Feb.'4, 1936. l.. F. MCCARDLE SUCTION NOZZLE OF VACUUM CLEANING APPARATUS Filed May 51, 1954 NEY- HIS ATTO Patented Feb. 4, 1936 PATENT OFFICE SUCTION NOZZLE F VACUUM CLEANIN APPARATUS Lionel Frank McCardle, Durweston Mews,
, England Application May 31, 1934, serial No'. 728,452 In Great Britain March 2, 1933 Claims.
This invention relates to vacuum cleaning apparatus and more particularly to suction nozzles therefor which are adapted to be moved by a handle over the surface of the carpet, for example, to be cleaned, the lower surface of the nozzle being formed with a nozzle opening including a recess that communicates with the suction hose whereby the dust, nui, hair and other matter is extracted from the carpet and drawn throughl the hose into the bag or dust container.
The object of the present invention is to provide an improved construction which provides for the thorough cleansing of the surface of the carpet, all matter that is apt to cling thereto such as cotton yarn, hairs, and fluff being effectively removed.
A further object of my invention is to provide an improved construction in which a brush is enclosed within a nozzle and so arranged that the brush is adapted to be moved into contact with the surface to be cleaned.
A still further object of the present invention is to provide an improved nozzle which is divided into two parts one of which is movable relatively to the other and each of which in itself forms an effective nozzle.
It is known to enclose a brush within a suction nozzle and to arrange for the brush to be adjusted toward and away from the surface to be cleaned. According to the present invention, the brush is normally held back by springs from that surface, for example a carpet. Pressure downward on the handle, however, will bring the brush into contact with the carpet.
In a preferred embodiment of the invention, an auxiliary suction nozzle is flxed alongside the brush and is arranged to movev therewith within the main suction nozzle. A more'concentrated suction is thereby provided along the brush when this is depressed into operative position.
llf it is desired one or more apertures vmay be provided in the main suctionnozzle to permit air to enter the nozzle and to pass through the brush to increase its effectiveness and t keep it clean.
But in order that this and other features of the invention may be clearly understood reference should now be made to the accompanying drawing in which similar-reference characters relate to like parts in all' the figures and in which:
Figure 1 is a plan of the double nozzle as viewed from the top and 4 Figure 2 a plan viewed from below,
Figure 3 is a longitudinal section on the line A-B Figure 1, and
Figure 4 a cross section on the line C-D of the same figure.
On referring to the drawing it will be` seen that the under surface of the nozzle base plate u, is formed with the central recess b and end recesses c ordinarily communicating with the passage e leading to the swivel fitting f in which the tube g is mounted that forms a handle for the movement of the nozzle and is connected to the suction hose. In the present improved construction the passage e is a vertical slot formed in a central detachable block h slidably mounted in a rectangular slot k in the base plate a and formed with a lower horizontal flange m carrying the vertical rods n at each end that pass upwards through the hollow bosses o at each end of the base plate (1. and .are encircled by the springs p. The lower ends of the springs p bear against the circumferential ledges q in the base of the bosses o while their upper ends press against the caps 1' that flt into the upper ends of the bosses o the tension of the springs p being adjusted by the pins s passing freely through holes in the caps r and engaging threaded holes in the rods n.
By these means the under surface of the block h with the recesses t and u therein is normally maintained above the level of the under surface of the base plate a with its recesses b and c but by pressure applied through the handle g to the fitting f, that is swivelably attached to the upper surface of the block h by the barrel hinges v, the block I1. is lowered so that its under surface is in contact with the carpet and the suction effect is concentrated within the recesses t and u and this combined with the action of the brush mounted ina cut-away of the undersurface of the flange m of the block h, effectively removes any obstinate clinging matter. On relaxation of pressure on the block h it returns to its normal position by the action of the springs p.
A slot w cut through the forepart of the nozzle base plate a and communicating with the recess b admits a jet of air to the under surface of the plate which facilitates the movement of the nozzle over any kind of carpet and materially assists the cleansing of its surface. Moreover when the interior nozzle h is brought into operation it tends to clean the brush :n.i
It Willbe understood that variations in the structure may be made within the spirit and scope of the invention as defined in the appended claims.
I claim:
