PPARATUS FOR SIMULATING A SNGWFALL J osef Hermann, Bellaire, N. Y. Application July 15, 1949, Serial No. 104.847
7 Claims. 1
This invention relates to an apparatus for simulating a snow fall and particularly to an apparatus which is designed for use in display windows.
The principal object of my invention is to provide a device that will cause the permanent fall of artificial snow fiakes along a relatively wide area in a display window which is decorated as a winter scene.
It is another object of my invention to provide a device which collects the fallen artificial snow flakes and conveys the same to an upper position from which it falls down again over a relatively wide area. 7
It is still another object of my invention to provide a device which carries, artificial snow flakes to an upper position and which is equipped with'means for releasing; the snow flakes at predetermined positions.
It is yet another object of my invention to provide a device with means for releasing are tificial snow flakes simultaneously at a plurality of predetermined positions.
With these and other objects in view, which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings in which.
Figure l is a front elevational view of a display window with a winter scene, showing a snow fall;
Fig. 2 is aside view of the device according to the present invention partly in section;
Fig. 3 is a front elevation of; the device, part of which is broken away for the'purpose of better demonstration;
Fig. 4 is a front elevation of a part of the device, a portion of which is broken away for the purpose of better demonstration;
Fig. 5 is a rear elevation of the device;
Fig. 6 is a fragmentary. view of a variation of the drive;
Fig. 7 is a schematic elevation of another embodiment ofthe device; and
Fig. 81s a detail of the device shown in Fig. 7 on a larger scale.
Referring now to the drawings and particularly to-Figs. 1 to 6, the present invention achieves the above stated objects by providing preferably endless conveyor means which are equipped with a plurality of blades or fins disposed inv differentpredetermined angles to the conveyor means in such manner that the blades carry artificial snow flakes of plastic, paper or any other suitable material to an upper zone of the device, to be released simultaneously over a wide area which corresponds about with the width of the device. If the device is thus positioned in a display window of a width about equal the width of the device, and the entire window is decorated as a winter scenery, the continuous fall of snow over the entire scenery may be simulated;
The embodiment shown in Figs. 2 to. 6' comprises a support I the upper extension 2 of which carries a horizontally disposed axle 3.
A wheel i is mounted preferably by means, of a ball bearing 5 for rotation upon the axle 3. The wheel 4 comprises a disk 8 which carries at its periphery a plurality of bars i in forward: direction and the front ends of the bars! sup! port a ring 8 which at least partly serves the purpose of receiving one end of a plurality of blades 9 disposed around the entire wheel. 4, while the other end of the said blades 5 is secured in, the disk 6.
It is an essential feature of the present invention to dispose. each of the blades 9 at a predetermined angle in such manner that the snow flakes, received by the blades 9 when in their lower position on the wheel 4, are carried to the upper position on the latter upon turn-' ing of the wheel 4, yet the snow flakes are released at a point on the wheel 4 which is determined by the angle at which the blade 9 is disposed in the wheel. Thus by arranging the blades 9 at different angles, as clearly shown in Figs. 3 and 4, some of the blades 9 release the snow flakes before reaching the highest point on the wheel l, while others will be carried beyond the highest point. In this way snow fall may be simulated over a great width of the device, which will be slightly less than the diameter of the wheel.
In order to provide the possibility of adjusting each one of the blades 9, preferably prope means for easy turning of the blades along its longitudinal axis and for securing the same in the desired position are devised. By example, as shown in Fig. 2, each blade 9 is equipped with pins ii! at their ends which pins It are disposed along the longitudinal axis of the blades and enter corresponding openings H and I2, in the disk 6 and in the ring 8', respectively. They retain their positions by friction between the pins It and the openin s II and ll, though other conventional securing means may be provided. The front of the wheel 4 is covered with a transparent sheet I3 of glass, plastic material or the like, though it is also possible in some cases to use a sheet of suitable color. The pe riphery of the wheel 4 is likewise covered with a sheet l4 of the same material as the sheet [3, which sheet l4 serves the purpose of providing light effects by means of light beams (not shown) through the slots formed between each pair of adjacent blades 9.
