To all whom it may concern:
Be it known that I,.ADLPH G. KAUFMAN, a citizen of the United States, and a resident of the borough of Manhattan, city, county,
and State of New York, have invented certain new and useful Improvements in- Sound-Horns,
specification.
My invention relates to horns for amplifying, purif ing and distributing sounds and of which the following is a V is applica he to apparatus of various kinds and receive sounds.
as to occupy less space;
ble horn, Fi
Reference is to be had to the accompanying drawings in which I have shown various forms of sound horns, embodying my present invention.
Figure 1 is a side elevation, showin a dou- 2 is a front elevation thereof; Fig. 3 is a ront elevation of a triple horn; Fig. 4. is an elevation of a quadruple horn; Fig. 5 is a separate view of one of the horns, the same being given a peculiar S-shape, so Fig. 6- is a front view of a triple horn, differing from that shown in Fig. 3 Fig. 7 is a bottom view of another type of quadruple horn, and Fig. 8 is a side view of the horn shown in Fig. 7 5 Fig. 9 shows a nested triple horn, and Fig. 10 shows a nested double horn. 1
It has been found in practice that a horn of a given size and shape will respond better to certain notes than to others and will therefore emit such notes more .loudly. Speaking in a eneral way, a small horn is better adapted or high notes and a big horn for low notes. When it 'is desired to use the same horn for high notes and low notes, it is often found that the result obtained is not satisfactory at the employment of several horns of di erent sizes, located at different places, has sometimes been resorted to, as 1n the telharmo.
of the larger horn nium. With my present invention a sin is sound-producin source will be found su cient, whether t e notes be hi h or low.
accom lish this result by, com ining two or more orns, preferably of different capacities or qualities in such a manner that they I will receive the .terminating above the small one.
the telharmonium, and the all, and to remed this sound from the same source. The larger horn will ive the proper volume to the low notes, whi e the smaller horn, or horns, will insure the proper value to the high notes.
' In Figs. 1 and 2 the larger horn A and the small horn B are so arranged that their mouths or outlets extend substantially parallel to the receiving end A, the larger horn The connection between the small .horn and the larger horn is made through an openin B in the side of the larger horn. Each 0 the horns is tapering and curved and the outlets are located at a higher level than the receiving end A, although I do not wish to restrict myself to such an arran The receivlng end A is either simp y held against the mouth of the speaker, when the device is used as a megaphone, or connected with the proper part of a telephone receiver, talking machine reproducer, or other instrumen In Fig. 3 I have illustrated a triple born with a large horn C facing forwardly and two small horns D directed to the sides. The inlet connection C is directed downwardly.
In Fig. 4: there are two large horns E, facing in opposite directions, and two small horns F, also facing in opposite directions, but at right angles to the horns E, E and preferably at a different (lower) level. Each of the small horns F connectswith the sound conduit of the larger horns. There is a single sound receiving connection E from which the sound reaches all the horns. form of each individual horn may be varied and in some cases where it is desired to avoid too great a projection of the horn from the wall or instrument, .form, shown-in Fig.
5, may be adopted for the individual horns or some of them.
The triple horn shown in Fig. 6 differs from that illustrated in Fig. 3 chiefly b the.
fact that the central horn G is directe upward instead of forward, the lateral horns H being of substantially the same arrangement and connected above the inlet connection'G'.
' In Figs. 7 and'8 I have illustrated a uadruple horn with individual curved an tapering horns I, directed downwardly and each connected with a common central reement.
The
the particular S-shaped with the sound conduit G at a point slightly described each of ceiving connection I which faces upwardly. The individual horns may be alike, as shown, or of diiferent sizes.
In the forms of of the multiple horn is entirely outside the other elements of the horn.
In ,Figs. 9 and'10 I have illustrated two forms of nested horns, where one element is within another. Fig. 9 shows three horn elements, J, J, J nested one within the other, and all receiving the sound at the end J and dischargingit forwardly, each horn corresponding in shape substantially to the horn A in Fig. 1. In Fig. 10 the horn has two members K, K, one within the other, and provided with a receiving'end or connection K which is horizontally disposed, while the other ends of the horn are shown facing upward. Braces or distance pieces, J K may be employed in these two constructions and the inner horns may project beyond the outer horns at the outlet, although this is not absolutely necessary.
Actual trial has shown that the provision of two or more horns preferably of different qualities or sizes in connectionwith a single receiving connection or end common to construction hereinbefore the 1nd1v1dual memberseeaam them, improves the results considerably, as
regards the even reproduction and spreading connection is equal in diameter to the inner end of one of the horns. The inner ends of all the horns are adjacent to each other and by nesting the horns as in Figs. 9 and 10, I am enabled to place their inner or narrow ends in the same plane.
I .claim as my invention:
A sound horn comprising a plurality of nested tubular elements, the wide end of the inner element projecting forward of the element surroundin it.
In testimony w ereof I have hereunto signed my name in the presence of two subscribing witnesses.
