COMBINATION LOUD SPEAKER AMPLIFIER AND ELECTRIC LIGHT FIXTURE SUPPORT Filed Sept. 24, 1927 7 Y l I5 23 RICHARD H. SEER, F MILWAUKEE, WISCONSIN Application filed September at, 1927. Serial No. 22l,74=6.
This invention relates to combination loud speaker amplifier and electric light fixture supports.
Objects of this invention are to provide a a novel form of loud speaker amplifier which is built as a combined unit with an electric fixturesupport and adapted to be attached to a ceiling in the usual mannerof an electric fixture, and to carry thelamps, pendants,
m or other members usually employed in the fixtures, While at the same time, it carries an amplifier for loud speakers.
Further objects are to provide a novel form of combined electric light support and an am- 35 plifier for loud speakers in which the amplifier is wholly housed within the fixture and protected from dust and damage, and in which a very attractive and pleasing effect is produced.
Further objects are to so construct the combined unit that the sound from the amplifier will be transmitted outwardly at a large number of different points so as to give a free and .unobstructed path for the sound waves outwardly from the amplifier into the room.
An embodiment of the invention is shown in the accompanying drawings in'which:
Figure 1 is a sectional view through the device, such a view corresponding to a section on the line 11 of Figure 2;
Figure 2 is a plan view of the device, with parts broken away.
Referring to the drawings, it will be seen that the usual pipe or hickey 1 projects below 35 the ceiling line 2. This pipe receives the main supporting strap 3 which is held in place by means of a nut 4 screwed upon thevlower end of the pipe. The ends of the strap 8 extend outwardly and downwardly and are provided with terminal outwardly projecting portions 3. These portions receive threaded hollow sleeves or spindles 5 and are clamped in place by means of nuts 6. The spindles 5 are embedded or otherwise secured to the annular base 7 of the fixture. This base 7 may be composed of any of the usual materials used in fixture construction and may be suitabl ornamented. It is preferably provided wit 1 a cylindrical flange 8 which con tacts with the ceiling,.as shown in Figure 1.
Preferably, a plurality of additional sleeves, as indicated by the reference character 91in V Figure 2, are provided and these sleeves may support lamps or carry the conductors for such lamps in the same manner as the sleeves 5.
Two other supporting straps are employed in this construction, namely, an upper strap or unit supporting strap 10 for the amplifier, indicated generally by the reference character 11, and a lower strap 12 for a purpose hereinafter to appear. The straps 10 and 12 converge towards their ends and bov. outwardly adjacent their central portion. The strap 10 is secured by a pair of bolts or screws 13 to the heavy ring 14 of the amplifier 11 to thereby securely hold such amplifier in position centrally of the combined unit. The strap 12 is provided with a downwardly bowed central portion 15 which is apertured and threaded for the reception of the threaded stem 16 of an attaching fitting. This attaching fitting may be a hollowspindle provided with a ring 17, if desired, and may be used to suspend a lamp in the usual manner. It is provided with a flange 18 for a purpose hereinafter to appear.
It is to be noted that the ends of the straps 10 and 12 are secured by means of screws 19 to the strap 10, such screws passing through the inwardly projecting flange 20 of the member 7. I I
The lower member of the fitting is cupshaped and provided with a main body portion 21 upwardly curved at the portion indicated by the reference character 22, and provided with an ornamental central portion 23. It is provided with an annular flange 24 which contacts with the inwardly directing flange 20 of the member 7 and which may be out out, as indicated in Figure 1, for the passage of the straps 10 and 12. The members 24: and 7 are provided with a plurality of sound out- let apertures 25 and 26, respectively. The member 21 is held in place by means of the fitting 16, previously described. The flange 18 of such fitting bears against the lower face of the member 21 adjacent its central portion and as such fitting is screwed into the bowed portion 15 of the strap 12, it draws the member 21 upwardly into place and securely retains it.
It will be seen that some of the sound produced by the amplifier unit will pass outwardly through the apertures 25 but that a majority of this sound will pass upwardly and be reflected by the ceiling and thereafter pass outwardly through the sound outlet aperture 26. This uniformly distributes the sound and produces a very pleasing effect.
It will be seen further that the device is extremely attractive in appearance and mechanically protects the amplifier from damage, as well as hiding the amplifier.
Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as thejnvention may be variously embodied and as the scope of such invention is to be determined as claimed.
I claim:
1. In a device of the class described, the combination of an annular member adapted for positioning against a ceiling, a supporting strap carried by said member and apertured for the reception of a conduit carrying pipe, a second strap secured to said member, a sound amplifier carried by said second strap, a cup-shaped member having an annular flange contacting with said annular member, said annular flange having a plurality of sound outlet apertures formed therein, and means for holding said annular flange in contact with said annular member. I
2. In a device of the class described, the combination of an annular member adapted for positioning against a ceiling, a supporting strap carried by said member and apertured for the reception of a conduit carrying pipe, a second strap secured to said member, a sound amplifier carried by said second strap, a cup-shaped member having an outlet flange contacting with said annular member, said annular flange having a plurality of sound outlet apertures formed therein, a third strap secured to said annular member, and a fitting passing through said cupshaped member and engaging said third strap to hold said cup-shaped member in contact with said annular member.
3. A light fixture support and loud speaker amplifier comprising an annular member, means for supporting said annular member from a conduit carrying pipe, a sound amplifier supported within said annular member, and a cup-shaped base supported from said annular member, said annular member and base having means for supporting lighting fixtures.
In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.
RICHARD H. SEER.
