MUSIC-AL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 718,388, dated January 13, 1903.

Application filed September 30,1902. Serial No. 125,417. (No model.)

T0 on whom, it pea/y concern:

Be it known that I, ALBERT SOHOENHUT, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Musical Instruments, of which the following is a specification.

Myinvention relates to that form of musicalinstrument familiarly known as a tubular bell, used principally inchiming-clo'cks,

although applicable for other uses that may readily suggest themselves.

The object of my invention is to improve bells of this general character for the purpose of increasing the tone and resonance of the same and at the same time reducing the vibrations usually present in ordinary bells of this character when struck by the hammer.

My invention is fully illustrated in the accompanying drawings, in which Figure 1 is a sectional view of a tubular bell made in accordance with one part of my invention. Fig. 2 is a similar view illustrating another form of tubular bellembodying my invention, and Figs. 3, t, 5, and 6 are views illustrating forms of tubular bells in which are embodied the features of my invention as shown in Figs. 1 and 2.

In myimproved form of tubular bell I propose to stiffen the ends of the same by grooving or otherwise shaping the ends of the same with a suitable tool, upsetting the metal wall 1 of the bell, as shown at 2 in Fig. 1, which action forms an annular groove on the exterior of the tubular bell and an annular rounded rib on the interior of the same. This groove and rib is preferably semicircular, although it may be angular, if desired.

In lieu of stiffening the tube by grooving the metal of the same I may upset and turn in the ends in the manner shown at 3 in Fig. 2 by spinning or otherwise, effecting the same result as the grooving of the tube after the manner shown in Fig. 1. In some instances I may employ more than one stiffening-groove, and in Fig. 3 I have shown the end of a tubular bell in which three grooves are formed.

In Fig. 4 I have shown a tubular bell in which the features of the bells shown in Figs. 1 and 2 have been combinedviz., the turning in of the end illustrated at 3 in Fig. 2 and the forming of the groove 2 shown in Fig. 1 near such end and in the usual way. This form of procedure provides additional stiffness and effectually prevents any vibration of the bell.

In the tubular bells shown in Figs. 1 and 3 the grooves are separate and distinct, and particularly so in Fig. 3, each groove being separated by a straight wall of metal l. Fig. 5, however, I have shown a form of tubular bell that has been corrugated near the end for the purpose of stiffening the same. It will be noticed that the straight wall of the tube is curved in and out to form the series of corrugations 5.

In Fig.6 a further modification embodying my invention is shown. In this view the ends of the tubular hell are stiffened by turning in the ends of the tube byany approved method, this turned-in portion extending for some distance and being flattened against the inside wall of the tube, (shown at 6.) It will be understood, of course, that each end of the tube is provided with the stiffening means illustrated in Figs. 3, 4, 5, and 6. The tubes will be suspended by a suitable cord 7, as shown in Figs. 1 and 2, such cord being attached in the usualand well-known manner.

In Fig. 1 I have illustrated a hammer 8, arranged to strike the bell, This hammer may strike on either side of the groove, although it is preferable to strike the bell at a point between the groove and the end of the tube. Hammers may also be provided for striking the opposite end of the tubular bell on either side of the groove or other stiffening means.

I am aware that it has been proposed to stilfen the ends of bells of this character by welding rings inside and outside the ends of the same, that it has also been proposed to stiffen the ends by riveting or otherwise fastening a cross-piece within the tubes, and that, further, the ends of such bells have been stiffened by spinning the metal to reduce and round the end of the same. The feature of my invention, however, lies in'the factthat the bell is stiffened directly by manipulating or acting upon the metal of which it is composed and by changing the position and shape of a portion of this metal, thereby increasing the rigidity of the bell and preventing undue vibration when struck by the hammer. There is no additional part or member to be added ISO to the tube; but it forms in itself a complete bell having a through-opening from end to end, insuring perfect tone and resonance.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. A tubular bell having reduced portions intermediate the ends of the same, said ends extending in the fulldiameter of the tube beyond the reduced portions.

2. A tubular bell having stifiened portions formed by upsetting and contracting the body of said bell adjacent to the ends of the same, said ends extending in the full diameter of the tube beyond the stiffened portions.

3. A tubular bell having its ends stiffened by upsetting and contracting the body of said bell, such stiffened portions being Within the terminal lines of said ends which extend beyond the stiffened portions in the full diameter of the tube.

4. A tubular bell having a stiffening band or zone formed by upsetting and contracting the metal of which the bell is formed, such stiffening portion lying between the ends of the tube, said ends extending in the full diameter of the tube beyond the stiffened portion.

5. A tubular bell having a stiffening band or zone intermediate the ends of the same, such stiffening-band being formed by upsetting and contracting the wall of the bell within its terminal lines, the ends of the same extending in the full diameter of the tube.

6. A tubular bell having integral stiffening means formed directly within and upon the metal of the bell intermediate the ends of the same, said ends extending beyond the stiffening portions in the full diameter of the tube.

7. A tubular bell havingintegral stiffening means atornear the ends of the same, formed directly Within'and upon the metal of the bell, said ends extending beyond the stiffening porlions in the full diameter of the tube.

8. A tubular bell having stiffened portions formed by upsetting and contracting the metal at or near the ends of the same to form an annular groove on the outside and an annular rib on the inside of the tube, said stiffening portions being Within the terminal lines of the ends, which ends extend beyond said stiffening portions in the full diameter of the tube.

9. A tubular bell having portions of the metal of which the bell is composed upset at two or more points, such upset portions being contracted to stiffen the tubular Wall of the bell,the ends of the same extending beyond the upset and contracted portions in the full diameter of the tube.

10. A tubular bell tapering from end to end and having reduced portions intermediate said ends, the latter projecting beyond the reduced portions in the normal diameter of the tube.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALBERT SCHOENHUT.
