To all whom it may concern: l
Be it known that we; HERBERT H. Pom.
' and Ror- D. NEILL, citizens of the United- States, residing at Minneapolis, in the county of Hennepm and State of Minnesota,
have invented certain new and useful'Imrovelnents in Frost-Prevention Devices for gvindows, of which the following 1s a speclficationr Our invention relates to frost prevention devices for windows. An object of the invention is .to provide a device which may be readily applied to windows to prevent' the formation of frost thereon or upon a portion thereof in cold weather. Our device is particularly applicable to wlndshlelds and other windows of motor vehicles, but may be applied to all windows where frost is liableto form and obscure the view, such "as display windows, We accomplish the objects of our invention by providing a device consisting of I transparent material which is securedto'. the window in airtight spaced relation thereto so that a dead-air space or pocket'is produced. I
The full objects and advantages of'our invention will ap ear in connection with the detailed description-thereof and thenovel features of our inventive idea .w1ll be par-f ticularly pointedout in the claims. i
' In the accompanying drawings which il lustrate a practical embodiment of our invention, I 3
Fig. 1 is an elevational view with the cen tral portionbroken away showing our iiivention a plied to the windshield of a-mo. tor vehiclii. Fig 2 isja viewin horizontal section. Fig. 3 is a view in horizontal section showing a slight modification. Fig; 4
is a view 'in. horizontal section showing a In the} particular embodimentshown in appliedto a windshield IQ-which is supported'b posts 12' and 14 i-nthe' usual manner. "T 'e. device-broadly considered consists of apiece oftransparent material which 'is secured! tothe lass win:
to and with itsbody portion' -spacedthere from.- We. have found celluloid to terial which is shown a; piece-of sheeteel u oidv 16 whose edges K flanges 18 which arebent out'wardiy at right angles to f form attaching {flanges 20 lying much easier and safer, -'d1splay window's,
readily observe t be a ma; particularly adapted forv urposes have w ndow for bent at rlght angles to.- form parallel to the body portion. These at- I tac the transparent sheet is of such size as to require additional support, spacing means may be placed between the sheet and the window. Fi 16" provided with avridge 24 adapted to g. 3 shows a transparent sheet rest upon the window. Fig. 4 shows a transparent sheet 16" provided with two ribs 26 and 28 adapted to rest upon the window.
The operation and advantages of our inventlon will now be obvious. In cold weather the device can be readily attached to windows such as ularl liable to become coated withfrost *whic obscures the vision therethrough. On
that the transparent account of the fact material is secured to the'windowin spaced substantlally airtight relation a dead-air space is produced which prevents the. formation of frost over the rotected area. In the case of motor vehic and in the case of persons on the outside can e objects on display on V Windshields and other. windows of motor vehicles which are partices driving is made the inside. Celluloid is considered a particularly desirable material Sll108 "1t can be-readily shaped between ed dies to produce the flanges and-ribs, and
furthermore this material isflexible and-not easil cracked or. broken.
