Specification of Letters Patent.
Patented May 3,1921.
'i naatn filed much 11, 1920. Serial a... 365,101.
To allwhomz'tmag] concemz Be it known that I, GnoRcE QUA MAN, a citizen of the United States, residing atlo' ledo, in the county of Lucas and State of Ohio, have invented certain new and useful.
Improvements in Vacuum-Cleaner Attachments; and I do declare the followmg to be a full, clear, andexact' descr ption of the 1nvention, such as will enable others skilled m the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a par 'of this specification.
My invention relates to an attachment for electric vacuum-cleaners, whereby, by means these cleaners, as ordinarily constructed, may be utilized to take the place of the drlers commonly employedby women for dryingtheir wet hair after a shampoo.
In carrying out my invention, I avall myself of the presumed a vacuum-fan in an electric vacuum cleaner, which at 1ts dlscharge side is a blower, and of the presence of electric conductors capable of: furnlshing an electric current for heating the requisite air-currents.
To these ends, my invention consists of the devices, construction and arrangement of parts hereinafter described, and illustrated in the accompanying drawings in wh1ch Figure 1-, is a side-elevation of my device; Fig.2, a top-plan view of the same 1n central horizontal section, taken on line w-w Fig. 1; Fig. 3, an enlarged like view of a portion of the same, and Figs. 4 and 5, sideviews of the supporting diaphragms hereinafter referred to, detached.
Corresponding numerals represent like parts throughout the drawings.
In the drawings, 11s the discharge-plpe of the fan-chamber of an electric vacuum cleaner, of the usual or any preferred sort, the elements of which are so well understood as to require no further illustration or description here. 2 is an elbow section of pipe which, at one end, forms a slip-joint 3 with ges, as
the pipe 1, and at its other end en e tubua slip-joint 4, the smaller end of lar flaring funnel-shaped member 5.
Diametrically disposed in the chamber 51 the funnel-shaped piece 5 are two ' diaphragms 6 and 7 having therethrough numerous openings 8, of sufiicient extent to ermit the free passage of air-currents. ach
of the diaphragmsjhasacentral opening 9.
in which opemngs are supported the oppo-Y- site ends of a tube or barlO, of 'a suitable 'refr'actory insulating material, preferably, as in the g Around t is tube, are spirally woundheatresent lnstance, a porcelain tube.
ing strips or coils 11, of .wire of high electrical resistance. One endof the heating coil 11' is connected with inleading wire 12, the other end bein connected with the outleading wire 13. hese wires are connected with binding-posts 14 and 15, mounted on the part 5, which posts are adapted also for connection with wires 16 and 17, connected witha suitablesource of current, as, for instance, the inleading and outleading wires of the motor of the vacuum cleaner.
The operation of my device is as follows: The vacuum cleaner,or that portion of it which contains the 'fan,is placed on a table, and the usual dust-tube is replaced by the elbow 2 forming the joint 3, the interior of the part 5 being now in'communication with the blower side of the fan-chamber. The wires 16-17 being placed iii-circuit and the motor of the cleanerbeing in motion, the
.vertically, by means of the slip-joint 3.
Having described my invention, What I claim and desire to secure by Letters Patent let member of a vacuum cleaner.
2. In a device of the described character, a funnel-shaped member, two foraminous diaphragms in the chamber of said member,
a tube of non-conducting refractory material having its ends supported in said diaphragms,.an electric heating element coiled about said tube, an inleading wire and an outleading wire operatively connected with the terminals of the heating element, andmeans for detachably connecting the inlet driven vacuum cleaner as a hair drier, comsuch air-current, means for. connecting the inlet end of said tubular member with the discharge opening of a vacuum cleaner, and
a conductor for the heatingelementoperatively associated with the conductor for such vacuum cleaner. I
4. A hair drying attachment for an electric vacuum cleaner comprising a tubular memberadaptedto, discharge and direct an air-current, means for connecting the inlet end of said tubular member with the discharge opening of a vacuum cleaner, an electric heating element in said tubular member,
and electrical conductors common to said heating member and such vacuum cleaner. 5. In a device ofthe described character, a funnel-shaped tubular member, two foraminous dia hra sin the chamber of said.
member, an e ectric heating element carried tric circuit, an elbow-pipe connected at one end with the smaller end -of the funnelshaped member, the other end of the elbow-v pipe belng adapted for connection as a rotatable slip-joint with the discharge-pipe of an electric vacuum cleaner.
. In testimony whereof I 'aflix my signature 1n presence of two witnesses.
