ARTHUR W. KINDEL, OF DENVER, COLORADO.
NOZZLE FOR PNEUMATIC CLEANING APPARATUS.
Specification of Letters Patent.
Patented June 16, 1908.
Application filed September 28, 1907. Serial No. 395,033.
To all whom it may concern:
Be it known that I, ARTHUR W. KINDEL, a citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Nozzles for Pneumatic Cleaning Apparatus, of which the following is a specification.
This invention relates to new and useful improvements in nozzles employed in conjunction with pneumatic cleaning apparatus and its object is to provide a device of the class named which, when brought in contact with the carpet or other object to be cleaned, will, by reason of its peculiar construction, cause separation of the nap or ric and permit a constant in ux of air and which, in consequence, is instrumental in effectively, thorou hly and speedily-removing the dust and irt contained in the substance to which it is applied. I attain this object by the mechanism illustrated in the accompanying drawing in the various views of which like parts are similarly designated and in which Figure 1-represents an underneath view of the improved nozzle, Fig. 2-'a vertical section taken along a line 44, Fig. 3. Fig. 3a transverse section taken through the center of the device, Fig. 4a cross sectional view of the mouth of the nozzle in position on a carpet, drawn to an exaggerated scale, and Fig. 5a perspective view of the improvednozzle in operative position.
Referring'to the drawings, let the reference character 5 designate the nozzle or hollow head, composed of the upwardly convergent end walls 7 and the curved side walls 6, which as they approach the lower extremity of the .device, are drawn together to form a the mouth 8 of which 0 ens into the working face of the nozzle and t rough which the impregnated air is introduced into the suction chamber 9.
A socket or union 10 opening in the chamber 9 at the uppermost portion of the head is designed to ile of the fabsecure the extremity of a tubular handle 11 through which the dust and dirt-laden air is conducted to a conveniently located separator which for obvious reasons is not shown in the drawings.
The mouth 8 of the nozzle, which is of uniform width, is bounded by lips 12 which curve out and u wardly from the edges of the mouth, and t e walls of the narrow neck 13 which connects the orifice 8 with the suction chamber, are connected by means of a corrugated strip 14 the lower edge of which extends in a plane with the adjoining edges of the mouth. The strip 14 is composed of a narrow stri of metal and may be secured to the walls 0 the neck 13 by solder, or other suitable fastening means.
When the mouth of the nozzle is applied to a carpeted floor, as illustrated in Fig. 4 of the drawings in which the reference numeral 15 designates the carpet, the lower edge of the corrugated strip and the adjoining edges '16 of the mouth 8 engage the nap or pile thereof while the lips 12 curve upwardly free from contact therewith. The corrugated strip 14 engaging the nap of the fabric, disentangles and separates the hairs or fibers of which it is composed and agitates and exposes the dust and dirt and thus facilitates its removal. The corrugations of which the strip 14 is com posed, prevent the nap of the carpet from entering and consequently obstructing or choking the mouth of the nozzle, while the upturned lips 12, being free from contact with the surface of the carpet insure a free passage of the surrounding air into the suction chamber, when b means of suitable apparatus connected with the handle 11, a vacuum is produced therein. It will thus be observed that by the use of my improved device, all the dirt and dust contained in a car et or other fabric, may effectively be dis odged and by reason of the continuous, unobstructed flow of air, be speedily and comgletely drawn into the suction chamber, to I e conveyed to the therewith communicating separator.
wardly from its edges, and a corrugated strip connecting the walls of the said'iinlet, in a plane with the said edges.
Having thus described my'invention, what I claim is:
1. A nozzle for a neumatic cleaning device com rising'a hol owhead having an elon- In testimony whereof I have affixed my 5 gated in et,-and a corrugated stri connectsignaturein presence of two Witnesses.
ing the walls thereof, in a plane wit its lower a ARTHUR W ,KINDEL edges. 2. A nozzle fora pneumatic cleaning de- Witnesses: vice comprising a hollow head having anl K. M. STUMP 10 elongated inlet and lips ranging up andout- G. J. ROLLANDET.
