BELL MUTE FOR CORNETS. APPLICATION FILED JULY 9, 1908.

Patented Feb. 9, 1909.

luveutoz Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed July 9, 1908. Serial No. 442,741.

To all whom it may concern:

Be it known that I, CHARLES G; CONN, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Im rovements in Bell-Mutes for Cornets, of w 'ch the following is a specification.

In the drawing, Figure 1 is a side elevation of a mute, embodying my invention; 2 1s a longitudinal cross sectional view of the same.

1 represents the mute which is shown as substantially pear shaped. The smaller end of the mute is adapted'to enga e the walls of the bell tube of a-cornet, an to provide a tight joint between the walls of the comet and the mute, I secure a piece 3 of soft leather, felt, or similar material, whereby a strong frictional joint is secured.

4 is a tube 0 en at both ends and of less diameter than the diameter of the body of the mute, which extends .throughout the len th i 'of the mute and projects as at 5 slightly eyond the enlarged; end of the mute wherein it is secured. heinner end 3 of the tube 4 extends inwardly to a point adjacent to the inner end of the mute -and in consequence of its position, serves to give egress to a certain portion of the sound waves which enter the air chamber of the mute.

.. The mute is provided with a series 'of threaded tubular o enings 6 near its lar er end, said openings ein provided with at annular seats7. The t readed portions of ring an said openings are above the seats 7. 8 is a ring having exterior screw threads and an annular flange 9 adapted to engage the screw threads in the Wall of the openings.

10 is a piece of membrane or silksecured to the bottom of the ring 8 and adapted to be clamped between-the inner edge of the the seat 7. a

' In order to glve brass wlnd Instruments a 'reedy tone, that they may be used as subreedy quality of tone can be variedby using dilierent kinds of material for the parts to be inserted in the mute. For instance, the use of silk gives a softer quality of tone than the gold beater skin or membrane. Any material or substance which can be vibrated as the sound waves pass over it will produce a difierent quality of tone than that of the natural instrument, even when muted.

While I have shown a particular construction of mute, I do not wish to be limited to the details of construction, inasmuch as I believe that my invention is of such sco e as to cover the use of one or more suitable material inserted in a bell mute for musical instruments for the purpose of changing the quality of tone. 1

What I claim is:

A bell mute comprising a ear-shaped body rovided in the enlarge thereo with threaded tubular openings havin flat annular seats at the inner ends of said. tubular openings; and threaded rings ada ted to screw into said tubular openings to c amp various materials therein.

CHARLES G. CONN. In presence of two witnesses'- W, J. GBONERT, Gnsrnunn S'rnEeo.
