VACUUM CLEANING-TQOL- Specification of Letters Patent. Patented Dec, 20, 1910,

Application filed February 14, 1910. Serial No.'543,813.

To all 'whom it may concern:

Be it known that L'HEXRY A. F nnotfssox, a citizen of the United States,- .residingat Louis. Missouri, haveinvented-a certain new and useful Improvement in Vacuum Cleaning-Tools. of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings. forming part of this specification, in which- Figure l a side elevation of a vacuum cleaning tool of my improved construction with a portion of said tool shown insection. Fig. 2 is a rear elevation of the tool'. Fig. 2-3 is a view looking against the under side of thetool.

My invention relates to a tool in the form of a'snction nozzle particularly intended for use in connection with vacuum or suction cleaning apparatus and which apparatus is used for removing dirt and dust from carpets, rugs, curtains, furniture and the like.

The principal object of my invention-is to construct a cleaning tool, which when moved over a carpet or the like will pick up all manner of lint, ravelings, hair and like fibrous material, and which fibrous material will be drawn into and through the tool with the suction of air passing therethrough.

To attain the object above noted I pr0- pose to arrange a series of teeth in the form of a comb. which teeth extend partially over the inlet slot of the tool and when said tool is moved over the surface of the carpet. said teeth will readily pass through the upper portion of the nap or pileof the carpet. thereby loosening the dirt and dust in said carpet and at the same time picking up ravelings. lint and hair, which objects readily pass from the teeth into and'through the tool.

To the above purposes my invention consists in certain novel features of construction and arrangement of parts hereinafter more fully described and claimed.

Referring by numerals to the accompanving drawing l designates the body of the tool which is approximately triangular in outline. and provided on its upper end with a socket 2 which receives the tubular handle 3.

Formed on or fixed to the lower end of the body of the tool is a plate through which is formed a longitudinally disposed slot 5 which communicates with the passage way 6. through the tool 1. Detachablv applied to the under side of the plate 41 is a face plate 7, the under face of which is slightly convex in cross section, and interposed be-' and formed integral therewith or fixed thereto is a series of teeth 12. which in form resemble the teeth of an ordinary comb, and these teeth project forward so as to occupy a position immediately over the rear portion-of the slot 9. I

The plate 11 occupies a recess in the face of the plate 7 which arrangement maintains the points of the teeth 12 in the same relative plane with the convex s wfi'ce of the plate 7 and the bearing surface of the plate 7, at the ends of said plate 11, prevents the points of the teeth of thecomhtrom digging into and tearing the nap of the carpet; The poi-ntsof the teeth merely ride or comb over the surface of-the carpet, or other ob] ect being cleaned, and all lint, ravelings, hair or fibrous material on the surface of the carpet will be picked up by the teeth of the comb and pass on to the upper surface of said comb from whence said material will be drawn upwardlyintoand through the tool 1 by the suction of air between the teeth of the comb.

lVhen the tool is in use the convex under side of the plate 7 is moved over the surface of the carpet, or other object being cleaned, and the points of the" teeth comb over the nap or pile of the carpett-hercby loosening the dirt or dust. in said nap or pile and picking up all lint, hair, ravelings and like fibrous material.

I prefer to arrange the plate ll and teeth 12 at a slight angle relative to a horizontal plane as shown in Fig. 1, although if desired the teeth can be arranged so as to occupy a horizontal plane.

In the construction of my improved tool I prefer to form the plate 7 of wood or hard and dust is drawn by suction. and a series of teeth occupying a plane substantially -at right angles to the direction of the flow of f air into the passage way. and which teeth extend partially across the mouth'of said opening.

' 2. The combination with a suction nozzle E provided with an inlet opening, of a seriesv of teeth projecting partially across the mouth of said opening.

3. A vacuum cleaning tool comprising a hollow body in which isfformed an inlet 1 slot,and a comb arranged on the under side i ol' the tool with the teeth of said comb projecting partially across the moat h of the slot.

el. The combination with a suction nozzle in which is formed an opening. ot a slotted plate applied to the underside of the nozzle,

and the underside of which slotted plate is" convex in cross section. and the slot in which plate coincides with the inlet opening and a series of teeth onthe plate which project partially across the slot in said plate.

5. The combination with a suction nozzle in which is formed an inlet opening. of a plate applied to the under side of the nozzle in which plate is formed a slot which coin- (ides with the inlet opening in the nozzle. and a comb applied to the face of the plate, the teeth of which comb project partially across the mouth of the slot in said plate.

in testimony whereof I hereunto atlix my signature in the presence oftwo witnesses. this 10th day of l ebruar 1910.
