yaw- 561 42 ATTOR N S United States Patent Office 3,053,460 ICE REMQVING APPARATUS Charles E. Rudy, St. Clair Shores, Mich, assignor to Continental Aviation and Engineering Corporation, Detroit, Mich, a corporation of Virginia Filed Apr. 13, 1959, Ser. No. 806,149 Claims. (Cl. 239-407) My invention relates to snow and ice removal apparatus and more particularly to a nozzle structure adapted for connection with a source of heated compressed air and comprising assembly parts adaptable for various combinations.
As presently conceived, an object of the apparatus is to economically remove snow and ice from aircraft and other surfaces by utilizing the kinetic and thermal energy of compressed air, such as is furnished by high capacity mobile turbin compressors, in as efiicient a manner as possible. In situations where a heavy blanket of snow has not frozen to the surface, the high velocity air can readily remove the snow. When surfaces are coated with frozen snow and/ or ice, the high temperature of the air is used to melt a small area of the ice to expose the surface, after which de-icing proceeds rapidly because the heat applied to this area extends by conduction to adjacent areas. As new areas of ice are slightly loosened, they will be removed by the force of the high velocity air.
The present nozzle also includes a means for applying glycol or other ice inhibiting agent on urfaces from which all the snow and/ or ice is removed from a particular area. This provision is particularly useful for inhibiting ice formation on aircraft surfaces prior to take-off.
For a more complete understanding of the invention. reference may be had to the accompanying drawings illustrating preferred embodiments of the invention in which like reference characters refer to the parts throughout the several views and in which FIG. 1 is a top view of one nozzle assembly embodying the present invention.
FIG. 2 is a fragmentary elevational view of another modification of the invention.
FIG. 3 is a cross-sectional view taken substantially on the line 33 of FIG. 2.
FIG. 4 is a cross-sectional view taken substantially on the line 4-4 of FIG. 1.
FIG. 5 is a side elevational view of the nozzle portion of the assembly as seen substantially on the line 55 of FIG. 1.
FIG. 6 is a cross-sectional view of the nozzle structure taken substantially on the line 66 of FIG. 5, and illustrating a modified handle attachment in lieu of the handle assembly of FIG. 1.
FIG. 7 is a nozzle end elevational view as seen substantially from the line 7-7 of FIG. 6.
FIG. 8 is an illustration of the modification of the assembly of FIG. 1 as used by two operators, and
FIG. 9 is an illustration of the modification of th assembly of FIG. 2 as used by one operator on a mechanical boom.
Referring to the modification of FIGS. 1, 4, 5 and 8, the nozzle assembly 10 is illustrated as comprising preferably a tube portion 11 and a nozzle portion 12, the tube portion having annular flanges 13 at the ends. The nozzle portion 12 has a flange 14 adapted to abut one end flange 13 of the tube 11 and to be swivelingly secured thereto by any means such as a clamp 15 of conventional construction. The nozzle portion 12 tapers to an elongated flattened end 16. The other flange 13 of the tube 11 is adapted for connection with an air supply hose 17 as indicated in FIG. 8, the hose delivering heated compressed air from any suitable supply means (not shown).
In the modifications of FIGS. 1 and 2, the axially extending handle 21 can be provided with a valve assembly 30 of any preferred conventional type connected by a con, duit 31 with any suitable source of ice inhibiting agent (not shown) and by a conduit 32 with a nozzle assembly 33 mounted on the nozzle portion 12. The valve 30 can be selectively operated by means of a manual button 34 to provide injection of ice inhibiting agent into the air flowing through the nozzle portion 12.
In handling by one operator when a relatively lesser air flow would be sufficient, the tube 11 can be eliminated, the air supply hose being connected directly to the nozzle portion 12. In this event, as illustrated in FIG. 6, the nozzle portion 12 is provided with handles 40 and 41, the handle 41 preferably having a mounting 42 which carries a valve 43 similar in construction to the valve 30 shown in FIGS. 1 and 2. A conduit 44 preferably extends through the handle 41 as shown and connects the valve 43 with the source of ice inhibiting agent (not shown), and a conduit 45 connects the valve 43' with the nozzle assembly 53.
FIGS. 5, 6 and 7 illustrate the preferred construction of the nozzle portion 12 as having a nozzle plate 46 pro vided with a plurality of aligned spaced orifices 47 each having a rounded converging inlet side 48 for effecting a high velocity laterally elongated flow of air. A plurality of spaced diverging vanes 49 are disposed within the portion 11 for the purpose of providing a more uniform air flow over the length of the nozzle plate 46.
The nozzle plate 46 is held in a slot 50 which extends around the inner periphery of the elongated outlet 16, one end being closed by a cap 51 secured by any means such as screws 52. Thus the plate 46 may be readily removed for cleaning the interior of the nozzle portion 12. The ice inhibiting nozzle assembly 33 has a tube element 53 which extends into the air flowing through the nozzle portion 12 substantially as shown, the ice inhibiting agent, preferably glycol or a similar liquid, being selectively injected into the air for discharge from the nozzle orifices 47 to apply it to the surface being de-iced.
