Y., assignor to Multi Vue Sign 00., Inc., a corporation of New York Application October 19, 1937, Serial No. 169,762
This invention relates to a combination mirror and clock which may be used for advertising or other purposes. I
An object of the invention is to produce a device of the character described having a front mirror which may be used as a mirror per se by persons standing in front thereof, said mirror having combined therewith a clock the face of which when illuminated appears to view in place of the aforesaid mirror.
Another object is to produce a device of the character described wherein thefront mirror is translucent and one or both mirrors are movable whereby certain moving effects of indicia located within the device or indicia projected thereon, are obtained.
A further object is to produce a device of the character described wherein the hands of a clock are located in front of the mirrors therein while the clock face numerals are located (either with or without accompanying indicia such as advertising data or the like) on one of the mirrors or the indicia is projected thereon.
Other objects of the invention will be appascribed herein a device that may be used for ad- 7 vertising purposes comprising a casing having its front closed by a translucent mirror having a second mirror which need not be translucent in the rear thereof. Before the first or outer mirror are positioned the hands of the clock, the numerals for the clock face being placed on the second or rear mirror, or these numerals may be projected on to the device or reflected thereby in a manner hereinafter described.
With the device illuminated by ordinary light from the front, such for example as when the device is located in a store window and illuminated by ordinary daylight, the front of the device would present a smooth, unbroken mirrorlike surface except for the clock hands. Then by illuminating the rear mirror the outer m rror being translucent apparently disappears from view 55 and the numerals of the clock dial appear and rent from a perusal of the following specification because the two mirrors are spaced apart, repetitive reflections occur so that apparently these numerals go marching off into infinity in a manner well known in connection with reflecting signs of this character.
If one or both of the mirrors are moved, then the repetitive reflective images also move and a large number and variety of combinations of one or both moving mirrors can be effected to .produce various attractive effects. Some of these constructions are given in the copending appli- Cations, Serial Nos. 152,698, 152,699 and 152,700, all filed July 9, 1937.
It will also be understood that sign indicia may be placed on any one of the surfaces of either mirror. When placed on the mirror surface, the indicia is usually placed on the rear surface of the rear mirror, the opaque silver coating thereon being removed and the indicia placed on the clear glass using translucent colors. If the silvering is removed from the rear of the rear mirror and the indicia is painted in translucent colors on the front of the rear mirror and the sign is illuminated from the back, the letters apparently swing out surrounded by a halo or radiation of light due to the passage of light through the glass of the rear mirror, which light finds its way around the indicia. It will be understood it is immaterial in so far as the carrying out of this invention is concerned, as to where the indicia is placed and in this connection reference is had to the aforesaid application, Serial No. 152,698, in which the device proper does not contain any indicia at all or may contain part of the indicia and the image of indicia, such for example as a bottle, a package of cigarettes or other merchandise, is caused to fall on the sign to cause a primary image thereon by putting the merchandise in front of the device and strongly illumimating the merchandise, a reflected image of which is produced in the device, the mirrors therein cooperating to produce a plurality of images, which images may be caused to move by moving the mirrors in the device.
Another method of applying the indicia to the device is to direct a beam of light on to the device from a stereopticon or the like in which is a slide bearing the indicia. When the light beam strikes the device, the mirrors pick up the indicia projected thereon and operate as heretofore described. I
It will be seen from the foregoing that it is immaterial where the indicia is placed on the mirrors or projected or reflected thereon. For portable devices it is preferable to put the indicia on the back mirrdr and illuminate the same from means such as electric lamps contained in the casing of the device.
Referring now to the drawing in which is illustrated a device of the character described com prising a combination sign and clock:
Figure l. is a plan view, partly in section, of a device in which both of the mirrors are movable;
Figure 2 is a plan view, partly in section, of a device in which both of the mirrors are fixed;
Figure 3 is a front elevation of the sign shown in Figure 1, as seen with rear illumination; and
Figure 4 is a sectional plan view on the line 4-4 of Figure 3 showing the attachment of the clock hands to their driving shafts.
Referring to Figure 1 which is typical of any type of construction in which one or both of the mirrors are movable, the numeral 10 denotes a front casing in which is supported a plain glass front H which front, however, may in some instances be dispensed with. The casing I is provided with a door 12 on its side or in its top to permit removal of the mirrors which may be supported in a suitable framework, as more fully described in copending application Serial No. 169,761, filed October 19, 1937.