Behind and spaced apart from the disk 6 a toothed gear I is rotatably mounted on the axle 3 by means of a second ball bearing l6 which gear [5 meshes another gear I! which is driven by an electric motor over a reducing gear (not shown) or any other conventional drive. A plurality of bars 18, Fig. 5 shows by example six bars, connect the gear l5 with the periphery of the disk 6, in order to secure a smooth turning of the wheel 4 on the axle 3 without any vibration. Instead of driving the wheel 4 by means of the gear l5, the periphery of the disk 4 may be equipped with a circular rack l5 (Fig. 6) and the gear l'l meshes in this variation the said rack l5.
Since it is desirable to cover up all rotating parts from a viewer of the display window, means are disposed in front of the rotating disk 6, which means are stationary, and enhance the illusion of falling snow on a winter scenery. In order to. achieve this end the axle 3 extends into the wheel 4 and the front end of the axle 3 supports a stationary disk IS the front of which carries the picture of a winter scenery (see Fig. l). A plurality of bars 20 extend from the periphery of the disk H3 in forward direction which support a number, for example four, ring members 2| which are disposed like wings on a stage to cover up completely the rotating blades 9 from a viewer of the display window while freely permitting the fall of the artificial snow between each pair of adjacent ring members 2|. To serve the same purpose ring sector like parts 22 may be additionally secured to the lower portions of the most forward ring member 2| which parts 22 are of somewhat greater width than the ring members 2| and each of the parts extends over about at least 45".
The thus described device operates in the following manner:
. Before closing the front of the wheel 4 the required quantity of artificial snow flakes is inserted into the wheel 4, which snow flakes will accumulate on the blades 9 which are at the lower portion of the wheel 4. Upon starting rotation of the wheel 4 by means of an electric motor or any other drive, the snow flakes will be carried to the upper portion of the wheel 4 and depending upon the angle at which each one of the blades 9 has been set, the snow flakes will be released at different positions of the wheel simultaneously and simulate a snow fall practically over the entire width of the wheel in front of the winter scenery provided on the stationary disk [9. The; fallen snow will accumulate again on the blades which happen to be at the bottom of the wheel and by continuous rotation of the wheel this process will be repeated and thereby provide a continuous snow fall.
While it is merely essential to provide a plurality of blades disposed at diiferent predetermined angles which are carried from a lower zone, where they receive the fallen snow, to a higher zone, where they release the snow at different point depending upon the angle of each blade, the embodiment, as described above, in form of a wheel, is preferable in view of its simple and economic construction and its easy operation.
The present invention is, however, by no means limited to a wheel as a carrier means of the blades 9 from a lower to a higher zone where they are released.
Any convenient carrier means may be provided and one second embodiment is shown in Figs. 7 and 8 in form of a conveyor belt 23. As shown in the drawing, preferably five rollers 24 are provided, which rollers carry an endless belt 23. The inner face of the belt 23 carries a plurality of blades 9 which are disposed at predetermined angles relative to the inner face of the belt in order to release the lifted snow flakes at difierent points during the travel of the belt. Preferably the upper wheel is adjustable to regulate the tension of the belt 23. The rollers 24 are designed in such manner .that they freely permit of movement of the blades 9 through the rollers 24. One of the rollers 24 carries a gear 25 which meshes a pinion 26. The latter is connected with an electric motor over a gear reducer (not shown) or with any other driving source. Any convenient means as a frame 21 may be provided to cover up the belt convey-or from a viewer of the display window.
It is to be understood that while in the drawings a wheel of circular shape and a conveyor belt on five rollers have been disclosed, this showing is by example only and the wheelmay be of hexagonal shape and the conveyor belt may be mounted on only three or more rollers.
While I have disclosed two different embodiments of the present invention, it is to be understood that these embodiments are given by example only and not in a limiting sense, the scope of the invention being determined by the objects and the claims.
