Specification of Letters Patent.

Application and February 9, 1912. Serial No. 676,567.

and also entered under low articles of furniture and the like.

The general objects of the improvement, and other ancillary advantages, are attained by providing a tubular handle with a cross tube on its end and making the nozzle in the form of two hollow conical sections having longitudinal slots in their under sides and having their bases swiveled on the ends of the cross tube; the nozzle sections being preferably joined by a hollow slotted yoke located in front of the cross tube.

A preferred embodiment of the invention,

I thus set forth in general terms, is illustrated in the accompanying drawing, forming part hereof, in which- 4 Figure 1 is a plan view of the nozzle with part of the handle; Fig. 2, an under side view of the nozzle with part of the handle; Fig. 3, a rear view of the nozzle with part of the handle; Fig. 4, a cross section of the nozzle and part of the handle on lines 4- 1,

Figs. 1, 2 and 3; and Fig. 5, a section on line 55, Fig. 1, showing one swivel joint.

Similar numerals refer to similar parts throughout the drawing.

The tubular handle 1 is provided jwitha cross .ube 2 on its end, the cavity of which communicates with the cavity of the handle, and in each end of the cross tube is provided a race-way for bearing balls 3, the rabbet 4 for the packing ring 5 on the outer side of the race-way, and the groove 6 for the packing ring 7 on the inner side of the race-way.

The nozzle is composed of two similar sections 8, the body of each of which is preferably formed as an elongated cone having the tubular head 9 formed on the inner larger end, which head forms thebearing socket 10 adapted to telescope over the corof the narrow portion of the responding end of the cross tube of the handle, and in which socket is provided the race-way 11 for the bearing balls 3; the swivel-joint thus formed being substantially co-axial with the sections. The lower sides of the nozzle sections are formed fiat and provided with longitudinal slots 12, the lips 13 of which are located in the same plane and are adapted to rest upon the carpet or floor to be cleaned, and the nozzle sections are preferably connected by the yoke-arms 14 which are suitably joined together as by the flanges l5 and the machine screws 16. The connecting yoke thus formed is preferably made hollow and, is provided with the longitudinal slot 17 in the lower side communicating with the cavity of the'end sections of the nozzle, thus making a continuous slot from one end to the other of the nozzle.

The slots in each end section of the tool and in the yoke-arms are preferably made of the same width excepting that the portion immediately adjacent to the swivel joint may be widened to form the enlarged opening 17 which is adapted to receive larger articles than can enter the ntirmal opening s ot.

The rearwardly-extending feet 18 may be provided on the tubular head of each nozzle section to prevent a rearward rotation Patented Sept. 15, 1914.

of the nozzlethe yoke-arms serving to prevent a forward rotation thereof-and these feet may be yoked together by the bars 19 which may be connected together by the flanges 20 and the machine screws 21.

By this construction and arrangement of the parts it is evident that the pointed ends of the nozzles can be readily introduced into comparatively small corners for cleaning .the same; that the handle, being swiveled to the nozzle substantially in the longitudinal axis thereof, may be rotated on such axis to bring the whole of the handle below the top of the tubular heads of the be entered under any article of furniture which will" receive the nozzle proper} and at the same time a continuous slotv is provided by which the tool is adapted to clean at all points between the ends thereof, like other tools of this character. And it is evident that the swivel or journal joint, thus nozzle sections, thus permitting the tool to formed between the cross tube of the handle and the tubular heads of the nozzle sections, permits the passage of dust or air either in or out of the nozzle in such a manner that no part of the bearing surfaces is ever exposed to the dust-laden air.

I claim:

1. A suction cleaning tool including a tubular handle having a cross tube on its end, and a nozzle having two approximately conical sections swiveled by their base ends on the ends of the cross tube substantially coaxial therewith, there being longitudinal slots in the lower side of the conical sections.

2. A suction cleaning tool including a tubular handle having a cross tube on its and, and a nozzle having two hollow sections swiveled by their inner ends on the ends of the cross tube and substantially coaxial therewith, there being longitudinal slots in the lower side of the hollow sections, and the hollow sections being joined by a slotted hollow yoke in front of the cross tube communicating with the slots and cavities of the hollow sections.

3. A suction cleaning tool including a tubular handle having a cross tube on its end, and a nozzle having two sections swiveled by their inner ends on the ends of the cross tube substantially coaxial therewith, there being longitudinal slots in the lower side of the nozzle sections, and feet on the rear side thereof.

4. A suction cleaning tool including a tubular handle having a cross tube on its end, and a nozzle having two approximately conical sections swiveled by their base ends on the ends of the cross tube substantially coaxial therewith, there being longitudinal slots in the lower side of the conical'sections, and the conical sections being joined by a slotted hollow yoke in front of the cross tube communicating with the slots and cavities of the conical sections, and there being feet on the rear side thereof.
