HORN FOR PHONOGRAPHS OR SIMILAR MACHINES.

SPECIFICATION forming part of Letters Pat n N0. 771,441, dated October 4;, 1904:.

Application filed April 14, 1904.

To ntZZ whom, it may concern.-

Be it known that LPETEE (I. N IELSEN, a citizen of the United States, residing at Greenpoint, in the county of Kings and State of New York, have invented certain new and useful Improvements in Horns for Phonographs or Similar Machines, of which the following is a specification, such as will enable those skilled in the art to which it appcrtains to make and use the same.

This invention relates to the horn of a phonograph or other machine of this class; and the object thereof is to provide a horn for machines of this class which will do away with the mechanical, vibratory, and metallic sound usually produced in the operation of such machines, and also produce a full, even, and continuous volume of sound in which the articulation is clear, full, and distinct.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of myimprovement are designated by suitable reference characters in each of the views, and in which Figure 1 is a side view of my improved phonograph-horn; Fig. 2, an end view thereof; Fig. 3, an enlarged section on the line 3 3 of Fig. l, and Fig. t a longitudinal section on the line 4: 4 of Fig. 3.

In the practice of my invention 1 providea horn (1/, provided at its smaller end with the usual nozzle-piece (f, by means of which connection is made with themachine, and in the form of construction shown a supplemental piece a is employed between the larger or body portion of the horn and the nozzle-piece o but the parts a and a may be formed integrally, if desired, and maybe constructed in any desired manner. The main part a of the horn is bell-shaped in form and tapers outwardly gradually from the part a to the larger or mouth end (0*, and this curve or taper is greater or more abrupt adjacent to said larger or mouth end. The body portion of the horn is also composed of a plurality of longitudinal strips 1), which are gradually tapered from one end to the other, and which are connected longitudinally, so as to form longitudinal ribs each of the strips 6 being provided at Serial No. 203,080. (No model.)

its opposite edges with a flange L, and these flanges of the separate strips are connected to form the ribs 6 The body portion of the horn or the strips bare composed of sheet metal, and it will be observed that the inner wall of the body portion of said horn in crosssection is made up of a plurality of short lines forming substantially a circle, and it is the construction of the body portion of the horn as hereinbefore described that gives thereto the qualities which it is the objects of this invention to produce, which objects are the result of the formation of the horn or thebody portion thereof of longitudinal strips 7) and providing the outer surface thereof with the longitudinal ribs 5 and curving the body portion of the horn in the manner described. If desired, the part a maybe formed integrally with the body portion of the horn, in which event the ribs 7/ would extend to the nozzle or connecting portion (4 and it is the longi-. tudinal ribs 5* which contribute mostly to the successful operation of the horn, said ribs serving to do away with the vibratory character of horns of this class as usually made and do ing away with the metallic sound produced in the operation thereof.

My improved horn may be used in connection with phonographs or other machines of this class, and changes in and modifications of the construction described maybe made without departing fromthe spirit of my invention or sacrificing its advantages.

Having fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

l. A horn for phonographs and similar machines, the body portion of which is composed of longitudinallyarranged strips of metal provided at their edges with longitudinal outwardly-directed flanges whereby said strips are connected and whereby, the body portion of the horn is provided on the outside thereof with longitudinally-arranged ribs, substantially as shown and described.

2. A horn for phonographs and similar machines, the body portion of which is composed of longitudinally -arranged strips of metal provided at their edges withlongitudinal outwardly-directed flanges whereby said strips are connected and whereby, the body portion points Where said strips are secured together of the horn is provided on the outside thereof being provided With longitudinal ribs, subwith longitudinally-arranged ribs, said strips stantially as shown and described. being tapered from one end of said horn to the In testimony that I claim the foregoing as 1 5 other, substantially as shown and described. my invention I have signed my name, in pres- 3.
