749,519. Moving signs. TUCK & SONS, Ltd., R. May 31, 1954 [May 29, 1953], No. 15065/53. Class 3'(1) [Also in Group XV] A pictorial device for depicting snow scenes and the like comprises a container of shallow depth between opposite walls 1, 2 one at least of which is transparent, a filling of liquid in the container, the liquid being clear but accompanied in the container by a mass of small particles 12 of material insoluble and heavier than the liquid, and a picture or other representation applied to one of such walls in such a manner as to be visible through the opposite wall and the liquid. The arrangement is such that when the container is inverted the small particles 12 descend as a cloud in the liquid. As shown the container is defined by the walls 1, 2 and a hollow rectangular framework 3, the upper part of which is provided with holes 10, 11 for filling the container. The container is divided into two parts 6, 7 by ribs 4, 5 on the walls 1, 2 which constitute a baffle device for the particles 12 so as to control their passage from one compartment to another. The container is mounted within a cover 13 in which are formed rectangular apertures 14, 15 adjacent the walls 2, 1 and opposite the compartments 6, 7 respectively. Pictures 16, 17 are secured to the cover 13 to be viewed through the apertures 14, 15 respectively. The device may be incorporated in greetings cards and an outer cover may be hinged to the device so that is opens like the front cover of a book. Alternatively the device may be made up as an ordinary picture which may be framed, the device then having only a single compartment with the baffle device at the top. One of the walls 1, 2 may be moulded integrally with the framework 3 or both walls may be moulded integrally with part of the framework 3.
