E. T. NORBECK FROST SHIELD Filed March 9, 1928 EMU T. Nor bck Patented Apr. 8, 1930 UNITED STATES A EMIL NORBECK, OF MINNEAPOLIS, MINNESOTA FROST SHIELD Application filed March 9,

My invention relates to frost shields and has for its object to provide a. transparent member with a frame portion integrally connected to said member.

Another object of the invention resides in forming said frame with an offset portion having a plane surface substantially parallel to the body of said transparent member andwith an outwardly flaring portion connected to said oflset portion and in permanently attaching'to said outwardly flaring portion a. flexible contact strip adapted I to yieldably and freely contact with the surface on which the frost shield is to be applied.

Another object of the invention resides in depressing the corners of the transparent member to the level of the offset planiform portion and of-attaching suction cups to the corners of said member. said suction cups be ing disposed within the outwardly flaring portion of said frame and having the surface thereof disposed substantially in continuity withthe edge of said outwardly flaring portion.

attaching said contact strip jointly to said outwardly flaring portion and to said suction cups, the edge of said contact strip coinciding with the edge of said suction cups and extending outwardly beyond the edge of said contact strip.

relatively light construction which will not readily shake loose when applied'to the wind shield and which will form a continuous contact through its extent so as to provide a perfect dead air space and prevent the frosting of the Wind shield when the temperature becomes suflicientlylowered. It is further desirable to construct the frostshield in such a manner that the same is notr'eadilybroken and in the event that the device isroughly handled so that the same will not become permanently injured. 'My invention provides a structure whereby all of these benefits are secured as will become apparent from the following description: p

The invention proper, which is best shown in Figs. land 2, comprises a sheet of celluloid 10 which isarranged with a body portion 11 of proper size and shape and which forms the window through which vision is had. In the instantcase I have illustrated the por-. tion 11 as being substantially rectangular in form though it can readily be comprehended thatany size or shape'of'the device may be employed. The frame of the device which is indicated in its entirety at 19 is" formed by subjecting the celluloid to pressure in suitable dies under heat. Along the marginal portion of the sheet 10 the same is pressed to provide an offset planiform strip or portion j s 12 which is parallel to the body portion 11 The full objects and advantagesof my invention will appear in the detailed descripand extends completely around the same. In additionthe extreme marginal portion of the sheet lOis pressed to form an outwardly flaring portion 14 which extends away from the body portion' 11 and forms a space bej tween the extreme edge 15 of the device of the body portion proper. When applied to a wind shieldor other window on which the device is to be used the body portion 11' serves'as a storm window orauxiliary transparent member through which clear vision may be, had while the planiform portion 12 and the outwardly flaring portion 14 form a frame structure integrally connected with the planiform portion 11 and completely surrounding-the same which I previously stated is designated in its entirety at 19.

At the four corners'of the body portion 11 indicated at 16 the body of said frost shield cupsso that the same maybedisposed .Witl1- in the frame structure 19. previously'referred;

It will be noted that the openings 18 are so disposed and the corners of the outwardly flaring portion 19 fsheet -10-is'soconst-ruct ed that the same contacts with thesurfaceofl. the suction cups 17, causing the stirfacebfsaid suction cups at their contacting-(portions with the members 14;, to lie in substani tiall continuity; ttherewith.
