CHIMNEY CLEANER Filed Oct. 26, 1929 Q Q Q Q l fia/ZmZ Ve 6 I @V/ flaw/ Patented Sept. 16, 193% CHARLES 3:. NE'UMAN, F TIGERTON, 'WISCONSIN CHIMNEY CLEAN EB Application filed October 26, 1929. Serial No. 402,659;

My invention refers to chimney cleaners, and has for its object to provide a simple, economical, and effective cleaner, the arrangement and construction being such that the cleaner when inserted in a chimney is collapsed, and when drawn upwardly, under sudden reverse movement, will, by gravity, expand to cause a plurality of scraper bars to engage the four sides of the chimney.

With the above and other objects in view,

which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of' parts substantially as hereinafter described and. more particularly defined by the ap pended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the drawings, Figure 1 represents a side elevation of a chimney cleaner embodying the features of my invention, the same being shown expanded within the confines of a fragmentary portion of a chimney;

Figure 2 is a similar view of the cleaner in its contracted or colsed position;

Figure 3 is a detail cross section and enlarged view of the same, the section being indicated on the line 33 of Figure 2; and Figure 4 is an enlarged detail sectional elevation, partly in section, as indicated by line H of Figure 2.

Referring by character to the drawing, 1 represents a stem, to the upper end of which is secured a cable or runner 2, and the lower end of the stem is secured by a trip 3 to a spreader plate l. The spreader plate is provided with a peripheral series of apertures 5 grouped in rectangular form, the apertures being arranged to receive straight portions of flexible scraper bars 6. The lower ends or" the scraper bars terminate with transversely disposed fluted portions 6, which portions form contact brush elements for en gagement with the four walls or" the chimney. The upper ends of the scraper bars are formed with eyes which engage apertures 7, in a headed plate 8, said apertures being also formed in a rectangular group with reference to the centrally disposed stem 1, which stem is reciprocative in a central aperture 1; that is, formed in the head plate as best shown in Figure d.

The stem 1 is also guided reciprocatively in a slot 9 that is tormed in the crotch portion of a U-shaped hanger 10, the legs of which, as best shown in Figure 4:, are rigidly secured to the head plate 8.

Secured to the upper end of the stem 1 is a gravity release spring latch 11 having a flared nose 11', as best shown in Figure 2. The lat-ch is adapted to engage the crotched end. portion or" the U-shaped hanger 10, and under normal conditions this latch will hold the apertures in suspension upon the stem, whereby the flexible scraper bars are in their retracted position, as best shown in Figure 2 ot the drawings.

In operation, the cleaner brush as a unit is lowered into the chimney from above, in its contracted position, and when it is desired to cause the cleaner to function, a quick jerk upon tr e runner 2 by the operator, will release the head plate, scraper bars, and associated parts, whereby they will drop down by gravity upon the stem, and in so doing the spreader plate will ride upon the straight portion of a plurality of bars 6 to expand them to a position where their lower ends will engage the four walls of the chimney, and thus when the device is drawn up to effect a scraping or cleaning operation, these brush ends of the bars will thoroughly cleanse the walls of the chimney of soot or other foreign particles, it being understood that on the under-draw of the cleaner, there is a constant yielding pressure exerted upon said walls.

I claim:

A chimney cleaner comprising a stem hav- 9;) ng a spreader plate secured to its lower end, the plate being provided with a series of apertures bounding a polygon and grouped about the stem. a U-shaped hanger slidably mounted upon the stem with its bend at the upper end, a head plate secured to the lower end of the hanger, the head plate being provided with a series of apertures similar in position and number to the apertures in the spreader plate, but arranged to form a small- 1G0 er polygon, flexibl scraper bars each 'in piv otal union with anfap'ertur of the head plate" and ,p'ass'ingthrough a correspondling''aper- I ture in the spreader plate, each bar terminab 5 ing with a :scmping end; a spring catch Secured to the upper portion of the stem, the same being shapedto' engage the; upper. bend Collapsed When inserte'd in a chimnejgjand I expands incidexital to an'upwa r d jerk'of the stm. 1
