the blowing head at on or just above the end of. the flexiblepipe a, which will allow the head at to freely rotate, may be 'wardly through the top of the bowl, as

shown in Figs. 2 and 3.- These vanes are ofa peculiar shape, best shown in Fig. 3, being'hollowed out as shown at is, and'having projecting curved sides m and n. vanes are outwardly divergent and reversely arranged and have air passages in their concave faces, leading outwardly through the head. The object-of this construction is to cause'theair which is forced under considerable pressure through the pipe (1 to be delivered through the grooves lcof the parts 3' in a set of diverging jets which impinge on the inner wall of the chimney and which These cause the head 03 to revolve thus insuring a thorough cleansing of the chimney as the blowing head is slowly pulled up or raised. As many .of'these parts j may be used'as desired. .3

The apparatusmay be jpulled up by mean's of a rope attached to the ring .2. Instead Iv however, of pulling the blowing device upwardly may be lifted in the following manner: w inFig. 4, represents a fork provided with pointsy adapted to engage in the rings h. The lower part of this fork is provided with a reduced portion a which is adapted to fit onto the itop 'section of a jointed pole. Thus the apparatus may be Slowly'lifted from time to 'time by adding successive joints to the pole, these joints be-' ing preferably screwed together.

What I claim is:;

which said flexible pipe is attac ed, and a blowing head rotatably mounted on 'said' rigid pipe, ,said head being provided with curved concave vanes projecting outwardly from the interior thereof and air passages provided adjacent saidvanes, sub.

. v 1. The combination of a-Jolower, a flex: -ibl e pipe connected thereto,"a ri' id pipe to flexible pipe-is attached, and a hollow blowing head rotatably mounted on said rigid pipe; said head being provided with concave vanes outwardly divergent and reversely arranged, air passages being provided from the interior of said head along the cavities of the vanes, substantially as described.

3. The combination of a blower, a flexible pipe connected thereto, a rigid pipe con nected to said flexiblepipe and provided with an eyeleted ring, a blowing head rota tably mounted on said ring, and provided with concave vanes, said vanes being out- 'wardly divergent and reversely arranged,

In testimony whereof, I afiix my signature, in presence of two Witnesses.
