Application med November 29, 19,12. serial No. 734,012.
To all whom it may, concern.;
Be it known that I, CARLO. LINDSTROM,
a citizen of the UnitedStates, and aresident.
of the city tof Chicago, inthe county of. Cook and State of Illinois, havehinvented certain new and, useful Improvements in Disinfecting or Perfuming Apparatus; and I do hereby declare that the following is a full, clear, and exact, description of the same, reference 'being had to the accompanying drawings, and to the numbers of reference marked thereon, which formfa part of this specification.
-Dlsinfection of rooms has been Aaccomplished by placingcloths saturatedwith thel disinfectant in the room Vand sometimes sus ,f
Where disinfection is accomp ished in this manner, the atmosphere surrounding the impregnated or saturated cloth.' or sponge becomes more or less pendingV the same.
charged with the disinfectant; if ,the disin.
fectantvbe volatile, while where the atmosphere in parts of 4the room more distant may contain a much smaller percentage of the disinfecting material. Particularly is this true when rooms are sealed for dlsinfecting, inasmuch asl the movement of the ldisinfecting. apparatus whereby a definite charge of the disinfecting materialV may be delivered to the atmosphere and intimately mixed and distributed through the atmosphere so that all parts of the room receive equal treatment.
It is an object of the invention to afford a device whereby the circulation'is ,maintained in the room after the sealing of the same for disinfection and whereby the charge of disinfectingmaterial is delivered to the air at the point of greatest circulation to permit distribution throughout the entire room or space tobe treated.
It is also an object of thev inventionto ali'ord mechanism whereby a predetermined amount of the disinfecting fluid may be delivered, the, amount, of course, depending upon the, size of the room or space to be treated.
The .invention also. has forits object a mechanism whereby a constant treatment of the air ma beatforded for remedial or curative efiict or to perfume the air, as preferred. i y
The invention (in a preferred form) is illustrated in the drawings, landhereinafter more fully pointed out and defined inthe appended claim.-
vIn thedrawingsrFigure 1 ,is a side elc- Vation of a devioeembodying my invention. Fig- 2is a front elevation thereof. Fig. 3 is an enlarged vertical section illustrating the controllm'g and regulating means for delivery .ofthe fluid from its container. Fig.
4 1s a Sectionon line 4 4 of Eig. 3. Fig. 5 is an enlarged, vertical section taken through the wick-holder andv supporting clamp. Fig. 6 is a fragmentary IView in side elevation of the wickholder illustratedin Figs. 2, 3, and
4, and illustrating a slightly modified clamp.
As shown in the drawings: 1, indicates an ordinary electric or other power driven fan, rovided as usual,\with any suitable guard which may be constructed of wire, indicated by 2, in Fig. 1, in which a vertical wire is shown connected to the frame of the fan' and extending down over the front thereof. ,r p
The guard illustrated .in Fig. 2, comprises, as shown, a wire fr ame consisting of a ring 3, of wire. supported outwardly in front of the fan and extending around the same, and
connected transversely or across the v:liront of the fan b 4. The container for the dy other liquid, is supported on the fan guard as .hereinafter described, andA comprises a cup 5, to contain the liquid, having a base 6, provided with a small central passage opening therethrough, inL which extends a ho-llowmember u'having its lower end tapered at 6b, said member and the surrounding collar 6 of base 6 having registering apertures Gd to, permit the passage therethrough of thehliquid. Said tapered lower end 6b affords a seat, vcomprising what may diametrically radial wires isinfectant o1.'
. for disinfecting purposes, for e be termed essentially a needle valve. The stem 7 of said valve extends through the cap 8, of the container and through an ad justing nut 9, in a familiar manner, and is provided at its upper end with a lever 10, whereby said stem 7, of the needle valve may be raised to permit the slow discharge ofthe contents of the container drop by drop, and for this purpose a sight feed chamber 11, is provided below the needle valve, in which the drops of liquid can be seen to fall from the valve.
Threaded into the lower end of the sight feed chamber is a wick tube 12, and also disposed on` said tube below the collar 19 afforded by the sight feed chamber, is a washer 13, between which and the bottom collar on the sight feed chamber the guard wire 3,' of the fan may be engaged, as shown in Figs. 1, 3, and k5, to rigidly support the device in operative position in front of the fan. Loosely secured Within the wick tube 12, is awick 1.1, adapted to become saturated by the liquid discharged through the needle valve from the container.
Should it be desired to support the device upon a vertical member of the fa-n guard, obliquely directed apertures are provided in the bottom flange or collar 19, of the sight feed chamber 11, as shown in Fig. 6, and an oppositely inclined aperture in the washer 15, which is mounted on said wick tube. A nut 16, is provided on said tube, as shown in Fig. 6, so that the-wire having been eX- tended through said apertures, as indicated in Fig. 6, the washer tilting upwardly at one edge to permit the same being passed therethrough, the nut may be set up, thus jam:
ming the washer upwardly against the base `flange or collar 11, on the sight feed cham-i ber and cramping said wire between the same, because of the Obliquity of said resi'iectiye apertures.
The operation 1s as follows: When used mple, when it is desired to completely an thoroughly disinfect a room, the device is secured on the fan guard, as before described, and is filled with the required disinfecting liquid, usually of a more or less volatile nature,land should the charge required for complete disinfection be more than the capacity of ythe container 5, a larger container 17, or in fact a tank, can or receptacle of any kind containing the required amount of the liquid for the complete disinfection may be supported in any convenient way above the container 5, and connected to communicate with sald container 5, through a tube 18, which, communicatingin said tank 17 discharges into the container through the filling aperture, the plug 20, for the filling aperture having been removed, of course, and the end of the pipe 18, being threaded thereinto. The fan is now started in motion, and if desired, the room may be sealed in the usual manner. The draft of air`oceasioned by the fan is directed in part upon the wick tube, and is driven through the wick carrying outwardly the vapor of the disinfectant contained in the wick, and the rapid flow of air occansioned by the fan greatly` facilitates the vaporization of such disinfectant. The needle valve, of course, is adjusted to deliver the liquid to the wick as fast as the same may be taken therefrom into the atmosphere and the action is very rapid owing to the complete circulation of the atmosphere of the room because of the action of said fan. The amount of the disinfectant required for the room may be easily determined from the measurements of the room itself, and the required quantity, of course, is placed in the container 17, if the container 5, is not of suiiicient size. When all the disinfectant has been taken up by the air of the room, the desired point of saturation will be reached, and the operation therefore completed.
Of course, when used for remedial treatment, as for example, charging the atmosphere of a room with a remedial agent to be inhaled, the needle valve is adjusted to give the required rate of discharge froln the container to maintain the required per centage of the remedial agent in the atmosphere. lVith such use, of course, the room is not sealed and a somewhat larger portion of the remedial agent or medicament is required for that purpose. When so used, if desired, the fan may be laced at a window opening Vto draw fresh air into the room to medicate the same to the desired extent and to deliver the same into the apartment. In the same manner a perfume may be used.
Of course, the wick tube may assume any desired form, for example, it may be a simple metallic tube perforated on opposite sides to permit the air from the fan to be driven therethrough, as shown in Figs. 2, 3, 4, and 6, or if preferred, the wick tube may be constructed wholly or in part of wire gauze to properly support the wick by permitting a free iow of air therethrough from all directions.
Of course, the wick tube may be of any desired form in cross section, and if preferred, may be of greater diameter or `width in a plane parallel with the fan than in a plane at a right angle therewith.
Of course, numerous details of the construction may be varied. I have shown but a preferred form of my invention. I therefore do not pur ose limiting myself otherwise than necessitated by the prior art.