The outer mirror I3 and rear mirror It! are mounted to oscillate or swing about the vertical axis IS, the front mirror l3 being translucent and the rear. mirror l4 being opaque except when it carries indicia, in which case the silvering is removed from the glass and the indicia placed thereon using translucent colors.
The mirrors l3 and M are apertured at their center, as more clearly shown in'Figure 4 to permit the mechanism for driving the clock hands to pass therethrough. This mechanism may be of any suitable form, may comprise the usual hour and minute hand shafts generally denoted in Figures 1 and 2 by the numeral i6, which shafts are connected through any suitable gearing to shafts I! which are driven by a clock mechanism I8.
The clock mechanism 18 is disposed to one side of the mirrors so as to be out of the way in the event that the mirrors are illuminated from the rear, as hereinafter referred to, and the shafts I1 and the associated parts I S are also made as small as possible so as not to cause any shadows in the event of rear illumination.
If desired, the mechanism 18 may comprise any suitable form of spring or electric motor. If the latter is used, it may be any of the known types of such motors which commonly have an armature shaft which, through appropriate gearing drives the shafts H to operate the hands of the clock. Such motors may be, and commonly are, equipped with auxiliary gearing, which may be connected to the crank arm l9 one end of which is connected to the motor gearing and the other end of which connects to the mirrors I3 and I4 so that, when the motor mechanism I8 is in operation, the crank l9 connected thereto will move the mirrors as shown in dotted lines, Figure 1. From this it will be apparent that one motor device IB may be used to operate the clock and also move the mirrors.
The motor I8 is connected to a source of current supplied via the wires 20 which also connect to means for illuminating the mirrors comprising the lamps 2! and 22. The rear casing 23 encloses and surrounds all of the parts being connected in any suitable manner to the front casing I0.
26, Figure 4, so that these hands may be secured to and removed from the shafts Hi from the front of the device. This is accomplished by sliding the glass front I I out of the casing I0, then removing the hands. This permits the withdrawal of the mirrors l3 and 14 through the door 12 in the casing H) or through a similar door (not shown) in the top of the casing. Without this provision for detaching the hands it would be necessary to open the rear of the device and disassemble the driving shafts l6 from the clock mechanism. I
The'numerals for the clock face may be placed on the rear mirror 14 as previously described, and the device being as shown in Figures 1 and 3, if looked at from the front without lamps 2| and 22 being lit, will have the effect of an ordinary plain mirror except that the clock hands 25 and 25 will be visible but an observer standing in front of the device would see himself reflected in the front mirror I 3, and the clock numerals shown in dotted lines, in Figure 3, would not be visible.
The lamps 2| and 22 being illuminated, the onlooker would now see the numerals on the clock face, but would not see his own image, as the front of the device, that is to say the front mirror, would apparently become transparent, and if motor I 8 was in operation the clock face numerals and any other indicia forming the sign on the rear mirror It would apparently move in long lines out into infinity.
The operation of the sign, Figure 2, is substantially the same as that just described, except that here the mirrorsl3 and 14 are stationary within the casing. The effect is obtained of repetitive multiple reflections which will apparently move as the observer moves in front of the sign, that is to say the long lines of repetitive images moving 01f into infinity will apparently shift their position as the observer moves in front of the sign. However, if the observer remains perfectly still these images will not move in the sense that the images referred to in connection with the sign, Figure 1,.move.
Assuming by way of illustration that an observer stands in front of the sign, Figure 1, holding a lighted match in his hand, this sign will show the flame image reflected several times and, as the mirrors move, this image will swing backwards and forwards and this will happen Without lamps 2!, 22 being lit, and without any indicia whatever appearing on the sign.
If the observer repeats the foregoing in connection with sign No. 2, the flame image will be re-refi'ected several times but will not move except to the extent that the match is moved by the observer.
In connection with either sign Figure 1 or Figure 2, fioodlighting the sign from the front shows the indicia, if any, on the back mirror, re-refiected several times, and in the same manner as if the lamps 2|, 22 were lighted.
If some object such as a bottle is placed in front of the signs, Figures 1 and 2, and floodlighted, the bottle image is re-reflected several .times, or if a picture is projected on to the front of either sign, Figure 1 or 2, re-reflected images will be produced.
