Application filed January 28, 1926'. Serial No. 84,381."
The objects of the invention are to provide a tone hole structure for saxophones or similar instruments which will not leak, in which the socket and instrument body or branch are practically integral, in which he use of an exposed solderjoint is avoided, in whichthere is an effective baflie to prevent the escape of saliva through the tone hole to the pad, in which the outer surface of the tone hole is so formed that it has an effectively rounded and smooth contact surface for the pad, and in which there is a lining and facing to the tone hole socket of non-corrosive metal or non-corrosive material.
Objects pertaining to details will definitely appear from the detailed description to follow. The invention is defined and pointed out in the claims.
A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawings, forming a part of this specification, in which:
Fig. 1 is a detail transverse sectional elevational view through one of my improved tone hole structures and the adjacent portion of the body or branch of the instrument.
Fig. 2 is a detail showing method of manufacture, being an elevation view showing the body or branch slipped on a mandrel and the tool for cutting the perforation therethrough.
Fig. 3 is a detail diagrammatic View showing the method of forming the socket body from a tube by cutting transversely across the end thereof with a cylindrical milling tool.
Fig. l is a detail elevational View, somewhat enlarged, of the socket body when thus formed and cut out, one end of course being cut square across.
Fig. 5 is an enlarged detail fragmentary view of the non-corrosive metal lining coated with solder on its outer side.
Fig. 6 shows the socket body anchored in place on the branch or body with external dots of solder as a step in the method of manufacture.
Fig. 7 shows the structure of Fig. 6 with the non-corrosive light metal lining inserted from the interior.
Fig. 8 is a transverse sectional view showing the process of manufacture where the branch with the socketand lining are inserted upon a mandrel and a forming die 15 being pressed down to expand the outer end of the lining'to form an outer finish similar to the expansion of one side of an eyelet. I u
The various parts are identifiedbytheir numbers which refer tolike parts in all. of the views. i 1 is. the body'or branch of a saxophone; or other similar musical instrument. 2 is the perforation forthe tone hole structure. .3 is. one of thesaws for cutting such perforation shown in operation in Fig. 2. ,4 is the mandrel for supporting the body during the 7 process, 5 is the'body of the tone hole socket. This is' formed from a tube 6 supported on a mandrel 61, see Fig. 3, and fed end-on to a cylindrical milling tool 7. The milling tool is of the size and form of the body or branch to which the socket is to be fitted and secured.
In Fig. 4 I show one of the sockets with the inner end cut to the cylindrical form.
and the other end cut square across.
8 is the lining which is coated with solder 81 and is out-turned to a flange 82 which projects within the body or branch of the instrument.
In the process of manufacture, after the tone hole socket has been formed as indition and a die 10 with a conformed outwardly curved groove 101 is pushed into the mouth of the lining and expands the same outwardly to give the complete finish to the outer end 83 of the socket, as seen in Fig. 1. This forces the metal outward like an eyelet tool. The whole structure is then subjected to sufiicient heat to fuse the solder and completely solder or sweatthe whole structure together into a substantially integral part. The line of solder 51 and any other surplus can then be removed.
The whole structure is then finished by plating or otherwise.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. In a saxophone or similar instrument, a tone hole structure comprising the combination with a body perforated at the side, of a tubular socket body embracing the same and soldered thereto, a ductile metal lining member with an expanded projecting flange within the instrument and with its outer end outwardly turned and conformed to the socket body to retain the same and form a smooth contact surface for the pad, the Whole being joined by a solder joint at all contact surfaces of said lining and parts.
2. In a saxophone or similar instrument, a tone hole structure comprising the combination with a body perforated at the side, of a tubular socket body, a ductile metal lining member with an expanded projecting flange within the instrument and with its outer end outwardly turned and conformed to the socket body to retain the same and form a smooth contact surface for the pad, the Whole being joined by a solder joint at all contact surfaces of said lining and parts.
3. In a saxophone or similar instrument, a
tone hole structure comprising the combination with a body perforated at the side, of a tubular socket body, a ductile metal lining member with its outer end outwardly turned and conformed to the socket body to retain the same and form a smooth contact surface for the pad, the whole being joined by a solder joint at all contact surfaces of said lining and parts.
4. In a saxophone or similar instrument, a tone hole structure comprising the combination with a body perforated at the side, of a tubular socket body, a ductile metal lining member with an expanded projecting flange within the instrument, the whole being joined by a solder joint at all contact surfaces of said lining and parts.
5. In a saxophone or similar instrument, a tone hole structure comprising the combination with a body perforated at the side, of a tubular socket body, and a metal lining member, the whole being joined by a solder joint. at all contact surfaces of said lining and parts.
In witness whereof I have hereunto set my hand. I
ALFRED J. JOHNSON.
