VACUUM CLEANER NOZZLE.

APPLICATION FILED DEC.5. I912.

' Patented July 25, 1916.

UNITED STATES ABRAHAM L. FRAME, OF READING, PENNSYLVANIA.

VACUUM-CLEANER NOZZLE.

Application filed December 5, 1912.

To all whom it may concern Y Be it known that I, ABRAHAM L. FRAME, a citizen of the United States, residing at Reading, in. the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Vacuu1n- Cleaner Nozzles, of which the following is a specification.

This invention relates to vacuum cleaner nozzles, the object of the invention being to provide an improved. nozzle readily constructed, simple in such construction and easily operated as we l as one which is durable in use and which will also have con siderable efficiency in operation.

In the drawings accompanying and forming part of this specification, Figure 1 a bottom plan view of this improved nozzle; and Fig. 2 is a crosssectional View taken in line 2-2, Fig. 1.

Similar characters of reference indicate corresponding parts in the figures of the drawings.

This improved nozzle, in the preferred form thereof comprises a chambered head 2 having a nipple 3 located substantially centrally of the curved. wall 4 ol' the chem bored head for the reception oi? the usual tubular handle 5. The chambered head. which is usually about an inch and a quarter in width. has curved end Walls 6, and projecting from its opposite side walls throughout the length of the head and at the bottom of the head in position to com tact with the surface to be cleaned is a ries of inwardly extending projections 7 lo cated in the present instance one opposite to the other. These projections are shown as oi slightly tapered form with curved edges and form at opposite si os of the head a series of teeth or prmigs having curved edg s, so that the opening 9 into the chamber will he of an irregular form living less adjacent to the opposed ends of the prongs than at those points intermediate such prongs Whercny the area of openin' into the nozzle is very much larger than would he the case if it were simply a. straight slot extending from end to end. thereof. At. the ends of the nozzle this ir-- regular opening terminates in a pair of approximately semi-circular openings it}.

By reason of the present construction the Specification of Letters Patent.

Patented July 25, 1916.

Serial No. 735,016.

the nozzle, while the area of such opening is kept well within proper relation to the amount of vacuum which the machine is capable of producing, thereby materially increasing the efliciency of the nozzle. In other words, while the area of the opening is increased, thereby enabling such opening to cover a larger area of the surface to be cleaned than would be the case with a flan row inlet slot of the same length f uniform width throughout. such i'icreasen area is obtained in such a manner that the suction effect at the nozzle is not impaired.

I claim as my invention:

'1. A vacuum cleaner nozzle comprising a chambered head. provided in its bottom surface with a single inlet opening having tortuous side walls forming a series of elliptical openings connected by narrower 0penings of oppositely curved formation.

A vacuum cleaner nozzle comprising a chambered head provided in its bottom surface with a single inlet opening having tortuous side walls forming a series of elliptical openings connected by narrower open ings of oppositely curved formation. the opening at each end of said nozzle being substantially scmimircular and also connected to its adjacent elliptical. opening by one of said mirrowcr opeiizings.

55. A vacuum cleaner nozzle comprising a chambered head liming a bottom plate pro- Yidcd. midway of its length with an clon gated slot having all along its length oppositely extending openings forming a series of inwardly extending projections.

4 A vac-mun cleaner nozzle mmprising a chambered head having a bottom plate provided midway of its length with an elongated slot having all along its length oppositely extending openings forming a series of inwardly extending projections, said uppositely extending openings forming trans verse elliptical openings in said plate.

A vacuum cleaner nozzle comprising a chambered head having a bottom plate providcd with a series of equally spaced alter nate openings and projections forming a pair of tortuous side Walls with the projections spaced apart midway of the length Signed at .R-ending, Pennsylvania, this of the nozzle thereby to form an elongated 30th day of November, 1912.
