EXHAUST 0R SUCTION NOZZLE.
' Specification of Letters Patent.
Patented Apr. 2e, 1910.
Application filed September 21, 19071. Serial No. 393,935
l'o all whom 'it may concern:
' Be it known that I, AMON T. N on, `a citizen of the United States, residing at Parnassus, in the county of Westmoreland and State of Pennsylvania, have invented cer-A tain flew and useful Improvementsin Exhaust' or Suction Nozzles, of which the following is a specification.
My invention relates to exhaust -or suction nozzles, vand moreparticularly to devices of this character of a type adapted for use in connection with pneumatic cleaning or renovating apparatus.
The primary object of my invention is to provide a device of this character which can be effectively used to remove dust from irregular surfaces, such as moldings, brica-brac; etc.,in a highly'efficent manner.
A further object of theinvention is to provide a suction nozzle rwhichcan be freely used on finely fin'ished walls, furniture, etc.,
without fear of injuring the same.
With the above and other objects in View, my lnventlon consists 1n the constructlon and arrangement hereinafter described, and
illustrated in the accompanving drawings, in whchi i v Figure 1 is' a pei'spectiveview of m improved nozzle; Fig. 2 is a central ongitudinal section thereof; and Fig. 3 is a central transverse section ofthe same. In pneumatic cleaning systems as now employed, it is the common practice to provide a power-driven'suction fan or' pump in connection with some suitable type of dust collector, and, from such apparatus,to extend a flexible hose, th end of which is fitted with any desirable; form of suction nozzle. By moving this nozzle about over fioors, wa 1s, or furniture,l 'the dust is drawn into the same, and carried, b means of the` flexible hose, to the dust col ector.
`Referring to the drawings in detail, my improved nozzle com rises a hollow tapering body portion 1, tted to a metallic cap .2, provided with a screw-threaded sleeve 3,
of this slot is arranged a row of tufts or bristles 6, thus forming afbrush, one of said rows being set into the lower ed e of each of said side members 4 and 5. ecured to the lower part of /the bod of the nozzle, and embracing said brush, 1s a fiexible wall Or curtain 7. prises a continuous band of'india-rubber, or other flexible, impervious material, secured to the bodyb means of tacks 8. It will be noted that t iis curtain closely hugs the body l, and the brush, and is of such width that its lower edge. lies substantially in the plane of the end of the bristles. AIt will thus be observed that when resting flat on a plane porous surface, such as a carpet, the curtain causes the air to be drawn 'in through the carpet, and therefore results in drawing the dust out of the same.
If used to clean u holster or. other ir,- regular' surfaces, suoli) as mo din s and the like, .the curtain 6 prevents air eak-ing in through the brush, Where it would be use- As shown, this curtain com less, and compels it to rush in close to or through the surface being cleaned. This is due to th'e fact that the curtain bein flexible, readily conforms tothe contour o the surface against which it rests, and effectively excludes the air.
, When used against a fiat, impervious surface,'s`ucl1 as a wall, the nozz e is'sliglitly tilted, thus. leaving. a narrowncrack alon one side, while 'owing to the flexibility o the curtain, the airl is practically excluded from all` other points. Too much stress cannot 'be laid upon this feature, as the efii- 'ciency -of these nozzles depends entirely upon preventing the entrance of. air from a points other than the immedlate point from which it is desired to remove the dust. It is obvious that brush nozzles if constructed with rigid walls, cannot accomplish this result, especially on irregular surfaces.
It will also be noted that there are no V Having thus described `my invention, what 110 l en d of the hollow body and disposed along body portion having provision along" its edge of the curtain 'lying in substantially the same plane, and a hollow sleeve project# same plane..r
I claim a's new and desire to protect by Let- I ters Patent is 1. A vsuction nozzle comprising a relatively long and narrow hollow body portion having any elongated slit inthe lower end thereof which leads into said hollow body, tufts ofbristles4 pojecting .from thelower opposite sides of said slit, a 'flexible impervlous curtain surrounding said 'tufts of bristles, the ends of the bristles and the 4lower ing from the said body portion."
2.` A suction nozzle vcomprising a hollow 3. A suction nozzle comprising a hollow body portion having a slit along the lower thereof, bristles adjacent said slit, and
die a eXible, impervious curtain surrounding said bristles, 'the ends 'of the bristles and the lower Vedge of lsaid curtain lying substantially inthe same plane.
4. A suction nozzle0 comprising a hollow body portion of tapering form, having a` narrow slit along its lower edge, a row of tufts of bristles disposed along each side of said slit, and a flexible, impervious curtain secured to said body portion, and embracfing said bristles, the endsy of said bristles lying in substantially the same plane as the lower-edgeof said curtain.
Y In testimony whereof* I have yaiixed my vsignature in presence of two witnesses.
