. VACUUM CLEANER FOR BARBER CHAIRS Filed March& 1948 Patented Mar. 25, 1952 UNITED STATES;- PATENT OFFICE 2,590,673 VACUUM CLEANER FOR BARBER CHAIRS Charles E. Bezanson, Malden, Mass.

Application March 8, 1948, Serial No. 13,626

3 Claims. (Cl. 155-188) My present invention relates to vacuum chair to be raised and lowered without interfering with the operation of the vacuum sweeper.

Still another object is vacuum sweeper attachments for a barber chair which maintains the throat piece of the vacuum sweeper under the foot rest of the barber chair regardless of the movement of the chair, and

Other novel features comprising the construction and operation of my invention will appear as the description of the same progresses.

Referring more in detail to the drawings:

Fig. l is a fragmentary side elevation with my invention attached;

Fig. 2 is a fragmentary cross-section taken on the line 2--2 of Fig. 1, portions being broken away for convenience, and

Fig. 3 is fragmentary cross-section taken on the line 3-3' of Fig. 2 showing rotary electrical contact rings etc.

Referring more in detail to the drawings, Ill indicates a fixed pedestal of a barber chair and II indicates the movable portion which elevates and lowers the chair portion I2. Barber chairs are usually operated by hydraulic means which have been eliminated from the present drawings as having no bearing on the present invention. I3 indicates the foot rest of the chair which moves up or down and swings with the chair portion I2, dot-dash line indicating an elevated position.

To the fixed pedestal portion I I have attached electrical contact rings the fixture comprising an outer shell which may be split at I5 and clampedtogether with bolts I6 or attached in any other suitable means. Within the shell I4 are located insulating rings I1 and I8. The insulating ring II is fixed against rotation in the shell I4 and has imbedded therein an electrical ring I9 of copper or other electrical conducting matter. The ring I9 is directly connected at with an electric current supply source. Directly above the ring I9 is a similar ring H which is imbedded in the insulating ring I8 and in engagement with the conducting ring I9. Electric current is transmitted from the ring 2| through the conductor 22 to the vacuum cleaner 23'. The

throat piece 24 of the vacuum cleaner 23 is located under the foot rest I3 of the chair I2 and has a tube '25 extending up behind the supporting 1 It will thus be seen that the chair I2 and attached vacuum unit 23 can be raised or lowered without raising or lowering the throat piece 24. At the same time the chair and vacuum unit 23 together with the throat piece 24 may be rotated and the electric contact ring 2| being in contact with ring I9 will supply electric current to the vacuum unit 23.

The throat piece 24 is adjusted to the proper height from the floor and remains there regardi less of the position of the chair cleaning the floor in the base pedestal, a chair solidly supported at 'sulating ring fixed about the base pedestal and back 2610f the foot rest I3 and tightly engaged in member 21- fixed to the rotatable insulating ring I8. Telescoped in the throat member tube 25 is a slidable tube 28 which directly connects to the vacuum'sweeper unit 23.

the upper end of the post, in combination with vacuum sweeper means secured to the under side of the chair, electrical conductor means for connecting the vacuum sweeper to a source'of power, a suction inlet member constituting of a throat piece responsive to the vacuum sweeper to draw material therein, said throat piece being supported in a position of fixed vertical spacing relative to the bottom of the pedestal, and telescoping tubular connections located between the vacuum sweeper and the throat piece to provide for maintaining the latter member in its said fixed relationship to the bottom of the pedestal when the vacuum sweeper and chair are raised and lowered into various positions of adjustment in the said pedestal.

2. A device according to claim 1, in which the electrical conductor means includes a lower in an. upper insulating ring arranged for rotation relative to the lower insulating ring.

3. A structure according to claim 2, and further including supporting bracket means fixed onzthe upper insulating ring in a position to hold the throat piece in radially fixed relation to the .axis of the pedestal in a raised position with respect to the bottom of this member infall positions of rotation of the chair about the pedestal.
